This passage is of the same structure as the one outside the blast door, but wide enough for the tank to walk inside. There are bunkers with machine guns along the road, but the people in the bunkers have become a pile of bones. After encountering the undead soldiers, Li Huan and the others were highly vigilant, but they did not encounter any more undead soldiers along the road.

It's just that everyone sighed that in addition to reversing the wheel of history, the Nazis were really advanced in engineering technology, and they had already opened up such a large secret base in the volcanic tunnel under the glacier in that era. Moreover, the facilities in the base are reasonable, and on the way, Li Huan and the others seem to have seen a soldier's living area. Everyone went in to investigate, and everything was rotten except for the metal bed frame and white bones, and the portrait of the mustache on the wall.

"No matter how big your ambition is, you can't beat time......" Li Huan sighed.

Not far from the living quarters, a light suddenly lit up in front of the tunnel, and it was pure white, like the light of an incandescent lamp. Li Huan and the others immediately became alert, how could there be light in a pitch-black underground tunnel?

Li Huan asked everyone to lean back, walked in front of him by himself more than ten meters away, carefully turned a corner, and finally saw the source of the bright light.

It's an underground cavern that's bigger than the hollow outside the airtight door.

This underground cave was better built, and in addition to being wrapped in reinforced concrete, metal supports were put on the walls. And the light came out of a series of light bulbs. Bright light bulbs hang above the sky, illuminating the place as bright as day. Li Huan looked at these bulbs and was stunned, and he didn't hear any generators nearby, where did the electricity to support the lighting come from?

Li Huan was about to go in to check, when suddenly his whole body was agitated.

The muzzle of a black hole, facing the exit of the tunnel, scared Li Huan a lot!

It was an 88 mm caliber anti-aircraft gun, one of the most successful artillery pieces used in World War II.

This was the large and medium-caliber artillery built by Hitler after he finally threw aside the shackles of the arms limitation treaty, which once gave the Allies a nightmare. Although it was originally produced as an anti-aircraft gun, it was best known for its anti-tank capabilities. At that time, the Nazi Panzer Corps took a fancy to this gun and transplanted it to the tank, thus making the tank a nightmare on the European battlefield, the famous "Tiger".

"Damn, no matter how the cannon is here, firing the cannon at this distance is about equivalent to suicide!" Li Huan scolded secretly, fortunately, there was no one to control it, otherwise it would be up to a few of them to break through this tunnel mouth.

After confirming that there was no danger, Li Huan took a few girls forward.

The entrance to the tunnel is made to look like a beachhead, and behind the bunker, there is a structure that looks like a maintenance factory. The repair shop was built of steel bar, with pipes and circuits connected everywhere. The place behind the repair plant is no longer visible, completely blocked from view by this huge plant.

Li Huan didn't take a closer look at what was behind him, because everyone's eyes, including him, were attracted by what was half-assembled in the repair factory.

It was a bell-shaped, sci-fi machine. It narrows and widens from top to bottom, and it looks like a hanging bronze bell. On its body, circles of rivets are neatly struck on its body, and it looks like it has a bit of the evil beauty of a steam machine. The machines were not assembled, and the shells were usually half-bare, filled with several clear glass conduits containing dark red liquid.

"It's the bell of death!" Fiona almost exclaimed.

"Let's go, take a closer look!" Li Huan's expression froze.

The crowd approached the repair shop.

There is no need to look at it, and there is no need to confirm that if there really is a death bell in this world, it is definitely the half-assembled machine in front of you, and its bell-shaped appearance is too eye-catching. The Death Bell is about 12 meters tall and is surrounded by various symbols and descriptions in German. As soon as he approached the Death Bell, Li Huan immediately felt an uncomfortable aura, and after glancing around, Li Huan found that there were more than a dozen skeletons that had turned into corpses near the Death Bell.

These skeletons are different from the skeletons wearing military uniforms outside, and they wear standard white coats and dress up as scientific researchers. This is the deepest part of the Nazi base, everything is well protected, and the corpses are even as if they were dead.

