Of course, Zhao Yu was concerned about his father-in-law's safety. So, when he found out the hiding place of the diamond, he had already quietly begun his counterattack plan.
First, he easily used the bone shrinker to break free from the rope.
Next, he released four stink bombs in a row, and they were thrown at the places where the guards were. Since the hall was an open space, he knew that the stink bomb might not be able to knock them out, but it could at least interfere with their movements.
Secondly, he also used a new device called the invisible gas mask, which was successfully used by Lee Bencheng and the others.
Although these people could not be considered his true companions, at least they were on the same side in the face of a great enemy. As the saying goes, there's strength in numbers. Zhao Yu had to make use of these people's abilities to help him.
