Fang Qianmo and the others only felt the energy fluctuations in front of Li Yu, almost comparable to the energy of the Big Bang. Of course, this was just their illusion, but Li Yu was not wrong with using his energy to suck.

It took one minute and the dimensional space channel was opened. Li Yu was a little weak and said, "I guess it's wrong. There are also imperfections in the spells. The energy wasted too much, so I'll go there first!"

After saying that, Li Yu stepped into the dimensional space channel, and then Fang Qianmo and the others saw Li Yu moving a distance in the channel and appear on the moon. After appearing on the moon, Li Yu waved his hand and closed the dimensional space channel.

Fang Qianmo and the others here haven't spoken for a long time.

"Is Li Yu exhausted just now? I have never seen Li Yu so weak!" Sun Yixuan broke the silence, as if she didn't believe her eyes very much about what she saw just now.

"It shouldn't be very strange, right? Think about how many light years Li Yu has crossed, and he also said that he was wrong, so it's not strange that it would be too much energy consumption!" Lin Wanbai was also a little disbelief, so the reason to convince himself was a bit far-fetched.

For ordinary civilizations and ordinary mages, the leap of distance is indeed related to energy, but for laboratories, there are ways to use the smallest energy to achieve the greatest goal.

The reason Lin Wanbai said was impossible to convince her herself.

"When Li Yu comes back, let's ask him again. You have heard what he said just now. It's because he has made a mistake in his estimate and the construction of the spell is also problematic, so the energy consumption is too much."

What Fang Qianmo said made sense, so they returned to their respective spacecraft and waited for Li Yu's cause to come. Who knew that this wait would take three days.

So, what has Li Yu been doing in these three days?

As soon as Li Yu appeared on the moon, he felt the situation in his body, then frowned and said to himself: "The energy in his body has been consumed. I haven't experienced this feeling for a long time. But, the energy recovery speed is too fast, right?"

In the spell just now, Li Yu did squander all the energy in his body. Not to mention the reasons in the middle, his feeling was very magical. After he became a mage, the energy in his body was almost gone.

However, in just a few seconds the novel experience, the magic power in Li Yu's body recovered at a rush of speed. Li Yu wanted to experience that feeling more, but he couldn't do it.

Next time, it will not be easy for Li Yu to consume all the mana in his body again.

"Forget it, let's contact Cheng Yingnan!" After saying that, Li Yu was stunned. He didn't take a communicator, and Xiao Wei was not around. He didn't seem to have a communicator in the ring.

At this time, if you want to contact Cheng Yingnan, Li Yu was confused for a moment. How should you contact her?

"Is this a sequelae of mana consumption? Without spell support, even the movement of thinking has been affected. I can use spells to notify her!"

After patting his head, Li Yu quickly thought of a way to contact Cheng Yingnan. He just didn't expect it for a while. There was no communicator and spells. As long as Cheng Yingnan is still in the Milky Way, he is not afraid of not being able to contact her!

Cheng Yingnan is working at the Moon Deep Sea Base. If it weren't for the dimensional space beacon that Li Yu sent back some time ago, she would still be dealing with the Deep Sea Academy in the Purple Moon Kingdom.

While dealing with the matter, Li Yu's voice rang in her ears: "Yingnan, you are there, give me a signal!"

Illusion? Cheng Yingnan was puzzled. She knew that Li Yu was unable to appear on Earth when he was studying in a certain area of ​​heaven more than one billion light years away from the earth.

But Cheng Yingnan also believed that it was impossible for him to have hallucinations. After becoming a mage, it was really difficult to have hallucinations like this.

Then, it was Li Yu who really appeared? "Hurry up! What are you hesitating about? The surface of the moon is super cold!"

Li Yu said a cold joke. Will he still feel the surface of the moon cold?

It seems that Li Yu has indeed come to the moon. Cheng Yingnan suppressed the doubts in his heart and gave Li Yu a spell message. Then, Li Yu appeared in front of her.

"Why are you back alone?" Cheng Yingnan was extremely puzzled.

"Haha! I tried a spell and then came back!" Li Yufeng said lightly. At this time, he pretended to be so arrogant that no one on the entire earth could compare!

"Say what I can understand! It's really different for people who have traveled far away!" Cheng Yingnan sneered, then choked Li Yu!

Li Yu knew that Cheng Yingnan was expressing dissatisfaction with the task he gave her some time ago, so he didn't talk much and said directly: "Hasn't our research on dimensional space channel technology come to an end? If we build a dimensional space beacon on the earth, we can return to the earth at any time."

"I gave you a beacon, and you said that I can't solve it for a while. Am I here to come back to help you solve the problem?"

Cheng Yingnan sneered again, expressing that he did not believe what Li Yu said.

"Haha, I also want to experiment with using spells to build dimensional space channels, so I set my goal on Earth. Isn't this killing two birds with one stone?"

"That's all right! But Li Yu, you can't always throw tasks beyond my ability to me, okay? I don't know anything about the dimensional space technology you mentioned, so you gave me the manufacturing drawings of the space beacon."

"Do you know? I don't even understand the drawings now. How could I create the Luo Shizi beacon?!"

When Cheng Yingnan said this, she was full of resentment!

"This is my mistake! However, the dimensional space beacon is very important. With this thing, no matter where we are in the universe, we must come back as soon as possible when things happen to the Milky Way!"

"In this sense, it's a strategic thing, not an exaggeration!"

"Forget it, you're right! Since you're back, you'll be responsible for this matter!" Cheng Yingnan breathed a sigh of relief. Li Yu took over this matter, which really put her under pressure.

Cheng Yingnan doesn’t know what kind of technology is the dimensional space channel technology, but she can see its importance from the effects described by Li Yu and the others. It is precisely because it is very important that Cheng Yingnan was very anxious after receiving Li Yu’s task.

Cheng Yingnan was worried that the task assigned by Li Yu and the others would affect the laboratory's arrangements.

If she had not completed the task of building a beacon, and the earth happened to encounter a problem that she could not solve, and Li Yu and the others could not return in time, their responsibilities would be great.

Now that Li Yu takes over, the pressure is gone.

"There is no problem with this. I have already built the beacon. Just ask someone to arrange it and place it on the moon. After it is activated, we can return to Earth at any time!" Li Yu comforted Cheng Yingnan.

"You've made it? That's right, for you, that's not the same thing!"

"Haha! After the beacon is started, the next maintenance task must be handed over to you! But you don't have to worry. Maintenance of beacon is not a problem. The most important thing is the replacement of energy and the replacement of vulnerable parts."

"I made all these modular, and it's extremely easy to replace them. Just pull them out and plug them in."

Cheng Yingnan looked at Li Yu with deep doubts, "It's really that simple?"

Li Yu said helplessly: "It's indeed so simple!"

"I believe you!"

Li Yu Jiji had no choice but to take out the beacon and demonstrate the maintenance project to Cheng Yingnan on the spot. The suspicion in Cheng Xiangnan's eyes dissipated!

"It's not my fault! Listen to what you said, this dimensional space channel technology is such a terrestrial technology. The units of distances that cross actually range in units of billions of light years."

"How could I have a clear mind to maintain this beacon equipment?"

Well, Li Yu often ignores a fact. Although Cheng Yingnan has officially joined the laboratory and all the laboratory information is open to her, she is not with her after all, and it is not easy to learn laboratory knowledge.
