Douluo Continent: I am a biologist, and I have awakened a weapon spirit?

"The rotation speed is much faster than in the music box, it must be a problem with the materials," Tang San commented.

Chen Feng pondered for a moment and said, "Perhaps we can introduce a new concept called soul guidance performance, which is the ability of soul power to be transmitted in metal. The greater the loss during the transmission process, the worse the soul guidance performance, and vice versa."

Tang San understood, "In other words, the metal used in the music box is not as good as Star Soul Mithril in terms of soul guidance performance, which is why there is such a big difference in their rotation speed."

Chen Feng nodded. "Yes, this must have been intentional. After all, it's just a music box. If it spins too fast, it will only create noise. Also, Xiao San, I'd like to try something. Have Uncle Hao put some soul power into it and see if the rotor's speed changes."

Tang San handed the item in his hand to Tang Hao, who then poured his soul power into it as instructed. Visibly, the rotor's speed increased several times over.

"As expected, we can enhance output by improving both soul power strength and material properties," Chen Feng said, quite surprised.

Tang San surveyed the wildly spinning metal structure before him, his mind swirling with ideas. He gestured as he spoke:

"Xiao Feng, do you think if we put a quiver on this and add a metal baffle to the rotor, it could fire bolts at an extremely high speed?"

Chen Feng smiled and said:

"Why must we limit ourselves to crossbows? We can make sharp metal rods and cut several blood grooves on them. This way, the metal rods can fit together very tightly, which is something crossbows can't do because the arrowheads are too cumbersome."

"But what's the point of doing this?" Tang San asked, puzzled.

Chen Feng explained, "If we use crossbows as you suggested, then even if the rotor rotates faster, the speed at which the crossbow bolts descends will not change, and the rate of fire will ultimately be limited. However, if we use a sharp metal rod with a blood groove, we can compress it through a structure like a spring, and then the speed of loading... loading arrows will be greatly increased."

"There's no need to worry about the lethality being insufficient. We can simply make the metal rod thicker, or we can make the tip and the back of the metal rod with two different metal materials. The back can be made of a tougher metal, while the tip can be made of a hard and brittle metal and then split horizontally and vertically. This way, once it enters the human body, the tip will explode directly into a flower shape. However, this will greatly reduce its penetrability."

"Hiss~" Tang San gasped, momentarily unsure whether he or Chen Feng was a true member of the Tang Clan.

Oh no! Am I the imposter?

Tang Hao also gave Chen Feng a deep look, thinking to himself that this kid usually seemed kind and gentle, but he turned out to be a big culprit.

He fiddled with the metal rotor in his hand, his expression slightly complicated. Although the weapons Chen Feng and Tang San mentioned couldn't hurt him, that was only true for now.

Judging from what the two of them just said, there's still room for improvement. If it continues to develop like this, it might be okay for Title Douluos, but for Soul Masters at lower levels...

“Using metal rods as projectiles alone won’t work,” Chen Feng continued. “We can work on the projectiles themselves. For example, we can add some explosive materials and make the whole structure bigger. This will greatly increase its power.”

Tang Hao & Tang San: Please, have some decency.

But no matter how much the Tang father and son grumbled inwardly, they couldn't stop Chen Feng from combining the power structure and gunpowder in front of him.

It doesn't necessarily have to be gunpowder. If better explosives are discovered in the future, or a suitable core magic array is obtained, then it can also be considered as a launcher.

Wait a minute, why did I suddenly think about weapons? We should be considering how to apply them to industrial production first. It's all Xiao San's fault for leading me astray. Chen Feng's thinking has finally come to a stop.

After silently reciting "harmony is precious" for a while, Chen Feng pointed to the metal structure in Tang Hao's hand and said:

"I think we should give it a name. This kind of power structure will definitely be widely used in the future."

"It's driven by soul power, so why not call it the Soul Power Rotation Mechanism?" Tang San suggested.

"Or to put it more simply, how about a soul power engine?" Chen Feng asked.

"It feels pretty good too." Tang San nodded in agreement.

