Dinghai: The Ocean Pillar is structured as a roguelike. The Abyssal Dragon sets out on repeated runs, and each attempt brings new choices of weapons, abilities, and paths. Progression is built around persistence through failure.

As the developers describe it, every run brings new choices, and every death is a step toward something stronger, so setbacks feed directly into future attempts. Each cycle is also framed as revealing new pieces of a buried truth.
Building a Run
Weapons are chosen at the start of each run, and abilities are unlocked and combined along the way, so no two attempts play out the same. See Combat for how the dual-weapon system shapes each run.

Justdan describes the structure as randomized stages combined with progression that accumulates between attempts, so a run that ends in defeat still leaves the next one stronger. Alongside the per-run weapon and ability choices, that persistent layer is what carries forward.
Boss Encounters
Runs are punctuated by imposing boss encounters that test the weapon and ability combination a player has assembled. Three named bosses have been shown: Xiangliu, the armoured turtle Xuangui, and a paired fight against two Jiaochong. Where each falls within a run has not been detailed.
What Runs Uncover
Repeated attempts are framed as the way a single large mystery is gradually opened up rather than delivered in one pass. Three threads are named as running through it: what became of Yu, the wish Yi never fulfilled, and the regret the fallen general spent his life pursuing. Each cycle is described as returning another fragment of the truth. See Gods and Mortals for the figures involved.
