Wearing heavy protective clothing, Song Ziyu followed the team out of the lower city shelter and came to the ground that was in his heart.

However……

It was pitch black all around, so dark that Song Ziyu doubted his life.

This is a bit incredible!

Song Ziyu looked around and then looked at the sky.

Even though he has the ability of night vision, Song Ziyu still cannot capture the sun and moon in the sky.

Not only that!

My eyesight is so poor that I can hardly see the stars.

"how so?"

Song Ziyu couldn't help mumbling to himself.

"What's wrong?"

Xiao Ai asked.

"Where are the sun and moon of your plane?"

Song Ziyu asked curiously.

"What do the sun and the moon look like... I have never seen it." Xiao Ai stroked his half-mechanical head and thought for a while and said: "But judging from the data I have stored in this regard, the sun was born when I was born.

It has been destroyed before! Without the sun, the moon will naturally disappear, because we can see the moon entirely because of the sun."

"Destroy...destroy?"

Song Ziyu had an incredible expression on his face: "Are you kidding me? You can kill the sun? How did you do it? Why?"

Xiao Ai replied: "I don't know the specific means used, but the information retained by my optical brain tells me that in order to contain Sartre's attack, humans at that time thought of destroying the sun to cut off the source of silicon-based life energy.

.”

"So you destroyed the sun? How could you do it?" Song Ziyu couldn't understand at all.

"I don't know...I can't remember."

Xiao Ai held her head and made a painful sound.

"Forget it, let me ask, why should you take it seriously?" Song Ziyu patted Xiao Ai on the shoulder and signaled Xiao Ai to stop thinking.

…

The team was ready to go and groped forward under the cover of night.

Seeing that Xiao Ai's mood was getting better on the road, Song Ziyu asked again: "So, after the sun was destroyed, has the situation become better?"

Xiao Ai shook his head and sighed: "Not really."

"Why?"

Song Ziyu asked: "Didn't you destroy the energy source of these silicon-based life forms? Why haven't you turned defeat into victory?"

Xiao Ai sighed and replied: "Sart found an alternative energy source."

"What energy?" Song Ziyu asked.

"Yes, nuclear energy." Xiao Ai replied: "The core of our planet is also energy... Sartre penetrated the earth's crust and directly grabbed energy from the underground as a supplement... In the end, we failed."

After listening to Xiao Ai's words, Song Ziyu's breathing became very heavy.

Human beings in this world have fought to such an extent, and yet lost in the end. What a despairing realization this is.

With a heavy heart, Song Ziyu followed the team towards the Black Rock Shelter.

Although they couldn't see their fingers in the dark, with the help of the positioning equipment provided by the professor, the team was still able to move in the set direction, and the journey was very easy.

Because in this extremely dark environment, the activity ability of silicon-based life forms is also reduced to a minimum.

After several hours of trekking, there was gradually some light in the sky.

But this kind of light is dim at best, and there is no sign of dawn at all.

Taking advantage of this environment, the team continued on their way. Along the way, they often saw the remains of some buildings and metal machinery destroyed by humans... Fortunately, they arrived at the location of the Black Rock Shelter without any danger.

…

This is a naturally formed rock mountain, and the majestic rock mountain has become the best hiding place.

Thick rock formations can well isolate silicon-based life forms from scanning heat sources, allowing them to survive.

"The Black Rock Shelter has almost penetrated this rocky mountain. There is no reason for Sartre to discover it!"

Xiao Zhao looked at the huge mountain in front of him and couldn't help but said.

"Don't be in a daze, take out the detector and check if there are any monsters around." Lao Zhao explained.

So several team members took out their instruments and began scanning around the rocky mountain.

After confirming that there were no silicon-based life forms around, Old Zhao walked to a blasted rock layer and began to look inside.

A huge gap appeared in the blasted rock formation, and it must have been from here that the silicon-based life forms entered the black rock shelter, and then drove out all the humans living here.

"Who's going to take the lead?"

Lao Zhao looked at the black hole and asked.

No one answered. In this situation, everyone knows that being a vanguard will not end well. If anything happens, the vanguard will be the first to die.

So no one rushes to die.

What a joke!

No one knows what happened in the Black Rock Shelter. Who knows if there may be danger inside?

Then Lao Zhao looked at Song Ziyu.

"Mr. Song, please!"

Lao Zhao made an inviting gesture.

Song Ziyu glared at Lao Zhao, then sneered, and then got into the dark cave.

The other team members behind him were about to follow, but Lao Zhao stopped them directly.

"What are you doing in there?"

Lao Zhao asked.

"Captain? What do you mean?"

The team members were a little dumbfounded.

Old Zhao said coldly: "Let's wait until Mr. Song confirms the safety before we go in."

"Oh!" All the team members thought thoughtfully after hearing this.

But Lao Zhao’s heart is very clear!

Others may not be able to perceive it, but it is impossible for you to perceive it wrong... There is a Satyr (silicon-based life form) hidden in this cave!

This satyr is very cunning!

It can fool the inspection instruments, but it cannot fool Lao Zhao's perception.

The reason why Lao Zhao asked Song Ziyu to take the first step was entirely out of selfish motives.

Before Song Ziyu appeared, Lao Zhao had an aloof status in Xiacheng Refuge and was a well-received existence.

It’s different now!

Lao Zhao felt threatened!

This is a challenge to one's own status.

Therefore, Lao Zhao really wants to take this opportunity to get rid of Song Ziyu!

certainly!

Doing things like killing yourself is very risky and unwise.

Killing someone with a borrowed knife is the most cost-effective business.

Now, Lao Zhao is waiting for Song Ziyu to go in and die...

After about a few minutes, the sound of metal collision came from the Black Rock Shelter.

The sound was very short, and Lao Zhao knew that he had succeeded!

"Everyone be prepared, there is danger in the cave!"

Lao Zhao greeted and took out the firearm from his waist.

When the team members saw the captain acting like this, they were all shocked and nervous. At the same time, everyone also speculated that Song Ziyu was doomed.

However!

Just when I was extremely nervous!

The sound of footsteps came from the dark cave.

Accompanying the footsteps was a light humming sound.
Chapter completed!
