Especially for older Qi Cultivators, although their cultivation bases are already immensely powerful—reaching the peak of Celestial Human or even the Feathering and Ascension realms—age makes them hesitant to easily take such risks. Otherwise, if they fail, their remaining lifespan is instantly depleted, and to die without having accomplished anything is certainly not worth it.
Moreover, the probability of failure is extremely high, which is why the vast majority of participants in the Tower of Illusion are young people.
Of course, some older Qi Cultivators still participate. For example, elderly ones who have reached the end of their natural lifespans and know they are facing a dead end want to take a gamble there, though the final outcome is rarely favorable.
