The first approach he tried was the most basic and simplest: chain detonation, or sympathetic explosion.
Multiple talismans of the same kind would take effect simultaneously.
Lei Jun began by experimenting with Blazing Flame Talismans.
After his comprehension rose to the Profound Clarity level, many of the difficulties in his earlier research had dissolved like ice under the sun.
Lei Jun's ideas gradually took on a rough form that could be put into practice.
Though truly activating and detonating multiple Spirit Talismans at once still placed exceedingly high demands on a cultivator's Magic Power and soul.
Even if it succeeded, the burden was immense.
That made it unsuitable for firing in many directions over a broad area.
But one Spirit Talisman could trigger the detonation of nearby Blazing Flame Talismans.
The angle and area of attack were relatively smaller, but the coverage and firepower would undoubtedly increase dramatically.
"Not bad, not bad. It has something of the feel of the Wind and Fire Linked City Talisman and the Boundless Sea of Fire Talisman."
Watching the sheets of flames before him explode continuously to either side, until a sea of fire spread across the ground, Yuan Mobai nodded faintly.
The two types of Spirit Talismans he mentioned were both direct-line high-grade Spirit Talismans of the Celestial Master Mansion, which only cultivators of the Third Heaven and above could practice.
Though there had been many outstanding figures throughout the Celestial Master Mansion's history who improved basic Spirit Talismans, more people preferred to devote their time and energy to cultivation, high-grade Spirit Talismans, and even higher-level Divine Ability Dharma Talismans.
Lei Jun had heard of this before, but he had no intention of waiting until he reached the Fourth Heaven before practicing similar high-grade Spirit Talismans.
It was not because he was impatient.
