A Professor in His Later Years, Giving the School Beauty the Spirit Liquid at the Beginning?

(The male protagonist will become younger and younger + there will be many women who don't like him, so don't join him + the system + there are many school beauties) "I heard that the respected professor is dying." "Yeah, I heard that he gives resources to girls when he sees them." Li Chen's wife was the principal of the school. In order to help her break through, she was seriously injured, her energy and blood were exhausted, and she was about to die. Bite! The young system is activated. This system helps the host. As long as the host gives a gift to the opposite sex, it can be returned according to the degree of intimacy, helping the host achieve a double harvest in career and love. "The higher the intimacy? The more returns?" Li Chen's eyes widened slightly. From this moment on, he began to give unlimited gifts. Good old friend! Deliver! School belle! Deliver! The junior in the clan! Deliver! My wife's sister! Deliver! Goddaughter! Deliver! A few years later, Li Chen's love rivals all looked shocked, "Isn't he going to die a long time ago? Why is he not dead yet? He is getting more and more perverted."
