As soon as he hung upside down, the underground river where Du Xiaosheng was located immediately boiled, and a large group of piranhas jumped out of the water and bit at Du Xiaosheng.

Du Xiaosheng sneered, raised the ballista diagonally and shot it horizontally into the distance, and suddenly a harpoon shot straight into the corpses of six or seven piranhas not far away.

A large number of piranhas were attracted by the flesh and blood aura of their companions, and they all scrambled to swim in that direction.

Temporarily relieved of the pressure, he didn't dare to slack off, reached out and untied the biological and chemical weapon given by Yamada, and looked at it carefully.

It is a compressed gas cylinder with camouflage camouflage, a barometer and a valve with a safety lock.

According to Yamada, as long as the sprinkler head is partially inserted into the water and the valve is unscrewed, the biochemical toxins inside are released, killing all the piranhas.

But Du Xiaosheng knew that this thing was not so easy to use.

This is a perverted weapon researched by the little devils of the island country, if it is really as simple as a dry ice fire extinguisher, then it will be too dangerous for this thing to fall into the hands of the enemy.

Since Du Xiaosheng's debut, he has met many island people, among whom there are many fierce and upright people, such as the island swordsman in the extreme palace, who can't beat Du Xiaosheng but can afford to lose. Another example is the Surfing Association in extreme sports in the island country, after Du Xiaosheng challenged the 100-foot super wave, he took the initiative to express his respect and publicly apologized to Du Xiaosheng in the world media.

However, this Yamada in front of him is obviously not this kind of person, before coming, in the information of the national teams distributed by the Dragon Thorn, this guy who is known for his cunning and ruthlessness was marked as the focus of attention by the Dragon Thorn team.

At this time, Du Xiaosheng hung upside down and picked up the can of biological and chemical weapons, and began to check the external display screen on the outside of the can.

As a top special combat member officially graduated from the U.S. Kuangfunia Marine Corps, Du Xiaosheng relied on the super brain domain transformed by the fifth-level perfect person to crack the code and dismantle the bomb. The bullet aspect is quite high, so if the other party wants to fool him, it is easy for him to see through it at a glance.

"I've arrived at the target location, what is the use of this biochemical bottle?" The distance of dozens of meters is not too far, and Du Xiaosheng shouted directly.

Yamada shouted, "There's no time, you just use it as I say." ”

Du Xiaosheng sneered and said, "Okay, if you don't want to say it, then just hold it up." It's not bad to see you feed the fish here. ”

The raft of a Canadian special forces soldier was about to fall apart at this time, and when he heard Du Xiaosheng's words, he was furious and raised his gun and pointed it at him and said: "You Chinese people have a saying, it is called to spend the belly of a gentleman with the heart of a villain, if you don't do it, we will be finished, do you want to watch us die?" ”

When the others heard this, they began to echo the Canadian special forces, and the scene became extremely noisy for a while.

Du Xiaosheng didn't say a word, and directly operated on the keypad fan lock of the biochemical weapon a few times, and suddenly the automatic defense system of the biochemical lock was immediately activated.

As the LCD screen of the gas cylinder quickly lit up, a one-minute countdown quickly flashed red, and the camouflage shell quickly peeled off, revealing a brushed silver liner inside.

On top of the inner tank, a translucent bulletproof glass showed that two groups of liquids of different colors in the two spiral tubes were rapidly mixing, and a pale green gas quickly filled the transparent inner tank.

"Are you crazy? The poisonous gas in this poison gas cylinder is enough to poison tens of thousands of people, and if you don't enter the password correctly, it will explode in half a minute. Yamada shouted in surprise when he saw the light of the biochemical bottle come on.

Du Xiaosheng was also taken aback when he heard this, he gritted his teeth and said fiercely: "Yamada, you are so vicious, we are here to kill Cangzha this time, do you want the villagers here to accompany the burial?" ”

Yamada roared loudly: "Yaga, they are all accomplices of drug dealers, and killing them is not only without fault but meritorious. Let's not talk about this for now, you do what I say, first enter the stop password, and then adjust the toxin volatilization meter to ...... The evaporation rate is ......"

Hearing a series of data shouted by Yamada, Natalia and the others' faces changed, if Du Xiaosheng had just unscrewed the outermost gas valve directly as Yamada said at the beginning, the toxins sprayed out inside might be very small, but due to the internal cavity pressure, this gas will definitely not be completely dissolved in water, and when the time comes, some bubbles will emerge from the water, so Du Xiaosheng, who is facing these gases with his head down, will only have a dead end.

At this time, after Du Xiaosheng adjusted according to the data given by Yamada, after setting a timer, he directly sank the entire tank of biochemical poison gas into the water, and then he himself quickly swung forward, grabbed the depression of a rock wall above the cave with one hand, and hung the whole person upstream.

Seeing Du Xiaosheng's movements, Yamada immediately shouted: "No, this bottle is lightweight, and when the fish corpse floats up, it will be difficult to find it back!" ”

However, where did Du Xiaosheng pay attention to his words, seeing some extremely fine bubbles in the water coming out, Du Xiaosheng hurriedly covered his mouth and nose, and at the same time secretly manipulated the ultra-nano amphibious protective suit to protect all parts of his body tightly.

To say that this little devil's biochemical weapon is indeed powerful, this thing has only begun to release in less than ten seconds, and the originally boiling water surface instantly quieted down, and the piranhas who were still desperately fighting for food one second ago were like harvested wheat, turning up their white bellies layer after layer like harvested wheat.

This process was so fast that everyone could see the death of a large number of piranhas at a speed that was almost visible to the naked eye, and the entire underground dark river was instantly covered with countless piranha corpses, with white bellies everywhere, and a huge fishy smell overflowed from the river in an instant.

A large number of dead fish carcasses are slowly buffering downstream, but new carcasses continue to float.

The special forces sitting on the boat all had their mouths wide and held flashlights to shine around.

As far as the eye can see, it has become a sea of dead fish, and no one knows how many piranhas have died, probably thousands or more.

If the water of these underground rivers could carry these corpses to the Mekong, I don't know what a terrifying and spectacular picture it would be.

The boat continued to move forward, and every time the people flicked the oars, they could barely see the water of the dark river.

Originally, it was almost invincible in this underground dark river, but at this time, in just a few seconds, these nearly 10,000 piranhas were all wiped out in an instant!

"How? This thing is amazing, right? Yamada looked at the dead piranhas around him, and said proudly and regretfully: "According to the plan, if we can enter Cangza's lair, as long as this tank of poison gas is detonated, all the creatures in a radius of several miles will die, and we can solve Cangzha without a single soldier." It's a pity that Toussaint ruined my plan! ”
