Du Kang thought about it, even if this Li Tongju did have money, he was still an ordinary person in essence. Changing souls with an ordinary person means not only taking the risk of "having no power to resist after being discovered" and "the soul does not match the body", not to mention the limited lifespan, it must be extremely difficult to recultivate and cultivate, if you are not desperate, who would choose such a method?

"In this kind of peaceful and prosperous world, demon cultivation really belongs to the category of cornered...... But what if it's troubled times? Du Kang fell into deep thought.

At that time, how rampant will the demon path and demon cultivation be?

"Although there are still some petty thefts and occasional extreme incidents in modern times, it is certainly the best peaceful and prosperous era compared to before." Du Kang thought to himself, "The most important thing is that there is enough food so that people will not starve to death.

'The people live on food', this is not just a rhetoric...... However, as the process of aura recovery continues, the imbalance brought about by the power system, the impact of behaviors such as 'armed with sharp weapons, murderous intentions', and the distribution of classes, interests, and cultivation resources will definitely lead to the emergence of various problems......

The decision I made was right, to keep only the seeds with a meager spiritual power that could promote cultivation, but the yield was enough to benefit the whole people, and fundamentally reduce the possibility of conflict......

Tsk, I feel like a heavy responsibility, let's put more effort into the formation to ensure that there will be no problems with the seeds...... But what if something goes wrong? ”

Du Kang suddenly suffered a little bit from gains and losses, hundreds of years, although in modern times, when he went to Mao'er Mountain, he checked that the formation was still there, and it remained intact, but he did not enter the interior to check...... What if something goes wrong inside?

There is no such thing as an impossible thing, it is just a matter of the magnitude of the probability, and as time goes on, the more unknown factors, the probability of the unexpected will naturally increase.

"I still have to think of a way, and do a little more insurance measures...... Du Kang began to think of a way.

"Either it is stored in batches and in multiple locations to reduce the loss caused by accidents, which is equivalent to not being able to put eggs in one basket...... Well, it's a way, and then think about whether there are any other ones? ”

"What are you thinking?" Xiao Xuan's voice brought Du Kang back to his senses from his contemplation.

"Oh, I'm thinking about a question...... Du Kang thought about it and decided to ask Xiao Xuan's opinion.

"If I'm going to save something, it can be divided into many parts, but it needs to be seen much later, and in the process, if there is any chance that it will be damaged, what can I do to minimize the possible loss?"

"Oh...... Sounds like when I hid fish and meat. Xiao Xuan thought for a while and said.

"I used to catch fish in the river, and sometimes I caught too much and didn't want to put them back, so I liked to find a place to hide them. Buried in the soil, hidden in a tree hole or somewhere else, but buried in the soil will be cut off, and what is hidden in the tree hole will rot, and the rest of the place is not very safe...... In the end, I found that it was the safest in my stomach. ”

Du Kang nodded. It is impossible to hide it in the stomach, as for the method of storing it in different places, he had already thought of it for the first time before, but there is still a problem in the implementation - if the formation with Yunxiao, Shi Yuye, and Ji Shen to help cannot be saved, then what other suitable position is there?

At least you have to find a location with almost the same security to be able to preserve, and you can't really bet on that hand "intentionally planting flowers and flowers, unintentionally planting willows and willows", which is unreasonable.

But at least it shows that these two things have something in common in nature, and it depends on what inspiration Xiao Xuan's words can inspire him.

Seeing that Du Kang was listening carefully, Xiao Xuan became more and more energetic the more he spoke. Probably for cats, hiding fish or meat is similar to human saving money, and being able to save money while eating and drinking is a particularly difficult skill.

"Later, I tried different methods, such as hiding the fish in the water, or learning how to salt it and then hide it...... Anyway, I tried all kinds of methods, and then I looked at it again after a while, and found that the best hidden thing was indeed ......"

"Wait...... Try all sorts of methods and then look at them after a while? Du Kang raised his hand to interrupt.

"Yes," Xiao Xuan tilted his head, and the cat was puzzled, "Of course, you have to try it all to know which one is good." ”

"It really should be." Du Kang nodded, had an idea in his heart, and immediately took out the clairvoyant mirror and entered spiritual power.

At this distance, Du Kang could directly use the spiritual power incarnation to go back, but with the idea of giving things a try when he got something, Du Kang chose to use the clairvoyant mirror.

In just a moment, as soon as the clairvoyant mirror lit up, the faces of Yunxiao and Shi Yuye appeared in the mirror, and it seemed that the two were still together.

