After Ascending to Immortality, My Tsundere Nemesis Begs to Be My Sword-Bearing Attendant

On the first day I attained the Dao and became an Immortal of the Mortal World, I captured my arrogant nemesis, whom I'd fought for five thousand years, and made him my sword attendant.

Every day, he fantasizes about turning the tables on me, not knowing that I can hear his thoughts and rewrite the Heavenly Dao System!

When a transmigrator arrives with a White Lotus System to win us over, I casually edit the underlying code.

The White Lotus System instantly becomes the [Haul One Hundred Thousand Tons of Bricks Every Day System], and the romance system turns into [Confess Your Love to Your Nemesis or Die]!

Watching my rival blush and curse while being forced to confess his love to me, I smile.
