Seven Hundred and Ninety-Four Ways to Survive (3)
The swarm of insects came faster than expected.
As soon as the convoy drove onto the highway, Ye Han heard a faint buzzing sound.
At first, the sound was very small, and his ears automatically ignored it, but the buzzing sound soon became extremely clear, low and powerful, and no one's ears could ignore it.
Ye Han suddenly realized that this must be the sound of flying ants flapping their wings!
He immediately opened the top cover and got out... The buzzing sound outside the car had reached the point of being overwhelming, and it was impossible to tell where the sound came from.
Ye Han looked around and was shocked to find that the sky in front of him was full of small black dots flapping their wings, and they were flying very fast. It seemed that they would fly over in a short time.
He also wanted to see if there were any flying ants coming from the south, but this road was east-west, and there were dense primeval forests on both sides of the road. The tall trees blocked the view, and he could not see the sky in the south at all.
The infrasonic cannons on the armored vehicles in front began to rotate, and Ye Han quickly retreated into the armored vehicle: "Liu Bin, do you know how to use the infrasonic cannon?"
"How should I know?" Liu Bin grinned helplessly.
There were so many switch buttons in front of him, who knew which one could control the infrasonic cannon.
"Forget it, let the Americans deal with it." Ye Han said.
Before the swarm of insects flew over the convoy, the Americans turned on all the infrasonic cannons. The infrasonic waves that were inaudible to human ears flew in all directions with the convoy as the center. The flying ants in the air suddenly scattered to the left and right, and some of them simply flapped their wings and flew high, wishing to hide as far away as possible.
Everyone was incredible. They didn't expect the infrasonic cannon to be so effective against flying ants!
The frequency of the infrasonic cannon has been adjusted several times. Although it is not capable of directly killing giant insects, it can already resonate with the internal organs of giant ants, thereby achieving the purpose of killing giant ants.
Although flying ants are not giant ants, they are developed from giant ants. Their internal structure has many similarities with African giant ants. The effect of infrasonic cannons against flying ants is indeed not as good as that of giant ants, but it can also achieve the purpose of expelling insect swarms.
Speaking of this, it was also an accident. Not only is the physiological structure of giant ants not suitable for flying, but the nerves and senses are also not suitable for flying. Therefore, when aliens created flying ants, they strengthened the nervous system, sensory cells and motor ability of flying ants.
In other words, flying ants are much more sensitive than stupid giant ants. If giant ants encounter infrasonic cannons, they will attack regardless of life and death under the drive of aliens, but flying ants will touch sensitive nerves as long as they are slightly exposed to infrasonic waves, so they instinctively avoid infrasonic waves.
Ye Han could not know such a deep reason. He only knew that infrasonic cannons were very effective against flying ants. He even thought that infrasonic cannons could be used to deal with flying ants in the future, such as deploying a large number of infrasonic cannons on the Nile River.
The convoy continued to move forward, and the swarm of insects separated to the left and right in front of the convoy, and then reunited after the convoy passed, just like deliberately making way for the convoy.
If the aliens hiding in the dark saw this scene, they would definitely be furious.
The infrasonic cannon was so effective that the Americans felt that it was a waste of resources to open all the infrasonic cannons, so they simply turned off half of them. As a result, the remaining infrasonic cannons could still be prepared to expel the flying ants, so the Americans decided to fire in shifts to avoid damaging the equipment due to long-term use.
In this way, the convoy continued to move eastward under the shadow of the swarm of insects. It was not known whether the swarm of insects was too large or whether the swarm of insects was always hovering near the convoy. In short, the buzzing of the flying ants never stopped, and the flying ants in sight did not decrease at all, until the sky gradually darkened and the buzzing sound in the sky gradually dissipated.
Ye Han felt very strange and couldn't understand why the flying ants were silent. He lifted the top cover a little to observe and found that the jungle was full of flying ants landing. The wings of flying ants were not very clear in the night vision goggles, but Ye Han had dealt with giant ants a lot and could see that the posture of flying ants was different from that of giant ants!
Landing at night, this phenomenon aroused Ye Han's interest.
Based on his understanding of African giant ants,
Whether it is ordinary giant ants or spider ants, they are species that do not distinguish between day and night, or in other words, as long as the aliens need them, the ant colony can be dispatched at any time.
It is said that flying ants should have inherited this characteristic, but now it seems that this is not the case. Moreover, from Ye Han's observation, flying ants seem to be very unaccustomed to the dark night. Not only do they not have the calmness of giant ants and spider ants, but they are confused and at a loss.
Ye Han couldn't think of any connection between flying and the night, but he soon remembered another thing: birds have excellent eyesight, such as eagles and pigeons.
The giant ants are just the opposite. They live underground all year round and rely on their sense of smell and touch to survive. Their eyesight is terrible!
He couldn't help but secretly guess, could it be that the flying ants land at night because of their poor eyesight?
The more Ye Han thought about it, the more he felt that it made sense. No matter what time it is, flying requires good eyesight. The giant ants are either blind or nearsighted, and they are not suitable for flying at all!
It is true that the aliens' bioengineering technology is extremely powerful and can consciously enhance the vision of flying ants. The problem is that ants have lived underground since the dinosaur era. Living by smell and touch has long become the instinct of ants, and it is an instinct written in their genes. Even if flying ants have strong eyesight, it is still unknown whether they are used to using their eyesight!
After thinking for a while, Ye Han suddenly laughed dumbly, thinking, why am I thinking about these things? Even if I know why flying ants are alert at night, can I use this to destroy the ant colony?
Besides, everything was just his guess, and it was not easy to prove it.
The flying ants stopped flying, and both the Chinese and American sides put down their worries. If the road conditions were not so bad, they would have rushed forward at full speed and reached the White Nile in one breath.
The actual situation was that the night not only affected the flying ants, but also the speed of the convoy. It was good enough to run 30 kilometers per hour on average. At this speed, it would take a full fourteen hours to reach the White Nile!
Fourteen hours is not long, but how could the aliens give up? Even if the flying ants are unusable, there are still giant ants and spider ants!
Ye Han really guessed it. The more you fear something, the more it will come. At more than eleven o'clock at night, the armored vehicle in front suddenly stopped, and the harsh brake sound spread all over the field.
Luo Qi, who was driving, stepped on the brakes... I don't know what happened to other cars, but Ye Han's car must change drivers every two hours to avoid fatigue driving. .
Luo Qi's reaction was not slow, but the distance was too close, and he crashed into the armored vehicle in front of him. Fortunately, the speed was not fast, and neither vehicle was damaged.
Today's condition is extremely bad, crying.
