In Lin Han's consciousness, there is a "holographic projection map" covering 30,000 square kilometers in the northern part of Jiangsu and Zhejiang Province, with hundreds of collection points, large and small, distributed in the gathering places of wild bullfrogs in various places. [Latest chapter reading.]

As soon as ten o'clock arrived, countless wild bullfrogs in this range rushed to the nearest collection point as if they had received an inviolable summoning order.

As a result, in the entire northern part of Jiangsu and Zhejiang provinces, with hundreds of collection points as the center, countless bullfrogs poured in like a tide and gathered rapidly.

In Lin Han's perception, these hundreds were like magnets, frantically attracting bullfrogs in various nearby areas

For a while, there was the sound of frogs near the various collection points.

"Goo-quack-quack-"

"Goo-quack-"

The grass is full of rustling sounds, and the nearby river is rippling from time to time.

Accompanied by the sound of frogs, it is not difficult to find a large wave of bullfrogs in the night, sometimes jumping out of the water, sometimes jumping over the grass.

On the stone bridge, two members of the Agricultural Bureau, one fat and one thin, looked at the wild bullfrogs that were rushing towards the bridge pier as if they were marching, their eyes widened, and their faces were full of disbelief.

"It's really here!"

"I'm rubbing, so many bullfrogs!"

Right under the noses of the two of them, groups of bullfrogs gathered, quickly gathered near the bridge pier, and the frog shadows jumped.

"Gollum—"

After a while, the bullfrogs that arrived gradually became scarce, and the frog voice became a little low.

Around the piers, a group of fat wild bullfrogs were already densely packed, except for breathing or occasionally calling twice, they were all motionless, almost as if they were in a steady.

Looking at such a scene, the two of them looked at each other.

"So go down and pick up bullfrogs?"

"Let's go down then. ”

The two immediately got off the stone bridge, put on gloves, and ran to the periphery of the bullfrog circle with sacks.

The fat man walked cautiously, as if he was afraid that the bullfrog would escape.

Then he crouched down and reached out to grab a fat bullfrog.

"Hey, you really don't resist!"

The fat man poked the bullfrog with his finger in surprise, and the bullfrog only made a symbolic croak, shook its legs, and then stopped moving.

The thin man next to him was already busy, grabbed two or three bullfrogs in one hand, and threw them directly into the sack.

"Catch it, so many bullfrogs. ”

It didn't take long for the thin man to fill a half-sack of bullfrogs. Then he picked up the sack and lifted it, causing the bullfrog to scream.

"Goo-quack-"

The thin man looked at the half of the stay in his hand, and then looked at the remaining bullfrogs nearby, and couldn't help frowning slightly.

The place that the two of them are responsible for was originally just a small collection point, and the number of bullfrogs is not too much.

But at the moment, two sacks may not be usable.

"I remember that these bullfrogs collected by our Agricultural Bureau are all near polluted water bodies, right?"

The fat man nodded while picking up the bullfrog and said, "It seems so." I heard that it is intended to be used as organic waste to make fertilizer and generate electricity. ”

"In that case, don't worry about life or death. ”

The thin man immediately turned the mouth of the sack to the side, and then used both hands together to press the half bag of bullfrogs.

"Quack!

"Quack!

After some compression, many bullfrogs in the sack died on the spot.

Seeing this, the fat man couldn't help grinning: "You are so perverted." ”

The thin man lifted the sack: "If you don't press the space, two sacks may not be enough." When the car from the assembly point comes to collect it, do you want to throw the bullfrog directly into the car?"

There are more than a dozen bullfrog collection points in the vicinity, and the largest collection point in the center is used as a meeting point for everyone, with two trucks on standby for subsequent shipments.

At midnight, trucks at the meeting point will start to travel between the meeting points, loading all the bullfrogs collected by the crowd into the trucks and transporting them to the designated location for processing.

The two of them were busy for a long time, and the bullfrogs near the bridge pier were cleaned up and put into sacks.

"It's finally finished. ”

The two wiped their sweat and sat on the stone bridge waiting for the car.

"Fatty, aren't you a student of biology? What kind of method do you say Vientiane used to gather all these bullfrogs near the piers?" asked the thin man.

"You still ask me, aren't you also a student of biology? ”

The thin man smiled: "I am not good at learning"

The fat man said, "I'm wondering too." Generally speaking, to attract a certain animal to gather on its own, that is, to put some special chemicals in a designated place. If it's colorless and odorless, it's nothing if we don't notice it. ”

"But I wonder, if there are any special chemicals around here, why doesn't it take effect until ten o'clock at night?"

The thin man thought for a moment, "Maybe, this thing is timed?"

"How do you time it?"

"I don't know this, that's why I asked you. ”

“”

After waiting for a while, the two trucks finally drove up. One of the cars was already full of sacks, and it looked bulging.

Another truck was packed with half a truck of sacks of bullfrogs, as well as other agricultural bureau staff responsible for the collection.

"Let's put the bullfrog in the car. The driver poked his head out and said.

"The sacks were not enough, and many bullfrogs were squeezed to death. It must be sent to steaming and inactivation as soon as possible, otherwise it will rot. ”

After a busy night, the wild bullfrogs in northern Jiangsu and Zhejiang provinces were all collected.

The staff of the Agricultural Bureau are okay, anyway, they pollute the bullfrogs, and they don't have to worry about life or death, they stuff them into the sack and get it done in one trip.

The people of the breeding association are troublesome.

After all, the bullfrogs they caught were used to prepare for sale, and in order to ensure survival, they had to run back and forth two or three times, and they were busy until dawn.

The contaminated bullfrogs collected by the Agricultural Bureau were all cooked at high temperature the next day, sterilized and inactivated.

The treated bullfrog carcasses were then tested for heavy metals in samples taken according to the area.

After testing, it turned out to be. These polluted wild bullfrogs have a lot of heavy metal content exceeding the standard, not only can they not be eaten, but they can only be used as biomass dyes to contribute to electricity.

Considering that the vast majority of biomass power plants need to be improved, the treatment is not thorough enough, and the heavy metal components cannot be effectively utilized.

So Lin Han finally decided to transport the bullfrog carcasses to the Vientiane Garbage Disposal Company in Yunzhou City after embalming.

When the company's biomass power plant is in operation, these high-quality power generation materials with high organic content will be sent to the power plant to generate electricity.

Although it is a loss of money when you count the freight, it is obviously nothing compared to the hundreds of millions of dollars in fees for the management of invasive species.
