A Level 1 Energy Stone can work continuously for 180 days.

Extremely cost-efficient.

While not very useful elsewhere, it's quite useful here. These robots can significantly shorten his mining time, as "Titanium Crystal Ore" and "Iron Ore" have already been fully mined.

Only "Red Heart Rock Ore," "Copper Ore," and "Wood Field" remain unmined.

The component was immediately crafted.

And consumed.

By upgrading with 4.5 million units of iron ore, it was raised to Level 10, gaining two corresponding Supermodel Effects.

-

"Robot Research and Development Center Level 5 Supermodel Effect": After installing this component, the manufacturing consumption of all robots produced by train components is halved.

"Robot Research and Development Center Level 10 Supermodel Effect": The manufacturing consumption of all robots produced by train components is halved again.

-

Two insane Supermodel Effects.

This means...

The price of a mining robot is only 2,500 units of iron ore.

This price.

Is somewhat akin to clearing out inventory.

"Phew..."

Chen Mang exhaled with some satisfaction; the most important thing is not only the halved manufacturing cost of the mining robots, but the consumption of all robots produced by train components is halved, even including the "Black Hole Armored Robot."

That component itself already has the effect of halving manufacturing consumption.

The two effects stack together.

What can be confirmed is.

In the future, he can definitely deploy an army of robots!

Raising the "Robot Research and Development Center" from Level 10 to Level 20 requires 14.5 million units of iron ore, while currently, the train only has 10.12 million units of iron ore, which is insufficient for further upgrades at the moment.

We'll see about it when there is more iron ore later.

Craft!

In the next moment—

From the Gate of Space in Carriage No. 2 at the "Mecha Research and Development Center," a line of robots, entirely black, filed out one by one through the train doors, staying quietly outside the train without making a sound.

They stood in rows.

Quite quiet.

Extremely orderly.

He used 5 million units of iron ore to craft 2,000 "Mining Robots."

He also consumed 1 million units of iron ore to craft a Level 1 Energy Stone for each robot, ensuring each could work continuously for 180 days.

The scene was quite breathtaking.

...

"Good, good, good!!!"

Chen Mang stood outside the train with a satisfied expression, looking at the 2,000 mining robots in front of him.

When the population reaches a certain size, and this group completely obeys you, even a coward who is usually timid and afraid will feel a rush of heroism inside!

With a glance.

The shock was extremely intense.

Those produced on the assembly line, basically, one can be produced every few seconds, extremely fast.

With 800 people, one can reach the Black Tortoise Gate.

Let alone with 2,000 people.

800 people have a strategy for 800, 2,000 people have a strategy for 2,000.

"They're all industrial trash."

Ai, standing beside, walked up and pointed to one robot at the front, saying, "Train Captain, look, this robot's structure is lacking everything; it doesn't even have the Mechanical Eye, or a signal receiver, which means I can't remotely control these robots in real-time."

"These robots can only complete tasks according to pre-set instructions."

"No transmitter either."

"No AI chip either."

"Forget about armor; they don't even bother using synthetic skin. The frame and wires are all exposed. It looks like one hit could smash them to pieces."

"Indeed, you are right."

Chen Mang nodded with a grin, "But it only costs 2,500 units of iron ore; if it sold for 500,000, I'd definitely call it industrial trash like you say, but it's so cheap that I can't complain."

"Have the instructions been set?"

"Yes, they have."

Ai answered seriously, "After standing here for another five minutes, they will head to the 'Red Heart Rock Ore' nearby for mining work, and after mining the Red Heart Rock Ore, they will mine the other sites. Once all mining sites are completely mined, they will return to the Fixed Star."

"New instructions can only be deployed after these robots return to Carriage No. 2, and no new instructions can be given during mid-operation unless I run over and open their brain-machine interface to manually input new instructions, but that would be a huge undertaking."

"This is truly industrial trash."

"A robot that can't receive command in real-time shouldn't exist in this era; it should be thrown into the shredder of the junkyard."

"Don't say that." Chen Mang said with a cheerful smile, "They're all good babies of the Fixed Star, go study whether there is a way to sell these robots to other trains."

"It requires changing the underlying permissions; the default permission is loyalty to the Fixed Star. I don't have the authority to change the underlying permissions of other robots. This authority requires you, Train Captain, to return to the train control panel and sign an agreement to grant me temporary permissions, then I can see if the underlying permissions of these robots can be changed."

"Alright."

At this moment—

Several residents responsible for daily life usually have come off the train carrying a batch of newly crafted Level 4 pickaxes and placed them on the ground.

Five minutes later.

This batch of mining robots began to move; the leading robot picked up a pickaxe and slowly walked towards the distant Red Heart Rock Ore, step by step, like the steps of a devil.

Stand firm, raise the pickaxe, and start mining.

The entire process was extremely mechanized, with each action so standard that even the height of the raised pickaxe was exactly the same.

As more robots joined, many parts of the distant Red Heart Rock Ore were filled with robots, and the sounds of mining clattered one after another. Although there were only 2,000 of them, because they could work 24 hours a day, they could fully achieve the equivalent productivity of nearly 3,000 residents.
