Lind recalled how a heart demon had several effects on him, chiefly an explosive increase in power, but it came at a severe price. He had barely skirted Qi deviation and the crippling of his body.
What had happened to Fey that she had such a heart demon?
Had no one noticed?! Qing was not the sole expert and she had often spoken of her seniors being very competent. Lind pushed his anger aside as Fey pulled out her sword.
He realized her heart demon had allowed her to reach the peak of Sky Realm but until confronted with it, he had not even realized the problem. Her potential had been enormous, enhanced by his elixirs and teachings, but the most she should have reached safely was tier 5.
A sudden memory came back to him.
