Wang Lin suddenly had a bold guess in his mind, one day, many people were sitting at the dinner table, and suddenly disaster struck, and without them noticing, the entire city turned into dead ruins.

At this time, a trace of cold aura gradually emanated from the ruins, and this aura became heavier and heavier, and finally almost solidified into substance.

"Looking at the scale of this ruin, I'm afraid that the place with a population of no less than 10 million and tens of millions of dead people should be the best place of the Yellow Extreme Yin among the four places of Heaven and Earth. ”

Situ Nan once gave a detailed explanation of the land of extreme yin during Wang Lin's retreat. There are four types of extreme yin, namely heavenly yin, earth yin, xuanyin, and yellow yin.

The land of yellow yin is the simplest, the place where a large number of living beings die is the land of yellow yin, and the more dead people, the better the land of yellow yin.

There are some difficulties in the Xuanyin Land, and most of them only appear in extremely cold places.

The earth yin is more difficult, and it takes a great chance to encounter it, after all, the so-called earth yin is the breath that emanates from the abyss underground.

As for the heavenly yin, it is basically impossible, because in order to form the heavenly yin land, it is necessary to have the earth, the xuan, and the yellow at the same time, which will produce a wonderful transformation and turn into the heavenly yin land.

The higher the quality of the Extreme Yin Land, the greater the benefit to cultivators.

Wang Lin immediately pinched the trick with his right hand, and there were words in his mouth, and suddenly a trace of red light condensed in front of him, and finally formed a red ball of light.

This is a spell specially used to test the quality of the Polar Yin Land, according to the color of the light ball, there are four kinds of light, which are purple, blue, silver, and red, each corresponding to the four extreme Yin Lands of Heaven and Earth Xuanhuang.

In addition, Situ Nan also mentioned that even different extreme yin places are also divided into four levels: ordinary, excellent, Shen Yin, and absolute yin.

Each level is divided into 10 grades.

Generally speaking, reaching the ordinary third rank or above can be used to cultivate the Huangquan Ascension Technique, and reaching the ordinary eighth rank or above can speed up the cultivation speed.

After the ball of light appeared, it suddenly emitted a strong red light, and the red light became brighter and brighter, and finally flashed five times in a row.

Wang Lin touched his chin, his eyes flashed, he knew that the flickering five times meant that the quality of this Yellow Yin Land was an ordinary five grade.

After a little silence, he controlled the ball of light without saying a word, and walked towards the ruins. The cold aura around him became stronger and stronger as Wang Lin walked in, and finally he even had a feeling of walking in the water, this breath was too heavy, and he felt suffocated just a few hundred meters.

At this time, the ball of light also became brighter and brighter as Wang Lin walked, reaching the ordinary eighth grade.

Wang Lin didn't stop, continued to move forward, walked a few hundred meters, and came to the wreckage where the stone bead was, he couldn't move forward anymore, the cold qi burrowed into his body, the blood vessels all over his body began to sting, and the spiritual power was even more uncontrollable.

At this time, the red ball slammed, split into two, and flickered at the same time, Wang Lin's eyes flashed, he knew that this meant that the quality of this place had reached the best grade.

According to Wang Lin's search for the ruins during the day, he knew that the ruins were huge, and his current location was probably less than one ten-thousandth.

And as you go deeper, the colder it becomes.

"This is definitely the best place to cultivate!" Wang Lin slowly stepped back and stopped at the position of the ordinary fifth grade before.

This location is the most suitable location for Wang Lin after analysis, and the demand for the extreme yin land must be gradual, which is the focus of Situ Nan's repeated instructions before he fell asleep.

Wang Lin pondered a little, sat cross-legged on the ground, closed his eyes and pondered, and his mind echoed in his mind the Huangquan Ascension Decision explained in detail by Situ Nan.

This Yellow Spring Ascension Aperture is divided into nine layers, and every three layers of cultivation can condense a cold pill in the body, once all the nine layers are cultivated, the three cold pills will merge with each other, and there is a certain chance of climbing directly to the knot pill stage.

This was the biggest reason why Wang Lin made up his mind to cultivate the Huangquan Ascension Technique, and it was also the most suitable and fast one of the cultivation methods that Situ Nan knew.

Of course, there are also faster ones, such as taking the pill**, but capturing a master of the Dan period alive is really a suicide for Wang Lin at present.

The so-called Chong is a process that must be experienced in the cultivation of this exercise, and there are three major acupuncture points in the Huangquan Ascension Acupoint, which are the three acupuncture points of Dantian, Qi Hai, and Ancestral Aperture.

These three acupuncture points, at the moment of breaking through, will condense into a cold pill. As soon as the cold pill appears, the spiritual power in the body will immediately transform into the power of yin and cold.

As for the success rate of this punch, it has a lot to do with the quality of the Extreme Yin Land.

