Gu Huan took out a jade bottle and a booklet without hurry, and told everyone.

It turned out that when he was an exile at the foot of the mountain in his early years, he was affected by disasters many times. Eating tree bark, grass roots, and even dirt, he ate almost anything to survive.

After going up the mountain to practice by chance, although he lived a life without shortage of food and clothing, the memory of the past was still deeply imprinted in his heart.

In addition, he accidentally got a few bottles of locust repellent powder from Guangling Sect, and then he began to study locust repellent powder whenever he had time. In order to find a cheap alternative, so that ordinary people under the mountain can also use it.

In this way, ordinary people will not have to fear the ordinary locust plague that occurs once every few years.

"The jade bottle contains the locust repellent powder of the Guangling Sect, and the booklet is the result of my research over the years."

"Summoning everyone here today is to gather the strength of everyone, not to seek to develop cheap alternatives, even if we can reproduce locust repellent powder, we can also take this opportunity to make a lot of money!"

After listening to this, although everyone admired Gu Huan very much, they didn't have much interest in the other party's proposal.

They only knew a little about some ordinary monks related to spiritual plants, and the other party had been studying them for so many years but couldn't do it. Now that the locust plague is coming, how can they study it themselves in such a short time.

On the contrary to the dejection of others, Lin Fan looked excited.

For him, with that booklet and a sample of locust repellent powder, if it were combined with the Epiphany Tower, it might not be impossible to study it!

Gu Huan also noticed Lin Fan's abnormality, and hurriedly asked, "Senior Brother Lin, do you want to give it a try?" ”

"I also like to study the art of spiritual planting, and now a great opportunity is right in front of me, if I don't give it a try, I won't be willing."

When Gu Huan heard this, a smile suddenly appeared on his face, and he handed over the jade bottle and the booklet.

"Senior Brother Gu, don't you use these things?"

"It's okay, I still have a backup, you can just take it."

After another round of cup pushing and changing, the party also came to an end, and Lin Fan and the others retired one after another.

……

Ever since Lin Fan had an epiphany about the Spirit Plant, he was already equivalent to a master-level existence in terms of Spirit Plant.

Therefore, it only took half a day for him to study Gu Huan's booklet thoroughly.

After spending another half a day studying the locust repellent powder in the jade bottle, he understood how far Gu Huan had studied.

Gu Huan's research direction was right, and he excavated ten kinds of spiritual materials for the locust repellent powder formula, and only the last two spiritual materials were left and I don't know what they were.

However, studying the formula is not so simple, even if you know all the spiritual materials in the formula, you still have to study the ratio of each spiritual material, as well as the specific preparation method.

In his opinion, Gu Huan's move to invite them to crack the formula of locust repellent powder was simply casual, and he probably didn't have much hope.

After adjusting his body and mind to the best state, his spirit entered the Epiphany Tower with ease.

As he entered that wonderful state of epiphany, the formula for repelling locust powder no longer had any secrets in his eyes, and even the specific spiritual material ratio was quickly deduced by him.

Then, he drew inferences from each other, and quickly researched some of the substitutes for the spiritual materials, and even the number of spiritual materials required was reduced from twelve to six by him.

And these six kinds are all common spiritual materials in the world, and their cost is only one percent of the locust repellent powder of Guangling Sect!

He then left the Tower of Epiphany satisfied.

After thinking about it for a long time, he finally decided to make a slightly weakened version of the Guangling Sect's locust repellent powder.

There was no other reason, but he didn't want to cause trouble. Although this locust repellent powder is not a precious item, if the finished product of one's own research is better than the other party's, it is too eye-catching.

In the past few days of his research, dozens of imitations of locust repellent powder have emerged all over Yunzhou. There is not much more than him, and it will not attract the attention of others.

Although there is a locust plague in Yunzhou every few years, it is basically a small-scale locust plague, which affects ordinary people at most.

A locust plague like this one, which is large enough to affect the spiritual world, is a once-in-a-thousand occurrence.

