After leaving the thirty-third catacomb, Klein, Little Wind, and Little Fox had been walking along a small path in the underground world.

Of course, after half a month of training, even without any hints, Klein could rely on the pangolin's ability to obtain information about the area immediately.

At that moment, Klein ordered the pangolin to go down and dig a tunnel to detect the surrounding information.

After Little Wind obeyed, he instantly dug a hole in the ground and went straight in.

Little Fox didn't sit idle either. She used her sense of smell and hearing to observe her surroundings.

Klein probably felt that there shouldn't be any danger in the vicinity.

After all, he kept looking around without any hints.

Therefore, it was a good choice to have the opportunity for the two of them to engage in actual combat.

Soon, the pangolin returned.

He didn't discover any biological information in the vicinity.

It seemed like the Little Fox's result was that there were no other creatures nearby.

In other words, Klein and company didn't have any possibility of being threatened.

Then, the three of them continued walking forward.

He constantly looked at his surroundings, wanting to see if there were any new hints.

After walking for a while, Klein finally saw a hint.

[Attention, there's a Cerberus ahead. It has a very tenacious vitality. It can be revived no matter how many times it dies. The only way to stop its revival is its tongue. Only by cutting or destroying its tongue can it be prevented from regenerating or reviving.]

It was here...

Klein's heart tightened. According to the description of the hint, Klein knew that the Cerberus was definitely not weak.

The crux of the matter was that the ability to constantly resurrect was too much of a bug.

However, Klein was also very clear in his heart.

If he could defeat the Cerberus, he might receive a rich reward.

Coincidentally, the Cerberus could test the strength of the Little Wind and Little Fox.

Little Wind had also detected dangerous creatures nearby, so he barked at Klein a few times.

Upon hearing this, Little Fox immediately became alert and looked around.

"There's a Cerberus in front of us. It can be resurrected indefinitely. If we want to stop it, we can only do so by destroying its tongue."

Klein's mind spun rapidly.

Soon, he came up with a countermeasure.

Following that, Klein voiced out his thoughts.

He told Little Fox and Little Wind.

At this moment, in a cave not far from Klein and company.

A Cerberus was resting with its eyes closed.

It didn't know how long it had been in the cave.

All three heads had their eyes closed.

Suddenly, one of the heads opened its eyes.

It had the best sense of hearing.

Just now, it heard movement nearby!

Soon, the other two heads woke up too.

The whole three-headed dog stood up and looked in one direction.

The movement was getting bigger and bigger.

In other words, the other party was getting closer and closer to it!

The three-headed dog couldn't help but be ready for battle.

Suddenly, a large part of the ground in one of the directions caved in.

Then, a hole appeared!

The Cerberus instantly jumped up and pounced towards the hole!

Boom!

Immediately, smoke and dust flew!

Countless fragments were sent flying.

However, there was nothing in the hole!

The Cerberus was suddenly shocked.

Then, in another direction.

The ground also suddenly caved in.

The Cerberus suddenly turned around and pounced on another hole.

However, there was still nothing under the hole.

Then, another hole appeared in a different direction.

Then, more and more holes appeared.

However, there was still nothing!

The Cerberus became anxious and let out an angry roar.

At this time, something suddenly drilled out from one of the holes.

The Cerberus didn't see it clearly!

It didn't even make a sound!

The Cerberus's three heads thought that they had seen wrongly.

It was probably because it had pounced back and forth, causing its eyes to blur.

However, in the next second, the Cerberus suddenly felt that its back was slashed by a sharp blade.

A gash instantly appeared on the Cerberus's back.

Fresh blood flowed out!

The Cerberus let out a blood-curdling scream.

"Howl!"

The Cerberus was completely enraged!

The three heads tried their best to find the target of their attack.

The underground cavern instantly became quiet and no shadows appeared.

However, following that, a few more gashes appeared on different parts of the Cerberus.

The Cerberus still couldn't find the other party.

It could only feel the immense pain on its body.

The Cerberus's eyes were bloodshot.

It growled.

It swore it would kill them!

Suddenly, the Cerberus felt something moving beneath it.

Then, before the Cerberus could react...

Its four legs sank into the ground at the same time.

The lower half of the Cerberus's body sank into the ground.

It couldn't move at all.

The Cerberus kept struggling, but it was sinking deeper and deeper.

There was a hint of despair in its eyes.

Who were these guys?!
