Chen Mang said expressionlessly, "28.371 million meters minus 280,000 meters, is that 371,000 meters?"

"That's a humorous joke, Train Captain."

"It's not funny at all."

"Okay, I will continue to learn."

This genius plan just emerged, but it can be abandoned. A Level 100 Drill can only penetrate the ground to a depth of 280,000 meters, and it's unknown how long it would take. The speed continually decreases, and to reach the earth's core, even Level 1000 might not be enough.

That's only considering the drill.

Not considering other factors.

Such as whether the train can withstand such pressure, and the earth's core temperature.

This idea can be basically dismissed.

In that case, we can only wait for this transaction to be completed, then look for a Level 4 Iron Mine, or follow the Train Tunnel to see if there are any opportunities waiting for him in the Mechanical City.

...

"..."

Next to the Constant Star Train, a man with a black dragon tattoo on his arm, in the Steel Dragon Train, was gently stroking his tattoo with a complicated expression, looking towards the distant Constant Star Train.

Speaking deeply after a shallow acquaintance is a taboo.

Master Mang didn't reveal many things to them in detail, and naturally, they wouldn't disclose any family secrets either.

Like his tattoo.

Actually, it wasn't tattooed before Doomsday, but after, belonging to a Special Tool.

It's his secret stash, naturally impossible to tell anyone. He is currently mining a Level 1 Iron Mine, and in fact, he has long completed that S-level Adventure Task, and the rewards have long been obtained. This has been quietly conveyed to Master Mang, and the reason he still buys the mine is purely to support the market.

After all, he saw not many buyers and worried about Master Mang's embarrassment, so he bought one of the mines.

And just now, he saw Master Mang carrying a fluffy toy off the train, placing it aside, then firing a round of machine gun shots, yet the plush doll was unharmed.

No surprise.

It must be another Special Tool.

The Constant Star Train feels like it's hiding many things, much more than he has hidden.

At least...

The white gloves Master Mang was wearing, the cane in his hand, the badge on his chest all seem to be Special Tools, feeling as if he's almost filled with them. How many Adventure Maps has he gone on to get so many things?

Does he not mine typically?

And how did he get the means to create Level 1 Iron Mines? Is it the effect of attachments?

If he can create Level 1 Iron Mines, he should be able to create higher-level ones, right?

His eyes flashed with unusual light; to be honest, if not for reason suppressing him, he really wanted to try suddenly attacking to see if he could take out Master Mang and then naturally claim the Constant Star Train.

But reason told him.

If he attacked, he would most likely be the one who dies.

...

Meanwhile, inside the train compartment, Chen Mang squinted slightly, looking at the message still pinned to the Train Radio.

"Level 10 Mechanical Train, Constant Star": Selling Level 1 Iron Mine extraction rights, complete iron mine, clear property rights, only three mines available, while supplies last, highest bidder wins!

There's actually nothing wrong with this statement!

His business is also fine, but just not many customers.

He thought of two ideas at the time.

The first was to directly sell the Special Tool "Drill's Will," nearly locking in a portion of the customer base. Customers in need would definitely buy, but more customers don't need it.

The second was to directly sell an unknown S-level reward, essentially using the S-level difficulty task as an endorsement to sell expectations, attracting more customers.

However—

Just now, he thought of a third idea.

It came from seeing the upgrade conditions for elevating the train to Level 11, providing him with inspiration.

He remembers one of the conditions for upgrading to a Level 10 train is completing a B-level difficulty task. Any task will do, tasks within Adventure Maps, profession change tasks, etc., but just this condition alone has blocked many people.

After all, B-level difficulty isn't that easy to complete.

A Level 10 train is a watershed, blocking trains with high levels but poor foundations.

His third idea is to create demand!

No one knows if future train upgrades will have a condition requiring completion of an S-level difficulty task?

With the precedent, such a condition isn't impossible later.

And S-level difficulty tasks, whether on Adventure Maps or profession change tasks, are extremely difficult to complete, few can achieve it.

But here—

Only 1.5 million units of iron ore are needed to complete an S-level difficulty task, to prepare for future guarantees so you won't be blocked later, and can receive an S-level Adventure Task reward.

Isn't this tempting enough?

He immediately republished the advertisement.

The effect was immediate.

Almost within minutes, four or five Train Captains said they were on their way to the coordinates, only... still did not reach the explosive scenario he imagined.

"..."

Chen Mang frowned slightly, isn't it cost-effective?

1.5 million units of iron ore, buying an unknown S-level Adventure Task, and a future guarantee, isn't it worth it? If it were him, he would definitely buy!

Minutes later.

He silently lit a cigarette, understanding the demand exists, but...there's no market.

The "Adventure Task" is a publicly available Adventure Task; each train can only take it once, and many trains have already taken on this task long ago, even if they want to buy, they don't qualify to buy.
