Douluo Continent: This Tang San is different

Chapter 164 Convex Lens Imaging: The Camera Box

After the water-based volleyball was introduced, it quickly became popular at Xingluo Royal Academy, and some students even built similar venues in other sections of the river.

Clearly, Davis and his group weren't the only ones to discover the benefits of this training method.

Tang San didn't mind.

This is hardly a secret; anyone can imitate it, it's nothing special.

However, Tang San himself did not participate in this kind of training very often. Apart from cultivating the secret manuals in the Xuan Tian Bao Lu, studying the theory of martial souls, and discussing the production of soul tools with Guang Ling, he also formed a Blue Silver Emperor Rope under the waterfall, stood on it, and endured the impact of the more than 50-meter-high waterfall. At the same time, he practiced his footwork and improved his Ghost Shadow Sight.

For the first two weeks, Tang San would often fall, but after that, he gradually mastered the tricks and became more and more proficient.

Its movements became increasingly agile, ethereal, and elusive.

In the past, Tang San's movements were eerie and unpredictable, like a ghost, which was quite terrifying. But now, Tang San's movements are as light and agile as a fairy walking on water.

Therefore, Tang Sanjiang was named Xiaoyao Yufeng.

I hope that one day, with these steps, I can ride the wind and roam freely across the world.

In addition, after Xiao Wu obtained her third spirit ring, her speed increased, and she could take nine steps in mid-air. Tang San also added a special way to travel for Xiao Yao Yu Feng.

Ghostly Shadow is a movement-based skill, adept at hit-and-run tactics. It also relies on its improved version of Free and Easy Wind Control, but now it has a method focused on speed: Nine Steps to Heaven.

Therefore, the Free and Easy Wind Riding technique has two uses: one is a movement and fighting technique, and the other is a movement and running technique.

The traveler runs and takes nine steps to reach the sky.

According to Tang San's plan, he could take a step that would cover a distance of 100 meters, using the momentum of the Chaotic Cloak. The second step would cover 200 meters, and so on, increasing exponentially. By the ninth step, he could cover 25,600 meters, or 20.56 kilometers.

This speed is unmatched even by titled Douluo who are not skilled in speed.

However, Tang San can only use the fourth step now, leaping 800 meters in one step, and his soul power is consumed by nearly half.

Fortunately, his Blue Silver Emperor soul power recovered extremely quickly.

However, to use the ninth step, one needs to reach at least the Soul Saint level.

Furthermore, the physical body must reach a certain strength, otherwise it will break down due to excessive speed.

After Tang San finished his training for the day, Xu Xing, who had met Tang San, Xiao Wu, Guang Ling, and Huo Wu a few times before, came to visit him at the Star Luo Royal Academy.

However, apart from Tang San, the other three women had no impression of him at all.

"Hello, Tang San, do you remember me?" Xu Xing stood on the shore waiting, looking at his well-proportioned and taut muscles with envy in her eyes.

Born into the Star Crown Sect, even though he could consume millennium-level whale glue, he still couldn't possess a physical body as powerful as Tang San's.

When Tang San was training, he also thought about imitating his footwork, but he did not have the Purple Demon Eye and could not see Tang San's movements in the waterfall. Secondly, to perform the corresponding footwork, it is necessary to combine it with the corresponding soul power operation method. Just imitating the appearance will only backfire and may even harm oneself.

Therefore, Xu Xing gave up.

"I remember, Xu Xing of the Star Crown Sect. I wonder if you've come to understand the true nature of this world all these years?" Tang San's words were loaded with meaning, making Xu Xing somewhat uncomfortable.

However, he is now completely and 100% certain once again that Tang San, like him, is a time traveler from modern society, not the Tang Sect Tang San of the past.

"I've come to realize that this world is vast. I once wanted to get to know Zhu Zhuqing, but it was impossible. My family never gave me a chance to make contact..."

Xu Xing smiled bitterly, her face full of sorrow.

I thought that having transmigrated and been reborn into the Douluo Continent world that I knew, even without a system or any other cheat-like ability, I would surely be able to dominate the world, wield power over the land, and enjoy the company of beautiful women.

Then, he realized that he didn't have the Dragon Overlord instance.

Having innate full soul power is indeed impressive, and his cultivation speed is remarkable. This also means that the elders in the sect will not allow him to take too many risks.

