Dunhuafang had already started large-scale development when Li Zhan left Chang'an City and went to Hongtong County. Li Chengqian helped Li Zhan recruit people who could build houses, but these people used cement for the first time, which made these masters a little worried.

After all, cement is a new thing, and the masters have never used it, but once it has been used, the masters still comply with the law of true fragrance.

Cement is stronger and easier to use than glutinous rice mixture. Things that could have been completed in seven days can now be completed in three days. More importantly, cement can be hardened into stone slabs. The appearance of this stone slab is the best material for building buildings.

Stone slabs can be made into beams and put up one by one to form a space, which can continue to lay bricks. In the past, houses were mostly made of wood, because at the productivity level of the stone houses, the poor could not afford the cost of digging stones to build houses, and there was also the fact that cement was not invented very early. The existing so-called cement technology required a higher price, such as glutinous rice juice, egg white, etc., which were not suitable for promotion.

Now with the cheap cement made by Li Zhan, who can use wood?

The house Li Zhan built in Dunhuafang is a pilot project. According to the current community thinking, Li Zhan built a row of four-story buildings in Dunhuafang. These buildings did not cut corners. Now ten buildings have been built. You don’t know that people come to see the buildings every day.

Many people dream of living in it. Of course, these small buildings are first to be distributed to those who contribute to Li Zhan’s workshop. For example, the slave Zhao Dahu, who Li Zhan said will make the slave feel a sense of belonging to Dunhuafang, so Zhao Dahu is the representative.

"Brother... Dunhuafang is getting more and more beautiful, and I always feel that it is different from other places." Li Chengqian walked on the cement road of Dunhuafang with his head tilted, and then looked at the Dunhuafang that was being built.

Li Zhan smiled slightly. Of course, it was different from other places. The houses in Dunhuafang were built according to modern communities, and the greening and other things were also in modern shapes. They were just garbage cans. Li Zhan also designed them like the garbage cans in modern parks.

This is Li Zhan’s little selfishness. He hopes that there is a place in his heart that can be placed in, and these things can remind Li Zhan of the past.

"Brother...!" Li Chengqian and Li Zhan came to the tallest five-story building.

"How..." Li Zhan smiled and looked at Li Chengqian on the side.

"How did you think of so many things, soap, salt, ice, cement, lamb oil candles...!" To be honest, Li Chengqian admired Li Zhan very much. He really wanted to know why his elder brother had so many things.

Li Zhan also looked at the five-story building and smiled softly, "I... I only tell you one person, your elder brother, I have been to the fairy world and have lived there for many years. The things I know are the smallest and simplest in the fairy world.

In the fairy world, there are also big birds flying in the sky, which can fly anywhere in the Tang Dynasty in one day.

A boat without pulp or sail can hold tens of thousands of people.

There is also something called a mobile phone that can transmit voices thousands of miles away and can also capture your appearance, which is much more powerful than my sketches.”

"Really... my god, brother, can you take me to the fairy world too?" Li Chengqian showed a look of yearning.

However, at this time, Li Zhan pulled Li Chengqian to the stone chair on the side and said, "Silly boy, if I could go back, I wouldn't be here anymore. I... can't go back."

"Oh...!" Li Chengqian suddenly felt that his elder brother was a little lonely, so he heard Li Chengqian ask carefully: "Brother, do you really want to go back?"

At this time, Li Zhan pursed his lips and said, "I thought a little, but I know I can't go back anymore, because I should actually have a task for being here. The first task I want to help you become the emperor.

In the second mission, I want to find a woman and kill her.

The third task is to pass on some of the knowledge I learned in the fairy world, such as suture techniques and alcohol. What is beneficial to the Tang Dynasty is just passed on and let the Tang Dynasty develop even more."

"Brother... Actually, you can be the emperor yourself, this way...!"

Li Zhan waved his hand and said with a smile: "Chengqian... Your elder brother's responsibility is not to be the emperor. I also know that what you said is sincere. You are willing to give up the throne to your elder brother, but how should you tell you?

Being an emperor is the destiny of heaven. If the elder brother sits in your position, he will die miserably. You can only sit in this position. This is the way of heaven. Do you understand?

However, there are some people in your way of heaven who want to stop you, so brother, I must stay by your side, protect you, and get rid of these people.

After you become the emperor, I must leave!”

"Leave... Why did you want to leave?" Li Chengqian was obviously a little anxious.

Li Zhan smiled and then touched his brother's head with his hand and said, "You are stupid... If you sit in the emperor, the world will respect you. My elder brother is still domineering to you. When you are unhappy, you will kill me."

"How is it possible? I don't know, I absolutely won't know, brother... don't leave, okay, please." Speaking of this, Li Chengqian's eyes were red with anxiety.

After all, we are only seventeen years old. To be honest, when we were seventeen, who could have been Li Chengqian’s mature experience? Li Chengqian would be good. If it weren’t for the sudden death of Empress Changsun, it was not Li Shimin’s suspicion, and the intentional suppression and using Li Tai as a check and balance, Li Chengqian would not have become what he looked like later.

Looking at Li Chengqian's red eyes, Li Zhan also said in his heart: "Okay... Actually, it's not known how long it will take for you to sit on the throne. Look at His Majesty's current fierceness, maybe he will add dozens of little brothers to you."

"Puff..." This sentence made Li Chengqian, whose eyes were already red, laugh.

"Brother...you dare to joke with your father. You are really too brave!" After saying that, Li Chengqian laughed again and said, "But it's really funny.

My father is really a fierce and powerful person, hehe..."

Seeing Li Chengqian laughing so happily, Li Zhan patted Li Chengqian's head and said, "Okay... I won't say it anymore, it's getting late, let's go to the cafeteria to have a meal together."

"Yeah..." Li Chengqian stood up happily, but just as the two of them got up and went to the cafeteria to prepare for dinner together, a voice had already come from Dunhuafang, that is, Li Zhan came to Dunhuafang this time to discuss who would be given priority to living in the ten new buildings.

You don’t know that at this time, all the residents of Dunhuafang wanted to enter the small building to live.

After all, the environment around the building is very good. Secondly, living in the building is also a symbol of identity. Humans of any era will hope that their identity is higher than others. This is human nature.

Because of this, Li Zhan's arrival attracted the attention of many people in Dunhuafang who are interested in small buildings.
