Z warriors' expressions also changed, including Goku, Vegeta.
Other audiences didn't understand what happened, but they knew clearly.
It was Ki and a way of using Ki they didn't even know about; in just a split second, an invisible white huge palm separated from Eero's body, stopped Genih's attack. Then the next instant, a similar invisible huge fist condensed from his Ki, separated from his body, blasted Genih's chest.
It looks simple, but such a fine control of Ki; and Ki shape changing they haven't seen or thought before. Except some disk or ball shape attacks they can't change Ki into any other forms,
"Gohan, I didn't expect your friend to be a martial art genius," Krillin commented solemnly. As a Shaolin disciple, he knows how much talent is required to control the Ki to such a degree; even his and Goku's master can't control it to such a degree.
"He he he," Gohan laughed awkwardly, 'I found it myself just now?' thought to himself. Looking at Eero walking off the stage.
"Not bad," Vegeta nodded gave a compliment with an intrigued expression.
"This guy is interesting; I hope his strength is also strong, so I can challenge him," Goku spoke with a smile.
Eero left the stage; in the next stage, he similarly defeated those arrogant competitors, and other Z warriors also fought all the way to the final round.
...
In the midst of the competition, Goku and the Z Fighters meet an unusual pair of beings who go by the name Shin and Kibito.
Eero was looking at them from far away, 'Here they are Supreme Kai and his subordinate Kibito. Well, this Dragon Ball world ranking is really strange; a Supreme Kai life is linked with God of Destruction. If one dies, the other will also die; also, these Supreme Kai are really a bunch of weaklings compared to the God of Destruction.'
Shin turned and glanced at Eero, feeling his gaze, then turned around and left with Kibito.
'It's getting interesting; soon Majin Boo will be revived,' Eero thought to himself.
The final eight versus list was also announced.
1. Krillin vs. Pintar
2. Piccolo vs. Shin
3. Eero vs. Spopovich
4. Gohan vs. Kibito
5. Mr. Satan vs. Android 18
6. Goku vs. Vegeta
7. Mighty Mask vs. Yamu
8. Vidal vs. Killa
Eero was looking at the list thoughtfully, 'It seems my arrival changed the history of the competition. Videl reached the last place; will she still be seriously injured near death similar to the original.'
Looking at Spopovich's name in front of his name, Eero muttered thoughtfully, "This guy is one of the antagonists along with Yamu; he was the one who beat Videl half dead."
Soon the competition started. Vegeta is very excited at being matched with Goku, who is equally interested.
Krillin comes out victorious from his match with Pintar.
Piccolo is matched against the mysterious Shin who reveals his true identity. Seemingly terrified, Piccolo withdraws from the match, telling Goku and the others that he believes Shin is actually the Supreme Kai, which shocks everyone because the Supreme Kai was thought to be a myth.
Eero was speechlessly looking at everything progressing in the original direction; he can't change anything, his strength is not enough, or he would have already changed the history.
He is just going with the flow. Soon it was his turn against Spopovich. Eero appeared on stage calmly, looking at muscular Spopovich in front.
"I know your trick, but your Ki can't break through my Ki defense," Spopovich spoke with an evil expression on his face, looking at Eero.
"Well, I will try to make you feel painful," Eero replied calmly, walked toward him, expanded his domain in just the stage area.
Domain x512!
Instantly the expression and body of Spopovich froze, just moving negligibly mm by mm. Eero appeared beside him, raised his hand, flicked his finger lightly on his chest.
A wave spread through his body from the chest, scattering through all his body.
Domain disappeared.
"Ahhhhhhhhh," a horrible cry spread around. The audiences were shocked looking at Eero, who instantly flickered and appeared in front of Spopovich. Spopovich is kneeling on the stage, grabbing his chest and crying horribly, as if feeling extreme pain.
"Ooh, I forgot to tell you one thing more, the tougher your Ki layer, the more painful you will feel. When the 500-fold kinetic force travels through your body, Ki can save you from instant external attacks, not from the constant internal damage you experience,"
Eero reminded, looking at Spopovich, still crying horribly.
'This guy will cry like this for a few seconds probably. The kinetic force is traveling through his body at 500-fold lower speed; he feels like in hell this time. After this, his whole body will freeze; every muscle will cramp, cells will oscillate at high frequency, a lot of cells will be destroyed, even bones will be filled with small cracks.'
Eero was looking at him expressionlessly. After a few seconds, Spopovich's eyeballs turned, his muscles contracted veins bulged, and he stiffly fell on the stage similar to a wood piece.
"What happened? What has he done?" The audiences were extremely puzzled looking at Eero and Spopovich lying on the stage with visible veins and contracted muscles.
Probably muscle cramps happened on every muscle of his body, but no one understood his situation except Eero.
'It seems this experiment is successful; I can also slow down the speed of my attack damage while increasing their powers, just like now. I used kinetic force attack using pure physical strength; power increased by 512 times in domain, and speed of kinetic force scattering slowed down by me instead,' Eero thought to himself, walked off the stage calmly, leaving confused and scratching audience.
Goku and Vegeta both became thoughtful, looking at Eero. 'How did he do it? Is it some kind of special talent?'
Eero appeared in the rest area, feeling some gazes, glanced in that direction. Looking at all Z warriors looking at him curiously, he smiled at them, looking at Goku smiling at him back, 'I wonder what kind of effect my domain will have on the ultra instinct of Goku.'
"It seems I should also try to learn the Ultra Instinct; it is a perfect match for my domain and my powers." Eero muttered thoughtfully,
'Probably after upgrading my senses skill to max, I will achieve Ultra Instinct after merging senses with instinct. That's why I was always heightening my senses.'
'According to my analysis, the first criterion of Ultra Instinct is a calm mind, which I already achieved, and the second is extreme instinct, also achieved.'
'Finally, the third criteria is extreme senses. I will probably achieve it soon,' Eero thought to himself.
