It took two whole days for Ji-woo to integrate the Spheres with the Nullifier completely. During that time, he had to endure the pain his body had to suffer from the amalgamation. Not to mention the blood that spewed from his mouth could amount to several liters of volume.
Ji-woo lost consciousness after going through the two full-day processes. When he woke up, his whole body ached. He tried to get up and found his chest hurt. After checking, there were purple bruises on it. Then, a little blood trickled down the corner of his mouth.
He finally got to his feet with difficulty. He was truly exhausted, and his breathing rhythm was still irregular. Even the weights that only weighed 400 kg in total made it difficult for him to move. Previously, his body didn't feel heavy because of it.
