21st Century Necromancer

Blood is an essential component of the human body, a red opaque liquid that circulates within the heart and blood vessels, and is an indispensable tissue of the human body. Adult blood makes up about one-thirteenth of body weight and is composed of plasma and blood cells. The main function of blood is to transport various nutritional components such as plasma proteins, lipoproteins, as well as inorganic salts, oxygen, hormones, enzymes, and antibodies contained in plasma to various parts of the body, providing what cells need, while collecting various metabolic products from cells and transporting them to their respective destinations. Physiological changes and pathological changes in a living organism can often cause changes in blood composition, so the detection of blood components has very important clinical significance in clinical medicine. Recently, Japanese medical science has developed a technology that can detect cancer with just a drop of blood and has transformed it into a product that can be introduced to the market, showcasing the importance of blood. When we administer medication intravenously in clinical treatments, the goal is to enable the drugs to reach the patient's entire body or the lesion more quickly to achieve the healing purpose. After all, whether it is oral or topical, the absorption of drugs by the human body ultimately needs to be transported to various parts through the blood. By the same token, if we wish to make some change to a person's bodily functions, affecting the blood is the most effective method. So when Kyuuzai Ryousen injected the Healing Potion, reformulated by Doctor Chen Yu, into Keiko's father's body, this potion infused with the power of the Dragon Bloodline began to work almost instantaneously within him. Because it was injected through the blood vessels, as soon as the Healing Potion entered the bloodstream, the first to be affected were the blood cells in his blood. Thanks to a very popular comic these past few years, most people have acquired some vague concept and understanding of blood cells, with red cells, white cells, and platelets comprising the blood cells within the blood. Red blood cells are responsible for transporting oxygen, platelets for clotting, and white blood cells as part of the immune system take on the role of destroying and removing old or abnormal cells and cellular debris, while also combating pathogens and foreign bodies. Therefore, when the Healing Potion entered the bloodstream, the first to collide with it were the white blood cells. However, the defense line of the white blood cells was almost instantaneously breached, and the orange-red Potion rapidly combined with the red blood cells, which carried it along with the flowing plasma to all parts of the body. Then it separated from the red blood cells along with the oxygen they were carrying, to be absorbed by other cells throughout the body. The Healing Potion itself contained rich nutrients and active components beneficial to cells, which were quickly absorbed by the cells. Similarly, the components of Dragon Blood contained within the Potion were also absorbed swiftly and began to affect the cells themselves. Human bodies are, of course, stronger than that of lab rats, and the potion injected into Keiko's father was not as potent as the one Chen Yu fed to the rats, but the dragon blood component it contained still caused the cells within Keiko's father's body to begin mutating. This mutation didn't mean that Keiko's father would grow scales, bone spurs, or some other inexplicable hyperplastic tissues like the rats. It simply meant that the cells would become more robust, their original functions would be enhanced, and the cells that had fallen dormant due to his vegetative state would be awakened. And this was precisely the purpose of Doctor Chen Yu using this healing potion on Keiko's father—to stimulate the cells in his body with the external power of dragon blood, reigniting their vitality and initiative, rather than remaining passively stressed like a plant. Of course, such stimulation also brought about some problems. For instance, all mutations are uncontrollable. Although the power of dragon blood would direct these mutations toward the original evolution of the giant dragon, the human body is made up of countless cells, tissues, and organs that, despite having a unified direction of evolution, still lack coordination with each other. This led to conflicts among these organs and tissues as they mutated. The human body is fragile, a fact that goes without saying. Bacteria and viruses mingle within our bodies, maintaining a delicate and fragile balance, much like our various organs. Some functions are redundant; others are emergency measures or obsolete products from our evolutionary history. All integrated to form our body, they maintain a balance as tenuous as a sandcastle on the beach, which can be toppled with a gentle push. And now, this balance as precarious as an egg on a tightrope faced a storm. If Chen Yu had used the same Dragon Blood Healing Potion that he fed the mice, it wouldn't be saving a life but rather taking one, because the disruption of balance would resemble a world-ending super hurricane. However, it was merely a slightly larger than usual storm common at the seaside during summer. The mutation of cells wasn't rapid. Although dragon blood is powerful, its strength was significantly limited once thoroughly diluted. The balance was broken, but it resulted only in structural damage rather than complete collapse. Moreover, all cells, tissues, and organs were evolving, and in the midst of constant conflict, they were also adapting to each other. In this process of adaptation, a new balance was gradually forming. Only, the construction of this balance seemed quite intense. "Doctor, what in the world is happening to my husband?" Keiko's mother asked the on-duty doctor, who was checking her husband's condition, her heart full of worry. She had been ready to sleep, just wanting to check on her husband before bed. But she found his body becoming scorchingly hot, and his skin turning red like a cooked lobster. His eyes were wide open with bloodshot vessels, and from his throat came a low moaning sound, as if he were enduring tremendous pain. Naturally, this startled Keiko's mother. She quickly pressed the call button beside the bed, summoning the on-duty nurse and doctor. "The patient has an unidentified fever. Start with physical cooling!" After examining Keiko's father, the on-duty doctor couldn't understand the situation. A patient who had been in a vegetative state for a year suddenly developed an unidentified fever all over his body, which he found very strange. But as a medical professional, he had his ethics. While instructing the nurse to start physical cooling for Keiko's father, he also asked Keiko's mother, "Did the patient show any signs before this? Did he suddenly develop this fever?" "I don't know, it's just that today during the day, Doctor Chen Yu had someone come and give him an injection," Keiko's mother recalled the injection that Chen Yu had arranged for her husband earlier that day and hurriedly informed the on-duty doctor about it.
