The answer is obvious.
Many have broken their heads in pursuit of this so-called true transmission, many have schemed and struggled to obtain even a slight hint of Sword Intent, and this kind of true transmission transcends the concept of cultivation realm.
Just like that day, Liu Tangxi, far from being Lan Tianyong's match in terms of cultivation, was able to repel him with a single sword strike and even forced the Great Elder of the Taixu Sect to lower his head and admit his mistake.
Liu Tangxi only mentioned to Jiang Feng the story of how Taiyi True Man cultivated, comprehended the Dao, and ascended to heaven, never revealing that she herself was also on this path.
Faced with such a true transmission, how many people are itching to make a move?
Jiang Feng is but a rootless weed, without familial support or anyone to lend him a hand, relying solely on himself.
