Where is the bond between the first emperor and Hades?

"The Last Valkyria" began with a draw between the Emperor and Hades.

In the "War between Man and God", the two sides were the First Emperor and Hades. In the previous plot, the first emperor showed amazing strength, took off his blindfold and confronted Hades seriously. But as a generation of "hades", Hades was not an ordinary person, and stabbed the first emperor in several fights. Fortunately, the first emperor was not substantially hurt.

In this story, the first emperor released new moves and easily suppressed Hades. Although the power of the new action is amazing, it also has side effects that cannot be ignored.

Many fans can't accept that "injuring one thousand enemies and injuring 800 enemies", because even if this move is powerful, the best ending is just "mutually assured destruction" with Hades. In other words, this battle is likely to be a draw.

A brief comment on the battle between Qin Shihuang and Hades;

As long as the war is a draw, Hades can find a place for the Greek god system, and the first emperor can also keep constraints and win-win. The author can arrange for one of them to kill the other party first in the battle, and then the killed party will launch special abilities before his death, resulting in the death of the other party, so that both of them die, which should be a draw.

Although there has never been a draw in the previous battles of Valkyria in the final, there is a first time for everything, and now the whole Twilight of the Gods is allowed to have an average situation.
