Chapter 1999

"In fact, many developed countries are studying these," Li added

"Similar studies have been carried out in China, the United States, even our Eastern neighbors and island countries, and I'm afraid we've all made corresponding ones."

"The reason why we don't show it is that we don't want to let each other know, because once it is made public, we will enter the next earth age."

"If this era comes too early, it will be harmful and powerless for our common people. What's more, there is still a very thorny problem to be solved at this stage."

Chu Yutong and Wu qingmo asked in one voice: "what's the problem?"

"Energy."

Li Xing said faintly: "at this stage, the energy used by all our human instruments is nothing more than oil, electricity and related products."

"It's like nuclear energy, which is very efficient, but we can't use it directly. We can only use it to generate electricity."

"This is actually a very serious waste of nuclear energy."

"It's a pity that we can't reach the technical level now, so we can only do it now."

"Where and what are we going to do now?"

Speaking of this, Li Xing suddenly stopped.

Chu Yutong and Wu qingmo met Li Xing almost at the same time. Li Xing didn't have time to understand the fragrant and soft body of the second daughter. He pinched a formula in his right hand.

Then, from Li Xing's pocket, one yellow Rune paper after another flew out.

Under the control of a very special force, these things even lined up in front of Li Xing.

And the stairs are tilted, going up.

If it wasn't for Li Xing, Chu Yutong and Wu qingmo would never have looked up.

When they looked along the direction of the stairs, they were surprised to find that there was an entrance in the upper corner of the front.

This time, there was no one standing there.

That is to say, so far, Li Xing's men have only detected here.

Li Xing said to the second daughter behind him: "there may be a little danger in the next area. If you are afraid, you should hold my hand."

In fact, Chu Yutong and Wu qingmo are absolutely safe here, otherwise, Li Hang will not bring them.

After all, Li Hang always pays attention to safety in his work and will never advance rashly.

But Chu Yutong and Wu qingmo almost reached out and grasped Li Xing's arm at the same time.

Especially Wu qingmo, this is the best time to approach Li Hang. How could she miss it?

After grasping Li Xing's arm at the same time, the two girls looked at each other. From their eyes, they could see their indomitable spirit.

Li Xing smiles indifferently, and immediately takes her two daughters to step on the Yellow Rune paper floating in the air.

When Li Xing stepped on a piece of Rune paper, it also dazzled with a golden light.

This kind of halo formed a pure golden staircase, people stepped on it, even a little fluttering.

Although this feeling is very dangerous, but with the protection of the luggage, the second daughter obviously does not need to pay attention to these, they pay more attention to the surrounding environment and the entrance in front.

Because they found something standing at the entrance in front of them against the golden light.

From a distance, it looks like a stone statue, but after approaching, I found that it looks very like a person.
