It didn't take long for the two figures to leap to the top of the mountain and stop at the edge of the flat ground.

"Mentor Bai, I've got a helper! he can help me fix that hole......

After Mo Chen came back, he scratched his head with a smile and introduced to Bai Yunfei: "Tutor Bai, this is Tutor Xiao from the third class of the fifth grade of the Earth Department. ”

Then he said to the person beside him, "Mentor Xiao, this is our Mentor Bai. ”

The man smiled slightly, hugged his fist at Bai Yunfei and said: "Hello Tutor Bai, Xiao Nan is also the tutor of the academy, and I have admired Tutor Bai's name for a long time, I will see you today, hehe...... Sure enough, he is a heroic boy. ”

This person looks about thirty years old, dressed in brown clothes, about 1.8 meters tall, with short black hair, an angular face, and a relatively ordinary appearance, but he exudes a sense of maturity and stability, and his eyes are gentle, so he should be a very good person to get along with.

Bai Yunfei replied: "Mentor Xiao has won the award, where can I talk about any big names...... This time, I'm going to trouble Mentor Xiao. ”

Xiao Nan waved his hand and said with a smile: "Mentor Bai is polite, it's nothing to help a little, no need to say thank you, by the way, what are you doing?"

At this time, he had already seen a pile of caves dug out of the mountain wall, and he couldn't help but look strange.

Mo Chen replied first: "This is the refining cave of our refining class, and we will refine here in the future." ”

"......" Xiao Nan was obviously stunned for a moment, and then smiled, "Uh...... This, Mentor Bai, your refining class...... It's really special. ”

Bai Yunfei said: "Hehe, let Tutor Xiao smile, the main thing is that there is something special when refining weapons, and if you are in the classroom of the academy, I am afraid that it will affect other students, and this kind of environment is also more suitable for refining weapons." ”

Xiao Nan nodded: "I see, is there anything I can help with?"

He looked at the mountain wall, and found that there were eight caves, all dug up, so what did he tell himself to do?

"Mentor Xiao, here, here. Mo Chen pulled him embarrassedly, walked to the passage he blasted out, and said embarrassedly, "This...... I hope Mentor Xiao can help me block it, hehe, please Mentor Xiao!"

Due to the angle just now, Xiao Nan didn't see the situation of this hole, and when he saw it at this moment, he couldn't help but be stunned, and then showed a hint of surprise, and said with a smile: "This, you made it......, right? Why are you so impertinent? When will your reckless character change?"

Mo Chen scratched his head and smirked.

Looking at the conversation between the two, it seems that the relationship is good.

Xiao Nan glanced at it casually, then nodded and said, "Well, no problem, it's just a trivial matter, leave it to me." ”

Mo Chen's expression was overjoyed: "Thank you Mentor Xiao!"

Xiao Nan smiled, walked to the edge of the cave, stretched out his right hand and pressed it on the mountain wall.

After that, he saw a burst of orange light flickering around him, and a strong soul power emanated, and then attracted the Heaven and Earth Yuan Force within a radius of 100 meters, and countless orange Earth Yuan Forces condensed from the void, enveloping his entire person in it.

Bai Yunfei raised his eyebrows slightly, and secretly exclaimed in his heart: "What a strong earth element force!"

The earth element power that was condensed outside Xiao Nan's body gave Bai Yunfei a feeling of being as stable as a rock and indestructible - this Xiao Nan's strength had reached the peak of the late stage of the Soul Venerable, and his long and strong soul power was by no means comparable to the ordinary late stage peak Soul Venerable, could it be...... He has already reached the realm of the Soul Emperor who is about to advance?!

A few seconds later, Xiao Nan's eyes in the orange mang's package stared, and his right arm pressed on the mountain wall shook slightly, and the orange mangs swelled, and they all followed his arm and poured into the mountain wall in front of him!

"Buzz!!"

I don't know if it's an illusion, Bai Yunfei faintly heard a buzzing sound, and this sound ...... From the feet!

It's like the trembling of the mountains!

At the same time, after the powerful earth element force poured into the mountain, the part of the mountain top of nearly 100 meters faintly revealed a faint orange glow, and Bai Yunfei even felt that the ground under his feet seemed to have life, and there was a rhythm like a heartbeat.

"Click, click......"

A slight sound came, only to see the passage that was blasted out by Mo Chen, the rock at the entrance of the cave on the other side of the mountain suddenly seemed to come to life, a burst of rolling and wriggling, in a few blinks of an eye, the sand and soil surged, the rock rolled upside down, the other end of the passage was directly sealed, turned into a cave about twenty meters deep, the end of the sealed, it was as smooth as the wall, and even reflected the long orange man, which seemed extremely solid.

And what has changed is not only Mo Chen's refining cave, but at the same time, the soil and stones on the top of the entire mountain are trembling slightly, like ripples on the surface of the water, which lasted for several minutes before gradually stopping.

The light gradually dissipated, revealing Xiao Nan's figure again, he slowly withdrew his right hand, breathed a sigh of relief, the surging soul power in his body gradually disappeared, and changed back to his previous appearance, it seemed that he was not the slightest tired.

Bai Yunfei and the others subconsciously looked at the mountain wall in front of them again, and found that it seemed to be no different from before, but if they looked closely, they would find some special places.

Looking at it as a whole, it seems to be ...... Got harder?

Moreover, the eight high-altitude refining caves seemed to be more 'neat' than before, and the cave seemed to have become a little more spacious, and the walls of the cave were smooth and slightly glowing with a solid light.

Obviously, in just a few minutes, Xiao Nan changed the soil quality of the entire mountaintop!

Bai Yunfei was secretly surprised, he could do such a weightless earth element force control, the strength of this Xiao Nan mentor should not be underestimated.

Xiao Nan walked back in front of Bai Yunfei and said with a smile: "Mentor Bai, look like this...... Is it okay?"

Bai Yunfei retracted his gaze and hugged his fists gratefully: "This, thank you so much Brother Xiao, in this case, as the refining place of my refining class, it seems that there is absolutely no problem, thank you very much!!"

Xiao Nan smiled and said: "Since you call me Brother Xiao, then you don't have to be so polite, Brother Bai, if you need help in the future, just look for me, if you can do it, you will never refuse." ”

Bai Yunfei said 'heroically': "Okay! Then I'm not welcome, Brother Xiao will have a place for the younger brother in the future, just speak!"

......

After a few more simple chats, Xiao Nan said that there were still a few students to tutor, so he said goodbye and left.

This Xiao Nan's tutor gave Bai Yunfei a very good impression, and the little 'prejudice' against the academy tutor because of the fire tutor Zhou Yu before has also disappeared.

Bai Yunfei glanced up at the seven academies around him, waved his hand, and said: "Okay, since the refining cave has been completed, this will be our 'base area' in the future, now, everyone will come to my refining cave, and I will briefly explain to you the basic situation of refining weapons, as well as the most basic method of fire refining control." ”

Hearing him say this, the people around him were all in high spirits - after being busy for so long, they were finally going to really start learning alchemy!!

With anticipation, the students followed behind Bai Yunfei and walked into the refining cave......
