Before Chu Zheng and Guo Xiang left Xiangcheng, the young commander's escort in Xiangcheng had prepared horses and carriages in advance and had to accompany him to defend him. However, Chu Zheng did not leave them by his side and ordered two of them to go directly to the southern Yunnan to inquire about the so-called Wuliang Mountain Jade Cave location in advance, and the other three took their carriages and horses to wait in the town ahead.

At this time, he and Guo Xiang took a boat to cross the Han River, bypassed Fancheng, which had already been run with the Song army flags, and ran towards Nanyangcheng.

Nanyang City is nearly a hundred miles away from Xiangcheng, and the towns along the way have fallen. Seeing the ice and snow on the ground gradually fading, the Mongolian scouts are no longer affected by the fast horse galloping. From time to time, you can see Mongolian scouts in teams of ten people appearing and fighting with the Song army scouts who came out from Fancheng. The two sides fought extremely fiercely.

All signs indicate that it is only a matter of time before the Mongolian army moves south.

Even Guo Xiang noticed the situation was not good, and she asked with some concern: "My junior brother, will the Mongolian Tartars attack Xiangcheng in the near future this time?"

Chu Zheng said as if nothing happened: "It shouldn't be so fast. The millions of Mongolian troops are advancing westward. The princes Kublai Khan and Ruyang Palace, who were responsible for the south attack, have only 300,000 to 400,000 troops. It is difficult to accumulate and operate food and grass in winter. If they want to attack Xiangcheng in a large scale, they will have to have at least two or three months of preparation time. If we burn the food and grass prepared by the Mongolian army this time, they will have to postpone the attack on Xiangcheng for a long time."

"That's it..." Guo Xiang nodded.

Although she followed Guo Jing and Huang Rong to learn about marching, logistics support, and military strategies, Guo Jing and Huang Rong never told her the latest situation and intelligence, and she felt relieved when she heard Chu Zheng say this.

When Chu Zheng saw the fooling pass, he secretly breathed a sigh of relief.

In fact, the situation is much worse than he said.

Unlike Guo Xiang, he has another intelligence network of the Young Marshal's Army and is very familiar with the changes in the situation.

The battle in Fancheng half a month ago, although it severely hit Mongolia's arrogance, "Wang Baobao" was captured and executed publicly in the square, which greatly boosted the morale of the military and civilians in Xiangcheng and their determination to resist the war, but it also made the Mongolian side angry and regarded it as a great humiliation, and stepped up the pace of invasion.

In the past half month, cars, horses and food from the north continued to gather in Nanyang City. With the previous storage, even if it was conservatively estimated, Nanyang City had enough food and grass needed for 200,000 Mongolian troops in three months, and even dozens of red cannons and tens of thousands of shells. After the ice and snow were completely melted, the 200,000 Mongolian troops would go south and attack Xiangcheng through Nanyang City.

At present, the military and civilians in Xiangcheng are only a few hundred thousand. Except for the elderly, weak, women and children, the total number of strong men is less than 200,000. Among them, only 50,000 well-trained soldiers in armor are only 50,000. In addition, more than 10,000 people from the world who came to help, their strength is also very different from that of the 200,000 Mongolian elites.

As soon as the Mongolian army arrived, Xiangcheng was afraid that it would burn all jade and stones and would be razed to the ground.

The situation in front of him is really bad. If it weren't for this, Guo Jing and Huang Rong would not have rushed to teach all the lifelong learning, sent Guo Polu away, and entrusted Guo Xiang to him.

Chu Zheng sighed inwardly. He knew that he could not persuade Guo Jing and Huang Rong. The current young marshal's army could not provide support under the pressure of the Li family. He could only take risks to give Guo Jing and Huang Rong some help within his ability!

Chu Zheng's target was the food, grass and gunpowder in Nanyang City. As long as he could burn and destroy these food, cannons, artillery shells, the Mongolian army lacked weapons, and the large-scale invasion of the south would have to be delayed for at least a few months, so that Xiangcheng, which had received material assistance from the Young Commander's Army, had more time to train soldiers and prepare for the defense of the city.

As long as the war is dragged to the frosty winter, Xiangcheng will be able to survive for another year of peace.

Therefore, the operation to burn Nanyangcheng this time is directly related to the survival of Xiangcheng and the life and death of Guo Jing and his wife.

Chu Zheng didn't want Guo Xiang to worry, and he didn't want her to take risks with her, so he greatly weakened the significance and risk of this action in front of her.

Both of them were extremely brave in light skills and soon ran nearly twenty miles. At this time, they could hardly see the scouts of the Song army. Instead, the scouts of the Mongolian side were more active.

Chu Zheng was unwilling to alert the enemy, so he pulled Guo Xiang carefully to avoid these scouts.

He had long remembered the Xiangcheng area that Guo Jing and Huang Rong had explained these days, and the sun was the direction sign, so he was not afraid of getting lost.

At noon, the two arrived at a small forest several miles outside Nanyang City.

