There is no sun and moon in the cultivation in the cave, and the reversal of the universe needs to build a foundation.

Wu Yan, who had completely fallen into a state of madness, took five Tsukidan pills in succession in three months!

His body had now accumulated a thick layer of black-gray membranous fishy substance, but he was not even interested in looking at it.

Five Tsukidan pills were taken successively. Wu Yan found that he still didn't succeed in building the foundation!

Wu Yan felt like he was about to collapse.

In his body, a large amount of medicinal power was accumulated before he had time to refine it, and these scattered medicinal powers in his body constantly washed away the impurities in his body, and automatically carried out the act of washing the marrow and changing the muscles of his body.

However, he did not care about these things in the slightest. Soon after taking the fifth Tsukidan, Wu Yan looked inside his body again.

This time, he finally discovered the abnormal change in the spiritual root!

He found that his spiritual root had undergone an unprecedented change!

When he took the fourth Tsukidan, when he looked inside, he found that the five spirit roots were all condensed as essence, and there was even a faint tendency to merge.

The taking of the fifth Tsukidan completely intensified this fusion.

After looking inside, he found that his spiritual root had turned into an unknown spiritual root with two attributes, black and white!

He hadn't even heard of this kind of spiritual root. However, the next changes in those two spirit roots dispelled a lot of his doubts. It even made him completely excited!

Using a special spirit stone to detect the spirit root, he tested his spirit root attributes, and something happened that made Wu Yan stunned.

He found that his spiritual root attribute turned out to be a random combination of five attributes.

Each time it is tested, there will be two combinations of spirit roots with different attributes. There is only one possibility for this strange state.

He became a special Alien Root Monk.

Because, in the world of cultivating immortals, there are many kinds of attributes of alien spirit roots, among which there is one of the most unlikely special alien spirit roots, called yin and yang attribute alien spirit roots. This kind of Yin and Yang attribute alien spirit root cultivator can practice any attribute exercises, even if he takes pills, there is no limit.

However, the Yin and Yang Alien Spirit Root, in the world of cultivating immortals, is very special and very rare, it is said that in history, in the entire human cultivation world, there are only two or three people in tens of thousands of years.

This kind of yin and yang attribute alien spirit root is special in that it is special, and outsiders will never be able to see it. Because, when outsiders use special exercises to check, they can only see that the monk with this yin and yang attribute alien spirit root is a true spirit root monk with any two random combinations of five element attributes.

Therefore, this yin and yang attribute of the alien spirit root is also known as the hidden spirit root, and only the monks who have this hidden spirit root attribute can know what kind of attribute they are.

Fortunately, Wu Yan likes to consult classics very much, otherwise, he really can't figure out what is going on with his own attribute.

Knowing that he had actually taken five Five Elements Attribute Zhuji Dan and turned into a Hidden Spirit Root Attribute, Wu Yan was so excited that he couldn't calm down and cultivate for several days.

Although he failed to build a foundation after taking five Tsukidan pills in a row, Wu Yan was still excited and couldn't calm down.

He didn't have to worry about not being able to build a foundation at all.

The monks of the alien spirit root attribute have basically no bottleneck when building the foundation and forming the pill. He only needs to absorb and refine the large amount of medicinal power trapped in his body now, and if nothing else, he can build a successful foundation!

After several days of excitement, Wu Yan finally calmed down.

On this day, he adjusted his emotions and state, sat down on the futon in the Earth Fire Alchemy Room, swallowed the next Bigu Pill, and began to retreat and meditate, refining the medicinal power of the five Zhuji Pills accumulated in his body.

......

Time passed day by day as Wu Yan refined the medicinal power in his body.

One month, two months, three months......

Half a year later.

On this day, Wu Yan's whole body suddenly exuded a huge momentum and coercion, and the temperament of the whole person changed dramatically at this moment!

He didn't even open his eyes, and under the unfolding of his divine sense, he instantly "saw" all the qiē within a radius of ten miles of the entire Five Elements Peak in his mind!

Yin and yang, the universe is reversed!

At this moment, Wu Yan even had a mysterious feeling that he was completely in control of his own destiny!

However, this feeling only lasted for a few breaths.

Wu Yan jumped up from the futon in surprise, and the whole person rolled on the ground again, laughing madly, venting the excitement and excitement in his heart!

On the road to cultivating immortals, the foundation building period is a hurdle, and when it passes, it will enter a new world, and it will not pass, and it will be insulated from the avenue, and it will never want to escape from the mortal world, and the red dust will be reincarnated.

However, before he could be happy for a moment, the meridians all over his body suddenly became hot, and he sat down in a hurry.

In the past six months of meditation and cultivation, he has completely figured out a qiē.

He took five Tsukidan, and at first he absorbed only the special substance in Tsukidan that changed the properties of the spiritual root, but the medicinal power of Tsukidan was not absorbed and refined by him nine times out of ten.

The medicinal power contained in the five Tsukidans is amazing. In particular, these five Zhuji Pills were still refined with the inner pills of five different single attribute demon beasts, and the demon yuan power transformed by the five demon pills was even much more powerful than the medicinal power of those twelve materials.

This time, it took half a year, and he only absorbed forty percent of the medicinal power, and he succeeded in building the foundation in one fell swoop!

There are also sixty percent of the medicinal power scattered all over the body, if you don't quickly absorb and refine, it will not be a good thing to stay in the body for a long time.

After hurriedly cleaning up, Wu Yan pondered.

He is now a monk in the foundation building period, and it is obviously inappropriate to practice the True Technique of Qi Cultivation again, and it is impossible for him to absorb medicinal power.

Now he has to practice the exercises of the foundation building period.

Wu Yan hurriedly found out the exercises of the foundation building period of the "Five Elements Sword Codex" left by Mo Ao from the storage bag. Mo Ao once told him that the "Five Elements Sword Codex" is divided into five stages, and each stage corresponds to a realm, which are Qi Refining, Foundation Building, Jin Dan, Yuan Ying and Huashen. And in each stage, there are three layers, and there are a total of fifteen layers in the complete set of "Five Elements Sword Codex".

The True Technique of Qi Cultivation is actually the first three layers of the Five Elements Sword Canon, but these three layers are subdivided into twelve small realm levels.

In other words, he has now practiced the first three layers of the Five Elements Sword Codex. Now he was about to start cultivating the Fourth Layer of the Five Elements Sword Codex.

He even has some expectations now, after practicing to the fourth layer, he will learn the majesty of the small divine powers "Imperial Sword Technique" and "Body Protection Sword Shield".

After checking the fourth, fifth, and sixth layer of the "Five Elements Sword Codex" that Mo Ao had left him with his divine sense, Wu Yan began to concentrate on cultivating and absorbing the residual medicinal power in his body according to the method of the fourth layer.

This cultivation made Wu Yanshuang almost scream.

The change in the spiritual root's qualifications, without deliberately taking pills and absorbing the earth's leyline aura, can be smoothly cultivated quickly, which really made him feel the rapid pleasure of those geniuses' cultivation.

The fourth-layer exercises, a simple cycle, made him feel an unprecedented sense of pleasure when his mana skyrocketed, this feeling was really amazing!

I really want to experience this feeling every day.
