This formation presents a four-place circle with the momentum of gossip, which is a profound defense and concealment formation, and the center of the formation is where Sun Meixiang is located. Sun Meixiang's skirt was surrounded by six lower-grade spirit stones, exuding a slight light, and her hands couldn't help but change her handprints, the light on her body seemed to be nothing, lined with bright light, and her delicate face was even more sacred.

This formation was arranged by Chu Hao, and now he is in the cave, and Sun Meixiang is outside to protect Chu Hao.

In the past three years, even with Chu Hao's help and the taking of the elixir, Sun Meixiang's cultivation has still progressed slowly, and only now has she barely touched the edge of the third-level foundation building, which is more than a point or two slower than the previous speed of cultivation advancement.

And even if Sun Meixiang has reached the third level of foundation building, compared to the monks of the same level, it is only the strength of spiritual power or the spell taught by Chu Hao is a cut higher, but if you really want to fight, whether it is experience or battle awareness, it is a situation of losing more and winning less, and in many cases, it is impossible to beat the other party.

At this moment, Sun Meixiang is Chu Hao's protector in the eyes of the array, precisely because Chu Hao is facing the biggest calamity he will encounter since he cultivated the truth.

-- Jindan period, Yudan!

Just as Tao Ranju's second sect master had predicted, Chu Hao really only took about three years to feel the Heaven and Earth Tribulation, this power from Heaven and Earth in his mind, and sent a message, that is, the Heavenly Tribulation was coming!

This message is something that almost every cultivator who has reached the Golden Pill stage will encounter, because this is a hurdle that a cultivator must go through in order to advance to the Golden Pill! The Six Great Tribulations are only the first step that the monks will face, the small six Heavenly Tribulations after the Dan!

Knot Dan means that there will be an extra inner Dan in the dantian that is closely related to your life!

In the cultivation realm, Jin Dan actually has two meanings, and includes two kinds of outer Dan and inner Dan. The so-called Outer Dan, as the name suggests, refers to the elixirs made by alchemists, such as the Yunling Pill refined by Chu Hao, the Zhuji Dan, the Condensing Star Frost Pill and even higher-level pills, etc., all belong to this list, while the Inner Dan is the cultivators who use the human body as a furnace, and then use the essence and qi in the body as medicine to smelt with the gods. In this way, the monks believe that the essence, qi, and spirit can be condensed and formed into a holy womb, and then they can be reborn into immortals.

In most senses, the theory of the golden pill is understood as the realm of the monk after the monk's marriage, and the inner pill has become the golden pill.

In the eyes of many mortals, they also regard the monks of the Jindan period as real immortals, because after reaching the Jindan stage, they are enough to fly to the heavens and the earth, move mountains and seas, and have the huge natural power of Jindan, which is very powerful.

Compared with the foundation building period, the Jindan period is more capable of cultivating the Gang Qi that belongs to the power of heaven and earth in addition to the Dan power, which is both a powerful liliang that belongs to its own exercises and spiritual roots.

Of course, there are also great risks. In addition to the probability of failure of the existence of Yudan, which has almost reached 1 in 10,000, there is also the ensuing Heavenly Tribulation!

Once the catastrophe cannot be passed, then even if the golden pill has just been formed, it will rupture with the heavenly tribulation, and the result of the failure of this tribulation will be seriously injured and the golden pill will be broken, and the heavy will be direct death.

Therefore, in this cruel cultivation realm, what is really terrifying and uncontrollable is the Heavenly Tribulation! The Six Great Heavenly Tribulations, the color of those who hear it, these liliang who come from the Heavenly Law and belong to the "Dao", even if the high-level monks suddenly look back, they will still have cold sweat and fright. It is rumored that even a true immortal in the immortal realm cannot control and control the Heavenly Tribulation!

And at this moment, Chu Hao, who was in the second heaven, was about to face the arrival of the first heavenly tribulation in his life. Before the Heavenly Tribulation came, the monks would have telepathy, Chu Hao felt the coming of the Heavenly Tribulation, and most of them may be in the near future!

It's just that although he has this feeling now, he doesn't know the exact time, nor does he know whether this is a mental tribulation or an external calamity, and the top priority at this moment is to complete his great cause of knotting Dan before the catastrophe comes, and reach the height of the Jindan period.

You must know that the foundation of cultivating immortals is extremely important, just like a building, the foundation is not thick enough, and it is impossible to build a higher and more stable foundation in the later stage. Whether you have a solid foundation in the early stage determines how much you will achieve in the future. Chu Hao had been suppressing himself in the early stage, and it was only in Zuihou that he broke through to the realm of the foundation building period, and for a monk with the Heavenly Spirit Root, his realm was too slow.

But Chu Hao was not in a hurry, because he knew that the investment in the early stage could be exchanged for the strength in the later stage!

In the Jindan stage, as long as he is in the second heaven and survives the heavenly tribulation, even if he is in front of the second sect master, it is just a joke! No one can predict how powerful the Heavenly Spirit Root cultivator who has reached the Jindan stage is, and this strength is absolutely earth-shattering and earth-shattering! After cultivating the Gang Qi, he is even more invincible at the same level!

The more others go to the back, the more difficult it is to cultivate, but Chu Hao is different, he has the "Hug Puzi Cultivation Skill" of the Jindan Period, and he also has his own Heavenly Spirit Root, and he is no different from the past when he advances.

In the cave, Chu Hao's eyes were closed, and his body exuded golden light, illuminating the entire cave as if it were day.

