In my 40s, the trading system took me flying

Old Mrs. Xu clapped her hands and said, "Yes, that's exactly what I said! Look at you two adults, you're not as sensible as a baby!"

When Haizi's wife saw Haizi being beaten, she went up to pull Old Lady Xu away, but was stopped by Haizi.

"I deserve to be beaten by my Second Aunt, so don't get involved!"

Haizi was not completely heartless. When he was cleaning up just now, he saw the environment his mother had been living in, and the emotions that had always been ignored emerged.

He then realized that his wife had always been hypocritical in front of him and had never really taken good care of her mother.

After Haizi finished yelling, he knelt in front of his mother.

"Mom, I was wrong. I will definitely respect you well in the future!"

His mother shed tears silently and didn't want to say a word.

Old Lady Xu kicked Haizi and said, "You didn't know how to show filial piety before, but you will learn how to do it in the future?"

Haizi made repeated assurances, but Old Lady Xu didn't believe him. At her age, she actually cherishes family affection even more. She couldn't bear to see her sister living such a miserable life.

"I'll take your mother back to live with her for a while. When she recovers, you can come and get her back!"

It was really disgusting to see the behavior of her nephew's wife. Old Mrs. Xu saw that it was getting late and she had to hurry home, so she couldn't delay.

Fortunately, I told Mr. Xu to pick them up after buying the things.

At this moment, Xu's father knocked on the door and came in.

Old Mrs. Xu asked Xu's father to carry her sister to the car, and asked Haizi to take a lot of his mother's things.

When leaving, Haizi stuffed a lot of money into the hands of Old Lady Xu. His wife was so anxious that her eyes turned red. As soon as she opened her mouth, Haizi slapped her in the face. She could only cover her face and cry.

Father Xu still didn't know what was going on and could only serve as a background figure. When Haizi asked him to take better care of his mother, Old Lady Xu scolded him, "Go away! Teach your daughter-in-law a lesson. What a piece of shit! She's so heartless! Aren't you afraid that when she becomes a mother-in-law in the future, she'll be treated like this by her daughter-in-law?"

Haizi smiled bitterly and could only escort them out of the alley.

When they got outside, Old Mrs. Xu left cursing.

After leaving the alley, Xu Xiaoya explained to her father what had happened. Her father felt very sympathetic towards his aunt, but he still had a headache.

My aunt is in this car, how can I get the things she needs back?

He did buy some things, but those things didn't take up much space, and they would definitely fill up the place soon.

Old Mrs. Xu had no idea what Mr. Xu was worried about, and kept criticizing her sister.

The two sisters didn't care about the facial wounds at all, they just poked them however it hurt.

Both Xu's father and Xu Xiaoya were helpless. They had always known that Old Lady Xu had a bad temper and was harsh with her words, but they never knew that she would be so rude to her own sister.

Halfway through the journey, Old Mrs. Xu asked Father Xu to take them to the grocery store.

The former boss Huang has passed away, and the owner of the grocery store has changed, but it is still a grocery store, and it sells salt and sugar.

Old Mrs. Xu didn't dare to buy all of the other party's inventory, but just bought everything that was on display. After all, they were people from the mountains, so it was reasonable for them to buy things this way.

In addition to salt and sugar, Old Mrs. Xu also bought a lot of cotton.

Neither Xu's father nor Xu Xiaoya understood what she was doing. After all, Xu Xiaoya could trade these things, and it would be more cost-effective. Why did Old Lady Xu go through all this trouble?

But when they were almost at the town, Xu Xiaoya knew what was going on.

She asked Xu's father to carry her sister to a distant place to relieve herself, and during this time, she asked Xu Xiaoya to exchange all the cotton for salt and sugar, as well as some food.

Because they were all packed in sacks, you couldn't tell what had been changed inside.

Old Mrs. Xu went with her sister. When she came back and saw Xu Xiaoya nodding at her, she knew it was done.

It was completely dark when they arrived at the town. Old Mrs. Xu asked Father Xu to carry her sister to their house in the town to rest. The things on the ox cart had already been handed over to the person in charge of the base, who would count all the supplies.

Those revolutionaries were very poor and could not come up with any money at the time, but they tried their best to raise funds. It was only when Old Lady Xu asked them to write an IOU that the difficult fundraising ended.

Anyway, Old Mrs. Xu was relying on Xu Xiaoya for the things she got from the trade, so she didn't feel sorry for it.

He looked at the IOU in his hand and wanted to tear it up, but Xu Xiaoya took it away.

Just kidding, these things can be kept as heirlooms in the future. If something happens to the Xu family decades later, these IOUs can be used to prove their innocence.

Besides, it won't be damaged if it is placed in space, so why doesn't she keep it?

What Xu Xiaoya didn't expect was that a message popped up on the system asking her to shoot a video about those IOUs.

Thinking of the last video, Xu Xiaoya had a premonition.

She quickly shot a 15-second video, explained the historical context, and ended it.

But she had no idea that the people who saw the video were shaking with excitement after seeing the words on the IOU, as well as the signature and name on it.

Chen Zian couldn't believe his eyes. He rubbed his eyes and confirmed again and again that he did see familiar words. However, because he was too excited, he didn't dare to be 100% sure, so he called his son to find his grandfather's diary.

He checked the contents of one page of his diary over and over again.

On that page was an IOU, but it was a copy made by his grandfather because the original was never recovered.

His grandfather told him that if it weren't for those IOUs, they would definitely not have survived the most difficult years, and many comrades would have sacrificed their lives.

Unfortunately, because of the Anti-Japanese War, I never had the chance to see that kind-hearted aunt again.

Chen Zian's grandfather kept talking about this matter until his death. He always wanted to get back the IOU he wrote that year.

Many years later, Chen Zian actually saw this IOU in a video. The content on it was exactly the same as the IOU left by his grandfather, even the handwriting was the same.

This made Chen Zian certain that the IOU in the video was the original one written by his grandfather.

He kept leaving messages under the video, but unfortunately Xu Xiaoya couldn't see them.

Until he saw a transaction reply, he immediately agreed.

It was a transaction that required a large amount of sugar and salt, and the quantity was huge, but Chen Zian didn't hesitate at all and directly arranged for his son to purchase it.

Their Chen family did not join the military or politics like their grandfather. In his later years, the old man did not allow his grandsons to enter the system based on their status. Instead, he let them do business, mainly engaged in military supplies, because he was afraid that others would not be able to guarantee the quality of the military supplies.

Even based on the transaction amount, the money spent is just a drop in the bucket for their Chen family. But if they can get this IOU back and burn it for grandpa, it will be considered as fulfilling grandpa's wish.

The transaction was completed. Xu Xiaoya was so happy to see the large amount of sugar in front of her that she donated it all to her comrades in the base.

White sugar is a war reserve material and is very useful!
