"Is this the lair of that Yuankou Monkey King? How does it look no different from our human home? Stepping into the water curtain cave, a somewhat dilapidated scene appeared in front of Gu Han and the others. Pen, fun, pavilion www. biquge。 info is just different from the imaginary dirty cave full of all kinds of disgusting corpse residues and bones, this water curtain cave is actually a daily home.

Large and comfortable double bed, lamps all over the ceiling, a 100-inch super large TV, soft and comfortable sofas, etc., all the furniture and items that a normal person should have are available in the water curtain hole, which is not like a monster's residence at all, but it is no different from a normal human house.

"Be careful! This is the lair of demons and monsters, and thunder and lightning circles are placed everywhere, and if you are not careful, you will be attacked by thunder and lightning circles. You must find the core of the entire circle and destroy it to ensure safety! The first time he entered the Water Curtain Cave, Song Hama said very nervously.

"That's the core of the circle you're talking about?" Gu Han glanced around the entire water curtain hole, and then pointed to a cabinet in the corner of the wall, from which a lot of wires were connected.

"That's right, that is the core of the thunder and lightning array, this core contains extremely powerful chaotic qi, once touched by these chaotic qi, we won't be able to die in a few months!" When Song Hama saw the core of the magic circle, his whole person collapsed, like a cat with fried hair, and the spirit of the whole person was concentrated to the extreme.

"This is not the core of the thunder and lightning array, it is clearly a nuclear fuel cell!" Gu Han saw Song Hama's nervous state and said with a wry smile. This small nuclear fuel cell is obviously the power source for the entire water curtain cave, supplying power to the electrical equipment in the water curtain cave.

As for what was attacked by the lightning array, most of them were accidentally touched by the exposed wires and were shocked.

Nuclear fuel cells are a technology developed by mankind before the Great Collapse. And because of Yuankou, thermal power, hydropower, wind power and other conventional power plants can not operate normally, so the only way to vigorously develop nuclear power is to vigorously develop. When Yanjing City was built, small nuclear fuel cells were already being produced.

It's just that with the continuous progress of black technology, small nuclear fuel cells have withdrawn from the stage of history, and all have turned to the use of micro nuclear fuel cells, and if you want to see such small nuclear fuel cells in reality, it is estimated that you can only go to the museum to find exhibits from 800 years ago.

Through these discoveries, it can be fully proved that this is by no means the lair of the Great Sage of the Demon Clan, it is clearly a human home, but why a human home has become Yuan Kou and the Great Sage of the Demon Clan in the mouth of the Heavenly Court, which makes Gu Han's heart can't help but have some doubts.

"Gu Han, come and take a look, there seems to be a mobile phone here!" Liu Nian said excitedly beside the bed, Gu Han walked over, and sure enough, he found an antique mobile phone hidden under the pillow at the bedside.

With the invention of the personal terminal more than 700 years ago, the mobile phone has been completely eliminated from human society, and if you want to see the real thing of the mobile phone, in addition to looking for it in the ruins outside, you can only look for it in the museum.

"This is by no means a mobile phone before the Great Destruction, but a banana brand mobile phone produced by humans after the Great Destruction!" Gu Han took the mobile phone in his hand, flipped directly to the back of the phone, saw a banana-shaped icon, and said decisively.

"Hmmm! I've also heard that the banana brand mobile phone was born after the big break, and there was no such brand before the big break! Rin nodded and said.

"Look at the interface of this mobile phone, it actually uses an optoelectronic interface...... It seems that this should be a mobile phone produced during the replacement of mobile phones and personal terminals, and the earliest mobile phone was produced 180 years after the Great Collapse! Gu Han looked at the optoelectronic interface of this mobile phone and said thoughtfully, all the evidence here points to one point, that is, this water curtain cave should have been established 800 years ago, and the humans living in this water curtain cave are obviously also human beings 800 years ago, at least 800 years ago, this copy of the world is in line with the real history of mankind.

"Wait...... Solid cold ...... If the interface of this mobile phone is an optoelectronic interface, then can our personal terminal be ......" Before Rin's words were finished, Gu Han already understood what she meant.

Optoelectronic interfaces are the most suitable fast interfaces for personal devices, so even after 800 years, the interfaces on personal terminals are still optoelectronic interfaces. If this mobile phone also uses an optoelectronic interface, then with the excellent analysis ability of the personal terminal, it may be possible to read some crucial messages from the memory of this 800-year-old mobile phone!

Just do it! Gu Han immediately controlled his personal terminal to shoot out a photoelectric connection line into the mobile phone, and began to read the information in the mobile phone memory.

Surprisingly, the inside of this mobile phone is quite well preserved, and the personal terminal has successfully read a large amount of data without any effort, although most of these materials are useless and discarded materials, but in the end, Gu Han accidentally found an electronic diary among these materials.

