Xiao Yuan was surprised: "Only three meters? This is too different!"
"Who knows, it seems that southern worms are smaller than northern worms. More than three meters long are already relatively large bugs, and they are usually about two meters long." Shen Hao said.
"There's no bigger one?" Ye Han was surprised.
"It's not impossible, let's put it this way, what swims in the water is bigger than what crawls on the ground, and what crawls on the ground is bigger than what flies in the sky. The largest flying insect here on the Marrow River is less than one and a half meters long." Shen Hao said.
Xiao Yuan was speechless. Not to mention the giant cockroaches that are more than ten or twenty meters long in the north. Even the giant mantis ants can grow to more than four meters long. I heard that there are giant centipedes more than six meters long on Bang Island. Why?
Have the giant insects in the south shrunk so much?
"Instructor Ye, is the small size of the southern insect related to the temperature?" The new team member who had been silent until now suddenly asked.
The new team member's name is Chi Wei. He has just been promoted from a student to an intern team member, and he won't be able to change his naming habit for a while.
"It's possible." Ye Han nodded, "Yes, the theory class was not in vain."
How to operate power armor is only the main course in the sports equipment academy. In addition, there are various theoretical courses, and giant insects are also one of the main courses in the academy.
Shen Hao blinked in confusion: "The temperature here is high, so the giant insects are smaller?"
"You can say that." Ye Han said with a smile, "Strictly speaking, it has something to do with heat dissipation."
"Still don't understand." Shen Hao shook his head.
Ye Han explained: "Let's put it this way, insects are relatively low-level animals and do not have heat dissipation organs such as sweat glands. The larger they are, the more heat they generate during exercise. The weather here is hot. If they are too big, they will generate more heat during exercise."
The heat can kill giant insects, so the small size of southern insects is probably related to the temperature."
Shen Hao looked thoughtful: "It seems to make sense. Bugs in the water don't need to dissipate heat, so they are larger... But aren't there giant cockroaches more than 20 meters long in the north? How do those things dissipate heat?"
"I don't understand this either." Ye Han shrugged, "But giant cockroaches only move at night, maybe because they are afraid of the heat."
"No, although there are no giant insects that are too big here in the Marrow River, there are large giant insects in neighboring provinces and Southeast Asia. How to explain this?" Shen Hao asked again.
"Perhaps these giant insects have evolved some kind of heat dissipation ability. In a word, those who can survive can adapt to the environment, and those who cannot adapt will die." At this point, Ye Han chuckled, "Let's just chat casually,
Let Beidu study this kind of messy matter."
The gunshots outside the car had become very loud. Ye Han turned on the surveillance screen to check the situation outside the car. Unsurprisingly, he saw a machine gun tower firing. Tracer bullets flew into the dark night. He didn't know what was going on.
Didn't hit the target, but the shooting frequency was not low anyway.
Not only were the machine gun towers firing, but there were also several armored vehicles parked on the side of the road, ready for action.
Ye Han asked curiously: "What does the machine gun tower use to determine the target position? Is it radar?"
Shen Hao replied: "Radar is responsible for positioning, and ultrasonic and optical photography are responsible for determining whether it is a giant insect."
"So complicated?" Xiao Yuan exclaimed.
"It's not that exaggerated. They are all low-power devices, and the detection range is no more than one kilometer."
The armored vehicle drove past the city's defense line, which was under heavy fire. Ye Han turned the camera on the roof of the vehicle to carefully observe the situation nearby.
After driving more than 400 meters away from the defense line, a large mosquito suddenly appeared on the green screen. Before Ye Han could see the appearance of the giant mosquito clearly, a tracer bullet had already hit the giant mosquito's thoracic section, killing the giant mosquito as a chest.
Truncate.
The broken giant mosquito dragged its broken wings, like the seeds of a maple tree, spinning and falling.
Then an unnamed flying insect broke into the screen. The giant insect was hit by two bullets at the same time and shattered into three pieces in the air.
Ye Han silently turned off the screen and stopped looking at the situation outside.
It was said that the scale of the insect plague in the south was poor. He had always thought that the giant insects in the south were scattered and insignificant. Now he realized that although the giant insects here were fighting independently, their scale was not much smaller than that in the north.
He looked at Shen Hao and asked: "How did you survive when the Marrow River had no defense system?"
"What else can I do? Just don't go out at night. If you encounter bugs when you go out, you will be unlucky." Shen Hao said, "But it was true that there were not so many bugs at that time."
Ye Han looked back at Suihe City. There were basically no street lights or landscape lights in the urban area, but there were still a lot of lights coming from the buildings. Insects have phototaxis. If there was no light in the city, would the situation be better?
But he was just thinking about it. With so many people in Xuhe City, it was impossible for him to not think of this, and it was not his turn as an outsider to worry about it.
A few minutes later, gunshots were no longer heard in the armored vehicle far away from the urban area of Muihe, but the distance was still a bit close. It drove forward for a while, and then under the guidance of Shen Hao, it drove off the road protected by the machine gun tower and drove away.
The last concrete road leads to nowhere.
The cement road has not been used for a long time. There are dead branches and leaves everywhere on the road, and weeds stubbornly poke their heads out of the cracks. The vegetation on both sides is much denser than that near the road, and even the big tree with roots more than ten meters high is
There are quite a few.
After leaving the road, Andong Li turned off his car lights as required and drove carefully with the vision provided by his night vision goggles. However, bright lights flickered in the forest from time to time, floating around like will-o'-the-wisps.
Shen Hao smiled: "It's okay, that's a firefly, a giant one."
"And there are fireflies?" Xiao Yuan immediately became interested, "Captain, can you go out and have a look?"
"Be honest, you'll be watching when I get there." Ye Han glared at Xiao Yuan.
Wearing armor and getting out of the roof hatch is definitely not a problem in terms of safety. It is impossible for giant insects to get into the car from the roof. The problem is that it can block the giant insects, but not ordinary insects. If a few mosquitoes fly into the car, it will be
Oh no.
Xiao Yuan grinned in disappointment and leaned over to the screen to take a quick look, but the night vision screen was full of green light, and it didn't feel like he was a child at all.
Watching fireflies is more immersive and atmospheric.
Shen Hao smiled and said: "Don't worry, you will see it later."
"Are there many fireflies?" Ye Han asked.
"Quite a few, especially in the woods."
Ye Han sighed: "When I was a child, I learned it in school. It was said that in order to study, the ancients would grab a bag of fireflies and take them home for lighting. If there were giant insects at that time, it would be enough for the scholar to grab one and take it home."
"Are you kidding?" Xiao Yuan said, "I have always wondered how it is possible to read the words on the book clearly when the fireflies have so much light. It's weird that you will be nearsighted if you use this thing for lighting. What else is there?
I just study with Xue Guang, is Xue Guang very visual?"
Ye Han couldn't help but laugh: "You kid, can't you bring your brain with you?"
