Adams looked up at that seemingly ordinary bottle of medication, which didn't look like the high-tech product it was rumored to be. It had no sci-fi feel, just a small bottle of ordinary liquid.

He didn't dare ask, but his mind was filled with countless question marks.

There was actually very little of the liquid, only fifty milliliters. Besides the K biological agent, it contained a specially formulated solution to keep it alive. Everyone gathered around just to watch his infusion, with no other special treatment.

A few minutes later, Yang Ping confirmed there were no issues and left a few doctors and nurses behind, taking the others back to research.

The current K therapy no longer required so many doctors to standby; such presence would be a waste of time since K therapy was now very safe, and the risk was almost the same as a regular infusion. Even if there were accidents, normal doctors and nurses could handle it.

Only fifty milliliters of liquid, it finished dripping quickly. The nurse removed the infusion tube, sealed the IV mark on his arm, and then quietly waited in the ward for observation.

"The treatment is complete! If you feel uncomfortable, let us know anytime," said the remaining doctor to Adams.

Was this the world-renowned K therapy? Is it over this quickly; does this thing even work? The treatment just now was just an ordinary infusion; this process didn't seem to match its reputation at all.

"Is that it?" Adams was completely unprepared. Initially, he thought this was just some prelude to K therapy.

Tormented for days, he was always on edge, relying on sleeping pills to sleep, frequently going to the bathroom since morning, and this was the K therapy? The whole process was surprisingly simple, even simpler than infusions he'd had in the United Kingdom.

"Do I need to stay lying down?" Adams asked.

The doctor immediately said, "You can get up and move around freely. If you feel unwell, just let us know. Just consider it like infusing a bottle of saline solution. No need to worry, according to our current data, this therapy has very mild side effects, and sometimes there are no side effects at all."

The nurse took his ear temperature again; the temperature was normal, no sign of fever.

Now a new torment began. Could this small, plain-looking liquid kill the tumor cells inside him? He found it hard to believe.

In the United Kingdom, he'd already tried various advanced treatment methods, such as the cutting-edge particle beam therapy worth tens of millions of pounds. That machine looked enormous and futuristic, making one feel a sense of fear and awe of technology when lying on it.

There were also all kinds of novel chemotherapy drugs, targeted therapy, and immunotherapy. He tried every possible method, all at the forefront of medicine.

Now, compared to those sophisticated machines and drugs, this small bottle of liquid seemed too ordinary. If the doctors and nurses hadn't just informed him it was the K biological agent, he wouldn't even have thought his treatment had begun.

"What are its ingredients, I mean that bottle of liquid?" Adams had already read Yang Ping's paper and knew what this was about, but that was theory, pure text. Now he was seeing the actual product and needed to communicate face-to-face with the team that developed it.

Dr. Li, who remained behind, said, "That is the K biological agent. It is a protein structure modified from an adenovirus. It's a protein structure with life characteristics similar to a virus. It is now being distributed throughout your body with your blood circulation. It will penetrate the capillary walls, enter the spaces between cells, and then search for tumor cells. It can gather around tumor cells, accurately identifying them, invade tumor cells, and ultimately hunt them down."

Can it be that miraculous? Just a bottle of liquid.

"I don't feel anything now; it's fighting tumor cells in my body. Right now, countless tiny battles are happening. Shouldn't I be feeling something intense?"

In movies, it's always like this. When people are injected with some sci-fi agent, they are usually uncomfortable, struggling, twisting, like their muscles and blood vessels are about to explode, indicating some huge energy conflict in the body.

But now, he felt nothing; even drinking a bottle of water would give some fullness. Now he felt nothing, not to mention any feeling of a large energy conflict.

Could it be that the drug doesn't work? Has it become ineffective in his body? Do others feel this way too? Adams was again filled with question marks, and thinking about these questions made him uneasy.

"Our K biological agent has undergone many improvements and is now very mild. During treatment, there won't be any strong reactions. You might not even feel anything. The first-generation biological agents weren't this mild. It was like a raging beast, hard to control, causing sustained high fevers, coma, or intense immune reactions. Some side effects were very severe, and subjects could be in life-threatening danger at any time," Dr. Li explained to him.

The first-generation biological agent seemed more forceful. Does the now mild biological agent still have any fighting power?

Adams began various internal tangles again. Did he miss out on the fierce first-generation therapy? And now, was the mild K therapy merely a compromise by researchers toward safety? Perhaps safety really improved, but it might no longer have the once magical effects.
