Three years have passed since the space. Now Longcheng, the capital of the Dragon and Phoenix Empire, has become quite like a city in later generations. Five or six floors of tall buildings are everywhere. The wide roads, bustling streets, endless crowds, busy construction sites... Everything represents the thriving city.

Since the production technology of power generation technology and equipment has been completely solved, various large power plants have begun to be built in various cities, and various poles and wires are also being tightly laid.

The railway between cities has begun to be built on a large scale, and trains have begun to operate on some road sections.

Military factories, rifles, heavy machine guns, artillery... have been fully mass-produced and have been fully equipped with troops. The Dragon and Phoenix Empire army is transforming into a modern army.

Because of the comprehensive upgrade of steel technology, various heavy industry technologies have broken through bottlenecks and blossomed from all sides. Currently, various qualified medium-sized machinery... radio technology, telephone... various new inventions have appeared in the Dragon and Phoenix Empire in the past few years.

Yang Yuanyuan accompanied Li Yu with a proud look on her face and said, "Young Master! The Dragon and Phoenix Empire has developed well in recent years, right?"

"The development of the Dragon and Phoenix Empire has been good in recent years. Thank you for your hard work." Li Yu went to several cities and industrial areas of the Dragon and Phoenix Empire and was very satisfied after reading it.

Yang Yuanyuan looked at the prosperous and modern city in the distance with excitement and said, "The earth-shaking changes of the whole dragon and phoenix in recent years are just like dreams. I am already dazzled by the sights, and I can report new inventions and new products every day."

Li Yu knew that the technology development of the Dragon and Phoenix Empire had entered the fast lane, so he patted her little hand and said, "This is just the beginning, and you can see more things you can't imagine in the future."

After hearing this, Yang Yuanyuan did not respond, but asked: "The population of the Dragon and Phoenix Empire has increased significantly, and it has exceeded 450 people. Is the army still 3,000 people too small?"

Li Yu thought about it and felt that the population of millions and only three thousand troops was too small. Although there was no war in the space, deep down he wanted to teach the Turks in the future. After thinking for a while, he said: "Let's expand to 10,000 troops for the time being! Try to use soldiers who can practice in the future. I think that except for logistics, soldiers who cannot practice will all retire."

"Ah~~~Young Master, are you planning to form a monk army? But we have 4.5 million people and find out what tens of thousands of monks and soldiers can do."

After being surprised, Yang Yuanyuan spoke again and said, "You named the diesel tractor you want to produce. The prototype has been produced. Do you want to go and have a look?"

After hearing this, Li Yu glanced at the heavy industry manufacturer. After reading it, he shook his head and said, "Don't go and see it. I've seen it here. Let them continue to improve. The whole tractor is a bit bulky. And it cannot be produced independently. Don't forget that the core components in this internal combustion engine are still made with the power of faith."

After saying that, Li Yu looked at Xiaoling who was flying over and asked, "Xiaoling! This internal combustion engine technology has completely room to manufacture independently. How long will it take?"

"Fortunately, since the second generation started working in recent years, the problems that were previously troubled are gradually being solved. Now the main ones are still quite lacking or lacking in precision equipment, various instruments and experimental equipment."

"Do you have any good solutions?" Li Yu heard Xiaoling's words and guessed that she should have paid attention to a lot of faith this time, but she still asked with a smile.

"Hehe! Of course, I have it. I will use all the extra beliefs you have left this time. As long as the core components of the lathe and various instruments, instruments, and experimental equipment that are urgently needed, the small internal combustion engine technology can be completely solved within five years, and the Dragon and Phoenix Empire can completely enter mechanization within thirty years."

It's true!

"Then use it!" Li Yu nodded and said, for the sake of space development, he had to not expand the space for the time being. However, once the practice techniques are popularized among the people of the Dragon and Phoenix Empire, will there be a lot of faith again?

Seeing Li Yu agreeing, Xiao Ling laughed and said, "Master! With those core parts and various experimental equipment, the Dragon and Phoenix Empire finally entered a leapfrog development."

When Yang Yuanyuan heard the conversation between the two, she asked in surprise: "Young Master! Now the Dragon and Phoenix Empire is advanced enough. Do you still think it is slow to develop?"

