Starting from the latest season of S5, players can get a king's seal every season and have a chance to upgrade the seal. The only requirement is to reach the position of the strongest king.
If a player reaches the position of the strongest king in S5, S6 and S7, his king mark will be upgraded three times. If a player reaches the position of the strongest king in S5 and S7 seasons, his king mark will be upgraded twice.
Extended data:
The glory of the king's method of winning the king's seal requires players to reach the position of the strongest king in the current season. After reaching the position of the strongest king, they will automatically get a king's seal when they update next season, and the number of king's seals will be superimposed with the number of times they reached the strongest king in the season.
The reason why there is still no seal of the king is that the issuance of the seal of the king is not immediate, and it needs to be settled in the current quarter and updated at the beginning of the next quarter.
