In addition to these two people, there are also three employees of Vientiane Security Company, who are standing guard near with guns, and the scene is very serious.

After all, the United States is the world's largest economy, and of course Vientiane has some layout, such as Vientiane Security Company, which has set up branches in Michigan, Texas and other places, and has a certain number of guns.

The two of them held the foam box, and after walking to the water's edge, they carefully opened the box.

The foam box was so thick and tight that it took a lot of effort to open, and when it was opened, even if there was white gas, it was smoky and cold.

Amazing sight, everyone nearby couldn't help but look at it a few times and talk in a low voice.

The two security guards turned a blind eye to the white gas in front of them, and directly carried the side of the foam box and poured the water into the lake.

What is in this box is, of course, the nitrogen ice container produced by Vientiane.

After all, it was a show, so there were not many of them, and each box of a dozen fist-sized nitrogen ice containers fell into the water in the thick white fog.

The melting point of nitrogen is -210 degrees Celsius and the boiling point is -195 degrees Celsius, so in the room temperature environment, nitrogen ice is melting, boiling and sublimating all the time to become colorless and odorless chemically stable nitrogen, and at the same time take away a lot of heat.

The surrounding temperature plummets, the water mist condenses, and it is naturally full of white gas, which looks like a fairyland scene in the old version of the "Journey to the West" TV series.

In fact, it is true, the fluttering fairy fog in "Journey to the West" is not created by dry ice.

Moreover, the power of nitrogen ice is somehow higher than that of dry ice, and the scene is even more spectacular.

When the nitrogen ice enters the water, even though the white fog is full and rolls into the sky, the water surface with a sudden drop in temperature even condenses a small layer of ice.

A few grass carp in the vicinity were frozen into dogs in an instant, dead and wounded, and fled to other places in a panic, trying to survive.

It's just that they don't have that chance.

Not long after the nitrogen ice entered the water, Lin Han sat in the car, closed his eyes and began to obliterate the Asian carp in Yili Lake in patches.

Through the manipulation of intermediate life rights at the cellular level, he was able to easily destroy the central nervous system of living organisms, quickly inflicting devastating blows on these invasive species.

Soon, starting from the nearby waters, the Asian carp, which had just been extremely happy, disappeared in a blink of an eye, and was no longer silent.

At the water's edge, you can see patches of dead fish, rippling with the waves......

In a small forest not far away, two young Americans are holding cameras and taking pictures while observing the movement of Vientiane company personnel at the water's edge.

"I wonder what's in that foam box?" said the blond youth.

Beside him, about an Indian, black-haired and bespectacled, he also said, "Indeed, the scene just now is so amazing, the clouds and mist are soaring into the sky." ”

"It's a pity that these security guards are too close, and I don't know if we can get some useful information......" the blond young man sighed, "I've heard that the CIA didn't get any benefit from Vientiane." ”

The two security guards snapped the foam box to the surface of the water and patted it as if it were about to be shaken clean.

After pouring the nitrogen ice, they carried the foam box, walked straight into a garbage can not far away, threw it in very casually, and then left without looking back.

Looking at the scene in front of them, the two young men were stunned and looked at each other.

"Throwing it in the trash?"

"What do they mean by this, aren't they afraid that someone else will find something out of the box?"

“…… I think we should bring those two boxes. After a pause, the black-haired youth continued, "If they're careless, this might be our only chance." ”

"I think so too...... Wait a little longer, it shouldn't be long before they're gone. The blonde youth also seemed a little excited.

Sure enough, it didn't take long for everyone here in Vientiane to finish work one after another, return to the car, and leave here.

When they left, the two young Americans quickly came out of the woods, ran to the garbage can, and hurried away with two foam boxes.

……

For the next period of time, Lin Han used the same routine, and after throwing the nitrogen ice, he used his ability to quickly kill the Asian carp.

The coverage capacity of life authority is more than 30,000 square kilometers, which is extremely vast, larger than the entire Lake Yili, and can achieve full coverage by walking a little way.

I didn't throw much nitrogen ice, after all, this thing was just something to make a show and bluff for the American personnel who were secretly observing. Moreover, the temperature of nitrogen ice itself is extremely low, so it is not convenient to store and transport.

Therefore, in the eyes of the US side, the 27,000-square-kilometer Lake of Erie, Vientiane, is just a few boxes of unknown substances mysteriously thrown away.

This substance can produce a thick white mist, and the scene is so amazing that it is impossible to see the specific face at all, and even whether it is solid or liquid is uncertain.

However, it was such a mysterious substance that had the effect of shocking everyone.

In Yili Lake, where Asian carp once roamed and wreaked havoc, countless dead fish emerged and floated everywhere on the surface of the water.

In places with a high concentration of Asian carp, a casual net is full of dead fish.

There was even a video on the Internet of a shallow body of water where a large number of dead fish had been silted up, and people could walk over it as if they were crossing a bridge.

After Lake Erie, Lin Han immediately ran to Lake Ontario in New York State and killed the Asian carp in Lake Ontario.

Then he took people through Canada to Lake Huron and Lake Superior to continue cleaning up.

Although the Great Lakes are mainly owned by the United States, one-third of them belong to Canada.

However, in view of the relationship between Canada and the United States, when Vientiane talked with the US government, it had actually taken Canada into account, and Canada itself had no opinion and directly accepted Vientiane's governance plan.

After quickly cleaning up Lake Huron and Lake Superior, Lin Han rushed to the last stop of the Great Lakes, Lake Michigan, and quickly swept away the Asian carp in Lake Michigan with the same wind and clouds.

It took only half a month before and after the Asian carp that once ravaged the Great Lakes was swept away.

At this time, the agricultural departments of the United States and Canada can be busy.

After all, according to the agreement between Lin Han and Trump, Vientiane is only responsible for extermination, and as for the collection of corpses, it is still up to the US government to handle it itself.