One of them was particularly conspicuous, the unknown scientist's temporary movement was to recline against the Death Bell, holding a pistol in his hand and a large opening in his skull. If he guessed correctly, he should have shot through his own head. Beside him, there was also a small notebook and some scattered data drawings.

Li Huan groaned for a while, picked up the small book next to the skeleton on the spot, and tried to find some clues on it.

The above record is very messy, but from the above content, it is vague to restore what happened before.

Li Huan glanced at it and roughly understood everything, the recorder of this small book, that is, the scientist who pierced his head, was a Nazi. These things were all secretly recorded by himself. The scientists who died were forcibly taken away on the eve of the Nazis' demise, and they were taken from Europe and secretly transported to the base. In the years that followed, they were ordered to work on various apocalyptic technologies.

In the notebook, Li Huan learned that in the first year of coming to the Nazi underground base, the bell of death was indeed successfully developed, and in the second year of the Nazi surrender, the prototype of the bell of death was already operational. It works, as it was originally designed, silently, even in a small area. However, although it was successfully developed, it did not work in the end, because the dark red liquid it used was so rare that it required a large amount of liquid to operate each time.

When the Nazis were in full swing, they could still collect a lot of resources, but in this underground base where birds don't, what if there was a group of genius scientists? No matter how talented you are, you have to refuel to run, otherwise Ferrari can't compare to a van. From this small book, Li Huan can completely see how the Nazis came from the beginning of their ambition to their despair at the end.

"On May 3, 1944, the first day of entry into the base, those stupid Allied troops, thinking that they had seized us, no, the great Führer had taken with us almost all the scientists and the stock of gold, jewelry, and art, and we and the five thousand most elite SS troops slipped away under their noses. Our reserves of talent and technology, as well as what we took away, were enough for us to counterattack three years ago, and the Führer was right, we did not fail, we were only temporarily dormant ......"

"On September 21, 1944, we made significant progress in our research, and the Death Bell had gone through the initial trial operation, and its power was beyond our expectations, and it was all turned into black water after human experiments on soldiers who volunteered to die for their country at half power. Moreover, when it operates, it can open a passage to other worlds, and the Führer has already crossed the passage with three thousand loyal soldiers to another world to find supplies, and once it appears in the world, the course of civilization in the world will be rewritten!"

"May 10, 1945, I don't feel good today, we know that the Third Reich will never fall, but those damn cowards actually signed some kind of surrender agreement! Wait, wait until the Führer brings back the supplies needed, when our supersubmarine is built, we will make the world feel terrified! Long live Hitler!"

Seeing this, Li Huan sneered, this Nazi-led scientist can't be said to be stupid, and anyone who can do a leading project won't be stupid. But the direction he thinks is completely wrong, because those who drive history backwards will be crushed by the wheels of history, not to mention what kind of super submarine he wants to conquer the world. At that time, Citigroup was in full swing, and it was like dumplings under aircraft carriers and submarines, and no matter how super a submarine was, what could it do?

But this content also surprised Li Huan.

The biggest mystery left over from World War II, whether Hitler was dead or not, is solved here. He didn't die, and he took his loyal Nazis to another world Li Huan is a person who has crossed the door of space, and he knows the risks of another world very well, and it is an act of death to cross space at will, as if he opened the door of space by himself, and the domestic high-level is still preparing.

Feel free to cross the space, and don't think about coming back.

Sure enough, when I looked down again, the contents of this notebook were already very sloppy.

Apparently, the Nazi scientific mentality of taking notes collapsed, because their Führer did not return.

And Li Huan found the existence of a suspected dark sun in the notebook.

"On April 17, 1946, word came out that we still had a group of party members moving around, but they were afraid of being arrested, and refused to help us, these damned supernatural beings, sure enough, only science in this world can believe him......! But after all this time, there is still no news from the Führer, and there is not much energy left in the Death Bell. ”

The "supernatural ability" of the notebook should be the predecessor of the dark sun, and this time it is a real hammer. With this little book, don't think about having a good life after the dark sun. The attitude of the whole world towards the Nazis is one, and one less is killed. Besides, if his guess is correct, Bellamy should have already set out to arrest people.

