Jing Yan finished patching up the first flaw of the Moon-Cutting Sword Methods in about four hours. The repair had cost him more than 100 Spiritual Stones.
Due to having upgraded his rank, Jing Yan's rate of absorbing Spiritual Stones had become a lot faster as well.
Jing Yan had spent around 200 Spiritual Stones in patching up over a dozen flaws in Moon-Freezing Triple Waves, yet it had taken more than 100 Spiritual Stones to patch a single flaw in the Moon-Cutting Sword Methods.
Just from that, he could tell that fixing all the flaws in the martial system would require massive sums of Spiritual Stones.
It was fortunate that Jing Yan had already prepared for that.
Jing Yan finished repairing the second flaw in the Moon-Cutting Sword Methods half a day later, which cost him more than 300 Spiritual Stones.
He then fixed the third flaw a day later, which came at a cost of more than 500 Spiritual Stones.
