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

late at night.

Jiang Zhiyu had calculated the time difference correctly this time, and landed right in her own courtyard.

The lights were still on inside the house.

Just as Jiang Zhiyu was about to lift her foot, the door to the room creaked open. Song Yanzhou, wearing only an old sweater and with slightly disheveled hair, rushed out. Upon recognizing her, his face instantly lit up.

He strode over and pulled the person into his arms.

"daughter in law."

Jiang Zhiyu was lifted so high that her toes almost left the ground.

"Wife," Song Yanzhou called again, his voice trembling without him even realizing it, "you really didn't lie to me, you're back in less than three days."

He carried her around the yard three times before stopping. Jiang Zhiyu was a little dizzy from being spun around, so she reached out and patted his back.

"Put it down, put it down! You've practically worn the whole courtyard out of shape!"

Song Yanzhou reluctantly put her down and quickly grabbed her arm.

"Are you tired? Are you hungry? Shall I make you a bowl of noodles?"

"I'm not hungry."

"Aren't you hungry?"

"I'm not hungry at all," Jiang Zhiyu said with a smile, pushing him towards the house. "I ate before coming back."

Although the white food wasn't very good, she had plenty of food stored in her space, so she really didn't skimp on herself.

Upon entering the room, a wave of warmth washed over them. Song Yanzhou pulled her to sit on the edge of the bed and knelt down to take off her shoes.

Jiang Zhiyu reached out to stop her.

"I can do it myself."

"You sit down."

Jiang Zhiyu didn't stop him anymore and let him do what he was doing.

"By the way, honey, Commander Qian has been looking for you everywhere these past few days."

"Mr. Qian? Oh! Then I know what happened."

"The phone rang yesterday from Beijing; Senior Zhuge was also there."

Jiang Zhiyu nodded.

"Okay, I'll go there tomorrow morning."

"So urgent?"

"It's extremely urgent, you know what the rest is."

Song Yanzhou didn't ask any more questions and put her hand back under the covers.

"Go to sleep now, we have important things to do tomorrow."

Jiang Zhiyu hummed in agreement and closed her eyes.

……

As dawn broke, Song Yanzhou had already set breakfast on the table.

Millet porridge, fried eggs, pickles, and a small dish of sliced ​​sausage. Jiang Zhiyu finished her porridge, wiped her mouth, and got up to walk into the courtyard. Song Yanzhou saw her to the door.

"When will you be back?"

"We'll see!"

"It depends; it's not certain."

Jiang Zhiyu chuckled at his remark and tiptoed to rub her chin against his.

"I'll try to squeeze in one more time within three days, okay?"

"OK."

Jiang Zhiyu turned around and disappeared from sight.

……

Beijing Second Administration Bureau.

When Jiang Zhiyu landed, she landed right there.

After walking through two corridors, I pushed open the door to the director's office, and the two people inside looked up at the same time.

Zhuge Yunhe put down his pen.

Commander Qian jumped up from his chair.

"Hey, Comrade Jiang!" General Manager Qian strode over, "I've been looking for you so long I've turned a few hairs gray! You've finally shown up!"

Jiang Zhiyu smiled and invited him to sit down.

"Don't worry, Mr. Qian, everything is here."

"You have no idea, batches of scientists have gone there. We've made three trips to pick them up at the train station. Everyone's arrived, the equipment's been moved in, and they're all just waiting for your copy. If you disappear like this, all of us in this room will be stuck in the lab every day, staring blankly."

"Do you still have the list?"

"I kept it, it's just sitting on my office desk."

"That list can be thrown away."

Mr. Qian was taken aback.

"Throw it away?"

"That list is from ages ago," Jiang Zhiyu said with a mysterious smile. "What we have now is far more than what was on that list."

Mr. Qian's eyes lit up instantly.

He's a construction worker; he may be rough around the edges, but his intuition is sharp. He instantly grasped the weight behind those words. The old man's eyes reddened on the spot, and tears streamed down his face as he wiped them away.

"Oh God bless my China!"

