Lin Feng opened his eyes, he looked around, but he didn't find anyone around.

"Lin Feng, you finally woke up, I thought you would never wake up again after this sleep. ”

It was Lombettan who spoke, and its voice appeared directly in Lin Feng's mind.

"How long did I sleep?"

"It's been three days. ”

"So, it's been more than three days since we've been in this ruin?"

Long Betan didn't answer, but Lin Feng knew very well that in three days, I was afraid that even the Kang Saint and the Yuan Yi Saint would not have hope for them.

It is not known if anything happened to the three of Griman, Fu Lin and Dardan. But even if something happens, Lin Feng is helpless, he is now unable to protect himself.

Lin Feng checked his spiritual power, the ball of spiritual power in his mind, after three days, automatically recovered, in fact, he had recovered a certain amount of spiritual power, so that his head would not be dizzy.

There are also injuries in the body, the immortal nature is really amazing, three days have passed, all the injuries in the body have recovered, there is not even a single scar, it looks as if it has not experienced that fierce battle at all.

"I don't know if the lizards outside have left, and if I go out now, will I encounter lizards again?"

Lin Feng was still thinking about going out, if he could master the control room, then the task would be completed.

"Lin Feng, don't think about going out. This ruin must be a research institute, and the defense mechanism of the research institute has been activated, and those cyborg beasts are actually defense mechanisms, and they will not disappear until they have killed all the invaders. Once you're out of here, there's no guarantee that you'll be so lucky. ”

"So what should I do, do you stay stuck here?"

Lin Feng listened to Long Betan's words, and he was also a little anxious, it was impossible to hide here all the time. Although he is a Mortal Realm martial artist, even if he doesn't eat for a month or two, he can actually bear it.

But if he can't hold on for a long time, he may be starved to death.

A Mortal Realm martial artist was starved to death, which was really very rare.

"Lin Feng, haven't you thought about the second life leap and defeating those lizards? Although those lizards are biochemical beasts, they are just appearances, once you make the second life leap and cultivate into a battle body, not to mention those three lizards, even thirty is not enough for you to kill. ”

Lombettan's tone was full of disdain. In fact, whether it is those biochemical beasts or the demons of this world, Lombetan doesn't think much of it, even if it is the combat power of the sage, it is not in the eyes of Lombettan.

Because whether it is a demon or a biochemical beast, or a sage, none of them have cultivated into a battle body!

"Second life leap? I want to, too, but it's so difficult that I don't even have a clue right now. ”

Lin Feng thought about it, in fact, he was not completely clueless, when he was between life and death before, he discovered the mysteries in the human body, which were simply broad and profound, if he could continue to study the mysteries in the human body, it was very promising for a second life leap.

But life leap is better to say, cultivating a battle body requires a huge amount of energy.

"Lombettan, didn't you say that life leap cultivation requires a huge amount of energy? I'm trapped here now, where can I find energy?"

Lin Feng knew very well that Long Betan had said more than once that a huge amount of energy was needed to condense the battle body, and it was definitely not a half-star, even if Lin Feng used 20,000 merit points to buy energy, it might not be enough.

It would be difficult to get a lot of energy outside, not to mention that he was still trapped in this ruin.

"Who says you can't get energy here?

Long Betan's words surprised Lin Feng a little, and he slowly stood up and carefully looked around for the first time.

Originally, he thought it was just a small room, but now that he looked closely, he realized that he was very wrong. This is a small house, it is simply a huge "factory".

Yes, it's a factory, and it's a "factory".

The space is incomparably huge, looking up, it is at least hundreds of meters high, or even higher, with stars on it, like the night sky, and several huge pipes are connected.

Here's some complex instrumentation, and then there's some production lines and things like that.

"Ding".

Suddenly, a shiny spar seemed to fall from the pipe, and it was transported by the conveyor belt to a small room and piled up.

"What is this place?"

It was the first time Lin Feng had seen such a place, it was clear that there was no one left, but it was still running.

"This is an energy block production line, or energy factory. To put it simply, the researchers of the seventh civilization transformed the power of the stars in the sky to form a substantial energy block. Then it is stored again, and the conversion system is supposed to run automatically, and the energy consumed is also replenished by the energy block. So, theoretically, as long as the conversion system is not damaged, the system can always function. ”

"You mean this energy factory, it's likely that it's accumulated a lot of energy?"

Lin Feng somewhat understood.

"Yes, there are many warehouses there, you can go and check them out. ”

Lin Feng followed Long Betan's instructions and opened a warehouse inside. There was a lot of sparkling inside, and it turned out to be a large number of energy blocks.

Then there was the second, the third, the fourth, all of them without exception.

The energy blocks that have been converted are now piled up in the fifth warehouse, and more than half of them have been piled up.

"It's amazing, it's amazing how they were able to transform the power of the stars into a substantial block of energy. ”

Lin Feng was very surprised, at present, human science and technology basically did not have any research on star power, it was just a magical power that could be absorbed and transformed by a Mortal Realm martial artist and continue to cultivate.

But in fact, in terms of utilization, the current human civilization is far inferior to the seventh civilization.

"It's nothing incredible, this is the correct way to use the power of the stars, your so-called martial artists now, actually cultivating the stars, it's ridiculous, even if it is your God Realm martial artist, the star power in the body is equivalent to dozens or hundreds of energy blocks, what is it?"

Lin Feng was silent for a while and asked, "What's the use of these energy blocks?"

"It's very useful, let's just say that this seventh civilization, their various terrible weapons, all need a large number of energy blocks to support. There are also spaceships, which also need energy blocks, and more importantly, their biochemical beasts, the rats you met before, and the lizards you met later, actually need energy blocks to support their actions. I see, the so-called star power is actually just a kind of energy!"

Looking at the mountains of energy blocks in front of him, and then looking at the conversion system and production line that were still automatically converting energy blocks, Lin Feng had already set off a storm in his heart.
