After the five of them agreed to become Shangguan Xiu's subordinates, it wasn't long before Shangguan Xiu took them out. Then, he often had them test some of the things they had developed outside, wanting to see if these inventions were actually effective.
In fact, Boss Ke wanted to say that these inventions could be tested inside the castle, and there was no need to go outside.
Because all the things they developed in the past were tested inside the castle.
However, Shangguan Xiu's words were orders. When he said to test outside, the five of them couldn't refuse, because Boss Ke had not yet found a way to remove the chips from their bodies, so they could only obey Shangguan Xiu.
The thing being tested today was a newly developed piece of equipment designed to allow humans to rescue themselves if they fall into the sea. It was a full-body suit that allowed the wearer to walk freely on the sea surface after falling into the water.
