Flowing Spirit Rock was a very special material.
Using this material to refine weapons, the defensive ability of the spirit weapon refined was very strong.
What was even more amazing was that it could even return the strength of the opponent's attack.
As long as the opponent's attack did not exceed the defense of the Flowing Spirit Rock, he could return the favor.
The Flowing Spirit Rock could only be destroyed if it exceeded its defensive strength.
The more Flowing Spirit Rock there was, the stronger the defense would be.
If the spiritual weapon contained more than half of the Flowing Spirit Rock, it would be able to block the attack of a Level Six Martial Grandmaster!
If the spiritual weapon was held by a Sixth Grade Martial Grandmaster, it could even withstand the attack of a Seventh Grade Martial Emperor!
Therefore, the Flowing Spirit Rock was a very magical existence, and it was also a very expensive and rare resource.
