We Agreed on a Simulation, So Why are They All Showing Up at My Door?

(A love triangle, yandere, multiple female leads) Qin Li transmigrated to the Tianxuan Continent and became the illegitimate son of the Zhenyuan Marquis's mansion. He thought he was destined for a mediocre life. However, he awakened a "Simulated Life Experience System." The system promised that as long as he completed all the storylines, he could ascend to immortality! The only requirement was to leave each female protagonist with unforgettable memories, torturing them to the point of heartbreak, and dying in front of them. Qin Li, who was passionate about this in his previous life, was very skilled at it. In five years, he perfectly concluded all the scripts. He was once the master of a peerless female swordswoman, but in the end, he died by her sword. He was once a poisoner who captivated the empress, causing her to overthrow her kingdom, but he died by poison on the day he ascended the throne. He was once a demon, tempting the sect's holy maiden to betray her sect, but in the end, he was destroyed before her very eyes. He once saved a little fox in the Demon Continent and also helped an elf in another world. ... Qin Li thought he had successfully retired and was about to enjoy a carefree ascension, but the system suddenly disappeared. As a result, a female sword immortal who became famous a thousand years ago, an unparalleled empress who ruled the immortal dynasty, a female demon of the demonic sect, and even the nine-tailed demon emperor of the demon race, all came to confront him with astonishing cultivation.
