"I want to guarantee that there is only!"

Lu Yu's voice fluttered in the middle-aged man's ears, making the middle-aged man's face extremely pale.

Lu Yu is too calm, but it is a bit scary!

"One, how could it be the only one!" the middle-aged man said tremblingly: "Sir, I gave you the recipe. Do you want my life?"

He knew that he could extract the formula.

If he wants to be the only one, he can never speak.

But only dead people will not speak.

If he is caught, may he not disclose it for his life?

When the formula is revealed, who dares to say that there will be no other refining method in this world?

It is possible to ensure the uniqueness of the formula unless he dies!

Lu Yu shook his head and said, "I have no interest in your life! I just hope you can guarantee the uniqueness of this recipe. Except for me, there will be no other person in this world to get the recipe."

"Sir, how is that possible?" the middle-aged man raised his hand and kept trembling, "Unless I die, you and I will always know this recipe. I can only guarantee that my younger generations don't know, but I can't erase my memories."

Lu Yu's eyes were filled with cold chills and said, "Then, the only way is to die!"

The middle-aged man's heart trembled.

He suddenly realized that what he was holding was not a treasure, but a death talisman!

When he got it, he just wanted to make money, but he forgot that there were some things no one was willing to share with others.

Especially the formula of evolution fluid, no matter who gets it, you definitely don’t want a second person to have it.

When Lu Yu said the word "death", the middle-aged man was desperate and his expression became extremely pale.

"Die, do I have to die?" the middle-aged man smiled and said, "I finally understand what 'human death is'. For the sake of wealth, I really forgot the danger. What I have is the god of death, the god of death that takes my own life. If I can't keep this secret, I can only die!"

The middle-aged man was desperate. After hearing Lu Yu's words, he knew that his death was coming.

That paper is not a star treasure and will not disappear with death.

So if Lu Yu wants to kill him, he can still take away the recipe.

Lu Yu stood there without moving, just staring at the middle-aged man quietly, waiting for the middle-aged man's answer.

"If I die, can you keep my nephews safe?"

"As long as they don't do evil, I will kill anyone who dares to touch me!" Lu Yu replied, his tone was very domineering and boundless murderous aura.

"Okay, very good." The middle-aged man took the recipe back into his hands and handed it to Lu Yu with both hands, saying respectfully: "If it were someone else, I would definitely compete with you. But I believe Mr. Lu's reputation, you can do it. For the reward for formula trading, please give me a few younger generations."

The middle-aged man had long guessed Lu Yu's identity, but Lu Yu didn't want to say more, so he didn't dare to say it.

Now, it’s the same whether you say it or not.

Lu Yu took the recipe, took a look, put it in his storage space and said, "Don't worry about this. Even if you die, I will still abide by the agreement and give the money you should give."

The middle-aged man smiled bitterly and pulled out the star soldiers, turning them on his chest.

die--

Maybe it will end quickly if you have a sword.

But how many people can really stab this sword.

How many people have such courage to commit suicide?

The middle-aged man held the sword and stared blankly at the sharp eyes, and could not stab the sword.

Lu Yu didn't say anything, and kept standing still and moving.

The middle-aged man looked at Lu Yu and originally hoped that Lu Yu would suddenly stop him, but now it seems that he is still too naive.

The middle-aged man gritted his teeth and threw the star soldiers on the ground and said solemnly: "Mr. Lu, I will never leave Fanggang! If you want to ensure uniqueness, then I will help you make evolution liquid. Is this okay? My only requirement is that you must protect the lives and safety of my sons and nephews. I hope they can qualify to enter the list of the first field of Fanggang. Once there is any danger, they have a place to be protected."

In this world, the safest place is Fanggang.

The most reliable place is the first area, where defenses are indestructible once they are opened.

This is something hundreds of thousands of soldiers have spent several days experimenting with, and it is an indestructible city.

If the end of the world really comes again, the safest thing is to be in Fanggang.

"Okay." Lu Yu raised his lips slightly and said, "I give you the qualification to enter the core field, but someone will keep monitoring you. Your range of activities is limited to the first field. And if you want to go out, you must be protected by my warriors. I don't want you to have any surprises. As for those young people, you can rest assured. I still say the same thing - it's not illegal, I will kill whoever dares to touch them!"

