These hidden acupoints are much "narrower" than the big acupoints, and the spirit elements that can be accommodated are limited. And compared to the big holes, they appear to be "congenitally insufficient", no matter how they are developed, it is difficult to reach the level of the sea of fire, at most it is only a lake of fire.

But igniting the hidden acupoint is actually very important, the higher you improve, the greater the power of the Dao technique, many wonderful Dao techniques, need the assistance of the hidden acupoint to exert the strongest power.

The more the crypt is opened and the larger the area is widened, the higher the future achievements can be.

These subtle filigree spirit elements were like red-hot wires shuttling through his subtle meridians, and the pain was far stronger than igniting the acupoint.

Song Zheng couldn't help but let out a miserable scream, a little distracted, his body shook violently, and the spirit yuan was unstable and there were signs of explosion!

Frightened, he hurriedly collected his mind and firmly controlled Lingyuan. One by one, the hidden holes were ignited, the process was painful, and Song Zheng was tortured to death. He suddenly understood: this is not the "gift" of Tianhuo, but the punishment and torture of Tianhuo: give you strength, can you bear it?

Suddenly understood this, the real stubbornness and disobedience in Song Zheng's heart also burst out, he didn't say a word anymore, gritted his teeth fiercely, and wanted to bear this pain hard!

On the east bank of the Spirit River, in the history of the Seven Heroes of the Human Race, His Majesty the Great Emperor of the Northern Expedition had the largest number of hidden caves, a total of 252 pieces! Even more than the big caves around him.

But there is no conclusion on how many hidden points there are in a person's body. Before the Northern Expedition to the Emperor, the most recognized theory was that there were as many as the Great Cave, one hundred and eight.

But after the Northern Expedition to the Emperor, this statement was self-defeating.

Not only the human race, but also the demon race. To this day, the practice is still a constant exploration. Including the exploration of oneself. The demon clan doesn't know how many hidden holes there are on their bodies. But as we all know, shemales are different.

At this time, Song Zheng used all his physical strength and perseverance to fight against the intense pain, and he didn't know how many hidden points he had ignited.

This pain is unimaginable and lasts for a very long time.

The Emperor of the Northern Expedition ignited 252 hidden points that year, and it took seven days and seven nights. Song Zheng was ignited at the same time, and it didn't take so long, but the pain increased dozens of times.

His consciousness was already blurred, and only a little spiritual light was left in his heart, which was his last and strongest belief: if he couldn't bear even this pain, what would he talk about getting out of the control of Tianhuo in the future?

The Six Flame Waves were just ordinary goods in the Heavenly Fire Reward, and compared to the true power of the Heavenly Fire, the difference was 108,000 miles.

He didn't know how long it took, but finally the pain in his body gradually subsided. His perception gradually returned.

There is a feeling of "transparency" in the body, as if I can control every trace of my strength, which is very different from before.

"It's done?" he was overjoyed, and hurriedly went to check, counting them one by one, and the more he counted, the more surprised he became, because he was gradually approaching the "limit" of the Northern Expedition Emperor!

"Two hundred and forty-eight, two hundred forty-nine, two hundred and fifty, two hundred and fifty-one, two hundred and fifty-two......"

There seems to be a lot more behind! He couldn't believe that he had surpassed the Emperor of the Northern Expedition in the Hidden Cave?!

Soon he counted clearly, and his whole body ignited three hundred and sixty hidden points.

At this moment, Song Zheng suddenly understood: this is the number of hidden points in the whole body of the human race. Because it was Tianhuo who helped him ignite it, Tianhuo must know how many hidden points there are on the human race. It simply helped Song Zheng ignite them all at once.

Solved a mystery that had plagued the human race for tens of thousands of years, but Song Zheng did not show any excitement. Because this is more and more confirmed, the heavenly fire is high, not only mysterious, but also noble!

Each hidden cave has been opened up into a lake of fire by the heavenly fire, and it has reached the extreme. And the power of the Six Flame Waves of Light only consumed less than thirty percent!

Song Zheng took a deep breath, temporarily distracted all distractions and worries, and silently recited in his heart: "Vein River Realm!" The power rolled out, penetrating one of his twelve meridians.

The vein river realm is based on the ignited acupoints on the meridians as nodes, connecting and penetrating, completely widening the entire meridians and becoming a big river.

One of the most important aspects of this process is to visualize the river – try to visualize the largest and widest river you have ever seen.

It is said that the extent to which the river can be developed has a great deal to do with visualization.

Song Zheng followed his father to the south and north, and Song's father read the books of sages and believed in the words of sages all his life, insisting on reading thousands of books and traveling thousands of miles. He took his son to see the three largest rivers of the Hongwu Heavenly Empire.

But Song Zheng had just begun to visualize, but suddenly a strange thought came into his mind. With a bang, Song Zheng felt his consciousness hanging high above the clear sky, overlooking the entire earth from a height of hundreds of thousands of zhang.

The mountains and rivers are not so tall in his eyes, but on the earth, there are two rivers that are majestic, and even from his current perspective, they are magnificent.

The two rivers are far apart, but in his field of vision, they seem to echo each other.

They are equally vast and boundless, like the sea. They are also very long, coming and going, and they can't see the head and tail with their eyes. They also contain thousands of people, and in the river, there are all kinds of powerful creatures that live in abundance, far more than on both sides of the river.

There is a difference between the clear water of one large river and the exuding vigorous aura, while the other is a mixture of dark water and contains an incomparably powerful power of the underworld.

The two rivers are faintly yin and yang, separated on both sides of the continent.

Song Zheng's sudden abruptness: one is the spiritual river on which the human race depends, and the other is the holy river of the demon race: the Styx!

If the largest rivers in the world are to be these two. Unsurpassed.

But Song Zheng had never been to the Spirit River or the River Styx—let alone him, and the ordinary Xuantong Realm would not dare to approach. Needless to say, the River Styx is mighty and endless, and on both sides of the river bank is the place where the aura of heaven and earth is the strongest in the entire continent, and any place is a blessed land.

Not only can the human race cultivate here get twice the result with half the effort, but even the desolate beasts and reckless insects will become extremely powerful here.

Therefore, although the Spirit River nourishes the entire continent, the two banks of the Spirit River are the most dangerous places on the entire continent, and they are all over the world. In addition to these extremely powerful desolate beasts and reckless insects, the sects that have established sects on both sides of the strait are all ancient great sects, and any one of them has been inherited for tens of thousands of years, and their strength is comparable to that of a dynasty.

Without the strength of the Heavenly Pass Realm, there is no need to send him to death at all.

Song Zheng quickly understood that this was Tianhuo's "gift". He smiled unceremoniously. Keep visualizing two great rivers. The river was surging, and the first vein in his body was gradually taking shape.

But what surprised him was that this vein river actually had yin and yang poles!
