I Changed Class to Sword Immortal, and Even the Gods Fear My Billion-Sword Strike

After transmigrating into a world where everyone changes class, Su Yu was publicly confessed to by a scheming campus belle, and his System was activated on the spot.

What? To awaken as a Sword Immortal, he had to reject the campus belle and passionately kiss his deskmate in front of everyone?

What was there to hesitate about!

[Ding! Congratulations, Host! You have successfully changed class to the unique hidden class: Sword Immortal!]

[Ding! Congratulations, Host! You have obtained the Thousand Waters Sword, the Dragon Abyss Sword, the Taiyi Sword, the Chixiao Sword, the Heavenly Emperor Sword...]

[Ding! Congratulations, Host! You have obtained Sword Flight, Ten Thousand Swords Return to the Origin, Primordial Spirit's Return to Life, Heaven and Earth: One Sword Slash...]

Years later, Su Yu gazed at the gods filling the sky as billions of divine swords flew from the sword case on his back.

"If you can withstand my billion swords, you get to live!"
