Of course, the 'kill formation' that Wyatt Barnes inscribed with his current spiritual power and combined 'Inscriptions' had limited lethality, capable of only killing martial artists below the Seventh-Order of the Transforming Void Realm.
For martial artists above the Seventh-Order of the Transforming Void Realm, the 'kill formation' Wyatt Barnes laid out still couldn't kill them.
Not enough power!
The power of the Inscription formation was closely related to the mental strength of the Inscription master who inscribed and arranged it, and one couldn't go without the other.
"My mental strength is still too weak now... Only with great mental strength can I inscribe higher-grade 'Inscriptions,' and even arrange more advanced 'Inscription formations'!"
Wyatt Barnes sighed inwardly.
But he also knew there was nothing he could do about it.
"I can only wait until my mental strength improves before I upgrade the level of the 'Inscription formation' above."
