When Chen Mobai left the Great Toon Spirit's consciousness space, two deep azure wooden tablets had appeared in his hand. They were none other than Great Camphor Tree Heartwood.
For a talisman to possess a Heaven Spirit Root, it also required corresponding Xiantian essence qi of that attribute.
Originally, Chen Mobai did not have any, so he had not thought about asking for Sixth Order Tree Heartwood.
But not long ago, the two experts Yuanxu and Venerable Sanjue had made a major breakthrough while researching Immortal Technique: Mend Heaven. They discovered that the Xiantian essence qi representing a Heaven Spirit Root could be manufactured through artificial means.
The key lay in the Immortal Spirit Qi Chen Mobai had previously asked Yuanxu to research. This qi possessed the nature of Tai Chu Qi and could be artificially guided and transformed into any kind of essence qi.
Of course, transformation using Immortal Spirit Qi alone would not work. During the transformation process, Great Dao Power of the Five Elements Attribute also had to be infused. Only by combining the two could one synthesize the Xiantian essence qi representing a Heaven Spirit Root.
That they were able to discover this point was not only because of Immortal Technique: Mend Heaven, but also because Yuanxu had thought of the formula for Heavenly Pure Water. The latter had been refined by the Spirit Venerable condensing Water Element Great Dao Power. By extending this theory to the Five Elements, and after tens of millions of simulations by the Square Inch Book, they succeeded.
Chen Mobai greatly praised this achievement as well.
If this had been over in the Sky River Realm, even if they were given the same conditions, it likely would have been impossible to research such a result in a thousand or ten thousand
