According to the *Xianyi Tianjing*, the ten-thousand-year spiritual wood bears fruit once every three thousand years, and its fruit is known as the Yimu Spiritual Core.
The Yimu Spiritual Core itself possesses an immensely rich Wood Element Spirit, comparable to a supreme treasure of the wood element, and can even be considered a seed.
Such an item is a supreme treasure even in the cultivation world.
