After a while, Song Atom returned again, at this time he was full of smiles, in his hand, there was already an extra storage bag, and he came to Du Fan in a few big strides and handed it over to the other party.

Du Fan took it over and carefully inspected it, and found that there was a jade bottle the size of two fingers in the storage bag, and there were no more than one hundred sea silks.

& is thirty-two mid-level spirit stones. Du Fan flicked his wrist and also threw a storage bag to the old man.

After a brief investigation, Song Atom immediately made up his mind, and said with a smile: "It is really a blessing in life to cooperate with a refreshing person like Du Daoyou, the old man still has a few spiritual fruits here, if Daoyou has time, you can taste one or two and then go again." ”

& Xie Songyuan is friendly, but I'm going to go back in a hurry, next time. Du Fan touched the storage bag seemingly casually, and said pointedly.

Song Atom's eyes froze, and he determined a few points again for his previous guess, and at this moment he smiled even better, and said attentively: "In this case, the old man personally sent Du Daoyou out, Daoyou please." ”

......

After walking out of the shop in Songatom, Du Fan did not linger any longer, and decisively left this fang city, and the speed was fully launched, heading straight for the previous village.

A few hours later, Du Fan left the village, and after making a big circle, he appeared at the place agreed with Zhao Chong and the others.

& Brother waited for a long time, and when he first came to Fang City, he visited many shops under curiosity, so that he was delayed for a lot of time and didn't know it, which is really ashamed. After approaching Zhao Chong and the others, Du Fan arched his hand, his expression showed a hint of embarrassment, and said apologetically.

& Brother doesn't have to be like this, it's not easy for me to wait for a Fang Market, and it's normal to spend more time, and besides, we just came out and didn't wait too long. Yuan Li waved his hand and said with a smile.

Du Fan smiled at Yuan Li and the others, and said no more.

Next, they unfolded their movements and galloped back in the direction of Langlin Valley.

The journey went smoothly, and on the fourth day, Du Fan and the others returned to the valley, and the three of them only talked for a while, and then dispersed.

After Du Fan returned to his wooden house, he sat cross-legged, holding a small bottle full of ginseng qi essential oil in his left hand, and dragging the Hua Dan water that he had bought with a large amount of spirit stones a few days ago, and he was hesitating between the two, as if it was difficult to choose.

& Repair for improvement, or study the composition of the Dan water......"

But the next moment, his eyes lit up, and he suddenly thought of something that didn't have much to do with either.

& However, Hua Dan water can dissolve the impurities in the demon pill, then this thing must be restrained by demon beasts, that is to say, even if it is a living demon beast, it should not like such a thing as Hua Dan water.

However, what the monster doesn't like is the most likely ...... It's the main ingredient of Hua Dan water!"

Du Fan's eyes became brighter and brighter, as if he had caught something, and his breathing became short.

& In this way, as long as the main material of Huadan water is found, and then some experimental methods are used, you can find out what is compatible with this main material.

This kind of thing is very likely to be something that the monsters like, if that's the case, you can smear this thing on the fishing net to attract the monsters, and the effect will definitely be much stronger than fish food. ”

Du Fan's mind was in a hurry, and he kept calculating, and finally came up with a theoretical result that made his heart pound.

Although it is only a theoretical possibility, and the whole set of experiments is quite complicated, I have a hunch that this can be done!" Du Fan took a deep breath, closed his eyes, and when he opened them again, he had already made a decision.

& Here, although it is impossible to go to a large number of ripening spirit herbs, but if you do some scientific research, if you are careful, you can barely do it.

There are a lot of spiritual herbs that I carry with me, both in type and quantity, and if I am lucky, the composition materials of the Hua Dan Water, as well as the kind of restraint I deduce, may be found in the Qiankun Ring. ”

Thinking of this, Du Fan no longer hesitated, and immediately got up to cover the doors and windows of the room, and at the same time urged the light curtain unfolded by the forbidden magic tool to the extreme, then took out a set of experimental equipment, poured Hua Dan water into one of the vessels, and began to study the composition of this potion.

After a few hours, Du Fan discovered that studying potions in liquid form was more complicated than solid elixirs, but for him, the difference in difficulty was completely negligible.

Two days later, Du Fan finally completed the first step, he had already decomposed the components of Hua Dan Water, and their current form was a colorful crystal particle.

Next, Du Fan began to examine the crystal particles one by one, and after another day, he analyzed the source of these crystal particles.

It turned out that the main ingredient of Hua Dan Water was a spiritual liquid called Sanqing Shui, which Du Fan had heard of and was considered a rather high-level auxiliary material.

Sanqingshui is on the Kyushu continent, although it is famous, but it is an extremely rare thing, so Du Fan has not come into contact with it.

