The moment the Demon Sword Blood Blue Sky appeared, the Heavenly Demon Emperor felt a huge oppressive force coming towards him, making him a little breathless!

The Demon Knife Blood Qingtian is just a magic weapon equivalent to a four-grade magic weapon, but Nie Feng has a vague hunch that this magic weapon is not simple, and it may be useful for the Heavenly Demon Emperor.

Sure enough, the moment the Heavenly Demon Emperor saw the Demon Sword's blood and blue sky, his face changed greatly, and he subconsciously wanted to escape, and even forgot to kill Nie Feng!

"Demon God Blood Blade, this is the Demon God Blood Blade!"

The Heavenly Demon Emperor muttered and fled quickly, lest he be caught up by the Demon Sword Blood Blue Sky.

Seeing this scene, Feng Mingze, Yu Qi and the others all changed their faces greatly, I don't know what the situation is, just a few demon soldiers actually scared the Heavenly Demon Emperor like this?

Before everyone could react, Nie Feng made a quick move, he controlled Dabai, suddenly increased his speed, and the demon knife in his hand Blood Qingtian stabbed into the body of the Heavenly Demon Emperor!

The Heavenly Demon Emperor screamed miserably, under the attack of the Demon Sword Blood Blue Sky, it couldn't dodge at all, and the oppressive power from the Demon Sword Blood Blue Sky made it feel powerless!

"Damn, how could the Demon God Blood Blade be in your hands!" the Heavenly Demon Emperor screamed.

"Demon God Blood Blade? I don't know, I just have a hunch that this knife can kill you. Nie Feng said indifferently.

"The Demon God's Blood Blade has reappeared in the world, but how could it fall into the hands of a human being?

The Heavenly Demon Emperor struggled violently, but its body was pierced by the Demon Knife Blood Blue Sky, and pitch-black blood continued to flow, and the vitality in its body began to dissipate!

"Phew!"

Nie Feng pulled out the Demon Knife Blood Blue Sky, and slashed out again, splitting the Heavenly Demon Emperor's body in half, and a pitch-black magic crystal appeared in front of his eyes.

Nie Feng's eyes were quick, he snatched the magic crystal, and then drove the big white away! Before leaving, Nie Feng returned to the crowd, took Bai Feng away, and the two of them rode away in the sky.

"Chase! Don't let this kid run!"

Feng Mingze roared angrily, and was the first to chase out, he killed the Heavenly Demon Emperor for the Demon Crystal, and now that the Demon Crystal has fallen into Nie Feng's hands, how can he give up!

Many human martial artists are chasing and killing Nie Feng, the Demon Crystal of the Heavenly Demon Emperor, the temptation is too great, and no one wants to get it.

Mu Yu stayed in the camp of the Ten Thousand Beast Gate, and Nie Feng didn't take her with him when he left, so it was safer for her to stay in the Ten Thousand Beasts Gate, after all, the Ten Thousand Beasts Gate was one of the three super forces of the Lanling Empire.

"Xiao Feng, that demon soldier is so powerful, it can actually kill the Heavenly Demon Emperor!" Da Bai sighed.

"The Heavenly Demon Emperor called it the Demon God Blood Blade, I don't know what the origin of this knife is?" Nie Feng said slowly.

In his previous life, Nie Feng was the Dragon Emperor of the Ages, crisscrossing the Zhenwu Continent, but he had never heard of the Demon God Blood Blade, but he had heard of the name of the Demon God, that was the strongest among the Demon Clan, but it had fallen for many years, and when Nie Feng was still the Ancient Dragon Emperor, the Demon God had already become ancient and no longer existed.

"Maybe this Demon God Blood Blade has something to do with the Demon God of the past, but it's just that I'm still unable to exert its true power. Nie Feng sighed.

The blow that killed the Heavenly Demon Emperor just now, it was the Demon God Blood Blade that was inherently effective in restraining the demon clan, as if it came from the suppression of the soul, not Nie Feng exerting its power.

