I'm trapped in a cube

Lao Xu’s reasons are irrefutable.

On one side is the alien shell man who has been harassing Oasis City, and on the other side is the Wishing Fountain that may create a huge crisis for Oasis City. No matter what, the beneficiaries will be humans.

"Don't worry, if an accident occurs, I will terminate the operation immediately." Lao Xu said confidently.

Then he walked forward and came to the front of the shell people, as if he had become the leader of the shell people.

"Brothers, follow me!"

After walking through the winding waterway, the shell team quickly found a crack leading to the artificial waterway in Oasis City. Lao Xu led the shell people and poured in.

"This way!"

Lao Xu quickly determined the current location, and after twisting and turning in the sewer, he came to a cave entrance closed with a large iron door.

"After exiting this cave, you can reach Oasis City Park."

A shell man stepped forward and grabbed the rusty door lock. The shells covered his hand and crushed the door lock in an instant.

Li Luo asked in a low voice: "Why are the sewers in Oasis City so wide? And there are special exits?"

"This is the original air defense facility. In the past, there were many dangerous creatures in the air in Oasis City. They would frequently attack Oasis City. Later, after the development of Oasis City, the number gradually decreased."

Lao Xu touched the wall and said with some nostalgia, "This place was originally designed to be used as an air raid shelter. Later, due to urban development, it was transformed into an artificial waterway."

It turns out there is such a history.

Just as he was talking, the shell man had already opened the door. It was night outside. Old Xu looked at the sky and said to the shell man behind him: "Wait a little longer."

No one has passed by the entrance of this park for a long time. It seems that because of the previous earthquake, no one had the intention to wander in the park.

After waiting for a period of time, Lao Xu gave the instructions to the shell people: "It's time to attack. Don't disperse when you get outside, just follow me!"

He sneaked out of the cave with the shell people.

As expected of an old man from Oasis City, the path Lao Xu chose was particularly hidden.

First, he walked through the trees in the park from outside the cave entrance, then from the trees to the garbage station near the core area, walked through the alley behind the garbage station, and finally stood in front of the alley next to the square.

Along the way, you can still see the traces of damage left by previous earthquakes. Many facilities have been damaged and have not had time to be repaired.

"There is no surveillance on this stretch of road." Lao Xu suddenly said to Li and Luo.

"How do you know?" Li Luo was a little surprised.

Lao Xu was silent for a moment and said without any concealment: "I wanted to blow up the fountain before and then bypass the surveillance and hide back home, but I haven't put it into practice yet."

It turns out that this is indeed something he can do.

Old Xu stood at the entrance of the alley and observed for a long time, and then said to the shell man behind him: "There is the square in front of you, spread out, and use the shell dome to seal the entire square!"

The shell people heard the order and rushed to the square obediently.

"Are there no guards in the square?" Looking at the empty square, Li Xiangyi asked in confusion: "No one is guarding the fountain?"

Lao Xu nodded: "It's just an ordinary square, how can there be any guards? The fountain is not erupting now, it is just an ordinary pool of water."

He pointed to the facilities in the square that were damaged by the earthquake and said: "We have just experienced an earthquake, so guards should have been sent to guard the high walls on the outside."

"The three teams should be in charge of the city. When a natural disaster occurs in Oasis City, they will be responsible for maintaining the facilities in the city. They don't have time to come here now."

"The people responsible for guarding the fountain during the wishing event are the soldiers directly under the official government. They are not responsible for guarding at ordinary times. There are not many of them and they will not hang out outside now."

"Not to mention other detachments..."

Lao Xu seemed to have a very clear understanding of the guard arrangements in Oasis City.

"You also know this because you want to blow up the fountain?" Li Luo asked.

"Don't talk about blowing up the fountain. That's called 'destroy'. Destroying relics that may have unknown consequences is one of the responsibilities of the investigation team." Old Xu began to correct Li Luo's wording again.

So Li Luo changed his words and asked: "Is it because of 'destroying' the fountain that you learned about the movements of so many guards?"

"That's right." Lao Xu admitted directly without any embarrassment.

He looked at the scattered shell people and said to the two of them: "Hurry in before they seal the square."

After saying that, he walked towards the fountain, and the two of them quickly followed.

The Shell Man was very efficient, and a shell wall quickly rose up around the square, and it continued to grow thicker and harder.

"Don't leave any weak spots!"

Lao Xu walked around and checked whether there were any defects in the shell walls in each place.

The man who once tried his best to break the dome is now the one who makes the dome.

At that time, the dome was to block the humans in the square, but now it is to block the humans outside the square.

"After building the outer perimeter, seal the top as soon as possible. The anomalies here will soon attract the attention of outsiders!" Lao Xu kept urging, and the shell man also worked hard to make shells.

They tried their best, using their hands and feet, to stick to the shell wall and keep spreading the shells.

Lao Xu knocked on the wall that was getting thicker and harder, and murmured: "It's much harder than the wall that sealed us back then."

After the foundation at the bottom of the shell wall was established, the roots of the wall continued to penetrate into the ground, and the top began to curve and extend toward the center of the square.

These shell people were urged by Lao Xu to speed up, and the dome was closing quickly.

"Work harder and don't cut corners on the top! The top must also be made equally thick to prevent outsiders from breaking through from weak points."

At this moment, Lao Xu was like a real shell leader, filled with righteous indignation against outsiders.

If he didn't know the inside story, Mo Ling would really think that Lao Xu was a shell "hero" who was leading his compatriots to do something earth-shattering.

Unfortunately this is all just a deception.

Soon, the dome was completely closed, but Lao Xu did not let the shell people stop, but asked them to continue to strengthen.

"It's not enough! If it gets harder, the underground will have to be completely sealed. Outsiders will have a way to enter from underground!"

He even walked around in a circle carefully, as if he was using his ability to feel for the weak points of the wall.

"Very good! Leave a few people to continue to strengthen, and the others will follow me to destroy the fountain."

Lao Xu shouted again, leading the people in the shell to rush towards the fountain.

"Let's fix this spring together and block all the rock cracks with shells!"

Lao Xu knew this fountain very well.

This is a geyser.

Geysers are formed because high-temperature underground water vapor rises to the ground through rock cracks and begins to condense into water as the temperature drops.

After accumulating for a certain period of time, the geyser will erupt, so there is regularity.

Sealing the rock cracks is equivalent to cutting off the spring water from the source.

Lao Xu wanted to eliminate the root cause.
