Heavenly Sword

Akiyama.

Guarded day and night by three thousand elite soldiers, it is one of the most important defensive points within Lingxiao City.

Unlike the military workshops in Lingxiao City, which were built inside the city and surrounded by layers of city walls, the Qiushan defense point, despite being surrounded by layers of barbed wire, could not ultimately match the defensive capabilities of the city walls. Over the past year or two, spies from various forces have ventured deep into Qiushan, trying to find out what was inside.

However, the matter of the Demon Realm Rift was a top secret. Apart from a dozen or so core members of the Gu Clan, such as Gu Chaoyang and Gu Chifeng, even Gu Changfeng, a member of the Gu Clan Lineage, was unaware of it.

The Demon Realm Rift only opens at fixed times. Occasionally, a few spies pay a huge price to venture deep into the Autumn Mountain Cave, but they can't uncover the true secrets inside. At best, they treat it as a military equipment storage point.

Furthermore, Gu Jinlai rarely come here more than a few times a year, which shows that the level of importance attached to this place is limited.

Over time, the number of scouts at this defensive point decreased significantly.

At this moment, outside the Qiushan Cave, in addition to Gu Chifeng, who was stationed in Lingxiao City, Gu Luochen, who was stationed in Baihe City, and Gu Xiliu, Gu Qingmei, Gu Yunxin, and others who had condensed the bodies of high-level demon gods had all arrived outside the cave and were guarding it heavily.

Having learned from their Gu Jinlai experience, they have used this cave as an armory, resulting in a vast collection of all sorts of equipment inside.

Among them, the close-in weapon system model, the Thunder Gatling gun model, the grenade launcher model, the missile model, and a Xuan Nu fighter jet model are particularly eye-catching.

As early as a year ago, in order to facilitate the entry and exit of large equipment such as radar stations, Gu Jinlai had already ordered the cave to be widened to more than ten meters. In addition, the cave has a huge interior space, so it is easy to accommodate a model of the Xuan Nu fighter jet.

Not just the Xuan Nu fighter jet.

Gu Jinlai at the velociraptor lying quietly beside him.

This time, he also plans to evolve this mount into a Tyrannosaurus Rex in one go.

If conditions permit...

Mechanical Tyrannosaurus Rex is also acceptable.

"Prioritize these things."

Eyes from both Gu Jinlai swept over each prop.

Have Gu Chifeng operate a close-in weapon system...

It is not necessarily possible that the flying sword of the Nascent Spirit Transformation stage cultivator could be intercepted and killed.

Two units should be enough.

Three units can ensure absolute safety.

If the quality isn't good enough, make up for it with quantity.

Therefore, close-in weapon systems (CIWS) are the top priority for Gongling going forward.

"Spirit Transformation cultivator can be intercepted by close-in weapon systems, but Primordial Spirit True Lord ..."

After a moment's thought, Gu Jinlai said, "They cultivate their Primordial Spirit and use it to control their swords. This makes them faster and allows them to carry True Qi, making them even more lethal. Unless we use several, or even ten, close-in weapon systems to form a dense barrage, it will be difficult to stop the flying swords of Primordial Spirit True Lord. Moreover, even if they can stop it once, they can stop it two or three times."

The number of bullets fired by a close-in weapon system (CIWS) every second is astronomical.

The reason why close-in weapon systems are so effective right now is because they don't understand this kind of killing Spirit Artifact.

However, as more and more scouts gather, the drawback of close-in weapon systems being rendered useless once their ammunition runs out will soon become apparent.

At that time, the Primordial Spirit True Lord only needs to fly around a thousand meters away on his sword a few times to exhaust the bullets of the close-in weapon system and then eliminate this terrifying source of firepower.

Therefore, he must have the means to threaten, or even kill, the Primordial Spirit True Lord.

"Missiles are the most important thing."

The gazes of people from Gu Jinlai shifted from the thirty close-in weapon system models to the fifty Sky Arrow missile models.

This is a missile with a wingspan of 1.5 meters and a length of 3 meters.

Compared to the flying swords of Spirit Transformation cultivators, it is a colossal object.

Moreover, the design drawings provided by Blue Star were so rough that he could hardly understand them.

If we're really talking about spiritual connection...

We have no choice but to force a spiritual connection.

Based on the hundreds of Demonic Spirit that emerged from the last opening of the Demon Realm Rift, if he were to forcefully activate the Heavenly Arrow Missiles using the method of spirit sharing, he would be lucky to be able to create two or three.

At that time, the entire Spirit Project involving close-in weapon systems, Swift Dragons, and Mystic Maidens will be ruined.

"Mystic Maiden Fighter..."

From Gu Jinlai taken a look at the enormous size of this fighter jet.

Well, even if he injects all the spiritual energy extracted from hundreds of Demonic Spirit into the Xuan Nu fighter jet, he can only obtain a third of the spiritual energy at most.

Therefore, he directly abandoned the plan for the Spirit Maiden Fighter during this Demon Realm Rift.

"Then, we'll use two Heavenly Arrow missiles. When we face the Purgatory Sect Primordial Spirit True Lord of the Purgatory Sect in the future, we can shoot one down to prove that we have the ability to kill Primordial Spirit True Lord. We can keep one as a deterrent. This should bring us a long period of peace. I just don't know if we can hold out until the next time the Demon Realm Rift opens."

Gu Jinlai, let's turn our attention to the Tianjian missile.

Honestly.

Could this missile kill the Primordial Spirit True Lord...?

He wasn't very confident.

After all, the Primordial Spirit True Lord is essentially a sky combat platform, with plenty of ways to intercept and kill missiles.

Unless...

"I can unleash the Heavenly Sword Missile with the Spirit."

