It's just that Zhang Chao didn't say what the stone was used for at that time, Zhang Feng and Zhang Shou just protected them, and they gradually forgot about it after a long time.

But the two didn't know that it was not an ordinary stone, but a magnet, which is commonly known as a magnet. Zhang Chao found it by accident, and he didn't know how this thing was formed, and when he saw this thing, he was also very curious, and he also saw that other people didn't know this thing, but he thought that it was a rare thing after all, so he ordered someone to stay.

I never thought that the magnet found at random would be working right now, which is why Zhang Chao is not in a hurry. Even yesterday Xu Chu wanted to send a rescue letter eagle, he wanted to stop it, but after thinking about it, why didn't this mean that it was time to test the reaction of the generals, so he couldn't stop himself.

After resting for the night, Cao Chun must have been a little paralyzed, and at this time, Zhang Chao was going to use the magical magnet to create miracles.

"Okay, it's good that the stuff is there. In this way, pass on my will, the heavy cavalry is ready to attack, 10,000 men are divided into four groups, and attack in the four directions of the south, south, south, and north, and in front of each army, arrange for two hundred soldiers to tie the black stone to the top with long sticks, and then naturally you can suck up the thistles scattered on the ground, and when the time comes, it is time for you to charge in a straight line and give the enemy a head-on blow. Zhang Chao arranged it confidently.

Listening to these words, Zhang Feng and Zhang Shou were also a little puzzled in their hearts, how could that inconspicuous-looking black stone really have such a big effect?

Although they had some doubts in their hearts, it was Zhang Chao's will, and they didn't dare to disobey it, so they immediately agreed.

Seeing that although Zhang Feng and Zhang Shou agreed, they still showed a trace of incomprehension, and Zhang Chao did not explain, he believed that facts speak louder than words. It's just that he still needs to be reminded, so he continued: "Remember, the black stone can suck up the thistle terrestris, only you and those who hold the stone know, other people don't tell the truth, this matter must be kept secret, in the meantime, when the stone is sucked up, you can say to the outside world, this is the destiny of the heavens, so the thistle terrestris does not dare to embarrass you and wait, do you know?" ”

Zhang Chao said with a chattering look that the reason why he did this was that he was also learning from the ancients.

Often the so-called people who have achieved great things will make up a story before the incident, and first mythologize themselves, just like the white snake of Liu Bang, the founder of the Han Dynasty, seems to do so, which can better prove that the will of God is on his side, and also makes the people below more willing to die for him.

Zhang Chao gave orders, and after Zhang Feng and Zhang Shou agreed, they went out to prepare. When the two of them came out of the tent, they saw Zhang Dao, Zhang Jian, Zhang Gun and other generals who were already waiting outside. They heard that the emperor had summoned Zhang Feng and Zhang Shou and hurried without calling them.

Fortunately, without waiting for the three of them to have any questions, Zhang Chaoji in the tent called them in, and arranged for them to be ready to follow the heavy cavalry to follow the attack.

Zhang Chao didn't want the magnet to be known to everyone, so he deliberately concealed it.

Zhang Chao gave orders one by one, and the people below naturally began to prepare, they didn't know how the emperor was going to deal with the thistle terrestris that was spread on the ground for several miles, but they did know that even if the emperor ordered an attack, there was a mountain of swords and a sea of fire in front of them, and they were not afraid.

A loud and urgent horn sounded, and the army of the Celestial Empire's army camp was dispatched, and it was as black as a pine forest all over the field, and there was a black shadow in the formation when you looked at the formation.

The heavy cavalry of the Zhang family was dispatched, and they either held broad-bodied long swords, or meniscus swords, or held giant halberds one zhang long, one by one, like a killing god coming out of hell, rushing out of the camp and heading towards the east, south, west, and north.

The sound of the trumpet in the early morning instantly spread far away on the originally silent land, and this sound also made the surrounding Cao Chun Alliance troops become nervous.

"Is it finally breaking through? Hehe, give the order, the archers prepare, this time I want to see how the so-called invincible army of the Celestial Empire will be defeated by us. After Cao Chun heard the sound of the horn, he also walked quickly towards the top of the tower in Luxian County, and as he walked, he also gave instructions to an adjutant general on the side.

Although Zhang Chao was trapped here with an iron thistle, he didn't think that the other party would be tied up, and then his thoughts, the trapped beast still knew how to fight, not to mention Zhang Chao, who had never had any defeats, if he was appointed like this, it would be difficult to have today's results.

