In the battle with the Demon Emperor, Xiao Yun was seriously injured, and the bones of his whole body were almost scattered, but in the end, with the help of the innate suppression of the demon head by the Zixiao Tribulation Thunder and the Heavenly Tribulation, he still slaughtered a Demon Emperor, if this is spread, no matter what method he uses, he can use the realm of heaven and man to slaughter a Demon Emperor who has almost reached the peak, it will definitely shock the entire Three Thousand Worlds.

Of course, Xiao Yun wouldn't care about this, what he cared about was the Demon Emperor's Demon Crystal, the Demon King's Demon Crystal was of great help to him, making his cultivation and divine soul have increased greatly, and the Demon Emperor's Demon Crystal contained the mystery of the law, and the energy in it was even more terrifying, just a moment for him to fully recover.

As for the Heavenly Tribulation of the Four Heavens, for Xiao Yun in his heyday, there would not be any difficulty, and it would be difficult for him to be shaken at all by the Thunder Tribulation and the Heart Demon Tribulation.

After the end of the catastrophe, Xiao Yun quickly left that place and found a secret place, planning to refine the Demon Emperor's Demon Crystal, Xiao Yun knew that even if the quality of his True Yuan almost surpassed the divine power, refining that Demon Crystal was not so easy, after all, the Demon Emperor was already equivalent to a true god, and the power of the law was bred in the Demon Crystal, Xiao Yun's current realm, it was almost impossible to comprehend the law, and he could only use the refining of the Demon Crystal to peek slightly, which would also be of great benefit to his future martial arts path.

Sitting cross-legged, Xiao Yun quietly looked at the colorful magic crystal in his hand, his eyes showed a hint of joy, although this magic crystal was not as good as the one he got when he first came to refine the demon abyss, after all, that magic crystal was infected with the power of the world, and the mystery was endless, but the huge energy contained in it also made Xiao Yun feel a strong pressure.

"I don't know if my cultivation can go further after refining it, with my strength at this time, I can still deal with the early stage of the True God head-on, but if it is a sneak attack, with the power of Qianzhong Mountain and Xuanguang Palace, I can completely kill the strong people in the early stage of the True God. ”

Xiao Yun muttered to himself in his heart, holding the magic crystal in the palm of his hand, his eyes were slightly closed, and the true yuan in his body began to surge, constantly absorbing the energy in the magic crystal and inhaling it into his body for refining.

At the moment when the magic crystal energy entered his body, Xiao Yun felt that an incomparably pure power poured into his body, and it was frantically mixed with his true yuan, making the true yuan in his whole body seem to have received some kind of strong summoning, and it directly became extremely violent, running wildly in his meridians, giving him the illusion that he was about to explode.

At the same time, he also felt that there was also an evil aura, full of murderous emotions such as killing, bloodthirsty, dark, evil, and other endless negative emotions, which directly passed through his meridians and rushed into the sea of divine soul consciousness.

"Kill!"

Xiao Yun's eyes directly became red, and a violent killing intent was involuntarily released from his body, at this moment, he just wanted to kill as much as he wanted, he just wanted to devour everything and turn it into his own strength, and the clothes on his body were directly shattered by the violent momentum, and even the cave where he was hiding began to shake slowly as if there had been an earthquake.

The countless demons around were originally fighting and devouring each other, but at the moment when Xiao Yun's aura exploded, all the demons suddenly roared, and fled from this place frantically, not daring to stay for a moment, so that this area turned into a vacuum in just a moment, and no demons existed.

Xiao Yun was still careless, he had been in this demon refining abyss for more than ten years, he had long known that because the Demon Emperor was already equivalent to a true god powerhouse, although he could not use the power of the law like a normal intelligent being, but the magic crystal had already begun to give birth to the law, once the Demon Emperor fell, the magic crystal would inevitably be contaminated with the kind of unjust qi when the Demon Emperor fell, with the help of the power of the law, the person who refined the Demon Emperor's magic crystal, the strong person below the realm of the true god, it was difficult to resist this erosion.

Therefore, although the benefits of refining the Demon Emperor Demon Crystal are great, and it is even possible to obtain some strange abilities or supernatural powers from it, but those who really dare to do so are all true god powerhouses, and the strength of the Demon Emperor is extraordinary, and the number is very small, most of them exist in some dangerous forbidden places, and the strong below the true god are not opponents, how can they get the Demon Emperor Demon Crystal, like Xiao Yun, who kills the Demon Emperor with the help of external forces without being a true god, it can be said that there are very few, almost non-existent.

He underestimated the strength of the unjust qi in the Demon Emperor's Demon Crystal, and for a while his mind was confused, and even above the Yuan Shen, he was covered with a layer of gray, and all kinds of negative emotions poured in, making the killing intent in his heart even stronger, and the whole person had a sign of being about to demonize.

"I ...... Be...... Shaw...... Cloud...... It's just a demonic thought, and you want to mess with my mind, get out of here!"

At this moment, Xiao Yun's body suddenly had another breath rising, it was a wanton wild, unrestrained, vertical and horizontal meaning, it was the intention he comprehended from the endless mountains and seas under the spiritual pool, that is, demonic will.

