The Villainous Eldest Senior Brother and His Yandere Junior Sisters

After transmigrating into a harem novel, Lin Xiao became the villainous Eldest Senior Brother of the Azure Mist Sect.
By following the original storyline and being a pesky villain, he could eventually attain his reward of becoming immortal.
Having no other choice, he carried out his duty as a villain conscientiously. He would tease Fourth Junior Sister, steal Third Junior Sister’s clothes and spike Second Junior Sister’s drink.
Finally, the day when Ye Chen, the male protagonist, joined the sect came.
Lin Xiao was exhilarated. According to the original plot, he would attempt to Ye Chen, be caught by his Junior Sisters, and be humiliated by Ye Chen.
Yet, to Lin Xiao’s surprise…
“Big Brother is too kind. The poison he has prepared is such a child's play. Let me show him how it’s done.” Second Junior Sister said.
“Kill Ye Chen! Kidnap Eldest Senior Brother! He is mine!” Third Junior Sister declared.
“Kill everyone! Let’s create a world with only Eldest Senior Brother in it!” Fourth Junior Sister exclaimed.
“My sweet disciple, he’s so cute even when he tries to poison someone furtively.” His beautiful master swooned.
Lin Xiao screamed internally, “Read the scripts, all of you! I’m the one who is supposed to be killed!”
