The craniotomy saw cut into the back of Ivanovic's head as if it were slicing into butter with a red-hot knife, and the sharp blade cut the skull in an instant.

Shen Feng's hand was extremely steady, and the craniotomy saw drew a circle on Ivanovic's skull like a paintbrush, and a round skull the size of a palm had been cut off along with the scalp.

Picking up Ivanovic's scalp and this skull casually, Shen Feng couldn't help but think of the tragic scene of those white Puritans cutting each other's scalps with the Indians when they went to the old North American continent to pioneer.

I wonder if those people are more skilled in their crafts than him?

Place the scalp with the hair and the skull in a tray on the side.

Shen Feng looked into Ivanovic's brain.

A healthy, pink-white brain, soaked in cerebrospinal fluid in the cranial cavity.

Shen Feng carefully observed this brain, wanting to find out what these purifiers were different from normal people in terms of brain structure.

In the end, nothing came of it.

Obviously, these purifiers themselves are just ordinary people, and they do not have organic lesions in the brain like those zombies in the evil spirit virus epidemic.

The impact on them is more purely spiritual.

Jingwei leaned over and asked:

"How? Cerebral angiography? ”

Shen Feng touched his chin and said:

"Direct resonance imaging is fine, inject him with nanomechanical cluster contrast agent."

Jingwei immediately took a syringe, inserted it directly into Ivanovic's neck, injected the contrast agent into it, and finally even the entire syringe drilled into Ivanovic's body through the needle hole.

In less than a minute, Ivanovich's brain had begun to show a silver-gray color, and it was the nanomechanical swarm that had completely penetrated his various capillaries and brain tissue.

Jingwei glanced at Shen Feng again and made a final confirmation:

"This imaging method was invented by ourselves through theoretical derivation, and we have not yet practiced it, so if we don't do it well, it may turn his brain into a pot of porridge."

Shen Feng nodded:

"Let's do it, it's a big deal to die and change someone."

He will not be merciful to these grandsons of the Purification Society.

Jingwei immediately put his hands over the opening of Ivanovich's skull, and let out a buzzing sound.

The nanomechanical clusters scattered in Ivanovic's brain also shook slightly, instantly taking over the internal structure of Ivanovic's brain.

A beam of light shot out of Jingwei's eyes, releasing a hologram of Ivanovic's brain into midair.

Judging from the internal structure, this brain is also relatively healthy and normal, but Shen Feng also found a strange place.

Ivanovic's pineal gland is obviously much larger than normal!

The average human pineal gland is a gray-red oval body 58 mm long and 35 mm wide, weighing 120,200 mg, while Ivanovic's pineal gland has reached nearly two centimeters long and almost one centimeter wide.

Shen Feng couldn't help but raise his eyebrows.

It's so big, is this still called pineal gland, it's just a winter date!

Not only that, but the surface of Ivanovic's pineal gland is not smooth, but wrinkled and numb, and very unrounded.

The role of the pineal gland itself is mainly to secrete melatonin, inhibit the secretion of pituitary follicle-stimulating hormone and luteinizing hormone, and secrete a variety of peptide hormones with strong anti-gonadotropin effects, as well as secrete hypoglycemic factors.

In human history, many mystics have also regarded the pineal gland as the so-called "eye of heaven", believing that if the development of the pineal gland is stimulated or the acquired influence is carried out, the so-called "eye of heaven" can be opened and the future can be understood.

Shen Feng has always scoffed at this statement, after all, this thing itself is actually just a human hormone control valve.

Now it seems that it is difficult for others to say, but the pineal gland may have other meanings for these so-called purifiers.

"Why do these folds of this pineal gland look weird, a bit like human facial features?" Jingwei muttered to himself, while magnifying Ivanovic's pineal glandography and turning it upside down.

Shen Feng couldn't help but narrow his eyes.

The folds on the surface of this pineal gland are a blurred face!

The facial features are vaguely recognizable, and there is also a painful expression, this should be a man's face!

"What the fuck ......" Shen Feng stared at the face, annoyed by this grotesque scene.

Whose face is this?

Could it be the Whisperers?

Does the Whisperer have an exact image of himself?

"Jingwei, search the world immediately to see if there is anyone with this look......" Shen Feng took a deep breath and said slowly.

At this time, he had completely determined that the pineal gland of the purifiers had something to do with the conspiracy behind them.

"We've started searching." Jingwei said, and at the same time handed over a few chips casually, and said:

"Straight into it? Or do you want to do something else? ”

Shen Feng shook his head and said:

"Can't make it too obvious...... Our goal is to temporarily reduce his brain function so that he can be better hypnotized...... I think it's still going to be affected by nanomechanical clusters, trying to put a few microchips in his hippocampus. ”

The hippocampus, also known as the hippocampus, is located between the thalamus and the medial temporal lobe of the brain and is part of the limbic system, which is mainly responsible for functions such as storage, transformation, and orientation of long-term memory.

"I suggest that you also mess with his thalamus, it will be more convenient to hallucinate him or something in the future, and it will be easier to hypnotize." Jingwei said.

The cerebral thalamus is the most important sensory relay station, and the conduction pathways of various senses throughout the body replace neurons in the thalamus and then project to the cerebral cortex.

"That's a good idea, let's do it now." Shen Feng nodded and said.

The two manipulated the nanomechanical swarm, and as they spoke, they began to modify Ivanovic's brain.

Soon, some microchips had been implanted in various parts of Ivanovich's brain by nanomechanical clusters, and his pineal gland was the focus of attention.

However, apart from its strange size and shape, his pineal gland does not seem to be otherwise peculiar.

By the time the brain surgery was done, only a dozen minutes had passed.

After doing all this, Shen Feng took Ivanovic's parietal bone and scalp and put them in their original positions again, and took up a circle of biogum, as if he was just covering a bowl.

Jingwei took a glass jar filled with culture liquid and put it directly on Ivanovich's head, completely soaking his wound in it.

This is the culture medium from the humanoid robot mimicry simulation", which can quickly cultivate biological tissues, and can also kill bacteria and reduce inflammation, which has a miraculous effect on wound recovery.

Except for a little cerebrospinal fluid leakage, Ivanovich did not have much damage from this craniotomy.

"Alright, he'll be almost back in about an hour, and he will be able to wake up then." Jingwei sat on the operating table and said: "If you want me to say, get some biological tissue directly from him, let's go back and plant one ourselves, and then stuff a tactical nuclear bomb in his ass, send it back to the lair of the Purification Society, and just press a button to serve it." ”

Shen Feng rolled his eyes and said:

"And then? Waiting for a new Purification Society to pop up? How could the Whisperer just give up. Besides, the Purification Society is not a fool, can you not see it with a nuclear bomb stuffed in your ass? ”

Jingwei grinned and said:

"Shouldn't your focus be on whether you can fit a nuclear bomb in your ass...... His clothes seemed to be a little strange. ”

Shen Feng nodded:

"Yes, the right side of his chest is more worn than the left, which means that he often raises his right hand to dig things out of the left inner pocket......"

Shen Feng said, reached out and unzipped Ivanovic's jacket, reached into the inner pocket of his chest, and immediately touched a piece of paper.

He took it out casually and found that it was a squarely folded A4 paper, which looked like it was some years old.

Shen Feng unfolded the paper at the moment, glanced at the things on it, and couldn't help frowning:

"These guys seem to have learned to sketch......"
