Mighty Sirius
Long Tian was an existence that was only a little over 2,500,000 years old, which was quite short compared to the leaders of the other seven factions of Higher Existences; even some of the subordinates under his command were his elder in terms of age.
At birth, Long Tian was already a powerful peak Second Order dragon and it took him no more than a decade to fulfill his breakthrough quest to become the youngest Third Order dragon in the history of the dragon race.
To advance from the initial Third Order to the peak of the Third Order, Long Tian took approximately 200 years and finally took about half a century to complete the challenge that the Soul Record raised in order for him to continue advancing further.
From the initial Fourth Order to the peak of that same stage, Long Tian took about a thousand years and it was at this point that the talented and proud dragon met his first major obstacle.
