Everything your teacher has taught you is the real deal.

Looking at the first mission issued by the system, he fell into deep thought. "Within one month, recruit a new disciple and have them break through to the Foundation Establishment stage; the designated cultivation technique is the [Great Grade Heavenly Immortal Art]!" Lu Yuan: The Great Grade Heavenly Immortal Art? The Monkey King's technique? That first-rank fast-track method of the Three Realms, claiming three own years for Heavenly Immortal and five years for Golden Immortal? In one month, even a dog could break through to Foundation Establishment! Lu Yuan: This is a piece of cake!!! ... Chen Nanxuan lived a second life. In his previous life, he was a Tribulation Transcendence Great Immortal Venerable, but because his foundation was unstable, he died under the heavenly tribulation due to his greed for rapid progress. In this life, he must take it one step at a time, and for every realm, he must solidify the foundation before seeking a breakthrough! With the techniques of his past life in his heart, Chen Nanxuan joined the Daluo Sect. Originally, he just wanted to find any random sect to develop in peace; having lived again, he didn't need any special resources. When his master passed down the Great Grade Heavenly Immortal Art, Chen Nanxuan accepted it on the surface, but immediately tossed it aside. One month later, Lu Yuan looked at Chen Nanxuan, who was still at the third level of Qi Refining, and fell into a confusion. "Why aren't you practicing the technique your master gave you?" Chen Nanxuan: I, Chen Nanxuan, do things as I see fit; why should I explain myself to you? ... N years later, looking at the Daluo Sect's disciples who each did whatever they wanted, not a single system mission had been completed. Lu Yuan flipped the table. "Fuck all of you! Who wants to cultivate immortality, let them cultivate it! These fucking stupid missions can't be completed at all!" "Everything your master taught you are the real deal, and not one of you learns it, right? Get out! All of you, get out!"
