They were the weakest of all Aurous Core cultivators. In fact, some of the Chosen Zifu Disciples were even more powerful than these Aurous Core cultivators.
For example, the Zhou Clan Patriarch, Zhou Minghao, was probably at this level.
The Golden Core cultivator's strength improved further. Naturally, after passing the Golden Core Lightning Tribulation, his mana was refined and his Great Dao realm was stable.
Generally speaking, Golden Core cultivators could reach the upper stage of the third-level Star Transformation Realm after transcending the Golden Core Lightning Tribulation.
Other than the special state of having just passed the Golden Core Lightning Tribulation, this level of Golden Core cultivator was the strength of the lowest Golden Core cultivator under normal circumstances, which was the strength of an ordinary early-stage Golden Core cultivator.
