The main character of this novel had a tower that could be stored inside and shrunk to the size of a speck of dust. Had the main character used it many times in times of crisis?

There was a novel where the protagonist had a tower. The tower could fit inside and shrink into dust! Many times, the protagonist had shrunk into dust to save his life! That pagoda could allow people to cultivate! In the beginning, only one level was opened. The protagonist seemed to have a fiancée who was the daughter of a secular emperor. She seemed to be a princess! But it seemed that the emperor had broken off the engagement or something, but he was not sure. However, I remember that the main character sneaked into the palace once and ran into the princess's room. At that time, he saw a woman on the bed and planned to do it with her. In the end, he found out that the woman was the princess's mother, one of the emperor's concubines. Then, he directly brought her into the tower to vent his anger! Later on, when the protagonist returned to the palace after his cultivation had increased, the woman even used the protagonist's power to teach the emperor's other concubines a lesson! This is the only thing I remember clearly! There seemed to be ascension after that! It seemed that he had obtained a puppet before he ascended. That puppet was a woman. It seemed to be from the Upper Realm. I promised him to fulfill his wish. I seem to have forgotten a few times. After I fulfilled it, I ascended back to the Upper Realm! He wondered if this was the same novel as the previous one.
