Starting with the Progenitor Virus, he would gradually replace the uncontrollable viruses within her body, eliminating the defects caused by viral fusion.
This was Asa plan. As early as a month ago, Asa discovered that his constitution acted like a filter or a modifier; the fused T-Virus no longer belonged to the category of biological weapons.
Of course, not everyone could fuse with the T-Virus smoothly and without obstacles; Asa discovered this situation later while conducting research in NEST 1.
More often than not, after the modified T-Virus was extracted and isolated from the body for a period of time, it would "deactivate" after a while, and when injected into a test subject, there would be absolutely no signs of fusion.
This process would not change based on Asa will.
As for why Jill Valentine could fuse perfectly, it was very likely related to her constitution. After all, she was a perfect test subject who could even adapt to the Uroboros virus.
It was not strange that she could fuse with the modified T-Virus.
T-Evolution was born from this. Otherwise, wouldn't it just be a matter of diluting Asa own blood and injecting it? Why would it be so troublesome?
At this moment, the several types of viruses Asa injected into Lisa were not much different in principle from the creation of T-Evolution.
He used the more stable virus version within himself to replace the unstable version in Lisa's body.
Ten minutes after the injection, Lisa's massive body suddenly began to convulse.
From her deformed back, several tentacles burst out, writhing wildly on Lisa's body as if leeches encountering high concentrations of salt, while translucent red blood constantly flowed from the tentacles.
Soon, the tentacles were completely decomposed into blood.
Asa stood to the side, using instruments from time to time to check Lisa's physical condition as the two viral factions attacked and fused within her body.
Overall, Lisa's body was improving. The modified Progenitor Virus possessed powerful fusion and adaptive capabilities; whether it was the original T-Virus or the original G-Virus, the modified Progenitor Virus could absorb their superior genetic fragments and fuse with them.
"So that's it. The modified Progenitor Virus can provide the host with powerful immunity and viral phagocytosis capabilities. After injection, one is completely unafraid of the T-Virus's infection capability."
Asa recorded this down. The regenerative capability of the modified Progenitor Virus might be far less powerful than the modified T-Virus, but its focus was on providing physical fitness and immunity.
The experiment continued. Asa watched Lisa's physical changes with a cold eye. With the modified Progenitor Virus and two other mild viruses modifying her body, Lisa's body was changing at an extremely rapid speed.
"Restoring to original state" was not an accurate description. Asa thought of an adjective: eclosion.
Lisa's originally massive body of flesh and blood was constantly expanding. While the skin and muscles expanded, they were also festering and falling off at an extremely fast speed, with yellow fluid dripping all over the floor.
Within the gradually rotting body, new life was being born.
Using the location of Lisa's original brain as a reference, after the rotten face liquefied and flowed away, a young girl with flaxen-colored hair was revealed.
This face was so familiar.
Asa was stunned and pulled up the photo of the Trevor family from the computer.
It was exactly the same as in the photo: flaxen hair, a youthful face—it was exactly Lisa Trevor at 14 years old.
Lisa was born in 1954 and her real age was 44. She had been imprisoned and tortured by the Umbrella Corporation since she was 14, and now she had been restored to the appearance of a 14-year-old.
Was this reasonable?
As the flesh all over Lisa's body fell off like old flakes of paint, Asa found a white lab coat and draped it over Lisa.
The virus version within Lisa had been completely replaced by the virus modified by Asa. Side effects like low intelligence and physical deformity were all resolved. In other words, the current Lisa was a perfect viral adaptive subject comparable to Asa.
With the superposition of powerful viruses like the G-Virus, T-Virus, and Progenitor Virus, Asa could not imagine what kind of power this harmless-looking little girl would erupt with.
It really did fit the resident evil worldview—the lower the age, the stronger the power?
However...
Asa watched the real-time brainwave monitoring on the computer. The active brainwaves indicated that Lisa's brain had already begun to function, but she still hadn't woken up.
If he saved Lisa's body but she had no consciousness at all, wouldn't Asa have been busy for nothing?
Fortunately, upon inspection, Asa found the problem preventing Lisa from waking up.
Ever since the Progenitor Virus devoured and captured the NE-alpha Parasite, and Lisa relied on the parasite to recover a certain level of intelligence, this body had depended on the parasite as a second brain to store consciousness and regulate the body.
The parasite had become a part of Lisa's body, just like humans living in the 2077 World who needed brain-computer interfaces to maintain life and activity.
If one lost the brain-computer interface, they wouldn't die, but they would be unable to move an inch in the cyber world.
This was fine too.
Asa took out a parasite he had domesticated, turned Lisa over on the operating table, and injected the parasite into Lisa's spine.
After turning her back over, in just a moment, the girl lying on the operating table suddenly opened her eyes.
Those were violet eyes, exactly the same as Lisa Trevor in the photo.
When the owner of these eyes first woke up, her expression still carried a hangover-like confusion, staring directly at the light above the operating table, as if asking, "Who am I? Where am I?"
Very quickly, Lisa seemed to realize something; she tilted her head slightly, looked at Asa, who was thinking about an opening line, and a look of confusion appeared on her face.
"Who are you? Where are Mom and Dad?"
Asa scratched his head. How should he answer her?
Should he say, "Your mom and dad died over twenty years ago. One is just bones left, and the other has some skin hanging on the bones—do you want me to take you to see them?"
"Also, you are already forty-four years old. You aren't a cute girl; you're a middle-aged auntie!"
Wasn't that too cruel?
Asa guessed that judging by Lisa's appearance, she seemed to have lost all memories from after being imprisoned.
This was for the best. For a girl with an immature mind, thirty years of imprisonment and the experience of her parents' tragic deaths—forgetting was the best way.
In the end, Asa told the child a kind lie.
"Lisa, your mom and dad died in a car accident and have already been cremated. I am your distant cousin. You even held me when you were little—bah, I held you when you were little. Now, I am your guardian."
Asa had no choice. Lisa was 14, not 4. For a girl whose mind was nearly mature, a lie like "Mom and Dad went on a trip" would be easily debunked.
However, after hearing that her parents had died, Lisa's expression remained calm; she showed some sadness, but not much.
"What should I call you?"
"Asa. You can just call me Brother."
"Hmm, Asa."
This child. Lisa sat up, wearing the clothes Asa had taken out from his storage space, scanned the surroundings, and said:
"It's so disgusting here, Asa. When are we leaving?"
Although she said it was disgusting, Lisa remained expressionless; her exquisite face didn't even have a furrowed brow, huddled in Asa oversized clothes like a porcelain doll.
"Right away. Let me just do one last check on you."
