Lin Ran was transmigrated to a fantasy world and was the top scorer during the martial arts exam.

He was assigned to protect the empress, but because he did not give presents to the general director in charge of the palace affairs, he was demoted to a guard at Mount Sword.

His only job was to clean the swords stored on the mountain.

[You have cleaned the broken sword, Fire Stream. You have been rewarded with 50% proficiency of the Heaven Fire Sword Will.]

[You have cleaned the heavy sword, Dragon Elephant. You have been rewarded with the inner energy of the Dragon and Elephant Divine Art.]

[You have cleaned the demon sword, Dark Wind. You have been rewarded with the Grade 9 method, Phantom Step.]

[You have cleaned the spirit sword, Heaven’s Chance. You have been rewarded with the Eyes that Peek into Heaven.]

“Isn’t this way better than working as the empress’s guard?” Lin Ran quickly decided to remain on the mountain until he had become invincible.

He spent the next 100 years without leaving Mount Sword until the day the barbaric knights from the north invaded the central plains and started to mercilessly slaughter citizens, hoping to break the peace that was obtained through a lot of sacrifices over 100 years ago.

Lin Ran had no choice but to descend from the mountain.
