Zhang Yue still has some understanding of the giant potion, although it basically does not appear in the animation, but because of the relationship between the few white absolute ones he sent, he still learned some information about the giant potional from Ma Laiguo, and aroused Zhang Yue's interest, this kind of product that is obviously the product of the people of this world after studying the power of the giant will also have a lot of reference value for him.

However, because the Marai people attach great importance to the giant potion and keep it quite secretly, although Zhang Yue's power in the Malai country has tried several times, he has not been able to get the giant potion.

Unexpectedly, he encountered a giant potion researched by the people inside the wall here, which really made Zhang Yue feel that it was an unexpected joy.

Originally, Zhang Yue really didn't think that there would be this thing in the world inside the wall, after all, the Ancestor Giant could have directly turned the Elidian into an innocent giant, so the world inside the wall should not be able to use the giant potion, but then, Zhang Yue reacted, why did Rhodes study the giant potion.

"I'm afraid it's because the Ancestral Giant was taken away, I'm really powerful and a little reluctant to use my brain, I should have thought that after the Ancestral Giant was taken away, if they wanted to take it back, it was too normal to study the giant potion, otherwise even if they caught the Ancestral Giant, they wouldn't be able to turn the chosen Ancestor Giant successor into an Innocent Giant and snatch back the power of the Ancestral Giant."

Zhang Yue had a thought in his heart, and the subsequent conversation between the two in the study also confirmed this guess.

Kenny in the study was a little surprised when he heard Rod's words: "Is there something wrong with the Giant Elixir?" Didn't you say that the research on it was confident, and there would never be a problem? Speaking of which, there were already some questions in his words, and it seemed that this guy named Kenny had no respect for Rhodes, the supreme ruler within the walls.

"Hehe, don't worry, man, we don't have any problems, it's just that the research has made significant progress." Rod didn't care about Kenny's tone, and explained with a smile.

"Really? But didn't you just tell me last week that it would be difficult to make a breakthrough in the research of giant potions within half a year? Besides, it's too late to talk to me about this kind of thing during the day. A hint of surprise flashed across Kenny's face, but he was puzzled by Rhodes being in such a hurry to find him in the middle of the night.

Rod smiled a little, and sighed: "Where can this thing be completely predicted, my previous predictions are actually conservative estimates, but sometimes luck can't stop it." ”

After that, he walked to the desk in front of him, picked up a few pieces of paper and handed them to Kenny, and said, "As for why I found you in the middle of the night, it is indeed because I am a little anxious about this matter, I think it is safest for you to sit there, you take a look at the things on it first." ”

Kenny took the paper and looked at it seriously, a hint of surprise flashed on his face, and then nodded: "I see, it should indeed be safe, so let's go to the experimental site now and take a look, if there is no giant potion, even if we catch the guy who stole the power of the ancestral giant, there is no way to snatch it back." ”

With that, the two of them took a few materials from the desk, and immediately left the study through the secret passage, looking like they should have gone to their experimental site for studying giant potions.

And not long after the two left, Zhang Yue, who had already confirmed that the two of them were leaving, entered the study, looked at the bookshelf blocking the entrance of the secret passage, with a smile on his face, and muttered: "Originally, I thought that you were just the inheritor of the royal bloodline with some research value, it seems that there are other uses, at least your research may be of great value to me." ”

After that, Zhang Yue opened the mechanism of the secret passage almost without thinking about it, and then stepped in.

He had just relied on his powerful hearing outside the study to basically judge the general structure of the secret passage mechanism, and at this time, he knew how to control the secret passage exit after just a few glances.

Speaking of which, Zhang Yue's value to Rhodes was just a research item, and although the other party was the actual controller of the world inside the wall, to be honest, because it was hidden behind the scenes and not known to the vast majority of people, even if it disappeared, the real impact on the world inside the wall would not be great, and even after his disappearance, it would be more conducive to Zhang Yue's control of the world inside the wall.

Therefore, Zhang Yuecai planned to secretly and directly arrest him as an experimental subject, and he didn't care about the impact of his disappearance.

However, at this time, Zhang Yue found that this Rhodes had other values, and he was able to study some things that Zhang Yue was interested in, of course, he was definitely not contributing to the specific research, but as the owner of the royal bloodline, Zhang Yue believed that he must still have an extremely important role in these studies.

Therefore, Zhang Yue planned to let Rhodes study some of the things he was interested in before letting him disappear, and make every possible preparation, and directly use that opportunity to control the entire world inside the wall in the fastest time.

"But although I won't arrest him for the time being, I still have to draw some blood for a while, and having three different samples of royal bloodline is better than just two." Zhang Yue was not close to the two Rhodes who were also walking in the secret passage at this time, and there were many forks in the secret passage, but Zhang Yue followed them without mistake, and they didn't notice it at all.

The secret passage was very long, and Zhang Yue walked for more than a quarter of an hour to reach his destination, and then hid aside and looked at Rod and Kenny who were talking from afar.

And when he just saw the two of them, Zhang Yue's eyes were instantly attracted by Kenny, although he had long known about the existence of the captain of the Central Military Police Corps, nicknamed the Throat Cutter, but this was the first time he had seen each other with his own eyes, although this person looked no different from other Adilians, but Zhang Yue could be sure at first glance that this person was the same as Mikasa and Levi, all of whom belonged to the Ackerman clan.

"Another Ackerman? Hehe, I didn't expect another good research material, today's second unexpected surprise. ”

Through the study of the blood samples of Mikasa and Levi, Zhang Yue had already determined that the Ackerman clan had some kind of connection with the giants, and even made some research progress on the power of the giants in the study of their clan.

"It seems that after drawing Rod's blood, I have to draw out this Kenny's blood, this guy has good strength, and he needs to be cautious when he does it."

Zhang Yue looked at the two of them and thought like this, in the final analysis, the biggest value of these two guys to Zhang Yue is to study materials.
