Mortals Make Gods

Without spiritual roots, one is useless in this world of cultivating immortals. Lu Zheng didn't care. He was an engineer in his previous life. The monk has spiritual fire? He has a blast furnace. The monk has a flying sword? He has artillery. Do monks have a way to heaven? He has a saying: "You call this the 'circulation of heaven and earth's energy'? I call this fluid mechanics." He is not here to cultivate immortality. He's here to change the rules.
