The Azure Dragon train had just landed on the ground. Upon seeing this light screen, it almost without hesitation, turned around and moved away from this area.

Chen Mang squinted slightly, looking towards the four words "Restricted Area", then left this area as well.

...

On the Shahe Plain.

Chen Mang disembarked from the train, gazing hundreds of meters away at the "Heaven-Reaching Tower", a completely transparent tower filled with countless gears inside, though the gears had stopped turning and had become a restricted area on the Adventure Map.

Restricted Area.

This was the first time he saw these four words.

Staying longer than 10 seconds would invite severe attacks. Who would launch such intense attacks? Perhaps some firepower remnants remain in the Mechanical City, but the Mechanical City has completely collapsed into ruins.

However, he wasn't stubborn enough to want to try and see for himself.

Even though all the gears had stopped moving, from a distance, it still looked grand and awe-inspiring, like humanity's first construction of the Tower of Babel, absurd yet filled with a strong conviction.

The five stages on this Adventure Map, including the S-level difficulty stage, turned out to be much simpler than he imagined.

It didn't feel much like a level...

More like an inheritance.

An inheritance from the Mechanical Civilization.

Especially that Special Tool "Mechanical Heart", Chen Mang looked towards his staff, which now had a ruby the size of a baby's fist embedded at its top, adding a touch of nobility to the staff. That ruby was the Mechanical Heart.

When these two items were put together, they fused automatically.

As if they were originally one.

"Brother!"

At this moment, Er Dan jumped out from the carriage of the nearby Azure Dragon train, taking a deep breath before somewhat regretfully saying, "This Adventure Map can be said to be the simplest one I've ever encountered. I didn't know the content of the last two stages, but from what you said, the first four stages seemed like watching an animation. It shouldn't be difficult."

"Of course, the rewards are a bit pitiful."

"I passed three stages and only got ten thousand units of iron ore and two blueprints, one of which was a white blueprint."

"I bet the reward for your last S-level stage wasn't very high either, right?"

"Hm."

Chen Mang paused for a while, then said softly, "It gave a blue-grade blueprint. Not too bad, at least it wasn't a wasted trip. I still have to thank you for this journey."

"No problem."

Er Dan waved his hand, and a bunch of slaves jumped down from the train carriage, moving cases of beer in front of the Fixed Star train. "I noticed that your people seem to like drinking this beer. I'll give you an extra two thousand cans. I don't have much good stuff here, just this left."

"Actually, the harvest this time wasn't bad, it's just that passing an S-level difficulty only gives a blue-grade accessory blueprint. The last S-level maze I passed, if I could clear it, would have given 30 Murphy Stones. That reward is much richer than a blue-grade accessory blueprint."

"But it's alright."

"I usually like exploring hidden maps. When I encounter a suitable one next time, I'll contact you. Then we can try it together again. If it weren't for you this time, I couldn't even pass the third stage. Thanks a lot."

Chen Mang smiled at the sincere Er Dan in front of him, then motioned to Old Pig beside him, "I hope you weren't laughed at. I don't have anything good here either, just some bread slices. Regular intake can slightly improve physical fitness, better than nothing."

"Store them in the refrigerator, eat them over a year or two, and your physical condition will definitely be better than it is now."

"Alright."

Er Dan didn't refuse, graciously accepting this good intention before walking back to his carriage with a grin, "Alright, until next time, brother."

...

After saying goodbye to Er Dan.

Chen Mang didn't set off immediately, as it was still noon. They only spent about two hours in the Heaven-Reaching Tower Adventure Map.

He didn't have a specific goal for what was next.

Still, he continued to search for mines and continue mining.

But before searching for mines, Chen Mang sat in the train carriage, reflecting on this adventure's gains. The biggest gain was undoubtedly the Special Tool "Mechanical Heart". Although the S-level task was extremely simple, the reward was not weak at all.

-

"Special Tool": Mechanical Heart.

"Special Effect": Creates some basic train accessories, such as chainsaws, lighters, displays, etc. If an accessory requires energy consumption, it can be connected to a generator. Different accessories consume differently.

-

Created accessories cannot be upgraded and are not counted in the total train accessories.

They are considered basic living facilities.

The effect is very useful.

For example, if he found a monitor from before Doomsday in a city ruin, even if he found it, it couldn't be used. Lacking a host is secondary, the main issue is the inability to power it. The "train" generator can only power train accessories after Doomsday; they are not within the same systematic dimension.

But items created with the Mechanical Heart can all connect to the generator.

For those needing independent use, an Energy Stone can be embedded.

Even though it can only create some basic accessories, the ability to freely create through imagination makes this Special Tool inherently strong, worthy of holding up as an S-level difficulty stage reward.

At least, if one placed the Mechanical Heart and 30 Murphy Stones before him, he would certainly choose the former.

Murphy Stones are of no use to him.

They can only be sold or traded with other trains. With Level 0 permission for Unlimited Upgrade, Murphy Stones are not needed at all.
