A powerful wave of energy left Long Chen's Sword, slicing the entire Royal Palace in half from where he was standing.
The center portion of the palace disappeared entirely from the energy of the attack as for the rest; it fell apart as the building lost its strength, swallowing everyone that was hiding inside the Palace, including all the High Ranking members of the Palace.
Since most of the nobles were in the place which was attacked by Long Chen, they all died.
In one single day, the Empire of Esteria not only lost its Emperor and Empress, but it also lost its Ministers and all the nobles of this great Empire. There was no one left to lead the Empire anymore, signaling the fall of a great Empire.
It was the Empire Long Chen came to save with Mingyu. It was Mingyu's home that he wanted to save from war while helping her family, but with his own hand, he destroyed everything that could have helped the Empire survive, effectively destroying what he came to save.
