"This set of sword techniques is simply violent when it falls into Yue Yun's hands!" Situ Yu grinned, with a look of emotion.

Immediately, I couldn't hold back my curiosity, and under the urging of a strong desire, I began to understand the mystery of this set of knife techniques in detail.

Gradually, Situ Yu almost entered the realm of forgetting things and me, and even forgot the life and death process that happened at night, which unconsciously made his mental training more and more firm.

There was hardly anything that could affect him and shake his courage.

Time passed in a hurry, and Situ Yu began to operate his spiritual power according to the mental method knife technique on the lore knife technique, becoming more and more proficient, and faintly seemed to really feel the murderous aura on his body.

Although Yue Yuncao learned the lore sword technique, but what he practiced was only the sword technique, but he did not learn the knife technique, but Situ Yu was different, Situ Yu didn't know how many people he had killed, and in addition to the environment in which he grew up and all the circumstances, he had already been covered with murderous aura, even the general who fought most of the generals could not compare with him.

Therefore, Situ Yu chose to cultivate the sword technique first, and after truly understanding the essence of the sword technique, he was practicing the knife technique, but with the help of his own heritage, Situ Yu cultivated the knife technique very smoothly.

Unconsciously, Situ Yu's body sitting cross-legged on the ground seemed to emit faint cyan light, and the temperature of the entire room was beginning to drop extremely much.

Later, the faint cyan streamer on Situ Yu's body became more and more serious, and the tables and walls in the surrounding rooms were faintly filled with a layer of frost.

The temperature reached unimaginably cold levels.

This cultivation is one day and one night.

Situ Yu also completely forgot the time, because all his mind was immersed in that wonderful feeling, and he felt that his whole body was like a huge treasure trove, containing many mysterious liliang that he didn't know.

And the murderous aura is just one of them, according to the knife technique on the lore knife method, Situ Yu has gradually been able to manipulate the murderous aura on his body, the cold, formless and qualitative existence.

However, at this moment, Situ Yu's eyebrows suddenly furrowed, and he felt that the black aura that the mysterious dagger in his dantian had turned into had actually begun to move, as if it had also moved with the sword technique of the Killing Sword Technique.

"This ...... Could it be that the sword technique of the Killing Sword Technique can also manipulate this mysterious black aura?" Situ Yu couldn't help but think in amazement in his heart, and he couldn't help but tremble in surprise when he thought of this possibility.

Then he couldn't help but try to urge the black aura in the dantian according to the knife technique, and sure enough, as he expected, the black aura actually began to flow with his control, but no matter how hard Situ Yu tried, the black aura that could be urged was extremely limited, not even one-tenth.

But even so, less than a tenth of the black aura was already very terrifying, and the aura contained in it was many times more powerful than the murderous aura in his whole body combined, especially the aura of death was actually similar to the murderous aura.

After feeling the terrifying and powerful liliang, Situ Yu became more and more excited, and a trace of strong belief rose in his heart at the same time, gritting his teeth and concentrating on running the knife technique with all his might, and a gradually strange scene appeared, Situ Yu was surprised to find that with the black aura in the dantian began to gradually burst out with violent light, more and more, when the aura fluctuations became more and more intense, all the murderous aura in his body actually began to be absorbed by it, and it was completely integrated with it in an instant, and it also became a part of the black aura。

Situ Yu was terrified, but when he tried to control that black aura again, he found that the amount he could control had increased by one point, and it was enough to control one-tenth of all the black aura.

"Strange, really strange, what is the origin of this dagger, it is so weird, and the black aura that this dagger turns into is really terrifying, if I can use all of this liliang, how strong will it be?" Situ Yu opened his eyes slightly, and muttered with a look of surprise, thinking of this, he couldn't help but want to try it again.

Sinking into his mind again, Situ Yu controlled the black aura all over his body, and suddenly vented that aura at the same time.

Suddenly, everything in the entire room was almost visible to the naked eye, the walls and the ground were filled with a layer of ice crystals, Situ Yu's whole person seemed to have become a little taller, his whole body was dressed without wind, and his long hair stood up and sprinkled behind him, and a terrible cold aura of death spread out from his whole body, filling the entire room.

"Drink ......" Situ Yu suddenly shouted angrily, and this breath reached its peak in an instant.

"Bang ......"

The teacups and kettles on the table were the first to burst open when they couldn't withstand such a strong pressure, followed by those stools and tables also exploded, and even Situ Yu's bed collapsed and exploded into powder......

There was a loud bang, dizziness, and the whole mansion trembled.

