Besides, if Mu Fan really taught him the complete time and space tricks of the Great Product, Mu Fan would already be his master.

Thinking of this, the old man of Tianji suddenly knelt on the ground and kowtowed respectfully to Mu Fan: "Disciple to meet the master!"

Mu Fan sat there, and after receiving the gift from the old man of Tianji, he said lightly: "Get up." ”

"Yes, thank you, master. The old man of Tianji said respectfully.

"Since you have entered my door, you have to abide by certain rules in the future, but my rules are very simple, there are only three!"

"First, don't kill innocents indiscriminately, second, don't kill each other, third, don't betray the teacher, as long as you do these three things, I won't embarrass you, and I will give you many benefits, once you violate any of them, I have several ways to make you disappear. Mu Fan said with a serious face.

Now that he has become a master and apprentice, this relationship is not ordinary, Mu Fan's requirements are naturally different, he doesn't want to cultivate a white-eyed wolf.

"Yes, the disciple follows the master's teachings. The old man of Tianji said respectfully.

Mu Fan nodded, and then said, "Well, you come here, I will pass on your time and space recipe now." ”

"Yes!" The old man of Tianji trembled with excitement when he heard this, and then bowed his head respectfully and stood in front of Mu Fan.

Seeing this, Mu Fan stretched out a finger and pointed it at the old man's brow.

Soon, Mu Fan's fingertips flashed with brilliant brilliance, as if there were ancient runes flickering in the brilliance.

The runes finally disappeared into the eyebrows of the old man of Tianji.

After about a cup of tea, Mu Fan withdrew his fingers.

And the old man of Tianji was still standing there with his eyes closed, he was contemplating the mystery in the formula.

Seeing this, Mu Fan did not bother, but sat on the chair and drank tea slowly.

Before he finished drinking a cup of tea, the old man of Tianji opened his eyes, and saw that he didn't say a word, so he knelt down in front of Mu Fan again, and said excitedly: "Thank you master for your kindness." ”

"Alright, get up. Mu Fan waved his hand.

The old man of Tianji stood up according to his words, then took off the ring on his finger, handed it to Mu Fan with both hands, and said, "Master, this is the disciple's space ring, all the things are in it, and please ask the master to smile." ”

"Just give me the map and the materials for Doodan. Mu Fan said, "I won't take the materials for Duerdan, and when I practice Duerdan, I'll give you one." ”

"Thank you, master, it was the heart of the disciple and the villain before, and I asked the master to punish him. The old man said.

"We don't know each other after all, you can understand if you are wary, the past is over, don't mention it again. Mu Fan waved his hand.

"Yes, disciple understood. The old man of Tianji nodded, and had a new understanding of Mu Fan, and at this time, he really recognized Mu Fan as a master, although Mu Fan was younger than him.

After thinking for a while, the old man Tianji said, "Where does the master live? It is better to move here temporarily so that the disciple can serve." ”

"There's no need to serve, but it's okay to stay, you can arrange it. Mu Fan nodded.

"Yes. The old man of Tianji nodded, and then asked his disciples to arrange the guest room.

For the scenes that happened later, Liu Yang and Naughty Mu have always been a little unable to react.

The two never thought that the old man of Tianji, who had not entered the oil and salt before, would become so respectful.

I didn't expect that Mu Fan could accept a sage as an apprentice.

Even if Mu Fan accepted a Tongtian Martial Artist as an apprentice, neither of them would be surprised, but this is a Sage!

One of the strongest people on the continent!

It's unbelievable, but it's all happening right under their noses, and they have to believe it.

It is precisely because of this that they have a new understanding of the mystery and power of Mu Fan.

At this time, they were even more determined that their decision to follow Mu Fan was the most correct choice.

............

......

After settling down, Mu Fan began to study the refining method of Du Erdan.

Although he doesn't need to cross Erdan now, the old man of Tianji doesn't need to cross Erdan if he has comprehended the complete time-space trick of the great product, but after practicing Duerdan, it means that he has entered the ranks of ninth-level Dan masters.

Therefore, Mu Fan didn't want to delay, he wanted to become a ninth-level pill pharmacist as soon as possible.

There are two main ingredients in Duerdan, and that is purple thundergrass and longevity fruit.

Purple Thunder Grass can increase the warrior's resistance to the power of thunder and lightning, thereby enhancing resistance and reducing the damage of thunder tribulation.

And the longevity fruit contains an abundance of heaven and earth vitality, and it can be seen from its name that eating it can lead to immortality.

Of course, immortality is an exaggeration, but a martial artist who eats the immortal fruit will have a substantial increase in strength and longevity.

Both of these fruits are extremely rare and are the most truly rare herbs of time.

Moreover, the attributes of these two fruits are mutually reinforcing, to the point that water and fire are incompatible.

Therefore, if you want to refine and fuse the two fruits, it will be extremely difficult, and there will even be a risk of frying.

If this is a real fryer, it will not be a trivial matter.

The energy of the two fruits is extremely powerful, and once it explodes, it can directly destroy any Tongtian martial artist, even if the Nirvana master is not careful, he will be injured.

Mu Fan went through all the points and precautions in his mind, and after making sure that there were no omissions, Mu Fan took out the Eight Desolation Ding.

