The essence of sword Qi was nothing more than a special kind of energy.
As long as the energy was strong enough and condensed enough, it could be transformed into a physical energy body. Such an operation was not rare in the world of cultivation. The only difference was the stability of the energy body.
However, if it was the other way around, turning physical bodies into pure energy was an eye-opener for Lin Yi.
Even Lin Yi couldn't help but shiver when he felt the terrifying human-shaped energy fluctuation in the distance.
He subconsciously thought of the mass-energy equation in the secular world.
The originally insignificant physical matter, once transformed into energy, would cause an earth-shattering ultimate explosion. This was the origin of nuclear weapons in the secular world.
However, in front of them, ye Qiyuan's entire body had turned into sword Qi. If the mass-energy equation was still valid, how terrifying would the power be?
It was unimaginable.
