Simulation of Destruction: Why Am I Always the One Who Becomes the Arbiter?

Ye Chang'an has bound a simulator system that allows him to change the destinies of others, increasing the number of simulations. However, each simulation results in him becoming the Arbiter.

"In the first life, I was in the Pre-Civilization. I grew up with Eden, and we entered into marriage. As the Destruction frequency increased, I thought I could survive with Eden for fifty thousand years... but I ended up becoming the First Arbiter."

"In the second life, I was in the Current Civilization. I was childhood friends with Sirin, and we were both captured for experiments. As the Destruction energy surged, I thought Sirin would become the Arbiter... but it was me who became the Arbiter first."

"In the third life, I was in the Pre-Civilization again. I grew up with the Sakura sisters in the Far East, and I became a partner with Sakura as assassins. As... alright, alright, the Third Arbiter is also going to make me change, huh?"

Every time a simulation occurs, as long as there is an Arbiter disaster, there is at least one Ye Chang'an among the Arbiters.

"System, you better give me an explanation."

"...You have set your Destruction energy resistance too high."
