I Refined the Sect into a Magic Weapon

The soul of a Mahayana monk who failed to overcome the tribulation passed through the useless outer disciple, bound to the "Industrial Revolution System", and transformed the world of immortality with steel, coal, and steam engines. While others were flying with swords, he was laying railroads, while others were making elixirs, he was making steel, and while others were setting up formations, he was building forts. A hundred years later, the sect became a spiritual industrial empire spanning hundreds of thousands of mountains. The demon king attacked the mountain and three thousand spiritual anti-aircraft cannons taught him how to be a new man. Then unlock the "Psychic Aerospace" branch, with the goal: to break out of this world and find the truth about the failure of the past life to overcome the tribulation.
