Wang Lin suddenly had a bold guess in his mind. One day, many people were sitting at the dinner table, and suddenly disaster came. Without any awareness, the entire city turned into a dead ruin.

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

"From the size of this ruin, I'm afraid the population is less than tens of millions, and the place with tens of millions of dead people should be the best yellow-like extreme yin place among the four places of the world, the world, the world."

Situ Nan once explained in detail the place of the extreme yin during Wang Lin's retreat. The place of the extreme yin is divided into four types, namely the heavenly yin, the earthly yin, the Xuanyin, and the Huangyin.

The simplest place in Huangyin is. The place where a large number of creatures die is the place in Huangyin. The more people die, the better the place in Huangyin.

The place of Xuanyin is somewhat difficult, and most of it only appears in extremely cold places.

Earth Yin is even more difficult, and it takes a great opportunity to encounter it. After all, the so-called Earth Yin is the breath emitted from the underground abyss.

As for the lunar sky, it is basically impossible to appear, because to form a lunar sky, it is necessary to have both the lunar sky, Xuan and Huang, which will produce a wonderful transformation and turn into a lunar sky.

The higher the quality of the extreme Yin land, the greater the benefit to practitioners.

Wang Lin immediately made a gesture with his right hand and muttered something in his mouth. Suddenly, a trace of red light spots condensed in front of him, and finally formed a red light ball.

This is a spell specially used to test the quality of the extreme yin land. According to the color of the light ball, there are four kinds of light, namely purple, blue, silver, and red, each corresponding to the four extreme yin lands of heaven and earth.

In addition, Situ Nan once mentioned that even different extreme yin places are divided into four levels: ordinary, superior, sunny and absolute yin.

Each level is divided into ten grades.

Generally speaking, if you reach the third level or above, you can be used to practice the Huangquan Ascension Skill, and if you reach the eighth level or above, you can speed up your cultivation speed.

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

Wang Lin touched his chin and his eyes flashed. He knew that the five flashes meant that the quality of this Huangyin land was ordinary fifth grade.

After pondering for a little while, he controlled the light ball and walked into the ruins without saying a word. The cold and cold aura around him became stronger and stronger as Wang Lin walked in. Finally, he even felt like he was walking in the water. The aura was too heavy, and he felt a suffocation after walking a few hundred feet away.

At this time, the light ball became brighter and brighter as Wang Lin moved, reaching the eighth grade.

Wang Lin did not stop and continued to move forward. He walked a few hundred feet away and came to the wreckage where the stone bead was. He could no longer move forward. The cold and cold air penetrated into his body, and the blood vessels in his body began to sting, and there were signs of uncontrollable spiritual power.

At this time, the red ball thuded, split into two, and flashed at the same time. Wang Lin's eyes flashed. He knew that this meant that the quality here reached the best grade.

According to the search for the ruins by Bai Tian Wang Lin, he knew that the ruins were extremely large, and his current location was probably less than one ten thousand.

And as you go deeper, the stronger the yin and cold air becomes.

"This is definitely the best place to practice!" Wang Lin slowly retreated and stopped at the previous position of the fifth grade.

This location is the place that Wang Lin thought that his body was most suitable after analysis. Huangquan Ascension to the orifice must gradually improve the demand for the extremely yin place. This is the focus of Situ Nan's repeated instructions before he fell asleep.

Wang Lin pondered for a little while, sat cross-legged, closed his eyes and pondered, and his mind echoed in detail about the Huangquan Ascension Judgment that Situ Nan explained in detail.

The Huangquan Ascension Decision is divided into nine levels. Each three levels of practice can condense a cold pill in the body. Once the nine levels are all practiced, the three cold pills will merge with each other, and there is a certain chance that they will directly climb to the elixir stage.

This is the biggest reason why Wang Lin decided to practice the Huangquan Ascension Skill. It is also the most suitable practice technique that Situ Nan knows, and is currently the fastest one.

Of course, there are also faster ones, such as the method of seizing alchemy, but capturing a master of the alchemy stage alive is undoubtedly a suicide for Wang Lin at present.

The cold pill of the Huangquan Ascension Jue is completed by rushing to the orifice. The so-called rushing to the orifice is a process that must be gone through to practice this technique. There are three major acupoints of the Huangquan Ascension Jue, namely the three acupoints of the Dantian, Qihai, and Ancestral Orifice.

The cold pill will condense into these three acupoints at the moment they break through. When the cold pill appears, the spiritual power in the body will immediately change and become the power of yin and cold.

As for the success rate of this orifice, it has a lot to do with the quality of the extreme Yin land.

