Realizing the benefits of the cultivation speed, Sun Xiaohan was excited for a while, and then felt the refreshment of ten times the vigor of running, and slowly collected the work. Thinking back to the experience just now, Sun Xiaohan couldn't help but be a little afraid, he was so crazy, the first time he used the spirit, it was just a handful of crazy. Fortunately, even if something goes wrong, the spirit you have lost can be ignored directly, but it will have a great impact on your heart.

Fortunately, the result is still satisfactory, and as long as it completes a fusion with the "Golden Soul", there will be no more trouble in the future, as long as a little bit of the spirit is integrated into the jade, the full effect of the jade can be stimulated. After receiving the credit, Sun Xiaohan was still excited for a long time.

Slowly retracting his heart, Sun Xiaohan picked up another book. This book seems extraordinarily quaint, but it always feels magnificent. On the cover page was written "The Source of Qi Jin", which turned out to be a book dedicated to Qi Jin, which aroused Sun Xiaohan's full interest.

Sun Xiaohan looked at the ancient book in his hand, and always felt that he couldn't see through it. But feeling is feeling, after all, there is no conclusive evidence, so Sun Xiaohan just gave up. Open the ancient book, which tells the origin of qi and the division of grades.

Classification of levels, Sun Xiaohan is naturally familiar with it, but the origin is unknown, after all, he has never thought about this kind of problem. The book describes in detail the origin of Qi Qi and some basic common sense.

Qi Jin is actually divided into two parts, one part is called "Qi" and the other part is called "Jin". The book also describes these two different substances separately, as well as their histories:

Strength, the power of heaven and earth. Formless and colorless, pregnant in heaven and earth, stored in the dantian, traveling in the meridians, hair in the whole body, and increasing in sharp weapons. People who cultivate strength are good at work, and they are condensed in the fist and blade, and their skills are invincible and unfavorable.

Angry, the spirit of heaven and earth. It is also formless and colorless, pregnant in heaven and earth, stored in the dantian, traveling in the meridians, hair in the whole body, and increasing in sharp weapons. Those who cultivate qi are good at supplementing, and the utensils that gather qi in their hands are supplemented by other uses.

After reading this opening, Sun Xiaohan had a preliminary understanding of the basic division of qi. Continuing to look down, it is written in the book that in ancient times, cultivators were divided into qi cultivation and jin cultivation. Jin Xiu is the main offensive force on the battlefield, and Qi Xiu is the support of the rear.

Jin Xiu is good at attacking the opponent with all kinds of divine weapons, and strives to defeat the enemy with one move. When attacking, the tricks are wide open and closed, and they are full of domineering, but they are good at attacking and not good at defending, and they often just blindly move forward, and there is no room for maneuver.

Qi cultivation is good at using its own aura, supplemented by various formations, spiritual weapons and other things, creating illusions to confuse the enemy, or training and treating the wounded on its own side, and its own defense is extremely strong. However, Qi Xiu has almost no attack power, so it can only appear as a support on the battlefield.

Later, a pair of brothers surnamed Ning appeared, the elder brother was Jin Xiu, and the younger brother was Qi Xiu. The two of them cooperate tacitly on the battlefield and are invincible. But the two of them are not one person after all, and in a battle, there were still mistakes in coordination, and the younger brother almost died.

Later, the two brothers began to think that "qi" and "jin" are both spiritual objects of heaven and earth, they are originally the same root, why should they be separated, and the methods of cultivation and use are also similar, there is almost no difference. If you can combine these two spiritual things into one and learn from each other's strengths, wouldn't you be invincible?

After decades of research, the brothers finally succeeded in merging "qi" and "jin" into one, and named them "qi jin". They found that after the fusion of these two internal forces, "energy" is the main "qi" and supplemented. This "Qi Jin" inherited almost all of the abilities of the "Jin" main attack, while the condensation gas cover of the "Qi" and the ability to create illusions were almost unusable. Although it is possible to create illusions with the help of some auxiliary items, the air shield cannot be used in any way.

But to the surprise of the two brothers, although they could not use the qi cover after fusion, their physique and soul were tempered by "qi". It is the physique that becomes stronger and the soul more powerful. The two brothers took advantage of this change and created new moves. Use the spirit to pull the energy, condense it on the blade, so that the blade can emit sword rays and sword moves. The attack distance is long, and the power is huge, and it has the effect of sweeping thousands of troops. However, on the other hand, it is a great burden on the body, and it requires a lot of physique.

These two used this trick unexpectedly in a national war, and the result was naturally a great defeat of the enemy. Later, the two brothers announced the method of fusion of qi and cultivation to the world, so that everyone could cultivate. Gradually, many masters gradually improved the cultivation methods of the original exercises, so that people could directly cultivate qi from the beginning.

According to the hierarchical division of qi, it is divided into two main stages, "Hinayana and Mahayana", and according to the capacity of qi in the dantian, it is divided into six stages of Hinayana "first pregnancy, breaking the wall, Nachuan, void fullness, Yingyi, and casting solid", each stage is divided into three sections, and each section is divided into three layers; Mahayana "Tibetan Mountain, Rongwu, Lanyun, Huihai, Kuntai, and Jingyu", and this hierarchical division has also been followed to this day.

After reading it, Sun Xiaohan let out a sigh and sighed: "The great wisdom of the ancients, I am not enough to wait for today's people! I have never heard that qi can be condensed on the weapon and released in the form of 'mang'. I think it must have been passed down for thousands of years and disappeared from the world!"

In fact, Sun Xiaohan was wrong, this kind of trick did not disappear, but was replaced. Because later generations found that the condensation of qi is emitting, and the burden on the body is extremely heavy. Some people invented new moves, still using weapons as the carrier, but the energy was condensed but not released. The reason is very simple, the original Jin Xiu was good at close combat, but now he condenses his energy in a ball and sends it out at one point. Not only does the power surge, but the burden on the body is minimal. It has gradually been sought after by people, and at the same time, it has also set off an atmosphere of martial arts for everyone.

Of course, it is not easy to gather energy on the blade. It is necessary to have a strong foundation of strength as the foundation in order to condense the strength and the blade. Moreover, different grades of blades can withstand different amounts of energy. The better the blade, the more energy it can withstand, and the greater the increase in energy.

Although the green steel sword used by Sun Xiaohan was extraordinary, it could be regarded as a mass-produced blade. As long as it is a martial arts hall with some qualifications, as long as the level of strength is as high as Nachuan, it is to enter the realm of martial artists. The martial arts hall will give him a green steel sword.

The "Autumn Moon Cold Dew" sword given to Sun Xiaohan by Sun Jingming is a rare divine weapon. Even if you reach the realm of the Martial Saint, you can still use it. And the "Emerald Blue with Water" sword is a peerless divine weapon, even if it is a martial god, it can be used. Of course, the current Sun Xiaohan doesn't know all this.

As for condensing the strength of the blade, Sun Xiaohan still knows it. But now he is far from being able to do this, if the grade can break through to the realm of a martial artist, he will naturally be able to condense his strength on the blade.

Thinking of this, Sun Xiaohan unconsciously touched the wrench on his hand, after all, he had this perverted cultivation accelerator, coupled with the perverted qi purification ability in his body, it was only a matter of time before he broke through.
