Signing in while in Qian Renxue's arms, becoming the main villain of Douluo Continent.

From the moment Lin Fan entered the Demon Thunder Abyss, he clearly sensed the demonic energy contained within the lightning, and could also detect extremely faint soul fluctuations within it.

At that moment, Lin Fan became wary. While cultivating outside, as the demonic energy entered his body, he also gained a general understanding of the strength of the Mad Demon Emperor.

If he were to encounter a true Demon Emperor, even if he had been sealed here for ten thousand years, Lin Fan would not dare to take the risk. However, this guy was only a Great Perfection Earthly Sovereign, and his power was weak at the moment. Therefore, Lin Fan first showed weakness and made the Mad Demon Emperor mistakenly believe that he had taken over his body. Then, when he was most relaxed, he struck a fatal blow!

As for the memories that the Mad Demon Emperor had read, they were naturally the scenes that Lin Fan wanted to present to him. There was no description of his own soul strength, nor were there any scenes of him being intimate with his harem.

"You brat, how dare you plot against me! Even if I die, I'll drag you down with me!"

Now that things have come to this, the Mad Demon Emperor's soul power has been completely suppressed by Lin Fan. It's too late to escape, and begging for mercy is unrealistic, because Lin Fan will not give him any chance to live!
As the cold and furious roar subsided, the Mad Demon Emperor's soul suddenly expanded rapidly, and the demonic energy emanating from his body reached an extremely dense and terrifying level. He actually wanted to self-destruct directly in Lin Fan's soul world!
"Just a death throes..."

Seeing this, Lin Fan's lips curled into a disdainful sneer. As his hand seals changed, a huge Primordial Ancestral Dragon and the phantom of the Yellow Spring Demon Saint appeared behind him!

"The Wrath of the Underworld!"

眸！
Three strange roars came out of Lin Fan's mouth in succession. The powerful sound waves mixed with the soul impact spread forward rapidly and struck the figure of the Mad Demon Emperor one after another!

The previously rapidly expanding and extremely unstable Rampage Demon Emperor froze in place as if he had been frozen in place. In that moment of distraction, Lin Fan seized the opportunity to release all the strange fires in his body, including the Undying Fire of the Nine Netherworlds and Amaterasu, forming a huge fire cage that enveloped the Rampage Demon Emperor's entire body!

"Ahhh!"

Flames have an extremely strong suppressive effect on souls, and the surrounding demonic energy does not provide much protection. With a thought, Lin Fan formed a fiery cone and pierced into the body of the Mad Demon Emperor!

The latter was like a punctured balloon, its inflated body rapidly shrinking. Taking advantage of this opportunity, the strange fire swarmed up, burning and spreading fiercely at its wound. Accompanied by the extremely miserable screams of the Mad Demon Emperor, he completely disappeared from this world!
Besides the pure soul energy, what was left behind was also some of the original demonic energy from the Mad Demon Emperor's body!

Lin Fan perfectly absorbed the soul power. After a slight hesitation, he swallowed the dark demonic energy that was releasing a strange aura, and then sat down cross-legged to enter a state of cultivation.

Half a day later, Lin Fan slowly opened his eyes, his face full of joy and excitement.

"Heh, this guy may be stupid, but he's done me a huge favor."

Lin Fan opened his palm, and a wisp of black demonic energy, like a small snake, swam out from his body, dancing freely at his fingertips under his control!
Lin Fan had always been troubled by how to generate and control demonic energy, but the appearance of the Mad Demon Emperor solved all of this!

During the time he took control of his body, Lin Fan was constantly experiencing and sensing the demonic energy firsthand. The Heavenly Thunder Seed was also taken into the body and refined by the Mad Demon Emperor. Lin Fan reaped the benefits without spending any money and made a fortune!

"After half a year... I never thought I'd have the chance to see the light of day again..."

Just as Lin Fan was secretly delighted, an old, weak but gratified voice slowly came from the altar.

A faint white light flickered, and the figure of an old man dressed in a silver-white robe slowly appeared. He looked to be in his sixties or seventies, with white hair and beard. Although there were some wrinkles on his face, he stood upright. In particular, his eyes were incredibly sharp, as if they contained thousands of lightning bolts, which were awe-inspiring...

"You are... Senior Tian Leizi!?" Lin Fan was slightly taken aback, but then he knew the answer in his heart.

"That's right... Back then, when my Heavenly Thunder Sect was invaded by the evil race from beyond the realm, even with the full strength of the sect, we were unable to kill the Raging Demon Emperor. In desperation... I sacrificed my body and soul to seal him here..."

"I never expected that guy would actually use demonic energy to infiltrate the seal... If you hadn't appeared and killed him... the consequences would have been unimaginable..."

Tian Leizi sighed deeply, his eyes still showing lingering fear.

"Extermining the extraterrestrial evil race is something that every person in the Great Thousand World should do. Senior, there is no need for thanks. This is simply my duty."

Lin Fan's answer was righteous and dignified, neither humble nor arrogant.

"Excellent, truly a promising young talent..."

Tian Leizi nodded in satisfaction, then his gaze slowly swept around, taking in the ruins, his eyes gradually becoming deep and filled with helplessness...

"The Thunder God Sect was once so prosperous... but now it has fallen into such a dilapidated state..."

"Now that you have absorbed and refined the Heavenly Thunder Seed, you lack the means to control and utilize it. I am now merely a remnant soul, and all I can give you is this Heavenly Thunder Heart Sutra..."

Tian Leizi's gaze returned to Lin Fan. As he finished speaking, he slowly pointed his finger, and a silver-white lightning bolt rapidly extended through the space, heading straight for Lin Fan's brow.

Lin Fan offered no resistance, allowing the lightning bolt to enter his mind, and a stream of information surged forth.

"Thank you for your kind gift, senior!"

A few minutes later, he suddenly opened his eyes, his face beaming with joy!

With the Heavenly Thunder Heart Technique, the Heavenly Thunder Seed within his body can continuously generate thunder power to forge himself, and can even release concentrated power for others to cultivate and use!

Once he fully masters the Heavenly Thunder Heart Technique, he will be able to unconsciously absorb the thunder energy from the outside world into his body. Lin Fan is now like a mobile thunder spring, capable of endlessly generating thunder power!

Furthermore, the demonic energy amplified the heavenly lightning, making him even more formidable!
"In you... I see the hope for the future of the Great Thousand World... The extraterrestrial evil race is strong, but the descendants of my Great Thousand World are no less powerful... I entrust this world to you..."

Seeing that Lin Fan had grasped the basics of the Heavenly Thunder Heart Technique in such a short time, a look of satisfaction appeared in Tian Lei Zi's eyes. His voice grew increasingly faint, and his blurry figure gradually dissipated...

"Farewell, senior! The vast world will never be allowed to be touched by evil races from beyond the realm!"

Lin Fan solemnly clasped his hands in the direction where Tian Leizi had disappeared, his eyes filled with determination and admiration!
Those who could unhesitatingly sacrifice their lives when facing powerful extraterrestrial evil races are the reason for the rich and colorful world we know today. Lin Fan will not allow anyone to take it away or destroy it! (End of Chapter)
