Expelled
Little did Jason know that the 'fun' he had mentioned was anything but that.
Extinguishing the mana vein was not possible because the required heat was too high.
As such, he was forced to expel the mana vein which was more difficult than he could have expected.
On one hand, the clogged state of the Spiral veins had marginally improved when Solaris had cranked up the flame to a certain degree.
However, it was only afterward that the true challenge began which was directly noticeable as Jason inserted his mana, or to be precise a thread of mana into the Spiral Spirit egg.
Not only was this alone already dangerous because it could lead to a complex chain reaction that could be caused by the repulsive energies of spirit force within the Spirit, and his Mana.
Nevertheless, he did what he had to do in order to pull out the dead mana vein.
