"Boom"

In the Yanjing City campus, a thunder roared, shocking Guo Pharmacist who was hiding behind a large wooden shield and heard the sound.

In fact, similar gunpowder weapons are also found in Guo Yaoshi's army. This weapon is called Thunderbolt Cannon or Thunder.

According to historical records, this kind of thunder and iron pottery is filled with medicine, and the cannon fires. The sound is like thunder. It sounds like thunder. It is heard a hundred miles away. It is over half acre of the surrounding area. The fire lit the armor and iron.

This weapon not only had the Liao Kingdom, Jin Kingdom, but also the Dabai Gao Kingdom in the northwest, which all had similar firearms.

However, due to the immature cast iron process in this era, the gunpowder formula has not been optimal, and the refining technology of fire and nitrate is not up to standard, the gap between high-quality fire and inferior fire and nitrate is very large, and the failure to invent granular gunpowder is not invented, etc., the quality of the thunder is extremely unstable, sometimes it can be exploded, sometimes it cannot be exploded, and more when it cannot be exploded.

Since the cast iron shell is difficult to process (it is too thick and cannot be blown up or broken too little, and it is too thin and difficult to produce), craftsmen in the Song Dynasty invented porcelain shells and paper shells. However, because the porcelain shells and paper shells are difficult to withstand the huge air pressure generated by the explosion of gunpowder, they cannot be used to create bombs and can only serve as shells for smoke bombs and incendiary bombs.

The power of smoke bombs and incendiary bombs is not enough to reverse the weakness of the Song army and change the declining national destiny of the Song Dynasty.

As for the use of copper materials with good casting but expensive disposable bomb shells, although the Song Dynasty produced the world's largest copper production in history (the absolute output was more than other countries in the world), because the Song Dynasty's commodity economy was very developed, and copper was the raw material for coin minting.

So, Dasong, who was obviously very rich but lacked money everywhere, was of course unwilling to use copper that could be used to mint coins to make bomb shells.

If Zhao Huan hadn't been "strange" and had someone build 10,000 copper kettles to send to Daming Mansion, it would be difficult for Zhao Kai to push the copper shell and explode the thunder himself. The civil servants below would have strongly opposed it!

But the power of this copper shell thunder explosion is indeed great enough!

Pharmacist Guo followed Guo Tiannu out from behind the shield car, walked more than a hundred steps to the explosion site, and couldn't help but take a deep breath. Around the explosion site, within a radius of 10 or 20 steps, wooden people lying all over the floor, and they were injured.

Guo Tiannu squatted down and helped a wooden man wearing iron armor with force. Then he took a closer look and found a hole on the iron armor that was enough to penetrate two fingers.

The celestial girl pointed at the crack and said to Guo Yaoshi: "Dad, look, if this hits a living person..."

"If you don't die, you will have to suffer a lifelong disability!" Guo Pharmacist whispered, "Look at how about other wooden people?"

"Okay, let's take a look at it one by one." Guo Tiannu knew that her son was extremely serious about military issues.

Otherwise, he wouldn't have asked someone to prepare a dozen wooden men to put on iron armor and place them around the fried pot.

However, the more careful the pharmacist Guo was, the more he knew that the copper shell fried pot was powerful. The outer shell of this copper shell fried pot was easier to break than the iron shell, and the destructive power caused by hitting the target was much larger than that of paper shells and porcelain shell fragments. It was enough to break the armor and fatal!

In order to increase the destructive power of the fried pot, Zhao Kai also made some iron sand and mixed it with gunpowder and stuffed it into the fried pot. This fried pot was a coincidence, enough to put down more than ten people!

"Dad," when Guo Tiannu helped up the last wooden man lying on the ground and asked Guo Pharmacist to check it out, she reminded with a smile, "With the sound of a blow-off pot, no matter how high the martial arts skills or the body is, even the Tiefutu and the Hard Army who can wear two or three layers of armor will die!

This thing is to exchange gunpowder and copper for life. Who in the world has the most gunpowder? Who has the most copper? With the copper produced in the Song Dynasty, it is enough to cast a million fried pots! The output of gunpowder may be smaller, but it is also enough to fill a hundred thousand pots. You have to think it through!"

Pharmacist Guo looked back at his daughter, "Don't say how many fried pots are there in the official family now?"

"More than ten thousand!" Guo Tiannu said, "Dad wants to see it?"

Pharmacist Guo took his eyes off his daughter, "Goddess, what benefits can you get when you run for him?"

"Classic Concubine!" Guo Tiannu smiled and said two words.

Pharmacist Guo nodded, "It's pretty good, then I'll just vote for Da Song again!"

"It's the Great Liao!" Guo Tiannu corrected, "The next time it will be the Great Song Dynasty. All you come and go can catch up with Zhao Yuanfu, the founding hero of the Song Dynasty."

Yaoshi Guo sighed: "I hope I can have a good ending like Duke Wei of Zhao!"

The name of Zhao Yuanfu, Kuang Zan, whose courtesy name is Yuanfu, was the grandson of Zhao Dejun, a great traitor in the Later Tang and Later Jin dynasties. His father Zhao Yanshou was also a great traitor who rebeled from the Khitan. Zhao Zan was powerful and served in the Later Tang, Khitan, Later Han, Later Zhou, and Song Dynasty. It can be said that he was the first surrendering family in the Five Dynasties and Ten Kingdoms! After surrendering, he finally surrendered to a founding hero, to protect the position of Jiedu and Duke of Wei, and died in a prosperous and prosperous state. Zhao Guangyi also stopped court for two days because of his death to express his condolences.

