My Doomsday Train.

Chapter 218 "This tunnel shouldn't have existed before the apocalypse, right?"

No whistle.

There was no DJ playing either.

Although he was in a very agitated mood, Chen Mang still chose to walk into the darkness in front of him as gently as possible, quietly and stealthily.

After all, he only has level 10 armor.

You can roam freely in the "Zombie Basin", but when you arrive at the blue area "Crisis Valley", you still have to be careful, keep a low profile, and upgrade to level 12 armor as quickly as possible.

Then I started to be high-profile in both my life and my work.

It was night time.

The sky full of twinkling stars above the Crisis Valley is quite attractive.

Stars are really magical things. They can evoke the most primitive desires in the human mind, just like seeing a beautiful girl in disheveled clothes. You want to pounce on her without thinking, but you can't reach out and touch her.

The moment he passed through the light curtain—

"bang"

A tiny cracking sound was heard outside the train, and then the Star Train officially entered the "Crisis Valley" area. The "Information Detection Radar" and "Enemy Search Radar" that had been operating all the time quickly displayed lines of information on the control panel screen after entering the area.

There is a level 9 monster nearby being chased by another level 10 monster.

More than 1 meters further away, there is a level 10 train guarding a level 2 iron mine and mining.

In addition, there are some scattered low-level monsters.

The highest-level mine in the area is a level 8000 iron ore located 3 meters underground.

everything is normal.

"call"

Chen Mang breathed a sigh of relief. The screen showed that the armor level of the level 10 train was level 8. Just as he expected, although his level 10 armor was not very able to withstand the monsters in this area, it would definitely have no problem withstanding the train.

It is difficult for these trains to solve the problem of high attack and low defense.

Theoretically speaking.

The best defense is attack. As long as the attack is strong enough, the enemy will be annihilated before they can get close. Then what's the point of defense? For example, his "Black Hole Armed Robot" has no armor defense, but it still works well. But this is only in theory.

There will always be a time when close combat is necessary.

At this time, the "Travel Frog" train controlled by Erdan had said goodbye to him, switched to the rabbit cloud wheels, disappeared into the horizon in the blink of an eye, and continued to complete his exploration mission.

Chen Mang didn't make any noise.

Instead, he extended the drill and headed straight for the Level 8000 iron mine 3 meters underground. He would dig some ore first, and then check if there was any information on the "train radio".

After one hour.

The Star train has stopped in a cave 8000 meters underground. Chen Mang, sitting in a chair, looked at the news on the "train radio" and nodded thoughtfully. Within this hour, he has almost figured out the situation in this area.

Blue area, crisis valley.

A total of four regions intersect.

There are two blue areas and two green areas.

If you want to go to a more advanced area, you need to pass through the two blue areas. There is no direct route, so you need to take a detour.

The reason why this area is called the Crisis Valley is that in the center of this area, there is a large canyon that spans the entire area. It is 8000 meters deep and hundreds of meters wide.

Divide the entire area into two.

To reach the other half of the area, you must have a Bunny Cloud to fly over. In the "Crisis Valley", there is a special monster called "Night Rabbit", which only lives in the wild. After killing this monster, there is a small chance that the Bunny Cloud accessory blueprint will be dropped.

In the other half of the canyon, there are the ruins of a mechanical city. Many train conductors have found many opportunities there. It is said that the ruins of the mechanical city are very large. The tallest building is several thousand meters high. Standing on the roof, you can overlook the sea of ​​clouds.

"Like this."

Chen Mang rubbed his temples lightly and thought that the sense of crisis in this area was smaller, much smaller than that in "Kunlun Mountain" and the "Zombie Basin" after the outbreak. It was similar to the Shahe Plain, and everyone got along relatively harmoniously.

Generally speaking, only areas that meet the following two conditions can get along harmoniously.

1. There are fewer monsters.

Second, there are abundant resources.

There are quite a few resources in this area, so it is an area where trains can develop safely.

"That's good."

He smiled and stretched. It was late at night and he felt a little tired.

It’s good to develop peacefully, he likes to develop peacefully.

The train conductors here like to call the half of the area with the ruins of the "Mechanical City" the "Red Zone". It is a joke that big reds are easy to appear in the Mechanical City. However, after so much time has passed, it has been searched almost completely.

