After getting off the boat, Liu Xing beckoned to the black head with a dark face and left alone.

Hu Die took dozens of students and the unconscious merman to the commuter bus of the academy with a straight face, and the other students did not dare to touch their heads, so they closed their mouths and silently returned to the academy. It's just that there is more speculation in their hearts.

Liu Xing returned to the clinic, went upstairs alone, and took out the sword box in the cabinet, which contained twelve exquisite flying swords, which were complete sets of flying swords, each as smooth as autumn water, and also exuded a faint brilliance.

"These flying swords should have a golden aura!" Liu Xing took out a handful and put it flat on his knees, running the Heavenly Cultivation Technique, and the golden aura in the flying sword was slowly inhaled into his body, and then dipped into the light cluster of the dantian.

"Sure enough." Liu Xing opened his eyes and saw that the halo of the flying sword had dimmed, so he had to stop, such a good flying sword was absorbed by himself with golden aura, and some of the gains outweighed the losses.

He carefully put the flying sword into the sword box, and then put the sword box into the spirit gathering array, hoping that they could be nourished by the aura and slowly recover.

Liu Xing took out a bunch of unknown metals that he had collected before, tested them one by one, and found that a few of them could be absorbed by him, such a good opportunity, he was willing to let it go, and absorbed all the metallic aura contained in a few unknown metals.

These metals, which used to emit a dull halo, are now dull, as if they have become mortal iron. Liu Xing used his divine sense to check the five light clusters of his dantian, and the light clusters seemed to be larger, no longer so white, and there were several colors mixed in them.

Liu Xing turned his wrist, and a fireball appeared in the palm of his hand, and the fireball also changed a little, it was no longer orange-red, and the flames seemed to become more aggressive. His eyes ached.

"I didn't expect to add a few other aura, and the spell became more powerful, but the casting process seemed to be a little slower." Liu Xing nodded with satisfaction, the aura in his body was a little mottled, so the conversion of aura was a little lagging behind. It's just that he is not worried, and he can return to his normal speed by practicing slowly.

"Since metals can be absorbed, so can other elements." Liu Xing couldn't sit still, walked out of the clinic, and called the black head to fly to the mountains and forests.

The blackhead flew hundreds of miles and found a place where the trees were more dense and fell. Liu Xing pulled out his battle knife and slashed at the ground with his spiritual power, and a half-meter-deep crack appeared on the ground. He didn't hesitate, jumped straight down, sat down cross-legged, and then pressed his hands on the ground, running the exercises, trying to see if he could absorb the earth's earth aura.

A lot of aura around him slowly gathered and entered his body, Liu Xing frowned, this is not good.

"Blackhead, you buried me!" Liu Xing didn't want the aura between heaven and earth to interfere with him.

The black head tilted his head and looked at Liu Xing with some puzzlement.

"You stupid, grab some dirt with your claws and bury me!" Liu Xing accentuated his tone.

The black head didn't hesitate any longer, grabbed a lot of soil around Liu Xing, and buried Liu Xing.

"Ahem, it's okay. You are on guard around me, and I want to cultivate with peace of mind. Liu Xing shouted to stop him, and now he only had his head exposed.

The black head nodded, really vigilant and vigilant around.

Liu Xing breathed a sigh of relief and continued to cultivate. Finally, some pale yellow aura entered his body and landed on the light mass in the dantian, these pale yellow aura seemed to be heavier than the simple aura, and slowly soaked into the core area of the air mass, and merged with the golden aura into a core air mass.

The moon is slanting to the west, with a posture of exuberance. The moon was darkened by the chirping of summer insects, and in the night sky, the stars were like light frost, and they were bleak and desolate.

Liu Xing exhaled a breath of turbid air and jumped out of the dirt pit. He just tested whether he could absorb the earth aura in the soil, and the result was quite satisfactory. It's just that the cultivation speed is not fast, and it is much slower than absorbing the spiritual energy between heaven and earth.

"Go on, go on, Wood Aura." Liu Xing found a big tree, dug a hole in the tree, stuffed himself into it, and then sealed the hole.

Time passed little by little, the stars shifted, the east was white, Liu Xing came out of the tree hole, and now there were a few traces of green mixed in the air mass of his dantian, which continued to swim on the surface of the air mass, and the air mass seemed to be more vibrant.

It's just that this tree, which was originally hundreds of meters high, has lost its vitality, and the leaves have fallen one after another.

"Looking at ordinary trees, there is not much wood aura, and now the five elements aura is still short of fire aura, this is more troublesome, ordinary flames must have no aura, unless it is earth fire." Liu Xing lowered his head and pondered.

The blackhead screamed and pointed to his stomach with his wings.

