After receiving this news, Chen Yang first let Chen Xuan guard the city while he came to the Land of Evil Demons, a desolate place.
After ensuring that there were no humans or demons around, Yang Chen released the red dragon.
The reason why he chose the red dragon was simple. The red dragon's bloodline was that of a spirit beast, but it was because it was congenitally deficient.
When the Red Dragon broke through to the Demon Sovereign Realm, Yang Chen had already used the Dao Integration Pearl to make up for the Red Dragon's congenital deficiency.
Now that his red dragon bloodline had reached the level of a spirit beast, he had some energy left to upgrade his bloodline.
After releasing the red dragon, Yang Chen opened his right hand. The Dao Integration Pearl emitted a seven-colored light and slowly appeared on Yang Chen's right palm.
"Dao Integration Pearl. The Red Dragon's cultivation will be raised to the Spiritual Venerable Realm."