He is really a role model for the surrendered factions in later generations!

Guo Yaoshi first served in the Great Liao Dynasty, then the Great Song Dynasty, three to the Great Jin Dynasty, four to the Great Liao Dynasty, and five to the Great Song Dynasty. He has also made plans in advance for the historical positioning of the five ministers. I don’t know how many days of the big holidays Zhao Kai can take for himself when Guo Yaoshi dies?

It seems that Guo Yaoshi's "bearing leave" has a while, but Gao Qiu and Taiwei Gao's "bearing leave" is not far away.

Just as Guo Yaoshi followed Guo Tiannu to leave Yanjing City and went south to Daming Mansion to apologize to Zhao Kai and Yu Liyan for surrender, Zhao Kai finally approved the official death of Gao Qiu and Taiwei Gao!

Taiwei Gao's "death diagnosis" was sent to Dengzhou for 600 miles in a hurry, and then Zhao Mingcheng personally crossed the sea, sending the "death news" that Taiwei Gao had been looking forward to for almost a year to Shizikou Camp.

The Shizikou Camp has long become a bustling construction site!

The camp for tens of thousands of people is placed on a flat ground surrounded by a series of hills on the north bank of Shizikou, and is being built in a flat land. The civilians recruited from Dengzhou, Laizhou and other places have received double the amount of employment and enough food and drink, so they are very enthusiastic about working.

In just a few months, piers, fences, government offices, streets filled with arrow towers and watchtowers have been built, and a circle of trenches have been built with straw bags filled with soil have been dug out.

However, these seemingly solid defense facilities are only the city defense in the core area of ​​the "Fuliao City" at Shizikou. What is really used to prevent the Jin bandits from attacking is the outer periphery of Fuliao City, which is built along the half-circle of the hill outside the core of Fuliao City, with a moon-shaped comprehensive defense system that is built for 17 miles long.

The so-called comprehensive defense system is of course not a simple city wall, but a castle built on the mountain, including trenches, fences, sheep and horse walls. On every mountain outside the Lion's mouth, a mountain city that can be maintained independently!

At the same time, these mountain cities can be connected into one, forming a system and constructed very cleverly.

In addition to this continuous defense system, the senior high school yaene and others also built a series of cities such as Golden Mountain City, Jiguan Mountain City, Monkey Mountain City (203), Tieshan City, etc.

The three heroes who were responsible for building this defense system were Gao Qiu's third son, Gao Yaoqing, Lu Qian, and Lin Chong, who had guarded Yanjin.

Last time, the three of them were unwilling to die evenly. This time, there were so many favorable conditions, including money, people, and technology (with counterweight guns), and of course they were even more unwilling to die evenly.

Besides, they are not young now and work harder, and they may be important officials and meritorious officials in the future. They are full of energy when they think about it!

Gao Yaoqing, who had just returned from the construction site of the "203 Highland", just as soon as he walked into the somewhat simple Xuanfu Office, he saw his two brothers Gao Yaokang. Gao Yaofu cried and shouted to greet him.

"Sanlang, Daddy's old injury relapsed, the wound burst, the blood flowed, it was gone!"

"Sanlang, you're late, and you didn't even see your father for the last time!"

What? Dad's blood is flowing like a lot? Gao Yaoqing hadn't reacted yet, and was still thinking stupidly: Will dead people bleed? What color of blood?

At this moment, the yamen was already crying!

"Woooooooooooooooooo"

"Taiwei, why are you gone?"

"Taiwei, woo woo"

At this time, Zhao Mingcheng, who looked sad, appeared from somewhere. He held Gao Yaoqing's hand and said, "Yanei, you must be mourning and ordering the emperor to work hard for the country, and he led the way and accidentally fell into trouble. He finally lost his kingly affairs. He is the loyalty and heroic country, and I am a model for my destiny!"

Of course, the story of Gao Qiu's wandering arrows was compiled, but it will be written in history books in the future! This is because Gao Qiu's three filial sons did not want his father to die peacefully, so they insisted on a big show of loyalty to the country.

For this reason, they also discussed with Ma Kuo, Niu Gao and the others and had a not-so-furious battle with the Jin soldiers outside Huacheng Pass. At the end, they suddenly took the banner of Gao Qiu, which scared Wu Qimai so much that they hurriedly guarded the troops back to the camp.

However, shortly after the war ended, news about Taiwei Gao's rushiya began to spread widely in front of the army.

But being hit by the ravine does not mean that you can die immediately. If you want to die, you will be approved by the emperor!

So Gao Yaoqing finally reacted and cried loudly: "Dad, why did you go? The child is no longer alive. The child is going to fight with the golden thief and avenge you!"

Zhao Mingcheng hurriedly comforted the senior high school Yanei and said, "Yanei's mourning and obedience to change. Now the most important thing is to mourn the old lieutenant, and then report to the emperor Ming. He also needs to prepare a written statement for the old lieutenant and explain everything before the Liaodong army."
