Tianyan Formation Disk, The Collapse of Time

Jiang Ming had now understood that the so-called Great Dao Alliance wasn't the rival of the Heavenly Demonic Beasts at all. Therefore, the members of the alliance could only remain hiding while furtively accumulating power. 

What Gu Cheng said about the need of sacrificing numerous Sea of Chaos to train up a military team was thereby nonsense.

Not long later, all the members of the Great Dao Alliance had rushed over. There weren't many of them, there were merely 240 of them.

There was a formation disk in the Palace of Fortune. It was called the Tianyan Formation Disk, which was left behind in ancient times. Once the members left their imprints on the formation disk, they could return easily by spending Hongmeng Coins.
