Fantasy: The system takes me to refine the magic formula

Long Tian watched the two girls adapting to the aura from a distance, while he let the system scan the surrounding security situation, and at the same time check if there were any treasures of heaven and earth, but the system scanned for a long time, but there was nothing, not even a high-level one. There is no Warcraft at all!
This answer was expected by Longtian. After all, this is the outermost part of the endless magic sea. There are no high-level monsters and no treasures of heaven and earth. The situation in the endless magic sea is actually similar to that of the monster forest. If there is a genius treasure, then it must be accompanied by high-level monsters guarding it!
Long Tianyuan watched the two daughters kill the spirit fish, countless spirit fish floated on the sea after death, the second daughter waved the spirit fish into the storage ring, and returned to Tianwu Continent in the future, looking for a pawnshop or something Just exchange it!
After a while, the two girls returned to Long Tian's side again.

"How is it, are you used to it?"

"No! Master, I think we should enter the middle area of ​​the endless magic sea as soon as possible. The spirit fish around here are the most basic, without brains! They saw me zooming in, and they had no intention of dodging at all. I even charged up, I split open a spirit fish to see its guts, but it turned out to be only as big as a small fingernail, it would be meaningless to kill it any further! I just barely know how to use my spirit energy!”

"Hehe! There is really no need to stay here anymore, let's release the monsters and move forward! It will probably take a few days to fly to the next floor!"

"it is good!"

The three of them flew quickly on the back of the Golden Wing and the Colorful Sky Heron again. During the period, they saw two small islands and did not stay on them!

Gold Wing and Colorful Sky Heron have been running wildly for ten days!Finally, they got through the periphery and entered the second floor, but the level of monsters on the second floor still disappointed Long Tian and the others. The three had to move forward again. After flying like this, they flew for more than half a month!
On this day, Golden Wing and Colorful Sky Heron were speeding up, when suddenly the system prompted: "Host! Stop! Right below the deepest part of the ocean, two level [-] monsters are fighting, and they are fighting for the God Star Grass!"

"What! God Star Grass? Why is there God Star Grass in this sea!" After Long Tian heard the words of the system, he immediately stopped Jin Yi and Colorful Sky Heron! ~
"What's wrong, Long Tian!?"

"There are two ninth-level monsters fighting in the sea area below! They are fighting for the God Star Grass! I want to go down and have a look!"

"What! God Star Grass?" The second daughter hesitated to Long Tian's words!

"It's true! I also know that God Star Grass usually grows on cliffs, but it's normal for God Star Grass to exist in this ocean! You two are waiting for me here! I'll go and see!"

"Master! I'll go with you!"

"No! There are two ninth-level monsters below! The water-type monsters in the endless sea of ​​magic are much stronger than those in the monster forest. The ninth-level monsters here can fight against the ninth-level intermediate monsters in the monster forest! If there are two You two can't protect yourselves if you're only fighting against monsters at the peak of level nine!"

"This..." Both Luo Xi and Hong Ying knew that what Long Tian said was true, but both of them were a little worried about Long Tian, ​​and wanted to go into the water with Long Tian!
"Be obedient! Wait for me here!"

"Okay sir!"

Long Tian let Jin Yi stay in the sky to protect the two girls, and two peak level nine monsters protected the two girls, so that Long Tian could rest assured, then plunged into the water, let the system block his own breath, and then quickly dived into the bottom of the water!
The moment Long Tian entered the sea, he quickly activated the aura barrier to protect himself from being penetrated by the sea water. At the same time, he didn't know whether the huge spiritual power contained in the sea could be used by monks to practice, and he was in a hurry at the moment. So there is no question of studying sea water, just go crazy and dive directly!
As expected of the endless sea of ​​magic, Long Tian didn't know how long he had been diving, nor how deep he had dived, but he kept diving, and finally in the darkness, he saw two luminous bodies suddenly colliding with each other!
Then there was an explosion sound, and Long Tian immediately got ready to face the huge waves!

The energy waves colliding between the giant wave and the ninth-level monster's ultimate move caused Long Tian to churn in the deep sea for a long time. When Long Tian regained consciousness, he saw two white light cannons colliding again!
This time Long Tian didn't just catch him, he directly used Shengtian Finger Power and Potian Fist. His strength in the middle stage of the Mahayana period can still stabilize Yu Bo, who is fighting against a ninth-level monster!

And the two level nine sea beasts seemed to have gone crazy, they didn't care about Long Tian's appearance, they were already fighting each other desperately!

Long Tianxia dived not far from the monsters, and finally saw clearly what the two battle monsters were!
It was actually a Hydra of the water system and an iron sea centipede fighting!
The first moment Long Tian saw these two monsters, he actually had goose bumps all over his body!

Hydra is okay, I have seen it in the World of Warcraft Forest before, but this is the first time Longtian has seen the iron centipede, and it is still in this endless sea of ​​magic!

The entire iron centipede was a full 30 meters long, covered with tentacles more than one meter long, and both the iron centipede's body and the iron centipede's tentacles were segmented, making Long Tian's scalp numb!
