章節 447: The First Spiritual Beast Level Familiar

"Meow!"

A shrill scream sounded, as if someone was torturing a weak cat.

As the owner of this scream, the Shadow Cat was happy.

The Shadow Cat sensed that the pain was accompanied by an increase in its strength.

In less than fifteen minutes, his strength had increased from Demon General to Demon Venerable.

If this continued, even the demon kings would not be able to stop him.

When he thought of the glory he would gain after his strength increased, the pain was nothing.

When the Underworld Dragon saw this, he could not help but smack his lips. Good heavens, he could still smile in such pain. This new companion was not ordinary.

It seemed like…Don't spend too much time with it in the future.

It was still the winged tiger that knew how to enjoy.

As time passed, the Shadow Cat's strength continued to rise. After two hours, the Shadow Cat let out another miserable scream.
