Xia Bo concentrated on controlling the vitality in his body to shrink little by little, making the vitality density thicker and thicker, and even a hint of liquid. The sound of jumping up and down in the sea of air.

His sea of qi is solid, and he is allowed to be impacted.

That's not enough, though!

Unhurriedly and impatiently, he controlled the vitality, condensed little by little, so that the vitality continued to compress and condense, and after dozens of efforts, those liquid vitality finally had a trace of solidification.

Xia Bo couldn't help but exhale lightly, although the condensation yuan core was not as good as the condensing yuan dan, it was also quite thrilling, and several times during the period, he almost couldn't control the yuan qi rioting.

"Wealth and danger are in danger, and we are finally going to succeed. Just when Xia Bo was very happy, night fell, the stars were shining, and the step of condensing the Yuan Core was about to be completed.

It took him nearly a day, and his spirit was a little tired.

And at this moment, the silver light spot hidden in the original body was restless, Xia Boqiang calmed down, and suppressed it with spiritual power with both hearts.

But the suppression was ineffective, and those silver points of light that stayed in his body separated some energy and turned into a ray of light, like small worms climbing up along his meridians.

"Damn!" Xia Bo suddenly felt that his distraction, the condensed Yuan Core was actually a bit of a riot.

If there is a riot, not only will the previous achievements be lost, but it may even explode the sea of air.

That's what worries him the most.

At this time, he was worried that it would be useless, so Xia Bo simply withdrew his control of the silver point of light and reinvested himself in the condensation elemental core.

With this suppression, the Yuan Core condensed again, and without waiting for Xia Bo to breathe a sigh of relief, those silver rays of light rushed into the sea of qi, full of spirituality, and after discovering the Yuan Core, they actually swarmed like a treasure, making him a little scrambling.

Then, he thought about the many benefits that the Origin Dao Sutra had brought to him, and then he was relieved, and continued to condense the Yuan Core according to the steps, allowing the silver light point to enter, and his state of mind was improved, making him fully trust the silver light point.

Under the impact of the silver light spots, sure enough, the originally depleted vitality was immediately filled, which greatly lifted Xia Bo's spirits.

"Heavenly Dao is forty-nine, I am fifty, the three realms are free to travel, and the five elements are outside. The root of the Tao, break one point and two ......" a mantra slowly flowed through his heart, and this mantra of the Origin Dao Sutra was like five thunderbolts, which made Xia Bo's spirit greatly boosted and his confidence doubled.

Xia Bo's understanding of the Origin Dao Sutra has been raised to a higher level, and the power of faith in the original sea of knowledge is immovable, but under the stimulation of this silver point of light, it ripples in the microwave, completely blending into the sea of knowledge, forming a lake of spiritual power.

Xia Bo immediately took a big gulp, and after a while, his spirit was greatly lifted, and he manipulated his spiritual power to turn into a spiritual blade, splitting the Yuan Core that had just been condensed into two and turning it into two smaller Yuan Nuclei.

This step is extremely dangerous, and if it is not properly controlled, the compressed energy in the nucleus will burst like explosives.

Carefully controlling the division of the Yuan Nucleus, and the silver rays of light were like great tonic medicines, as soon as they entered the Yuan Nucleus, they quickly wrapped the cutting place, making the Yuan Qi squeezed and condensed again.

There was no time to get excited, Xia Bo hurriedly calmed his mind, and divided his spiritual power into two and condensed two yuan cores at the same time, dozens of times of refining and condensing, and the two eyeball-sized yuan cores slowly formed, like two silver stars shining in the sea of silent whirlwind.

With a big gulp, a large stream of air rushed in, turning into a stream of yuan force under the transformation of the yuan core, stored in the sea of qi, and allowed Xia Bo to mobilize.

After settling down, he used these yuan forces to forge and temper the flesh and skin of the body again, so that the body was constantly strengthened.

After half an hour, the quenching is complete!

