What does it feel like to use one Bone Dragon as if it were seven?
If you ask Zi Liyuan, that would be absolute air supremacy!
So, without any hesitation, he summoned all the remaining boss-level Bone Dragons at once.
Then, controlling these Bone Dragons, he infused a strand of Dragon Soul into the altar to acquire skills.
In the recent aerial sniping battle, the Bone Dragon swarm had suffered heavy losses, with dozens turned to ash and no longer possessing bone structures, hence temporarily unsummonable. However, none of the Bone Dragon Bosses had fallen, which of course was a result of Zi Liyuan's manipulation.
The common hero template Bone Dragons were used as cannon fodder to ensure that the boss-level Bone Dragons would not die, thereby maximizing the delay.
At this moment, looking at the Bone Dragon Bosses, Zi Liyuan saw what seemed like an overwhelming swarm of Bone Dragon Bosses.
