There are many, many martial arts in the Shenwu Wei Secret Vault, but most of them are external skills.

As for internal strength, of course, there are, but there are only three in total.

One of them was obtained by Ma Yuan from the Flower Picking Monk Cave Mansion.

Lei Dao had already had the experience of superimposing martial arts once, so he knew very well that superimposed martial arts must first practice a martial art to the fullest, and then he could superimpose it.

It is simple to superimpose martial arts, but if you want to superimpose the most cost-effective martial arts, you must carefully consider it.

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

He must have the shortest lifespan and stack the best martial arts.

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.

Stacked martial arts must have a focus.

For example, whether it is speed, dexterity or strength, etc., you must first have a focus, so that you can get twice the result with half the effort and get the best effect.

Lei Dao once practiced the three major hard skills, and based on the three hard skills, he practiced the Nine Turns Dragon Elephant Skill.

But whether it is the three major hard skills or the Nine Turns Dragon Elephant Skill, they are actually both strength and defense.

If Lei Dao wants to choose to stack martial arts, then he has to choose the strength type and the defense type.

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

First, he began to examine the three martial arts that exercised the internal organs.

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

Among them, the flower picking skill and the shadowless skill both belong to the type of speed and dexterity, and the way of tempering the internal organs is also very special, with the help of some external forces.

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

Even if he has practiced these two internal skills, his speed has increased greatly, how much can he increase?

Those grandmasters, could it be that the speed will be slower than the Thunder Dao?

It's simply impossible.

Therefore, it is only the best choice to continue to strengthen on the strongest point of the thunder path.

So, Lei Dao chose to superimpose the Blood Explosion Skill.

This internal skill is similar to the Nine Turns Dragon Elephant Skill, which uses qi and blood to temper the internal organs.

However, it is not as exaggerated as the Nine Turns Dragon Elephant Gong to increase the power of a dragon, and its biggest feature is to enhance qi and blood.

Qi and blood are the foundation of a martial artist, and 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 a martial artist are far stronger than those of the same level.

This belongs to a solid foundation and a relatively basic internal strength.

The introduction to the Blood Explosion Skill is very simple, similar to the Dragon Elephant Skill, so it only took one hour for Lei Dao to get the Blood Explosion Skill started.

There are a total of five layers of blood explosion skills, and it takes five years to practice them to achieve their full potential.

It consumes a few years less than the nine years of the Dragon Elephant Gong, and from this aspect, it can also be seen that the Blood Explosion Gong is far inferior to the Nine Turns Dragon Elephant Gong.

After all, even among all the internal skills that temper the internal organs, the Nine Turning Dragon Elephant Gong is top-notch!

As Lei Dao worked hard to use his abilities to achieve the fifth level of the Blood Explosion Skill, he clearly felt that his internal organs had become more tenacious, and his qi and blood seemed to have increased.

However, since there is no fusion, it is actually two internal forces, and the effects are not superimposed.

Lei Dao immediately called up his ability to check his physical condition.

Name: Lei Dao (19 years old)

Lifespan: 53 years and 10 months

External power: a total of 13 years and 6 months of life consumption (external power can be superimposed)

Golden Body Skill: Stackable

Internal power: a total of 14 years of life consumption (can be stacked with internal power)

Nine Turns Dragon Elephant Gong: Ninth Turn Dacheng (not upliftable)

Blood Explosion: Fifth Layer Dacheng (cannot be upgraded)

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

Seeing that his lifespan had been reduced by another five years, Lei Dao felt a faint pain in his heart.

However, the blood explosion skill has been completed, and it can be superimposed, and Lei Dao will no longer hesitate and immediately gather his spirit.

"Superimpose the Nine Turns Dragon Elephant Skill and the Blood Explosion Skill!"

As Lei Dao's mind moved, suddenly, the two internal forces began to superimpose.

Martial arts are superimposed, and it is actually very difficult and difficult.

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

If you want to superimpose martial arts, you must thoroughly integrate martial arts, and even be able to modify and improve this martial arts, and understand it thoroughly.

This alone is not up to nine out of nine people.

What's more, there is more than one martial art that needs to be comprehended thoroughly, at least two martial arts, and if there are several superimposed martial arts, then the difficulty of superimposing will be doubled.

Luckily, Thunder has an ability.

However, this superposition process can be saved, and it can be superimposed directly, and it does not even need to consume life.

The only thing that consumes life is the martial arts that need to be practiced to perfection before.

"Boom".

With the superposition of the Thunder Dao Blood Explosion Gong and the Nine Turns Dragon Elephant Skill, all of a sudden, there was a roar in Lei Dao's mind.

Even, a huge dragon elephant appeared above Lei Dao's head.

However, although this dragon elephant was also powerful and domineering in the past, it was not like now, it directly seemed to be covered with a layer of blood, which looked a little weird, terrifying, and even nondescript.

Lei Dao could clearly feel that his strength seemed to have increased a lot. In particular, qi and blood are directly doubled.

Qi and blood are the foundation of the body, and if the qi and blood are strong, then the potential of the body will be greater, and only then can there be great progress in other aspects.

"Well, the two internal powers have been superimposed, it's time to take a new name, the outer body can become a golden body, and the internal organs should be immortal. The superimposed internal power is called immortal power. ”

Lei Dao named the external power "Golden Body" and the internal power "Immortal", in fact, he also hoped that one day, when the external power and the internal power were superimposed to a certain extent, he could really make his golden body immortal!

Although Lei Dao superimposed the Blood Explosion Skill, his strength seemed to have improved significantly, but he was still not satisfied, he still felt that it was not enough.

"I still need to superimpose external strength, with my current strength, I am too weak against the Grandmaster. ”

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

In fact, in his memory, Lei Dao still has a few external skills, which he obtained from the Xuantian Treasure.

It's just that now Lei Dao needs to be able to practice the martial arts of the beginner without the help of external forces, so the scope has been narrowed a bit.

Soon, Lei Dao found an external skill called the Black Rock Gong.

The name is very ordinary, in fact, martial arts are indeed very ordinary, but they are relatively rare, and the sword is very extreme.

This martial art specializes in exercising the skin membrane, and it is very dangerous to practice, requiring a huge force to stimulate every inch of the skin of the body with special methods.

If you are not careful, you can get injured or even disabled.

Therefore, this external skill has not become a very widespread ordinary external skill like the golden bell jar and the iron cloth shirt.

But this black rock skill is a genuine external skill, and it is also a kind of hard skill, once practiced to the fullest, the skin will become more tough.

This is a hard skill similar to the iron cloth shirt, but it is not a martial art, it can be stacked.

Lei Dao did not hesitate at all, and immediately promoted it after entering it.

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

"Overlay. ”

Lei Dao immediately superimposed the Black Rock Gong into the Golden Body Gong.
