The aura giant scanned the surroundings and found no other immortal cultivators, so it dissipated into the air.

Zhang Hao fell from the sky, and after standing still, he exhaled a breath to calm the emotions in his heart.

Zhang Hao walked towards a puddle of meat mud, and should be able to find some loot.

More than fifty spirit stones, eight bottles of elixir, six talismans, and fragments of bronze bell magic vessels in one place.

It's just that the spirit stone and the pill were smashed, the talisman and the flesh and blood were stuck together, and the fragments of the magic weapon couldn't be put together.

Zhang Hao was too lazy to clean up, and left here quickly.

After encountering more than a dozen waves of trouble along the way, Zhang Hao ran as soon as he could, and turned around and killed the other party if he couldn't run!

Fortunately, I didn't meet a monk above the Jindan stage.

More than two months later, Zhang Hao came to the entrance of the secret realm.

The entrance to the secret realm is no longer guarded by the disciples of the three major sects, and all the people who come in and out are some loose cultivators, and they look very calm.

Zhang Hao observed it for a while and then walked in.

The large array near the entrance has been cracked by the three major sects, and a large area has been vacated, and I don't know when wooden houses have been built and developed into a fang market.

Zhang Hao bypassed Fang City, entered the large array in front of him from the side, and walked towards the palace.

The large arrays that shrouded the palace were still arranged by Zhang Hao using the nine-story array tower, and some of the large arrays continued to play a role because of the abundant spiritual energy in the secret realm, which was enough to resist the entry of immortal cultivators outside.

Walking to the side of the palace, Zhang Hao dug up the dragon balls.

Holding the Dragon Ball, Zhang Hao could feel the endless aura inside, which was just used to build the foundation!

Back in the palace, Zhang Hao suddenly remembered that there were still many 10,000-year-old elixirs here, which might have an effect on Lord Yun's recovery.

Zhang Hao immediately walked to the back of the hall and took out the Yunpa Immortal Weapon.

"Lord Yun, can you see if these 10,000-year-old elixirs are useful?" Zhang Hao shouted at the Yunpa Immortal Weapon.

The Yunpa Immortal Weapon flew out of Zhang Hao's hand and flew into the prohibition of these 10,000-year-old elixirs, sending out a suction force to absorb one 10,000-year-old elixir......

As long as he can wake up Lord Yun, Zhang Hao is also willing to give the elixir of ten thousand years, because it is better to give it to Lord Yun than to cheapen others!

These prohibitions were all set by the immortal cultivators in the refining period! If you want to break it, you don't know how long you want to cultivate.

Soon, all the 10,000-year-old elixirs were absorbed by the Yunpa Immortal Weapon!

In the end, the Yunpa Immortal Weapon flew back from the prohibition wrapped in a 10,000-year-old spirit fruit.

Zhang Hao heard Lord Yun's voice: "This is the Ten Thousand Year Green Wood Spirit Fruit, which can help you build a foundation." ”

The voice is back to normal, and it is no longer so weak.

Zhang Hao took the 10,000-year-old green wood spirit fruit, which looked very much like a green apple, but it was much smaller than a green apple, and it could be eaten in two bites at most.

Taking advantage of Lord Yun's awakening, Zhang Hao hurriedly asked, "Lord Yun, what is the foundation of the Great Dao?"

Since cultivating the Qi part of the "Haotian Dao Sutra Part I", Zhang Hao has been studying the foundation building part over and over again at the same time, and the most mentioned one is "Great Dao Foundation!"

In the past, Zhang Hao patronized and compared the advantages and disadvantages of various foundation building exercises, and did not deduct words to study.

"Great Dao Foundation" not only appears many times in the "Haotian Dao Sutra Part I" exercises, but also appears many times in other foundation building exercises.

Since the "Great Dao Foundation" has appeared many times in all the foundation building exercises, Zhang Hao naturally noticed it.

But what does it mean to be "the foundation of the Great Dao"?

Zhang Hao guessed a lot of meanings, but he wasn't very sure, he wanted to ask last time, but unfortunately he was a step too late.

"The foundation of the Great Dao, you can take it apart and understand, what is the Great Dao, what is the foundation?" reminded Master Yun.

Zhang Hao thought for a while, and then replied: "The Great Dao is the great truth, it can be the great truth of one person, it can also be the great truth of everything, and it can even be the great truth of heaven, earth and the universe. As for the great truth of immortal cultivators, I can't figure out what it is?"

Master Yun laughed, "It's the first time I've heard someone understand the Great Dao like this!"

"Isn't that right?" Zhang Hao asked.

"There is no right or wrong in the Great Dao!" Lord Yun said softly, "If you want me to answer what the Great Dao is, I will tell you, 'One, the Dao!' The Great Dao existed before heaven and earth!"

One, the way!

