"Arsenals, abandoned military factories during World War II?" Although Li Ling had a lot of speculations before, such as chemical factories, heavy machinery factories and even biochemical research institutes, etc., he couldn't guess that this was a military factory during World War II.

And military factories often only serve the military, providing the military with supplies.

"Yes, this area is the area invaded by the Orientals, and in the past, a capitalist of their country built a reserve military factory in this valley, which provides all the armaments, including ammunition, guns, and light portable weapons!" The indifferent woman led the way, and as she walked down the stairs, she could only hear the voices of two people echoing crisply in the corridor.

If that's the case, then be able to spot the mysterious man here? It's even more difficult, and this person at least has the ability to hide from the military, the Chinese Security Bureau, and the Intelligence Bureau.

Now, Li Ling can only guess from two aspects, on the one hand, this is a World War II military factory that has been discovered and protected by the state, and a secret base has been built under this factory to develop some advanced weapons, and on the other hand, here is a capitalist with great strength, investing heavily to engage in some research that needs to be kept away from the crowd, just like the umbrella company in Resident Evil!

"That'...... What's going on with you in this underground passage? What is your purpose? Li Ling felt that this kind of tunnel, to dig out, the difficulty is so great that it can be compared to the moon landing. Those who are with the indifferent woman definitely have some kind of purpose here.

Li Ling pointed to the brightly lit staircase tunnel.

"That's a question within the limits, and I'm not going to answer it." The indifferent woman said.

Li Ling shrugged helplessly, knowing that it was not so easy to get an answer, so he had to carefully observe this corridor, which is a vertical spiral rotating descending ladder, which can reduce a lot of unnecessary drilling, as long as a deep pit can be drilled at a time to achieve the desired effect.

After walking a few dozen meters deeper, Li Ling gradually saw some magical things that you would never see in your lifetime.

On the gray walls, there are mysterious and misshapen patterns carved into them, as if they were some kind of code and summoning from ancient times.

In this magical character code, there are some even more magical creature patterns.

These magical creature patterns have different shapes, and, as far as Li Ling can see, the creatures on these creature patterns are extremely weird, and they are definitely not species that can be born on the earth.

"These ...... Carve. The more Li Ling looked at it, the more frightened he became, and he couldn't close his mouth in surprise, these magical creatures carving, these carved lifelike monsters, were something that Li Ling couldn't recognize.

Take the pattern of one of the creatures on the wall, one of the creatures is very strangely shaped, like a black soft mud, but the mud is covered with strange elongated antennae, and on these slender tentacles there are magical green spots, and those spots are very similar to an organ, which is the eye.

In other words, there are countless eyes on this mud! With the human mind, it is impossible to imagine what kind of creature this would be!

"These carvings were left by the people who built the military factory here, and this tunnel is more than 60 years old." The indifferent woman said.

"And what are these creatures so famous for?" Li Ling looked at them one by one, and the countless creatures on those walls made Li Ling unable to believe that in this world, in addition to the creatures he knew, who else would carve these strange creatures in this corridor.

"I don't know what to do." The indifferent woman didn't lie, perhaps, she really didn't know what to do. At least Li Ling's cognitive range is unable to accept these creatures.

"The man who built this military factory carved these creature patterns in the first place." Li Ling asked.

"After translating the ancient text on this wall, we can know that this is to record the totem!" The indifferent woman said.

"Record Totem!!" Li Ling frowned.

"Totems are often imaginary artifacts of human beings, which may not exist in real life, but whether they really exist or not, not necessarily this word, sometimes scientists themselves use it is a bit far-fetched." The indifferent woman said.

"For example, the dragon in China, the dragon is a totem that China has worshiped for thousands of years, we often say that we are the descendants of the dragon, but the dragon is a totem, has it ever really existed? I guess no one can answer. The indifferent woman said.

"At least I haven't seen it!" Li Ling shook his head and smiled.

The dragon has the meaning of totem in ancient times, whether it is on the stone pillar of the palace of the imperial city, or on the dragon chair, and various sacred places, you can see the totem of the dragon, the appearance of the dragon, and it is also portrayed lifelike, as if it were a real thing.

But do dragons exist?

Li Ling shook his head, trying not to fall into the whirlpool of this question, and the most important thing is that the atmosphere of the corridor here is very mysterious, so that Li Ling gradually believes that these magical totems are real.

"Here we are." The indifferent woman took Li Ling and finally walked to the lowest end of the corridor.

At the lowest end of the stairway is a fifty-square-meter space in which there is nothing but an iron door with a combination lock.

The indifferent woman walked to the combination lock with Li Ling, and quickly pressed out a series of numbers, which were at least thirty digits.

Moreover, the setting password in this combination lock is changing according to a certain formula, that is to say, every other day, this password will be changed into another password according to the formula of that variable, this kind of high-end technique, Li Ling has seen it, but what Li Ling has seen is only seven, but there are thirty here, which is surprising to think about.

"You're so smart, you can calculate the thirty-digit change password and the formula change so quickly." Li Ling's words of admiration are true.

"It's over, no one here is an ordinary person." The indifferent woman said lightly.

After entering the password, the door opened slowly with a click, the door was made of alloy steel, ordinary armor-piercing bullets may not be able to penetrate, and most importantly, the thickness of this door was almost more than one meter.

What kind of research is needed to require such a high-intensity defense system, which makes Li Ling shudder.

If this person who invited him had evil intentions, even if there were ten Li Ling, he would not have a chance to live, a person who could make such a powerful defense system, and his subordinates were all first-class talents in the world, wrapping killers.

"You follow me for a while, if you lose it, you may never be able to get out." The indifferent woman said.

"For what?" Li Ling still wanted to ask clearly, but the indifferent woman just angrily pouted at Li Ling and pointed to the inside of the mechanical door.

Inside, there is a wall, and there are passages next to each wall, and, as far as Li Ling's common sense goes, there is an entrance next to this wall, and behind this is a labyrinth.

Oh, my God. Someone has built an underground labyrinth underground!
