During treatment, Mom was sent into the virtual world.
When she woke up, she saw the virtual desktop and the explanatory text left by the doctor on it.
At the time, Mom was unaware that he had already learned the truth. After all, the unit had confidentiality regulations regarding these safety incidents, and during the treatment stage, relatives wouldn't be informed; they would use various explanations instead.
For example, business trips, new purification course training, emergency purification events, and so on.
To avoid worrying him, Mom also didn't actively contact him.
At the time, she thought she probably wouldn't make it.
The only chance was the soon-to-be-released Monster World, which had a special medical channel leading directly to Eclipse City.
So, while he was competing for the Monster World qualification, Mom was also trying to gain qualification through the virtual network provided by the Life Support Tank.
