Ten thousand I am across the heavens

Although the population of the underground base has not yet surpassed the total population of the Earth in the 21st century, it has already shown some of the prowess of an infrastructure powerhouse.

More than 3000 construction teams worked day and night at different locations, occupying almost every possible construction site on the grassland.

They began driving stake after stake deep into the ground. These were used to disrupt the wind and snow across the entire grassland.

Calculations were performed based on data transmitted from the surveying department. Research institutions discovered that the annual blizzard resembled a legendary natural disaster, although its manifestation differed and its scale was far greater than typical natural disasters. However, the numerous similarities allowed them to utilize these characteristics to reduce the blizzard, which would otherwise spread across the entire grassland, to its original state. These key points were selected after precise calculations.

Although they didn't have much knowledge about array formations, it was undeniably useful. After precise calculations, they drove each stake into the key nodes of the super array set up by the Great Sun Immortal Venerable.

The once-in-a-decade super blizzard was created by the Giant Sun Immortal Venerable back then. One reason was to create an opportunity for a royal court conflict; without the blizzard, there would be no need for everyone to fight to the death.

On the other hand, it can also be used to guide natural disasters and calamities from the Royal Court Blessed Land outwards. Furthermore, natural disasters from other blessed lands and grotto-heavens can also be guided out in this way.

In this way, the royal blessed land is no longer affected by natural disasters and calamities, and there is no need to worry that it will be destroyed and rendered unusable over time. However, this also means that the inhabitants of the grasslands have to endure the baptism of natural disasters and calamities every year. Although the effects have been diluted to some extent, they have still caused countless casualties over tens of thousands of years.

Finally, this special formation also serves another purpose: collecting treasures from the grasslands. Any treasure of sufficient value will be collected by the formation amidst the blizzard and gathered into the Eighty-Eight Corners True Yang Tower. This means that any naturally occurring immortal insects on the grasslands will be automatically collected immediately and become collectibles within the Eighty-Eight Corners True Yang Tower.

At this moment, the formation was being used in reverse; after key nodes were driven into place with stakes, the flow of the formation changed. The underground base initially believed they were leveraging favorable timing and location, using the unique environment created by nature to guide the formation's operation and unleash its terrifying power. In reality, they were directly borrowing the arrangement made by the Giant Sun Immortal Venerable, simply going with the flow. Only a contingency plan left by a powerhouse of this caliber could pose a fatal threat to a super-creature like the Eldest Son.

After all, in this extraordinary world, countless races waged various struggles before their extinction. Even interstellar races capable of interstellar travel ultimately had no choice but to flee when faced with the Firstborn. Without the protection of ancient races, these powerful interstellar races couldn't even escape. While the underground base possessed some supernatural power, which of those interstellar races lacked magical or other supernatural abilities? To fight the Firstborn, or even eliminate him, on their own was virtually impossible.

"I think everyone understands that we can't possibly defeat the eldest son alone, no matter what. Even if we're determined to uphold this world, we still need to consider methods and strategies. Therefore, I've decided to use the Longevity Gu that the organization assigned to me as a bargaining chip for our next strategic move," He Cheng stated at the meeting. This statement left the others thoughtful.

Longevity Gu is a rather special type of Gu worm, falling somewhere between Heavenly Dao Gu worms and Human Dao Gu worms. The will of Heaven can influence the production of Longevity Gu, while the degree of population concentration determines whether Longevity Gu can be produced.

Because no one can predict where this type of Gu worm will be born, the Longevity Gu has become a Gu worm that is difficult for immortals to obtain, but quite likely to be acquired by mortals. After all, if a Gu worm is born in the vast sea of ​​humanity, even an immortal with immense abilities cannot discover it immediately. And if mortals obtain this Gu worm, they mostly use it directly for themselves, instantly adding several or even decades to their lifespan. Therefore, even immortals who want to obtain this Gu worm need to pay a high price and rely heavily on luck.

