Ren Baqian took out another small box from the bottom of the big box. Inside, there were two dark-colored belts as well as an electrical accumulator.
Each belt was an electromagnet.
For the sake of safety, Tu Hong wore a hoop made from a strong magnet while Ren Baqian wore two electromagnetic belts.
When energized, one belt would repel the magnetic hoop on Tu Hong because the two magnetic poles on both sides were the same. The other belt, when energized, would attract Tu Hong's magnetic hoop because the two magnetic poles were opposite.
For this match, the most frightening thing was that the difference in height between the two would cause mutual repelling and mutual attractive fields to change. For example, if Tu Hong jumped above Ren Baqian's head, Ren Baqian could adjust his posture and switch the position of the belts.
