Thirteen years ago, the Beiguan Wuzi Army was destroyed, and the flag leader Lin Chenchuan was recorded as dead in battle.
Thirteen years later, a black coffin revealed his true name, and also awakened the ancient city and demons buried under the mountains and rivers.
In order to keep his name and find his missing old friend, Lin Chenchuan relied on three unknown bone drawings to resume his spiritual practice. From then on, he carried the coffin and traveled around the world, slaying evil spirits, breaking through forbidden areas, and tracing the truth behind the destruction of the Wordless Army.
