The Void Inscription Array's cost-effectiveness isn't high.
At this moment, seeing Su Yu display such a technique, Kong Deming and Mirror Hongchen did not think Su Yu was just showing off.
However, they were indeed puzzled.
Soon, Su Yu resolved the doubts in their hearts.
Lacking the constraints of Rare Metals means that the flow rate and volume of each Soul Power circuit's diversion must be entirely controlled by the Soul Master.
But simultaneously, it also means saving on inscriptions on Rare Metals.
As long as one is familiar enough with the Array, it can theoretically be constructed instantaneously.
Su Yu took about a second to build the Array, his face slightly pale.
The moment the Array was inscribed, it emitted a radiant light.
Su Yu channeled his Spiritual Power with full force, maintaining the Array's operation to its maximum.
Subsequently, the Array was integrated into the Blue Silver Grass.
"It's been enhanced onto the Martial Soul!"
Can the Core Array inscribed in Soul-guiding Device production be used this way?
Kong Deming and Mirror Hongchen, the two Soul-guiding Device authorities, were greatly shocked!
Upon careful thought, it seemed there wasn't a problem...
...
A terrifying rumbling sound erupted.
On the stage, debris flew, mixed with fragments of Blue Silver Grass.
The center of the explosion turned into ruins, with smoke and dust permeating the air.
Mirror Hongchen and Kong Deming stared at the ruins.
Just now, Mirror Hongchen was stunned by Su Yu's actions and forgot to rescue for a moment. However, as a Ninth-Level Soul Guide, his Spiritual Power was also remarkable. Amidst the chaotic energy ruins, he sensed a presence of Life Force, which allowed him to breathe a sigh of relief.
The smoke and dust dissipated.
"This is..."
Seeing the scene on the battlefield, the corners of Mirror Hongchen and Kong Deming's mouths twitched.
The Blue Silver Grass was almost blown away entirely.
Even with the enhancement of the Core Array and Su Yu's precise construction, achieving maximum protection, it still couldn't withstand the strongest strike from the two High-Tier Soul Sect Martial Soul Fusion Skills.
However, it did negate most of the damage from this strike.
What ultimately protected Su Yu was those layers of Defensive Soul-guiding Devices.
That's right, still Soul-guiding Devices.
Su Yu himself was also a Soul Guide.
At the last moment, he activated his Defensive Soul-guiding Device.
Using the same shock-absorbing principle, layer upon layer of metal construction to minimize the attack's intensity.
The attack, which had already been mostly nullified by the Blue Silver Grass, was blocked by this Soul-guiding Device.
This Soul-guiding Device was not a Second-level one.
It was a Third-level Soul-guiding Device!
Moreover, it was a pinnacle work of Third-level Soul-guiding Devices.
Having mastered designs of numerous Level 1 and Level 2 Soul-guiding Devices, Su Yu naturally reached Third-level Soul Guide status.
He even used his spare time to devise designs for Soul-guiding Device production.
This Defensive Soul-guiding Device is his creation.
The production technique was entirely at the peak level of a Third-level Soul Guide, combined with its construction principles, this Soul-guiding Device's defensive power reached the level of a Fifth-level Defensive Soul-guiding Device!
The Soul-guiding Devices of Douluo Continent have not yet begun to delve into construction aspects.
There is minimal research on the internal mechanics.
The research taken to the extreme, no less, belongs to the Tang Sect's hidden weapons.
Su Yu utilized Soul-guiding Device technology, combined with mechanical structures, to create this Defensive Soul-guiding Device.
Pieces of the metal shell fell to the ground.
Kong Deming and Mirror Hongchen were speechlessly stunned.
The impressive technology used in the Soul-guiding Device was no longer visible, as it was almost entirely destroyed and, without careful study, it's difficult to ascertain.
However, they could recognize the metal used to create the Soul-guiding Device.
"This is damn Forbidden Demon Crystal, and Refined Gold and Black Steel!"
The Forbidden Demon Crystal, capable of weakening the damage from Soul Power and other energy attacks, holds its defenses remarkably.
