With three superpowers at his fingertips, he could dominate the 1970s.

As dawn broke, the quiet carriage gradually came to life. Xiao Li, clutching the note written by Old Zhao, hurried off to find the train police, while Xiao Wang stood guard at the compartment door, his back ramrod straight.

Old Zhao took out a coarse cloth bag from his suitcase, opened it layer by layer, and inside were several hearty coarse grain cakes and a small bag of refreshing pickled vegetables. He smiled and pushed the bag towards Jiang Zhiyu, his tone kind: "Comrade Jiang, try this. My wife made it by hand. It'll fill you up."

Jiang Zhiyu didn't hesitate and took a bite of a whole-grain pancake. The distinct grains of the whole grain had a faint wheat aroma, and the taste was much better than she had expected. She then took out a scallion pancake made by Aunt Li from her bag, peeled a hard-boiled egg, and handed it over: "Old Zhao, you should try this too. My aunt's scallion pancakes are especially delicious."

The golden-brown pancakes emitted a rich aroma of scallions, and Old Zhao's eyes lit up instantly. He nodded repeatedly, "Great! Great! We're in for a treat today!" He took the pancake, took a big bite, chewed, and then squinted his eyes in satisfaction, praising sincerely, "This cooking is far superior to my old woman's!"

The two were enjoying their meal when there was a gentle knock on the door of their compartment, and the train conductor entered with a police officer.

The train conductor was a slightly overweight middle-aged man with a smile on his face, but his eyes were like radar. While gently inquiring about Old Zhao's attack the previous night, his gaze would occasionally sweep over Jiang Zhiyu with a mixture of curiosity and suspicion. Old Zhao's status was indeed special; he had to be extra careful around anyone who appeared near him. If something happened to someone on his train, he wouldn't need to keep his job.

Jiang Zhiyu felt uncomfortable from his furtive glances, so she put down the pancake in her hand, raised an eyebrow and said bluntly, "If you have something to say, just say it. If you keep glancing like that, be careful your eyes will become crooked and you won't be able to straighten them."

"Pfft—" Old Zhao couldn't help but laugh out loud, and the tense atmosphere in the private room instantly relaxed a lot.

The train conductor blushed and coughed awkwardly twice, "I'm so sorry, Comrade Jiang, it's just that last night's events were too strange..." He cleared his throat, put aside his ulterior motives, and asked seriously, "Old Zhao, could you please describe the situation in more detail? What were the dark figures wearing? Were there any obvious distinguishing features?"

Old Zhao patiently recounted the incident again, emphasizing Jiang Zhiyu's intervention: "We owe it all to Comrade Jiang this time; otherwise, my old bones and the two guards would probably be dead here."

The train police officer beside her was quickly taking notes, glancing up at Jiang Zhiyu every now and then. Finally, unable to contain his curiosity, he asked, "Comrade Jiang, I heard from Comrade Li that you have an antidote? Are you perhaps a medical student?"

"No," Jiang Zhiyu said calmly, without the slightest ripple of emotion. "It just so happens that we had the antidote. This medicine can cure many poisons, but don't ask about its origin. The recipe has long been lost, and some of the ingredients have become extinct. Saving them was merely a matter of chance."

She spoke bluntly, leaving no room for further questioning. The train conductor and the police officer exchanged a glance, both seeing helplessness in each other's eyes. They knew that further questioning would not yield any answers, so they repeatedly reminded everyone to be careful before turning and leaving.

The door to the private room slowly closed, and the room returned to silence. Old Zhao looked at Jiang Zhiyu, a smile in his eyes: "You're a straightforward girl, you never beat around the bush."

"Beating around the bush is too much trouble, it's unnecessary." Jiang Zhiyu picked up her water glass, took a sip of warm water, and smoothly changed the subject, "Professor Zhao, you do geological research, it must be very hard running around in the field all year round!"

"Yes, I've spent most of my life on field research." Old Zhao couldn't help but sigh. "When I was young, I spent three whole years in the Gobi Desert and also ventured into the deep forests of Changbai Mountain. I've tasted all kinds of hardships..." He rambled on about the interesting stories from his past research trips, and Jiang Zhiyu listened with great interest.

In the afternoon, the same train police officer returned to the compartment, his face grave. "Mr. Zhao," he said, "we suspect this is a deliberate act by spies. We've thoroughly searched the entire train, but we haven't found any trace of the man in black. He's either hiding somewhere or jumped off the train midway. Please don't leave your compartment. We've increased the number of officers patrolling."

After saying that, he looked at Jiang Zhiyu with a hint of expectation in his eyes: "Young lady, I can tell you're not simple. Please take good care of Old Zhao. Once this matter is completely resolved, I will definitely send an official letter of commendation to the place where you went to work in the countryside."

