Back when Klein was brandishing his saber, the Rogue Archer must have hidden behind the platinum treasure chest to block the fatal blow.

As for why the platinum treasure chest was able to block Klein's Endless Sword, it must have been because of the catacomb world's system's protection of the treasure chest!

However, even the system didn't know that his action of protecting the treasure chest could actually become a life-saving tool!

Klein raised his eyebrows. This was a good idea. If he were to face a terrifying crisis in the future, perhaps this method could save him!

However, how was he supposed to capture the Rogue Archer now?

Klein frowned.

Klein didn't believe that the Rogue Archer would hide in the row of footprints he left behind when he knew he had been discovered.

But the catacomb was so large. How was he supposed to find it?

Klein looked around.

The catacomb had long been destroyed by Klein's Endless Sword.

There were rocks and broken branches everywhere, as though a doomsday storm had swept past.

It was even more difficult to find the Rogue Archer in such an environment.

Just as Klein was in deep thought, the system's notification appeared.

[Rogue Archer, a born hunter. A tier 6 Rogue Archer has awakened his innate skill, invisibility. In order to hunt it down, wind is very important. You can use large-scale wind magic to stir up the normal airflow in this world. This way, there's a chance for the Rogue Archer to reveal itself.]

Seeing the system's notification, Klein's eyes lit up.

Large-scale wind magic?

Klein looked at his Endless Sword.

With the support of the Endless Sword, the consumption of his large-scale wind spell would be greatly reduced.

However, the problem now was that he didn't have a large-scale wind spell.

The tornado he had used previously wasn't small either. It was about the size of a basketball rack, but it was completely useless compared to the vast space in the catacomb.

Even with the blessing of the Endless Sword, it could only produce a level-10 gale.

It would take at least a few days for a level-10 gale to stir up the entire catacomb.

After all, if a level-10 gale wanted to grow, it would need to be accumulated step by step.

And that was because there were no trees in the underground cave.

If there were trees to defend against it, the level-10 gale would at most blow away half of the trees in the catacomb.

But what Klein lacked the most right now was time.

It was fine if there was anything else, but that mysterious person could attack at any time.

If he couldn't evolve Little Wind and Little Fox as quickly as possible, and if the mysterious person attacked, he would definitely lose a powerful ally. At that time, his chances of winning would be halved.

Furthermore, the last time the mysterious person was injured by the Endless Sword's saber beam, it was due to his carelessness that he didn't choose to dodge. That was how he ended up being tricked by Klein.

This time, when the other party attacked, he would definitely consider the variable of the Endless Sword.

Therefore, he would definitely prepare corresponding means.

If that was the case, Klein's strength would definitely be weakened again.

Therefore, Klein needed to strengthen the two beasts as soon as possible in order to deal with the mysterious person who could arrive at any time.

'Sigh!'

'There are still too few means to deal with the enemy!'

Klein couldn't help but shake his head.

His most powerful weapon right now was undoubtedly the Endless Sword.

However, the Endless Sword had its own problems, such as overconsumption.

With Klein's current magic, he could only cast more than ten saber flashes.

There was no doubt that the saber flashes were very powerful.

Even a mysterious expert who seemed to be at the level of a tier 9 would be severely injured by Klein if he was careless.

However, the saber flashes might be extremely terrifying to small monsters. They would almost instantly kill each other. There was no way for them to escape.

However, to monsters above tier 8, the speed of the saber beam was a huge problem.

Klein still remembered that when he was fighting the mysterious man, the second saber beam had failed to hit the mysterious man.

It had allowed him to successfully open the teleportation portal and escape, and he had handed the third statue he had snatched over to the Giant.

If Klein had a control skill back then and successfully kept the mysterious man, the outcome might have been completely different!

With this in mind, Klein couldn't help but shake his head.

As his strength grew stronger, the monsters he dealt with grew stronger, and the problems he would be exposed to would also increase.

It seemed like he still needed a powerful spell.

With a flick of Klein's palm, a small tornado appeared in his palm.

Wind was a very powerful natural attribute.

There was naturally no need to mention its lethality.

Weren't those famous tornadoes from his previous life destructive?

Once they appeared, they would definitely make everyone extremely wary.

Especially after they matured, there would be massive disasters everywhere they passed.

Therefore, wind was very powerful, and it had unlimited potential for growth.

With a thought, Klein threw the tornado in his hand out.

Instantly, the tornado that was thrown out blew up on the ground, stirring up the dust on the ground.

The tornado was very fast. As time passed, it slowly grew to the size of a telephone pole, and everything around it began to be affected.

But before long, the tornado was stopped by a broken branch.

As the tornado charged past, the size of the branch directly broke through the source of magic within the tornado, causing the tornado to slowly dissipate.

As the tornado slowly dissipated, the dust and short limbs in its body fell out of control and crashed to the ground, stirring up another gust of wind.

Looking at the slowly dissipating tornado, Klein couldn't help but fall into deep thought.

Why were the tornadoes in his previous life able to grow to such an extent that they could destroy the world?

Was it the weather?

Or the environment?

Or was it an opportunity?

Could it be that magic couldn't do it?

Klein couldn't help but frown.

The catacombs world was very isolated. Without the corresponding knowledge, if Klein wanted to obtain powerful skills, he had to start from scratch.

But it wasn't easy.

Magic was mysterious.

It was a spell that was cast by using a special method to mobilize the elements in the world.

Compared to technology that could be traced, magic was even more difficult to understand.

In order to explore the secrets of magic, one had to have sufficient accumulation in order to be able to see a little of it.

This explained why so many mages in the novel world, after becoming the strongest, built their own magic towers.

This was because only when mages had the strength, they would be able to understand magic sufficiently.

Only then could he express his thoughts in words through constant experiments and then carry out experiments one by one.

This was a boring process.

And it was very likely that he could not see the boundary of the process.

But at the same time, once he succeeded, the magic he created would be even more powerful.

Because only the magic he created according to his own needs was the most suitable for him.

Whether in learning, or continue to deepen, it is very important to improve their own magic realm.
