Fu Yuanzhi not only helps catch insects in Xiao Zheng's field every day, but also stays in other people's wheat fields, and this stay is half a day.

It's just that Fu Yuanzhi hasn't been able to find anything wrong from it.

As the sun sets over the peaks, the afterglow casts a golden shadow over the village.

Fu Yuanzhi poured the heart-digging worm he caught into the chicken pen of the master's house.

Fu Yuanzhi finished this series and walked unhurriedly in the direction of Li Zheng's house.

When Fu Yuan crossed a small stream on the road, a group of half-grown children were swimming in it and having water fights.

When Fu Yuanzhi walked under a big tree on the shore, he saw a child dressed in patched cloth, about seven or eight years old, with a small stone under his buttocks, and saw him looking up at his companions in the stream from time to time, and poking back and forth on the ground with the small stick in his hand from time to time.

Fu Yuanzhi knew this child, the other party was a child of the Xiao Zheng family, he stepped forward, squatted down and said, "Niu Wa, why don't you go with them?" ”

Niu Wa looked at the adult opposite her whose father had been praising her, first got up very politely and called Fu Yuanzhi respectfully, and then said, "Daddy won't let me play in the water." ”

Fu Yuanzhi touched Niu Wa's head, and then asked, "What did you poke with this branch just now?" ”

Hearing this, Niu Wa pulled the loess that had just been covered open, and a caterpillar appeared in the pit.

Fu Yuanzhi just wanted to say something, but he suddenly realized that this caterpillar was not quite right.

Fu Yuanzhi picked it up, the caterpillar no longer had that feeling of flesh, it was like stepping from the age of youth to the age of aging to stepping into the coffin immediately, and under it was a yellow cocoon, and the whole seemed to be the caterpillar holding the yellow cocoon tightly.

And the whole cocoon has been punctured by the cow baby, revealing small white cocoons inside.

It was the first time Fu Yuanzhi had seen a caterpillar of this appearance, and he was curious for a moment: "Where did you catch this from?" ”

Niu Wa pointed to the wheat field not far away.

……

Fu Yuanzhi took this unique caterpillar away, and he was carefully observing it all the way, although he didn't know why, but maybe because he didn't get anything for half a month, he was surprised by this slightly different place.

Fu Yuanzhi went home and put it in a small wooden box.

He suddenly smiled.

He was so mad that he brought it back in a haunt.

Fu Yuanzhi sighed and didn't send it back.

It's just that when he saw a nematode coming out of the mantis's belly on the road four days later, Fu Yuanzhi suddenly had a flash of inspiration.

Words that he had heard before popped into his head.

Parasitism.

Madame once said that some insects can parasitize other insects.

So, can heart-digging worms also parasitize?

The parasitic worm will die because of the birth of the host, so the heart-digging worm can easily solve it without their intervention!

Moreover, the planting area of Changliu Village is so large, and the number of heart-digging insects is not as large as that of Dasi Nongsi, can he boldly guess that there may be worms that parasitic heart-digging worms everywhere except Xiao Zheng?

Fu Yuanzhi's original footsteps of wanting to go back stopped instantly, he directly reversed the direction, he urgently needed to do an experiment now!

After Fu Yuanzhi ran out for a distance, he felt inconvenient and ran back again, and he directly asked Li Zheng to help.

The two hangs of money prepared by Fu Yuanzhi were gone in one day.

The reason is that Fu Yuanzhi asked Li Zheng to help tell the villagers to sell all the heart-digging worms they caught in the wheat field to Fu Yuanzhi.

The people in the village of Changliu Village have never seen the rare thing that the nobles want to buy bugs, and everyone can't help but have doubts, but this is said by the inside, and everyone has the attitude of giving it a try.

This kind of good thing swept through the entire Changliu Village in an instant, and everyone threw themselves into catching insects.

Fortunately, Fu Yuanzhi made a prerequisite, it must be a heart-digging worm in his own field, and if it is pretended to be from other places, it can only be invalidated.

Fu Yuanzhi's identity is still a deterrent, and no one dares to be careful.

Fu Yuanzhi's purpose was achieved, there was a lot of strength in numbers, Fu Yuanzhi separated the wooden boxes that had been packed one by one according to the names of the characters, for example, those sent by Uncle Gao's family were labeled "Uncle Gao's family, thirty-five".

Of course, there are contrasts, and the comparison is the heart-digging worm in Xiao Zhengdi.

If it is proved that the heart-digging worms in the wheat fields other than Xiao Zheng's family are parasitized, which causes the long-staying village of the panwheat to not be greatly affected, they can start from this aspect!

Since Fu Yuanzhi was going to carry out this experiment, he has never been out of Lizheng's house again, except for coming out to get the cut wild vegetables or carat leaves, he has been at home behind closed doors at other times, and has been observing their changes.

Although it is very slim, Fu Yuanzhi still has to try again, knowing the natural enemy of the heart-digging worm, the panwheat in the capital will be able to grow as smoothly as Changliu Village!

Fu Yuanzhi didn't know what form the capital should be in today's place, but in order for Song Yi to be able to resist for a longer time, Fu Yuanzhi felt that he still had to write down the breakthrough point he had found.

Now that he has found a solution, Song Yi's side will not always be at a disadvantage.

Fu Yuanzhi's letter was indeed timely, and with a breakthrough point, Song Yi's confidence increased greatly.

Of course, he didn't think of a new way.

Now, he has some ideas, too.

If people can be poisoned by medicine, why can't insects?

Song Yi had this idea, he was running towards the medical hall every day, but the medical hall was a doctor, and Song Yi had to return disappointed.

If you can poison people, you can definitely poison insects, but if you poison insects like this, how can you eat food?

Therefore, Song Yi's move is destined to get no results in the medical hall.

However, there are many roads that can't be taken by one road, and the difference is just a few detours.

Since this heart-digging insect harms wheat, millet, sorghum, beans, etc., then list them one by one and eliminate them one by one.

Why does the heart-digging worm get these food hazards, but other varieties are not harmful, is there something that can drive it away?

Song Yi has figured this out, and the other joints can also figure it out when they think about it.

This time, not only Fu Yuanzhi was doing experiments, but Song Yi was also doing comparative experiments in hard investigation and research.

What green onion solution, leek solution, bitter gourd leaf solution, garlic solution, etc., as long as it is a heartworm that does not eat, he has tried it all.

Don't kill it, smoke it away!

It's just that some of the red spiders in the wheat have been taken away by him, and some of the heart-digging worms are still strong.

Song Yi thought it might be because they were in the ears of the wheat, and there was little solution to pour it, so they couldn't smoke it at all.

Song Yi guessed this possibility and directly prepared to use irrigation, because of the large amount of work, Song Yi could only select part of the experimental site to carry out, and after ensuring that nothing went wrong, he was going to the next step.
