Reincarnation!
The little girl Lin Xian'er was a reincarnation of some almighty figure. It's just that this was not as simple as it looked to be.
In simple words, her existence was similar to Ye Chen, who got reincarnated because of the system.
Of course, the little girl had no such heaven-defying thing; if she did, she wouldn't be this unknown and only become a genius now.
There were few answers to this and one of them that Ye Chen believed was that her previous self used her soul as a medium to reincarnate.
This was really a dangerous process, and the chances of reincarnating were low. Unless someone was forced to a dead end or had a ridiculously strong soul, no one would try this.
But from how the little girl was acting, the chances were high she did this because after reincarnating through this method, their soul would be divided into two.
