"Why? It is good… if their strengths upgrade, right?" Chu Yang was at a loss as he asked.
"In short… it's not good," the Sword Spirit replied, "I can't tell you why it is not good since my memory is sealed. But, I can faintly sense that… it would be best if it doesn't happen. The best thing for them would be to solidify their cultivation, improve their aptitude, and make them accumulate the martial power one step at a time so that they eventually reach the peak.
