After the emperor pacified the four parties, he issued an edict to exile the various martial arts factions to isolated islands overseas. The once powerful master of martial arts is now trapped in a small place, struggling between survival and morality.
Amidst the chaos, some people stick to their true intentions, some take advantage of the situation, some piece together old fires from the ruins, and some break into the center of the storm carrying ancient inheritance. On the isolated island, grudges and beliefs collide fiercely, swords and thunder and fire intersect, the masters of the old era fall, and the power of the new generation breaks through the blood and fire.
When the imperial army pressed the border, the final battle of the rivers and lakes began. This is a group portrait story about inheritance and subversion, loyalty and betrayal. The lights of the old rivers and lakes are extinguished one by one, and the new road is stretching under the scorched earth - some people put away their swords and return to the world, some walk into the dusk and never look back, and some hold on to the remaining thunder light, waiting for the next rain.
