Du Fan squinted at Ren Ziwen, with a half-believing expression, and said, "Then tell me, what are the advantages of this walkie-talkie?"

"First of all, the signal is good ......"

The first sentence that Ren Ziwen said made Du Fan couldn't help but roll his eyes several times.

"The most important thing is that the walkie-talkie I developed ignores the constraints of space, no matter how far apart the people on both sides are, they don't even have to think about whether they are on the same interface, as long as the time they are in is synchronized, they can have a conversation through the walkie-talkie.

Also, I'm working on a video walkie-talkie right now, and I believe it won't take long for it to come out. ”

"So awesome?" Du Fan was stunned when he heard this.

"A must!" Ren Ziwen looked proud.

"Give me one too. Du Fan thought for a moment and added: "One is not enough, at least ten." ”

"Not so much, just one for you. Ren Ziwen said, turned over his hand and took out another stone tool and threw it out.

"How do you use this thing, dial-up?" Du Fan asked curiously as he played with the stone walkie-talkie in his hand.

"It's not as complicated as you say, you don't have to do anything, just pick it up and talk directly, but this kind of walkie-talkie can only be regarded as a semi-finished product, and it can only be used one-to-one between the two walkie-talkies, and the follow-up needs to be improved. Ren Ziwen explained.

"That means, if you talk to me, Xiao Yun, and Anu, you still have to prepare three walkie-talkies?

"Yes, that's what it means, but I've found a way to improve it, as long as the theory is realized, then this walkie-talkie is really similar to a telephone, everyone only needs a stone tool. Call whoever you want. Ren Ziwen said with anticipation.

"Okay, you can study it slowly, I'm optimistic about you. Du Fan gave Ren Ziwen an encouraging look, he was completely convinced by the scientific research spirit of this test maniac, he was too thoughtful, and the key was not utopian. Every time, I can make some scientific research results.

Ren Ziwen raised his arm, threw a storage bag to Du Fan, and said, "Here, according to your requirements, the ghost guide stick has been dusted, and now it has recovered to its original appearance and reached the real high-grade level."

I have partially sealed the Shangshan Ruoshui Sword, and now the power of this magic weapon is between the top grade and the acquired best, and I only need to use a little means. can be unblocked immediately.

There are also twenty pairs of memory rune woods in it, you pay attention, two of the memory rune trees that exist separately are positioned, and the location coordinates are here, if you are in danger outside, you and Baili Qiu can immediately crush these two memory rune woods, and then you can return to the governor's palace. ”

"I'm not going to say anything kind to you. Du Fan smiled, and then thought of something. With one hand, he slapped the storage bag, and immediately flew out of three pairs of memory runes. He dismantled these memory runes one by one, and then handed the three separate memory runes to Ren Ziwen.

"Brother Du, what are you ......" Ren Ziwen was puzzled.

"If nothing else, I will return to the Kyushu Continent in the near future, and then return to the Qixia Sect, after arriving at the sect. I'm completely safe, and I don't have to worry about it anymore.

At that point, I'll crush all three memory runes and use them for positioning, if you're bored here. You can go to my side and have a look, Xiao Yun and Anu are the same. Du Fan smiled slightly and explained.

Ren Ziwen's eyes lit up, and he said with a smile: "This idea is good, with the memory rune wood, from now on, you and I can shuttle back and forth between the two continents, but seriously, the more things like Huangtian Lingmu, the better, if you can, you still have to find a way to get more." ”

"I don't need you to say this, I know it, it's just that this thing is rare in the world, and it can't be obtained by chance, of course, if I really meet it, no matter how much it costs, I will get it to ......" Speaking of this, Du Fan paused, his eyes fell on Ren Ziwen, and said: "This time, you haven't forgotten to use the memory rune wood to locate in that strange space, right?"

"Of course I haven't forgotten that it's been positioned. ”

"What about you...... Try it?" Du Fan's eyes lit up.