A large number of people and horses chased after him, but Nie Feng was not flustered at all, he was still very confident in Da Bai's flight speed, with Da Bai here, they would not be besieged by those people, and now the focus was to find a safe place, and then refine the magic crystal.

The Demon Crystal of the Heavenly Demon Emperor is a priceless treasure, if Nie Feng always carries it on his body, then he will become the target of everyone, and everyone will come to him for trouble, but as long as he refines the Demon Crystal, there will be no such troubles, at least those who originally had no grudges will not trouble him.

Feng Mingze chased after him, he summoned many strong people to besiege and kill the Heavenly Demon Emperor, and said that it was high-sounding, what is for justice, in order to kill evil demons, in fact, he is just to obtain the magic crystal, with his current cultivation at the ninefold peak of the giant elephant, once he obtains the magic crystal, he can break through to the Flying Heaven Realm!

However, all this came to naught, Feng Mingze hated Nie Feng deeply, but he couldn't catch up, he was so angry that he trembled all over, and he was about to go crazy.

Da Bai carried Nie Feng and Bai Feng and found a hidden cave, which was almost a thousand miles away from the place where he had just fought, and Da Bai's flight speed was extremely fast, and he had already thrown off Feng Mingze for some distance.

Nie Feng stayed in the cave for the time being, and also arranged a Yuanwen formation outside the cave to prevent the traces from being discovered, and the main function of this formation was to hide the traces.

With Nie Feng's Yuan Pattern attainments, basically no one can find it in the cave, unless it is a five-rank Yuan Pattern Master who comes here, it is possible to discover the Yuan Pattern Formation.

Nie Feng sat down, took out the Demon Crystal of the Heavenly Demon Emperor, and prepared to refine it, while Da Bai stood next to him to help protect the Fa.

In the process of fighting the Heavenly Demon, Nie Feng made a lot of gains, and also obtained many magic crystals, most of which were Heavenly Demon Crystal crystals, and two belonged to the Heavenly Demon King.

Nie Feng assigned these magic crystals to Da Bai and Bai Feng in order to help them improve their strength.

Da Bai and Bai Feng took turns to protect the Dharma, and Nie Feng was immersed in cultivation, unaware of the passage of time.

The Demon Crystal of the Heavenly Demon Emperor contained unimaginable energy, like mountains and seas, and it took Nie Feng a lot of time to completely refine it, and in the process of refining, he could not be disturbed in any way.

The Heavenly Demon Emperor is among the demon clans, standing at the top, and has already condensed his physical body, and its magic crystal can help martial artists improve their cultivation! Nie Feng is currently in the Giant Elephant Realm, and after completely refining the Demon Crystal, it is conservatively estimated that his cultivation can break through to the Giant Elephant Triple Realm! Or even higher! This is the allure of the Heavenly Demon Emperor's Demon Crystal.

In the extraterritorial battlefield, Feng Mingze ordered the disciples of the Pure Yang Academy Palace to search for Nie Feng's traces everywhere, but unfortunately, Nie Feng hid in the Yuanwen Great Array, hiding his whereabouts, and they couldn't find it at all.

Among all the martial artists who entered the extraterritorial battlefield, it was impossible for them to surpass Nie Feng in terms of attainments in the Yuan Pattern!

Time passed, and in the blink of an eye, Nie Feng had been in the cave for two months, and for two whole months, Da Bai and Bai Feng had already finished refining the magic crystals on hand, but Nie Feng was not over yet.

The magic crystal of the Heavenly Demon Emperor is so powerful that Nie Feng still needs more time.

Da Bai and Bai Feng guarded Nie Feng's side, looking forward to Nie Feng's transformation, after two months of refining, the magic crystal became much smaller, only the size of a thumb remained, but it was only a small piece of magic crystal, and the difficulty of refining was also very great.

As time passed, Nie Feng unleashed more and more powerful momentum, and his cultivation made repeated breakthroughs, and he was already a martial artist of the Giant Elephant Triple Realm! Moreover, his momentum was still increasing, and it seemed that he had not yet reached the limit!
