"Now you don't need to know what the Natal Dao is, when you cultivate to the stage of transforming into a god, you will naturally understand!" Master Yun continued: "Thunder Spirit and Yin-Yang Fruit are both rare immortal things, and integrating Thunder Spirit into the Immortal Root is the Middle-grade Thunder Dao!

One is the middle grade, the other is the top grade, of course Zhang Hao will choose the top grade!

Master Yun understood what Zhang Hao was thinking, "Integrating the five elements of metal, wood, water, fire, and earth into the immortal root is the inferior Five Elements Dao, and you can exert the power of the Great Dao in the Transformation Period! This is your third choice!"

Zhang Hao wondered why Lord Yun mentioned the Five Elements Avenue again?

"After the Yuan Infant Period, it will be: the Transformation Period, the Refining Void Period, the Merge Period, the Mahayana Period, and the Tribulation Period, the Middle Grade Thunder Dao will not be able to exert the power of the Great Dao until the Merge Period! The Upper Grade Yin Yang Dao will not be able to exert the power of the Great Dao until the Tribulation Period!" Lord Yun said again.

Zhang Hao thought about it and understood why Lord Yun said so much!

The lower grade avenue can be used during the transformation period!

Zhongpin Avenue can only be used until the merger period!

Shangpin Avenue can only be used until the Tribulation Period!

The more advanced the Natal Dao, the higher the cultivation level to use!

So the question arises: do you want to be able to use the power of the Great Dao during the Transformation Period, or do you want a more advanced Natal Dao?

Zhang Hao is more inclined to choose the top-grade natal avenue!

Because good things who don't want!

Zhang Hao asked, "Do you think I can cultivate to the Tribulation Period?"

"No!" Master Yun replied directly.

This means that Zhang Hao and Shangpin Natal Avenue have no chance!

Zhang Hao asked again, "Do you think I can cultivate to the merge stage?"

"No!" Master Yun replied directly.

This means that Zhang Hao and Zhongpin Natal Avenue are also missing!

Zhang Hao asked, "Do you think I can cultivate to the stage of transforming into a god?"

Master Yun paused, but replied directly: "No!"

This means that Zhang Hao and the lower grade natal avenue are also missing!

Zhang Hao sighed and spread out his hands, "In that case, why do you bother to ask this question? I'm just a miscellaneous immortal root, and the Natal Dao is simply superfluous to me!"

Lord Yun was silent for a long time before he said, "The period of immortal root transformation is the best time to integrate into the Natal Dao, and you just have the Thunder Spirit and the Yin Yang Fruit at hand, both of which can be integrated into the Immortal Root as the Natal Dao. ”

After speaking, Master Yun whispered again: "I just don't want to see you miss such a good opportunity!"

Yes, what a chance! How many immortal cultivators can have immortal objects that can be integrated into the immortal root as a natal avenue when they build a foundation? And it's two!

"How do I feel that it is a complete waste for me to use?" Zhang Hao made a joke to ease the atmosphere.

Master Yun said softly: "Even in Haotian Sect, only the best immortal root disciples have such an opportunity! And it's only a low-grade Five Elements Immortal!"

"Then choose the Yin Yang Fruit!" Zhang Hao reluctantly smiled: "Give yourself a greater hope, so that you can have greater motivation to move forward!"

Lord Yun was stunned for a moment—if other immortal cultivators said this, Lord Yun would definitely mock him for not being able to do anything about himself! But when these words came out of Zhang Hao's mouth, Lord Yun believed it for some reason, and felt that it made sense.

"Okay, I'll help you!" Master Yun replied heavily.

I saw that the Yunpa Immortal Weapon flew out and wrapped the skin of the Yin Yang Fruit, and brought the skin of the Yin Yang Fruit into Zhang Hao's lower dantian.

The skin of the Yin-Yang Fruit was shrunk to a point by the Yunpa Immortal Weapon and thrown into the immortal root!

Zhang Hao suddenly felt the "joy" of the immortal root, and the life that was being nurtured suddenly became stronger!

"How about this thunder spirit for me?" Lord Yun said suddenly.

Zhang Hao hesitated for a moment, but still replied: "Okay! ”

Zhang Hao hesitated because the Earth Demon had said that the thunder spirit could be refined with spiritual power and endowed with spiritual power thunder attributes!

"Now you can practice the foundation building technique of the Haotian Dao Sutra, absorb the spiritual energy to refine the chaotic aura and generate the Haotian spiritual power, so as to use the Haotian spiritual power to catalyze the immortal root to accelerate the transformation. Master Yun pointed again.

