The Mystic Yin Lightning Shield Talisman could be said to be a creation that Mu Fusheng was extremely satisfied with.
Not only did it have outstanding defensive capabilities, it had an unexpected killing trapping array power!
It was a pity that Mu Fusheng could not mass produce it with his current strength.
He could at most engrave two to three pieces every three to four days.
Even an Earth Immortal expert would have a headache if he had to cover his senior brothers, senior sisters, and junior brothers with this thing.
If the upper echelons of the Holy Talisman Sect knew what Mu Fusheng was thinking…
They would probably black out.
Ordinary Celestial Talisman Masters would need to spend a lot of effort and time to inscribe Immortal Realm talismans.
Yet Mu Fusheng could create two to three pieces every three to four days and was dissatisfied with it?
He even said that it could not be mass-produced?