Refined Gold and Black Steel are extremely rare Rare Metals, ranked among the hardest metals on the Douluo Continent.
These Rare Metals could even be used to produce Sixth-level Soul-guiding Devices!
It could be said that while Su Yu's Soul-guiding Device's technology is certainly impressive, most of its defensive power was essentially acquired through spending on Rare Metals!
His pinnacle technology of a Third-level Soul Guide, combined with the principles of mechanical construction, could at most reach Fourth-level in defensive power.
Yet, he forcefully upgraded it with Rare Metals to Fifth-level!
"Where did he get so many Rare Metals?"
As a Core Disciple, Su Yu does have a quota for Rare Metal distribution. Even if his status as Kong Deming's disciple further elevated his top-tier Core Disciple treatment double-fold, it is still limited.
But the crux of the matter is, Kong Deming knows that the tasks he assigned inherently consume a large amount of Rare Metals!
And in such circumstances, Su Yu actually had enough surplus to exchange for so many Forbidden Demon Crystals and Refined Gold and Black Steel?
It's simply outrageous!
On the stage, Su Yu moved.
The last of Red Dust Attachment's Soul Power was depleted, a flash of light shimmered, and the Three-legged Red Golden Toad vanished, revealing Xiao Hongchen and Meng Hongchen.
"Blue Silver Bursting Spear!"
"Art of Lifespring Cuttings!"
With their Soul Power exhausted, the brother and sister had no resistance before Su Yu and could only be blown off the stage.
Su Yu, victory!
Meng Hongchen, having overexerted herself, suffered a Martial Soul backlash and lost consciousness.
Xiao Hongchen opened his eyes into a slit, glanced around, and then closed his eyes, seemingly passing out as well.
"Meng!"
Mirror Hongchen hurriedly stepped forward, intending to check on Meng Hongchen's condition.
"Wait a moment!"
Su Yu walked to the siblings and first removed the Blue Silver Grass branches from their bodies.
Mirror Hongchen took out an Elixir and fed it to Meng Hongchen, using Soul Power to regulate the toxins within her body.
Vermilion-eyed Ice Toad, while possessing terrifying toxins, akin to the Green Phosphorus Snake and Evil Fire Phoenix as Martial Souls, also poses a risk of backlash to its host.
Fortunately, it wasn't a backlash caused by improper cultivation, and Meng Hongchen's condition quickly stabilized.
Su Yu also gave Meng Hongchen a bit of healing.
"First Soul Skill, Star Spirit Power!"
"Second Soul Skill, Purple Moon Purification!"
"Your Soul Skills can be used on others?" Mirror Hongchen was stunned, looking at Su Yu in surprise.
Su Yu was at a loss for words, unsure how to answer this question.
Mirror Hongchen also realized this and changed the subject, complimenting Su Yu, "I must say, your performance in this battle was truly brilliant!"
In the recent battle, he learned a lot.
Especially, that the Core Array of a Soul-guiding Device can be directly applied to the Martial Soul!
This insight sparked a torrent of inspiration for Mirror Hongchen.
...
"Xiaoyu, did you make this Soul-guiding Device yourself?"
Kong Deming was holding Su Yu's severely damaged Defensive Soul-guiding Device.
"Yes, teacher," Su Yu answered.
Kong Deming admired its ingenious structure, and seeing this, Su Yu took the opportunity to share his thought process.
"I heard of a faction called Tang Sect, known for their hidden weapons.
These require no Soul Power, yet can unleash terrifying destructive power.
Even the top-tier hidden weapons can threaten a Titled Douluo!
Through much contemplation, I could only deduce that the immense destructive power of the hidden weapons must be achieved through the construction between parts.
The construction method is so incredible, so I thought of incorporating it into Soul-guiding Devices.
Thus, this creation was born."
"My Soul-guiding Device is just an initial application of the construction method, and the effect is already evident.
Teacher, if Tang Sect's hidden weapons are as fearsome as rumored, their construction principles must be profound!
Using these principles in Soul-guiding Devices, the effects would absolutely be terrifying!"
