Only lily needs chlorine in plants, but he only needs to have enough chlorine pressure around him and not consume chlorine. All crops are like this, and they do not consume gas. Lily can be made into small pills to enhance immunity, but protection is not necessary. I have never planted lilies.
I haven't used the mine washer either ~ because there is no need at all ~ You can make a secret room full of chlorine, put a storage box or refrigerator in the secret room, and put something with a virus in it. If you don't consume chlorine, the virus will die in a short time.
Before the spacesuit appeared, I washed my hands with bleached stones. The bleached stone will volatilize into chlorine gas, soak the storage box in water, and then put the volatile things in the box, so it won't volatilize.
So the amount of chlorine on my map has never been reduced, so I still hope to have two natural gas springs and bring more natural gas generators ~