For a sect, inheritance is the most important thing, not invincible strength among its peers.

Moreover, in the eyes of the elders, the Star Crown Martial Soul can only be used for support or control types. While it is possible to use other types, it will only result in mediocrity.

Tang San's "Self-Analysis and Positioning of Soul Masters" also indirectly illustrates that Soul Masters need to accurately identify the advantages of their Martial Soul and not neglect one aspect for another.

If you don't have the protagonist's luck, don't follow the protagonist's path.

That would only bury one's talent.

Therefore, when he was getting his second spirit ring, even though he felt he could absorb a thousand-year-old spirit ring after consuming whale glue, the elders in the sect examined his body and did not allow him to do so. Instead, they chose a spirit ring that was over nine hundred years old.

Also, he wanted to go near the Zhu family's residence to see if he could run into Zhu Zhuqing.

Then, he was taken away by the guardians arranged by the elders of the sect. Even when he threatened them, they ignored him and instead lectured him: "Zhu Zhuqing is Dai Mubai's fiancée from the Dai family. You can have contact with other girls from the Zhu family without any problem, but not with her, unless you can subdue the emperor and empress of Xingluo."

This made Xu Xing realize that the real Douluo Continent was different from the fan fiction. The fact that she was the prince's fiancée meant that he, as a disciple of the sect, could not approach her alone.

Although the Star Crown Sect supports the Star Luo, the Star Crown family is a subject of the Dai family.

However, precisely because they are subjects, they need to be even more mindful of their duties.

If he were to approach Zhu Zhuqing, would the current emperor of the Dai family think that the Xingguan Sect wanted to use him to participate in the competition between the two "Netherworld White Tigers"?

He joined the Star Luo Royal Academy and talked with Zhu Zhuyun without any problems, because she had already fused her martial soul with Davis, and the two were very close, so he had no chance to do so.

But Zhu Zhuqing is not suitable...

However, now, Zhu Zhuqing has returned to the Star Luo Empire, dissolved her engagement with Dai Mubai, and the martial soul connection between them has disappeared.

But he still didn't get the chance.

It's clear that Zhu Zhuqing seems to have feelings for Tang San.

She's not bad-looking at all!

"Now that you've figured it out, focus on improving yourself first. Don't dwell on things that aren't your concern." Tang San didn't know what Xu Xing had gone through all these years, but now that he had come to terms with reality, he figured Xu Xing wouldn't deliberately target him in the future.

"If I call you 'brother,' can you take me flying?" Xu Xing's eyes were full of expectation. If he couldn't beat him, he would join him. Anyway, this Tang San in front of him wasn't from the Tang Sect. He was from the modern society like him, so he should be easier to talk to.

"I am a sophisticated egoist; I can't get anything out of just talking."

With Xu Xing's talent, he might become the sect leader of the Star Crown Sect in the future, making him a promising talent. However, Tang San felt there was no need to become sworn brothers with Xu Xing.

Once he gains power, what is there to fear from the lower four sects like the Star Crown Sect?

There's no need to deliberately befriend them.

It wasn't that they were afraid of Xu Xing, the transmigrator, secretly betraying them, but rather that the current situation in the Star Luo Empire was uncertain, and making any investment recklessly could result in losing everything.

The Star Crown Martial Soul of the Star Crown Sect resembles a crown. Dai Lego can tolerate it, but it may not be so after Davis takes office in the future.

In the original story, ten thousand years later, the Star Crown lineage became the royal family of the Star Luo Empire, while the White Tiger lineage became princes…

Dai Mubai has no chance of ascending to the throne now, while Davis is more suitable to be emperor than Dai Mubai. In order to consolidate the throne, although he may not necessarily take action against the Star Crown Sect, he will definitely take corresponding policies to check and balance them, so that the Star Crown Sect will truly submit to the royal family.

Although Davis currently gives the impression of being a kind and generous prince to the rest of the Heaven Dou Royal Team, Tang San can see his pride and domineering nature beneath that kindness.

In this respect, Xu Xing is definitely no match.

"An equivalent exchange?" Xu Xing cursed the old fox inwardly, knowing that his plan to get something for nothing wouldn't work. He could only ask, "What do you want? And what will you exchange it for?"

