PS: The original 12 layers of the "Taiyi Heart Sutra" have been changed to 9 layers.

..................

The Taiyi Heart Sutra is divided into nine layers.

They correspond to the eight veins of the Yang Pulse, the Yin Pulse Pulse, the Yang Pulse Pulse, the Yin Pulse Pulse, the Belt Pulse, the Chong Pulse, the Ren Pulse, and the Du Pulse.

These eight meridians. Neither directly from the heart. There is no relationship between the outside and the inside, so it is called the 'Strange Sutra', each of which runs through the body and connects several large acupoints.

Every time a meridian is penetrated, it is considered to break through one layer, and the true qi is one point stronger.

The other six veins are okay, but the second vein is the most difficult to penetrate.

Ren Du's two veins connect the hands and feet, communicate with the five elements, and if the luck is slightly improper, it will go mad and damage the lungs.

I don't know how many first-class masters on the rivers and lakes failed to attack the second pulse of Ren Du, resulting in the waste of martial arts, and even a whimper.

Just this small step has become a moat in martial arts! How many swordsmen and heroes have been stopped!

But once it breaks through, its strength will increase exponentially, and it will become a top master in one fell swoop, which can be called a carp leaping into the dragon gate.

Of course, these are all for people in the world, and for those in the immortal sect who have the inheritance of earth immortals or even heavenly immortals, it is a different situation.

For them, penetrating the second vein of Ren Du is just touching the edge of entering the Dao, which can only be compared.

The only thing that is gratifying is that whether it is a person in the secular martial arts or a person in the Xianmen, it is very difficult to penetrate Ren Du and open up the eight veins of the Qi Jing.

Theoretically, as long as Han Cheng can penetrate all the eight veins of the Qi Sutra and run the True Qi Great Zhou Tian, he will be regarded as having successfully entered the realm of the ninth layer of the Great Perfection of the Taiyi Heart Sutra.

Because of the reason for the spiritual fruit washing and marrowing, Han Cheng's physique has been greatly improved, and the true qi in his body is too full, and the total amount is far more than that of ordinary monks in the early stage of qi training.

Driven by the heart method, the true qi surged out of the dantian, continuously connecting the two major meridians of the yang and yin stilt veins, and the total amount of true qi more than doubled all of a sudden, and steadily stepped into the middle stage of qi training, and the progress of cultivation can be described by the word 'leaps and bounds'.

The difficulty of cultivation in this world is well known, just one Qi cultivation realm, under normal circumstances, if you want to cultivate it to the fullest, it often takes ten or eight years for a good root bone, and it often takes thirty or forty years or even longer for an ordinary root bone.

Life is short, and even if the Qi cultivation is completed after thirty or forty years, how can there be much lifespan to continue cultivating, so it is not for nothing that the major Xuanmen Authentic Sects recruit disciples who often only recruit good materials and beautiful qualities with immortal roots and fairy bones.

Of course, the root bone qualification is important, but it is not the only one, in addition to the root bone, there are many factors that affect the progress of cultivation, such as exercises, understanding, diligence, natural treasures, elixir to wash the scriptures and cut the marrow, and so on.

If you don't have a high level of comprehension and are not diligent in your practice, you will definitely have a great impact on your cultivation speed, there is no doubt about that.

In addition to this, the choice of exercises and the use of elixirs are also important.

A superior immortal path secret book, if there is a famous teacher's guidance and proper practice, the speed of cultivation can be increased a lot, and the foundation is very stable, there is no fear of demons, and the power is much stronger than ordinary exercises, much more powerful.

The reason why Emei can lead the group and sit firmly on the throne of the world's first Xuanmen is because of a person who has already preached the power of the Golden Immortal and is known as the first person in Taoism for thousands of years.

In addition to having the inheritance of the first-class immortal Dao secret codex, taking some heavenly treasures and elixirs can improve the physique by washing the meridians and cutting the marrow, and you can also quickly increase the speed of cultivation.

Especially the treasure of heaven and earth, the spirit grass fairy fruit, the effect is remarkable, and there are no side effects, unlike the pill pill, there are some erysipelas in the refining process, a little consumption, the disadvantages are not obvious, overdose, harmful to the body.

However, after all, the number of natural treasures is scarce, and they can not be found, and those who are not blessed cannot get it. Han Cheng was able to get some purple spirit fruits to improve his cultivation, it was a fluke, and it was difficult to copy.

"There are still more than a dozen purple fruits in the cave that have not been eaten, I don't know how much spiritual effect is left after being stored for so many days?"

Thinking of this, Han Cheng immediately turned to the back mountain and went straight to the hidden small cave.

After entering the cave and making sure that there was no one around, Han Cheng stepped forward and took out the dozens of purple fruits hidden in the cave wrapped in cloth and took them out.

Under the sun, although these purple fruits are still fragrant, they are no longer crystal clear, and the color of the skin is much darker than when they were first picked.

Smelling the faint aroma of the purple fruit, Han Cheng felt distressed for a while, and no longer had the slightest hesitation, he ate all those purple fruits into his stomach in one go, and soon a burst of heat rose in his abdomen, and sure enough, with the breakthrough of the realm, the aura contained in the purple fruit can be absorbed by the body again!

Han Cheng struck while the iron was hot, and ran the Taiyi Heart Sutra with all his might, carrying the true qi and refining some of the remaining essence in the purple fruit.

Time feels like it's passed......

After a whole day and night, Han Cheng recovered from his state of concentration, and when he opened his eyes, a wisp of essence flashed, and he opened his mouth and spit out a turbid breath.

With the majestic spiritual power of the purple fruit, Han Cheng penetrated the Yangwei vein in one breath and rushed to the third layer of the "Taiyi Heart Sutra", and the true qi in his body increased by three points, and his whole body was full of strength.

As the true qi circulates throughout the body and nourishes the body, the epithelial membrane on the body begins to swell and contract, and it becomes extremely sensitive, as long as a little strong wind blows, the epidermal organs can be transmitted to the brain through the nerves.

There are many sensory organs on the epithelium, which can be transmitted through nerves to the back of the spinal cord, and then to the brain, as well as sweat glands, hair follicles, hair, and other accessory organs.

Han Cheng took a large amount of spiritual fruit in one go, and in the process of refining, the physical body was constantly improved and strengthened, and the potential of the human body was further developed, which increased the sensitivity of the sensory organs on the epithelial membrane and the conduction of its nerves to the brain, and initially achieved the effect of listening and understanding.

When facing the enemy, you can use this to detect the opponent's incoming situation, seize the opportunity, and greatly improve the ability to respond to contingencies.

Trying to suppress the excitement in his heart, Han Cheng immediately unleashed the Five Fowl Cultivation Fist, his whole body tendons were strong in expansion and contraction, his explosive power was fierce, and his body was very agile.

Bang!

I was really angry, and I punched a hard tree with a thick bowl mouth, and with a click, it broke!

Click, click, click......

Then, Han Cheng's fist shadow flew over, carrying a strong and courageous aura, and struck dozens of punches at the surrounding trees, the fist wind roared, almost tearing the air, and the trees were hit hard, either breaking or cracking!

A set of punches was beaten, and his face was not red or panting.

The breath is continuous and far-reaching, the physical strength is long, and the advantages of the mid-stage realm of qi training have been perfectly demonstrated at this moment!
