When Zhou Chun learned about Han Yuan of Qianlingmen from Zhou Mingde's mouth, he was also full of surprise.

He couldn't have imagined that the owner of the underground mausoleum was likely to be the creator of this insect plague.

A Jindan monk created a huge insect plague that affected several countries, and I am afraid that this matter will cause a big storm when it spreads.

And when he read Han Yuan's research notes and the insecticidal prescriptions he left, he quickly understood what Zhou Mingde meant by coming over to him.

I saw him look directly at Zhou Mingde and ask, "Is Elder Taishang worried that it will be difficult to explain the origin of these prescriptions after directly providing these prescriptions?" ”

"Yes, if this prescription is really effective, and we offer it again, it will definitely attract inquiries from those senior monks."

"And if it is truthful, the old man is worried that these insect repellent techniques left by Han Yuan will be confiscated, and our Zhou family will be strictly forbidden to cultivate!"

"In that case, the harvest of this exploration of the underground mausoleum will be greatly reduced!"

Zhou Mingde nodded slightly, and expressed his worries in a low tone.

His concerns were rightly founded.

Since he knew that this insect plague was probably artificially created by Han Yuan, then these insect repellent techniques left by Han Yuan, as well as those Thousand Spirit Gate forbidden techniques that made Zhou Mingde quite greedy, would definitely be confiscated by those Yuan Infant Stage cultivators and not allowed to spread any further.

If you meet that ruthless Yuan Infant Monk, it is not surprising that Zhou Mingde and Zhou Chun will be killed.

In this case, it is definitely not possible to just tell the truth.

Therefore, after Zhou Chun listened to Zhou Mingde's words, he also nodded in agreement and said: "What Elder Taishang said makes sense, it will definitely not work according to the truth, we can't take that risk!" ”

After thinking about it for a while, he made a suggestion: "The younger generation thinks that the most reliable way is to test the authenticity of the prescription first, if it is true and effective, let's find a way to add a few ingredients to reduce the efficacy of the medicine, and then offer the new prescription!" ”

"Those senior monks are all people with extraordinary knowledge, there must be masters who are proficient in pharmacy, after the formula we changed is in their hands, as long as they try it a few more times, most of them will be able to restore the original powerful formula."

Now that the insect plague is raging, countless monks are researching ways to completely eradicate the insect plague.

An effective anti-insect prescription, even if its effect is not particularly strong, will definitely attract attention, so that some high-level monk needles can perfect and study it.

In this way, with the correct research direction, with the ability of those high-level cultivators, it will indeed not be difficult to restore the formula before the Zhou family's changes.

In this way, no one would have thought that the Zhou family would deliberately make the formula complicated.

It's just that if this is really done, the credit of the Zhou family will definitely not be as great as directly offering the original formula.

Therefore, after listening to Zhou Chun's suggestion, Zhou Mingde did not make a decision immediately, but lowered his head and pondered.

He needs to weigh the trade-offs.

After pondering like this for a long time, he finally nodded and said, "Zhengchun, your suggestion is good, our Zhou family's harvest this time is big enough, and it is indeed not suitable to be so eye-catching!" ”

After discussing this, the two began to collect relevant materials and make the poison on the formula.

Because they have a detailed recipe, even without borrowing the hands of others, the two of them can refine poison according to the recipe.

Seven days later, the first poison against the bloodline characteristics of the "Thousand Variations" was successfully configured, and then it was tested with the demon insects it caught.

The results of this experiment made Zhou Mingde and Zhou Chun mixed.

Happily, the poison does have a good effect, much better than the poisons researched by Zhou Jiawei.

Worryingly, the effect was not as strong as the two expected.

Later, they also configured the poison against the bloodline characteristics of the "Spirit Devouring Ant".

Compared to the poison against the "Thousand Variations", this poison is somewhat special and requires the use of a different medium.

Zhou Chun: They need to first let a beast or demon beast swallow the poison and kill it, and then let the demon worm devour the corpse of the dead beast or demon beast.

According to Han Yuan's record on the formula, as long as the "Spirit Devouring Ants" devoured the corpses of dead beasts or demon beasts, they would slowly die within a day, while the other "Spirit Devouring Ants" that devoured their corpses would also be poisoned.

However, when experimenting with demon insects, demon insects developed a strong resistance to this poison.

The demon insect that devoured the poisonous flesh and blood also experienced various discomforts for a while, and it seemed very sluggish, but it would gradually recover after a day.

Obviously, these demon insects that are now ravaging the Yang Kingdom have made up for some bloodline defects in the process of evolution, making the poison that is aimed at the characteristics of their bloodline no longer work so well.

