Because if the parties involved do not understand the truth of many events, or it is inconvenient to fully record the facts to circulate them.
It is easy for some exaggerated fabrications to appear, gradually evolving into myths that people cannot regard as truth.
Take Wang Longhu, for example. Now, relying on his strength and speed, he can completely traverse the entire E Province in a single day.
Or wipe out an entire army equipped with only cold weapons, not hot ones.
Or leap across a mountain stream in one step, crush copper and iron with a palm strike, roar like thunder, and cross rivers on foot.
If these feats were witnessed, in ancient times they would be considered divine; even emperors would fear Wang Longhu.
So now, with Sun Biyun speaking in this way, Wang Longhu concluded that Zhang Sanfeng, Master Ghost Valley, and Laozi should all be people like him.
They have already entered the realm of the Three Elixirs and Four Breaths.
