The Legend of Immortal Yun

"Sir, all models have been tested successfully, please feel free to command." Xiaoxing reminded.

"Great! How long is the estimated construction period?"

"Forty days."

"Fortunately, it seems that this trip to Linyu is finally coming to an end..." Li Yun said with a sigh of relief.

Nearly three years have passed since setting off from the Human Realm. The trip to Linyu can be said to be Li Yun's longest trip so far.

Moreover, it is estimated that he will stay for a while before leaving, because there is still the last stop of the Fire Lin Realm and the plan to cure the plague of the Lin Clan.

However, the harvest is also full. Not to mention other things, just the fairy spirit obtained from these large formations, as well as the huge amount of scraps and Linyu specialties obtained later, allowed the Tianyun world to expand significantly and further expand its size. promote!

"Sir, Fairy Wenhui and Du Lin have gone to the wild world." Xiaoxing said.

"They went to the wild world?" Li Yun was slightly startled.

"Yes, after leaving Huang Daxian Palace, the two of them originally walked towards Linyu, but after walking for a while, they turned around and headed towards the Wilderness Realm."

"It seems like it's going to be lively there again..." Li Yun said with a smile.

"Yes. Last time, people from all the tribes in the spirit world sent out talismans. Now people in some nearby realms have received the news and started organizing people to go there. There will only be more and more people going there, because The allure of the fairy grass and elixir is extremely huge.”

Li Yun sighed slightly when he heard this. Treasures can always arouse the covetousness of countless people, making them take risks to fight for them. This is the daily life in the Xuanling world, but in other universes, is it not the same? Wealth touches people's hearts. Many people cannot keep their indifference and calmness in the face of huge wealth. Even those who are unable to compete for it will still be lucky and hope to join in the fun. Maybe good luck will land on them. But often, what they get in the end is not good luck, but bad luck...

He asked: "Where is that literary youth?"

"He was also following the two of them."

"Didn't Fairy Wenhui and Du Lin discover him? Even if they didn't discover him, the weapon spirit of the small nest should have discovered him, right?" Li Yunqi asked.

"They found it, but there was nothing they could do, because it was impossible to catch him, and even if they did, they probably wouldn't be able to catch him, so they had to endure it," Xiaoxing said with a smile.

"good.

Wen Qing dared to follow them because he had something to rely on. The lightning shuttle he threw out last time was extremely fast, and it was impossible for Fairy Wenhui and the others to catch it. "Li Yun agreed.

"That's right. That lightning shuttle is very unique. It flies at lightning speed. I'm currently studying it..."

"Oh? How do you think it's done?"

Li Yun also remembered that after Wen Qing threw the lightning shuttle, a huge rain-like cloud soon appeared, and not long after, linear lightning appeared, and the lightning shuttle turned out to be in that lightning It glides so fast that people are stunned to see it.

At that time, he had some thoughts on the operating principle of the lightning shuttle, but because he had been busy, he did not study it in depth.

Xiaoxing said: "It should be designed according to the will of lightning. It is mainly propelled by the high-voltage kinetic energy of lightning, rather than relying on the large spirit gathering array to provide energy."

"Lightning Dao intention? You mean...from high pressure to low pressure?!" Li Yun was slightly shocked when he heard this.

Through pre-universe research, it has actually been proven that the formation of lightning is not very mysterious, but is a strong discharge phenomenon between clouds, clouds and ground, or between various parts of the cloud body.

Positive and negative charges are usually generated by the formation of cumulonimbus clouds. The bottom layer of the cloud is negative and the top layer is positive. Positive charges are also generated on the ground, which move with the clouds like a shadow.

Positive charges and negative charges attract each other, but the air between the clouds and the ground is not a good conductor. Therefore, the positive charges on the ground rush to the tops of trees, hills, tall buildings, and even the human body in an attempt to Negatively charged clouds meet; while negatively charged branch-like tentacles extend downward, closer to the ground.

Finally, the positive and negative charges finally overcome the air barrier and connect with each other. At this time, a huge current rushes from the ground to the clouds along a conductive airway, producing a bright and dazzling flash, which is lightning.

In the previous universe, a lightning bolt might have been only a few hundred meters long, but could have been up to several thousand meters long. The temperature of lightning ranges from 17,000 to 28,000 degrees Celsius, which is three to five times the surface temperature of the sun.

The extreme heat of lightning causes the air along its path to expand violently, causing the air to move rapidly, forming waves and making sound. This is thunder.

Of course, what is described here is only the most common phenomenon of lightning and thunder, and reality will be more complex and diverse.

In addition to the lightning between the cloud and the ground, there are also currents caused by the positive charge area and negative charge area inside the cloud, as well as the voltage difference between different clouds, all of which will form lightning!

