In this era when transportation means are all about walking and horses, road surveying is much simpler, and there is no need to map the data such as terrain, landform, landform, wires, elevations, terrain, bridges and culverts, and routes like later generations.

As long as you meet the basic terrain and landform, the next thing will be simple.

After reading the book for a while, Li Zheng drank two more eye drops to relax his somewhat dry eyes.

Sooner or later, I must not have myopia, although I have had this idea more than once.

But it seems that this day is getting closer.

Taking notes on several key points of road surveys, Li Zheng took out the process technology development of glass from the system library.

Only when you use the book, you will regret that you have little or no knowledge. The process of absorbing knowledge is always boring and boring.

This feeling is the same as cultivating immortals.

When you learn a skill, your level will be a little higher.

The only disadvantage is that long-term addiction can easily leave many problems.

For example, shoulder vertebrae, lumbar vertebrae, and eye problems.

Of course, when you learn knowledge and learn the skills in knowledge, your abilities will also go to a higher level.

Mouu wore a Taoist robe and left the Taoist temple with a group of children.

He gave the Taoist temple a sum of money to repay the shelter during this period.

In the Tang Dynasty, I finally had my own traces and a true identity as the Tang Dynasty.

Now even the accent of speaking is no different from that of people in Guanzhong.

Even if I talk to people on the street, I can't hear anything unusual.

Mr. Mo is a title for staying in the Taoist temple.

Mouu brought a group of children to Chang'an City and talked to the officers and soldiers guarding the city for a few words.

He took out the official plate given by the Taoist temple, and the officers and soldiers guarding the city let it go.

Since the Buddhist sect caused trouble.

Most people in the court and the people were a little shirkable to monks and even kept a distance.

Although Your Majesty has not stated that he would ban Buddhism or deal with Buddhism.

But now I have been controlling the number of Buddhism.

His Majesty even supported the Taoist sect. Among the Taoist gentry in Chang'an, Yuan Tiangang, Sun Simiao and Li Chunfeng were more famous.

Li Chunfeng's mathematics skills, Sun Simiao's medical skills, and Yuan Tiangang's celestial phenomena.

When the people in the market came to their senses, they found that Taoist priests were much better than those monks who beat wooden fish all day long.

Some people also say that Li Zheng is also from Taoism.

It is said that Sun Simiao is now in Jingyang and once wanted to accept Li Zheng as his disciple.

Li Chunfeng is also in Jingyang.

But Li Zheng never said that he had something to do with Taoist sect.

Nowadays, his reputation in the court and the Taoist sect is much better than that in Buddhism.

As long as you wear a Taoist robe, you won’t have too many interrogations from the official discs that the Taoist sect have taken out.

This is also due to the fact that Your Majesty has always supported Taoism.

Mouu feels that his new identity as a Taoist priest is very useful.

I brought the children to a residence in Chang'an, which was my former residence in Chang'an.

In the West City of Chang'an, there are three houses here.

He gave his wife and children a set of living. When he was buying and selling weapons, Li Zheng gave him all the money he gave to his wife and children.

Now that I have been dead, I have vomited my identity.

I don't plan to go back again if I vomit silently.

What they left behind was enough to live a wealthy life for a long time.

Watching the children enter the yard, they need to prepare some things before entering Tubo.

The children are very sensible and start cleaning when they enter the house. They have indeed not lived here for a long time.

I smeared the table and the thick dust.

The door of the yard was pushed open, and a group of officers and soldiers came.

He whispered and asked, "Is this all for everyone?"

The officers and soldiers who came looked around and said, "We are from Jingzhao Mansion, is this house yours?"

Mouu quickly took out the land deed and said, "This is the land deed. I bought this house two years ago. It is also the land deed approved by your Jingzhao Mansion."

Several officers and soldiers took the land deed and looked carefully, and saw that the person who approved it was Li Chongyi.

They looked at each other and said with a smile: "Don't be surprised, this guy, it's just that no one lives in this house for a long time. Someone specifically asked us to take care of it. You thought it was a thief. Now it seems to be a misunderstanding."

Seeing that the attitudes of these officers and soldiers have changed a lot, they are so vicious when they first came here, and now they are so polite.

The officers and soldiers in charge took out a letter and said, "That's right, someone paid me to take care of this house, and said that if the owner of this house came back, I would like to hand me over the letter to you."

I took the letter silently.

The officers and soldiers returned the land deed to Mo'u, "I'm disturbing."

After saying that, they left the house.

I don’t dare to ask too much about some things, and I still need to have a vision when doing things in Jingzhao Mansion.

Some people can provoke, while others cannot provoke.

Anyone who appears at the foot of the emperor of Chang'an City may be the powerful.

Although the approval of the land deed will be passed through Jingzhao Mansion, most of them will be passed once, and it is approved by ordinary civil servants.

The fact that the young Yin of Jingzhao Mansion was able to be approved by him shows that the owner of this house is quite famous.

Either they have a friendship with the Prince Chongyi or have a relationship with someone who is better.

You still need to understand the interests of being a servant in Chang'an.

Mouu opened the letter and looked at the contents above, with only time and place.

In fact, when I bought this house, it was arranged by Xu Jingzong.

In other words, only Chang'an Ling and Xu Jingzong knew that they lived here.

I walked out of the house and came to the west market and bought some meat and vegetables.

I had a good meal with the kids in the evening and stayed here overnight.

The next day, he vomited silently and left the West Market.

Come to a tavern in Pingkangfang and sit down.

Let the guy serve a plate of lamb and some wine.

Just drinking alone.

It took about half an hour to see Xu Jingzong.

Seeing him sitting in front of him, he vomited silently, "It's been a long time since I saw you."

Xu Jingzong ordered a bowl of mutton soup and a cake, and said while eating, "When will you leave for Tubo?"

I sniffed and drank a sip of wine, "I'll leave tomorrow, I'll prepare some more."

Taking out something, Xu Jingzong put it in front of the silent swearing and said, "This is called a compass that allows you to find direction in the desert."

Mouu picked up the box, the size of a palm, opened the lid to make a compass, and there were two needles on the compass.

Xu Jingzong continued: "The red needle points to the north, and the black needle points to the south."

He nodded silently and put the small box in his arms.

Xu Jingzong took a bite of mutton soup and breathed comfortably, "There is an army in the Western Regions, the guards of Jinyang. The leaders are Li Ke, the King of Shu and Wang Xuance, the second captain of our Jinyang Guards. If so, I hope you can take care of it."

He nodded silently, "I understand, I will definitely do it."
