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

As the day of departure drew closer, the atmosphere in the Su family changed.

The most obvious example is Grandma Shen Peiyu. After taking care of herself for a while, she was in much better spirits and had more smiles on her face. But whenever Jiang Zhiyu was mentioned leaving, her rosy complexion immediately dimmed and her eyes would easily turn red.

"Yuyu, can't you stay a few more days?" Shen Peiyu held her hand, asking again and again, "Grandma doesn't want you to leave..."

Jiang Zhiyu was also upset, but she knew she couldn't stay in the US forever. There were still so many things waiting for her to do back home, so many things waiting for her to hand over.

She gently patted her grandmother's hand, her voice soft yet firm: "Grandma, I will definitely come again. Within the next two years, I will definitely go back to M country to see you, and then I will take you back to China to visit the Su family's old house and see my mother."

"Really?" Shen Peiyu's eyes lit up.

"Really," Jiang Zhiyu nodded solemnly, "I assure you."

Shen Peiyu was slightly relieved, but still held her hand tightly and repeatedly told her to be careful on the road, to call and let her know she was safe when she arrived in China, and to contact her uncle anytime if she needed anything.

Su Lixing stood to the side, also looking reluctant to part. He had only known his niece for less than a month, and he already adored her. She was smart, capable, and sensible, and she looked so much like his sister Wanqing. Every time he saw her, it was like seeing Wanqing when she was young.

He Li's eyes also reddened. She held Jiang Zhiyu's hand and gave her instructions all the way, explaining everything from food and clothing to accommodation and transportation in great detail.

Su Wenhao, however, had a long face ever since he learned that Jiang Zhiyu was leaving, as if someone owed him eight million.

He stood in the corner of the living room, arms crossed, lips pursed, eyes red, stubbornly refusing to let tears fall.

"Wenhao, what's wrong?" He Li glanced at him and asked helplessly.

"I'm fine!" Su Wenhao said in a muffled voice, his nose red. "I'm just unhappy! I finally have such a beautiful and presentable younger sister, and she's leaving before I've even had enough time to play with her! How long has she been here? Less than a month! A month! Other people's cousins ​​stay for at least half a year!"

As he spoke, his voice grew increasingly choked with emotion. Finally, unable to hold back any longer, he abruptly turned around, his shoulders trembling.

"I can't bear to see Yuyu go..."

Seeing him like this, Jiang Zhiyu felt a mix of sadness and warmth in her heart. She stepped forward and gently patted his shoulder: "Little cousin, it's not like I'm not coming back. Didn't I say I'd definitely come see you again in the next two years? Then you can take me out to play again, okay?"

Su Wenhao sniffed, turned his head, his eyes red-rimmed, and looked at her, saying in a muffled voice, "You mean what you say?"

"I promise." Jiang Zhiyu smiled and held up her little finger. "Pinky promise."

Su Wenhao was stunned for a moment, then reached out his hand, made a pinky promise with her, and pressed his hand firmly to make a mark.

"Then you mustn't forget," he said, his voice choked with emotion, "I'll be waiting for you."

Jiang Zhiyu nodded, her throat tightening slightly.

She blinked hard, suppressing the tears welling up in her eyes.

Even though she was reluctant to leave, she had to go.

Su Wenhao wiped his face, forcing back his tears. Suddenly remembering something, he grabbed Jiang Zhiyu's wrist: "Come on! Since you're leaving, your little cousin will take you out for one last good meal! Last time we were so busy visiting the zoo, I didn't get to properly take you to see the good food in San Francisco!"

Before Jiang Zhiyu could react, he dragged her out the door.

Su Lixing called out from behind, "Drive slowly!" Su Wenhao waved without turning around, hopped on his motorcycle, and shoved a helmet into Jiang Zhiyu's hand: "Hold on tight, I'm taking you to eat all the good food in San Francisco today!"

The motorcycle sped off in a flash.

The two went to Fisherman's Wharf first. The wharf was bustling with activity, the air filled with the aroma of sea breeze and butter. Su Wenhao, familiar with the place, led her straight to the stall with the longest line: "This! San Francisco's most famous sourdough clam chowder! You absolutely have to try it!"

The rich soup was served in a hollowed-out sourdough bowl. The golden bread crust exuded the aroma of wheat, while the clam chowder inside was milky white and thick. One sip was both fresh and warming, and Jiang Zhiyu couldn't help but squint her eyes.

"Delicious, isn't it?" Su Wenhao raised an eyebrow smugly. "I knew it! Here, take this!"

He was like a feeding machine, dragging her to buy fish and chips. The crispy fish fillets dipped in tartar sauce were crispy on the outside and tender on the inside. Next came grilled crab legs, the aroma of garlic and butter filling her nostrils. There was also handmade pizza from the Italian section, with a thin crust and crispy edges, and long strands of cheese stretching out with every bite. They didn't even miss the Mexican burritos, with beef and guacamole, a big, heavy burrito in their hands.

Jiang Zhiyu doesn't usually eat much, but Su Wenhao, her "food guide," was so enthusiastic that he forced her to try everything. The two of them walked and ate along the street, from Fisherman's Wharf all the way to Chinatown, finally stopping in Chinatown with a bowl of hot mango pomelo sago.

"How is it? Isn't it delicious in San Francisco?" Su Wenhao said proudly.

"Delicious," Jiang Zhiyu said sincerely, a little sugar syrup on the corner of her mouth. "Everything is delicious."

In the apocalypse, let alone these things, being able to eat a piece of unspoiled canned food was like celebrating the New Year. Now, being able to stand peacefully on the street, enjoying the sea breeze and eating hot food, this simple happiness is more precious than anything else.

After finishing their meal, Jiang Zhiyu told Su Wenhao to go home first, saying she still had some things to buy.

Su Wenhao wanted to go with her, but she stopped him with, "Cousin, why don't you go back and keep Grandpa and Grandma company? I'll be back as soon as I buy some things."

Jiang Zhiyu took a taxi to Sam's Club by herself.

This has become a habit of hers since she came to the United States: before leaving a place, she always goes on a shopping spree in the local supermarkets.

Sam's Club had a wide variety of goods, and she pushed her shopping cart, buying as she went—rice, flour, cooking oil, various canned goods, frozen food, instant noodles, chocolate, coffee beans, milk powder, dehydrated vegetable packs... Grains and food items were the most basic; she knew best what hunger felt like in the apocalypse. Bringing these things back would not only improve her parents' lives but also allow her to replenish supplies for the border guards through Commander Li.

Next was the seed section—vegetable seeds, fruit seeds, grain seeds—I took several large bags of each type. The variety of seeds available domestically is too limited; these improved seeds, if taken back, can significantly boost domestic grain production.

They even included everyday items—toothpaste, soap, laundry detergent, hygiene products, sewing kits, button batteries… Don’t underestimate these seemingly insignificant little things; they are highly sought-after items in China, and you might not be able to buy them even if you have the money.

When Jiang Zhiyu pushed her three shopping carts, piled high like a small mountain, to the checkout, the cashier's expression was priceless. She paid without batting an eye, stored everything in her spatial storage, and then calmly walked out of the supermarket.

When they returned to the Su family home, it was already dark. As soon as Shen Peiyu saw her, she immediately pulled her to sit down and eat, and put two more pieces of pork ribs into her bowl.

Looking at the table full of dishes and her family sitting together, Jiang Zhiyu felt a little reluctant to leave.

But then I thought about the things I was going to bring back home, and I felt a secret thrill. It was such a conflicting feeling!
