Chapter 141: Chapter 138 Heavenly Sword
Qiushan Mountain.
Guarded day and night by three thousand elite, it was one of the most important defense points within the territory of Lingxiao City.
Unlike the military workshops established within Lingxiao City, wrapped by layers upon layers of city walls, the defense point of Qiushan Mountain, although surrounded by loops of barbed wire, ultimately could not compare to the defensive power of city walls. Within a year or two, many spies from various forces infiltrated Qiushan Mountain, trying to uncover exactly what was inside.
However, the matter of the Demon Realm Rift was top secret. Apart from Gu Chaoyang, Gu Chifeng, and a handful of other core members of the Gu family, even Gu Changfeng, the head of the Gu family, was unaware.
And the Demon Realm Rift would only open at fixed times; occasionally, a few spies paid a great price to delve deep into Qiushan Cave and still could not grasp the true secrets within, at most considering it a military armament storage point.
Added to that, Gu Jinlai rarely visited this place, showing the limited level of importance placed on it.
As time went by, the number of spies at this defense point significantly decreased.
...
At this moment, outside Qiushan Cave, apart from Gu Chifeng who was stationed in Lingxiao City, Gu Luochen who was in Baihe City, and Gu Xiliu, others who had conjured the body of an Upper Demon God like Gu Qingmei and Gu Yunxin had already arrived outside the cave and were guarding it heavily.
With the experience from last time, Gu Jinlai directly used the cave as an armory storage room, such that inside the cave, there were countless types of devices.
Among them, the models of the Short Range Defense Cannon, Thunder Gatling Gun, Artillery, Missile, and the model of Fighting Machine Xuan Nu, were especially conspicuous.
As early as a year ago, to facilitate the entry and exit of large machinery like radar stations, Gu Jinlai had ordered the expansion of the cave to over ten meters in width, and with the cavern’s vast internal space, accommodating a model of the Fighting Machine Xuan Nu was effortless.
Not just the Fighting Machine Xuan Nu.
Gu Jinlai glanced at the Swift Dragon lying quietly beside him.
This time, he also planned to cultivate and evolve this mount into a T-Rex in one go.
If conditions permitted...
A Mechanical Tyrannosaurus was not out of the question either.
...
"These things need to be prioritized," Gu Jinlai said.
His gaze swept over each item.
Having Gu Chifeng operate a Short Range Defense Cannon...
Couldn’t necessarily intercept the flying sword assassination by a Divinity Transformation Cultivator.
Two of them might just about do it.
Three would even more so ensure absolute safety.
If quality is insufficient, make up with quantity.
Thus, the Short Range Defense Cannon is the top priority for Co-spirit Technique in the following period.
"Divinity Transformation Cultivators could rely on Short Range Defense Cannon for interception, but Primordial Spirit Monarchs..."
Gu Jinlai pondered briefly, "Once they cultivate their Primordial Spirit and control their swords with it, their speed is faster, and they can even wrap True Qi around it, increasing the lethality by a fraction. Unless using several cannons, even up to ten Short Range Defense Cannons to create a dense barrage net, otherwise it will be hard to block the sword strikes from a Primordial Spirit Monarch. Moreover, if it can block once, can it block a second or third time?"
The amount of bullets a Short Range Defense Cannon pours out every second is astronomical.
The current success of Short Range Defense Cannon is because they are not familiar with this Slaughter Spirit Artifact.
But as more and more spies investigate, the flaw of Short Range Defense Cannon becoming useless once its bullets are exhausted will soon be exposed.
By then, a Primordial Spirit Monarch would only need to control their sword and stroll around a thousand meters away, depleting the bullets of the Short Range Defense Cannon, and they would be able to remove this fearsome point of firepower.
Therefore, he must have means that can threaten, even kill a Primordial Spirit Monarch.
"Missiles are the true priority," Gu Jinlai stated.
His gaze moved from the thirty Short Range Defense Cannon models to rest upon the fifty models of Sky Arrow Missiles.
These missiles, with a wingspan of one and a half meters and a length of three meters, were huge compared to the flying swords of Divinity Transformation Cultivators.
Moreover, the design diagrams provided by Blue Star were extremely crude; he could hardly understand them.
If he were to Co-spirit with them...
He would have to forcibly do so.
Based on the hundreds of Demon Spirits that emerged during the opening of the last Demon Realm Rift, if he were to use the forced Co-spirit Technique to initiate the Sky Arrow Missiles, managing to co-spirit two or three would be good enough.
By then, the Co-spirit plans for the Short Range Defense Cannon, Swift Dragon, and Fighting Machine Xuan Nu would all go down the drain.
"The Fighting Machine Xuan Nu..."
Gu Jinlai glanced at the massive size of this type of fighter.
Well, even if he extracted all spiritual traits from the bodies of over a hundred Demon Spirits and injected them into the Fighting Machine Xuan Nu, at most, he would only be able to Co-spirit a third of it.
Therefore, for this Demon Realm Rift, he simply abandoned the plan to Co-spirit with the Fighting Machine Xuan Nu.
"Then, Co-spirit two Sky Arrow Missiles. That way, in the future when facing the Divinity Transformation Monarchs of Purgatory Sect, firing off one might prove my own ability to assassinate a Primordial Spirit Monarch. Retaining another as deterrence should grant a long period of peace. The question is whether it could last until the next Demon Realm Rift." Gu Jinlai mused, shifting his gaze to the Sky Arrow Missiles.
To be honest,
Whether these missiles could kill a Primordial Spirit Monarch...
He wasn’t very confident.
After all, a Primordial Spirit Monarch was essentially equivalent to a sky combat platform and had plenty of means to intercept a missile strike.
Unless...
