As soon as Xu Shu returned to the inn, he began devouring the Erosion Crystals in his own bathroom.
Five white Erosion Crystals were not a large number; under normal circumstances, it would take a little over half an hour to finish them off cleanly.
But Xu Shu was just at the point of a breakthrough for a First-tier Warrior, so it also took quite a bit of time to ultimately complete the process.
The process was somewhat convoluted because each time there was an upgrade, the blood that sprayed out would be more abundant, and the pain of bodily erosion naturally became more intense than before.
That's why many people get stuck at a certain level, unable even with the supply of Erosion Crystals to level up.
This indescribable bottleneck exists as a challenge for every Transcendent.
Wanting to overcome it, mere willpower is not enough.
You must have ample talent and an epiphany in your state of mind in order to surpass yourself.
