Because of this accident, Fang Zheng had to go back to the previous city again... and then came back again.

Well, there are still three people.

The reason was very simple. After Fang Zheng sent the girl back, he was told that the child was originally an orphan. Her parents were killed by human traffickers a few years ago. Later, she was adopted by a doctor's family. However, this family lost contact in the previous giant attack. The mother was killed and the father was missing.

Logically, there was a boy who was inseparable from her, but... when the giant attacked, there was chaos and no one knew where the boy had gone.

So Fang Zheng had no choice but to take the girl away again.

After all, she has lost her memory now, and the other side also looked like "Since you are so powerful, why don't you take this child with you and let her go to heaven with you..." It was obvious that he didn't intend to raise such a girl, so Fang Zheng had to take her away. After all... Speaking of which, the girl lost her memory because of him... No wonder!

It's obviously his own fault!

Forget it, it’s not surprising that children are curious. We can only blame the soldiers for not paying close attention.

Yes, it was all the soldiers' fault.

"Are we really going to take her with us? Lord Kasugano?"

"For now, there is really no better way."

Facing Katima's question, Fang Zheng shrugged helplessly.

"Of course, we can't take her to confront the Light Chasers, so we'll have to see how the situation develops. This continent is so large, there should be other cities. Anyway... for now, let's teach her some survival and fighting skills. That way, even if she leaves us, she won't die."

"That's... okay."

Hearing Fang Zheng's words, Katima hesitated for a moment, then nodded. After all, she was worried about leaving the girl alone. And as Fang Zheng said, the girl had lost her memory and knew basically nothing. What would happen if she was left in that city under such circumstances? If she could learn some skills to protect herself, then even if she encountered any problems in the future, she would be able to solve them... At least she would be much better than she is now.

"very good."

Hearing Katima's answer, Fang Zheng laughed and patted her shoulder.

"Then she's in your hands."

"Hmm...eh?"

"What else? You are all girls, so it's more convenient, right? And you just happen to have a companion."

Seeing Katima's somewhat surprised expression, Fang Zheng chuckled and then turned away. He knew that Katima had been traveling with him until now, and sometimes she would feel lonely. After all, they were a man and a woman, and some things were hard to say. In fact, when Katima first saw the girl, she liked her very much and took good care of her. On the one hand, the girl was indeed pitiful, and Katima was kind-hearted. On the other hand, Katima wanted to have someone to accompany her - well, don't think Fang Zheng didn't see it. When they were about to send the girl back at the beginning, Katima was a little disappointed. Later, when she saw Fang Zheng bringing the girl back, Katima's mood recovered.

This is like a daughter who goes out with her father and sees a doll she likes in the mall. She wants it but is too embarrassed to say so, so she can only look at her father eagerly. If he ignores her and walks away, she will be very disappointed, but she will be very happy if he comes back to buy the doll...

So Fang Zheng handed the little girl over to Katima to take care of, just as if she were a new sister.

By the way, the girl's name was Mikasa Ackerman, which Fang Zheng learned from the guards in the city, otherwise she wouldn't even be able to remember her own name.

In the next two days, Katima was basically responsible for taking care of Mikasa. Although Mikasa had lost her memory, she was still a smart child and the two got along well. As for Fang Zheng, he continued to conduct various experiments on these giants to determine their characteristics.

Soon, through dissecting these giants, Fang Zheng also gained a certain understanding of them.

First of all, it is certain that these giants were once human beings. Later, they were infected by some creatures and turned into giants. The creatures fused into their spines and eventually controlled them, causing the bodies of these humans to swell like balloons and turn into giants.

This is also why those giants evaporate and disappear after they die, because their power actually comes from the biomass that parasitizes in their spine. When the spine is destroyed and the biomass is damaged, they can no longer maintain their huge bodies, and naturally they will die.

But...it is difficult to find the origin of this biomass.

Generally, in movies or games, you will be given a mental network similar to a honeycomb, so that the protagonist can kill the boss directly. After killing the boss, the entire network will collapse, and then the monsters or robots controlled by the network will also be directly destroyed. Then the protagonist saves the world, which is cause for celebration.

But unfortunately, these are just settings for the convenience of manufacturing.

There is no such good thing in reality.

It's like an infectious disease. Even if you find the source of infection and kill it, it has already spread. There is no other way except to fight to the death. The same is true for this biomass. When they merge with humans, they will become independent individuals, and these biomass themselves do not have any special thinking... Well, to put it bluntly, they are just like single-celled organisms, with only instinctive actions and some physical memories of the parasites.

So, here comes the question.

Where do all these giants come from?

Fang Zheng asked the people in that city, but they said that few people disappeared in this city. No one went out on weekdays. Only the "Survey Corps" would go out to investigate the giants. Of course, they suffered heavy losses every time. However, according to these people, the number of people in the Survey Corps was not large. There were only a few dozen people every time they went out, and most of them were eaten by the giants.

Only a very small number are missing.

Moreover, Fang Zheng also confirmed that these giants were not contagious, which meant that people who were eaten by them were really eaten and could not turn into giants.

So, there is a problem.

