It's definitely going to break through. Legend has it that it is not easy for strange beasts to attain the Tao, and there is Neidan! Tang Zheng didn't know what this Neidan was, but there was a faint guess in his heart, it was not that he had already taken Neidan.

Tang Zheng didn't know that although the strength of this black snake was extremely strong, it had not yet reached the level of possessing Neidan.

Whether it's a demon beast or a spirit beast, it's extremely difficult to practice. On earth, one of the first conditions is to live a long life. If you don't live long, everything is empty. But in today's society, pollution is serious. The climate is abnormal, coupled with poaching, so much hunting, where can there be room for wild beasts to survive. Many organisms are extinct.

Here in the Valley of the Gods, isolated from the world and without natural enemies, there is a chance to live. Both the white ape and the black snake have the prerequisite for living long.

Secondly, the aura must be sufficient, and the treasures of heaven and earth must be there. Let's not talk about aura, look at the great rivers and mountains in China. The aura here is definitely sufficient. As for the treasures of heaven and earth. There has never been a shortage of these in the medicine valley. Taken together, rare breeds such as white apes and black snakes have emerged.

After the demon beasts have the will to cultivate, they all naturally cultivate according to some things inherited by the bloodline, and the most important internal organs of snakes are snake gall bladders. In the previous cultivation, all the energy was gathered in the snake gall. Only after truly transforming from a spirit beast to a demon beast can this have Neidan.

Tang Zheng didn't know about this. It wasn't until a long time later that Tang Zheng understood these things.

Absorbing the essence energy of the black snake's whole body, the true qi in the body is vigorous. It washes over the meridians like a tidal wave. Tang Zheng's heart also became excited. This time the medicine valley really came to the right place, although it was full of dangers. But. So what, Tang Zheng's view of danger is becoming more and more mature now. The so-called wealth is sought in danger. There are no such dangers. How can I grab Yang Kai's baby, and how can I get the opportunity now.

Close your eyes and concentrate. Sitting cross-legged, his mind was completely silent, the Yin and Yang Heart Sutra was running, and according to the original breakthrough method, Tang Zheng began to control the true qi in an orderly manner to gradually condense and purify this violent energy.

After looking inward, Tang Zheng also found that compared with his own true qi, the energy that gushed out from the black snake seemed to be mixed. There's a bloody aura, and on top of that, there's a feeling of intense desire.

"Snake nature is lewd, this time, I'm afraid it's broken!" Tang Zheng chuckled in his heart.

The Yin and Yang Heart Sutra already has the effect of promoting Yang Qi, and when I first cultivated, I was 'arrogant and dissatisfied' every day, and now. Added the energy of this black snake. Don't suffocate yourself.

The high-speed operation and circulation of the true qi, the majestic energy of the black snake was also gradually absorbed by Tang Zheng. In the process of absorption, a large number of impurities were also discharged from Tang Zheng's body. Some of these impurities are Tang Zheng's own impurities. Every level breakthrough. For Tang Zheng, it was an improvement in physical fitness.

In addition, this time, the impurities came more from the black snake's energy. Tang Zheng also has his own views on this. In the legends, there are also those strange tales of ancient times. But every goblin has a demonic aura.

Now that I think about it, judging from the situation of this black snake. It should be caused by the miscarriage of true qi.

One week, two weeks...... Dozens of weeks down. The sky within this line of heaven also darkened.

For a long time, even at noon, the light was dim, and overhead, the rock walls on both sides were closed together, with only the occasional gap in which sunlight poured down, if it weren't for it, it would be like a tunnel.

Now, the sky outside is getting darker, and it's suddenly dark.

When the white ape saw this, he was also anxious, and the animal's natural instinct made the white ape dare not stay outside. glanced at Tang Zheng. I wanted to leave, but I still stayed.

After several hours of operation, the energy of the black snake was absorbed by Tang Zheng, and around Tang Zheng, it was already covered with a layer of stench. The white apes all took the initiative to leave a distance of more than ten meters.

At this point, all the preparations have been made. Tang Zheng began to guide the True Qi towards the link between the Twelve Righteous Meridians and the Eight Veins of the Qi Sutra and began to impact it.

The meridians of the whole body of the human body, the twelve meridians and the eight strange meridians, are all linked, and this connection is maintained through the meridians throughout the body.

The veins are like the pores of the human body, and countless veins connect these great meridians. It's like a network of capillaries between arteries and veins.

Arterial blood circulates throughout the body and provides the body with essential oxygen and nutrients. Then, the heart is transferred from arterial blood to venous blood, and then from the capillaries, to the respiratory and digestive systems, and the oxygen and energy are replenished to complete a process of addition and perfusion. The zuihou completes the circulation, forming new arterial blood.

The same goes for the meridians. Moreover, meridians are not only independent systems, but also closely related to muscles, skin, and major circulatory systems.

