transient stability

When Yang Fei came back, she brought two bottles of water and several packs of snacks. I asked her to sit on a bench by the side of the road, sweeping the floor and sweeping the gate with my corner of the eye.She looked at the phone for a while and then looked at me. I was uncomfortable being watched by her, and pointed to my bag.

Yang Fei seemed to understand, opened the bag, and took out the sketchbook.I saw her flipping through her notebook, and she finally calmed down for a while.

After about 10 minutes, Yang Fei came over with a notebook in her hand, "Shi'an, what is this drawing?"

She was referring to the draft of the sculpture I wanted to create this time, and I replied: "The devil on the tree, the angel under the tree." The fingertips of the two touched together, half of the devil was still in the chaos, struggling to open half of the wings.The opened half of the wings have turned into wings, as if purified by an angel.Under the angel's feet, half of his body was swallowed up by the black mud, more like a demon.

Yang Fei was surprised when she heard this, "Why did you draw this?"

"It's nothing, I just draw when I want to draw." I took the sketchbook, put it back in the bag and carried it on my back, "What time is it?"

"Well, it's 08:30."

My nerves tightened, and there was not much time left.If you can't go out before 09:30, the chance of running into Lin Qiu at the door will increase greatly.

Yang Fei seemed to see my anxiety, and asked concerned: "What's wrong with you, Shi'an? What's the matter?"

"It's okay, some want to go to the toilet."

"Pfft, you can go if you want, and no one told you to keep sweeping?" Yang Fei took my broom and started to sweep the floor.With my hands free, I really went to the toilet.It's absolutely true that people want to go to the bathroom when they're nervous.After the college entrance examination, I haven't felt this kind of nervousness for two years, and I am as excited as before the exam.

At [-]:[-]...the patients have all gone upstairs, and only Yang Fei and I are in the open space below.

"Shi'an, just now Aunt Liu sent a message asking me to help her find the key of her house. I don't know if it was left at the nurse's station. I'll go up for a while, are you okay by yourself?" Yang Fei looked at the phone and pressed the key. Said a few words to me.

"No problem, let's go. Is Aunt Liu coming over?" Aunt Liu is a nurse at the hospital. She took a night shift yesterday and went back early in the morning.I hesitated whether to ask Yang Fei to borrow her card, in case no one came in during this time, I could use her card to go out.

"Yes, she said that she was about to arrive at the hospital, and I'll come back as soon as I go." After Yang Fei finished talking to me, she went upstairs.

[-]:[-]...Yang Fei hasn't come down from the stairs yet, so I can't wait.

Suddenly there was a sound outside the gate, and a small electric car stopped, and the person on it was Aunt Liu.I also knew her, so I simply took the broom and went to the gate.

"Aunt Liu, why are you back? Are you here to pick up something?"

"Shi'an, why are you sweeping the floor?" Aunt Liu parked the car, rummaged through her bag, and took out the access control card.

My eyes lit up, and I restrained myself and said, "Yang Fei asked me to help with cleaning for a day, saying that Aunt Zhang asked for leave."

"Oh, yes, look at my memory, she just told me about it yesterday." I watched her open the door, and someone came in sideways.

"Aunt Liu, hurry up, Yang Fei said I found it." I smiled and let her pass through the gate sideways, reaching out and grabbing the railing.

"Hey, good." Aunt Liu didn't notice that I pulled the door behind her, I leaned the broom in the door, turned around and went out.The steel door was closed behind me, and I glanced through the door, just in time for Yang Fei to come downstairs.

I didn't think about it so much, and started running with my legs open, running dozens of meters in one breath.This section of the road was fine when I came, but today the road is being repaired, and the cars are all stopped on the long road. I have to walk a hundred meters to find a car.The night was long and dreamy, so he ran out quickly.I always have a bad premonition in my heart, and it is clearly not yet nine o'clock.

I ran more than 100 meters and finally reached the side of the road.It happened that there was a taxi in front of me, and the empty license plate was lit up, God help me!Someone seems to be unloading luggage at the back of the car. I just opened the passenger door and put a suitcase next to the open car back cover. A strand of long purple hair hangs down.

………Grass?Lin Qiu? !I didn't bother to get in the car, closed the door and ran out of the road.The taxi roared behind me and sped past in the same direction as me.

"Qin Shi'an?!"
