Little Shizi started to look at it with a wooden strip, but without drawings, he was completely blindly scheming.

Li Zheng said to her: "Princess Jinyang, don't worry."

I thought it took me three days to complete the work.

Xiao Yizi said, "Then brother-in-law will definitely be able to work together soon."

Li Zheng laughed dryly and said, "That's natural, come on."

"Well! Come on, Minda and put it together."

Little Shizi's little hand clenched her fists to cheer herself up.

When Li Zheng returned to his room, he received a system prompt.

Local re-detection...

Territory: 14,600 acres, with a population of 31,300.

Reward for completing tasks: Library stage three.

New task: Reclaim ten thousand acres of land

Mission reward: Crops in three stages.

Pharmacy Phase II

Crop stage two

The third stage of the library

Let’s not talk about whether this crop has improved high-yield grains in later generations in the third stage.

The 5,000 tons of iron ore in the system space have no place to use.

The pharmacy only has some prescription drugs in the second stage.

The task of reclaiming ten thousand acres of land.

Where did ten thousand acres of wasteland come from?

The tasks given by this dog system are becoming increasingly unreliable.

I only have more than 10,000 acres of land.

Where can I open another ten thousand acres of land? Is it transformed?

It's simply too much!

Only when you use books, you will regret that you will regret that you will regret that you will use knowledge.

Close the door and open the system library.

There are many books in the three-stage system library.

Li Zheng even discovered many academic papers.

There are even design drawings for the steam engine.

Concrete, steam engine, blast furnace iron smelting.

Li Zheng took out a lot of books from the system library.

Begin to add to industrial knowledge.

First, we must make the dam.

Take out a paper on dam records from the 1980s.

Li Zheng began to design the dam.

After half a day, the door was opened.

The little whispered Luban lock came here.

Li Zheng looked at Luban Lock, and the little girl had finished it after only half a day.

Little Vinzi whispered: "Mingda is quite stupid. It took a long time to finish it."

Li Zheng smiled awkwardly, "This..."

Xiao Yizi asked again: "Brother-in-law, how long did you finish it?"

"I was..."

Li Zheng said for a moment, then took out Huarong Road and said, "Princess Jinyang tried this, this is also very fun."

Little Shizi took Huarongdao and looked curiously, "What's this?"

Li Zheng explained: "This is called Huarong Dao. If you move this largest chess piece Cao Cao out, you will succeed."

Little Yizi looked at it, "Mingda will try it now."

Successfully changed the topic.

After sending this little girl away, Li Zheng began to think about the construction of the dam.

The power system is a foundation.

With this foundation, it will be easier to do anything in the future.

Building a dam is a one-time and all-out thing.

Open the construction design drawings of the dam.

Start adding architectural knowledge.

In the next few days, Li Zheng entered a retreat state.

I stayed in a state of being in a closed door for several days.

Prince Li Xiaogong of Hejian sat at home drinking wine.

Cheng Yaojin also sat on Li Xiaogong's mansion.

Looking at Li Xiaogong's complexion, Cheng Yaojin said, "Xiaogong, why are you so bad today?"

Li Xiaogong took a sip of wine and thought to himself that Li Zheng’s medicine was indeed very effective.

I just had some legs weak after using it.

There are dozens of pills, and I have to drain myself if I continue like this.

Do not take it randomly.

Li Xiaogong took out a few blue pills and handed them to Cheng Yaojin, "Old man, do you want to try it too?"

Cheng Yaojin looked at the pills and said, "What are you trying?"

Li Xiaogong handed Cheng Yaojin a look.

They are all rough men. Cheng Yaojin understood it and understood what Li Xiaogong meant.

After accepting it silently, Cheng Yaojin asked, "You look so bad because of this medicine."

Li Xiaogong nodded and said, "Don't use too much, one pill is enough. I'm still a little weak in my legs now."

"Yeah?"

Cheng Yaojin touched his chin with a little doubt.

Li Chongyi has been working in Jingzhao Mansion these days.

Li Zheng’s Chang’an Order is really unreliable.

It has been two years since Li Zheng joined the Chang'an Order until now, he has not been a man for a day.

Today, Jingzhao Prefecture received a case from the Changsun family.

Check out a person called "Satisfied".

Li Chongyi was also curious about why the Changsun family suddenly wanted to investigate this character.

It is not difficult for Jingzhao Mansion to check population and household registration.

Li Chongyi asked the yamen officers of Jingzhao Mansion to check it for a long time but still couldn't satisfy this person.

In other words, this person is not in Chang'an household registration.

Li Chongyi looked at the Jingzhao Mansion Case Library and let a group of yamen servants who had nothing to find left.

There is no registered residence in Chang'an City, and it is very likely that this person is not from Chang'an at all.

There are also people who have no household registration records in Chang'an City, one is the eunuch in the palace, and the other is the Lenniao and the temple people who were bought into the temple.

Li Chongyi came to the other end of the document library.

Here is the household registration of Chang'an Temple people.

The Nine Temples, Five Supervisors and Twelve Guards in Chang'an are all here.

Of course, the more secret files can only be found in the palace.

I was also a little curious. The Changsun family has been very low-key over the years.
