It was already completely dark, and the ministers went home one after another to warm their wives and children.

But Li Shimin can't, he must finish today's official business.

So at this time, he was still fighting at night in the imperial study, and there were too many things to be busy with.

There is some not very good news below, although there were two heavy snowfalls in succession a few days ago, but the weather has changed in recent days, and the temperature has risen a lot compared to the same period in previous years.

The snow on the ground has almost melted, which is not good news, and Tobe speculates that the drought may continue next year, and the imperial court should prepare early.

Li Shimin had a headache and couldn't believe it, but he couldn't ignore the suggestions of the ministers, so he approved his own reply on this excerpt and arranged it as appropriate.

Basically, I agreed to the suggestion of the Ministry of Households, but the preparation must be limited, and the Ministry of Households needs to come up with a reasonable plan, and this approval only gives the Ministry of Households the power to prepare the plan, not the final executive power.

Seeing that there was still a thick pile of folds waiting to be dealt with, Li Shimin sighed helplessly, and sighed secretly, it was tiring to be the emperor's mother......

"Your Majesty, King Zhao took the crown prince and a commoner named Chen Ershui to ask to see him outside the palace!"

"Xuan!" Li Shimin slowly put down the pen.

Li Yuanjing has been a little impressed by Li Shimin recently, and the effect brought by the quyuan plough and the waterwheel naturally makes Li Shimin excited, and even recently he is faintly looking forward to Li Yuanjing coming to see him again, maybe he can bring something new.

Thinking of this, the depressed Li Shimin couldn't help but feel a lot better, so he simply sat and waited for Li Yuanjing to forget it.

"Brother Huang!"

"Sons, see the ...... of their fathers"

"The Emperor...... Xiaomin see his father's ...... Ah, no, it's the royal brother...... It's not right either......"

Li Yuanjing covered his eyes speechlessly, looking at Chen Ershui's passionate performance, he couldn't wait to find a place to crack and get the whole person in, it was so special.

This goods and Cheng Chuliang actually have a fight, one is that he doesn't know how to call himself, and the other doesn't know how to call others.

"Hehe, don't be nervous!" Li Shimin smiled comfortingly and comforted Chen Ershui casually.

Knowing that Chen Ershui is a commoner, he may not be very familiar with these etiquettes, coupled with the nervousness of seeing the emperor for the first time, there are two different titles in front of him, and it is normal to follow them.

For civilians who can't read a single big character, Li Shimin's tolerance is quite high.

Even if he scolds him in front of him, even if Li Shimin's anger is like thunder, he will definitely not settle accounts with others afterwards.

But if the person who scolds him is a scholar or a scholar, then hehe, ask for more blessings!

"Prince, have you made your uncle angry again?" Li Shimin looked at Li Chengqian with a straight face, and he found that Li Yuanjing's expression was not quite right.

"Father, the son didn't even have time to say a few words to Uncle Wang, how could he make Uncle Wang angry?" Li Chengqian muttered dissatisfiedly, he obviously didn't answer this pot.

"Brother Huang, this matter has nothing to do with the prince, today the younger brother is here to ask for rewards, money, and power!" Li Yuanjing said directly, he didn't like to go around, he felt too hypocritical.

"Oh? Listen to it! Li Shimin squinted his eyes slightly.

"Chen Ershui, come on!"

"Yes......" Chen Ershui stumbled in agreement, but his mind was full of paste, and he didn't know how to speak.

These things that happened today had too much impact on him, he was an ordinary person without any identity, but he was able to follow King Zhao, and he was taken into the palace to see the emperor on the first day, that is the emperor, and he is the kind that people feel unqualified.

"Forget it, this king will tell you for you!" Li Yuanjing was really a little anxious, not because he was afraid of bad things, but because Chen Ershui was completely out of proportion, and it was impossible for him to complete this task.

Li Yuanjing glanced at Li Chengqian, and Li Shimin instantly understood what Li Yuanjing meant.

"Prince, you step back first!"

“……”

Li Chengqian left the imperial study with a confused, dissatisfied and angry face, didn't he say that he would let the palace follow? Why did you kick the palace open at the critical moment?

Chen Ershui was one of the craftsmen recruited by his brother a few days ago, but in order to avoid people's eyes and ears at that time, he did not announce it to the public, but ordered Chen Ershui to continue to conduct research in secret. The younger brother received a report from Chen Ershui yesterday, saying that the research results had been achieved, so the younger brother took a few little rabbit cubs to the acceptance today...... "Li Yuanjing added fuel and vinegar to tell him what Zheng Ji did at Chen Ershui's house today.

Of course, he didn't hide that he asked Du He to give Chen Ershui a new identity through Du Ruhui.

"What about your findings?" Li Shimin was a little impatient.

He is not interested in these bullshit things, and it is related to the Zheng family, and he doesn't want to care too much, it is not cost-effective.

"A new type of material, if it is used to build a city, it is indestructible, the younger brother asked Chen Ershui, summed up, if there are enough materials and manpower, a city as large as Chang'an, it can be completed in two months at most, if it is a small border town or a military fort, it may take a month in winter, but if it is a field, it will be enough for half a month at most."

"How sturdy?" Li Shimin frowned, this speed is indeed quite shocking, but the effect is only to hear the four words indestructible, the ghost knows what indestructible looks like.

"If you are patient enough, you will be helpless to use the materials of the catapult! What's more, not afraid of fire and water! Li Yuanjing thought about it, I don't know if the shells can be blown up, there are no shells to experiment, and this is only the first generation of products, but the effect is the same.

Li Yuanjing continued: "Brother Chen instantly thought of countless uses, which can be used to repair bridges, roads, and cities, especially in the border areas, and the role is even greater, and the minister defines this thing as a strategic material of the Tang Dynasty!" ”

The role of cement is much more than that, if this is really the case, Li Shimin feels that all walks of life need to use this thing.

But Li Yuanjing is not a good person, and his purpose has been made very clear.

Reward! Ask for money! Demand!

Coupled with the previous words, Li Shimin realized that Li Yuanjing wanted to do something to the Zheng family.

"Is there any evidence for this?" Li Shimin frowned tightly, this matter is a little difficult to handle, but it can't be ignored.

"A few bunnies, as well as the guards, have seen it with their own eyes!" Li Yuanjing nodded.

Li Shimin stood up and paced back and forth thinking, if the Zheng family could move, he would have moved a long time ago, and every family couldn't move.

The advice given to them by several confidants was to use time to weaken the political power of the family through the euphemistic means of the imperial examination, so as to achieve the goal of weakening the family.

This is the only way, and it is also the best way, and Li Shimin also knows very well that if he adopts this step, he is afraid that he will not see this day in his life.

But it can guarantee the stability of the country!

Li Shimin waved his hand at Chen Ershui, signaling him to step back first, and turned to look at Li Yuanjing: "Tell me about your plan!" ”
