Under the nurturing of the "Soul Nourishing Technique," in just two or three years, the black dog, though unable to speak, became intelligent enough to write, which made Li Ming very gratified.

But what kind of nonsense is this?

Menstruation.

Is this something a dog should understand?

What exactly has Black Dog gone through in the past two or three years?

I remember this was a male dog, and according to common sense, it couldn't be menstruating. So the black dog must refer to something recorded on the moonstone.

Li Ming looked at the black dog and said, "You mean you comprehended a kind of immortal technique from the moonstone, and its name is 'Menstruation'?"

The black dog nodded, a relieved smile on its face. Li Ming was good in every way, except for being a bit silly.

If she were a young girl, Black Dog felt he could lie to her a hundred times, and afterwards he wouldn't even have to treat her to spicy hot pot.

The black dog handed the moonstone to Li Ming, saying that good things should be shared and that one should not cultivate alone.

After all, Li Ming was his only companion here.

We need to help each other.

Seeing the black dog desperately trying to shove the moonstone into his hands, Li Ming was speechless for a moment and said, "I don't want it, you can cultivate it yourself."

However, the black dog wouldn't listen.

He still desperately tried to stuff the moonstone into himself.

Li Ming said helplessly, "I don't need it, go play by yourself."

He would never practice the techniques on the moonstone, no matter what. The name "Menstruation" sounded strange, and if he were to fight someone and they asked him what kind of immortal technique he was practicing...

How should I answer this?

Even if the other party doesn't know the meaning of those two words, Li Ming does.

Therefore, he strongly refused.

Seeing that Li Ming was not cultivating, the black dog frowned and wrote on the ground again.

"Good stuff. Once you've mastered it, believe it or not, it's incredibly powerful."

Li Ming shook his head.

The black dog did not give up and personally practiced the results of his two or three years of practice. As the magic was activated, a full moon appeared above the black dog's head.

The bright moon shines down, illuminating the world.

If you look closely, you can see the Moon Palace floating within the moon, followed by a black dog roaring at the moon, and brilliant light cascading down like a waterfall.

Suddenly, strange phenomena appeared.

Its size doubled, and dust flew everywhere.

The body surface was covered with terrifying images: the Vermilion Bird soaring, the Black Tortoise tearing through the sky, the Azure Dragon entering the sea, the White Tiger roaring, and the setting sun shining brightly.

The space where the black dog stood seemed to be torn apart by a force, the ground was cracked, and everything seemed to be floating and sinking within the area covered by the force.

This is the result of his two or three years of practicing "Menstruation".

Li Ming was also startled by the strange phenomenon of the black dog; it seemed to have some merit. However, he still refused, saying, "Stop messing around. I don't want this technique. You can cultivate it slowly on your own."

"Woof woof woof..."

The black dog bared its teeth at Li Ming, as if calling him an idiot.

It's such a good thing, why don't you learn it?

Okay, it will cultivate on its own.

Once he reaches the pinnacle of cultivation, he can capture Li Ming and use him as a mount. Wouldn't that be incredibly cool? The black dog thought to himself.

It felt that day was not far off.

Full of energy, he put away the moonstone, sat cross-legged on the ground, formed hand seals with his claws, and continued to cultivate the supreme immortal technique he had comprehended, "Menstruation".

A smile appeared on Li Ming's lips. This black dog was really interesting. He had beaten it up quite a bit before, but he didn't expect it to share good things with him first.

It seems I should beat it less in the future.

Li Ming withdrew his gaze, stopped cultivating, and took out the dragon-patterned black box from his Sumeru Ring.

I've been researching this for years, but I still have no clue what to do.

Over the past few years, we've tried everything, but we still can't open it. Maybe we should let Black Dog try.

He patted the black dog and said, "Didn't you always want this? Here, you can play with it for a few days."

The black dog glanced at Li Ming indifferently, took the dragon-patterned black box, and then threw it far away.

Li Ming's face darkened.

The black dog was seen writing the Three Character Classic on the ground with its paws:

Black box, misleading, unimportant.

Moonstone, carved with immortal techniques, I practice them to become the strongest.

If you don't believe it, you'll regret it later.

If you don't listen to advice, you're dead.

Li Ming finished reading what it had written, and although he had a lot to say, he couldn't say it, because the black dog had already said everything, leaving him with nothing to say.

With a flick of his wrist, a burst of spiritual energy shot out, and the dragon-patterned black box that the black dog had thrown out reappeared in his hand.

"You can slowly cultivate the Menstrual Immortal Technique. Sooner or later, you will be able to cultivate menstruation," Li Ming remarked.

"Woof woof..."

The black dog understood the first half of Li Ming's sentence, but was a little confused about the second half. However, it took it as Li Ming praising it and quickly wrote on the ground.

"Thank you for the compliment," the black dog wrote smugly.

"Uh." Li Ming said with a dark face, "Talking to you is like talking to a brick wall."

After saying that, he returned to the castle in the air.

He now feels that the black dog's intelligence is still not very good; it's a bit stupid and dull.

If he were a young girl, Li Ming felt that if he lied to her ten times in one night, it wouldn't be a problem if he didn't treat her to spicy hot pot in the morning.

Unfortunately, no.

He returned to his room, locked the door, and instead of sleeping or cultivating, he lay on the couch, took out the dragon-patterned black box, and placed it next to the dragon-patterned wooden plaque for study.

They are indeed made of the same material.

But how do we open the dragon-patterned black box?

There was absolutely no clue.

In the past two or three years, the strangest thing Li Ming felt was that the dragon-patterned black box would react every time he practiced the "Qi Refining Technique".

It radiated a dark, luminous glow.

But I just can't open it.

Li Ming planned to work on his Qi cultivation and use it to make breakthroughs, but unfortunately, all he got were layers of luster, and that was it.

He could sense that there was something extraordinary inside the black box.
