"Three, have you ever wondered how the Wall of Mary, the Wall of Rosse, and the Wall of Sheena were built?" Ian's pupils reflected the flame of a burning candle: "Have you calculated the manpower, material resources, and time required to build such a wall?" If it were to be done by humans alone, can you imagine what a huge project it would be? ”

"The question... Wouldn't it be too sensitive? Hanji whispered.

"It's okay, Hanji, it's just the four of us in this tent." Erwin looked at Ian, "Let me answer the question just now." ”

"There is no description in the history books about how the wall was built, there is only one thing recorded on it, about a hundred years ago, human beings entered the wall in order to escape the sudden appearance of giants, and then, the human beings outside the wall were all extinct, and the human beings in the world, only we who lived inside the wall were left, so we don't know how the wall was built."

"Do you know how the walls are built, kid?" Levi leaned back and lay down in his chair.

"Yes, I know." Ian nodded: "Inside those walls, in fact, all of them are super-large giants about fifty meters tall. ”

"What did you say?!" Hanji's glasses almost fell off: "The giant is inside the wall!" ”

"That's right." Ian went on to explain, "Those walls, in fact, were built by hundreds of giants acting as walls, and those giants had a hardening ability, and they were arranged together, and then they hardened the surface of the body, and they became walls. ”

"They can't get sunlight inside the wall all year round, so they will stay honestly, that wall, in fact, was built by giants, the three of them should have more or less noticed, the government's protection of the wall, if there is wear and tear, someone will immediately repair it, just to prevent the giants inside from seeing the sun."

"Assuming what you say is true, how are these giants arranged? Will they obediently line up together? Erwin asked.

"This brings us to the secrets of the giants and the royal family of Lacey." Ian said, "Before explaining this part, I would like to ask Captain Hanji, how much do you know about the body structure and living habits of giants? ”

"Well... To put it simply, giants are a completely unreasonable race, although they look big, but in fact their weight is not up to the normal standard, and no matter what kind of injury, as long as the back of the neck is not cut off, they can recover quickly, they have no digestive organs and reproductive organs, they are only aggressive to humans, and after killing, they will quickly turn into steam, they are very active during the day, and become sluggish at night, it is just... The race of another world is the same..."

"Captain Hanji is basically right, but the giants are not from another world, they are humans, they are humans, and they are made of humans."

"What do you mean?" Hanji approached Ian: "Giants are humans, how did you come to this conclusion?" What is the principle? ”

"Sorry, I don't know how it works." Ian was a little farther away: "But I know a fact, in the past generations of the Lacey family, there is a person who can become a giant, and that person is the real king of the wall." ”

"Moreover, after the king of the wall becomes a giant, he can retain his senses, and the king of the wall becomes a giant, an existence that stands at the apex of all giants, and has many incredible abilities, you can understand that one as the king of giants, he can manipulate all giants, and even tamper with the memories of human beings, these three walls were established by the king of the wall a hundred years ago."

"Sounds like... It's like a legend..."Hanji sat back, "Although the existence of the giant itself is already very much like a legend..."

"Leave aside the verification process for the time being." Erwin interjected: "According to what you said, there should also be a king of walls in this generation of the Lacey family, if he can manipulate all the giants, then, why was the wall of Maria breached?" ”

"Because something has changed." Ian replied, "When the Wall of Mary was breached, it was almost the same time that the King of the Wall was premeditatedly killed, and even his power was taken away, so there was no way to stop the invasion of the giants. ”

"Oversized giants and armored giants," Elwin said to himself, "I thought their appearance was strange before, and if it was a premeditated invasion, then it could be explained." ”

"Those sightings..."Hanji licked his dry lips, "I heard that the oversized giants and armored giants appeared suddenly and disappeared suddenly, if... They are human beings, and they can explain this phenomenon. ”

"That's probably it, besides the King of the Wall, there should be other people in the world who can turn into giants." Ian agreed.

"How the hell do you know so many secrets, you little kid?" Hanji felt a little dry in the mouth.

"Because on the farm I live on, there is an illegitimate daughter of the Lacey family." Ian replied, "I was bought to serve that child, the king of the walls of each generation, and after inheriting the power, the lifespan becomes very short, so the heir is well protected, I was raised as the heir protector of that child, and I was taught many secrets by the housekeeper since I was a child." ”

"In order to keep it a secret... Have all the people on that farm been killed?" Elwin said quietly.

"That's it." Ian said with trepidation: "Before the gendarmerie started, I noticed that something was wrong in advance, and I tried my best to escape to the refugee area, and changed my appearance to become a resident of the pioneer land. ”

"You finally escaped, why did you expose yourself?" Erwin's fingers tapped on the table: "Aren't you afraid of death?" ”

"I have a dream." Ian looked Elwyn in the eye.

"What dreams?" Erwin asked.

"I hope that all the children in this land will have enough to eat, all can receive basic medical care and education, and I hope that everyone will no longer be afraid of giants and can live in peace."

"What a big goblin." Levi crossed Jiro's legs.

"What I said is true or false, it's easy to verify, go to the territory of Lacey and investigate the walls." Ian said calmly, "The reason why I'm here is to gain the trust of the three of them, and I know other processes besides the waterwheel, such as more advanced iron smelting methods than now, and better steel formulations. ”

"The Giant and the Armored Giant are enemies, they have already caused tens of thousands of casualties, and I can't deal with them alone, so I want to find friends, find helpers, and I think I should show my sincerity."

"You... Is it really only 11 years old? Hanji gasped, "Levi, do you think an 11-year-old can say such a thing?" ”

"This little ghost is the kind of guy he is commonly known for, an alien from ordinary people." Levi stood up, "Elwin, don't treat him like a child. ”

"I know." Erwin nodded: "Ian, you can go back, as you said, I won't be able to accept what you said for a while, there are too many things involved, but I can assure you that we will not disclose tonight's conversation to others, and I will find a way to contact you later, I hope we can meet again one day." ”

"Hopefully you'd better come early that day." Ian nodded: "The enemy is still lurking somewhere, and there may not be a lot of time left for humans." ”

"I'll get in touch with you as soon as possible, it's too hasty tonight, at that time, let's talk in detail."

"Okay, goodbye then, Captain."

"Goodbye."

Ian was sent out of the tent, and the untied Hannes looked worried.

Ian and Hannes converged, and before they could say a word, the Survey Corps began to pack up.

The soldiers quickly put away their tents, extinguished the flames, and warned the soldiers in the frontier not to reveal their whereabouts.

From the time they arrived at the site to the time they left, the Survey Corps stayed for a short time, and most of the inhabitants were asleep, not knowing where they were coming and going.

Ian looked at the wings of freedom in the distance, and his heart was slightly apprehensive.

The plot is completely messed up, and he can't tell the prophet anymore.

What will be his fate?

Where will this island go?

The answer to everything is unknown.

He can only strengthen his beliefs and go on step by step.

In order to survive, he must go one step at a time.
