The main problem was that Li Yuanba's level was too low and couldn't harm the half-step great power Zhao Zhao at all.
Half-step great power Zhao Zhao felt his condition, with his injuries worsening during this rapid battle. If he waited any longer, Duke of Thunder would catch up.
When that time came, he still wouldn't escape the Duke of Thunder's attack, so he needed to take care of this big trouble.
A hint of madness flashed in his eyes; it wasn't that he had no way to deal with the Duke of Thunder.
This was his Grotto Heaven, and he had always been careful to maintain the energy stability within it, only mobilizing the energy in limited amounts each time.
Knowing there was a possibility of falling, he decided to risk his strongest attack and eliminate the Duke of Thunder first.
After the Duke of Thunder fell, even if he was severely injured, dealing with Li Yuanba wouldn't be a problem.
