Drop of celestial blood

When Bai Yun woke up the next morning, it was already noon, so he directly opened the store. And just as he expected, the servants of the Hei clan were standing in front of his store not letting anyone in. In response, Bai Yun just sat there and did nothing. To everyone else, it looked like Bai Yun had given up. But in fact, he was slowly perfecting his plan.

A while later the leader of the city guards came to collect the city lord's saber. Other than him no one else came in for the rest of the day.

After Bai Yun closed the store, he went up to the training room. He was going to crack the formation on the ball cap.

It took Bai Yun another hour to crack the formation. Bai Yun was surprised to find that inside the ball was a single drop of blood.