From a distance, there were many checkpoints and guards on all the roads leading to Nanyang City. Outside the city, flags were waving and the camps were endless. Chu Zheng analyzed the enemy's method taught by Guo Jing, and couldn't help but gasp.

More than 30,000 Mongolian troops were stationed outside the city to guard!

Guo Xiang also has considerable knowledge of military strategy and strategy, and couldn't help but say: "My junior brother, the Mongolian Tartars are so strict that we can't get in at all."

"Well, the situation is more complicated than expected. There is no way to go during the day. At night, I will touch it in and take a look. You and Dongfang Bai are waiting for me here."

Guo Xiang was worried and said, "Young brother, why don't you forget it? Just looking at the outer periphery, you are so tightly guarded, and the city is afraid there are even more masters."

But how could Chu Zheng retreat?

He comforted, "Senior sister, don't worry, what are the mere tens of thousands of Mongolian soldiers? I heard that there is a king of the Southern Court of Liao Kingdom, Xiao Feng, who captured the enemy chiefs alive in hundreds of thousands of troops. If others can do it, I will naturally be able to do it, otherwise the title of "the world's number one master" would be worthy of a false reputation?"

Guo Xiang knew that the junior brother had never liked the title of "the best master in the world". At this time, he was actually used to make him happy. He couldn't help but burst into laughter and no longer forcefully persuaded him, but just repeatedly reminded him to be careful.

At night, the moon was bright in the sky, Chu Zheng changed into a light tight black suit, leaving Dongfang Bai to take care of each other in the woods, used his magical body technique, and quietly entered the Mongolian camp guarding Nanyang City.

Along the way, I saw the Mongolian camps properly guarded, with open and secret whistles overlapping. They were really the first-class elite troops. If others were afraid of quitting, they would have retreated.

But Chu Zheng knew that today's things would advance but not retreat, and he must succeed. He relied on his master's courage and used his unparalleled light skills to quietly break through several camps and come outside Nanyang City.

Lying in the darkness of the snow-sinking area, I saw the city light brightly, and every ten steps is 10 steps and every whistle is guarding even tighter than Fancheng.

Chu Zheng patiently laid in the shadow of the snow for nearly an hour before he seized the opportunity to change his defenses. He climbed over the city wall without knowing it and entered the city.

The Nanyang City is still under high alert, with patrol teams walking around from time to time, and barriers are set up at key intersections, and people keep watch in the high grounds. With such strict deployment, even flies can't escape the guards' eyes and ears.

It can be seen that the guard of Nanyang City is also a very cautious and talented person.

Looking around the world, there is probably no one else who can sneak into Nanyang City under such strict guards.

Chu Zheng no longer relied on his eyes at this time, but instead released his mental power to monitor the distance of a hundred feet around him.

Now with his cultivation level, he can barely use the "Mind Eye 3.0" to replace his eyes with his spiritual sense, but the distance cannot exceed a hundred feet.

With "Mind Eye 3.0", and the Mongolian guards are ultimately humans, not machines, and people will be slack and tired. Chu Zheng walked around the entire Nanyang City without any danger and roughly understood the situation.

In the huge city, there were only three or four thousand surrendered traitors and puppet soldiers, all of whom acted as coolies, while there were more than 20,000 Mongolian soldiers.

All the houses in the northeast corner have been converted into barracks for rest in the army.

The other areas were converted into three large granaries, each with about a distance of tens of thousands of liters of rice and wheat and thousands of loads of forage. They were piled up in various temporary warehouses, with heavy troops guarding all intersections, and various fire prevention measures were quite complete. Open flames were prohibited from being close to the warehouse. Only special lanterns with covers were used, and the light was not bright.

This was actually a convenience for Chu Zheng. With the help of "Social 3.0", he directly touched three large warehouses in the dark and walked around, even finding out the storage places of gunpowder, cannons and shells.

At this time, he was stuck in the darkness of the eaves like a gecko, staring at the large granary in the distance. Even if someone walked past him, even if he raised the lantern and looked carefully, he would not be able to find his traces.

But his face was extremely solemn.

Because Chu Zheng had already discovered that it was almost a fantasy to set fire to these large warehouses by himself and could not have been possible.

The only chance is to detonate the gunpowder shells hidden in the cellar below three large warehouses, but the power of these hundreds of thousands of kilograms of gunpowder exploded is so terrible that most of the entire Nanyang City would collapse. Chu Zheng himself was not sure that he could escape alive in such a big explosion.

He took out his storage bag and inspected it one by one.

The burning of Nan Yangcheng was something he planned during his time in Xiangcheng, so he naturally made sufficient preparations in advance.

There is no shortage of fire-attracting items such as hot tin, torches, flints, etc. in the storage bag.

But several cellars where gunpowder were stored were quite far apart. Even if Chu Zheng could sneak in and explode one of them, the other places would be immediately alarmed. Unless he forced himself to break through, he would not want to blow up the gunpowder in those places.

The problem is that there are tens of thousands of soldiers here. Once Chu Zheng is trapped in a siege, no matter how high Chu Zheng's martial arts are, the true energy of Shenzhao's immortality will never be able to break through the siege. Those who ignite explosives will be lucky to escape from Nanyang City before the true energy is exhausted.

