Next day,
Yesterday as Sam expected he did not get to cultivate as he was fully exhausted after fighting Livia, the Prince, and Emma. All three of them use their full power to fight with him so that they also have a better understanding of their power.
After the fight, Sam also helped them to understand how much they were far away from the limit of their grade. He also told them why they were unable to reach the limit of their grade that quickly. He also told them how they would feel when they truly reached the limit.
This would be very helpful for all of them, not just the three of them but even for the king and everyone present in the training ground to get to understand that.
