Although Chen Zheng has always known that the hope of returning to Earth is slim, even when this slim hope is shattered, it is really uncomfortable to drink this bitterness.

Chen Zheng probably knew why the drift valve was destroyed.

For a drift valve that can break the void and bring people to another planet, it is inevitable that huge energy will be needed. Although it is difficult for Chen Zheng to estimate the specific amount of energy, he is very clear that if converted into electric energy, it will definitely be an unimaginable number.

What does it mean to send a few people and some things out of thin air to another planet? You should know that even the nearest planet is at least a few dozen light years away! The number of light-years a little further will exceed the triple digits!

Therefore, no matter how high the energy utilization rate of the drift valve is, it will inevitably consume nearly infinite energy.

And the source of energy is certain that only substances such as zero crystal can be supplied stably.

Zero crystals are easy to use and easy to store. The most important thing is... According to the mass-energy equation, if the matter is completely annihilated, the energy it emits is also unimaginable.

Although I don’t know how alien technology uses zero crystals, coincidentally, the zero crystals that turned into energy finally disappeared - it was a complete annihilation, and there was no trace of existence.

So it is certain that the drift valve must contain large pieces of zero crystals.

As a monster that feeds on zero crystals, it is no surprise that it is torn apart from the drift valve to take out zero crystals from the crowd and eat them.

What's more... Maybe it was the zero crystal in the drift valve that attracted the monster.

When Chen Zheng thought this way, what he saw was the big hole on the floor.

There should be the path where the monsters appeared here. Chen Zheng did not rush to explore the cave, and first checked around.

Not to mention, he really made other discoveries - on a corpse with green hair, Chen Zheng found another metal product that was obviously destroyed by external forces. From the outside, it should be an jewelry, with a space roughly the size of a fingernail in the center.

It is not difficult to guess that maybe a piece of zero crystal was buried in the jewelry a long time ago, and maybe this is the cause of green hair's death?

Chen Zheng, who was about to throw away this piece of metal, suddenly stopped again - since it can be used as an ornament, then this metal should be more precious, right?

Thinking of this, Chen Zheng put it away.

Next, Chen Zheng demolished the entire iron house, but unfortunately he had been walking for a long time and found nothing else.

Is this the only one left?

Chen Zheng looked at the big pit, took a deep breath, and slowly leaned over his head...

...It was pitch black inside.

Even if you use tactical flashlights, you can see at most more than ten meters away, and then it becomes pitch black.

However, the information volume of these places that can be seen clearly is still very large.

First of all, the closest place to the ground is a thick floor, which is different from the iron floor that is only 5 cm thick in other places. The iron plate here is more than half a meter thick, and it should be a special alloy.

Chen Zheng cut it with a lightsaber and found that the floor area of ​​a special thickness is not small, and its area is about half of the room, and it is exactly in the center of the room.

Chen Zheng raised his head and looked at the room. The area here was probably a slightly larger bedroom.

Although Chen Zheng thought it was strange before, he thought that aliens might have this habit. But now when he discovered these strange things, the sense of incongruity became even heavier.

The layout of this tin house...

Anyone will find it strange to see it - in this iron building with an area of ​​about two basketball courts, is it really reasonable to place an ordinary bedroom at the end of a passage facing the gate?

Because the iron house is a single-story building, Chen Zheng never thought about this before, but when he demolished the entire iron house, the strange sense of incongruity became even better.

And this thick iron lid also shows that there must be something covered underneath!

Chen Zheng chopped the metal lid with a lightsaber, then moved the metal debris away little by little, and then... a more solid ground appeared in front of Chen Zheng.

The ground here is not ordinary soil, it is obviously formed by artificially. In other words, it seems that it should be made of something very similar to cement.

Fortunately, Chen Zheng has a ready-made cave to observe.

The soil layer is still deeper.

From the hole to the depth of about 5 meters below, there are all such concrete-like things, just as if there was a big pit here and it was firmly encapsulated by the concrete.

Just when Chen Zheng thought it was a whole piece of cement, he suddenly found some reflection of metal - that was when he was cutting the upper layer of metal, and the metal reflection reflected from the break of the lightsaber.

Chen Zheng used a lightsaber to cut some down on the cement floor. After removing the gravel, the metal object also slightly exposed a section - its surface was very smooth, and the exposed one was about ten centimeters long, tilted downward at an angle of about 30 degrees, and the other end was buried deep in the cement.

This is……

Chen Zheng did not dare to draw a conclusion, so he continued to dig carefully.

After he dug more than one meter deep, the metal object finally revealed its full picture - it is a handrail. To be precise, it is a stair handrail!

This makes sense!

No wonder the passage directly opposite the gate leads here: wouldn’t it be reasonable to build a staircase at the end opposite the gate?

So, why do stairs appear in a bungalow?

The answer is self-evident.

The underground of the iron house... is there something! It's really just that something unexpected happened later, and then it closed the place again!

Chen Zheng took the flashlight back to the round pit again and tried his best to shine it down... There was indeed soil under the cement, and it was hard to say deeper places, and it would be difficult to see clearly if it could not go down.

After thinking about it for a while, given that he had been tossing for so long and had made a lot of noise, and there was no reaction under the cave... so Chen Zheng decided to test it further.

He threw down the tactical flashlight.

Then, a piece of light became farther and farther away. A few seconds later, the sound of the flashlight falling to the ground came, and the light below the cave flashed, and then disappeared.

“!?!?”

Chen Zheng suddenly got goosebumps.

Just as the light disappeared, it seemed that some shadow suddenly shrank back into the darkness that could not be shined by the light!!

There is really something underneath this!!!

And this cave is likely to be the passage where the monster came out...

Could it be that...is a nest below!?
