The couple went back home, satisfied.
That same evening, they sent 20 bags of earthworm compost to Qi Lin's grandfather.
Qi Lin sighed, "The comparison test doesn't need that much, two bags are enough."
Yunyun's husband is an honest man. Knowing they had put in significant effort in developing this technique, he simply grinned sheepishly:
"This isn't worth much, what's so valuable about earthworm poop? We'll bring more next time."
As soon as he finished speaking, he unloaded the sack, turned, and rode off on a tricycle with his wife.
Meanwhile, Qi Lin's grandfather stared at the large bag of earthworm compost on the ground, looking puzzled:
"Didn't you say not to use chemical fertilizers in the field?"
Qi Lin smiled wryly, "You can use this; it's organic fertilizer."
...
There's no denying that an honest person has advantages in work.
Qi Lin had planned out the instructions, and he followed them to the letter.
