After saying what he wanted to say, Director Lin of the Peace Faction turned away, no longer engaging in discussions with Director Gao of the War Faction.

He looked towards the examination hall not far away. In his observation, countless streams of spiritual energy from deep underground were continuously converging towards Ji Yuanxu’s bunker.

With the absolute support of the spiritual ley lines, and the mighty flow of spiritual energy surging forth, the entire formation was operating at its peak.

Under the multiple blessings of the formation’s power, a faint, shimmering glow could be seen emanating from the bunker’s exterior walls, as if a force field enveloped the entire structure.

Not only did it make the entire bunker gleam, but even after the sixth wave of attacks ended, the entire structure remained spotless under the formation’s protection, appearing like the only sacred site in the desolate examination hall.

In contrast, on the other side, because most of the spiritual energy was monopolized by Ji Yuanxu’s bunker, the formation in Zhang Yu’s bunker operated sluggishly, and its reinforcement for the structure was as thin as paper.

Now, after six waves of attacks, although Zhang Yu’s bunker’s main structure was intact, its surface was covered in traces of fire, explosions, and impacts, with the outermost layer of plaster almost completely stripped away.

Compared to Ji Yuanxu’s bunker, its appearance was like the difference between a beggar and a corporate elite.

Anyone witnessing this scene would only conclude that Ji Yuanxu’s bunker was far superior in construction quality to Zhang Yu’s and could withstand future assaults for much longer.

Gongshu Jin sighed internally, “The Finance Department truly deserves its reputation as one of the three ace majors. While Civil Engineering is still focused on how to exert maximum effort, the Finance Department has already completely surpassed us in terms of overall strategy.”

“How can slogging away on a construction site compare to global resource allocation?”

Meanwhile, Ying Xin glanced at Ji Yuanxu’s bunker, then at Zhang Yu’s, thinking to herself, “One looks like a well-funded construction site where overtime is paid, while the other… appears to be a creation where the project is complete but the construction fees are still outstanding.”

She thought, “The outcome is decided.”

Just as similar thoughts arose in everyone’s minds, the seventh wave of attacks arrived.

Blue lightning bolts flickered in the air.

Before the attack even began, the free-floating electrical charges in the air made the hair on the Foundation Establishment Class students stand on end.

Students with strong perception could even feel powerful electromagnetic forces being marshaled above the ceiling, which was over ten meters high.

Gongshu Jin thought, “Is the power of the Yuan Magnetic Passage being deployed? Indeed, each wave of attacks is stronger than the last, with the difference between them growing, allowing for a more precise differentiation of student performance.”

“But this also means the gap between the top students and others will be wider; there won’t be a scenario where someone scores 100 simply because 100 is the maximum.”

“With this wave of lightning techniques, Zhang Yu’s bunker will likely be breached…”

As Gongshu Jin was pondering, bolts of lightning, carrying dazzling electric light like pillars of thunder, struck the two remaining bunkers.

Amidst explosive crackling, the blinding lightning instantly engulfed the entire structure, making it impossible to discern what was happening inside.

As the lightning gradually dissipated, the air filled with the smell of high-temperature scorching. The ground in the center of the examination hall was charred black, and large amounts of sand and soil had melted into a viscous liquid under the intense heat, now gradually cooling to form a glassy substance.

Ji Yuanxu’s bunker still stood amidst the high-temperature fumes, appearing completely unharmed.

To everyone’s surprise, however, Zhang Yu’s bunker, despite its outer walls being covered in charred marks, also remained standing, maintaining its complete main structure.

Even after the eighth wave of attacks, accompanied by intense fiery explosions that then dissipated, a large section of the formation’s glow on Ji Yuanxu’s bunker’s exterior wall was erased.

Furthermore, a massive crack appeared where the formation’s power was weakest, subtly revealing the bunker’s interior.

In contrast, Zhang Yu’s bunker showed no further damage, apart from the increasingly dark scorch marks.

“What?!” Gongshu Jin stared at the scene in shock. “How is this possible?”

The bunker with a perfectly operating formation had a crack blown open.

Yet the bunker with an intermittently functioning formation remained completely undamaged?

Not only Gongshu Jin, but almost all the students present struggled to comprehend how this scene had come about.

Director Lin of the Peace Faction was also slightly startled, but unlike the students who could only guess, his spiritual projection flickered and instantly appeared inside the bunker built by Zhang Yu.

“This is…”

Seeing the reinforced concrete pillars inside the bunker, his eyebrows slightly raised, and a faint conjecture began to form in his mind.

Without further observation, Director Lin waved his hand and summoned the inspection reports for analysis.

Originally, simply by observing the state of both formations, Director Lin had believed Ji Yuanxu had secured victory.

However, the current situation made him realize that things were not so simple.

