The battle paused briefly, giving Tang Li time to modify the memories of those temporarily incapacitated.
Before long, in the biological research institute, everyone who had not installed an intrusive brain-computer interface was immediately executed, their bodies collected into her spatial dimension and converted into spatial energy.
As for those who had installed intrusive brain-computer interfaces, whether they were members of the Holy Light Organization's R-nation branch or Z-nation citizens controlled by the Holy Light Organization, all of them had their memories altered.
During this process, Tang Li also traversed and surveyed the entire biological research institute.
The building where Tanaka and Watanabe were located, primarily focused on manufacturing the longevity potion, researching body enhancement agents, and cultivating long-lived organisms, was relatively normal.
Although live humans were used as subjects for experiments with body enhancement agents, it wasn't considered overly perverse.
However, within this biological research institute, many research areas were disturbingly abnormal.
This was particularly true for the buildings dedicated to the research of intrusive brain-computer interfaces.
Installing intrusive brain-computer interfaces, and tampering with or implanting false memories, could still be considered within a certain range of normality.
Erasing a person's entire memory, fabricating a life for them, and transforming one person into another were also not the most depraved acts.
The most perverse were the experiments concerning biological robots.
Here, Tang Li saw many individuals whose brains had been removed and replaced with electronic devices.
These people's heads did not have the ports for intrusive brain-computer interfaces, appearing similar to normal individuals.
However, their skulls had long been opened.
The control of their bodies was no longer by their original brains but by electronic devices installed within their heads.
Tang Li was unsure if these individuals could still be considered alive.
Or, one could say, their bodies were alive, but their brains were dead.
Here, Tang Li even found Xu Xinyue.
Although she had only been brought there for a few hours, her skull had been cut along the hairline, her brain removed and placed aside, not yet taken away.
It seemed they were preparing to install electronic equipment.
With the cerebellum, brainstem, and other tissues still intact, coupled with the maintenance provided by the institute's medications and the control exerted by computers, her body was still breathing normally, as if she were asleep.
A researcher whose memory Tang Li had modified demonstrated how to control Xu Xinyue's body to perform various movements using a computer.
Despite surviving in the apocalypse for three years and witnessing many scenes of cannibalism, Tang Li still felt a sense of nausea seeing this.
Even though Xu Xinyue no longer had a brain, Tang Li still granted her a quick end.
She instructed the researchers to place her brain back, close and repair her skull, leaving her body intact.
Fueled by the incident with Xu Xinyue, Tang Li later found herself less affected by experiments that involved extracting and digitizing various skills and knowledge from brains before inputting them into human minds.
While the extraction process was incredibly cruel to the original individuals possessing these skills and knowledge, it was highly beneficial to others who had installed intrusive brain-computer interfaces.
There was no longer a need for the learning process; acquiring any desired knowledge or skill was as simple as downloading it directly into the brain via the intrusive brain-computer interface, making it incredibly convenient.
However, to be frank, these achievements could have been realized without such cruel experimentation.
The data brain that Song Pinxuan was developing, when combined with a non-intrusive brain-computer interface, could achieve similar functionalities.
The only difference was that the learning process was still required, though it no longer involved rote memorization. One only needed to use their brain to store what needed to be memorized in the data brain.
This was a technology that Song Pinxuan had already achieved in his previous life, within the next 30 years, and could be replicated quickly.
After a period of busy work, Tang Li had gained control over everyone in the entire biological research institute who had installed an intrusive brain-computer interface.
The entire biological research institute, including security personnel, cleaning staff, controlled Z-nation researchers, R-nation researchers who had installed intrusive brain-computer interfaces, and Z-nation individuals captured for experimentation who were still alive, totaled over 5,000 people.
Tang Li was also quite angered by these R-nation people.
She had not expected that the history of R-nation people using Z-nation citizens for human experimentation would repeat itself on Z-nation soil during the apocalypse.
To prevent these crimes from being covered up after the great earthquake, Tang Li took out her phone and recorded all these atrocities.
After completing these tasks, news arrived from the Mercenary Guild and the F-city base that the encirclement of D-city had been completed and it was time to close the net.
