He's alone, but he's a tomb raider!

This place was not safe to stay any longer, and he dared not fight Qin Yun to the death again.

After activating the mechanism on the coffin, the protective array in the tomb was removed.

Ao Bai suddenly changed direction, his burly body slamming into a side chamber where weapons were stored, attempting to break through by force.

Having lived here for hundreds of years, Ao Bai was quite familiar with the surrounding area.

Several decades ago, a group of short men wearing yellowish-brown military uniforms and carrying Japanese flags built an underground base next to the tomb.

Just now, Ao Bai vaguely sensed that a peerless and deadly weapon had appeared in that base.

Its aura was chilling and domineering, almost as powerful as his own Hundred Battles Blood Fiend Blade.

If we could seize it, we might be able to subdue this opponent who wields golden light and thunder magic.

"Hold on! If we can escape to the base and find the killer knife, we can turn the tide of the battle!"

……

Boom—!

Rock fragments flew everywhere, and dust filled the sky.

Wearing the tattered Xuanzhu Locking Spirit Armor, Ao Bai, relying on the supreme strength of his innate Golden Body, did not bother to detour through the passage. His entire gilded body charged forward recklessly, smashing through the Qing Dynasty tomb stone wall, which was several feet thick.

After the wall collapsed, what was inside was not a tomb chamber, but a completely black, cold, hard, yet extremely well-organized artificial passageway.

Upon closer inspection, what else could it be but reinforced concrete!

The old-fashioned high-grade cement from a century ago, after decades of dampness and corrosion underground, remains as hard as iron, with regular edges and corners.

This is a unique architectural style of modern military fortifications.

Without time to think too much, Ao Bai slammed his shoulder into the concrete barrier, which was nearly a meter thick, and knocked it down again.

With a flash, he vanished completely into the dark and deep underground base.

Qin Yun stood amidst the rubble without the slightest hesitation.

If you try to kill a snake but fail, you'll get bitten instead!

Since we've already torn off all pretenses, we must nip it in the bud!

This trip to the Ao Bai tomb in Northeast China seems to be about tomb raiding and treasure hunting, but also about developing a system along the way.

But besides that, there is another crucial objective.

To find a suitable corpse for Liu Yanyan, who comes from the Liu family in western Hunan.

If Ao Bai were to stay, it would naturally be a win-win situation for everyone.

Liu Yanyan benefited from the deal, and now she had an excuse to pocket all the treasures in the entire tomb.

Moreover, since she had accepted his gifts, Liu Yanyan would likely not speak carelessly about the methods he had displayed.

But what if Ao Bai gets away...

Just in case, Qin Yun had no choice but to kill Liu Yanyan to silence her.

However, this would inevitably offend the Liu family to the death, which would seem like a loss rather than a gain.

Furthermore, the Mysterious Pearl Locking Armor is still on Ao Bai's body.

Those are my things, how can I let him take them away!

Without coveting the burial treasures scattered on the ground, and without having time to examine them closely, Qin Yun strode onto the nine-tiered platform and waved his hand.

The entire thousand-pound golden nanmu coffin, along with all the remaining burial treasures and hidden artifacts in the bottom compartment, was stored intact in his imaginary space.

Having done all this, Qin Yun unleashed the Ascension Step, his figure flashing and disappearing in an instant, following the huge hole created by Ao Bai, and went straight into the cold, dark underground base of the Kwantung Army.

Meanwhile, Liu Yanyan, who had been hiding in the corner of the side room, watched the entire match with her breath held.

Seeing Qin Yun set off, she dared not stay alone in the tomb and hurriedly ran after him.

……

As you pass through the broken tomb walls and step into the base, a bone-chilling cold mixed with the combined smells of rust, gunpowder, mold, and engine oil hits you.

The scene before them far exceeded Qin Yun and his companion's expectations.

This is not a simple underground base or temporary warehouse at all.

