Asa left the settlement and returned to the forest on the other half of the island.

Robbing Anilu of a fruit, and returning one to him is already considered benevolent and righteous, and he does not have the slightest burden in his heart.

Now I can let go of all my burdens and work hard in the forest.

Daily exercise can not be put down, the body is also the future dependence, Asa tried to swing his fist, each punch with all his might, the fist wind led by the dead branches and leaves on the island clouds.

Sweat splashed everywhere, and he ignored it, completely indulging in the pleasure of the great power, allowing his clothes to be soaked with sweat.

"My current Thunder Fruit has only been developed to the initial stage, and if I want to continue to be strong, it will take time to polish it, what can I do to make it stronger?"

While exercising, Asa was thinking about other issues, and this physical exertion was not enough to distract him.

"Electricity can stimulate musculoskeletal cells and make the body stronger quickly, should I give it a try?"

He suddenly thought of this, and his eyes lit up, and he thought he could give it a try.

In his previous life, he liked to watch all kinds of anime, One Piece was his favorite, but there was an anime called Naruto that he also watched.

The thunder shadow inside is a powerful physical power with a family secret method, and this secret method is thunder and lightning!

As soon as he thought of this, he couldn't take it back, and Asa even stopped exercising on his hands.

"This method has to be tried, and it doesn't matter if it fails, but if it succeeds...... In the future, I can even wrestle with Kaido Whitebeard! His eyes lit up terrifyingly.

However, this method is very dangerous, and it can be life-threatening at any time, and it takes some time to explore.

Lei Ying's secret method is a family heirloom, and his ancestors must have spent a lot of time exploring it from generation to generation, which formed a unique strengthening secret method.

But Asa is different, Asa eats the thunder fruit, can control the thunder and lightning, he can accurately transmit the current size, in the fastest time to study this secret method, and over time, surpassing the thunder shadow is a sure thing.

......

The experiment was very dangerous, and Asa had to do it himself, and if he got out of control, he would face death.

For an ordinary person, the cause of electrocution death is generally that the current passing through the human body exceeds the safe value that the person can tolerate.

If the value is exceeded, the lungs will stop breathing, and the heart muscle will lose the ability to contract and beat, causing the heart to have ventricular fibrillation, the "blood pump" will not work, and the blood circulation throughout the body will stop.

After the blood circulation stops, it causes a lack of oxygen in the cell tissue, and within 10~15 seconds, the person loses consciousness, and after a few minutes, the human nerve cells begin to be paralyzed, and then cause death.

These are common sense questions, and Asa was a welder in his previous life and often worked with electricity, so he knew everything clearly.

The severity of human electric shock injury is directly related to the magnitude of the current, voltage, resistance, length of time, current path, and human physical condition through the human body.

When the current passing through the human body is 1 milliampere, that is, one thousandth of an ampere, the person will have a pinprick feeling, and at 10 milliamperes, the person will feel unbearable, and the body will have some reactions.

At 20 milliamps, the human muscles will contract, and if the power is continued at this time, then it will cause death, and at more than 50 milliamps, even if the power is on for a short time, it is also life-threatening.

Asa's current physical fitness is no longer human, in short, superhuman, and the current that he can withstand with a strong physique will inevitably increase, so he can slightly increase the current strength at the beginning of the experiment.

But don't forget, it's not just the electric current that is harmful to the body, it's also the voltage!

The higher the voltage, the more dangerous it is, the average person can withstand the safety voltage of 36 volts and below, if it exceeds 36 volts, there is a risk of electrocution.

And the longer the electric shock, the greater the danger. Because when the person is unable to get rid of the power supply, the ability of the muscles to contract will quickly decrease, and then heart failure, suffocation, coma shock, and even death.

At this point, Asa is not worried at all, as the master of thunder and lightning, he can control the thunder and lightning as he wants, and he can stop as soon as he feels uncomfortable.

The Thunder Fruit has a trick called electrotherapy, which can stimulate the heart through electricity and bring people back from the dead, Anilu can develop this metamorphosis ability, it makes no sense that Asa can't use electricity to stimulate muscles and strengthen the body?

He found a place to sit down, carefully mobilized the thunder and lightning, and kept his body from entering the elementalization, and began to try little by little.

Of course, in the first experiment, Asa did not dare to use it directly on his body, so he concentrated the transmitted electricity on his little finger, and everything except the little finger was blocked, so that the current could not reach the body.

It's just a small thumb, if it is scrapped and cut off directly, it will not affect the combat effectiveness, there is a way to recover it in the sea, but it will not work on the body, and the person with organ and tissue damage is almost on the verge of burping, and there is no life to go to the doctor for treatment at that time.

Little by little, the current passed, gradually intensifying, and Asa carefully felt the change in his little finger......

......

Time flies, a month later.

"Finally it worked!" Asa, who was sitting on a thick branch, almost jumped up in excitement.

After a month of testing, he can clearly feel that his left little finger is stronger than his right little finger, not only in strength, but also in flexibility and flexibility.

"Haha! Finally, I can safely strengthen it with electricity, and the name of Kaido's strongest creature in the sea, land and air is better for me! Asa looked excited.

For a month, the current and voltage have been continuously strengthened, and the little finger of the left hand was almost burned to char because of an accident.

Now that the experiment is successful, the body is strengthened under the current all the time, and sooner or later it can be strengthened to the terrifying level of fist town mountains and rivers and kicking the four seas.

"Zizi!"

The sound of the electrical chirping was inaudible, and under Asa's control, it flowed to every corner of his body, even the bones, and only the fragile internal organs were isolated.

He doesn't dare to joke about the viscera now, a bad one will die, but Asa believes that sooner or later, even the viscera can be strengthened, and then there will be no dead ends in all directions, and a superman without the slightest weakness will be born.

"Hmm~"

The skin, muscles, and bones were slowly getting stronger, and the tingling sensation made Asa moan involuntarily, and he looked around, a little ashamed, but fortunately there was no one nearby, otherwise he would have killed people.

This feeling is more comfortable than soaking in the hot springs, the whole body is crispy and numb, and like the gentle massage of a girl, Asa let go of shame and quietly enjoyed.

PS: The section on current and voltage is taken from Baidu. By the way, I ask for tickets and collections, and thank you.

has been restored and updated, and the protagonist has also gotten the Thunder Fruit, and the next plot is to go to the sea to let loose the waves.
