Not knowing the question in Li Mengde's heart, Zhou Yao then asked about the method of suppressing the urge to suck blood.

"It's an alchemical potion, and I have most of the materials in my residence here, but there are two materials that I need your help with." Mondstadt paused and said.

"Which two materials, as long as they are here, I will definitely get them back for you!"

Zhou Yao patted his chest and said with a guarantee. Uncle Lei next to him also has a similar meaning.

As long as Lei Ruxue's blood-sucking impulse can be suppressed, even the most rare material Zhou Yao will find a way.

"One is serum, as long as there is blood, I can refine it."

Seeing that the two of them were so concerned, Li Mengde did not sell Guan Zi and directly mentioned it.

"It's simple, what kind of blood do you want, even if it's dragon blood...... I really can't get this one. Halfway through the words, Zhou Yao suddenly became deflated.

He really didn't have a way to get dragon blood, not to mention the strength of the dragon species in this world, he didn't even know where there were dragons.

"It's so exaggerated, the fresh blood of animals can." Li Mengde was amused by Zhou Yao's words and explained.

"However, if you want to have a good effect, it is better to have human blood." After a moment's hesitation, Leemond said it anyway.

"What's the difference?" Zhou Yao frowned and asked.

Looking at Leemond's hesitant appearance, it was obvious that he was a little worried about human blood.

"Hmm...... After all, this potion is a temporary suppression of the urge to suck blood, the more you use it, the weaker the effect, if you want to use it for a long time, human blood has the best effect, but ......" Li Meng said here and paused.

"With human blood, over time, an addiction that is different from the urge to suck blood will gradually develop."

Zhou Yao didn't understand what kind of addiction Li Mengde was talking about, so he hurriedly asked.

"What kind of addiction?"

"An addiction that is strongly attracted by the owner of blood." Li Mengde spread his hands and said.

"Uh...... In other words, is it the kind of sudden goodwill? Zhou Yao sweated for a moment and asked.

"Well, although there are some differences, you can understand it that way." Leemond nodded.

Zhou Yao was helpless, so he had to look at Uncle Lei to seek a decision.

In his opinion, he wanted to use human blood, so it was not a dirty reason, and he didn't need Lei Ruxue, he just felt that the effect of human blood was more durable.

However, this choice still needs to ask Uncle Lei's opinion, and if he doesn't agree, Zhou Yao can't force it.

"Then human blood, just use yours." Somewhat unexpectedly, Uncle Lei made a choice after a little hesitation.

Hearing him say this, of course Zhou Yao had no opinion.

"Okay, the next second material is gemstones." Seeing that the two had made up their minds, Li Mengde went on to say the second material.

"Jewel...... Well, okay. Zhou Yao was a little surprised, but it was also expected.

Gems are originally a high-grade magic material, and there is also a gem magic that specializes in the use of gems, which is the one that Rin Tosaka is good at. If the material used to make the potion is also understandable.

At present, it is not too difficult to collect gems in Yode City, and you can get some by going to some jewelry stores or the mansions of the rich and noble.

If you really can't do it, you can go to the nobles in the refuge cave to ask for it, for Lei Ruxue, he has no burden as a villain.

"Then I'll go find the gems, and where to gather them when I find them." Zhou Yao asked.

"Go to my temporary quarters, or you decide." Lemon didn't have much to ask for this.

"Then I'll go back to the bungalow when I find the gems, by the way, how many gems do you need?" Zhou Yao almost forgot about this, and hurriedly asked.

"Uh...... With so much, you can make about a month's supply. Lemon didn't know how to describe it, so he gestured with his hands and said.

"Okay......" Zhou Yao nodded, leaving Sakuya alone and bidding farewell to everyone.

Now that there was not a single Dead Apostle in the city, there was no danger for him to act alone.

Anyway, are you still brushing ghouls...... Thinking of his other heroic spirit, Zhou Yao muttered to himself.

He opened the progress of unlocking, and saw that the numbers on it had been beating again and again, and the number had been wiped out by almost 50,000, so he had to make Zhou Yao sigh at his hard work.

The second stay has no attack means of large-scale killing, and can only rely on personal perverted force to kill, of course, the speed will not be very fast.

Seeing that the speed of beating is getting slower and slower now, Zhou Yao guessed that the second stay may be tired of killing, after all, they are all cannon fodder-level combat power that is not worth mentioning, killing them is no different from repeating the same action, and it is normal to get tired.

"Well, this progress is already very gratifying."

Zhou Yao closed the information panel and walked through the streets, looking for a jewelry store or a jewelry store.

After searching for a long time and not finding any of them, Zhou Yao reconsidered whether to be a robber over there in the place of refuge.

In the space of thinking, he had already come to the center of Yode City, and looking at the slightly dilapidated City Lord's Mansion, Zhou Yao decided to go in and have a look.

In any case, they are the biggest nobles in Yode City, and they must have precious stones and other valuables at home.

"I've got the bean sprouts, he's sure to be familiar with this place."

Standing at the door of the City Lord's Mansion, Zhou Yao hesitated to find Doug from the refuge cave.

Suddenly, three familiar figures appeared in his field of vision, and they walked out of the building in the City Lord's Mansion, and it was Doug and Blowing Snow and Deep Snow that he had just risen.

really said that Cao Cao Cao was here...... Zhou Yao couldn't help but think of this proverb.

"Why are you here?"

"Why are you here?"

The two parties asked at almost the same time, and Zhou Yao was the first to explain.

"Because I found something, I need gems very much now, so I came here after looking for them, and I wanted to come in and have a look."

"Gems? What magic research is it used for? ”

Doug is also very clear about the usefulness of gems, and occasionally he also uses his resource quota to exchange some gems from the family to practice his skills.

"Almost, make a potion." Zhou Yao replied.

"Oh, there are a lot of them at home, and now there are no living people, so it's nothing for you to take them." With that, Doug took Zhou Yao into the City Lord's Mansion.

"Why are you back here, uncomfortable living in the vault?" Walking on the road, Zhou Yao asked again.

"As for the current situation in Yoder City, I, as the only remaining member of the city lord's family, must have something to do. So I thought about trying to contact the clan on the other side of the main city. Doug patted his chest and said as a matter of course.

"I didn't expect you to be so responsible." Zhou Yao was a little impressed by Doug.

"Of course." Doug puffed up the tip of his nose and said proudly.

"But aren't all the means of contact scrapped?"

Zhou Yao remembered that Warrier once seemed to say that the contact between Yode City and the outside was cut off.

"It's true, but it doesn't mean that you can't get in touch with the outside."

Doug said with some mystery in his mind.
