Strangeness is coming: I can summon the underworld soldiers

The day the strangeness began, Lin Jiuyin’s mother vanished from their home without a trace. Black fog swallowed the city, and the living either turned into monsters or corpses. In that chaos, he awakened a system—the Yin Soldier Summoning System. Its price was whitening. Each summon turned part of his body white, starting from the fingertips, losing warmth and sensation. If it reached his heart, he would die. Lin Jiuyin didn’t care. Bai Wuchang thanked him, Black Wuchang had no choice, and the soldiers of the underworld obeyed his commands. Weirdness followed rules, but Yin soldiers were not bound by them. While others fled for their lives, he searched for his mother. While others waited to die, he summoned stronger Yin soldiers. Before the whitening spread to his heart, he intended to bring the underworld into the human world.
