Crafted by the Jade Immortal.
Generally speaking, it's rare for a Talismanic Soldier refined by an Immortal to reach the power of the same level—it's impossible, the materials just can't keep up.
If the Jade Immortal were to refine a Talismanic Soldier of the Jade Immortal level, it would require obtaining Fierce Beast Skin and Fierce Beast Blood of the same level, which is extremely difficult. Besides, how much would such a Talismanic Soldier enhance one's combat power?
There is an enhancement, but it's very weak.
Refining for future generations?
Who would be willing to go to such lengths? Don't they need to cultivate themselves?
Moreover, refining Talismanic Soldiers consumes a large amount of Soul Force, which affects one's own cultivation. Even someone as strong as Master Heitie would only bestow Silver Spirit level Talismanic Soldiers to his direct descendants.
This shows how difficult it is to refine advanced Talismanic Soldiers.