Because of the Night Rabbit, almost one-third of the trains in this area can fly.

The other trains that cannot fly are not because they do not have bunny cloud wheels, but because they do not have enough tail nozzle accessories and cannot reach the minimum take-off speed.

The area where he was located, where the city before the apocalypse had long been reduced to ruins, was called the "White Zone" by people.

Basically, all the supplies that could be collected and the survivors' belongings had been swept away, and the place was basically empty.

There are only more than 40 units of iron ore in the train now.

First, mine this level 3 iron mine, and then look for higher-level iron mines.

This area is huge.

The largest area he had ever encountered was the white area "Tieling Wasteland", which was about two or three times larger than the Tieling Wasteland.

Then he looked at the accessories that could be crafted after upgrading the train to level 10.

There are three in total.
-
"Star Ring Energy Shield": A red-grade accessory that requires 50000 units of iron ore to craft.

Comet Cannon: A red-grade accessory that requires 50000 iron ore to craft.

"Hell Wheel": A red-grade accessory that requires 50000 units of iron ore to craft.
-
Three red-grade accessories!
These three accessories are the core of the train upgraded to level 10. The combat power of a train with these three accessories and a train without these three accessories can be said to be a world of difference!

The grades of vehicle accessories, from low to high, are:

White, green, yellow, blue, purple, red, gold, pink, and colorful.

Above purple is red.

Purple grade accessories can only be upgraded to level 10 at most and have two super model effects.

Red-grade accessories can be upgraded to level 20 at most and have three supermodel effects.

But there is a resource issue involved here.

This is equivalent to the "Chaebol Energy Shield" that was previously built at great expense being useless, and the "Star Ring Energy Shield" needs to be upgraded again from scratch, which will waste a lot of resources. This is why some trains use all their resources to upgrade the trains and do not upgrade the energy shield at all.

As long as there is no danger.

Upgrading first, upgrading to level 10 in one go, and directly upgrading the "Star Ring Energy Shield" is the most resource-saving method.

Of course, the prerequisite is that you can survive to level 10.

The Comet Cannon, however, requires a certain amount of space in the train compartment. Its bore alone is a full two meters thick, and its base is five meters wide. This massive energy cannon, typically mounted at the locomotive's front, requires a locomotive at least seven meters wide. This means that without the capacity expansion feature gained by upgrading to Level 2, this cannon simply cannot be built.

"."

Chen Mang thought to himself that it seemed that the Star Train also had to be expanded. As the train was upgraded, it was an inevitable trend for the train to become larger. After all, the more powerful the weapon, the larger its size. The train was too small and the weapons could not be installed at all.

Even if it is installed forcibly.

It's also a small horse pulling a big cart, which looks out of place.

Although trains cannot reach many places in this way, this is the task that individual ground troops need to perform.

He didn't make any of these three accessories because they were too expensive and he couldn't afford them for the time being.

And that
"Flaming Wheel".

Like Hot Wheels, it is a type of wheel used for traveling on hard, flat ground such as wastelands. It is extremely fast, but it is a high-end substitute for Hot Wheels. It is faster and, of course, more expensive.

That's all the information we have about this area and the Level 10 trains.

It can be said.

Only after upgrading the train to level 10 did I feel like I truly owned the Doomsday Train. Many accessories and functions had just begun to be unlocked. Before that, it felt a bit like a novice village.

With each subsequent level, combat power will be a qualitative leap.

After 12 hours.

Its daybreak.

This level 3 iron mine deep underground has also been fully mined, replenishing the train with another 280 million units of iron ore.

All residents returned to their respective seats in the carriage and began to rest.

The Star Train was shuttling quickly underground, searching for possible iron ore on the surface and underground. There were no monsters underground in this area, at least he hadn't seen any in the 12 hours he had stayed there, nor had he seen any other trains underground, as if no one had the drill accessory.

He was moving fast enough underground, not much slower than on the ground.

Prioritize upgrading armor.

At least upgrade the armor to level 11 first, and then prepare to start adjusting the carriage. There are a lot of residents, so they all need to be crammed into the resident door quickly, and then upgrade all the basic accessories.

Chen Mang controlled the train and went deep underground.

