It seemed simple enough to make one himself when he got back, and he didn't want to waste more space in his system backpack.
After finishing his tour of Baek Wonyeon's lab, Seo Woo was already eager to show Kim Haru around his own research lab.
However, there wasn't much Kim Haru could do this time. Even though potatoes could sprout without soil, they still needed to be buried in the ground to grow and mature properly. Unless the soil had a very low mutagenic virus content, the potatoes that grew would inevitably carry the virus.
The cabbages could at least use rainwater with minimal virus content, but there was no such solution for the potatoes.
Moreover, the potato tubers stayed in the soil from growth to maturity, which meant they would absorb much more of the virus than the cabbages or soybeans.
