The reason why Zhao Hai wanted to use this method to send the liquid silver to the tool-refining Valley was that he was still very afraid of the dujie stage powerhouses.
Although Zhao Hai was very confident in himself, he knew that he was no match for the crossing calamity stage cultivators. At most, he could only survive the attacks of the crossing calamity stage cultivators without entering the spatial zone. It was impossible for him to defeat them.
It was precisely because Zhao Hai was very afraid of those powerhouses at the crossing calamity stage that he had to place the liquid silver in the weapon-refining Valley in advance. This was to prevent the powerhouses at the crossing calamity stage from finding out that he had directly put the liquid silver into the weapon-refining Valley from the spatial space. If those powerhouses at the crossing calamity stage found out the secret of the spatial space, it would be troublesome.
