Why is their first soul ring a thousand year soul ring and mine a hundred year soul ring?
In the Douluo Continent game, the duration of soul rings varied. Some soul rings only lasted for a short time while some soul rings could last for a thousand years or longer. This difference was determined by the spirit beast's rank and the spirit master's strength. Thousand year spirit rings are usually made from high level spirit beasts and their spirit power is extremely powerful, providing the Spirit Master with formidable strength and ability bonuses. And hundred year spirit rings are usually made from low level spirit beasts. Their spirit power is relatively weak but can also provide a certain amount of protection and enhancement for the Spirit Master. A Spirit Master's strength would also affect the duration of a Spirit Ring. The stronger the Spirit Master, the longer the Spirit Ring could be obtained and the duration of the Spirit Ring would also increase correspondingly. In addition, the spirit rings obtained by Spirit Masters in Spirit Master Grand Competitions and other competitions would also have different duration and effects. Therefore, the duration of the Soul Rings in the Douluo Continent game was determined by the rank of the Soul Beast in the Soul Ring, the strength of the Soul Master, as well as the way the Soul Master obtained the Soul Ring in the competition.