Time passed quickly. When he opened his eyes again, the sky gradually became brighter and the cold and cold air around him quickly dissipated. The moment the sun rose, the cold air disappeared.

Wang Lin stood up and since he decided to practice here, he wanted to create a place of residence. He looked around and finally aimed at a collapsed house not far from here.

With a wave of his right hand, the collapsed wreckage, gravel and other objects floated up and fell around, clearing out a small piece of open space.

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

This book is a detailed explanation of the formation he exchanged for medium-grade spirit stones in Tengjiacheng two years ago.

At that time, he took a brief look and found that several arrays were depicted in detail, equipped with array diagrams, and various operation arrangements were introduced in an extremely comprehensive manner.

After remembering all the contents inside, Wang Lin closed his eyes and pondered, waved his hands from time to time, drawing something without any sense.

The day passed quickly. At dusk, Wang Lin sighed, opened his eyes and murmured to himself: "This formation is profound and profound. Even if the booklet describes some very simple small formations, it took me a day to understand one or two, especially some of the derivative techniques inside, which pays attention to the power of calculation. The more you look at it, the more difficult it becomes."

In desperation, he stopped thinking about it, but followed some array diagrams inside completely, groping, while using gravity to grab the stones and put them outside the room as required.

As if he copied it, he finally formed a formation called Xiaomizhi.

The formation was too rough and too simple, and there was not even the minimum town flag. Looking at the chaotic stones outside the room, Wang Lin smiled bitterly, carefully compared the formation diagram, and adjusted it a little more, and finally it was exactly the same as the requirements of the formation diagram.

Wang Lin took a deep breath, pinched the magic formula as required with both hands, and pointed quickly, and a fog suddenly appeared silently and surrounded him.

Wang Lin looked at the fog and smiled bitterly, thinking that this formation would be more than enough to trap some mortals, but for those who practice immortals, it was useless and could not achieve the purpose of protecting the Dharma.

After pondering for a while, Wang Lin murmured to himself: "If one formation is not useful, I will just place two. If it really doesn't work, I will ask to put out all the array maps in the booklet. In this way, it will be more or less effective."

Thinking of this, Wang Lin used the gravitational technique again, controlling the surrounding stones, and then placing several array diagrams in succession, night fell again.

Wang Lin sat cross-legged in the open space. When the yin and cold air rose, he suddenly split his hands and concentrated his breathing. His breathing was in a way of five. The so-called long means that the breathing time is long, and as for the shortest five, it means that the exhalation time is only one-fifth of the breathing time. At the fastest speed, the yin and cold air around him is absorbed into his body.

Strictly speaking, this was his first external breathing after taking the foundation. In the past two years, he absorbed spiritual fluids underground and digested them internally.

This yin and cold energy is actually the same as spiritual energy. Wang Lin has been breathing in spiritual energy for many years and is naturally familiar with it. But immediately he noticed the difference. In the past, when he breathed in spiritual energy, there seemed to be a thin film outside his body, which hindered the breathing. The speed of spiritual energy entering the body was not only slow, but it could only absorb part of it after entering the body, and most of it would disappear with the breathing.

But it is different now. The film seems to have disappeared. The yin and cold air surged overwhelmed as soon as he breathed it. And he seemed to have changed his body, and the yin and cold air poured into his body was absorbed by half, completely different from before.

Wang Lin thought about this situation for a moment and had three answers in his heart. First, the yin and cold energy are different from spiritual energy, which is more suitable for him to breathe. Second, the breathing will naturally be much faster after the foundation-building stage than the Qi Condensation stage. Third, after absorbing some of Teng Li's spiritual roots, his talent has improved a lot.

As for which answer is correct, Wang Lin did not go into it, but was immersed in breathing.

At the beginning, Wang Lin was very uncomfortable because the cold and cold energy was cold. After sucking it into his body, he immediately scattered into his internal organs. The coldness emitted from the inside out made his body tremble. This feeling was completely opposite to absorbing spiritual energy into his body. One was the warm and comfortable body, and the other was the freezing like an ice cellar.

As the yin and cold breath was inhaled more and more, Wang Lin's hands and feet were cold, and the blood flow rate in his body gradually became sticky, and finally even his heartbeat became slower.

His eyebrows, hair, and hairs slowly appeared frosty, and a yin and cold air came out of his body, perfectly blending with the surroundings.

Time passed quickly. When the sun rose, the cold and cold dissipated. Wang Lin's eyelids trembled and he opened his eyes. He exhaled a deep breath of white air. After a night of breathing, a small air ball appeared faintly in his abdomen. The air ball slowly rotated silently, and a trace of cold air gradually dissipated.