It's as simple as that?

Zhang Hao felt that he had heard this somewhere, but he couldn't remember it for a while.

"To exist before heaven and earth is for chaos. You just need to understand that the 'Great Dao' is in the chaos!" Lord Yun said again.

Zhang Hao nodded, and then asked excitedly, "That Chaos Bead is really a treasure, isn't it used by the Earth Demon to bluff me?"

"The Earth Demon didn't bluff you, the Chaos Bead is indeed a treasure, and it will be very helpful to your foundation building success and cultivation during the foundation building period!" Lord Yun replied affirmatively.

"That foundation is equivalent to building a house and laying a foundation, and the stronger the foundation, the higher the level you will reach in the future. Zhang Hao then asked.

Master Yun said directly: "The foundation is your immortal root! The realm that you can reach by cultivation is determined by your immortal root! It's like a miscellaneous immortal root can't build a foundation successfully, and can only die of old age in the Qi cultivation period. ”

Zhang Hao was stunned for a moment, and then asked unconvinced: "Can't you change it through the efforts of the day after tomorrow?"

Lord Yun said lightly: "You can improve your immortal root the day after tomorrow, so as to change the realm you can reach!

Zhang Hao understood that the quality of the immortal root determined the highest realm that an immortal cultivator could achieve!

Miscellaneous immortal roots can only be in the Qi cultivation period, and it is impossible to cultivate to the foundation building period!

And if you want to improve the quality of the fairy root, Zhang Hao feels that it is really difficult!

"That's why I'm looking forward to you building a successful foundation, so as to break the iron laws of the immortal cultivation world for thousands of years!" Lord Yun encouraged: "Don't disappoint me, you must work hard to build a foundation!"

Master Yun smiled, "Actually, you don't have to worry about what the foundation of the Great Dao means, just prepare to build the foundation step by step." If the foundation is successful, you don't need to know. If the foundation has failed, there is no need to know. ”

Zhang Hao put aside the issue of the foundation of the Great Dao, "Then I will restore the aura first, and then start building the foundation." ”

"Good!" replied Master Yun.

"Don't you have any instructions?" Zhang Hao asked again.

"No!" Master Yun said, "You've been preparing for so many years, what are you still hesitating about?"

Zhang Hao said in a low voice: "Aren't I worried about the failure of foundation building?"

"There's nothing to worry about! I'll watch you build the foundation and guide you at all times. Lord Yun reassured.

Zhang Hao smiled self-deprecatingly, he survived the college entrance examination that decided his life in his previous life, and he was afraid of the little foundation!

Zhang Hao sat down cross-legged, holding the dragon ball to absorb the aura inside to restore the consumption of the "Giant Spirit Technique" before using it.

The spiritual energy consumption in the body was all recovered, Zhang Hao did not stop, and directly began to build the foundation!

There are a total of 7,680 cyclones in the Upper Dantian, the Middle Dantian, the Lower Dantian, the Twelve Positive Meridians, the Eight Veins of the Qi Sutra, the Twelve Sutras, and the Twelve Meridians, all of which must be integrated into the immortal roots!

Lord Yun immediately pointed out:

"Step 1: Follow the foundation building method of the "Haotian Dao Sutra", and use the spiritual energy in the body to open the immortal root!"

"Step 2: Use the fingering method of sealing the veins recorded in the "Haotian Sect's Twelve Layers of Qi Cultivation Extension Exercises" to seal the upper dantian, the middle dantian, the eight veins of the Qi Sutra, the twelve meridians and the twelve meridians. ”

"Step 3: Absorb the aura in the Dragon Ball, start from the lower dantian and the twelve canons, and squeeze the cyclone to merge into the immortal root!"

With Master Yun's clear guidance, Zhang Hao knew what to do.

For the foundation-building part of the "Haotian Dao Sutra Part 1", Zhang Hao has already studied it many times and understands how to operate the aura in the body to open the immortal root.

The immortal root is a section of roots, one end is thin, the other is thick, the thin end is connected to the Qihai Dantian, and the thick end has a fracture that grows and heals.

The so-called opening of the fairy root refers to opening the fracture of hyperplasia and healing, giving the cyclone an easy entrance to integrate.

At the same time, after the fairy root fracture is opened, a suction force will be emitted, and the sucking cyclone will enter.

It's just that this suction force is too small to suck the cyclone at all, so it needs to be squeezed.

Soon, Zhang Hao opened the immortal root.

Then I went to familiarize myself with the meridian channels that can seal the upper dantian, the middle dantian, the eight veins of the Qi meridian, the twelve meridians and the twelve meridian tendons, and then find the correct position and seal them one by one with the fingering method of sealing the veins.

Zhang Hao was already familiar with the fingering method of sealing the veins, and he used it when he opened up the upper dantian.
