Death Simulation: I Inherit All Discoveries

After transmigrating to the cultivation world for eighteen years, Lu Xuan is nothing but a dying slave in the Blackstone Mine. He has no spiritual root, no background, and sees no future. Until the day the mine collapses, he gains a strange ability in the underground ruins—Death Simulation. Each time he dies, he enters a simulated life. And after each simulation ends, he retains the rules and secrets he discovered. [The Crimson Flame Wolf reveals a fatal flaw every thirty breaths.] [The spiritual herbs in Withered Wood Valley regrow at midnight.] [The true entrance to an ancient secret realm has never been opened.] ... Gradually, Lu Xuan realizes that what he inherits is never cultivation, but a deeper understanding of this world. Others cultivate techniques; he studies rules. Others compete for opportunities; he seeks loopholes. Others fear; he is greedy. Until one day, he discovers something that could overturn the entire cultivation world—the greatest secret of this world may lie within the Heavenly Dao itself. — Description from novelcodex.org
