My Doomsday Train

When the slaves had moved all the iron and copper ore mined today to carriage No. 3, Chen Mang looked at the train panel.

17739 units of iron ore and 1120 units of copper ore.

The once empty freight carriage finally became a little richer again. He hadn't used the "Level 2 Copper Ore Refresh Coupon" yet, and planned to use it after mining this Level 1 copper ore at the bottom of the Doomsday Abyss.

This copper mine was a small Level 1 mine. Before the iron ore was completely mined, this copper ore had to be mined first.

After having resources.

He immediately spent 500 units of iron ore to create an open-top carriage, which looked a bit like the iron-skinned carriages of coal trains in his previous life. Because it was a personalized custom-made product, it was more expensive than ordinary carriages.

Open-top carriages can also be equipped with "armor", but only on three sides, and the resources consumed will not be reduced.

Thus—

His "Stellar" train now had its ninth carriage, an open-top carriage.

Immediately afterwards.

"Huff."

Standing in the train car, Chen Mang let out a long breath before lighting a cigarette and looking up at the starry sky, his expression somewhat dazed. Sure enough, white-grade accessories were more suitable for him.

The basic attribute of the repeating ballista was that it could fire 1 bolt per minute.

Each bolt was about the thickness of a baby's arm and a full fifty centimeters long, made entirely of refined steel, with sharp-edged arrows exuding a bloodthirsty aura.

You could call it an arrow, or you could call it a siege weapon!

After being upgraded to level 10.

It could fire 10 bolts per minute, and the overall image had also undergone a major change, becoming even more breathtaking. The bolts became wider, changing from the original baby's arm thickness to the thickness of an adult's arm, and the length also reached eighty centimeters.

This thing...

If it was really aimed at a human to shoot, the other party shouldn't feel too much pain.

Especially the two super-mode effects brought about by the upgrade.

-

「Repeating Ballista Level 5 Super-Mode Effect」: The repeating ballista can be linked to the 'Train Auxiliary AI'. As long as the enemy is within the search radar range, the Train Auxiliary AI will automatically lock onto the enemy, greatly increasing the hit rate. Requires the green-grade accessory 'Train Auxiliary AI' to be upgraded to max level.

「Repeating Ballista Level 10 Super-Mode Effect」: Resource consumption per bolt is halved.

-

This was the second time he had encountered the exact same super-mode effect. The super-mode effect of the level 5 heavy machine gun was also that it could be linked to the "Train Auxiliary AI" to have an automatic locking effect, which would greatly reduce the manpower consumption in the train.

Otherwise, simply controlling these 8 repeating ballistas would require at least a dozen people.

And it greatly improved the accuracy and his control over the train.

Most importantly—

The "bolts" required for this accessory did not require a corresponding production line. It only needed to consume a certain amount of iron ore when operating the "Repeating Ballista", and the corresponding number of bolts would be automatically generated.

Yes, iron ore.

It didn't need copper ore, it consumed iron ore.

And the price was extremely low.

「Level 1 Bolt」: 1 unit of iron ore to create 1 bolt.

「Level 2 Bolt」: 5 units of iron ore to create 1 bolt.

「Level 3 Bolt」: 10 units of iron ore to create 1 bolt.

Even cheaper with the super-mode effect of halved consumption.

"Not bad."

Chen Mang smiled contentedly and walked out of the train car, standing on the wasteland and looking at the last open-top carriage of the train. The ballistas, slightly higher than the carriage, were quietly resting in the night, patiently waiting for the arrival of war.

For a long time to come.

This would be his most commonly used means of long-range attack.

Indeed.

The rate of fire was a bit slow, ten shots per minute, far less than a heavy machine gun, but the power of a single bolt was higher than a single heavy machine gun bullet, plus it was good and cheap, making it more suitable for him now than a heavy machine gun.

After doing all this.

Chen Mang once again created an open-top carriage, and placed four "40-Tube Cherry Blossom Falling Rocket Launchers" in this open-top carriage.

This was a blue-grade accessory.

One required 1000 units of iron ore, and four required 4000 units of iron ore.

He looked at the resources consumed to upgrade to level 2. Just upgrading to level 2 required 1000 units of iron ore. The rate of fire was quite fast, one volley was 40 rockets, and 40 rockets would be fired in one second.

The latest novels are first published on 69shu.

It also didn't need a corresponding rocket production line, it could directly consume resources.

It was just that the price was much more expensive than heavy machine gun bullets.

「Level 1 Rocket」: 10 units of copper ore to create 1 rocket.

「Level 2 Rocket」: 50 units of copper ore to create 1 rocket.

「Level 3 Rocket」: 100 units of copper ore to create 1 rocket.

A full 10 times more expensive.

If all four "Cherry Blossom Falling Rocket Launchers" were equipped with level 3 rockets and fired a volley together, one volley would require 16000 units of copper ore, enough to deplete a level 1 copper mine.

In such a comparison.

The "Repeating Ballista" was still better.

Five days later.

The sky was slightly bright.

This level 2 iron mine at the bottom of the Doomsday Abyss had been mined almost completely. It would be completely mined in at most a week. And today, the level 1 copper mine had been completely mined.

It was just that a brand new level 2 copper mine had appeared next to it, which Chen Mang had created using the "Level 2 Copper Ore Refresh Coupon".

And in these few days.

No accidents had occurred, everything was going smoothly, and Chen Mang had accumulated enough resources.

He had 80,000 units of iron ore and 6,600 units of copper ore.

As soon as it was dawn, the slaves were already skillfully lining up to receive today's breakfast under the command of Old Zhu and others. Chen Mang was sitting alone in the train car, preparing to spend all the resources he had accumulated in these few days in one go.

In the past, some accessories were only upgraded to level 5 due to insufficient resources.

And he had a bit of obsessive-compulsive disorder. Those level 5 accessories always looked a bit unsightly.

It would look better if they were all upgraded to level 10.

First was the Wind Fire Wheel.

Upgrading from level 5 to level 10 required 35,000 units of iron ore.

"Hmm."

Chen Mang nodded, looked at the resources required for the upgrade in the semi-transparent panel in front of him, and silently chose to give up.

Fuck you!

35,000 units of iron ore was enough to buy his life.

He suddenly found that his obsessive-compulsive disorder seemed to be cured. This level 5 Wind Fire Wheel looked quite pleasing to the eye.
