After exchanging pleasantries with the soldiers, Su Jie pointed to the huge underground base and asked Liu Yingying for her thoughts.
"Having inspected our Earth Dome System along the way, what do you think?"
"An inconceivable human miracle."
Liu Yingying's eyes widened, not hiding her astonishment.
Construction underground is extremely difficult, let alone such a massive and complex engineering project.
Su Jie chuckled and said, "The Eight Nation Group thinks they can destroy our military power with air strikes, but what they can think of, we naturally consider how to deal with."
The underground base in front of them was naturally Su Jie's masterpiece, to be precise, the fruit of Xiao Qian's arduous labor.
The so-called Earth Dome System was to create a network of transportation and military routes spread across the underground.
The thousand-hand centipede was employed for subterranean excavation, with other engineering soldiers fixing and patching up things.
Initially, this project was somewhat difficult to complete on time, but then Su Jie enhanced the mandibles of the thousand-hand centipede, which were capable of snapping top grade magical artifacts. Rather than using them for combat, they were first put to work in digging, significantly increasing the efficiency of the centipede's excavation.
The entire Earth Dome System was structured around twelve large underground bases as the backbone, interconnected through underground tunnels, and using an underground railway and road network for the transportation of materials and troops.
These underground bases included ones located in the rear, specifically for manufacturing military supplies, ones for ammunition storage, as well as specialized soldier training bases.
Besides these large underground bases, there were also medium-sized and small-sized bases scattered throughout Ji State and East Qin State, stretching all the way to the edge of the Ruo Kai Mountains.
The Jieke Group's army had already entered underground from the surface when the war broke out, fragmenting their formation.
Together with various strategic material storages, most built above ground were merely for show, meant for the Eight Nation Group to bomb.
The truly important material storages had long been transferred underground.
With this Earth Dome System in place, Jieke Group suffered minimal losses in troops and supplies during the massive bombardment by Japan, nowhere near the countless casualties they claimed.
With the existence of the Earth Dome System, Jieke Group could also completely conceal and protect itself.
Otherwise, marching on the surface and transporting supplies, under Japan's control of air superiority and satellite reconnaissance, Jieke Group's soldiers would have no idea how many bombs they would suffer from or how much material they would lose.
If even half of the troops reached the front line, it would be considered good.
"The Japanese Commander even declared that we should surrender within three days."
Liu Yingying pursed her lips, looking at the endless flow of cars, trains, and soldiers in the underground base, wondering what someone like Yoshimura Yuichi, the commander, would think if he saw this scene.
"Without giving them a chance to see the opportunity, how would they dare to enter the Ruo Kai Mountains so easily? And if they don't enter there, how can we bleed them?"
Su Jie's eyes were sharp as he watched the columns of vehicles loaded with soldiers and supplies, mockingly saying, "They call this Operation Typhoon, but a typhoon cannot destroy the Ruo Kai Mountains. Soon Jieke Group will make all Japanese Soldiers who intrude into the Ruo Kai Mountains understand who truly rules this land."
Japan did not go back on its word, and when the air assault achieved splendid progress, it sent a large number of ground troops in conjunction with the Chan Country Government Army.
And in the Ruo Kai Mountains, where artillery positions had been brought in, countless heavy artillery began to roar like the gods, coordinating with the air strikes. Projectiles fell like raindrops, indiscriminately bombing the places where Jieke Group might have outposts, barracks, and fortresses.
With support from the Beautiful Country in terms of materials, Japan and the Chan Country Government were utterly indifferent to this expenditure of ammunition.
In the Ruo Kai Mountains, there is a road to Ji State territory called Sin Fan Avenue, which is also the real strategic chokepoint.
If they want to move the army into Ji State, this is the fastest route, despite the road being rough and broken, but it's still a road; otherwise, they would have to go through the primitive forests across the mountains, which is not the Eight Nation Group's first choice.
This Sin Fan Avenue, at the forefront of the Ruo Kai Mountains, is guarded by a peak known as Twin Peaks. Sin Fan Avenue passes right between the two mountains.
These Twin Peaks stand like towering guardians, guarding the passage on Sin Fan Avenue.
This place was also occupied by Jieke Group during the last invasion of Ji State.
The best way to enter Ji State is through Sin Fan Avenue, and to take Sin Fan Avenue, the Twin Peaks must be taken down.
To capture Twin Peaks, the Eight Nation Group carried out the most ferocious and random bombardment here.
Within just a week, they bombarded the Twin Peaks with over fifty thousand tons of ammunition.
The tens of thousands of Jieke Group soldiers stationed there endured an average of five tons of explosives each. The mountains were sheared down by tens of meters, and not a single blade of grass could survive.
After a week of bombing, accompanied by ground tremors, a large number of armored personnel carriers and tanks arrived at the foot of Twin Peaks.
These vehicles couldn't go up the mountain and could only send infantry to advance and take over.
"Those Jieke Group bastards must be dead by now."
Matsumoto Xiao Yilang sat on top of a tank, swaying with the motion of the vehicle, excitedly gazing at the Twin Peaks in the distance, now blasted into a scorched wasteland.
"With such fierce firepower coverage, even an iron man would have been shattered. I guess our job going up there is probably to collect the corpses of those Jieke Group soldiers, if they have any intact bodies left, hahaha."
"Even better, they only deserve such treatment. Being obliterated is lucky for them; at least they die swiftly. Otherwise, if I catch them, I will make sure they understand my methods."
