William moved to Raccoon City in late 1979, into an apartment near the university, and construction is expected to be finished in early 1980. During this time, William finished training with the umbrella, and Albert provided William with research on the T-virus and its effects. William was appointed as the supervisor of the university lab and was entrusted with overseeing the researchers and interns who would be employed by Umbrella. William had no idea that Spencer was putting him through a test behind the scenes to see what he was capable of.
The T-virus's side effects fascinated William, and he wanted a sample to investigate which DNA components mutated and which didn't. However, he was advised to wait since he needed a risk-free environment in order to perform his research. So he went out and investigated Raccoon City, visiting the places that had been recommended to him and meeting some interesting people.
The institution's construction was finished rapidly. William was given an office directly adjacent to his own laboratory, and there he was given one sample of the T-virus. Through his viral study, William finds that junk DNA may convert part of the double helix, releasing latent components that can produce remarkable outcomes. Certain mutations in people infected with the virus can result in necrosis. After researching the T-virus, he concluded that in order to develop the human species, he must create his own virus. He also had to work and look after the entire laboratory.
After many weeks at the university, William is unsatisfied and furious with the researchers, who can only do menial jobs and moan about them to him. William had requested that Albert transmit him some of the T-virus study data, but obtaining permission to do so took some time. William was so fed up with everything that he decided to take a break and meet up with a buddy he met in the city named Robert Kendo. Robert Kendo was the son of a gun store owner, and William was captivated by Robert Kendo's inventive ideas for gun attachments.
William was surprised to be invited to their home for supper and quite liked his time there. When it was time for William to leave the house, Robert's mother handed him a sweet herb pie to take with him. William became interested in the herb after learning that it was made from green plants found only in the Arklay Mountains, that it had an effect on tiredness, and that it helped to increase the body's natural healing mechanisms so that wounds healed faster. Soon after, he began researching the herb's biology. Because the research data was given to William's lab while he was still working on his study, he needed to divide his time between the two.
At the beginning of 1981 After months of research, William developed two separate salutations, one with a small healing power and the other with a mid-healing power, by mixing the green herbs with a weak and strong chem fluid, respectively. The minor one was transformed into a first aid spray, health tablets, and simply a raw herbal tablet that treated small wounds, burns, and moderate pains in one minute. Both the spray and the pills were intended to be over-the-counter medications. The medium-strength one he designed was made into a medical injector that, when applied close to an open wound, caused the wound to heal in ten minutes as long as the individual stayed immobile. In addition, he developed a fast-acting recovery medicine that restored people's capacity to continue when they had hit their limit and were unable to continue for five minutes.
William presented his innovations in a meeting with several executives from Umbrella Pharmaceuticals and a lawyer. The topic at hand was the patenting of William's ideas. As payment for patenting the goods, he received a percentage of everything Umbrella sold. Spencer decided to reward him with some lesser-known facts as well as permission to conduct his own viral research at his lab. When he returned to his laboratory and had enough money to start creating his own virus, he put his research on additional herbs in the mountains on hold.
By late 1981, William had isolated a pathogen after working on transforming junk DNA into something useful and injecting it into the chimps, then infecting them with the T-virus, observing changes in the chips, extracting samples, disposing of the chimps, and then studying the changes. After several repetitions of this procedure, William found the proper stable pathogen, developed it into a (+)ssRNA virus, and named it DX-118 after the number of chimpanzees who died as a result of the virus. The results of injecting DX-118 into chimpanzees were unexpected: all of the subjects showed some form of good and beneficial development, such as increased cognition and strength, among a number of other symptoms. When the chimps were infected with the T-virus, their cells displayed chimeric behavior and mixed together. Furthermore, the infected chimp developed claw-shaped fingers similar to those observed in lickers, yet the chimp retained its ability to see.
William was initially happy with the results but quickly realized that the next step was to undertake large human trials; unfortunately, he lacked the resources to do so and would require substantially better resources to carry out this stage. William, like his ambitions, needed to make everything perfect in order to establish a new world. After some contemplation, he moved his focus to other plants that he might examine and deliver to Umbrella in return for what he needed.
