On the rooftop, Qin Guang reflected on the recent battle at the warehouse.
He was unaware of the conversation Jiang Qingxue and Qi Na were having in the bathroom downstairs, let alone that Jiang Qingxue intended to include Qi Na in his harem group.
Qin Guang recalled that during the battle, from a distance of a hundred meters, he had penetrated an Inner Strength Master's skull with a single marble.
It is known that the skull is one of the hardest bones in the human body.
It protects the most fragile part of the body, the brain.
The bones of an Inner Strength Master are incomparably stronger than those of an ordinary person.
At such a distance, most handguns would struggle to pierce the skull of an Inner Strength Master.
This would have been impossible for Qin Guang before he took the Innate Qi Boosting Elixir.