"Forget it, maybe there will be some variables, I'll study it slowly after you're gone. Ren Ziwen shook his head.

"Well, that's fine. ”

"Brother Du, how do you plan to return to the Kyushu Continent?" Ren Ziwen asked.

"I don't know yet, but it's going to be soon. Du Fan suddenly thought of Tan Xi, who was still unconscious, which was also a reason why he was in a hurry to use the space-time tripod, and only the passage of time in that strange space could leave enough time for Tan Xi to wake up.

"Is it reliable?" Xiao Yun couldn't help but interject.

Du Fan glanced at the woman, smiled and said, "Don't worry, it's quite reliable." ”

"Young Master. Anu's figure flickered a few times, and when he came to the three of them, Baili Qiu followed in the distance, and his speed was also very fast.

"The peak of the sixth layer of the Qi refining period!" Du Fan immediately separated a wisp of divine thought, swept it towards Baili Qiu, and his expression changed slightly.

"Everything is done?" Ren Ziwen smiled at Anu and asked softly.

"Well, these storage bags contain materials related to alchemy and refining weapons respectively, and in these two spirit beast bags, there are second-level demonic beasts and middle-level demon beasts that the young master wants. ”

Anu handed a large number of bags to Ren Ziwen, but Ren Ziwen only left two spirit beast bags, and the rest of the storage bags were directly thrown to Du Fan.

Ren Ziwen casually picked up a spirit beast bag and shook it, the black light flickered, and a demonic beast like a sheep and a deer fell to the ground, the eyes of this beast were open, but it looked a little sluggish, and there was a talisman attached to the top of the head for suppression.

Ren Ziwen didn't say a word, and directly threw this demonic beast into the space-time tripod, and then began to operate.

"Apprentice to meet Master. At this time, Baili Qiu came, and immediately gave Du Fan a deep salute, and the little guy's black and white eyes obviously flashed a trace of joy and reassurance, but he was withdrawn and indifferent, but he did not say a word of greeting.

"Don't be polite, you go to the side and get ready, and I'll take you away later. Du Fan said with a smile.

"Yes, Master. After Baili Qiu saluted again, he walked away, directly ignoring Ren Ziwen, Xiao Yun and others.

Anu was a little angry when he saw this. When he wanted to say something, he was stopped by Xiao Yun.

"Brother Du, come here. Ren Ziwen suddenly shouted.

"What's wrong?" Du Fan walked over.

"I've completed a time travel, and the time of this monster is three years and ten months. Ren Ziwen said.

"Well, this time is the same as the time of the last experiment, erasing the space-time mark. Let's make a second shuttle. ”

Ren Ziwen nodded, took out some materials, and after some operations, took out a few high-grade spirit stones again to activate the space-time tripod.

"Seven years and eight months!" After a while, Du Fan and Ren Ziwen glanced at each other and said in unison.

"It seems that there is no problem with our previous guess, and the second time we stayed was exactly twice as long as the first time, but we don't know the extra time. Is it added or multiplied? Du Fan's face looked thoughtful.

"Let's make sure. Ren Ziwen shook out the demon beast in the other spirit beast bag and threw it into the space-time tripod, and then began a skillful operation.

"The first shuttle of this demon beast lasted two years and eleven months, and the second time was five years and ten months, and the guess that the time was twice as long can already be determined. Ren Ziwen came to a conclusion and said, "Brother Du, what was the duration of your last shuttle?"

"Four years and eleven months. ”

"So to speak. Your journey through time and space will last at least nine years and ten months, will I blink an eye later? Are you going to become a Yuan Infant power?" Ren Ziwen looked strange.

"How is this possible, at most it is the middle stage of Jindan. Du Fan shook his head and smiled, but he was thinking in his heart: "Yuan Infant Period...... It's so far away, even if I finish all the Lingshu Sutras in one go, I guess I won't be able to reach that height, not to mention that the Lingshu Sutra is so precious. How can I waste it now? This thing is one less volume after one volume. ”

"You think about it again and see if there is any other need, it's still too late to prepare, it's too late to enter, after all, there is only one chance to steal time in a short time. Ren Ziwen instructed.

