Yang Lujia was quite satisfied with Long Sheng. Other than he was unyielding towards others, at least he had sympathy with his son and was even prepared to sacrifice his life for him.
Very unlike someone he knew in the past.
Long Sheng was a very prideful dragon. He had lived longer than even the Phoenix Ancestor herself. They were considered to be peers with Gu Tian who had lived even when the Temporal Lords were not yet at their peak in the present. His old age made him feel above all others and exert dominance when necessary, just like what he did in the Fiend Emperor Palace.
Moreover, Yang Lujia thought that the matter of Gu Tian betraying this old dragon, his 'old friend' was not as simple as it seemed on the surface. It was as clear as the sky that Gu Tian's plan had been implemented along with so many other plans in different territories.
For example, the Holy Light Palace and his disciple's demise.
All of these might be connected.