Chapter 263 I Travel with the Wind

After successfully creating the Soul Power Engine, Chen Feng began to consider its application areas.

Needless to say, the weaponry is another matter.

During my conversation with Tang San just now, we already had a general framework for this.

What we really need to consider is how to apply it to industrial production.

This raises the question of how to convert the rotational force provided by the soul power engine into the push and pull force required for certain industrial activities.

For example, metal forging is an essential process in industrial production, and Soul Guidance Industry will not be without this process either.

The problem was that Chen Feng had long forgotten his physics knowledge and couldn't think of any good ideas for the time being.

Having no other choice, he had to consult with Tang San.

"Turning rotational force into pushing and pulling force? What's the use of that?" Tang San hadn't yet shifted his mindset from that of a craftsman.

After listening to Chen Feng explain his thought process, he suddenly realized:

"You mean we can delegate some repetitive, mechanical tasks to soul tools, while humans only handle tasks requiring creativity and skill?"

Chen Feng nodded slightly. "This is the ideal state. It was definitely impossible to achieve this level at the beginning, but if the forging step can be completed by the soul tool, then the production efficiency of the soul tool will definitely be greatly improved. This is how to make soul tools using soul tools."

"What a brilliant idea," Tang Hao exclaimed, then shook his head. "However, this will definitely affect the quality of the metal forging, which is a downside."

Chen Feng smiled slightly, "It will definitely have an impact, but it won't be a problem, because doing it this way will greatly increase production capacity. It's much faster than relying on craftsmen to hammer away one hammer at a time. Uncle Hao, think about it. Take the kind of weapon that Xiao San and I were just talking about, let's call it the Soul Guided Crossbow. Which one has greater destructive power: firing 10,000 medium-quality Soul Guided Crossbows at once or firing 100 high-quality or even top-quality Soul Guided Crossbows at once?"

Tang Hao imagined the scene and had to admit that the former was far more terrifying.

“That’s right, this is the victory of the soul guidance industry’s production capacity. Moreover, soul guidance technology can also improve, which can improve the quality of the soul guidance devices produced, thereby affecting the quality of the metal produced. And this quality will be very stable. On the other hand, the blacksmith’s skills are uneven. It is self-evident which one is superior.” Chen Feng spread his hands and said.

Tang San also realized the power of the Soul Guidance Industry and began to think about the problem that Chen Feng had just raised.

"Converting rotational force into push-pull force..."

Countless mechanical structures flashed through his mind, constantly being disassembled and recombined, with new structures added to them, gradually forming two mechanical structures that met the requirements.

Tang San took out paper and pen from the Jade Snow Ice and began to draw quickly, soon producing two structural diagrams.

Chen Feng leaned over to take a look, feeling somewhat confused, but fortunately Tang San began to explain:

"I came up with two solutions. The first is to use a turntable, a long handle, a slider, and a slide rail. One end of the long handle is connected to a certain edge of the turntable, and the other end is connected to the slider. Both of these connections use a wheel and axle structure so that they can rotate. In this way, when the turntable starts to rotate, the force can be transmitted from the turntable to the slider, causing the slider to push and pull back and forth on the slide rail."

After the explanation, Chen Feng finally understood the principle behind the first picture and asked:

"And what about the second picture?"

"The second picture is inspired by a hammer."

"hammer?"

"Well, look, if we hollow out the middle of the hammer head and make a 'I'-shaped track, and then fit it onto the fixed point on the edge of the turntable in the first picture, then as the turntable starts to rotate, that fixed point will also move the hammer up and down, and the hammer handle will also start to push and pull." Tang San summoned the Clear Sky Hammer and explained with gestures.

Chen Feng also understood the principle of this structure. He just lacked creativity in mechanical aspects, but his brain was still very useful.

"So, Xiao San, which of these two structures do you think is more suitable for forging metals?"

“I think the first diagram is more suitable. Forging metal requires a lot of effort, and the first structure is relatively simple and straightforward, making it less prone to failure. Of course, we still need to experiment with it.” Tang San answered without hesitation.