If you look at it any further, it's just some babbling.

"November 18, 1946, damn it, we've been here for more than two years and we still haven't heard anything from outside. The Führer has not yet returned, we are running out of supplies, and all scientific progress has come to a standstill. We need supplies so much, we can't do anything without them......"

"On January 7, 1947, yesterday, the person in charge of the base committed suicide by drinking bullets, and the loyal party members were voluntarily transformed into undead soldiers to enter the dormant chamber in order to keep us alive and complete the final research, so as to reduce the consumption of the base. But it didn't work, we seemed to be stuck in a strange circle, and I felt like we would never get out. ”

In the end, Li Huan turned to the last page.

"December 1949, damn it I can't remember that today is the first day of December, we have run out of all our supplies and we have run out of energy. We've done all the research, and we've got a lot of treasures, but what can we do? I'm going crazy, if anyone comes to arrest us, then just come, I haven't eaten for three days, I'm going crazy......"

"In January 1949, it was over, and there was nothing left of the base except for the electric lights powered by red liquid waste...... Hitler was a liar, a liar through and through, and we have studied everything he wants here, but we still can't escape the fate of destruction, so be it......"

When Li Huan finished reading the contents of this notebook and roughly told everyone about it, everyone was silent for a while.

I didn't expect that the technology of the Nazis had advanced to this point, but fortunately, the Allies moved quickly, otherwise it would be hard to say whether the historical course of the war would have been rewritten.

"This thing...... Shouldn't you stay in the world, right?" Shangguan Qing was the first to put forward her opinion: "It's okay if you can transport it back to your superiors, but it's a little difficult to transport things back to China from here." ”

"It is true that there should not exist in the world. Li Huan nodded: "It's too dangerous, if it weren't for the lack of energy in that red liquid, it's really hard to say how it will develop in the later stages of World War II." No wonder Darksun wanted this Death Bell so much, it could open a door to other dimensions, it was full of infinite possibilities, and its lethality was so terrifying. ”

"Blow it up!" Sivir suggested.

The three of them looked at each other and felt that it made sense, as soon as they saw the Death Bell, Li Huan asked Xiao Fei to draw a diagram of the structure of the entire machine, and even Xiao Fei had to admit that these scientists were indeed geniuses. With such a simple technology and such a high degree of system integration, a "Star Gate" was finally created, and the name Star Gate was installed by Xiao Fei, and it was also something that had to be destroyed in Li Huan's special reward mission.

Only Fiona was a little embarrassed: "Master, such a powerful machine, there may only be such one, you really want to destroy it?"

"Won't you destroy it and keep it for the New Year?" Li Huan smiled faintly: "Don't forget your identity...... You've come to look for the Death Bell, and now you've found it, you've seen it, you've touched it, do you still want to move back home?

"I'm ......" Fiona muttered to herself in a low voice for a long time, still a little reluctant: "This is a super machine made by skipping a grade in advance in human history!"

"Shangguan, blow it up. Li Huan no longer talked nonsense with Fiona, he can now see that this vampire is really not too bad, but he has plunged into the "ocean of knowledge" and gone the wrong way. When this trip is over, it is not impossible to return the blood of the Origin to her.

However, Shangguan Qing spread his hands: "No, a lot of explosives were used to blow up the passage, and blowing up the airtight door was the last thing left." ”

This is embarrassing, Li Huan doesn't have enough explosives in his hands now. If you want to blow up this big guy, you need at least about two kilograms of C.4. Could it be that it will become a point of explosives and then open a space passage? Li Huan glanced around and fixed his eyes on the 88-millimeter guns at the mouth of the tunnel: "Come, isn't this a ready-made one! Although it has been released for several decades, there will always be a sound of so many shells!"