"I could co-spirit the Heavenly Sword Missile," Gu Jinlai voiced.
The Heavenly Sword Missile was a high-speed, close-range missile equipped by the Fighting Machine Xuan Nu.
Using the power generated from a nuclear explosion to propel the missile at ultra-high speeds to strike the target.
According to the missile design, in a space environment, it could reach one-tenth the speed of light.
As for within the atmosphere...
It would vary depending on the materials, design, and power output data.
"Using nuclear explosions for propulsion... You might as well give me the design diagram for a nuclear pulse propulsion system,"
Gu Jinlai muttered to himself.
He carefully recalled the fantastical missile data in his mind.
As he pondered...
Suddenly, he felt that, aside from the key factor of nuclear pulse propulsion, the other data about the missile was actually quite precise.
It was like a fighter jet.
If you disregard the engine, the exterior and interior design is still quite appealing.
As for the engine problem...
"My Eternal Furnace can stimulate the hydrogen elements in my body with solar radiation to derive heavy hydrogen and super heavy hydrogen, and then allow them to fuse and release energy... This seems... like the prototype of a nuclear fusion engine? As my Eternal Furnace reaches Small Achievement and develops the transmission trait, then..."
Gu Jinlai’s gaze fell on the model of the "Heavenly Sword" missile, of which only three had been produced.
"Is there a possibility that I could use Co-spirit to channel the power of the Eternal Furnace into the ’Heavenly Sword’ missile through its transmission characteristic, acting as a nuclear pulse engine to shoot this missile, much like a Divinity Transformation Cultivator controls a flying sword... allowing it to annihilate the opponent?"
With this thought, his eyes gradually brightened.
Co-spirit state can only control at short range!?
Don’t forget.
When the Grand Sun Nine Refinement Visualization Method reached Perfection, it developed the True Spirit Manifestation trait.
He could use True Spirit Manifestation to attach to the Heavenly Sword missile, then trigger the power of the Eternal Furnace transferred into the missile, ignite these powers to obtain an unparalleled acceleration, like Yin God Sword control, True Spirit controlling the missile, in one fell swoop annihilating the target.
Feasible!
Perfectly feasible!
By then, the missile’s speed would entirely depend on the power of his Eternal Furnace.
The higher the power of the Eternal Furnace, the higher the missile’s explosive speed.
In addition, the fusion power of heavy hydrogen and super heavy hydrogen could also be released in a loss of control manner, forming a small-scale nuclear explosion to annihilate the target.
In this way...
A nuclear-powered supersonic missile with a nuclear warhead was born!
"Perfect!"
Gu Jinlai sincerely praised.
He could hardly wait to contact Blue Star again to get the structural design diagram for the nuclear warhead.
"Humming!"
At this moment, the ripple emanating from the cave was growing stronger, and the space around was quickly distorting.
For a while, Gu Jinlai had to calm down.
"This time, I was well prepared. During the time I stationed Baihe City, I specifically went down to the county town a few times and cleared out all Red names I could find. The accumulated Qingguang reached nine Dao."
Nine Dao of Qingguang, fifty percent more than the last six Dao.
Everything was ready, and now, he was just waiting for the Demon Realm Rift to fully open.
...
Two days later, the intensity of the spatial ripples surged dramatically, and at their core, a rift emerged, with somewhat illusory figures appearing one after another from within.
"They’re finally here."
Gu Jinlai let out a sigh of relief, feeling relieved.
He was worried that the Demon Spirits were scared off by his previous slaughter and would not come again.
The Demon Spirits, fearlessly charging out of the rift, were unwavering in their assault on Gu Jinlai.
However, as soon as they approached Gu Jinlai, brilliant golden light radiated...
Just like frying an egg.
Crack an egg into hot oil, watch it cook quickly, and the rich aroma fills the air...
Spiritual fluctuations.
Gu Jinlai extracted the essence of these spirits and, without any hesitation, injected it into the Heavenly Sword missile model to the side.
With spirit infusion, the Heavenly Sword missile model, which was originally just a structure, underwent subtle changes internally, growing towards the "Heavenly Sword" missile as imagined by Gu Jinlai, equipped on the Xuan Nu fighting machine.
Although the data provided by Blue Star was scarce, it couldn’t match the pure spirit that Gu Jinlai obtained after killing Demon Spirits.
Plus, the most important part of the missile—the engine—was solved by the transmission trait of his Eternal Furnace. Within just a dozen or so Demon Spirits, the Heavenly Sword missile was already filled with a futuristic metallic luster.
After another twenty or so Demon Spirits’ spirits were smashed into it, the surface of this missile shimmered with brilliant light, already on the verge of a full transformation.
"Good!"
Seeing this scene, Gu Jinlai felt genuine joy.
Without hesitation, he took the second model of the Heavenly Sword missile and continued the Co-spirit process...
The process was extremely fast.
Under the Great Sun Brilliance, the Demon Spirits charging out were almost one to one—delivered as they came, completely unable to give the now even stronger Gu Jinlai any trouble.
In no time, all three Heavenly Sword missiles were Co-spirited, their surfaces shimmering with light, exemplifying both science fiction and fantasy to the fullest on these missiles.
"Why didn’t I think earlier that I could use the transmission trait as the engine for the Heavenly Sword missile?"
Gu Jinlai felt some regret.
If he had realized this earlier, why would he bother producing Sky Arrow missiles? Wouldn’t it be better to arrange thirty or fifty Heavenly Sword missiles?
The emotion of regret only lasted for a moment before he shook it off.
The transmission trait had only just evolved less than a month ago; how significant would it have been to think of it earlier?
Regathering his focus, he once again concentrated on using these Experience Monsters emerging from the Demon Realm Rift to upgrade the model of the Short Range Defense Cannon.
