An invasion from the Abyss? I, a demonic cultivator, laughed.

Chapter 279 Heavenly Strike Divine Light
"No."

Almost the instant Aurora asked the question, Chu Xiu gave his answer.

"Huh?" Aurora seemed surprised that Chu Xiu answered so quickly.

“If a Blood Demon were to infiltrate disguised as an ordinary person, I would definitely discover it,” Chu Xiu said.

"That was not what I meant."

"There's nothing unusual about the people here."

Before Aurora could finish speaking, Chu Xiu interrupted her, looking at the blonde girl in front of him and saying calmly, "Let's hurry up and refine as many weapons as possible before the Blood Demon launches the final battle."

"what"

Aurora was somewhat disappointed, but still nodded and said, "Okay."

Although she was somewhat disappointed, Chu Xiu's answer seemed to put her mind at ease. Perhaps she felt that if even Chu Xiu hadn't noticed anything unusual, then she must have just been overthinking things.

Next, the two devoted themselves to the forging of electromagnetic guns. They spent a day and a half forging all the electromagnetic guns with the raw materials prepared in advance, totaling eighty-seven guns.

After another day, Chu Xiu forged more than two hundred high-pressure flamethrower cannons. With his superb skills, these cannons could spew flames up to three hundred meters high. When given to awakened individuals, they could serve as a good short-range air defense measure.

At the same time, fifty of them served as automatic turrets, blocking the base's path to the Titan Machine. Any enemy that passed by would be burned by hellfire.

Now, the large amount of fuel that Chu Xiu brought back could finally be put to good use.

He spent another half a day roughly reinforcing each of the remaining thousand or so cannons of the Titan Machine, further improving their durability and increasing their normal rate of fire by at least 30%.

This continuous refining process exhausted Chu Xiu, but it also resulted in a qualitative improvement in the firepower delivery of the Titan Machine.

Meanwhile, the factory was operating at full capacity, urgently producing a large number of metal shells, enough to meet the needs of the electromagnetic railgun.

"With this newly enhanced war machine, it should be able to withstand an attack for one to two hours without any problem."

"Especially when a foreign civilization does not allow subjective intervention in the spark of civilization."

"The only remaining question is whether the enemy will take the bait."

Chu Xiu let out a long breath and looked into the distance, where the sun was slowly rising.

After three days of refining, this is the fourth day of the trial.

In the past few days, the Blood Demon's army has been launching continuous attacks, but the Blood Sea is still far from arriving. As Chu Xiu guessed, the Blood Sea will only spread to the vicinity of the base city in the last few days.

Without the support of the Blood Sea, the continuous attacks of these low-level creatures were stopped almost without any losses by the Blood Demon Avatar and the Ghost Legion, which greatly preserved the number of shells in the base.

Of course, the price was the consumption of about three percent of the Heavenly Dragon Golden Pill's energy.

There was nothing that could be done about it. Three consecutive days of protracted fighting had taken a huge toll on energy, and Chu Xiu alone was simply not enough to sustain it.

Especially since Chu Xiu needed to conserve his strength.

In the past few days of battle, only two high-ranking ghost generals of the ghost army have fought, serving only to command the entire army and reduce losses. The Blood Demon Avatar has also only used two-thirds of its strength.

The combination of the two should mislead the opponent into thinking that they are a [Summoner] class, thus making it more likely that the opponent will carry out a decapitation strike against their true form.

"I just don't know when the other side will launch their final offensive."

Chu Xiu gazed at the seemingly endless, ever-surging army of blood demons in the distance and fell into deep thought.

The number of alien civilizations that have descended has reached a full ten.

This is a very unstable number; greed, suspicion, exploitation, and all sorts of evil thoughts will arise one after another.

However, if the five new civilization envoys arrive tomorrow, the rewards will be reduced by a third, which inevitably raises some concerns.

"Now all I have to do is wait patiently," Chu Xiu thought to himself.

At that moment, Aurora came to his side: "Mr. Chu."

"Is there anything else?" Chu Xiu asked.

Aurora said, "Mr. Chu, are you feeling tired? With a great battle imminent, it's really embarrassing to trouble you like this."

Chu Xiu said, "There's no need for such formalities. We Awakened Ones have strong spirits. Even if we refine without sleep for a month, it won't be a big problem. It will just consume some energy. We are already on the same side, so you don't need to be so polite."

Upon hearing this, Aurora breathed a sigh of relief and said, "In that case, I have another matter I would like to ask for your assistance, sir."

"Oh?" Chu Xiu was somewhat surprised. "Is there anything else?"

He felt he had done almost everything he could.

Aurora asked, "What do you think of the power of our base's Titan machines, sir?"

Chu Xiu thought for a moment and said, "The firepower output is not bad, but it is difficult to pose a threat to high-level creatures."

Aurora nodded and then asked, "Does the current weaponry think it can fully utilize the advantages of the Titan Machine?"

