Bloodline fusion.
This is not an unfamiliar term to many of the new generation in Ancestor Dragon City, especially after the great war over two hundred years ago, when Ancestor Dragon City almost fell and humans were nearly annihilated.
And the starting point of it all was due to bloodline fusion.
In the Underground Palace City within Hell Arena, which is the darkest corner of Ancestor Dragon City, the nearly extinct phenomenon of bloodline fusion can still be seen occasionally.
Because most of the people in Underground Palace City are war slaves deprived of freedom, merely in the Duel Arena, many war slaves perish daily in life-or-death battles.
All rules within Ancestor Dragon City are completely absent in the Underground Palace City, where only fists and interests matter.
Sometimes in the Duel Arena, spies from the Ten Demon Hall emerge, and the true number of spies or those created by bloodline fusion in Underground Palace City is entirely unknown.
