"The Candle Dragon Altar" can be said to be a special trial as well as a secret realm.
Many Spirit Masters and Spiritual Beasts who have returned alive from the "Candle Dragon Altar" have achieved tremendous increases in strength.
According to their descriptions, they traveled back to the past or arrived in the future via the River of Time, and under the influence of the mighty power of time, both they and their Spiritual Beasts significantly leveled up.
Moreover, they gained quite a few benefits during those segments of past or future time.
However, after a certain period, they would feel a sense of detachment and then return to the present time.
Of course, there are also many Spirit Masters and Spiritual Beasts who never returned; they might have gotten lost in the river of time, or perhaps they remained permanently in the past or future.
