A contest of physical strength and intelligence

After hearing this, everyone's faces changed several colors.

At this moment, everyone realized a problem. If you come here to train, you won't be able to relax for a day. No, you won't be able to relax for a moment.

Even if you stayed in the house, someone would challenge you at any time, and you would not be able to rest well.

In other words, no matter where you live, be it a house, a tent, or a wooden house, you can't enjoy it. This was a blatant way of telling you that you're here to suffer and train. You can't even dream of sleeping well.

Yun Bilu knew that this kind of training was the harshest. It was like how all animals survive in the natural environment. It was a natural selection, and only the fittest could survive.

She didn't know who came up with this model, but she was full of admiration.
