My health recovery is incredibly fast.

Xia Zuo was momentarily stunned.

Both my previous life and this current world have conducted in-depth research on the human brain.

The two sides reached an agreement on one point:

The left brain controls logical thinking (rationality), while the right brain tends to focus on artistic thinking (emotionality).

Within the alchemical school, this conclusion stems from numerous live experiments conducted at the end of the previous era—the Year of Bloodshed and Turmoil—making its credibility nearly 100%.

Tyson replaced his right brain with an alchemical brain. Does this mean that he abandoned artistic thinking, allowing pure rationality to dominate his entire brain, and turning himself into an emotionless alchemical research machine?

This is insane...

Xia Zuo swallowed.

Mars gave him a strange look, followed his gaze to his mentor's alchemical brain, and then nodded in understanding.

Anyone who sees Master Tyson for the first time reacts like this, and Mars himself was no exception.

"Is this the underwater bullet you invented?" Master Tyson adjusted the magnification of his glasses, and the two glass plates bulged forward, turning into two glass cones.

Two red rays shot out from the top of the glass cone and landed on the underwater bullet, scanning it from top to bottom.

"Antonio-type threaded alloy, hardness level 55, 9x150mm, flat bullet, rounded concave..." Master Tyson calmly stated the data he had scanned, "It's also enchanted with a water pressure channeling array that allows for rapid adjustment of power. Bullets with this design will generate bubbles when flying rapidly underwater..."

Although Tyson was Mars' mentor, this was not a reason for Mars to reveal the group's secrets.

In fact, Mars remained silent about the killing principle of underwater bullets and never mentioned it to anyone, including his mentor.

Master Tyson immediately saw the key to underwater bullets, entirely thanks to his mastery of macroscopic creation. Don't forget, this is alchemy based on mechanics, which involves aerodynamics.

"Could these bubbles be the source of the underwater bullet's power?" Master Tyson looked at Hillenburg, pondered briefly, and the energy light in his energy circuit flashed rapidly. "Pressure difference, right? There is a clear pressure difference between the pressure inside these bubbles and the water pressure."

“That’s right, Master.” Hillenburg nodded with a smile, then reached out and patted Shazo on the shoulder. “It was Shazo who discovered supercavitation.”

Xia Zuo humbly said, "I found the answer in the team leader's research notes. I can't make underwater bullets by myself. I just came up with a concept."

Master Tyson crossed his arms. "Not bad, lad. I heard Mars mentioned you, a Starry Night Academy student obsessed with alchemy. I like alchemists with simple minds."

He shoved the alchemical glasses back into his mechanical face. "I want to experience the power of underwater bullets."

Hillenburg nodded, picked up the underwater sniper rifle and placed it in front of the other person, "You can fire at any time, Master. We have prepared the site."

Master Tyson, however, shook his head and said, "It's not me shooting, it's shooting at me. I want to feel the pressure difference."

Xia Zuo was taken aback, and he and Hillenburg looked at each other in bewilderment.

Mars, who knew his mentor's personality and the alchemical bionic human body best, said from the side, "Master Tyson is fine; he can protect himself in the face of pressure differences."

"Oh... okay, I'll arrange it right away." Hillenburg adjusted his glasses, put down his underwater sniper rifle, walked to the control panel, and spoke to his team members in the combat training area through the coral megaphone:

"Huberon, come back now. You'll be controlling the battle puppets later. Danielle, Laurie, recall the monsters..."

Upon hearing the group leader's words, the group members knew that the situation had changed, but none of them asked any questions. They all followed the group leader's instructions and took action.

“Master Tyson, I need to confirm, are you planning to use your body to withstand the force of underwater bullets?” Hillenburg asked uncertainly. “Do you need me to prepare a combat puppet for you?”

“You’ve understood correctly, Hillenburg,” Master Tyson said calmly.

"I don't plan to wear a diving suit, nor will I use the combat puppet's sensory system to convey pain."

"You may not know this, but I've made some adjustments to my sensory system so that it can visually present a series of data while transmitting feelings of pressure or pain. You'll understand the significance of this later, so don't worry about my safety."

“Yes, Master.” Hillenburg nodded expectantly.

Huberon returned via the diving room.

Hillenburg stepped forward, gave him a few instructions, and then had him lie down on the soft sofa to synchronize with his battle puppet.

"Everything is ready." Hillenburg led Master Tyson into the diving room and watched him step into the sea.

A hazy light traveled across Master Tyson's body before disappearing into it.

This is the radiance of the water pressure channeling spell.

Master Tyson, with his alchemical brain's computational abilities, dynamically adjusted the power of his spells, always keeping the surrounding pressure at around one atmosphere.

This exquisite control ignited Xia Zuo's interest in the alchemical brain, and he even considered installing one on himself...

“Mars.” Xia Zuo pulled his senior aside, staring at Master Tyson swimming in the water, and asked him:

"Did your advisor have the right side of his brain removed? Will that affect his emotional system?"

Mars covered his mouth and said in a low voice:

"It's not what you think, Shazo. Master Tyson suffered a serious illness when he was young, which caused significant brain atrophy. His brain was originally only half the size of a normal person's."

"After undergoing treatment, he had his original brain implanted in his left brain and then had his self-developed alchemical brain implanted in his right brain."

"Truly admirable," Xia Zuo exclaimed sincerely.

