[Aiden's POV]
Waves of mana struck against the wall, which was thinned out with cracks all over the wall. As the continuous stream of mana collided with the wall, the cracks widened, and the wall finally broke.
An ethereal feeling washed all over my body as I opened the 6th node on the 28th day. This has been an uphill battle, as expected.
After I started cultivating and practiced my breathing technique for more than a day continuously, I only stopped after my whole body started aching. This was Cultivator's Fatigue, a common and ever-existing bane to all cultivators.
The more mana I pushed into my body and all the mana vessels and opened nodes worked overtime to complete the process of Mana → Mana vessels → Opened Nodes → Origin Heart → Closed Node.
This continuous process puts a strain on the whole body, Origin Heart included, which is commonly known as Cultivator's Fatigue.
