“Oh? Light!”
Li Hai took three steps as two, and in the blink of an eye, he rushed to the table with gusts of biting wind.
Then he saw a scroll painting, mostly unrolled but gray and colorless, lying horizontally on the large, dark, rectangular table.
The red light that had just bloomed was precisely from the axis of this painting.
“What is this thing?”
Li Hai stood before the table, leaning over to observe carefully.
With just a glance, he noticed that the gray scroll painting was not entirely blank.
In its corner, there was a small, slightly blurry rectangular pattern.
And beside this pattern, the words 【Side Hall】 were specifically noted.
At the same time, near the outer edge of the scroll painting’s center, close to the mounting, a line of small characters was also written—【Naihe Prefecture Guiyou Cave Heaven Map】.
“So it’s a map.”
Li Hai was somewhat puzzled, “But why is a map placed here?”
Confused, he immediately moved forward towards the edge of the great hall, wanting to see what was outside this hall.
“Thirty zhang… sixty zhang… ninety zhang… one hundred zhang, reached!”
After taking a few steps to the edge of the great hall, Li Hai saw a tall, open doorway.
Without much hesitation, he stepped into the pitch-black doorway with his head held high.
As if passing through a thin veil of mist, Li Hai instantly arrived in another great hall.
But strangely, this great hall felt extremely familiar to him.
Whether it was the position of the relief murals or the arrangement of tables, chairs, and artifacts, this hall was identical to the place he had arrived at earlier.
Especially the black table at the very front of the great hall, and the red-glowing scroll painting lying horizontally on it, were exactly the same as in the previous hall.
“How peculiar.”
A thought suddenly popped into Li Hai’s mind, “Could it be that the halls behind will also be like this?”
To verify this conjecture, he strode towards the hall entrance in another direction.
Then, he arrived in yet another hall, identical in both furnishings and layout.
Li Hai refused to believe it, and once again traversed the hall into another doorway, then arrived once more in a hall exactly the same as before.
Instantly, he understood:
“So that’s it. This is… a hall that infinitely loops in space. No matter which doorway you enter, you will always return to this place.”
Li Hai frowned and murmured, “This kind of miraculous effect shouldn’t be achievable with Martial Artist System abilities, right? It must have been done with Spell.”
Since he couldn’t reach anywhere outside the great hall, Li Hai simply settled down and began to wander around, wanting to see if there were any rare treasures here.
And sure enough, after searching around, he really did find some things.
Among these items were porcelain medicine bottles with completely blurred writing, a thick-backed saber about two and a half feet long engraved with strange dark patterns, a reddish 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 was precisely the incomplete part of the Evil Spirit Earth Drawing Yin Method that A Su Cultivates.
As for the other two, one was the Moon Marrow Chain Technique, and the other was the Iron Bucket Clockwork Manual.
Li Hai himself found it strange why he could understand and comprehend the texts of this world, even though they were clearly different from Chinese characters.
He could only attribute this to the great power possessed by the 【Study Hard】 System.
However, the straightforward Li Hai wouldn’t bother dwelling on such minor issues.
It’s better if he can understand it, but it doesn’t matter if he can’t; he can just find someone to Cultivate it, and once they succeed, he can copy it, leading to the same result in the end.
Getting back to the point, after thoroughly reading and understanding the contents of these two books, Li Hai completely understood their functions and effects.
First, the Moon Marrow Chain Technique.
This book is similar to the Evil Spirit Earth Drawing Yin Method; it is for ghosts to Cultivate.
That's right, this is another evil ghost Spell.
However, compared to the relatively broad content of the incomplete Yin Drawing Method, the things Cultivated by this ghost Spell are very singular.
To summarize, it allows ghosts to draw moonlight essence at night and refine it into Moon Marrow stored within their souls, which can then be freely used during the day.
It can be used for attack and killing, for defense, or for sustaining one's existence.
To put it plainly, this ghost Spell, which Cultivates by basking in moonlight, can effectively extend the duration of ghosts outside Evil Ground and also effectively improve their severe decline in ability after leaving Evil Ground.
As for the extent of improvement, it is currently Unknown.
Overall, this ghost Spell is extremely useful to Li Hai.
After all, this world cannot be Evil Ground everywhere, but the convenience of ghost Dao abilities indeed makes it difficult for Li Hai to abandon them.
Fortunately, the emergence of this ghost Spell provided a solution to this problem.
Li Hai believed that with the continuous acquisition of powerful fragments, this Moon Marrow Chain Technique would definitely be strengthened by him in the future, so that no matter where he was, his ghost Dao abilities would no longer suffer any weakening, and might even be amplified and strengthened.
And the second book, the Iron Bucket Clockwork Manual, is an out-and-out Martial Artist Cultivation Technique, and its level is not low, especially in terms of hard qigong and tempering the mind, it is clearly a significant step above the Beast Intent Demon Claw.
Putting aside the extremely complex and arduous Cultivation process of this Cultivation Technique, and the various medicinal materials required during Cultivation, its true core Profound Truth can be summarized in one sentence:
That is, the body is like an iron bucket, and the will is like a coiled bell.
This Cultivation Technique can be divided into seven levels from low to high.
Each level basically requires experiencing extreme physical torment and complex and difficult mental tempering.
The medicinal materials required during this period are even more varied and diverse.
In short, it is time-consuming, energy-consuming, and money-consuming.
However, once Cultivated to its peak, the practitioner of this Cultivation Technique will also become a standout among the Steel Tendons Iron Bones Martial Artist group.
Especially in defense, he will surpass ordinary Steel Grade Martial Artist by several times, and his entire body, inside and out, including muscles, bones, and internal organs, will be extremely strong and tough, like true bronze poured and iron cast.
In addition to physical strength, after reaching the seventh level of the Iron Bucket Clockwork Manual, mental strength will also far exceed the norm, and generally speaking, hypnosis or illusions will be meaningless to him.
The benefits brought by high mental strength are not limited to this; it can also greatly enhance the Martial Artist’s will, perseverance, persistence, and mindset, thereby turning them into an “iron” person who is incredibly “hard” both physically and mentally.
Without much hesitation, Li Hai sat down on the spot after finishing these two Cultivation Techniques and began a new round of upgrading.