Just do it, at the moment Li Huan returned to the 88mm gun, this kind of artillery has a 360-degree firing range, and it is right to adjust the runner. After Li Huan adjusted the firing range, he took out a box of shells from under the 88mm gun, checked them one by one with mental power, and sure enough, he found a few fuses with intact structures. The ammunition here is also divided into many categories, there are white-headed armor-piercing shells, red-headed high-explosive shells, and against the Death Bell, it must be high-explosive shells. Li Huan put in the ammunition, Shangguan Qing adjusted the shooting of Zhu Yuan, Li Huan took one last look at the Bell of Death, and said, "Bye-bye." ”

Then he pulled the leash.

Bang!

This was Li Huan's first time firing a cannon, and it felt like it was indeed far from shooting, and the huge vibration shook his heart. The 88-mm high-explosive bomb was excited by the huge energy, came out of the disembowel, pulled a long tail of smoke, and slammed the death bell. The Bell of Death may be high-tech, but when it comes to thick skin, it is far less than heavy armor such as tanks, and it is also a target with a thin skin and big stuffing.

"One more shot!"

The second shell hit exactly where the Bell of Death was shattered, causing a chain reaction that blew the Bell to pieces. The 88-mm cannon was placed behind the cement-cast fortifications, and several people dodged the explosion with this fortification. At this point, the Death Bell completely disappeared from this world, and the Nazis' hard work was reduced to powder under the two shells.

The energy source in the system mission should refer to this death bell, right?

Everything has been blown up, why isn't there a hint of mission completion?

Sure enough, the reward tasks released by the system are not so simple, can't they be easily completed by me?

Li Huan was sighing, and suddenly, a shock spread in the underground space. With this strong vibration, the system began to sound a warning tone frantically.

"Warning! Warning! Unstable space discovered!"

"Detection is over, space is about to open!"

After the Death Bell exploded, a distorted space appeared at the location of the explosion, and this distorted space was different from Li Huan's stable spatial channel, and it was impossible to guess where it would lead behind. Soon, the distorted space turned into a "door", and from behind the door an uncomfortable aura erupted, enveloping the entire underground space.

This layer of aura has a faint reddish, and through this layer of breath, it seems that everything becomes blurred. The incandescent lamps that had been on for decades and hung on the ceiling of the underground space were shrouded in this breath, and they seemed to become listless, and the lights began to flicker, like the opening of a horror movie. The red aura spread extremely quickly, enveloping the four people in it, and suddenly, the four of them felt that the original clear line of sight, as if someone had installed a frosted glass in front of them, and even the companions who were close at hand turned into a halo-like weirdness.

Everything has lost its sharp silhouette, everything is blurred and distorted.

The three girls, including Fiona, had seen this kind of thing for the first time, and the three of them couldn't help but be stunned on the spot.

In the end, it was Shangguan Qing who reacted: "What was written in that notebook, did you go out of this underground base with 3,000 soldiers and never come back? Could it be that you blew up the Bell of Death and got them back?"

"There's this possibility. After Li Huan finished speaking, he reacted, this is the unstable energy mentioned in the reward task.

"It's not like the breath of a human being. Fiona felt it for a while and added, "I don't feel angry." ”

"Most of those Nazi soldiers have been gone for decades, or have they been trapped somewhere? After being trapped for decades, do you still expect them to be human?" Li Huan didn't know why, and suddenly thought of Bellamy's little skeleton: "Sivir, you and Shangguan look for weapons that can be used nearby, and prepare ammunition." Fiona comes with me, and we're in front. No matter what was in the door, what they were going to do when they came out, they couldn't let them succeed if they wanted to pee out...... It's going to be a tough battle, and everyone is ready. ”

The spatial passage formed by the distorted space was still spewing mist outward, and the mist was soon mixed with all kinds of whisper-like whispers, which disturbed people's hearts.

"There are a few MG42s that can still be used, and two 88mm guns are available!" Shangguan Qing and Xavier were the weakest in combat, so they were arranged to control their weapons in front of the trench at the entrance of the cave.

Suddenly, the incandescent light hanging on the roof of the cave flashed twice, and the entire space turned blood-red. A black substance as thick as dry ice began to flow from the distorted spatial passages, and the murmur turned into a roar.

"Shangguan, fire a shot and try it. Li Huan pointed to the space passage.

