Following the trail of clues, they discovered that the real traitor was Hua Dongliang's sworn brother!
The woman by Hua Dongliang's side had been secretly involved with him.
She was the one who leaked confidential information to Hua Dongliang's sworn brother!
The two of them had been colluding, using Hua Dongliang and reaping considerable personal gain.
Hua Dongliang was shocked and deeply hurt when he heard the news.
He had never expected to be betrayed by the two people he trusted the most.
In a fit of anger, Hua Dongliang led his men to arrest his sworn brother, who fought back desperately, knowing his treachery has been exposed.
In the intense shootout that followed, Hua Dongliang's sworn brother was killed, along with his sons, and the woman as well. Hua Dongliang was also wounded.
But before his sworn brother died, he cursed with his dying breath, swearing that his descendants would revenge themselves on the Hua Family and kill every single one of them.
