"Planting?" Si Yan paused, blanking out for a moment.
Then she asked, "Gecko, I'm not stupid. In addition to soil, a plant needs water and sunlight to grow! There's no ultraviolet radiation, no sunlight in my space!"
The gecko crawled out of the space and patted Si Yan on the head.
"You can just get soil and water from outside. Didn't I just have you mess with mud? As for the sun, don't you have a lamp that simulates sunlight lying around in your space?"
Indeed, she had a lamp that charged with solar power and then simulated sunlight.
The thing wasn't for fighting and wasn't of much use, but Si Yan was of the wood element and carried it to observe plants.
Si Yan was taken aback. "There's no electricity."
"It charges with solar energy," the gecko rolled its eyes at her.
Si Yan: "..."
Si Yan still didn't give up. "There's no oxygen, no carbon dioxide either!"
The gecko perched on her head and patted it again. "Why are you so stubborn? If I tell you to plant, you plant!"
