I Reincarnated as a God Tree

After reincarnation, you have become a tree. This tree could be gentle: soaking in the rain showers, breathing the morning air, with birds nesting upon you and wild beasts resting under you. This tree could be miraculous: perhaps your branches can be crafted into arrows capable of slaying dragons, your leaves can save a warrior on the verge of death, your bark is harder than steel, and your roots reach all the way into the core of the world. This tree could be divine: maybe you can control the weather and temperature, be worshipped by villagers, gather the power of belief, and finally ascending to become a tree god.