The underground base has a large population and a certain degree of control over the entire grassland. Therefore, it actually has a certain reserve of Longevity Gu. Relying on the strong organizational power and cohesion brought by the organizational framework, most of the naturally born Longevity Gu have been collected by the authorities. They are then distributed to people with special talents or superior intelligence, so that these people can live as long as possible and make greater contributions to the people.

"Longevity Gu is one of the few types of Gu worms that even immortals crave, sometimes even more precious than Immortal Gu. Using it on me would be a waste. After all, none of the highest commanders in our underground base have ever died of old age. Now that it's my turn, we don't even know if I'll live past the end of the year. Using it on me would be a complete waste."

My idea is to use the Longevity Gu as leverage to demand the cooperation of the immortals. They would provide us with ample immortal energy to unleash our ultimate immortal techniques. While the Star-Trapping Gu might attract extraterrestrial visitors, if we develop other uses for it, employing conventional immortal techniques, we can still execute them and unleash their full power.

With the cooperation of the immortals and our legion, we can unleash a deadly war move using the power of the immortal Gu. Its power could potentially be a thousand times greater, further increasing the probability of killing the eldest son.

According to reports from frontline observers, the two immortals who are currently trying to stop the eldest son are showing signs of backing down. Unless there are sufficient benefits to be gained, they probably won't continue to expend their precious resources to suppress the eldest son.

Indeed, both immortals had their own selfish motives. While the Five Elements Mage was willing to fight the natural disaster out of a sense of righteousness, he was also aware of his own limitations and wouldn't directly use his own resources. He would only use the White Lychee Immortal Essence he recovered monthly, instead of consuming the Immortal Essence Stones he had accumulated. As for the unfortunate Old Ancestor Xuehu, whose spawn point was blocked, he certainly wouldn't go all out; so far, we haven't seen them truly unleash their full power.

Seeing that the eldest son was beyond their ability to eliminate in a short time, the two experts were already considering retreating. There were so many experts on the grasslands, even many eighth-level powerhouses; why should they be the ones to bear the brunt?

While the eldest son's development was slowed down due to their suppression, it continued to frantically devour the world's matter and the creatures of the grasslands. Its size had already expanded to more than ten times its initial size upon landing, and the rate of expansion was exponential. The larger its size, the faster it could collect and transform surrounding matter. In another half month, its size would likely expand to a hundred times its initial size upon landing, at which point it would truly approach the size of a planet.

"The leader is right. Take the longevity worm that the organization assigned to me. Although I am now the leader of the research department, it doesn't mean I am a true genius. A large number of children have not yet received a complete compulsory education. My talent among them may only be considered above average. After they grow up, I will be just an average person. There is no need to waste such a precious worm on me."

Xiao Lu also stepped forward to express the same viewpoint. Immediately, one after another, key figures from the underground bases stepped forward, contributing the life-extinction Gu allocated to them by the organization, intending to use them as funds for the upcoming operation.

With the addition of the stored Longevity Gu and the various underground bases, a total of 500-year-old Longevity Gu had been accumulated. This wealth would make even an eighth-level immortal envious, but now it had to be spent without hesitation. Even with a large population and the ability to steadily produce Longevity Gu, it was still heartbreaking. But this was the price to pay for fighting against an apocalyptic catastrophe.

News of this soon spread like wildfire throughout Baohuang Tianzhong. A 30-year-old longevity Gu had been born atop the Northern Garden, and it was now in the hands of the underground base that had caused quite a stir in the mortal realm. They claimed they would use this longevity Gu as a price to ask the immortals to intervene and help them suppress the eldest son.

Baohuangtian is indeed a trustworthy trading institution. After hanging the Gu worms on it, there's not much to worry about them being stolen. As long as both parties fulfill their promises, the Gu worms will naturally be delivered as agreed.

