Tang Shengyi's expression changed slightly as he said, "A predecessor of our Tang Sect is being held prisoner within this back mountain, and the voice just now was emitted by him."
"If he is a member of the Tang Sect, why is he imprisoned here? Did he betray the Tang Sect just like your second uncle?"
As Xiao Yifeng spoke, his X-ray vision activated, instantly penetrating the back mountain and revealing the situation inside the cave.
In the cave, eight thick Profound Iron Chains bound a man with grey hair who appeared to be in his forties or fifties.
The man's expression was one of extreme madness; he alternated between bursts of laughter and angry roars. He exuded a powerful aura, but a special poison had been administered to him, suppressing his strength. Otherwise, the eight Profound Iron Chains would likely struggle to contain him.
