My Doomsday Train.

Chapter 66 Now, it’s time for you to be nervous.

Inside the "Star" train.

Chen Mang stood up and walked to the No. 2 special carriage. He consumed 1000 units of copper ore and built a "12.7mm heavy machine gun bullet production line" and a "5.56mm rifle bullet production line" respectively.

With these two production lines, the heavy machine gun on the top of the carriage, which had almost never been fired, was finally no longer just a decoration, but could be put to real use.

It is worth mentioning that——

Each upgrade of the Heavy Machine Gun will only increase its effective range and rate of fire, but will not increase its power.

What really determines the power of a heavy machine gun is the grade of the bullet.

The higher the bullet level, the more powerful it is.

of course.

Heavy machine guns can only use bullets of the same level or lower level than their own, and cannot use bullets of higher level than their own.

For example, a level 3 heavy machine gun can use level 1 bullets or level 3 bullets, but cannot use level 4 bullets.

The green-grade accessory "Three-legged Cat Heavy Machine Gun" is made of iron ore and is also upgraded with iron ore.

After consuming 3000 units of iron ore.
He finally upgraded a heavy machine gun to level 5.

There are currently 8 carriages in the Stellar train. A "three-legged heavy machine gun" is installed on the roof of each of the first four carriages, while the roofs of the last four newly built carriages are still empty.

This thing, like "Armor", needs to be built and upgraded separately. Unlike "Car Blade", once you upgrade, no matter how many carriages you build later, they will come with the same level of Car Blade.

"."

Chen Mang sighed lightly. This thing is also a big resource consumer. But to be honest, it is a green-grade offensive vehicle. The effect of the first super model unlocked is really good.
-
"Tricky Heavy Machine Gun Level 5 Super Model Effect": The heavy machine gun can be linked to the 'Train Assist AI'. As long as the enemy is within the range of the enemy detection radar, the Train Assist AI will start to automatically lock on the enemy, greatly improving the hit rate.

ps: The green grade accessory "Train Assistance AI" needs to be upgraded to the maximum level.
-
He has roughly summed up his experience.

The higher the grade of the accessories, the better the supermodel effect unlocked.

The supermodel effect of "offensive accessories" is greater than that of "functional accessories", and "functional accessories" is greater than that of "life accessories".

For example, this supermodel effect.

Directly force the lock on the head, as long as it is within the radar range, it will be killed in seconds if it shows its head.

There is no need to arrange thugs to control heavy machine guns. Not only is it troublesome, but it is also difficult to improve the hit rate. Now it is directly handed over to the "Train Assisted AI", which greatly improves combat efficiency.

Normally speaking.

The upper limit of green-grade accessories is only level 3, so he has already met that condition. His "Train Assistance AI" is already level 5. After connecting the circuit system of this "three-legged cat heavy machine gun" to the control console, this machine gun was officially upgraded to an AI machine gun.

As for the remaining three machine guns, they will have to be upgraded separately before they can have this super model effect.

After doing all this.

Chen Mangcai looked at the "12.7mm heavy machine gun bullet production line" in front of him. He upgraded it to level 3 in one go, which consumed 1200 units of copper ore. It could not be upgraded to level 5. Upgrading to level 5 required a full 3000 units of copper ore, and he only had 4210 units of copper ore in total.

After reaching level 5, there will be no more copper mines to make bullets.
-
"Level 1 Bullet": 1 unit of copper ore is used to craft 1 bullet.

"Level 2 Bullet": 5 unit of copper ore is used to craft 1 bullet.

"Level 3 Bullet": 10 unit of copper ore is used to craft 1 bullet.
-
“It’s so expensive.”

Chen Mang looked at the price of bullets on the bullet production line, and the corner of his mouth twitched slightly. A level 3 bullet required 10 units of copper ore. Heavy machine guns had a fast firing rate, and two or three hundred bullets were fired in the blink of an eye. If they were all level 3 bullets, that would cost two or three thousand units of copper ore.

What kind of boss should he defeat to make back his money? It should be at least at the level of a man-eating spider. But as for the man-eating spider he met, two or three hundred heavy machine gun bullets might not be enough to kill it.

「子弹生产线」虽然已经升至3级，但并不代表着只能打造3级子弹，从1级到3级子弹都可以打造。他消耗了500单位铜矿打造了共500发1级子弹。

Together with the original reserves, there are now more than 800 level 1 heavy machine gun bullets in the train. This can ensure that the "built-in fire control system" is in a usable state as long as he thinks about it.

The machine guns extending from the ceiling inside each carriage will give all the members in the entire train a thorough cleanup.

Power must be based on force.

This thing may never be used, but it is indispensable. The machine gun with the muzzle facing inward represents his power and status in a sense.

Finally, another 2000 units of copper ore were consumed to create 200 level 3 bullets.

So far——

The resources accumulated in the train over the past few days were almost squandered by him.

Only 8239 units of iron ore and 510 units of copper ore remain.

Chen Mang patted the "heavy machine gun bullet production line" that was like a money-eating beast. At this moment, he finally realized the biggest charm of white-grade vehicle accessories, which was economy.

It can also break the defense of level 3 boss.

"Cutter Blade" only consumes some energy stones.

As for that "heavy machine gun", every bullet was the result of his hard work.

Although the latter is more powerful, has a longer attack range, and even has supermodel effects such as automatic locking, it consumes too many resources and can only be used as a trump card. He is reluctant to use this thing unless it is absolutely necessary.

"Chariot Blade" is still more useful. It doesn't matter if it takes some time. Anyway, his armor is already level 3. Currently, there are basically no monsters in the Tieling Wasteland that can break his defense.

"Tieling Wasteland" is a low-level area.

The highest level train in this area is level 3, and the highest level monster is also level 3, and his "armor" is also level 3.

"Set off."

Chen Mang returned to the train cabin and sat on the control panel. After looking at the still sufficient energy stones, he retracted the Hot Wheels, lowered his mechanical legs, and slowly stepped on the accelerator.

A centipede-like train.

Just before hitting the canyon wall, the mechanical legs climbed up the wall easily and naturally, and quickly climbed up along the ninety-degree wall.

The viewing angle is raised.

One can vaguely see, in the darkness of the night, in the abyss of doom, a train climbing rapidly on the cliffs at a fast speed.

soon.

The train drove out of the cliff, put on its hot wheels again, and roared towards the endless wasteland shrouded in the night.

the goal--

Looking for the tide of zombies that surrounded him several times.

He came back for revenge.

It was you bunch of bastards who disturbed him mining every day, making him nervous every day, afraid that a tide of zombies would sneak up on him at any time.

Now, it's time for you to be nervous.
