Manbao didn't know, and Bai Shanbao and Bai Erlang knew even less.
Bai Erlang didn't even glance at the farming book, asking directly, "Is the person who wrote this book very good at farming?"
"I'm not sure about that, but they must be very good at studying." Otherwise, they wouldn't have been admitted to a graduate program.
Bai Shanbao and Bai Erlang had no objections to this point, reasoning that if one wasn't adept at studying, they wouldn't be able to write a book either.
While writing, Bai Shanbao realized that the problems were increasing and he could only turn back and read the farming book carefully. Sighing, it seemed that making plans was necessary; not taking studying seriously was unacceptable.
The three friends discussed together, but although they had read a lot, they had little experience in farming, and often had to stop halfway through their planning.
In the end, Manbao said, "I need to go back and ask my elder brother."
