Moreover, the most important thing is, according to the academy's regulations, as the former Head of the Institute, as long as one can maintain a draw in battle, it counts as a victory. The same rule applies to the challenge system for grade segment leaders.
In other words, as a former Head of the Institute, although Lan Se lost, she still has a chance to take back the throne and can continue to challenge Po Kong. However, the difference is, if Lan Se wins the second round, then Po Kong will have the right to challenge again, and the victor of the third match will be the definitive chief.
Simply put, it's basically best two out of three. Lan Se has already lost one round, and it's up to her to initiate the next challenge. If she loses the second round as well, she will completely lose the opportunity and no longer be qualified to challenge. But if she wins, she must take part in the third match. That is the challenge rule of the Institute's Head of the Institute.
