As soon as Du Fan's mind turned slightly, he hugged his fists and wanted to open his mouth to say the words he had brewed earlier.

However, the Maple Leaf Sect Master waved his hand directly, smiled kindly, and said something that made Du Fan extremely depressed and speechless.

"Elder Du has made great contributions this time, and the gains in the Hundred Flowers Valley don't have to be handed over to the sect, just keep it for yourself, just take out the twenty-three towering spirit fruits.

As for the other things, Elder Du must not be polite, it should all be a little bit of the heart of the Qixia Sect. ”

Okay, although Du Fan was a hundred unwilling in his heart, but the old fox of the Maple Leaf Sect Master had all said everything about this, what else could he do?

What made him squirt blood the most was that the Maple Leaf Sect Master actually said the numbers very clearly, completely dispelling Du Fan's idea of secretly leaving two plants, and under gritting his teeth, he could only take out the towering treasure tree directly.

Next, in the corner of Du Fan's eyes, an elder plucked the towering spirit fruits one by one with a look of ecstasy in front of him, and sealed them in wooden boxes of extraordinary quality.

Du Fan's heart was dripping blood, but he still maintained a faint smile on the surface.

He found that when these old guys saw this towering treasure tree, to be precise, it was the towering spirit fruit on it, and all their eyes were wide open, their eyes were shining, and their faces were excited and excited, as if they were looking at the future twenty-three Jindan stage monks of Qixia Sect.

Du Fan sighed lightly, and now he could only retreat to the next best thing, and put forward the idea of asking for the towering treasure tree to go back to study.

Without the slightest hesitation, the Maple Leaf Sect Master agreed very generously, and the elders and worshippers had no intention of stopping it, everyone knew that once the Heavenly Treasure Tree left the Hundred Flowers Valley, it would have no value.

In the end, Du Fan took the bare towering treasure tree back into the Qiankun ring, and exchanged a few words with the old guys of Qixia Sect, and after learning that Chen Ru would go to Qixia Ancestor to see him later, he took his leave.

After leaving the main hall, he went straight back to his own courtyard.

What made Du Fan breathe a sigh of relief was that the Deputy Alliance Master Xiao of the Seven Star Business Alliance didn't seem to mean to embarrass him, and it was only when he teleported to the Seven Star Alliance in Jinling City that he got the letterhead of the Deputy Alliance Master Xiao.

Judging from the tone on the letterhead, Deputy Alliance Leader Xiao's mood was quite calm, and he only said that after March, someone would be sent to accept the progress of scientific research.

In this way, he no longer had any pressure, went to the Lingtang to take a shower, then returned to the living room, and went to bed.

Early the next morning, Du Fan was still asleep when he was woken up by the chatter of a group of disciples outside the door.

It turned out to be the twenty-nine core disciples of the Qixia Sect during the trip to the Valley of Hundred Flowers, and they were naturally overjoyed after learning that Du Fan and Chen Ru had returned safely.

These young men and girls had gone to see their senior sister Chen Ru as early as the day before, and it was late when they left, so they came to Du Fan to visit them early the next morning.

Seeing these disciples, Du Fan was very happy, the relationship between them was not ordinary, first the elders and disciples, then the instructors and students, after entering the Valley of Hundred Flowers, they were comrades-in-arms who shared life and death.

Du Fan chatted with them for a long time, and in the happy words of these disciples, Du Fan learned that they had all received a lot of rewards from the sect for their brilliant achievements in the Valley of Hundred Flowers.

A few of them are ready to try to build a foundation in half a year.

At the same time, Du Fan also got a piece of news, it was about Chen Ru, after meeting this woman, Qixia Ancestor gave an order to the sect, and recently arranged for Chen Ru to build a foundation, and under the discussion of a cadre of elders and the Maple Leaf Sect Master, the date was set ten days later.

Although Du Fan knew that building a foundation was not an easy task, in addition to factors such as mana purity, exercises, qualifications, auxiliary materials, etc., there was also the existence of the Destiny of Qi and Fortune, but in the case of Chen Ru, building a foundation should be no problem for her.

Under the strong request of these disciples, Du Fan simply told them about his experience with Chen Ru, and most of them were naturally omitted, but just these also made them fascinated and excited.

Du Fan very generously invited these disciples to drink a few cups of spiritual tea, and when they left, he also brought a lot of them with him, and now Du Fan's spiritual tea stock, but there is not much left, but he does not have the slightest sense of distress.

After these disciples left with a happy face, Du Fan looked at their backs and showed a thoughtful expression.

"For the monks of the Great Perfection of the Qi Refining Period, the best elixir should be the 'Gathering Spirit Pill', this elixir can only be taken when the cultivation has reached the Great Perfection of the Qi Refining Period, its medicinal power is very majestic, even for the monks of the foundation building period, there are many people who take it. ”

Du Fan nodded and continued to mutter: "When Miss Chen builds the foundation, this elixir should play a great role, I might as well prepare a few bottles of Gathering Spirit Essential Oil for her, although it may not be useful, but I should do my best." ”

For Chen Ru, Du Fan always felt that he owed something, how could he not know in his heart that he didn't have to worry about the matter of this woman's foundation building at all, not so much refining essential oils for this woman, but making himself feel at ease.

