“The sleep states of animals in nature can be divided into REM and NREM, as well as Bsws (bi-hemispheric slow-wave sleep) and Usws (uni-hemispheric slow-wave sleep).

Humans belong to bi-hemispheric slow-wave sleep, characterized by complete immersion, with both the left and right brains in a state of sleep.

Uni-hemispheric slow-wave sleep, on the other hand, is characterized by allowing only one side of the brain to enter sleep, while the other side remains awake,”

Li Ang said slowly, “The most obvious examples are whales, dolphins, pigeons, and mallard ducks.

Sperm whales sleep 8-10 times a day, only about 10 minutes each time, and remain upright and suspended in the sea during sleep.

Dolphins and mallard ducks, during Usws, keep one eye open to observe the outside world, maintaining normal activities and guarding against external predators in a semi-sleeping state.”

*Pa-thunk.*

In his coma, Ma Bangde suddenly raised an arm and then slammed it down heavily.

Immediately afterward, his whole body began to twitch slowly, looking like he was being electrocuted.

Chai Chai exclaimed, “Holy crap, is he dead?!”

“No. With me here, how could he possibly die?”

Li Ang calmly said, “The human brain is like an extremely precise and complex machine, but at the same time, it has a certain ability to repair itself.

In some cases, it can self-regulate, change the partition structure, and assign the functions controlled by certain damaged areas to other undamaged areas.

This talent, known as neuroplasticity, can be utilized by the biological mother lode's modification ability.

With a little guidance, the brain can complete the missing parts by itself and improve itself.”

“Sounds unreliable!”

Miss Chai subconsciously retorted, “Isn’t that like handing a scalpel to the patient and letting them use their instincts to perform surgery on themselves?”

“Slightly different.”

Li Ang spread his hands casually. “The biological mother lode is an extremely powerful and strange prop.

When no one is in control, it will automatically transform any organism it comes into contact with, causing it to undergo substantial mutations—mutations that are largely benign, reliable, and in line with the laws of evolution.

Most of the mutants in that deformed world were able to move freely without collapsing and disintegrating on their own due to genetic mutations. This is almost a miracle in biology.

And when someone is in control, the biological mother lode is also exerting its optimization instinct all the time.

As soon as Ma Bangde's brain comes into contact with its power, it will evolve according to the laws of evolution in the dark.

So this operation is actually dominated by my medical plan, and the biological mother lode and Ma Bangde's brain cooperate to achieve my requirements as much as possible.”

Li Ang paused, his eyes blooming with a light of seeking knowledge, “It’s rare to have a patient who brings himself to the door. With this experience, maybe I can evolve low-level but durable brain structures for all the worms and soldier bees in the future.

In this way, there is no need to use divine power for remote real-time control.

The range of action and battery life of biological weapons can also be greatly enhanced.

But we must pay attention to adding backdoors,

Otherwise, if the biological weapons get out of control, it will not be easy to deal with...”

While Li Ang muttered to himself, he did not forget to continue the operation on Ma Bangde.

Fortunately, Magistrate Ma has always regarded strange dreams as the biggest secret in his life, and he has not even told his wife and children.

When he invited Li Ang just now, he specifically ordered his subordinates to wait outside the mansion, and no one was allowed to enter.

Therefore, the operation can proceed undisturbed.

“Although the level of science in the real world is not yet sufficient to accurately explain the mechanism of uni-hemispheric slow-wave sleep,

However, relying on the biological mother lode’s subjective initiative to transform, and the neuroplasticity of the human brain,

I can still achieve my transformation requirements.

Now, all that is needed is to expand the joint fibers connecting the left and right cerebral cortices of the patient, increase the volume of the corpus callosum, anterior commissure, fornix, and fornix commissure,

Adjust the ventrolateral preoptic nucleus of the vLpo hypothalamus, including the orexin neurons in the LhA brain region and the hypothalamic lateral posterior neurons including the histaminergic neurons in the tmn brain region.

