Reaching out to wipe the blood that overflowed from the corner of his mouth, Yang Yan stared at the front and turned into a substantial murderous aura, the heavy pressure like a mountain just now even shocked his internal organs, but the wound torn by the sword qi was not a big deal, and it could be repaired quickly.

Although he had almost no pressure outside of twenty zhang now, he could still only take four steps forward and couldn't resist, the murderous aura there turned into substance, it was too powerful, and the murderous aura he comprehended alone was not enough.

Yang Yan didn't think that his method was wrong, he was able to come here already showed that his method was correct, only by comprehending the murderous aura here, the law came out of the same origin, and formed some kind of echo, could the influence of the murderous aura on him be weakened, and then the influence of the sword qi would also be weakened.

After all, he didn't comprehend enough, after all, it was only a little more than a day since he began to comprehend, how much can he comprehend in such a short time?

If there is enough time, Yang Yan will continue to comprehend, and he may be able to pass the murderous qi in front, but he only has half a month, which is not enough at all, and the test will not only require him to pass the murderous qi, but also the stone wall, the source of the murderous qi and sword qi is it, and the difficulty will only be greater.

Yang Yan's murderous gaze flickered as he stared at the front, and his mind raced: "The murderous aura within twenty zhang is so powerful because it is so rich that it has turned into a substantial existence, compared to the murderous aura on the periphery, it is not only a quantitative change, but also a qualitative change." ”

"Up to now, the murderous aura comprehended by this prince is the same as the murderous aura on the periphery, and there is still an almost essential gap compared to the murderous aura inside, just like a group of guerrilla generals against an elite division commanded by a wise general, even if there are more of these guerrilla generals, they are just a rabble, and they will be defeated with one blow. ”

"If this prince wants to change this situation, he can no longer be a ranger, he must integrate all his forces to refine an elite, even if it is still incomparable, but it is no longer a vulnerable rabble. ”

Thinking of this, Yang Yan seemed to have a kind of enlightenment, and immediately sat down and began to further cultivate.

As Yang Yan settled, the murderous aura he emitted began to retract into his body and no longer release it, and the result was that the murderous aura that was originally equivalent to being dispersed was once again shrouded, enveloping Yang Yan in it, and even a lot of murderous aura poured into his body to destroy and erode.

In this regard, Yang Yan was not surprised or rejoiced, although he withdrew his murderous aura, it was not without murderous aura, but it was condensed in his body, although these invading murderous qi entered his body, although he was still killing, he was much more docile when he encountered his murderous aura.

In this way, Yang Yan was quite easy to refine, he combined the original murderous qi with the murderous qi that had just been refined, and then began to compress, from the size of a fist at the beginning to the size of an egg, and then to the size of a goose egg, and continued to compress.

It wasn't until a quarter of an hour later that this murderous aura had been compressed to the size of a grain of rice, shrinking by ninety percent and ninety, which was a world of difference compared to the original fist size, but the killing intent exuded had not weakened, but had increased several times, which was not the same.

It's as if a rabble of dozens of people has become an elite of no more than a few people, although the number is too small, but the strength has increased.

At this point, Yang Yan still did not stop, but continued to compress, the volume of the murderous aura the size of a grain of rice was still shrinking, until it was as thin as a hair, and it stopped compressing, at this time, it already had a trace of murderous aura within twenty zhang, and it was condensed a lot.

The murderous aura of the outside world did not dissipate because of the changes in his body, it still continued to invade Yang Yan's body, becoming nourishment, and after being refined by him, it was integrated into the hair-like murderous aura, and then compressed it vigorously, making the murderous aura more and more condensed, and the aura emitted became more and more terrifying.

In this way, the murderous aura that permeated Yang Yan poured into his body one after another, but it was as if he had been swallowed up in turn, cultivating that murderous aura and making it grow stronger and stronger.

Because this is just on the border of twenty zhang, the murderous aura in front of it is extremely rich, and the murderous aura consumed can be replenished at any time, and the murderous aura around Yang Yan's body has not decreased because of his devouring, but has maintained a certain concentration without obvious changes.

With the passage of time, Yang Yan absorbed more and more murderous energy, the volume of that murderous energy did not change, and the degree of condensation was constantly improving, but there was still a long way to go before it turned into substance.

Gradually, he was no longer satisfied with passive absorption, it was too slow.

The Heavenly Yang Sacred Law began to work in his body, and his body surface emitted a faint golden light, and even faintly seemed to appear as if there were extremely small and extremely small whirlpools that could not be seen by the naked eye, generating a powerful suction force that absorbed the energy of the surrounding space.

The foundation of martial arts cultivation is energy, and the universal space of heaven and earth vitality is the beginning of martial arts, the sages began to discover and use and absorb the energy, to create a variety of exercises, thus opening up a supreme road with the heavens, the development of martial arts began from this, now the system of the Nine Dragons Continent has been quite mature, and the heaven and earth vitality is the foundation of martial arts cultivation.

In addition to being absorbed by the martial artist to strengthen their own heaven and earth vitality, there are also other forms of energy between heaven and earth, which cannot become the basis of martial arts cultivation like the heaven and earth vitality, but after a long period of historical development, some great powers have found that although these energies cannot improve the realm, they can be used to enhance the strength of the martial arts, so there is also the theory of martial arts.