Lu Yu doesn't want to kill anyone.

But in such a world, you must be cruel enough.

If a middle-aged man doesn’t make his last choice, he must die!

Now that Lu Yu had agreed, the middle-aged man's face was covered with blood.

Lu Yu has been waiting for his answer all the time.

He would not force himself to die, but to ensure the uniqueness of the formula, he had to make some cruel decisions.

"But--" the middle-aged man frowned and said, "Mr. Lu, I'm afraid that people from all forces from all sides have surrounded this place outside the stone house. How do you want to leave?"

Lu Yu was very calm and said coldly: "I don't need other people's consent to leave here. If I don't agree, come and fight!"

When middle-aged people listened to Lu Yu's words, some of them were left admiration.

Lu Yu was too calm, as calm as a machine. Lu Yu was more like a killing machine.

When a middle-aged man stood in front of Lu Yu, he always felt like he was facing the god of death.

Lu Yu looked at the middle-aged man and said, "Remember your words, if you dare to repent, I think there are not many people in this world who can protect you. Even if you are protected by the military of that country, I will kill you."

"Mr. Lu, I understand." The middle-aged man nodded and replied.

Lu Yu stopped talking and pushed open the door of the stone house first.

The sky was dark, and the bright stars shone on everyone's hair and fell on their shoulders.

The surroundings are very quiet.

Everyone was waiting for the people who came out of the stone house.

No matter how big the stone house is, it is still large and limited. No matter how dense the crowd is, you can see Lu Yu only the innermost part and some humans standing slightly higher.

Lu Yu and the middle-aged man walked out together and immediately heard someone shouting: "Friend, how much does your evolution liquid formula cost?"

"No need to ask for the price, we'll want it."

A big man's eyes were blood red, and his teeth were jagged in the shadow of the forest, and he smiled: "You pay for the price, and our bloody eyes accepted it."

All kinds of sounds were heard around.

Many large organizations and some military personnel have quoted.

They didn't see the faces of the two people walking out of the stone house at all, just for the initial impression.

But as they gradually saw the faces of the two people who walked out, many of them changed their expressions.

Not everyone knows Lu Yu, just a part of it is enough.

Chen Long pointed to Lu Yu and said, "Brother, it was him who bought our things!"

Zuo Haiyan said in a grim voice: "Okay, very good. I'm so lucky, I actually saw it here."

A British military representative had a numb scalp and said, "What, how could this be? It was him!"

Some organization experts also recognized Lu Yu and smiled bitterly: "It's bad. If it's not good to fall into someone's hands, it's actually in his hands."

When a blonde beauty saw Lu Yu, she immediately shook her head and smiled at a black man beside her and said, "Do you still rob me?"

The black man was stunned for a long time and could not kill him.

"Grab, how do you grab this?"

The black man is helpless. He is still one step late.

Some people can rob, but some people you can't move.

Just like now, if you let them move, they dare not.

The middle-aged man around Lu Yu walked forward at this time and clasped his fists and said, "I'm really sorry for everyone. I've sold the recipe. Youdao means that if you don't sell the goods, don't think I'll sell them again."

The middle-aged man said this, and the young people in front of the stone house immediately cheered.

They succeeded.

With 20 billion star spirit stones and other things, they can at least build a force that is not weaker than the Qin family.

One person looked at Lu Yu and said coldly: "My friend, don't you think you can afford to get the formula of evolution liquid alone?"

Lu Yu glanced around and said calmly: "I can naturally afford the money, so you don't have to worry about this. I just want to ask here, don't you have any objections to me having this recipe?"

"Of course I have an objection." A black wolf wandered around and walked out arrogantly and said, "I heard that the refining of evolution liquid requires a large number of stars and the soul of the blue star. Do you have one?"

Lu Yu said coldly: "This has nothing to do with you. I bought the recipe. As for how to use it, you don't have to worry about it."

"What?" The black wolf roared, his eyes wide open, and his black hair exploded, and his surging force was surging like a wave.
