Cactus flower language:
Cactus is the most delicate thing in the world, delicate as water, and it loses its life when touched. God can't bear to put a suit of armor on his heart, as hard as iron and with hurtful steel thorns.
From then on, no one can see the heart of cactus, and all the creatures near it will bleed profusely. After a long time, a brave man tried to eradicate this evil thing. The sword fell and the cactus became two halves, but the middle was green liquid.
It turned out to be a sealed cactus heart, because the loneliness that no one understood turned into a tear. So the flower language of cactus is-strong.
