Chapter 1517: After the Holy City fell...

The walls of the four kings expanded, and with the support of the vast amount of spiritual energy from the four golden cores Song Shuhang had in his body, he was able to unlock the Sixth Stage seal on his life-bound magical treasure, allowing it to exhibit a size at the True Monarch-level.

The size of the Holy City skyrocketed, reaching a height of over 100 meters.

A pagoda, war drum, bugle, zither, and war flag appeared.

The Impregnable Holy City came out with its own background music.

Although only the Sixth Stage seal had been unlocked, Song Shuhang's Combined Magical Treasure was still mainly composed of Eighth Stage materials, so it still possessed strength at the Eighth Stage.

Unlike before, Song Shuhang's main body did not appear in front of the Holy City. This time, the Holy City had come out to protect Island Master Tian Tiankong.
