Zhao Hai returned to the origin space and threw the interspatial bag into it. He had already checked the contents of the bag. There was nothing good in it. The weapons used by the two cultivators were no longer in the bag.
The reason Zhao Hai paid attention to the two weapons was because they could use the power of law, which meant that the two weapons were quite good. Zhao Hai even suspected that the two weapons were prizes given to the two people in the animal arena.
Don't think that any weapon can use the power of law. It's impossible. Ordinary weapons can't withstand the power of law at all. If ordinary weapons were used with the power of law, the weapons would be immediately disabled. However, the weapons used by those two people could use the power of law. After using the power of law, they were still intact, which meant that the two weapons were really good.
