At this point, the first level of the Netherworld Ascension Method was completed.
The Dantian acupoint was first opened.
Wang Lin calmed himself down and mobilized one-third of the Yin Qi outside his Dantian to attack it.
The Yin Qi did not enter the Dantian, but surrounded the entire black hole and began to attack it from the outside.
As the attacks went on, although he suffered many casualties, the frigid air currents were still infatuated. They continued to attack his Dantian fiercely again and again, and they became fiercer and fiercer as the battle went on.
After a long time, the black hole in the Dantian could not bear the pressure and gradually showed signs of collapse. Wang Lin immediately mobilized one-third of the Yin Qi again and destroyed the Dantian acupoint in one go.
In an instant, a sharp pain came. The moment the Dantian acupoint collapsed, the mutated spiritual power in the Dantian immediately flowed out and dissipated in every inch of his muscles and bones.
Wang Lin did not even blink and mobilized the Yin Qi again to attack the acupoint.
This time, it took much longer than the first time. Seeing that the Yin Qi seemed to be running out of energy, Wang Lin used the last one-third. After being replenished, the Yin Qi immediately formed a whirlpool that was several times bigger than the black hole in the Dantian, spinning rapidly.
The faster the whirlpool spun, the more urgent it was to attack the acupoint. Time passed quietly and night fell.
Wang Lin was still in the final stage of the acupoint attack. The Yin Qi whirlpool in his body was spinning at an extremely fast speed. Because it was so fast, only a nebula-like whirlpool could be seen in the Dantian. It seemed to be spinning slowly, but in fact, it was far beyond the naked eye's limit.
At midnight, the Yin Qi became thicker. At this time, Wang Lin's body was like a black hole. As the whirlpool in his body spun, all the Yin Qi within ten feet of his body was madly sucked in.
The area within ten feet seemed to have become a meat grinder of Yin Qi, sucking in the Yin Qi almost infinitely.
When this huge amount of Yin Qi was sucked into Wang Lin's body, it immediately joined the whirlpool in the Dantian. The whirlpool grew bigger and bigger until it almost broke through the limits of Wang Lin's body and grew infinitely.
He was immediately shocked and wanted to stop, but he found that the vortex in his body was already out of control. He could only watch as it continued to grow.
Anxiety surged in Wang Lin's heart. The Netherworld Ascension Method did not have any relevant records regarding the current situation in his body.
Wang Lin didn't know that the reason why the Netherworld Ascension Method was called a strange skill was because it had too many strange changes. Some of these changes were extremely beneficial to the cultivator, and some would cause the cultivator to lose the skill and die.
Now that Si Tu Nan was asleep, Wang Lin had to take care of everything himself.
As the vortex grew, its suction force also became more and more intense. The surrounding area of a hundred feet rapidly expanded. This was a vicious cycle. The larger the vortex, the wider the distance it could expand. The larger the vortex was, the faster the vortex could absorb the cold Yin energy.
Twenty zhang, thirty zhang, fifty zhang, seventy zhang, one hundred zhang …
Within a radius of a hundred feet, the cold Yin energy surged like it was boiling. The strange change within a hundred feet caused the flow of the cold Yin energy in an even larger area. Within a thousand feet, the cold Yin energy was moving as if there was an invisible hand.
Wang Lin had completely lost control of the vortex. After an unknown amount of time, the Dantian in his body was suddenly enlightened.
This was the second time his Dantian was enlightened. Just like the first time, a black hole appeared the moment the Dantian was enlightened, and the cold vortex immediately sank into it. The strange change in Wang Lin's body immediately caused all the cold Yin energy within a radius of a hundred feet to change.
If the vortex in Wang Lin's body was previously endlessly absorbing the cold Yin energy, then now that the black hole in his Dantian appeared, this absorption immediately became devouring!
In an instant, the cold Yin energy within a radius of a hundred feet was instantly devoured, turning into a vacuum belt. The sudden change immediately caused a larger change, and the range of the devouring became wider and wider. One hundred feet, one hundred and fifty feet, two hundred feet, three hundred feet, five hundred feet, seven hundred feet, and finally more than ten thousand feet.
At this time, if one looked from the sky, one would see an extremely strange scene. Within a thousand feet, all the cold Yin energy was rolling like a rising tide, gathering in the center …
In the depths of the ruins, the blue-skinned strange man grabbed the corpse of a wild beast and tore the flesh. He had just swallowed a piece of flesh connected to a blood vessel when he suddenly turned his head and stared at the direction of Wang Lin. With a look of horror in his eyes, he hurriedly dropped the food in his hand and rushed towards Wang Lin like a frightened monkey escaping from a rabbit.
Not long after, he slowed down a little and sensitively found that the cold Yin energy around him was flowing rapidly forward. He hesitated for a moment and continued to move forward. When he was three thousand feet away, he stopped, and the look of horror in his eyes became more intense.
As for Wang Lin, the moment his dantian was opened, the mutated spiritual power in his body quickly gathered towards the black hole in his dantian and immediately assimilated and fused together.
At the moment when the spiritual power was assimilated and fused, he used his perception of the spiritual power to finally grasp control of the cold Yin vortex again. However, the degree of control was extremely small, and it was impossible to stop the flow of the cold Yin energy in his dantian.
