After killing the Xuanyuan Dragon, the crew left Xuanyuan Cave.
Han Sen didn't feel very well, and First Day and Yun Sushang were injured. They couldn't keep going. They also had to carry out the dead bodies of the Xuanyuan Dragon and Ghost Claw Beasts.
The Xuanyuan Dragon's body was very useful, and it also had xenogeneic genes. They didn't want to waste it.
Han Sen cut open the Xuanyuan Dragon's head under Thousand Feather Crane's supervision. He took out a brain orb, which was the xenogeneic gene of this creature.
The brain orb was around the size of a fist. It looked like a black crystal. The strangest thing was that there was a Xuanyuan Dragon with wings inside it.
When Han Sen obtained the brain orb, an announcement played.
"Obtained Marquise Mutant xenogeneic gene. Insufficient Marquise genes. Cannot refine."