Judging from its scale, the underground base in front of us is several times larger than Ao Bai's tomb, and almost the entire mountain has been completely hollowed out!

The reinforced concrete structures are layered and interwoven, with seven layers in total, and stretching for nearly a kilometer horizontally.

The dome is constructed with giant load-bearing steel beams, and the walls, columns, and blast doors are all made of thickened military-grade concrete.

It is blast-resistant, collapse-resistant, and earthquake-resistant, making it a standard permanent super-large military fortress.

The passageway is wide and straight, allowing passage for military trucks and tracked armored vehicles.

Neatly arranged on both sides are rows of barracks, armories, ammunition depots, medical rooms, interrogation rooms, communications rooms, secret cells, and secret laboratories.

In addition, well-preserved Japanese military equipment and supplies can be seen everywhere.

Rows of neatly stacked hand grenades, mortar shells, rifle ammunition boxes, and heavy machine gun ammunition boxes.

Old-fashioned Type 38 rifles, Type 99 rifles, Type 92 heavy machine guns, grenade launchers, individual steel helmets, military bayonets, and gas masks are displayed against the wall.

In the corner were piles of old military rations, compressed dry rations, military bedding, medical bandages, and sulfonamide drugs.

Despite being covered in dust for decades, the grand scale of this base in its heyday is still evident.

"Having lived here for hundreds of years, they know the terrain well; they really run incredibly fast!"

Upon entering, Qin Yun immediately lost sight of Ao Bai. He couldn't help but feel a bit emotional. This number one warrior of Manchuria was not only good at fighting, but also quite adept at escaping!

As Liu Yanyan walked through, her heart pounded with fear, and she couldn't help but ask in a low voice.

"Boss, what... what is this place?"

"There's such a large underground fortress deep in the mountains of Northeast China? Could we have stumbled upon some kind of military base?"

"This wasn't built by us, it was built by the Japanese devils back then!"

Qin Yun kept walking, traversing the deep passages, searching for Ao Bai's traces based on his footprints.

He spoke softly, then solemnly recounted this long-buried, dark history.

"If I'm not mistaken, this should be a Class A underground secret fortress of the Kwantung Army!"

After the September 18 Incident, the Japanese invaders occupied the entire Northeast.

In order to consolidate its rule outside the Great Wall, stockpile troops and strategic resources, the Kwantung Army headquarters secretly conducted prohibited human experiments, grafting of evil magic, and research on biological weapons.

Beginning in 1934, tens of thousands of laborers, prisoners of war, and civilians in Northeast China were forcibly conscripted.

It took a full eight years to hollow out countless mountains in Northeast China and build a dense network of underground bases.

This was the case in Yeren Valley, which Hu Bayi and Wang Kaixuan had visited before, and it was also the case in the place Qin Yun and his companion encountered.

"Such secret bases are generally not numbered, recorded, or registered with the outside world, and belong to the top secrets of the Kwantung Army."

During wartime, it was used to store troops and weapons, conduct secret experiments, and transfer supplies.

On the eve of defeat, in order to cover up all evidence of their crimes, the Japanese high command sealed off all entrances and exits, executed all construction laborers and low-ranking soldiers at the base, and completely sealed the entire base underground.

"As luck would have it, the Aobai Tomb where we were before was built right on the top blind spot of this Japanese fortress."

The two layers, Yin and Yang, had remained separate for nearly a century until Ao Bai forcibly broke through the wall, which by chance opened up the connection.

Liu Yanyan clenched her fists, her anger surging within her, and she cursed under her breath.

"Tens of thousands of people's labor! Eight whole years! Hollowing out countless mountains!"

No wonder the project is so sturdy... Those Japanese devils are truly despicable, utterly devoid of conscience, and their desire to destroy our Han Dynasty remains undiminished!

Those bastards, you better never fall into my hands again, or I'll turn them all into zombies!

"That's a great idea, I wholeheartedly support it!"