Therefore, the sale of imitation locust repellent powder is a hammer sale, and after some time the locust plague has passed, the formula is given away for free, and no one is rare.

As for the formula that is low enough to be generalized to the mundane world and benefit the people, he hides it deep in his heart.

Without him, before he has enough strength to protect himself, he will come up with this recipe and find death.

After determining the goal, Lin Fan immediately began to purchase spiritual materials in the door and developed a weakened version of locust repellent powder.

……

A few days later, Lin Fan brought the locust repellent powder he made and went to visit Gu Huan.

The reason why it took so long was because his body was not familiar with the operation process. As a result, when preparing locust repellent powder, it took a lot of time to win.

Although he made it, half of it was due to the research records and finished locust repellent powder provided by the other party.

Without the finished product, his research would have no reference, and it would be much more difficult. Without that note, it would take more time to have an epiphany.

Senior Brother Gu Huan has a reliable character, and he is also relieved to cooperate with him.

And he was deeply corrupted by fire poison, and he was strong in his previous development, and he had no ability to produce a large amount of locust repellent powder in a short period of time.

Moreover, he only has a few spirit stones left on his body now, and he has no capital to buy a large number of spiritual materials needed to repel locust powder.

The most important thing is that in this selfish immortal cultivation world, Senior Brother Gu's dedication can be described as extremely precious.

Lin Fan asked himself if he could do it, all he could do was to give a piece of the locust repellent powder to the other party.

This is what Senior Brother Gu deserves.

……

Inside the gazebo.

Gu Huan looked at the locust repellent powder made by Lin Fan, his face full of disbelief.

Just now, he also tested it with the locusts brought back by Jia Pei, and it turned out that the locust repellent powder made by Lin Fan was really effective!

"Senior Brother Gu, this is the specific recipe for imitating locust repellent powder." Lin Fan said and handed over a page full of words.

"Senior Brother Lin, this is unacceptable, this is the result of your hard research, how can I accept it?" Gu Huan pushed the paper back with a serious face.

"If I hadn't stood on Senior Brother Gu's shoulders, how would I have been able to study this locust repellent powder?"

"Besides, what kind of research is I, but I just found a few kinds of spiritual materials and tried them out. It's just a matter of God's appreciation and good luck. ”

"This ......," Gu Huan was speechless for a while.

"Senior brother, don't excuse me, no matter what you say, this formula can be regarded as your research, and I can only be regarded as an auxiliary person."

"Don't hide it from Senior Brother Gu, now I still have fire poison left in my body, even if I want to make locust repellent powder in large quantities, I still have the strength of my heart and lack of energy."

"In this case, you accept this recipe and claim that you researched it. The locust repellent powder you make through this recipe will give me fifty percent of the profits. ”

After some hard work, Gu Huan finally agreed to Lin Fan's proposal.

In addition, he also gave Lin Fan a copy of the body refining technique "Qingyang Forging Technique".

This classic was obtained by Gu Huan by accident, and he didn't like to practice physical arts, so he only ate ashes in his hands.

He had also heard about Lin Fan's reliance on the Spirit Tortoise Fist to break through the trial tower that day, and the other party obviously needed this kind of body refining technique more than himself.

In the battle with the Fire Pattern Rock Turtle, Lin Fan deeply realized the shortcomings of his physical body. If the physical body can go further, why break the bones of the hand?

Furthermore, the Spirit Turtle Fist is a method of using strength. If his own strength becomes stronger, then the power that the Spirit Tortoise Fist can exert will be further amplified.

Therefore, he naturally accepted this classic happily.

After that, Gu Huan hurriedly purchased a large number of spiritual materials needed for the formula, and made locust repellent powder day and night.

Those beginner disciples were already anxious like ants on a hot kang, and they couldn't buy locust repellent powder at all.

Now seeing that Gu Huan has imitations for sale there, and the quality is also guaranteed to a certain extent, he immediately came to the door to buy.
