In fact, when he saw the little finger-thick collector, he guessed that he didn't need so many.

But the Demon Soul Clan is really too tough, to the point of being unheard of.

In the past two days, he had tried all kinds of tricks, but in the end, this guy was still able to bear it calmly. He seemed not to be affected by these tortures at all, and he really enjoyed the experience.

Damn it, what the hell?

If the homeless people in Qinggang City were so hard-boned back then, how many times would they have torn down the Qinggang Shelter inside and out so easily?

With this kind of willpower, Hunting Tiger is completely helpless and can only retaliate in this way.

Boom, boom.

After the verification was passed, the locomotive began to make a dull sound from the head, which looked a bit like a steam engine.

However, the two methods of operation are different, and they should use special technology developed by the dwarves.

"What kind of power does this thing use? Why does it feel so retro?"

"It doesn't matter what he does, as long as he can walk."

"How did they build the underground railway? It would be great if we could build one in Qinggang City."

"I heard it was chewed out by monsters, the kind that can eat dirt."

"Really or not, can a monster chew it so well?"

"You're stupid, let the monster chew it out first, and then you can refine it yourself."

""

Yehu was studying how to operate the locomotive in the carriage.

For the subway, which only existed in records, people outside were curiously looking at the internal structure.

Let’s not talk about the difficulty of building this large platform that everyone is on. Just building hundreds of kilometers of culverts more than 30 meters underground is an extremely exaggerated engineering problem.

And based on the information Ji Wuming gave one by one in the past two days.

Naturally, the dwarves do not have large-scale equipment such as shield machines, nor have they developed any super-technical equipment to excavate underground. Instead, they use the simplest method.

They developed a special kind of ground-eating lizard.

This lizard is only eight meters long, but it can eat nearly 500 cubic meters of soil a day, which is enough to carry 30 large garbage trucks.

Based on the calculation that every meter of subway line excavation will produce about 40 cubic meters of earth, a lizard can dig forward 5 meters per day.

At the same time, ground-eating lizards secrete a special mucus after digesting soil.

Once this mucus enters the soil, it will generate cross-sectional tension similar to that of injected concrete, causing the soil to quickly harden, thereby firmly locking the structural stability of the underground culvert.

About three hundred lizards are digging day and night, and the amount of work can reach four kilometers in a day.

In one month, a hundred kilometers of underground railway can be built.

Of course, these are just theoretical data values.

In the actual performance of digging, the ground-eating lizard's ability is even more exaggerated than this data, and it can even digest stones and plant roots.

In addition, the soil sprayed by their saliva will quickly soften. With the construction of the dwarf engineering team, the monthly construction volume can be doubled.

The only drawback is that ground-eating lizards can easily suffer from indigestion if they eat a large amount of soil in a short period of time.

The group of lizards who recently built the Honghua Gang underground railway need to rest for at least a month before they can carry out other engineering tasks.

"From here, it's about two hundred and forty kilometers to the nearest connection point in Black Rock City."

"There are three checkpoints, which are set up at the 110-kilometer border, the 170-kilometer Black Rock City border and the final Black Rock City checkpoint."

Ji Wuming spoke up and introduced.

He has been to the dwarves three times and is no stranger to the route. The only difficulty is the complicated inspections he needs to face during the process.

In the past, when the middle-aged man from the Demon Soul Tribe was with him, the dwarves did not create any difficulties.

But this time he needs to be in front. How to explain the middle-aged man's failure to follow is the key.

"Are all the people at the checkpoint like him?"

Turning his head, Liehu pouted at the place where the middle-aged man had just been taken away.

Ji Wuming was stunned for a moment, then shook his head dumbly.

This guy is really a weirdo. Could it be that he wanted to "persuade" all the way there?

"It's okay, my people will kill them as soon as possible."

"As long as you can stabilize them and don't let them escape immediately or sound the alarm."

A look of murderous intent appeared on Yehu's face, but he quickly took it back.

Speaking of which, if the plan has not been set up, we need to break into the opponent's interior first and plant the bomb, otherwise we can just sit on the subway and kill him all the way.

"Is that so? That's no problem. This is what I'm good at."

Ji Wuming nodded immediately. Since Yehu didn't restrict what methods he could use, there were many ways to operate.
Chapter completed!
