Cultivation? I've Used the Electromagnetic Gun

I, the Doctor of Double Materials, transform into a useless person with all my spiritual roots destroyed. When everyone forced me to kneel down, I took out the theory that "the essence of aura is quantum tide". They use magic weapons, I use electromagnetic guns; they draw talismans, and I write programming talisman arrays; they practice hard to ascend, and I build a "planetary engine" to take the entire continent to ascend!
