Since he had no plans to enter the River Styx anytime soon, Lynn stopped dwelling on the matter. He turned and headed to his room to prepare for the work ahead.
He took out the "Soul Furnace" he had moved from the laboratory, placed it in the center of the room, then retrieved the golden Dragon Soul and a large number of pure soul fragments.
The Dragon Soul was already nearing its limit. The sooner he mastered this life-saving method, the more at ease he would be.
Over the following days, he devoted himself entirely to his research.
He first carefully studied all of Morpheus's notes on refining Primary Souls and Death-Substitute Souls, using [Analysis] to examine, verify, and deduce every word and sentence.
Morpheus's research was indeed profound, but his thinking was limited in many areas. Combining it with his own understanding, Lynn constructed a more optimized refinement plan in his mind.
Feeding the Dragon Soul required precise control. Too little would slow its growth, while too much would overwhelm and collapse the soul body.
Every day, Lynn fed it a fixed amount of soul fragments at set times. At the same time, he observed every churn, every expansion, and every contraction of the Dragon Soul with his mental power, recording its "fullness" and "absorption efficiency."
Five days later, the Dragon Soul finally reached its limit.
The golden soul mist had grown so dense that it was nearly liquid. The dragon-shaped phantom at its center now clearly displayed dragon wings, claws, and a savage head. Every movement carried a faint dragon's might.
At this point, he could begin refining the "Death-Substitute Soul."
According to the refinement method for a Death-Substitute Soul, he needed to fuse fragments of the refiner's soul into the Dragon Soul to complete the final contract
