Heavenly Dao Engine

Qi Tian was determined to design the most advanced aircraft engine but accidentally lost his life while saving others. He then transmigrated to the National Master Manor in the Cultivation World and became a disciple of the National Master, with an extra engine appearing inside him.
Whether it's enemies or spirit stones and elixir, they all can serve as fuel for his engine. With the engine roaring, his cultivation journey is as unstoppable as a flying plane.
As a National Master, he assists in setting up emperors and selecting heirs. The nation thrives, and the people live in peace.
As a cultivator, he sweeps away all kinds of spirits and demons. Emperors bow their heads, and warlords make way.
What did you say? A monk wants to bring three great demon cultivators through here? Can you tell them that my engine needs an upgrade?