Jiang Zhiyu's eyes lit up. Although she wasn't entirely familiar with the rules of this era, she knew the weight of this letter of commendation. In an era where everything valued background and reputation, a letter of commendation from the railway authorities was enough to make her stand out in the countryside and save her a lot of unnecessary trouble.

"Okay, I promise you." She nodded readily. "I'll keep a close eye on things."

Having received a reply, the train police officer left with peace of mind. For the rest of the day, the carriage was unusually quiet, with only the rhythmic, muffled clatter of the wheels rolling over the rails.

Xiao Li and Xiao Wang took turns on duty, while Old Zhao occasionally flipped through geological atlases. Jiang Zhiyu leaned against her bunk with her eyes closed, resting, but secretly thinking to herself: In another day, we will reach the Northeast. I wonder how my parents are doing now.

As night fell, Jiang Zhiyu, who had been cooped up on the train for two days, couldn't sit still any longer. Unable to properly wash and shower, and only able to sneak a few bites of the delicious food in her space, she felt incredibly uncomfortable. She greeted Old Zhao, saying she needed to use the restroom, and got up to leave.

The bathroom was empty, and Jiang Zhiyu quickly slipped into the space. Steam rose from the spiritual spring pool, and on the stone table beside it were roast meats and milk tea she'd brought back from Hong Kong. She wolfed down half a roast goose, then took a comfortable hot bath, and even brushed her teeth. In this era of scarcity, these people's noses were like radar; the whole process took no more than ten minutes. Afraid someone might be waiting outside, she quickly changed into clean clothes and left the space.

As soon as she pushed open the bathroom door, she bumped into a girl with two braids. The girl was first taken aback by Jiang Zhiyu's appearance, then her eyes welled up with intense jealousy. She snorted coldly, turned around, and went into the bathroom.

Jiang Zhiyu didn't care at all; she never bothered to think about such insignificant people.

On the way to the private room, 0047 suddenly cried out urgently in her mind: "[Host, there's something wrong with the woman holding the child in the third row! The child has been given a strong sedative; the smell is extremely strong. If we delay any longer, it might damage his mind, and in severe cases, he might become mentally impaired.]"

Jiang Zhiyu paused slightly, glancing discreetly at the third row. There she saw a woman in a blue cloth jacket, holding a child who was dozing off with his head down. The child was wrapped up tightly, with only a few strands of soft hair showing, and remained completely still throughout.

Just then, a bald man in the back row suddenly looked up, glaring at her fiercely with a blatant warning in his eyes.

Jiang Zhiyu instantly realized: these two were in cahoots.

She walked back to the compartment without changing her expression, and only after closing the door did she say in a deep voice, "Mr. Zhao, there is a woman in the third row of the ninth carriage. The child in her arms has been drugged. The smell of the drug is very strong. The child must have been abducted."

"What?" Old Zhao's face suddenly darkened, his tone serious. "Are you sure?"

"I've had a sensitive nose since I was a child, and I'm especially sensitive to the smell of medicine, so I can't be wrong," Jiang Zhiyu explained, half-jokingly. "That child hasn't shown any signs of life yet, so the situation is probably not good."

Upon hearing this, Xiao Wang immediately stood up, his tone firm: "I'll go find the train police right away!"

"Remember to be careful, and don't alert them," Old Zhao solemnly warned.

Xiao Li then walked to the door of the private room. The series of unexpected events had him tense up, ready to deal with any emergencies at any time.

Jiang Zhiyu didn't say anything more. All she could do was offer a timely reminder; handling the aftermath was the duty of the train police. The train would arrive in one more night, and she didn't want to cause any more trouble. At that moment, she was filled with anticipation to see her parents as soon as possible.

Not long after, Xiao Wang returned with two train police officers. They tiptoed towards the third row of seats, and soon the sounds of arguing, mixed with the faint cries of a child, filled the air. Jiang Zhiyu listened quietly through the door, knowing the matter had been resolved, and her anxiety subsided.

Silence returned to the private room. Old Zhao looked at Jiang Zhiyu with increasingly gentle eyes: "You, young lady, are not only straightforward, but also so thoughtful and kind."

Jiang Zhiyu didn't reply, but turned to look out the window. In the deep night, the scattered lights of the distant village flickered on and off, like scattered stars, radiating a touch of warmth in the darkness.

"We're almost there," she murmured, her voice filled with barely concealed anticipation.

Old Zhao smiled and didn't say anything more to disturb him.

The next morning, the train finally entered the Northeast. The scenery outside the window gradually lost its greenery, becoming desolate and vast. The flat fields turned into a vast wasteland, and the distant mountains were covered with a thin layer of snow. Even the air that rushed in carried a biting chill.

Jiang Zhiyu took out a thicker coat from her luggage and put it on, but her heart was burning even hotter, feeling a little nervous and a little expectant.