"Well, let's leave it at that for now. As for the essential issue of soul power transmission and storage in the soul guidance industry, in my opinion, it is closely related to materials science, and it's not something that can be solved by inspiration in a short time," Chen Feng sighed.

If these two problems can be solved, then the soul-guided industrial system can truly be established; but if they cannot be solved...

"Uncle Hao, have you ever heard of a kind of black oil? This black oil flows out from the ground. It is very viscous and has a pungent smell. It can also be ignited."

"Black oil?" Tang Hao thought carefully for a moment, then shook his head and said:

"I've never heard of it. I've been to many places, and I've read some records about strange places in the sect, but I've never seen anything like this or any related records."

"Alright." Chen Feng scratched his head regretfully.

He didn't know whether oil in this world had never been discovered or simply didn't exist, but either way, it was detrimental to the development of fossil fuel-related technologies.

However, the blacksmiths here seem to use charcoal furnaces. If there's coal, there's a chance that oil might also be present... Wait a minute, what kind of charcoal do the people here use? Chen Feng suddenly thought of an important question.

He immediately asked the question, and Tang Hao's answer made his heart sink:

"It's charcoal."

Oh no! Could there not even be coal here? If it's just that we haven't found any, that's fine, but if it doesn't exist... could it be that Douluo Star is too young and hasn't reached the age where fossil fuels can form yet? Chen Feng's eyebrows furrowed involuntarily.

He had originally planned that if soul guidance technology could be developed, he would develop it directly, because the energy utilization rate was relatively high, directly converting soul power into mechanical energy to do work, without any middlemen making a profit.

Earth's technological systems serve as an alternative, because that route requires energy to be converted several times before it can be used, which results in some energy loss, so it is temporarily considered a backup plan.

However, the conversation with Tang Hao pointed out a problem: it seems that there are no large-scale fossil energy resources in this world, at least not in the current human activity area. Xiao Wu next to him didn't say anything, which means that she had never seen anything like it either. This made the classic "boiling water" approach useless.

"Am I destined to follow the path of soul guidance to the bitter end?" Chen Feng muttered to himself.

He doesn't like situations where there's no other choice.

"What's wrong? Xiao Feng, is something bothering you?" Tang San asked, noticing his friend's worried expression.

Chen Feng couldn't bring himself to talk about fossil fuels, so he could only shake his head and say:

"It's still those two problems I mentioned earlier: the transfer and storage of soul power. I can't figure out where to start."

Tang San had no clue about either of these questions, so he patted Chen Feng on the shoulder and said:

"Let's put the problem aside for now. Didn't you say that these two problems depend on the development of materials science? Maybe when the team that collected the materials comes back, they will bring us some surprises? Also, among the metals that Dad mentioned, there might be materials with strong soul guidance properties."

“That’s right. We’ve already solved the problem of the soul power engine and its application today, which is a significant achievement. We can’t expect to become fat in one bite.” Chen Feng nodded.

Over the next few days, Chen Feng waited for his companions to return while also beginning his own cultivation.

No matter what you want to do, your own strength is of paramount importance. The ideal state is to talk about principles while having a firm grasp of physics.

Of course, a balance between work and rest is also necessary. Chen Feng's way of relaxing is to pet Tom and Jerry. He finds these two guys and pets them from head to toe, and immediately feels refreshed.

Furthermore, we can observe the changes that occur on Afei when the Cycle of Reincarnation is activated.

Because Tang San's Purple Demon Eye was a level higher than Chen Feng's, he was the one who mainly observed this change, and he did indeed gain something from it.

"Some blurry patterns?" Chen Feng was somewhat surprised; he hadn't expected his observation of A Fei to yield such a result.

“Yes, what I saw was that when you activated the Samsara Abyss, some illusory patterns appeared on A Fei’s body, but these patterns were not very clear. I may have to wait until my mental strength is stronger before I can see them clearly,” Tang San said.

"Okay, I understand, but even if you can't see it very clearly, it's best to write down the general shape," Chen Feng reminded him.

