Xia Mi hasn't woken up yet, and Li Su is already busy here. He looked at the round orb in his hand and smiled with relief on his face.

The initial idea was abandoned. Uranium-235 has radiation, I don't know what to do with integrated circuits, the half-life of the new element is too short, and it's better to think about it.

What he has in his hand is a lump of elemental, elemental silicon. It is not difficult to refine elemental silicon, what is really difficult is that it is a "round" ball.

What we usually call round things is not actually round, they are all irregular objects. The roundest "ball" in the world so far is probably the silicon element ball made by the "Avogadro" project in 08 in order to define "1 kilogram" more accurately. "If you can blow our sphere to the size of the Earth, you will see small ripples of about 12 to 15 millimeters on a smooth sphere with a circumferential error of only 3 to 5 meters," the person said. ”

But this is only the limit of what humans can reach, and it is not really a "sphere". Even so, the United Nations spent more than a million euros on this gadget, which is less than ten centimeters in diameter. At this moment, the real "sphere" was lying quietly on Li Su's hand, formed by the accumulation of silicon atoms on its own, and it only took more than ten minutes.

Appreciating the beautiful luster of silicon element, Li Su returned to the real world.

Appearing in a familiar room, Li Su picked up the clock on the bedside table and looked at it twice. Fortunately, it's only been more than two hours, and it's not too late to rush back.

It's just that something seems wrong.

Suddenly, he reacted, staring wide-eyed at the empty palm.

Where's my ball?

What about such a big ball?

？？？

Li Su disappeared and reappeared again, still with a hellish expression.

I can't bring anything that was made over there!!

Gan!

Before he could go crazy, Li Su suddenly realized another problem.

The elements that heal Natsumi were all made by him, plus Natsumi is now just an ordinary half-blood......

Looks like it's time to prepare a nutritious meal......

Scratching his head, Li Su was ready to let it go first. Anyway, it's all for later, and I'll think about it later.

After taking away the key card, Li Su left the hotel and returned to Xidan.

The elevator has been back in operation. It seems that the earthquake warning has been lifted, and people who have come out to take refuge have returned to their rooms. Li Su walked against the flow of people, passed by the guests, and walked out of the lobby onto the street.

After all, it was only a small earthquake, and the damage was not great except for the Xidan Wedding Building, and this thousand-year-old city had already returned to its usual rectification. Men and women in suits and ties returned to their posts, writing programs for those who wrote programs, made documents for documents, held meetings for meetings, and made drawings in an orderly manner.

The park was also noisy. The Tai Chi of the old people and the skateboards under the feet of the young people complement each other, and a few young people set up their easels not far away, and this place is once again transformed into a place of relaxation.

Returning along the way he came, Li Su soon saw his destination—probably the only ruin in the entire city of Beijing. It seems that the swarm of stomaths affected the structure of the building, and the building collapsed shortly after his departure. A red cross chess piece was planted on the ruins, and several white tents were propped up next to it.

But none of the protagonists of the earthquake were in tents. They stayed by the rubble, each with a police coat draped over their shoulders, and it appeared that they had been rescued. The most conspicuous of them all, Caesar, was leaning against a broken wall, frowning and munching on a croissant, and holding Nono in a bright red dress in his left hand. Nono pinched half a bun in his hand and was looking at Fingal next to him with a look of refusal, and Fingal, who was leaning on the same wall, had a silver sword expression.

Lu Mingfei squatted in the corner on the other side, nibbling on the meat bun while looking at the others. Chu Zihang was lying on the stretcher next to his feet, he was tied into a zongzi with gauze, his eyes were blank, Qin Nai was standing on the other side of Chu Zihang, and there was also a bun in his hand.

"Yo!" Li Su waved his hand to everyone.

"Why is it so long?" Kotono was visibly happy to see Li Su appear.

"Lost." Li Su hugged her, and before she could speak, she felt her shoulders sink. Looking back, a young man wearing a "volunteer" armband also put a police coat on him, patted him on the shoulder affectionately, and then pointed to the tent on the side, "You were just dug up, right?" Let's get a physical check-up first. ”

Li Su was confused. Just as he was about to explain that he had just come, he inadvertently saw himself through the reflection of the glass door.

Messy hair, a shirt full of wrinkles, and dust that is especially noticeable at the joints...... Well, it does look like it has just been gouged out......

"I don't need to check it, where can I get the food?" I reached out and brushed my hair, and as soon as my hand loosened my stiff hair, it stubbornly returned to shape. After two attempts, he gave up and let his hair stand in a mess.

"On the other side of the tent." The volunteer brother looked at it and felt that Li Su was in a good state of mind, so he didn't force it, and after answering his question, he hurried to the next place where he needed help.

In the past, I also got a bun in the queue, and Li Su turned back and squatted in the corner with everyone to have breakfast. Before the buns were finished, there was a sudden noise in front of them, and a moment later a group of people walked into the medical point with long guns and short cannons, and at the front was a woman with a microphone. This circle of people is not bad at Chinese, and they can understand what she is saying.

"Hello everyone, this is the reporter Yang Ting in front, and now we have arrived at the Xidan Wedding Building, which was the most severely affected by this earthquake. Through the lens, you can see that the Xidan Wedding Building has collapsed, and the relevant departments have begun to search for and rescue the survivors and provide medical assistance......"

The cameraman's camera flickered to this side, and the interview team disappeared into the white tent, apparently to interview the person in charge of the operation.

After eating the buns, Li Su's mobile phone suddenly rang, and when he touched it, he saw that it was the principal calling.

"Hello?! We've got it, Headmaster Angers. Li Su answered the phone and reported the results directly, thinking that this must be what he is most concerned about.

"I know." The headmaster wasn't surprised. "Beijing's ground movement data has flattened out a lot, and I know you've got it done. Now, turn on Hands-Free. ”

Li Su turned on the speakerphone and pointed the speaker towards everyone so that everyone could hear it clearly.

"Now I announce the task assigned by the Vice-Chancellor." Ange's voice was still so flat.

"Vice Chancellor? Night watchman? Caesar stood up straight, and his face was much more solemn.

"Well, now you all go sweep the floor."

“What？” The bend was a bit sharp, and everyone almost didn't turn around.

"We saw from the surveillance system that the scythe seemed to have turned into dust, and the vice-principal said that these things have a lot to do with alchemy, and I hope you can collect as much as possible." Ange sighed, "And it's not just us who covet these things, other half-blood families have also gotten the news, and we have no reason to keep them to ourselves, so I hope you can collect them as much as you can before they arrive." ”

"Okay." Knowing the importance of the task, Caesar didn't mind being a cleaner.

"The equipment has been delivered by helicopter and access to the subway tunnel has been requested. Come on, guys. ”
