I Am Only in the Qi Training Period, How Come I Am Invincible in the World?

(Invincible text + Immortal cultivator's dimensionality reduction attack + multiple female protagonists) Qi Yun came from the world of immortality. Before time travel, he was just an ordinary foundation-building monk. After time travel, he adhered to his principles in the world of immortality, kept a low profile and practiced silently. In this world, the spiritual energy has just begun to recover. The spiritual energy is strong but the path is not obvious. Everyone in the world is struggling to find the extraordinary path. Controlling ghosts, ancient martial arts, Taoism, supernatural powers, controlling beasts, psychic mechas, genetic warriors... Qi Yun was dazzled by all kinds of extraordinary powers, but in the end he discovered that he was already invincible in the world as a young monk during his Qi training period. What's even more outrageous is that Qi Yun is curious why he has kept such a low profile, but Miss Sakura, the ancient martial arts genius, the beautiful mecha master, and the mysterious female ghost king all take the initiative to come to him? (This monk is obviously super powerful but too low-key) (I just want to know about your extraordinary path. Why are all the ladies posting here?) (The main plot is the recovery of spiritual energy, the exploration of supernatural power by various forces, and the daily love life of the urban harem?)
