Review Detail of DeadSaltedFish in Fantasy Simulator

The MC from an ordinary world travelled back in time, but he arrived in a parallel reality where martial arts exist and have a heavy influence in society. It is similar to World’s Best Martial Artist, but I would prefer not to compare it to that trash. His cheat allows him to simulate a world and assume the identity of a random person there. 10 years in there was equivalent to a moment in the real world, so you would expect a mature MC. At this point, It is similar to 48 hours a day. Also, his experience in the simulation was not just some filler, the plot is actually well thought out. It is a decent read.
