Not enough Japanese devils to kill? 1.4 billion people volunteer for the Battle of Shanghai.

"Sixth crossing of the Shanghai-Nanjing battlefield countdown... 2 hours 11 minutes"

"Squad Leader Bian." A smartly dressed female soldier approached Bian Yun and whispered, "I am an angel."

"Hello," Bian Yun greeted.

The angel held a hemostatic agent in her hand. She looked at Bian Yun with a calm expression: "Captain Bian, I have only one request—once we get there, the wounded must be brought here as quickly as possible. For some injuries, a ten-minute delay can mean the difference between life and death."

Bian Yun nodded solemnly: "I promise."

Iron Anvil had somehow appeared beside Bian Yun, holding a piece of armor that had just been removed.

"Squad leader, look at this. The frontal armor plate has an effective penetration resistance of 800 mm at its thickest point. In 1937... even if the Japanese brought all their artillery together to bombard it, they still couldn't penetrate it."

"What are these used for?" Bian Yun asked. "Are you suggesting people carry armor plates while charging into battle?"

"Of course not." Iron Anvil laughed. "These armor plates will be transported to the Luodian front to reinforce key firing points. Imagine using 2025 armor plates to build a machine gun bunker in 1937—the Japanese grenade launchers and infantry guns wouldn't even leave a mark on it."

"But we have the Kirin tank, capable of indiscriminate bombardment and sending the Japanese devils to their deaths. As for those lightly armored Japanese tanks..."

He made an explosion gesture: "It's made of paper."

Bian Yun imagined that scene and smiled.

Meanwhile, in the center of the underground base, the engineers had already begun their work.

"Separate the fire control system!" the engineering team leader shouted, "Watch out for the optical lenses! You can't find replacements for them in 1937!"

Next to it, the dismantling of the main gun of the Qilin tank was even more spectacular.

The 125mm smoothbore gun has a barrel that is 6.8 meters long and weighs 1.8 tons.

When the robotic arm lifted the cannon barrel, the soldiers around held their breath.

This steel behemoth, capable of penetrating the armor of any main battle tank by 2025, is about to be brought to the bloody battlefield of 88 years ago.

"Barrel sections!" the engineer shouted. "Remember the connection markings! We need to be able to assemble them quickly once we get there!"

The most ingenious part is the disassembly of the active defense system.

The "Kirin" active defense system consists of four parts: millimeter-wave radar, high-speed computer, interceptor missile launcher, and fragmentation interceptor missile.

This system can destroy a tank 0.3 seconds before an incoming shell hits it, making it a "golden shield" for tanks in 2025.

While the dismantling work was underway, the thirty elite marines, divided into fifteen groups of two, were conducting final regrouping and tactical simulations.

There were a total of thirty-two people crossing the Songhu River this time.

Bian Yun, as the team leader, and Angel, as the medical officer, are not in the combat sequence.

Bian Yun, accompanied by the angel, entered the preparation area for the elite soldiers.

The first group immediately caught his attention—a lean, leopard-like man was explaining something to a young man wearing glasses.

The two formed a stark contrast: one exuded a wild, powerful energy, while the other possessed a scholarly calmness.

"I'm Cheetah, the wingman knows me. This is my partner, the hub." Cheetah introduced himself: "He's the 'brain' of the Eastern Theater Command's tactical command center."

He patted the hub on the shoulder.

"When we arrived at Luodian, I was in charge of killing, and he was in charge of figuring out how to kill more efficiently."

The second group consisted of two burly men, both over 1.8 meters tall, with bulging muscles on their arms. They were inspecting a 125mm gun barrel that had just been removed.

"Anvil and the breacher." Anvil wiped the machine oil off his face.

"We both came from armored corps backgrounds and know how to use artillery. When we got there, our group was responsible for teaching the other guys how to use this thing."

The third group consisted of a man and a woman, who were organizing a large number of miniature drones.

"The Queen Bee and the Red-crowned Crane." The Queen Bee—the drone PhD from the National University of Defense Technology—looked up to greet us. "I brought two hundred 'Hummingbird' reconnaissance drones and fifty 'Peregrine Falcon' attack drones. Sister Red-crowned Crane is in charge of ground reconnaissance and close-combat protection."

The red-crowned crane inspected the submachine gun in its hand without looking up: "The urban warfare environment in Luodian is complex, and drones have blind spots. I'll fill them in."

The fourth group surprised Bian Yun – it consisted of two female soldiers.

"The embroiderer and Fu Hao." The embroiderer is assembling something that looks like a mecha.

After assembling it, the embroiderer pointed to the female soldier next to her who was already wearing the exoskeleton system, "Don't underestimate Fu Hao. She holds the record for the most exoskeleton operations in the entire army. She can carry 100 kilograms and run 5 kilometers across the road."

Fu Hao raised her head; her face was delicate and pretty, but her eyes were resolute.

"By 1937, a lot of heavy equipment had to be transported using exoskeletons. I promise that no cannon will be left idle because it can't be moved."

Group 5, Group 6, Group 7...

Bian Yun looked at each group one by one.

There is a combination of "Dynamite" who is good at demolitions and "Hunter" who is proficient in traps.

—They said they would set up "death corridors" along the Japanese army's attack route.

It features a combination of electronic warfare expert "Ghost" and communications mastermind "Messenger"—

They wanted to paralyze the Japanese army's command and communications while simultaneously establishing our own anti-jamming communication network.

There was a sniper instructor named "Eagle Eye" and an observer named "Binoculars"—their target was all Japanese officers within a five-kilometer radius.

It features the engineering master "Cornerstone" and the field cook "Kitchen God" duo—

One was in charge of repairing the fortifications, and the other was in charge of ensuring everyone had a hot meal.

Eating is very important, even Bian Yun has to admit that.

Each pair of them has a clear division of labor, complementary skills, and a complete set of combat plans.

They prepared quietly, checking equipment, adjusting devices, and studying maps.

But Bian Yun could see the same thing in their eyes—

A ball of fire.

A fire of revenge, suppressed for too long, finally found an outlet.

At 2 a.m., the dismantling work entered the precision cutting stage.

The 32-cubic-meter space was planned by engineers with the precision of the interior of a Swiss watch.

"This is the most extravagant 32 cubic meters in human history."

The chief engineer wiped his brow, his tone filled with pride.

"This contains the core combat capability of fifteen main battle tanks for the Chinese Army by 2025. If you put it in 1937..."

He didn't finish speaking, but everyone understood.

These 32 cubic meters were enough to change the course of the Battle of Luodian.

Bian Yun stood beside the 32 cubic meters, looking at the countdown in his mind:

"Sixth crossing of the Songhu battlefield countdown - 20 minutes."
