I Have a Life Simulator.

Wang Lei traveled to a world of advanced martial arts and awakened a simulation system, allowing him to simulate his future life, retaining any positive changes after the simulation.

[You diligently saved money and finally purchased a secret manual. After 10 years of practicing the "Iron Sand Palm" technique, you gained palm power comparable to those in the internal organs refining stage.]

[At the end of this simulation, you gained a positive change that enhanced your palm power, eliminating the negative change that had blocked your palm meridians due to practicing Iron Sand Palm.]

………

After countless simulations, Wang Lei gradually realized that no matter what Sword God, Martial God, or Knife God…… they could all be resolved with a single move.