It can make his vLpo structure manage the neural inhibition signals of the left and right brains, shoulder the information interaction and physiological regulation of the left and right brains during uni-hemispheric sleep,

Then it will affect his sleep and wakefulness physiological cycle.

In short, it is to transform his brain into a structure similar to that of a dolphin...”

*Pa-thunk, pa-thunk.*

Ma Bangde twitched more violently, sticking out his waist like a live fish and jumping back and forth on the ground.

“That...”

Miss Chai couldn’t help but ask, “Is he okay?”

“Should be fine.”

Li Ang looked at Ma Bangde, who was jumping back and forth, and praised, “I call this trick ‘Fish Out of Water.’”

*Tss—*

A stream of nosebleeds suddenly spurted out of Ma Bangde's left nostril,

The bright red nosebleed drew an arc in the air and accurately hit the teacup on the table.

Miss Chai exclaimed, “Is this okay too?”

Li Ang pressed Ma Bangde down hard and reached out to wipe the cold sweat on his forehead, “Should be fine...”

*Tss—*

A colorless, transparent liquid flowed out of Ma Bangde’s right nostril, flowing down his mouth to his chin.

Miss Chai was stunned, “What is this? Snot?”

“Um...”

Li Ang squinted his eyes and observed for a while, “Oh, it’s okay, it’s not snot, it’s cerebrospinal fluid in the brain.”

“???!!!”

“Don't worry, about 500ml of cerebrospinal fluid is produced every day, which is about the same amount as a bottled Coke. It's okay to lose so little.”

Li Ang smiled heartily and gave a thumbs up, “By the way, I prefer Pepsi with less gas.”

“No one asked you that!”

Miss Chai deeply realized the feeling of a tight chrysanthemum and had no intention of arguing with Li Ang about whether Coke or Pepsi was better.

“Okay, the intracranial pressure has dropped almost.”

Li Ang nodded, raised his fingers slightly, and ordered all the mycelia to slowly withdraw from Ma Bangde's brain and release substances so that Ma Bangde could slowly wake up from his coma.

Li Ang shook his hands, and all the mycelia on his fingertips automatically fell off, fell to the ground, coiled into a ball, and were finally burned to ashes by Li Ang with a Swiss Army Knife 300 lighter.

When Ma Bangde woke up leisurely, he found himself lying on the table, his arm numb from being pressed by his head.

Li Ang sat opposite him across the table, sipping tea slowly and methodically, as if nothing had happened just now.

“Daozhang, I am...”

Ma Bangde supported the table with one hand and covered his forehead with the other, feeling dizzy and confused.

The last picture he could remember was when Daozhang Siemens shouted, "Taishang Laojun, hurry like a law, fix!"

Then he passed out.

Li Ang put down his teacup, smiled slightly, and said with an immortal air, "Your illness has been cured."

"Really? That's great!"

Ma Bangde let out a long breath, his heart filled with thousands of emotions.

He was just about to thank the other party again, but he felt something sticky on his nose. He扣ed it off and it was a piece of congealed nosebleed stuck to his left lip.

"Uh, this is..."

"You may have a fever and had a nosebleed just now."

"Oh, oh."

Ma Bangde nodded and扣ed it off again, and found that there was also a mass of semi-dried, transparent, viscous colloid sticking to his right lip. "Uh, what's this again..."

Li Ang said without changing his expression, "You may have a cold and had a runny nose just now."

"Oh, oh."

Ma Bangde nodded confusedly, reached out his sleeve to slightly cover his face, brushed away the nosebleeds and snot, and said in a muffled voice, "Daozhang's life-saving grace cannot be thanked with just words. I will definitely offer a generous gift and build a shrine for Daozhang in Goose City to express my gratitude..."

"A doctor has a benevolent heart. The magistrate does his best for the people of Goose City. How can I not save him?"

Li Ang said with a smile; "By the way, Magistrate, you have just recovered from a long illness. It is best not to go out for the next few days, stay at home and recuperate, sleep more and eat more to observe the curative effect."

Well, after losing so much cerebrospinal fluid at once, it's time to take a good rest, and also provide Li Ang with some experimental data on brain modification.
