Too much oxygen is not necessarily a good thing, and the disciples of the earth master have been drunk with oxygen, dizzy and nauseous, and physically exhausted.

This dark underground world is simply a lost paradise of animals and plants, all kinds of flying insects, flowers and plants are mutated and huge, I asked worriedly: "Ruyun, you say... Will there be any strong nuclear radiation here, these plants are mutated. ”

Liu Ruyun shook her head: "It has nothing to do with that, but... I think of a time on Earth. ”

"A period?"

"Not bad!" Liu Ruyun said seriously: "The Devonian Period, is the paradise of dinosaurs and various ancient creatures, at that time the oxygen concentration of the earth is more than 2 times that of the present, you see those big beetles, one by one as big as a table, they have no lungs, breathing is completely by the back jaw pores, if in the current world, this oxygen efficiency would have died long ago, and only in the Devonian, that kind of 2 times the oxygen content of the environment can survive." ”

"What do you mean? This subterranean world is a marked zone that was left by luck when the two major tectonic plates were piled up, and like Australia, many creatures that were thought to be extinct were retained? I was taken aback.

"Could there be dinosaurs?" Zhang Zhiyan was also embarrassed.

Liu Ruyun said: "It's hard to say, let's observe while walking, Zhiyan, you still give everyone stealth, let's walk in the back, some cunning creatures like to attack the target from behind." ”

She was right, some wild snakes on the side of the road in the countryside, the first person who walked through the tall grass was not attacked, but the one who walked at the back was often gnawed.

I subconsciously looked back and couldn't help but be shocked, we entered this underground world through a tunnel mouth similar to a cave, but when I looked back, the tunnel mouth... It's gone, similar to the space tunnel that I used to travel through.

"Ruyun, we have no way out," I whispered.

Liu Ruyun sighed and nodded: "In this underground world where the space-time tunnel cannot be discovered, it is fortunate that there is still Zhiyan's unicorn eye, otherwise it will be troublesome." ”

Zhang Zhiyan said: "I'm worried about these earth masters now, they can destroy demons and ghosts, but deal with the big insects in this underground world...... These are real creatures, and humans are completely at a disadvantage, and what they encounter now is still mild, but there is a danger ahead of them. ”

"Yes, if they were all Heavenly Masters, it would be better," Liu Ruyun responded.

As soon as she finished speaking, a "bang" gunshot, and a disciple of the Fujian Dragon Seeking Sect not far in front of us had his brain cracked, and his brain burst to the ground!

"Ahh Killed! ”

"There's a gun!"

"Who? Could it be Ye hesitation? ”

......

People are messing around, noisy and shouting, and we are also confused, in this bizarre underground world, in addition to the big grass, flowers and insects, how can there be guns?

"Don't mess around, everyone! Lie down! I use ghosts to move mountains to cover up the reality," Yang Rushui shouted loudly in the front team.

As soon as he finished speaking, there was a series of gunshots, several disciples of the earth master were shot and fell to the ground, and the people in the movie were just a hole after being shot, which was completely fake, these people were beaten to the flesh and blood, and their arms were directly knocked away!

OMG! It's the sound of a machine gun! The machine gun is ringing, I can't imagine ... Could it be that the fake Ye Heist not only led the evil cultists of the White Bone Heavenly Corpse Sect down, but also brought a gun?

Huaxia is forbidden to guns, which... The fake leaves are too wild, not only the exercises are against the sky, the methods are vicious, and even the guns are there!

Layers of stagnant yin qi rose, fortunately, this underground world is not an infinite place, the yin qi is endless, and the yin qi wall built by the ghost moving the mountain quickly surrounded the team of a thousand earth masters.

Under the Yin Qi configuration, the body of the earth masters is temporarily retreating, although it is not as stealthy as stealth, but it can also disturb the opponent's hearing and hearing, so that the opponent cannot identify the target, and everyone is eager to know who is launching the sneak attack.

"Da Da," another string of machine guns rang out, and in the dark "night sky", a bright line shadow crossed, obviously the other party had lost its accuracy and launched an attack on the moving mountain shadow.

"Da Da, Du Tu Du," the machine guns rang out constantly, the light and shadow filled the sky, and we were all lying on the ground, our brains were buzzing, this... This is by no means one or two people with a gun, it is almost like a legion! The people of the White Bone Sect Heavenly Corpse Sect are saving chicken feathers to make marbles, and there are two or three hundred people, are they all fully armed?

They're all armed with zombies, right? My heart was twisted into a knot.

At this time, between the "heavenly pillars" like the high ridge canyon, I heard a faint voice, the tone... It's not Chinese. But it doesn't look like the language of an ethnic minority.

Liu Ruyun's eyes widened, her body trembled, and she muttered: "My God! Could it be them? ”

"Who?" I asked nervously.

Liu Ruyun replied: "I heard the voice just now, it was German. ”

"German? This is too," I suddenly felt that there were Germans in this bizarre underground world.

"Yes, it's German, they told me to stop shooting, I guess I'm going to come over to check on the situation soon, let's be careful," Liu Ruyun said softly.

I have 10,000 question marks in my head to say... In this underground world, there are Tibetans, ancient demon kingdoms, or remnants of Zhangzhung culture, I can understand, how can there be Germans, Germans are 108,000 miles away from here!

"Ruyun, here... Could it be a huge space-time tunnel that connects with Germany in Central Europe? I asked, surprised.

Liu Ruyun shook her head: "It seems... Another historical mystery has been solved. ”

"A historical mystery?"

"Not bad! In 1943, when the defeat of Germany became clear, Hitler and his vassals began to ponder, the sword went sideways, and wanted to use mysterious power to turn the tide of the war, in Europe they studied black magic, and sent a purebred Germanic army of 250,000 to Tibet to find the ancestors of the remnants of Atlantis......"

Liu Ruyun described, ** believes that the ancestors of the Germanic peoples came from an ancient country in the Atlantic Ocean, Atlantis Great West, and later this continent sank to the bottom of the sea, but the disease of civilization did not disappear, and in the depths of the seven oceans and five continents, there is a criss-crossing Atlantis tunnel.

This Atlantis tunnel, in the underground world, connects the world, and the Tibetan Plateau is the meeting point of all the tunnels.

Therefore, they believe that the ancestors must have a highly developed civilization in the depths of the Qinghai-Tibet Plateau, and sent 250,000 troops to explore, find the ancestors, and lead them out to stir up the war.

The former Soviet Union has always suspected that they have built a secret military base in Tibet, but under multiple searches, there is still no trace, but from the military secret materials that broke through Berlin, it was found that there was indeed such a large army, which belonged to the SS of Hitler's lineage.
