Don't look up!

He took out his Firestorm Saber and chopped down the withered tree.

Bam!

Now, he could see the height of the withered tree and the situation at the top.

It was six meters tall, and there was nothing above it. All that was left were withered branches.

[System notification: Wood+10]

Klein put away the wood and continued to search for materials with his head lowered.

Suddenly, a crystal fell from the sky.

It rolled to Klein's feet.

Above?

Klein held it in again.

He silently picked it up.

[System notification: Crystal+1]

He had already seen the silver treasure chest, thirty meters away.

He took a step forward.

Thud!

Another crystal fell in front of him.

"What's going on up there?" Klein couldn't help but mutter.

Old man's reminder: Don't look up!

He possessed his body and picked up another crystal.

Following that, with every step he took, he would drop a crystal.

There were a few times when he almost hit him.

He picked it up along the way.

Klein even guessed that the Observer Eye Devil was up there. Perhaps the crystal was thrown down by the Observer Eye Devil.

As long as he didn't look up, the other party would definitely want to constantly attract his attention, and there would be an endless stream of crystals.

After walking another ten meters, Little Wind couldn't help but want to raise his head. However, he was slapped in the head by Little Fox, and he immediately became obedient!

There were a few times when Klein deliberately raised his head, made a feint, and lowered his head.

With that, the crystals continued to fall.

By the time he reached the silver treasure chest, he had already obtained 32 crystals!

If Klein's guess was correct, there might still be quite a number of crystals on the ceiling of the catacomb.

Unfortunately...

If he didn't have any misgivings, he would definitely have looted everything.

[This is a silver treasure chest. It's harmless.]

Klein squatted down.

He opened the treasure chest.

[System notification: Silver Treasure Chest+1]

[System notification: Wind Rune+2]

[System notification: Water Rune+1]

[System notification: Gold+4]

[System notification: Perfect High School Runic Shower Blueprint+1]

[System reminder: Perfect Runic Hand Shield Blueprint+1]

Klein put away the other items.

He held a blueprint in each hand.

He looked at the details.

[Perfect High School Runic Shower Blueprint: A daily runic device that requires a small amount of water to be used. The device will spray out water vapor and use the least amount of water to clean the sludge on the body.]

[Perfect Runic Hand Shield Blueprint: A combat runic device. Small in size, it can be worn on the wrist. When activated, a wind shield will be produced to counteract a certain degree of attack.]

The two blueprint blueprints had their own uses.

Klein learned them all.

The synthetic materials weren't complicated. The shower needed wind runes, water runes, and fire runes, while the hand shield needed wind runes and earth runes.

Unfortunately, he, who had just been squeezed dry, was unable to meet the requirements of the production!

There were no other resources in the catacomb.

Klein swept the area briefly, took out his shovel, and prepared to find a direction to dig in.

At that moment, a series of shouts came from above.

It sounded like they were coming from afar.

The tone was strange, but it wasn't the common language of the underground world.

"Is it the Observer Eye Devil?"

Klein thought for a moment before saying, "It really has been up there the entire time. If I don't look at it, it probably has no choice but to shout to pique my curiosity."

Klein found it funny.

'No matter what method you use, I won't even look up at you!'

'I can't dig up and behind. There are only four directions left...'

Klein looked through them one by one and chose to continue digging forward.

There was a pretty good crypt creature there.

'I'll choose it for the second living meat field!'

Huff, huff.

The tunnel became deeper and deeper.

"Ah!"

From behind came the ineffectual roar of the Observer Eye Devil.

Klein smiled.

He'd be pissed, too.

Tossing for so long, the fish just don't lift the head to see one eye. How could it not be angry?

..

[Keep digging. It's all hail. There's an Iron Treasure Chest under the ice. There's a Snowdrift Ox in the snow. Don't stay here too long or you'll freeze to death.]

The golden prompt in front of Klein jumped slightly.

The shovel fell.

A black hole that led to the next catacomb appeared.

Klein had already seen the terrain of lava, so it wasn't surprising for the ice and snow environment to appear again.

As for the Snowdrift Ox, he had just checked the illustrated manual.

Danger Factor: 35

It was able to condense an ice armor on its body, but it could be hidden among juniors. For intruders, it was often a charge that would cut the enemy in half!

It made a living by eating snow.

The meat was tender, and due to frequent exercise, its body was much thinner and chewy.

Its weakness was that it was easy to get carried away, so it didn't look at the road when charging.

Any color would provoke it. It would charge forward until the end, knowing that it would stop if it bumped into a hard object.

Its ability was to charge forward at an extremely fast speed. A sturdy armor would often shatter in a single hit, giving it immense strength.

Klein had the air superiority, so he could use the lightning crossbow to subdue this fellow.

He thought for a moment before saying, "Load the arrows with anesthetic first."

In front of the forbidden zone, he changed the crossbow arrows.

From time to time, the incompetence and fury of the Observer Eye Devil could be heard from behind, but it still didn't give up!

"Pitiful worm," Klein muttered. "Be careful when you enter. Let's go."

Klein turned around and instructed the two little things. He took a step forward, and the environment in front of him changed.

The howls of the Observer Eye Devil were isolated behind him, and they could no longer be heard.

"Hiss, it's so cold."

Klein shuddered.

The cold assaulted his face.