Xia Bo only felt a powerful feeling permeating his mind, this is the Yuan Force filling the body with tenacity and pulling a force and the whole body, and opened his eyes: "I didn't expect to be able to condense two Yuan Nuclei, I now feel that the power is infinite, and I can move a hill." ”

After estimating, it was an unexpected joy to condense two yuan cores this time, and if it exploded completely, it could release the power of nine people, which he did not expect in advance. Originally, he thought that if the condensation of the Yuan Core was successful, it would be good to have the strength of forty-five people, but now it has doubled, which makes him extremely happy.

The strength of ninety people is equivalent to the strength of the early stage of the ordinary Jindan Realm, and the quality of this kind of Yuan Force can be called demonic.

Moreover, the flesh and blood have been forged, the impurities and fat have been evaporated, and the body is as solid as steel.

"The strength of only ninety people, the gap with Xia Yuantong's imagination is not small!" For this kind of effect, Xia Bo is still not satisfied.

Under such a toss, Xia Bo's spiritual power in the sea was a little lacking, and he was about to form his mental power, but now he basically recovered the situation before the spiritual power infusion: "It seems that the path of the spirit master is indeed not easy to walk." ”

"If you want to turn the pool of spiritual power into a lake of spiritual power, or even a river and a sea, I don't know when and when it will be!" Xia Bo felt a little melancholy, after all, it was difficult for Yuan Li to cultivate spiritual power: "If you want to achieve something in spiritual power cultivation, you must find a special spiritual cultivation decision." ”

"It's too slow to just rely on comprehending the Origin Dao Sutra and meditating and meditating!" Xia Bo secretly pondered, once he broke through the spirit master, walking, eating, thinking, sleeping, etc., as long as the divine consciousness existed, he could cultivate spiritual power, but now, he had to concentrate on meditation and meditate.

Shaking his head, he was also a little tired at the end of the day, and now he needs to eat a big meal and have a good rest to recuperate.

After a night's rest, Xia Bo was in good spirits.

With a slight fist, the strength suddenly increased.

The next step is to study the big yin and yang boxing, Xia Bo first comprehended the formula, figured out the changes in the moves, simulated the Yuan Li Yun route and sat down cross-legged, concentrated and closed his eyes, and the big yin and yang fist mantra came to his heart: "Yin and Yang Tai Chi follow each other, and the movement and stillness are pushed by the virtual and real;

"The Great Yin and Yang Fist focuses on how to exert force, so that the Yuan Force secretly combines the way of Yin and Yang, which is indeed a little difficult for ordinary people. Shabo muttered to himself.

"Yin and Yang are mutually reinforcing things, contrary to common sense, ethereal, how to mix and use, fortunately, I condensed into two yuan cores, this problem will naturally be solved. "The more Xia Bo studied, the more he felt that this Great Yin Yang Fist was broad and profound, and it was not comparable to ordinary ground-level beginner-level martial arts.

This martial arts advocates the way of Tai Chi Yin and Yang, paying attention to the stillness in movement, the reality in the void, the combination of rigidity and softness, the suppression of the tone and frustration, the bending and stretching, the back and forth, the retraction and relaxation!

This is an innovative theory in the martial arts, which is simply unheard of, and at the same time it is in line with the truth!

The first type of Yin Yang Fist Yin Yang Kill, this is a big killing move, once it is used, it is extremely powerful.

In the formula, it is said that two Yuan forces should be divided successively, one yin and one yang are mixed with each other, and the yang mainly attacks the yin assassination, and the power of the two attacks at the same time is suddenly doubled.

After understanding this, Xia Bo's heart moved, and he began to deduce the moves of the Great Yin Yang Fist.

After Zhihai deduced the first form of the Great Yin Yang Fist dozens of times, he had already understood and mastered everything.

However, this is only a theoretical mastery, and it cannot make up for the actual application, and in order to use the Yin and Yang Destruction Killing to understand it thoroughly, you have to cultivate it over and over again.

This Great Yin Yang Fist is demanding, extremely dangerous to cast, and can cause a big explosion if you don't pay attention.

