What's more, the frequency of Qin Zheng and Yi Yun'er's attacks completely exceeded the speed at which the demon lord evolved into a ghost hell. For every ten people they killed, the Demon Lord only evolved five people, and as long as they continued, the situation would fall to Qin Zheng's side.

"Whoa, damn human!"

The demon lord was finally not calm, he hid in the ghost hell crowd that he had evolved, although he had not been harmed, he could feel the power of the magic weapon in the void.

At this moment, Qin Zheng captured the source of the voice, a young man in a white robe, handsome and handsome!

It's him!

Demon Lord!

Give me death!

Qin Zheng was overjoyed and roared, and in an instant, a majestic True Yuan came out, blasting straight towards the white-robed young man.

In an instant, the laws of heaven and earth instantly froze, and the white-robed young man's face changed, and he came into contact with the power sent out by Qin Zheng, but after a moment, he screamed: "Ah, my power!"

In just a few breaths, the Demon Lord sensed that his Origin Power had been destroyed by Qin Zheng!

He roared in distress: "Human beings, damn it, have plundered thirty percent of the hard-won power of my uncle, and I will put you in hell forever!"

As soon as the words fell, the white-robed young man disappeared abruptly, turning into a point of light and disintegrating, and Qin Zheng's locked breath fluctuated and disappeared in an instant.

Witnessing this qiē, Qin Zheng knew that the demon lord had separated the body into another branch.

On the other side, Yi Yun'er continued to suppress other derived ghosts and ghosts, I have to say that this magical power is really disgusting, the enemies are endless, and it will never be finished, and the strange thing is that the creatures derived from this derivation all have powerful power, it's really disgusting!

After a while, Qin Zheng and Yi Yun'er fought with the demon lord for more than a thousand rounds. As they had predicted earlier, the two of them worked together to deal with the Demon Lord. Sure enough, there is a fight!

Seeing this, Yi Yun'er secretly said that she was lucky, and fortunately met Qin Zheng here. Otherwise, this time I will fight this demon lord alone, and I will definitely have no chance of winning.

The demon lord is hidden in the ghostly hell, constantly sending out various spells, and while attacking, he screams.

"Humans, cunning humans, ahhh Kill me!"

After a while, it became the voice of temptation again.

"Human, I see that you have some ability, why don't you follow me, you see that there are many treasures and magical powers, as long as you like something, I will give it to you. ”

Qin Zheng sneered: "You monster, really think that you are the emperor and control a world, and you don't pee to take care of yourself!"

The demon lord was furious: "I recruited you because I could afford you. Don't think I'm scared of you kid!"

A violent and gloomy momentum emanated from the demon lord's body, Qin Zheng was suddenly shocked, and hurriedly shouted: "Yi Yun'er, withdraw!"

He didn't explain anything. The direction of direct contact recedes. Seeing this, Yi Yun'er also hurriedly followed the flying sword, and the two turned into swords and roared away from the mass grave.

The speed of the flying sword is extremely fast. In the blink of an eye, Qin Zheng and Yi Yun'er flew out of the range of the mass grave.

As for the mass graves. The demon lord finally brewed a big move, and he was excited to release it, but when he opened his eyes, he found that there was no one in front of him, and the two humans had already slipped away, and he was suddenly angry: "Cowardly humans, damn, hateful!"

The ultimate move has been brewed, but unfortunately there is no goal, the demon lord can only fight out at will, and for a while, he saw that the heaven and the earth were discolored, the true yuan was disordered, and the sun in the sky completely lost its brilliance.

On the other side of the mass grave, Yi Yun'er, whose spiritual sense had been locked on the battlefield, felt a strong ** coming, and couldn't help but be afraid: "It's good that you prompted, otherwise I won't be able to escape!"

Qin Zheng smiled reluctantly, sat cross-legged, and seized the time to recover.

A quarter of an hour later, Qin Zheng reluctantly smiled bitterly: "That demon lord is very strong, but he also has his own weaknesses. His magic power is very powerful and destroys the world, but before it is released, there will be a strange true element fluctuation in his body, and the spell will take a long time. The first time of the year, I almost died under that big move, and then I narrowly escaped a catastrophe, and I have been thinking about it for the past few years, but I have studied some rules, and now I really use it. ”

Hearing this, Yi Yun'er blushed even more, if it weren't for Qin Zheng, she would have died completely today, let alone save her junior sister.

With a slight sigh, she lifted her mind and forced a smile: "Well, you are also very powerful, in a short period of time, you can grow to such an extent, it's amazing." ”

Qin Zheng shook his head, "I'm just lucky." ”

After speaking, both of them fell silent, not knowing what to say, and the atmosphere condensed for a while, as if both of them felt that there was an indescribable love in each other's hearts, but they didn't want to find out.

After a moment of silence, Qin Zheng finally spoke.

"That palace was wide open just now, and I saw a lot of treasures piled up, all of which were treasures looted by the demon lord in the mass grave, maybe the jade dew bottle we were looking for was inside. ”

"Yes, I noticed it too. But now that we know the power of the Demon Lord, we can't crack its ghostly hell, how can this be good?"

She is also concerned about chaos, as long as she thinks of her sister unconscious, she is nervous and has no calm.

Qin Zheng gritted his teeth and snorted: "There is no way, you can only fight hard, whoever can't stand it first will admit defeat!"

After speaking, Qin Zheng rushed into the mass grave again.