Wang Lin gritted his teeth and decided not to stop devouring the cold Yin energy. Instead, he controlled the increasing cold Yin energy in his body and began the third opening breakthrough, entering the third level of the Underworld Ascension Method!
Under the guidance of Wang Lin's control, the huge amount of cold Yin energy in his dantian immediately began to open the aperture. His dantian instantly collapsed, turning into specks of blue light and dissipating. However, within the blue light, a dark blue crystal slowly appeared. This crystal was attacked by the cold Yin energy, and its color became darker and darker until it became completely green.
The third Aperture Opening Breakthrough was easily completed.
A cold core appeared in Wang Lin's dantian.
Countless tentacles extended from the cold core and spread to every part of Wang Lin's body.
The mutated spiritual power in his body quickly changed with the appearance of the cold core.
At this time, the cold Yin energy was still very thick. Wang Lin had a feeling that if he allowed the cold Yin energy to devour him, he would explode from the cold Yin energy. This feeling gradually became real as time passed, and a faint feeling of swelling came from his body.
Wang Lin gritted his teeth again, and his eyes revealed a look of desperation. He once again pushed the cold Yin energy to enter the fourth level of the Underworld Ascension Method!
Situ Nan had once pointed out that the first, fourth, and seventh levels of this method were extremely difficult to cultivate. This was because these three levels were the first to open the dantian, Qi Sea, and Ancestral Aperture.
Originally, according to the requirements of the Underworld Ascension Method, the first three levels had to be completely consolidated and the cold core had to be nourished in the dantian. Only after it had reached a certain level could it be attempted to open the aperture.
However, now that the spiritual power in Wang Lin's body had merged with the huge amount of cold Yin energy, the arrow on the bow had to be fired. Therefore, he began the opening breakthrough of the fourth level of the Underworld Ascension Method!
At the chest, he opened the Qi Sea acupoint!
The cold Yin energy in his dantian rose like a whirlpool and slowly rose. After a long time, it finally arrived at the Qi Sea acupoint and immediately began to spin crazily.
The Qi Sea acupoint was like a bottomless pit, quickly absorbing the cold Yin energy in the whirlpool. The opening breakthrough failed again and again, and the sky gradually became brighter.
The cold Yin energy within a radius of a thousand feet slowly dissipated, and finally, it completely disappeared.
The Qi Sea acupoint in Wang Lin's chest was still the same. At this time, he had a very deep impression of the Underworld Ascension Method's description of the high success rate of opening the aperture. He had continuously tried to open the aperture more than a hundred times, and every time he failed, the cold Yin energy would be consumed a bit.
The huge amount of cold Yin energy was gradually used up after more than a hundred attempts. In addition, the sky was bright, and the cold Yin energy within a thousand feet was completely gone. Without the supplementary power, the remaining cold Yin energy in Wang Lin's body was slowly absorbed by the cold core.
That night, Wang Lin had absorbed too much cold Yin energy, and his own spiritual energy had almost completely changed during the fusion, becoming completely cold Yin energy.
In terms of quantity, Wang Lin could now clearly feel that the cold Yin energy in his body had more than doubled, reaching the peak of the early stage of Foundation Establishment.
He opened his eyes and thought back to everything that happened last night. Although he was shocked, he was more concerned about the pros and cons of this cultivation method.
The abnormal cultivation that happened last night opened a new path for Wang Lin.
The advantages of this cultivation method were self-evident. As for the disadvantages, it was too dangerous. If he was not careful, he would explode. However, with this experience, Wang Lin believed that next time, he would definitely have a plan, step by step, and reduce the risk to the minimum.
"It seems that this temporary residence needs to be changed. Although I absorbed a lot of cold Yin energy last night, the quality was not high enough to increase the success rate of opening the aperture."
Wang Lin muttered to himself. Right now, the success rate of opening the aperture was very low. According to the Underworld Ascension Method, the higher the quality of the Yin energy, the higher the success rate.
Wang Lin remembered when he tested the quality of the Yin energy a few months ago, the source of the healing pillar, the tower shaped building, was high quality. He made a decision in his heart.
At the same time, the sky outside the forest suddenly darkened. An old man emitting a destructive aura silently appeared. His face was gloomy as he stared at the forest below him. His eyes were filled with killing intent.
"Li Er, grandfather has come to get revenge for you."
The person who came was the Teng family's ancestor, Teng Huayuan. He had been using his senses and curses the entire time, but it was as if there was a layer of fog blocking his senses. He was unable to determine the exact location of the other party. He only knew that the other party was in the forest below him.
Speaking of this forest, unless it was absolutely necessary, Teng Huayuan really didn't want to go in. With his current cultivation level, he could clearly feel that there was a powerful existence inside the forest that even he didn't dare to provoke.
However, Teng Li's death made it so that he couldn't care less. Teng Huayuan secretly thought that if he went in and didn't touch a single blade of grass or tree, then that powerful existence wouldn't pursue the matter too much.
After hesitating for a bit, he clenched his teeth and charged into the forest.
In the depths of the forest ruins, a corner of a coffin was silently lifted. A withered hand flickering with a purplish-black light slowly reached out and clenched its fist. Immediately, a purple ball of lightning condensed in its hand, giving off a dangerous aura.
"The 100 year time limit is approaching. My master, last time you escaped by throwing away your body, but this time you won't be able to escape!"