Time passed quickly, and when he opened his eyes again, the sky was getting brighter, and the cold air around him quickly dissipated, and the moment the sun rose, the cold breath was gone.

Wang Lin stood up, since he had decided to cultivate here, he wanted to find a place to live, he looked around, and the ultimate goal was a collapsed house not far from here.

With a wave of his right hand, all the collapsed wreckage, rubble and other objects floated up and scattered around, clearing a small open space.

After doing everything, Wang Lin sat quietly cross-legged in the open space, took out a thread-bound book from the storage bag, concentrated his breath, and looked through it carefully.

This book is a detailed explanation of the formation he exchanged for the Zhongpin Spirit Stone in Fujijia City two years ago.

At that time, he took a brief look and found that it depicted several formations in detail, and it was equipped with formation diagrams, and the introduction of various operations and furnishings was extremely comprehensive.

After memorizing all the contents inside, Wang Lin closed his eyes and pondered, waving his hands from time to time, unconsciously drawing something.

The time of the day passed quickly, and at dusk, Wang Lin sighed, opened his eyes, and muttered to himself: "This formation is broad and profound, even if it is described in this booklet some very simple small formations, it took me a day to barely understand a thing or two, especially some of the derivation techniques in it, pay attention to the power of calculation, the more you look back, the more difficult it becomes." ”

In desperation, he didn't think about it, but completely followed some of the formations inside, groped for it, grabbed the stones with gravitational magic, and placed them outside the room as required.

Like a gourd drawing, a formation called a small maze was finally put out.

This formation is too rough, too simple, not even the most basic town flag, looking at the scattered stones outside the room, Wang Lin smiled bitterly, carefully compared with the formation map, and adjusted a little, finally made it the same as the formation map requirement.

Wang Lin took a deep breath, pinched the magic trick with both hands as required, and quickly pointed at it, and suddenly a mist appeared silently, surrounding him.

Wang Lin looked at the mist and smiled bitterly, secretly saying that this formation was more than enough to trap some mortals, but for immortal cultivators, it was useless and could not achieve the purpose of protecting the Dharma.

After a little silence, Wang Lin muttered to himself: "If one formation is not useful, I will put two, and if it really doesn't work, I will ask all the formation diagrams in the booklet to be put out, so that it will more or less play a role." ”

Thinking of this, Wang Lin's gravitational technique was used again, controlling the surrounding stones, and after several formations in a row, night fell again.

Wang Lin sat cross-legged on the open ground, and at the moment when the cold air rose, he suddenly dropped his hands on his knees, concentrating. His exhalation is in the form of one long and five short. The so-called long one means that the inhalation time is long, and as for the short five, it means that the exhalation time is only one-fifth of the inhalation. Use the fastest speed to inhale the cold qi around you.

Strictly speaking, this was the first time he had been exposed to the outside world since he seized the foundation, and in the previous two years, he had absorbed all the spiritual energy liquid underground and digested it internally.

This cold aura is actually the same as the aura, Wang Lin has been breathing in the aura for many years, and he is naturally familiar with it, but he immediately noticed the difference, when he exhaled the aura in the past, there seemed to be a membrane outside the body, hindering the aura, and the speed of the aura entering the body was not only slow, but also only a part of it could be absorbed after entering the body, and most of it would disappear with the aura.

But now it was different, the film seemed to have disappeared, and the cold aura came overwhelmingly the moment he just breathed it out. And as if he had changed his body, the cold qi that poured into his body actually absorbed more than half, which was completely different from before.

Wang Lin pondered this situation for a while, and had three answers in his heart, first, the cold qi and the aura were different, which was more suitable for him to breathe. Second, after the foundation building period, the exhalation will naturally be much faster than that of the condensation period. Third, after absorbing some of Teng Li's spiritual roots, his talent has improved a lot.

As for which answer was correct, Wang Lin did not delve into it, but immersed himself in vomiting.

At the beginning, Wang Lin was very uncomfortable, because the attribute of this cold qi was cold, and after inhaling it into his body, it immediately dispersed and drilled into the internal organs of his body, and the kind of cold that emanated from the inside to the outside made his body tremble. This feeling is diametrically opposed to absorbing the aura into the body, one is the warmth and comfort of the body, and the other is the freezing like entering an ice cellar.

As the cold breath was inhaled more and more, Wang Lin's hands and feet were cold, and the blood flow speed in his body gradually became viscous, and finally even his heartbeat slowed down.

His eyebrows, hair, and hair all over his body slowly appeared frosty, and a cold aura penetrated from his body, blending perfectly with the surroundings.

Time flies by, when the sun rises, the cold dissipates, Wang Lin's eyelids tremble, he opened his eyes, he exhaled a deep breath of white air, after a night of breathing, a small air mass faintly appeared in his abdomen, this air mass slowly rotated silently, and a trace of cold air gradually dispersed.

The spiritual power in the body does not have any rejection of this air mass, and there is no intermingling of the unrelated ones.
