Leave of Absence Note

The weather outside the city on August 12th is unknown.

The doctor and I have been hiding in the morgue for half a month, living in constant fear every day.

During that time, we went to the upper level of the hospital and stole some food and water.

The morgue is on the first basement level, but after exploring with the doctor, we discovered that the hospital also has a second basement level.

There is a coded door leading to the second basement level; only the dean should know the password.

The good news is that the doctor applied some medicine that made the hospital director's fingerprints appear on the keypad door, confirming that the password was four digits: 4, 6, 8, and 9.

For the past two weeks, the doctor and I have been trying to figure out the password. When the hospital director came, we hid in the morgue.

The hospital director also came to the morgue. Judging from the sounds, it seemed like they were putting the body on a trolley and pushing it to some unknown place.

Is it the second basement level?

Finally, the two of us figured out the password.

The second basement level is a laboratory, containing three rows of nutrient solution tanks. The tanks contain human corpses, animal corpses, and some indistinguishable wriggling chunks of flesh.

The doctor said it's very likely that doctors are conducting zombie virus experiments here, but that's not enough; there should be experimental reports.

The doctor and I split up; the doctor looked for the lab reports on the computer, and I looked through the cardboard box.

Inside the cardboard box was a very strange report. The cover had my picture on it, and the report was titled "Experiment Report on Zombie Virus No. 78." The test subject was... me?!

Experimental results: The experimental subject exhibited vital signs and was infectious; however, they have since disappeared.

I showed the doctor the lab report, and he remained silent for a long time. Finally, we both decided to escape from the hospital tonight.

Time is of the essence for escaping the hospital; I need to take a day off.
