Lei Xi had at that time been very young, and hidden behind the rocks that were alike to miniature mountains in the garden, had suddenly witnessed his own mother tied up and held down by several eunuchs in the backyard, with the Empress and her lady in waiting following behind.
Within the lady in waiting's arms, was a blood covered little infant.
That infant was the Fourth Prince who had just been brought into the Empress Palace, Lei Fan. Lei Xi had been overcome with terror then, seeing his mother being bound up, he had wanted to rush out. But he realized then that as a tiny little prince like himself, even if he had run out to confront them, he would not have been able to achieve anything and so he had endured the consuming fear eating at him as he stayed hidden.
