When the one thousand and first Thunderbolt Ropes merged into the Imprisonment Cage...
"Boom~" A flash of lightning tore across the sky, and the Imprisonment Cage suddenly started to shake.
The entire black cage became more solid, as if it could suck in one's soul. At the same time, three new characters appeared beneath the characters for "Imprisonment" on the wall.
The fourth level!
"I knew it!" Shen Zhui felt a touch of emotion. He didn't know who created this Thunder God Technique, but it was being passed down in such a manner.
From his recent experience, Shen Zhui now knew that apart from the characters for "Imprisonment", only he could see the six characters of the fourth level of the Thunder God Technique which seemed to appear through a unique spiritual sense.
After breaking the third-level limit, every additional rope would reveal three-letter words. Shen Zhui guessed that once these words fully appeared, the complete method of the fourth level would emerge in his mind!
