Marvel: Starting with Iron Man in the Apocalypse

Deep within the armory, a relatively independent and well-sealed compartment, originally used to store precision instruments, had been cleared out. This became the core area of ​​the temporary joint laboratory. Portable analytical equipment from Stark Industries and specialized instruments salvaged from Delta Force were interspersed, creating a peculiar research space that blended the technological styles of two worlds. The air was filled with the smells of disinfectant, ozone, and the faint odors of electronic devices.

Chen Haotian connected the silver, encrypted solid-state drive to a modified, powerful tablet computer that Tony had brought. Jarvis's subroutine began efficiently cracking the encryption protocol while backing up and initially organizing the data stream. Dr. Wesker and his team members busily and carefully placed the few precious samples they had brought with them—several sealed test tubes containing samples of T-viruses at different mutation stages and several prototype inhibitors they had previously attempted to synthesize—into a makeshift cryogenic freezer.

Tony didn't get involved in the actual processing of virus samples; that wasn't his area of ​​expertise. His interest lay more in the lab's "infrastructure." He was directing several strong researchers to perform a second modification on an old but structurally sound diesel generator that they had salvaged from a corner of the armory. The small piece of void energy crystal left over from the water purification process had been cleverly embedded into the generator's core circuitry.

"Energy output is stable...efficiency has increased by forty-seven percent...unbelievable..." Tony stared at the data Jarvis was providing in real time on the tablet screen, his eyes gleaming with excitement. "This thing is practically a universal catalyst! If it could be applied to my Arc Reactor..."

"Tony, focus on the present." Chen Haotian's voice interrupted his reverie. Chen Haotian had already browsed through the key files marked by Jarvis on the hard drive, gaining a deeper understanding of the T-virus. "According to Delta's data, the T-virus's RNA sequence exhibits a... deliberate and malicious design. Its mutations are not entirely random, but are 'guided' at several key nodes."

Dr. Wesker approached, his face weary, but his eyes still gleaming with the fire of a true researcher. "Mr. Chen is right. We suspected long ago that what Umbrella Corporation provided us might not have been some 'ancient virus' at all, but rather a simplified version or...test version of one of their 'final products.' The real source virus is likely far more complex and dangerous than we imagined."

"A test version?" Tony raised an eyebrow, putting down his tools. "Using the entire world as a testing ground? That's quite a feat." His tone was full of sarcasm, but also carried a hint of... "appreciation" as if he had encountered a "fellow traveler." If he were to evaluate it, this kind of world-destroying "project" would indeed fit the aesthetic of certain mad geniuses.

"It's not just a testing ground." Chen Haotian pointed to a complex three-dimensional molecular structure diagram displayed on the tablet screen, which was the core protein shell of the T virus. "This structure is extremely stable, but at the same time, it leaves a large number of 'interfaces,' as if... it is specifically designed to accept foreign gene fragments or energy imprints. Its mutability may very well stem from these 'interfaces' being 'filled' by the genes of different hosts or unknown factors in the environment."

This discovery startled Dr. Wesker. He leaned closer to the screen, his expression growing increasingly grave: "We've only focused on its transmissibility and destructiveness, never considered it from this angle... If this is true, then the Umbrella Corporation's purpose is probably not just to create biological weapons! They might be conducting some kind of... cross-species genetic engineering, or something even more terrifying..."

"Creating a god? Or creating some kind of controlled 'evolution'?" Chen Haotian interjected, his tone calm yet his words chilling. He combined his vague memories of the Resident Evil series with his understanding of various superpowered events in the Marvel universe to propose this hypothesis.

The laboratory fell silent instantly, save for the faint hum of the instruments. Several researchers who were observing the proceedings looked on in horror.

"Madman..." a young researcher muttered under his breath.

"But... from a technical point of view, it's not entirely impossible." Another researcher wearing thick glasses pushed up his glasses and muttered to himself, lost in academic thought.

Tony whistled, "Wow, that sounds way more exciting than my Arc Reactor project. So, we're now in a virus testing ground set up by a crazy company, possibly designed to create new species?" Far from being afraid, he seemed even more excited.

"It seems so at the moment," Chen Haotian confirmed. "Therefore, our research cannot be limited to how to eliminate it, but must also understand the underlying mechanisms, especially the source of that 'abnormal mutation.' This may help us understand the differences in life forms and energy processes under different world rules."

With the research direction clarified, the joint laboratory began operating efficiently. Wesker's team was responsible for using their expertise and preserved samples to conduct traditional virological analysis, focusing on monitoring viral mutations after exposure to different stimuli (including the weak energy field generated by Tony using the Void Energy Crystal).

Tony provided technical support; his modified generator not only provided the lab with stable and enhanced power, but he also used materials found in the armory to create several simple yet efficient air filtration and negative pressure systems, ensuring the biosafety level inside the lab. Simultaneously, he began designing a detector capable of capturing and analyzing subtle changes in the virus within an energy field.

Chen Haotian acted as the central coordinator, rapidly absorbing knowledge from both worlds using his academic prowess and high IQ. He was not only the project manager but also a high-speed learner and integrator. He could understand the obscure virology terminology used by Wesker's team, keep up with Tony's imaginative technological ideas, and often offer key insights connecting the two fields.

"Doctor, expose the third set of samples to 5% of the crystal energy field intensity for 30 seconds." "Tony, the detector's sensitivity needs to be increased by another order of magnitude. The virus's structural changes under energy excitation are far exceeding expectations." "Data shows that the 'interface' of the viral protein shell exhibited a brief 'resonance' phenomenon upon contact with void energy, but it was quickly overshadowed by more violent and destructive mutations… This seems like an incompatible energy conflict?"

Under his guidance, the research progressed rapidly. Within days, they achieved a series of breakthroughs. They confirmed that the abnormal mutation of the T-virus is indeed closely related to the external energy environment, especially when exposed to energy outside this world (such as void energy). In such cases, the mutation rate and direction deviate significantly from their original trajectory, becoming more unpredictable, but also revealing a stronger plasticity in its underlying structure.

However, as the research deepened, a vague unease began to grow in Chen Haotian's heart. The "sensitivity" and "rejection mutation" of the T virus to foreign energy reminded him of the operation of his own traversing runes. Runes, in essence, also mobilize and shuttle between the energy rules of different worlds.

The dormant rune within him seemed to have become more "active" under the intense research environment these past few days, occasionally emitting a barely perceptible pulsation, as if it had created a subtle resonance with the complex field permeating the laboratory, which was a mixture of T-virus factors and void energy.

This feeling was extremely subtle and fleeting. Chen Haotian attributed it to an illusion caused by his focused research and did not delve into it further. His primary task at present was to quickly uncover more secrets of the T-virus, accumulating more leverage for his upcoming return and other potential global crises.

The lights in the joint laboratory often stayed on all night, and the people inside worked tirelessly, as if trying to ignite the last spark of science in this post-apocalyptic world into its most dazzling brilliance. Amidst this busy activity, the shadows of the "Umbrella Corporation," which caused the apocalypse, and the potentially larger conspiracy hidden behind the T-virus, were quietly sown in everyone's hearts.