This Gu Jinlai.

The Tianjian missile is a high-speed, short-range missile carried by the Xuan Nu fighter jet.

Using nuclear explosions to generate power to propel missiles at hypersonic speeds to strike targets.

According to the missile's design, it can reach one-tenth the speed of light in a space environment.

As for the interior of the atmosphere...

The figures may vary depending on the materials, design, and power output.

"Using nuclear explosions to generate power... then give me a design blueprint for a nuclear pulse thruster."

Gu Jinlai muttered something under his breath.

He carefully recalled the fantastical missile data in his mind.

Thinking and thinking...

He suddenly realized that, aside from the nuclear pulse thruster, a major factor, the missile's other data was quite accurate.

It's like a fighter jet.

Putting the engine aside, its exterior and interior are quite attractive.

As for the engine issue...

"The Eternal Furnace within my body can absorb solar radiation to stimulate the hydrogen elements in my body to generate deuterium and superdeuterium, and then let the two fuse to release energy... This seems to be... the prototype of a nuclear fusion engine? And as my Eternal Furnace has reached a minor level of mastery and developed transfer and transformation properties, then..."

Gu Jinlai, attention has been drawn to the "Sky Sword" missile model, of which only three were ever produced.

"Is it possible for me to use the power of the Eternal Furnace through the shared spirit, transferring its transfer properties into the 'Heavenly Sword' missile, and using it as a nuclear pulse engine to launch it, just like Spirit Transformation cultivator wielding a flying sword... to blast away the opponent?"

Thinking of this, his eyes gradually brightened.

The Spirit Realm can only be controlled at close range!?

Don't forget.

When the Great Sun Ninefold Refinement Visualization Method is perfected, it gives rise to the characteristic of manifesting the True Spirit.

He can manifest his True Spirit and attach it to the Heavenly Sword missile, then activate the power transferred from the Eternal Furnace into the missile. After detonating this power, he gains unparalleled acceleration, and like Yin Spirit wielding a sword, he controls the missile with his True Spirit, blasting the target to pieces in one fell swoop.

Feasible!

Absolutely feasible!

The speed of the missile will then depend entirely on the power of its eternal furnace.

The higher the power of the eternal furnace, the higher the speed at which the missile explodes.

Furthermore, the power of the polymerization of deuterium and superdeuterium can also be released in an uncontrolled manner, forming a small-scale nuclear explosion to destroy the target.

In this way...

A nuclear-powered hypersonic missile carrying a nuclear warhead has been born!

"Perfect!"

He exclaimed in sincere admiration Gu Jinlai.

He couldn't wait to contact the Blue Star again and ask them to provide the structural design drawings of the nuclear warhead.

"Buzz!"

At this moment, the ripples emanating from the cave were growing stronger and stronger, and the surrounding space was rapidly distorting.

For a moment, Gu Jinlai had to calm down.

"This time, I was well prepared. During the time I was stationed in Baihe City, I made a special trip to the county towns below and wiped out all the Red Name I could find, accumulating nine cleared lights."

Nine beams of clear light, fifty percent more than the six beams last time.

With everything in place, all that remains is to wait for the Demon Realm Rift to fully open.

Two days later, the intensity of the spatial ripples increased dramatically. At its core, cracks appeared, and illusory figures emerged from them.

"It's finally here."

Gu Jinlai have breathed a sigh of relief.

He was worried that the Demonic Spirit, having been terrified of him last time, wouldn't come back.

The Demonic Spirit that burst out of the cracks charged bravely and fearlessly toward the Gu Jinlai, without hesitation throughout the entire process.

However, as one approaches the Gu Jinlai, a blazing, dazzling golden light emanates...

Just like frying an egg.

Crack an egg into the chili oil, and the egg will quickly cook, releasing a rich aroma...

Spiritual fluctuations.

These spiritual insights, extracted from the Gu Jinlai, were then unhesitatingly poured into the Sky Sword missile model standing to the side.

Upon receiving spiritual infusion, the Heavenly Sword missile, which was originally a model structure, underwent subtle changes, growing into the "Heavenly Sword" missile envisioned from Gu Jinlai, carried by the Mysterious Maiden fighter jet.

Although the information provided by Blue Star is limited, the sheer amount of pure spiritual energy gained from slaying Demonic Spirit Gu Jinlai is undeniable.

Furthermore, he solved the most important part of the missile—the engine—using the rotational properties of the Eternal Furnace, so that with only a dozen or so Demonic Spirit, the Sky Sword missile already had a metallic sheen with a futuristic technological feel.

After the spiritual energy extracted from about twenty Demonic Spirit was unleashed, the missile's surface shimmered with light, clearly indicating that it was about to complete its transformation.

"Good!"

Seeing this scene, Gu Jinlai have felt genuine joy.

Without hesitation, he took out a second Sky Sword missile model and continued to communicate with the spirit...

The process was extremely fast.

Under the blazing sun, the Demonic Spirit that rushed out were almost all killed, completely unable to do anything to Gu Jinlai was even more powerful than before.

Before long, all three Sky Sword missiles were fully imbued with spirit, their surfaces shimmering with light, exuding an aura of science fiction and fantasy.

"Why didn't I think of using load-bearing characteristics as the engine for the Sky Sword missile sooner?"

Gu Jinlai, there have been many regrets.

If he had figured this out earlier, why would he have bothered producing the Tianjian missile? Wouldn't it have been better to have thirty or fifty Tianjian missiles?

The feeling of regret lasted only a moment before he dismissed it.

Its load-bearing characteristics have only been developed for less than a month. What would be the point of thinking about it earlier?

He focused his mind again on using the experience monsters that had escaped from the rift in the Demon Realm to upgrade the melee defense cannon model.
