After 30,000 Years of Refining Qi, Master, You Are Truly Invincible!

[System+Empress+Apprenticeship+Multiple heroines] Qin Yu was originally an ordinary person in this world, but in an unexpected encounter, he accidentally traveled to the mysterious Holy Word Continent. To his surprise, he actually got a sign-in system. However, time flies by and 30,000 years pass by, but Qin Yu is still stuck in the Qi refining stage, unable to make any progress. This made Qin Yu have to suspect that his system was a waste system. And Qin Yu, who knew that he was only in the Qi refining period, could only continue to fool his apprentice every day. But I never thought... "What? I was the God Emperor in my previous life!" "What! Can all my disciples jump to the challenge?" "The cow I raised is actually a fairy beast?" "The chicken I raised is actually a phoenix in the fairy world?" "Do I still have the incarnation of the Immortal Emperor?" Qin Yu's disciples could only say helplessly, "Master, you are truly invincible!"
