Li Yifan showed his hand. "It's only thousands of years later. About 100 years ago, two people invented the airplane. It's just that they are not Chinese. The plane they invented is similar to Mozi's aircraft in shape, but the principle is different. The first generation of aircraft by adding a propeller, through the high-speed rotation of the propeller, bring a kind of levitation force, and then can fly off the ground. After a hundred years of technological evolution, today's aircraft weigh hundreds of tons, that is to say, it can reach one million jin, and carry more than 500 people in the sky at the same time. If the speed is 4000 Li an hour, the fastest speed can reach 5000 Li an hour. "

"What?"

Several people were surprised, showing an incredible expression, "a million kilograms of weight flying in the sky, can reach a speed of 4000 miles an hour?"

"Well, in fact, it's just the current speed of science and technology. There are also high-speed railways, which are slower than airplanes. You can understand it as a kind of car running on the ground. But it can carry thousands of people at the same time. However, when I left with my ancestors, the earth scientists had already designed an hour of 45000 Li. Of course, it is still in the experimental stage. If it is successful, the speed can be compared with that of xianzun

At this point, Li Yifan pauses again. "In fact, if we give enough time to the earth, with the science and technology of human beings on the earth, we can master controllable nuclear fusion, and then we can create an artificial sun, even xianzun can be destroyed."

"Artificial sun? Controlled fusion? What's that? Can you destroy immortal

Several people looked at each other as if they were listening to the book of heaven.

Li Xuanwu explained to one side, and after listening, several people widened their eyes.

"You mean people on earth are studying to make something similar to the sun?" Zhao Gongming was astonished.

"Yes, the current stage is still in its infancy, but we can control the controllable fusion to 100 seconds. If we can give the earth hundreds of years, with controllable nuclear fusion, they can easily create several artificial suns, and xianzun will fight and detonate them directly, which means that xianzun may not be able to withstand the power of such celestial explosion. For example, the supreme being of the fairyland stands at the top of the fairyland, but it is still subject to the forces and rules of the fairyland. Fairyland is equivalent to a super large earth, and human beings create a more terrible planet than the earth. If it is detonated directly, it will directly produce a black hole, that is, immortal's body will be decomposed in the black hole. "

"Unfortunately, the earth doesn't have so much time to develop. After all, the enemy won't give us so much breathing time."

After hearing this, Zhang Daoling and others felt that the change of the earth is really amazing.

"It seems that although the earth's martial arts are declining, it's not that everything is not going to work," Zhang Daoling said with a sigh of relief. "According to this, if one day the earth succeeds, it will have the ability to protect itself."

Hearing this, Li Yifan knew that they had misunderstood.

"You're wrong. I say so, but artificial solar energy can't succeed. It's all unknown. Who can say exactly what will happen in a few hundred years? Besides, you may not have a concept of the things I described. The black hole formed by the explosion of a star is not a funny thing. Once it appears, it will devour the entire stellar system. How big is the star system? I don't know how big fairyland is, but I'm sure fairyland is the size of two star systems, not necessarily the size of the Milky way. But once a black hole is born, let alone a star system, ten galaxies can be swallowed up in an instant. "

All of a sudden, everyone was quiet.

"The formation of black holes is very strange and completely uncontrollable, and once they are formed, they will become bigger and bigger. That's true, but it's suicidal to burn both the artificial sun and Immortal Jade. So let's honestly think about how to improve our strength. " Li Yifan has no choice but to show his hand.

The crowd was speechless and spent the whole day teasing them.

"White happy," Zhao Gongming rolled his eyes.

"Cough."

Li Yifan cleared his throat and said awkwardly: "it's not to tease you. It's just to remind you that as long as the earth has enough time, it can certainly develop some self-protection capabilities. What's more, I had made a lot of preparations before I left. Sooner or later, they will be able to protect themselves. "

In other words, the pressure of Zhang Daoling and others will not be so great.

After all, the earth is not completely defenceless and is being slaughtered.

People's faces look a little better. It's also true that the stronger the earth is, the more reassuring it is for them.

"Let's talk about these things later. Business matters."

Zhao Gongming returned to his senses and walked seriously into the hall. On the left and right sides of the hall, there were two workbenches. Many people were surrounded in front of them.

Walking over to see, Li Yifan saw a big screen hanging above both sides, with words rolling on it, saying some announcements.

Zhao Gongming went to the front of the stage on the left and chatted with a man in front of the stage who was maintaining the order of the scene.

"It's not brother Zhao an. How can I come here today?" When the man saw Zhao Gongming's face, he was surprised, and immediately his face was full of smiles. He looked more polite.Zhao an is the fake name Zhao Gongming registered here.

"I brought some friends here to register," Zhao Gongming said with a smile, and then waved to a few people in the rear.

"Oh, here are some of you," said the man, who clearly knew Zhang Daoling and Wen Qiong.

As for Ge Hong, Li Xuanwu and Li Yifan, who are all strangers, he doesn't know them.

Zhao Gongming said with a very polite smile, "let me introduce you. This is one of the persons in charge here. In short, it is the receptionist who is responsible for the registration of new people. His full name is Ding Jue. You can call him manager Ding. "

"I've seen Ding in charge." Li Yifan and his three friends saluted each other respectfully.

Ding Jue quickly waved his hand, "what steward, I can't be steward, that's what our deacons are qualified to call."

Although he said so, there was a very useful smile on his face.

Li Yifan looked in his eyes and thought that Zhao Gongming was no wonder that he was able to win over this man. It seemed that he had investigated the details of other people's personalities. This man was obviously a man with a certain vanity but not enough courage.

Such a person, in this fairyland Federation, is definitely not a deacon, but he wants to make some achievements and become a steward.

This person can be used.

In an instant, Li Yifan decided to make use of this person to gain benefits for himself.