Either way, Du Fan has already made a decision.

He had a recipe for the elixir, which saved him a lot of research time, but he had never prepared this elixir essential oil, so he was not sure whether the quality of the ripening powder in his hand met his requirements.

However, even if he was able to use the current ripening powder to prepare this essential oil, its quality was not the best, because the several spiritual herbs that refined this elixir, but the higher the vintage, the better, even if he had high-grade spiritual herbs, he could not refine the juice essence.

After Du Fan pondered for a long time, he still planned to develop the first-grade ripening powder first.

Thinking of this, he didn't hesitate any longer, and quickly ran to the laboratory, using one of the sets of instruments, and started various experiments.

......

Two days later, the gray-faced Du Fan showed a happy look in the laboratory, at this time his image was a little sloppy, but his complexion was very good, and he could be described as energetic.

Du Fan was holding a vessel in his hand, and half of it was black powder, which was the batch of ripening powder he had just made.

These ripening powders have been tested countless times in this set of instruments, and they are the ones that can refine Breitling herbs...... First-level ripening powder!

"We still need to refine some more, and these may not be enough. ”

Du Fan exhaled lightly and started the refining of the next batch of first-level ripening powder, for him, since he had succeeded once, it would no longer be a problem to refine the first-level ripening powder in the future.

......

After most of the day, Du Fan refined a sufficient amount of ripening powder, and the technique was more skilled, and if he wanted to get it a few more times, he would not have to pay attention to it from time to time as he did now.

Under the flip of one hand, Du Fan took out a piece of bamboo slip, on which was the Danfang of the Gathering Spirit Pill.

"Dragon's beard orchid, spark grass, 100-year-old ginseng, 100-year-old Ganoderma lucidum, Zhuguo ......"

Du Fan had already understood these spiritual herbs, and after confirming them at this time, he put them away, left the attic, and walked to the medicine field.

A moment later, Du Fan returned to the laboratory again, and a large number of various spirit flowers and spirit grasses had already appeared in his hands.

Du Fan stopped the original use of the three sets of instruments, and immediately used the newly baked first-level ripening powder, and the three sets of instruments operated at the same time, and began to refine the juice essence of these spiritual herbs.

......

Three days later, several bottles of juice essence were placed in front of Du Fan, and without the slightest pause, he took out some samples from different juice essences, and then according to the proportion mentioned above by Danfang, he used these juice essences, as well as the first-level ripening powder that acted as a catalyst, and began the preparation of Juling essential oil.

After a stick of incense, Du Fan looked at the liquid churning violently in the vessel in his hand, his pupils suddenly shrank, and he threw it out of the window without hesitation.

After the "...... touch", an explosion suddenly sounded.

"Failed again, but it was much stronger than the last time...... Du Fan's face was a little ugly, this was his fifth preparation failure, but his eyes were bright, his fighting spirit was high, and he obviously had the momentum of becoming more and more courageous.

It wasn't until two hours later that he succeeded for the first time, holding a small transparent vial in his hand, which contained a small piece of yellowish liquid, which was the Gathering Spirit Essential Oil.

Du Fan exhaled lightly, and finally showed a smile on his face for the first time in recent days.

Next, he tried three more times in a row, and after all of them were successful, he began to prepare the batch of Gathering Spirit essential oil with a solemn expression.

A few hours passed like this, and at this moment, Du Fan was unkempt, his eyes were red, and his clothes were ragged, but his spirit was full of energy, and his face also showed a touch of joy that could not be concealed.

"Finally, before Miss Chen started to build the foundation, it was done. Du Fan took a deep breath, slowly exhaled it, put away the three vials full of spirit gathering essential oil in his hand, and left the attic.

When he walked to the gate of the other courtyard, Du Fan suddenly remembered something, frowned, and quickly rushed into the spiritual pond, and after a simple cleaning, he changed into a set of clothes, and then walked out of the gate of the other courtyard.

When he flicked his wrist and took out a speed talisman, he was stunned, and at this time, in front of him, a woman was standing, who was the person he was looking for.

"Elder Du, are you in a hurry?" Chen Ru looked at Du Fan with a smile and spoke softly.

Chen Ru was wearing a strange camouflage uniform, but a pink shirt, and her long hair naturally hung down to her waist, and after a breeze, her hair swayed.

The white snow fox was still holding in its arms, and the beast was leaning there quietly, not moving, just a pair of small eyes, looking Du Fan up and down, extremely cute.

At this moment, on Chen Ru's beautiful face, there was some curiosity, but also hidden expectation and nervousness.
