Giving An Apprentice Ten Thousand Times The Return: Being A Teacher Never Hides One's Self

Li Xuanfeng traveled to the Fantasy world and became the youngest Elder in Lingjian Mountain at the beginning, bound to the ten thousand times return system for apprenticeship.The system will return whatever is bestowed to the apprentice, and it will be returned after a certain multiplier."Ding! You have helped the apprentice increase five points of root bone, and ten times the crit return will get fifty points of root bone!""Ding! You passed on the ten-day Cultivation Base to your apprentice, and you will get a thousand-day Cultivation Base in return for a hundred times critical strike!""Ding! You gave your apprentice an earth-level middle-grade Cultivation Technique, and you will get a sky-level low-grade Cultivation Technique in return for a thousand times critical strike!" …"My dear disciple, today I will give you the mysterious Xin Tianjian as my teacher!""Master, what about you?""Me? I'll do whatever I want!" Li Xuanfeng said as he took out a magic sword that returned after a ten-thousand-fold critical hit from the system space. …after many years."It's fine that Xuanfeng Great Emperor himself is so strong, why are all his apprentices the ceiling among cultivators of the same generation?""Because my Master never hides his secrets!" The apprentices who have become giants in all parties said proudly.
