Dacheng is a male minor character and one of Ma Yan's subordinates who led a rebellion against him. He attacked Ma Yan from behind with a baseball bat, striking him twice in the head. He was one of the four men who subdued the enhanced Ma Yan. During the search of Ma Yan's belongings, he found the leather strap bracelet and loosened the ropes binding Ma Yan's wrist, which allowed Ma Yan to execute his counterattack. Ma Yan retaliated by stabbing Dacheng in the left eye with a hidden dagger, gouging out his eyeball. Despite his severe injury, Dacheng managed to grab Ma Yan's machete and later pulled a large axe from Ma Yan's spatial inventory. He clashed with Ma Yan again but was clearly losing due to his injury. He was eventually defeated and killed by Ma Yan, who slashed his shoulder before Dacheng collapsed.