Rao is Xia Bo can use two things, and he doesn't dare to use it easily in his own yard, in case it causes an explosion, the gains outweigh the losses, so he fixed his eyes on the barren mountains outside the city.

Tens of thousands of miles of barren mountains, birds are tired and die halfway, saying that the range of barren mountains is that even birds can't fly over.

It is said that on the other side of the mountain is another world, where there are savage tribes of savages, who drink the blood of Maoru and are thirsty for killing and warlike.

However, this is just a rumor, because no one has ever been there.

Barren mountains are made up of thousands of giant mountains, with numerous cliffs and abundant resources.

Among them, there are spiritual herbs and fierce demon beasts, most of the people in Yuancheng are mining resources on the periphery, and few people go deep into it, because the deeper it is, the more ferocious the demon beasts are.

There are even some murderous king demon beasts in the depths, monopolizing a mountain to claim the king's hegemony, even the strong people of the Jindan Realm do not dare to go deep alone, they must form a team.

It is even rumored that in the depths of the barren mountains, some demon beasts with great wisdom can be transformed into human form when they reach the transformation stage, and their cultivation is so deep that they are not opponents in the later stages of the Jindan period, only the strong power of the Yuanying Realm can compete with them.

Because the inner world of the barren mountain is not as simple as it seems, but there is something different!

In an open space on the outskirts of the barren mountain, a figure of fitness fell heavily from mid-air.

With a thud, the ground smashed into a deep pit.

Xia Bo ran up and down all the way, very vaguely avoiding the eyes of ordinary people, choosing a quiet place, looking around, and nodded with satisfaction.

This place is deep on the outskirts of the barren mountain, and very few people have come here anymore, which allows him to study the Great Yin and Yang Fist with confidence.

The first type of yin and yang killing, which requires the combination of dual-core yuan force, one positive and one negative, according to the deduction moves, calm and relaxed, and the mind drives the yuan force to operate, one left and one right are handed out layer by layer along the arm.

Two completely different Yuan forces, as soon as they touched his hand, they exploded, no less powerful than a bomb, enough to blow up a boulder to pieces, fortunately, the body was strong enough, and the Yuan Qi explosion did not cause any damage, but only made him a little disgraced.

"This failure is due to a lack of concentration, and the uneven extraction of the dual-core Yuan Force caused the Yuan Force to explode!" Xia Bo encouraged the Yuan Force of his whole body, shook off the dust on his body, and continued to figure it out, summing up the cause of the first failure.

The dual-core yuan force condensed again, but it had already dispersed before it could be blended, like a balloon bursting, Xia Bo corrected the reason again: "This is caused by the irregular movement of the exercises. ”

The dozens of failures in a row are traceable, which makes Xia Bo more and more aware in his heart, faintly touches the true meaning, closes his eyes and ponders for a moment.

"Yin and Yang Kill!" Suddenly, Xia Bo's eyes opened suddenly, and he shouted, clenched his fists with both hands to control the Yuan Force, and then pushed forward suddenly.

Suddenly, two completely different Yuan forces shot out from the fist blade, condensing into a purple giant fist the size of a zhang in the air, and smashed forward.

"Thunder belongs to yang, electricity belongs to yin, this move Yin and Yang Killing actually implies the power of thunder and lightning, it is definitely a big killing move, and it is really much more powerful than the Thrilling Fist. Xia Bo was surprised and delighted, and sighed secretly at the power of the first form of the Great Yin Yang Fist, with which he was confident that he could compete with the existence of the early stage of the Jindan Realm.

Although the Great Yin Yang Fist is difficult to cultivate, once the cultivation is successful, its power is extremely strong, it can be called against the sky, he is now just a fourth-layer martial artist who cultivates qi, once he breaks through the fifth layer, it is not impossible to defeat the powerhouse of the ordinary Jindan realm.

He also figured out the experience of the Great Yin and Yang Fist, made it comprehensible, and skillfully turned the surrounding trees into a ruin over and over again, until the dual-core inner yuan force was somewhat exhausted and mentally exhausted, Xia Bo did not stop.

