An F-Rank True Spirit Is Weak? One Sword and I Rule All Ages!

[Contracted by the Campus Belle]+ [Overpowered Protagonist]+ [One Sword to Slay All Races] After transmigrating to a world where people contract with spirit beings, Ye Feng became an F-rank spirit being inside a spirit altar. When Liu Ningshuang's ten-pull produced two golden lights, one revealed an S-rank spirit being, a Six-Winged Angel, while the other revealed an F-rank spirit being: Ye Feng! Her S-rank spirit being had turned into a useless F-rank one, and Liu Ningshuang was furious. But she had no idea that Ye Feng, a transmigrator, possessed the [Strongest Spirit Evolution System]. As the most worthless F-rank spirit being, no one was willing to contract with Ye Feng. He was on the verge of disappearing because no one would contract with him. Bai Wanqiu, the campus belle who had failed to summon a spirit being, chose to contract with Ye Feng and even selected a [Life-and-Death Contract]! And so, the strongest spirit being was born. He gained a spirit evolution path: the sole ruler of all eternity, the Desolate Heaven Emperor. [Ten Fiend Treasure Arts]+ [Magic Immunity]+ [Calming Chaos Art]... With countless arts at his disposal, Ye Feng became virtually invincible! Years later, Ye Feng held the Emperor-Slaying Sword and stood atop a pool of laws, like a Heavenly Emperor descended into the world. Alone, he swept through the myriad races of the alien dimensions! Watching Ye Feng's incredible performance, Liu Ningshuang was consumed by regret. “That’s my spirit being! Give him back to me!” Bai Wanqiu merely smiled and leaned shyly against Ye Feng. “Sorry, Ye Feng is my spirit being!”
