Zhou Su was very happy to accept Fang Ya and the two as apprentices, because in his opinion, the alchemy talents of these two people were slightly better than him.

Let's take Fang Ya as an example, Fang Ya is only 29 years old now, she is already in the late stage of the 7th Order Demon Sect, and her alchemy level is also purple 1 pattern, and her own talent has also reached the level of purple 3 lines, with her continuing to cultivate like this, at most ten years, Fang Ya will definitely break through to the 9th order Demon Saint, and the alchemy level can also reach purple 9 lines.

But this is an almost perfect life in the eyes of ordinary people, but in Zhou Su's opinion, it is a bit too wasteful.

Fang Ya's talent is far more than that!

Now under the guidance of Zhou Su, it is only a matter of time before he breaks through the 10th Order Demon Emperor in the future, and the level of alchemy is under Zhou Su's teaching, it is not difficult to reach the level before Zhou Su, the only thing that is a little difficult is that there is no (immortal) elixir here. Only by breaking through the 10th Order Demon Emperor and feathering into an immortal can you continue to improve.

Cai Congyun is now 19 years old, and his cultivation is the peak of the third-order great magician in the later stage, and he is about to break through the fourth-order magician, and his alchemy talent is also slightly higher than that of Zhou Su and Fang Ya. If they cultivated step by step like this, their final achievements would be the same as Fang Ya's, a 9th-order demon saint and a purple 9-pattern alchemist, but now with Zhou Su's teachings, the future of the two of them would be very different.

"You two sit down first. I'll teach you how to control the Dan Fire in your body more proficiently. ”

Zhou Su looked at the two girls and said with a smile.

When the two heard this, they also sat cross-legged on the futon. Now that they have worshiped Zhou Su as their teacher, they have to show their attitude towards the master, and they can learn the method of alchemy outside the furnace, so it is also a great opportunity for them.

Zhou Su did not delay, first informed the two of them of the mantra and cultivation method of the fire fight, and then summoned the green Danhuo to explain it carefully to the two of them.

After more than an hour, Zhou Su stopped, looked at the two people opposite him who seemed to have an understanding, and asked, "Do you understand?" If there is anything you don't understand, just ask, so that I can explain it to you, so that your cultivation will be better and faster." ”

"Master, why is your Dan Fire green, while mine is the pale yellow of ordinary flames?"

Cai Congyun summoned his Dan Huo and appeared at his fingertips, and asked curiously at Zhou Su.

Cai Congyun's Dan Huo is indeed as said, the color is the same as ordinary flames, it is pale yellow, and it is obvious that it is a garbage flame, and there is no Zhou Su's green flame cow pen.

Although Fang Ya didn't speak, she also summoned her own crimson Dan fire to linger around her fingertips, looking at Zhou Su and waiting for Zhou Su's answer.

Zhou Su glanced at the flames of the two of them, and said with a smile: "My Dan Huo belongs to the Heaven and Earth Alien Fire, and your Dan Fire is an ordinary flame triggered by the alchemy method, this is the reason." ”

"Master, what is the strange fire of heaven and earth!" Cai Congyun asked again.

"Heaven and Earth Strange Fire, as the name suggests, is the fire of heaven and earth born in various strange mountains and valleys in heaven and earth. For example, the fire in the center of the earth is born in the low molten slurry, and it is like the cold flame in the bitter cold land, and then it is like the sea flame born in the bottom of the sea, and so on. These different fires born between heaven and earth are the different fires of heaven and earth. After fusing the different fires of heaven and earth, not only can you improve your personal combat effectiveness, but you can also be of great help to the alchemist. If an alchemist has a good Heaven and Earth Alien Fire in hand, alchemy will be much simpler and easier, and it will also be easier to impact a higher level. Zhou Su saw that the two were curious, so he introduced.

"Then can we get the Heaven and Earth Strange Fire?"

Cai Congyun listened to Zhou Su's words, and his eyes showed a look of yearning, if he also had the different fires of heaven and earth to alchemy, how good would it be!

"But you can, but the different fires of heaven and earth are not so easy to get, and if you are not careful, you will be eaten by the different fires of heaven and earth and burned to ashes. Zhou Su said with a smile.

"I'm not afraid, Master, when will you take me to find a Heaven and Earth Fusion of Different Fires?" Cai Congyun looked at Zhou Su and asked with a smile. Although Zhou Su made her very unhappy before, but now it is different, his own master worships him as a master, so he is his apprentice, and it is natural to ask for some benefits.

"Xiaoyun!" Fang Yajiao shouted.

The different fires of heaven and earth can be heard from Zhou Su's words, isn't this embarrassing for Zhou Su?

"Heaven and earth are unavoidable, what kind of fire do you say you have? And the heaven and earth fire in this world is still a little worse, and the increase brought by being used as a Dan fire is not very large. Zhou Su pinched his fingers and said with a smile.

The flame of life in Zhou Su's hand is still a heaven and earth fire obtained by chance before he reached the true immortal, and he retained his fire in the Nine Phoenix Ring before he died, and Cai Congyun reintegrated it in a hundred years when he was refining the pill, but the power it exerts now is less than one-ten-thousandth of its perfect state.

"The increase is not big, this is not a problem, is it a little bit of an increase, isn't it, Shizu~"

Cai Congyun's eyes lit up when he heard this, Zhou Su said this, which means that he can get the fire of heaven and earth, and immediately ignored Fang Ya on the side, and said coquettishly.

Zhou Su also smiled when he saw Cai Congyun's expression, and said, "Let's wait until you break through to the 5th-order Demon King Realm." ”

"Oh, okay. Cai Congyun suddenly fell down and replied in a low voice.

Originally, I thought that I could get the different fires of heaven and earth, but now I am empty and happy.

But soon, Cai Congyun recovered again, Zhou Su said, after the 5th Order Demon King Realm, that is, Zhou Su may take her to find the Heaven and Earth Strange Fire, so she didn't stay here for long, turned around and left here, ran to the cultivation room in her room on the third floor, and couldn't wait to start cultivating.

"Master, Xiaoyun is such a character, don't be angry with her. ”

Fang Ya looked at Cai Congyun who ran upstairs and said to Zhou Su.

Zhou Su smiled, "She's such a cute girl, why am I angry with her?"

"It's good not to be angry. ”

Fang Ya breathed a sigh of relief, in her mind, a person as arrogant as Zhou Su might be a little displeased when she saw Cai Congyun with such a character, but now it seems that there is no need to worry.

Neither of them spoke, and the room suddenly fell into silence at this time, which made the atmosphere make Fang Ya feel a little uncomfortable, and suddenly Fang Ya felt Zhou Su's current cultivation, thought of something, and opened her mouth to break the calm and said: "Master, you have broken through to the early stage of the Demon King now, do you plan to participate in this year's outer door competition? This is a good opportunity to be promoted to an inner disciple." ”
