Fantasy: After Reaching Full Level at the Beginning, I Failed

Lin Xiu traveled through the world of immortality, struggled for hundreds of years to barely build a foundation, and became frustrated and decided to completely destroy it. Just when he was about to return to the countryside to retire, the [Strongest Master System] was activated! You can bind as soon as you accept a disciple! The apprentice practices, and the host receives a hundredfold feedback! The apprentice has an epiphany, and the host simultaneously gains enlightenment! Lin Xiu's eyes lit up: Isn't this just asking someone to act as a trainer? Can I become an immortal just by lying down? In order to dispose of the goods safely and efficiently, he decided to recruit those "waste" that no one wanted as apprentices. The first apprentice was a girl whose engagement was broken off and her spiritual roots were completely destroyed. Lin Xiu threw her a copy of "Basic Breathing Techniques" and said: "The truth is simple, just understand it yourself." [Ding! The apprentice watched the starry sky at night and suddenly realized the "Immortal Body of the Stars" from the "Basic Breathing Technique"! Return the "Universal Sutra" to the host! Lin Xiu: "?" The second apprentice is an orphan girl who has a blood feud and is corrupted by demonic energy. Lin Xiu handed her a hatchet: "If you have a sword in your heart, everything can be a sword." [Ding! The apprentice chopped firewood 30,000 times and understood the supreme sword intention to "kill gods with one thought"! Return the "Zhuxian Sword Intent" to the host! Lin Xiu: "??" The disciples he accepted were all future empresses, demon lords, and demon saints... They were involved in life and death, and they forced Lin Xiu to become the best person in all eternity! One day, a giant from the fairy world came down to earth and tried to take Lin Xiu's apprentice by force, but he yawned and crushed him with one finger. The disciples were shocked: "Master! Didn't you say you only know how to farm?" Lin Xiu looked innocent: "Yes, I am really weak as a teacher, and I rely on you to lead me. So, who will cook dinner tonight?"
