Lu Xia for the first time felt that his clan was being belittled by a brat who came out of nowhere and started saying nd doing shitty stuffs just to garner attention.
Well, he couldn't say anything more when he learnt that Lu Heng one of his top clans men used the give and take berserk art, a forbidden technique of the clan to fight with Yao Wang and was defeated while still in the berserk form.
He knew very well what the give and take berserk art does, it boosts strength and battle power and also Increase defense very well and yet, Lu Heng was defeated.
Not only that, his clansmen were defeated as well.
Just one demon wiped out a whole branch of the Immortal squadrons clan and to make things worst, that family wasn't a minor Branch family and was instead one of the strongest Branch family the Immortal squadrons ever had starting from the ancient times.
Their Battle might in wars and their intelligence.
