A talisman wanting to have Heavenly Spiritual Root requires corresponding attribute innate energy.
Originally, Chen Mobai did not have it; hence, he didn't think about needing the Sixth Rank Tree Heart.
But not long ago, two experts, Yuan Xu and Three Extremes, made a significant breakthrough while researching the Immortal Skill of Patching Heaven, discovering that the innate energy representing Heavenly Spiritual Root could be artificially synthesized using the acquired method.
The key was that previously, Chen Mobai had Yuan Xu research Immortal Spirit Qi. This essence with the nature of Tai Chu Qi can be artificially guided to transform into any kind of energy.
