Second, five days have passed, and in these five days, I finally did the promotion of mobile phones.

Gu Sixin took four advertisements for Xingteng Technology, focusing on the four mobile phones and four different fields of Xingteng Technology. At the same time, Gu Sixin also took a lot of promotional photos for Xingteng Technology.

Because of this, Gu Sixin stayed in Xingteng Technology for five days, and after working overtime, she completed these preparations.

Of course, Gu Sixin is not a free endorsement. This time her endorsement was a sky-high price.

The sisters settle the score clearly, and Cheng Yan and Gu Sixin are both very serious about this.

After all these were completed, Cheng Yan and Gu Sixin boarded Du Cheng's private plane and arrived in the capital.

The arrival of the two women made Shuiyuetian Villa a lot more lively.

And recently, Ye Hu and Zhong Yueyi moved here to stay for a few days, and Mr. Ye and Ye Chengtu and others also came, so the excitement was naturally no problem.

What's more, just one day later, Gu Jiayi and Han Zhiqi and others boarded the plane and came to Beijing.

The arrival of Gu Sixin and the others did not affect Du Cheng's arrangements.

He basically spent all his time on scientific research in order to be able to spend more time in two months.

Time flies very quickly, and in a blink of an eye it takes more than ten days.

Du Cheng's scientific research was going very smoothly. With his wholehearted dedication to the research, the entire Blueprint plan progressed very quickly.

But this is exactly what Du Cheng needs, and the reason why it can be carried out so quickly is actually a big reason because of Tang Xinxin.

Tang Xinxin's talent is so good. No wonder she will become a national scientist in the next few decades and make outstanding contributions and breakthroughs in many fields.

With just over ten days of careful guidance, Tang Xinxin's talent in scientific research has been terrifyingly demonstrated. As early as ten days ago, she was able to participate in various research by Du Cheng.

Not only that, Tang Xinxin's ability to understand Du Cheng's technical skills is amazing, even more powerful than the other captains.

Under such circumstances, Du Cheng could have directly asked Tang Xinxin to carry out some research, and he only needed a little guidance.

Because of this, the entire scientific research process suddenly accelerated a lot.

In the past, Du Cheng basically ran back and forth in every laboratory like a firefighter. Now, with Tang Xinxin here, he can almost concentrate on conducting several important research.

This result made Du Cheng very happy because he knew that as long as Tang Xinxin was cultivated, his time in the future would be much easier.

Zhijian's research this time was able to complete it about half a month in advance.

And in the past half a month, a major decision was made at the same time.

Li Dang was very quick and he started working on Kaijing Energy after he took office online.

It took him just over ten days to circle a piece of land with an area of ​​over 2 million square meters near Dongqiao Harbour in Ningde as an industrial area of ​​Kaijing Energy.

This is a huge project. Although this one is very well built, it requires two small hills to level and two small villages to move.

Ningde has shown great welcome to this.

Such a large project will be a revolutionary impact on Ningde's industry. It will increase Ningde's industrial output value by several levels.

In addition, such a large-scale project can also solve more than tens of thousands of jobs.

Similarly, such a large-scale project will also be accompanied by the emergence of many small industries, which is undoubtedly an excellent opportunity for Ningde.

This project was started by Cheng Zhunye, so Du Cheng was not worried about anything.

With Cheng Zhunye in there, all this can undoubtedly be accomplished very well. Therefore, although Cheng Zuoye has called, Du Cheng was lazy to go to Ningde. Instead, he devoted all his thoughts to scientific research and tried to complete the things at hand first.

This scientific research process lasted for more than half a month.

With the deepening of scientific research, Du Cheng felt that his decision was undoubtedly very wise. Tang Xinxin's growth made Du Cheng only describe it as overjoyed.

From Tang Xinxin, Du Cheng saw Gu Sixin's shadow. He only needed to train them appropriately, and their growth would shock the whole world.

In this little while, Tang Xinxin already has the ability to stand alone. The progress of the entire blueprint of the entire blueprint has increased by nearly one-third.

Originally, Du Cheng thought that the research on the Blueprint plan would not be completed until the end of next year, but now, it may be completed in June and July tomorrow.

The current research is that Du Cheng himself presided over several of the most important research, and the rest were basically left to Tang Xinxin to take charge.

With good understanding, Du Cheng's technical resources were very good at Tang Xinxin's hands, and he could organize scientific researchers to complete them well, which immediately relieved Du Cheng's affairs.

After more than forty days, Du Cheng finally completed almost all the research at hand. At least, he can rest assured to give himself a few months of vacation. Some small research can be completed by the scientific research base by himself. Even if there are any problems that cannot be solved, they can still be solved through video conference.

"Xinxin, are you really planning to celebrate the New Year here?"

After packing up his own things, Du Cheng asked Tang Xinxin who came to see him off before leaving. Tang Xinxin shook her head and said, "No, I'm just waiting for New Year's Eve before going back. Everyone is on holiday during the New Year. Why do I? It's useless to stay here.

Du Cheng thought about it, and just now he thought that Tang Xinxin was planning to strengthen politics here during the Chinese New Year, so just because Tang Xinxin said this, he said directly: "Well, then the matter here will be left to you. If there is anything, call me.

Over the past few days, he has seen Tang Xinxin's seriousness and hard work. It can be said that Tang Xinxin not only has a terrifying talent, but her seriousness and persistence, as well as her hard work, is also much better than others.

Without a natural genius, just like Gu Sixin, if you don’t make absolute efforts, no matter how good your talent is, it will be wasted.

"Okay, Brother Du, don't worry

Tang Xinxin smiled sweetly on her face. In this time, her relationship with Du Cheng was very cold.