"Various ancient books, collections, and martial soul information of the Star Crown Sect." Tang San said without hesitation, "And the bargaining chip in exchange is to plan a set of soul beast and soul ring combinations that are most suitable for your martial soul."

"Farewell." Xu Xing raised his hand in a fist salute, turned around and left.

Using various ancient books and materials from the Star Crown Sect to exchange for the selection of Star Crown Martial Soul's Soul Ring?

He's not that stupid!

The selection of spirit rings for Star Crown Martial Souls already has a system, so there's no need to follow Tang San's method. Moreover, he suspects that Tang San might be trying to trick him, just like when he mentioned "Heavenly Star Vine".

More importantly, Tang San lacked sincerity.

Couldn't you at least bring out some less important Tang Clan techniques?

Who are you trying to fool by offering just one set of spirit rings?

"It seems this guy still doesn't understand the importance of spirit rings to martial souls. Is it because he comes from a major sect that he has no concept of it?" Tang San understood that the things that transmigrators without cheat abilities most want to seize, besides immortal herbs, are the Xuan Tian Gong.

But if you call him "brother" and he teaches you the Xuan Tian Gong, then isn't this technique, which allows one to absorb the energy of heaven and earth without relying on a martial spirit, too cheap?

Currently, the only people who know the Mysterious Heaven Skill besides him are Guang Ling and Xiao Wu.

That's right, Xiao Wu was also taught the Mysterious Heaven Skill by Tang San.

"Third Brother, who was that guy just now? What did you talk about?" Xiao Wu walked over and asked curiously.

"Xu Xing, we encountered people from the Star Crown Sect when we were hunting souls in the Infinite Desert," Tang San said. "They wanted to trade with me, but they couldn't offer what I wanted."

"That little brat who analyzed for you why you should choose the Heavenly Star Vine for your third spirit ring?" Hearing Tang San mention it, Xiao Wu remembered, "What did that guy want to trade with you for?"

"Although he didn't say it explicitly, I know he wants my method of circulating soul power."

"He's definitely dreaming."

Tang San's meditation method, the Mysterious Heaven Skill, is extremely advanced and is undoubtedly one of the top cultivation methods in the world.

Xiao Wu was certain of this; her cultivation speed was so fast that only those evil cultivation methods involving devouring could compare.

"The gap between him and us will only widen, so there's no need to pay too much attention to it." Tang San understood that if a person cannot change the world, then they can only adapt to it.

Even modern time travelers can only be assimilated by their environment.

Now, Tang San is actually glad he wasn't born into the Clear Sky Sect; otherwise, his personality might have been changed without him even realizing it...

···

In the blink of an eye, three months have passed.

In two months, Tang San and the others will return to Tian Dou.

Guangling found Tang San and took out a new type of soul tool she had created that could be used for recording: the camera box.

This camera box combines three basic soul guide patterns: light, darkness, and space. Its internal structure is similar to a camera, and it can record images by injecting soul power.

The recorded images can also be projected onto a white sheet and played back.

However, since it was still an initial version, the focusing device was not yet designed, and there was no soul power storage device installed inside. Therefore, to play the video, a person had to hold the camera box, stand in the corresponding position, and continuously inject soul power.

"Not bad, you are indeed very talented in the research of soul tools. However, we need more people." Tang San did not expect that he had only explained the principle of pinhole imaging to Guang Ling, and she had actually made something similar. Moreover, it could record video and the picture played back was in color, but there was no sound.

This is the correct way to use a soul tool.

However, the research by just the two of them is ultimately limited by their limited energy, and they need others to join in.

"It's not that outstanding." Guang Ling was quite pleased with Tang San's praise.

"Let's go record the match between Yu Tianheng and his team and Xingluo Royal Academy's water volleyball team, then call them over to watch it together."

Tang San wanted to see how convenient this camera box was. If it worked, he might be able to broadcast it live across the entire continent when the Continental Advanced Soul Master Elite Tournament began.

cough!

There may not be enough time, but recording the scene and projecting it onto a white screen is still an option.

In terms of influence, how can a newspaper compare to a film and television production company?

When Xiao Wu, Huo Wu, Yu Tianheng and the others arrived at the small wooden house that Tang San had temporarily built by the waterfall, Tang San closed the windows and covered the room with an opaque cloth, making it pitch black inside.

"Captain, what are you doing? Playing hide-and-seek?" Yu Feng couldn't help but ask.

