From the Start, I Raise a White Snake; Its Flooding of Longhu Mountain Shocks the Celestial Master

Meng Li unexpectedly transmigrates into the world of The Outcast and becomes an apprentice to Old Meng, a temporary worker. Bound to a Contract System, he can randomly make contracts with monsters and command them. And so Meng Li sets out on a journey to contract monsters. Contracting the Green and White Snakes unlocks the ability to flood Jinshan Temple and control fish. Contracting Taoyao unlocks medical skills that can heal humans, ghosts, spirits, and monsters alike. Contracting Tushan Yaya unlocks every ice-based technique, allowing him to turn anything into a glacier. And so on... Meng Li secretly contracts monsters and grows steadily stronger, right up until the Luotian Grand Ceremony. He restores Tian Jinzhong's limbs, floods Longhu Mountain, freezes everyone from Quanzhen with his Absolute Zero Domain, and poisons Wang Ai and Lu Ci, two of the Ten Elders, with his Myriad Poisons Body. Everyone is stunned. Xia He: Hahaha, is Meng Li sure he didn't come to Longhu Mountain to wreck the place? I like him! Zhang Chulan: Hey, bro! I invited you here to protect me, not to take me out! Old Celestial Master: Sigh... At least leave me my mountain!
