How Liu Wei went to meet the gang members had nothing to do with Zhao Hai. He did not go to meet them. Although he might be better at dealing with them than Liu Wei, Zhao Hai did not like dealing with them because it was not worth it. What Zhao Hai needed to do now was to teach the new members of bulei gang and help them improve faster.
Although Liu Wei and the others were very attentive in the education of the newcomers, there was no other way. Their own strength was very limited. When they taught their disciples, there were many mistakes. Those who were taught by them naturally wouldn't be very strong.
Among those people, Zhao Hai found a few who were quite talented. Of course, their talent was only relative. Compared to ordinary individual cultivators, their talent might be good. However, compared to the disciples selected by the big sects, their talent was far worse.
