- Description from Novelupdates

The ancient continent of Wu is a place where cultivation is law and the strong reign supreme. Thousands fall to their knees when the strong appear, and rivers of blood flow when they’re angered.

A peak expert known as Xie Di fell and was reborn in a young man beaten into idiocy. He lost all of his memories and his cultivation was crippled, causing him to be despised by all. To rid his shame and fight against the destiny of being toyed by others, the young man cultivated with all his strength, killing experts, and splattering the whole country with blood. All until the day he becomes a martial god who shatters the firmament and scorns mortals.

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.

The miracle doctor, Xu Qing, accidentally fell into the water and died. When she opened her eyes again, she found herself having transmigrated into a farming novel. Then, she felt excruciating pain in the lower half of her body. Xu Qing looked down in disbelief. As a thirty-year-old unmarried single woman, she was in the midst of giving birth to a child! Staring at the three babies who were barely breathing, Xu Qing almost went mad. Why did she suddenly become a mother of three?

Her father exclaimed, “How dare you give birth to b*stard children before getting married?! We don’t have a daughter like you. Scram!” Before Xu Qing could even catch her breath after bearing children, she was chased out of the house by her father. Fortunately, her mother pitied her and secretly gave her an acre of land to aid in her survival. With no options left, Xu Qing picked up a hoe and started farming.

‘Hey, that unconscious mister over there, please die somewhere else! Don’t dirty my corn field!’ After dragging the unconscious man to a side, Xu Qing suddenly remembered that she needed help taking care of her children. This man would do!

Later on, Qiao Yanhui knelt down before his angry wife with an aggrieved look on his charming face. He had one child on each arm, and another clinging to his head. He looked up at Xu Qing pitifully. “Honey, it’s the effect of my family genes. I can’t control my genes from producing so many babies…” “Out! Get out now!” Xu Qing kicked him aside. Who knew that the man she picked up turned out to be the father of her children. Had she known, she would’ve left him to die in the corn field.
