The sinister black wall was actually covered in runes. Some of them were identical to the runes Chen Fan had seen on the immortal bone along the Ancient Immortal Road. Little Golden Monkey had once gnawed off a piece of that immortal bone, which Chen Fan had kept.
At this moment, Chen Fan turned his Storage Ring again and took out that piece of immortal bone. Comparing the runes carefully, he found that they truly matched a section of the runes on the black wall exactly.
They were all Supreme Restrictions. What did that mean? This wall was absolutely not something Chen Fan could force his way through with brute strength. Supreme Restrictions were restrictions used by immortals; their mysteries were impossible for ordinary cultivators to fathom. Even Chen Fan had once forcibly deciphered a single rune with his Nascent Soul Late Stage cultivation—but that one rune alone had suppressed him until he spat blood.
