After Traveling Through the Qin Empire with His Best Friend, He Became Immortal

No heroine + genius + survival + Qin Empire + longevity + good brothers + all realms Su Qingyun and Wang Xiaopang traveled through the Qin Empire and split the Immortality Fruit into two at the beginning, so both of them gained immortality. After getting the cultivation techniques in the village, the two of them quickly reached the middle stage of foundation building. When the two of them were considering whether to go to Daqin Academy, they accidentally connected with their good brother Lin Hao in Blue Star. When they learned that Lin Hao was trapped in the fog and needed help to survive, the two finally embarked on a journey to seek immortality. As my cultivation level gets higher and higher, I always feel like someone is silently paying attention to me behind my back. It seems that I have been living under the surveillance of others. Moreover, the attitude of the people of the Great Qin Empire towards him was also very strange. As we see more and more, the fog surrounding the Great Qin Empire has never been cleared up. What secrets are behind the Qin Empire? Smart readers, come in and explore with the protagonist. (I can't read the introduction myself) Note: The author's writing is not good.
