"Junior Cheng." Sun Yi called when he saw Cheng Sheng sitting on the roof while looking at the deep chasm afar on the battlefield where Xi Ming and Xi Xing were, training the Shanliangde Sect disciples who have completed their training with Fei Yin, and learned from Fei Yinzi and Xi Ning about spells, talismans, and simple arrays.
Cheng Sheng turned and saw Sun Yi. "Senior." He called and moved aside for Sun Yi to sit beside him.
"Where is Fei Yin?" Sun Yi asked.
"Da shixiong replaced Xi Shi in the other battlefield where sect leader Sun, elder Fei, and elder Xi are." Cheng Sheng answered. He is referring to Sun Yu, Fei Lin, and Xi Ling, who were in charge of the other battlefield.
"I see." Sun Yi muttered.
Cheng Sheng looked at him. "Senior has something in his mind?" he asked when he saw that Sun Yi is silent.
Sun Yi smiled. "Is it so obvious?" he asked.
