Hard Work Really Works

Three years, and another three years, do you know how hard it was for me to find sacrifices? It was not easy to find all the sacrifices without being discovered. But can you tell me why, why even the person who guards the tomb is so strong? I, Chen An, am a person who has traveled to the immortal world, and I have the same background as the army of time travellers, and I am an orphan. Of course there is also a system, a lottery system. But why is it so confusing? Every time you go to a different world, you will draw a prize. PS will be updated randomly. This novel and its characters are purely fictitious.
