The Nirvana Fountain of Real Phoenixes lied deep within the volcano.
Ling Xian sat in a lotus position with his eyes tightly shut. He allowed the phoenix to attack him with real flames but he remained immobile and tall.
The flame of the pure-blooded phoenix will help him transform!
Though these flames were terrifying – enough to burn away his hair and for his skin to show signs of cracking, the phoenix's blood was providing him with liveliness and stopped him from being burned alive.
At the same time, it helped him transform.
The dormant spiritual energy wasn't all. His physical body and his soul were being nourished by the real phoenix's blood and he was walking towards being a true original level cultivator.
It wasn't hard to imagine how gloriously powerful he will be once he successfully transforms.
