The Strange Arrival Begins and I Summon Black and White Impermanence Season 4

Strangeness descends on the world, and the order of yin and yang collapses. Ye Yu awakened the underworld system, took charge of the underworld and incarnated as the Yin Emperor, and successively summoned the Yin gods such as Black and White Wuchang, Zhong Kui, and Meng Po to return to their places. He purified the 100,000 trapped ghost soldiers in the Black Blood Ancient Tower, subdued the forces under the King of Zhenbei, sent the underworld army to the border, and joined hands with the ghost masters and Taoists and Buddhists to defend against the enemy.
