Fantasy: The system takes me to refine the magic formula

Ji Yurou, Feifeng and Xue Tiankuang watched Dan Chenzi and Ling Yuan being injured again in the distance, but they still defended each other to protect the three of them. The three of them were very moved. They also knew that once one of these two If you can't stand it anymore, the three of them will be killed at any time!

"Oh my god! What is that!" Xue Tiankuang suddenly pointed in the direction far behind him, and a black line flew towards him!

"..." Feifeng and Ji Yurou were also taken aback. After a while, they saw clearly that it was actually a black dragon!

"This... Could it be a dark dragon!!! Oh my god! There is someone on the dragon's head!"

"It's my apprentice Hongying!~!!! We are saved!" Ji Yurou suddenly wanted to cry!In this battle, I don't know how many disciples I died or were demonized, and even I almost confessed here. At this last moment, my apprentice actually carried a dragon to save me!

"Ji Yurou! Do you have dragons in Tianwu Academy?" Xue Tiankuang was shocked when he heard Ji Yurou's words!

"This...not at all! I don't know where Hongying's dragon came from either!"

"Master!!!!!!!!!!" Hongying from a distance started to shout, and then said to Xiao Hei: "Those demon generals are enemies! I'll leave it to you, Xiao Hei! Kill them!! !!!”

Xiao Hei didn't say a word, just rushed away!

Hongying landed on Xiao Hei and stood beside her master: "Master! Are you alright! Huh, huh! I'm so worried! I saw explosions on your side from a long distance, and there was even a huge energy wave Vibrating to our side, I thought something happened to you all!"

"Silly girl! Master is fine, it's just that he suffered backlash and needs to rest for a while!"

"Girl! Girl! Where did your black dragon come from?" Xue Tiankuang and Feifeng asked together!
"Back to the second master, this belongs to my young master, it has been hatched for a long time!"

"It belongs to Longtian! But doesn't he have a ninth-level monster as a pet? How can he sign a second one!"

"I don't know, maybe the young master's soul is also magical! Anyway, the young master is a magical genius!"

Feifeng was also very excited when she heard Hongying's words, she always felt that Longtian had a way to save Phoenix in her sect!

Dan Chenzi and his opponent, the demon general, fought in the dark, but they were still not the opponent's opponent. There was no way. Without the replenishment of magic energy, but because I have been taking pills, now my spiritual power is exhausted, and I have no chance of winning. It's a pity that I don't have a chance to see my precious apprentice!

When Dan Chenzi was about to give up, a black figure directly tore apart the demon general opposite him, and then ran to Ling Yuan in the distance!
Ling Yuan was also at the moment of life and death when he suddenly found that the demon opposite him was swallowed by a giant black dragon!

Then Ling Yuan and Dan Chenzi looked at each other, and they both made black question mark faces!
"Dan Chenzi! This dragon?"

"I don't know either! I was about to give up just now, but this dragon appeared and directly killed my opponent!"

"Me too! What about Feifeng and the others!!"

"Go! Go and see!"

When the two found Feifeng, Hongying stepped forward immediately: "Master! Long Tian is back! He's fine! Let you rest assured!"

"Good! Hongying! There was a dragon just now..."

"It's the young master's magic pet! It's called Xiao Hei! With him here, we don't have to worry about anything! Shishu, you and head Ling Yuan should heal quickly! Don't delay the best time for healing! If you have any questions, you can ask the young master after seeing the young master." In time!"

Dan Chenzi and Ling Yuan were relieved when they heard Hongying's words!
"Long Tian is a tough guy, he can handle two monsters, and they are all so powerful!"

Hongying looked at Ling Yuan and thought of the Silver Moon Demon Wolf. If this old guy knew that his young master got three of them, wouldn't he be scared to death!

Not long after, the two elders of Tianxuan, Bei Nian, Jian 23 and others also returned to their side, and at the same time followed a young black-robed boy!

"Are you guys all right?" Feifeng asked!
"It's okay! This...er, this boy arrived in time and swallowed a few demon generals alive, so we were freed!"

"Xiao Hei! Well done!"

"Hongying! I'm going to find the young master! Now the young master is still fighting hard, I have to help!"

"Xiao Hei, take me with you!"

The boy in black robe instantly turned into a giant dragon, and the red tassel flew onto the head of the black dragon, and then flew into the distance!

"It's really shocking! On our Tianwu Continent, there are dragons!" Jian 23 said with emotion!
"Hehe! This is my apprentice's magic pet! Senior brother, I think this dragon is stronger than a ninth-level monster! Could it be the legendary holy-level monster?"

Dan Chenzi's words cheered everyone up. If it is a holy monster, then there is hope for killing the monster!
"Dan Chenzi, I'm going to help other people! After resting, organize the surviving monks to gather together, and don't disperse! Be careful to be demonized by other demon soldiers!" Bei Nian and Jian 23 left the crowd, leaving After getting off, the two elders of Tianxuan helped the several heads recover quickly!

At this moment, Long Tian was almost in the state of blocking and killing demons on the battlefield. In a few breaths, he killed all the monsters and bone pterosaurs around him, without leaving a trace of life, as if he was venting something!
People around were a little worried when they saw the faint black devilish energy on Longtian's body!
Long Tian ignited the Three Flavors True Fire, which instantly melted away the devilish energy around him!
And the battle between Golden Wing, Silver Moon Demon Wolf and Colorful Sky Heron also came to an end after killing the last demon soldier!

"Long Tian!!!!"

"Master!"

Luo Xi and Hong Ying saw Long Tian in the air, and rushed towards Long Tian's position one after another!
"Are you OK!"

"I'm fine! Nothing at all! How about you Luoxi?"

"I'm fine. I've been helping injured practitioners on my father's side. Occasionally I can participate in the battle, but it's all about saving people!!"

"Master!"

"What a big black dragon!!!" Luo Xi shouted when he saw Xiao Hei!
"Luo Xi! This is the young master's partner named Xiao Hei!"

"My God! Long Tian! You actually have a giant dragon! What else do you have, I don't know!"