Fundamentally speaking, the aura of the demon head in this demon refining abyss is also a kind of demonic intent, but it is not pure, because these demons only know how to kill and devour, even if they reach the level of the demon emperor, they can't change this ferocious nature, and they can't really comprehend the true demon path that is unhindered and rampant, so this kind of demonic intent is not pure.

And in the endless mountains and seas, the demon under the spirit pool gave Xiao Yun a feeling of the purest demonic path, as if it was the origin of the demonic path in the world and the destination of all demonic paths.

At the moment when this demonic intent erupted, the manic, bloodthirsty emotion retreated directly as if he had met the king's minion, and then frantically poured into the demonic intent, at this time, it can be seen that the blood light on Xiao Yun's body gradually disappeared, and above the primordial spirit, the gray thing gradually disappeared, and his eyes also returned to clarity, but his face was still a little hideous.

Because, that demonic intent is getting stronger and stronger, and there is a tendency to replace his own will and erase his martial arts, which is not to say that Xiao Yun's soul will be wiped out, but to turn him into a demonic monk and erase his martial will.

Xiao Yun will never allow this kind of thing to happen, his martial arts are fused with the demon dao, but he must not let the demon dao be swayed, he is the master of the martial arts, and he is the master of the demon dao, how can he let this demon dao dominate.

"Here, I'm the master!"

Xiao Yun snorted coldly, the Yuan Shen Giant pinched the trick with both hands, and the "Innate Phaseless Killing Divine Dao" in his body suddenly ran wildly, quickly devouring that demonic intent, turning it into the nutrients of this martial arts technique, so that the "Congenital Phaseless Killing Divine Dao" finally began to evolve again, and Xiao Yun's martial arts gradually took the initiative, allowing him to deduce this technique while refining the magic crystal.

And the magic crystal in his hand emitted a Dao Dao black light, and faintly, in that black light, there were Dao runes that appeared, which were constantly torn apart and reorganized, and finally turned into strange runes, which were imprinted in Xiao Yun's primordial spirit.

However, at this time, Xiao Yun didn't pay attention to this, but was concentrating on deducing "Innate Phaseless Killing Divine Dao", this is his foundation, and it is his reliance to compete in the Three Thousand Worlds in the future and climb to the pinnacle of martial arts.

In the sea of divine soul consciousness, the huge chain of order was manifested again, and the powerful power of demonic thoughts seemed to have turned into nourishment and was integrated into the chain of order, and the original fifty percent of the order divine training began to merge again, and even more Taoist divine breath was absorbed from the Demon Emperor's magic crystal, integrated into the order divine training, Xiao Yun could clearly feel that it was the power of the law bred in the magic crystal.

The power of the laws of one by one was integrated into the chain of order, although for Xiao Yun, the power of the laws bred by this magic crystal was insignificant, but it could also be the introduction for him to deduce the exercises, allowing him to gradually improve the "Innate Phaseless Killing Divine Dao", of course, what he is perfecting now is just the framework of this exercise, after all, his cultivation is still too low, his vision is not enough, and the level of the exercises he creates will not exceed the limit of his cultivation.

When Xiao Yun was refining the Demon Emperor Crystal and deducing the martial arts exercises, hundreds of thousands of miles away, the army of Taijing City finally dispatched and launched a fierce attack on the fortress on the periphery of Shangyuan City, a big battle lasted for three days and three nights, although Shangyuan City relied on a strong defense to resist the attack of Taijing City, but it was also a heavy loss, of course, as an attacking party, Taijing City was not much better.

On the second day of the war between the two major cities, the army of Guangguan City was dispatched, directly attacking the red stone fortress of Shangyuan City, and in one fell swoop, the area of 200,000 li near Guangguan City was included in the territory of Guangguan City, and Qingfu City also sent troops to take the Luohua Fortress of Shangyuan City, occupying 300,000 li of territory.

It can be said that on the bright side, the strength of Shangyuan City has fallen from the previous parallel with Taijing City to the weakest side of the four major cities, and it is surrounded by the three major cities, it is almost foreseeable that if Shangyuan City has no aftermove, it will not be long before Shangyuan City will be captured by the three cities and will be divided and eaten.

But what makes people puzzled is that even if the battle situation is so unfavorable, Shangyuan City is still extremely tough, without any intention of compromise, and even Yuan Wushuang has not been punished in any way, this situation is very abnormal, even if Yuan Wushuang is a true god mid-stage, but Shangyuan City is not the only one who is a true god mid-stage powerhouse, and he has caused so much trouble to Shangyuan City, and no one has gone to him to ask for guilt, you know, Shangyuan City will definitely not be so harmonious between the true god mid-stage powerhouses, under normal circumstances, there should be someone who falls into the well.

On the fifth day of the war, thousands of miles away from the Lufang fortress of Shangyuan City and Taijing City, a figure appeared, and quickly swept towards the Lufang fortress, at this time it was still full of gunsmoke, dead bodies were everywhere, Shangyuan City's resistance was extremely fierce, so that Taijing City was blocked here for five days, and it was not able to break through the Lufang fortress, and the two sides were still facing each other at this time.

In such a tense situation, the precautions of the two sides can be said to be leaky, but no one noticed that the white shadow approached quickly, and then rushed directly into the Lufang fortress, and did not even react to the fortress's formation prohibitions.
