Klein looked at the system notification and nodded slightly.

It was the same as the information he had received.

There were indeed other places in the catacombs world.

As for the second level's transit station...

Klein looked at the map in his hand.

According to the mark, he wasn't anywhere in the catacombs world, but he was standing alone in a pitch-black area.

This should be where the dungeon of the catacombs world was.

If he wanted to leave this place, he could only break the dungeon and return to the cave!

Furthermore, Klein had his own guesses about the transit station.

It was very likely to be at the Blood Ape and Ghoul.

However, what he didn't know was that he had dealt with them back then. He didn't know if the catacomb would continue to spawn!

If that was the case, it was very likely that the group would be wiped out.

Klein had felt that the Blood Ape and Ghoul were extremely powerful back then.

'Forget it, I'll just ignore them. If they respawn, I can just eliminate another wave. After all, only by surviving can I create value for myself.'

With this thought in mind, Klein no longer paid attention to them.

Then, he looked at another item in his hand, a golden treasure chest.

This was a gift from the system.

[You have passed through the strongest treasure chest on the first level! You have two choices. First, open the treasure chest directly and you will obtain some good items. However, with your current strength, this item might not be useful. Second, you can directly make a wish on the treasure chest. That way, before opening it, if the item you wish on doesn't exceed the authority of the first catacombs level, you will obtain what you want. If it exceeds the authority, the treasure chest will automatically disappear.]

Klein swept through the system's prompt.

He didn't expect the treasure chest to have such an operation!

Then, which one should he choose?

If he chose the first one...

Klein looked at his backpack.

Although he had used up all the wind runes, he didn't lack runes for a short period of time, so this item was useless.

As for the souls, he didn't need to strengthen his equipment for the time being, so it was useless.

As for the rest?

Klein shook his head. He had plenty of resources at the moment.

Most importantly, if he had any needs, he could purchase them in the catacombs world, so there was no need for them.

As for weapons?

Klein didn't need any of them.

Could the catacombs world give him a divine artifact?

Obviously not!

It seemed like he could only choose the second one.

Then what should he choose?

Klein looked at his backpack.

At this moment, there was no trace of the Poison Dragon Ghost Gold. Although there was a high possibility of finding clues to beat the Poison Dragon, there was no way to know the answer to the unknown until the very last moment.

Therefore, he could consider this.

Furthermore, Klein wanted a bottle of Holy Potion.

This potion was simply too useful.

An invincible time frame of 3 seconds.

It was enough to make him immune to a fatal attack.

However, Klein still hadn't made up his mind.

This opportunity was very rare.

Therefore, he had to make good use of it.

Then, he looked at his backpack.

Suddenly, he saw the Endless Sword in his backpack.

Then, with a thought, Klein took out the Endless Sword.

[Weapon: Endless Sword +8 (Damaged)]

[Rank: Intermediate-Grade Legend (Original Low-Grade Divine Artifact)]

[Physical Attack +761]

[Magic Attack +912]

[Casting Speed +50%]

[Attack Speed +20%]

[Enhanced Damage Increase +40%]

[After equipping, five elemental attacks will be increased by 50%, and attack power will be increased by 80%.]

[Remarks: After being damaged, the weapon's combat strength will be reduced by 30%.]

[To complete the final repair, the Cosmos Stone is required.]

Looking at the template given by the system, Klein nodded.

The Endless Sword was very important to Klein.

Especially after he had the Power of the Wind magic skill.

The augmentation of the Endless Sword was even more important.

He couldn't find the Cosmos Stones previously, so he could only give up.

However, now was very likely an opportunity.

Furthermore, compared to the first two items...

The Poison Dragon Ghost Gold wouldn't be able to increase Klein's strength for a short period of time.

On the one hand, there were still quite a few blood and gas ingredients that Klein was unable to purchase in a short period of time.

On the other hand, although the Holy Potion was very good, it was only a way for Klein to save his life.

However, not every time would his luck would be so good that the enemy's final attack could be blocked with the Holy Potion.

What if he encountered an even stronger opponent?

Then, even with the Holy Potion, it was likely that he wouldn't be able to win. At most, the opponent would wait until the potion disappeared before doing anything.

But the Endless Sword was different.

The Endless Sword was very powerful.

Once he recovered his original strength, with Klein's current tier 8 strength...

With the addition of the Endless Sword, he would definitely be able to increase his strength by three or four levels.

Furthermore, the Power of the Wind was also very dependent on the strength of the equipment.

The stronger the equipment, the higher the additional damage it would deal. With the complete restoration of the Endless Sword, it would definitely increase the power of the Power of the Wind by a few levels.

With this in mind, Klein made his decision.

Following that, Klein placed his hand on the golden treasure chest.

As for whether the treasure chest would produce the Cosmos Stone that he wanted...

Klein wasn't worried.

That was because unless the first method was to refresh the artifact, Klein would suffer a loss no matter what.

Instead, he would take a gamble and turn the bicycle into a Harley.

He wouldn't suffer a loss on either side!

With this in mind, Klein thought to himself, 'I need the Cosmos Stone to repair the Endless Sword.'

There was no reaction at first.

Klein repeated it a few more times.

There was still no reaction. Just as Klein thought that he had used the wrong method...

Suddenly, the treasure chest on the ground lit up.

The light was filled with endless heat.

It made Klein unable to resist it and fly away.

As Klein left, the treasure chest slowed down even more.

Not only that, the catacomb seemed to have changed.

It was actually trembling.

It didn't last long before a mysterious force tore open the catacomb and struck the treasure chest.

This force was extremely powerful. The moment it appeared, Klein couldn't help but retreat.

After he was safe, Klein looked over again.

He saw that this mysterious force was an invisible energy, but it was extremely powerful. It was so powerful that Klein felt like he was being destroyed just by looking at it.

"What is this thing?"

"Could it be the sky of this catacomb?"

"Or has god arrived?"

Klein couldn't help but guess.

He thought that his strength was already very strong.

Tier 8!

But when he encountered this energy, Klein instantly felt extremely tiny. Under this energy, Klein felt like he was a small boat in a storm, about to be completely destroyed by the storm.

Of course, this thing came and went quickly.

In an instant, the energy disappeared, and everything returned to calmness!
