So at this time, Lilith and the others came by chance.

"You have lost a lot of weight recently! Are you studying magic again?"

Lilith looked at Klein's somewhat thin figure and frowned slightly.

In her impression, it was not the first time Klein lost weight. Every time it was because of studying some new magic, or technology, or in liver synthesis and liver equipment.

That's why she felt that Klein might have made some new breakthroughs.

"This time is not true! This month, I have focused on improving my melee ability. When I go back this time, we will try it."

Klein's smile was very confident, and his strength and physical fitness greatly improved, which allowed him to regain confidence in some aspects.

Looking back on the past, every time a woman says, "If you don't, just take a rest!" is really a very hurtful thing.

Lilith was a little confused. She didn't know what Klein had with this confident expression.

"The ability to fight melee? Are you sure?"

"Of course! You will know my strength now when you go back."

Klein patted Lilith on the shoulder and looked at the other three.

Fortunately, Joe, Betsy, and Eric have all broken through to level 4, which means that the main members of Klein's team have all been level 4.

This is a very strong strength. After asking about the order of promotion for several people, Klein also showed some clear expression.

Qiao was the first to make a breakthrough. Although he was the latest among all, with the super talent of the new human beings and his unremitting efforts, it was only a matter of time before he could break through level 4.

Klein's Joe's evaluation is also the highest among the three. He thinks that at least Joe has the potential to be super-level, and it is only a matter of time before he reaches super-level.

The second breakthrough was Betsy. Although her talent is very good among ordinary people, she should be the worst among Klein and his team.

However, she worked very hard, and after losing half of her body, her brain circuits decreased a lot, and she became more focused on thinking about problems and doing things.

This is why Becky can quickly break through level 4.

As for Eric, he was lazy and oily, and had a lot of peeing on a lazy donkey, if Lilith hadn't stared at him all day, the time he had broken through level 4 would have been delayed by another two years.

"Very good. We have reached level 4. It's not far from the day we go back!"

At this time, Ay was already carrying the unconscious Nokrien over.

After seeing Lilith, Ay took the initiative to say hello.

"hostess."

Lilith likes this title, not to mention that Ai once taught her the three changes in fighting spirit, so he naturally responded with a smile:

"Hello, Ai!"

Although Klein wanted to destroy Norkrien's will at this time, looking at the firelight bursting from the direction of the Warhammer Academy, he knew that the battle between Qianyu and Nesario had begun.

According to the plan, he had to collect evidence in a short time, because even though Qian Yu was very strong, he still had no absolute certainty to defeat Nesario head-on.

Therefore, Klein's time is very tight, and it is probably unrealistic to let him slowly grind Norkrien's will.

"Prepare to search in and put all the useful information and things you feel useful for me! Take action separately."

"yes!"

While several people were preparing to perform the mission, Klein spoke again:

"etc!"

Lilith and the others looked at Klein in confusion. Klein looked at the dark castle in front of him and changed his orders.

"I am in the same group as Lilith, Ay and the other three, and they are divided into two groups of actions."

The few people looked at each other, nodded, and entered the black castle in front of them.

...

Klein and Lilith walked to the left, Eric and the others walked to the right.

Although Braz said that Nesario had only 6 teams under his command and Klein had all been solved, this was Nesario's base camp after all, and there might be some hidden enemies.

Even if there is really no one else, there may be some dangerous traps or mechanisms.

Clay used the worker bee to open the way, and then Little Master was at the front, and he and Lilith walked at the end.

The castle is not big. Not long after, Klein and Lilith came to a laboratory.

There are a large number of blood samples placed here, most of which are of order 4 or above.

On a more conspicuous potion rack, Klein found a blood sample of Nesario himself.

"This guy is obviously a warrior, why did he keep so many blood samples? What exactly is he doing?"

Klein opened the book on the table, which was different from the research data or experimental records that Klein imagined. This is a book about the corrosion of the energy of the void.

"The Hazardousness of Void Energy"

This is a hand-written book, densely filled with notes and some analysis of the energy of the void.

Jieshe also has people who specialize in Void Energy, and they have many experiments and speculations about Void Energy.

The more popular saying is that the energy of void comes from the void and is the natural energy in the universe, but some people in the Jieshe express doubts about this statement.

They believe that void energy is not cosmic energy, but energy converted by some kind of creature after introducing cosmic energy into the body.

Just like a warrior can transform into fighting spirit, a mage can transform into magic power, it is an energy that is actively produced by creatures.

Some researchers at Jieshe believe that void energy is also of this nature.

It is a system different from warriors and mages.

Some powerful professionals will try to introduce void energy into their bodies to strengthen the body and outer skin, which is already a very common phenomenon.

Just like Diluck, he was originally just a relatively strong cold crow. After being baptized by the void energy and strengthened by the synth, he transformed into a top-level 5th-level bird of death.

This is due to the synthesizer, but it is undeniable that the effect of void energy is also obvious.

Klein originally maintained an objective attitude towards both statements until he got the King of Spiral's fingernails in Dillok's lair.

The void energy generated by this fingernail completely corrodes the body of a super-level powerful man, and then gives birth to a small void nest, which is powerful.

In the description of biologist Flando, the King of Spiral should be a super creature of the same level as the Dusk Dragon.

Moreover, the Spiral King was also planned as a monster by Flando, which can explain many problems.

Klein took out the fingernail of the King of Spirals, and the void energy emitted from it suddenly became very intense in the castle.

"What's going on?"

"I guess, who is someone who likes this thing very much? What do you think?"

A voice came from behind Klein, and his pale palm pressed on Klein's shoulder.

Klein shook slightly, and the bone blade in his hand had stabbed backward at the same time.