He used the Qi Induction Technique to the extreme, devouring the aura of heaven and earth wantonly, and under the high rotation of the Yuan Nucleus, half an hour later, the Yuan Force in the Qi Sea was filled again.

Now that his body has been tempered, he is extremely strong everywhere, and he is not afraid of the riots and impacts of the Yuan Force at all, so he recovers extremely quickly.

The Yuan Force was swung up, and the whole body was cleaned again.

Shabo smiled with satisfaction and ran away, his speed like a cheetah, agile as an ape, and light as a butterfly.

When encountering tall rocks, they will be left far behind when they rise and fall, and this ability makes some wild boars and black bears avoid them far away.

After a while, there were traces of people in the jungle, all of whom went up the mountain to pick elixir.

In order not to be too shocking, Xia Bo slowed down.

"Hey, there's a situation ahead!" Xia Bo had already noticed the front between jumps, because his mental power was much stronger when he knew the sea, and before he got close, there was a group of people gathered in front of him, and they were making a lot of noise.

Stopping, Shabo cautiously moved forward.

Although his cultivation has increased greatly, after all, he is only a "little person" who practices the Qi Realm, and when he encounters some Jindan Realm powerhouses, he still has some rat traps.

After getting closer, Xia Bo quietly observed the situation, it was two people and horses confronting each other, one was Xia Mengdie, whom he had seen not long ago, her smooth little hand held a fiery red spiritual horse clover, each leaf was in the shape of a flame, this was the Red Flame Grass.

Beside her was a girl of the same age, fifteen or sixteen years old, with good looks and figure, it was her personal maidservant, Xia Qiaolian.

On the other side are several teenagers, dressed brightly and with extraordinary bearing, but their faces are relatively unfamiliar, all of them are a little fierce and vicious, and one of them is Xia Lei.

"Little Sister Mengdie, for your brother Xia Lei's sake, I won't treat you badly, so I'll exchange ten taels of gold in exchange, how about it?" The young man in brocade took out a piece of gold from his arms, and he was about to take the Red Flame Grass from Xia Mengdie's hand, if he obtained this Red Flame Grass, his Great Flame Palm could be gradually perfected and his power would be doubled.

Xia Mengdie pursed her lips lightly, held the red flame grass tightly and took a few steps back, tears in her eyes, and her silver teeth bit lightly: "Wang Yan, you deceive people too much, this red flame grass is what I have worked so hard to get, and it is used for my father to keep out the cold!"

A red flame grass is worth a lot of money, and if it is brought to a large auction, it can be sold for at least a thousand taels of gold.

Wang Yan actually wanted to exchange it for only ten taels of gold, this is simply a blatant robbery!

Wang Yan's face was not good, and his eyes shining when he looked at the young man beside him: "Xia Lei, what do you say about this?"

Xia Lei nodded, then took a step forward and scolded loudly: "Xia Mengdie, you are a foreign descendant of the family, and Wang Yan is the son of the Wang family, and his identity is much more noble than you!"

Besides, my Xia family has always been good friends with the Wang family, since Wang Yan Gongzi wants this red flame grass, you should hand it over obediently, and it will be regarded as a contribution to the family!"

The Wang family he said is also a big family in Yuancheng, with a strong family, which is higher than the Xia family.

Xia Hai and this Wang Yan have always been good friends, and they often spend time drinking together, and they have the atmosphere of fox friends and dogs.

"Miss, in my opinion, let's give the Red Flame Grass to Wang Gongzi, this is a good opportunity to make friends!" Xia Qiaolian leaned over Xia Mengdie's ear and whispered.

Xia Mengdie glared at the latter, then turned her head and said, "Young Master Xia Lei, this Red Flame Grass is also of great use to me, my father still has Yin Qi in his body, and this Red Flame Grass is just used to heal!"

After listening to the conversation, Xia Bo secretly analyzed, it seems that this Xia Qiaolian must have been bought by Xia Hai and others to monitor Xia Mengdie.

Otherwise, as soon as the red flame grass was mined, Wang Yan and others knew about it and hurried over.
