Narumi was originally the most talented and the most promising candidate to become the next Poseidon. Unfortunately, he lost all his souls and fell into the sky and forgot his past.
Lu Yuan, the god of heaven, once took advantage of the love of the heir of Poseidon in order to fight against the barbaric and dark forces. When the truth was exposed, Poseidon swore to stand side by side with the god of heaven by giving up his position as a god. The god Lu Yuan rejected Narumi in front of the gods, and Narumi destroyed himself and fell to heaven. Lu Yuan didn't know that his lover was so determined, so he had to release his artifact Jade Linglong when Narumi fell to the sky and follow Narumi to destroy him, just to find this person again.
