I can push my cultivation progress to the end

“Huh? There's light~”

Li Hai took three steps as two, and in the blink of an eye, he rushed to the desk with a gust of fierce wind.

Then he saw a scroll painting, mostly unfurled but gray and colorless, lying horizontally on the dark, square table.

It was the scroll axis of this painting that was emitting the red light just now.

“What is this thing?”

Li Hai stood in front of the desk, leaning over to observe carefully.

Then, with just one glance, he noticed that the gray scroll painting wasn't entirely blank.

In its corner, there was a small, slightly blurred rectangular pattern.

Next to this pattern, the words "Side Hall" were specifically noted.

At the same time, near the edge of the painting's center, close to the mounting, a line of small characters was also inscribed—[Netherworld Prefecture Gui You Cave Heaven Map].

“So, it's a map.”

Li Hai was somewhat puzzled, “But what's a map doing here?”

Unable to figure it out, he immediately moved towards the edge of the hall, wanting to see what was outside.

“Thirty zhang… sixty zhang… ninety zhang… one hundred zhang, here!”

After taking a few steps to the edge of the hall, Li Hai saw a tall, open doorway.

Without hesitation, he raised his head and stepped into the dark doorway.

As if passing through a thin mist, Li Hai instantly arrived in another great hall.

But strangely, this hall felt extremely familiar to him.

Whether it was the position of the relief murals or the arrangement of the tables, chairs, and utensils, this hall was exactly the same as the one he had arrived at earlier.

Especially the black desk at the front of the hall, and the red-glowing scroll painting lying horizontally on it, were exactly the same as in the previous hall, without the slightest difference.

To verify this guess, he strode towards the doorway of another hall.

Then, he arrived in yet another hall that was exactly the same in terms of furnishings and layout.

Li Hai refused to believe it, and once again crossed the hall and entered another doorway, and then once again arrived in the same hall as before.

Instantly, he understood:

“So that's it, this is actually a… hall that infinitely loops in space, no matter which doorway you enter, you will only return here in the end.”

Li Hai frowned and muttered, “This kind of magical effect shouldn't be possible with the abilities of the martial arts system, it must have been created with magic.”

Since he couldn't reach outside the hall, Li Hai simply restrained his temper and began to wander around here, wanting to find some rare treasures.

And sure enough, after searching around, he actually found some things.

Among these things, there were porcelain medicine bottles with completely blurred writing, a thick-backed knife about two and a half feet long engraved with strange dark patterns, a crimson crossbow with dozens of arrows scattered around it, and three silk books written in complex ancient characters.

It's worth mentioning that one of these three books is the incomplete 《Evil Spirit Earth Yin Absorption Method》 that Asu cultivated.

As for the other two, one is 《Moon Marrow Chain Shaping Art》, and the other is 《Iron Bucket Plate Clock Manual》.

Li Hai himself was also very strange, why the characters in this world were clearly different from Chinese characters, but he could understand them clearly and thoroughly.

To this, he could only attribute it to the power of the [Study Hard] system.

However, Li Hai, with his rough personality, would not bother with such small problems.

It's better to understand, and it doesn't matter if he doesn't understand, anyway, just find someone to practice, and when he has practiced it, he can copy it from the side, and the result will still be the same.

Getting off topic, in short, after reading and understanding the contents of these two books in detail, Li Hai completely understood what their functions and effects were.

First is 《Moon Marrow Chain Shaping Art》.

This book is similar to 《Evil Spirit Earth Yin Absorption Method》, it is for ghosts to practice.

That's right, this is another evil ghost art.

However, compared to the relatively broad content of the incomplete Yin Absorption Method, what this ghost art practices is very singular.

To sum it up, it is… it can allow ghosts to absorb the essence of moonlight at night, and refine it into moon marrow stored within the soul, and then leave it for free use during the day.

Whether it is used for attack and killing, or for defense, or for maintaining existence, all are possible.

In other words, this ghost art that relies on basking in moonlight to cultivate can effectively extend the ghost's battery life in areas outside of evil spirit lands, and can also effectively improve the situation where its abilities are severely weakened after leaving the evil spirit land.

As for the degree of improvement, it is currently unknown.

In general, this ghost art is extremely useful to Li Hai.

After all, it is impossible for this world to be full of evil spirit lands, but the convenience of ghost abilities does make it difficult for Li Hai to give up.

Fortunately, the appearance of this ghost art has provided a solution to this problem.

Li Hai believes that as he continues to acquire fragments of the strong, this 《Moon Marrow Chain Shaping Art》 will definitely be strengthened by him in the future to the point where no matter where he is, his ghost abilities will no longer suffer the slightest weakening, and may even be amplified and strengthened.

And the second book, 《Iron Bucket Plate Clock Manual》, is a genuine martial arts technique, and its level is not low, especially in terms of hard qigong and tempering the mind, it is clearly far beyond 《Beast Intent Demon Claw》.

Putting aside the extremely complex and arduous cultivation process of this technique, and the various medicinal materials that need to be used during the cultivation period, its true core meaning can be summarized in one sentence:

That is, the body is like an iron bucket, and the mind is like a plate clock.

This technique can be divided into seven levels from low to high.

Basically, each level needs to experience extremely painful physical training, as well as complex and difficult mind tempering.

The medicinal materials that need to be used during the period are even more diverse and varied.

In short, it is time-consuming, energy-consuming, and expensive.

However, once it is cultivated to its peak, then the practitioner will also become a leader among the steel bone realm martial artists.

Especially in defense, it will be several times stronger than ordinary steel-level martial artists, and the whole body, inside and outside, tendons, bones, internal organs, and viscera will be extremely strong and tough, just like real copper and iron casting.

In addition to physical strength, after reaching the seventh level of 《Iron Bucket Plate Clock Manual》, the mind strength will also far exceed the norm, and hypnosis or illusions in the usual sense will be meaningless to it.

The benefits brought about by high mind strength are not only this, it can also greatly improve the practitioner's will, perseverance, perseverance, and mind, and then become a steel person who is both physically and mentally 'hard'.

Without much hesitation, Li Hai sat down on the spot after reading these two techniques and began a new round of upgrades.
