Fang Qianmo and the others only felt the energy fluctuations in front of Li Yu, which was almost comparable to the energy of the Big Bang, of course, this was just their illusion, but Li Yu was not wrong to use his strength to eat.

In a minute, the dimensional space channel was opened, and Li Yu's slightly weak opponent Qianmo said: "The calculation is wrong, the spell is also imperfect, the waste of energy is too great, I'll go first!" ”

After speaking, Li Yu stepped into the dimensional space passage, and then Fang Qianmo and the others saw that Li Yu had advanced some distance in the passage and appeared on the moon. After appearing on the moon, Li Yu closed the dimensional space channel with a wave of his hand.

Fang Qianmo and the others here didn't speak for a long time.

"Li Yu was squeezed dry just now, right? I've never seen Li Yu so weak! Sun Yixuan broke the silence, as if she didn't quite believe what she had just seen.

"Shouldn't be weird, right? If you think about how many light years Li Yu has crossed, and he also said that the estimation is wrong, it is not surprising that the energy consumption is excessive! Lin Wanbai was also a little disbelieving, so the reason for convincing himself was also a bit far-fetched.

For ordinary civilizations, ordinary mages, the span of distance is indeed related to energy, but for laboratories, there is a way to achieve the greatest purpose with the least energy.

Lin Wanbai said that even she couldn't convince herself.

"When Li Yu comes back, let's ask him again, you also heard what he just said, it's because of his own misestimation and the construction of the spell, so the energy consumption is excessive."

What Fang Qianmo said also made sense, so they returned to their respective spaceships and waited for Li Yu's reason. Who knows, this is three days.

So, what did Li Yu do in the past three days?

As soon as Li Yu appeared on the moon, he felt the situation in his body, and then frowned, and said to himself: "The energy in the body is exhausted, this feeling has not been experienced for a long time, but the speed of recovery of this energy is too fast, right?" ”

With the spell just now, Li Yu did squander the energy in his body, not to mention the reason in between, anyway, his feeling was very magical, after he became a mage, the energy in his body was almost empty.

But the novel experience didn't take a few seconds, and the mana in Li Yu's body recovered at an overwhelming speed, and Li Yu wanted to experience that feeling more, but there was no way to do it.

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

"Forget it, let's contact Cheng Yingnan!" After speaking, Li Yu was stunned, he didn't have a communicator, Xiao Wei was not by his side, and there was no communicator in the ring?

At this time, I wanted to contact Cheng Yingnan, and Li Yu was confused for a while, how to contact her?

"Is this a sequelae of mana drain? Without the support of spells, even the movement of her mind has been affected, and I can use spells to inform her! ”

patted his head, Li Yu quickly thought of a way to contact Cheng Yingnan, he just didn't think of it for a while. There is no communicator, and there are spells, as long as Cheng Yingnan is still in the galaxy, he is not afraid that he will not be able to contact her!

Cheng Yingnan was working at the Lunar 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 affairs of the Deep Sea Academy in the Purple Moon Kingdom at this time.

was dealing with things, Li Yu's voice sounded in her ears: "Ying Nan, you are there, give me a signal!" ”

Hallucination? Cheng Yingnan was puzzled, but she knew that it was impossible for Li Yu to appear on the earth at this time when he was at ease in a certain celestial region more than a billion light-years away from the earth.

But Cheng Yingnan also believes that it is impossible for him to hallucinate, and after becoming a mage, it is really difficult to appear in such a thing as hallucination.

So, did Li Yu really appear? "Hurry up! What are you waiting for? The surface of the moon is super cold! ”

Li Yu told a bad joke, would he still feel that the surface of the moon was cold?

It seems that Li Yu did come to the moon, Cheng Yingnan held back the doubts in her heart, gave Li Yu a spell message, and then, Li Yu appeared in front of her.

"Why did you come back alone?" Cheng Yingnan was puzzled.

"Huh! Experimented with a spell and came back! Li Yufeng said lightly, at this time he pretended to be forced, and there was no one on the whole earth who could compare!

"Say what I can understand! Really, people who have been far away are just different! Cheng Yingnan sneered, and then choked Li Yu!

Li Yu knew that Cheng Yingnan was dissatisfied with the task he gave her some time ago, so he didn't say anything and said directly: "Isn't our research on dimensional space channel technology over?" If we build a dimensional space beacon on this side of the earth, we can return to the earth at any time. ”

"I gave you the beacon, and you said that it couldn't be solved for a while, so won't I come back to help you solve the problem?"

Cheng Yingnan sneered again, saying that he didn't believe the reason Li Yu said.

"Hehe, it just so happens that I also want to experiment with the use of spells to build dimensional space channels, so I set the purpose on the earth, isn't this killing two birds with one stone?"

"That's not enough! But Li Yu, you can't always throw me tasks that are beyond my ability, okay? I didn't know anything about the dimensional space technology you were talking about, so you gave me the manufacturing drawings of the space beacon. ”

"You know what? I don't even understand the drawings now, how could that Rausch beacon be built?! ”

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

"It was my mistake! However, the matter of dimensional space beacons is very important, with this thing, no matter where we are in the universe, once something happens on this side of the galaxy, we must rush back as soon as possible! ”

"In that sense, it's a strategic thing, and it's not an exaggeration at all!"

"Forget it, you have a point! Now that you're back, you're responsible for this matter! Cheng Yingnan breathed a sigh of relief, Li Yu took over this matter, which really made her feel less stressed.

Cheng Yingnan didn't know what kind of technology the dimensional space channel technology was, but from the effect they described, she could see its importance. It is precisely because it is so important that Cheng Yingnan was very anxious after receiving Li Yu's task.

Cheng Yingnan was worried that he would not be able to complete the tasks assigned by Li Yu and them, which would affect the arrangement of the laboratory.

If because she didn't complete the task of building the beacon in time, it happened that the earth encountered a problem that she couldn't solve, and Li Yu and the others couldn't return in time, and their responsibility would be great.

Now that Li Yu has taken over, the pressure is suddenly gone.

"There's no problem with this, I've already built the beacon, you can arrange for it to be placed on the moon, and we can return to Earth at any time after it is activated!" Li Yu comforted Cheng Yingnan.

"You've already built it? Yes, that's not a problem for you! ”

"Huh! After the beacon is activated, its next maintenance tasks will have to be handed over to you! But you don't have to worry, the maintenance of beacons is not too troublesome, the most important of which is the replacement of energy and vulnerable parts. ”

"I've made these modular, and it's very easy to replace, just pull them out and plug them in."

Cheng Yingnan looked at Li Yu with deep suspicion, "Is it really that simple?" ”

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

"I believe you!"

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

"Don't blame me! Listen to what you yourself say, this dimensional space channel technology is such a rebellious technology, and the unit of distance spanned is actually in billions of light years. ”

"How can I possibly have the bottom of my mind to maintain this beacon device?"

Well, Li Yu does often ignore one fact. That is, although Cheng Yingnan has officially joined the laboratory, and all the materials of the laboratory are open to her, she is not with herself after all, and it is not easy to learn the knowledge of the laboratory.
