The Guanyun Dense Seal.
After receiving the Runic Inscription's inheritance, Chen Lin figured out what it was used for.
He was bitterly disappointed.
The inscription had neither offensive nor defensive properties, nor even any support abilities. Its sole purpose was to activate that "gold bar."
No.
It was not a gold bar.
That thing was a key. This inscription could activate it to open the so-called Treasure Vault.
Chen Lin felt thoroughly frustrated.
After pouring in so much effort and wasting so many materials, this was all he had obtained.
It was a losing deal through and through.
While he was comprehending the inscription, the spirit liquid dripped into his Heaven-Opening Eye had been rapidly consumed, leaving it unable to nourish the seed of his Divine Ability. Had he used all that spirit liquid to improve his Heaven-Opening Eye instead, he might have raised it by a minor level.
By now, nearly all the materials in the city had been swept clean. To refine more spirit liquid, he would have to wait until the monster was dealt with, then search elsewhere.
He shook his head.
Chen Lin put away the pages.
Whatever the case, obtaining this Spirit Liquid Formula was still a considerable gain.
Moreover, the formula employed a higher-level refining method. If he could unravel it, it would greatly benefit his future pill refining.
He set aside his stray thoughts.
Chen Lin took out the "golden key" again.
He activated his Natal Runic Inscription, condensed the Runic Puppet into the Guanyun Dense Seal, and sent it into the key.
Nothing happened.
He frowned.
He tried again.
But the result was the same.
The key showed no response whatsoever to the Dense Seal's energy, not even the slightest abnormality. It was no different from using any other kind of energy.
