Li Ming had no intention of exposing it yet, and wanted to see how things went. Half a month passed in the blink of an eye, and the black dog was in better spirits, with very bright eyes.

This is naturally thanks to the "Soul Nourishing Technique".

Three months later.

The black dog underwent a dramatic change. First, it was no longer listless; it was full of energy and enthusiasm all day long.

Furthermore, his unusual phenomena became even more outrageous; the crescent moon above his head was now slowly becoming fuller as he cultivated.

Li Ming grew increasingly curious, sensing that the black dog was developing in a positive direction.

Two years have passed in the blink of an eye, and Li Ming's dragon-patterned black box remains unsolved, but the black dog has almost turned the moon above its head into a full moon.

That black dog's got some skills.

Li Ming stared at the moonstone, but couldn't figure it out. He felt like there was nothing there. How did the black dog manage to research it?

That's really bizarre.

Another six months have passed.

On that day, Li Ming was cultivating, and beside him was a black dog that was also cultivating. It slowly opened its eyes, and the flames in its eyes disappeared.

The moon overhead was completely round.

Then, it woke up Li Ming, who was cultivating, and handed him the moonstone.

"What do you mean?" Li Ming stared at the black dog.

"Woof woof..." The black dog handed the moonstone to Li Ming, gesturing for him to examine it.

There's nothing there.

"Woof woof..." The black dog got a little anxious and started barking. There was a cultivation technique on the moonstone, which it had personally verified to be cultivable, and it had already mastered it.

Seeing that Li Ming couldn't understand.

The black dog frowned and thought for a moment, then scratched the ground and wrote down the mental cultivation technique it had comprehended.

Then two very prominent words appeared before my eyes:

"Menstruation".
