Breaking through five realms in a single day, a god among men!

[Rating just released, will rise]
Having transmigrated to a martial arts world, Gu Lin was about to become a furnace for cultivation. He was already powerless and was about to turn into a dried-up corpse. Fortunately, the evil woman from the Hehuan Sect had already gone mad and died on the way.
Just when I was feeling lucky to have escaped with my life, I unexpectedly awakened my cheat ability: the Book of Merit!
"Indirectly eliminating the wicked woman of the Hehuan Sect, gaining 500 merit points, and receiving a max-level Xuanming Divine Palm as a reward!"
In an instant, he broke through from an ordinary person to the fifth level of the Meridian Opening Realm!
At this moment, Gu Lin was excited, but his eyes were also filled with great ambition!
......
The Book of Merit is a reward for slaying demons.
Exorcising demons brings rewards.
Execute corrupt officials, then reward them.
Eliminate treacherous officials and reward them.
Gu Lin became more and more enthusiastic in killing!
In the rigidly hierarchical and power-driven Yuhua Dynasty, in a cruel world where even the most outstanding people struggle to survive, in a dark age where demons and monsters run rampant, and against the backdrop of powerful clans monopolizing resources, Gu Lin still managed to climb to the top step by step with the help of the Book of Merit!
Until one day, the Demon Emperor and the Demon God descended upon the Divine Land of Feathered Ascension, turning the world into lambs to the slaughter. People wept in despair and rushed to their deaths one after another.
At that moment, someone lightly flicked their sleeve, their back view exuding arrogance!
[Fast-paced leveling up] [No suppression of the main character] [Extremely satisfying read]
