On Sunday, Li Xiang got the first opportunity to go out after the polar night. The time was from 9 am to 9 pm, and there was a special car pick-up service for the polar night.

In the enviable look of a group of trainees, a group of people who were qualified to go out boarded a heavy truck. Before getting on the truck, they first stated the address of the place they were going to, and then they were **** with their hands and blindfolded. Threw it into the container.

At first, Li Xiang was also worried about conflicts with Kuangtie outside, and then this worry was quickly dispelled. After they were sent to the place, they got off the truck alone, and the destination, etc., would be kept strictly confidential.

Jiye is still in city 0127, but it is far from the city he is familiar with. The address Roka gave is in a medium-sized city called Heicheng.

Heicheng is located on the border of city 0127 and at the junction of city 0126, and city 0126 is a famous unmanaged city, where all kinds of monsters, ghosts and snakes gather.

Heicheng is in such a special area, and naturally there are many black areas.

Li Xiang took off his blindfold. The scale of the city in front of him was huge. The outer city was still an old tall mixed city wall. There were towering defensive towers at four corners. Under the pedestal, the city walls were filled with roaring steam turbines. .

The basic layout of the city is a typical three-in-one model. The top floor is a delicate building that relies on steam-powered suspension. It is generally the residence of the largest power manager in the city or the most important commercial center. It looks like a metropolis. The middle floor The layout ranges from simple to messy. The middle class to the populace in the city all live in this area. There are skyscrapers that Li Xiang can occasionally see in Houcheng, and there are small bungalows that only exist in civilian areas. It is covered with huge, dense pipelines like a spider web.

The lowest level is the underground level that few ordinary people go to.

In addition to urban sewers and other infrastructures, this area is divided into a huge area. Black markets, gambling areas, and underground boxing fields that are not publicly recognized by the military gather here. Dead people are not uncommon, and bodies will be lost at any time. Into the foul-smelling sewer.

In this area, the danger is greatest, and the benefits are the greatest. Compared with the upper world where the class is solidified, the underground world is full of dreams, blood and hormones.

This is the first time I have seen Li Xiang in this chaotic city. It is completely different from Houcheng, which is used for residential and commercial purposes. The whole city is like a behemoth spouting smoke.

After paying the entrance fee of 20 Blue Star coins, he received a temporary pass from the guards. This certificate can only last for one day. After this period, he stays in the city. Once found, he will be arrested and marched. Ministry of prison.

As soon as he walked into the black city, Li Xiang was still shocked. This is the real steam city in his mind. There are carriages and black-smoky steam locomotives on the streets, and people walking in various costumes.

He clutched his windbreaker tightly, paid ten Blue Star coins from an underground passage according to the instructions on the note, and formally entered the underground world of Heicheng.

The slightly cool wind blows through the mouth and nose, with the peculiar smell of decay underground, which is disgusting. Entering this area, the atmosphere changed abruptly. The surrounding people looked tense. They kept a distance of about one meter from each other. They walked on the high corridor, next to the dark underground waterway.

"Hey, brother, come to have fun, just one hundred blue star coins, to keep you from being immortal." The exposed girl standing on the street called out in a southern accent, and also dressed up as an adventurer. Of men will try to pull the pedestrians to the casino and spend a lot of money, as long as they pull a guest, they can get a considerable marketing money.

Li Xiang stopped to observe for a moment, and then continued to walk forward. To be honest, the strange atmosphere of the underground world has an indescribable appeal to young people of their age. Young people like to try some new things, and here can be satisfied. All their wishes, as long as they have enough Blue Star Coins.

It's a pity that he had watched too much in his previous life, and at this moment, he was just an expression of appreciation, and he headed for the note that said "No.123 Black Street".

Black Street is a very famous long street in the underground world. No one who can do business in this chaotic area for a long time is easy to mess with.

Walking into this street, it changes from a noisy moment to a quiet moment.

Most of the people walking on the street were dressed in black cloaks, and they couldn't even see their faces. Seeing Li Xiang walking on the road so unscrupulously, they all cast strange glances.

No. 123 Black Street is a small shop. There are many mechanical devices hanging outside to let people know that it is a shop selling machinery. He knocked on the door and a hoarse voice came from inside. After receiving the promise, Li wanted to push the door and enter. .

"Cough, cough, cough..." The smoke and dust on his face made him almost choked to death. After finally adjusting to the scene in front of him, he was almost splashed into his eyes by flashing sparks.

An old man in a shabby coat sitting in front of a metal operating table was crackling and polishing with various novel tools, smoke and sparks gushing out of his hands.

"Come on? Just sit down and wait for me to finish this cartridge case." The old man didn't look back, still busy with his work.

