The young man in front of me stood up somewhat awkwardly, his hands placed behind his back. He had a somewhat pleasing smile on his face as he said, "Brother, sister... Hello."

"Are you Chen Jiayang?" Lin Yan's hammer hung by his side, but his hand still gripped it tightly.

Initially, I thought this bold student should be tall and strong, but it turned out that his whole figure seemed somewhat weak when he stood up. His complexion was not very good, showing a slight pallor of malnutrition.

He nodded.

"Why were you sleeping here?" I was puzzled. After all, it was unsafe outside as long as we left the house. He dared to sleep in the fire escape.

"I... I was a bit scared," he said with some embarrassment. "Last night, I originally wanted to use a robot to pass things to you from the terrace, but I looked for a long time and didn't see you, so I came down and left them in the fire escape. I left a note for you..." As he spoke, he pointed to the instant noodles and water on the ground with his finger.

"Around three in the morning, I was still studying the robot when suddenly the power went out at home. I was very scared... So, I wanted to try my luck and see if you would come out."

"And then? When you met us, what did you want to do?"

"I wanted..." He paused, as if he had made a great determination before saying the second half of his sentence, "to be with you."

Lin Yan furrowed his brow and glanced at me upon hearing this.

"Didn't you say there was a lack of supplies? How did you get these?" I pointed to the supplies on the ground and asked.

He scratched his head. "Last week, my robot's functions were not yet perfected. I originally planned to wait for the robot to be perfected and then use it to go out and find supplies. But that day, I just couldn't hold on anymore... so I offended you, brother, and sister. The robot's functions were finally perfected yesterday morning, and in the afternoon, I tested it and controlled it to scavenge the remaining food and water from the nearest small supermarket warehouse."

"You made that robot yourself?" I was a little surprised and turned to look at Lin Yan, who also had a look of astonishment.

We had originally thought it was just an ordinary household robot.

"Yes."

"We need to consider this," Lin Yan said, pulling me back into the corridor and closing the door to the emergency exit.

At the moment Lin Yan closed the door, I caught a glimpse of the young man's bewildered expression and heard him lower his head as if he had done something wrong, looking a bit disappointed.

"What do you think?" Lin Yan asked me.

I pondered for a moment and replied, "Actually, I think it's possible."

"What's your reason?"

"I don't think he's lying. If he really has the ability to create robots and control them to search for supplies outside, then it would be very helpful to us."

Lin Yan also fell silent and contemplated for a moment. "Alright, I'll go with your decision."

The door to the fire escape opened again, and he still stood on the steps with his head down. When he heard the movement, he looked up with anticipation in his eyes.

"Do you... have anything to pack?" I asked.

His expression became joyful, nodding incessantly. "Yes! Yes! Brother, sister, wait a moment for me."

Saying that, he dashed up the stairs. After about ten minutes, he had two bulging travel backpacks on his shoulders and was still holding the robot that had already met us.

This little guy may look thin and weak, but he's quite strong.

He followed behind me into the corridor, with Lin Yan bringing up the rear, and the door to the fire escape was locked once again.
