Just when Shen Xu wanted to say something, a shadow flew past them and attacked Dongfang Jing.
"Look out." He shouted.
Hearing the warning, Chen Yi reacted fast and pushed Dongfang Jing to the side.
Instantaneously, he unsheathed his sword and attacked the shadow.
However, his attack passed through the shadow and fell on the cave wall.
"Why didn't it work?" He muttered but didn't waste a breath.
Although he didn't know why the attack didn't work, he still swung his sword and attacked again.
Unfortunately, the result was the same and the shadow suffered no injuries.
"It's a nightmare beast. Use a soul attack." Zhen Yuan shouted.
At the same time, he condensed a soul dart and threw it at the shadow.
Barely a moment later, the nightmare beast dissipated and a black demon core fell to the ground.
"Thank you, Daoist friend Zhen." Chen Yi said, looking at Zhen Yuan with grateful eyes.
"Don't mention it." Zhen Yuan said and turned to look at the evil-swallowing cauldron.