Shangguan Qing did not hesitate when he heard this, pushed a cannonball to close the bolt door, pulled the fuse to launch it, and suddenly the cannon fire rang out. A cannonball that was so fast that it couldn't be seen clearly slammed into the spatial passage with a powerful energy. The cannonball shot into the space channel without hindrance, and a trace of electric arc seemed to erupt from the space channel, and the arc disappeared after jumping on the ground five or six times, and soon, a smell of blood came from the space channel.

Fiona subconsciously licked her lips: "Master, something is approaching us." ”

As soon as she finished speaking, the floor of the cave hall began to tremble slightly, and then Li Huan heard a chaotic number of footsteps and piercing screams approaching everyone from the darkness not far away.

"Your task is mainly to protect Shangguan Qing and Xiwei. Li Huan pulled out the mace from the virtual space and began to code his thugs.

Wealth, wealth, reefback turtle ......

Finally, the source of the screams in the underground hall appeared Shangguan Qing guessed correctly, it was the Nazi soldiers who had crossed the spatial passage to another place and never returned. It can be seen from the uniforms on their bodies. They wore steel helmets, carried water bottles, combat rations, maps and ammunition belts on their backs, carried submachine guns on their chests, and had Nazi crosses on their arms.

But they can't be called "human" anymore.

These guys don't know where they have crossed, they should be infected, and one by one they have become sharp and ugly, and they don't look like people. And their IQ is even lower than that of those undead soldiers, and the gun on their chest doesn't know how to use, but their eyes are blood-red and they are approaching the few people inside. However, these "people" have a low IQ, but the number makes up for the IQ gap, not only on the ground, but also in the sky, some winged guys have appeared, and they surrounded the four people from all directions.

"Hit!" Li Huan said cleanly, then picked up his mace and rushed into the monster crowd with two fast-moving thugs. The reefback turtle was left by Li Huan and placed in front of the bunker to block the fish that slipped through the net.

The "people" who suddenly appeared were obviously enraged by Li Huan's actions, and hundreds of monsters wearing Nazi military uniforms were densely packed, directly drowning Li Huan like a fierce tide. But this doesn't have much effect, the monster is too fragile, it seems to be a ghost thing that a person loses consciousness after being infected, as long as he is hit by Li Huan's mace, his muscles and bones will be shattered on the spot.

Not to mention the offensive of Wangcai and Fugui, Wangcai simply developed a new tactic of lazy donkey rolling after discovering that these guys were weak.

It turned into an eight-meter-long combat form, rolling around on the ground and crushing, and the guy who was crushed by it immediately lost the ability to resist.

Although there were many infected Nazi soldiers, they failed to take advantage of it at all, Li Huan and the two thugs were overwhelmed by a huge number of opponents, but just like sheep and tigers, no matter how many sheep there were, don't want to take advantage of tigers. Later, Li Huan even felt as if he was playing a game of whack-a-mole, and the number of Nazi soldiers who had turned into monsters was so large that he overshadowed the sky, but he was a little misunderstood, and there were still some doubts.

It's that weak?

After crossing the space, after completing the transformation from a human to a monster in an unknown space, it is so weak?

In addition to the weakness of the opponents on the ground, those with wings in the sky are even weaker, and the air flow brought by Fiona's wings can make a large area of enemies lose their balance, fall from the air like dumplings, and after falling to the ground, they suddenly become blood gourds, and they don't move.

Totally unreasonable, too weak!

Of course, Li Huan also found a problem, these weak guys did not come out of the space channel, but crawled out of the unstable and distorted space left and right of the space channel. After Li Huan smashed the steel helmet of a Nazi monster, he communicated with Xiao Fei in the spiritual power channel: "What the hell is going on? The space passage is open, and they don't crawl out of the space passage, but appear from the surroundings, and they are too weak!"

"I also discovered that because this spatial passage is unstable, there may be 'infiltration' around it. Just like a faucet, a good quality faucet can only be waterproof from the switch, and the engineering quality is a little worse, and the water begins to drip from the seams. Don't be too happy, since there is a door, something will come out behind it. Xiao Fei reminded Li Huan.

