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

So in the following operation, in addition to clearing out the monsters, Liu Nian also looked around to see if there were any similar metal plates.

He led his team through the shafts and tunnels repeatedly.

Each shaft is basically inhabited by a group of cave dwellers of varying numbers, ranging from dozens to hundreds, with varying levels of rank. Each shaft is led by an elite minor leader—such as bone eaters or skull hunters.

But no matter how many came, they were all taken down by Liu Nian with a single punch.

Later on, Shi Ri and the others were able to help, and the cleanup became even faster.

After passing through five vertical shafts in a row, Kal'tsit, who was already the highest level, has already reached level 183. At this rate, it's not a dream for her to reach level 199 today!

Who would have dared to imagine this before?

After a brief rest, the team selected 59 of the strongest players who had ties with Liu Nian to form the vanguard and advance.

Because the advance detection by the Sun Devourer had already revealed that it was a much larger space than before.

It was no longer a shaft, but some kind of pipe node. When they arrived there, they finally encountered their first boss—a level 400 caveman leader.

It was at least three times the size of an ordinary caveman, with grayish-white skin covered by dark red lines, like blood vessels rising to the surface. Its limbs were extremely thick, and its claws were no longer keratin, but some kind of mineralized substance that gleamed with a metallic sheen in the pale light.

Its head is still flat, but it only has one eye on its head, making it look like a Cyclops.

Behind the "throne" beneath it is a complete wall.

Embedded in the wall was a huge metal plate, at least two people tall and six meters wide. The surface of the metal plate was not rusted, but polished very smooth, and it was covered with dense lines and symbols.

Piping system diagram! Complete!

Liu Nian squinted his eyes.

The caveman chieftain either used that thing as a totem or as some kind of decoration.

In short, this guy is different from other cave dwellers.

Kal'tsit saw it too, and was so excited she almost jumped up: "Guild Master! It's that one!"

The caveman chieftain seemed to sense something. It raised its head, its enormous single eye turning towards Liu Nian, a faint green light flashing for a moment.

Then it stood up.

"roar--!!!"

A deafening roar exploded in the shaft, making the surrounding metal supports hum.

Elite cavemen began to pour out of the surrounding piles of debris, each one over two meters tall, carrying weapons assembled from parts salvaged from mechanical devices.

Shi Ri glanced at it and quickly reported the data.

"Let's go!"

Liu Nian was the first to be hit!

This caveman leader has 249 billion health points, it's worth farming for him!

As for the other grunts, leave them to the rest of the team!

When the BOSS saw Liu Nian charging towards him, he roared and grabbed a piece of metal debris about half the height of a person, then slammed it down on Liu Nian.

Liu Nian smashed the metal debris with a single punch and flashed behind his opponent!

A punch landed!

That punch landed squarely on the opponent's head!

But Liu Nian felt something was wrong; it was as if his punch had hit a hard steel plate!

-0!

The other party turned around and spat out a mouthful of black gas at him without being hurt at all!

The serpent-headed phantom on Liu Nian's body suddenly poked its head out and swallowed the black mist!

-329.87 million!

The Hextech Abilities granted by the Serpent God allowed it to reflect damage!

The BOSS roared again and clasped his hands together towards Liu Nian's head.

"You can also pierce the ears with two peaks?" Liu Nian's figure flashed, and he appeared beside the other party, raising his foot and making the ground rumble!

-0!

"Hmm? It's immune to damage?"

That's impossible! The snake-headed god's spell countered the opponent's attack, and they clearly lost health...

However, Liu Nian did not panic and raised his arm to block the other party's arm that was swinging horizontally.

bang~

The person was knocked backward and sent flying.

It seems this guy's attack has a strong knockback effect!

As Liu Nian was thinking, he saw the other person's arm suddenly stretch out like a white python, grabbing his ankle and pulling him back from the ground!

The arm, as if boneless, grabbed Liu Nian and slammed him to the ground!

Thump~~~~~!

The ground was made of metal, and when Liu Nian was hit like that, his shield dropped by 13 billion!

He instantly activated his Divine Dragon Transformation, forcefully breaking through the opponent's grip, and unleashed a powerful breath!

The hissing sounds continued, but the word "-0-0-0" kept appearing above the other party's head.

This situation doesn't mean the damage is unaffected; rather, the damage has been neutralized or blocked for some reason.

This seems to be different from the invincible mechanism.

Although the cave dweller leader was not injured, he was in great pain from the breath. He roared and summoned a bone shield to block between himself and the breath. Then, both of his arms transformed into long, thin pythons and frantically lashed at Liu Nian's dragon body!

That arm looked soft and boneless, but it hurt Liu Nian terribly when it struck him. Each blow could easily cause more than 5 million damage!

Sometimes Liu Nian's dragon body would coil around the other's body, but when touched, it would feel soft and limp. However, if he used his tail to strike hard, it would feel as hard as steel!

"Non-Newtonian fluid?" Liu Nian thought of something that resembled the other person's situation.

In other words, the leader of this caveman may have a skill similar to his Undying Spirit, which would prevent a certain type of damage from taking effect once it exceeds a certain threshold!

Liu Nian's damage was obviously too high, so none of its attacks could be effective against the opponent!

This is kind of funny...

This is the first time I've encountered a situation where I can't do anything to the opponent because my damage output is too high...

"Damn it!" Liu Nian could only retreat. "Devouring Sun, Martial Warrior, you two take your men and go!"

"What's going on?"

The others were locked in a fierce battle with the elite cavemen when they heard Liu Nian calling out to them.

Is this monster so powerful that even Liu Nian is no match for it?

Then they're even less likely to win!

Upon hearing Liu Nian's guess, the expressions on their faces were quite interesting...

Oh, so it's because we caused too little harm that they let us participate!

This... I really don't know whether to be happy or sad...

"Alright! Let's go!"

The boss fight reverted to the normal group brawl format, and Liu Nian retreated to the side...

There's really no need to use the Heavenly Manifestation Technique in this situation. Who knows what strange monsters we might encounter later? Let Wu Zhan try it out first.

Once Wu Zhan and the others started fighting, the situation became quite normal.

As expected, Liu Nian's guess was correct; it was indeed because his attack power was too high that the opponent was immune to damage.
