Billy had studied that mystic art on his way from Celestial City to Endless City.
Theoretically, there were no major issues, just waiting for practical application.
However, he had two feelings about it.
Firstly, this mystic art was not simple as it seemed. If he could truly master it, it could become one of his trump cards.
Secondly, he vaguely felt that practicing this mystic art wouldn’t be easy, so he specifically entered the Nine Dragons Cauldron Space to have White Feather and Purple Spirit keep an eye on him.
“Billy, don’t scare me. If it’s dangerous, don’t practice it!” Purple Spirit said after a moment of hesitation.
“I should be fine. Let me try first!” Billy smiled.
“Be careful then!” Purple Spirit replied.
“Okay!” Billy nodded.
He then sat down cross-legged.
The first part of the mystic art was similar to what he had practiced before. In less than a quarter of an hour, he felt the blood in his veins start to become active.
As time passed, the activity of his blood increased, as if it were boiling.
At this moment, Billy felt increasingly uncomfortable. The blood vessels in his body expanded to twice their usual size, and veins bulged on his forehead.
After a while, Billy once again experienced the long-lost feeling of blood flowing backward and the sensation of being gnawed by thousands of ants. His expression twisted slightly, and his body trembled.
“Billy, stop if you can’t go on!” Seeing Billy’s condition, Purple Spirit’s face showed a trace of worry.
“It’s okay, I can hold on a bit longer!” Billy gritted his teeth and replied.
“Billy, don’t push yourself if you can’t!” White Feather also spoke up.
“Okay!” Billy responded.
After another half an hour, an extremely violent aura exploded from Billy’s body, followed by a burst of blood-red mist.
White Feather and Purple Spirit were thrown seven or eight kilometers away without any resistance. Blood trickled from the corner of White Feather’s mouth.
At the same time, the mist spread instantly, turning everything within tens of kilometers blood-red, blocking out the sun.
White Feather and Purple Spirit felt as if they were in a sea of blood. An extremely terrifying pressure filled the air, making Purple Spirit shiver involuntarily.
At this moment, Billy’s pupils had turned crimson, and his expression was extremely twisted.
His entire skin turned blood-red like a blood man, his body trembling uncontrollably, and his aura continued to rise.
Meanwhile, White Feather, who was thousands of meters away, also showed a twisted expression with pain between her brows.
“White Feather, what’s wrong?” Purple Spirit couldn’t help but ask.
“I feel like my blood vessels are going to burst!” White Feather gritted her teeth and replied, “It must be influenced by Billy’s bloodline!”
“Really?” Purple Spirit was stunned for a moment. She didn’t have a bloodline, so she didn’t feel anything.
After a brief pause, she continued, “White Feather, you should adjust your breathing. I’ll go ask Billy to stop.”
She quickly flew towards Billy. “Billy, stop now…”
“Purple Spirit, be careful!” White Feather shouted loudly after a moment of hesitation.
Before she could finish her sentence, Purple Spirit was blown away like a leaf.
She flew out more than ten kilometers before barely stopping and fell to the ground weakly, with only two or three tenths of her strength left.
“Purple Spirit, are you okay?” White Feather gritted her teeth and ran over quickly.
“I’m… I’m fine…” Purple Spirit struggled to get up from the ground.
After a brief pause, she continued, “White Feather… we need to find a way to make Billy stop. I feel like he’s about to go berserk. If he doesn’t stop now, something bad will happen…”
“You rest for a bit. I’ll try!” White Feather gritted her teeth and flew towards Billy with her wings flapping.
“White Feather, come back! It’s dangerous…” Purple Spirit shouted loudly after a moment of hesitation.
“It’s okay. I’ll try!” White Feather replied.
As expected, after a loud bang, White Feather was blown away like Purple Spirit and fell heavily more than ten kilometers away.
Due to the influence of Billy’s bloodline, her condition was even worse than Purple Spirit’s after just one encounter.
Her blood vessels seemed about to burst out of her body, and a large amount of blood gushed from her mouth. She lay on the ground for a long time without being able to get up.
“White Feather, are you okay?” Purple Spirit came over.
“I’m… I’m fine…” White Feather shook her head with difficulty.
At this moment, Billy had already flown to within a few hundred meters of them, looking like a bloodthirsty demon.
In his current state, even an opponent at the early stage of the Controlled Kun Realm would likely be defeated in one move.
“Billy, stop now!” Purple Spirit shouted loudly.
“You two… leave the Nine Dragons Cauldron Space quickly…” Billy said with difficulty. “I… I can’t control my body…”
“What about you?” Purple Spirit shouted loudly after a moment of hesitation. “If you continue like this, won’t you go berserk?”
“Don’t worry about me… just leave here quickly… otherwise I won’t be able to control myself and might attack you…” Billy continued to respond.
From his expression, it was clear that he was enduring unbearable pain.
His eyes were crimson red, veins bulged on his forehead, his teeth were clenched tightly, and his whole body was trembling.
“No way. If we leave, you’ll be in even more danger!” White Feather said after a brief pause.
“Go… go quickly…” Billy shouted again with difficulty.
“If you don’t have the strength, don’t mess with your bloodline!” At this moment, a man’s voice sounded. “If you keep messing around like this, sooner or later you’ll play yourself to death!”
As the voice fell, a man in white clothes appeared in the air-it was the white-clothed hero.
“Master!” White Feather shouted when she saw the white-clothed man.
“Mr. White, you’re just in time. Please save Billy!” Purple Spirit also shouted.
As they spoke, the white-clothed man raised his hand and sent several gusts of wind into Billy’s body.
Billy spat out a large mouthful of blood into the sky and flew back more than ten kilometers before falling heavily to the ground and fainting with his eyes rolled back.
At the same time, the blood-red mist in the air disappeared instantly without a trace. Billy’s body quickly returned to normal, and peace was restored in the Nine Dragons Cauldron Space.
Billy didn’t know how long he had been unconscious when he slowly woke up. He opened his eyes and saw that he was still in the Nine Dragons Cauldron Space.
“Billy, you’re awake?” White Feather and Purple Spirit said simultaneously from beside him.
“How long was I unconscious?” Billy asked as he rubbed his aching head.
“Exactly one day!” Purple Spirit replied.
“So long?” Billy was stunned for a moment before continuing to ask, “Did the Mr. White leave?”
He could remember what happened before he fainted and knew that it was the white-clothed man who suppressed his bloodline; otherwise, he didn’t know what would have happened.
“Yes!” White Feather nodded.
“Did he say why I experienced that situation?” Billy continued to ask.
“He did!” Purple Spirit nodded seriously and said. “Mr. White looked at your mystic art for practicing your bloodline and said it was a dangerous product that could kill people!”