Zhuge Yunhe watched from the side without saying a word.

Mr. Qian grabbed Jiang Zhiyu's hand, his voice trembling.

"Then what are we waiting for? Let's go now!"

"You go first," Jiang Zhiyu said, pulling her hand back. "I'll be there shortly."

"Then?"

"I might have arrived even before you," Jiang Zhiyu blinked. "Why don't you go call and clear the area first, or follow the usual procedure?"

Mr. Qian slapped his forehead.

"Yes, yes, clear the area, clear the area, the usual procedure, I'll go right now."

He hurriedly grabbed his military overcoat and was about to rush outside, but turned back at the door.

"Old Zhuge, I'm outta here!"

"Go ahead, go ahead."

Mr. Qian's footsteps faded into the distance down the corridor. The room fell silent.

Zhuge Yunhe slowly began to speak.

"The old leader left instructions before he left: everything must be returned cleanly and neatly, so that no one can find out the truth."

Jiang Zhiyu nodded.

"I remember."

Jiang Zhiyu's heart was suddenly struck by something.

She looked down at her hands, which were empty. These past few days in the US and Europe, she had been busy with one thing after another, as if she were trying to bury herself in those secret rooms, basements, and museums. She knew exactly what she was hiding from.

But at this moment, Old Zhuge's words pulled her back to reality.

Zhuge Yunhe had already stood up and walked over to gently pat her shoulder.

"Getting down to business is the priority. Once the equipment is delivered, let the people below get to work as soon as possible. That way, the old leader can rest assured."

"Um."

"Go."

Jiang Zhiyu took a deep breath, looked up, and the emotion in her eyes had completely disappeared.

"Then I'll be going."

……

When she landed again, Jiang Zhiyu stood at the underground entrance of the experimental base.

Mr. Qian's call came quickly, as expected. The entire base was silent; all the guards had retreated to the outer perimeter, and not a single person could be seen inside. Jiang Zhiyu continued walking downhill.

The first floor, the second floor, the third floor... the further she went, the wider her eyes opened.

Six underground floors, all empty.

That wasn't a laboratory; it was an entire underground city. The load-bearing pillars were so thick that two people couldn't encircle them, and the domes were so high that they could make you dizzy if you looked closely. Each floor was divided into several areas, with ventilation, water pipes, and cables all running along the ceiling, and the walls were painted with a moisture-proof milky white paint. There wasn't a trace of moisture in the air, only a faint smell of new walls.

Seventeen peeked out from her sleeve, and the blue crystal remained bright for a long time before she recovered.

"Host."

"Um."

"The people of this country are truly magnificent," Seventeen's mechanical voice trembled slightly. "This project, spanning over six months, they actually completed it under such conditions."

Jiang Zhiyu didn't say anything, but slowly walked to the load-bearing column and touched the cold cement with her hand.

At that moment, she suddenly understood why her former leader had placed her in this position with such confidence.

She withdrew her hand and took a deep breath.

Seventeen.

"exist."

"start."

Seventeen's wings unfurled with a "whoosh," and the blue crystals suddenly shone so brightly they were blinding.

On the basement level, dozens of large, precision instruments materialized from the air, neatly arranged in designated areas. The second floor housed various precision electronic devices, microscopic systems, and spectroscopic instruments. The third floor contained a range of metallurgical, materials, and chemical analysis facilities, each one landing on the floor with a dull tremor.

After stacking the three layers, Jiang Zhiyu stopped.

Seventeen looked at her with some confusion.

"Host, I've removed all the identifiable parts from this batch of equipment! Even if scientists from Country M stood right in front of it, they wouldn't recognize it as their country's equipment."

"Well done! It would be troublesome if scientists from other countries really infiltrated," Jiang Zhiyu clapped her hands.

"Alright! What I've given them is enough for them to study for several years. The rest they can work their way up step by step on their own."

Jiang Zhiyu walked to the top of the stairs, looked back at the three heavy layers of equipment behind her, and nodded in satisfaction.

"They're gone, Seventeen."
