Lin Feng opened his eyes. He looked around, but did not find anyone beside him.

“Lin Feng, you are finally awake. I thought you would never wake up again.”

The one who spoke was Longbetham. Its voice appeared directly in Lin Feng’s mind.

“How long was I asleep?”

“It has been three days.”

“So, we’ve been in this ruin for more than three days?”

Longbetham did not answer, but Lin Feng knew very well that after three days, even Sage Kang and Sage Yuanyi had probably lost hope in them.

He did not know if anything had happened to Griman, Fu Lin, and Dardan. However, even if something had happened, there was nothing Lin Feng could do. He could barely protect himself now.

Lin Feng checked his mental power. The Mental Power Sphere in his mind had undergone self-recovery during the three days. In fact, he had already recovered a certain amount of mental power and did not feel dizzy anymore.

As for the injuries on his body, the undying characteristic was really miraculous. After three days, all the injuries on his body had recovered. There wasn’t even a scar. It was as if he had never experienced that intense battle at all.

“I wonder if the lizards outside have left. If I go out now, will I encounter the lizards again?”

Lin Feng still wanted to go out. If he could take over the control room, the mission would be complete.

“Lin Feng, do not even think about leaving. This ruin must be a research institute, and the defense mechanism of the research institute has already been activated. Those biomodified beasts are actually the defense mechanism. They will not disappear before killing all the invaders. Once you leave this place, no one can guarantee that you would be still that lucky.”

“Then what should I do? Am I trapped here until I die?”

Hearing Longbetham words, Lin Feng was also a little anxious. He couldn’t possibly hide here forever, right? He was a Metamorphic Realm martial artist, and could actually survive without food for a month or two.

However, if this went on for too long, he would not be able to hold out either. He might even starve to death.

It would be a rare occasion indeed for a Metamorphic Realm martial artist to starve to death.

“Lin Feng, have you never thought of undergoing a second life transition and defeating those lizards? Although those lizards are biomodified beasts, they are just for show. Once you undergo the second life transition and master the combat body, forget about those three lizards, even 30 of them will not be enough of a match for you.”

Longbetham tone was filled with disdain. In fact, neither those biomodified beasts nor the demons of this world impressed Longbetham. Even the combat power of Sages was nothing in Longbetham’s eyes.

This was because be it demons, biomodified beasts, or Sages, none of them had cultivated the combat body!

“A second life transition? I’d like to, but it’s too difficult. I don’t even have a clue now.”

Lin Feng thought for a moment. Actually, it wasn’t that he had no clue at all. Previously, when he was on the verge of death, he had discovered the mysteries of the human body. They were simply profound. If he could continue to study the mysteries of the human body, there was a high chance that he could undergo a second life transition.

However, while a life transition might still be manageable, cultivating the combat body required a huge amount of energy.

“Longbetham, didn’t you say that cultivating a combat body through life transition requires a huge amount of energy? I’m trapped here now. Where can I find energy?”

Lin Feng remembered very well that, as Longbetham had said on multiple occasions, condensing the combat body required massive energy. It was definitely not a small amount. Even if Lin Feng used 20,000 merit value to purchase energy, it might not be enough.

It was already very difficult to obtain a large amount of energy outside, let alone when he was still trapped in this ruin.

“Who said that you cannot obtain energy here? Take a closer look at what this place is.”

Longbetham’s words surprised Lin Feng. He slowly stood up and looked around carefully for the first time.

Initially, he thought that this was just a small hut. However, on closer inspection, he realized that he was gravely mistaken. This was not a small hut at all. It was practically a huge “factory”.

Yes, it was a factory, and a “factory building”.

The space was incomparably huge. Looking up, it was at least hundreds of meters tall, or even taller. There were scattered lights on the ceiling, like the night sky, and a few huge pipes connecting them.

Below were some complicated equipment, as well as some production lines and the like.

Ding.

Suddenly, a sparkling crystal seemed to have fallen from the pipe. It was transported to a small hut by the conveyor belt and piled up.

“What is this place?”

This was the first time Lin Feng had seen a place like this. There was clearly no one, but it was still operating.

“This is a production line for energy modules, or rather, an energy factory. To put it simply, the researchers of the seventh civilization converted the star power in the sky into substantial energy modules before storing them. This conversion system should operate automatically, and the energy consumed is also replenished by the energy modules. Therefore, in theory, as long as the conversion system is not damaged, this system can keep operating.”

“You mean that a lot of energy might have been accumulated in this energy factory?”

Lin Feng understood somewhat now.

“That is right. There are many warehouses there. You can take a look.”

Lin Feng followed Longbetham’s instructions and opened a warehouse. It was sparkling everywhere inside. It turned out that it was already filled with a large amount of energy modules.

Then, there was the second warehouse, the third warehouse, and the fourth warehouse. Without exception, all of them were full.

The energy modules currently converted were piled up in the fifth warehouse, and more than half of the warehouse had already been filled.

“How miraculous. They can actually convert star power into physical energy modules. It’s just incredible.”

Lin Feng was very surprised. Currently, human technology did not have much research on Astral Power. It was only seen as a miraculous power that could be absorbed, transformed, and cultivated continuously by Metamorphic Realm martial artists.

But in reality, in terms of utilization rate, the current human civilization was far inferior to the seventh civilization.

“There is nothing incredible about it. This is the correct way to use star power. Your so-called martial artists in the present are actually cultivating star power. It is simply ridiculous. Even the Astral Power in the body of your Divine Realm martial artists is only equivalent to dozens or hundreds of energy modules. How much can that be worth?”

Lin Feng was silent for a while before asking, “What’s the use of these energy modules?”

“They are very useful. For example, for this seventh civilization, all their terrifying weapons required large amounts of energy modules to operate. Also, spaceships need energy modules too. More importantly, their biomodified beasts, be it rats you encountered previously or lizards you encountered later, all of them actually need energy modules to support their movements. Do you understand now? The so-called Astral Power is actually just a form of energy!”

Looking at the mountain of energy modules in front of him, and then at the conversion system and production line that were still automatically converting the energy modules, Lin Feng’s heart was already in turmoil.