"What trouble is Du Gongzi running into?" Yunxiao asked. The agreed time was at night, and Du Kang used it in advance, which inevitably made her think about it.

"Is there going to be a fight? Is there another fight? Shi Yuye asked expectantly.

The corners of Du Kang's mouth twitched, why are you sending a child so much to fight?!

Is it really so rewarding to get an enemy pregnant?

Wait, if you think about it carefully, it does seem to make sense, after all, it is a means of combining physical and mental attacks...... Du Kang felt that if he had a chance in the future, he could ask Shi Yuye to borrow some water from the Zimu River to play, of course, that would be later.

"No, it's just a little thing...... I have already informed Guicheng Chenghuang to come back and deal with it. The reason why I contacted in advance was because I suddenly thought of one thing, because the seeds I asked for were very important, so I thought about adding some insurance means to avoid too big problems. Du Kang said, "About the formation...... Is it possible to adopt a segmented design layout? ”

"Segmented design layout?" Yunxiao was stunned for a moment, thought for a while, and then asked, "Does Du Gongzi mean the son-mother array?" ”

"That's pretty much what it means, in order to ensure that the storage of seeds is preserved as much as possible, I think it's a good choice to divide different small formations into different small formations within a large formation to create different spatial environments." Du Kang nodded.

"For example, one part is preserved according to the preservation method of the god Ji, and the other part is planted directly with those crops......"

This is what Du Kang thought of, but in fact, he also concealed one step of operation and did not say it, that is, such a segmented preservation formation, he can verify it by returning to the modern era, without worrying about failing all of them once, because he only knows a small part of the results, and the other parts can not open the formation, so they will naturally not be affected, and they can be operated at will!

Because only a small area is used for testing at a time, the number of tests that can be provided is very large, and it is a big deal to change the location of a mountain when all the testing space is used up...... Du Kang felt that the problem should not be big.

In fact, there is another purpose, which is to solve the matter quickly.

Originally, Du Kang was going to do a lot of things in ancient times at once this time and then return to modern times, but now, after thinking of this incident because of this incident, he was a little relieved...... I have been thinking about an important thing in my heart, and I don't have a good time traveling, so it's better to get it done as soon as possible.

"What Du Gongzi said is reasonable." Yunxiao thought for a while, "In fact, I have already designed the overall defensive formation of the cave, and Ji Shen also left a preservation method before, with the efficiency of Du Gongzi, you learn to make the array plate, and estimate the time of an hour, you can already do this part well, and directly separate a piece of area to complete the formation first, and it will not affect the subsequent layout arrangement of other areas." ”

"Really? That's exactly what I mean! Du Kang's eyes lit up.

Calculate the time, complete the formation, and Guicheng Chenghuang will almost come back, and at that time, he will directly deal with the things at these two ends, and take advantage of the fact that he has not left far, return to the modern era, and check the results of seed preservation.

If it is well preserved and can survive normally, then the matter of the seeds will be dealt with; If it is not well preserved, it will be corrupted, so go back to ancient times and try another way...... Of course, Du Kang believed in the guarantee of the god of Ji and the means of the clouds, so he was more inclined to solve the matter at one time in his heart, rather than use it to go back and forth.

In this way, the change of the plan was directly determined, Du Kang was not ambiguous, and directly left a spiritual power incarnation here, and then the main body took Xiao Xuan to Guicheng, that is, two or three minutes of work, returned to Guicheng Zhaoyao Mountain, and began to make a formation plate.

Although the incarnation of spiritual power is convenient, the overall ability to control and mobilize spiritual power is definitely not as good as the body, Du Kang wants to make the most perfect and best formation in the best state, so as to improve the success rate of preservation.

Li Tongju's side is not in a hurry at all. Originally, Du Kang still wanted to take down this demon dao directly, but after discovering that the demon dao's body was running out, and Li Tong's body was almost destroyed, he changed his mind - let the two of them change, looking forward to what kind of expression the two of them would have after they changed!

Not long after Du Kang's body began to make the array plate, Guicheng Chenghuang arrived in Guibei County, saw the spiritual power incarnation left by Du Kang, and began to deal with it after a brief understanding of the matter, as well as ...... Write reports.

Although when he first received the news, it was a free and easy sentence of "continue to play music, then dance", but when such a thing happened under his rule, it was not appropriate for him not to rush back to deal with it.

In fact, Du Kang really did him a great favor, because Du Kang handled this matter as the city god of Guicheng throughout the whole process.

