Why did KINOMOTO SAKURA in Fantasy City become an ember? Are Sakura Kongshi and Yan Tiane the same person?

Sakura Kongshi competed with Kassel for the throne because he wanted his younger brother to live freely. Later, he was killed by his brother Castle. KINOMOTO SAKURA's last wish when he died was to break the blade Syracuse that imprisoned his brother. After rebirth, he became the prince with the highest spiritual talent of the fire clan, clinging to the wishes of previous lives, thus changing from a broken-edged Syracuse to a broken-edged Syracuse. When I finally saw my brother Castle commit suicide, I suddenly remembered the memory of my past life. Finally, I took my brother's body and committed suicide with Castle.

Therefore, releasing cherry blossoms is the death of heaven, and the death of heaven is the release of cherry blossoms.
