On her eighteenth birthday, the day everyone changes professions, Su Nian awakened the universally scorned D-rank talent "Contractor" and summoned a small black coffin, becoming the laughingstock of the whole school.
The coffin lid cracked open. A pale, slender hand gripped her shoulder: Ye Wujiu, the Lord of the Nine Netherworlds, an SSS-rank forbidden being who had slumbered for ten thousand years. Her blood had accidentally awakened him, and he forcibly bound her to a soul contract.
While others desperately sought a single piece of purple gear, she casually pulled divine artifacts from the Lord's private vault. While others formed parties to grind dungeons, she led the Lord around like a walking natural disaster.
But beneath Ye Wujiu's gentle facade lurked a desire for revenge: he planned to use her to reopen the gates of the Nine Netherworlds and destroy the Divine Realm.
Meanwhile, the "Vessel of the Gods" sealed within Su Nian was gradually awakening. The Divine Court issued an order to hunt her down, calling her "a walking natural disaster."
When the Lord of the Nine Netherworlds prepared to sacrifice her to bring the Nine Netherworlds into the world, Su Nian grabbed the contract chain and pulled him back to the human realm.
"I'll avenge you, and I'll sit on your throne with you."
From then on, the two joined forces to bring down the Divine Realm.
It's very innovative and the writing is very good. Why isn't it rated?
