The principle behind flight techniques was to consume spiritual power and increase one's own kinetic energy output.
This was the principle behind the mainstream escape techniques of this universe. The escape techniques of the Earth Folk, Water Folk, and Wind Folk all stemmed from this. The Fire Folk had unusual constitutions; most of their kind possessed almost no rest mass, so their escape techniques were rather unconventional.

Anything else—"adding legs," "adding propellers," or "making it jet-powered"—did not fit the Aura Universe's mainstream of "integrated construction."
That would be twice the effort for half the result, far inferior to the current structure where a few talismans could settle everything.
However, this "extra kinetic energy" was not only easy for oneself to manipulate; it was also relatively easy for others to interfere with.
And the one who had left the deepest impression on Wang Qi was naturally the True Flame God.
Back beneath Gu Yan, Wang Qi had used the flying-sword method to control a flying fist and hurl it out, only for the True Flame God to directly seize the kinetic energy attached to it. It could then only move slowly on inertia and could no longer accelerate.
But the current Wang Qi was only stronger than the True Flame God of that time.
"Since you're still not awake, then stop for me!" Wang Qi shouted.
Within the Savior Devil Realm, the Seven Emperors immediately sensed something.
The Emperor Fawen's face was filled with lingering fear. "What cultivation technique is this, to seize the vitality and power of
