Douluo: Elemental Secret Realm

A past life is but a memory, this life forges a legend. A young man from Earth is unexpectedly reborn into Douluo Continent. With a system, rewards, and opportunities in secret realms, he battles geniuses and creates a glorious life. The system intervenes, creating elemental secret realms. The continent is in chaos as the membranes of parallel worlds break. Characters from Douluo II (such as Huo Yuhao) and Douluo III (such as Tang San) appear. The story begins with the protagonist's sixth birthday, where he is given a choice between an SSR-level spirit awakening orb, a divine artifact, or a divine bone.