"No more. Du Fan thought for a long time. I felt that there was no problem, and immediately my body flickered, and I instantly appeared in the space-time tripod.

Ren Ziwen took out several high-grade spirit stones and buckled them in several grooves in the space-time tripod, and Du Fan played a magic decision.

......

Du Fan only felt that his eyes were dark, his head sank, and he lost consciousness.

Maybe a long time later, maybe just a moment, when he returned to normal, he found himself in a wonderful world, where there was no sky, no earth, no up, no down, only endless water-blue points of light, and the eyes were vast.

"It's weird, whether it's the water aura, or the surrounding scene, or the feeling in my heart, there is no change, the two shuttles before and after won't be the same space, I was in a hurry just now, and I forgot to communicate with Ren Ziwen......"

Du Fan's eyes and thoughts swept around, and after a while, he came to such a conclusion.

"This time the stay is destined to be very long, so why don't you go to the edge of this space like last time? Du Fan thought so in his heart, and suddenly his figure shook, and he sped away in a certain direction.

It may be his luck, or it may be that his speed soared after advancing to the Golden Pill Stage, and in less than ten days, he appeared on the edge of this world.

At the edge of the world, there is still an existence similar to a space barrier, almost transparent, difficult to distinguish with the naked eye, only divine thoughts can detect it, if the body hits it, it will be bounced open by the barrier.

Behind the barrier, most of the area is pitch-black, which looks very distant and deep.

It seems that there are stars scattered in the starry sky at random, and there seems to be no law.

It is not until far away that you can see the flow of stars and the surrounding constellations, which are countless stars gathered together, outlining abstract and vivid patterns, in the darkness and endless nothingness, as if free from the shackles of time and space.

Du Fan stopped and looked at it for a long time, although this strange scene, he was not the first time to appreciate it, but at this moment his heart was still full of shock, even fear, he suddenly realized that no matter what kind of thing, in front of infinite time and endless space, it seemed so insignificant, and a person. For the vast universe, not even a speck of dust counts.

After a cup of tea, Du Fan retracted his gaze, retreated a few miles, and released spirit insects and spirit beasts such as Xuanmu silkworms and one-legged birds, and threw out resources such as empty mulberry leaves, magic cores, and dogwood fruits. Let them cultivate on their own, while he himself sits cross-legged and gathers his mind.

For Du Fan, going to the edge of the world to take a look was purely a whim, and it had no substantive meaning to him, in his plan, after shuttling to this space. The first thing to do is to consolidate the cultivation and break through the period of stability.

When his state was adjusted to the best, his wrist suddenly flipped over, and several pale cyan demon pills and the corresponding amount of Hua Dan water emerged, he didn't say a word, he immediately swallowed a demon pill and a bottle of Hua Dan water, and then the exercises worked. Carry out refining.

An hour later, the demon pill was refined. The stabilization period has advanced a bit as expected.

Du Fan looked inward, felt the changes in himself, and measured the energy strength of the demon pill and the bearing capacity of his body, and after a while, he came to a conclusion, even if it is conservative, swallowing twenty or thirty demon pills at the same time should not be a big problem.

He waved his arm. He swallowed the remaining more than 20 light cyan demon pills and the same amount of Hua Dan water into his stomach in one go, so in his viscera, there was a wonderful scene of more than 20 Hua Dan water slowly rotating around the light cyan demon pill.

An hour later, these more than twenty pale cyan demon pills were refined by him.

Next. He directly took out forty light cyan demon pills, as well as forty bottles of chemical pill water, and swallowed them in one gulp.

A month later, Du Fan successfully broke through the stable period of the early stage of Jindan, and really stepped into the early stage of Jindan, if there is no major accident, there is no danger of falling into the realm, and he is completely stable in the realm of Jindan.