"You'll see soon enough," Tang San said, then turned to Guang Ling and said, "Show everyone your work."

Click!

A soft turning sound rang out, and light appeared in the room. Guangling poured soul power into the camera box, and light shone from the black transparent lens at the front, illuminating the white screen in front.

Suddenly, a scene appeared on the screen showing Yu Tianheng, Huo Wu, Oslo, Ye Lingling, Shi Mo, Shi Mo, and Yu Feng playing volleyball against Davis and others from Xingluo Royal Academy.

Although there was no sound, the clarity of the image made them feel as if they were sealed inside.

That was truly astonishing.

"Captain, how did you do that?" Yu Feng's gaze shifted from the curtain to the camera case in Guang Ling's hand, and he couldn't help but seek an answer from Tang San.

"This is a camera box. I provided the basic imaging principle, and then Guangling was responsible for its research and production. You've all seen its function: it records images and then plays them back." Tang San gestured for Guangling to stop inputting soul power, took the camera box from her hand, and introduced it.

Ye Lingling asked, "What's the principle behind its ability to record images?"

"Light and shadow." Tang San said, cutting a small round hole in the curtain of the window, letting in the outside light, which fell right onto the white screen that had been playing the video.

At this moment, the image on the screen is of the waterfall outside, with people walking along the rocky bank.

Unlike the previous video played by Guangling using a camera box, the scene on this one was very blurry, as if covered by a layer of gauze, hazy and indistinct, and it was also upside down.

The pinhole imaging experiment was first demonstrated by Tang San to Huo Wu, Yu Tianheng, and others.

"This is the basic principle behind how the camera box can create images," Tang San said. "Essentially, it's just the reversal of light to present the image. To use an example you can understand, it's like a person's image being reflected on the surface of water, and this method reflects the external environment onto the walls of the room."

"This method can also be used by ordinary people without soul power."

"It just can't be recorded."

Ning Rongrong asked, "What's the use of an ordinary person doing this? The image is upside down and so blurry, it's dizzying to look at."

Tang San took out a convex lens and placed it over the small hole.

Instantly, the image on the wall became incredibly clear, with the same clarity as the image that Guangling had previously played back using the camera box.

The only difference was that Tang San attached a convex lens to the small hole.

Ning Rongrong went closer to take a look and discovered that the object in Tang San's hand was indeed a lens that was thin at both ends and thick in the middle, and not some other soul tool. She was astonished: "Just a lens, and it can make the image so clear? What kind of soul skill is this?"

"It's just a phenomenon. Light has speed and direction, and light refracts when it passes through a lens." Tang San took the convex lens, pulled back the curtain on the window, and handed it to Ning Rongrong. "I think there must be quite a few elders in the Seven Treasure Glazed Tile School who need glasses to see the words clearly, right? Those lenses are convex lenses."

Ning Rongrong placed the convex lens on a book, and the words on it appeared magnified through the lens.

Then, Tang San drew a simple diagram of convex lens imaging on the paper, showing that light has direction. After passing through a convex lens, the light rays will focus at a point and then disperse. At the point of focus, the light rays are concentrated into one point and become extremely hot.

Concave lenses, on the other hand, cause light to diffuse, thus reducing heat.

Ning Rongrong seemed to understand the principle of image formation in a camera, except for the extra step of recording the image. Then, as if remembering something, she suddenly asked, "So, isn't our human eye also a kind of convex lens?"

"You could say that the human brain is like us, who were previously locked in darkness. The pupil is like a small hole I made in the curtain of the window, and the convex lens is like the transparent, adjustable soft rubber lens in our pupil."

Seeing that Ning Rongrong could apply what she learned to other situations, Tang San was naturally willing to say more. "As for why the scene was upside down, it's because the previous room wasn't a real human brain and couldn't imagine it. Our brains are extremely complex and can actively adjust and straighten the scene."

"As for why the image played back from the camera box is upright, it's actually quite simple. The recorded image is upside down inside the camera box, and when it's played back, the light passes through the convex lens and the small hole, naturally turning the upside-down image into an upright one."

The environment has a significant impact on a person's character, even for adults whose values ​​have already matured.

To give an extreme example, a person who is well-off and mild-mannered will inevitably become cunning if they are suddenly placed in an environment with scarce resources, provided they "survive" for a period of time.
