Sequel of Allison, taking place about 17 years after the original series.

Wang Zhong arrived in an alternate world and became embroiled in this world's global war.What he gained was a cheat, akin to a real-time strategy game's overhead perspective, and he could even see through the eyes of his subordinates' units!So, he decisively started micro-managing, “Shift the machine gun position five centimeters to the left! Place the anti-tank cannon in the forest on the right!”Three years passed in this manner, and Wang Zhong looked at the marshal's baton in his hand, then at the double-headed eagle flag behind the emperor's envoy.“In my hometown, there's an old saying, 'Princes and generals, are they not sprung from the masses?' Envoy, do you know of it?”

My parents are dead, my little brothers and sister are still young, with no one lending a helping hand, there are too many people looking to bully us showing up at my door! There’s still the most shameless pair of uncle and aunt eyeing our few acres of land, and even scheming to sell me off as a concubine! Treating my siblings as servants at their beck and call! If I was not forceful, how would we be able to live in peace? Don’t tell me that I should act like the previous Lian Fangzhou and die from extreme anger? In order to quell this bunch of demons, break out a wide path to walk on, angelic faces are useless, only the tricks used by malevolent spirits are the way to go!

- Description from Novelupdates

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.
