After mulling over for a moment, Shen Luo suddenly lifted his palm, slapping it towards the crack of the stone door. A cluster of water vapor in the void was drawn over by him, forming a fist-sized water ball, and was smashed over.
With a soft "bang", the prohibition inside the stone door was again stimulated. On the stone stele beside Shen Luo, a faint and unimpressive blur of light lit up.
Shen Luo had been staring at the stone stele all along, hence he could see clearly, discovering that what emerged from that blur of light was a rune mark he had never seen before.
"If I manage to break this mark, wouldn't that mean I have cracked the prohibition?" As he watched the mark disappear, he muttered to himself.
Previously, Shen Luo had not learned how to break prohibitions. The ability to find the Nameless Heavenly Book was largely due to luck and fortune. Now, this was the only option he could attempt.
