This counts as a special trial—failure brings a heavy price, but success will only bring more rewards.
From the sheer power displayed by her extremely pure lunar energy, Yu Heng's potential is evident. The Boundary Breaking Organization is also watching; if Yu Heng truly achieves a breakthrough of Great Perfection in this area.
Then she may become the next 'Ban Long' within the Boundary Breaking Organization. Unfortunately, Ban Long from the organization was too gravely injured in the last battle to ever return to peak form.
If Zheng Yichen hadn't used that power surpassing destruction, the organization would have had many ways to restore Ban Long to his peak state. To overdraw life? That would have no impact whatsoever.
Up until now, the organization still hasn't developed a way to counteract that power.
Yu Heng's extremely pure lunar energy might be able to attempt some resistance; after all, pure energy is extremely exclusive.
