It was not that they did not want to continue the fight with Wang Baole, but the combat abilities that he had showcased were simply too superior. Coupled with the fact that the four major Dao Colleges were allies, the consequences would be dire if a life-and-death battle were to break out between them.
Another reason was that once the Spirit Root had been absorbed, there was practically no way of snatching it back, unless certain cruel methods were used. However, that was a taboo, and the students from the four major Dao Colleges were ultimately students who did not have any deep-seated hatred toward each other. Therefore, few would want or dare to do such things.
As a result, during the battle just now, both Wang Baole and the six of them had exercised restraint despite competing with each other for the Spirit Root. They all showcased their trump cards, but the most that they would inflict was injury.
