Hua Xia Jiu didn't know anything about these things, but this did not prevent Hua Xia Jiu from being grateful to the ghost. In his opinion, this information is knowledge, the knowledge that is directly used to transform into the realm of strength, the most precious knowledge in the world, and something that no amount of spirit stone treasures can buy.

After Huaxia Jiu's combing and selection, there are two exercises practiced in the Huadan Realm, one of which is the top extreme exercise "Netherworld Divine Skill" that has been passed down from generation to generation in the Netherworld, and the other is the "Netherworld Divine Technique" obtained by chance by the Netherworld's own coincidence.

It's just that the "Netherworld Divine Technique" is a fragment, only the upper half, which only includes the exercises practiced before the Dao realm, and the "Netherworld Divine Skill" is naturally complete, and you can also check the cultivation experience summarized by the predecessors of the Netherworld in the Hidden Scripture Pavilion of the Netherworld One Lineage over the past ten thousand years.

For this reason, the ghost itself was also promoted to the Dao realm, and changed the "Netherworld Divine Skill", but fortunately, the attributes of these two exercises are similar, so the ghost was able to successfully change his own exercises to "Netherworld Divine Skill" with the help of the Netherworld real person.

After carefully reading the contents of the two divine skills, Hua Xia Jiu began to ponder and choose. The ghost did not help him choose which exercise, but after explaining the relevant situation, it was up to Hua Xia Jiu to decide. Whether it is what the ghost said, or Hua Xia Jiu's own judgment, "The Secret of the Underworld" is extremely profound and subtle, and even faintly more profound than "The Secret of the Netherworld".

On the way of cultivation, most of the exercises practiced during the period of condensing the spirit realm are similar, but because the speed at which they can absorb the spiritual energy is fast or slow, so there is a grade division. However, above the Hua Dan Realm, the cultivation speed that can be reflected and the power of the magic spell that can be manifested are extremely different.

Moreover, it is relatively easy for a monk to transfer to the cultivation method during the condensation realm, but once the Dan is transformed, if he wants to change the cultivation method, unless the attributes are the same and there are some permits, it is difficult to ascend to the sky. This was also the reason why Hua Xia Jiu had already cultivated to the consummation of the Spirit Condensation Realm a few months ago, and had not always considered the Transformation Pill. And this is also the reason why the three sects and nine sects, such as the Purple Shadow Sect, recruit disciples and only recruit low-level monks under the Huadan Realm.

Hua Xia Jiu didn't think about it for long, he decided to change the "Netherworld Divine Skill", even if the "Netherworld Divine Technique" seemed to be more subtle and profound than the "Netherworld Divine Skill", but without the complete exercise, he could only regret giving up.

After making a decision, Hua Xia Jiu made up his mind and directly closed his eyes and began to cultivate.

To transfer the cultivation method, the first step is to follow the mental method essentials of the "Netherworld Divine Skill", and run the true yuan in the True Yuan Lake one by one in the specific operation meridians of the "Netherworld Divine Skill" for nine Great Zhou Heavens, and then the true element nature can be transformed into the true element of the "Netherworld Divine Skill" unique Yin and cold attributes.

It didn't take much time, Hua Xia Jiu had fully comprehended the essentials of the "Netherworld Divine Skill", and then entered a calm and waveless state of concentration.

Huaxia Nine Hearts sank into the dantian, controlled and guided the true element, and began to operate in a specific meridian, this part of the true element is the limit that can be accommodated with the breadth and strength of the meridians without damaging the meridians, but it is less than one thousandth of the true yuan lake.

I don't know if it's because the soul form is much stronger than in the same realm, the Huaxia Nine Mind God guides the true yuan to run in the meridians, which is much faster than that of the monks in the same realm.

Such a speed is already considered fast, but looking at this true yuan, which only accounts for one thousandth of the total number and has transformed from white to gray, Hua Xia Jiu couldn't help frowning.

