Cultivating Immortality in Douluo: Fusing with the Desolate Ancient Sacred Body from the Start

[Two crossover fanfictions]

P.S. This combines the Shrouding the Heavens trilogy with Douluo, though the Douluo portion is very short. Most of the story takes place in Shrouding the Heavens and Perfect World. I haven't settled on a proper synopsis or title yet.

In Douluo Dalu, Martial Souls and soul power are undoubtedly the foundation of everything.

If you awaken a Martial Soul but have no soul power, you'll be an ordinary person for the rest of your life.

Li Xuan was one such person. His soul transmigrated into Douluo Dalu, where he awakened a Martial Soul but had no soul power.

However, he bound a cultivation System and merged with the Desolate Ancient Sacred Body right from the start. By completing missions, he gained a System that would make him invincible, beginning in Douluo.
