I Grind Proficiency to Cultivate Immortality by Taming Ghosts

Zhou Li is ruthless, avaricious, and decisive in killing. After transmigrating to a dangerous world where ghosts have returned and vengeful spirits run rampant, he discovers a special supernatural profession: ghost cultivators.

In his previous life, Zhou Li was just an underground bare-knuckle boxer and had no real advantages. Fortunately, transmigrating came with a golden finger: a proficiency panel.

All he has to do is train his skills to increase his proficiency and level them up.

Other people need talent to cultivate and are held back by bottlenecks. Zhou Li only needs to max out his proficiency to grow without limits.
