In the end of the world, I want to be the queen of zombies

After breakfast, Su Li went to the laboratory first to inspect the medicine refined by Huang Tiantian and others, and gave them on-site instruction and answered their questions.

They are very talented and have strong learning abilities. They can quickly master the knowledge taught by Su Li and apply it to other situations.

Of the 113 supernatural potions they refined yesterday, except for 4 that were slightly contaminated, the rest were all qualified.

This result is much better than Su Li expected.

"Ali, someone from Tianyuan Shelter wrote to us, requesting to buy 50 bottles of supernatural potions, and asked when it would be convenient for us to trade."

"Go to the switchboard and reply to their message. I just happen to have something to talk to you about."

Just as Su Li finished explaining the problem, a message from Zhou Shuyao popped up on the communication bracelet.

After reading the message, Su Li replied to Zhou Shuyao with a "good" and then said to Huang Tiantian, "Tiantian, I'm going to go out for a while. When I'm not around, you can find me through the communication bracelet."

Huang Tiantian nodded and said, "Okay, Senior Sister, you go ahead and do your work. Leave this to us."

Su Li habitually stroked the little Loli's green ponytail, then touched her head, and then turned around and went upstairs.

The little girl squinted her eyes in enjoyment and watched Su Li walk out of the laboratory. Then she skipped back to the operating table on her short legs.

"Ali, you're here."

As soon as Su Li walked into the laboratory, Zhou Shuyao immediately looked up and greeted her.

"You've come at the right time. Please help me try this."

As Zhou Shuyao spoke, she stuffed a fingernail-sized card into Su Li's hand.

Su Li looked at the small card of unknown material in her hand and asked in confusion, "What is this?"

Zhou Shuyao explained, "This is made from the rat king's claws. I cut it out with a laser cutter and processed it a little bit to make it what you see."

"I have done tests before. It can store and conduct the energy generated by super powers very well. It is a very good casting material."

"It's just that the material grade is not very high, and the raw materials are relatively rare."

Su Li held the card between her fingertips. "Is this the surprise you mentioned? Then how should I use this little thing?"

Zhou Shuyao said excitedly, "Didn't you say before? If you have the right materials, you can try to make a storage ring."

"Based on the characteristics, this is probably the material you need!"

Su Li was slightly stunned when she heard this, and then she immediately used space compression. After the internal space was formed, she controlled the force of space and transferred it to the small card at her fingertips.

After everything was done, Su Li took back her control with some anticipation.

Without Su Li's control, the compressed space that had originally overlapped with the small card instantly showed signs of collapse.

Under Su Li's somewhat disappointed gaze, the compressed space quickly decomposed from the periphery to the center, and in a short while, most of it had collapsed.

"Can't you?"

Just when Su Li thought she was going to fail, the speed of the space collapse began to slow down and then stopped completely.

The small part of space that did not collapse turned into silver light and was successfully integrated into the small card.

Su Li sensed it and found that a small space of about 5 cubic meters suddenly appeared in this small card.

Zhou Shuyao asked nervously, "How is it? Is it okay?"

Su Li handed the small card to her and said happily, "It's half successful. It can indeed be used as a storage device, but the space is a bit small.

Zhou Shuyao also sensed it and instantly discovered the space in the card. She smiled and said, "For you, it must be very small, but for others, it is already very large."

"And the reason why it has a small internal space is because the material grade is relatively low. The card itself is also small, so it can hold less energy."

"When we have more advanced materials in the future, the storage space will naturally become larger."

Su Li nodded, and then asked in confusion, "Then why not just make the card bigger?"

Zhou Shuyao explained, "Because these cards are to be embedded in the communication bracelet and used as functional molds, they cannot be made too big."

"And we don't have enough materials. If the size of a single card gets bigger, then the number of cards will naturally decrease."

"Even if the cards are made this small, with the materials we have now, we can only make about 20 cards at most. We can't equip everyone with them, so we can only provide them to key people first."

Su Li asked in surprise, "The Rat King's claws are so big, can only twenty be made?"

Zhou Shuyao pinched Su Li's face unhappily, "You don't think that the claw can be used after it is cut off?"

"The only useful thing in the claws is the superconducting component inside. This requires repeated processing, screening, purification, and finally synthesis."

Su Li showed a flattering smile and hugged Zhou Shuyao's arm, "Although I don't quite understand what Yaoyao said, but I know that my golden retriever Yaoyao is super powerful."

Zhou Shuyao grabbed Su Li's ears and whispered in her ear, "It's good for my white-haired Ali to know."

"Okay, since you're being cute and coquettish, I'll forgive you. If you have other materials in the future, remember to bring them back for me."

Su Li nodded repeatedly, "Of course, of course."

Zhou Shuyao lowered her head, sniffed Su Li's neck, and said jokingly, "Oh, you smell like a deer all over."

"Did you eat the cutie last night?"

Su Li's expression froze, and she pretended to be nonchalant and said, "What do you mean you ate the little cutie? New humans don't eat people, and of course I don't eat them either."

What the hell?

Can this kind of thing be brought up and talked about directly?

Su Li complained silently in her heart.

Zhou Shuyao chuckled twice, "I knew you were a heartless little kid. You took advantage of everything and you still don't dare to admit it."

"Okay, remember to be nice to the little cutie next time. Such a cute little girl, I can't bear to see her sad."

Zhou Shuyao finished speaking, walked to the workbench, and handed a small box to Su Li. "Let's deal with these cards first. I'll go back to the villa at noon and put the cards into their communication bracelets."

"Card Card, that sounds a bit old-fashioned, how about we give it a name?"

"Let's just call it a storage card. What do you think, Ali?"

Su Li took the small box and said without hesitation, "Well, let's call it a storage card. It's a good name."

"By the way, can you put a lock on the storage card? So that it can only be used by designated people."

Although the space power in the storage card was left by Su Li, she was only a user of the space power, not the master of the space power, so she could not make it complete operations like recognizing the master.

Zhou Shuyao thought about it, shook her head and said, "Not for now, I'll think of a solution later."