The next moment, rows of data, photos, video footage, and acceptance evaluations for the bunker appeared before him.

Thirty layers of explosion-proof armor poured…

Isolation layers installed between the foundation and the rock to reduce the transmission of explosion vibrations…

Multi-layered consumption of kinetic energy by sand, gravel, and alloy…

Dense reinforced concrete pillars, multiple parallel load-bearing systems…

And viscous resistance structures at critical nodes, absorbing explosion energy and further mitigating structural damage…

Looking at the detailed records, even Director Lin was slightly taken aback. “So many redundant structures?”

“In just three hours… his construction volume was more than double that of others.”

“Did this young man achieve this purely through civil engineering techniques?”

Just then, Director Gao’s figure appeared beside Director Lin. Looking at the incredibly solid bunker, he smiled faintly. “Director Lin, as you said, which truly impregnable fortress hasn’t been breached from within?”

“The Finance Department might be able to stir up trouble in project matters, but in the examination hall, where there’s only cold rebar and concrete, our Civil Engineering techniques ultimately prevail.”

Director Lin casually dismissed the data displayed before him and sneered, “Director Gao, don’t celebrate too soon.”

“Zhang Yu’s construction efficiency is impressive, but reinforced concrete, no matter how tough, has its limits. It will soon reach its fatigue threshold.”

“However, the blessing of destiny, the prevailing trend, and the convergence of spiritual energy represent the power of heaven and earth, which is boundless.”

His gaze seemed to penetrate numerous obstacles, seeing Ji Yuanxu’s bunker on the other side.

Under the continuous infusion of spiritual ley lines, the previously weakened formation power rapidly recovered to its peak.

“The formation can recover to its peak repeatedly, but can this bunker?”

Director Lin alluded, “With money comes destiny and countless opportunities. Otherwise, no matter how skilled your techniques or how hard your steel, how many defeats can you afford?”

Director Gao looked at him unyieldingly and said calmly, “No one can win forever. I just need to fight until the very end in this battle.”

“Very well, then let’s see who stands last,” Director Lin stared fixedly at him.

At that moment, their wills seemed to cross multiple spiritual realms, clashing and reverberating in the air.

Meanwhile, the ninth wave of attacks descended from the sky.

Bolts of shadowy lightning dispersed, sweeping outwards in all directions with their dark, heavy glow.

Under the impact of the lightning, the formation’s power around Ji Yuanxu’s bunker surged violently. Layers of protection were disintegrated by the shadowy lightning, and signs of collapse began to appear on the outer wall.

As the tenth and strongest wave of attacks arrived, thunder dragons descended from the sky. The resulting explosions, high temperatures, and electromagnetic forces made the nearby students repeatedly recoil.

Ji Yuanxu’s bunker vibrated violently and eventually crumbled under a series of tsunami-like shockwaves.

When the assault finally ceased, only the lowest layer of the original three-story bunker remained.

As for Zhang Yu’s bunker on the other side… apart from a partial collapse of one outer wall, its main structure remained perfectly intact.

Witnessing this, Director Lin’s brows furrowed sharply. “Even with more than double the amount of reinforcement, this shouldn’t be possible. What else did he do?”

With a thought, Zhang Yu’s construction records appeared before him.

Director Gao smiled faintly and instructed Tu Lishan, “Take the students to see it firsthand. Let them learn from it.”

Led by Tu Lishan, Gongshu Jin, Ying Xin, Li Xiao, Yu Xinghan, and others entered the examination hall.

They slowly walked towards the bunker built by Zhang Yu, treading on the still scorching ground.

Upon seeing the extensive redundant structures inside, Gongshu Jin exclaimed in surprise, “He built all of this in just three hours?”

Tu Lishan replied, “That’s what makes Student Zhang Yu so impressive.”

“Bringing you in to see his work today is to show you the true gap between you and him.”

As he spoke, he lightly tapped his finger, and a video appeared before everyone.

For post-examination acceptance, recording, and monitoring, the entire examination process of every student in the hall was filmed and documented.

The video now playing showed Zhang Yu’s construction process.

If the sight of humanoid qi manifestations rushing back and forth, working like an entire construction crew, only slightly surprised the students, then what Tu Lishan said next truly shocked them.

Tu Lishan calmly stated, “Zhang Yu maintained this pace of construction for three full hours.”

Remembering the scenes of Zhang Yu taking medicine repeatedly during construction, Tu Lishan couldn’t help but marvel, “Such drug absorption, bearing capacity, and a robust physique that can be repeatedly pushed… he truly possesses a natural Sacred Civil Engineering Body.”

A thought flashed through his mind, and Tu Lishan continued, “Of course, simply relying on these factors wouldn’t be enough to withstand ten waves of attacks.”

“The key to his success lies in the construction materials.”
