Kang kangs is a technical craft, but luckily, right next to the school is a construction site, inhabited by multitalented foremen.
It's just the work of making a raised heated bed in a cellar, a task like which people here have never seen in their lifetime.
But it's not to say it can't be done; a meal of meat and alcohol gets it settled.
The real problem lies not with the bed, but with the air-raid shelter.
Truth be told, Wang Yunxiao and the others only occupy a few rooms at the entrance, used for storing canned luncheon meat and some miscellaneous items, and they have never ventured deeper.
Who knows how deep it extends; based on the experience of the last time they explored an air-raid shelter, it could possibly run for several kilometers.
What if something bizarre and peculiar emerges from inside and devours Eldest Miss Li?
Wang Yunxiao took his brothers for a round inside; they walked for a good two hours and still couldn't find the end.