Seeing this, Yi Yun'er felt the pressure in her heart, and the next moment her expression was firm, she clenched her magic sword, and followed behind Qin Zheng, killing the demon lord again.

The demon lord had been roaring in the mass grave, and suddenly felt that Qin Zheng and Yi Yun'er were coming back again, and he couldn't help but be overjoyed, and the two sides broke out fighting again.

You attack and defend, you retreat and I advance, both sides are strong, full of energy, the world is discolored, and the mountains and the earth are cracked.

In this way, Qin Zheng and Yi Yun'er continued to attack the demon lord, anyway, they had already found each other's rules, as soon as the demon lord released his ultimate, they quickly sacrificed their flying swords and fled from the battlefield.

The demon lord was confined by the mass grave area and couldn't leave this place, so he suddenly screamed in anger, but he was helpless.

Again and again, again and again, for several rounds, Qin Zheng and Yi Yun'er continued to attack the Demon Lord, and the two sides fought together. Barely on par, no one can help anyone.

In the back, both sides know that this battle is all about their own willpower.

Whoever can't stand it first loses.

Another big battle, Qin Zheng and Yi Yun'er escaped the attack range of the demon lord, the two of them were so tired and out of breath that they hurriedly sat cross-legged, seizing the time to recover their bodies.

The other side. The Demon Lord was angry, and he was like thunder, and for three whole days, he was fighting with those two humans.

If it was a normal battle, it would be fine, but every time it was a critical moment, he made a big move to deal with the enemy, and the two humans fled, leaving him with no way to start.

A wave of anger in his heart was held back like this, making the demon lord feel that his face had been greatly provoked. However, he could not get out of the mass grave area, and naturally he was helpless against the enemy.

As a result, this demon lord simply stirred up the wind and clouds in the void angrily, and the angry scolding spread all over the world.

"Despicable humans. Have the guts to come out and fight me for 300 rounds!"

Qin Zheng and Yi Yun'er naturally ignored him. Although the demon lord is powerful, he doesn't seem to be wise, and his consciousness comes from the absorption of the consciousness of thousands of undead, and the wisdom of some human beings. Not adaptable.

A few hours later, Qin Zhenghui simply rummaged through the Heavenly Mirror. Looking for supplies that can be used to deal with the demon lord.

The elixir is a must, and the Demon Lord's ghostly hell is endless, so they need to keep their bodies full of true yuan at all times. Eh, this is ......

Suddenly, Qin Zheng looked stunned, as if he had discovered something, and showed a contemplative expression.

At the same time, Yi Yun'er also recovered her body at this time, and saw that Qin Zheng was in a state of contemplation, did not disturb him, and was idle, and suddenly a thought suddenly appeared in her mind.

By the way, the demon lord is so powerful, but why can't he leave the area of mass graves?

Yi Yun'er was suddenly extremely curious in her heart, and wanted to ask Qin Zheng, but seeing him in a deep thought, she simply rose into the air and probed the area around the mass grave.

Both of them were doing their own things, and an hour later, Qin Zheng was the first to wake up, and at this moment, he suddenly had an idea in his mind.

Yes, he had an idea for dealing with the demon lord.

Looking around, he couldn't help but jump when he saw no trace of Yi Yun'er, could it be that there was an accident? Just as he was about to look for Yi Yun'er, a glow flew in the distance, landed on the ground, and a graceful figure rushed towards him excitedly.

Yi Yun'er looked excited, jumped on him excitedly, and said happily: "I know, I know, I finally know!"

Qin Zheng suddenly hugged Yi Yun'er in embarrassment, not letting it go, not hugging it, but seeing Yi Yun'er's happy expression, he didn't want to talk about infection, and said with a smile at the moment: "Yi Yun'er, why are you so happy?"

Yi Yun'er said excitedly: "I flew around this area just now, and I finally found out that the reason why the demon lord couldn't leave the area of the mass grave was because a magic array was set up here. Maybe it was the means left by those ancient monks back then, afraid that the corpses of their companions would change after their deaths, so they set up a blue sky and white sun array here!"

"The Blue Sky and White Sun Array is the Ancient Demon Sealing Array, the principle of this law is to use the power of the laws of heaven and earth, light suppresses darkness, and heaven and earth suppress evil demons, so no matter what, no matter how powerful the demon lord is, he can't get out of the area of the mass grave, and he can only be sealed here forever!"

"I thought of a way, maybe my sister can be saved!"

Speaking of this, Yi Yun'er realized that she was too pleasantly surprised, the whole person was hugged by Qin Zheng, and under the touch of the skin of both parties, they both felt the heat of each other's bodies, she couldn't help blushing and wanted to struggle out.

The ghost made the gods, but Qin Zheng hugged him tightly, so that his entire cheek was attached to Yi Yun'er's body, smelling a touch of fragrance from the end of his nose, and the whole person was extremely hot.

Yi Yun'er was also hot, it was the first time she had such intimate contact with a man, after being hugged hard by Qin Zheng, the whole person suddenly felt weak, her body was numb, and she almost fell, but fortunately Qin Zheng hugged her tightly, so it was fine.

In this way, there was silence on the field, and an ambiguous atmosphere filled the hearts of the two people. After a long time, Yi Yun'er took a deep breath, and finally broke out of Qin Zheng's embrace, and then her ears were hot, and she lowered her head gently.
