Xu Yanwu had once read about this part of Fu Hua's past in the Divine Key Secrets before he transmigrated.
When Fu Hua... or rather, Hua, was sixteen...
Himeko, the captain of the former Fifth Squad, was corrupted by Honkai Energy and became the Seventh Herrscher.
And Fu Hua was the only survivor at the time.
Afterward, because of this incident, Fu Hua was called the Witch's Companion by the other soldiers and was ostracized.
Even after something like that happened, Fu Hua did not give up on her life as a warrior. She continued to persevere.
And Himeko, as the Seventh Herrscher, the Herrscher of Flame...
One week after the Herrscher of Flame was born, she turned all of Australia into a sea of fire.
It was precisely to fight the Seventh Herrscher, whose destructive power was the greatest, that Doctor MEI proposed the Fusion Warrior project.
By integrating the DNA of Emperor-class Honkai Beasts into human bodies, they could create super soldiers with natural resistance to Honkai Energy and physical abilities beyond those of humans.
And to support MEI's plan, Kevin... Kevin himself volunteered to become a test subject for the project.
The genes of Parvati, an Emperor-class Honkai Beast capable of controlling ice and snow, were integrated into Kevin's body. Because of that, Kevin gained the ability to control ice and snow.
Kevin became the first Fusion Warrior, and under Kevin's lead, Himeko, the Herrscher of Flame, was personally killed by him.
After that, the core possessed by the Herrscher of Flame became the core of Kevin's weapon, Holy Judgment of Heavenly Fire.
And because of his resistance to Honkai Energy and his ability to control ice and snow, Kevin became the only person capable of wielding the Divine Key, Holy Judgment of Heavenly Fire.
