You're Not Ordinary? Bro, How Did You Become an Immortal?!

My name is Ye Tian, and I have terminal liver cancer. But I’m still young, and I have a little sister to take care of. I don’t want to die just like this. If modern medicine can’t save me, then I’ll abandon materialism and search for a way to become an immortal! My name is Ye Xuanyue. I have a brother who loves me dearly, but he disappeared a while ago. From the diary he left behind, I learned that my brother was searching for a way to become an immortal. But how could immortals exist in this world? My brother must have gone mad! No, I have to find him as soon as possible and pull him back from the brink of madness! Following the diary he wrote, I traced my brother’s steps to the places he had explored. But after one strange experience after another... The Five Great Immortal Clans’ Willow Immortal, Peach Blossom Spring Village, the zombie groom of western Hunan... It turned out I was the ignorant one all along! Immortals really do exist in this world! There really is a way to become one!
