Sheldon looked at Klein and spoke seriously.

Behind him was an extremely large and ferocious-looking beast.

"Is this your crypt creature?" Klein stared at Sheldon.

"Yes, as you can see, this is a crypt creature that obeys me. It's a gigantic wolf-shaped beast. I named it Silver Wolf," Sheldon said.

"You're Klein, right? You're a famous person in our catacombs world. I never expected to meet you here," Sheldon said with some amusement.

Just now, his Silver Wolf had sensed the presence of a living person nearby through its keen sense of smell.

So he came over to take a look. However, he never expected to meet Klein.

Furthermore, there were two crypt creatures beside him.

"Heh heh, as expected of Klein. You managed to subdue two crypt creatures so quickly," Sheldon praised.

Sheldon smiled and said, "I spent a lot of effort to obtain this Silver Wolf. For that, I even paid a painful price and lost three fingers."

Sheldon looked at his broken right hand and looked at Klein.

"However, I didn't expect you to be able to obtain these two crypt creatures unscathed."

Little Fox and Little Wind looked tiny in Sheldon's eyes, and they didn't seem like they had any combat strength.

But for Sheldon to be able to survive for so long and even subdue a crypt creature, his accumulated personal experience wouldn't make him underestimate his enemy.

Underestimating your enemy was a taboo for a fighter!

In the days since he came to the catacombs world, Sheldon had deeply understood this principle.

He would never forget this lesson from the bloody experience.

One had to go all out when dealing with any enemy.

"Yours isn't bad either. With such a large body, it's even bigger than two of mine combined," Klein said with a smile.

After he said that, the two sides were in a stalemate for a few seconds.

No one made a move.

There was a slight silence in the air.

However, the pets of both sides were still in combat mode as they glared at each other.

"Do you want to team up with me, Klein?"

Sheldon finally spoke.

He needed a partner.

To be honest, with his own strength, it wasn't difficult for him to survive.

However, just surviving wasn't Sheldon's goal. His goal was to find a way to leave this world.

Therefore, it was far from enough to rely on him alone.

He needed a partner.

As for the others, to be honest, Sheldon didn't think much of them.

If they were too weak, they would be holding him back.

And right now, Klein was undoubtedly a very good candidate.

His strength was definitely the best in the entire catacombs.

As his teammate, he was undoubtedly the most suitable.

"No, I refuse," Klein said with a cold gaze.

He didn't need any time to think.

"So decisive?"

Sheldon didn't seem surprised, but his tone turned colder.

"Are you sure?"

"Of course."

Sheldon narrowed his eyes and stared at Klein for a while.

In the end, he could only smile faintly.

Sheldon smiled and said, "If it were anyone else, I would definitely choose to silence them and take away all of their belongings. But if the opponent is you, I wouldn't be so foolish as to do so."

If Sheldon had previously thought that Klein was just a very strong survivor with strong survivability, he wouldn't have been so foolish.

But after a few minutes of contact, Klein's calm reaction made him admire Klein a little.

Furthermore, he had two crypt creatures with unknown strength by his side.

If they were to really fight, Sheldon really didn't have the confidence to win.

After all, with his personality, if he couldn't guarantee a 100% success rate...

He would never do it.

"You're smart, otherwise you'd be dead," Klein said coldly.

Sheldon has seen a lot of cruelty in this catacombs world.

But he was stunned by Klein's words for a few seconds.

Then he recovered quickly, turned, and left.

Before he left, Sheldon said to Klein, "We'll meet again in the future. Although your strength is undoubtedly at the top in all aspects, you won't be able to go far by yourself."

With that said, Sheldon and his Silver Wolf disappeared in front of Klein.

Klein naturally didn't care about Sheldon's words.

As long as he could see the hint, he would definitely be able to persist to the end by himself.

Furthermore, he wasn't alone at the moment. Instead, he had two living beings accompanying him to survive in this cruel underground world.

After resting in the catacomb for a while, Klein decided to set off again.

As he walked, he checked if there were any new hints nearby.

Soon, a new hint appeared in front of Klein.

[There are some extremely disgusting strange insects in front of you. These strange insects are far more disgusting than a Sand Troll. Please be careful and don't lose your life.]