Zhang Hao nodded, absorbing the aura in the Dragon Ball to cultivate the foundation building technique of the "Haotian Dao Sutra", to refine the wisps of chaotic aura in the Qi Sea Dantian, and generate a trace of Haotian spiritual power.

Master Yun continued:

"The aura of chaos contains everything, and most foundation building exercises can only refine a part of it, resulting in the generated spiritual power only having a part of the attributes, the most common being metallic, wood, water, fire, and earth. The utilization rate of this kind of foundation building technique on the chaotic aura is very low, it is completely a waste of chaotic aura, and the single-attribute spiritual power generated is also the weakest!"

"The more advanced the foundation building technique, the higher the utilization rate of the chaotic aura, and the more attributes the spiritual power generated. ”

"The foundation building technique of the Haotian Dao Sutra is the top, it can almost completely refine the chaotic aura, and the generated Haotian spiritual power almost integrates all the attributes, so it seems that there are no attributes. Therefore, Haotian's spiritual power can be used to catalyze the transformation of the immortal root!"

"It's just that it's the same as the difficulty of cultivation! If you want to refine more attributes from the chaotic aura, the more difficult it will be, so the foundation building technique of the Haotian Dao Sutra is also the most difficult to cultivate!"

......

At this moment, Zhang Hao no longer had the energy to listen to Master Yun's introduction to the foundation building exercises, because the cultivation of the foundation building exercises in the "Haotian Dao Sutra" was too difficult!

It is easy to refine and generate one attribute from the chaotic breath, but to refine and generate all attributes, it is equivalent to: 1+1+1+1+1+1+1+1+......=infinity!

Moreover, every time an attribute is refined and generated, it consumes aura, which means that it also consumes infinite aura!

Of course, infinity is just an exaggerated metaphor, which shows that the aura of chaos really contains everything, and it is really not easy to completely refine it!

The point is that after refining and generating all the attributes, they must be fused together, which is the final so-called Haotian spiritual power!

Therefore, Zhang Hao regretted choosing "Haotian Dao Sutra" as his foundation building method!

Even if you generate miscellaneous immortal roots, plus the immortal root +1 attribute, you are only equivalent to a five-grade immortal root, and it is still more compatible with the lowest foundation building technique!

In fact, Master Yun introduced so much to the foundation building exercises in order to persuade Zhang Hao to give up practicing the foundation building exercises of the "Haotian Dao Sutra".

It's just that Zhang Hao didn't listen to what Master Yun persuaded later!

Zhang Hao only listened to the first few sentences and knew: single-attribute spiritual power is the weakest, the foundation building technique of "Haotian Dao Sutra" is the top, Haotian spiritual power has almost all attributes, and Haotian spiritual power can be used to catalyze the transformation of immortal roots.

So when Zhang Hao wanted to give up, he would think of these words, so he took Lord Yun's persuasion as encouragement!

I can only blame Lord Yun, why didn't you just say that you gave up cultivating the foundation building technique of the "Haotian Dao Sutra"!

Maybe it was because he was too direct when he talked about the Natal Avenue before, and Lord Yun felt angry from Zhang Hao's question, so he was a lot more subtle this time.

As a result, Zhang Hao continued to practice the most difficult "Haotian Dao Sutra" foundation building exercises!

Lord Yun persuaded for a long time, but seeing that Zhang Hao was unmoved, he thought that Zhang Hao had great determination and ambition, so he didn't say more.

Anyway, everything that needs to be said has already been explained!

A trace of Haotian aura was cultivated by Zhang Hao......

Subsequently, this trace of Haotian aura was absorbed by the immortal root, speeding up the speed of the immortal root's transformation......

Until the fairy root finally gave birth to life!

The foundation is now complete!

Zhang Hao looked at the life in the immortal root, it was just a point, a very weak point, and it needed to absorb more nutrients to grow!

Zhang Hao stood up and exhaled a long breath, it has been almost a hundred years, and he has finally broken through to the foundation building period!

"How long do I live now?" Zhang Hao asked curiously.

"The lifespan of the Qi cultivation period will be increased by one hundred years! The lifespan of the foundation building period will be increased by two hundred years! The lifespan of the Jindan period will be increased by four hundred years! In this way, the lifespan of each realm breakthrough will be doubled!" Master Yun said lightly.

Zhang Hao calculated, "Then I still have three hundred years to live!"

"How many years does Lord Yun have to live?" Zhang Hao asked curiously.

"If the Yunpa Immortal Weapon is not completely destroyed, I will be able to survive forever, but ......" Lord Yun said halfway and stopped talking.

"What's just that?" Zhang Hao asked.
