There are many martial arts in the secret library of Shenwu guard, but most of them are external skills.

    As for internal skills, of course, there are, but there are only three.

    One of them was obtained by Ma Yuan from the flower picking Buddhist cave.

    Lei Dao has had one experience of superposing martial arts. Therefore, he knows very well that superposing martial arts must first practice a martial arts to a great degree, and then superpose it.

    Superimposing martial arts is simple, but if you want to superimpose martial arts with the best cost performance, you must consider it carefully.

    You can''t stack any martial arts. Of course, Lei Dao wants to be so "willful", but his "life" is not allowed. At present, it has only a life span of more than 50 years, and can''t afford to waste at will.

    He must stack the best martial arts with the shortest life.

    It doesn''t have to be the strongest martial arts, but when used on Lei Dao, the effect must be the best.

    Then you must choose a general direction before stacking martial arts.

    The superimposed martial arts must have a focus.

    For example, whether it is speed type, dexterous type or power type, we must first have a focus, so that we can get twice the result with half the effort and obtain the best effect.

    Lei Dao once practiced three hard skills, and based on the three hard skills, he became the nine turn dragon elephant skill.

    However, both the three hard skills and the nine turn dragon elephant skill belong to the power type and defense type.

    If Lei Dao wants to choose superimposed martial arts, he must choose strength type and defense type.

    After choosing the direction, Lei Dao began to choose martial arts.

    First of all, he began to check the three martial arts for exercising the inner organs.

    These three internal skills are blood explosion, flower picking and shadowless.

    Among them, flower picking skill and shadowless skill belong to the type of speed and dexterity, and the way to exercise the inner organs is also very special, so we have to rely on some external forces.

    Even if Lei Dao wants to practice now, he can''t practice. Moreover, these two internal skills don''t conform to the plan made by Lei Dao before.

    Even if he practices these two internal skills, how much can he increase his speed?

    Those masters, are they slower than Lei Dao?

    It''s impossible.

    Therefore, it is the best choice to continuously strengthen the strongest point of thunder track.

    Therefore, Lei Dao chose the superposition blood explosion skill.

    This internal skill is similar to the nine turn dragon elephant skill. It uses Qi and blood to temper the internal organs.

    However, it is not as exaggerated as the nine turn dragon elephant skill to increase the power of one dragon. Its biggest feature is to enhance Qi and blood.

    Qi and blood is the foundation of martial arts. The blood explosion function improves the strength of Qi and blood in the process of constantly tempering the internal organs, so that the Qi and blood of martial arts is far stronger than that of the same level.

    This is a basic internal skill to strengthen the foundation and cultivate the yuan.

    The introduction of blood explosion skill is very simple, which is similar to the Dragon elephant skill. Therefore, Lei Dao only used one hour to introduce blood explosion skill.

    There are five layers of blood explosion skill. It takes five years to practice it until it is completed.

    It consumes a few years less than the nine years of dragon Xianggong. From this point of view, it can also be seen that the blood explosion skill is far less than the nine turn dragon Xianggong.

    After all, jiuzhuan dragon elephant skill belongs to the top even among all the internal skills to temper the internal organs!

    As Lei Dao tried to use his power to practice the blood explosion skill to the fifth level, he obviously felt that his inner organs became more tenacious and his Qi and blood seemed to be more.

    However, because there is no fusion, it is actually two kinds of internal skills, and the effects are not superimposed together.

    Ray Dao immediately called out his ability to check his body.

    Name: Lei Dao (19 years old)

    Service life: 53 years and 10 months

    External skill: 13 years and 6 months of life (external skill can be added)

    Golden body skill: can be superimposed

    Internal skill: totally consumes 14 years of life (internal skill can be superimposed)

    Nine turn dragon skill: the ninth turn achievement (can''t be improved)

    Blood explosion skill: the fifth level of success (can''t be improved)

    Qigong: a total life of one year and three months is consumed (Qigong can be superimposed)

    Seeing that his life expectancy was reduced by five years, Lei Dao felt a faint pain in his heart.

    However, the blood explosion skill has become great and can be superimposed. Lei Dao no longer hesitated and gathered his spirit immediately.

    "Superimpose nine turn dragon elephant skill and blood explosion skill!"

    As Lei Dao''s mind moved, the two internal skills began to stack.

    The superposition of martial arts is actually very difficult.

    It is even several times more difficult than simply practicing martial arts.

    If you want to superimpose martial arts, you must thoroughly master martial arts, and even modify and improve this martial arts, and have a thorough understanding.

    Ninety nine percent of people can''t achieve this alone.

    Moreover, there is more than one martial arts, at least two martial arts, which need to be understood thoroughly. If there are several superposed martial arts, the difficulty of superposing will be doubled.

    Fortunately, ray Dao has powers.

    It can save the stacking process. It can be stacked directly without even consuming service life.

    The only thing that consumes life is the martial arts that need to be practiced to great success.

    Boom.

    As Lei Dao superimposed blood explosion skill and nine turn dragon elephant skill, Lei Dao suddenly roared in his mind.

    Even, a huge dragon elephant appeared on the top of Lei Dao''s head.

    However, in the past, although the Dragon elephant was also powerful and domineering, it didn''t look like this. It directly seemed to be covered with a layer of blood clothes. It looked strange, scary and even nondescript.

    Ray Dao could clearly feel that his strength seemed to have increased a lot. Especially HP, which can be doubled directly.

    Qi and blood is the foundation of the body. If you have strong Qi and blood, you will have greater physical potential and make great progress in other aspects.

    "Well, the two internal skills have been superimposed. It''s time to take a new name. The external body can become a golden body, and the internal organs should be immortal. The superimposed internal skills are called immortal skills."

    Lei Dao named his external skill "golden body" and his internal skill "immortal". In fact, he hopes that one day, when the external skill and internal skill are superimposed to a certain extent, he can really make his golden body immortal!

    Although Lei Dao superimposed the blood explosion skill, his strength seemed to have been greatly improved, he was still dissatisfied, and he still felt that it was not enough.

    "I also need to add external skills. With my current strength, I''m too weak against the guru."

    Lei Dao gritted his teeth and began to look for other external skills.

    In fact, in his memory, Lei Dao also had several external skills, which he got from the Xuantian treasure.

    However, now Lei Dao can practice his beginner martial arts without the help of external forces. Therefore, the scope is narrowed down.

    Soon, Lei Dao found an external skill called black rock skill.

    The name is very common. In fact, the martial arts are very common, but it is rare. Moreover, the sword moves at a wrong edge, which is very extreme.

    This martial arts is specialized in training skin mask. It is very dangerous to practice. You need to use great force to stimulate every inch of your skin with special methods.

    If you are not careful, you will be injured or even disabled.

    Therefore, this external skill has not become a widely spread common external skill like the golden bell jar and iron cloth shirt.

    But this black rock skill is a genuine external skill, and it is also a kind of hard skill. Once you practice it to great success, the skin membrane will become more tenacious.

    This is a hard skill similar to the iron cloth shirt, but it is not the same martial skill. It can be superimposed.

    Lei Dao didn''t hesitate. He immediately promoted him after he started.

    This martial arts also consumes a year and seven months of life.

    "Overlay."

    Lei Dao immediately added the black rock skill to the golden body skill.
