What is the most poisonous gas in the world?
When everyone was confused by Shinra's sudden question, Shinra started to walk toward the group of Heavenly Wolves Fist calmly, which made all of them tense, filled with edginess and nervousness, as they knew nothing about what he planned to do.
Naturally, it was the same with the bodyguards of Katahara, especially when Shinra talked about poisonous gas.
Did Shinra keep a poisonous gas?
Still, Katahara, Erioh, Mikoto, Shion, Tomoko, Karura, and those strong, who stayed in this place, continued to watch Shinra with fascination and even an obsession.
"On our planet, which gas is the most harmful to our bodies?"
When Shinra asked that question, his posture was extremely relaxed, as if he was taking a stroll in the park instead of facing the legendary fighters of Taiwan.
"DON'T LET YOUR GUARD DOWN, EVERYONE!"
Everyone in the Heavenly Wolves was nervous, yet the oldest, Cai, reminded everyone to be careful. Still, despite this, they showed both confusion and unsettled emotion as Shinra walked toward them calmly!
"Sarin gas and carbon dioxide are both toxic... hydrogen cyanide can also cause death..."
What is this posture?!
The more Shinra talked and walked, the more they felt this creepy feeling that came from an unseen terror.
"However, when someone dies under the effect of those gases..."
Nikaido continued to observe Shinra, who remained calm and tranquil, which only made him even more uneasy, as he had no idea what Shinra was about to do.
It was a new technique that was developed from the secret technique of the Heavenly Wolves Fist: Qinlong!
What would Shinra do?
The more they thought, the more they felt restless.
"Whether they became disoriented or suffocated... death only comes slowly... very slowly... like a gentle breeze..."
Then, Shinra suddenly appeared in front of Nikaido!
"ATTACK HIM, LORD!"
Nikaido, who was in a fighting stance, was at a loss when he saw Shinra in front of him in just a moment, yet when he was about to make his attack, Shinra's palm was in front of his nose, then—
"LOORRRRDDDDDDDDD!!!"
As all the members of the Heavenly Wolves Fist roared, Nikaido felt everything was cut off, blacked out, then he fell like a marionette whose strings were cut with a plop.
"....."
Everyone was at a loss, and when Shinra looked at the rest of the members of the Heavenly Wolves Fist, they all felt weak and somehow dropped their legs as they didn't dare to approach him.
What did Shinra do?
What was happening?
Why did Nikaido suddenly fall?
Did Shinra really release a poisonous gas?
If so, then would they be affected at this moment?
Everyone knew that while martial arts were powerful, a poisonous gas was still a powerful weapon!
Invisible yet deadly!
"Don't you know the answer? Let me answer you." Shinra looked at the members of the Heavenly Wolves Fist calmly and said, "The most toxic gas on our planet is oxygen."
"...oxygen?"
Did Shinra use oxygen?!
While everyone was dumbfounded and even at a loss, wondering how Shinra even thought of creating this technique, the origin of this technique came from the first step of the secret technique of the Heavenly Wolves First: Qinlong, Xu, who compressed air within his palms before releasing it all at once.
By compressing the air, he also gathered the air, so if that was the case, he could gather oxygen, too, right?
Then, with Sharingan, everything became smooth, and at the same time, Shinra also wondered whether he was also a genius at martial arts since it was so easy for him to master all the martial arts.
"Oxygen? Really?" Katahara was surprised, yet his voice was full of excitement.
"You can search me if you wish, but you will find nothing. The only poison I use is the one that we use to breathe all the time, and that is ordinary oxygen."
As everyone remained silent and confused, Shinra asked, "Do you need me to explain?"
"Can you?"
"Sure, it isn't like people can mimic it, either."
"..." Everyone.
"Thank you!"
Staring at Katahara, who was still playful despite watching how easy it was for him to take the life of people with ordinary oxygen, Shinra understood why this old man could become the undisputed chairman of the Kengan Association.
The proportion of oxygen in the air we all breathe is 21%." Like a lecturer in front of many students, Shinra started to explain, "As the proportions begin to decrease, little by little our bodies start to weaken. Dizziness, shivers, nausea, vomiting, and finally, loss of consciousness. Those are the symptoms you run into when the proportion of oxygen in the air is only 15%.
"But that's too slow and useless in a battle where the result must be determined by a fraction of a second.
"6%." Shinra showed his palm, causing everyone to tense up. "Once the proportion of oxygen in the air is below 6%, just one breath and it is guaranteed immediate loss of consciousness.
"No matter who they are, even the legendary, the strongest, or even a god, all of them will lose their consciousness in front of my technique."
Gulp!
This was a type of fighter that they had never seen before, and it made them tremble with horror as they knew that they couldn't defeat this technique.
Human beings are tough. Some can hold their breath for five minutes, but if they breathe a single breath of air with less than 6% oxygen, they will be in a total shutdown.
"It is an incontrovertible biological reality."
Walking toward another large tree, Shinra continued to talk, "After I saw that secret technique where your leader gathered air to release a blast, I thought of this error that happens to every human that I read in Shion's university, and I succeeded in creating this technique."
By then, all of them looked at Shion, who gave a nod. "He learned all the knowledge from my university that interested him."
"...." Everyone.
"I can contain in my palm air containing less than 6% oxygen and create a small vacuum on my palm."
Shinra placed his palm on the large tree and pulled his hand back as he said, "Take a good look."
BOOOOOOOOOOOOOOMMMMM!!!
Using a vacuum in his palm, the tree was blasted.
"...."
"Let's call it a Vacuum Hand."
Gulp!
Everyone looked at Shinra's hand, which gave birth to the most poisonous gas on Earth!
More dangerous than sarin gas or hydrogen cyanide, and with just one breath, it would light you up no matter who you were.
"Amazing! Amazing! Amazing!"
Clap! Clap! Clap!
Katahara clapped his hands excitedly like a child who saw a new toy, as Shinra looked at the rest of the members of the Heavenly Wolves.
"Do you all want to test it?"
"No! No! No!"
While they were sorry for Nikaido, their Lord, they didn't want to try to be hit by Shiran's Vacuum Hand, and without a doubt, the victor of this sparing battle was Shinra.
Yet, as Shinra easily won the victory, a certain someone within the Kure Clan had a beastly, gloomy grin as he was unable to contain the emotion in his heart.
