My Doomsday Train.

Chapter 54 Batch Upgrade.

"."

Chen Mang looked at the bread slice that was produced again, took it in his hand and examined it carefully, then put the bread slice into his mouth before looking at the other accessories.

After the "Moldy Bread Production Line" is upgraded to level 10.

Not only has the taste and flavor changed, but there are also two special supermodel effects. Long-term use can ensure that his slaves will basically not get sick, and can also slightly enhance their physical fitness. Although the specific extent of the enhancement is unknown, just looking at the word "slightly", it should not be much higher.

the most important is.

The price has not changed.

It's still 1 unit of iron ore and 10 slices of bread.

Increasing the quantity without increasing the price is great.

He currently has 3927 units of iron ore left, and he wants to upgrade all accessories to level 10, such as the "telescope", as well as the "refrigerator" and "cola production line" that he has not yet built.

The last two accessories are optional accessories for building level 1 trains.

At that time, I didn't have many resources and these accessories were not necessary, so I put them on hold temporarily. Now that I have enough resources, I naturally bought all these accessories.

This is the end.

He made all the parts of the train that could be made.

3829 units of iron ore are not enough to upgrade a white-grade vehicle accessory to level 10. Chen Mang simply stopped today's train construction project and wait until tomorrow to obtain enough iron ore.

The next day, dawn.

As usual, the slaves walked down from the carriage and prepared to line up to receive today's food and water. However, perhaps something unexpected happened today, and unlike usual, the deputy conductor just stood there, with no intention of distributing food.

Just when the slaves were scratching their heads and looking at each other in confusion.

The door of the No. 3 living carriage was suddenly opened, and several baskets were filled with soft bread slices with jam. Chen Mang also walked out at the right time, standing at the door of the train with his cane, looking at the slave in front of him with excitement in his eyes, and the slave behind him who was standing on tiptoe and eager to find out what was going on, he chuckled and raised his hand.

The noise in the scene suddenly became quiet.

"From now on."

"This will be your daily food, delicious bread with jam inside."

"This is my sincerity."

"If you want to always have the best treatment, I hope to see your sincerity and repay me with resources. I will not treat anyone unfairly."

"Now, dinner."

He waved his hand, and Lao Zhu and others came forward to carry the baskets full of bread down and prepare to start distributing them, while he walked to the front of the train alone, considering whether to add another carriage.

There are a lot of things in the train.

It is somewhat inconvenient to always let Lao Zhu and his thugs stay in the same carriage with the bread production line. There is a copper mine here, and he will definitely have to forge enough bullets as a reserve.

Then cargo car No. 2 cannot combine some production lines and mineral resources together.

Give the "pickaxe production line" and other items a separate car, then give bullets and mineral resources a separate car, and give the thugs a separate car. We'll take a look at this in a few days.

Three days passed like this.

During these three nights, Chen Mang would look up at the starry sky as a regular daily activity. The stars that made up the string of words did not change much in either position or arrangement. After nightfall, those stars would always reappear.

In these three days.

He saved up a lot of iron ore, and basically didn't spend a single cent. He saved it all, and together with his original accumulation, he now has a total of 100 million.

"43091 units of iron ore."

It was an astronomical sum. This was the first time he had accumulated such a large amount of iron ore. It was almost enough to buy Ji Chuchu. And he set his sights on——

"Carriage Steel Armor" and "Hot Wheels".

These two green-grade accessories are what he wants to build first. The former determines the defense of the train, and the latter determines the speed of the train.

So far.

The "Star" train, including the locomotive, has a total of five carriages. Each carriage is covered with hard level 1 carriage steel armor. Upgrading a carriage's armor to level 2 requires 5000 units of iron ore.

A total of 25000 units of iron ore were consumed.

All "Carriage Steel Armor" has been upgraded to Level 2 armor.

in the night.

Chen Mang walked off the train, gently stroking the armor outside the train which had become noticeably darker, feeling the strong sense of security it brought him. With this thing, he could basically be completely immune to the damage from level 2 monsters, and ordinary zombie tides could no longer do anything to him.

As for level 3 armor.

Let’s talk about this in a few days. To upgrade the steel armor of a level 2 carriage to level 3, 10000 units of iron ore are needed, which adds up to 5 units of iron ore, which is exactly enough for one Ji Chuchu.

Train defense upgrades are the most expensive.

This is also the most expensive upgrade option among all green-grade accessories.

After upgrading the armor.

He turned his attention to the "Hot Wheels". Upgrading this thing was not cheap. It required 1 units of iron ore to upgrade from level 2 to level 1000.

He consumed 1 units of iron ore and upgraded this accessory to level 5 in one go. He couldn't upgrade it to level 10 because he didn't have enough resources.

There is no special change in the shape of the Hot Wheels body.

Base speed increased.

"Hot Wheels", the advantage of this type of wheel is that it can maintain the fastest speed of the same level in the wilderness, and the basic effect adds a maximum speed of 30km per hour.

Each level increases the upper speed limit by 20 km per hour.

After upgrading to Level 5, the upper speed limit is directly increased by 100km per hour. After upgrading to Level 2, the basic upper speed limit of the train is 130km per hour.

Add the Hot Wheels and take into account its own weight and other factors.

The information given by the "Train Assistance AI" on the control console is that the current upper speed limit of the Star Train is——

254km/hour.

Before the upgrade, it was 156km/h, nearly twice as fast. If he encounters any irresistible crisis this time, he will definitely not be the one running at the end.

In particular, the first super model effect is unlocked when it reaches level 5.
-
"Hot Wheels Level 5 Super Model Effect": It can stimulate the potential state, double the upper limit speed of the train, quickly consume energy stones, and cause certain damage to the Hot Wheels.
-
This supermodel effect can play a great role in saving lives at critical moments.

"."

Chen Mang looked at the train data displayed on the control panel, remained silent, and looked at the "on-board auxiliary AI" accessory. He could actually guess the supermodel effect of some accessories.

For example, the supermodel effect of Hot Wheels is definitely related to speed.

The supermodel effect of the car blade is definitely related to the attack.

But for accessories like "refrigerator" and "car-mounted auxiliary AI", he has no idea what the supermodel effect is, such as refrigerator.
How can this thing have any supermodel effect?

He suddenly wanted to give it a try. After all, upgrading white-grade vehicle accessories consumed much fewer resources than upgrading green-grade ones.
