Jiang Yan finished calculating the latest data and straightened his back.

After not getting up for a long time, his waist was already a little sore.

This is him, young and strong. If you look at the people around him, you can see that the older ones have already been beaten on the waist for a long time.

But no one complained.

Because we have to race against time.

"We don't have eight years, not even two years. We only have one computer, so there are no shortcuts. We can only use an abacus!"

Several times, Jiang Yan wanted to take out the computer in the space.

After all, I am so tired!

He thought silently in his heart that the other world was fake, it wouldn't hurt to change, and he wouldn't have to be so tired.

But he didn't do this. Secondly, it violated the plot. Most importantly, he always felt that it would insult everyone present.

So keep dialing the abacus. If you really want to do it, we’ll talk about it in the next scene.

Soon, the time came to zero.

Lu Guangda stood up first, clapped his hands and said:

"Everyone go back!"

Then the sound of the abacus stopped.

Then someone slowly stood up, but did not leave, but gave the data to the team leader.

Just like that, another half an hour passed before the work was completed.

Lu Guangda was the last to leave, and he was responsible for turning off the lights.

More than five hours later, it was 5:30 the next morning.

The sound of abacus was heard in the room again.

Jiang Yan stared at his slightly swollen eyes and continued to adjust the abacus.

The swelling is because I didn't sleep well last night.

This is tiring.

After all, this experience was his first time.

So my hands are tired, my waist is tired, and my brain is tired.

All the difficulties that "Intellectual A" had to adapt to, all broke out again for Jiang Yan last night.

The most uncomfortable thing is that when you close your eyes, it's all data.

And I always feel like there is something wrong in my calculations.

So I woke up many times in the middle of the night.

After recalling it for a while and confirming that it was correct, I fell asleep lightly.

That feeling, from Jiang Yan's own perspective, was really uncomfortable.

Fortunately, it's over in half a day.

"I just don't know if I will have abacus skills when I go back this time."

Jiang Yan joked to himself, and then plunged into the ocean of data.

...

Five hours later, it's lunch time.

His wife came again, and after delivering food to everyone, it was Jiang Yan's turn.

It was still an aluminum lunch box, with two big steamed buns accompanying the side dishes, but during the break, she stuffed Jiang Yan with an apple.

Jiang Yan broke it open and handed half of it back.

The wife took it with a smile and looked into each other's eyes, both of them knowing the friendship between them.

Love in this era is so simple.

Then, the crackling sound of abacus continued to drown out everything.

The new soldier standing guard outside said doubtfully:

"Company commander, what are they doing?"

The company commander said proudly with his hands behind his back:

"What to do? Make a revolution!"

When the little soldier heard this, the backs of the group of intellectuals suddenly seemed as high as a mountain...

.....

Three hours later.

Jiang Yan finally returns.

Different from the past, this return did not take a deep breath, but suddenly stood up with a start.

I haven’t finished calculating the data yet!

In the next second, he finally recovered.

Looking at the prop abacus in my hand, I felt empty.

Although he believed that this time traveling was the most tiring one for him.

But now that he has left, he feels a strong sense of nostalgia.

What's the matter with the reluctance?

At this time, Teng Rujun's voice interrupted Jiang Yan's thinking:

"Xiao Jiang, do you know how to use an abacus?"

Jiang Yan pursed his lips and said, "...you should know a little bit."
