I Refined My Spiritual Roots into a Reactor

When Yun Che traveled to the world of immortality, he thought he was getting Long Aotian's script, but he awakened the worst and most polluted "barren spiritual root". When everyone, including Tiandao, believed that he would be a loser, Yun Che smiled: "You haven't learned about nuclear fission in nine years of compulsory education, right?" So on the stage of the Immortal Competition, all the geniuses stared at the strangely rotating gray crystal in horror, and asked in a trembling voice: "What is this move of yours called?" Yun Che calmly pushed up his non-existent glasses: "This is a miniature deserted nuclear fusion reactor." However, before he could finish his words, the Heavenly Dao rained down a world-destroying thunderbolt on the sky above the sky.
