Why Did the Promised Male Protagonist Turn into a Yandere?

[Multiple heroines + Shura field + dual systems + cultivating immortals + changing marriages + strategy and reverse strategy] Su Bai, who traveled through time for the second time, thought that his journey of cultivating immortality would be easier in this life. As a result, he traveled through time and became the sect's favorite with incredible looks. He was forced into seclusion every day by the female cultivator who confessed his love! Even the script is all messed up! Ye Fan, the male protagonist who cheated him in his previous life, was reborn as Ye Qingshuang, an iceberg female cultivator with white hair and red eyes, and became his top disciple? What's even more outrageous is that not only did she vow to "protect" him, but she also stared at all the cute junior sisters around her! "Master, stay away from them, they will be protected by me in this life!" "Qingshuang, you are already a girl. Isn't this inappropriate?" "It doesn't matter, feelings can transcend gender!" Faced with the rebellious disciple who was powerfully reborn, had his own system, and desperately wanted to bend all his disciples, Su Bai, who was equipped with the "Strike System", smiled. Than flirting with girls? Who has he been afraid of in his three lifetimes! No matter if you are a reborn boss or a yandere fairy, please keep your strategy value maxed out for me! However, the way Ye Qingshuang, the son of destiny, looked at him was becoming more and more strange? No? ! What about protecting the junior sisters from this "disaster" like me? Why did you join in yourself? There are also the gentle and lovely alchemist Luo Qingyi, the cute and lively talisman genius Jiang Yingluo, the cold and charming swordsman Mu Yunzhi, the shy spiritual planter Xia Zhiqing... Even the weird system Xitong in my mind started clamoring to materialize? Stop! Don't come over here! "Master, you can't run away~" x N This is a wonderful story about how to bloom peach blossoms in the world of immortality, but also to prevent the yandere from breaking up each other's homes.
