Three months passed since the last time Leon saw Darya, at least he didn't receive any visitors in the meantime. He already had an idea what Donan intended to do with Darya, but Leon still imagined he would torture her to obtain information. The fact that no one bothered was a proof that probably didn't happen… or if it did happen, she didn't open her mouth to talk about it. But Leon didn't want to imagine his friend enduring torture.
For a few days, Leon thought of trying to discover a way to upgrade the blue angel plants, but soon he gave up on the idea. Although there were many differences in the world in different stages of assimilation, it looked like blue angel plants didn't change or could be changed. Mana was the lifeline of the people of that world, so they probably tried to find a way to improve their plants… if they didn't succeed in seven decades, the chances of Leon succeeding in months were low. Besides, he wasn't a botanist.
