Seeing that Chen Yuan's assessment had begun, he couldn't interfere, so the old man could only call his attendants and ask him to tell his family about Chen Yuan's current state, so as not to worry Chen Yuan's elders. As for Chen Yuan's food and clothing for the past three days, it is obvious that the old man is responsible for it.

After choosing the troops and equipping the 5,000 soldiers with weapons according to his own wishes, Chen Yuan issued his first order, that is, to cut down trees! That's right, Chen Yuan distributed all his troops to the dense forest in the north of the city, even the infantry and cavalry, except for the twenty sky knights who were ordered to stand guard in the sky, they all began to cut down trees, and when the wood accumulated to a certain extent, a part of the troops were allocated to transport the felled wood into the city, and so on.

The old man watching from the sidelines couldn't understand the purpose of Chen Yuan's move at all, but at this time, the red side had already taken action, because of the large number of troops and the overwhelming advantage, so the battle experience entered in the Lingxi chessboard chose the most simple and direct way, that is, to launch a strong attack.

In addition to the 3,000 infantry, 1,000 earth knights, and 500 sky knights who were left to guard the city, the red city gathered its soldiers and horses, and a full 27,000 infantry, 5,000 earth knights, and 1,500 sky knights marched towards the blue city led by Chen Yuan. It can be seen that the red side wants to directly fight a quick battle, relying on the absolute superiority in troops, crushing Chen Yuan's only 5,000 troops at one time, in order to create a momentum of a large army pressing the territory, the red side even pulled out the 12,000 engineering logistics troops have pulled out a full 8,000 people, and the infantry is as strong and stubborn as the infantry, and the momentum is approaching the blue city.

After passing through the hilly terrain on their side, the army encountered the first difficulty of the journey. Across the 35,000 men of the red side was the dividing line in the chessboard, which was blocked by a great river from south to north. The infantry and cavalry were all in armor, and the weight of the water was so heavy that there was a bit of a rush that made crossing the river difficult. If this problem is not solved well, the strong attack launched by the red side this time will be disadvantaged.

However, under the calculation of the chessboard, in just five minutes, a solution was found. I saw that all the Sky Knights on the Red side flew to the opposite shore with ropes in their hands, and they fixed the ropes in their hands with sparse trees and large stones on the shore, and guarded the ropes themselves.

Fifteen hundred Sky Knights, in groups of four, pulled up ropes, and engineering logistics soldiers built rope bridges. In just two quarters of an hour, three hundred and seventy-five rope bridges appeared on the river. The main body of each rope bridge is composed of four thick hemp ropes, the lower two are laid with wooden planks by engineers for people to settle down, and the upper two are similar to guardrails to protect and borrow force to prevent soldiers from falling into the water due to shaking. Although the production is relatively rough, it solves the problem of how to cross the boundary river very well.

After another hour or so, the mighty army of the red side all set foot on the other side of the boundary river, which belonged to the land of the blue side. If it weren't for the trembling of the mounts of the Seven Thousand Earth Knights who passed through the river at the end, they would have been faster. It can be seen that these military palace teachers entered into the Lingxi chessboard do have real talents and learning, and can find the most labor-saving way to pass in the shortest possible time, and give full play to the advantages of the Sky Knight, a class that ignores the terrain, and is very good in terms of understanding of the troops and the ability to respond to unexpected problems.

When the Red Army stepped into his territory, Chen Yuan was still directing his men to cut wood. Since this exam tests Chen Yuan's ability as a military commander, at the beginning of the assessment, his consciousness has been absorbed into the body of the commander in the city, and everything is commanded and dispatched from the perspective of real war. When the consciousness is withdrawn, for the sake of fairness, the candidate will not be able to see the division of the enemy's army from the chessboard, and all attacks on the chessboard will be suspended. When the examinee touches the chessboard again, consciousness re-enters, and everything is arranged back to the moment when the examinee's consciousness exits.

That is to say, from the moment Chen Yuan began to command his own soldiers, he lost all his vision on the entire chessboard, and completely became the commander of the blue side in the chessboard, and could only grasp the enemy's movements through the intelligence of the sentinels.

When the 35,000 troops of the red side came to the central plain, the blue knights in the sky finally issued a warning, and reported the enemy's marching speed and strength to Chen Yuan as quickly as possible.

Chen Yuan couldn't help but show a strange smile when he heard the news that the Red Fang army was pressing. He immediately ordered the detachment of 500 infantry to rush back to the city, and the rest of the soldiers stopped logging and hid and rested on the dense forest. He followed five hundred soldiers back to the city.

Standing on the city wall, Chen Yuan saw countless soldiers in red armor from a distance, rushing towards the city where he was located in an orderly manner. When all the horses of the Red side came to the city not far from the formation, Chen Yuan laughed three times and ordered: "Your guests are coming, you are not welcome, come, open the city gates, and follow me to greet the guests!" The only five hundred infantry left in the city opened the city gate wide and lined up at the city gate, as if they really welcomed it.

The old man outside the chessboard almost bit his tongue when he saw the decision Chen Yuan made when the red army was coming. The old man thought that there was something wrong with his eyes. "This kid is going to give up? No, it shouldn't be that simple!" The old man didn't know what Chen Yuan was going to do.

But at this time, the red side hesitated, the Lingxi chessboard did record the confrontation experience and handling habits of several military palace teachers, and the entry was quite complete, so the degree of anthropomorphism of thinking was extremely high. But it is precisely because of his rich military experience and high anthropomorphic thinking that he is more and more vigilant in the face of Chen Yuan's abnormal behavior of opening the city gate and even ordering soldiers to welcome him. As the saying goes, "When things go wrong, there must be demons." "That's what I think about now the chessboard that has the thinking of the military palace teacher.

So the scene was deadlocked, and two hours later, Chen Yuan was still standing at the head of the city with a smile, but the red side did not dare to enter the city. In accordance with the previous military thinking, the Red side sent the Sky Knight to scout the situation in the blue city from the air. However, he found that except for Chen Yuan, who was standing at the head of the city, and the five hundred infantry who were welcomed by the road under the city, the city was empty.

This kind of scene made the red side more vigilant, Chen Yuan has 5,000 troops, except for the 500 at the city gate, and the 20 cavalry in the sky, where did the rest of the people go? What does it mean that the blue side opens the city gate? Is it to paralyze us, and then ambush us in the city, and eat us away little by little? Are there all kinds of traps in the city?

These questions continue to emerge from the minds of the decision-makers on the red side, that is, the chessboard that has shaped the consciousness (hereinafter referred to as the red generals) by entering the mental data of the military palace teacher. The empty city seemed to be covered with countless fogs, and the wide open gate seemed to be a huge mouth, waiting for the Red soldiers to throw themselves into the net. So, after hesitating for a while, the red side chose to retreat, these 35,000 people are the vast majority of the red side's combat strength, if all of them are folded in this city, the strength of the red side is greatly reduced, then it will not take two days, the red side will definitely not be able to hold its own city.

Watching the army in front of the city gate slowly retreat, Chen Yuan calmly got off the city wall, closed the city gate, and continued to cut wood in the forest with five hundred infantry.

The old man was stunned when he watched outside, and when he saw the red side retreating, there was only one thought in his heart: "How is this possible?" but calmed down and thought about it carefully, but he had to be impressed by Chen Yuan's performance. Just as Chen Yuan didn't know the Red Division, the Red didn't know Chen Yuan's Division. Chen Yuan opened the city gate before, and the welcome move of the road was to set up a suspicious array, in order to make the red side unable to figure out the reality of his own side. In this way, the red side will not dare to enter the city easily, lest there be a trap in the city and trap the main force in the city.

This time, the red side attacked strongly, mobilizing 35,000 men, and wanted to complete the battle. In order to increase the speed of the march as much as possible, in order to achieve rapid maneuvering, Chen Yuan was caught off guard, and the army must not bring much grain and grass. But they didn't dare to enter the city, and there was not enough food and grass, so they had to retreat under the stalemate.

This grasp of people's hearts and control of the current situation can be called terrifying, and it is absolutely impossible to make such a move without courage and courage, after all, there are only 500 troops, as long as they make a mistake and take half a step, the entire assessment will fall short. After figuring out the key, the old man's excited eyes lit up, such a whimsical military thinking and countermeasures were all new things he had never heard of, he didn't expect that in this first battle, the two sides didn't even have a small-scale collision, and the red side was directly defeated, which made him start to look forward to the development after this battle.
