Now that Abe Ishitaro is missing, Tsunade can only study the brain that is placed in a strange cylinder device first.

First of all, I will observe the removal of the brain, and this Abe Ishitaro's brain removal surgery is very beautiful, and the basic structure of the brain has been preserved intact.

The "people" who worked on this operation had superb surgical skills, and they were even on par with Tsunade at his peak.

Secondly, and it was the one that surprised Tsunade the most.

That is, under Tsunade's chakra perception, the nerves in this brain are still transmitting electrical signals.

This shows that the brain is still alive!

This is a bit beyond Tsunade's understanding.

The former Tsunade can also do it to get the brain out of the human body in such a perfect state, but it is very rare to let a living brain still maintain its activity after leaving the human environment.

Tsunade wasn't sure if he could do it, because removing a living person's brain was a violation of human morality in itself, and Tsunade had never done such an operation.

Moreover, under Tsunade's perception, the function of this brain is not as simple as maintaining normal nutrient intake, and there is also weak neural activity in the conscious area of the brain.

This shows that this brain is not only active, but may even be able to keep thinking!

This made Tsunade more cautious when facing this brain, for fear that if he tilted it slightly, the brain in it would touch the inner wall of the cylinder, causing the brain to die.

If the criterion for judging whether a person is dead is brain death, then in the strict sense of the word, Tsunade's hand is not a brain, but a living human being.

Carefully placing the cylinder on top of the low wooden cabinet, Tsunade carefully studied the curious-style device.

However, in the process of research, Tsunade found himself overly worried.

Although the brain itself is fragile, this cylinder is very protective of the brain.

The green, viscous fluid in the cylinder should be both a culture medium to maintain the brain's nutrient uptake and a protective fluid to protect the brain from external damage, similar to amniotic fluid.

With this fluid, if it is just a normal throw, it will not cause damage to the brain in the cylinder.

In addition to this, the structure of the outside of the cylinder is also peculiar.

Translucent hardened glass in the center, metal borders on either side, and a triangular arrangement of metal slots on the metal frame below.

Each of the three corners of the triangle has a strangely shaped slot, just right to match the other three devices of unknown meaning that Tsunade had dug out of the cabinet earlier.

Tsunade assembled these three peculiar devices and cylinders according to the different shapes of slots and latches.

Something wonderful happened, on that box with two lenses on top, a human face was stereoscopically projected.

That's the face of Ishitaro Abe!

Not only that, but there is also a sound coming from another box with various parts built-in.

"Long time no see, Tsunade."

The words of this greeting barely heard any inflection in tone, and the stereotyped and monotonous metallic voice lacked emotion, but combined with the brain connected to the cylinder, Tsunade had reason to believe that this was what Abe Shitaro was saying.

Or what Ishitaro Abe wanted to say.

Faced with the grotesque and even absurd in front of him, Tsunade has eleven thousand reasons in his heart to deny their existence. These must be the fantasies of some mad scientist or Frankenstein, no less arrogant than Orochimaru's quest for human immortality.

But in the midst of the whirring sound of the three devices connected to the cylinder, Tsunade's brain felt dizzy for some reason.

This chaotic vertigo made Tsunade's vigilance weaker and weaker, and the high alertness in his brain became lower and lower, until the height of the cordon allowed Tsunade himself to converse with the marvelous voice.

"You... Is it Shitaro Abe? Tsunade asked tentatively.

"Of course, Tsunade, my friend, when did you come to my house?"

Such a surprising sentence of reunion between old friends after a long absence, there is no emotion to speak of under the expression of the three devices.

The bland tone and the almost zero change in the mood of Abe Ishitaro's face projected greatly increased the difficulty of Tsunade's understanding of the content of this sentence.

Still, Tsunade tried to keep his sanity and have a normal conversation with the voice coming out of the brain.

"Didn't you write to me to inform me of my coming?"

"Oh, really?" The projected face of Ishitaro Abe finally made a slight puzzled expression, although the next moment it reverted to a stereotypical face.

And Abe Ishitaro's attitude made Tsunade a little suspicious.

If this voice expresses the experiences and thoughts of Ishitaro Abe himself, then the real Ishitaro Abe has never invited himself from beginning to end.

So it's all a trap from start to finish?

Someone pretended to be Abe Ishitaro to write a letter to himself, and in the morning, the impostor also received him.

But this problem goes back to the beginning, how the impostor is impersonating Ishitaro Abe.

And what about the ultimate purpose?

What is the purpose of the impostor pretending to be Ishitaro Abe to invite him?

And Heiji Abe, is he also an impostor?

And the male and female maids of the Abe family, what role do they play in this conspiracy?

In short, there are infinite doubts in Tsunade's heart, and these doubts spin and soar in Tsunade's mind, causing Tsunade to fall into a brain-burning cycle.

However, the sound of the box did not detect Tsunade's doubts, and instead recounted the various curiosities he had captured in his dreams.

"You know what? Tsunade, there is actually a magical creature in this world called Mi Go. ”

"Mi Goe appears to be red crustaceans, but their bodies are closer to fungi. They come from a distant dark country, where they are called 'Yogs', so their race can also be called 'Yogs fungi'. ”

"Mi Goe has powerful wings that allow him to travel great distances to descend into this world, and he can leave this world whenever and wherever he wants."

"What deserves to be praised is Mi Go's insane pursuit of science, their science and technology that are hundreds of years ahead of our world, especially the biotechnology that they are proud of."

"They've found a technique and way to separate the animal's brain from the body, taking the brain out of the body without damaging any of its functions, and then putting it in a special container."

"They can keep their brains for thousands of years with regular replenishment, which is a miraculous technology!"

When this technology was mentioned, the face of the person projected by Ishitaro Abe was unexpectedly excited.

"It's just that Mi Goe has some bad tastes, which is to travel through distant space with the brains of other intelligent beings, in order to show off his skills and ability to fly through distant space to other creatures."

"They also gave a name to this unique sport."

"Interstellar Travel."
