Darkwing Tiger

A terrifying late eighth rank Magical Beast called the Darkwing Tiger. It possessed an ancient bloodline, and had inherited a flying beast's bloodline that gave it great speed.
Although it was also an eighth rank Magical Beast, it was much stronger than the previous ones. It was a perfect embodiment of the phrase ‘like a tiger that has grown wings'. It was a combination of both speed and power.
In truth, the Darkwing Tiger's defense was shockingly great. Even this sudden attack would normally be unable to break its tough outer hide, and even if it did, it wouldn't cause such a huge injury. The only reason it had worked was because the Darkwing Tiger had gathered all its defensive energy to its wings.
As for the Darkwing Tiger, its energy stems from its Neidan. Even once its head is cut off, it won't immediately die. It will have one last breath to unleash all its Neidan's energy in one sudden explosion to bring down its killer.
