The strongest assassin training system

Chapter 424 Black Mist
But our poor demon master has no choice but to conspire against Nie Zheng at this moment. He even stopped searching and bombing Nie Zheng, for fear of triggering some of Nie Zheng's traps, he carefully looked around and began to defend himself.
And Nie Zheng broke through with the speed of a god in such a delicate environment.
"Level 47, Level 48, Level 49." Another 3 minutes passed, and Nie Zheng made another three consecutive breakthroughs. At this moment, the duration of the shadowy shadows has almost reached the end, leaving time for Nie Zheng to break through There are not many left.
"Level 50!" Nie Zheng once again completed a major leap in his life. He reached level 50, which means that he can almost be described as invincible in the southern border.A level that is absolutely strong above the Tianshan Mountains, but I just don’t know if Nie Zheng has the life to enjoy the days after he reaches level 50 because at this moment, the duration of Shadow Heavy is completely over.
The Demon Master regained his eyesight, and Nie Zheng also showed his prototype
"Could it be that he ran away!? Impossible, how could the dozens of masters he just killed me run away, and just now in the dark night formation, I clearly felt a breakthrough force, there must be something Ambush, and since there is an ambush, that person must still be there!" The Demon Daoist became more certain of his guess.Just when he was sure of his guess and was about to take two steps, he suddenly found something blocking his way.

"Ah!? What. Ah!!!" When the demon master felt something blocking him, he looked down subconsciously, but found Nie Zheng sitting cross-legged in meditation sitting in front of him. It really shocked him.The whole person was startled and took dozens of steps back before stopping. Only then did he have the patience to look at Nie Zheng carefully.
"He seems to be breaking through?" After the Demon Master finished speaking, he shook his head. How could it be possible for someone to sit in front of the enemy and break through so boldly?He couldn't believe it, but the person sitting in front of him was so real. If the aura of breakthrough in the shadows just now might have been confused by Nie Zheng, then now Could it be that the real Nie Zheng of the author in front of me was also imitated by him?This... Is this still an assassin?Shouldn't this be something that can only be done by the fantasy formation of a magician?
The master of the demonic way began to be suspicious, and slowly moved towards Nie Zheng
At this moment, Nie Zheng, whose breakthrough has reached the most critical stage, is completely unaware of the dangerous situation outside, and can only see the energy core in his mind constantly surging, constantly charging at every move of Nie Zheng. The meridians emit energy, and his whole body is covered with a layer of gold, and the cyclone keeps spinning as if to absorb all the energy in the world, but the energy in the energy core seems to be inexhaustible Normally, no matter what the cyclone asks for, he will rush towards it violently and will not stop
"Roar!" Nie Zheng roared involuntarily, and everything fell into place. The golden light became even more dazzling at that moment! !

And at this moment, how can the master of the devil not understand that this GRD Nie Zheng really made a breakthrough under his nose, and looking at the golden light flowing above his body, it was a breakthrough to level 51 The sign, this thing, not only doesn't care about completing the breakthrough at all, but also reaches level 51!The realm of your dreams!

"Ah!" The demonic disciple was about to go crazy. Along the way, he faced no one to crush. He stepped into the Western Regions by himself. In just half a year, he unified the Western Regions and killed dozens of 40-level masters. I took it for my own use, but in this short period of time, all my level 40 masters were beheaded by Nie Zheng, and in several confrontations with Nie Zheng, all of them were at a disadvantage. What's more, he also completed the breakthrough to level 51 under his own nose?Just sit next to yourself! ?It was ridiculous for me to think that it was his trap. This was so stupid that the evil master couldn't forgive me!
He roared angrily and waved his staff to kill Nie Zheng who was making a breakthrough. Only this action could calm the anger in his heart!
But just when his staff was about to hit Nie Zheng's head, a change happened. Nie Zheng opened his eyes. The golden light on his body hadn't dissipated. He stood up instantly, holy Stimulated by the golden light, the sorcerer could barely open his eyes.
"Ah!" He closed his eyes in pain.

Looking at this scene, Nie Zheng knew that he had won the bet. He laughed loudly, took out the dagger, and stabbed viciously!
"Pfft!" The dagger pierced into the center of the demon master's palm, and blood flowed out, but the blood on the wound was instantly evaporated by the holy light, and the wound continued to open at a terrifying speed!
"The feeling of a 51-level powerhouse is really great!" Nie Zheng smiled and looked at the big disciple of the Demon Dao. Although it was only a short 10 minutes, Nie Zheng's strength has changed drastically!

"Blade cherry strangling chaos!" Nie Zheng raised his dagger, the afterglow on his body that had just been promoted to level 51 still hadn't completely dissipated, and the dazzling silver-white light shone again, and the terrifying power seemed to be able to destroy everything!
The silver-white energy quickly formed a huge silver-white sword energy in the air, blasting and killing that demon master!

"Bang!" Blood rained all over the sky!
Yes, just for a moment, the demonic disciple who had just fought with Nie Zheng and was able to escape by relying on the black mist, was instantly killed by Nie Zheng. Nie Zheng has always been fighting with a low challenge level. High, and when Nie Zheng's level crushes others, the strength he displays can only be described as destruction level.

"Soul Extinguishing Powder." Nie Zheng watched the last drop of blood rain drop to the ground, and the expression on his face was finally completely relaxed. This battle is really much more difficult than he imagined, but it is the final result. It's good.

"Drip! Kill the master of the devil, and get the god-level skill of the master of the devil - black mist." The voice of the system rang in Nie Zheng's ear.

Nie Zheng's expression instantly entered a state of ecstasy. He had felt the power of the black mist just now. It was simply too strong to be stronger, and he still accepted such skills as an assassin. That's even more so. Like a tiger with wings added.
