Mortal: I became invincible after becoming sworn brothers with Han Li.

"Thump!"

With a loud crash, Wang Chan's figure fell heavily to the ground like a falling goose, revealing a gaping hole in the blood cloud.

A glint of inspiration flashed in Li Yunfan's eyes, and he immediately increased the speed of the Cloud Piercing Boat to the maximum, transforming it into a white light and rushing out through the gap, continuing to fly into the distance without pausing at all.

Under Dong Xuan'er's control, the giant hammer talisman transformed into a golden light and followed closely behind.

"Damn you! I'm going to kill you!!"

As Wang Chan roared, he soared into the blood cloud once more, riding it to chase after Li Yunfan.

His clothes were disheveled, and there was a trace of blood at the corner of his mouth, indicating that he had suffered some injury.

It turned out that just as the sledgehammer was about to smash down on his head, he quickly took out a bead from his storage bag and unleashed it.

It was thanks to the bead that he was able to dodge the hammer's attack. However, even so, the clash of spiritual energy between the two sides still injured Wang Chan's internal organs. His spiritual energy stagnated, and he fell from the sky.

Standing amidst the blood-red clouds, Wang Chan's face was contorted, his eyes were bloodshot, and his entire body exuded a terrifying killing intent.

As the young master of the Ghost Spirit Sect, when had he ever suffered such humiliation, being forcibly knocked down from the sky to the ground!

With his cultivation level and the Blood Spirit Technique, he could have remained undefeated even if he was no match for two Foundation Establishment cultivators working together, thanks to the Blood Cloud. However, due to a moment of carelessness, he exposed himself, allowing his opponents to catch him off guard with their talisman treasures.

However, now that he knows all of the opponent's methods, even if the talisman still has some power, it can no longer harm him.

Li Yunfan glanced back at the surging, chasing blood cloud and couldn't help but sigh inwardly. He knew that as the young master of the Ghost Spirit Sect, the other party must have many life-saving treasures, but he didn't expect that even in that extreme moment, he still couldn't seriously injure the other party.

He then glanced at Dong Xuan'er, whose face was somewhat pale, and knew that it would be difficult for her to launch another talisman attack. He couldn't help but frown.

"It seems we have no choice but to try using the Purple Nether Heart Flame!"

After thinking it over, he immediately sent a telepathic message to Dong Xuan'er, asking her to channel spiritual energy into the Cloud Piercing Boat, while he retreated to the back to cast a spell to block the blood clouds.

He lowered his eyes, concentrating intently on circulating his energy, then clasped his hands together and gently pulled, and a firebird appeared in front of his chest, as he once again unleashed the Fire Spirit Technique.

However, upon closer inspection, one will notice that the firebird condensed this time is somewhat different in color from the previous firebird. Its red body is tinged with purple, and it faintly exudes a dangerous aura.

After the firebirds took shape, Li Yunfan looked up at the blood cloud, then waved his hands suddenly, and more than ten firebirds appeared in front of him again. With a thought, these firebirds rushed towards the blood cloud.

"You think these few pathetic birds can stop me?"

After seeing Li Yunfan unleash the Fire Spirit Technique through the blood cloud, Wang Chan snorted coldly. Then, she plunged her hands into the blood cloud beside her and, without pausing, crashed directly into the dozen or so firebirds. The front of the blood cloud tumbled and swallowed the firebirds whole.

Upon witnessing this scene with his divine sense, Li Yunfan smirked, formed a hand seal, and silently chanted, "Explode!"

Under Li Yunfan's control, the firebird, formed from the Purple Nether Heart Flame, was swallowed by the blood cloud and instantly exploded, filling the blood cloud with a scorching purple flame.

"Sizzle"

As the burning sounds rang out, the blood clouds tainted by the Purple Nether Heart Flame were completely unable to resist being burned away.

Wang Chan, standing deep within the blood cloud, naturally sensed this situation as well. A look of surprise appeared on his face, and he hurriedly used the Blood Spirit Technique to control the blood cloud, trying to extinguish the purple flames. However, to his shock, he was unable to extinguish the flames!

Seeing the flames burning away the blood clouds, Wang Chan slowed down. In the blink of an eye, Li Yunfan's cloud-piercing boat disappeared into the horizon.

"Damn it! If I ever see you again, I'll tear you to pieces!"

Wang Chan glanced resentfully in the direction where Li Yunfan had disappeared, then immediately stopped and began trying to remove the purple flames clinging to the blood cloud. However, the flames were like maggots clinging to bones, and no matter what he did, he could not get rid of them.

Seeing how powerful the flames were, he dared not absorb the blood cloud into his body. If it got on his body, wouldn't he be burned to ashes?

"Damn it, what kind of flame is this? How can it be even more powerful than the Azure Sun Demonic Flame of the Demon Flame Sect!"

Wang Chan's face was rather grim. He had suffered a great loss today. Not only did he lose a protective treasure bestowed upon him by his ancestor, but he was also tainted by this strange purple flame, which could even burn the blood cloud formed by the Blood Spirit Technique.

Just then, an old man's voice suddenly came from behind him.

"Young Master, have any of the escapees been killed?"

Upon hearing this, Wang Chan immediately recalled Li Yunfan's face, and a surge of murderous anger welled up in her heart once again. She then hurriedly spoke to the old man.

"Elder Li, quickly help me extinguish the purple flames clinging to the blood cloud! These flames are incredibly strange; even the Blood Spirit Technique can't dispel them!"

A hint of surprise flashed in Elder Li's eyes, but he didn't ask any further questions. Instead, he flew directly into the blood cloud.

……

Hundreds of miles away from Yanling Fort, in a mountain forest, Li Yunfan and Dong Xuan'er were sitting cross-legged in a cave deep in one of the low peaks, surrounded by a transparent light curtain.

"Senior brother, can your formation really hide from the divine sense of a Core Formation cultivator?" Dong Xuan'er asked, looking at the formation with a hint of worry on her face.

"I don't know!" Li Yunfan answered readily.

Dong Xuan'er's expression froze for a moment, then she looked at Li Yunfan with a hint of resentment.

"I'm not lying to you, I really don't know, but now we have no choice but to try. After all, with our speed, it's impossible for us to escape the pursuit of a Core Formation cultivator." Li Yunfan explained with a wry smile after seeing Dong Xuan'er's eyes.

"How long are we going to stay here?" Upon hearing this, Dong Xuan'er finally put away her resentful gaze and sighed softly.

After thinking for a moment, Li Yunfan held up three fingers and said, "Three days!"

However, what Li Yunfan didn't know was that the other party hadn't actually chased after him at all. After helping Wang Chan get rid of the Purple Nether Heart Flame, Elder Li of the Ghost Spirit Sect persuaded Wang Chan, who wanted to continue chasing him, to turn back.

And so, Li Yunfan and Dong Xuan'er recuperated together in the cave for three days before quietly leaving Linzhou.

After that, there were no further incidents, and they flew all the way back to Huangfeng Valley in Jianzhou. After dropping Dong Xuan'er off in the valley, Li Yunfan immediately went to Green Wave Cave and informed them about the Yan family joining the Ghost Spirit Sect.

Upon learning this news, the other party's expression changed slightly. He then informed him of the demonic invasion and arranged for him to return to his cave to await a message from the valley. He himself left the cave to go to Huangfeng Valley to deliver the news.
