Fantasy: The system takes me to refine the magic formula

"What! Hongying, even you have been arranged by Longtian! This guy is real! Not at all sympathetic!"

"Hey! If I take you two to a dangerous place, I will call you Lianxiang Xiyu? You can figure it out, okay?"

"Hmph! I don't care about you!"

Seeing that Luo Xi was gone, Hong Ying said to Long Tian, ​​"Master! Let me meet Xiao Hei!"

The two directly entered the system space, but what they didn't know was that the two had just disappeared into the room on the front foot, and Luo Xi turned back again on the back foot!
"That's not right! This room obviously has the aura of the two of them, why are these two people missing??"

At this moment, Hongying was looking at Xiao Hei in the system space and shouted: "Wow!! This is the dark dragon hatched from that egg! It's so huge! And it's so dark that it glows! Master really didn't lie to me!"

The dark dragon that turned into a prototype opened its eyes and looked at Hongying: "You are that little girl!"

"What little girl! Call me sister Hongying! Call me quickly!"

"Ah..." Xiao Hei was a little speechless when he saw Hongying like this, but he also had an impression of this girl in front of him. Every time this girl was practicing, she would sit beside her and sometimes talk to her, inexplicably. Yes, Xiao Hei also has a little bit of intimacy towards Hong Ying!

"elder sister!"

"So good! So good!! Oh, you are so handsome and mighty! Young master! Young master! Xiao Hei just called me sister! This dragon is so handsome!! I have never seen a dragon before! This is a dragon! !"

Long Tian looked at the excitedly dancing and chirping Hong Ying, and suddenly had a headache. She was already sixteen or seventeen, and she was still an innocent little girl!

"Ahem! Master, I am your magic pet!" The Seven-Colored Heavenly Heron turned into a bird and flew to Hongying's side, and said!
"Yes! You are mine, but he, he is so handsome! The black dragon! Xiao Qi! Have you ever seen a black dragon?"

"Hongying! Can't you change the word!" Long Tian broke out in sweat, and then he didn't care what Hongying did. After entering the Mahayana period, he hadn't been to the system challenge space yet, and he didn't know what he was doing now. Can the ability be able to single out the masters of the tribulation period!

Before the challenge, Long Tian threw the sword technique that Xue Tiankuang gave him to several avatars!Let a few primordial spirits practice first!

Three days passed by in a flash. Long Tian, ​​Hong Ying and the others got up early this day, adjusted their state, and set off with the large army!
The war has begun!

Among the nine sects, headed by the nine sects, except for the Yaoxian Valley, the Artifact Sect, the Yushou Villa and the Tianxuan Sect, all the sects have entered the tribulation stage, followed by Dan Chenzi, Ji Yurou, and Long Chen. Tian gave Hongying the Golden Wing and the Seven-Colored Sky Heron as companions. Hongying took two monsters of the upper rank of the ninth level, and they were also mixed in the troops of the Transcending Tribulation Stage, followed by the Mahayana Stage, the Fusion Stage, etc. The masters of the Nascent Soul stage and the monks of the Transformation God stage supported by various factions are at the end, gradually forming a comprehension brigade of several 10 people!

But at this moment, Long Tian is sitting on Xiao Hei's body, flying rapidly in a higher place!

This is the first time for Longtian to control a dragon, so don't be too excited, Xiaohei's body is 70 meters long, and there are two black and hard dragon horns on the huge dragon head, and Longtian is sitting in the middle of the two dragon horns!
Xiao Hei's speed is three times that of Gold Wing!Let Long Tian feel how fast the angels in the fairy world are! A few days ago, it took a whole day to sit on the golden wings from the magic gate, but now sitting on Xiao Hei's head, it only takes a few hours!
"Xiao Hei, while descending, be careful of the demonic energy around you!"

"Young master, don't worry, the magic energy is almost the same as the dark element to me! And you have infused me with a huge amount of magic energy essence, so I can grow up so quickly!"

"haha okay!"

In a few seconds, Xiao Hei fell to the ground from a height of tens of thousands of meters in an instant, and then entered Longtian's system space. With the help of the system, Longtian's body entered the stealth mode!
It is still one day before Bei Nian and others' large troops hit the city on the border of the Demon Gate. Long Tian has enough time to find the gate of the Demon Realm, and has absorbed a large amount of magic energy again. Xiao Hei, Long Tian needs to quickly absorb these demonic energy in order to improve his own cultivation. Since entering the Mahayana stage, Long Tian's spiritual power and control have indeed improved a lot, even when practicing the essence , the progress of mental power has become slow, Long Tian knows that it is because his spiritual power was too strong in the past, and now he wants to go further in the Mahayana period. Repeated training is one aspect, and the realm is the most important thing to keep!
Entering the Heavenly Demon Altar again, the intensity of the demon energy here seems to be stronger than last time. Long Tian directly entered the center of the hall like a hell maze. It became eight! !

Long knew how important the pre-war information of this kind of battle was, and after decisively flying out, he hurriedly sent a message to his master uncle!
"Master! There were originally seven masters in the Tribulation Stage in the Demon Sect, but now there are eight! I guess someone will stay in the base camp during the war! Master, don't be careful!"

"Got it, Long Tian! Don't send me any messages! Last time, the aura of the message leaked out! This time, although I don't know what method you used to reach the Heavenly Demon Altar so quickly, and even sneaked into the hall, But you must be careful!"

"It's the master!"
