Song Zhe kicked Qi Xing Chong, Qi Xing Chong opened his blood basin and wanted to bite Song Zhe, but because he lost the support of his limbs, he could only gnaw on the soil.

"It's pretty good." Song Zhe jumped onto the head of the Qi Xing Species, and there were already many other giants gathered around him, since there was already a Qi Xing Species, the other giants did not have much research value. The attributes possessed by ordinary brainless giants are all possessed by the Odd Species, and the ability of the Strange Species is stronger.

The sword flashed, and there were more than a dozen giant corpses on the ground.

Song Zhe took out a small box from the horse's back, and a row of needles and test tubes were neatly stacked inside.

Theoretically, the giant's bone marrow fluid can be preserved in a sealed device, but it is not clear whether it can be preserved.

Song Zhe cut open the spine of the strange species with a single sword, and the hot steam gushed out. If it were an ordinary person, he would have been burned by the heat a long time ago, and even lost his life because of it. It's just that Song Zhe's strength is too strong, and the steam at this temperature will not cause him any harm.

The needle pierced into the bone marrow, and Song Zhe successfully extracted ten milliliters of giant bone marrow.

However, due to the high temperature, the syringe is softening at a rate visible to the naked eye.

Song Zhe was stunned, and the needle was no longer usable.

"It's a pity." Throwing the needle aside, Song Zhe took out another needle, and at the same time did not forget to cut off the limbs that had just grown out of the strange species.

With experience this time, Song Zhe acted quickly, and immediately injected the bone marrow into a test tube after extraction, and then sealed it.

Looking at the pale red liquid in the bottle, Song Zhe exhaled lightly.

It worked.

Although the liquid was slightly vaporized at first due to the sealing, it was still intact in general.

Song Zhe completely solved the strange species with a knife, carefully put the obtained liquid into the box, and then untied the reins of the horse, turned over on the horse, and continued the journey to collect the giant's spinal fluid.

He walked for a month, and in the past month he had walked around the wall of Mary, and even ran outside the wall, only to find that there was a forest outside, and I don't know how many giants lived in it. And the farther away from the wall of Mary, Song Zhe felt the more abundant the moisture, until he saw the endless sea.

"It turned out to be an island. It's interesting, humans can't really just retreat to this island, right? Giants are indeed very incomprehensible, but according to the speed of human reproduction, it is not necessarily impossible to destroy them. Song Zhe touched his chin and fell into deep thought.

The sun sets and is reflected on the sea, forming a beautiful picture.

"What a beautiful view, you have at least the whole world." Song Zhe sighed with emotion, and then looked for some dead branches on the beach and made a fire.

For hundreds of years, he was the only one who had been so leisurely wandering outside the walls, and he was the only one who had seen the sea.

"A bird in a cage, a turtle in an urn. I really don't know how they have come over in the past 100 years, a hundred years have passed, there has been no substantial progress in science and technology, and the society is still the same as a hundred years. "This world is extremely scary, and it always feels like there is a force in the dark that controls everything.

There are no giants here, most of the giants move around the walls, and the sound of human activity there is easy to attract their attention.

At dawn the next day, Song Zhe mounted his horse, and it was time to go back.

When he came, he had brought a total of 100 test tubes, and now that the 100 test tubes were full, it seemed pointless to stay here any longer.

On this island, Song Zhe has seen too many strange species, and every time he sees a special one, Song Zhe will collect the bone marrow fluid in it.

What impressed Song Zhe the most was that he was a strange kind of writing who could write. The guy didn't seem interested in anything around him, just squatting on the ground and writing and drawing.

When Song Zhe cut his bones open and extracted the bone marrow fluid, he could not be shaken in the slightest.

It takes relatively little time to go back.

No longer having to deliberately look for the giants or deliberately attract their attention, Song Zhe went straight to the Wall of Maria.

The oversized giant gave Song Zhe a little convenience, and he could ride his horse into the wall through the big hole that he kicked out.

Back in the familiar pasture, I really don't know what happened to the people who lived inside the walls during the time they left.

"Captain, there's someone there!"

The Survey Corps still routinely patrolled between the Walls of Mary and Ruth, observing the distribution of the giants. By the way, find out if there are still survivors.

Someone had sharp eyes and found the dusty Song Zhe.

Song Zhe also saw them, and he rode his horse and ran towards them.

"Who are you?" A soldier from the Survey Corps looked at Song Zhe vigilantly.

Although Song Zhe had a three-dimensional mobile device, because it was not very easy to use, he had already thrown it on horseback. It was a secret trip, so he didn't wear the clothes of the boot training corps.

"I'm Song Zhe, the head of the recruit training regiment, and I just came back from a mission outside."

A few people were stunned for a moment, leaving two people to take care of Song Zhe, and the rest of the people gathered together and muttered quietly for a while.

The captain of the team hesitated, pinched the horse's belly, and came to Song Zhe.

"Captain Song Zhe, we can't confirm your identity yet, so please don't walk around at will and follow our team."

Song Zhe spread his hands and said it didn't matter.

He was just doing business, and he didn't mean to target him. And because he was operating in secret, there were very few people who knew that he was out of town, and almost no knew when he would return.

It is estimated that those pot-bellied aristocratic lords already thought that he was dead outside, right?

Song Zhe expressed disdain for them, a group of idiots who only knew how to defend their own interests, really didn't know what was wrong in this world, and let this group of wastes rule for so long.

Going back with the Survey Corps will save you a lot of trouble.

For example, without the Survey Corps, Song Zhe's entry into Ruth's wall is a problem.

He could have climbed over the wall on his own, but what about the horse? After more than a month of getting along, the horse didn't know how much he had suffered with him, and in order to attract the attention of the giant, the horse had made a great contribution.

If he could, Song Zhe didn't want to leave it still outside the wall and let the giants eat it.

The Survey Corps was about to return to Ruth's Wall, and Song Zhe was able to hitch a ride.

As Song Zhe guessed, those aristocratic lords saw that Song Zhe had not heard from him for more than a month, and they really thought that Song Zhe had died outside.

There are all those terrible giants out there, and no one believes that a human can survive the siege of so many giants.

Even if the survey corps were to be dispatched, it would not be possible to hold on for long under the attack of the giants.
