Seeing Lin Weiguo so upset, a trace of annoyance flashed in her almond eyes. She was really talking about something that was not related to the topic.

I shouldn't have said this earlier.

However, she seemed to remember reading in history books that fertilizers that could increase production would be produced in the future.

There is also hybrid rice that has doubled its yield per mu.

If their team had these, all difficulties would be solved.

Even if it doesn’t work, we can try to build ecological farms in the future.

Lin Ran silently kept this in mind and planned to look for relevant books in the space to study them when she had time.

The atmosphere at the scene was a little dull because of this topic.

Shi Yan glanced at Lin Ran who was lost in thought, and Lin Weiguo who was frowning, and subconsciously helped them think of countermeasures.

He came from a wealthy family when he was a child, and his study had a large collection of books, so his knowledge range was also very broad.

His mind works quickly when he thinks about problems.

Since it is impossible to grow crops in the mountains, what about growing other plants?

Shi Yan thought and said so.

But Lin Weiguo shook his head.

"I know the educated youths were kind enough to give us advice, but the farmers in our brigade have been growing crops all their lives and don't know how to grow anything else."

"And even if we planted it, there's nowhere to exchange it for food. Food is the most precious thing right now."

"If you grow your own food, you can at least get some food. Even if it doesn't fill your stomach, it's still food. If you grow other things, not only will you not earn any food, you might even end up losing it."

No matter how much Shi Yan knows, he is not a country boy after all, so his perspective on things is naturally not that comprehensive.

However, after Lin Weiguo's guidance, he followed Lin Weiguo's train of thought and came up with another idea.
