It can be said that with the method of salt making, the most powerful King Zhao in Zhao and the most favored concubines all received great benefits from Jiang Xi.

As long as Jiang Yu's business of selling private salt is not too big, King Zhao will turn a blind eye.

This is the benefit of bribery.

The Warring States Period was not a later generation with perfect laws. In the feudal period, the king had great power, so what if Lian Po and Li Mu, who held military power, could hedge your military power in just one sentence.

So Jiang Yu has always lived in this era, and he has no sense of security, is very cautious in doing things, and he doesn't even dare to do big business.

But after joining the prostitute, everything became different.

As long as Jiang Yu was not doing too much and was protected by the prostitute, even if someone saw Jiang Yu being jealous, King Zhao would not care.

What's more, the fact that Jiang Yu's selling private salt has not been exposed yet.

After King Zhao's death, if the young master moves to the throne, Jiang Yu will be even more amazing.

Even the power of the government is not impossible.

But at that time, Jiang Yu would find an excuse to let Chang Ji transfer herself to Dai County, north of Zhao State.

In name, of course, it was to prevent the invasion of the Huns. In fact, it was to stay away from the court from now on, be a magistrate in the border, and wait for Qin to destroy the six kingdoms.

When Qin destroyed Zhao, if Jiang Yu was still in Handan, he would not only have to fight to the death with the main force of Qin, but if too many soldiers were killed in the battle, he might be removed from his military power by Qin and brought to Xianyang to serve as an official.

But it’s different with its own territory. Jiang Yu defended the city, and Qin State could not defeat it without hundreds of thousands of troops fighting to the death.

These are two completely different situations.

After Jiang Xi's soldiers learned that Jiang Xi had a way to lead troops to attack Yan next year, they were all so excited. They trained soldiers every day, which was much harder than some time ago.

For soldiers, they may not like war. But for generals, without war, where can there be opportunities for promotion and reward?

Even Jiang Yu did not have military achievements, and he would not be able to get his current position with the title of Li Mu.

Jiang Xi is even a little lucky now, but fortunately he did not enter Qin that year.

Qin State has its own complete military merit promotion system, and the military is controlled by two major families of Wang and Meng families. Jiang Yu would not have the opportunity to enter Qin State at all.

So what if you help Ying Zheng unify the world?

Once you have great achievements, you will be afraid of the monarch.

Instead of living trembling every day, it is better to be the most powerful person in the world and let others live with mercy.

As for the craftsmen, Jiang Xu ordered them to build siege equipment. At the same time, Jiang Xu also informed the craftsmen of the design ideas of the trencher and asked them to develop them.

Jiang Yu has many design ideas, but to really do it, these craftsmen have to rely on them.

Jiang Yu gave them quite good treatment. Unlike the soldiers, these craftsmen have two days off every month to go home. Jiang Yu even promised that when the battle of Yan ended next year and everything settled down, they could build a village near the military camp and take their families over to live.

The last time he went out with Li Mu on the battle, Jiang Yu was responsible for the food and grass, so he naturally got busy early.

But this time the attack of Yan was different. Jiang Yu was the main force in the attack of Yan. He only needed to wait until the food, grass and weapons were mobilized and followed Pang Yu's army to move.

But now it's only October, and there are still four to five months left before going to war next year.

After the siege equipment was built, Jiang Xu ordered the soldiers to build a simple city wall with stones, allowing the soldiers under his command to practice siege day and night.

A few days later, an eunuch came to Jiang Yu's military camp and read out the will of King Zhao.

It is said that this time Jiang Yu was ordered to follow Pang Nuan's army to fight against Yan, and it was the general who was personally ordered by King Zhao in the morning hall.

Not long after the eunuch left, Li Mu led his personal guards and Sima Shang and other generals to Jiang Yu's military camp in person.

Jiang Yu did not dare to neglect and quickly led all the generals of the army out of the camp to greet him.

"Master, why are you here? You don't notify the disciple in advance, so that you can ask the disciple to come and greet him." Jiang Xu said with a grace.

"Haha, if you notify you in advance, you will be prepared in advance. What we see is what you want us to see." Li Mu smiled and said, "If that happens, there will be no intention of investigating."

Jiang Feng glanced at several patrol scouts who were caught by Li Mu's personal guards and smiled and said, "What does that master think of my military camp?"

"How did you build the barracks into a round shape?" Li Mu asked.

"Master, if you lead your troops to attack our military camp, where will you attack?" Jiang Xi asked without answering.

Li Mu looked up at the camp established by Jiang Yu.

The round camp seems to be able to attack from all directions, but in fact the same is true for the square camp.

Both sides of Jiangxiu camp are mountains, not far or near to the camp, and it is a natural barrier. Therefore, when attacking from both sides, the army cannot be deployed, while Jiangxiu's soldiers can stand on the platform and shoot arrows downwards.

But if you attack from the front, this round camp...

Li Mu thought for a long time but didn't find anything strange about this round camp, so he said, "You have chosen the camping place well, but this round camp is nothing strange about it."

"Master, please come to the camp and see again." Jiang Yu smiled mysteriously.

"I even kept my disciples from you." Li Mu chuckled.

After entering the camp, Li Mu looked around, but Li Mu was an ancient man after all, and he did not find any difference between the circular camp.

"Master, when using the same material, the round thing is larger than the square thing." Seeing that Li Mu was still puzzled, Jiang Yu explained: "Master, if I used the same wood and stone to build a square camp, the area in the camp would definitely not be so large."

"Also, round things are stronger and less likely to be destroyed than square camps."

"Oh? There are such benefits?" Sima Shang said in confusion.

"Come on, let the craftsmen create a square iron ring and a round iron ring." Jiang Xu ordered.

In fact, iron products were already available during the Warring States Period, but iron smelting technology was underdeveloped and iron products were rarely used.

There was naturally residual iron material in the army, and the craftsmen quickly built what Jiang Zi needed.

"Master, you can try pinching it hard?" Jiang Xu handed it to Li Mu and said.

Li Mu tried it and found that the round iron ring was indeed stronger than the square one.

"Which egg comes here!" Jiang Xu continued.

"Master, you can try pinching this egg with your hands?"
