Starcrossed

Tianwai Peak was not originally a mountain from Inferno. It was, in truth, flown from the outside world and landed here.

And it landed on the Infernal Demon Dragon's territory.

The Infernal Demon Dragon had spent thousands of years exploring and researching on the mountain, and it finally found out that there was a hidden treasure vault at the center of Tianwai Peak.

The treasure vault was an extradimensional space that could not be seen and was located on another plane of existence.

After spending a few more centuries, it was finally able to force open the treasure vault.

When Jiang Fan led the Undying Crows to where the Infernal Demon Dragon was originally at, the Infernal Demon Dragon did not notice their existence as it was focused on the treasure vault.
