In the past half hour, the six power-type mutants have evolved, and their already tall and strong physiques are now even more exaggerated, like an iron giant.

"Haha, I've gotten so strong!"

"Me too, I'm too strong."

"Teacher, what kind of panacea is this, how does it feel like it has been reborn." Ah Hu grabbed a stone, and when he held it gently, the stone was crumpled into powder.

"I don't know what the name of this fruit is, since you have safely evolved together, then rest in place, and the fire mutant will follow me into the cave." Liu Xing slowly stood up and pointed to a cave on the opposite cliff.

"Yes, Teacher!"

The four fire-type mutants were overjoyed and jumped directly onto the black head's back.

"Teacher, let's go too, we can help anyway." Ah Hu said eagerly.

"Hehe, the cave opposite is a flame cave, it's inconvenient for you to enter, Chiyan, what are you doing in a daze, let's go!" As he spoke, he pulled Chiyan to jump on the back of the black head, and controlled the black head to fly to the cave on the opposite cliff.

After entering the cave, Liu Xing said as he walked:

"There are some flame beasts here, everyone be careful. Chi Yan, you summon some flame lighting. ”

After speaking, he summoned the Qiushui Sword and let it clear the way.

After walking for a while, not a single flame beast was encountered, which may be the reason why Liu Xing hunted a few days ago, and now there are no new mutant beasts to replenish it.

The further you go inside, the more hot the air becomes, but fortunately, everyone is a fire mutant, and Liu Xing is also because of the fire aura in the dantian, everyone can bear it for the time being.

After walking for a while, he finally encountered a flame beast, Liu Xing controlled the flying sword and galloped away, splitting the flame beast in half in an instant, and a fire spirit stone rolled out.

"This is the Fire Spirit Stone, Chi Yan, this one is yours!" Liu Xing said lightly.

"Thank you Liu Xingda, Fire Spirit Stone! Ha ha! ”

Chi Yan quickly picked it up and looked at it in his hand with affection.

The other four fire-type mutants were envious and even more motivated.

The further you go in, the more flame beasts there are, and everyone has to be in a complete flame state, but Liu Xing doesn't have this ability, and many places on his clothes have begun to catch fire.

He gritted his teeth, holding two fire spirit stones in his hands, and began to absorb the fire spirit qi by running the Heaven Cultivation Decision. Only when he encountered the flame beast did he control the flying sword to attack.

"Teacher, you go out first, we can handle it ourselves." Zhao Liang said with some reluctance.

"It's okay, don't be distracted, although you are fire mutants, your attack methods don't have much effect on these flame beasts."

Liu Xing could have quit, he had already led everyone to find a lot of fire spirit stones.

"How did I forget about liquid metal? Maybe you can insulate it. ”

Liu Xing secretly said in his heart, and immediately took out the liquid metal ball from his back, and used spiritual power to drive it to evenly cover the surface of his body. I didn't expect it to be really effective, and the heat insulation effect was obvious, which really surprised him.

Not only is this liquid metal extremely resistant, but I didn't expect it to be insulated from heat. Liu Xing is not afraid of burning to death, the aura in his body can protect him from harm, but the spiritual power will be consumed relatively quickly.

Everyone has been walking unhurriedly, every time they get 3 fire spirit stones, they will leave one for Liu Xing, which is also everyone's tacit understanding, after all, this place is found by Liu Xing, and the flame beast was also killed by him, and the others followed to pick up a ready-made cheap.

After about 1,000 meters underground, we finally came to the end, where there was a huge magma cave with magma tumbling on the ground, and there was a stone platform on this magma cave with a strange sleeping animal lying on the stone platform.

"What kind of animal is this?" Zhao Liang asked in surprise.

"It looks a bit like a unicorn!" Chi Yan said with some surprise.

"Kirin?"

Liu Xing's consciousness swept and saw the appearance of this little guy on the stone platform a hundred meters away.

The dragon's head, antlers, tiger's eye, horse's body, dragon scales, and oxtail are all in one; This is the unicorn! And there are sparks coming out of this little guy's breath, and it is a baby fire unicorn.

Liu Xing was overjoyed, this is the mythical Rui Beast, one of the four divine beasts. Although it was still a young beast, its strength must be far above its own, but fortunately it was sleeping at this time.

Liu Xing controlled the flying sword to levitate 50 meters away, jumped by himself, used the air dance technique, glided onto the flying sword, and then lightly totoed, and slid for a while, preferably on the stone platform.

He carefully hugged the sleeping fire qilin, for fear of waking it up. Then he did the same and flew back to the crowd.

"Let's go back! Everyone knows what to do today! ”

Liu Xing said solemnly, he didn't want to be taken away by someone as soon as he got the fire qilin.

"Don't worry, teacher, we'll keep our mouths shut." Everyone nodded heavily.

"That's good, I won't treat everyone badly in the future."

Liu Xing didn't want to stay any longer, so he ran all the way out of the flame cave, beckoned the black head to fly over, jumped on the back of the black head, and returned to the top of the opposite mountain.

At this time, the fire unicorn has been put into the backpack by Liu Xing, and the backpack is also a military backpack, which can be bulletproof, waterproof and fireproof.

"Come on, I'm going back!"

Liu Xing beckoned to the six power-type mutants on the ground.

The strength of these mutants skyrocketed, and with one jump, they jumped onto the backs of blackheads more than ten meters high.

The black head suddenly felt struggling, stretched his wings hard, and finally flew back to the academy after more than ten minutes.

"That's all for today's class, I'll go back first, and everyone remembers their promises."

Liu Xing hurriedly walked out of the academy and returned to the clinic.

In the clinic, Uncle Kun took care of Uncle Qianbo carefully, which made Liu Xing a little embarrassed. He didn't know that Hu Die's medicine would make the red-robed old man unconscious for a few days.

"Young Master, you're back!" Cumber stood up to greet him.

"Well, is Uncle Qianbo better?" Liu Xing asked pretending to be concerned.

"The trauma is fine, but I'm still unconscious." Kunbo said with some concern.

"Don't worry, Uncle Qian's awakening is just a matter of the past few days."

"Well, I'm sure Big Brother will wake up." Cumber nodded and said.

"Then I'll go upstairs first."

Liu Xing returned to his room, he wanted to move the Spirit Gathering Array to Wang Shanshan's room, and then put the Fire Qilin inside.

It's just that he didn't have the knowledge of the formation, and he was afraid that he would break the formation by tossing blindly, so he had to take out the jade slip and find a way to arrange the spirit gathering array.

Fortunately, this Spirit Gathering Array is also the most common formation in the cultivation realm, and it is also a relatively basic formation, Liu Xing according to the ready-made formation, and then compared the method of arranging the Spirit Gathering Array, and remembered them one by one in his heart.

After everything was ready, he quickly withdrew the spirit gathering array, and then moved all the best spirit stones away, and set up a spirit gathering array in Wang Shanshan's room.

Liu Xing put down his backpack, carefully placed the fire qilin that was only 40 centimeters long in the spirit gathering array, and took out a handful of fire spirit stones and placed them around it.

After doing all this, he breathed a sigh of relief and muttered to himself:

"Little one, don't wake up right away! Get a good night's sleep for a few more days! ”
