Jiang Cangming, the leader of the Dragon King Palace, was plotted by his old enemy Dark Shark and imprisoned in a 10,000-meter-deep sea dungeon. He was seriously injured and his dragon veins were damaged, and he became a prisoner at the mercy of others. In a desperate situation, he was accidentally bound to the ancient Poseidon system and was forced to feed on sea water, starting the road of devouring in humiliation.
From struggling to swallow 100,000 tons of seawater every day, to unlocking powerful skills such as Whale Swallowing and Tsunami Throat, Jiang Cangming used the power of the system to achieve nirvana and be reborn. Not only did he break free from the shackles of the dungeon, he also used thunderous power to avenge the Dark Shark, draining the enemy's coastline and crushing its elite fleet.
However, there is a fatal secret hidden behind the system - it is not a boost, but the remnants of the ancient Poseidon, which once devoured eighty-one hosts in an attempt to be reborn through Jiang Cangming's dragon veins. Faced with the system's backlash and the temptation of Poseidon's will, Jiang Cangming relied on the Dragon Blood Returning Technique inherited from the Dragon King Palace to refine Poseidon's will and take control of the situation.
Revenge is over and Dragon Domain is rebuilt. It seems that the dust has settled, but the strange whispers at the bottom of the deep ocean trench and the awakening of older existences indicate that a greater crisis is quietly brewing. He uses dragon blood as his blade and sea water as his weapon, vowing to protect the dragon domain and uncover all ancient secrets.
