Bullet Time
Bullet Time was a physiological phenomenon that was not very well-known.
When the human spirit exceeded a certain limit, their thinking speed, observation ability, and reaction speed would increase greatly. The world around would feel as though it had been slowed down by a slow button; in this state, they could even dodge bullets shot at them.
This was a special state called Bullet Time.
The hormone responsible for causing this increase in nerve activity was adrenaline.
As Feng Lin drank what was likely a perfect-grade Adrenaline Potion, he felt the world slow down to the max. His soul seemed to be in another space that was overlooking the world from God's perspective.
People's movements seemed to come to a halt. The change was slow but orderly.
This was a wonderful feeling. His soul seemed to have exceeded its bounds. He could sense everything in the world, gaining a sense of omniscience.
