This was also a mini grand affair that Mystic Sun Immortal Emperor had organised. He put up 99 different great void immortal treasures at once, established the immortal designs and opened the challenge to the floor for anyone to decode the immortal designs. For each attempt, one would have to pay a certain fee first.

If they failed to decode, the Spirit Ascension Pills they paid would have been in vain.

To stop an overly strong immortal king like a 9-Heavens immortal king who had the ability to decode all the immortal designs, from causing a scene and decoding all the immortal designs, there was a limitation in cultivation realm for each immortal design. For example, Terminal Ruins Immortal King believed the immortal design for the Thunder Flame Immortal Emperor's Celestial Pillar would be set as 4-Heavens immortal king and below.

At the same time, it would suggest that the Mystic Sun Immortal Emperor believed most of the 4-Heavens immortal kings couldn't decode this immortal design.

Since he was the one who established the limits, he definitely wouldn't be disadvantaged. He should have a clear idea of the tier of immortal king required to decode a specify immortal design. Only those...
