Where is this?

Almost at the same time as he boarded the train, Mason collapsed completely to the ground, with blood gushing out of his mouth and nose.

The power of the World Tree is not something that can be easily borne. If the Monster Lord had not wanted to devour him instead of killing him directly, if the fight between Black Mist and the World Tree had been more intense, he might have fainted.

The vest was not in much better condition, with severe wounds all over his body. The red-haired young man stumbled and almost dropped his original body to the ground, so Mason simply lay down on the ground. He controlled Oleus to take off the ring and put it on his original body, and then he fell to the ground in the same position.

He really used the vest as a means of transportation during the whole journey. Apart from the basic control, he did not open even a little sense. Mason carefully strengthened the connection, but was immediately dizzy from the double pain and fatigue. He simply cut off the connection and let the red-haired young man lie on the ground to recover.

Whoever wants to suffer this pain can suffer it, but he won't suffer it.

The boy wiped the blood off his face with difficulty, climbed up with difficulty by grabbing the seat, and staggered and fell on the chair. The World Tree was still working, and the gentle white light enveloped the train, allowing it to move forward in the dark fog.

When Mason got on the train and paid his ticket, he naturally learned the rules of riding the train.

As long as you silently think of where you want to go when you enter the carriage, the Black Mist Train will take you to your destination. What Mason silently thought of was [a place where the Monster Lord cannot find].

The train sped forward in the black fog, and the conductor disappeared. Mason was the only one left in the huge carriage, and the clanging of the tracks made him drowsy. Although there were no tracks in the black fog, the train moved forward steadily as if it knew where it was going.

The power of the pollutant was triggered, and the wounds on the boy's body gradually healed. Especially the hand he had stretched out earlier, the itching and numbness of the flesh growing was like countless insects gnawing at mulberry leaves. Sticky whispers leaked out from the air, tempting humans to mutate. However, after facing the monster master, this sound can be completely ignored.

Unconsciously, the boy slowly closed his eyes. He had a good sleep and replenished his energy. When he woke up, Mason's face was facing the car window. He moved his hand subconsciously, and his palm, which had not yet fully recovered, felt a pain.

The dim light pierced his eyes, and Mason immediately realized that something had changed outside the glass window. Perhaps because he was far away from the Monster Lord, the light of the World Tree had disappeared, revealing the true scenery outside.

The young man opened his eyes wide in shock, not daring to believe what he saw.

Where is this?

At some point, the Black Fog Train actually ran on a metal track. Through the window, one could see the complex traffic environment in the sky. The metal tracks intertwined like viaducts in the sky. Countless Black Fog Trains were running on these tracks, all in an orderly and spectacular manner.

These tracks all lead to a city with tall walls, and the antiquity of the city can be seen only from the cannon holes and moss on the walls. The train carrying him sped towards the city, as if it was its final destination.

Both Oreius and Canaan had seen maps of human territory in the noble associations and churches. Mason searched his mind again and again, but could not find the corresponding city.

Putting aside other things, in the current human territory, except for the Mechanical City, there is no other city that uses mechanical creations on such a large scale. And the Mechanical City is a floating city, which is obviously inconsistent with the appearance of this city.

While I was thinking, the Black Mist Train had already approached the city. Seeing it up close made me feel even more majestic. Heavy cannons were mounted in the muzzles of the city walls. Even though they were covered with traces of time, their power in the past could still be recognized. There were many entrances and exits for trains halfway up the city, and different signs were thoughtfully set up to distinguish the stations. The Black Mist Train slowly drove into the third platform. The dilapidated parking lot was covered with dust, and it looked like no one had been here for a long time.

A long whistle sounded and the car door opened automatically.

The conductor reappeared at the door and said in a hoarse voice, "We have arrived at the final stop. Please get off the bus, two passengers."

...is this the final stop of the Black Fog Train?

Mason had to admit that he was curious. The red-haired young man got up from the ground, stretched his stiff body with a grin, and then got out of the car with the original body.

Just after they stepped out of the car, the conductor also got off the car.

Mason turned around in surprise, only to see that the ticket seller, whose face was blurry, had turned into a smart and capable blond woman wearing a women's shirt and trousers. She met the boy's gaze, smiled politely, and then walked towards the platform.

Behind her, the shabby black train was now brand new. People kept coming out of the train, men and women, young and old. Most of them were wearing long skirts or trousers in dark grey colors, and their overall style was relatively simple. They were carrying luggage or other things in their hands, and talking noisily to each other. The quiet station suddenly became lively and filled with the bustle of people.

"Thank God, we are finally here. My waist is about to break after sitting in the car for so long."