Li Xiang was shocked. Isn't this old man the one who gave him the invitation code in Wanghai City?

The other party stopped talking. He could only find a small bench to sit on. The whole house was quite large, but it was messy, full of various semi-finished products and mechanical parts. The only thing that could be seen was that the old man made all Weapons such as firearms.

"Oh, it failed." After some polishing, the old man threw a hot bullet to Li Xiang. He caught it and almost threw it out. "There are currently two styles of mechanical firearms, one It is a common air column type, which ejects a high-damage steam column to attack the enemy; the other is an old bullet type that is almost extinct. Do you know the difference between the two and why the latter will be eliminated by the times ?"

"Uh..." Li Xiang couldn't answer. He played with the bullet in his hand, just touching it, and his source quality rose from 0.1% to 0.2%. With the use and savings these days, he probably understood this. The principle of ability.

It extracts the source quality of the mechanical device itself, because the magic particles exist in the air and can also be attached to various objects without any influence or effect on it. The ability to extract is the source attached to the mechanical device. Liquefy it by nature.

In other words, the mechanical device that is more compatible with magic particles can provide him with a high amount of liquefied source material. Now, as long as it is a kind of mechanical device, it is fine.

"Stupid!" The old man smiled and explained, "Why don't you think with your head because you have such a good talent?"

"The latter was eliminated because of the cost of bullets?" Li wanted to touch his head.

"Can they not afford this money?! Tsk tsk tsk, you fixed the steam lamp that day, I thought you were very smart. The reason is so simple that I don’t know, use your mind to think about it, whether it’s a steam gun or The source quality gun is basically a problem of different driving forces. The air column fired by the source quality drive is powerful, but it consumes high and requires high requirements for the user, and ordinary people cannot support such use. And the bullet gun is used Bullets, other structures can refer to the source quality gun, the problem is that the bullet, the bullet manufacturing process has been lost!" The old man laughed a few times, "Understood?"

"So that's the case." Li wanted to nod. "Teached, the master is making bullet cases here. Could it be that he made bullets..."

"Count you clever!" The old man got up, took off his dirty coat, and lighted a steam device at the counter. "Hurry up and make me a cup of coffee."

"Oh..." Li wanted to go to the counter and fiddle with the steam device. It was probably made by the old man. The assembly marks are serious, but it is very convenient to use. Seeing him, he can operate it skillfully. Raised his eyebrows lightly.

"My name is Laogui, and I will be your firearms teacher from now on. Don’t look at me. I’m not a white teacher. From now on, you will come to help me see the store in the morning and learn things in the afternoon, starting from the basic principles of firearms, to production, assembly, etc Wait, as for the question you just asked, you will know it later. Don’t think I’m telling you about your mantle or anything. I just owe a favor to Roca, and your talent will be lost, so I agreed. ."

"Oh, what's your coffee brewing thing?" The old ghost coughed a few times, rummaged through the box and took out a set of dirty apprentice uniforms and gave him, "Let’s learn from making coffee. Just look at it. Like me, a poor man! If you want to get into a noble lady, this is a compulsory subject!"

He drank Li Xiang’s coffee and completed the apprenticeship ceremony simply. Li Xiang was still a little confused, but his instinct told him that this old ghost had a real level, and he slowly discovered himself when he was taking a mechanical class at the extreme night. I prefer firearms courses. It seems that the hobby of the past life will not fade even if I die once.

The old ghost is indeed level, but his mouth is also very smelly.

In the extreme night, Li Xiang, who was regarded as a genius by Roca and other culture teachers, was devalued here. The old ghost always used his own comparisons from the past. The original high-coldness collapsed instantly, and he was alive and well. .

Soon Li Xiang found out why Roca would let him learn new knowledge here. What this old ghost taught him was all prohibited techniques!

What is banned technology? It is a technology that has been explicitly prohibited from private research by the military. If you are caught, you will go directly to prison, and seriously, you will be killed directly!

He was terrified and full of interest at the same time. The old ghost's lectures are different. He does not stick to the teaching materials, but extends them based on the teaching materials. It is a gospel to Li Xiang, who is extremely capable of thinking.

Some of his fantastic ideas can also be verified from the old ghost, although most of them are ridiculed as unbearable content.

The old and the young were arguing fiercely in the shop, and the sky outside gradually dimmed.

Time flies, and when Li wanted to come back to his senses, he realized that it was already half past eight. The course on this day was very tense. The old ghost almost didn't care about the forced irrigation of his strength, but fortunately he had a strong understanding.

After bidding farewell to the old ghost, Li wanted to walk in the dark, feeling a brand new door appeared in front of him.
