Klein retreated as his mind spun rapidly.

There had always been a question.

If the two of them dug from both sides of the wall at the same time, would they meet halfway?

Klein had also thought of another scenario.

It was possible that the black membrane didn't mean that they had dug through. It was just a teleportation portal.

Or perhaps, both sides had entered the black membrane at the same time and couldn't touch it at all.

Klein wanted to go. He was unwilling to leave by digging another catacomb.

He coveted the silver treasure chest!

At the same time, he thought of making a trip to the abandoned Earth Dragon nest.

'Why don't I take a risk and give it a try?'

Klein thought about it and felt that this method wasn't reliable.

The main reason was that he hadn't tested it.

Lure the Sand Troll away? Or try to fight the Sand Troll?

Klein took out the runic crossbow and calculated the chips in his hands.

First, he had an anesthetic, a runic crossbow, and the ability to fly.

Second, he still had the Skeleton Potion that he hadn't produced, and he still had a pet that he hadn't released.

If he produced the egg, he could add another helper.

Perhaps it would be a particularly awesome pet?

Klein didn't hesitate any longer.

He immediately sliced open his finger and dripped his blood onto the runic egg.

Just like the day Little Fox was born.

The silver-white patterns on the eggshell emitted light.

The runic egg shook violently.

Klein placed the runic egg on the ground and simultaneously paid attention to the catacomb where the Sand Troll was located, indicating that there hadn't been any changes.

More than ten seconds later.

The eggshell shattered into pieces.

Under the silver light, the outline of the new pet gradually took shape.

"Pangolin?"

Klein was taken aback

The little thing looked a little like a pangolin, but it was more gas-filled and mechanical.

Its outer layer looked like it was covered in a hard mechanical armor, with sharp edges and corners.

"Yay, yay, yay!"

The little thing's crawling speed wasn't slow at all. In a flash, it came to Klein's feet and circled around him.

Klein opened the pet interface.

He looked at the details of his new pet.

[Tornado Pangolin]

[Name: Unnamed]

[Status: Healthy]

[Ability: Assault Hammer, Terrain Modification]

He looked at the details of his ability.

[Assault Hammer: Instantly increases its speed and uses its hard head to hit the enemy. Lasts for 1 second. Cooldown time: 5 minutes.]

[Terrain Modification: Changes the existing terrain. It can be used to create traps or buildings.]

..

Two abilities. One was offensive, and the other was related to the terrain.

Klein flipped through the Crypt Biology Guide again.

[Tornado Pangolin: It has a hard outer shell. As long as it curls up into a ball, it will be invulnerable. The claws of most crypt creatures are unable to harm it. When it charges, the rocks will shatter. Living in the soil all year round, it can easily excavate and change the terrain.]

This fellow's weakness was that he was overly curious.

The risk factor wasn't high, less than thirty.

However, compared to Little Fox, the Tornado Pangolin was more useful.

If he set a trap in advance, and the Sand Trolls returned...

Klein already had a good idea.

He thought for a moment before saying, "I'll give you a name too. From now on, you'll be called Little Wind."

'I'll still extract a word from the original name.'

Lazy naming method!

"Yay, yay, yay!"

The Tornado Pangolin bounced on the ground, his pair of eyes turning into a crescent moon. He seemed to enjoy it very much.

Little Fox sized up the Tornado Pangolin. She raised her chin proudly with a hint of disdain.

"Fill the soil back first."

Klein filled up the tunnel he had just dug with sand.

Then, he took the two pets and flew to a protruding rock that was more than ten meters high.

He set up a fire.

He opened the production list.

[Excellent Skeleton Potion: Poison Spotted Grass 12/3, White Bone Flower 10/2, Bloodstained Grass 9/2, Water 7800m/100m, Fire Source]

He took out a stone bowl and chose to make four portions.

[System notification: Poison Spotted Grass-12, White Bone Flower-18, Bloodstained Grass-18, Water-400ml]

[System notification: Skeleton Potion successfully produced.]

A sticky potion appeared in the bowl.

Klein forged a few more sets of crossbow bolts.

He smeared all of them with poison.

Then, he took out an anesthetic and smeared it all over.

After doing all of this, he brought Little Wind back to the surface.

The reason why he had gone up to the surface to produce it was mainly because he was afraid that the Sand Troll would return during this period of time. It was just to be on the safe side.

Klein looked at the notification in the catacomb ahead again.

[There's a Silver Treasure Chest in the catacomb ahead. There's a Sand Troll patrolling its territory. If you try your best, you might be able to defeat it after paying a certain price.]

The notification changed!

It meant that there was a chance to defeat it with the addition of a pet, as well as the preparation of poison arrows and tranquilizer arrows.

Klein thought for a moment and said, "This is the probability of victory for entering the catacomb ahead. If I set up a trap here and wait for it... The success rate will definitely be higher.

"As long as I can hit more than a dozen arrows, I don't believe that the Sand Troll can withstand a large dose of poison and tranquilizers!"

Klein turned around and gave Little Wind an order.

He requested that the large piece of sand in front of him be transformed into a soft, quicksand terrain.

Little Wind did as he was told.

He drilled into the ground, and in less than three minutes, he drilled out of the soil again.

[This piece of sand has a loose structure and belongs to the quicksand terrain. Be careful of sinking into it.]

After Klein observed it, a notification appeared.

Everything was ready except for the east wind!

If the Sand Troll didn't turn back, all the work would have been in vain, but Klein could go straight to the next catacomb.