"Of course, I've already drawn everything I saw." Tang San handed over a small notebook.

Chen Feng took the notebook and glanced through it. His only thought was that the lines were really abstract, and he had no other thoughts.

It's true that there are disciplines on Earth related to shapes and lines, such as geometry, topology, and cryptography. Unfortunately, Chen Feng only knows the names of these disciplines; he knows nothing about their specific content, let alone conducts any research on them.

Therefore, when Chen Feng saw these lines, he knew that this was not a problem he could solve. He could only wait until Tang San's mental strength was stronger and see if he could discover any patterns in them.

As for himself, he could only choose to put the issue aside for the time being.

After Tang San and A Fei left, Chen Feng sat in the woods, preparing to continue his cultivation, when he saw a familiar figure walking over.

"Master!" Chen Feng stood up.

"Xiao Feng, how's your cultivation going?" Chen Xin asked with a smile.

"I just reached level 43 a couple of days ago."

"Hmm, not bad. You have a lot on your plate, so this cultivation speed is already quite good."

"Master, is there a level requirement for the Suifeng Sword Technique? Is my soul power level insufficient?"

“To use the complete Suifeng Sword Technique, a soul power of level forty-something is definitely not enough. But what I will teach you is only the essence of the Suifeng Sword Technique. What you need to do is to fully integrate it into your own sword technique, rather than just copying my sword technique,” ​​Chen Xin said with his hands behind his back.

Chen Feng understood. "So that's how it is. Please teach me, Master."

Chen Xin didn't say anything more and directly summoned his martial soul, the Seven Kill Sword.

This sword is like a crystal carving, with golden patterns on its blade, giving it a solemn and grand feel.

"The Suifeng Sword Technique is a sword technique I comprehended from the Seven Kill Sword when I broke through to level eighty. The so-called Suifeng means following the wind. It involves feeling the flow of the wind, controlling its changes, and making the sword move with the wind, thereby reaching the realm of controlling the wind with oneself and the sword with the wind. When the skill is mastered, the number of swords one can control is not only hundreds or thousands, but also tens of thousands." Chen Xin explained the Suifeng Sword Technique that he had comprehended.

Chen Feng blinked, a disrespectful thought suddenly forming in his mind:

Goodness, so you're the real "Happy Wind Man"? Oh wait, I should call you "Swift Wind Sword Master".

I'm going with the wind, right?

Chen Xin, unaware of what his disciple was thinking, asked:

"As far as I know, your martial soul can accommodate multiple attributes. Is the wind attribute one of them?"

"It should be. The Xun trigram symbolizes wind, wood, clouds, and rain, so absorbing a wind-attribute soul ring should be feasible," Chen Feng replied.

The Xun hexagram was the hexagram position he originally planned to repair, but because Dugu Bo was attracted by the Foundation Building Method, and with the help of the master, the Zhen and Dui hexagrams were put in a different order.

But as long as Chen Feng wants, the Xun trigram can be repaired at any time, because Tang San is here.

"In that case, you can choose to absorb a wind-attribute soul ring and then comprehend the essence of the Wind-Following Sword Technique from it. But I still maintain that you should not completely copy my path. You should integrate it into your own sword technique. I will demonstrate it for you now." After saying that, Chen Xin moved a certain distance away from Chen Feng, and then the sword in his hand began to move.

Chen Feng quickly focused his mind and watched his master's demonstration intently.

An unnamed wind rose from around Chen Xin, swirling the fallen leaves beneath his feet, which danced along with the Seven Kill Sword.

At first, Chen Feng didn't notice anything amiss, but he quickly realized something was wrong. He discovered that although his master wasn't making any attacking movements and the Seven Kill Sword was just being wielded, he felt a chill run down his spine.

Instinctively, he took a step back, and then saw that with the blowing of that invisible wind, the ground around Chen Xin had been covered with sword marks at some point.

"Holy crap, if I go there, won't I be torn to pieces?" Chen Feng gradually understood what was going on.