Heaven and earth returned to calm, after Situ Yu restrained that breath, he looked around and was surprised to find that everything in the entire room had turned into powder, and on the wall, terrible cracks appeared on the ground, like spider webs, covering the entire room, especially the wall as if it might collapse at any time.

"This ......" Situ Yu was absolutely stunned, just now he just wanted to try how strong this liliang was, so he didn't control it specifically, but released it completely and absolutely, he didn't expect Zuihou to cause such a big impact.

"Amazing, too powerful, although I didn't know that this black aura weishenme could be fused with murderous qi, but the liliang that burst out has completely surpassed my current Heaven Swallowing Spell and Xuan Ming Duel. Situ Yu sighed excitedly.

Then Situ Yu condensed the mysterious dagger in his body, held it in his hand and looked at the ordinary dagger that was pitch black in his heart, and tried to use the knife technique of the lore knife technique he had just learned to control the dagger to swing it a few times at will, and in an instant, the dagger burst out with a violent black light, and most of the black aura filled the entire room, swallowing and drowning the morning light that shot down outside, and the cold breath of death seemed to be completely integrated with Situ Yu.

"Sneer......"

Several sounds of breaking the air sounded, and Situ Yu could faintly feel that the air seemed to be about to be cut, and the power was several times greater than before.

"Okay, with my current strength, I'm afraid that even against the seventh-level master of the Upper Spirit Sect, I have a complete chance of winning. Situ Yu shouted in surprise and put away the mysterious dagger again.

He glanced at the surrounding environment with a wry smile, and couldn't help but shake his head secretly, he didn't expect that he would have such an opportunity, and he had obtained such a big benefit in vain, and it was simply worth it to go to the City Lord's Mansion this time, not only did he get three million high-level rewards, but he also got a lore sword technique and thus his strength increased greatly.

"Since this Liliang is so mysterious, far beyond the Heaven Devouring Spell and the Xuan Ming Decision, I might as well use it to open up the few remaining acupuncture points of Zuihou. Situ Yu had an idea, and couldn't help but secretly think that he urgently needed to improve his strength now, even if Liliang increased, the realm still did not break through, and it was never superior.

Thinking of this, Situ Yu was unwilling to hesitate for a moment, so he hurriedly changed rooms and began to cultivate.

After a day and a night of cultivation, Situ Yu had basically successfully mastered the sword technique of the Killing Sword Technique, and by chance, he not only learned to control his own murderous aura, but also fused the murderous aura with that black aura to become more powerful.

This time, Situ Yu cultivated not to continue to cultivate the Killing Sword Technique, but to break through the realm.

After a series of assassinations, his strength had almost reached the peak realm of the fourth level of the Spirit Sect, and he had faintly reached a critical point.

Situ Yu sat cross-legged on the ground, his heart facing the sky, his eyes slightly closed, and his breath was calm.

Although the Heaven Swallowing Spell and the Xuan Ming Decisive are almost at a critical point, they have not yet reached it, so it is not yet the time to break through, and it still needs a period of brewing and accumulation, and now Situ Yu is already hungry and wants to impact the fifth level of the Spirit Sect, so he uses the black aura he has just obtained to stimulate the two peerless ** and forcibly impact the pass.

The Heaven Swallowing Spell was originally transmitted from ancient times, and it was a real ancient secret method.

There is a great difference between the ancient ** and the current law.

Generally, ** is to immediately concentrate on the qi, and then through each of the different and prescribed fixed meridian circulation routes and practice and operation, but because of this, it also invisibly limits the capacity of spiritual power at each level, because the human meridians are the most fragile, and the strength and weight of the spiritual power experienced are also limited, and the strength can only continue to improve the realm, so that their own meridians become stronger and stronger in order to be able to accommodate more spiritual power, so as to maximize the burst of due strength. What's more important is that the usual ** can only store spiritual power in the dantian, and under the influence of the realm, the spiritual power contained in the dantian is also very limited, only the stronger the strength, the spiritual power can be condensed and purified, compressed, so that the volume of the aura becomes smaller to accommodate more aura.

However, the Heaven Swallowing Spell is different, in addition to storing spiritual power in the dantian, the Heaven Swallowing Spell can also open up the eight veins of the Qi Jing to store the spiritual power in the eight veins of the Qi Jing, and there is no fixed pattern for the meridian route of the Heaven Swallowing Spell at the same time, that is to say, Situ Yu can burst out of spiritual power through any meridian at any time and anywhere, so that not only can he store more spiritual power than the spirit of the same level, but also can quickly generate spiritual power, and of course it will greatly increase the advantage when fighting.
