Li Chengqian went out of the Liangyi Hall and took the car back to Zuochunfang in the East Palace, looking for someone to lead him to the place where Qiu Shenji interrogated, and quietly entered from behind, and saw that Zhang Xingcheng was just sitting next to him and watching and did not interfere in Qiu Shenji's trial, so he was relieved.

After a while, Qiu Shenji's previous interrogation came to an end, and he ordered more than a dozen prisoners to be taken down, Li Chengqian slowly walked out from behind, and Qiu Shenji and Zhang Xingcheng hurriedly stepped forward to salute.

"Flat!" Li Chengqian walked to the main seat and sat down without saying a word, then turned his head and asked Zhang Chengxing: "What did you interrogate in Zhang Qing's family?"

Although Zhang Xingcheng has already taken over as a serious prime minister among the high-ranking officials and servants, he is by no means as tough as the original Fang Xuanling, Wei Zheng and the current Gao Shilian in front of Li Chengqian.

Seeing this, he hurriedly bowed his head and said, "Back to His Royal Highness the Prince, the minister is only here to take a look, and it is all being interrogated by Lord Qiu." ”

Li Chengqian nodded when he heard this, and said in his heart that you know each other, so he turned his head to look at Qiu Shenji.

Qiu Shenji saw that Li Chengqian looked expressionless and said: "Back to His Royal Highness the Prince, a total of 65 people have been arrested to buy grain from the grain store of the Ministry of People's Affairs, and these 65 people have recruited a total of five big grain merchants in Chang'an Chengdong City to raise grain prices, Maotong Grain Bank, Jiqing Grain Bank, Shengfeng Grain Store, Wugu Grain Store, and Jiangnan Grain Store. ”

When Li Chengqian heard this, his face was like frost and said: "Okay! Grab it and roast it strictly, who made them raise the price of grain so high?"

Although he asked his brother-in-law to spread the method of buying low-priced grain from the grain store of the Ministry of Civil Affairs and then selling it at a high price, the sudden rise in grain prices in the past two days should be that there should be someone else behind it.

If there are still the families behind the scenes, they will all be arrested and let them arouse public indignation, and Li Chengqian will be able to submit Yan Lide's request for Guanzhong to reduce the tenant rent.

Li Chengqian saw that there was nothing to do here, so he turned around and went back to the Chongjiao Palace, and as soon as he entered the Chongjiao Palace, he saw Du He and Xue Dading waiting for him.

When Du He and Xue Dading saw Li Chengqian, they hurriedly saluted and said, "See His Royal Highness the Prince!" ”

Li Chengqian waved his hand as he walked: "The two Qing families are flat!" ”

Li Chengqian sat down on the throne in the Chongjiao Hall and motioned for the two to sit down and talk.

"His Royal Highness the Prince, Lord Xue looked at the place that is now being reclaimed and planned a few canals, but some places have to pass through some small hills, we took a look, it will take at least three or five years to dig and open." Du He said that he was very embarrassed, meaning whether he would not dig it or not.

"Can't dig the mountain? Why not take a detour?" Li Chengqian thought it was strange.

Hearing this, Xue Dading hurriedly stepped forward and said: "Back to His Royal Highness the Prince, the minister has seen the ditches that His Royal Highness the Crown Prince originally planned to excavate and where they can't be irrigated, and then plan to dig a few ditches, if the detour will coincide with the ditches originally excavated by His Royal Highness the Prince." ”

Li Chengqian nodded after hearing this, thought about a question and said, "If you dig all the canals you planned, how many more fields can be irrigated?"

"Back to His Royal Highness the Prince, if these ditches can be dug through Longshouyuan, they can at least double the number of paddy fields compared to the current one, but it will take several years to dig." Xue Dading was also a little hesitant as he spoke.

Li Chengqian thought for a while and said, "I understand, you can plan how to go down the river first, and as for how to dig it, I'll figure it out." ”

"Wait for the resignation." Xue Dading and Du He withdrew as they spoke.

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

After instructing the old ghost Li Chengqian, he bowed his head and wrote down the formula and production method of gunpowder, gunpowder is the artifact of opening the mountain, Li Chengqian has always wanted to clean up the Tibet after the road from Guanzhong to Shuzhong is completed, and the gunpowder will be made just now when it is needed.

After a while, Xue Rengui and Pei Xingjian came, and Li Chengqian handed them the formula and production method of gunpowder.

"Your Royal Highness the Crown Prince, what are you doing for us with this?" Seeing Li Chengqian's unfathomable face, Pei Xingjian couldn't help but ask.

"This is the method of making gunpowder, it is a kind of magic weapon, you divide the labor to do this matter, Pei Xingjian, you are responsible for buying materials for production.

Xue Rengui, you are responsible for protecting the workshop that made this gunpowder, and no one is allowed to enter or leave without my permission, and you can find a place to keep all the things that are made, and you can't use a single penny without seeing the handwritten edict of the lonely king. ”

Seeing that Li Chengqian was talking solemnly, the two of them were busy saluting solemnly, and then withdrew to do business.

The two of them went out here, and the inner council of the Taiji Palace over there sent a decree from Li Shimin, saying that Li Chengqian had contributed to stabilizing grain prices and lifting Li Chengqian's ban.

Li Chengqian was very happy when he saw this will, and secretly it seemed that Li Shimin was also cold-hearted, and he obviously liked his talent very much, but he pretended to hate iron but not steel......

Donggong was very happy to get this will, and naturally became more energetic in doing things, through Li Yifu in Chang'an City a few days ago, and now the people of Chang'an know that Li Chengqian sent officials to redress the wrongs, and no matter how powerful this person is, as long as he really violates the Tang law and harms the people, His Royal Highness the Prince can bring him to justice, so the people of Chang'an City have sued.

For a time, some Guanzhong families who were doing evil in Chang'an City on weekdays and some city fox society rats and ruffians were all complaining about their suffering, and these desperately went everywhere and all kinds of relationships in the hope of avoiding this catastrophe, but Li Chengqian sent people from poor families headed by Li Yifu this time, and there were people like Zhou Jin who could not get a position in the imperial examination for several years.

These people have nothing to talk about with the Guan family, so for a while, Chang'an was full of complaints, and some people secretly shouted out such words as 'officials are not boring'.

Li Shimin has a clear view of the situation in Chang'an City, but he has not said anything about it, he is waiting for Li Chengqian to come to his senses, or to be completely defeated by these people and lose everything.

Li Shimin thought about these and sighed in his heart: If people are smarter and can do whatever they want, then how could Emperor Yang of Sui die and the country be destroyed?

After sighing, Li Shimin put down the matter and didn't think about it anymore, picked up the table and played a note, this is a secret music that does not have Tongshang Shu Province and Pingzhang Academy.

Li Shimin opened it and looked at it, and suddenly had doubts in his heart, this is a secret note written by Yu Zhining, which said that Li Chengqian conspired to involve the eldest grandson Wuji and him in the Li Tai rebellion case.

Li Shimin was puzzled when he saw it, he didn't let the second person read the letter Li Tai gave him, and since he got Li Tai's letter, he has been paying attention to the East Palace trial of Li Tai's rebellion, and so far he has not found that Li Chengqian has framed the eldest grandson Wuji and Yu Zhining?

How did Yu Zhining know this?
