Chapter 246 Crisis (Second update, please vote for me)

Stealth means invisible to the naked eye, but radar can capture signals. Most aircraft have this function.

Radar invisibility means that the eyes can see, but the radar cannot capture the signal. For example, those drones that can fly at low altitude can bypass the radar search, but they cannot avoid people's eyes.

Some fighters with excellent performance can achieve both naked eye and radar stealth. They are truly stealth fighters.

But to achieve this effect, not only have special requirements for building materials, but also have very high requirements for various performance indicators of equipment.

In terms of cost, it is definitely not within the reach of ordinary people.

Even among the four nobles, only two have a large "aircraft" that can achieve both naked eye and radar invisibility.

As Xia Chujian gradually got used to it, she discovered that her Shao Siming black silver mecha could freely choose between two stealth modes.

Stealth to the naked eye, stealth to radar, or both.

Xia Chujian chose the same time without hesitation this time.

At the same time, invisibility requires more energy and lasts for a shorter time, but Xia Chujian doesn't care how much energy is used at this time, he just wants to be free and fly between the heaven and the earth as he pleases.

She passed between buildings, unable to be captured by any eyes or surveillance.

She even flew to the neighborhood next door to find the house Pingqiong bought.

Xia Chujian stopped at the window and looked for a while. It was dark inside and she couldn't see very clearly.

She turned on the infrared vision system on the helmet's eyepiece and found that the house was exactly the same as the day she and Ping Qiong visited the house.

There is no decoration yet...

She flew north to the outside of Mulan City again, wanting to see her own land.

With the speed at which she commanded the black and silver mecha, it only took a matter of minutes.

Ten minutes later, she floated above the high wall and took a deep breath.

Then, he flew around his piece of land again and didn't feel anything strange before flying back leisurely.

On the way back, she slowed down, wanting to enjoy more the fresh air under the night sky.

Mulan City in the middle of the night is actually not peaceful.

In the shadows of the streets, evil of all kinds is going on.

Xia Chu was expressionless when they met. He had dealt with three robbers, two murderers who were killing people, and a man with evil intentions because he was following a woman home from the night shift with a wet handkerchief in his hand.

When the man was about to cover the woman's face with the wet handkerchief from behind, Xia Chujian kicked him into the sky.

As for how he fell in the end and where he fell, it was none of her business.

The woman seemed to feel something, turned around in fear, and then ran faster.

Ahead, after the family members who came to pick her up met her, Xia Chujian left quietly.

By the time Xia Chujian returned home again, it was already three o'clock in the morning.

The early summer wind gently blew over her helmet.

Xia Chujian flew in gently and skillfully from the window.

Before I could take back my Shao Siming black silver mecha, I suddenly heard Liu Shun say at the door: "Master, there is something wrong with that big black dog opposite the door. It is already banging on the door."

Xia Chu's heart skipped a beat when he saw it.

She took a deep breath, and without taking back her Shao Siming black and silver mecha, she randomly pulled out a khaki work suit from the closet, put it on over the Shao Siming black and silver mecha, and then came out of the bedroom.

Liu Shun was stunned for a moment when he saw Xia Chujian's black and silver mecha helmet.

Its eyes glowed red, and after a while, it was sure that the person wearing a helmet in front of it was its owner.

Xia Chujian didn't care to hide her helmet in front of Liushun at this time, because this time, she didn't have to listen carefully to hear the movement on the other side.

At this time, the big black dog was not just barking, but actually banging on the door!

No matter how soundproofed the door is, it cannot block this physical movement.

Xia Chujian had an ominous premonition in his heart.

She rushed to the living room and opened the door.

The door on the opposite side was indeed shaken by the big black dog.

Xia Chujian immediately turned on the far-infrared night vision system function of Shao Siming's helmet's built-in eyepiece.

This function allows the helmet eyepiece to see through the far-infrared imaging system to see the scene behind the wall.

After opening it, she found that she could only see the entrance behind the door.

Behind the entrance, the far-infrared see-through function does not work.

Inside the entrance hall, the image of the big black dog desperately banging against the door appeared on the display screen of her helmet's eyepiece.

Xia Chujian immediately clenched his palm into a fist, knocked on the door lock, and said loudly: "Open the door, you can unlock the door from here."

The big black dog in the house heard it, and the crashing sound seemed to stop for a while. Then it seemed to understand what Xia Chujian meant, and began to stand upright on its two hind legs, and grabbed the door handle with its two front paws.

Not long after, there was a click, and the door was really opened by the big black dog!

It rushed out all at once, and Xia Chujian quickly got out of the way, otherwise she would be hit by the big black dog.

But the big black dog didn't hide away when he saw her like before. Instead, he barked at her even more loudly.

It seems that some unforeseen horror is about to come.

Xia Chujian knew that some animals had inexplicable premonitions about natural disasters.

Could it be that the big black dog had a premonition of some natural disaster?

When Xia Chu met, the first thing that came to his mind was the earthquake.

Then I thought about my little dog, why didn’t it feel anything?

Xia Chujian looked into the room while thinking wildly.

There was such a loud noise, but no one answered the door, not even a voice scolding the big black dog.

This isn't right.

Xia Chujian started to walk in and called out tentatively: "Wangyou! