I found a huge plot hole, so I revised the story. The release date might end up being the same day (bows).
Same age / both each other's first love, no prior relationships
One second they were arguing, and the next they had transmigrated into an infinite-flow world with their nemesis?!
Zhong Zhenzhai and Xu Xi had been competing since childhood. Even a jar of peanut butter had to be settled with a winner.
But this time, the instant they both grabbed the jar, the world spun around them, and they were dragged into the infinite-flow world together.
Bizarre rules, deadly instances, and a single careless mistake could mean total annihilation.
Zhong Zhenzhai protected her, took the hits for her, and ground out through clenched teeth, "Xu Xi, stay close to me. Don't die."
Xu Xi obediently nodded, acting like a rookie who'd just arrived.
But she didn't tell him that this was already her second time entering this world.
Two years ago, she had faced countless instances filled with mountains of corpses and seas of blood all alone. She nearly lost her life there before finally discovering the mastermind's identity.
Because that person had set their sights on Zhong Zhenzhai's life.
So she came back, carrying a body covered in scars and a heart prepared to die. She returned to the starting point to face it all over again.
Before fate could strike him, she would cut that invisible hand off at the root.
To this day, Zhong Zhenzhai still didn't know that the girl beside him, the one who'd given him a headache for twenty years, had already died for him once.
