With a roar,
The blue lines on the subject's skin suddenly turned black.
The muscles began to twist and swell uncontrollably, and finally...
"Bang!"
A cloud of blood mist exploded in the scene.
When the blood mist dissipated, only a pile of unrecognizable chunks of flesh remained on the experimental table.
"Cellular breakdown caused by rejection."
The doctor's voice was calm to the point of being cruel.
"The 'berserk factor' in the bloodline of the Oni race was activated, exceeding the tolerance limit of the test subjects."
Similar results occurred 203 times in 327 experiments, with a mortality rate of 61.9%.
He then pulled up another set of experimental footage.
"This is Bloodline Transplantation experiment of the Lunarian Tribe."
The subjects were also clones, injected with blood essence that had undergone four rounds of purification.
This time, the changes in the subjects were even more bizarre.
His skin gradually turned dark gold, and two fleshy growths began to appear on his back.
But just as the wings were about to take shape, the subject's entire body suddenly burst into black flames.
--Not the controllable flames of Ember, but an uncontrolled, destructive fire that burns everything.
Ten seconds later, only a pile of ashes remained on the test bench.
"The 'Divine Fire Backlash' of the Lunarian Tribe."
The doctor adjusted his glasses.
"The experiment had a success rate of 32.1% and a mortality rate of 67.9%. The only successful case was that the subject possessed a slight innate fire resistance."
Finally, there's Moria's experiment involving mixed Oni bloodlines.
This time the situation is more complicated.
The subjects not only exhibited characteristics of the Oni, but their bodies also began to grow larger.
But ultimately, the test subject died with rapid breathing.
" Moria's bloodline is the most gentle," the doctor concluded.
"But it's also more complicated!"
"All the test subjects developed serious mental problems after receiving the initial transplant."
It exhibits stronger aggression and self-destructive tendencies.
The three sets of graphic data on the screen plunged the laboratory into a brief silence.
Kaido stroked his chin. "It seems the risks of a direct transplant are greater than we imagined."
The flames behind Ember flickered slightly. "61.9%, 67.9%... Doctor,"
Which scenario are you referring to when you mentioned a 70% success rate?
That's the best-case scenario calculated by the theoretical model.
The professor brought up a complex formula interface.
"Assuming the subject possesses the physical strength of Kaido, and the transplant process is 'bloodline stable',"
Simultaneously, it is used in conjunction with the highest-level life support system...
The theoretical maximum success rate calculated this way is 70%.
Gracia paused,
"But the reality is that there are almost no subjects who can meet all three conditions. So the actual success rate we face... is probably less than 30%."
Roy frowned. "So your conclusion is that direct transplantation is not feasible?"
"At least not now. Without a strong physique and a powerful spirit, success is almost impossible."
"But perhaps diluting the bloodline would work."
"It's too unsafe."
Roy shook his head helplessly, and after thinking for a moment Roy, he realized a crucial question.
"Doctor, why did these problems occur in the experimental subjects after the blood injection?"
"The root cause lies in the 'hierarchical suppression' at the genetic level."
Dr. Gracia retrieved a complex set of genetic maps,
"Look, this is the gene sequence of a normal human."
"And this is Kaido's Oni gene sequence, and this is Lord Jin's Lunarian Tribe gene sequence."
On the screen, the comparison of the three sets of gene sequences is clear at a glance.
The gene chain of an average human is relatively "simple," consisting of a standard double helix structure.
However, the Oni's genetic chain exhibits a violent "multi-helix" form, as if countless forces are intertwined within it;
The gene chain of the Lunarian Tribe is even more unique, exhibiting a flame-like "fractal structure".
Each segment is self-replicating and self-optimizing.
"That's the problem."
The doctor pointed to the genome map,
"The genes of higher races possess a natural 'aggressiveness' and 'exclusivity'."
When these genes enter a normal person's body, they don't integrate obediently.
Instead, it will instinctively 'devour' and 'replace' the original gene sequence.
"If this process gets out of control, it can lead to the collapse of the host's genes—just like the experimental subjects you just saw."
Gracia pulled up a slow-motion video,
"Look at this. After the Oni gene was injected, everything was normal for the first thirty seconds."
But starting from the thirty-first second, the Oni's genes began to replicate on a large scale.
It forcibly replaces the host's original muscle and bone genes.
The host's body could not withstand this drastic change, and ultimately...
In the footage, the test subject's muscles swell up like air before bursting open with a "bang".
"What if the recipient themselves possesses a higher-level bloodline?"
Roy asked,
"For example, have Kaido accept the bloodline of the Lunarian Tribe, or have King accept the bloodline of the Oni?"
"It's theoretically feasible, but the risks remain significant."
The doctor pulled up another set of simulation data.
"We've done the calculations; even with a physique like Kaido's..."
Even if one directly receives the complete bloodline of the Lunarian Tribe, the probability of rejection is over 40%.
Because the two superior bloodlines 'compete for dominance,' a 'genetic battlefield' forms inside the body.
The flames behind Jin flickered slightly. "So the dilution method won't work either?"
"Dilution can only reduce short-term rejection reactions, but it cannot solve the fundamental problem."
The doctor shook his head.
"Diluted bloodlines do integrate more easily, but the effects are greatly reduced. And once the host begins to grow stronger..."
The diluted bloodline will gradually 'revive,' and rejection may still occur at that time.
The laboratory fell silent once again.
It seems that the path of Bloodline Transplantation is much more difficult than imagined.
But at that moment, a light suddenly flashed in Roy's eyes.
"Doctor, what if we try a different approach?"
He said slowly,
"Not transplanting from the outside, but 'cultivating' from within?"
"Internal training?" The doctor was taken aback.
"Right."
Roy pointed to the genetic map on the screen.
"Since high-level bloodlines are aggressive, why don't we create a 'container'?"
Let them grow and fuse naturally inside the container? And then extract the results from the container after fusion is complete?
The doctor seemed to be deep in thought, "You mean...?"
"Could we use cloning technology?"
"Clone?"
"That's right!" Roy's tone became excited.
"Could we use cloning technology to cultivate 'carriers' specifically for bloodline fusion?"
While this vessel is still an embryo, genes from the Oni, the Lunarian Tribe, and even more rare bloodlines are simultaneously implanted.
"Let these genes naturally fuse and adapt during the vector's growth process."
Roy spoke faster and faster,
"It's like extracting my bloodline and directly fusing it with three different bloodlines,"
"Of course, this process must be primarily based on 'my own' bloodline, and directly nurtured."
"Once the experimental subjects mature, we can extract their genes for transplantation. Wouldn't this reduce the risk of rejection?"
