Since it is a necessary condition to cultivate the internal strength of martial arts to above the virtual realm, the next question is what to learn. Ling Du opened the martial arts catalog, read the content brief again, and began to choose books.

"Five Elements Gangqi" can practice the five elements of true qi, gold, wood, water, fire and earth The five elements of true qi have their own wonders, and the way of life and restraint is all in it. It's just that it's not easy to practice, and it is necessary to produce the five elements of true qi at the same time with the five meridians of the heart, liver, spleen, lungs, and kidneys, and then gather the dantian, and the five elements are absolutely equal in terms of no more than one point and no less, so as to maintain balance and stability. Therefore, it is extremely difficult to cultivate, and it is necessary to grasp the way of shengke, and supplement it with shengke at any time to ensure balance. This divine skill is the best choice for both internal strength cultivation and mental training.

"Heavenly Demon Refining Body" is a demon refining method comparable to the top cultivation exercises, which can make the cultivator's physical body strong. The higher the level, the more utility, the exercise is divided into ten layers, if you cultivate to the ninth layer, you can cast the law heaven and earth, and it is easy to step on a mountain peak with one foot. Cultivating to the tenth layer, one can break through the void with force, which is something that many Mahayana cultivators cannot do. But for human beings, due to bloodline reasons, this book can only be cultivated to the second layer, and its defensive power is a little stronger than the Golden Bell Hood Iron Cloth Shirt, but the Golden Bell Hood Iron Cloth Shirt must be used to have that kind of defensive effect, but the "Heavenly Demon Alchemy" technique is permanently enhanced, so it is not too chicken. However, even if this alchemy is practiced to the top of the second layer, it is simply unable to resist the full force of the flying sword magic weapon of the foundation building monk, and it is time-consuming and labor-intensive, so the monks are very few people to study, because there is no qualification limit, the secular martial artists are very many practitioners, of course, there are geniuses who think of ways to cultivate this magic skill to the third and fourth layers, but once practiced, the side effects are unacceptable, the mind is confused, the desire is greatly increased, the temperament changes greatly, and the heavy is the madness, and the pulse is dead, so it is called the forbidden art, there is no shortage of people with strong minds and resolute people in the world, there have been high-ranking monks and wise people who practice this technique, and it is still inevitable that a person will die, and since then, no one will take risks, and there are so many defensive exercises for cultivators, so why bother to die here. Ling Du is not engaged in DNA research, so naturally he will not practice this evil method. Ling Du didn't choose it to leave a way back for himself, in their Ling family, a competition would be held every ten years, and the first place in the competition would have to pass on "Lingyun Jue". As the treasure of the town, the "Lingyun Decision", the person who gets it must swear to the clan and must not give it to each other privately. And the cultivator, once he swears, he must swear to break the contract, which is not a joke, and there are only three ways to get "Lingyun Jue", one is to compete among the top 100 in the clan, the second is to obtain it through the consent of the patriarch and the whole clan meeting, and the third is to contribute 100,000 spirit stones. Ling Du's qualifications are extremely poor, and it is impossible to get "Ling Yun Decision" through the whole clan meeting. It is impossible to spend money to solve it, because as far as Ling Du knows, his parents' annual income does not exceed fifty spirit stones, and one hundred thousand spirit stones is a sky-high price for their family of three. However, the whole Five Elements Spiritual Root did not cultivate the exercises at all, and had to be created by oneself. Ling Du does not have any foundation and foundation, if you want to create your own exercises, you must learn from the cottage everywhere, and then constantly improve in practice, "Lingyun Decision" as the treasure of the family, the level is not low, it is naturally worth learning. Therefore, Ling Du could only obtain the "Lingyun Jue" through the intra-clan competition nine years later, and if the Heavenly Demon Body Refining reached the peak of the second layer, it could greatly increase his chances of winning.

"Xuanwu True Qi" is a peaceful method of practicing internal force, successful cultivation can open up the meridians of the whole body, not that this book is particularly superior compared to "Five Elements Gangqi", but the secret has thirteen layers, practice to the seventh layer, you can enter the realm of knowing the micro, open the inner vision, the eighth layer of Xuanwu true qi, the internal force will reach the realm of peeping void, its strength is equivalent to the peak of the cultivation of the true cultivator as for the ninth layer or more, can match the foundation building powerhouse, when basically no one cultivates to the ninth layer, so I don't know if it is true or false. Ling Du chose this secret to set a phased goal for himself.

"The Book of Knives" is a book of knives, with seventeen styles. As the so-called moon stick knife for a lifetime, learning knife skills can get started faster and increase actual combat ability. And compared to the sword, Ling Du prefers the knife, and in his cognition, the knife is more suitable for actual combat than the sword. The sword is more of an ornament for the literati, a status symbol.

"Ascending to the Heavens" is a light skill, a total of nine layers, practiced, you can leap a hundred feet, and you can theoretically improve your own reaction speed every time you practice into a layer, and you can improve your reaction speed nine times when you practice to the ninth layer, which can be described as a miracle - if you think so, then your mathematics must also be taught by a physical education teacher, because practicing to the ninth layer can improve the 9th power of your body 2, that is, 512 times the reaction speed, of course, since the establishment of Shengong, no one can practice to the ninth layer. This exercise is practiced by many cultivators, and at most they have cultivated to the fifth level, and their reaction speed has increased by more than sixty times, even for cultivators, this is already quite a powerful divine skill. Therefore, it is called the first miracle in the world.

Secular martial arts are not without quick exercises, especially the accumulation of internal force, such as absorbing other people's internal force for one's own use, which can quickly accumulate true qi. But don't do to others what you don't want to do to yourself, Ling Du is a good young man who sees righteousness and courage, and he will not take this evil path. On the other hand, Ling Du is also a kind person, if he really relies on this method to achieve cultivation, he will also become his own martial arts obstacle, forming a demon, and the gains outweigh the losses.