"Foodies are hungry! Let's go! Liu Xing jumped on the back of the black head, and the black head led him to the sky above the kiwi fruit tree last time.

"Do you still want to eat this red fruit? I'm not afraid to turn into a monster! Liu Xing patted the black head's neck.

The blackhead swooped down quickly, and the eagle's beak aimed at a red fruit and pecked fiercely. When a fruit fell into its mouth, the strange tree, of course, was not reconciled, stretched out a lot of roots, and flew away at the black head.

Liu Xing had already prepared, and the eight flying knives were aimed at the galloping roots, and with a few swishing sounds, the eight roots were cut off.

"Is that what it takes? Come again!" Liu Xing recalled the flying knife and said with a sneer.

The roots of the trees that had fallen to the ground sank into the ground in an instant, and vanished. It's just that it didn't launch any attack on Liu Xing, it already had a spiritual intelligence, and it knew that it couldn't be beaten and ignored it.

Liu Xing smiled secretly in his heart, and used the telephalation technique to pick a few fruits. He was going to try it out to see if the fruits had any wood aura.

The black head found a safe convex stone on the edge of the cliff, and lay on it himself, slowly digesting the spiritual power of the red fruit. Liu Xing also sat on the ground on the back of the black head, running the Heavenly Cultivation Technique, holding a red fruit in each hand. The attraction burst out from the Lao Gong acupoint in the palm of his hand, enveloping the fruit in the palm of his hand, and the thin wood aura slowly merged into his dantian from the fruit.

"It's so unexpected, I didn't expect that this red fruit not only contains a rich wood aura, but also a few traces of fire aura." Liu Xing raised his eyebrows, happy and happy.

Now his dantian is finally full of five elements of aura, the five clouds of the dantian are dripping and rotating, and several auras are mutually restrictive, and there is a feeling of endless life.

It's just that their respective auras are not balanced, and they don't run smoothly, especially the fire aura.

The red fruit in his hand had dried up, and Liu Xing didn't want to continue picking the fruit, but saw that not far from the convex stone of the mountain cliff came out of the cave, and there was green smoke coming out of the cave from time to time.

"No, there is a fire in that cave!"

Liu Xing said secretly with a little joy. Seeing that the black head under his feet was still sleeping and digesting the spiritual power of the red fruit, he had no choice but to go alone.

Liu Xing jumped up, and a dance technique was unfolded, and the person slowly floated in the air, and then opened his hands, and the palms of his palms spewed out air, and they slid towards the cave.

The effective distance of a dance technique is only 50 meters, and the cave is more than 100 meters away from him, several times he fell on the edge of the cliff, he used his feet to exert force, kicked hard, repeated several times, and finally arrived at the entrance of the cave.

He hesitated for a moment as he stood at the entrance of the cave, then threw a fireball into it, and the inside was bright. There is nothing in the visible area.

Liu Xing slowly entered the cave with courage. A flame appeared in the palm of his hand, which he extravagantly used as illumination. I walked for more than half an hour, and I didn't go to the end, and it was getting hotter and hotter to go inside.

Just as he was about to turn back, a flaming stone monster jumped out, the stone monster looked like a wolfdog, but it was all made of stone, and there were flames from the cracks from time to time.

Seeing this, Liu Xing pulled out his battle knife like a conditional launch, and couldn't help but say, between the lightning and flint, a knife split the stone wolf dog in half.

With a "ding" sound, a fiery red gem the size of a pigeon's egg rolled into Liu Xing's feet.

"This may be the so-called Fire Spirit Stone!" Liu Xing sensed the aura of the fire ruby slightly, and said with some uncertainty, after all, he had never seen any fire spirit stones.

Since the flame monsters in the cave mansion had fire spirit stones, of course Liu Xing would not let them go. Keep exploring.

The strength of these stone monsters is unknown, but they certainly do not surpass the third-order mutants. Otherwise, no matter how sharp Liu Xing's war knife was, it would be impossible to split one in half with one sword.

Liu Xing walked forward slowly, killing a lot of stone monsters with flames, all kinds of forms, and a lot of fire spirit stones were also collected, but he didn't continue to explore, it was because the air was getting thinner and thinner, the temperature was getting higher and higher, and there was a lot of smoke in the air, which made his eyes a little smoky and couldn't open them.

Walking out of the cave, Liu Xing didn't see the black head on the convex stone, and when he raised his eyes, he saw that this thing was still fighting with the strange fruit tree, and he was fighting back and forth.

Liu Xing let out a long roar, the black head looked down, and found Liu Xing outside the cave, it reluctantly glanced at the red fruit, swooped, came to Liu Xing's side, and took him back to Yuezhou City.
