After Changyan led the right army out of the valley, about an hour later, a steady stream of things began to be transported in from outside the valley.

After Changyan went out with the right army, Chu Chen did not rest, but chatted with Lu Youzhi for almost two hours before going to sleep.

Early the next morning, Chu Chen walked out of the room, only to see that there were already soldiers gathered on the other side of the playground to prepare for the morning training.

After breakfast, Chu Chen called Lu Youzhi and several generals over.

"I've called everyone over to discuss what we're going to do next. In the conference hall, Chu Chen sat on the main seat, Li Ao and Zhao Ling'er stood on his left and right, and the others sat below.

"Old Lu, tell you about the plan we discussed last night. Chu Chen looked at Lu Youdao.

"Yes, sir. Lu Youzhi got up and began to talk to everyone in detail about what he discussed with Chu Chen last night.

Last night, Chu Chen learned in detail from Lu Youzhi about the progress of the soldiers' martial arts during this time, Lu Youzhi told Chu Chen that during this period of time, although half of the soldiers did not practice internal strength, but one-third of them have initially cultivated internal strength, which is no longer comparable to ordinary soldiers, even those soldiers who have not yet cultivated internal strength are also extremely good at martial arts, and it is not a problem to be ten with one, especially the general and some well-qualified commanders, who already have the strength of the middle stage of internal strength, and can be regarded as a master; Hanshan Pass, far away from Lushan Pass, is the border city of the two countries.

"Sir, Lu Lao, please give an order, with our current martial arts, plus the weapons and armor sent by Mr., we are confident that we can capture Hanshan City in a short period of time!" After listening to the details of the discussion between Lu Youzhi and Chu Chen last night, the right general Liu Xiangdong got up and bowed to Chu Chen and Lu Youzhi.

"Capturing Hanshan City, it will be easy! I am willing to lead the left army to attack Hanshan City!" General Zuo Sima Ming got up and said.

"In terms of strength, my Chinese army is only stronger than your left and right armies, if you want to fight Hanshan City, it should be my Chinese army. Chinese General Lu Dangren said.

"Are everyone willing to attack Hanshan City?" Chu Chen asked with a slight smile when he saw that the three generals were rushing to attack Hanshan City.

"As long as Mr. says a word, we will definitely take Hanshan City in the shortest possible time!" Sima Ming said brightly.

The others nodded their heads in acknowledgement.

"Since everyone is willing, let's attack Hanshan City in half a month, but, in our current situation, if we want to take Hanshan City, we can't attack it, we can only outwit it. Chu Chen smiled and said: "However, before taking Hanshan City, I will pass on a battle formation of the three armies, if this battle formation is used well, 10,000 troops can destroy the enemy's 100,000 army, and my 30,000 army can destroy the enemy's 300,000 army." ”

"10,000 to 100,000, sir, what kind of battle formation is this, so powerful?" Hearing that Chu Chen had such a powerful battle formation, the people around him were all surprised, even Lu Youzhi also shrank his eyes slightly, he also had a certain understanding of the army battle formation, the battle formation was well arranged, it was possible for 10,000 people to trap the enemy's 100,000 army for an hour, but 10,000 people wanted to destroy the enemy's 100,000 army, it was a little difficult, or rather, it was simply impossible, even if their Tianchen army was a martial arts master, but the battle between the two armies was no better than fighting alone, and there were too many accidents.

"This array, I call it the Tianchen Battle Array, it is my first gift to the Tianchen Army. Chu Chen said, as he spoke, Chu Chen took out dozens of pieces of paper from his body, on which he introduced the Tianchen battle array in detail.

The Tianchen Battle Array is a simplified version of Chu Chen's Immortal Array, including killing enemies, defense, etc.

Zhao Ling'er took the paper from Chu Chen's hand and sent it to Lu Youzhi's hand first, Lu Youzhi took the paper, quickly browsed it one by one, and then passed it to others.

"Sir, this battle formation is the strongest battle formation that the old man has ever seen. After reading it, Lu Youzhi got up and expressed his admiration to Chu Chen. "If you follow this formation, don't say 10,000 to kill 100,000, even if it is to destroy 200,000, it won't be a problem!"

The generals of the three armies have not learned the battle formation, so they don't understand it very well, they just quietly listen to Lu Youzhi's words, but Lu Youzhi's words surprised them again, 10,000 to 200,000, then their Tianchen army is invincible?

Chu Chen smiled, just now he said that 10,000 to 100,000 was modest, and he didn't tell the truth, but he didn't expect Lu Youzhi to see the power of this battle array.

"Although this formation is powerful, it also requires all soldiers to cooperate with each other, and only when soldiers can rest assured that they can hand over their backs to their comrades, this formation can exert its true power. Chu Chen smiled and said, "So, in the next time, what the three armies have to learn is this battle formation, when it is practiced, when we will be able to take Hanshan City!"

Next, after Chu Chen learned about the situation of the soldiers in detail with the generals of the three armies, he began to teach everyone to fight in formation, and almost two hours later, the generals of the three armies left.

"Sir, before attacking Hanshan City, shouldn't we send someone to spy on the reality in Hanshan City?" After the generals led out of the council hall, Lu Youzhi said to Chu Chen.

"Of course, when the three armies are familiar with the battle formation, I will personally make a trip. Chu Chen said.

In the following time, Chu Chen personally supervised the practice of the three armies, and if there was anything wrong or inadequate, he would personally instruct, so that after ten days, there was nothing for him to worry about in the battle formation of the three armies.

There is no need to worry about the affairs of the battle array, Chu Chen began to refine the pill with peace of mind, now there are more than half of the three armies who have not cultivated their internal strength, it is time to forcibly improve them, after all, their number is too small, if the Qi State dispatches a million troops at once, they will not be able to stop it, but if every soldier is a master of internal strength, then it is another matter, then his 30,000 Tianchen army can swallow Qi and destroy the Qi State in the shortest possible time.

In order not to have to refine the pill by himself in the future, Chu Chen gathered all the children over the age of ten in the outer valley, selected thirty-two children who were talented in alchemy, and let them learn the art of alchemy by his side.

Time passed unconsciously, and half a month later, all the medicinal materials that Chu Chen brought over were exhausted, and he refined a total of seven or eight kinds of pills of more than 100,000 pills, half of which were used to help soldiers break through their internal strength, and the other half were used to heal injuries and diseases.

After half a month of training, the three armies have become familiar with the battle formation, and the three armies attack each other with the battle formation, and in the melee, they can still maintain the integrity of the battle formation, and all the soldiers are very relieved to hand over their backs to their comrades, which makes Chu Chen very satisfied.
