After lunch, it's time to head to school.

Gu Yunyang asked, "Xiangrong, if you want to stay at home for a few more days, you can go a few days later."

But Chen Xiangrong still wanted to stay with Gu Yunyang and spend a few more days together.

In those days, transportation was very slow.

It takes a month for letters to be exchanged.

Sometimes, it might take a whole month to make the round trip.

Love in this era is pure; a letter can convey a sentiment.

The feelings in this era are very sincere and resilient. Even if the couple is not in the same place, they can still maintain their relationship.

But since they could spend time together, Chen Xiangrong also wanted to spend more time with Gu Yunyang.

Chen Xiangrong joked, "I stayed at home for a long time. Except for the first two or three days when my parents really liked me, after that they complained that I stayed at home for too long."

Chen Feihong and his wife remained silent, watching the two little ones with smiles.

They understood their daughter's thoughts, and what Gu Yunyang was about to do was actually to protect them.

How could they possibly make things difficult for Gu Yunyang?

The couple saw their two little ones off and followed the bus to Guangzhou for a long time until they boarded it.

Until it's completely out of sight.

Madam Chen sighed, "Sometimes it feels like she just came back yesterday. But in the blink of an eye, she's leaving."

She longed to keep her daughter by her side.

Unfortunately, she couldn't be that selfish.

Gu Yunyang joined the professor's team partly because he wanted to realize his own value.

On the other hand, it was also to protect his father-in-law and mother-in-law.

Madam Chen knew this, so she couldn't say anything.

Chen Feihong held his wife's hand and comforted her, "Didn't Xiangrong say that after she graduates, she will be assigned to work in the commune? Then she can live at home. We'll be the same as before."

Madam Chen then nodded.

After Gu Yunyang got into the car, he quickly took out an orange and handed it to Chen Xiangrong.

Chen Xiangrong was a little carsick, especially in noisy environments and places with a strong smell of gasoline.

Seeing how detailed Gu Yunyang's preparations were, including items like dried tangerine peel in his bag to treat motion sickness, she was very pleased.

Chen Xiangrong felt a warm feeling in her heart.

We traveled back to Guangzhou in silence.

The two immediately returned to school.

In the days that followed, Gu Yunyang began to prepare in a methodical and intense manner.

He went to the lab first, met with the professor, and discussed it further.

This time, they need to prepare a lot of things in advance for their experiment in the Gobi Desert.

This isn't the first time it's happened.

But every time the professor went there, he felt that "the conditions in the Gobi Desert are very basic. Every time we went there, we felt that no matter how much we brought, it would not be enough."

Gu Yunyang nodded; he himself wasn't afraid.

He has plenty of stuff in his base.

However, this time, what he brought up was not a personal matter.

Gu Yunyang said, "Professor, as we all know, the most difficult part of desert transformation is actually sand fixation and water retention."

The professor nodded: "You've hit the nail on the head. In fact, the desert needs drought-resistant plants, but there are quite a few drought-resistant plants."

However, if it cannot retain water, it cannot survive, no matter how drought-resistant it is.