At this time, under the research, Du Fan knew that Sanqing Water was not a primitive thing, and this spiritual liquid was also refined, and its ingredients included peacock grass, bellflower, dust grass, mountain spring water and other spiritual materials.

However, in addition to the main material of Sanqing Shui, Huadan Water also has more than ten kinds of secondary spiritual herbs such as Fusang leaves, mirror flowers, and Tianlin grass.

& I thought that the ingredients of a mere bottle of Hua Dan water were so complicated...... Forget it, anyway, it's not like to start preparing Hua Dan water now, as long as you find its main raw materials. ”

Du Fan sighed, then grasped the key point and continued to study.

After a few hours, under his experiments, he was able to determine that among the materials of Sanqing Shui, the proportion of peacock grass was the largest, so the spirit herb that had a restraint effect on demon beasts, Bacheng was Peacock Grass.

& The most important thing is to find the spiritual herbs that are compatible with the peacock grass!"

Du Fan's eyes flashed, he no longer hesitated, and began to get busy again.

A day later, Du Fan was a little tired, but his expression was very excited, he finally found something that was compatible with peacock grass, and this spiritual herb happened to be what he already had, "cat's eye grass"!

This kind of cat's eye grass, whether it is attribute or medicinal properties, is compatible with peacock grass, then, this spirit grass is most likely the favorite of demon beasts, of course, this is only a theoretical assumption, even Du Fan, there is no ten percent certainty.

Du Fan prepared some spirit herbs similar to the type of cat's eye grass and kept them for backup, if the cat's eye grass didn't work at that time, he could only try these spare spirit herbs, but for his own calculations, Du Fan still had six or seven points of certainty in asking himself.

The next problem comes, the cat's eye grass on Du Fan's body is too few, only a few plants, if it is scattered into a few tens of bait, it will definitely not be enough.

However, in his Qiankun ring, there are still a lot of cat's eye seeds, he hesitated for a while, and finally decided to plant some, and then apply special fertilizer to ripen it.

In this way, even if the cat's eye grass only grows for one day, it will have more than three months of medicinal properties, although the alchemy is insufficient, but it is more than enough to use it as bait.

Du Fan paced back and forth, looked around the room, and finally landed his gaze under the wooden bed.

Next, Du Fan carefully planted a row of cat's eye grass at the bottom of the wooden bed, and applied some special fertilizers, and after doing this, he sat back on the wooden bed cross-legged and began to refine the ginseng qi essential oil.

Two days passed in a blink of an eye, Du Fan opened his eyes, calculated a little in his heart, and hurriedly got out of bed to collect all the medicinal cat's eye grass for more than six months, and cleaned up the traces on the ground.

& It's time to go to sea and do the mission. Du Fan sighed, his eyes were deep in an instant, and he couldn't tell whether he was happy or worried.

Du Fan didn't need Zhao Chong and the others to come looking for him this time, but took the initiative to leave the wooden house and went straight to a square where he had received the task in the past.

After arriving there, Du Fan only waited for a moment, and then saw Zhao Chong and Yuan Li striding from a distance.

& Brother Zhao came early, Brother Zhao and I just went to the wooden house where you were, and found that Brother Du was not there, so we guessed that you might have come here in advance. After approaching, Yuan Li said in surprise.

& In the past, I delayed everyone's time because of me, and I was really uneasy in my heart, so I came over a little earlier this time. Du Fan smiled slightly and said politely.

It's only been a few days, and Brother Du's cultivation has improved a lot, which is really gratifying. Zhao Chong's expression moved, and he looked Du Fan up and down, looking a little surprised.

& This point of cultivation is not worth mentioning, but Brother Zhao, you are only one step away from the Great Perfection of the Qi Refining Period. Du Fan smiled noncommittally, and then said quietly.

> Hey, Brother Du has good eyesight, Brother Zhao's cultivation was originally at the peak stage of the seventh layer of the Qi Refining Period, and in the Fang Market half a month ago, he purchased a few more Ginseng Qi Pills, and after refining, his current cultivation has faintly touched the threshold of the Great Perfection.

I believe that it won't be long before Brother Zhao can truly enter the realm of the Great Perfection of the Qi Refining Period, and in a few years, after Brother Zhao breaks through to the foundation building period, our good days will come. ”

Before Zhao Chong could speak, Yuan Li on the side interjected with a smile, and his expression couldn't help but dance.

Du Fan was stunned for a moment when he heard this, and then smiled, but he didn't say anything.

& Brother, don't make fun of me, for me, there is still a chance for the Great Perfection of the Qi Refining Period, and as for building the foundation, it is something that I don't need to think about at all. Zhao Chong shook his head and smiled bitterly.
