When Lin Feng entered the surgical floor, he saw Ling Yi and Ling Shuyan discussing how to proceed with the surgery for the last two Battle Group Leaders.
At Tier Two Late Stage Perfection, with Physique and Spiritual Attributes both above nine hundred, it was highly unlikely that implanting a Genetic Gland at this stage would result in successful Assimilation.
After all, the strength of their own immune systems was already nearly on par with the specialized cells released by the Genetic Gland.
The rejection reaction to the Genetic Gland would also be far more intense.
Hearing their discussion, Lin Feng’s brow furrowed slightly.
In reality, his concern was whether the Zerg genes, after the gland implantation, would activate the Spine Zergs’ Realm Trial for the two leaders.
After all, there was the precedent of Shen Jie, and Ling Yi had also said that after advancing to Tier Two Peak, Tiger Spine Zergs, Samurai Hunter Zergs, and Genetic Warriors all had a certain chance of initiating the Realm Trial as long as they possessed Spine Zerg genes... to receive a gift from the Spine King, or even the Spine God.
However, for purebred Tiger Spine Zergs, this required first returning to the Land of the End in the deepest part of the Underground to compensate for deficiencies in their Spiritual Attribute, and then proactively initiating the Inheritance Trial as a collective.
As for hybrid species like Samurai Hunter Zergs and Genetic Warriors, the latent Mental Realm within their genes would typically only be passively triggered when they experienced a death-defying battle and felt the threat of mortality, pulling their consciousness into the trial.
Shen Jie’s incident was a case in point.
And because Samurai Hunter Zergs and Genetic Warriors were new species created through Genetic Fusion, their success rate when facing a Realm Trial was practically zero.
Only a very small few could defeat the King Spine Zerg within the Mental Realm and master the inherited Mental Realm.
Most would die during the trial.
This was also a defensive mechanism established in advance by the Cosmic Race to protect its own genetic inheritance and prevent it from being stolen and exploited by other races.
Without mastering the Mental Realm, one could not step into Tier Four.
Therefore, Lin Feng was worried that if these two Tier Two Late Stage Perfection Battle Group Leaders encountered a dangerous situation during the surgery, they might accidentally trigger the Realm Trial.
Having just fused with Zerg Race genes, their mental state would be far worse than Shen Jie’s, and there weren’t any Tier Two Zerg Eggs nearby to be freely used like before.
Lin Feng and Ling Yi were even less confident they could rescue the two if they became deeply trapped again.
To ensure the experiment’s safety, Lin Feng called Ling Yi over and quietly asked her about this matter.
Regarding this point, Ling Yi gave a definitive answer:
"Don’t worry. Right after the surgery, their Fusion Level with the Zerg Race genes will still be very low, not high enough to meet the fusion threshold for triggering the Realm Inheritance."
"At most, the flesh around the Fusion Zygote might mutate under the influence of the Mental Realm, break free from the host’s brain’s control, and turn into a mass of wildly proliferating living flesh, just like cancer cells."
The corner of Lin Feng’s mouth twitched. ’The situation Ling Yi described sounds even more terrifying than triggering the Realm Trial.’
’But as long as the Realm Trial isn’t triggered here, then everything should be manageable.’
"Have you explained the situation to them?"
Lin Feng continued to ask.
Ling Yi nodded:
"The two leaders still insist on trying. After all, seeing their own squad members able to instantly erupt with Tier Two Middle Stage power after the modification... the temptation is just too great."
Lin Feng sighed softly:
"Alright, then you do your best..."
Ling Yi looked at Ling Shuyan, who was standing behind Lin Feng:
"A Tier Two Late Stage Perfection Awakener is already about as strong as I am. Remote Control isn’t possible; I have to use direct physical contact to control the Assimilation process."
"For the last two surgeries, Director Ling has decided to operate personally, to finish all the modification surgeries before tonight."
Lin Feng frowned:
"She won’t let you get involved? Don’t worry, I’ll have a word with her."
He then found Ling Shuyan and, offering his personal guarantee, arranged for Ling Yi to enter the operating room as well, to serve as an assistant to Ling Shuyan.
With Lin Feng’s assurance, Ling Shuyan, no longer needing to worry about the consequences, breathed a sigh of relief. After some thought, she agreed.
At that moment, the seventh batch of modification surgeries was successfully completed, one after another.
Ling Shuyan instructed a subordinate to notify one of the Tier Two Late Stage Perfection Battle Group Leaders to enter the operating room.
Then, she and Ling Yi changed into blue-green sterile sealed suits to face the final challenge.
Fortunately, with Ling Yi overseeing the entire process, both surgeries were completed without any major incidents.
However, suspicion grew in Ling Shuyan’s heart, and when she looked at Ling Yi again, her gaze was clearly different.
Because during the surgery, her reminders had been too timely and crucial—it was as if she were a human-shaped auto-scanner, monitoring the patient’s physical condition with perfect clarity.
Ling Shuyan suspected that Ling Yi’s Superpower was not Spiritual Control as she claimed at all; something like physical control would be a more fitting description.
’But doubts are just doubts. I can’t just directly question her privacy in front of everyone.’
After the surgeries were over, Lin Feng, bringing along a stunned and silent Liu Yueqi, found Ling Shuyan:
"Director Ling, I want to know how many of the test subjects from the previous batches are still alive."
Ling Shuyan’s eyes narrowed slightly as she looked at the young woman following behind Lin Feng. She could feel a distinct aura from her, like a sharp blade.
"There are still some left. A few of them have pretty good tolerance and Willpower. What? You want to show her the ropes?"
Lin Feng nodded, patting Liu Yueqi’s shoulder:
"My subordinate here might have a blood feud with them..."
"She needs to settle things personally."
