Of course, Zhou Qing had only encountered such a good thing as sacrificing demonic qi once.

"Husband, a new mission is coming!"

Ye Qingxue's voice sounded.

Zhou Qing nodded to bring up the system interface, and clicked on the task icon again.

Quest, Kill Demons. Task requirements, kill demons, the number of tasks, 10,000 demon commanders, 200 demon kings, 1 demon emperor, task time, unlimited, after completing the task, the host can take the initiative to ask for settlement, the reward is unknown, when settlement, the system will rate the host, the higher the rating, the greater the reward.

Zhou Qing is not a rookie who has just obtained the system, and he instantly saw the clues of this task, simply put, according to the requirements of the system to kill the evil demons, it is estimated that the reward will not be too large, but if you kill as many evil demons as possible, then, the reward will be greater.

Moreover, the system does not give a reward item, which means that the system will most likely tailor a reward item for him.

"Got it!"

Zhou Qing, who figured out the key, directly took over the task, and then ordered the system to open the world with extraterrestrial demons.

Just before stepping into the passage, Zhou Qing paused and asked, "Xiaoxue, if I go over this time, the Heavenly Dao over there won't attack me, right?"

Ye Qingxue said: "Don't worry, the world you went to is being attacked by the Outer Demons, and you have killed the Outer Demons, just by virtue of this, he will also agree with you, after all, the enemy of the enemy is a friend, and the higher the level of the system, the stronger the ability, if the Heavenly Dao of that world wants to wipe you out, the system will not sit idly by!"

"That's good!"

Zhou Qing nodded and stepped into the passage of the two realms.

Soon, he entered a completely new world, and the moment he came to this world, he clearly felt a vast divine thought notice him, but just swept over him, and swept it directly.

Suddenly, Zhou Qing's heart was relieved, knowing that he, an outsider, would not be wiped out by the Heavenly Dao of this world.

Immediately, his mind unfolded, and he found that the world was engaged in a large-scale battle.

The two sides of the war, one side is the native creatures of this world, and the other side is the demons from the outside world.

Judging from the current battle situation, the local creatures are in a weak position, and many forces have retreated with their disciples, but more creatures have been killed and devoured by the demons outside the world.

The number of demon soldiers who came here reached more than 500 million, and there were many demon generals and demon commanders in the army, but this world was too big, and the population was extremely huge, and the demon army was scattered, and it was difficult to destroy all the ontological creatures in a while and a half.

At the same time, there are also thousands of demon kings who are leading a group of elite demon commanders around to attack the representative forces of the ontological creatures.

As for the Demon Emperor, there is no one in this world, but there are seven in the outside of the sky, and there are also masters of the main god level in this world, but there are only six, so they don't dare to make a move, because once they make a move, the Demon Emperor outside the sky is bound to make a move.

"Yu'er, take Yun'er away! Leave a broken queen for the teacher! ”

At this moment, a group of creatures dressed as immortal cultivators flew in Zhou Qing's direction, and behind them were three demon soldiers chasing and killing them.

Among this group of people, the strength of an old man in Tsing Yi is the strongest, barely reaching the level of Immortal Nine, and the others, the strongest is the black-clothed young man who is called Yu'er by the old man, who has the cultivation of Immortal Eight.

Therefore, even if they have an advantage in numbers, they are no match for the three demon soldiers.

"Master, it's better to stay in vain!"

Cheng Yu shook his head violently.

The old man said quite stubbornly: "No, these demons are too strong, you are not their opponent at all, staying will only sacrifice in vain, Cheng Yu is the master and ordered you, immediately take everyone to go first, remember, no matter what, you must leave a legacy for my Nine Star Sect!"

"But Master!"

Cheng Yu wanted to continue talking, but was interrupted by the other party's glare, and yelled at him: "Cheng Yu, if you dare to disobey the order of the teacher again, the teacher will expel you from the Nine Star Sect!"

"Yes, Master! Take care! ”

Cheng Yu knelt down and kowtowed three times to the old man, and then fled quickly with the others.

Seeing this, a hint of relief appeared at the corner of the old man's mouth, and then, he turned around abruptly, faced the three demon soldiers, and sacrificed a chessboard-like immortal weapon, and then, the black and white children in it flew out, forming a large array in the void.

In this regard, the three demon soldiers were not afraid, and burst into the big array, and suddenly, there was a violent turmoil in the big array.

Seeing this, the old man hurriedly played a series of formation tricks, but the three demon soldiers were too strong, and these demon soldiers were all made in batches, unlike human beings with complex minds, it can be said that the phantom array is almost useless to them, which makes the formation greatly discounted.

Therefore, in just half an hour, the large array was already about to be unable to hold on, and it was about to collapse at any time.

Seeing this, the old man's face had a will to die, and he planned to cast some kind of secret method, and when the demon soldiers broke the formation, he would give them a fatal blow, and it was expected that after this blow, he himself would not be much better.

So, Zhou Qing stopped watching the play, appeared from the void, raised his hand and pointed out.

The pale golden finger light submerged into the formation, and then exploded, directly smashing the three demon soldiers to pieces.
