Zhang Sanfeng is skilled in martial arts, and once appeared in Jin Yong's novels "The Condor Heroes" and "The Dragon Slayer in Yi Tian". Zhang Sanfeng is a master of enlightenment and the founder of Wu Tang School. Although Zhang Sanfeng is not the protagonist of these two novels, he can only be regarded as the master of the leading actor. But because Wu Tangmen was suppressed by Zhang Sanfeng, many other sects were afraid.
In addition, his apprentice, Zhang Wuji, is very powerful. Although it is said that shine on you is better than Blue, in fact, many details in the novel are illusory and exaggerated. Generally speaking, Zhang Sanfeng is indeed worse than Zhang Wuji. If it weren't for Zhang Sanfeng's advanced age, I think he would be better than Zhang Wuji at his peak.
And why does the emperor want to find Zhang Sanfeng? Who is the emperor? Basically, it is written in history that the emperor recruited various Taoist priests to refine Dan medicine in pursuit of immortality. So compared with those Taoist priests, Zhang Sanfeng is the real master. After living for so many years, he must know the way to live forever. Those Taoist priests only get a few bottles of medicine to fool the emperor. In fact, most people know it in their hearts, and the emperor naturally understands it. It's just that the emperor is in a hurry, so he says he is willing to give it a try.
However, facts have also proved that there can be no such thing as immortality in the whole history. Even Qin Shihuang, who worked so hard that year, eventually became a scorched earth. Thinking about immortality, it is better to exercise more and eat more healthy food as usual, which is feasible.