For Du Fan, who was taking the demon pill to over-stabilize the period, before that, the time to break through the stability period was very regular and very fixed.

For example, when he had just advanced to the Great Perfection of the Qi Refining Period, the stabilization period lasted for half a month, the early stage of foundation building was one month, and the middle stage of foundation building was two months.

Although he had another opportunity in the later stage of foundation building and the great consummation of foundation building, it didn't take too long, but the law of this stabilization period was already obvious, in the case of only taking the demon pill, each additional realm would last twice as long.

According to this law, in the early stage of Jindan, if he wanted to break through the stable period, he had to take at least sixteen months of demon pills, but the actual situation was that it only took him one month to pass this stable period with a leap forward.

The reason for this phenomenon must be inseparable from the Lingshu Sutra and the Danhai Sutra, it seems that his cultivation qualifications, under the transformation of these two anti-heaven scriptures, have really changed from the first waste material in the world at the beginning, to today's cultivation genius.

Du Fan exhaled slowly, and then opened his eyes.

"Before continuing to cultivate, it is necessary to study the elixir essential oil and the golden wind and jade dew. ”

With a wave of Du Fan's sleeves, three sets of experimental instruments that had not been used for a long time were presented and placed side by side in front of him.

"The four most common pills in the Jindan period to improve cultivation are Jinsheng Dan, Haoyue Dan, Jingyang Dan, and Ning Hua Dan, which are suitable for the early, middle, and late stages of Jindan, as well as the Great Perfection, even if this pill is refined into Dan essential oil, for me now, the effect will not be too great, just start studying it from Haoyue Dan. ”

"Even though the elixir essential oil in the Jindan period is a little troublesome to get, with my biological attainments, most of them can still be studied, but it's hard to say any further.

In the long run, the Golden Wind Jade Dew Spiritual Liquid is the right way, it can always grow with me, and the elixir essential oil is only an excessive means after all, and it will be eliminated sooner or later.

Fortunately, I already have some eyebrows for the cultivation plan of the Golden Wind Leaf and the Gyokuro Flower, and after repeated deductions, the feasibility is extremely high, but in a short period of time, the Golden Wind and Gyokuro Spiritual Liquid cannot be produced on a large scale, so the cultivation of the Golden Wind Leaf, the Gyokuro Flower and the refining of the elixir essential oil need to be carried out simultaneously. ”

"When it comes to cultivating golden wind leaves and gyokuro flowers, it starts with the holy water that returns to the roots......

When he was on Fallen Leaves Island, Xiao Yun was still a killer of fallen leaves returning to his roots, Du Fan once broke into the temple of falling leaves returning to his roots with this woman, and Xiao Yun's ultimate goal was to restore her appearance with the help of holy water, and after the woman's appearance was restored, the holy water was not completely used up, so Xiao Yun gave the remaining holy water to Du Fan like a Buddha with flowers.

Du Fan raised his hand and grabbed it, and the bottle containing the holy water appeared in his hand, he looked at the water in the bottle, smiled faintly, and whispered: "The holy water has the effect of generating muscle and reshaping the body, hehe, to put it bluntly, isn't it to promote cell division and growth......"

Golden Wind Leaf and Gyokuro Flower have no seeds and cannot be cultivated and mass-produced through normal means, but this matter is not inexplicable for the genius biological scientist Du Fan, and one of the first professional terms that comes to his mind is ...... Vegetative propagation!

Vegetative propagation is a kind of plant reproduction, not through the sexual route, but the use of roots, leaves, stems and other vegetative organs to reproduce offspring, this reproduction method can not only maintain the excellent characteristics of the cultivar, but also reproduction speed is faster.

To put it simply, it is to cut a small rhizome or branch from the golden wind leaf and gyokuro flower, and then place it in a special environment to grow, and finally this small rhizome or branch will become a new spiritual herb.

This is vegetative reproduction, or asexual reproduction, without seeds at all! )
