In just one hour, the Shiganshina District was completely occupied. Less than two thousand people retreated into Wall Maria. The rest died either in accidents or in tramples, but more were devoured by the giants. Finally, it turned into a ball of flesh wrapped in mucus and spit out. "Anani, you take Jack and the others to meet Lin Yijing and others inside the Wall of Maria. I have some things to do, and then I will go find you." Anani has become accustomed to following Xu Mo's orders during this time. Without asking why, he immediately took Jack and others away. Although the gate of Wall Maria was closed, it could not stop these awakened ones who each had a [three-dimensional mobile device]. After Anani and others left, Xu Mo briefly identified the direction and ran towards the northeast of Xiganshina District. After killing several giants who blocked the road without opening their eyes, Xu Mo jumped down from the roof and landed firmly in front of an ordinary house with an ordinary appearance. The home of Alan Yeager, the male protagonist in the original work. In fact, ever since Xu Mo learned the address of Allen's house, he has always wanted to come here to explore the basement that is said to hide the biggest secret in the original work. However, judging from the plot of the original work, Allen's injection of the giant potion happened to happen in After the Wall of Maria was breached in 845, he suppressed his curiosity and did not interfere with the normal life of the Allen family to prevent unpredictable changes in the plot. At present, the outer city gate has been destroyed months in advance. Regardless of whether Allen's father has completed the giant potion, with the fall of Shiganshina District, this is already an irreversible reality, and there is no need to worry about the original plot. The impact caused. One corner of the house is somewhat damaged, but the whole thing is still intact. Obviously, the incident in the original work where the male protagonist's mother was devoured by a giant did not happen. The furnishings in the room are messy, and the ingredients that haven't had time to be cooked are scattered on the floor. It can be seen that Ai The Lun family fled in a hurry. Xu Mo walked around to the small wooden cabin next to the house, which was the entrance to the basement. He effortlessly broke the rough iron lock, and the slightly musty humid air rushed in from the dark passage below. Just in case, Xu Mo put on the [Ice Abyss Demonic Armor] and carried the [M1L1 Triple Pulse Gun] carefully down the slippery steps down the passage step by step. There is only a space of less than ten square meters under the steps. There are some farm tools and repair tools piled inside, as well as some junk such as barrels and boxes. It looks no different from ordinary people's utility rooms, and neither does Xu Mo. See anything related to giants. "Strange, even according to the guesses of the truth kings on the Internet, this basement is Allen's father's secret laboratory. There should be some bottles and jars and other experimental utensils, right? Moreover, the Shiganshina area fell so quickly. Even if Allen's father could transform into a giant, he would not be able to completely destroy the corpses and traces No! Xu Mo suddenly remembered that in the original work, Allen's father gave Allen a key to the basement that was said to be, and what sealed the basement was just an ordinary wooden door. An adult with a little strength could use a An ax can break it open, so why do you solemnly emphasize that Allen must keep the key? The only explanation is that the key in Allen's hand does not open the iron lock outside, but there may be another door. The entire basement was not large, and Xu Mo quickly noticed an uncoordinated wooden tool rack in the corner. Sure enough, after moving the wooden tool rack away, a rusty iron door appeared in front of him. In this world inside the wall, iron represents currency in a sense. Even the rich people use only iron-clad wooden doors, but such a heavy and thick iron door appears in an unattended basement. , has to make people suspicious. An ordinary thief would be helpless when faced with such a solid iron door that was at least five centimeters thick. However, this level was meaningless to Xu Mo. He used the ice crystal sword as a lever and gently pried it open. Then he stretched and broke the lock cylinder that was two fingers wide inside. It is still pitch black behind the iron gate. Even if you turn on the night vision function on the [Ice Abyss Demonic Armor] faceplate, you can only see a narrow passage that continues downwards and you don¡¯t know where it will eventually lead. Although the [Devil Sense] did not indicate the existence of any danger, Xu Mo still did not dare to be careless. He picked up the [M1L1 Triple Pulse Gun] and paid careful attention to the surrounding movements, and quietly entered the passage behind the iron gate. This passage seems to be naturally formed, but it should not be so wide originally. There are obviously many traces of manual excavation in some places, and there are many simple steps dug under the feet. Judging from the appalling quality of the construction, it should be a person. do. Continuously go down along the winding passage for aboutAfter walking for more than a hundred meters, Xu Mo began to hear the faint sound of running water. After continuing for several dozen meters, his eyes suddenly opened up. An underground cave the size of a small gymnasium appeared in front of him. An underground river came from a few meters below. The water was rushing past ten meters away, and the water was extremely fast. What shocked Xu Mo was not the unique cave