According to the content of "Netherworld Divine Skill", the true yuan cultivated is divided into three qualities: upper, middle and lower, of which gray is the lower grade, black is the middle grade, and purple is the upper grade. The lower the quality, the smaller the density of the true element, on the contrary, the higher the quality, the more refined the true element, the greater the density, and the greater the power.

At this time, the true element transformed was the lowest quality gray, which couldn't help but disappoint the nine major Huaxia people.

Hua Xia Jiu frowned and groaned, searching for information about the transformation of the exercises in his mind, and making calculations.

After the half-burnt incense time, Hua Xia Jiu's face showed a look of understanding.

When transferring exercises, if the attributes of the two exercises do not conflict, it is usually only necessary to let the original true element run nine times in the specific meridian of the practice to be transferred, and then it can be transformed. But if there is a conflict of attributes, it is not just nine, it may take eighteen, or even thirty-six or more.

After finding the reason, Huaxia Jiuxin Shen sank into the dantian meridians again, controlling the true yuan that had turned gray in the thousandth of it just now, and continued to start operating in the meridians.

It was another nine breaths of time, and this part of the true element had once again been running in the meridians for nine weeks, and the color of the thousandth true element had deepened significantly, but it was only between gray and black, and it still hadn't transformed into black, let alone purple.

Seeing this, Huaxia Jiu did not give up, did not hesitate, and directly controlled this thousandth true yuan to run again.

It wasn't until after the eighteenth breath time that this part of the true yuan ran again for eighteen weeks, plus the original two nine weeks, it was already thirty-six weeks, and the thousandth of the true yuan was completely transformed into black and became a medium grade.

Most of the disciples of the Inner Sect of the Netherworld Mountain were this middle-grade black true yuan, but Hua Xia Jiu was still not satisfied. Without hesitation, he once again controlled the thousandth of the black true element and began to operate.

It was another thirty-six days, and this part of the True Yuan was obviously much darker, but there was not the slightest sign of turning purple.

Huaxia Jiu did not give up and continued to control the operation of Zhenyuan.

After such a stick of incense, Hua Xia Jiu's face was slightly pale, and his mind was consumed too much, and the thousandth of a black true yuan had been running for nearly a thousand weeks, and the black and rich had reached the extreme, but it had never been transformed into purple.

Although Hua Xia Jiu was extremely unwilling in his heart, he had to stop his cultivation and frown and think about it.

"It seems that it is impossible to transform the true element in the body into a high-grade purple in one fell swoop, and even if it can really be transformed into purple, at this rate, it will be the year of the monkey. Thinking about the beginning, it only took him less than a month to cultivate from no cultivation to the consummation of the Spirit Condensation Realm. If this is the case, it is really better to break the True Yuan Lake, cast all the True Yuan of the "Tianyi Forging Divine Technique" in it, and then re-cultivate the "Netherworld Divine Skill". It's just that in this way, it's a pity that these existing true elements are also the result of hard cultivation. After half a ring, Hua Xia Jiu's face was a little ugly and muttered.

Just when Hua Xia Jiu wanted to dissipate the true element of the "Tianyi Forging Divine Formula", suddenly a flash of inspiration flashed in his mind, and he remembered the cultivation method of the "Immortal Divine Formula".

"Absorb the spirit into the body, divide it into two, rise and sink, enter the dantian to achieve the true yuan lake, turn into the true yuan dan, cultivate the true spirit out of the body, and perceive the avenue of heaven and earth. The second ascension of the soul sea, turned into a cornerstone, cultivated the altar of the god of the underworld, and achieved the position of the true god. ”

There is a great difference between the cultivation method of "Immortal Divine Technique" and other cultivation exercises, that is, the absorbed spiritual energy is transformed into the true element in the body, except for half of the true yuan into the dantian true yuan lake, the other half of the true yuan is through inexplicable channels, flowing into the most mysterious and strange soul sea in the human body.

The second watch will be sent, and there will be a watch in the evening. Ask for collection, ask for red tickets, ask for praise――――