However, Mu Fan was not in a hurry to refine the Du'er Dan, but began to refine other eighth-level pills.

There is only one pair of medicinal materials for Du Erdan, and once you fail, if you want to practice Du Erdan, you don't know how long it will take.

Therefore, Mu Fan first used some eighth-level pills to practice his hands.

As for the eighth-level medicinal materials, Mu Fan has a lot of them in his hands, and even if he is useless, he is not afraid at all.

And in this way, Mu Fan can adjust his state to the best, which can be regarded as a warm-up.

After refining three eighth-level medicinal materials in a row, Mu Fan felt that he had truly entered the state, and only then did he take out all the medicinal materials of Du Erdan.

There are not many medicinal herbs, only nine kinds, but each one is extremely precious and extremely rare.

Mu Fan adjusted the temperature of the flame, and then put one of the medicinal herbs into the Dan furnace.

Although Mu Fan could smelt several medicinal materials at the same time, at this time, he didn't dare to be careless, but chose the same.

The refining of the medicinal materials in the previous one was all extremely smooth, and each medicinal material took about a day.

On the eighth day, Mu Fan began to refine the Immortal Fruit.

After the Immortal Fruit entered the Dan Furnace, the flames in the Dan Furnace suddenly rose, and the temperature began to rise suddenly.

The reason why this happened was because the Heaven and Earth Yuan Qi was also a kind of energy, and the Yuan Qi of the Immortal Fruit actually burned under the action of the flames, so the flames became unstable.

Seeing this situation, Mu Fan's face changed slightly, but his reaction was also extremely fast, and then he reduced the output of the Colorful Sacred Flame and began to lower the temperature of the flame.

Under Mu Fan's control, this twist and turn can be regarded as a thrill, and the longevity fruit is fortunately not a big problem.

But the matter did not end there, the immortal fruit was constantly floating in the Dan furnace, and the energy in it also fluctuated.

And with the fluctuation of the energy of the immortal fruit, the flame temperature in the Dan furnace is also constantly changing.

Mu Fan didn't dare to take it lightly, his divine sense was fully expanded, closely paying attention to any changes in the Dan furnace, and then adjusting the temperature of the flame according to the subtle changes in it.

This kind of high-intensity work lasted for ten days at once.

Ten days later, the entire Immortal Fruit was completely refined, turning into a few drops of emerald green liquid.

In the liquid, the brilliance flows, and the abundant energy fluctuations emanate from it, and with the fluctuations of the energy in it, you can even see the ripples in the space.

"The energy of the Immortal Fruit is so strong, swallowing the Immortal Fruit alone is infinitely effective, I really don't know what kind of situation it will be like to practice the Crossing Erdan!"

After refining the Immortal Fruit, Mu Fan was ready to refine the Purple Thunder Grass.

The purple thunder grass contains the power of thunder and lightning, and as soon as it encounters the flames in the Dan furnace, it is like the thunder of the sky has moved, and the entire Dan furnace has vibrate.

The purple thunder grass was covered with the power of thunder and lightning, and it was growing medicinal herbs, constantly trembling, and there was a crackling sound on it, which made people's scalp tingle.

And the power of thunder and lightning of the Colorful Holy Fire and the Purple Thunder Grass seemed to have the effect of protecting and catalyzing each other, and when the two were put together, they all became unstable.

Mu Fan's face really changed now, because of this situation, he would definitely blow up the oven at any time.

This hasn't made the Purple Thunder Grass and the Immortal Fruit fuse, I really don't know what kind of scene will happen when the two merge, it must be even more difficult.

However, Mu Fan didn't think much about it, he put all his mind on the purple thunder grass, wanting to find the best flame temperature.

If the temperature of the flame is high, it will interact with the Purple Thunder Grass and directly detonate the energy in the Purple Thunder Grass.

If the flame temperature is low, it will not be able to refine and quench the Purple Thunder Grass, and it will not have any effect at all.

The temperature is relatively well controlled, not one more point, not one less point.

This time is definitely the most difficult moment for Mu Fan's alchemy.

In just a short period of time, a lot of sweat broke out on Mu Fan's forehead, and his face became pale.

This is the result of a drastic drain of consciousness.

Alchemy, however, does not consume much vitality, but consumes the most divine sense.

Especially at this time, Mu Fan is required to be extremely accurate!

This kind of high-intensity consumption is not something that everyone can afford.

This is also Mu Fan, his divine sense is much stronger than that of ordinary pill pharmacists, if he changes to a pill pharmacist, he will already be tired at this time, and he can't even control the situation in the pill furnace, causing the furnace to explode.

One day, five days, ten days, twenty days......

It wasn't until twenty-five days ago that the Purple Thunder Grass was completely refined.

It's not that the level of Purple Thunder Grass is higher than that of Immortal Fruit, but because Purple Thunder Grass is more unstable, so it is more difficult to refine.

After all the medicinal herbs were refined, Mu Fan did not relax because of this, because the challenge had just begun.

Quenching medicinal materials is only the first step, and the most difficult thing is the fusion of various medicinal materials, especially the fusion of purple thunder grass and longevity fruit.
