Bai Rouyun realized that since everyone was busy either with their own sparring partners or talking about the marrow-cleansing pill, she would not find a partner today.
As such, she only had one other option. This option was a bit riskier, but it was also more rewarding, so she did not hesitate at all. She went to the Mission Tower, took a simple mission where she had to kill some random low ranked mystical beasts, and take their beast cores and other resources back to the school in return for some points.
This method was much more rewarding, as the points could be used to exchange for various resources and access to some facilities, but she also knew that if she did not have some control of her limits, then it would be risky to fight it out with the mystical beasts.
These beasts were not like a sparring partner at the training ground, who would stop when an injury occurred. Fighting against mystical beasts was always a question about life and death.
