After My Family Was Wiped Out, I Awakened the Martial Arts Upgrade System

A former genius? I, Lin Feng, am making great progress with the addition of the system! Besieged by enemies? Lin Feng sneered: "System, upgrade it for me!" The elder of the sect said: "This evil boy breaks through the realm in one day, how terrifying it is!" Mainland Powerhouse: "What? With one man and one sword, he penetrated the forbidden area?" Peerless beauty: "Mr. Lin, please accept my token of love!" Is God unfair? Lin Feng held a long sword and walked against the sky. All the bullshit geniuses, sects, and strong men were all reduced to dust under the upgrade of the system! Demon Emperor: "No, this world is going to be penetrated by him!"
