Yu Sheng looked at Huang Yuchen who was a little confused and said softly: "You have just entered the meridian space and your strength has increased greatly. You have to face the enemy who is several times more than me later. Your formation talent can play a crucial role."

Huang Yuchen lowered his head and pondered for a moment. He had no idea how much he could improve himself. However, he had carefully considered the use of formations to defend against enemies.

Before, the battle situation was unknown on the hills. The main purpose of setting up the Lihuo Array was to stimulate the flames of the Lihuo Array and introduce them to the battlefield below to achieve the effect of killing the enemy. Later, it accidentally resisted the enemy's sneak attack. After the last battle, Huang Yuchen had some new ideas on the application of the Lihuo Array.

The Lihuo Formation is the simplest and most direct one among the Five Elements Formation. The Lihuo Formation carved on the ground absorbs and refines the fire-attribute elements in the surrounding natural forces and stimulates them. The fire-attribute flame can reach several feet high; and this flame has no foundation and is extremely difficult to resist. Huang Yuchen used the Lihuo Formation to kill a senior warrior cultivator in the enemy army, and he could know the power of the Lihuo Formation.

This formation is portrayed on the ground and can erupt a few feet away. If it is portrayed on the city wall, it cannot be inspired a few feet away forward. If it is activated when the enemy attacks the city, its power is unimaginable.

Huang Yuchen whispered: "General, if you portray the Lihuo Formation on the city wall, it can play a crucial role."

"It's good." Yu Sheng patted the battlements and said, "But the city walls of Changxiangcheng are not stone structures, but simple brick and wood structures. They are afraid they cannot resist too much reaction force of the Lihuo Formation. If there are too many formations and the enemy is activated at the same time, we will smash the city wall ourselves. Can you control the time of the formation to stimulate?"

Huang Yuchen nodded and said, "This is of course possible. If the general thinks this is feasible, then I will do it now." After that, he was about to go down to the city.

"What else do you do except this Lihuo Formation?" Yu Sheng grabbed Huang Yuchen and asked.

Huang Yuchen thought for a moment and said, "Five-combination Formation, Si Shui Formation." Huang Yuchen spoke out two formations, saw Yu Sheng's face slightly thoughtful, and continued, "But these two formations are used to trap others, and there is no immediate effect of Lihuo Formation."

"So, you go and arrange the Lihuo Formation first." Yu Sheng looked at Huang Yuchen and said, "Time is tight, and the enemy will arrive from time to time. You must be fast."

"Don't worry, General!" Huang Yuchen nodded and immediately got off the city wall.

The sky is getting brighter and brighter, and a dazzling light can be seen on the mountain peaks to the east. The sun has risen and the morning is coming.

Huang Yuchen went straight out of the back door of Changxiang City. On the grass outside, countless enemy corpses were lying everywhere. At this moment, the blood had already dried up and the ground looked black. Huang Yuchen had no expression on his face. He came to the edge of the city wall, raised his fighting spirit, and quickly portrayed the Lihuo Formation with his hands on the city wall.

He was very fast. During his previous practice, all the details of the Lihuo Array were already familiar with the heart. He had carved six Lihuo Arrays on the hills, but it did not take much effort. At this moment, his hands quickly slid, and talismans appeared clearly on the city wall, composed of Huang Yuchen's fighting spirit, embedded in the Changxiang City Gate.

Huang Yuchen only felt that his fighting spirit was coming. After carving the three Lihuo Formations, he did not feel any sign of lack of fighting spirit in his body. Instead, the waves were endless.

The light yellow Dou Qi entered the Hunyuan Array from the second meridian, and then entered the first meridian, continuously supporting Huang Yuchen's use. His hands moved rapidly, and each of the Lihuo Arrays quickly appeared on the city wall.

Changxiangcheng is not big, and the back gate wall is at least one mile. It is not long before Huang Yuchen has moved to the back gate door, and carved two formations on the gate, and continued to move towards the side wall.

Yu Sheng stood on the city wall, looking at Huang Yuchen's skillful techniques and rapid speed, he was secretly surprised. The black-armored soldiers defending on the city wall were all shocked. They knew that Huang Yuchen was following the army as a formation artist, but he had never seen him arrange the formation with his own eyes. Now, the speed of Huang Yuchen's arrangement of the formation was like holding a written formation in his hand, directly pasting it on the city wall. The speed was so fast that it was shocking.

Looking at Huang Yuchen's slightly tender face, all the soldiers were shocked. He was so young that he had such a formation ability, which was really unheard of.

The formation at the back door was quickly arranged, and Huang Yuchen kept walking straight to the front door. At this moment, the sound of a low horn came. Not far away, countless gray armor figures slowly appeared in the jungle.

"Enemy attack!!"

The messenger roared and spread throughout Changxiang City. All the soldiers resting on the city wall immediately stood up and looked into the distance.

At the front and back doors of Changxiangcheng, countless enemy soldiers appeared along the official road and the jungle, with neat steps and slowly moving forward.

From a distance, it looks like a cloud of gray, giving people a sense of depression.

