She digged trough the snow to see what made her fall. In the ice she saw a black liquid, because she didn't know what this is she cut that part off.
She ran back to the big tent that was a lab. She put the block of ice with the mysterios liquid on a table and melted the ice around the liquid. She turned around to search for her microscope. As she turned around a small part of the liquid dropped on the floor
Mei finally found the microscope and studied the liquid. The part that dropped on the floor suddenly started moving. „Interesting." Mei said as she found some living cells that got bigger and smaller. The liquid on the floor reached Mai and crawled up her foot

Tracer greeted Mei. „Yeah, it's nice to get out of the lab" Mei said.
„ Omg, what happened to your ass?" Tracer said shocked. „Oh, an experiment gone wrong and now i have this for a few days". They went to Tracers house to have some tea. „So? Anything new" Tracer asked. „Not reall, but Greenland is beautiful.
Mei asked Tracer if she could stay here and tracer agreed. At 1am Tracer went to sleep. Mei got the rest of the black liquid and put it into a syringe. She injected the liquid into Tracers ass. Tracer woke up and her eyes instantly turned pink. Tracer stood up. „ The next targets are Mercy and " Mei said in a deep voice. Because Mei injected the liquid into her body.
