Su Xin had attacked a sect under the protection of the Dugu Clan, on their own turf. That was a slap in the Dugu Clan's face, and it was something he had done deliberately.
At present, Su Xin truly had no way to move against the Dugu Clan. When he had destroyed the Qingcheng Sword Sect, he had been able to call on the Imperial Court and the forces of the Heavenly Court and Underworld. When he had wiped out the Su Family, the strength he had relied on had mainly come from the Su Family's collateral branches.
But now, facing the Dugu Clan, Su Xin had no power he could borrow.
Besides, the Dugu Clan's location and status were too sensitive. Even if Su Xin could find the strength to deal with them, Ji Haodian would never let him make a move.
So from the beginning, Su Xin had never planned to attack the Dugu Clan. As he had said before, this time he was merely going to give them a warning, much as the Dugu Clan had warned the Qingyuan Sect and the other sects that had been gossiping behind their backs.
People had to pay for their actions. The young disciples of the Qingyuan Sect and the other sects had spoken ill of Dugu Yan, so he had forcibly taken them back to the Dugu Clan, sealed their cultivation, and made them serve as slaves for ten years.
And since the Dugu Clan had tried to take advantage of the situation and snatch what Su Xin had in his hands, they could hardly blame him for coming to their door and slapping them in the face.
After that, Su Xin wasted no time. He went straight to more than a dozen sects under the Dugu Clan's protection
