Previously, they were the trusted aides of Jia Tianba. Jia Tianba betrayed the Qinglong Club and was subsequently killed by Shen Qingcong. In their unwillingness to die, they maimed themselves using the "three knives and six holes" method to seek forgiveness from Ya Ting and Shen Qingcong.
With Jia Tianba previously being their lord, Shen Qingcong, for her own safety and to eliminate potential threats, directly commanded them to acknowledge her as their lord.
Afterward, she asked Ya Ting to arrange for them to receive treatment for their wounds.
Their wounds have since healed, but they had been waiting uneasily for Shen Qingcong to assign them tasks.
They feared being forgotten by Shen Qingcong, or even worse, being dismissed as useless pawns and being left aside with no chance of advancement.
They were not afraid of being used, but they were afraid of losing their value of being used.