After discovering that these monsters were very weak, Sivir also joined the army of bandits, her cultivation was completely inadequate in Li Huan's eyes, but it was enough to deal with small monsters. After Xiwei went out to fight, the guns on Shangguan Qing's side also rang out, and the monster army, which was already very weak, was wiped out in a short time under the joint attack of the four and Li Huan.

The cave hall was bloody.

"Is this the end of it? This is the elite of the Third Reich across Europe?" Li Huan shook off the blood stains on the mace.

"It's too weak. Everyone nodded.

The three thousand soldiers recorded in the notebook have not returned after passing through the space passage, and after Li Huan destroyed the death bell, he accidentally opened the passage for them to return, but now half of them have turned into monsters and fallen into the underground hollow. Just when everyone felt that the so-called Nazi Doomsday Army was completely unworthy of its name, the spatial passage changed. It went from being distorted and blurred at the beginning to being like substance, turning into a dark red door.

From the door, there is an oppressive atmosphere.

The people looked at each other, and the Lord came out.

Li Huan moved the reefback turtle to the front, and then said, "The main one is coming out." ”

"What else can come out, it can't be Hitler's resurrection, right?" Shangguan Qing had a big brain: "I used to play a game called "Return to the German Castle", and there is such a bridge in it......"

The color of the gate became darker and darker, and there were bursts of sad music coming from inside, Li Huan couldn't help frowning: "It's a little ugly, like mourning, Hitler is unlikely to appear, but he must be a powerful character." ”

Just when Li Huan and Shangguan Qing were talking nonsense, two bloody hands suddenly stretched out from inside the gate, pulling the "door frame" and struggling outside. But in an instant, most of the things in the doorway were exposed. If the Nazi soldiers in front of them cannot be considered "people", then this thing is certainly not people. What came out of the doorway was a big goat face and a pair of terrifying horns, and the purple-red skin was pimpled like a toad, and when it exhaled and inhaled, it had sparks in its mouth.

"Demon!" exclaimed Sivir, "this is a real demon!"

"The Führer really mixed it up when he arrived, and tried everything to win. Li Huan's eyes froze, but his mouth was disdainful: "In terms of appearance, our Chinese monsters are still good-looking, why do your monsters look so cruel." ”

The most terrifying thing is that Li Huan can't tell its level at all, which means that it has passed the stage of four layers of crushing, and this monster is at least four levels higher than himself.

"Master, don't be kidding, the real demon is not something we can resist, we better leave immediately!" Fiona reminded.

"We can't run away from this thing, but I still have a way. Li Huan's eyes froze: "Shangguan, aim and hit hard, suppress it in the passage, even if you can't kill it, suppress it, give me a minute!"

"Listen to you!" Shangguan Qing had a blind trust in Li Huan.

Rumble!

The sheep-headed demon suddenly exploded violently, and an 88mm cannonball shot straight into its body. But when the smoke cleared, everyone was shocked to find that this monster had no scars on its body at all!

It was the best artillery gun in World War II, and it was fired directly at a distance of more than 200 meters, and there was no scar at all!

Li Huan's judgment was right, it was very strong, once it broke free from the spatial passage, none of the people present could run away, and this physical strength was about to catch up with the reefback turtle. Of course, the reefback turtle is nothing but hard, and this sheep-headed demon is not a vegetarian except for its amazing physical strength, judging by its breath.

"Xavier come here to help!" Shangguan Qing hurriedly shouted, "You use another one!"

Shangguan Qing said as another armor-piercing bullet fired, and Sivir also returned to the trench, taking control of another 88mm gun, and the two began to bombard the monster indiscriminately. In just a few minutes, the two of them fired twenty shells, which caused the sheep-headed monster to roar in anger. Of course, everyone can also see that this monster was bombarded indiscriminately by the cannonballs, and there were no scars on the surface of the body, and the powerful cannonballs did not have any substantive effect except for "pressing" back part of its body.

But this is what Li Huan wants.

It is true that this monster is very strong, but as long as he doesn't come out in the space passage, Li Huan has a way to clean it up.

He's going to destroy this spatial passage directly.
