"Rest."

Lu Lin was also tired, but he just let his brother rest well, his eyes fell on his sister's gray body, and he endured the emotions that had been spent all night before coming out again.

Not long after the voice fell, Lu He fell asleep directly.

Xiao Chusheng also sat on the floor, thinking in silence until his gaze fell on a building not far away.

The thing that resembles the top of a tower.

Soon, something seemed to shine in a distant place.

Xiao Chusheng frowned. For a while, he couldn't confirm whether it was reality or his own illusion.

Until Xiao Chengwei took his arm.

"Dad, something is shining over there!"

This sentence attracted the attention of the others, and Xiao Chusheng also confirmed the real existence of light through his son's words.

In the daytime, it can be so eye-catching, and the brightness of the light is unusual.

"I'll take a look, you..."

Before he finished speaking, Xiao Chusheng met Xiao Chengwei's firm expression.

"No, I want to go with Dad!"

If it is really dangerous, it is not safe here.

Think of the body armor on his son and the bracelet with a shield.

Xiao Chusheng agreed, he stood up and walked over with Xiao Chengwei.

"Brother, your father and son were too dangerous in the past."

Lu Lin spoke out in time, trying to stop it.

Because it was kind, Xiao Chusheng's tone was very calm.

"Stay here is to wait for death, I will call out what happens, just run away."

If even Xiao Chusheng with the system overturned his car, then they wouldn't have much effect. If they can run, just run.

As he approached with firm steps, Xiao Chusheng's eyes almost couldn't open, and the light became stronger as he approached.

Xiao Chengwei tugged at the corner of his clothes, and then stuffed something in it.

Looking down, Xiao Chusheng was startled.

It's Brother Qi's sunglasses, where did this kid come from? !

He took it and put it on, and there was no resistance at all because it was a dead thing.

If you want to live in the doomsday, you can't have those ridiculous thoughts.

As they walked to the light, Xiao Chusheng was stunned, looking at what appeared in front of him, how could he not believe it.

It's actually a door!

There are many crystals inlaid on this door, and the energy source of light is these crystals.

As for why a door should be able to shine...

Xiao Chusheng didn't want to understand.

He stepped forward, and with a movement of his mind, the white jade sword appeared in his hand.

After slashing towards this door a few times, unexpectedly, the white jade knife could not destroy it!

Only a few white marks were left.

"Dad, look at this!"

Xiao Chengwei's immature voice sounded, following his fleshy fingers and looking at it, it was a groove.

"This is……"

Many ideas came out, and Xiao Chusheng took out the crystal collected from the mutant tiger in the light and flint, and slowly put it on it.

This piece of crystal coincides perfectly with the groove!

The light diminished in an instant, and the door of invisible material slowly opened, and inside was a passage leading to the underground.

Xiao Chusheng didn't step in hastily, he frowned and looked around.

The appearance of this door was because the spikes caused the ground to collapse a little further, which exposed the deeply buried door.

"Research objects are discarded..."

Xiao Chusheng thought of his son's words, and he understood it all at once.

The ground will collapse, which should be caused by these so-called ‘research objects’, and their source...

It's the door in front of me!

As expected, it should be a laboratory.

In order to hide or destroy these abandoned things, they directly used means to make the ground cover them, but they certainly did not expect that those things not only did not disappear, but also let the laboratory see the sky again!

"How's it going!"

Lu Lin's questioning came from a distance, Xiao Chusheng thought for a while, he turned to look over, and he could see Lu Lin's figure clearly from a distance.

"Don't come here, pay attention to safety."

Xiao Chusheng responded and led his son into the laboratory door.

There was a smell of potion in it, but there was no way to tell what potion it was. It was very strange.

The ground of the laboratory is very clean, obviously completely isolated from the outside world.

As it continued to deepen, Xiao Chusheng bought a light stick to illuminate the gloomy laboratory.

It's strange, why does the door glow, but there is no light source inside?

Xiao Chusheng was puzzled. He looked at the test bench that appeared to his side. It was clean and there was nothing left.

However, this laboratory has not been completed, there is still a long distance, and a door appeared on his left hand.

"Let's go in and see, will you be afraid?"

Seeing his son's face tightened, Xiao Chusheng expressed relief.

Upon hearing this, Xiao Chengwei immediately shook his head and hesitated to say his thoughts.

"I seem to have been here before."

When the voice fell, Xiao Chusheng was struck by lightning.

The amount of information in this sentence was too great, and he slowed it down for a while before adjusting.

"Such words can't be told to others!"

Xiao Chusheng had a faint guess in his heart. Is the special gene in Xiao Chengwei's body... also a synthetic part?

If not, could it be that the gene was extracted and used for experiments?

Thinking of the spikes outside, Xiao Chusheng's face became heavier.

"Dad, are you unhappy?"

Xiao Chengwei seemed a little cautious, and he worried that Xiao Chusheng would be angry because of it.

In exchange, he rubbed his hair with a big hand.

"No, Dad is just thinking about how to hide your secrets."

Xiao Chusheng said, the thoughts in his mind have not been interrupted, he realized that the main task of the system has gradually surfaced.

only……

It's hard to say whether this task is related to Xiao Chengwei's genes or something else.

Reaching out and pushing the door open, many bottles appeared in front of Xiao Chusheng's eyes.

These bottles are of weird shape. The bottles should be smooth, with wavy lines on them, and there is no lid on them, and the mouth is only as wide as a bamboo stick.

"This smell is a bit familiar."

Xiao Chusheng smelled the weird smell in the room, which seemed to have appeared in his memory, but he couldn't remember it clearly.

Seeing everything in the room clearly, Xiao Chusheng took his son to exit and closed the door again.

Going deeper, it is clean, without any leftovers.

"It seems that I left under extremely safe conditions, so I was able to transfer the things in the laboratory."

Xiao Chu came to the conclusion that the father and son left the laboratory, and the crystal was still in the groove.

The white jade knife was picked, the crystal left the groove, the door of the laboratory suddenly closed, and the dazzling light appeared again.

Xiao Chusheng held the crystal in his hand, and the hot touch made him very surprised.

After careful observation for a while, he was shocked to find that the crystal had shrunk a whole circle!

This groove is not only used to open the door, but also absorbs energy.
