Vessel of Worlds

He died a scholar. Reborn with the infamous Five Roots, he carried the worst cultivation aptitude his sect had ever seen — and became the laughingstock of everyone in it. At fifteen, they threw him out with nothing but an old iron bowl looted off a dead bandit. Except the bowl held a secret. Leave anything inside it — a cracked pill, a worthless stone, common junk — and it comes back better. Rarer. Stronger. No one can ever know he has it. He doesn't need talent. He just needs time, patience, and one secret nobody can take from him. One bowl. One nobody. A world that's about to find out what he can become. Vessel of Worlds — a xianxia progression fantasy about an outcast, a mysterious bowl, and the long road from nothing to everything. — Description from novelcodex.org
