In the Lei Yuan Stone, there is a pure thunder attribute Yuan power.

The first condition for cultivating the Thunder Sound Sword Qi Technique is to absorb the thunder power and cleanse the lungs.

The three martial arts of the Zhou family, the Black Sea Fury Jiao Fist and the Black Water True Technique are in the same line, so it didn't take long for Zhou Chen to get started, reach the realm of initial succession, and then use the martial arts system to ascend to Dacheng.

However, in order to reach the initial realm of entry, the Thunder Yin Sword Qi Technique must be used to cleanse the lungs with thunder power.

If there is no Lei Yuanshi, if you want to cultivate the Thunder Sword Qi Technique, you must bear the baptism of thunder, which is almost an act of looking for death, the thunder contains the power of heaven, and the violent power in it, even the martial arts master does not dare to carry it.

The thunder power in the Lei Yuan Stone is extremely pure, and it is extremely gentle, not violent.

Zhou Chen returned to the room of Qingyun Courtyard, put the Lei Yuan Stone in the palm of his hand, and then ran the exercises, breathed the thunder power in the Lei Yuan Stone, guided into the lungs according to the method in the Lei Yin Sword Qi Technique, and began to cleanse the lungs.

The purpose of using thunder to cleanse the lungs is to let the lungs absorb the thunder power, and at that time, the thunder sound sword qi technique is the real power of thunder, just like the real heavenly thunder descending into the world.

The Thunder Yin Sword Qi Technique is divided into two steps.

The first step is to cultivate the thunder sound, and then the second step is to turn the thunder sound into sword qi.

After cultivating the first step, the Lei Yin Sword Qi Technique is equivalent to a sound wave skill, killing people with sound.

If you have cultivated the second step and can unleash the Thunder Sword Qi, then the means can be called amazing.

What is Thunder Sword Qi? It has the extreme speed of thunder and lightning, and almost no one can dodge it.

With Lei Yuanshi's assisted cultivation, Zhou Chen quickly mastered the Lei Yin Sword Qi Technique.

Then, use the martial arts system to improve the realm of the Thunder Yin Sword Qi Technique, from the first to the small one, and then to the big one.

When the Black Sea Fury Jiao Fist reached Dacheng, it only consumed three hundred units of energy, while the Thunder Yin Sword Qi Technique nearly doubled, consuming five hundred units of energy, and the remaining seven hundred units of energy.

According to the information in the martial arts system, if it is a system in an intact state, it can be created out of nothing, with enough energy to provide, not to mention just creating thunder attribute energy, and even creating laws out of thin air.

However, this martial arts system was severely damaged in the great war in ancient times, and although it was repaired on its own after a long time, there are still many functions in it that have not been restored, and can only be upgraded according to the situation of 'being'.

The Lei Yin Sword Qi Technique reached the Dacheng realm, and Zhou Chen's strength was at least doubled.

This is still Zhou Chen's cultivation realm is too low, and it is difficult to exert the full power of the Thunder Sound Sword Qi Technique, even if it is refining Gang Chengyuan, at most, it can only exert the power of the Thunder Sound Sword Qi Technique by three or four percent.

After all, this is a high-grade martial arts at the ground level, and if you don't reach the Yuan Martial Realm, you can't exert your full power at all.

Only by reaching the Tian Yuan level can he perfectly display all the mysteries of the Thunder Yin Sword Qi Technique.

At that time, even if he met a martial arts master, he might not have the strength to fight.

The two earth-level martial arts, the Black Sea Fury Jiao Fist and the Lei Yin Sword Qi Technique, Zhou Chen has reached the full stage, and the next thing is to concentrate on cleaning the viscera, because the lungs have absorbed the power of Lei Yuanshi, all the impurities have been eliminated, and what remains to be practiced is the rest of the viscera.

Small black particles as fine as fine dust are expelled from the body.

This is the toxin hidden in the viscera, and the use of Gangqi to cleanse the viscera is first to eliminate the toxin, and then to enhance the vitality of the viscera, so that the viscera is always in a perfect state.

Under normal circumstances, the lifespan of ordinary people is about 120 years old, but most ordinary people only live to be seventy or eighty years old before they die, and the long-lived ones are more than 100 years old.

This is because too many toxins accumulate in the body, which leads to the premature decline of visceral function and affects longevity.

However, when you reach the level of internal gang, you may use the qi to cleanse the internal organs, eliminate toxins, and increase the vitality of the internal organs, and it will not be a problem to live to the age of 120 without touching people.

If you often do things with people, you will be left with incurable dark wounds in your body, and you are likely to live shorter than ordinary people.

In short, the Neigang-level samurai is to cleanse the viscera and discharge all the toxins in the viscera from the body, so that the viscera is as clear and flawless as exquisite, and then it can be refined.

Of course, if a person has not swallowed grains since he was a child, but has been using Yuanjing to cultivate, then there will be almost no impurities and toxins in his body, and he can easily reach the peak of Neigang.

For example, the children of the Dayue royal family, when they were children, bathed and built a foundation with the spiritual liquid quenched by the elixir, and used Yuan Jing when they cultivated, keeping their bodies flawless and unblemished, and reaching the peak of the Neigang level at the age of eleven or twelve, which is a very normal thing.

However, except for the children of the Dayue royal family, even the Shangyang family, the first family in Shangyang County, does not have such a background, so that all the children of the family have used the spiritual liquid quenched by the elixir since they were children to bathe and build a foundation, and they all use Yuanjing when cultivating to keep their bodies flawless and unblemished.

At most, there are only a few people, and the successors who hope to take over the position of head of the family have such treatment.

After the cultivation was over, Zhou Chen took a shower, changed his clothes, and was relaxed.

Next, it is to quietly wait for the opening of the Ascension Conference.

Soon, five days passed in a blink of an eye!

"Boom!"

An incomparably loud, gold-cracked bell bell broke the silence of the early morning, stirring in Qingyun Temple, and many people's ears were buzzing, and there was a brief loss of deafness.

Immediately, many people turned their qi to protect their eardrums from being cracked.

When the bell rings, it means that the ascension meeting has begun.

"Let's go!"

In the courtyard of Qingyun Temple, many people rushed out in a hurry.

As soon as the bell rings, everyone must gather at the designated place, and if they do not arrive after the thirty-six bells ring, they will be directly disqualified from participating in the Ascension Conference.

Zhou Chen, Zhou Feng and Zhou Lei were like arrows from the string, shooting towards the outside of the courtyard.

Fortunately, on the last day, Zhou Lei successfully condensed his qi into a gang and reached the level of waigang.

Knock! knock! knock......

The high-pitched and loud bells reverberate.

There was an incomparably spacious square in the center of Qingyun Academy, and at this time, countless preparatory disciples gathered from all directions, and the number of people soon reached as many as 10,000 people.

"There are so many people, and in the end, only a hundred people can pass the trial selection, it's really cruel!"

"Most of these people have reached the Waigang level, and some geniuses have even reached the Neigang level, those of us who came from the small town probably have no hope, and they came here purely to accompany the prince to study. ”

"Alas, who says it's not, in some small cities and medium-sized cities, there are only seven or eight people who can reach the level of Waigang under the age of eighteen, which can be regarded as the top genius, but when they arrive in Shangyang City, they are reduced to ordinary goods. ”

"Hehe, it's just a meeting to ascend to the sky, and there is no difficulty for me. ”

“......”

More than 10,000 preparatory disciples kept muttering.

All kinds of voices came and went, and everyone's faces were also different.

The faces of the disciples from small cities and medium-sized cities were more sad.

As for those children of big city families, they are excited, expectant, and full of confidence.
