Fantasy: The system takes me to refine the magic formula

"Hmm!" Long Tian thought for a while, and felt that Hongying's words were also reasonable. Too violent and messy aura can completely stimulate the cultivation state and physique of a cultivator, but when breaking through, although the aura is enough But it is not very docile, and it will cause the cultivator to be unable to break through naturally. If he controls the vortex of the world and triggers the aura to infuse the body, it may be the best choice for the second daughter to break through, and you can also try to let the second daughter fully operate herself The method of cultivation makes it possible to break through realm and martial skill at the same time!
When Hongying broke through before, she encountered a lack of spiritual energy. If Longtian hadn't passed by and saved Hongying, Hongying would have been reincarnated by now. But this time, if Longtian was allowed to control the vortex and fill the two girls with spiritual energy body, then it is really possible for Hongying's Lianxinjue to reach the fourth level, and Luo Xi's martial arts Longtian has never been clear about, and has never asked about it, but any martial arts also needs the backing of spiritual energy, except for the dragon. Tian's magic formula, so Long Tian thought about it, and agreed to the needs of the second daughter!
"I promise you two, but since I want to break through, I will do my best to control the aura of heaven and earth to infuse you two with aura. When the two of you break through, you can also try to break through martial arts! Hongying! This time, the young master is here , you don’t need to worry about the lack of aura!”

"It's the young master! Thank you, young master!"

"Great! Long Tian! Hee hee! When do we start?"

"I can do it anytime! Just look at the status of the two of you!"

"I'm ready!"

"Me too! I've been preparing for a long time!"

"Then let's start!" Long Tian chose a place at random, and now on the island in the middle of the endless sea of ​​magic, the surrounding aura is enough for the two girls to break through. The period is not the period of crossing the catastrophe, nor is it the period of the fire phoenix fairy beast, so the surrounding aura is enough!
The second daughter sat on the ground, getting ready, looked at Long Tian firmly and nodded!
Long Tian smiled and directly manipulated the vortex to absorb the surrounding aura!

Now Longtian's mental power is extremely powerful, enough to create a vortex that exceeds 3000 meters. For the second daughter, the spiritual energy absorbed by the vortex with a diameter of [-] meters is enough. If there is more, the second daughter will explode and die!
Long Tian quickly manipulated the surrounding aura into the vortex, and while manipulating it, Long Tian inexplicably discovered that while the range he could control became larger, even the aura in the ocean was also controlled by Long Tian, ​​and Long Tian Also quietly dissipated a sea tornado that was relatively close to the Longtian vortex with control!
This move made Longtian a little nervous. He felt that the magic formula he had practiced was not as simple as he thought. It seemed that there was still a long way to go for the research of the magic formula. After all, the sea dragon scroll was caused by the power of heaven and earth. Such a phenomenon, but Long Tian actually tried to dissipate it directly with the power of control!This is simply too scary!

The aura vortex on the second daughter's head became bigger and bigger. Both of them were very nervous and looking forward to it, but they didn't have any worries. They only trust Long Tian now!trust!Trust again!

"Are you ready? Infuse the body with spiritual energy!" At the moment when Long Tian felt that the spiritual energy vortex was almost the same, he directly controlled the vortex to stop, and then guided the strong spiritual energy to instantly infuse the body of the second girl!
In an instant, the two girls were enveloped by overwhelming aura, and the dantian was immediately irrigated with rich aura, even filled to full!

The second daughter immediately began to work on her dantian and began to practice quickly, and at the same time she allocated a part of her mind to quickly use her martial arts formulas!

Long Tian manipulated the aura to instill it on the second daughter bit by bit, and the second daughter could also appreciate Long Tian's good intentions, and it was also a desperate cultivation!

After half a day, the two of them burst out with halos, and then quickly absorbed the surrounding aura!

Long Tian laughed, knowing that Luo Xi and Hong Ying had succeeded!
He didn't pay any attention to the second daughter. What the second daughter needs at this moment is to practice quietly, stabilize her realm, and at the same time be familiar with her own aura and breakthrough martial skills!

Long Tian returned to the tent and rested for a while!
Until sunset, the sound of the battle came from the place where the two girls practiced. Long Tian knew that this was the first battle between the two girls after they broke through. Turned over and dived into the sea beside the island!
And the purpose of diving into the sea this time is very simple, that is, to go to the spiritual spring, the spiritual heart of heaven and earth, and the spiritual grass in the surrounding sea!

"Host! Continue to dive down. This is the center of the endless sea of ​​magic. The depth of the sea is tens of thousands of meters. You still need to dive for a long time! And the place where the soul of heaven and earth exists is deep underground, which is on the surface. The place closest to the depths of the earth is the place where spiritual energy, spiritual springs and even spiritual veins are most likely to be bred!"

"System! Then why do you think the spirit vein I obtained in Lingxiaotang is above the mainland? Isn't it in the deepest part of the surface?"

"Host! You have to know that this planet is the same as the Earth before you. The crust has changed for trillions of years, and no one knows where the spiritual vein was before!"
