I'm sorry to take a day off. Acute gastroenteritis, which starts to hurt in the morning and is uncomfortable until the evening. I ran several tests in the past half a day, and my thoughts couldn't be connected, and I was upset in writing. I won't update it today, but I'll update it early tomorrow if the situation is better.

"Military Science and Technology" is sick, take a day off is in the hand, please wait a while,
