There were more than 7 million people. When these people first joined the 1st Legion, many of them were at the Golden core stage. They were not young anymore, which meant that their potential had reached its limit. In this life, they might not even reach the Yuanying stage, let alone the dujie stage.
It was because of this that many people in the 1st Legion chose other paths. If they didn't learn to refine weapons or medicine, they might end up as ordinary elders in their own sect. However, if they learned to refine weapons or medicine, their status in the sect would change greatly. Whether they were weapon refiners or alchemists, they had a high status in each sect. They would be very polite.
Zhao Hai had also noticed this a long time ago, so he had asked Cai to send some undead creatures away to give them some insights on refining weapons and medicine. These things would be of great help to them.
