Flaws in the Serum

Shen Fei watched as the man before him had his mouth sewn shut while the surrounding assistants continuously tested Experiment Body No. 1's self-healing ability against the Logan data Shen Fei had previously collected.

"President Shen, the skin's healing speed is only five hundred times that of an ordinary person..."

The Black man could only watch as a piece of his skin was cut away while the assistants recorded the rate at which the wound healed.

"The muscles are one thousand times faster than those of an ordinary person."

"The bones are two thousand times faster!"

Set after set of data was continuously tested. Listening to the results being called out, Logan began to doubt for the first time whether he could truly escape this devil's grasp.

What did it matter if he had self-healing ability? He was still being studied like a White Mouse.

Moreover, this man's goal was not to create weapons like Stryker. Weapons were meant to be used, so sooner or later, Logan would have been released. That was also why he had managed to escape back then.

This man's purpose was research. Research materials could never have freedom.

The Black man's joy at obtaining extraordinary abilities vanished instantly. He felt even more intense pain, because with self-healing ability, the assistants became even more ruthless, utterly unconcerned with his suffering.

Strange muffled whimpers came from Experiment Body No. 1's throat. The intense pain made him wish he could pass out, but the moment the people beside him noticed any sign of unconsciousness, they immediately injected him with stimulants.

All to obtain the most accurate data.

Listening to the assistants' reports and comparing them with Logan's data, Shen Fei soon frowned.

This definitely could not compare to Logan at his absolute peak, since the method he had used was Gene Infection to begin with.

But he discovered that although the test data was weaker than Logan's current condition,

it could still reach seventy percent of Logan's level, even eighty percent when it came to the depths of the bones.

"Test the same areas on Logan again."

Logan, who had been watching the experiment from the side, suddenly froze. Why was it his turn again?

He wanted to speak, but the assistants had already started.

"You devil!" Logan snarled with an incomparably twisted expression. "Professor X won't let you get away with this!"

"He's already dead... No, that's not right. He should have been reborn in his brother's body by now. But it will still take some time for him to return to his peak.

That amount of time is enough!"

Shen Fei spoke calmly, completely unafraid of Logan's threat. During this period, Logan could be considered the strongest Mutant, but even that was nothing special.

Figures like Professor X and Magneto had both been dealt with by the United States government.

One had died physically and resurrected in the body of his younger brother, who had already become a vegetable.

The other had been injected with a massive amount of X-Gene Inhibitor. His abilities had probably recovered by now, but at the moment, he was little more than a cripple. If Shen Fei had known where he was and if Magneto were not likely protected by many Mutants,

Shen Fei would have gone looking for trouble with Magneto himself.

Hearing how thoroughly Shen Fei understood the situation of the Mutants, Logan momentarily forgot even the pain of having bodily fluids extracted. "How do you know all this?"

But Shen Fei had already lost interest in talking. He kept calculating as he examined the data the assistants handed him.

"Adamantium..."

Shen Fei looked at the deepest parts of the bones. Because Logan's entire skeleton was made of Adamantium, they had no way to cut off bone samples for research. They could only use a Vibranium drill bit to extract a little marrow from inside his bones.

"So Adamantium isn't that perfect either." Shen Fei turned his gaze to Logan and asked, "Have you felt as though you're no longer as young as before? Even your healing ability has weakened?"

"That is everyone's fate. Not even Mutants are exempt."

"No. You cannot imagine the source of Mutant abilities. How could someone who possesses self-healing ability like yours grow old?"

Logan frowned and growled, "Then what do you think it is?"

"Of course, it's that indestructible Adamantium skeleton of yours!

This metal has fused with your Self-Healing Factor into a new form of active matter, a metal that can continuously grow.

Your defenses will grow ever stronger, and your physical discomfort will lessen, but your healing ability will weaken.

Because this special metal suppresses the growth of flesh and blood, while also releasing a rather unusual substance that damages your Self-Healing Factor."

"It was fine before, since not much time had passed.

But now you've noticed it, haven't you? As the years accumulated, your healing ability weakened, and you began to age.

When your Self-Healing Factor is completely destroyed, that will be the day you die!"

Shen Fei said. This indestructible metal skeleton was likely the reason Logan had entered his twilight years.

Logan froze. What Shen Fei said actually seemed to make some sense.

"But there are advantages and disadvantages. At the very least, it protected your brain.

You lost your memories before because your brain was damaged. Your brain cells may have recovered, but all your memories were gone.

Without that skeleton protecting it, someone as reckless as you would lose his memories all the time."

Shen Fei shook his head. He could try this method as well, but he would at least need to replicate Logan completely before considering it.

Besides, Shen Fei had plenty of backup plans for attaining defensive power on the level of Logan's skeleton. There was no need to sacrifice healing ability in exchange for defense.

Listening to Shen Fei, Logan became even more stunned. How did this man even know that he had lost his memories?

Meanwhile, Experiment Body No. 1, the Black man, was continuously having tissue separated and parts of his body cut away. His self-healing ability kept taking effect until Shen Fei suddenly said, "His muscle tissue is healing more slowly!"

"Yes, it has dropped by twenty times compared to an ordinary person."

In Shen Fei's view, the bicep from which a piece of flesh had been cut was beginning to heal more slowly.

Moreover, more and more sweat appeared on the Black man's face, his complexion gradually turned pale, and his eyes had become unfocused.

"Test his baseline indicators!"

Before long, Shen Fei looked over the increasingly weakened Black man's data.

His physical indicators were plummeting because the cells within his body were undergoing spontaneous apoptosis.

Cell apoptosis was controlled by the cell nucleus. It was often a special mechanism for eliminating mutated cells and could also cause certain organs to degenerate.

"Blood glucose, blood lipids, and blood pressure are all dropping rapidly. The sodium and potassium ions in his body are in disorder, and the cell membranes in various cells are rupturing..."

A succession of test results appeared before Shen Fei. "Should we stop?"

One assistant asked softly. This was their first successful experimental specimen. If they nursed him back to health, he could still be used for a very long time.

"Continue. I need to test its side effects and its limits!"

The other five experiment bodies and Logan could only watch as a living person finally seemed to melt into a puddle of rotten sludge.

The assistants hurriedly collected the sludge and incinerated it in a furnace.

Shen Fei looked at the final test data. "Test all five of them. Next, calculate how long one vial of Phoenix Solution can last, and how to let ordinary people gain self-healing ability without dying!"
