By the time someone was discovered approaching, it would be too late to crawl to this spot without making a sound; careful movements couldn't be too fast.
As things had progressed to this point, a sense of ambition had unconsciously formed among everyone through their collective effort upon witnessing Tong Mingshan's achievements.
Initially, when Tong Mingshan obtained one or two Divine Fire, everyone felt it was irrelevant to them, thinking that the risk wasn't worth it. Later, when he obtained one or two more, at most, they believed what the Master had said made sense.
To some extent, they were still looking at it in the light of the Master's prestige, or out of no choice due to the pressure from the Master.
Only when they saw each success with their own eyes, and witnessed Tong Mingshan absorb ten Divine Fire, did the group truly realize from the bottom of their hearts what they had been collaboratively creating, and recognized the Master's brilliance!