In the meridians in the body, the spiritual power flows over and over again under the operation of the body cultivation exercise, and each meridian and each vein has a warm feeling coming, like lava, and the spiritual power is slowly becoming viscous.

has not yet started to officially carry out the knotting, but Chu Hao has been sitting on this plate for a full thirteen days!

"The knot is only in an instant, but the early steps are extremely long and cumbersome, and if you are not careful, your efforts will be wasted. In the entire Nine Heavens, there are countless monks who have built the foundation of the Great Perfection, but there is only one in ten thousand who can really form a pill, and even fewer can successfully form a pill and survive the heavenly tribulation! Those people, great luck, great strength, and great wisdom, are indispensable!"

Recalling Chen Honghong's words in his mind, Chu Hao's spiritual platform was clear, and under his control, the spiritual power was beating rhythmically like a doppelganger.

"Hold on to the unity, the art of self-cultivation, care about heaven and earth, or save the heart, with essence, qi, and god as medicines, with the dantian body of the Ding furnace, from the furnace into the Ding, in the heaven and earth copper furnace, sintering the knot Dan ......"

Chu Hao recited the mantra in his mouth, and on the "Hug Puzi Cultivation Skill", he carefully and clearly recorded the places that need to be paid attention to when knotting, and at this moment, Chu Hao has recited this crucial mantra more than a hundred times, and in the whole thirteen days, that one piece will be engraved in Chu Hao's head.

Suddenly, Chu Hao felt his body fluttering, and an indescribable flow of heat penetrated his whole body, and the liliang hidden in the meridians, bone marrow, and muscles was released. Chu Hao hurriedly adhered to his original intention, letting this hot current flow towards every inch of his body, every time it was a Sunday, it seemed to be carrying out a marrow washing, muscles, meridians, and bone marrow were constantly being baptized.

Gradually, the meridians became wider and wider, Chu Hao's original meridians were like a stream, but now the meridians are like a surging river, and the river is turbulent, with a rushing momentum, expanding the meridians bigger and bigger.

Chu Hao didn't know what was going on, and he couldn't ask Chen Honghong at this moment, because Jiedan had to concentrate and couldn't be distracted at all, otherwise any fork might fail. And Chen Honghong didn't dare to open his mouth to disturb Chu Hao's thoughts at this time, the current situation, even if he had extremely deep knowledge and experience, could only rely on Chu Hao himself to get through.

The whole feeling was very good, the temperature of the whole body was rising, and the whole process lasted for more than two days, and the hot flow of the meridians that looked like lava suddenly began to become even hotter!

At first, Chu Hao was able to bear it, but when this heat flow converged towards the dantian over and over again, and the feeling was churning over and over again, it made him feel great pain! It was as if the entire dantian had turned into a furnace, and even the flame of the Fierce Phoenix Fire and the Purple Dragon Fire that had been suppressed under the dantian gradually became smaller, as if he had surrendered to this hot flow.

"The body is the furnace!"

After Chu Hao endured it for a long time, this thought suddenly flashed in his mind, and suddenly, he knew where this heat flow came from, it was the qi of heaven and earth that was transforming in his body, and what he needed at this time was the essence and spirit!

Just as alchemy requires the continuous addition of medicinal materials to control the fire, although Chu Hao has no way to control this fire, he can increase the medicinal materials and control the fire not so fiercely!

Thinking of this, Chu Hao immediately gathered his essence and spirit towards the dantian, and the burning feeling on his body made him extremely uncomfortable, but after injecting such a huge amount of essence and spirit, the feeling of using his body as a furnace finally loosened and became no longer so violent.

The most important part of the knot pill is going on, Chu Hao arranged it properly, immediately swallowed the Jinyang pill, and recovered his spirit, every time he took it, there were more than a dozen pills.

If you look at Chu Hao from the outside, you can clearly see that there seems to be a cloud of fire forming above his head, and the golden light of the Hupu Zi Gong on his body seems to be unable to suppress the rising of the firelight, and it slowly condenses and hovers above his head.

For five whole days, Chu Hao was suffering from this inhuman pain. This torture was better than not knowing the geometry when he first built the foundation, and his body began to tremble.

In five days, Chu Hao had already taken nearly a thousand Golden Yang Pills, and it was precisely by relying on such a huge amount of medicinal power that Chu Hao could now continue to bear this kind of burning without hindrance.

Turning the body into a furnace is really not something that people can do!

Chu Hao gritted his teeth and insisted, and finally on the seventh day, the spirit and the heat flow turned into one, because Chu Hao had already reached the realm of the Great Perfection of the Foundation, at this moment the spiritual power was abundant, and it was not consumed in the process of knotting the Dan, so the heat flow instantly submerged into the spiritual power, and then it seemed that the river returned to the sea, and quickly poured into the position above the dantian!

"Yudan!

An inexplicable pressure fell from the sky, and the huge pressure made him have to contend with it, which stemmed from a spiritual coercion, or a kind of "potential", which was such a momentum, which was one of the obstacles that he had to face before he got married!

Chu Hao's hands flipped suddenly, every time he changed his handprint, it seemed that there were thousands of changes, Zuihou's index finger and middle finger were bent, against his chest, and he slowly exhaled a breath of turbidity!

The Jin Dan was slowly forming in his body, and Chu Hao's essence and energy consumption was amazing, but at this time, he couldn't take the time to take the Jin Yang Dan, so he could only rely on himself to support it, and through the condensation of the heat flow, he spit out the turbid qi in his body and purify the pure Inner Dan!
