"Demon Summoning..."
After setting up the Demon Summoning rune array, Yin Ming selected the most conspicuous Soulstone from his storage pouch, pulled out the broken tooth embedded in it, and tossed the tooth into the center of the supernatural rune array.
He infused a wisp of mana into it. The sorcery runes engraved in the array flashed with black light, and the aura of the Abyss descended through it.
However...
He waited a long time.
Yet Red Nose never appeared.
Just as he was about to abandon this summoning attempt, a humanoid phantom suddenly appeared above the array.
It seized control of the Demon Summoning rune array and began frantically draining the mana from Yin Ming's body.
"What's going on?"
"With my current strength, how could casting a Zero-Ring spell still go wrong?!"
Yin Ming looked stunned. The Demon Summoning rune had no fixed target, but he was using a rune array from the alchemy civilization, along with a demon's token. The summoning's target was perfectly clear.
There should only have been two possible outcomes: a successful summoning, or a failed summoning because the target refused. Summoning a different demon should have been utterly impossible.
"..."
After a moment's hesitation, Yin Ming allowed his mana to flow into the Demon Summoning rune array. The aura of the Abyss enveloped an area several meters across, making the humanoid phantom slightly more solid.
Sensing the aura of life spilling from the array, he identified it as a Third-Ring war demon. Its true body could not descend through a Zero-Ring array, but it had successfully sent over a portion of its power.
It possessed roughly Second-Ring strength, enough to crush a First-Ring Warlock to death.
"Whooo..."
The war demon wore a full suit of black armor, its scarlet eyes showing through its helmet.
