Gao Wu: F Level Equals a Mutated SSS?

[Ultimate killing + invincible excitement + all races in the abyss + extreme crushing] The abyss has descended, and the era of martial arts has begun! In the awakening ceremony that attracted the attention of the whole school, Lu Yuan awakened the talent recognized as the most useless—F-level [Basic Lancer]. The school belle broke off her engagement in public and became the laughing stock of the whole school. She was even thrown into the college entrance examination combat area with the highest mortality rate and was used as cannon fodder. However, no one knows that he is bound to the [God-Level Killing Mutation System]! Any junk rewards dropped by killing enemies will be forced by the system to be critically mutated, up to SSS level! "Ding! Kill the first-level ferocious beast, drop [Weak Qi and Blood], and mutate into [SSS Level·Chaos God and Demon Overlord Body]!" "Ding! Kill the tenth-level Beast King, drop [Basic Spear Style], and mutate into [SSS Level·World-Destroying Spear Style]!" In the martial arts college entrance examination, when the once-high-ranking geniuses were forced into desperation by the beast tide, they cried bitterly. Lu Yuan came over with a rusty iron gun in his hand and drew an ace. Boom--! The world-destroying black flames that filled the sky tore through the sky, instantly evaporating the tide of hundreds of thousands of beasts and the mountains! The governors of the province were horrified and threw up their tables. Principals across the country collectively went crazy: "Are you crazy! You call this world-destroying skill an F-level equal to an A?!" A few years later, the starry sky gods came and tried to obliterate Blue Star. Lu Yuan stood on the Great Wall of Starry Sky and shot through the boundless galaxy. "F-level basic spearman Lu Yuan, please die to all races in the universe!"
