Fantasy: The system takes me to refine the magic formula

Just after contacting Xue Tiankuang here, Long Tian felt that on the other side of the island, Hong Ying and Luo Xi seemed to be in a hard fight. He will send a message to himself, so Long Tian didn't show up, but just hid his breath, and appeared not far away to silently observe what happened!
Sure enough, the second daughter was facing the most powerful enemy she had ever fought in her life, a golden-toothed swordfish at the peak of level nine!

The golden-toothed swordfish is nearly [-] meters long, and its body is glittering with gold. There are fins made of steel knife on the back of its fins. Its huge and pointed mouth is spraying dark green poisonous gas at the two girls at this moment!
Although the second daughter was hundreds of meters away from the golden-toothed swordfish, the poisonous gas spit out from the swordfish's mouth swept over Hongying and Luoxi in an instant!
The Colorful Sky Heron immediately flapped its wings, and after dispelling the poisonous gas, silently retreated to the side and did not continue to participate!
Golden Tooth Swordfish also seemed to know that the second daughter was training, and there was another avian monster at the peak of level nine beside him, so he didn't want to fight with the two of them, and wanted to leave immediately!

However, the second daughter did not intend to let Jinchi Jianyu go directly, after all, this is a very good target for the battle!
Facing the unreasonable entanglement of the two daughters, the Golden Tooth Swordfish is also a little helpless. On the one hand, it already knows the cause of the whitetip mad shark's death, so it is just passing by here and does not want to cause trouble. On the other hand, it seems to feel that A certain invisible master has been watching him, but he can't leave, so he can only continue to fight!
After only a short while, Long Tian felt that the range and energy of the second daughter's control of aura had increased, and the Golden Tooth Swordfish seemed to be very cooperative with the second daughter. Many big moves were indeed terrifying, but if the second daughter can really fight Fighting with all your strength will also resist the big move, and if the extra attack damages the second daughter and cannot resist it, then it will also be resisted by the colorful sky heron to prevent the second daughter from receiving serious damage!

The battle lasted almost a day and a night. After observing for a period of time, Long Tian went back to restore his mental strength. With the Colorful Sky Heron around, Long Tian felt at ease!

The next day, the second daughter ran up to Long Tian in exhaustion but high spirits, chattering non-stop!

"Master! Luo Xi and I can fight against a level [-] monster! ~ Oh my God! I never knew that I could fight against such a powerful enemy! This is a leapfrog challenge!! And even the third peak of Xinjue is like this! fear!"

"That's right! Long Tian! You haven't seen my sister Hongying and I fighting hard! The attack power is simply earth-shattering! I never thought that my Big Five Elements Explosion Technique could produce such a terrifying effect! This time It was really cool to play!"

"Don't get excited, both of you, temporarily restore your own energy. In this day's time, have you improved your energy control?"

"That's right, master! There has been a lot of progress, and master! In the end, we beat the ninth-level monster Golden Tooth Swordfish away!"

"Yeah! It's a pity that you didn't see how it ran away!"

Long Tian was a little speechless when he heard the conversation between the two girls. How could the two of them drive away the peak monster of level nine? It must be because the other party saw the colorful sky heron and ignored it, so they took the opportunity to escape.

But Long Tian didn't break the words of the second daughter!Now that the two are in high spirits, Long Tian will not spoil other people's emotions!
"Long Tian! How is your recovery? Yesterday, I saw that you gave a level [-] double-tailed cold turtle aura and it was promoted to level [-]!! My God! It's unbelievable! I thought, can I trouble you? Fill my Four-Horned Flying Deer once and let it grow to level nine?"

"It shouldn't be a problem, but can I wait until I'm done?"

"Of course! That's great! Thank you Longtian! Hee hee!"

"You're welcome!"

Luo Xi kissed Long Tian's forehead very bluntly, which surprised Long Tian, ​​he never expected Luo Xi to have such an intimate move!
After kissing Longtian, Luo Xi seemed to realize that her actions were a bit inappropriate, but no one else saw it here, there was only one Hongying, and Hongying's thoughts were the same as her own, so it didn't matter!

"Sister Hongying! Let's go!" Luo Xi pulled Hongying and ran away!

Long Tian wiped the lip marks on his forehead, closed his eyes to restore his mental strength, and silently read the Prajna Paramita Heart Sutra!

A whole day's rest allowed Long Tian to recover his mental strength. Just when he opened his eyes, he suddenly felt a change in the system space!
Seeing that there was no one around, Long Tian stepped into the system space to check the situation!

It turned out that Gold Wing had successfully devoured the guts of the white-tip mad shark, and now it was at an important juncture of breakthrough, and it just so happened that the aura in the system planting space was extremely rich, and there was a spiritual vein in charge, allowing Gold Wing to successfully break through to the holy beast The Golden Eagle Roc!

The golden eagle roc is already at the top of Tianwu Continent!
At this moment, Gold Wing had just successfully broken through, and there was a burst of birdsong, which made Yinyue, Bimon and other monsters very envious!

Huofeng on the side said, "I never thought that following the young master is really the good fortune of these monsters! If he has been living in the forest of monsters, this Golden Winged Crazy Eagle will never break through! Look now, Already have the posture of a holy beast, really good!"
