Soul Power Engine
"Where should we start?" Tang Hao asked impatiently.
"Let's start with the Soul Bone and see if the Blue Silver Emperor can absorb it," Chen Feng said.
"What about the Soul Ring?"
"No rush, let's take it one step at a time, so as not to overdo it."
Seeing that Tang Hao was still somewhat anxious, Chen Feng sighed inwardly and said, "The Blue Silver Emperor hasn't been here for long, and its essence hasn't recovered much. If we were to infuse all the Soul Ring and Soul Bone into her at once, there might be some risks."
Hearing this, Tang Hao gradually calmed down.
He removed the Blue Silver Emperor Right Leg Bone from the Lead Box. "What do I need to do?"
"Hmm... let's put this Soul Bone together with the Blue Silver Emperor first, and see if she has the ability to absorb Soul Bone on her own," Chen Feng said after thinking for a moment.
Tang Hao did as instructed and placed the Soul Bone on the ground, gently pressing it against the Blue Silver Emperor.
The next second, a faint Blue and Gold light emanated from the Soul Bone, seeping into the branches and leaves of the Blue Silver Emperor.
"It should be absorbing, right? Has it been successful?" Tang Hao asked somewhat nervously.
"It is indeed absorbing, but the speed is really too slow." Chen Feng stroked his chin. "Xiao San, Xiao Wu, you two try using the Jade Rabbit Pounding Medicine to see if it can help the Blue Silver Emperor."
"Okay." Tang San immediately agreed and gently embraced Xiao Wu.
Two illusory images of Martial Soul emerged from their bodies. Then, the illusory image of Blue Silver Grass was swallowed by the illusory image of Soft Bone Rabbit. After chewing a few times, it turned into a stream of Life Force green energy and spewed onto the branches of the Blue Silver Emperor.
The Blue Silver Emperor trembled slightly, as if it could breathe, and completely absorbed the green energy into its body. The light from the Blue Silver Emperor Right Leg Bone also intensified, and the speed at which it seeped into the Blue Silver Emperor's branches and leaves increased visibly.
But this scene did not last long. After only about ten minutes, the Blue Silver Emperor Right Leg Bone returned to its original state, slowly seeping in again.
"I understand. The Blue Silver Emperor can absorb this Soul Bone that originated from her own body, but because her recovery is not yet complete and she doesn't have enough Life Force, the absorption speed is not fast," Chen Feng said.
Tang San continued, "My and Xiao Wu's Martial Soul Fusion Skill can provide Life Force, so under the impetus of this Life Force, my mother's absorption of the Soul Bone has accelerated considerably. However, since this Life Force is not something my mother herself possesses, this situation is only temporary."
"That should be it." Chen Feng nodded.
Ah Yin's current situation is actually a bit awkward. She needs strong Life Force to fully absorb her own Soul Bone in order to restore her original power.
However, if she doesn't restore her original power, she won't be able to fully absorb her own Soul Bone.
Karazhan from Karazhan is considered "graduating" in this context.
"It's alright, Xiao Wu and I can stay here. As long as we've rested, we'll use our Martial Soul Fusion Skill once. That way, Mom will recover sooner or later," Tang San said after consulting Xiao Wu.
"That's one way too. During the intervals between your Martial Soul Fusion Skill, Ah Yin can slowly absorb the power from the Soul Bone. As long as there's enough time, it can accumulate little by little. But that would be very tiring for you. How about this, once a week?" Tang Hao didn't quite agree with his son's idea and proposed a new solution.
"Dad, I'm fine..." Tang San wanted to say that he recovered quickly.
But Tang Hao waved his hand, "It's settled then. You should focus on your cultivation now. Once your cultivation levels are higher, the effect of your Martial Soul Fusion Skill will be even better. Ah Yin's recovery won't happen overnight."
"Well... alright." Tang San thought it made sense, so he didn't insist any further.
At this moment, Chen Feng made a suggestion, "This Soul Bone can't just be left out like this. I think it's better to bury it in the soil, preferably in Lead Box, leaving only a gap so that the Blue Silver Emperor's roots can get in."
Soul Bone naturally exude an aura, and the aura of Hundred Thousand Year Soul Bone is even more extraordinary. If it's not hidden properly, it could cause trouble if someone passes by and notices it.
"That makes sense." Tang Hao, reminded, immediately squatted down and started digging. To avoid damaging the roots of the Blue Silver Emperor, he didn't even use any tools.
"Dad, let me do the digging." With that, Tang San summoned the Blue Silver Grass and plunged it into the ground, quickly carving out a passage leading to the roots of the Blue Silver Emperor.
Tang Hao placed the Soul Bone into the Lead Box, leaving a gap, and then sent the Lead Box into the passage. Tang San then used Blue Silver Grass to restore the land.
After doing all this, Tang Hao walked around and nodded, saying, "When I came close to Ah Yin, I could still sense a trace of her aura, but I couldn't sense it anymore once I got a little further away. After Ah Yin absorbed the Soul Bone and slowly recovered, the fluctuations became even harder to detect due to the ebb and flow of energy. Not bad."
"I hope Mom recovers soon," Tang San wished.
Looking at the lush Blue Silver Emperor before him, Chen Feng asked, "By the way, are there any Foundation Establishment items for the Life Attribute?"
Tang San was taken aback for a moment, then said, "It seems not. I've never heard of such a thing being available on the market."
"What a pity, if we had some, we could have bought some and kept them here."
"It seems that only basic elements like wind, fire, water, and thunder have Foundation Establishment materials, while elements like life, death, and fate do not."
"Perhaps these attributes are more advanced and complex, which is why they cannot Foundation Establishment in nature," Chen Feng speculated.
After the matter of the Blue Silver Emperor came to an end, Chen Feng and the others began the next phase of their work, which was to try to replicate the power structure of the Music Box and find a way to increase its output.
