Cultivation of Immortality: Burning Heaven and Ember Body? I Choose to Refine Weapons!

[Cultivation of Immortality + Weapon Refining + Sub-Professional + Tianjiao + Shuangwen + Development of Technology] As a good young man in the 21st century, what is it like to travel to the world of immortality? My name is He Qingyan. I am a college student in the Department of Physics. I accidentally traveled to the world of immortality and awakened the Heavenly Fire Spiritual Root. But can Huo Linggen only play with fire? Looking at other fire spirit root cultivators, well... It seems they can only play with fire... But I am different! I seem to have a special physique - Burning Sky Ember Body Heaven level fire spirit root? It's just incidental. I can practice weapons, make magic weapons, and develop technology I can play on the ice and absorb the heat, absolute zero I can explode troops, whether it's the Human Emperor's flag, mechas, or using Netherfire to resurrect skeletons and frame a steady stream of labor.
