Back in the Spirit Dimension, they had finally created the Negative Connectors. Now they had to wait for some time so that their soul could get used to the new addition. This also allowed them to rest a little and also recheck if they had made any mistakes, They then resumed and began working on the Arteries.
They first fused Soul, Lunar Shadow, and Stellar Fire attributed mana together with Faith and then began shaping the Arteries. The Arteries began from where their pineal glands would be and extended to all parts of their bodies. from an outsider's point of veiw, it looked absolutely breathtaking but to the boys, it was nothing but pain.
At this point, they had started screaming. They eventually stopped becausse it was taking too much of their already low energy. Once they were done with the Arteries, they realised a big problem that they had forgot about. Unlike a heart, that would keep pumping the mana, they had no pump for the Soul and Mana Conduits.
