Full health is the kill threshold, no matter if you're a god or a demon!

Liu Nian's ordinary attacks all deal damage of at least 10 billion or 8 million, and his skills deal even more, sometimes billions or tens of billions... So this BOSS's mechanics really do counter him!

But Wu Zhan and his group are different. With a level advantage of over 200 levels, even though they now have skills that boost health, none of them can deal more than 1 million damage to the boss...

So they made it pretty smoothly. This boss's only annoying mechanic is that it has a really bad mechanic.

But it is precisely this mechanism that is so troublesome.

Normally, a level 400 boss should be dealt with by players around level 400!

For players around level 400, dealing over 1 million damage is not even a basic feat.

But once this mechanism is introduced, it will definitely leave them dumbfounded... Everyone is trying their best to increase their damage in various ways, who the hell would learn a skill that reduces their damage!

Helpless, Liu Nian could only deal with the other elite monsters around him.

Fortunately, these monsters didn't have this mechanic, and Liu Nian took them all down with a single punch!

The remaining 59 team members worked together to slowly whittle down the BOSS's health.

This thing also has several disgusting healing and life-stealing skills. It took the team more than an hour to figure out its mechanics, and in the end they managed to grind it down!

As soon as the BOSS was defeated, everyone was surrounded by flashes of white light, instantly leveling up several times!

The equipment that dropped was too high-level to use, so the rest were various materials and gems, which the group collected.

Liu Nian and Kal'tsit went to the throne and looked at the complete metal plate on the wall, which was covered with dense lines and symbols.

"President! It's complete!" Kal'tsit's eyes sparkled as she tiptoed and reached out to touch the engravings on the metal plate, her fingers slowly tracing the lines. "Look here—this is the pipe layout, this is the valve location, this is the access port number. And here, this symbol represents 'shaft,' this represents 'pump station,' and we're currently in the gas room..."

Liu Nian didn't speak, he just stared at the picture.

The overall outline of the image is a bullet-shaped structure—sharp at the front, full in the middle, and narrow at the rear.

Countless pipes extend from the "bullet head" position, spreading across the entire structure like blood vessels, and then converge into several thick main trunks at the "bullet tail" position.

"This shape doesn't look like a city at all," he muttered to himself.

Kal'tsit tilted her head and looked at it for a while: "It doesn't seem like it. Cities are generally structured in regular or irregular geometric shapes, and their internal sewers are usually radial or grid-like. But this..."

Her finger traced an arc on the metal plate: "This looks more like... a cross-section of some kind of vehicle."

Liu Nian's eyes lit up.

Vehicle!

He recalled what he had seen before—pipes, cables, control consoles… and mechanical components whose precision far exceeded that of engineering dwarfs.

Could this be some kind of super-large self-propelled tank?

"Can you read the circuit?" he asked.

Kal'tsit nodded. "Roughly. Piping diagrams are meant to guide people. Look here—" She pointed to the lower center of the metal plate, "This is where we are right now. The bottom layer, near the front. Judging by this scale, this thing is incredibly large! Definitely no smaller than a medium-sized city!"

Her finger moved upwards: "Look at the warhead area, the space is very small. If it were a vehicle, it would be the cockpit or observation compartment."

Then they moved down: "This is the second floor. The space is much larger than the first floor, and the pipes branch here, indicating multiple functional areas. But this is the most worthwhile place to visit—"

Her finger stopped at the lower middle part of the metal plate, where seven or eight thick pipes converged to form a large circular space. The area around the circular space was covered with dense symbols, more so than anywhere else on the map.

"This is the heart of the entire pipeline system," Kal'tsit said. "All the main pipes converge here. The space is enormous! It could very well be some kind of engine or power core!"

Liu Nian stared at the circular space.

His intuition told him that this must be the destination of Lie Lin's journey!

"How do I get there?"

Kal'tsit's fingers moved across the metal plate, tracing a thick pipe line from her current position to the circular space.

"Go through here, then here, into a main passage. And then—" she paused, "there's a marker here. I don't recognize the symbol, but it must be some kind of area. It's on the main passage's main route. Go around here, then along this, this, and this. Finally, go through here and you'll get there!"

Liu Nian glanced at the symbol. It was a gear with vines wrapped around it.

Liu Nian called over a few Demon Bear Clan players and asked them to help dismantle the thing.

Because the object was too large and there was no way to store it in his storage space, Wang Mian simply took out a scroll and made a rubbing of the image.

"Liu Nian! There's a diary here!" Yun Xiangrong's voice came from the pile of spoils.

Liu Nian walked over and took a thick metal book from her hand.

The cover is dark silver with exquisite embossed patterns—it has a distinctly engineering style, and it is clearly not something that could be from cavemen.

There was another line of text on the edge of the cover, but Liu Nian didn't recognize it.

He called Kal'tsit over and asked her to help him identify it.

Kal'tsit glanced at it and said, "This is a dwarf script. The text reads: To those who come after—may the stars guide your path."

Opening the cover, the inner pages are also made entirely of some kind of ultra-thin metal, and they remain intact after who knows how many years.

The characters on it were engraved with a special pen, the strokes are neat and precise, and they have the quality of a meticulous craftsman.

Kal'tsit glanced through it, summarized, and said, "This is a diary left by a gnome adventurer named Morse. It mentions some things he encountered while exploring this place... This Morse said that this is the Omnic ruins he has been searching for, and he said in a very excited tone that their ancestors came from the stars... He seems to have discovered some evidence proving that their Engineering Gnomes are related to the Star Gnomes of the Omnic Wars, and are the degenerated descendants of the Star Gnomes..."

As Kal'tsit flipped through the pages, she recounted, "...The last entry in the diary is that he decided to find a way to restart the engine here and get this place moving...The rest is blank. It was probably lost after that and obtained by the cavemen."

Liu Nian put the diary away. Although it didn't provide any specific or valuable clues, he did learn that engineering dwarfs did exist here, which was still a gain.