Huang Yuchen didn't care about the enemy and did not look back. At this moment, he came to the front gate of Changxiang City and quickly portrayed the formations on the city wall. The speed was significantly accelerated, and each formation quickly appeared on the city wall. A fire formation was portrayed by Huang Yuchen in just a few breaths and embedded in the city wall.

The rest of his life arranged the defense of the back door, walked into the city, and headed straight for the front door.

Changxiangcheng has a unique terrain, as if stuck in a valley. The front door is opposite the enclave Guanlu. There are not dense jungles and grasslands on both sides of the Guanlu, which are much wider than the back door. Relatively speaking, the front door may encounter much more enemies than the back door. It is also difficult to defend.

The enemy had not attacked the front gate of Changxiangcheng before, probably because he wanted to lure Yu Sheng to lead the army to break through the front gate, but the offensive at the back gate was really vulnerable and did not pose any threat to Changxiangcheng. The competition for hills on both sides was not effective. Therefore, the enemy changed its strategy and the army was approaching.

The gray-armored sergeant moved forward slowly and stopped moving one mile away from the city gate. The soldiers behind followed one after another, in a mighty way, and there were countless enemy troops.

In Changxiangcheng, according to Yu Sheng's arrangement, temporary city walls were also built on the hills on both sides, opposite to the city gate, and one brigade was responsible for each front and one back. The offensive and defensive battles and hilly battles in Changxiangcheng are probably the top priority.

The enemy stopped and slowly began to arrange the formation. Yu Sheng narrowed his eyes slightly and carefully watched the enemy's arrangement of the formation. He found that the enemy's steps were uniform and fast, and the quality was not comparable to that of the enemy he had encountered before.

At least, the enemies you can see at present should be elite soldiers of the enemy and have very strong combat power.

The enemy was arranging the formation. Huang Yuchen had completed the formation of the front gate wall. The front gate of Changxiangcheng opened slightly. Huang Yuchen flashed and entered Changxiangcheng. His steps were fast and he climbed the city wall in a few steps.

When he arrived beside Yu Sheng, Huang Yuchen's breath was stable, his face was not red, his heart was not beating; Huang Yuchen had carved a total of twenty fire-free arrays in the city walls at the front and back doors, but he did not feel any consumption. Even he was a little surprised with such endurance.

But it was not the time to be surprised. The enemy troops in front of them had already arranged the formations, and the neatly arranged square formations were arranged without any sign of sight.

The main gate of Changxiangcheng is facing the Guanlu Road in the enclave. At this moment, the enemy generals, including the Guanlu Road, are blocked, and there are stretching hills on both sides.

The sun finally appeared on the distant peaks, and the dazzling sunlight shone directly over, illuminating everything in front of you.

In front and behind Changxiangcheng, pairs of enemy soldiers were arranged in neat square formations, with gray armor, large black shields, and long swords and halberds in their hands, shining brightly.

Whether in the city or within the enemy's phalanx, every soldier held his breath and concentrated, and the battle was about to break out.

Yu Sheng quickly analyzed the situation in front of him.

Changxiangcheng happened to be in the middle of the official road, so it was impossible for the enemy on both sides to pass through Changxiangcheng to send messages. Then, the enemy at the front and back doors would not be commanded by a general, and would be less than the city in terms of dispatch. This may be the only place where the enemy side of the country has advantages for the rest of their lives.

But just looking at the enemy in front of you, the enemy in front of you is vast. I am afraid that there will be no less than ten thousand people, while the enemy in the back door is only a large number of enemy troops.

It is roughly estimated that the enemy's troops dispatched this time were about 20,000, which is several times more than the more than 3,000 black-armored sergeants defended in the city.

Although I had expected the number of enemy troops before, Yu Sheng still frowned when he saw it directly.

Before the battle started, the pressure brought by the enemy was overwhelmed. This momentum was not comparable to that of the previous miscellaneous troops. Not only the rest of his life, but other soldiers guarding the city also felt the pressure coming.

"Dong, dun, dun."

The dull drum sound came from the enemy's phalanx. Yu Sheng looked forward and saw that the enemy's formation was in the middle, with flags waving. Here, it should be where the enemy generals were.

As the dull drum sounded across the earth, the enemy formation in front of him suddenly separated to both sides, revealing a path in the middle, a neat square formation slowly moving forward.

Slowly, the square formation moved forward, crossed the front row before, and advanced straight towards Changxiangcheng City Gate.

At the same time, there is also a square array in the direction of the back door, which is approaching the city gate.

"Prepare!" Yu Sheng shouted, and all the soldiers were full of bowstrings, waiting for the enemy to enter the range.

In front of me, all the enemy troops were wearing standard gray armor, slowly stepped forward, with a large shield in front and a sergeant behind, each holding a small shield in his hand. At the end of the square, he followed the two teams of enemy troops and carried a ladder.

The sergeant slowly emerged from the enemy formation, gradually accelerating, and steadily approaching the city gate, but his pace was steady and there was no panic.

"Enemy elite!"
Chapter completed!
