Floating Shuttle Devious Kill

The stability of the mechanical arm effectively avoided interference from the human heartbeat, slight muscle tremors, and the like. Combined with the Space Iron Ring's two functions, Space Scissors Absolute Cut and Space Precision Absolute Processing, it ensured that the magic patterns were engraved with a precision far beyond the limits of human fingers.

"Scratch, scratch, scratch..."

A faint sound rang out. Under Richard's control, the Space Iron Ring lightly passed over the surface of the warhead, creating one fine line after another. They curved, twisted, and continuously extended.

"Scratch, scratch, scratch..."

The sound continued as Richard used the mechanical arm to carve line after line.

After working for several hours, he finally completed the magic pattern for the Three-Ring Spell Baruk Flame. Richard let out a long breath. The moment his body relaxed, dense beads of sweat seeped from beneath his skin, and it took him quite a while to wipe them dry.

After resting briefly, Richard drank some lightly salted water to replenish his fluids, then walked to a corner of the laboratory.

There stood a tall rack. He pulled out an iron box from the middle shelf, opened it, and took out a small ingot of pure silver.

He placed the pure silver ingot into a crucible and heated it with flames.

Silver's melting point was only 961.78°C, not even 1,000°C. Before long, the silver turned into molten liquid.

With a wave of his hand, Richard cast a spell and controlled the molten silver as it flew from the crucible toward the warhead engraved with magic patterns. Carefully, he used it to evenly fill the engraved magic pattern circuits.

This was a method Richard had learned from Veisha Secrets. By filling the magic pattern circuits with special magically conductive metals, one could stabilize them, reduce the time
