Ten thousand I am across the heavens

The tactics employed by the underground base were unimaginable in conventional warfare, and they made the most of their advantages. The idea of ​​the vacuum tube train was not difficult to come up with, but the problem was that it was difficult to execute.

Even for individual powerhouses in this world, the organization's control and mobilization capabilities at the grassroots level are limited. Mobilizing tens of thousands for a massive project is already quite difficult; deploying millions to execute a major project, ensuring their coordination, and even undertaking life-threatening missions, is beyond the reach of even powerful families with immortals overseeing them.

Such an organizational structure cannot be established through mere force. It requires a large number of proactive individuals who, based on local conditions, adapt to the circumstances, use their ingenuity, and devise solutions to problems. This is done within limited time and resources, and by addressing various unforeseen circumstances encountered during the project.

Just like this track. The vacuum pipe was created at high speed with the help of the immortals, but that doesn't mean that once the underground pipe is created, it can be used. Creating a pipe at high speed is just creating a closed loop without an exit or an entrance. There may also be sealing issues within the pipe. Not all the soil and rocks can be squeezed to the wall to achieve a seal and create a vacuum.

As they were working to break through the tunnel, personnel who had been stationed nearby immediately rushed to the scene. They entered the pipeline with construction equipment and began construction in sections.

The pipes were quickly reinforced with a pre-mixed sealing material. This fiberglass-like material was mixed with a gel-like viscous liquid, sprayed on, and dried rapidly. The layers were stacked together to form a protective layer that combined hardness and toughness, ensuring the pipes were airtight. A metal support was also installed as a second layer of pipe wall.

This layer of protection is in place. When a train turns, if the electromagnetic force is not properly controlled and it is affected by centrifugal force, it may turn towards the pipe wall. These supports can act as a buffer, indirectly bearing the huge centrifugal force of the train.

In addition, construction teams are stationed every few kilometers to build isolation modules. These modules are where trains stop; once the train reaches the target location, it remains within the isolation module, which is then disconnected from the other modules. This ensures that the entire tunnel maintains a near-vacuum environment. Air is then reintroduced into the isolation modules, propelling the train to the surface, where the attack can then commence.

In this way, it is possible to quickly enter and exit the vacuum tube without worrying that the vacuum tube must be evacuated again every time you come out.

These complex steps require the coordinated efforts of numerous professionals, engineers, and workers. Without this, simply digging an underground tunnel, even with some sophisticated techniques to create a vacuum, would take a very long time. Creating such a unique battlefield environment by individual effort would likely take several months or even longer; by then, it would be too late.

As for the underground base, they not only had time to create a circular ring, but also a series of smaller rings within a larger one, like an underground overpass. Not only did the outermost ring have exits, but smaller rings closer to the eldest son also had exits, allowing for accelerated transfers to locations closer to or further from Zhang Zi, providing more options.

A large number of engineers and workers are stationed throughout the loop tunnel. They are responsible for inspecting and controlling manually operated facilities such as isolating sections, calculating train speeds and arrival times at stations, and closing the airlocks of isolating sections and raising the trains as quickly as possible. Even if a train is damaged, they are responsible for replacing parts and repairing it immediately.

Qin Baisheng watched helplessly as all this unfolded before his eyes, only able to sigh in despair. This tactic held a significant advantage even in battles between immortals. It was incredibly difficult for a latecomer to disrupt it. The underground vacuum pipes were constructed in sections, like ship hulls. Destroying one section maintained the vacuum in the others. Trying to enter the pipes and move quickly in the same way, thus wiping out the difference in mobility, was impossible. The side controlling the vacuum pipes could directly inject air into them. Even if they couldn't inject air initially, closing the isolation gates later would allow the pursuers to accelerate, or even force them to crash into the isolation gates at high speed.

At speeds of tens of kilometers per second or even faster, the damage to a robust metal isolation chamber would be unimaginable. Even an immortal wouldn't want to bear such a heavy impact. With such a formidable design, even if an immortal were to attempt to break through, the difficulty would be immense. Furthermore, with the coordinated efforts of numerous engineers, the rate of destruction wouldn't even outpace the rate of construction.

The eldest son is now trapped in a network of underground tunnels. Large loops within smaller loops, surrounded by densely packed isolation chambers that allow trains to rise to the surface, while legion members will travel at high speed on these trains, launching attacks on the eldest son from various directions.

The diameter of the giant circle is almost comparable to that of a planet. Even with the incredible speed of immortals, circling its edge without the aid of underground vacuum tunnels would take about a day. Without considering deceleration, circling it could be completed in as little as seventeen minutes. If acceleration followed by deceleration is taken, exiting from roughly the same position, the entire process would take about 35 minutes. This immense advantage in mobility is only just beginning to emerge. If the infrastructure-building capabilities of this "infrastructure maniac" are further developed and this technology is spread throughout the Northern Plains, regardless of whether they are ultimately destroyed, their legacy will be inherited by countless generations, potentially even altering the entire world's war landscape.

Given the organizational capabilities of these ruthless individuals, it's entirely possible for them to spread something of this caliber throughout the world. He vaguely knew that the Shanhe Republic had even stronger infrastructure capabilities, having already undergone over a decade of development. It was hard to imagine what they had transformed the Southern Frontier into; their manpower, resources, and the number of high-level experts far surpassed those of the underground base by tens of thousands of times. The thought of facing the Shanhe Republic's home-field advantage in such a place gave Qin Baisheng a headache.

