Yang Zhen had initially thought that members of the Ancient Life Sect were all as enlightened as Gong Sanhe, a fairly decent old man. He was more than willing to interact with him.
Who would have thought that this old man with white hair would suddenly step forward, accusing him unceremoniously. If Yang Zhen genuinely had no ideas to put forth and wasn't qualified to express his views at this juncture, that would have been fine.
The key point was that he did have an opinion regarding the ancient altar handed down from remote antiquity. Not only did he have an opinion, but he could also thoroughly analyze the altar and even temporarily suppress the eruption of the Nine Dragons Que Flower region.
Under such circumstances, being reprimanded by an old man he didn't even know provoked Yang Zhen, no matter how good his temperament was.
Moreover, Yang Zhen wasn't exactly known for having a good temper in the first place.
