The strange rat-headed monster roared and stomped its bent legs against the ground.

A violent shockwave surged, tearing apart the partially devoured human corpses around them, splattering blood and flesh everywhere.

The rat-headed monster vanished from its spot and charged toward Lu Ning, who was at the front, at an extremely fast speed.

Just as Nan Yu was about to attack, Lu Ning raised his right leg, and white light flashed on his leg.

Boom!!

His foot struck the rat-headed monster directly in the chest, and the violent force poured into the monster's body, tearing its chest apart.

His body flew backward like a cannonball, crashing heavily into the metal pipe.

The metal pipe twisted and caved in under the force, and the rat-headed monster's body became deeply embedded in it.

This kick instantly killed the rat-headed monster.

Li Fu and the others, who had been tense and ready to fight back, froze in place when they saw this scene.

Lu Ning's mental fluctuations were only at the fifth level, yet he was able to kill a sixth-level rat-headed monster with a single blow.

Their exaggerated destructive power was almost incomprehensible to them.

"So strong..." A team leader's lips twitched slightly as he whispered.

The other team members looked at Lu Ning with immense awe.

Nan Yu and the other members of the investigation team already had some understanding of Lu Ning's strength, so they weren't too surprised.

Looking at the corpse of the rat-headed monster, Nan Yu said, "This monster seems to have the power of flesh and blood, which may come from the Crimson Cult."

Lu Ning nodded slightly, about to speak, when he saw the flesh and blood around the rat-headed monster writhing and beginning to merge again.

The area in his chest that had been torn open healed at an extremely fast speed, and the dim white mist inside his body thickened again.

"He's not dead yet." Lu Ning was a little surprised.

With such injuries, a person with normal disease would not survive.

Lu Ning thought of the monster in the underground flesh and blood corridor.

His recovery ability is also quite good.

Nan Yu frowned slightly and said, "Such a recovery ability must come from the power of flesh and blood."

Lu Ning did not answer; he took out the Crimson Sword.

As the Crimson Sword appeared, mental pollution spread, causing the expressions of the surrounding action team members to change, with the weaker members retreating one after another.

Lu Ning arrived in front of the rat-headed monster.

The rat-headed monster had regained consciousness, and its ferocious claws reached out to grab Lu Ning.

However, several flashes of sword light streaked through the air, and the claws were instantly severed.

Lu Ning remained expressionless as he plunged his sword into the rat-headed monster's body.

Immediately, the Crimson Sword trembled slightly and began to absorb the flesh and blood of the rat-headed monster.

The rat-headed monster seemed to sense the abnormality as well. A mad glint flashed in its ferocious eyes as it twisted its body, trying to get rid of the crimson sword.

Perhaps because it lacked awareness of pain and reason, the rat-headed monster moved with extreme force, unaware that it was being torn apart by the edge of the crimson sword.

However, Lu Ning stomped heavily on the rat-headed monster's body, suppressing its movements, and the rat-headed monster was unable to escape the crimson sword.

Perhaps sensing its impending doom, the rat-headed monster's flesh writhed, seemingly undergoing a deeper mutation.

However, the Crimson Sword had already absorbed a large amount of flesh and blood, making the rat-headed monster's mutation extremely slow.

After a few breaths, a human face twisted out of his neck.

The face was devoid of skin, making it impossible to discern any features, but his eyes held despair as he pleaded with Lu Ning, "No... please spare me!"

Lu Ning remained expressionless and did not even answer.

In just a moment, the rat-headed monster's corpse was completely absorbed, and the red light around the Crimson Sword gradually dissipated.

Lu Ning glanced at the Crimson Sword; the white mist within its body was growing increasingly dense, seemingly brewing a powerful force.

Lu Ning sheathed the Crimson Sword and returned to the main force.

However, he noticed that Li Fu and the others had all silently taken a few steps back.

Lu Ning looked at them with some confusion: "What's wrong?"

Li Fu was the first to come to his senses. He chuckled dryly and said, "It's nothing. I just didn't expect Commander Lu to possess such a terrifying soul weapon."

Lu Ning nodded slightly: "This is what I earned through my previous efforts."

Karen asked incredulously, "This soul weapon should be close to a high-risk soul weapon, right? How much merit do you need to exchange for this kind of soul weapon?"

Nan Yu, who was standing to the side, laughed and said, "Haha, you probably don't know Lu Ning yet. He has already thwarted a cult's conspiracy."

Li Fu and the others were taken aback, and their eyes showed more respect for Lu Ning.

"I never expected Commander Lu to have made such a great contribution!"

Lu Ning shook his head: "Let's go."

He walked in front again, heading towards a corridor pipe.

This time, he has seen the way.

Although the concentration of white fog in the area where the rat-headed monster was located was not low, there was an even denser white fog around it.

Nan Yu and the others didn't ask any questions and followed directly.

After this incident, Li Fu and the others quietly followed, gaining a new understanding of Lu Ning's strength.

They walked along the pipe for another hour or so, during which time Lu Ning and the others encountered several more mutated monsters similar to the rat-headed monsters they had encountered before.

They are all formed from flesh and blood, but their strength varies. The powerful ones have reached the sixth rank, while the weak ones are at the fourth rank.

These mutated monsters eventually became nourishment for the Crimson Sword.

Lu Ning discovered that the Crimson Sword was particularly interested in the flesh and blood of these mutated monsters.

Considering the side effects of the Crimson Sword, Lu Ning guessed that the Crimson Sword might be related to the Crimson Cult.
