"I couldn't sleep, so I walked around on the bus. When I got to the very back, I saw an older man carrying a black box to the restroom. Then I saw him pressing the handle through the crack in the door."

The two policemen exchanged a glance, both sensing something unusual in each other's eyes. The older officer smiled at Tang Yue, "Yes, little Tang Yue is really great. We uncles know about this."

Do you still know which carriage you're in? You should go home now. Your family will be worried sick if they can't find you.

Tang Yue shook her head. "Uncle, is that uncle a bad person? Why did he go to the toilet to play with that black box? Couldn't he have played with it on the seat?"

The old policeman marveled at Tang Yue's keen insight at such a young age. "Well, Uncle doesn't know if he's a bad person, so Uncle needs to go check him out. Why don't you go back first?"

“I’ll take my uncle there; I know where he is.”

"no."

The young police officer firmly refused, his face serious.

Tang Yue didn't want to pay attention, but then she heard the old policeman say, "Little girl, what your uncle says is right. If the people there are bad, it could be dangerous. You'd better stay away from them."

If what the little girl said is true, then the matter is urgent, and they don't have time to say much more to her. A few minutes' delay could mean the leakage of national information.

The two of them stood up and left the cubicle, heading straight for the toilet in the last carriage.

Gu Yanxi was hiding in the cramped toilet. The telegram was almost finished; a few more taps and a complete report would be ready. But at the crucial last moment, the handle just wouldn't press down.

After several unsuccessful attempts, Gu Yanxi grew anxious. This was the restroom, and someone could knock on the door at any moment. He needed to hurry, but the door handle broke down at that crucial moment.

Gu Yanxi tried several more times, but no matter which direction he pressed, nothing happened, and he became somewhat discouraged.

However, the telegram was already nearly complete. Based on his years of intelligence experience, even if the last few characters weren't sent, the other side would know that something might have happened if they received the incomplete message.

They would then attempt to complete the telegram themselves. The final additions would be marked in a different way and await confirmation from leadership.

Thinking this, Gu Yanxi prepared to send it directly. However, when he pressed the send button, he was surprised to find that the send button was not working either. Gu Yanxi was now really anxious.

This message was urgent and important; he received it just as the train was about to depart. He didn't have time to complete it outside the station, so he had to find a way to send the message out on the train. But unexpectedly, the machine broke down at that crucial moment.

Left with no other option, Gu Yanxi could only dismantle the black box with his bare hands to see what was wrong inside. He inwardly sighed, realizing his previous efforts had been in vain.

Just as Gu Yanxi was disassembling the machine's casing to inspect its internal structure, there was a knock on the bathroom door.