A thirty-year-old Longevity Gu is an extremely rare and highly sought-after commodity, worth around a thousand Immortal Essence Stones on the market. Even then, it's a type that money can't buy. An ordinary sixth-rank Gu Master might only accumulate a few hundred Immortal Essence Stones over many years, which translates to a yearly income of perhaps only two or three hundred Immortal Essence Stones.

However, considering that the Longevity Gu can directly extend lifespan, and is almost the only way to preserve strength and prolong life, a thirty-year Longevity Gu costs around a thousand Immortal Essence Stones on the market. It's really not considered very expensive.

The underground base offered 500 Immortal Essence Stones, plus a seventh-rank or higher powerhouse to join their legion in battle and suppress the eldest son's growth.

Longevity Gu for sale is not a common sight in Baohuang Heaven, and now a mortal is actually selling it at a discount. A large crowd quickly gathered, eager to ask an immortal for help. Many could only shake their heads and sigh at the sight of the Gu, for crossing the Five Domains barrier was far too difficult for them, as they were not in the Northern Plains. Even immortals struggled to protect themselves when crossing such barriers, and their strength would be suppressed upon reaching other domains, making them unsuitable for this task. Meanwhile, the immortals of this garden were going crazy for it; they only needed to make one move to get a Longevity Gu at half price. They had never heard of Longevity Gu being discounted before. Previously, without a single immortal Gu, acquiring a Longevity Gu was practically a dream come true; even in Baohuang Heaven, it was rare to find Longevity Gu available for the price of common items like immortal essence stones.

The professionals dispatched from the underground base conducted a rigorous screening of the buyers. Among the many immortals who wanted to purchase, they selected the one with the most suitable abilities and the required level of strength before preparing for the first collaboration.

They can take half of the five hundred immortal stones, and the other half, along with the longevity gu they provided, will be pledged at Baohuangtian and paid out together after the transaction is completed.

The first person chosen by the underground base to cooperate was named Qin Baisheng, who was said to be one of the most powerful seventh-rank Gu Immortals in the Northern Plains. It was precisely because of his formidable strength that they were willing to cooperate with such a master to further suppress the eldest son.

Before carrying out the plan to exterminate the eldest son, they had to suppress his growth to ensure that the behemoth would not grow to an excessively large extent when the extermination plan began.

Qin Baisheng had an overwhelming advantage in strength and easily defeated all his competitors. The two sides agreed to meet at a tribal ruin in the south of where the eldest son was rampaging.

Qin Baisheng actually felt that it was pointless for these mortals to join the battle. In a battle of this level, mortals were completely useless, and would even be a burden if they were to be protected. But since it was his employer's request, he had no choice. As long as he completed this hired operation according to the agreement, he would definitely obtain the Longevity Gu.

Speed ​​is of the essence in war, and both sides arrived at the agreed location on the same day. The Eleventh Legion, the Thirteenth Legion, the Snowman Legion, and the Eighth Legion all participated in this operation.

Relatively speaking, the Eighth Burning Legion is the weakest of the four legions. It was sent here because when Blue Fox commanded the Eighth Legion, he deeply developed the ability of attribute conversion and created the Blessing of Eternal Radiance. This ability can forcibly freeze the legion at its most brilliant moment for a certain period of time, maintaining terrifying combat power until all its power is exhausted.

This means that with the assistance of immortals, the Eighth Legion's most brilliant combat power would be extremely terrifying. Even without the immortals' assistance, using the Blessing of Eternal Radiance again, though the cost would be enormous, would still yield a terrifying combat power that remains strategically significant.

Seeing the disciplined and well-equipped army, arrayed in perfect formation, awaiting his arrival, Qin Baisheng couldn't help but recall his pre-immortal days. Back then, upon seeing such an army, he probably would have turned tail and fled. But now, to him, these soldiers on the ground were nothing more than ants.

It's normal to have this kind of idea, after all, Cedarnut wouldn't go around the grasslands advertising that it was beaten up by a bunch of mortals.
