Three years after Core Formation, Chen Mobai successfully broke through to the second layer of the Golden Core with the Pure Yang Scroll.
Even when measured against the history of the Immortal Gate, this speed was among the very top.
However, given his Heavenly Fire Spiritual Root and Fire Spirit Body, coupled with the Rank-4 Spirit Vein of Giant Tree Ridge, it would be abnormal if he didn't make such rapid progress.
During these three years, even when he was not at Giant Tree Ridge, he would use Spirit Stones for cultivation. It was precisely this unwavering, dedicated practice that allowed him to break through in just three short years.
Following the breakthrough of the Pure Yang Scroll, his Golden Core Domain expanded twofold, now with 80 cubic units of space.
The primary reason for such an expanse was his position as Sect Leader of the Divine Wood Sect, which allowed him to prioritize the use of Void Stones mined from Lonely Spirit Ridge for his own use.
