201 Last Night (All to the Arena).

Elder Joules nodded at elder Fatso, and the both of them made hand seals as the energy in the formation was slowly released.

This was energy that had been accumulated from the fight above.

It was energy from all the participants of the tournament.

From the first day, energy had been stored in the formation, and now, it was going to be used.

The process was simple. The Yin and Yang talent swapping flower was very sensitive to energy.

Depending on the amount of energy, it's petals would change color.

Because of this, it needed to be grown in very special environment where it would only absorb specific energy for very particular areas.

That way, it's individual petals would only be either black or white and not a mixture of the both of them.

It was also the reason why it had to be placed in a special kind of box that isolated the energy in each petal, to avoided it from mixing up together.
