Tang Yuan was in a good mood, staring at the person in his arms, his eyes full of deep affection: "Look Qingqing, we are destined to be destined."

In his opinion, he and Qingqing were a perfect match.

The corner of Luo Qing's mouth twitched, "That is indeed quite fateful, it has been related before the end of the world, not to mention wait, Luo Qing suddenly thought of something: "What happened to Nan Chen before? You can't even solve it?"

He still has great faith in this guy. It can be said that there is nothing he can't do. This also makes it strange that wages cannot be paid before the end of the world.

You can't just know the end of the world in advance, so you don't care about other things, right?

It seems that this is not impossible.

Tang Yuan didn't expect Qingqing to ask this, but he didn't hide it: "Before the end of the world, I suddenly fell into a coma. I didn't wake up until the end of the world came. When I woke up, I was a level five superpower." When he said this, he couldn't help but sigh.

Tone: "I haven't advanced yet, but I can use powers that feel like level six or seven."

Luo Qing: ""

In fact, there is no need to say the last sentence, it is very hateful.

Tang Yu immediately stopped, staring at his brother jealously, grinding his teeth: "Why, we are also brothers, I have only reached level three now, and you are only level six or seven, it's not fair!"

Leyak glanced at him sideways and said in a faint tone: "Then I still think that you brothers are bullying others unfairly. What can I say for someone who has worked so hard to cultivate? You are so high just after sleeping, so you have the nerve to complain.

?”

"That's right, I'm so angry. Are you lucky because your surname is Tang?" Liang Mimi was also depressed. She had been following her boss since the end of the world, and she never saw him practice, but there was never a time when he was weak.

Comparing people to each other is really irritating.

Luo Qing replied silently after hearing this, it's not the person named Tang who is lucky, it's the protagonist who is lucky.

Tang Yu didn't react. Hearing this, he felt sleepy and raised his chin proudly: "That's right, our Tang family's genes are so good. Look at my sister-in-law, she is not an ordinary person. Our Tang family

The vision is also first-rate.”

Luo Qing: ""

Brother, if you are beaten, I will never help you. You are really owed.

Liang Mimi immediately reached out her hand and pinched his ears.

"Ouch." Tang Yu suddenly wailed and quickly covered his ears, "Sister, sister, I was wrong, I was wrong, let go, let go."

"Are you still angry with me?" Liang Mimi twisted her teeth and grinded her teeth.

Tang Yu screamed louder and quickly begged for mercy: "I don't dare anymore, I don't dare anymore, sister, please spare me, my ears are going to be broken, my ears are going to be broken."

"Huh." Liang Mimi snorted coldly before letting go of her delicate hand, "I will be merciful and let you go this time. Next time, see how I deal with you."

Tang Yu covered his ears, quickly jumped behind his sister-in-law and eldest brother, stuck his head out, and glanced at Liang Mimi, "It's so violent, be careful no one wants it."

"Hey, you deserve a beating, right?" Liang Mimi rolled up her sleeves, intent on giving him a good beating.

Tang Yu quickly hid back, scared.

Luo Qing laughed shamelessly, leaned against Tang Yuan, and pulled out the person behind him: "You have the ability to support the fire, but don't be a coward if you have the ability, hahaha."

Tang Yu, Tang Yu looked at his sister-in-law longingly, looking weak, pitiful and helpless.

This caused everyone to give him a blank look.

They all forgot about Wen Kehan, whose face was congested and there were purple-red pinch marks on his neck, and who was thrown to the ground by Jiao Bo.

"Okay, I've laughed and made trouble, get ready and go back, you've been out for a long time." His goal was achieved, Luo Qing flipped up his hair and said.

Tang Yu's eyes suddenly widened: "It's been long enough? Didn't we just come out for a day?"

Because City B was worried about letting his sister-in-law come over from land, and no zombie birds had been found in the sky so far, so it was relatively safe, so they let them fly over.

It took a lot of time to explore the route on the road, but it only took four or five hours. Plus, now, it's not even a day, and: "Shouldn't we have a meal first? It's going to be five o'clock."

"You know how to eat, why didn't you get fat to death?" Leyak couldn't help complaining, "When we return to City B, are we worried that we won't have anything to eat for you?"

