"You don't mean them when you say guests, do you?" Lena immediately understood what Gangu Yu meant, and asked with a glaring glare as she pointed to the demon locust captives that had been captured alive.

"It's not them, do you want to try it yourself?" Gan Guyu chuckled, and then instructed, "Take the demon locust to the wheat field and loosen it, let's see the effect." ”

Lena looked at the Gao brothers, who nodded, and forced the pungent smell of pesticides to bring the demon locusts closer to the wheat field that had been sprayed with pesticides. Just as Gao Da was about to untie the trapped beast rope, Gan Guyu suddenly said again: "Gao Da, put five ordinary demon locusts first, and one each of the alpha type and beta type first." ”

"Got it, Young Master Gu Yu. The three brothers agreed in unison, and then released the first captives.

The alpha-type and beta-type demon locusts that had regained their freedom glanced at the Gao brothers, as if they knew that they were invincible, so they gave up the plan to fight back and take revenge, and then they rose directly into the sky, without looking at the wheat field in front of them, and were ready to escape.

Seeing this, Gangu Yu's face changed, and his brows couldn't help frowning. However, before he could speak, the Gao brothers consciously used spiritual magic. The two demon locusts were mentally disturbed, and their eyes finally fell on the wheat seedlings, and without saying a word, they turned around and fell into the wheat field to eat.

Seeing this scene, Gangu Yu's face was slightly pale. It seems that just now it was just the natural reaction of the demonic beast to seek advantage and avoid harm, and after escaping the restraint, it wanted to escape as soon as possible. However, as long as they saw the food, the fear that the locust had felt before was dispelled a lot.

The five ordinary locusts were slightly different. One of them, after being loosened, pounced on the wheat field without saying a word, as if there was nothing else in his eyes. But the other four ordinary demon locusts only cared about escaping, no matter how the Gao brothers induced them, they always regarded the wheat field as nothing.

"Could it be that these four demon locusts have a keen sense of smell? Don't you want to eat the wheat seedlings with this unpleasant smell?" Pei Pei guessed.

"It doesn't make sense!" Gan Guyu scratched the back of his head, his eyes also revealing puzzlement, "It's also an ordinary demon locust, how can some people be willing to eat this wheat seedling, and some are unwilling-uh, I think I understand why." ”

Pei Pei was surprised when he heard this. He looked at him and asked, "Why?"

Gangu Yu smiled bitterly and didn't speak, raised his hand and fired four water guns in succession, shooting the four demon locusts that had always wanted to escape to the ground, and then immediately cut off their heads and took a look, and immediately had a little confidence in his guess in his heart.

These ordinary demon locusts have not yet condensed magic crystals, and they are not really magical beasts in the strict sense, and locusts that are not considered magical beasts are actually a kind of insect infestation. And the wheat seeds that Ganguyu took out just now were the seeds that he subconsciously completed the optimization of immunity to pests and diseases. Such wheat seedlings. Ordinary demon locusts that are not yet Warcraft will naturally just turn a blind eye.

To find out if this is the case, we need only look again to see if the locust that pounced on the wheat field has a magic crystal. And in just a few moments, the ordinary demon locust had stopped eating, lying on the ground shaking its legs incessantly. After a while, it stopped moving.

Qiu Yi and others not far away couldn't help but be a little surprised when they saw this. Is there really a poisonous immortal crop in this world, but can it poison the medicine of the demon locust? And Gan Guyu directly cut off the head of this ordinary demon locust, and one of the small first-order wind system magic crystals was exposed.

It's really a big oolong! Gan Guyu shook his head and laughed at himself twice. Only then did he look at the two high-level demon locusts. At this time, the Alpha and Beta Demon Locusts also stopped eating the wheat seedlings, but not before. These two locusts alone devoured a small field of wheat.

At this time, they constantly tried to fly, but fell to the ground again and again. After struggling for a long time, they are considered dead.

Ignoring the pungent smell of pesticides, everyone gathered around in amazement, looking at the corpses of the demon locusts on the ground and marveling inexplicably. Qiu Yi was the first to ask, "Xiao Gu Yu." How did you configure this potion, how much did it cost, and could it be widely promoted?"

Before Gan Guyu could speak, he heard Lina on the side exclaim, "Dabao, what's wrong with you, you're not feeling well?"

When everyone heard the call, they immediately turned their heads to look. I saw the tall brows furrowed deeply, and he stroked his chest with one hand. Said sullenly: "Well, I'm a little dizzy, my chest is a little stuffy, and I want to vomit ......."

Gangu Yu was shocked: "Pesticide poisoning? Quickly, everyone retreats first and stays away from here!"

Seeing this, everyone dared to stay longer, and hurriedly covered their mouths and noses and flew back, until they could barely smell the smell of pesticides. Gangu Yu walked in front of Gao Da in a few steps, observed his skin and pupils, and then breathed a sigh of relief: "It's okay, it's just a slight poisoning, I think it should be that Gao Da was too close to the wheat field just now and got some medicine." ”

"That's right. The second year of high school was a little embarrassed, and at the same time a little anxious, "Just now the eldest brother was curious and touched a wheat seedling. ”

Only then did everyone suddenly realize. However, only a small amount of contact can be poisoned, and the poison of Gangu Yu's potion is really strong enough. And such a drug does not poison the wheat seedlings, is it only effective for living creatures such as humans and monsters?

How could Gangu Yu pay attention to everyone's speculation at this time, and directly took out a holy light washing scroll and smashed it at Gao Da. After a golden light, Gao Da breathed a sigh of relief and smiled: "Huh, I'm fine, thank you Young Master Gu Yu." ”

Only then did Gangu Yu nod reassuringly, and after a moment of silence, he smiled bitterly at Munster and Qiuyi: "Mentor Munster, Elder Qiuyi, it seems that my medicine can't be promoted. ”

"Why? Is it because it is too toxic? How about increasing the dilution ratio?" asked Qiuyi.

Gangu Yu shook his head: "If it's just because it's too toxic, just let the poison applicator strictly isolate it from this liquid." But in fact, the effect of this medicine on people seems to be much stronger than that on high-level demon locusts. Gao Da, as a fourth-order magician, couldn't resist this poison, and the two alpha-type and beta-type just now had eaten so many wheat seedlings before they were poisoned to death, according to that ratio, the wheat seedlings in a field would poison a hundred or so high-level demon locusts at most. Our wheat seeds are not blown by the wind, it is too expensive and inefficient!"

Qiu Yi was silent for a long time when she heard this, and finally had to nod a little frustratedly.

In fact, Ganguyu found more than that. Phosphine is a low-residue pesticide that decomposes by photo, so it is mostly used at night or in the evening, and Ganguyu is intended to use it to spray the land on a large scale, using the effect of phosphine in the soil for a long time to kill the larvae of locusts.

However, in this way, pesticide residues will inevitably add a little more toxicity to the barren land of the barren and barren continent. After the drought, when there is a little more groundwater, this organophosphorus pesticide can also cause environmental problems such as eutrophication of water bodies. These problems are not a problem for the **** people who have long been adapted, but now it seems that the people on the salty continent have almost no resistance to them.

It is precisely because of this that the promotion of phosphine cannot be carried out. If a fourth-order magician is like this, once these pesticides flow into the hands of ordinary farmers, if they are not applied according to the instructions, how many incidents will be caused? Maybe the demon locusts did not poison much, but ordinary people poured a large piece. (To be continued.) )
