The reason the chains were shaking and pulling tight was all due to the struggle of Donghuang's original source.
It was unknown what materials the chains were made of. They were extraordinarily robust. The power emitted by Donghuang's original source was enough to burn the Innate Dao Sovereign to ashes, yet it was no match for them.
After a long burning, not even a mark was left. The chains still firmly locked Donghuang's original source, leaving it unable to move.
Boom! Boom! Boom!
After a while, the power released by Donghuang's original source grew even stronger. From afar, Jiang Chen felt waves of heat surging, causing his body to ache.
Hum... Hum... Hum...
The intense reaction of Donghuang's original source seemed to have angered these chains. Their bodies started to glow, giving birth to mysterious runes flowing on the chains.