The exercises are used to absorb energy, and the murderous qi is essentially a kind of energy, which can also be absorbed by the exercises, but because the murderous qi belongs to the tyrannical type of energy, it is much more difficult to absorb, and the average martial artist does not dare to absorb it, and the murderous qi will destroy everything in the body after entering the body, and it will also erode the mind.

Yang Yan didn't have such concerns, not to mention that his weapon technique could quickly repair the damage caused by the murderous aura, the murderous aura he possessed alone had been very condensed after some cultivation, and the quality was already higher than that of the murderous aura in the outside world, and the murderous aura entering the body was easy to be subdued by him.

Suddenly, under the operation of the "Tianyang Holy Law", the murderous aura that was already pouring towards Yang Yan was absorbed by Yang Yan like a long whale absorbing water, and after some refining, it was integrated into his own murderous qi, making it more and more condensed, faintly turning into substance.

An hour later, in Yang Yan's body, a thin thread thinner than a hair lay there quietly, but it exuded a palpitating killing intent, which was the murderous aura that Yang Yan had condensed for an unknown number of times.

At this time, it has turned into substance, and it looks like an ordinary thin line, if it does not exude a strong killing intent, it is difficult to detect that it is a murderous aura condensed to the extreme.

This murderous aura can be regarded as done.

Yang Yan didn't stop there, he was still refining and condensing the murderous qi around Da Tun Te, refining and condensing, step by step, and half an hour later, another murderous aura was condensed and formed by Yang Yan.

This process is constantly repeated, and in the next half a day, there are several murderous qi condensed and formed, fortunately, this is in the border area of twenty zhang, and the murderous qi is endless, if you retreat more than ten or twenty zhang, even if you absorb all the murderous qi there, you can't condense so much substantive murderous qi.

A day later, Yang Yan opened his eyes, and there was a blood-colored light blooming in the space, flashing with an astonishing killing intent, and then disappeared, and now no less than thirty murderous qi had been condensed in his body, and if it broke out, the power would definitely not be underestimated.

Feeling the condensation of a murderous aura, Yang Yan stood up, his eyes stared ahead, full of fighting spirit, this time, he would definitely not take half a step back!

"Boom!"

Without hesitation, Yang Yan took one step, not surprisingly, the fierce pressure invaded, killing, bloodthirsty, Yang Yan's complexion remained unchanged, mobilizing a murderous aura, and suddenly the pressure plummeted, and this step fell steadily.

"Boom!"

The second step fell, the murderous aura was twice as strong, and the pressure also increased, and Yang Yan once again mobilized a murderous aura.

"Knock! knock......"

Yang Yan stepped out continuously, and with each step, the pressure increased by two times, and he mobilized one more murderous aura to resist.

In less than a quarter of an hour, Yang Yan walked ten zhang away, and there were still ten zhang away from the stone wall, but Yang Yan did not rush forward, this time and again, he vaguely knew that every ten zhang in this area was a dividing line, and the increase was getting bigger and bigger, twenty zhang to ten zhang was a double increase, which was likely to be three or four times in front.

The killing and bloodthirsty aura rushed to the face, making the cold hair explode, and the vertical and horizontal sword qi actually had a feeling of being cut off, and faintly blood appeared on the surface of the skin, forming blood-colored traces.

"This sword qi is so strong!" Yang Yan felt his own situation and exclaimed, when he arrived here, I am afraid that it will be difficult to deal with not only the murderous aura, but also the sword qi is deadly, if you don't release the sword momentum to resist, I'm afraid it won't work.

After thinking for a moment, Yang Yan suddenly sat up on the spot, facing more difficult challenges, he had to deal with them in the best condition, and after walking the distance of ten zhang just now, the murderous qi he had finally condensed had already consumed a small half, and he had to condense it again.

It wasn't until a day later that Yang Yan opened his eyes again, the murderous aura condensation degree of the land of ten zhang is not comparable to the murderous aura of twenty zhang, it can be said that it has gone up a notch in terms of quality, and there is a huge pressure, he also needs to consume some murderous qi to compete, and the time it takes is naturally longer, but because of this, the murderous aura he condensed this time is also stronger and of higher quality.

Exhaling lightly, Yang Yan was about to challenge the land of ten zhang, but suddenly found that he could already see some patterns on the stone wall, although there was a strong murderous aura and fierce sword aura blocking his vision, but he did see the pattern on the far right.

Yang Yan and the stone wall were still ten zhang apart, but when he looked at the stone wall, it was as if he was facing the stone wall, the pattern was full of fierce sword will and strong killing will, and the sword qi and murderous aura that diffused at will formed this terrifying area, which was difficult to resist and difficult to move.

With such a pattern, it is almost impossible to look at it directly, even Yang Yan felt a tingling pain in his eyes, and the terrifying will to kill and kendo came like a tide, to crush him, in just a moment, Yang Yan's back was already soaked, his face was pale, and he could not bear such a terrifying pressure, so he quickly turned his gaze away.

In this short moment of vision, Yang Yan only saw that the pattern was a word.

"Kill"!
