The king, the queen, and the concubines did not interrupt what Liu Yang and the princesses were doing inside the room. As the king had said he would need twenty-four hours, the group did activities for all that time.
After the time passed, Liu Yang and the princesses were called to the main courtyard to see all the inhabitants.
By the time Liu Yang said he was from another world, and the elders realized that the virgin princesses had lost their virginity, they immediately believed Liu Yang's words. For this was the proof that was irrefutable, for all knew that the princesses were virgins and no one could do activities in this world.
So when Liu Yang said that in order to get everyone out of the place it would be necessary to accept him as the new king. The crowd accepted willingly and without hesitation, the same was true of the royal family, they handed the crown to Liu Yang without a second thought.
