Fantasy: The system takes me to refine the magic formula

Dan Chenzi looked at the harmonious relationship between Longtian and Zhang Mian, and suddenly thought of the relationship between himself and Longtian. Never mind, I have been relying on myself from the age of 3 to the age of 16. Now that I have reached the stage of crossing the catastrophe, as a master, I really haven't fulfilled enough responsibilities, and I am ashamed!
The three of them flew to Beinian Tianfeng!

Bei Nian, Ji Yurou and others have been waiting for a long time!
"Oh my God!!! Long Tian!! Three days ago you were still in the middle of the tribulation period! I can still see your realm clearly! Now there is no way to spy! Could it be you..." Bei Nian no longer knows how to describe it!
"Hey, Uncle Master! Long Tian just had a small breakthrough!"

"What a small breakthrough! From the mid-term to the late stage of the tribulation period! Is this a small breakthrough? Do you know how many years I have to practice to achieve such an achievement! You are really... a pervert!"

"Master! At your speed, Hongying can't catch up again! I thought there was hope, but the young master fell behind again! Really!"

"Uncle Master! Uncle Ji! This is my apprentice! Zhang Mian!"

"Hello, masters and uncles!"

"Good! Another genius! Looks young! How old are you?"

"Reporting to Master Uncle, this disciple has just turned 20!"

"A 20-year-old in the middle of the Mahayana period! Hehe, good! There are more and more talented disciples in my Tianwu Academy! Long Tian! Let's go, I will take you to see the venue I found? I don't know if it suits your wishes! "Bei Nian took off happily!

A group of people followed and took off!

All present were cultivation bases of the Mahayana period of the Tribulation Transcendence period, so the speed was very fast. In just half an hour, Long Tian and the others arrived at the junction of Tianwu Academy and Guisen!

"Uncle Master! Here?"

"No Long Tian! I set the place 2 kilometers ahead, which is within the range of Ghost Forest, and it's still far away from our Tianwu Academy. I don't think this distance will affect the aura intensity of our headquarters. Yes, and Guisen has almost no one practicing here for so many years, so the aura is definitely sufficient! Longtian, do you think it can be done?"

"Yes, yes! It's just that this place doesn't seem to be big enough!"

"Long Tian! Follow me to see! This is a place where there is another village!"

Long Tian followed Bei Nian to fly again for 1 minute, and suddenly saw a huge plant. The torso of the whole plant was as big as an airport runway!
Long Tian finally understood the meaning of Bei Nian's words, this place is really suitable!

"Uncle! No problem! We can start anytime! You can let the disciples come over!"

"Okay! I have asked my disciples to prepare in advance! Wait a moment!"

Everyone sat on the giant tree of Ghost Forest, and then waited for the arrival of the disciples of Tianwu Academy's transformation stage and above!

Three hours later, all the disciples arrived and found their suitable place, and Yuan Kai, Ji Yurou, Dan Chenzi and Bei Nian were also ready!

"Hongying! You go too! Zhang Mian, you go too! The master will control the aura of heaven and earth to infuse your body for a while, so don't resist, and don't be nervous. After receiving the aura, work hard to circulate the dantian, and then practice quickly!"

"It's the master!"

The other disciples saw that Long Tian accepted an apprentice at such a young age, and no one could see the cultivation of this apprentice clearly, which proved that his realm was higher than his own, and all apprentices were like this. The realm is even more terrifying!

Everyone got ready, but Long Tian closed his eyes. This time manipulating the aura of heaven and earth was the most intense aura he had ever manipulated. Not to mention filling his body with five monks who were going through the catastrophe period. In many Mahayana, Fusion and Transformation stages, Long Tian is also looking forward to how much aura he can control, and even more so how strong he can be now, after all, this is his first shot after breaking through!
Under Long Tian's control, a huge vortex with a diameter of one thousand meters suddenly appeared in the sky, and then Long Tian used the magic formula to crazily search the spiritual energy for several miles around into the spiritual vortex, because there are not many people at the moment, so Long Tian just controlled the vortex within a thousand-meter diameter range!

Seeing how powerful his master is, Zhang Mian was even more excited, trying to work hard in the direction of his master!
But Dan Chenzi and the others used to watch Long Tian give other people's aura empowerment outside, and they didn't know how it felt to sit under the vortex, but the huge aura vortex above their heads shocked several of them!
With his eyes closed, Long Tian exhausted his greatest mental power and control to frantically search for all the spiritual energy in the vicinity, and even used the spiritual energy on the ground of Guisen. It was used, but this time it was searched and taken away by Long Tian!
And Long Tian hasn't had spiritual empowerment for a long time, because he is not ready yet!
Long Tian didn't know how much aura would be needed for the empowerment of the five masters of the crossing tribulation period, so he could only keep blessing and accumulating aura until the aura in the vortex could no longer be filled, that was the limit!
At this moment in the sky, the aura vortex is spinning faster and faster, and the color of the aura contained in it is becoming more and more intense, from transparent at the beginning to light blue, and now it is dark blue, Long Tian did it again A bold decision!
"Everyone! I want to fill it with some fairy energy! It will definitely help you! Are you ready! Reiki empowerment!"
