Shadow Lord: I Level up Alone

Ten years ago, the "door" connecting the world to other dimensions was opened, and various monsters continued to appear. As a result, demon hunters with different abilities also appeared, known as "Hunters." Lin Feng is an E-level hunter with the weakest strength. During a challenge mission, he encountered a terrible hidden challenge. The huge stone statue inside attacked everyone, pushing them to the edge of life and death. Lin Feng relied on his extraordinary vigilance and understanding to save his teammates several times, but they still suffered heavy injuries. In the end, he was kind-hearted and gave up the opportunity to escape to his friends, leaving him alone to face the enemy. At the moment of life and death, he actually got an upgrade system! With the use of the system, can he become the strongest hunter? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
