Fantasy: The system takes me to refine the magic formula

"Who is the closest to the underworld?"

"It's the demon world and the Buddha world, and now the Buddha Emperor and the Demon Emperor are also on their way!"

"The demon world must have come prepared, they must be waiting to wipe out the three emperor-level masters of the three worlds!"

"Master! Shall we go?" Yanhuo asked!
"How long will it take us to go from here to the underworld?"

"Master! I will fly with all my strength, for 3 days!"

"The speed is not good! Let me think about it!"

Long Tianru Ding closed his eyes, but he was actually communicating with the system!

"System, is there any way?"

"Host! Either you can create a flying fairy with high speed, or you can only use the law of space, but this is only controlled by gods, there is no other way!"

"Hey, I'm really drunk!" Long Tian opened his eyes again: "Yanhuo, let's go! You 19 low-level immortal emperors have entered my space!"

Long Tian didn't ask for their opinions, and directly took people into his own system planting space, and then pulled Yanhuo and Tianming to fly away!
"You three immortals are in charge of the fairy world for the time being!"

"Yes! Master Long!" The three of Ruoyun replied!
"Yanhuo flies at the highest speed!" The three of them flew into space, and Long Tian gave orders to Yanhuo!

"It's the young master!" After receiving Longtian's order, Yanhuo took Longtian and Immortal Emperor Tianming and set off at high speed. This was the first time that Yanhuo used all his strength to fly. The gap with Immortal Emperor Yanhuo, even the speed difference is so much, if he really stood up, Immortal Emperor Tianming might not be able to pass three moves in Yanhuo's hands!

Of course, if it was a real battle, Tianming would fight Longtian, if Longtian used Jiuwei Tianhuo, Immortal Emperor Tianming would still be no match! !

"Can Yanhuo go any faster?"

"Master! I'm already at the maximum speed, and now I'm flying with the power of immortals!"

"This is a ninth-grade elixir, swallow it, and continue! Immortal Emperor Tianming, what's going on in the underworld?"

"Master Long! People from the demon world and the Buddhist world are flying there. At this moment, Emperor Hai Dongtian opened the shield of the underworld to resist the invasion of the demon world! It's just that the devil emperors in the demon world know the blood demon magic. This blood demon magic is It can assimilate all the energy of the same level and extremely low, I am afraid that the Underworld Emperor can't last long, we can only wait for the Demon Emperor and Buddha Emperor to arrive quickly!"

"What about the people in the spirit world?"

"Just like us, we are rushing to the underworld. In fact, we all hope that the starting point of this war is in the underworld, and the final end is also in the underworld. It is better not to hit the other four worlds, otherwise all interfaces will be invaded, and the lives will be ruined! "

"Yeah!" Long Tian thought for a while, his 19 immortal emperors were considered second-hand, and he also had the super big move Jiuwei Tianhuo. He felt that they should not have the possibility of losing this battle, it's just who I can't be sure what the final result will be, so I can only quietly go to the underworld and watch it again! !
At this moment, Underworld Emperor Hai Dongtian is bringing four Underworld Venerables with him, and several underworld-level masters are supporting the shield of the entire Underworld with all their strength. Once the shield is breached, they will face three demons from the Demon Realm. The emperor, dozens of demon kings and hundreds of millions of monsters attacked his underworld!

Hai Dongtian was also very speechless, he had been cultivating in a low-key way, why did the demon world attack him first in the underworld this time, although he was an intermediate emperor of the underworld, but the other party actually had three demon emperors, two of them were high-level demon emperors, and the other One is a newcomer!This made Hai Dongtian have always been very curious about the birth of monsters in the demon world, and at the same time secretly anxious. Now he has no other choice but to wait for the demon emperor and Buddha emperor of the demon world to arrive quickly, then he can recover temporarily !
The super shield of the underworld consumes the power of these people very much. Hai Dongtian is not sure how long he can last, but he can only grit his teeth and resist. Once the shield is broken, he can escape with four ghosts, but he is not in the underworld. The disciples and grandchildren, as well as those bones and bone dragons, and all other creatures will be swallowed up by the demon world!

After struggling for two days, the three demon emperors led more than a dozen demon venerables to absorb the shield of the underworld, when suddenly a powerful five-element magic directly hit the group of demon venerables!
Kill four demons directly with one move!

"Jie Jie Jie Jie! Demon Emperor Wind Chimes! Now that you are here, please appear!"

"Hehe, the third devil emperor appeared in the devil world!" Feng Ling's figure slowly appeared in front of the devil emperor!
When Hai Dongtian saw the appearance of Fengling, he immediately removed the shield of the underworld, and flew to Fengling's side. Not afraid!
After all, the wind chime appeared, thinking that the holy Buddha Tianman had also arrived!

"Old man Tianman! Don't be invisible, people who practice Buddhism also do things like stealing chickens and dogs?" A senior devil emperor sarcastically said!
"Amitabha! Devil Emperor Luo Bi, long time no see, old friend still!"

"Hehe, the three of you are really bound together! Fortunately, we came prepared!"

"Your Majesty Luo! You must know that the seal above the Six Realms is getting closer and closer to us, and you Demon Realm are launching a war at this moment! Could it be that you want to break the balance of the Six Realms?"
