The fiancé her mother had originally set up for her, whose identity was usurped by her sister, comes to her rescue. She says, 'You saved me, I have nothing to give you as repayment but myself.' Yet when her mother comes, she coolly claps her hands and walks away with her.Captain Gu traps Meng Yu against the wall: 'Flirt with me and then want to run? No way!'Meng Yu resists: 'That was just a temporary measure for revenge.'Captain Gu leans in: 'We've planned everything, let's go with it. I'll help you take your revenge, and you just need to repay the favor.'A slightly silly Meng Yu asks: 'What favor is that?'Captain Gu smirks: 'The life-saving favor that should be repaid with oneself.'Meng Yu: 'Is this fox really the officer I knew in my past life?'

Su Wan, a beautiful lord, had no doubt that she could easily become the most powerful lord in the universe.

She felt her heart beating fast when she first saw her starter hero dazzle amidst the flashing summoning light.

Unbeknownst to her, her nightmare was about to unfold.

While other heroes devoted themselves to training day and night in order to level up, her hero goofed around and showed no effort to improve himself.

While other heroes charged into the enemy’s base and valiantly killed off their foes, her hero hid in their base and slept soundly.

As time passed, Su Wan slowly discovered that there was more to her hero than met the eye.