Despite his congenital deficiencies, Tyson became an outer temple master and used alchemical methods to heal himself; his life story is truly legendary.

Xia Zuo thought for a moment and then asked, "Among the masters in the outer hall, how many people have installed alchemical brains in themselves?"

“Hmm…” Mars recalled, “This alchemical bionic device needs to occupy part of the intracranial space. I don’t remember many people having an alchemical brain installed.”

Does an alchemical brain interfere with meditation and contemplation?

"No." Mars shook his head.

"My advisor said that it would be better to call this a 'Logical Thinking Enhancement Device'."

"Its functions are limited and it is far from being a real human brain."

"Besides helping the host perform large number calculations and quick calculations, it can at most be paired with some alchemical bionic systems to make research easier. For example, the visual system with an identification magic array is the ruby ​​in his right eye."

"Sounds...quite convenient..." Xia Zuo figured that with the help of his cheat system, he didn't need an alchemical brain with similar functions for the time being...but that didn't stop him from equipping his blood element servant with one.

"Is there a logic enhancement device that doesn't need to be installed inside the brain?" Xia Zuo asked.

“That’s an alchemical item enchanted with the [Logic Enhancement] spell circle,” Mars said. “Logic Enhancement is a blessing spell, which can only be learned by high-ranking mages. You can learn this spell yourself after you become a high-ranking mage, or find an enchanting master to enchant it on your alchemical item.”

"Oh, I see." Xia Zuo felt a sense of anticipation. "I'll have to study this carefully once I become a high-level mage."

As the two were talking, Master Tyson's experiment was about to begin.

He swam to a spot 50 meters directly in front of the combat puppet and stood still.

Huberon successfully synchronized with the combat puppet, unlocked the gun holster on the puppet's back, and pointed his underwater sniper rifle at Master Tyson not far away.

"Huberon, check the delay time for reducing the power of the magic circle to ensure that the supercavitation hits Master Tyson head-on," Hillenburg said at the control panel.

"Check complete, team leader. Ready to fire at any time," Huberon replied.

"Alright, countdown 5 seconds to fire the underwater bullet."

"5, 4, 3, 2, 1, launch!"

"Bang!" The underwater bullet was fired.

"Whoosh~" The bullet trailed the bubbles with a strange sound.

"Thump!" The underwater bullet struck Master Tyson squarely in the chest. A trail of bubbles enveloped his figure, mixing with the turbulent seawater and obscuring everyone's view.

The bubbles dissipated, and the sand and dust settled.

Master Tyson reappeared unharmed.

"Wow...did he block it with his alchemical body?" Xia Zuo exclaimed, scratching the back of his head. "I didn't see any magical light..."

“Yes, that’s right,” Mars said calmly. “Master Tyson used Mimar alloy to create a skin-friendly armor plate, which was implanted under the skin to replace part of the fat layer. You should know that Mimar alloy has a hardness level of over 150 and also has extremely high toughness. It is one of the rarest alloys.”

Xia Zuo opened his mouth, wanting to use the word "Holy shit!" to express his current feelings, but he swallowed this classic phrase from his previous life...

Mimar alloy is typically sold in thin sheets, and the price per square centimeter exceeds 1 federal citizen credits.

To fill your entire body with this stuff would cost at least a billion...

You get what you pay for.

Thanks to the Mimar alloy implanted under his skin, Master Tyson can withstand underwater bullet fire without any problem.

After taking a shot, he raised his hand to signal Humbert to wait.

He bent down, rummaged through the sand, found the underwater bullet bent at a right angle, scanned it with the ruby ​​in his eye, and then gave Huberon the order to continue firing.

"Bang bang bang..."

One underwater bullet after another emerged from the gun barrel, struck Master Tyson's chest, and then bounced into the sand bed.

After this series of experiments, Huberon fired at least a hundred shots, but Master Tyson remained calm and composed.

“Hillenberger, I have some ideas about what you wanted to ask,” Master Tyson said directly as he returned to the alchemy room.

"As you can see, the alloy can stop underwater bullets and supercavitation, but the hardness level needs to be at least 120."

"No research team would equip a combat golem with such good protective gear; it would be a pure waste."

"But they can use another method to deal with underwater bullets."

Master Tyson raised his right hand, and an arc of electricity shot out from his index finger and thumb. The arc of light lingered on his fingertip, as calm and steady as a well-behaved baby.

Fire energy and wind energy resonate to generate electric energy.

This is very basic knowledge about elements.

In the field of alchemy, a considerable number of alchemical tools or devices are powered by electricity.

However, because this energy is too active and has a relatively large destructive power, accidental incidents can easily result in death. Therefore, unless it is absolutely necessary, electricity will not be used as the primary energy source.

The alchemical school also studied electricity and discovered the existence of magnetic fields, positive and negative poles, and conductivity.

The alchemists called the property of being able to conduct electricity or possess magnetism "electric affinity".

The positive and negative electrodes are called the anode and cathode, respectively.

The term "magnetic field" is consistent with the scientific terminology used in science.

The alchemical school's research into electricity stopped there.

Just like their exploration of kinetic energy, the alchemical school's research on electrical and kinetic energy was far less in-depth than that of the previous generation of Shazo.

"I saw some metallic materials with an electrical affinity inside the bent underwater bullet," Tyson said.

"Their proportion is not high."

"The overall electric affinity of the underwater bullet is also insufficient to make it susceptible to electromagnetic influences."