It can be simply understood that lightning is the rapid movement of charged particles from a high-pressure area to a low-pressure area. This is the expression of the Taoist meaning of lightning that Li Yun first thought of after hearing what Xiaoxing said.

Xiaoxing said: "Yes, the Lightning Shuttle should take advantage of the characteristics of cumulonimbus clouds to form a wide range of high-pressure and low-pressure areas, and then be quickly pushed to the low-pressure area by the high-pressure power. The role of the Spirit Gathering Array is It should be used to promote the formation of high-pressure areas and low-pressure areas, rather than be used for power. Therefore, the lightning shuttle is not only extremely fast, but also very energy-saving!"

"This design idea is so wonderful! It shows that the weapon refiners in the immortal world are really extraordinary!" Li Yun praised heartily.

"Hey, this Taoist meaning comes from the analysis of our previous universe. In the Xuanling world, it is just their perceptual understanding. The weapon refiners in the fairy world must have discovered that they can use this push based on their research on the Tao of Lightning. However, if we study it carefully, we will find that this is only the initial stage of the way of lightning." Xiaoxing said with a smile.

Li Yun was overjoyed when he heard this and asked urgently: "What did you find?"

"Sir, there are many forms of lightning, including linear lightning, sheet lightning, ball lightning, ribbon lightning, bead lightning, rocket lightning, blue lightning, red lightning, white lightning, purple lightning, black lightning Lightning... there are even super lightning, submarine lightning... each type of lightning has its own different characteristics, not all of them simply go from high pressure area to low pressure area, there are also some ghost-like lightnings, which often occur in every lightning phenomenon The final stage of lightning cannot be seen or detected by ordinary people. Therefore, the formation of lightning seems simple, but it is also extremely complicated. Without a profound Taoist meaning, it cannot be fully understood." Xiaoxing said.

"this…"

Li Yun was dumbfounded and his mind was spinning, trying desperately to digest the information Xiaoxing said.

Xiaoxing continued: "Lightning and thunder go hand in hand. Generally speaking, you see the lightning first and then hear the thunder. In fact, the two happen at the same time, but the speed of lightning is slower than the sound of thunder. Much faster. Your Excellency has a deep understanding of the meaning of thunder. In the Xuanling world, whether it is ordinary sky thunder, real thunder, or colorful tribulation thunder, they all contain high temperature and heat, which causes the gas to expand violently, thus producing thunder. At the same time, a certain high-pressure area or low-pressure area will be formed, and various lightning phenomena will occur."

"Indeed." Li Yun agreed.

"So, the lightning shuttle only uses the phenomenon of linear lightning in lightning. Xiaonu also found that thunder roared during its use, indicating that the power of thunder accompanying lightning has not been utilized. This is What a huge waste!”

"Yes, if this power of thunder can be channeled into the driving force, then the speed of the lightning shuttle can be increased by at least one-third!" Li Yun analyzed.

"Yes, of course, this also requires that the quality of this lightning shuttle is excellent and can withstand this crazy speed, otherwise it will definitely explode due to overheating and brittleness!"

"Listening to what you said, why do I feel that the way the lightning shuttle moves forward is similar to my shukuchi method?" Li Yun teased.

When he performed the Shuchi Technique, he also created a realm power space and used the gathered realm power to push himself forward, which was extremely labor-saving.

Xiaoxing smiled and said: "It is indeed quite similar. Maybe at a certain level, different techniques and artifacts actually have the same purpose."

"It makes sense. In addition, the lightning shuttle should use formations to generate linear lightning based on the characteristics of cumulonimbus clouds, right?" Li Yun thought.

"It is indeed a formation, let's call it the cumulonimbus formation, and then using the power of the spirit gathering formation to drive its operation, linear lightning was generated in a very short time, and the lightning shuttle began to fly in the lightning Got it!"

"If we can use formations to form various types of lightning, wouldn't we be able to fly with more characteristics?" Li Yunzhan said.

"Of course! These formations can not only drive flying boats and shuttles, but also various weapons and objects. The application prospects are extremely broad!" Xiaoxing said proudly.

"Wenqing must not have thought that just a lightning shuttle can bring us so many design ideas. The lightning products we will display in the future will completely amaze them!" Li Yun praised.

"That's for sure!" Xiaoxing said confidently.

In fact, after seeing Wen Qing use the Lightning Shuttle, Xiaoxing had already begun to study it, so he could immediately discuss it with Li Yun to such a profound level. With his ability, once he started to study it, The speed is so fast that you can catch up with and surpass others in no time.

Since Li Yun had to direct the restoration project, he could not escape to Tianyun for detailed research, so he could only continue to direct while discussing with Xiaoxing...