The most essential requirement for this job is a suitable Carving Knife.
Therefore, Chen Feng sent Ning Rongrong back to the sect to see if there were any usable materials in the sect's treasury. However, before that, Tang Hao might also drop some materials.
"A material strong enough—" Tang Hao thought for a moment, "How about Deep Sea Sunken Silver?"
"Isn't that a huge anvil? Uncle Hao, do you have a way to separate it?" Chen Feng asked.
"There are also smaller pieces." After saying that, Tang Hao took out a sharp gray stone from his Storage Soul Tool.
"This is a scrap of silver I found when I discovered the Deep Sea Sunken Silver. Its shape is quite suitable if you need Carving Knife."
Tang San took the gray stone, examined it briefly, and nodded, saying, "It should be usable. Although Deep Sea Sunken Silver isn't the hardest of all metals, it should be fine for general carving work."
"Then what is the hardest metal?" Xiao Wu asked curiously.
"It is Cold Heart Iron Essence, but I've only ever heard of it. When I was traveling all over the continent back then, I never encountered this metal," Tang Hao said with some regret.
This metal, along with the Silver Mother from Deep Sea Sunken Silver, is also an essential material for making the Pear Blossom Needles of Torrential Rain, Tang San thought to himself.
"Perhaps Rongrong can give us a surprise. Hopefully, she can bring some good materials," Chen Feng said.
Tang San shook his head. "Rongrong doesn't even recognize metals, how would she tell which is good and which is bad?"
"Of course she can. The Seven Treasure Glazed Tile Pagoda's innate ability is appraisal, and this ability has been further enhanced after it was upgraded to the Nine Treasure Glazed Tile Pagoda. Although Rongrong doesn't recognize metals, she can distinguish the value of different metals."
"Is that so?" Tang San looked astonished.
Tang Hao nodded. "I've heard of that too. The Seven Treasure Glazed Tile Sect School's ability to appraise treasures played a significant role in its becoming the wealthiest sect on the continent. Back when the Clear Sky Sect hadn't gone into seclusion—never mind, let's not talk about that."
"Dad, when I become strong, I will definitely return to the sect." Tang San said earnestly.
Tang Hao patted his son's head and smiled, "Let's talk about it later."
Tang San didn't say anything more, picked up the sharp stone in his hand and began to replicate the power structure of the Music Box.
At first, the work did not go smoothly, and there were occasional mistakes in the drawings. However, after Tang San learned to use his Mental Power to assist in the drawing without a teacher, his drawing work never made any mistakes again.
Soon, a cylinder and rotor made of Star Soul Mithril appeared in front of them, with patterns engraved by Tang San on them.
According to more professional terminology from the Douluo Dalu 2 era, this pattern should be called Core Array.
"We also need something to hold the rotor in place, and it would be best to apply some lubricant to the contact surfaces between this thing and the rotor," Chen Feng suggested.
"That's easy." Under Tang Hao's guidance, Chen Feng's requirements were quickly met.
Immediately afterwards, Tang San assembled the three together and then infused them with Soul Power.
Almost simultaneously, the rotor inside the cylinder began to spin rapidly.
"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 use this to introduce a new concept called Soul Tool Performance, which is the ability of Soul Power to be transmitted through metal. The greater the loss during transmission, the worse the Soul Tool Performance Soul Tool Performance, and vice versa."
Tang San understood, "That means the metal used in the Music Box is inferior to Star Soul Mithril in terms of Soul Tool Performance, which is why there's such a big difference in their rotation speeds."
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 try channeling Soul Power into it and see if the rotor's speed changes."
Tang San handed the item in his hand to Tang Hao Tang Hao, who then channeled his Soul Power into it. 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 examined the wildly spinning metal structure before him, his mind filled with ideas. He gestured and said, "Xiao Feng, what do you think? If we put an arrow casket on this and add a metal baffle to the rotor, wouldn't it be able to fire Crossbow Bolt at an extremely high speed?"
Chen Feng smiled and said, "Why must we limit ourselves to Crossbow Bolt? We can directly make sharp metal rods and then cut several Blood Groove on them. This way, the metal rods can fit together very tightly, which is something Crossbow Bolt 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 Crossbow Bolt as you suggested, then even if the rotor rotates faster, the speed at which the Crossbow Bolt descends will not change, and the rate of fire will ultimately be limited. However, if we use a sharp metal rod with Blood Groove, we can compress it through a structure like a spring, which will greatly increase the speed of loading the bullet."
"There's no need to worry about it not being lethal enough. We can just 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. That way, once it enters the human body, the tip will explode directly into a flower-like shape. However, this will greatly reduce its penetrating power."
"Hiss~" Tang San gasped, momentarily unsure whether he or Chen Feng was a true member of the Tang Sect.
Oh no! I've been identified as an 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 just said, this thing still has room for improvement. If it continues to develop, it might be okay for Titled Douluo, but for Soul Master at lower levels...
"Using metal rods as projectiles alone isn't enough," Chen Feng continued. "We can work on the projectiles themselves, for example, by adding explosive materials and making the entire structure larger. This would significantly increase its power."
Tang Hao & Tang San: Please, have some decency.
But no matter how much the Tang father and son secretly complained, they couldn't stop Chen Feng from combining the power structure in front of him with Gunpowder.
It doesn't necessarily have to be Gunpowder. If better explosives are discovered in the future, or a suitable Core Array is obtained, then it can also be considered as a launcher.
Wait a minute, why did I suddenly think about weapons? I should have considered 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 Rotating Mechanism?" Tang San suggested.
"Or to put it more simply, how about Soul Power Engine?" Chen Feng asked.
"It feels pretty good." Tang San nodded in agreement.
