According to Yin Chengdao's "memory", the method he played last night, which compressed the internal space of the clay ball and changed its molecular arrangement, was unprecedented in this world.
Neither the "Undying Five Elements Body" earth spirit body cultivation nor the other earth-type spiritual methods in Yin Chengdao's memory could change the arrangement of earth molecules, and no earth-type spiritual cultivator could do it, at least not Yin Chengdao himself.
It seems that I have unknowingly created a new earth-based spiritual technique.
This kind of earth-based spiritual magic, which directly changes the molecular arrangement and turns soil into stone, may not be of much value in actual combat, but it has great value in daily life!
To verify his idea, Lin Yisheng tested the next level of earth-based spiritual magic, "Earth Spike Technique".
"Earth Spike Technique" is the only low-level earth-based spiritual technique that Yin Chengdao knows, which novice spiritual disciples can use to actively attack opponents.
Lin Yisheng possesses spiritual energy roughly equivalent to a level 5 spiritual master. After learning to sense and manipulate earth spiritual energy last night, he is now capable of using the "Earth Spike Technique".
The so-called "ground spike technique" involves causing a cluster of stalagmites-like spikes to erupt from the ground and pierce the opponent's feet. If someone is not careful, they might even have their anus pierced, making it an extremely insidious and vicious technique.
While mobilizing the spiritual energy within his body, he performed strange techniques and then focused his spiritual awareness on the ground.
Half of his spiritual power was drained away as if water had been pumped out, and the earth elemental energy around his body began to fluctuate wildly.
Before long, stone spikes, each ten feet long, as thick as an arm, with sharp tips and shaped like bamboo shoots, rapidly emerged from the ground in front of them.
After careful counting, there were a total of twenty-two stone spikes that emerged, covering an area of nearly five square feet, and they were distributed rather densely.
Successfully practiced it on the first try!
It seems I really am a genius with an earth-attribute physique... no, a monstrous spiritual cultivator!
Being a spiritual practitioner is definitely more interesting than martial arts!
Looking at the twenty-two stone spikes standing on the ground, Lin Yisheng suddenly had another idea: what if he didn't make stone spikes, but instead made a wall?
Just do it!
Lin Yisheng only rested for a little over half an hour before his mental strength returned to normal, and then he used the "Earth Spike Technique" again.
This time, however, he added a consciousness, causing the earth elemental energy to abandon shaping the underground soil into the form of stalagmites and instead form the shape of a flat wall.
As expected, the earth elemental energy began to move according to Lin Yisheng's will.
In less than fifteen minutes, a wall appeared out of the ground.
It is three zhang high, three zhang long, and half a zhang thick, with at least half a zhang of foundation underground.
The surface is smooth and flat, and the internal molecules are arranged tightly and firmly.
Although it is still an earthen wall, it is as sturdy as a stone wall and can definitely withstand a thousand pounds of impact without collapsing.
It was a success!
Looks like I've created a new earth-based magic spell. What should I call it? Hmm, let's call it "Earth Wall Technique"!
Such "earthen wall techniques" would be an extremely effective defensive weapon.
Although Yin Chengdao had a similar "Earth Shield Technique" among the first-level earth-type spiritual arts, it only formed an earthen shield of less than half a square zhang in front of him, which would shatter with a single blow. Its defensive power was far superior to the "Earth Wall Technique" created by Lin Yisheng.
However, Lin Yisheng was not entirely satisfied with this.
He didn't want to build an "earthen wall," but rather a more solid and sturdy "stone wall."
Thinking of the game he played yesterday where the little earth ball turned into a stone ball, Lin Yisheng, having rested enough, once again focused his mind, driving the earth spirit to compress the molecular structure inside the earthen wall, changing its arrangement, and constantly drawing in new soil to fill the gaps created by the compression.
Half an hour later, the earthen wall slowly transformed into a stone wall that remained the same size but had a more compact, solid, and harder internal structure.
Because Lin Yisheng did not put in the effort to remove the impurities from the earthen wall this time, the shape and structure of this stone wall are different from the small earthen ball that turned into a small stone ball.
Without the eggshell-like metallic outer shell, the overall structure of the stone wall became black with variegated patterns, much like the Xuanheishan stone used by the Wu family to build their houses. However, its strength was far greater than that of Xuanheishan stone, at least three times stronger.
This level of black stone is strong enough to be used directly for the main walls of a building, and it is even more aesthetically pleasing than real black stone.
Looking at the stone wall in front of him, Lin Yisheng couldn't help but think of building himself a new stone house to replace the wooden shed he had built yesterday.
During the years he served as a slave to the Wu family, Lin Yisheng participated in the construction of several houses. Although he was only a porter and not a construction worker, he still learned about the basic structure and essentials of houses.
The first step in building a house is to lay a foundation. If the foundation is unstable and not solid, even the sturdiest house will be like a castle in the air and will collapse in a few days.
After choosing a spacious and decent location, Lin Yisheng began to use the newly comprehended earth-to-stone technique to transform the ground.
It took him a full hour to transform the ground, which was about forty square meters in area and three zhang deep, into a solid foundation that resembled all-rock.
Exhausted of his mental energy, Lin Yisheng sat down and practiced "spiritual consciousness meditation" to restore his mental energy. Then, he began to build the walls on the foundation.
They worked until it was completely dark again, and a simple stone house, three zhang high, with only one room and one living room, a door but no windows, and looking as if it had been carved from a huge rock, was "built".
Lin Yisheng looked at his "work" and was quite satisfied. Unfortunately, he did not know wood-type spiritual magic and could not quickly create doors and windows. He could only use a fourth-grade spiritual weapon sword to cut some tree branches and make a simple door and window.
In addition to the house, Lin Yisheng also used earth-based spiritual magic to create a stone bed.
Resting in this new house tonight will definitely be much safer and more comfortable than the wooden shed we built yesterday.
Lin Yisheng discovered that after spending almost a whole day building a house, he was becoming more and more proficient in using earth-based spiritual techniques. The speed at which earth spiritual energy gathered was several times faster, and even his mental strength had improved. In the end, it only took him a dozen or so breaths to build the stone bed.
This speed was unimaginable yesterday!
It seems that using earth-based spiritual techniques to build houses is also a very good cultivation method.
If I could build a city using earth-based spiritual magic, my spiritual magic cultivation might break through the Spirit Warrior level and reach the Spirit Master level, or even the Great Spirit Master level.
The constant depletion of his mental energy left Lin Yisheng feeling somewhat tired. After taking out some food from Yin Chengdao's spatial bag and eating it, he spread the animal skin blanket on the bed and fell asleep again.
Lin Yisheng slept soundly that night, without suffering from insomnia or having nightmares.