This kind of thing is not contagious, and Fang Zheng has asked the lord of that town, and he is very sure that their city is the only place on this continent where humans live, and there is no other city. In fact, Fang Zheng did find some ruins during his flight over the past few days, but he did not find another city with a fifty-meter-high wall like that... In other words, he did not even see a living person.

Logically speaking, there should be fewer and fewer giants like these. According to the city lord, they have not been attacked by giants for nearly a hundred years. According to normal biological theory, these giants should have been extinct long ago.

However, in fact they did not become extinct, and there even appeared a giant who was taller than the 50-meter city wall. He could kick down the city wall with one foot and even disappear?

Where did these giants come from?

It can't possibly grow out of the ground.

Fang Zheng has determined that the biomass that can turn humans into giants is a parasitic existence, that is, unless there are humans or similar vertebrate creatures, they cannot merge with them and turn them into giants.

Therefore, it is certain that there is definitely a place that is continuously "producing" humans, allowing those biomass to parasitize and eventually turn them into giants.

So, where will it be?

Fang Zheng spent the next few days looking for clues, but unfortunately he didn't get any results. On the contrary, Katima and Mikasa got along well and they were like sisters.

Of course, Fang Zheng also talked to Mikasa about why he was on this ship, but she said...she couldn't remember why she did that at all.

Forget it, if I can’t remember, then forget it.

However, three days later, Fang Zheng finally found an exciting clue.

On the other side of the horizon, he discovered an exciting city...the ruins.

That's right, this city has been destroyed, with only ruins left. Judging from its appearance, it must have been destroyed hundreds of years ago.

However, for Fang Zheng, what is important is not the ruins, but the information and records in the ruins.

For example, these murals.

"It seems that we have found some clues."

Standing in front of the tall city wall, looking at the murals on the wall, Fang Zheng couldn't help but sigh. Beside him, Katima and Mikasa also looked at the murals in front of them curiously.

The city wall was tens of meters high. Although not as high as the previous city, it was not bad. Although it had experienced a hundred years of wind and rain, it still stood firm. However, only this city wall remained. The once magnificent castle and the once prosperous city had completely turned into a pile of ruins in the dust of history.

However, for Fang Zheng, the city’s century-long prosperity is not important. Instead, what is important is the content on the murals.

The first mural depicts a girl kneeling on the ground with her hands raised high, as if praising the sun. Above her head is the shining sun.

The next painting showed something like a snake falling from the sun and then attaching itself to the girl's body.

The third painting shows the girl turning into a giant with great strength and sturdy body, helping others build houses and cities.

The fourth painting tells the story of a girl who marries the king, becomes the queen, and then rules the kingdom under the shining sun.

There are some murals at the back, which are nothing more than praising the king, praising the greatness of the sun god, and some things that happened... but these are not important.

For Fang Zheng, the most important part has been found.

"So, those giants are a blessing from the sun god?"

After listening to Fang Zheng's explanation, Katima was also stunned.

"But why did they become like that? According to the mural, isn't it good for the girl to become a giant? She helped everyone build houses and cities, and she also married the king. It can be regarded as a beautiful and happy ending."

Indeed, Katima also felt it was a bit strange. After all, the giants she and Fang Zheng had seen had almost no self-awareness. They looked stupid and dumb all day long, and only attacked like crazy when they saw people. If this was the case, then the girl should also become crazy and attack other people.

But the murals say she helped others build the city and married the king...

"It may not have been like this originally, but became like this for some reason."

As he spoke, Fang Zheng pointed at the ruined city around him.

"After all, murals are meant to extol merits. But as you can see, if everything on the murals was real, this wouldn't have happened."

“…”

Hearing Fang Zheng's words, Katima and Mikasa turned their heads and looked around. The entire city was in ruins. Not only that, from the huge gaps and ruins, it could be seen that the city was not abandoned naturally, but had gone through a brutal and fierce battle - they could even see piles of bones in some of the ruins that were not buried by the yellow sand.

"Okay, let's go look around, maybe we can find something interesting."

After Fang Zheng spoke, Katima and Mikasa also scattered out of curiosity, wandering around in the ruined palace. Especially for Mikasa, everything here was so new. She didn't know if she had encountered similar things before she lost her memory, but at least after losing her memory, everything in front of her looked very interesting to Mikasa.

"Alas?"

When Mikasa walked into a room deep in the palace, her eyes were suddenly attracted by something in the corner that reflected the sunlight. The girl walked over curiously and saw a strange silver ornament in the gap. She reached out curiously and picked it up from the gap.

"What's this?"

Looking at the triangular silver piece in her hand, Mikasa curiously stretched out her hand and poked it a few times, but there was no response. However, the girl still liked this thing very much, after all, it looked like a pretty hair accessory. So Mikasa also picked up the silver "hair accessory" and stuck it on the hair beside her ear.

“——!!”

However, what Mikasa didn't expect was that the moment she put the "hair accessory" on her hair, it seemed to generate a kind of suction and stick directly to her head. Then, a beam of light shot out from the silver triangular "hair accessory", and a picture suddenly formed in front of Mikasa!