Chu Zheng suddenly remembered the "Nine Yin Scriptures" taught by Guo Jing, and his eyes lit up.

The "Nine Yin True Sutra" is a set of all-encompassing martial arts. The internal strength alone can be called divine level. However, the internal strength contained in the Nine Yin True Sutra is more feminine and soft. Chu Zheng now possesses four magical skills, so naturally there is no need to practice it again.

In addition to internal skills, there are several extremely profound martial arts in the "Nine Yin Sutra", including the "Snake Walking and Cyclops Flipping" method, the "White Python Whip Method", the "Nine Yin White Bone Claw", the "Heart-Destroying Palm", the "Great Demon-Subduing Fist", etc.

But what really attracts Chu Zheng the most about the "Nine Yin Sutra" is the above special exercises. One is the "Yi Jin Zheng's Bone Forging", which can accelerate the cultivation of internal strength and make the internal strength twice the result with half the effort. The other is the "Healing Chapter", which can cure extremely severe internal injuries.

There is also the "Soul Transferring Method", which can be used to deal with people with weak minds or evil thoughts. The "suggestions" are automatically stimulated under specific circumstances, so that they act according to the "suggestions", and afterwards, they will lose all the memories during the Soul Transferring Method.

What Chu Zheng is thinking about now is the "Soul Movement Technique". The "Soul Movement Technique" has amazing effects, especially with Chu Zheng's mental power and internal strength, he is not afraid of being backfired.

The only troublesome thing is that casting spells requires one-on-one with the target person, face-to-face, eye-to-eye casting spells, and the entire process takes as fast as one minute.

But under the current situation, the "soul-transfer method" is the most suitable and useful method.

Chu Zheng made up his mind and sneaked into the warehouse again.

The warehouse was filled with food and hay, and there were only three martial arts masters with low skills hidden in some key places to serve as the final warning and defense force. There were four first-class masters guarding the entrance to the cellar with gunpowder.

This is because the extremely strict guards have no effect on Chu Zheng.

With his ghostly body technique, Chu Zheng easily pointed all the seven first-class masters, then raised the special lanterns they had dropped and cast spells on them one by one, so that when they heard the signal, they would set fire to the gunpowder in the cellar, and set fire to the warehouse everywhere.

It took Chu Zheng a lot of time to cast the spell for the first time. In addition to some people's firm will, Chu Zheng directly summoned He Lan'er and used the poison to erode his mind and mind, and then he completed the casting.

In order to ensure that everything is foolproof, Chu Zheng also sneaked into the cellar and made several ignition lines and poured them with heavy tinder to ensure that the gunpowder in the cellar could be blown up to the maximum extent after ignition.

Finally, he handed the pre-prepared fire-induced materials to the seven masters. Chu Zheng untied their acupoints and gently flicked them in each of them. The seven people woke up from hypnosis, not realizing that they had lost consciousness just now and were hit by hypnosis.

Such a person, Chu Zheng, wandered around in several warehouses with gunpowder buried, and it took him an entire time to prepare.

Chu Zheng touched a tall building and two unconscious Mongolian masters had fallen under his feet.

He was full of energy and shouted: "Chu Loujun is here. The Mongolian Tartars dare to offend our Han territory again in the future. If we kill our Han people, we will be punished by God. Today is-!"

The sound was like a bell, and it was heard from afar, and it could be heard within ten miles of the radius.

——Originally, Chu Zheng wanted to be named Li Jia, which caused suspicion and internal struggle between Mongolia and Li Jia, but when he thought that Princess Shaomin of Ruyang's palace was resourceful, such a plan of framing may not be effective. Instead, it only increased the reputation of Li Jia's anti-Mongolia. It would be better to simply claim his real name. Anyway, he has been a great revenge with Mongolia, and at the same time it can also shock the Mongolian forces.

Sure enough, his shout was like poking a hornet's nest, which immediately caused countless exclamations and riots. Torches lit up everywhere in the darkness. I don't know how many people called the horses neighed, and all the elites came out and gathered in his direction.

Seeing the streets and alleys full of Mongolian soldiers, suddenly a loud noise came from the southeast warehouse, the earth was shaking, and the mountains were shaking, and fiery red mushroom clouds emerged from the entire warehouse, and all the buildings around collapsed, and countless Mongolian soldiers were gathering were killed and injured.

Immediately afterwards, several warehouses in the southwest and northwest also heard earth-shaking explosions one after another, and the fire and loud noise directly collapsed most of the Nanyang City!

The fires soared into the sky, and all the crying and screams were drowned!

The tall building chosen by Chu Zheng was extremely far away from several explosion points and was still shaken.

Chu Zheng felt that it was not enough. He took advantage of the chaos inside and outside the city to ignite fire and ignite most of the remaining food and grass. With his ghostly body skills, he didn't have to worry about being surrounded by mixed Mongolian soldiers.

When he left Nanyang City, there was a sea of ​​fire everywhere in Nanyang City. The fire was so big that this red light could be seen more than ten miles away.
Chapter completed!
