Li Chengqian went out of Liangyi Hall to take a car back to Zuochunfang of the East Palace, and found someone to lead Qiu Shenji to the place where he interrogated him. He quietly went in from behind. Seeing Zhang Xingcheng just sitting next to him and watching and not interfering with Qiu Shenji's trial, he felt relieved.

After a while, Qiu Shenji's interrogation came to an end. He slapped the agglomeration and ordered more than a dozen criminals to be taken down. Li Chengqian walked out slowly from behind, and Qiu Shenji and Zhang Xingcheng hurriedly stepped forward to greet him.

"Flat!" Li Chengqiantan walked to the main seat without saying a word, then turned to Zhang Chengxing and asked, "What have you all interrogated the Zhang Qing family?"

Although Zhang Xingcheng has already taken over as the senior official and the chief minister of the disciple, he is a serious prime minister, but he is absolutely not as tough as Fang Xuanling and Wei Zheng and the current Gao Shilian in front of Li Chengqian.

Seeing the question, he lowered his head and said, "Go back to the crown prince. I came here just to take the order to see it. It was all questioned by Lord Qiu."

Li Chengqian nodded when he heard this, thinking that you knew each other, so he turned his head to look at Qiu Shenji.

When Qiu Shenji saw Li Chengqian, he said expressionlessly: "Go back to the prince, he has arrested 65 people to buy grain stores in the Ministry of Civil Affairs. These 65 people have recruited five large grain merchants in the east city of Chang'an that have raised grain prices, Maotong Grain Bank, Jiqing Grain Bank, Shengfeng Grain Bank, Wugrain Bank, and Jiangnan Grain Bank. I have sent people to arrest the cabinets and bosses of these grain banks."

Li Chengqian said with a look of frost and said, "Okay! He grabbed it and asked Yan Jiao, who made them raise the price of grain so high?"

Although he told his brother-in-law that he would rush to buy low-priced grain from the Minwu grain store and sell it at high prices, the grain prices suddenly rose so quickly in the past two days, and there should be other people behind it.

If there are still families in Zhong behind it, they will arrest them and make them angry. Li Chengqian can submit the memorial of Yan Lide's request for Guanzhong to reduce the rent.

Seeing that there was nothing wrong here, Li Chengqian turned back to Chongjiao Hall. As soon as he entered Chongjiao Hall, he saw Du He and Xue Dading waiting for him.

Du He and Xue Dading hurriedly saluted when they saw Li Chengqian: "See Your Highness the Crown Prince!"

Li Chengqian waved his hand while walking, "You two families are in a state of peace!"

Li Chengqian sat down on the throne in Chongshen Hall and signaled the two to sit down and talk.

"Your Highness, Lord Xue looked at the place where he was reclaimed and planned several rivers and canals. However, some places have to pass through some small hills. We looked at it and it will take at least three to five years to dig and open it." Du He said in a very difficult situation, meaning that he would not dig anymore.

"Can't dig the mountain? Why not take a detour?" Li Chengqian felt very strange.

Xue Dading hurriedly stepped forward and said, "When you go back to the Prince, I saw that the ditches that the Prince had originally planned to be excavated cannot be irrigated, and then planned to dig a few ditches. If you detour, it will overlap with the ditches that the Prince had originally excavated."

Li Chengqian nodded and thought of a question: "If you dig all the canals you planned, how many more fields can you irrigate?"

"Return to His Highness the Crown Prince, if these ditches can be dug through the Dragon Shouyuan, it will be at least twice as good as the current one. It will only take several years to dig them." Xue Dading said a little hesitant.

Li Chengqian thought for a while and said, "I understand. You can plan the river channel first. As for how to dig me, I will find a way."

"I'm going to retreat." Xue Dading and Du He said and withdrew.

Li Chengqian watched him walk out and said to the old ghost: "Go and spread Xue Rengui and Pei Xingjian."

After instructing the old ghost Li Chengqian, he lowered his head and wrote down a recipe and method of gunpowder. Gunpowder is the magical artifact that can open up the mountain. Li Chengqian always wanted to repair the road from Guanzhong to Shuzhong and clean up Tufan after he had finished it. Now he was just about to use it, so he could make gunpowder.

After a while, Xue Rengui and Pei Xingjian came and Li Chengqian handed them the formula and production method of gunpowder. Xue Rengui and Pei Xingjian took the paper on their hands and looked at it. So they all looked up at Li Chengqian.

"Your Highness, Prince, what are you doing for us?" Pei Xingjian couldn't help asking.

"This is the method of making gunpowder, a magic weapon. You divide the work and do this. Pei Xingjian, you are responsible for buying materials and making them.

Xue Rengui, you are responsible for protecting the workshop that makes this gunpowder. I am not allowed to enter and exit. You find a place to keep all the things you made. You cannot use a penny of the handwritten instructions of the Lone King."

When the two saw that Li Chengqian was solemnly speaking, they both hurriedly saluted and then left to do their business.

When the two of them went out here, the Tai Chi Palace sent a decree from Li Shimin, saying that Li Chengqian had made contributions to suppressing the price of food and lifted Li Chengqian's confinement.

Li Chengqian was very happy when he saw this order. He secretly seemed to Li Shimin was also cold-hearted. He obviously liked his talent, but he pretended to be disappointed...

The Eastern Palace was very happy to receive this order, and naturally he became more excited when doing things. By building momentum in Chang'an City a few days ago, the people of Chang'an now know that Li Chengqian sent officials to rehabilitate the injustice. And no matter how powerful this person is, as long as he really violates Tang Lu's power and harms the prince of the people, he can bring him to justice. So the people of Chang'an City filed complaints one after another.

For a time, some Guanzhong families who usually do evil in Chang'an City and some city foxes, clubs, rats, and hooligans were complaining. These people desperately went to various places and hoped to escape this disaster. However, Li Chengqian sent out this time people from poor families led by Li Yifu, and people like Zhou Jin who passed the imperial examination for several years and could not get a job.

There is no sympathy between these people and the Guan Shi family, so for a while, Chang'an complained, and some people secretly shouted "The official is not in trouble."

Li Shimin was very clear about the situation in Chang'an City, but he kept silent about it. He was waiting for Li Chengqian to understand it in a bloody way, or was completely defeated by these people and lost everything.

Li Shimin thought about this and sighed in his heart: If a person is smarter and can do whatever he wants, then how could Emperor Yang of Sui die and his country be destroyed?

After sighing, Li Shimin put down this matter and no longer thought about it. He picked up a memorial on the table. This was a secret memorial that had not been passed through to the Hepingzhangyuan of the Shangshu Province.

When Li Shimin opened it, he suddenly became confused. This was a secret memorial written by Yu Zhining, which said that Li Chengqian conspired to involve Changsun Wuji and him in the Li Tai rebellion case.

Li Shimin was puzzled after reading it. He read the letter Li Tai gave him and did not let the second person read it. Since he got Li Tai's letter, he has been paying attention to the trial of Li Tai's rebellion in the East Palace. So far, he has not found that Li Chengqian had framed Changsun Wuji and Yu Zhining?

How did Yu Zhining know this clearly?