Take the treasure of heaven and earth. What thousand-year-old Ganoderma lucidum, 10,000-year-old Zhuguo or something. It can increase the cultivation of ancient warriors, in fact, this is the mechanism.

However, if you want to enter the meridians, the first thing you have to break through is the big barrier between the meridians, which is the most difficult thing.

Breaking through the realm level is not the first time for Tang Zheng. It's a familiar road. According to the way he broke through in the past, he carefully controlled his true qi and began to impact towards the barrier between the meridians.

However, this time, what Tang Zheng didn't expect was that he was originally mentally prepared. In the past, except for the earliest one or two layers, the breakthrough was not all about doing your best, and the barriers between the meridians were not so easy to break through.

But this time, Tang Zheng worked hard, and when he hit the barrier, it was like a person hitting the door, the previous doors were locked, and every time he needed to hit the door vigorously. This time, even in my habitual thinking, I feel that the door is locked, and I look at it. So, with all his strength, when he struck again, he suddenly found that the gate was only hidden. It's not closed at all.

All of a sudden, Tang Zheng's true qi was almost uncontrollable. rushed directly into the veins.

The door of the void, with a strong force to hit that is to find their own fall. Tang Zheng is also feeling this way when he hits the meridians now.

The true qi rushed directly into the veins, and it took a lot of strength to ease up and go towards the Yin veins.

According to the impact order of the Yin and Yang Heart Sutra, the first to break through is the Yin and Yang two meridians, and after the two meridians break through, this can be regarded as the completion of the cultivation of the six layers of innate beings. Next, the two-dimensional veins of yin and yang are the seventh layer. The second pulse of the oppression belt is the eighth layer. zuihou, open up the second vein of Ren and Du, and run through the bridge of heaven and earth. This is the ninth layer.

The ninth layer mentioned here is according to the rating method of the ancient martial arts world today, if it is according to the thinking of the ancients, this is the ninth layer of the day after tomorrow, only after the second pulse of Ren Du is opened, it runs through the bridge of heaven and earth. The meridians of the whole body form a complete Zhoutian, which can be regarded as entering the innate realm.

Like the serious barriers, the barriers of the Yin Vein are also extremely relaxed. At this moment, with the operation of the true qi and the deepening of the fusion of the black snake's energy, Tang Zheng even felt that his whole body was on fire, and in his mind, there was a desire that could not be left.

With the breakthrough of the Yin Kick Vein, suddenly, an incomparably pure Yin Spirit Qi from within the Yin Kick Pulse was also mixed into Tang Zheng's True Qi.

Although it was only extremely rare, the purity and quality of the true qi far exceeded Tang Zheng's true qi. It's like a chemical reaction. Tang Zheng's true qi quickly calmed down. The deepest desires in my heart also disappeared without a trace in an instant.

After entering this level, Tang Zheng's whole person entered an ethereal realm, the true qi operated on its own, broke through, and under the promotion of the black snake's energy, the Yang Ji vein also rushed away. This is a breakthrough in the small realm. It is also a vein. The barrier in the middle is almost zero, whether it can be broken through or not depends entirely on the accumulation of true qi, after Tang Zheng obtained the energy of the black snake, the accumulation of true qi is completely sufficient. So, this time it's a matter of course.

After the true qi broke through and entered the eight veins of the Qi Sutra. According to the hierarchical distribution of the Yin and Yang Heart Sutra, Tang Zheng broke through to the realm of the twelfth layer. According to the division of the modern ancient martial arts world, this is the innate six layers, and according to the ancient division, it is the acquired six layers.

True Qi began to work around a new cycle formed between the Twelve Righteous Meridians and the Twist Pulses. It's different from what it used to be. From now on, with each cycle, the True Qi was refined between the veins and the veins, and the amount of True Qi did not increase much compared to before the breakthrough. Instead, there are fewer. However, the quality of True Qi began to be refined gradually. Tang Zheng himself could feel that his true qi was more condensed and pure. The energy contained in it is also getting stronger and stronger.

At the end of the night, Tang Zheng spent all his time in this kind of cultivation. Until dawn, beyond the first line of sky, the canyons began to be a little bright, and the sky was white.

Tang Zheng also slowly gathered his true qi and opened his eyes. In this darkness, it can be seen that the moment Tang Zheng's eyes opened, a fine light flashed away.

With his waist straightened, he had already stood up, and Tang Zheng said to himself: "Is this the change after breaking through the Wonder Sutra?" Sure enough, this is the only way to conform to common sense. ”

Tang Zheng now also understands a little, true qi can't grow endlessly, and the capacity of the meridians is always limited, but what can he rely on to improve his strength? Quality, and only quality. The accumulation of quantity is followed by a qualitative leap.

In a daze, there was a sound next to him, and the white ape had already rushed over from the side, and Tang Zheng also laughed when he saw the white ape. (To be continued......)