It's just that Cao Chun is not optimistic about Zhang Chao's breakthrough, almost all the thistles in the entire Wei State have gathered in one place, and he doesn't think that anyone can rush out unharmed. When the time comes, he only needs to let the archers shoot on the perimeter, and he may be able to wait for his work and win a brilliant victory in this battle. And once Zhang Chao is taken, Wei will have no opponents, at that time to unify the Central Plains, and even unify the whole country is not a difficult thing, and when Wei wins, his achievements today will forever be recorded in history, and then he will also go down in history.

Just when Cao Chun strode towards the top of the tower in Luxian County, the heavy cavalry of the Zhang family, who were rushing in all directions, had already come to the periphery of the barracks by prancing horses, and came to the front of the thistles everywhere.

"Do it." Seeing the dense tribulus terrestris in front of him, if someone with dense phobia sees it, I am afraid that they can't help but be upset, but fortunately, they can become a member of the Zhang family's heavy cavalry army, which one is not a person with extremely strong psychological quality?

When they saw the thistles spread all over the ground, as soon as a military order was issued, two hundred horsemen rushed out, and they raised the halberds in their hands and swept towards the thistles scattered on the ground.

This is not an ordinary halberd, according to Zhang Chao's order, the front end of each halberd is tied with a magnet larger than a fist, but because the movement is too fast, it does not attract attention.

The halberd swung out and swept towards the thistles that were all over the ground.

Zhang Chao said that this method can be used, but no one knows how, and without practical demonstration, even Zhang Feng and Zhang Shou, who are commanders, are all bottomless. So when this halberd was swung out, they stared at everything in front of them without turning their eyes, as if they were afraid that they would miss something.

Two hundred halberds flashed away in a zigzag, and then a surprising scene appeared, the original four-cornered thistles placed on the ground, still shining in the cold light under the first sun, as if an insurmountable chasm, people can't help but look away.

But as the halberd came out, the thistle terrestris, which was lying on the ground, seemed to be attracted by something, and it actually flew up from the ground and rushed towards the magnet on the halberd.

As if something was attracting them, the thistles, which were difficult to clean up even if they were placed on the ground, flew up one by one, and then were adsorbed to the end of the halberd.

One after another, they jumped up at a rapid pace, but in the blink of an eye, the ground became clean with a length of three meters.

"It's amazing, it's amazing." Seeing this scene, Zhang Feng and Zhang Shou couldn't help but widen their eyes at this moment, obviously the scene in front of them was a little beyond their cognition.

This is the power of physics, and it is only to blame that the technology at that time was too underdeveloped, and some of the simplest knowledge was not known, which is why everyone will be so surprised.

The three-meter-long ground was simply cleared out like this, and the heavy cavalry of the Zhang family army with the halberd were only stunned for a moment, and then they reversed the taste, retracted the halberd, and then smashed it towards the huge pocket on the war horse.

The pocket has been prepared a long time ago, and it is a special place to place thistle, after all, the ironthisle terrestris more than two miles wide is far from being cleaned up by talking, and such an action needs to be continued continuously.

Fortunately, with the previous experience, the heavy cavalry of the Zhang family had confidence, they began to speed up, and the distance of the halberd in their hands became longer, and the effective range of a halberd also increased from three meters to four meters, and then five meters...

With the help of the magnet, the halberd was quickly cleaning the thistle terrestris on the ground at a speed visible to the naked eye, and this scene was also publicized by Zhang Feng and Zhang Shou. What tribulus terrestris will disappear is completely the will of heaven, it is the will of heaven, it is the will of heaven, it is the help of heaven and so on.

After these remarks reached the Zhang family's heavy cavalry, the shock caused was unimaginable.

Originally, these people were determined to die, and they wanted to repay the emperor's kindness with their lives. But now, there is no need for them to do something at all, God will help the second son, what does this mean?

Can anyone veto the will of the heavens? They were glad to have followed a famous lord, a monarch that even God had to choose.

The heavy cavalry of the Zhang family was shocked, and they all thought that they were the embodiment of justice at this moment, and even they were heavenly soldiers and generals to help Zhang Chao fight.

Under this kind of psychology, the morale of the army is soaring, if it weren't for the fact that those thistles have not been cleaned up, I am afraid that they will rush out now and kill all the enemies who dare to block in front of them.

The morale of the Celestial Empire's army began to rise, and the soldiers of Cao Chun's coalition army fell rapidly.

This scene in front of me was seen by many people. When the thistles disappeared one after another like a trick, they were at a loss, they didn't know what was going on, until the earth-shattering shouts from the Zhang Jiazhong cavalry not far away, they knew that it turned out that all this was protected by the heavens and the Celestial Empire.
