Chu Yunfan opened the jade box. There was nothing else inside except for a green dew-shaped object. It was about the size of a thumb. Even though it was sealed by layers of barriers, Chu Yunfan could still feel a dense life force from this item.
'Is this Wood Spirit Essence?' Chu Yunfan's eyes lit up.
With the memories of the Alchemy Emperor, Chu Yunfan had the support of a top emperor. There were very few things in the world that were unknown to him.
Not to mention, it was the Wood Spirit Essence. Even the Alchemy Emperor did not have much Wood Spirit Essence back then. Wood Spirit Essence was the purest wood power in the world that could only be born under extremely special circumstances.
This Wood Spirit Essence was extremely precious. Just one drop could extend a person's lifespan by 20 years, and this was only one of the functions of the Wood Spirit Essence.
