It's a Desperate Start, but My Understanding Is at Full Level

[High talent + not brainless + pretending to be a pig and eating a tiger + decisive killing + invincible genius + not a holy mother] Ye Changan, an orphan from a martial arts school, was reborn in another world, but he didn't want to be in a dead end when he opened his eyes, and the system was actually watching a show? Fortunately, Ye Changan managed to survive the deadlock and successfully activated the system. What? Are the exercises too difficult for them to learn? Don't panic, the divine light of enlightenment will directly fill your understanding, I only need a quarter of an hour! What? Is the sect's free technique too weak? Don't panic, work systematically, and deduce the remaining chapters into top-notch techniques for me. What? There are thousands of spiritual herbs and thousands of elixir prescriptions, but countless disciples cannot memorize them, so they are not destined to be an alchemist? Don't panic, give me a complete collection of elixir recipes, and I will give you a ninth-grade elixir saint in return. The disciples who were also practicing basic martial arts were unable to defeat Ye Changan. He also practiced the Tianxiao Fire Refining Technique, but it was not as powerful as Ye Changan. Also listening to the alchemy lecture, Ye Changan actually knew how to make elixirs for the second time? Even the elders of the sect have fallen into self-doubt. Is this handyman the real genius? Are all those carefully selected disciples useless?
