Chapter 789 Primordial Elixir
Nighttime.
Dugu Bo set up camp nearby, relying on his formidable presence to ensure that no reckless ten-thousand-year-old soul beasts dared to approach.
Meanwhile, Sun Ming used two ice mirrors to demonstrate to the two of them the light-transmitting effects of concave and convex lenses.
Concave lenses scatter light, while convex lenses concentrate it, but adjustments are needed in terms of position and thickness.
"In the academy, those who can't see distant objects are nearsighted, meaning the transparent layer at the pupil of their eyeball bulges outward, causing light to focus closer. Therefore, they need to wear concave lenses that can spread the light outward."
Sun Ming explained to the two, "Conversely, those who can't see nearby objects need to wear convex lenses, adjusting the imaging in the brain. These are my current observations and deductions."
"In other words, the human eye can see things because it contains a transparent organ similar to a concave lens, which is also why people can't stare at the sun for too long. The sun's light is too intense and can burn the cells and nerves inside the brain connected to the eyes."
Dugu Bo said, "I didn't expect the human eye to see things this way... But what does this have to do with Yan Yan's External Soul Bone? Is it that if she accidentally becomes nearsighted in the future, she can use it as glasses? That seems like a good idea."
"Grandpa!" Dugu Yan pouted, "I will never become nearsighted; it's such a hassle!"
Indeed, people who wear glasses all wish to take them off, but unfortunately, they can't because it would affect their daily lives and make it difficult to see things clearly, whether they're near or far.
"If you really become nearsighted, using it as glasses is quite useful. It prevents soul masters from having to use Soul Power to protect their glasses, lest they lose them in battle and become handicapped."
Sun Ming joked a little, then seriously said, "However, I have other thoughts about Yan Yan's thirty-six petal lotus. With the cooperation of Soul Power, it might be possible to harness the energy of sunlight. Let's discuss it tomorrow, as we need sunlight."
The next day.
The sun was shining brightly.
Sun Ming asked Dugu Yan to release the External Soul Bone, and then used his Soul Power to circulate over it. He also had Dugu Yan's Soul Power follow his across the petals, allowing the thirty-six petals to form an over three-meter-wide lotus suddenly.
Beneath the sun, they constantly adjusted the angle to focus the sunlight, eventually concentrating it to a single point.
Whoosh!
In an instant, a golden beam of light shot out from the center of the lotus petals, cutting through everything and carving a trench through the forest for thousands of meters.
Dugu Bo was greatly shocked, observing the line cut into the ground, which had penetrated a hundred meters deep into the earth!
Such penetrating power!
After a minute, Dugu Yan retracted the lotus crown, but it seemed that her Soul Power hadn't been significantly consumed.
How is this possible?!
Although there was no perceptible Soul Power fluctuation in the attack, Dugu Bo was sure he couldn't endure such an attack and would only be able to try his best to dodge it.
An attack that could severely threaten someone on the verge of becoming an ultimate Douluo was released so easily by a Soul Elder, and it seemed to consume hardly any energy!
"Are you surprised?" Sun Ming asked with a smile.
"Extremely!" Dugu Bo was at a loss for words, "Even an ultimate Douluo would find it hard to withstand such an attack. If it wasn't for the adjustments needed before launching, I'm afraid as long as it was aimed properly, not even an ultimate Douluo could escape it, given the speed of light..."
"A convex lens can concentrate light. This thirty-six-petal lotus External Soul Bone is made up of thirty-six convex lenses that can adjust size, thickness, and volume under the control of Soul Power. Adjusting and coordinating them can focus the sunlight into a point and shoot it out."
Sun Ming calmly analyzed, "The sun's light is gentle, but when concentrated to a point, it's incredibly powerful. I don't need to say more; it has already been demonstrated. Even the extreme of light-attribute martial spirits can't compare to the sun's brilliance."
"However, for Yan Yan to perform this attack without me, she first needs extremely strong control over her Soul Power. This is easily resolved, as I can teach her the method for Soul Power circulation; Soul Power and spiritual power can both reach the standard."
"Next, she must actively adjust the size, volume, and thickness of these thirty-six petals according to different lighting conditions to focus the light into a point."
"This requires a lot of experimentation, and—"
"Knowledge."
"For a soul master, knowledge is power."
"For example, for that attack earlier, Yan Yan only needs precise control over the External Soul Bone with Soul Power and spiritual power, plus corresponding knowledge. The energy is the sun in the sky, endless. Even in overcast weather, sunlight still penetrates the ground, as humans see things because there is light."
"Therefore, once she has mastered the necessary knowledge, she won't need to provide the energy herself."
"The only issue is that even with a soul bone, there's a limit to how much light it can withstand and can't be used for extended periods. With a twelve-thousand-year External Soul Bone, the limit is about a minute, but this duration will increase with the bone's age."
Dugu Yan, with her current abilities, couldn't release the full power of that light, but she remembered where the External Soul Bone was used. She felt that even if she couldn't adjust it at will, with practice, she should be able to skillfully release weaker light.
After a moment of reflection, Dugu Bo packed up and set off with the two to help Sun Ming search for his sixth soul ring.
