I have a Synthesizer

So, Lilith and the others came at just the right time.

"You've lost so much weight recently! Are you researching magic again?"

Lilith frowned slightly, looking at Klein's somewhat gaunt figure.

In her memory, it wasn't the first time Klein had lost weight drastically. Every time, it was because he was researching some new magic, or technology, or grinding synthesis, grinding equipment.

That's why she felt that Klein might have had some new breakthrough.

"This time it's really not! This month, I focused on improving my close combat abilities. When we get back this time, let's spar."

Klein's smile was very confident. The significant increase in strength and constitution had restored his confidence in some areas.

Looking back, it was really a very humiliating thing to be told by a woman, "Take a break if you can't do it!"

Lilith was a little confused. She didn't know what was going on with Klein's confident expression.

"Close combat ability? Are you sure?"

"Of course! You'll know my current strength when you get back."

Klein patted Lilith's shoulder and then looked at the other three.

Fortunately, Qiao, Becky, and Eric had all broken through to Tier 4, which meant that all the main members of Klein's team were now Tier 4.

This was a very strong force. After asking about the order in which they advanced, Klein also revealed a knowing look.

Qiao was the first to break through. Although he started the latest among everyone, with the New Human's super talent and his own unremitting efforts, breaking through to Tier 4 was only a matter of time.

Klein's evaluation of Qiao was also the highest among the three. He felt that Qiao had at least the potential to be Super Tier, and reaching Super Tier was only a matter of time.

The second to break through was Becky. Although her talent was very good among ordinary people, she should be the worst one in Klein's team.

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

This was the reason why Becky was able to quickly break through to Tier 4.

As for Eric, he was lazy and greasy, the kind of lazy donkey that has a lot of shit and piss on the mill. If Lilith hadn't been watching him all day, the time for him to break through to Tier 4 would probably have been delayed for another two years.

"Very good, you have all reached Tier 4. The day we return is not far away!"

At this time, Aiyi walked over carrying the unconscious Nokri En.

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

Although Klein really wanted to torment Nokri En's will at this time, looking at the fire erupting from the direction of the War Hammer Academy, he knew that Qian Yu's battle with Nesserio had already begun.

According to the plan, he had to collect evidence in a short period of time, because even if Qian Yu's strength was very strong, he still didn't have the absolute certainty to defeat Nesserio head-on.

Therefore, Klein's time was very tight. Now it would probably be unrealistic for him to slowly grind Nokri En's will.

"Prepare to go in and search, and pack up all the useful information and anything that feels useful! Split up."

"Yes!"

Just as they were about to carry out the mission, Klein spoke again:

"Wait!"

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

"Lilith and I will be in one group, and Aiyi and the other three will be in one group. Split into two groups to act."

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

......

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

Although Gang Shi said that Nesserio only had a group of six subordinates, and Klein had already solved them all, this was Nesserio's base camp after all, and there might be hidden enemies.

Even if there was really no one, there might be some dangerous traps or mechanisms.

At this time, Klein used the worker bee to open the way, then the Licking Grandpa sensed at the front, and he and Lilith walked at the end.

This castle was not big. Before long, Klein and Lilith came to a laboratory.

There were a large number of blood samples placed here, most of which were above Tier 4.

On a more conspicuous potion shelf, Klein found a blood sample of Nesserio himself.

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

Klein opened the book on the table. Unlike the research data or experimental records that Klein imagined, this was a book about the corrosion of void energy.

"The Dangers of Void Energy"

This was a handwritten book, densely filled with notes and some analyses of void energy.

The Jay Society also has people who specialize in researching void energy, and they also have many experiments and speculations about void energy.

The more popular saying is that void energy is energy from the void, a natural energy in the universe, but some people in the Jay Society doubt this statement.

They believe that void energy is not cosmic energy, but energy transformed after a certain creature introduces cosmic energy into its body.

Just like warriors can transform into Dou Qi, and mages can transform into magic power, it is a kind of energy actively produced by living beings.

Some researchers in the Jay Society believe that void energy also has this kind of nature.

It is a system different from warriors and mages.

Some powerful professionals will try to introduce void energy into their bodies in order to achieve the effect of strengthening the flesh and skin. This is already a very common phenomenon.

Just like Diroke, he was originally just a relatively strong Cold Crow. After being baptized by void energy and strengthened by the synthesizer, he transformed into a Tier 5 top Reaper Bird.

The synthesizer contributed to this, 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 fingernail of the Spiral King in Diroke's lair.

The void energy generated by this fingernail completely corroded the body of a Super Tier powerhouse, and then gave birth to a small void nest, which was undeniably powerful.

In the description of biologist Frando, the Spiral King should belong to the same level of super creature as the Twilight Dragon.

Moreover, the Spiral King was also classified as a magic beast by Frando, which can explain many problems.

Klein took out the fingernail of the Spiral King. The void energy emitted from it was suddenly attracted by something in this castle and became very intense.

"What's going on?"

"I guess, someone really likes this thing, what do you think?"

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

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

"So that's how it is!"