As we all know, if this kind of subordinate is found out by other outsiders, Shangguan generally cannot escape joint and several responsibility, but if Shangguan finds out by himself, it is different...... Guicheng Chenghuang is not afraid of making mistakes and being punished and demoted, he is afraid that he will increase the amount of tasks on him, and then he will not even have the free time to find a substitute.

Everyone is a thousand-year-old fritter, what is a reward and what is a punishment, it must be able to distinguish clearly.

The Taoist priest's soul exchange technique needed to last for several days, and at Du Kang's request, his casting was not disturbed, but proceeded smoothly, and by the way, it was also for the sake of squatting behind the evil god obscenity.

In this way, Du Kang was able to concentrate on completing the formation.

……

"Whew...... That's it! Du Kang took a deep breath, only to feel very happy, quite a kind of high school evening self-study to do a complete set of math test papers, devote himself to it, from beginning to end of all the problems solved one by one, after the end of the feeling of finding that the answers are basically correct.

Du Kang's high school grades are not ideal, he is a science student, but in addition to the other subjects of language, mathematics and English, it is quite strange to say, it is not the influence of a hobby, but I feel that language, mathematics and English are easier to learn than physical and chemical students...... Or is it talented?

For example, in English, Du Kang has only junior high school vocabulary until now, he doesn't know anything about grammar, and he doesn't understand anything at all in the past tense and present tense, and the result is that he can get a good score, basically around 123, and he has never memorized any words or done test papers in college, and he has taken the fourth or sixth level naked, a typical language sense player.

Yes, that's right, it's the kind of player who successfully excludes the correct answer through a lot of reasonable and evidence-based analysis, and then asks him why he chose the correct answer, and he replies to you with a sentence of "language sense, I think you should choose this after reading it", the kind of language player who underplays!

It's okay to be defeated by people who study hard, but the roll is just the volume, and it should be recognized, but being killed by this kind of talent can really make people face the gap between people, and then feel deep despair and powerlessness.

"Du Gongzi's formation talent is really amazing...... It took me a long time to make these formations, and Du Gongzi, you are ...... like this."

Yunxiao's tone was full of emotion: "As the saying goes, 'There are people outside the world, and there is a sky outside the sky', and when I saw Du Gongzi today, I fully understood this sentence." ”

"Hahaha, it's just a gourd to draw a scoop, if I really want to think about it myself, I actually can't think of it, at most this can only be regarded as my degree of control over spiritual power, and it has to rely on the design of Yun Girl, in other words, Yun Girl is a technical talent, and I am purely doing manual work!" Du Kang said with a smile.

"Du Gongzi is too humble, you are not just copying, but improving...... It's amazing. Yunxiao smiled slightly wryly and shook his head.

"I mean, you guys don't talk to each other here, okay? I'm almost sleepy...... Why don't you install all the array disks first? Shi Yuye couldn't help but interrupt, she had been a little restless during this time.

Immortals are not omnipotent, and there are also proficient and unproficient spells, Shi Yuye's temperament determines that it is impossible for her to put much effort into the skills that this kind of immortal also needs to concentrate on and study calmly...... So just now it is basically equivalent to experiencing an elementary school student watching a high school student do math test papers.

Although I don't know how to feel it, it seems to be quite torturous.

At Shi Yuye's suggestion, Du Kang and Yunxiao stopped this meaningless mutual touting behavior, and then, Du Kang began to arrange the array under Yunxiao's guidance, and the process was very decompressive, probably ...... How about building a computer mainframe by yourself?

"Okay, I should be all connected, I only need to connect the leyline spiritual power, because it's a test, so don't connect to the backup spiritual power system first."

As soon as Yunxiao's words fell, Du Kang took control and connected the leylines with this formation.

The light emerged, and the complicated array patterns flashed on each array disk, and then all entered the normal operation, emitting a state of faint light, and the corresponding effects were also produced in the cave.

A small part of Du Kang's special request was separated from the cave, separated by a wall of light, and it was impossible to see anything through the formation with his eyes or divine thoughts.

"The next thing is to put the seeds in it...... What seeds should we use? Yunxiao looked at Du Kang.

"Rice." Du Kang opened his mouth without thinking, "Spirit rice, all kinds of spirit rice." ”

……

Modern, swaggering mountain.

After a short farewell to Yunxiao, Shi Yuye and Xiao Xuan, Du Kang, who returned to the modern era, came straight here.

After taking a deep breath, Du Kang stretched out his hand and entered the small formation area in the position of his impression.

As far as I can see, dozens of rice seeds are being piled up on the ground in perfect preservation.

Spanning more than 600 years, these seeds are still intact, and soon, they will be available.

Hundreds of years of secrets, for the people, for the people, for the people.
