"Whatever it was meant to be for, what the ancients built is now a nuisance to us."

"As far as I know, there is an ancient self-destruct mechanism within the metal above and around the passage."

Klein crouched on the ground, his fingers gesturing over the drawings he had drawn.

"This self-destruct mechanism isn't something tall and tall, but it's reliable and effective enough."

"They're bombs inside metal walls, connected to a self-healing detonation button."

"When the button is pressed, the bomb inside the wall will be detonated, and the giant metal fragments that have peeled off itself are enough to block the passage, but what is worse is that there is a second circle of bombs inside the wall, and the effect of this circle of bombs is similar to that of a hot melt gun."

"First the metal fragments peel off, and then the torrent of molten metal pours into every crevice, turning these metal fragments into a single piece, blocking the 900-kilometer-long passage."

"The Emperor is above, I can't imagine what the person who designed this thought at the time."

With that, Crane picked up the drawings and handed them to Anrida.

"You know a lot about the self-destruct mechanics of this tunnel?" Qin Mo asked in surprise.

"Of course, my family is the oldest family of engineers on the planet." Klein had an unconcealed pride on his face, "The story of my family's origins is all related to these self-destruct mechanisms. ”

"About 1,700 years ago, my ancestors undertook a secret project set up by the Governor at the time, and it took thirty years to remove a molten bomb from the wall."

"At that time, a war broke out in the Tyrone Nest, and the rebel peer star defense forces organized by an unknown sect fought fiercely."

"Just when everyone thought that the governor at the time would use the bomb for military purposes, he used the bomb to blow up the area where another noble family was located, turning a large number of buildings into molten iron."

After listening to the story told by Crane, Qin Mo sighed with emotion: "It seems that this is also a skill that the governor has passed down from generation to generation. ”

"Their family's skills have been passed down for generations are not just playing with bombs." Klein said.

The three of them stood together and stared at the obstacles in the passage.

When the small talk was over, Qin Mo raised his hand and tried to see if he could use his ability to quickly get through here.

And Klein didn't have hope for this, after all, he was there when Qin Mo built the fortress, and the outer walls of the fortress were all attached to it piece by piece, and compared to the obstacles that blocked the entire passage, the fortress was like a small house.

But you have to try everything.

After Qin Mo concentrated on mobilizing the power of the Star God, the metal in front of the three of them began to flow, flowing down the slope like a liquid, and then it was controlled by Qin Mo to attach to the walls around the passage.

The massive walls of solidified metal fragments are rapidly recovering.

At this time, Qin Mo recalled what Mimic had said, and realized that his strength was indeed gradually recovering.

If you don't dig this giant passage and build a fortress, it only takes a second for the fortress to rise from the ground.

Half an hour later, Qin Mo gave up: "A drop in the bucket, I feel like I'm trying to fill the ocean with stones." ”

An Ruida didn't know what the ocean was, but Crane knew, so he could understand the meaning of Qin Mo's words.

"Are all these obstacles tightly knit inside?" Qin Mo had a whim, "If you can enter the inside of the obstacle and put a hot melt bomb in the gap......

As he spoke, Qin Mo walked towards the obstacle and twisted the laws of physics in a large area around his body, allowing the metal to be penetrated like air.

Crane and Anruida watched Qin Mo penetrate the wall and enter inside, and they were already surprised.

After waiting for ten minutes, Qin Mo turned back and explained the situation to the two: "The inside was filled with molten iron, and it was incurable." ”

"What if we don't dig it?" "Would it be like you go into the metal, let other people walk around you, and then get a piece into the metal and dig a big hole every kilometre for rest?" Klein asked. ”

"You don't think I'm as available as he is, do you? How do you get in without me? Qin Mo pointed at An Ruida.

"That's ...... too," Klein couldn't help it.

Qin Mo began to ponder the way to dig up the passage.

In fact, it is very simple, it is to build construction machinery to excavate, study small construction machinery and high-efficiency metal excavation devices to dig, or build giant construction machinery equipped with energy beams to melt through the metal blocking the channel little by little.

But when he was just thinking about what kind of construction machinery to make, Qin Mo suddenly had another idea.

Since in the future it is necessary to create a way of interstellar navigation that is not based on subspace, then why not start working on it now?

Start with the relevant technologies, make some basic things, and then expand the entire tech tree and become proficient in using it.

Qin Mo himself didn't know what this kind of technology would be, but he felt that this passage was like the distance between galaxies, and there was always a way to cross it.

Qin Mo looked at Klein, "Not only will I not dig this blocked passage, but I will also strengthen it so that it cannot be broken through and destroyed." ”

"We're going to stay in the nest forever?" Klein suddenly felt bad.

"No, we can still get in and out, but we don't need to go through this passage." Qin Mo walked towards the train, "Others, don't waste time on this passage, if the various regiments can't find rebels who can attack, then conduct training and exercises." ”

……

After returning to the fortress, Qin Mo decided to conduct a long study, and before that he had to settle everything.

If, as the mimicry says, there is a larger conspiracy on this planet that is being corrupted, then it is necessary to be prepared to live in the nest for a long time, rather than everyone leaving the nest and never returning.

The establishment of the city of New Cato is imminent.

Qin Mo instructed the master control intelligence to drive the logistics machinery to build a new city, which was to be built like a fortress, and ensure that electricity and water could be connected to every corner of the city, and there were a large number of arsenals and batteries.

Civilians will live under the various artillery batteries in the city, and they will be workers in the arsenal in normal times, and they will operate the batteries as a family unit to participate in the defense in wartime.

There will be a shelter in the center of the city, which will be a refuge for children in wartime, but in normal times it will be a school.

Sports art will not be taught in schools because these are too extravagant and students will only learn how to tell who the enemy is and how to fight the enemy.

Qin Mo wouldn't have delusional hopes of building a utopian city, but he would ensure that the people in the city would easily get what they would have paid for, which was food and fresh water.

After arranging everything, Qin Mo devoted himself to research, and he quickly thought about the direction in which he should conduct research.

That is to create a shortcut that can be traversed in alternating spaces and dimensions—a human version of space necromancy phase transfer technology.
