This Thunder Sea originated from an Immortal Thunder that Xu Wangu had struck down. Immortal Thunder not only strikes the Physical Body but also attacks the Sea of Consciousness. As a result, not only was a wisp of Immortal Thunder that had entered the Human Smoke swallowed by the Three-eyed Bird Head in a single gulp, the Immortal Thunder attacking the Physical Body was also implicated, carrying away a part of it, likewise falling into the mouth of the Three-eyed Bird Head.
After swallowing the Immortal Thunder, the Bird Head fermented it for some time before spitting it back out, as if deeming it distasteful. However, the Immortal Thunder that had been swallowed by it transformed into the Thunder Fluid before us, constituting this small Thunder Sea, condensing without dispersing, no longer spilling out Thunder Light.