When people from other bases heard that Luo Qing said he was leaving, what's the point? They haven't bought the medicine yet.

"Dr. Luo, how can I exchange this potion?"

"Can we buy it now?"

"Dr. Luo, you said earlier that you could trade patents, right?"

Luo Qing nodded, "Indeed, you can directly exchange patents, but even if you have them, you probably won't be able to do it now."

"Why?"

Everyone relaxed and then became nervous. Why couldn't they make something concrete? This shouldn't be the case.

Is it because materials are scarce?

"Dr. Luo, don't worry about materials and equipment. We will do our best to find them when the time comes."

"Yes, yes."

Luo Qing shook his head, "It's not these problems, it's that there is something in it that is too hard and needs to be ground into powder. Today's machines cannot meet this requirement."

"Such a high hardness? I wonder what it is?"

"Ore?"

The group of people was very surprised. They were not ignorant people, but it was incredible to say that no machine could do it now.

Luo Qing didn't show off, and directly spit out two words: "Crystal core."

"ah."

Everyone looked at each other in shock. Crystal Core and the others were probably doing research in each of their bases, and they probably all failed in the first step.

I don't know what instrument to use to extract it, and I can't crush it.

"The crystal core is the core material of the antidote. It is said that the antidote must be found within ten steps of the poison. This is indeed true. When the crystal core is turned into powder and mixed with other ingredients, it can block the zombie virus and kill it completely." Luo

Qing explained to them, and when he said this, he sighed softly.

"It's just that it's not easy to turn into powder, which makes the cost very high. So whether you buy medicine or patents, we can't give you a cheaper price. I hope you can understand."

Tang Yu: ""

Doesn’t his brother have a handful of crystal core powder in his hand? Isn’t that just a pinch? It’s very difficult to get?

Reyak, Jiao Bo and others also had subtle expressions on their faces.

Staring at Luo Qing, his expression was very strange.

Then he looked at Tang Yuan, the silent crystal core powder making machine: ""

To say that it is not difficult to turn crystal nuclei into powder, it seems to be very difficult, because except for Tang Yuan, no one else can do it.

As for Dr. Luo, who can also do it, he cannot be called a human being, he should be called a god.

But it's hard to say, Tang Yuan can make hundreds of antidotes by kneading the crystal core for half an hour.

Just, for a moment I didn't know whether to say that Tang Yuan was too strong, or that they were just a bit useless.

Why.

Why were they the ones injured in the end?

People in other bases were quite prepared and thought it wouldn't be cheap when they heard it wouldn't be cheap.

The defective product that Hu Yifan made previously was priced at such a high price, and the product they sold was a mature product, so it would definitely not be low.

But, now they are facing a problem.

Do you want to buy potions, technology, or both at the same time?

Because they really can't turn the crystal nuclei into powder.

At least, not for the time being.

Compared with their entanglements, the people in base C are happy. They all belong to base B now and can receive it for free. They don't have those worries at all.

Everyone was smiling happily, making the other bases look envious and jealous.

"I don't know what we will trade with if we all buy it." The person in charge of G Base asked aloud.

Other base representatives pricked up their ears.

"There is no unique one for this." Luo Qing replied: "You can use enough crystal nuclei, or you can use equivalent patented results, or you can use special mutated plants and animals you found. It's all fine. We don't force it.

, a variety of choices.”

Luo Qing smiled and had a gentle expression, but he stepped on Hu Yifan and Wen Kehan ​​hard again.

They had to have those few things in order to exchange, and they were no different from bandits and robbers.

But they are different. They are humane and considerate, and they do it entirely on their own free will.

Several people breathed a sigh of relief. After knowing that the crystal core was the core of the antidote, they naturally thought that they could reduce the expenditure on the crystal core.

Luo Qing observed their expressions and continued: "The quantity we brought here this time is not large. The crystal core powder is too difficult to obtain, so I'm afraid we won't be able to trade you in large quantities."

After a pause, he said, "How about this? Each of your bases will buy five antidotes for use first, and then when you come to City B, we will sign a contract and purchase the patented ones directly. You can also bring one or two researchers here, and we will teach you step by step.

Avoid taking things back to base and making different results."