Of course, this closeness is limited to colleagues.

Du Cheng said nothing, and after saying goodbye to Tang Xinxin, he drove away directly.

However, Du Cheng did not return to Shuiyuetian Villa directly, but went to the military base.

The first thing he enjoys in all research results is naturally Du Cheng.

He went directly to the base where the plane was manufactured. Ye Zhengtang was already waiting for him in the base.

Today, there are only two planes parked in the entire huge workshop, one of which is Sun and Moon 1.

"Brother Du, this is your Sun and Moon 1. We have helped you modify the power system. This one is the first aircraft produced by our base with life alloy.

Seeing Du Cheng arrive, Ye Zhengtang pointed to the two planes and said to Du Cheng.

During these forty days, Du Cheng not only completed the evolutionary research of the level system, but also invested a lot of energy to finally complete the final research on life alloy.

However, Du Cheng has only one life alloy researched at present, that is, a life alloy mainly based on aviation materials. This alloy has very strong regeneration ability. While ensuring extremely strong toughness, even if it is hit by a bullet in the air, it can use the heat energy generated by the air outlet to heal quickly.

It can be said that this kind of life alloy will greatly enhance the vitality of the aircraft, especially fighter jets. Unless they are hit by missiles or artillery shells, life alloys will have a very terrifying recovery ability.

Coupled with the level system with more than doubled performance and stealth technology, it is very certain that as long as one fighter legion with more than a thousand fighter jets is formed, this fighter jet legion will become a nightmare for all countries.

Du Cheng looked at the alloy plane carefully, and then said, "Thank you for your hard work, the production of this alloy plane should be slower, right?"

"Well, because of the material, it will take at least five days to build an alloy aircraft. However, if we wait for the rest of the military bases to be built, we are sure to build more than five alloy fighters within five days.

Ye Zhengtang responded truthfully, although these are state secrets, for Du Cheng, Ye Zhengtang knew that he did not need to hide anything.

Du Cheng nodded gently and asked, "Well, have you tried the practicality of an alloy aircraft?"

"I've tried it. Even if it's a sniper bullet, the life alloy can be restored within three seconds. Ye Zhengtang responded very surely, but after pausing, he continued: "Brother Du, this life alloy has one disadvantage, that is, after being shot by an electromagnetic laser weapon, the recovery ability of the life alloy will be reduced by more than ten times more than ten times.

"This martial arts knows why this is small and it does not pose a great threat to us. In terms of our power system, unless it is a large laser weapon, ordinary laser weapons will not be able to hit our plane at all.

Du Cheng smiled and continued: "As for large-scale laser weapons, other countries cannot understand them in the past ten years, so we can ignore this shortcoming for the time being, and in ten years, we will have newer technologies to replace them."

As he called Du Cheng, Ye Zhengtang also had a little smile on his face and said, "Brother Du, we will be relieved if you say this."

"Okay, I'll try out the new power system first."

Du Cheng didn't say anything else, because what he wanted to know most at the moment was the new power system that could increase the degree of the aircraft to a level.

Ye Zhengtang arranged the matter in the sky for Du Chengxun. After only a dozen minutes, Du Cheng flew directly to the sky in the plane.

This new aircraft, equipped with a stage power system and using life alloy as the main material, was named Riyue 2 by Du Cheng.

Although it is only No. 2, this plane passed Sun and Moon 1 far away, no matter on either side.

The size of this aircraft is nearly one-third larger than that of Sun and Moon One, and the decoration and space inside are almost extremely luxurious. In comparison, Sun and Moon One seems a bit shabby.

But this doesn't matter. Anyway, he has many private airports, and Riyue No. 1 will only be used as a backup plane at that time. He will ask Ye Zhengtang to help him customize another private plane.

Then there will be three private jets for transportation, which will fully meet the needs of his big family.

The plane flew past the sky quickly, and the new power system was indeed amazing, nearly twice as powerful as the original power. It originally took more than 40 minutes to get from the capital to the city, but now it only takes twenty minutes to be enough.

Moreover, this is still the case where the real staging system is not turned on. If the real staging system is turned on, the itinerary will be further shortened.

Not to mention anything else, just with the current power system, Du Cheng’s time to Paris can be shortened to within two hours.

In this way, if Du Cheng is willing, he can go back and forth between Paris and China at will.

Du Cheng tried the plane very skillfully for a while, and he was very satisfied with the new power system. After all, this new power system and life alloy are one of his many research results in the past month. It is also one of the most important ones.

After trying the plane, Du Cheng quickly landed in the airport. He was not in a hurry to leave. Next, he would stay in the capital for a few days, and then return to the city for a few days. After he was clear about everything in the country, he would fly to Paris and accompany Ai Qier to wait for the arrival of his children.

There is actually a reason why Du Cheng did not rush to leave.

It was Mr. Ye’s birthday tonight. Originally, Ye Chengtu planned to set up a few tables for the old man, but after Mr. Ye’s rejection, he finally decided to get together for a simple meal.

This simple meal did not invite any outsiders, and it was just a family to have a meal.

However, when Du Cheng arrived, the Ye family's enthusiasm today was obviously different. An invisible excitement and excitement seemed to fill everyone's heart. When Du Cheng entered the door, he could even hear Mr. Ye's laughter.

"Old man, uncle, is there any happy event? Why are you all so happy?"

Entering the second and second place, Du Cheng asked Mr. Ye and Ye Chengtu. He knew that Jin Jiao Kewu's happiness and excitement were not because of his birthday, but because of something else.

"That's right, it's a huge happy event. Du Cheng, guess what kind of happy event is going to be."
