Jiang Xuan stood in the middle of the vegetable field, and the scene of insects eating crops was full of scenes, and there were various "rustling" sounds in his ears.

If he couldn't think of a way, all this large crop would be eaten up by insects. Even if they planted tubers, the autumn harvest yield would be outrageously low.

"Chief, don't be anxious, think about it carefully. Since the witch in the dream has taught you how to plant, she must have taught you how to solve this situation."

When Jiang Xuan was upset, a pair of warm hands were placed on his shoulders, and the gentle voice relieved his nervous mood.

That's the arrival of Red Peony.

Jiang Xuan nodded, took a deep breath, and began to recall the various experiences of controlling insect scourges in his previous life.

First of all, it is artificial culling. This method is the simplest, but the efficiency is also the lowest. With the help of the Vine Tribe, the crops were already gone before they could kill these pests.

The second is drug treatment, which is the fastest and most effective method of governance, but the Vine Tribe does not have insecticide medicine, so this method simply doesn't work.

Then there is the legendary duck raising and insect eating.

The Vine Tribe currently has no other breeding industry except fish farming, and there is not even a duck.

This method also doesn't work.

This is not OK, that is not OK. What should I do?

Everyone was waiting for the leader to come up with an idea to deal with these pests, but Jiang Xuan had no choice but to do it. This feeling was so uncomfortable.

"You guys catch insects first, I'll think of a solution."

After Jiang Xuan left a sentence, he walked away depressedly, hoping that after walking and looking, he could bring new ideas to himself.

Gan Song and others looked at each other, and anyone could see that the leader seemed to have no choice.

Gan Song gritted his teeth and said, "Catch the insect!"

Then, he picked up a bamboo tube, squatted on the ground and quickly grabbed the insects. He would pinch each insect and throw it into the bamboo tube so that he could take it back and eat it.

The tourists also took action again, including Chishao and others, and joined the ranks of catching insects.

While catching insects, Chishao looked at Jiang Xuan from time to time, and the worried expression on her face was very obvious.

These arable land were opened up bit by bit by bit, and Chishao knew very well how much effort Jiang Xuan had put into farming.

If the insect plague cannot be solved, no matter how many fields are cultivated or how many crops are planted, it will be useless and will only become food for insects.

They are very good at dealing with wild beasts, but tribes have no experience in dealing with such large-scale insect scourges.

Red peony can only be anxious and can't help.

Jiang Xuan walked slowly in the field, and his mind kept recalling various methods of controlling insect plagues, but he himself had not experienced insect plagues himself and lacked experience in this area.

Do crops that have been planted with great effort really have no harvest?

Jiang Xuan was very unwilling to give up. As he walked, he walked to the edge of the pond.

"Swoosh!"

In the water beside the pond, a big frog suddenly opened its mouth, and a tongue ejected out like lightning, stuck a flying insect out of the air, and then slowly swallowed it into its belly.

Jiang Xuan's eyes lit up. It would be great if there were a large number of frogs, they could put them in the fields, as they could eat a large number of insects.

Unfortunately, it is obviously unrealistic to catch frogs temporarily. You can only rely on nearby frogs to enter the fields to prey on insects.

Jiang Xuan's eyes dimmed again, and it was a drop in the bucket to rely on such a few frogs nearby to eat insects.

Jiang Xuan felt a split headache and walked back into the bamboo house without realizing it.

He sat by the fire pit, looking at the beating flames, and suddenly a flash of inspiration flashed in his mind.

"Firelight, the phototaxis of insects!"

As the saying goes, one thought can be understood, and a hundred thoughts can be understood. When Jiang Xuan saw the fire, he naturally thought about how to deal with those damn pests.

Most of the pests in the fields of Vine Tribe are flying insects with wings, flying from other places.

Because of this, when they suddenly appear, they cause serious damage to the crops in the ground.

Because the Vine Tribe was unprepared, it was never expected that a large number of insects would suddenly invade.

These winged flying insects are huge in number and reproduce very quickly, and have extremely strong destructive power to crops, which is very terrifying.

But they are not without weaknesses either.

Their weakness is that they are phototaxis at night, like most flying insects.

Every night, it is when they are most active and the most destructive.

They rely on moonlight and faint starlight to determine the direction of their flight.

At this time, if a large bonfire appears, it will disrupt their flight direction and finally plunge into the fire and burn to ashes.

Of course, in theory, this is the case. Whether these pests will rush to the bonfire at night will only be known after trying.

With the mentality of being a dead horse as a living horse, Jiang Xuan immediately walked out of the bamboo house and came to the field, asking the three tourists to stop catching insects and were responsible for picking up firewood. Then he piled up in places where there were no crops in the field and piled up into many firewood piles.

Next, we are waiting for the night to come.

Jiang Xuan and everyone were trying hard to catch insects, while anxiously waiting for the night to come.

Time is like flowing water, the sun rises and sets, and the day quickly turns into night.

When night fell, Jiang Xuan lit a torch from the bamboo house, then walked into the fields, igniting the piles of firewood one by one.

"Crack crackle..."

The dry firewood soon started to burn, making a bursting sound, piles of bonfires ignited, and the flames illuminated the night.

The flying insects flying around in the plowing land and eating crops suddenly became at a loss in the face of the sudden appearance of strong light sources.

They flew around randomly, and then flew towards the fire in a spiral trajectory.

"Bang!"

The first bug flew towards the bonfire, and after being burned, it fell into the fire, and was burned to burst.

This bug is just the beginning.

Soon, countless flying insects rushed over like piles of bonfires, burned to death by the burning flames and burst.

"good!"

The tourists who had been waiting around cheered, and Gan Song's face turned red even more excited.

Jiang Xuan stood beside a bonfire and watched the insects fall one by one, and finally breathed a sigh of relief in his heart.

This method is effective, especially when dealing with these flying insects, the effect is very significant.

As long as these flying insects are burned to death, the remaining reptile insects are not so destructive, and the crops of the vine tribe can be preserved.

That night, countless insects were burned to death, and the smell of burnt spread throughout the open land, making countless beasts dare not approach.

The fire burned all night until it was almost dawn that Jiang Xuan and others returned to the bamboo house to sleep.

The same is true for those tourists. They need to add dry firewood or dry bamboo to the bonfire frequently to keep the bonfire burning.

It was not until dawn that the bonfire gradually went out and everyone could go back and rest.

There is only one exception, that is Gansong.

He watched the last bonfire go out, and picked up a roasted bug from beside the bonfire and put it in his mouth.

"Crack..."

The bug was roasted very crispy. Garcino chewed the bug a few times and swallowed it.

He walked slowly in the fields and carefully observed the crops. After finding that the number of insects was too small, he finally felt relieved.

"It's great. If you burn a few more times, you should burn all these insects to death. The things we planted can continue to grow."

Gan Song stroked a round potato seedling with broken leaves, and a gratified smile appeared on his face.
