As Huo Yuhao successfully completed the mission, the system issued him a blind box reward and also unlocked a new ability for him: Blind Box Level Assessment.
Just as its name suggested, this ability was specifically used to assess the level of unopened blind boxes.
For instance, after obtaining this new blind box, Huo Yuhao used this brand-new ability to test its level.
The blind box was assessed as C-rank, proving that it contained C-rank rewards.
Of course, he could also use this ability to test missions he had yet to complete.
For example, the mission the system had issued long ago: reveal Tang San's true nature to the people of the Douluo Continent.
The blind box for this mission was A-rank.
Then there was the mission Huo Yuhao had recently unlocked: win the New Student Competition.
The blind box for this mission was B-rank.

But in reality, once Huo Yuhao obtained more missions from the system in the future, he would need to select missions with high rewards and low difficulty to carry out.
That would greatly improve his efficiency.
All in all, this function was still very useful.
Huo Yuhao played around with the new function for a while, testing the blind box levels of the box in his possession and all his missions.
Once he finished testing them, the system's voice rang out.

Congratulations, host! You have obtained the reward: Mysterious Soul Tool Master's Notes 1.
As the notification sounded, an ancient and mysterious book suddenly appeared within Huo Yuhao's Sea of Spirit.
Huo Yuhao briefly flipped through it and discovered that
