Xue Rong was tasked with saving the protagonist of the world from villains clutches by his system. He has to travel from world to world and protect the protagonists, to prevent the destruction of the world.

In the first world...

Xue Rong: "System, let's save this world!"

System : (Yes! Let's stop the villain from getting stronger!)

Xue Rong sees the villain, and then...

"System, I like him!"

System : (What are you saying!! Don't be mad, our target is not the villain but the protagonist!)

Xue Rong: "I only love him; he is the apple of my eye!"

System : (My host turned blind in love in the first world, what to do? Waiting for the reply online!)
