Fantasy: The system takes me to refine the magic formula

Long Tian cleaned up the three devil emperors casually, and his gestures were so easy and insignificant that Feng Ling and the dying Hai Dongtian almost frightened to death!
I am fighting against the opponent, and I know the opponent's ability and strength very well, but the young man in front of me is obviously just a fairy, and he killed three emperor-level masters casually. This is an emperor-level master, not an ant-like existence. Who and how did it happen!

"Hai Dongtian! Are you okay, old man!" Immortal Emperor Tianming helped Hai Dongtian up. Hai Dongtian was also dying at this moment. Long Tian had already seen that the other party must be a living emperor-level master as a sacrifice. , so Haidongtian has only one breath left now!
A ninth-grade elixir was stuffed into Hai Dongtian's mouth, and he looked around. In the distance, Tianman and Luo Bi were still fighting. Both of them were high-level emperors, and no one could do anything to win the other, so there was no major problem for the time being. !
Hai Dongtian originally thought that he was bound to die, even if Long Tian and others came to save Hai Dongtian, but the blows from the three devil emperors were too strong for him, he knew that even if he did not die this time, he would fall into a lower realm, and he did not Thinking of the other party's elixir following him, the wounds all over his body were healing rapidly. In just a few breaths, Hai Dongtian, the emperor of the underworld, recovered seven or eighty-eight!
"Oh my god! This elixir is too powerful! I don't know this young man! What kind of elixir is this?"

"This is the ninth-grade elixir that I made casually. It is for healing. How is your recovery?"

"It has recovered [-]% of its combat power, and it is still recovering now!"

"Hehe, Young Master Long also gave me this elixir just now, and now I am in my prime! Young Master Long is indeed very human! He is so powerful that even emperor-level masters can kill at will."

"What a miracle! Are we going to rescue Master Tianman now?"

"I'll just go by myself! Otherwise, if so many of you go, I'm afraid it won't be easy to keep the high-level devil emperor behind!"

"Then us?"

"Hehe, I have some people who need experience. I brought them here. Come out, Luo Xi and Zhang Mian!" Long Tian waved his hand casually, and then all 19 immortal emperors appeared in front of everyone!

"They! They are all immortal emperors! This..." Hai Dongtian and Fengling looked at each other, with a slight panic in their eyes!
"Long Tian! Is there going to be a war?" Luo Xi asked!
"Look at the distance, you 19 people! The demon army includes many masters of the demon king, demon emperor and other levels! And you are all just promoted to immortal emperors, you need to experience! Go and kill them all!! If there is something to do, I will supervise you after finishing the work!"

"It's Master!"

"Immortal Emperor Tianming, Yanhuo! Look at them, don't let them have trouble! Hai Dongtian, Feng Ling also go to see the excitement! Don't shoot, these people have just broken through and been promoted to Immortal Emperor, they need experience!"

"Yes!"

After Long Tian explained, he turned around and flew towards the place where Master Tianman was fighting in the distance, and then let the system quietly hide his aura!
When Long Tianfei arrived at the battle between Tianman and Luo Bi, both of them were injured, but they still refused to accept each other and continued to be tough!

"Hehe, Luo Bi! Although your demonic energy storage is sufficient, but your demonic attributes are restrained by my Buddhist realm! Suffer death! Ten thousand Buddhas court!" This is Tianmanzai's strongest move, but now he is using it After coming out, he can no longer play the state of his peak period!

"Hehe, when our other devil emperors finish cleaning up the demon emperor and the underworld emperor, do you think you can still escape?"

"You!" Tianman was a monk after all, he couldn't win the other party's argument!
"Master Tianman, don't be afraid, his partners have already become the souls of the sword haha!" Long Tian's voice came from the ears of the two, which shocked them both!
Looking at the boy in front of him, whether it was Tianman or Luo Bi, they were all full of incredulous expressions, how did this boy manage to appear in front of the two of them so quietly?

"Big words! You, a little fairy, are talking loudly with our emperor-level masters! Hehe! I will give you a ride!" Luo Bi casually hit Longtian with a move called Ten Thousand Demon Possession!
Long Tian shook his head: "I originally wanted to let you live for a few more seconds, but you don't cherish it yourself! Then die! Jiuwei Tianhuo! Let me go!" With Long Tian's voice, the terrifying and powerful flame Instantly invaded Luo Bi's body!

For a moment, Luo Bi gave up the attack on Tianman, and felt the powerful and terrifying flames. Luo Bi immediately circulated a large amount of magic energy to resist the power of Jiuwei Tianhuo!

Then just a few breaths, Luo Bi yelled: "No!!!!!!!!! Lord Moraya! Help me!!!!!!!"

Luo Bi is dead!At the same time, Long Tian quickly collected Luo Bi's unconscious souls that hadn't dissipated yet!
"Thank you for this fairy friend!" Master Tianman bowed to Longtian!
"Master Tianman, you are welcome! There is still a war over there, I need to go quickly to collect some souls! You should go too!"

"Okay!" The two flew to the battlefield. Longtian directly manipulated the magic art to absorb the souls above the level of the devil crazily, and the 19 immortal emperors also used this place as a battlefield for experience. All kinds of wonderful and beautiful The big moves of the game emerge in endlessly!
