The World Tree hadn't taken root yet, or else Negris would have truly been frightened. However, Ange was evidently working hard to cultivate it. He first saturated the ground with water, planted the seed, and then pointed at it with his finger.
No movement or signs of germinating came from the seed for quite some time.
Well, it wasn't so easy to grow a World Tree. However, Ange was not discouraged. If growing a simple mushroom required a control group, then the World Tree certainly required more intricate care and consideration
Bearing this in mind, Ange set up several hundred growth combinations, with different types of soil including pure volcanic ash, bone meal mixed in, burnt plant ash mixed in, and rural household compost mixed in. The pH of the soil, its ability to let water pass through, and a dozen other combinations were set up.