Although the owner of the mobile phone does not write diaries every day, he writes one or two more or less every week, and by reading these diaries, the background of this copy world gradually plumps up in front of Gu Han.

Just like Gu Han guessed just now, this copy world has been a world under normal history from the beginning of the Great Collapse to about 180 years, and the abnormal situation started from the appearance of a large-scale dimensional crack, and almost the entire Heavenly Court's Yuan Kou entered the human world through that dimensional crack, and the Heavenly Court had five Desolate Yuan Kou and dozens of Celestial Yuan Kou overnight.

So Heavenly Court began to strongly integrate other Yuankou forces to attack the human Yanjing City, and finally the dimensional wall protection system of Yanjing City was defeated, Yanjing City was breached, and most of the human beings became prisoners of Heavenly Court, and only a small part of the sword-wielders escaped, and began a career of hiding in Tibet for 30 years.

And after defeating the human race, the satisfied Heavenly Court did not focus on killing the remnants of the human race, but instead set a trap to sneak attack the other Yuankou forces, and finally the Heavenly Court won again, and the main forces of the other Yuankou forces were also exterminated by the Heavenly Court, and this earth became a situation where the Heavenly Court forces were the only one.

In order to cut the grass and eradicate the roots, Heavenly Court began to launch round after round of extermination wars against humans and Yuankou, and under the coercion of survival pressure, the remaining humans and Yuankou were gradually integrated together, which has to be said to be a great irony.

With the sweep of Heavenly Court, the remnants of the human race and the Yuan Kou are getting weaker and weaker, in order not to fall into the situation of sitting on the ground and waiting for death, it is impossible for the human and Yuan Kou to decide to unite all the Emperor Sword level sword bearers and the Wild Rank Yuan Kou of the two forces to launch a sneak attack on the Heavenly Court, as long as they can kill two or three Wild Rank Yuan Kou, then the human and Yuan Kou will be able to launch a counterattack.

He was unanimously recognized by both sides, and both sides also contributed all their remaining cutting-edge strength, among which the human race had two Emperor Sword level sword holders, and Yuan Kou had four Wilderness level Yuan Kou, a total of six top powerhouses.

They first created the illusion of being active in the Americas, attracting the three Heavenly Court's Desolate Primors to the Americas, and then launching a surprise attack on the Heavenly Court.

The diary came to an abrupt end here, because the owner of this diary was none other than the Qi Tian Sword Emperor, one of the two remaining Emperor Sword level sword holders of the human race, and this Water Curtain Cave was where the Qi Tian Sword Emperor lived in seclusion.

At this point, Gu Han finally roughly understood the background of the story of this copy.

This copy is indeed a world completely occupied by Heavenly Court, human beings have been brainwashed by Heavenly Court to become tools of Heavenly Court, and the people who rebelled against Heavenly Court at the beginning are estimated to have all been slandered by Heavenly Court as demon beasts and Yuan Kou, this is really a brain-opening copy world.

As for the outcome of the battle, it is not written in this diary, but from the reality that Gu Han saw and the story of the havoc in the Heavenly Palace in Song Hama's mouth, it can be guessed that the raid must have failed, and the six human and Yuan Kou rebels were also slandered as the Seven Great Saints...... It's just strange that there are only six people, how did they become the Seven Great Sages in the end?

"Gu Han, do you think this is the peach tree?" When Gu Han was reading this diary, Liu Nian Rin also made a new discovery in the Water Curtain Cave, and she found a tree trunk in a corner of the Water Curtain Cave that had been stripped of all the branches by Xue, leaving only the main trunk...... The first time he saw this trunk, Liu Nian Rin thought of their original purpose and found the peach wood that was snatched away by the Monkey King Sword Emperor back then.

"That's right! This is the peach! Gu Han looked at the texture of the trunk and found that there were thousands of circles...... This is definitely an ancient tree that has lived for thousands of years, and what else can the ancient tree that has lived for thousands of years in this water curtain cave have anything other than peach wood!

"Close!" Gu Han stroked the trunk of the peach tree, and the peach wood was directly put into the dimensional pocket, and the three of them searched in the water curtain cave again, and after finding that there were indeed no other valuable clues, they took Song Hama to leave here.

"I'm going to light the fire!" Hearing that Gu Han and Liu Nian Rin were leaving, Song Hama immediately said, and at the same time took out a lighter from his pocket, preparing to burn one of the water curtain holes.

"What are you doing here??" Gu Han saw Song Hama's movements, slapped the lighter in his hand, and asked sharply.

"The rules of the Heavenly Court...... When you meet the residence of the demon clan, you have to burn it clean! Song Hama said at a loss.
