It Makes Sense for Me to Become Invincible by Practicing Unlimited Critical Strikes, Right?

A fantasy world filled with monsters. Ye Yun traveled through time and gained an unlimited critical hit system. Others gain nothing for every effort they put in. Even if Ye Yun worked hard, he could reap infinite critical hits with a multiple of more than ten times. If you take one pill, the effect of the pill will be ten times as critical, which is equivalent to the effect of eating ten pills! Practice martial arts once, and the effect of practice will be a hundred times more critical, and you will gain the insight of practicing martial arts a hundred times! After a day of hard training, the training effect will be a thousand times more critical, and the martial arts cultivation level will increase for three years! One day, when Ye Yun stepped onto the top of the heavens and the world, the powerful and powerful people of all races were dumbfounded. Everyone works equally hard, why do you become invincible so quickly?
