A web novel that I haven't finished reading before

I can't remember the name clearly, and the characters are the same. It was very good at that time, but I couldn't find it after I finished reading it. The male protagonist seemed to have reached the ninth level, but he couldn't reach the peak. Later, due to a misunderstanding, he gave his girlfriend 900 years of cultivation power. His girlfriend got 900 years of lifespan, but her cultivation power could only stay at 900 years. Later, when the male protagonist woke up, he found that he wasn't dead. He found that he had finally broken through the barrier and reached the top level of the Undying and Imperishable Realm. However, he was very unhappy. During these 900 years, his girlfriend kept searching for the male protagonist. It seemed that the male protagonist finally wanted to find the female protagonist in the last year. Oh, right, when the male protagonist came out, he felt a familiar feeling. When he came to the place, he found a group of people. It turned out that they were his subordinates who had a contract with him. Because of the 900 years of continuous reincarnation and the existence of the contract, their soul fragments kept reassembling. There was me in you and he in me. When they sensed their master... They knew that they had finally arrived.
"That's all I can remember. There are elves and magic. However, after his rebirth, although he reached the undying realm, he had no skills. He started practicing from inner qi. Please tell me if you have read it. I would like to thank you. If so, I will add 100 points. This book is very well written and the plot is fascinating."
