“For a long time, we humans have been like the chosen race, without any natural enemies, and have long been at the top of the food chain. Unfortunately, I have to tell you...” “When there is only one bird in a forest, then the forest is basically fake, and the bird was put there by someone...” “No matter how a fish swims, it can never meet any of its kind, which only means that the fish is kept in a fish tank...” “Yes, we are the birds in the forest and the fish in the tank.” “Yes, the world we live in is virtual!”

This novel is also known as Only I Level Up

10 years ago, after “the Gate” that connected the real world with the monster world opened, some of the ordinary, everyday people received the power to hunt monsters within the Gate. They are known as “Hunters”.

However, not all Hunters are powerful. My name is Sung Jin-Woo, an E-rank Hunter. I’m someone who has to risk his life in the lowliest of catacombs, the “World’s Weakest”.

Having no skills whatsoever to display, I barely earned the required money by fighting in low-leveled catacombs… at least until I found a hidden catacomb with the hardest difficulty within the D-rank catacombs!

In the end, as I was accepting death, I suddenly received a strange power, a quest log that only I could see, a secret to leveling up that only I know about! If I trained in accordance with my quests and hunted monsters, my level would rise.

Changing from the weakest Hunter to the strongest S-rank Hunter!

- Description from Novelupdates

Ye Chen transmigrated to a fantasy world by chance. He was well-aware of how dangerous this world was, so he kept a low profile and quietly cultivated in Xuantian Holy Land. He tried his best not to get involved in any affairs for fear of getting caught up in any vendetta.

If he encountered problems that he could not run away from, he would ensure that he annihilated all his opponents as swiftly as possible.

He showed no regrets for staying aloof and no remorse for killing his enemies.

Hundreds and thousands of years later, Ye Chen’s disciples were domineering existences in the world, and their influences spread far and wide. On the other hand, Ye Chen was steadfast to his principle of not drawing any attention to himself.

…

One day, the Heavenly Path experienced significant changes, and all the demons and gods throughout history attacked Ye Chen simultaneously. Ye Chen was forced to defend himself.

He drew out his sword and easily eradicated all the demons and gods, resulting in the collapse of the Heavenly Path.

Ye Chen blinked his eyes in disbelief and said, “Was that all?”
