"No... This key... It's not the one who opened this door," Alan said stunned.

"Let me come." Levi stepped forward, handed the oil lamp to Allen, and stretched out his right leg to kick in a voluptuous pose.

He kicked through the wooden door, and a smell of closed dust came in.

The crowd pinched their noses and broke into the basement.

"Dried herbs, prescriptions, patient records..."Hanji picked up the medicine in the cabinet and the notes on the table, "It looks like it's a doctor's studio." ”

"It should have been deliberately decorated like this." Erwin said, "Look again, there must be somewhere to use Allen's key." ”

Ian stood in the doorway, watching the busy crowd.

Ymir and Hannis stood behind him, holding oil lamps.

Soon, they found something wrong on the workbench, there was a lock hole in the drawer, Alan took out the key and inserted it into the lock hole, there was a sound of metal snapping inside, he twisted the key and opened the lock of the drawer.

Inside the drawer was a mezzanine, and from it, Hanji took out three notebooks.

"The flavor is peppermint oil and charcoal, and it's also treated to repel insects and moisture." Hanji twitched his nose, "Looks like that's what we're looking for." ”

The oil lamp was placed on the table, and everyone stood around the table in silence.

Erwin took a deep breath and flipped to the first page of his notes.

What catches his eye is a black-and-white photograph that Ian recognizes at a glance.

The photograph shows a man, a woman and a child, both men and women dressed in decent clothes, and the woman sitting on a back chair with her child in her arms.

"It's... Draw? Erwin frowned, if it was a painting, it would be too realistic.

"No... No... This is a material that has never been seen before. Hanji picked up the photo and observed it through the firelight: "I think I used some means to record the moment that my eyes can see." ”

"There's a word on the back!"

Hanji flipped the photo over and read it out.

"It's not... Painting, which is ... The light reflected from the target... Engraved on special paper... It's called [Picture], and I'm from outside the walls, where humans live gracefully. ”

"What do you mean?" Levi frowned: "Shouldn't the walls be full of giants?" ”

"Let's read the contents of the notes first." Erwin didn't show any surprise.

He had expected that he would even feel a sense of excitement when he heard the phrase, "I come from outside the walls, where human beings live gracefully."

Sure enough, he and his father's guess was correct.

There is simply no evidence that humanity outside the walls is extinct.

The history books of the royal family are simply fabricated lies!

"I'll read it."

Erwin held the first notebook in his hand and read it aloud.

"Humanity is not perishing, and I hope that the person who first got this book is my comrade."

"My name is Grisha Yeyer, and I'm from Marais, on the other side of the sea, where science and technology are many years more advanced than the inside of the walls."

...

Everyone in the basement listened quietly as Erwin read the three notebooks left behind by Grisha Yeyer.

Grisha Yeager has recorded almost everything she has done since she was born.

He wrote in his notes that he was an Eldian born in Marais, and in Marais, all Eldians were discriminated against.

The people of the world consider the Eldians to be a demonic people.

"My father told me that the history of the Eldian people begins in 1820, when our ancestor Ymir Frieze made a pact with the Earth Demon and obtained the power of the giants, and after Ymir's death, his soul split into nine giants and established the Eldian Empire, which destroyed the ancient great power Marais and became the ruler of the land.

After that, the Dark Ages, when the people of Ymir regarded other races as inferior and began to ostracize them.

The purge of the people of Ymir lasted for about 1,700 years, as they seized land and property, and forced other peoples to give birth to children.

However, Marais, the former great power, won seven of the nine giants and won the battle of the giants eighty years ago, when King Eldia fled to the island of Palladium, built three walls, led the people, and fled into the walls.

Our ancestors were abandoned by them in the land of Marais, but the magnanimous Marais, not only did not kill us, but also gave us land, and we want to atone for the sins of the Eldians, so we can never step out of the control zone, and we must always obey the orders of the Marais.

That's how I was raised, but... My sister, Faye Yeager, that day, I took my sister with me to see the airship, and my eight-year-old sister was mauled to death by Marlay's police officer, a dog, because of this discrimination, and her body was dumped in the river. ”

...

What Grisha Yeager expounded was nothing short of earth-shattering for Erwin and others.

How the walls were built, why were there so many giants outside the walls, and by what means were the power of giants passed on...

Almost all questions can be answered in these three notebooks.

When Alan heard half of it, he was even more stunned and sat down on the ground.

According to the book, the way to inherit the power of giants is to become unconscious and unsullied giants, and then eat the human form of intelligent giants.

His father, Grisha Yeyer, inherited Attack on Titan, that is, his giant power came from his father.

He turned into a giant and ate his father, and those mutilated pictures suddenly appeared at this moment, and he remembered that after the wall was destroyed, it was his father who gave him an injection!

His father found him while he and Mikasa Armin were on the run and passed on the power of the giants to him.

The power of giants is not his "talent".

"While hopefully there will be new discoveries... But this intelligence... It's too exciting..."Hanji swallowed: "Marai, the Nine Giants, the King of the Walls who negate the battle... Is the world outside the walls so exciting? ”

"Ian, you don't look surprised?" Erwin closed the last notebook and shifted his gaze to Ian.

"Well... After all, there are some things I've already heard. Ian spread his hands.

"Heard? What do you mean? Hanji turned his head: "Did you already know these things?" Where did you find out? ”

"Actually, one of our people came from Marais." Ian stepped out of the way: "Ymir, you can explain." ”

"Is there a link?" Ymir hugged his chest.

"I just decided." Ian smiled: "You can explain first, I want to take everyone to the beach tonight, and I may have to trouble you later." ”

"Do you want me to be a means of transportation..."Yumir sighed, "Well, who made you my commander?" ”

Erwin and the others didn't understand Ymir and Ian's conversation, but they would see the scenery they would never forget in a few hours.
