Jin Yong's stupid man revealed the secret of giving up peerless martial arts and practicing bad martial arts, and the ending was embarrassing
There are many unforgettable characters in Mr. Jin Yong's martial arts, including heroes who are both wise and brave, smart and beautiful women, and wonderful plots of the struggle between good and evil, but there are also some unsightly characters in **, who gave up peerless martial arts, but conscientiously practiced miserable martial arts, and finally ended up a tragic end. In Jin Yong's writing, Cheng Kun is probably the stupidest of these people.
Chengkun background. 
In Jin Yong's ** "Heaven and Dragon Slayer", Cheng Kun is a big villain. Cheng Kun witnessed Yang Dingtian refining "The Great Shift of Qiankun", in this case, Cheng Kun had the opportunity to take away the cheats, but he missed the opportunity. Instead, he was obsessed with cultivating the martial arts of the Phantom Yin Finger, a decision that profoundly affected his fate.
Give up peerless martial arts.
The Great Shift of Qiankun is the most powerful martial art of the Ming Sect, and it is extremely difficult to cultivate, requiring extremely high internal strength, understanding, and wisdom. It is this difficulty that discourages Cheng Kun. Although he had the opportunity to get the secret book "The Great Shift of Qiankun", he decided not to practice this martial art. Cheng Kun's contempt and self-esteem that he gave up a great opportunity was obviously a very unwise decision.
Mingely's anger.
Cheng Kun didn't want to learn the Great Shift, partly because he didn't like Mingjiao. He thinks the organization is hypocritical, benevolent, and unworthy of him learning their martial arts. However, these prejudices and hatreds led him to ignore the great value of the Great Shift and the great power he could gain.
Grab the phantom finger.
Cheng Kun gave up "The Great Shift of Qiankun" and concentrated on cultivating "Yin Illusion Finger", which was another big failure for him. Although the Yin Illusion Finger is also a powerful martial art, it is obviously not as good as the Great Shift. The obsession and arrogance of the Great Shift made him unable to see a better choice, and his choice put him in an irreparable situation.
Tragic end.
Cheng Kun's unwise decision ultimately led to his tragic end. Although he had cultivated the Phantom Yin Finger for many years, he not only lost his eyes, but also all his martial arts at the Lion Killing Conference. It was the result of his own choices and arrogance, which he ended up paying a heavy price.
In Jin Yong's **, Cheng Kun is a character who contrasts sharply with other characters. Compared with Zhang Wuji and other major figures, Cheng Kun's choice and fate seem particularly stupid. Although Zhang Wuji faced many difficulties, he decided to cultivate the Great Shift, and finally gained great strength. In contrast, Cheng Kun gave up a once-in-a-lifetime opportunity due to his obsession with prejudice and arrogance, and finally ended up tragically.
Cheng Kun's story reminds us that sometimes you only have one chance, and you must cherish it and choose wisely. If we are led by the nose by stubbornness, arrogance and prejudice, we may end up with a tragic end similar to that of Cheng Kun. Through the character of Cheng Kun, Jin Yong conveys important lessons about cherishing opportunities, not giving up prematurely, and transcending prejudice.
Cheng Kun in Jin Yong** is one of the stupidest people in Jin Yong**, and his choices and fate are full of stupidity and tragedy. His story has become a cautionary tale in Jin Yong**, reminding readers to cherish opportunities, transcend prejudices, and avoid tragic endings similar to Cheng Kun. In Jin Yong's world, Cheng Kun has become a miracle of the century, a figure worthy of people's thinking and reflection.
