Immortality Begins With Internal Breathing

Before advancing to the Force Transformation realm, martial artists relied on blood qi energy, which circulated through the blood vessels throughout the body to supply power. After advancing to the Force Transformation realm, they condensed the more powerful true strength energy. True strength was stronger than blood qi and differed in nature, unable to flow through blood vessels. It required the opening of meridians to circulate within them.

Demon puppets possessed no intelligence and would not actively open meridians.

Pfft.

Lin Zheyu sliced open the demon puppet from the neck downward, peeling apart its chest cavity. A dense stench assaulted his nose, causing even him to feel a wave of nausea. Thick purple-black viscous liquid poured out as he opened the torso, and the foul odor filled the entire room. He quickly held his breath to block it out.

"The five viscera have all corroded away. The abdomen is nothing but an empty cavity... Hm, well, it’s not completely corroded. The heart remains. It seems to have grown stronger and more robust."

Lin Zheyu cut out the heart and held it up with his blade for closer inspection. Since beginning martial cultivation, he had killed many people. Yet studying a corpse in such meticulous detail still caused him slight discomfort, even if it was only a ferocious beast. The discomfort was minor.

"The muscles, skin, tendons, and bones throughout the body have all undergone structural changes under the erosion of Baleful Yin force. The fur shows the greatest change. The inner layer is densely covered with purple-black patterns... Fascinating..."

Using crude methods, Lin Zheyu studied the structure of this artificially refined living corpse demon puppet, astonished. As he continued, he became more certain that the energy of a living corpse demon puppet was supplied through blood vessels spread throughout its body. The Baleful Yin force had fused into the blood and altered its nature. This hypothesis was supported by the fact that the blood vessels across the entire body had been reinforced and enlarged.

"I wonder what the bodily structures of demon martial artists, half-yaos, and true yao are like."

A strong curiosity rose within him regarding the structures of these three types of beings. Unfortunately, this world lacked the advanced technology of his previous life. Otherwise, he would have liked to slice the demon puppet into sections for study. After more than two hours of research, he finally left the room, still reluctant. Outside, Gu Ye stood with a jug of wine, drinking while admiring the moon.

"Senior Sister, what brings you here?" Lin Zheyu asked in surprise.

"I came to see how your research went. So, did you discover anything useful?" Gu Ye asked with a smile.