Upon learning that Sun Ming wanted a dark attribute for his sixth soul ring, the Diamond Ape took the initiative to lead the way deeper into the Sunset Forest and found a relatively dark valley.
"This is the Ghost Valley in the Sunset Forest, the territory of the ghost monkeys. I know a hundred thousand-year-old ghost monkey there, who has been hesitating between transforming and overcoming tribulations, having reached the limit of experiencing heavenly tribulation."
The Diamond Ape sighed slightly, "Transforming carries too much risk. If discovered by a human Titled Douluo, it would be killed and its bone taken; overcoming tribulations is too deadly for the ghost monkey, with its dark attribute, to survive a lightning strike. That's why it has been putting it off."
"When it meets you, the king, I'm sure it will choose to follow you."
Subsequently, the Diamond Ape let out a cry that startled the entire Ghost Valley. All sizes of ghost monkeys, led by one that was entirely grey-black with a blue face and ten white crescent-shaped markings on its chest, rushed over.
A millennium ghost ape would grow one crescent-shaped mark on its chest, ten marks signify a hundred thousand years.
Clearly, this ghost ape was the hesitant hundred-thousand-year soul beast that the Diamond Ape had mentioned. Find the source of this chapter at M|V|L-EMPYR.
"Brother Diamond Ape, what wind blew you here?" the ghost monkey looked at the Diamond Ape, feeling something strange about it, especially why it was with a human?
The Titled Douluo beside was indeed unfathomable!
Sun Ming released his Mind Ape martial spirit, which startled the ghost monkey. After glancing at the Diamond Ape, it immediately understood something and said, "Greetings, King!"
Without further ado, it sacrificed itself directly.
The red hundred-thousand-year soul ring was slowly absorbed by Sun Ming within a minute, then the hundred-thousand-year ghost monkey leaped out from the soul ring, watching its former body's corpse dissipate.
For a ghost monkey, after death, its soul ring being absorbed causes the body to disperse, transforming into a kind of dark energy to nourish Ghost Valley.
Born in Ghost Valley, died in Ghost Valley, the cycle repeats, which is also the natural way.
Sun Ming took out a piece of black ginger and handed it to a nearby ninety-thousand-year-old ghost monkey, saying, "Eat this, it can accelerate your breakthrough to a hundred thousand years."
The ninety-thousand-year-old ghost monkey was extremely grateful, ingested it, causing its soul power to surge as the tenth crescent mark on its chest faintly emerged.
And the hundred-thousand-year ghost monkey that sacrificed itself to Sun Ming envied it, "If only I had eaten that ginger earlier, I might have become a hundred-thousand-year soul beast quicker... but still couldn't possibly overcome the heavenly tribulation, which targets soul beasts specifically."
The Diamond Ape chuckled, "Now it's good, we've left our origins behind, striving higher, and can enjoy the great path with the king."
Where it learned such vocabulary from is unknown.
After obtaining the sixth soul ring, Sun Ming's soul power increased to level sixty-four. The red on the fourth soul ring became more pronounced, the purple on the first ring deepened, and the second purple ring directly turned black.
The energy from high-level soul rings can also enhance lower-level soul rings.
The Earth Ape and Water Ape were extremely excited.
This was much easier than their arduous cultivation.
After obtaining the soul ring, Dugu Bo took Sun Ming and Dugu Yan back to the Ice-Fire Lake to stabilize soul power. Three days later, Sun Ming went to Xingdou Great Forest, back home to visit his parents, and set up a soul power circulation practice route for them before taking out the soul bone of the Diamond Ape tribe.
"Mom, here are the soul bones accumulated by the Diamond Ape tribe in the Sunset Forest, just right to have six pieces all over fifty thousand years, which your martial spirit, the Diamond Ape, can absorb."
Sun Ming said, "In the future, when I develop human soul bones, these can be replaced."
Yun Lan tenderly touched Sun Ming's head, "In your studies, don't push yourself too hard."
"I understand." Sun Ming knew, agreeing with his mother's words was the best result.
After Yun Lan absorbed the six soul bones, her physique greatly increased, and her soul power reached level seventy, reaching the threshold of Soul Sage, catching up with Sun Batian.
After going to the Ice-Fire Lake, Sun Ming sent home medicinal pills made from magical herbs, allowing Sun Batian to quickly break through to Soul Sage, and his mother also broke through to Soul Emperor.
Now that his mother's soul bones are complete, and her soul power has grown, she naturally reached level seventy.
"Xiao Ming, does Dad have a full set of soul bones?" Sun Batian asked expectantly.
"The soul bones of the Diamond Ape tribe can be assembled into three sets, but there aren't many from the millennium, and Diamond Ape's soul bones aren't quite suitable for you, as you're an iron rod martial spirit," Sun Ming reasoned logically, "It should be a full set of power type, like the Titan Giant Ape."
Sun Batian: "······"
Titan Giant Ape?
A full set too?
How is that even possible!
"But Dad, don't be jealous of Mom. I brought you a kind of pill mainly made from Primordial Herb, which after taking, can evolve your martial spirit, to make up for not bringing you a soul bone." Sun Ming took out a jade bottle, pouring out a pill with a flowing luminescence swirling on it······