Ever since the incident in the "Zombie Basin", he has now come to a new area. The first thing he does is to see if there is anything hidden underground and drill as deep as possible.

next moment--

When it was 1 meters deep underground, the search radar suddenly started beeping.

It shows that it is 30,000 meters underground.

Own a train tunnel?

It is similar to the supersonic train tunnel in the "Ground Core Nuclear Bomb" area map, except that it is parallel to the ground deep underground, and the tunnel is extremely large, with a height and width of about 100 meters.

With such a large space, not to mention the train, even the largest zombie he encountered, the "Level 7 Mechanical Zombie King", could pass through smoothly.

"Are you really hiding something?"

Chen Mang's face looked a little strange, and he immediately controlled the train to go deeper, ready to see what the tunnel was like. It would be difficult for an ordinary train to detect this tunnel.

First of all, if the drill level is not high enough, the speed of driving underground is very slow, and it will take a long time to get here. Secondly, the range of the search radar is not as large as his. At present, he has not seen what the high-level alternative accessories of the "search radar" are. Normally, the detection range of a fully upgraded search radar is only 3000 meters.

All the way deep.

The drill bit hit the tunnel shell made of reinforced concrete, which was extremely hard and difficult to drill. Even his level 50 drill bit had a hard time drilling. Only bursts of powder floated out, and it had no effect at all.

But he never believed it.

After consuming 37.75 units of iron ore, he directly upgraded the drill to level 100!

The drill bit became harder and ran faster.

Compared with before, it has been greatly improved

When the 100-level drill bit began to rotate rapidly, a large amount of powder floated in the air, and a small hole soon appeared on the surface of the tunnel below. Not long after, a large hole was drilled out, and the train successfully entered the train tunnel below.

The Star train flew in the air in the tunnel, and all 15 carriages landed smoothly on the ground.

The tunnel has four marked roads, commonly known as four lanes, but each lane is wider.

The air in the tunnel was very stuffy and there was almost no oxygen at all.

Both sides of the tunnel walls are covered with a large number of incandescent lamps, making the tunnel appear less dim. You can't see the end in front or behind, and you have no idea where this train tunnel will lead to or where it starts.

"This tunnel shouldn't have existed before the apocalypse, right?"

Chen Mang sat in the train cabin and looked around. "So this train tunnel should be considered part of the ruins of the mechanical city in the 'Red Zone'?"

"It's a secret passage in a mechanical city."

"Even without the Bunny Cloud Wheel, can we successfully enter the ruins of that mechanical city?"

"if it is like this"

He glanced down at the direction indicator on the control panel screen. "If we keep driving north, we should reach the ruins of the mechanical city. But where does this train tunnel lead from here?"

"."

After thinking for a while, he immediately turned the train around in the tunnel and headed south along the "train tunnel"!
He was not very curious about the Mechanical City. Many people had already been there, and even if he went there, he didn't think he could get anything good.

But this train tunnel must have not been visited for a long time, as it was covered with a thick layer of dust. He was even more curious about where this tunnel led to the mechanical city!
No one has ever been to that place.

A place no one has been to means he can eat better!
Inside the train tunnel.

The Star train strictly abides by traffic regulations and runs on the rightmost side of the four-lane road. There is a smaller road on both sides of the four-lane road, and there are signs reminding smaller trains not to occupy the passage of large trains.

Although I know that no one is enforcing the law anymore.

But he still strictly abided by it.

After all, in this damn place, it's not hard to understand that a level 12 robot traffic policeman from a mechanical civilization might jump out from the corner at the next moment, stop his train and give him a ticket.

The train is not going very fast.

He kept the speed at 280km/h. If he went any faster, he would not be able to see clearly whether there was any hidden information on both sides of the tunnel. Some information cannot be judged by AI and can only be judged by the human brain.

The way AI judges information is actually a bit similar to finding differences, and it is difficult to enter into deep association.

Humans can associate the veins on a leaf with a simple drawing, a curvy figure, a woman's butt, and a cigarette afterwards, until they reach the state of sainthood.

AI can only associate botany with a leaf.

From this perspective, they are not on the same level.

This is why AI will never be able to figure out the truth by looking at an apple.

at this time--

"what?"

Chen Mang looked at the scene before him and was slightly stunned: "Is law enforcement so brutal?"
