Beneath a vast plain in the Land of Rain, there is a huge underground cavern that doesn't look like it could be created by humans.

It's like a miracle left by a god on earth.

There, a major experiment was being carried out to determine the fate of the world in the future.

In the middle of a huge underground cavern, there are connected laboratories.

At this moment, in the cave, a tall figure had a smile on the corner of his mouth, and his deep eyes looked at the laboratory in front of him, and he was slowly walking towards it.

When this figure walked into it, the personnel who were conducting research inside were stunned, and couldn't help but say respectfully.

"Aizen-sama!"

"Blue... It's Lord Aizen who is here... Look!"

At this time, the research institute was no longer the only one in charge of research.

Kazumi, who had previously worked as a basic researcher, was still one of the heads of the entire underground research institute at this time, and co-led the project with Orochimaru to support the entire "Great Void Era".

Naturally, as an unimaginably huge experiment, the number of researchers needed is definitely at the plural level.

Among them, Kinnara was in charge of intervening, and some of them were recruited from various countries, and some were kidnapped.

In this way, gradually, the entire underground research institute has dozens of experienced research experts!

And all this happened quietly and secretly, and no one was aware of it.

As the leader of the Rain Country, Kinnara has been hiding the strength of the Rain Ninja Village for all these years, but secretly, it is a state of symbiosis with the Void Night Palace.

The underground research institute of the Void Night Palace has cultivated batches of elite ninjas for the Rain Ninja Village.

Until recently, after the return of Aizen, the experimental plan on the void was officially launched, and the suitable teenagers and girls were selected from the rain ninja village for training.

In a way, this policy is somewhat similar to the blood mist policy of the Mist Ninja Village back then.

It's just that, compared to the nearly 90% elimination rate of the blood mist policy, the virtual experiments completed and carried out by the children are much larger in the end.

Even the worst DX-G1 reagent is currently used, and the survival rate is 80%.

It's just that for the Void Night Palace, all that is needed is a talented elite boy.

Some of the unqualified were sent back to the Rain Ninja Village, but even so, their future was limitless.

And the excellent qualified ones have become the reserve personnel of the Void Night Palace, as a reserve force, stationed in the Void Night Palace, and received training from all people.

At this moment, when Aizen enters the laboratory.

All the researchers couldn't help but put down what they were doing and stood in a row, surrounding Aizen, looking at him with reverence in their eyes.

For this group of people who have devoted their entire lives to research, the reverence in their hearts is beyond words to witness the initiators of the "Great Void Era" that can change the world.

They will never forget the shock and disbelief in their hearts when they first heard the research order issued by Kazumi.

Until this time, the research of the void has progressed to the current unbelievable stage, and all this is like a dream for this group of researchers.

Who would have thought that he would suddenly become one of the people who changed the rules of the world?

It is precisely in this way that the reverence in their hearts for indigo dyeing is the depth from which they cannot extricate themselves.

Seeing everyone's reverent eyes, Lan Zhan still maintained a calm smile on his face, and his deep eyes glanced at them, and his voice was very gentle.

"I heard that you discovered the cause of the mutation of the virtual body?"

Hearing his words, the researchers looked at each other, and then looked at an old man inside.

I saw an old man with gray hair, reading glasses, and a wrinkled face standing up tremblingly, and said very respectfully and hoarsely in front of Aizen.

"It was the old man who was lucky enough to notice it, and when he experimented, he finally discovered the mystery. ”

Hearing his words, Aizen glanced at him with an approving gaze and said softly.

"It's really remarkable, I thought that Orochimaru or Kazumi, the two people in charge of the first contact with this experiment, would be able to find out the reason. ”

"I didn't expect that in the end, it was you who made the result, and I am very happy about it. ”

"I want to know your name. ”

Hearing Aizen's words, it was obvious that he was very useful to the old man, and the wrinkles on his face were all folded with a smile, and he hurriedly said hoarsely and respectfully.

"I'm really ashamed, the old and decrepit heavy wood temple Wu, it's really a fluke to be able to share some confusion for Lord Aizen. ”

In this regard, Lan Zhan's deep eyes narrowed slightly, looked at the old man in front of him, and said softly.

"You don't have to be so modest, you were able to study the reason before Orochimaru and Kazumi, and naturally you have already proven your strength. ”

"And for the Void Night Palace, what is needed is precisely a talent like you. ”

"I'm looking forward to it..... Your performance in my next experimental plan. ”

Originally, when he heard Aizen's words, the old man was just very pleased, but he was a little afraid to respond.

However, when he heard Aizen's last words, he suddenly stood on the field and was completely stunned.

Not only him, but the rest of the researchers around him also widened their eyes, looking at the old man who was originally among them, Shigeki Terago, in disbelief!

Temple... The seniors of the temple were valued by the indigo-sama!!

At this time, the old man Chongmu Siwu instantly lost his previous promises, as if he had been beaten with chicken blood, and in an instant, the whole person's old appearance seemed to have become much younger!

"Old .. Old decay must be.. I will definitely live up to the expectations of Lord Aizen!"

I saw that his eyes widened, straightened his originally slightly curved waist, and showed a look of being in good shape and a hundred times more energetic, looking at Lan Zhan and shouting excitedly.

Seeing his appearance, the corners of Aizen's mouth hooked and he laughed softly.

"I'm relieved to see your state, so now, take me to see the results of your research. ”

Hearing his words, Shigeki Tera hurriedly arrived in front of Aizen with his hands and feet like a young man, and personally led Aizen forward, and the two slowly entered the internal laboratory.

After the two left, the rest of the researchers still had disbelief on their faces.

It wasn't until half an hour later that someone muttered.

"Just... It's been valued by Lord Aizen..."

Someone on the side sighed.

"Indeed, I'm afraid that the predecessors of Siwu will not be the same as in the past..."

"To be able to take the lead in participating in the experiment of the indigo dye master who proposed the 'Great Void Era', no matter how you think about it, it makes people feel envious!"

Hearing this, someone else couldn't help but glance at him and muttered.

"What's more... I'm more curious about the fact that the 'Great Void Era' has been able to change the world. ”

"So.... What kind of great results will the next experiment create.....

Hearing his words, everyone fell silent.

For this group of researchers, strength is nothing they are looking for.

Only what they do will have an impact is what they are after.

There is no doubt that they are willing to stay here!

Because.... Here they have changed the world ....
