The Black Demon Lord spoke slowly and deliberately, clearly having piqued everyone's interest.

Lin Xiao didn't speak. He silently glanced at the future relationship between himself and the Black Demon Lord. Only after seeing that he had indeed obtained the true inheritance from the Black Demon Lord did he breathe a sigh of relief.

He then replied, "Okay! I promise you."

Then, Lin Xiao walked over and, under the guidance of the Black Demon Lord, went over.

He then took a scroll from the Black Demon Lord's body.

[Spirit Seed Seizure Technique: A Saint-grade cultivation technique that implants a demonic seed into another person. Once the seed matures, it can be retrieved and refined. The person whose seed is retrieved will die instantly. (Note: This technique only applies to those below the Saint realm!)]

Looking at this sinister technique, Lin Xiao couldn't help but gasp.

"What a powerful technique! But won't there be any side effects from forcibly refining the demonic seed?"

Lin Xiao asked with concern.

The Black and White Demon Lords said with absolute certainty, "Of course not!"

"Back then, we planted demonic seeds in half of the cultivators in a Dao Domain. Once the demonic seeds matured, we refined them, which allowed us to break through to the Supreme Realm!"

"Without this method, do you think we could have cultivated to the Supreme Realm in just tens of thousands of years?"

"If it weren't for those hypocritical old bastards scheming against my sister and me, we would have refined three demonic seeds from three Dao Domains and reached the Quasi-Emperor Realm!"

"Oh! By the way, you have to be careful when you use this technique outside, there are quite a few people out there who know we exist!"

Hearing the Black and White Demon Lords' reminder, Lin Xiao smiled faintly and said, "Don't worry, seniors, I will be careful."

"In that case, you can start cultivating the demon seed here. My sister and I will guide you here to cultivate the demon seed. It will only take two days."

Lin Xiao murmured upon hearing this, "Two days? That's good enough to finish cultivating the Demon Seed. It's time to deal with Su Chen."
