The weather is getting colder, and people are becoming weak and sluggish, except for those on duty and those engaged in daily task arrangements.
Everyone basically spends the daytime in the underground plantation base and returns to their rooms to sleep at night.
The three young wolf puppies, their condition has been improving lately, looking quite lively compared to when they were nearly at death's door.
One day, while Li Yu was in the duty room, he stepped out with a thermos in hand and couldn't help but pour some water on the wall. In less than a few seconds, the flowing water slowed, gradually congealing into ice.
"Ice!" Li Yu seemed to have thought of something.
If we sprinkle water on the walls and let it freeze, it could actually increase the walls' defensive capabilities, ice is slippery after all!
If someone were to come by, trying to sneak up under the solid and slick ice walls would undoubtedly be much more difficult.