In this way, Zhou Mingde and Zhou Chun were a little difficult.

The effect of the original recipe is so unsatisfactory, if they still follow the plan and add enough materials to reduce the efficacy of the medicine, they are afraid that the poison may not even be able to poison the demon insects.

In that case, how can you get credit by donating medicine?

"For today's plan, there are only two ways, one is to ask Uncle Fourteen to conduct in-depth research on the previous prescription to see if he can develop a new prescription that is more effective for demon insects, and the other is to directly present the original prescription, which is said to be a prescription for the Thousand Varieties originally included in the family, and it was found to be effective after actual experiments!"

In the quiet room, Zhou Chun rubbed his forehead, frowned slightly and said his new opinion.

But in his heart, he actually prefers the second way he said.

The reason is also very simple, the sooner the insect plague is eliminated, the loss of the human race will be reduced.

And the first way is not to say whether it can be done, and even if it can be done, it is estimated that it will not be successful in ten days and a half months.

However, he knew that he was now a staff officer for Zhou Mingde, and the purpose of a staff officer was to make relevant suggestions.

As for which method should be used, it should be up to Zhou Mingde to make the decision.

So even if he is biased in his heart, Zhou Chun will not deliberately only say the method he prefers.

This is also what Zhou Mingde and Zhou Daoyi like about him.

When it comes to the interests of the family, he can always make rational analysis, put forward useful suggestions, and often put forward suggestions that make people feel novel.

At this time, after listening to Zhou Chun's two suggestions, Zhou Mingde just groaned slightly, then shook his head slightly and said: "Researching new prescriptions by yourself is too time-consuming and full of too many uncertainties, and it is really not the best policy." ”

"However, it is not appropriate to say that the prescription is inherited by the family, and it is difficult to withstand the investigation, especially the investigation of Qinglian Temple!"

Speaking of this, he took another deep breath, and then sighed long: "It seems that the existence of the underground mausoleum can only be exposed!" ”

The recipe for the poison was obtained from the underground mausoleum, which is not something that cannot be explained at all.

The only thing that needed to be concealed was the fact that the tomb owner, Han Yuan, had cultivated a demon insect through the forbidden technique experiment.

Those Han Yuan's research notes, as well as the forbidden art inheritance of the Thousand Spirit Sect, must not be leaked out!

Fortunately, the relics left by Han Yuan all fell into the hands of Zhou Mingde.

Even Ruan Hongxiang, who was lucky enough to escape that day, didn't know who the tomb owner was and where he came from.

I only know that the owner of the tomb is a Jindan monk who is good at repelling insects.

In this way, if you only throw something that can see the light, you should be able to get through.

After listening to Zhou Mingde's words, Zhou Chun also instantly understood what he meant, and immediately said out loud: "If you follow the method of Elder Taishang, then we have to check the classics that are going to be exposed, but don't let people find out that we have something to hide from these classics!" ”

"Yes, check it out!"

Zhou Mingde nodded thoughtfully, and then took out all the harvested classics and thoroughly investigated them with Zhou Chun.

In this way, after three days and three nights of sleepless thorough investigation by the two, all the classics that could be exposed were finally screened out.

Most of these classics that can be exposed are some illustrated classics that record the appearance, ability, and habits of demon insects, as well as some cultivation methods for insect repellent techniques, and of course, some prescriptions for insect extermination and insect repellent.

The texts about the core secret techniques and forbidden techniques of the Thousand Spirits Gate were all stored in a separate storage bag, and they would be temporarily buried somewhere in the wilderness at that time.

"Okay, we've double-checked it three times, and there should be no problem."

In the quiet room, after Zhou Mingde reviewed the classics that could be screened out for the third time, he finally nodded with complete relief, making sure that there was no problem.

The stakes are too high for him to be careless.

If this thing really goes wrong, not only will their contribution to the medicine be completely wiped out, but it is very likely that they will be killed!

"Since there is no problem, when do you plan to leave, Elder Taishang? How do you plan to do this? ”

Zhou Chun looked at the pile of classics in front of him, but asked about the follow-up.

Hearing his words, Zhou Mingde only groaned slightly, and then quickly replied: "The old man will rest for a day to recuperate, and then go to Rongguo to meet the Shanyangzi seniors of Qinglian Temple, and report the matter to him." ”

Speaking of this, as if he had thought of something again, he suddenly said to Zhou Chun: "Just in case, make a copy of these classics and put them on Zhengchun you, and the two magic weapons will also be taken by you first, and then you will go to other places alone to hide." ”

"If the old man successfully meets the real person of Yuanying, he will naturally come back to you, if you don't see the old man come back, return to the family immediately, inform Dao Yi of everything, and then arrange for the clan to take refuge in the wilderness!"

