In the space, the flashing blue light was an object set at the top of the space, similar to a light. It seemed that because an object fell, it had some effect on the things here, causing the luminous object to flash.
However, considering that no life was found in this ruin, and after such a long time, the object could still emit light, it meant that this object was either connected to a power source or it had its own high-tech battery.
Regardless of what it was, whether it was a power source or a battery, Lu Heng thought that if he could get these things and bring them to the apocalypse, it would definitely solve the city's energy problems.
This way, with the stagnation of technological production in the apocalypse, the energy problems in various places might be solved, and permanently solved.
Thinking of this, Lu Heng urged the vines to lift him to a blue luminous object.
Lu Heng did not directly touch the objects here with his hands, as he did not know the voltage of this thing and whether it would leak electricity.
Controlling the vines to grasp the blue luminous object and pulling hard, the object was detached from the building by the vines.
Indeed, there were no power lines set up by human engineering behind it; this luminous object was independent.
From this perspective, this bit of energy should not be able to supply the city's electricity.
After putting the disassembled object into Lu Heng's spatial city, Lu Heng landed back on the ground.
After a circle, Lu Heng left this underground space. This should have been an underground station. Lu Heng did not explore further, as the oxygen tank on his back could not support him for too long.
Thinking of this, Lu Heng took out a glass jar to collect the gas on this planet and then put it back into his space, planning to find a device to test the elemental composition of the planet's gas later.
After wandering on the surface world for a while longer, Lu Heng found that the things he had moved and taken away before had also disappeared in the real world.
Therefore, things here were not like in that ancient alternate world, where they could be taken endlessly. Things here could not be replicated; taking one away meant one less item in this world.
Unknowingly, time slowly passed. Lu Heng looked at the oxygen level in his oxygen tank, which could still support him to wander here for about an hour more.
However, Lu Heng had no intention of continuing to explore. This world had been destroyed, and the ground was covered with various huge obstacles.
Relying on Lu Heng to walk by himself, and wearing such clothes as a spacesuit, he was slightly clumsy.
Back in the spatial city, Lu Heng took off his heavy spacesuit.
He looked at the still flashing blue luminous object, but Lu Heng could not find any removable interfaces and did not know how to dismantle this thing.
Then he looked at the jar containing the gas from that world and began to search for a device in the space that could detect gas composition.
However, the city where he originally lived was too small. After thinking several times in his mind, only a small device capable of detecting formaldehyde appeared before him.
It seemed he still had to go to a big city to check, but before that, he could catch a mouse or something similar to try.
Exiting the space, Lu Heng returned to the city he had previously cleared of zombies.
There would definitely be mice and the like here, but those little things only lived in dark places like sewers.
Lu Heng released the giant rat, Little Six. This fellow could dig holes and was a metal-element magic beast.
At this moment, its body was covered with a thin layer of metal armor, the style of which was very similar to fish scales covering it layer by layer.
This metal, though seemingly ordinary, was the special metal that Lu Heng had created before. The thin layer could both resist attacks and not hinder movement.
"Go down and catch some mice. Don't kill them, just keep them breathing. Of course, healthy and lively ones are even better."
Little Six nodded, then quickly dug through the ground, searching below the city.
Before long, Little Six returned the same way. It leaped onto the ground, dragging a string of metal balls behind it.
Inside the metal balls, the chirping of mice was incessant, making one's scalp tingle.
"Master, I caught a nest and brought them all back. If it's not enough, I'll go find more." Little Six, like presenting a treasure, scurried to Lu Heng's feet, the metal balls behind it making a harsh dragging sound on the ground.
Fortunately, the zombies here had already been cleared. Otherwise, Little Six's actions would definitely have attracted a wave of zombies. It seemed that the animals from that alternate world still hadn't realized the need to remain quiet at all times in the apocalypse.
"Good, I'll reward Lu Bai with a bath later."
Lu Bai, who was sleeping on a soft blanket in the space, suddenly woke up and sneezed.
"Who's thinking of me?"
After returning Little Six to the space, Lu Heng took out a transparent sealed box and placed two of the mice from the metal balls into the box.
The little mice looked very lively. These mice were also mutated breeds, but their lifespan was not long, so their level did not increase quickly.
Lu Heng blocked the only hole on the box and released the gas he brought back into the transparent sealed box.
Soon, the mice, which were still lively and scurrying around, began to weaken, but they did not die.
Two mice lay in the box, their abdomens still heaving, and their limbs occasionally twitching.
"Is this going to kill them or is it okay?"
Lu Heng observed the condition of the mice, feeling a bit uncertain.
After waiting for a while longer, the mice seemed to have adapted. They stood up again, but still felt a bit weak and were not as lively as before.
"It seems that this gas still has problems, or rather, it makes creatures from Blue Star uncomfortable."
Forget it, it's better to bring all of these to the researchers in the base for them to study. He couldn't open that luminous object for now. Of course, if he opened it violently, Lu Heng estimated he could do it, but the contents inside might be damaged.
Carrying these things, Lu Heng returned to Wuming City.
He handed over his experimental mice and the luminous object to the scientific researchers, and Lu Heng returned to his residence in the inner city.
"Master, look, my level has increased, and I've also gained a new skill."
Sensing Lu Heng's return to Wuming City, the director, whom Lu Heng had asked Lin Yu to bring back, began to excitedly report to Lu Heng within their communication range before even seeing him.
"Oh? Let me see what level you are."
When he finally saw the director's figure, Lu Heng saw the director he hadn't seen in a long time.
The director's level had also increased again after Lu Heng absorbed the crystals of the mutated crocodile and the high-level zombies. This was also the only way to verify what level Lu Heng's abilities had reached after absorbing the crystals.
Level fifteen. The director had now reached level fifteen.