"Without the internal combustion engine technology, many mechanical equipment cannot be manufactured at all, such as aircraft, various types of cars, various industrial and mining equipment... What's more, without these machinery, how did the Dragon and Phoenix Empire enter the Second Industrial Revolution and then be completely mechanized? Electronic?"

"The second industrial revolution, the complete mechanization and electronicization afterwards?" Yang Yuanyuan repeated what Li Yu had just said in confusion, and then looked at Li Yu and wanted to hear his explanation.

Li Yu smiled slightly and said, "In the future, you will understand that agricultural modernization and industrial modernization will bring earth-shaking changes to the Dragon and Phoenix Empire? I will surely scare you at that time."

After Li Yu finished speaking, he sat there and talked to her about all the incredible changes that would bring about the appearance of the internal combustion engine in the future.

After hearing the changes in the space after hearing, Yang Yuanyuan was surprised and suddenly asked: "Young master, I want to pick up a few relatives. Don't you know if you can live in the space?"

"Of course it's OK! But the time flow here is different from the outside. If they can't practice, their lifespan will be over in less than many years." Li Yu immediately agreed after hearing Yang Yuanyuan's sudden request, but still reminded him.

"I don't think so. When they come here, they have rich spiritual energy and good medical conditions. In the future, their lives will actually be extended, but the time is different from outside. If they can practice, they can live longer."

Yang Yuanyuan said this, looked at Li Yu, and saw that there was no change in his face. He continued, "I think Li Yuan wants to unify the world. I am afraid that all my younger generations will not live long when they are outside, so I just let them be happy in the space for the rest of their lives."

Li Yu knew the direction of history, and nodded without hesitation, and said, "This is OK! I'll let Xiaoling give you permission, so you can bring people into the space freely?"

"Then thank you, Young Master." Yang Yuanyuan put it on Li Yu's body and whispered softly.

Because it was still dark outside, Li Yu did not rush out, but went crazy with Yang Yuanyuan on the bed for two days in the room. After seeing it dawn outside, he hurriedly left the space and returned to the Tang Dynasty.

After Li Yu left the space, Yang Yuanyuan also left the space and used the flying sword that Li Yugang gave him to him, and drove the flying sword towards Chang'an.

...

As soon as Li Yu left the space, he saw Li Feier sitting on the stool in front of the gate looking around. When he saw Li Yu appear, his eyes turned red. He hurriedly stood up and ran towards him. However, he stopped two meters away from Li Yu, but looked at Li Yu silently, opened his mouth to say something, but finally bit his lips and didn't say it.

Although more than four months have passed since the Tang Dynasty, Li Yu has spent nearly four years in the cultivation world, and he still misses Li Feier very much.

"Fei'er, come here quickly." Li Yu shouted with his arms open.

Li Fei'er did not hesitate anymore, and buried her in Li Yu's arms in two steps, hugging her brother tightly, for fear that she would leave again.

This was the first time her brother hugged her like this. While she was so old, she felt happy and shy, she was afraid that outsiders would see her and buried her in Li Yu's arms and didn't dare to look up, but hugged her brother tighter.

"Oh! Who is this? He is actually intimate on the street!"

When Li Feier heard Li Xueyi talking about her, she was so blushed that she didn't dare to come out of her brother's arms. She muttered in a low voice: "Brother, look at this Li Xueyi, I hate it so much."

Li Yu didn't care, and happily patted her on the back, saying, "You will be your brother's wife in the future. What are you afraid of? Don't pay attention to this guy who has no public morality."

After hearing Li Yu's words, Li Feier quickly came out of Li Yu's arms, blushed like a ripe apple, and trotted back home with her head down.

Li Yu looked at Li Xueyi not far from him with an angry expression and said, "What's wrong with you? When you see a man and a woman hugging you, you need to leave quickly, instead of standing there to see. Do you have a public morality?"

"Why are you still blaming me? I was here to see if you have come back. Who knew that you were holding your sister here and don't let go, so you can't say anything?" Li Xueyi complained and laughed.

"How did Li Gui and Hexi Anle Kingdom have been cleaned up?" Li Yu ignored Li Xueyi's nonsense and asked about the situation of the recovery of Hexi.
