Gao Shilian returned to Chang'an City from Shudi today.

The journey of thousands of miles made the old man very tired.

In order to avoid unnecessary "etiquette", Gao Shilian didn't even ask people to report back to Chang'an in advance. Otherwise, if we knew he would come back today, I'm afraid Li's experiment would be postponed.

After all, whether it is empress Chang sun or Wuji Chang sun, even Li Er will personally meet the old man Gao Shilian.

As for Gao Shilian's disciples, old officials, colleagues and friends all over Chang'an City, they will not neglect Gao Shilian because of Li forgetful's experiment.

Gao Shilian plans to quietly return to Chang'an, rest for two days, and then go to meet Li Er.

But as soon as he entered Chang'an City, Gao Shilian felt that his eyes were going to be too busy.

Gao Shilian was in the first year of Zhenguan. He was "denounced" by Li Er to work in Yizhou because he deducted the secret play of Wang Yu, the then Huangmen doctor.

Of course, no one knows what the secret is.

Wang Yu and Gao Shilian have always been friends. Withholding Wang Yu's secret play is not good for Gao Shilian. Gao Shilian was "demoted" as the governor of Anzhou, and then replaced Dou GUI, the governor of Yizhou, and took over Yizhou as the governor of Yizhou. The meaning is worth pondering.

In Li's opinion, Gao Shilian is not so much "demoted" as helping Li Er deal with the trouble.

But anyway, Gao Shilian has not returned for four years since he left Chang'an in the first year of Zhenguan.

In Chang'an City, however, great changes have taken place in the past two years because of Li's forgetfulness.

Whether it's public carriages running all over the street or road toilets all over the streets, Gao Shilian is very novel. The old man even "personally" ran to the road toilet and "experienced" it.

As for other new things, the old man was dazzled and dazzled.

In fact, he heard a lot of things in the chaotang residence newspaper.

But seeing is better than hearing. The content of the residence newspaper has no impact from witnessing it.

When Gao Shilian learned that Li forgot to worry about what experiment he was going to do in the Imperial Academy of the Tang Dynasty today, so Li Er and all the officials ran to the academy to watch, but the old man also became interested and couldn't care about fatigue all the way. He immediately led his servants to Dingzhou village, Huxian county.

After Gao Shilian urged his horse to run on the famous "loser road", he was stunned again.

How could he have imagined that someone really used mirage mud to pave the road.

The output of mirage mud is still not high. At least there is no mirage mud in Yizhou. Therefore, Gao Shilian has only heard of it and has not seen it with his own eyes.

Li forgot to worry and spent a lot of money to build the cement road from Dingzhou village to Huxian County, but it shocked the old man.

The road is as smooth as a whole slate. In the eyes of the Tang people, what a wonder in the world!

Gao Shilian jumped off his horse and squatted down to study the cement pavement for a long time. Instead, a lot of passers-by laughed, and his eyes were full of pride of the woodlouse in the countryside.

After all, like Gao Shilian, almost all the people who came to Chang'an for the first time and saw this cement pavement showed the same performance.

They are not strange to the people of Huxian County, but they inevitably show a trace of pride.

After all, this is the only mirage in the world.

However, with Cheng Yaojin and other big men opening mines in Huxian County, the output of lime is getting higher and higher, and the price of mirage mud produced by the Ministry of industry is also gradually declining.

Li Er has now begun to discuss with Fang Xuanling and others to replace all the main streets in Chang'an city with mirage mud roads.

But the cost of this project is not small. Even if the price of cement has decreased a lot, the budget given by the Ministry of work is still an astronomical figure in the eyes of Li Er and the leaders of chaotang.

Therefore, the matter of paving roads in Chang'an city is still under planning. It is unknown how long it will be possible to start construction.

Because of such a delay, when Gao Shilian arrived at the Datang Royal Academy, he still came a step late. The Academy's hemispheric experiment has ended and all officials have dispersed.

Gao Shilian threw himself into the air, but he was not angry. He visited Nuo University College with great interest.

After learning that Li Er and others were invited to the residence by Li forget worry, Gao Shilian was also polite and took the initiative to visit Li's house.

Li forgot to worry and invited Gao Shilian into the living room. After seeing Li Er, they were greeted again and sat down again.

Gao Shilian was the first to come back to Li forgetful's manor. He was very curious about everything.

After all, the difference between Li forgetful's residence and the traditional residence of the Tang Dynasty is too great. Just sitting on the sofa under his ass makes the old man very uncomfortable.

Tang people are used to kneeling. This soft and elastic sofa is very uncomfortable for Gao Shilian.

But the old man must admit that sitting on the sofa seems really comfortable

"Ziyou, when I came back to Chang'an today, I found that I underestimated you when I was in Yizhou. If I knew you had these skills, I had to let you stay in Yizhou more time to help me."

"Hehe, Gao Gongmu praised it."

Li Er answered with a smile: "my uncle hasn't been in Chang'an for a long time. I'm afraid he doesn't know how to worry about Zi, but he has a greater ability to cause trouble! I'm a headache for this son!"

Privately, Li Er also called Gao Shilian uncle with his wife, empress Chang sun.

His words made Cheng Yaojin, Fang Xuanling and eldest sun Wuji laugh.

Li Wangyou could make complaints about his nose, but he could not help but feel it.

But who makes the world big? Li Er is the biggest. He teases himself, but he can only bear it.

When empress Chang sun learned of her uncle's visit, she hurried over with a group of ladies and Su Changqing. When she saw Gao Shilian, she burst into tears.

The elder sun Wuji and the elder Sun Queen's brother and sister were brought up by Gao Shilian's uncle. They naturally have deep feelings with Gao Shilian.

Even though the eldest grandson queen is already the mother of four children, she is still like a little daughter in front of Gao Shilian.

After Gao Shilian was relieved for a while, empress Chang sun stopped crying, but still stared at her husband angrily. Naturally, she complained that he took her uncle so far away from Yizhou that she couldn't meet for four years.

Li Er was annoyed by his daughter-in-law's resentful eyes and quickly changed the topic.

"Uncle, haven't you tasted the food of Ziyou family? I'm afraid uncle doesn't know. Now everyone in Chang'an city knows that Ziyou family's food is unique in Chang'an. Even in my palace, it's not as good as it is. Today we'll eat a big family and have a good tooth beating ceremony. We have the right to receive wind and wash dust for uncle."

Fang Xuanling and others also nodded in succession.

Cheng Yaojin, a shameless old man, shouted, "Ziyou, are there any cattle in your family who accidentally stumbled and fell to death today? You have to let Gao Gong taste the roast beef with potatoes!"

Li forgetful worry, Li Er, Fang Xuanling and others all look black... NIMA, this shameless old hooligan, wants to drive him out.

If you want to eat beef, how can you ask so openly?

Li Er's face was stiff. He turned his head and talked to Gao Shilian.

Li forgot to worry and turned his eyes silently. He reached out to summon the old housekeeper Li Heng and asked him to see if there was a cow in the house today who "accidentally slipped and fell to death"

The people sat down again to talk, but Gao Shilian said something, which made Li Er angry and almost killed him. They caught Li forgetful and beat him 30 big boards