His arrangement was obviously worried that Shanyozi's side would kill him in order to monopolize the credit.

Although this is not very likely.

Zhou Chun didn't say anything when he heard what he said, just nodded emphatically and said, "Juniors understand." ”

Then Zhou Mingde went to rest by himself, and Zhou Chun rubbed and copied those classics alone.

In the evening of the next day, Zhou Mingde, who had rested for a day, took those classics and went to Rongguo.

And after Zhou Chun explained to Zhou Jiapeng and a few others, he also left Fang City and looked for a barren mountain and mountain to live in seclusion.

Not to mention how Zhou Chun lived in seclusion in the barren mountains and mountains, and said that after Zhou Mingde left the Fang City of the Great Cloud Kingdom, he galloped all the way towards Rongguo.

It took less than a day for others to arrive in Rongguo.

At this time, in the territory of Rongguo, there were raging demon insects everywhere, and immortal cultivators who cleared out demon insects could also be seen everywhere.

Zhou Mingde also inquired in many ways before he found out the location of Qinglianguan and his party.

According to the information he found, he arrived outside the mountain gate of a cultivator family in Rongguo, and it is said that Qinglianguan and his party are now using this as a station to carry out the operation of clearing demon insects.

It's just that after he entered the mountain gate of this family, he couldn't see Shanyozi for the first time, because the other party also went out to clean up the demon insects.

Fortunately, Zhou Mingde's area under the rule of Qinglian Guan can be regarded as famous, and the monks of Qinglian Guan Zifu who stayed in the garrison learned that he had something important to report, and specially arranged for him to contact Shanyangzi.

After waiting in the station for most of the day, Zhou Mingde waited for Shanyangzi to return.

"Zhou Daoyou came here to meet the old man in a hurry, I don't know what is important?"

In the quiet room, Shan Yangzi, who was wearing a yellow robe, sat cross-legged on the collapse, looking at Zhou Mingde with a calm face and asking what he meant.

As a monk sent by Qingyangguan to preside over the "Hundred Tribes Conference", Shanyangzi still has some impressions of Zhou Mingde, after all, Zhou Mingde was also in the limelight at that event.

And before leaving, the Guan Lord Qing Weizi also explained to him the purpose of letting the Zhou family come to Yangguo.

These are the reasons why he rushed back to see Zhou Mingde after hearing that he had come to see him.

So when he asked Zhou Mingde about his intentions, he seemed to have a calm face, but he also had some expectations in his heart.

Regarding the horror of this insect plague, Shanyangzi, who participated in the war to intercept the migration of insect swarms, is much clearer than Zhou Mingde and Zhou Chun.

He also knew better that the upper echelons of the human race were now eager to eradicate the insect plague.

It's just that even with a hint of expectation, Shanyangzi actually didn't dare to believe in his heart that this Purple Mansion Stage monk in front of him really had a way to eliminate the insect plague.

After all, so many Yuan Infant Stage monks who have cultivated to a high level of strength can't do this, and so many erudite Jindan Stage monks haven't thought of a way yet, how can they have too high expectations for a Purple Mansion Stage monk!

However, what Shanyozi didn't expect was that in the face of his inquiry, Zhou Mingde was also very direct and immediately replied: "If you go back to your seniors, the juniors have come to Rongguo to meet your seniors this time, precisely because they have found a way to restrain demon insects!" ”

"What? What did you say? ”

Shanyangzi was stunned for a moment, then looked at Zhou Mingde with wide eyes with a big change in his face, and said hurriedly: "You make it clear, whether you have found a way to restrain demon insects, or have you found a key way to eliminate the insect plague!" ”

】

Shanyoko hoped that Zhou Mingde was talking about the latter, but she couldn't believe that it would be the latter.

Because of the method of restraining demon insects, as immortal cultivators continue to exterminate demon insects, many effective restraint methods have been discovered.

But the key way to eradicate the insect plague has not yet been found!

Zhou Mingde naturally understood the meaning of Shanyangzi's words, and quickly said in an affirmative tone: "It is the key method to eliminate the insect plague, the junior has found a poison formula that has a great effect on demon insects, and determined that this poison can be made on a large scale to kill insect swarms on a large scale!" ”

Can be mass-produced, mass-killing swarms!

Hearing Zhou Mingde's affirmative tone, Shanyangzi could no longer restrain the excitement in his heart, and instantly stood up from the collapse and rushed to Zhou Mingde.
