"Kill!" Old Sun's aura suddenly surged, its explosive growth leaving Fang Chongyi dumbstruck. Not only Fang Chongyi-even Mu Jingfei, who was rushing over, froze.
"Old Sun!" Mu Jingfei hurriedly called out.
But Old Sun paid Mu Jingfei no heed at all. He charged straight at Tuoba Ao.
"Hmph, Sun Simiao, you've finally decided to stop holding back. But just because you kept something in reserve, did you think I hadn't? In the end, you still won't have a chance!"

"Watch out!" Old Sun hurriedly shouted.
But it was already too late. Mu Jingfei had charged right up to Tuoba Ao and sent a fierce punch at his chest.
"What?" Old Sun and Fang Chongyi's eyes widened