here, but that on the other side of the cave across an underground river, there was a silver-white metal door several meters high. Judging from the simple shape full of technology, it was obviously not It can be manufactured with the current level of metallurgy in this world. There was a narrow path on the edge of the underground cave that led to the opposite side, but Xu Mo didn't want to go far away. With the help of the grappling hook rope around his waist, he jumped and landed steadily on the metal platform dozens of meters away. Judging from the password input device next to the silver-white metal door in front of us, everything here is definitely a product of modern technology. However, it may be because the power supply has been lost after a long time, and the door has automatically become open. state. No wonder no one can explain how the world's low level of technology can create such heaven-defying equipment as a three-dimensional mobile device. It turns out that it's not that someone has come up with black technology, but that the level of technology in this world is already so high. However, a large number of them were lost due to some unknown reasons. It is very likely because of the giant disaster a hundred years ago. This silver-white door seems to be an emergency exit. Its interior is connected to a white passage that seems to extend in all directions, but most of them have collapsed. It seems that a quite tragic explosion has occurred here. Being able to enter the room must have been explored by Allen's father. Xu Mo did not do that useless work and just followed the footprints on the dust on the ground, finally stopping in front of a circular explosion-proof sealed door. It can be seen from the door that is nearly two meters thick that this room has obviously been specially reinforced. It is probably because of this that it was able to be so well preserved in the big explosion. In the room that was as big as two basketball courts, apart from four boiler-like iron cans, there were only some large fixed instruments similar to operating tables. However, on the experimental table on one side, Xu Mo found a lot of test tubes. Such glassware and even a microscope should obviously be the place where Allen's father studied medicine. In the corner of the console, Xu Mo found a somewhat yellowed notebook, which recorded a large number of experimental records and formulas, but most of them were incomprehensible professional terms and symbols, which may not be understandable to some people in this world. It was a treasure, but it was completely useless to him. In addition, Xu Mo also saw a very strange sheepskin map on the wall next to the experimental table. There were two landmasses on it. There were predatory giants and escaping humans on the land on the left, and there was an ocean in the middle. There are many ships floating on it, and there are three walls on the far right land, where people cultivate and multiply and live happily. There are many seemingly decorative patterns on the map. If you look closely, you will find that they seem to be some kind of special writing. However, there is no need for Xu Mo to study it. Someone has already written it on the bottom with a quill dipped in black ink. Got the translation. ¡ª¡ªHuman beings were helpless against the overwhelming fighting power of the giants and had to immediately set out to sea for a new world. ¡ª¡ªAt this time, most of the human beings have died, but most of them are caused by human beings. ¡ª¡ªThose who lost their homes due to the appearance of the giants and fled in all directions, only a few powerful people were able to board the ship. The navigation process was extremely difficult, and about half of them were lost before they reached their destination. ¡ª¡ªThere are already powerful walls in Xintiandi. The New World, we will admire this place as a holy place. Humanity's ideals are within this wall. Let's create a world without war within this wall. Judging from the sheepskin carrier of this map and the personal name "we", it is obviously not drawn by the person who created this underground facility. It is obviously that Allen's father brought things from the outside world. If this map was not intentionally faked, the information revealed in it would be quite intriguing. First of all, the military strength of a civilization that can create underground facilities of this scale must be at least equivalent to the level of World War II in the real world. If it is a normal offensive and defensive war, it is impossible to be defeated by a giant without wisdom. Secondly, most human deaths are caused by humans themselves, which means that the situation at that time was very chaotic, and the order of human society almost collapsed rapidly in a short period of time. Thirdly, with the technological level of mankind at that time, there may not be more ships to transport survivors, but it is definitely not without the ability to sail across the ocean. Even so, half of the population was lost in the process, which means that there must be something wrong on the ship. Something happened, and it was definitely notMechanical failure. Finally, judging from the tone of the map maker, it seems that this so-called New World was originally uninhabited by humans. However, in a world with advanced technology, an undiscovered land is itself an incredible and strange thing. Then the only possible explanation is that someone concealed the existence of this continent from the beginning, and the purpose was probably to cover up these three walls. *** The parchment map and the translation exist in the "Attack on Titan" manga, on the cover of the first volume of the standalone volume