His true identity is one of the incarnations of the Ghostly Demon Lord. Therefore, he knows a great many secrets, including the existence of the Destiny Gu and the mission of the Heavenly Court.

Logically, history should proceed along a predetermined trajectory. Even if someone could travel back in time and alter the flow of time, the ultimate trend wouldn't change significantly. It's like a river flowing for thousands of years; although it may be gradually modified occasionally, its general direction remains constant. However, the emergence of the Republic is like forcefully twisting the river of time in a completely different direction, onto a new course. No one knows where it will flow in the future.

Now it seems the impact of fate being forcibly reversed by external forces may be even more profound. He vaguely knew the direction of fate, so the existence of the underground base seemed somewhat incongruous in comparison. Especially since their approach to difficulties was very similar to that of the Mountain and River Republic. Those who hadn't worked closely with them wouldn't notice this. But he had already vaguely noticed it.

Several times he considered secretly breaking the previous alliance, even though a contract had been made between the two sides. Violation would come at a considerable cost, but given his resources and capabilities, he could afford to bear it. If he were willing to launch a sneak attack, destroying these four top-tier legions was entirely within his power.

After a brief hesitation, he gave up. He was not burdened with the mission of the Heavenly Court, and he was completely different from the Heavenly Court. The Ghostly Demon Lord had been playing a grand game all along. Every Venerable would eventually reach the end of their lifespan. Even the original Primordial Immortal Venerable only lived for a little over 2 years, because the Longevity Gu produced by heaven and earth was either used up as soon as it was produced, or its production was too low to sustain its continued existence. Thus, it could no longer prolong its life.

Only by transcending the realm of a Venerable can one achieve true immortality and reach a higher realm. No Venerable has yet accomplished this, and each Venerable is playing a grand game, attempting to break through and achieve true immortality.

What the Ghostly Demon Lord needs to do is secretly collect 10 types of ultimate physiques, also known as the Ten Absolute Physiques, and gather 10 immortals with these special physiques. Using their bodies and countless precious materials, he will refine a Gu worm that nearly surpasses the Nine-Turn Immortal Gu, the Supreme Immortal Embryo Gu. Then, he will use this Gu worm to complete his rebirth. At that time, he will possess the most perfect body in the world, and with this body, he can once again become a Venerable, perhaps even breaking the threshold of immortality and reaching a realm beyond the Venerable.

However, all these actions defied the will of Heaven, and the Heavenly Court and Heaven's Will would secretly thwart them. Therefore, when making his plans, the Ghostly Demon Lord knew that his scheme could not succeed step by step. Fang Yuan, this extraterrestrial demon, was precisely the person he and many other hidden powerful beings had chosen.

It wasn't that he possessed any special talent. While his identity as an extraterrestrial demon was indeed special, this world was never short of transmigrators. Countless transmigrators had existed over the past 300 million years. But only Fang Yuan had the temperament to become a powerful being. Before his first incarnation as an immortal, he received almost no external help, relying solely on luck and his own hard work to reach a level close to immortality. Historically, only a handful of extraterrestrial demons had achieved this. And to completely destroy the Destiny Gu, even a Venerable couldn't do it; it required the soul of an extraterrestrial demon to cooperate, along with a body that also didn't belong to this world—a Supreme Immortal Embryo—to have any chance of doing so.

Therefore, the Ghost Demon Lord's plan was to turn the tables on Fang Yuan, causing his plan to be reborn to fail, so that Fang Yuan would use the body he had prepared to destroy the Destiny Gu, and then he would find a way to take back his own body.

However, utilizing someone who transcends fate also comes with corresponding risks. Fang Yuan's actions are unpredictable, and if the Ghostly Demon Lord is not careful, he might end up with nothing.

Qin Baisheng, as one of the clones, was initially sealed of his memories and remained in the Northern Plains as an important hidden pawn. However, due to the unexpected rise of the Shanhe Republic, the Southern Frontier, originally the location for the ritual of refining Gu, lost control. They had to temporarily relocate, and Qin Baisheng was used to restore his original memories.

He now knows the whole story. And from his original perspective, compared to executing the original, extremely risky plan, there's now another path to take. That is to allow the Mountain and River Republic and forces like them to develop. They are like a flood, destined to eventually breach the dam of the Heavenly Court. And these numerous beings who defy fate will also inflict immense damage on the Destiny Gu. Their very existence constantly challenges destiny; if they grow stronger, there's a possibility that the Destiny Gu might gradually deteriorate or even die without needing to attack the Heavenly Court.

This made the Ghostly Demon Lord's clones want to abandon their original plans and wait. A conflict between the Heavenly Court and the Mountain and River Republic was inevitable, and regardless of who won, the other side would pay a heavy price. Mount Tai and the Republic were currently at their zenith, but their accumulation of power was ultimately too short-lived. On the surface, the Heavenly Court did not appear as powerful as the Mountain and River Republic, which had expanded its strength in such a short time. However, the foundation accumulated over 300 million years was not to be underestimated. If a conflict truly broke out, the current Mountain and River Republic would suffer heavy losses and might even be destroyed by some supreme power.

If that's the case, why not wait until both sides are exhausted and fate is powerless to interfere before refining the Supreme Immortal Embryo Gu for the user's own use?
Now, as long as we cooperate with these mortals and complete some insignificant tasks, we can obtain the precious Longevity Gu, and judging from their expressions, they seem to be offering even more, creating opportunities for future cooperation. Therefore, there's really no need to consider eliminating them now.
