This time, Duan Yun was practicing locked in his own room.
As such, the three Murong brothers outside the room could only hear his roars but couldn't see how he was practicing.
Suddenly, electric lights flickered in the dark room, outlining a figure.
"When did he learn the moves of the Thunder God and Mother Sect?" Shen Ying wondered.
"I don't know. You're so close to him and you don't know, how would I know?" said the Murong brothers.
The flickering lights continued, and the shadow cast on the window paper, along with Duan Yun's roars, made the three Murong brothers feel the person was both maniacal and mad, even somewhat divine and demonic.
At least at that moment, Young Hero Duan seemed like Old Demon Duan.
After that, the room became quiet.
Shen Ying puzzled, "Is it over?"
"Maybe he failed to master it and took a rest because he was tired," Feng Ling'er said with concern.
"Perhaps," replied the Murong brothers.
After all, cultivation is never an instant success.