"Let's take the sleeper when we leave. I told you before that hard seats are not suitable for you, Mom."

"A berth? My goodness, that's half a silver coin more! I'd rather die in a carriage than take a berth!"

"I'm already a clerk, I can earn this little money back quickly..."

"My dear friends, we will definitely make a lot of money this time. The goods I bought this time are all good stuff, and the demand will definitely exceed the supply!"

"Dad, this station is so beautiful. Can we take the train back home?"

"Of course, my child, you can ride it as many times as you like."

"......"

Passengers filed out from Mason's side and headed towards the exit. Their attire, language, and currency were all different from what Mason knew. Mason observed for a while and was surprised to find that none of them were bloodline people.

Something was not right. The station in front of him was also different from what he saw in the train compartment. The spacious and bright platform was lit with crystal street lights, and there were route display boards between the pillars. Mason walked over to take a look, and the routes and city distribution were clearly marked on them. Just as he was concentrating on recording the route, someone pulled the corner of his clothes.

"Good afternoon, gentlemen. Is this your first time here?"

The little boy asked cleverly. He was wearing overalls, a newsboy cap, and a bulging cloth bag slung across his shoulder, with a few newspapers faintly visible.

Mason nodded, and the little boy smiled and said, "You've come to the right place. You can find everything you want here. You look like you're here for □□, right? I know where the best weapon shop is. You can buy guns and bullets there. I also know where the best mechanical masters are. They will definitely be happy to modify weapons for you. It only takes five copper coins, and I will tell you everything I know!"

Weapon shop?

Master Mechanic?

Mason's heart moved slightly.

He was able to confirm that the other party was not a bloodline person, and ordinary people would never say such words. Guns were forbidden to them.

But both the little boy and the people around him seemed to be accustomed to this and even proud of it.

"It sounds good. We've heard of this place for a long time. But the place we're from is different from here. The currency is different. We may need to find a pawnshop or money exchange first."

"This is easy. Please follow me."

The little boy took the opportunity to take over the business and led the two people to the exit. The layout of this place was similar to the train station in his previous life. Walking down the stairs, you can see a wide corridor with many entrances and exits on both sides. From time to time, passengers walked out. Mason saw some children dressed similarly to the little boy. It looked like a small industry of considerable scale.

"Of course you have to go to our largest and most fair exchange house to exchange money. Don't worry, I'll lead the way."

The child's voice sounded like singing, and he skillfully led the two of them out of the crowd. He was quick-witted and familiar with the place, so he easily found the passage with the least people.

Oleus followed Mason, his hand on his shoulder in a protective gesture. His clothes were torn and bloodstained. He had handsome features, but his cold eyes were piercing. The boy took one look and immediately looked away, concentrating on trying to please the other young master.

He had good eyesight and could tell that the person who was answering was probably another person. The linen-haired boy smiled at him. Although his clothes were torn, the fabric was fine and the damage was less severe than that of the young man. He wore an expensive and exquisite ring on his right hand, and he was obviously a young master from a certain family.

These are probably the elder and younger brothers, right? The boy thought to himself, this is a big deal!

Led by the boy, they quickly walked out of the passage. The breeze blew on his cheeks, and Mason's eyes suddenly opened up.

The light grey buildings stand tall in the square, presenting a cold and simple architectural style. The white ape flag is hoisted high, and the sky is hazy and rainy. Unlike the tourists in bright clothes, the city residents are easy to identify. They have a serious temperament like soldiers. Even ordinary people carry guns, and the clothes of adults are mostly dark.

The gold, silver and copper coin trading system was only popular in the pre-Black Mist era and the early Black Mist era. Later, due to too many murders and robberies, the noble associations and churches at that time changed the trading system. Currency was made by mixing various metals, and large-scale transactions were circulated in the form of checks. Later, this round currency was named after the scholar who proposed the plan at that time, Rauby, and became the trading system used to this day.

Similarly, guns were also popular among ordinary people during the Black Mist period. It was not until later generations discovered that guns could cause mutations that they were truly banned from circulating among ordinary people.

Mason quickly analyzed the situation and suddenly said, "I'll give you an extra copper coin as a reward. What is the name of this city?"

The boy blinked in confusion: "——"

He seemed to say something, but the sound dissipated before it even passed through his throat, and his mouth movements became blurred in an instant.

All memories were wiped from their minds. The two looked at each other. The boy asked blankly, "Do you have any other instructions? If not, I will take you to the exchange office."

"...Let's go."

Mason had some guesses in his mind, and he kept piecing together the key words in his mind, trying to figure out some clues about this place.

He had to wait for more information to confirm. He temporarily suppressed his thoughts and followed the boy's steps.
