At least, when Jun Mohuang was trapped in Huangyu Space throughout the day, she carefully observed the groove under the silver stalactite.
She acutely noticed that 20 of the 24 spiritual weapons were refined by her.
Those were the 20 Spiritual Weapons she had sold at the trading center when she first arrived at the Academy Of A Thousand Illusions.
Coupled with what Di Lingtian said about the sharpness of the saber in the Silver Moon Spring, it should have absorbed the sharpness of these spiritual weapons.
In other words, the production of the Silver Moon Spring might be partly due to the sharpness of the weapon.
Because Jun Mohuang had the black flame, the spiritual weapon she refined was even sharper than the spiritual weapon refined by ordinary refiners.
At this point, she suddenly had a bold deduction. The Silver Moon Spring suddenly produced an additional half a drop this time possibly because of her 20 spiritual weapons.
