The moment after power is turned on.

All kinds of strange and colorful shadows appeared throughout the iron gate room.

The recruits didn't even have time to look around before they were stimulated by the powerful current on the iron chair and forced into a ghostly state.

For a while.

The guardian spirit of demons and ghosts poured into the heart, bursting out with several dazzling lights.

No wonder the demon training ground in the martial arts hall is located underground.

Just because so many new recruits undergo ghost-humanization training every day, there is no telling how much commotion there will be.

The first time Du Huaishan felt the electric stimulation, his whole body was so painful that he became stiff.

After pouring the four-cornered demon into the heart.

Instantly.

The pupils of Du Huaishan's eyes began to glow black and red, and the muscles all over his body squirmed and expanded.

Centipede-shaped green veins are wrapped around the forearm and forehead.

One percent!

Compared to the pain of sending souls for the first time.

After Chang Sui'an's guidance, Du Huaishan consciously controlled the progress of the fusion of demon power this time.

really.

I don’t know whether it’s due to less energy from demons and ghosts, or the effect of Yingzhou Army’s special medicinal solution and current stimulation.

The negative state of his tinnitus has been reduced a lot, and he has more energy to think.

Boom, boom, boom!

Du Huaishan could clearly detect that the heart in his body was beating very hard, far exceeding the highest human heart rate of more than 200 beats/minute.

He remembered that it was taught in "Kinematics" in college.

The nutrients and oxygen required by the body mainly rely on blood transportation pumped by the heart.

If the heart can pump a lot of blood at one breath or the pumping frequency is accelerated, the body's exercise ability will be greatly improved!

In professional terms, the former is called stroke volume, the latter is called heart rate, and the two combined are called CO, which is cardiac output.

Professional athletes have stronger physical fitness than ordinary people precisely because their CO levels are higher.

However, human heart reserve capacity is limited, and cardiac output cannot increase indefinitely.

Elevating the heart rate within a certain range can increase CO. However, when the heart rate is too fast, the time for the heart to pump from the veins is too short, so the amount of blood pumped is insufficient. Although the pumping speed is accelerated, the amount of blood pumped out each time is not enough.

But it's getting less.

This critical value is 150 times/min.

But Du Huaishan's current heart rate is at least nearly twice the critical value. Instead of getting weaker, CO has become stronger.

The power of demons and ghosts increased his pumping ability!

This is equivalent to.

A car originally had a 2.0T four-cylinder engine, but it was replaced with a 3.0T six-cylinder engine.

Not just the heart.

Neuronal responses, lungs, vital capacity, lung function, and even the oxygen-carrying capacity of red blood cells are all enhanced.

It can be said that "a single move affects the whole body"!

As Du Huaishan increased the degree of fusion, under the stimulation of the electric current, he felt that the four-cornered ghost guardian spirits hovering around his heart were constantly absorbing the energy of the Yingzhou Army's mysterious liquid.

But a small part of this energy flows into the brain along the blood vessels and finally disappears.

In the ghost-human state.

Every muscle cell in his body is filling, expanding, and finally dividing!

React to the muscle surface.

The arm muscles tear and swell at a speed visible to the naked eye.

But the tinnitus was obviously stronger, and various noisy noises began to interfere with Du Huaishan's consciousness. Pain appeared in his brain, and something seemed to break out of his forehead. They were two one-inch-long, black-red sharp corners!

The heart pumps wildly.

The blood in the veins is like poured copper water, gurgling and pounding against the whole body.

He gritted his teeth and relied on the will he had tempered in his previous life to endure the interference of demonic energy on his consciousness.

Chang Sui'an stood in front of more than fifty ghost-human recruits, watching the degree of alienation in their bodies.

It's not just him.

Soldiers wearing masks are also observing and adjusting the current at any time according to different conditions.

The current in Duhuai Mountain continued to increase.

Muscle and nerve pain caused by strong stimulation can, to a certain extent, disperse the interference of demonic energy.

"ah--!!"

Suddenly, one of the recruits seemed to be unable to bear it any longer. He screamed and fell into a coma.

The white-masked soldier immediately cut off his power supply.

Next, the unconscious recruits fell down one after another like dominoes, leaving only a few who were still holding on.

Chang Sui'an turned his pupils and recorded the appearance of these people.

People with stronger physical endurance and stronger will often go further on the road to controlling the power of demons and ghosts.

"Huaishan, I can't do it anymore..."

Guo Tingyu gritted his teeth, struggled to spit out these words, and then passed out.

at last.

Of the more than fifty recruits present, only Du Huaishan and the thin and muscular female soldier with coiled hair remained.

The current continued to increase, Du Huaishan's body began to tremble and twitch, the veins on his face spread, and gradually became ferocious, the black and red devil's horns further grew, and even black mist filled the air!

Two percent!!

"stop!"

Chang Sui'an looked at the time and shouted to stop.

Buzz.

The masked soldier immediately pressed the red button and all electric chairs were powered on and off.

"Huh..."

"Ah…"

Du Huaishan dissipated the power of the demon and ghost, and the alienated state disappeared. He was breathing heavily, but he heard someone breathing violently not far away from him.

The two looked at each other.

Is it him/her?

The female soldier with coiled hair looked even more embarrassed, with messy hair scattered in front of her forehead, but it still couldn't cover her cold blue-gray pupils.

"take a break."

Chang Sui'an only said four words and said no more.

Because at this moment, his heart was already thundering and lightning was exploding like fire.

Du Huaishan only trained the power of demons and ghosts for the first time, and the fusion degree exceeded 2%!

He didn't know the condition of each recruit, but Du Huaishan was different. He clearly understood everything that happened to this boy on the Xintun battlefield.

Du Huaishan just finished Qiling!

The red marrow liquid that Chang Sui'an gave to each of the recruits was fixed. How much he could absorb through electrical stimulation depended on his own fusion talent.

It sucked 2% at once, this speed is amazing!

What Lao Chen said is right.

This kid is really a genius in terms of integrating the power of demons and ghosts!

he.

Born to fight!

a long time.

The recruits woke up one after another and found that the handcuffs and shackles on their bodies had long been opened, and there was a hot potato in front of them.

Gu Gu.

Not to mention, after this "torture", I was really hungry.

While everyone was eating, Chang Sui'an continued to speak: "The red marrow liquid contains a lot of energy, which is enough for normal people to digest it for a week. From now on, except for rest days, I will come here every day after combat training for fusion stimulation."

"Report!"

A recruit munching potatoes raised his hand.

"speak."

"Instructor Chang, does the martial arts hall only plan to train new recruits like us from now on?"

"No. Any recruit who performs well in regular training will be given the opportunity to have a magical spirit. There will be more and more people in this room in the future, but there is no need to worry, the red marrow liquid is enough."
Chapter completed!
