He traveled through time and became the puppet emperor Ji Xuanche who was ignored by the sect, and awakened the [Gate of Truth] system. He discovered that the body-protecting Gang Qi of the immortal cultivators was afraid of acid corrosion, that flying with the sword violated aerodynamics, and that the formations were nothing more than complex integrated circuits.
Faced with the sect's pressure to hand over the throne, Ji Xuanche sneered: "I am the emperor, hunting on behalf of the sky, how dare you traitors usurp the throne?"
He no longer prayed to immortals, but instead supported the Mohist remnants and started the "Great Xia Industrial Revolution."
The first step is to break the gang with gunpowder. He used his knowledge of chemistry to improve black gunpowder, developed a "magic-breaking bullet" that was designed to break the protective aura, and destroyed the Qingyun Sect's mountain gate in one battle.
The second step is the steam mecha. Using the laws of thermodynamics to build the "God Machine Camp", the steel puppet holds a Gatling to fight against the Yuanying old monster.
The third step is to cultivate immortality through electricity. Establish the "Daxia Power Grid" to convert spiritual energy into electrical energy, allowing mortals all over the world to use "spiritual electrical appliances" and break the monopoly of cultivating immortals.
When the sect reacted, Daxia had laid railways and airships covered the sky. Ji Xuanche stood in front of the nuclear fusion reactor and announced to the trembling world of cultivators: "In this world, science is the only god."