Upon hearing this, Chu Xiu looked thoughtful and pondered for a while before saying, "Using high mountains as a base allows us to strike the enemy from a superior position, increasing our firing range. In addition, the mountain range itself is a good barrier. Furthermore, as you mentioned, having the mountain absorb the recoil is indeed an advantage over ordinary artillery camps."

"However, I still maintain that this only works against low-level creatures. It is ineffective against enemies of general rank or higher."

"Furthermore, if I may be frank, your current development of the mountain seems to be only superficial. The huge space inside the mountain should be the biggest advantage of building defensive fortifications based on the mountain."

Chu Xiu's words made Aurora show an expression of admiration: "As expected of Mr. Chu, he can see through the essence of the Titan machine so accurately."

"In fact, the Titan machine was not originally planned to look like this. Its current state is merely a last resort."

"Mr. Chu, please come with me."

Aurora led Chu Xiu deeper into the mountain and quickly passed through the ammunition storage room. However, Aurora did not stop but continued to walk deeper into the mountain. There was a secret passage that seemed to have been unused for a long time. The two followed the secret passage and finally arrived at their destination after opening seven blast doors in succession.

Chu Xiu looked surprised. Before him was a huge cylindrical steel tank, with a diameter of over ten meters and a height that was like a stick inserted directly into the mountain. More than thirty meters of it was exposed. It was filled with coolant and had thousands of pipes as thick as an adult's thigh extending from the steel tank into the surrounding mountains.

Chu Xiu extended his divine sense and was surprised to find that these pipes led to hundreds of empty chambers in various corners of the mountain. These chambers either contained circulating coolant or strange large machines.

Inside the steel tank, at its center, is a metal throne with many electrical wires inserted into it.

"This is."

"This is the core weapon conceived when the Titan machine was first built, called [Heavenly Strike Divine Light]."

"When activated, the twelve cannons will unfold from the mountaintop, and the entire mountain will serve as the power supply and cooling system for this weapon. I will personally control these twelve cannons with my will."

Upon hearing this, Chu Xiu couldn't help but carefully examine the enormous object in front of him with his divine sense. After a while, he said, "A laser cannon?" "Yes," Aurora nodded, "Only weapons that can reach the speed of light can effectively fight against those high-level beings."

Chu Xiu nodded in agreement with Aurora's words. The biggest problem with technological weapons is aiming; the more powerful the weapon, the more difficult it is to aim.

At lower levels, there's no need to consider so many things, since no one can escape anyway. But when facing higher-level creatures, you're completely powerless.

Even hypersonic missiles from the previous life needed a complete radar reconnaissance and targeting system to achieve precision guidance, and even then they could only deal with large ships that did not move very fast.

There are only two approaches to dealing with high-level creatures: one is to use nuclear bombs, which reduce aiming errors by infinitely expanding the damage radius; the other is to use laser cannons, which use the high speed of lasers to ensure that the opponent cannot dodge.

Furthermore, the power of lasers should not be underestimated; a 10-kilowatt high-energy laser can cut through a 3mm thick steel plate in six seconds.

However, laser cannons are not so easy to build.

This is a weapon that integrates multiple cutting-edge technologies. First, it must be able to generate sufficiently strong lasers, and second, it must be able to converge these lasers together.

In Chu Xiu's previous life, even the large laser cannons installed on ships had a power of at most 300 kilowatts, which could only be used to destroy some drones and missiles or interfere with the enemy's reconnaissance system, and were also extremely susceptible to weather conditions.

It can be said that it is currently only a research direction and has not yet become a weapon that determines the outcome of the battlefield.

"So, how many kilowatts of output power can your [Heavenly Strike Divine Light] achieve?" Chu Xiu asked.

Aurora coughed lightly, seemingly a little embarrassed: "A single cannon barrel can only achieve a maximum output power of 2000 kilowatts, but it won't last long."

Hearing this, Chu Xiu was speechless. He finally understood why this weapon was abandoned. It was powered and cooled by the entire mountain, but it only achieved the output of 2000 kilowatts for a single cannon barrel, and that was only the instantaneous power. It couldn't last long!

"A 2000-kilowatt laser is probably only enough to burn through a tank in a few seconds."

Even if such power could actually hit a high-level expert, it would probably be insignificant. It would likely require being focused and burned by the twelve cannon barrels for more than ten seconds to cause any damage.

Seeing Chu Xiu's speechless expression, Aurora lowered her head shyly and whispered, "If we activate [Overload], it could go even higher."

The more she spoke, the softer her voice became, until it was almost inaudible.

Chu Xiu smiled and said, "So you want me to help you strengthen this weapon."

“Yes, yes,” Aurora nodded quickly, and as if afraid that Chu Xiu would disagree, she added, “Senior, although this equipment is not very powerful at the moment, its potential is huge. This is the final reward I obtained in the King-level Trial. It is a protective weapon of a technological planet, and its level has even reached [Demigod]! It is a [Mythical] quality [Demigod]!”

"A demigod of mythical quality?" Chu Xiu looked incredulous. The difference was too great. Besides, how could a demigod-level item possibly drop from a King-level trial?

Aurora sighed, "I only received the general outline of the blueprints. There are still fifty-four blueprints left, so I had to research and design the details myself."

"Furthermore, this weapon was originally designed for orbit, but I placed it inside the Titan machine. There were many adjustments needed, and finally..."

"So this is how it ended up, huh?" Chu Xiu said with amusement.

Aurora's cheeks flushed slightly: "But the principle should be correct, it's just that the material strength isn't up to par. Hmm, the standard output power indicated on the blueprints is two billion kilowatts. Although my design is much simplified, it can theoretically reach a power of one million kilowatts."

"Moreover, even ignoring the [Heavenly Strike Divine Light], as long as the cooling system here is strengthened, it can greatly increase my [Overload] time, which can be used as a trump card."

"I understand," Chu Xiu nodded.

If it can reach a power output of one million kilowatts, then it is definitely worth a try.

Upon seeing Chu Xiu agree, Aurora's aquamarine eyes lit up immediately.

Next, the two began to strengthen and upgrade the [Heavenly Strike Divine Light].

Although the equipment was extremely complex, Aurora, as its designer, knew it inside and out, and Chu Xiu's extraordinary divine soul also granted him a computing speed comparable to a computer, so it didn't take long for him to grasp the general principles.

Then Chu Xiu was pleasantly surprised to find that this piece of equipment seemed to have some potential!
Aurora constructed extensive energy facilities and sophisticated cooling circulation systems throughout the mountain, making up for material deficiencies through excellent design and the sheer size of the mountain.

The only thing lacking now is the issue of energy transmission.

The Azure Dragon power that the [Four Symbols Yin Yang Furnace] can bestow includes the attribute of electricity. It is not just about providing additional electric attacks to the vicinity; if used properly, it can also enhance the conductivity of materials.

Strengthening the power supply wires not only greatly increases the current intensity that can be transmitted, but also reduces heat generation, effectively solving both the output and heat dissipation problems.

After a day and a half of enhancement, this piece of equipment finally revealed its true power.

As the refined gasoline burned, a vast amount of electrical energy was continuously transmitted to the [Heavenly Light] through hundreds of large generators and hundreds of thousands of integrated wires. Aurora sat on her throne, with wires connecting to her brain, clearly transmitting all the information about this divine weapon to her mind.

After a while, she opened her eyes in surprise.

"Mr. Chu, how did you manage to do that?!"

"I can feel that the maximum output power of a single gun barrel can now reach 80,000 kilowatts! That's a full forty times!"

The girl's face was filled with surprise and disbelief, and her eyes also showed deep admiration for Chu Xiu.

The weapon she had spent over a decade building was transformed by Chu Xiu in just a day and a half. She would never have believed it if it hadn't happened right in front of her.

In fact, without the abnormal talent of [Perfect Refinement], even with the help of the Eight Desolate Netherfire Array and the Four Symbols Yin-Yang Furnace, Chu Xiu would have needed more than half a year to complete the enhancement.

Chu Xiu was also happy to be able to complete it in just a day and a half.

Each cannon has a power output of 80,000 kilowatts, so the total power output would be 1.2 million kilowatts, which is even higher than the design limit.

Such enormous energy, if all of it were concentrated and hit, would burn through even a king-level creature in a short time.

Even Chu Xiu himself could not withstand it for long using only his physical body.

"As mentioned in the previous explanation, although this trial is only a simulation, it can obtain relics lost in history. If I can obtain this Titan Machine and the Heavenly Strike Divine Light, and bring them back to the Corpse World for the government and Guan Ke to modify, then the defense of civilization will not be a problem."

Chu Xiu thought to himself, his smile growing even wider.

The two exchanged a glance, both filled with confidence for the battle to come.

Next, the two began to meditate to restore their energy and recuperate, preparing to face the final battle in the best possible condition.

Yesterday, the Blood Demon army did not launch a general offensive, but today, the number of envoys from the alien civilization has increased to fifteen, further increasing the probability that the enemy will be unable to resist taking action.

"A Blood Demon [Heroic Spirit] and fifteen powerful Civilization Envoys, many of whom have been enhanced! Under the Blood Demon's command, there are at least dozens, perhaps even hundreds, of King-level subordinates! And the opponent is merely a summoner being constantly worn down. I don't believe you can endure this!"

Chu Xiu could sense that the Blood Demon's attacks were becoming increasingly fierce, aimed at depleting the power of his summoned creatures. This also indicated that the opponent did not intend to survive until the end, but rather planned to launch an attack ahead of schedule.

As Chu Xiu had predicted, just three hours later, a sharp alarm suddenly sounded throughout the entire base city!
Looking down from the mountaintop, Chu Xiu saw hundreds of millions of blood demons scattered throughout the mountains and fields. They stood in the darkness, their scarlet, bloodthirsty pupils fixed on the base city, like countless circles of light covering all the mountains within sight.

Fifteen powerful auras rose from the sky.

The moment of decisive battle has finally arrived.
