21st Century Necromancer
Chapter 814 - 810: Surgery

The division behavior of the four tumor cell samples did not come as a surprise to Chen Yu.

The reference group, which had no added substances, naturally demonstrated uncontrolled division and expansion, forming a large mass. In the absence of contact inhibition, tumor cells divide chaotically and without restraint.

The two samples with drugs added also did not exhibit any unexpected phenomena.

The sample with the broad-spectrum anti-cancer drug had all tumor cells' vital activities slowed to the point of near stasis. Cell division had completely ceased, and it could be said that these tumor cells were merely sustaining their most basic life functions, akin to entering a state of hibernation.

In contrast, the sample treated with the new drug displayed a vastly different situation. Although tumor cell division was similarly inhibited, cell vitality remained unaffected, continuing life activities just like normal cells, with only cell division impacted.

As for the final sample, which had both drugs applied simultaneously, Chen Yu looked at the tumor cells under observation and revealed a delighted yet intrigued expression.

After thinking it over, Chen Yu decided to call Inomata Naoki over.

"What's up, Brother Yu? Is there something you need?" Inomata Naoki asked as he approached Chen Yu.

Chen Yu didn't say much but gestured towards the microscope on the desk. "Take a look at this; it's quite fascinating."

"Fascinating?" Inomata Naoki seemed puzzled but after glancing at the four petri dishes on the experiment table, he quickly understood what Chen Yu was studying.

Without asking further questions, he adjusted his gaze to the microscope lenses. However, one look left him astonished.

Tumor cells, under a microscope, are drastically different from normal cells, and Inomata Naoki certainly wouldn't mistake them.

Yet, upon recognizing the contents as tumor cell samples, their appearance startled him.

"Brother Yu, how long have you cultured these?" Staring at the surprising tumor cell samples, Inomata Naoki asked Chen Yu.

"Three days." Chen Yu's lips curled into a slight smile as he mentioned a timeframe that surprised Inomata Naoki even more. "Amazing, isn't it?"

"Transforming tumor cells into this kind of state in only three days—could this result truly come from combining the two drugs?" Inomata Naoki exclaimed while repositioning his eyes to the microscope's eyepiece, marveling at the sight of the tumor cells visible in his field.

Their shared astonishment was justified. Under the microscope, the tumor cells exhibited a "withered" appearance, akin to a plant deprived of water for a prolonged period.

Cell dehydration is common biological knowledge, yet observing such a phenomenon in a nutrient-rich, growth-promoting medium—with tumor cells appearing desiccated as if sun-dried—was undeniably remarkable.

"It's currently unclear whether this is the result of the two drugs acting synergistically or the effect of new substances formed from their reactions." Watching Inomata Naoki's excitement, Chen Yu chuckled lightly and told him: "I'm leaving this sample to you. The experiment records are nearby—quickly figure out what's happening. I have a surgery to attend shortly, so I'll be off for now."

"No problem—I'll handle it," replied Inomata Naoki. His eyes never left the microscope, indicating that he had already entered a state of intense focus.

Although he once retreated to his hometown to raise horses, now that Inomata Naoki was back in this familiar environment, his long-dormant passion for medical research reignited once more, something even he hadn't realized.

Watching Inomata Naoki deeply engrossed, Chen Yu simply smiled before turning to leave the lab. With a diligent assistant who needed no urging, what was there to complain about?

As for why Chen Yu wasn't handling these matters personally—as he said, he had a surgery to perform.

The procedure was for the real estate salesperson whose cancer cells had already spread. While the tumor cells throughout his body were suppressed by the broad-spectrum anti-cancer drug, and his physical condition gradually improved with the use of healing potion, leaving the tumors untouched wasn't ideal. Hence, Chen Yu planned to surgically remove the tumor in his stomach.

For the remaining tumor cells elsewhere in his body, post-suppression via medication, the development of the new drug was awaited, and treatment would follow subsequently.

At the sink in the operating room, Chen Yu was washing his hands. For someone like him, this kind of surgery was practically effortless—there was no difficulty at all. It could even serve as an opportunity for hands-on teaching.

Such scenarios were common practice in the hospital; trainee doctors or interns often relied on these occasions to either observe procedures on the operating table or gain firsthand experience through actual operation.

"Professor, why operate on this patient? According to the treatment plan you previously outlined, wasn't the aim to use drugs to eliminate the tumor cells in his body for recovery?" One of the doctors participating in today's surgery asked Chen Yu.

"The patient's tumor cells have already spread, and while other tumor sites in his body indeed require medication to kill the cells and treat him, his stomach is the primary tumor site." Chen Yu glanced at the questioning doctor, continuing to explain as he focused on scrubbing his hands. "The progression of the tumor has resulted in his stomach losing most of its original function. Healthy cells in the stomach have been largely replaced by tumor cells. If we kill the tumor cells, his stomach would necrotize. Thus, tumor removal surgery becomes necessary."

After finishing his sentence, Chen Yu had already cleaned his hands and reached for a towel to dry off the water. He reminded the doctor still washing his hands, "Hurry up—the surgery is about to begin."

"Ah! Yes, Professor!" Startled by Chen Yu's prompt, the doctor quickly finished washing his hands, dried them off, and—with the assistance of a nurse—donned a surgical gown and gloves before following Chen Yu into the operating room.

Standing at the operating table, Chen Yu glanced at the assembled medical staff and began addressing them: "Today's surgery is quite rare. Normally, late-stage cancer patients wouldn't undergo surgical procedures. Having this opportunity to perform a tumor removal surgery for a terminal cancer patient is invaluable. I hope everyone seizes this chance to learn as much as possible. Now, let's officially begin! Scalpel."
