The role of the flag is to help the officers and men of the three services to identify the direction, so that the commander can concentrate his forces to attack the enemy's weak points. Zhu Ao divided the flag of Su into red, yellow, green, white, and purple five colors, representing the front, rear, center, left, and right five directions, the meaning of the five-color flag, every soldier must keep in mind, usually train more, if there is a mistake, it is sure to be beaten with a military stick.

Zhu Ao trained his Su army according to the training standards of the modern army, getting up before sunrise every day, and then crossing the country five kilometers in full gear, and failing to eat breakfast. In the morning, he trained in hand-to-hand combat skills such as knives, guns and clubs, practiced archery in the afternoon, and strengthened his soldiers by lifting stone locks and squatting on horses every day.

In order to urge the soldiers to practice diligently, Zhu Ao stipulated that all the troops of the country should take the May Day test and the eleventh big test every month, and the way of the examination is a competition, two people in a group, first fighting, those who win will be rewarded, and those who lose will be punished; Then there is archery, if you win both, you are guaranteed to be given a big red envelope, if you lose both, pout your ass and wait for the board, and you are guaranteed to cry and call your mother.

Under the persecution of this almost cruel training regulations, the soldiers of the Su State spent every day in torture, but they did not resent Zhu Ao, because they all knew that they sweated more in peacetime and shed less blood in wartime, and they resented the Uighurs who were killed by God, and they had to be the enemy of our Su State, and the Lao Tzu suffered so much. Everyone had a fire in their stomachs, and they vowed to break the Uighur soldiers into pieces.

On the morning of 20 March, on the day of the big examination, Zhu Ao personally visited a school outside Zhangye City to observe the examination of the newly built Jingyu Left Guard. Huchen, the king of a thousand households who had made great contributions in the Battle of Jiuquan before, was promoted to the commander of the Jingyu Left Guard, and after knowing that Zhu Ao was going to come to inspect the soldiers he trained, he was particularly attentive, which showed that the prince still valued him very much, and he must take this opportunity to perform well, so as to increase his weight in the heart of the prince.

The way of the exam was that the soldiers fought in pairs, and Wang Huchen first pulled out two thousand households and let them beat each other. Soon, there was a scene of more than 2,000 people desperately beating each other on the huge school grounds, and the dust was very spectacular. Every soldier in order to win the game to get a reward to use all their skills to knock down the opponent, although the exam is a simulation of actual combat, but after all, it is not really life and death, there is a bottom line, the bottom line is not to die, killing people is to pay for their lives, which also avoids some people from being anxious to take their own people as enemies to fight.

The two Thousand Households stood in the middle of this group of people, staring at each other like fighting cocks, after all, they were the ones who were one in a thousand in martial arts, and they were very calm in their moves, and they would not come up and fight like this group of recruits. They all observe the opponent's path first, find out his flaws, and then kill at the first level, which is very clean, because everyone is a master, if you give the other party a chance, you may bury your own life.

These two thousand households, one surnamed Zhang, and the other surnamed Zheng, after looking at each other for a moment, put their right hands on their waists at the same time, and each held twelve points of vigilance, and slowly pulled out their war knives.

Zhang Qianhu and Zheng Qianhu respectively put the war knife in front of their chests, and then drew a circle, approaching the opponent step by step, and after reaching the attack distance, Zhang Qianhu's eyes were sharp, and the murderous aura rose sharply, and a horizontal slash slashed at the opponent, Zheng Qianhu had already taken precautions against this, and a trace of contempt came out of his nose, and he blocked it hard, and then exuded a murderous aura all over his body, and slashed at Zhang Qianhu obliquely.

Zhang Qianhu is also a person who has experienced a hundred battles, and there must be a back move when he makes a move, and he will not rush into it like a recruit, seeing that the opponent slashed hard and diagonally, and twisted his wrist, he stirred up the war knife in Zheng Qianhu's hand, and his face revealed a solemn expression like he was on the edge of the abyss and walking on thin ice, obviously not daring to have a trace of contempt for Zheng Qianhu, an old friend.

The two of them took another step forward, Zhang Qianhu suddenly grinned, but the movements under his hands were still rigorous, and said, "Lao Zheng, the sword technique passed down by your family is nothing more than that." ”

Zheng Qianhu snorted coldly, with an expression of "mom selling batches" on his face, and said unconvincedly: "It's enough to deal with you, a little old man." After that, he bullied forward again, and handed out a knife directly at Zhang Qianhu's heart, the momentum was very fierce, if he was holding a real guy in his hand, then if this knife was stabbed, even if Zhang Qianhu was wearing armor, I am afraid that he would be pierced.

Zhang Qianhu has been on the battlefield for a long time, and he saw the power of this knife at a glance, and he didn't dare to stand in place and use the knife to block, because he knew that the power of this stab was very huge, and he was not sure to block it completely, in case he missed, he would be stabbed in the chest by this wooden knife, the pain was a trivial matter, and the key was that he lost this competition, and he would lose face in front of the prince and the commander, and immediately quickly took a step back, and a lot of the strength of this stab was removed. Pick this thorn of Zheng Qianhu away.

What Zhang Qianhu never expected was that Zheng Qianhu's stab with such a strong effort turned out to be a false move, and before he could take advantage of the situation to counterattack, between the lightning and flint, Zheng Qianhu's single knife that was originally picked up by him actually drew a circle and slashed at his waist sharply.

Zhang Qianhu's tiger body was shocked, the chrysanthemum tightened, and secretly scolded this little old man for being so insidious, if he was hit by this knife on the battlefield, then he would not be split in half. Fortunately, Zhang Qianhu is also a veteran of a hundred battles, although he was a little caught off guard at the beginning, but he often played with others, he practiced an instinctive reaction without thinking, and immediately turned his wrist and thrust the knife downward, and the strength of his whole body was concentrated on the right hand holding the knife, and he blocked Zheng Qianhu's fatal slash.

At this time, only a "click" was heard, and the wooden knives of the two broke at the same time, which had long been expected by the two, such a huge impact force, these two toy knives made of wood can hold up to now.

Although the knife was broken, but the competition was not over, Zhang Qianhu's eyes were fast, he quickly threw away the broken knife in his hand, and smashed Zheng Qianhu's face door with a punch, this punch he made ten percent of his strength, if he hit the target, although it would not kill the opponent, but it was enough to hit him with a blue nose and swollen face, and gold stars in his eyes.

Who knew that although Zheng Qianhu felt a gust of fist wind rushing towards his face, he did not dodge, nor did he block, and a wicked and crazy smile suddenly appeared on his face, and then with a left hand, a cold light appeared in his hand - it was a dagger. Zheng Qianhu grabbed the dagger and went directly to stab Zhang Qianhu's outstretched right arm.
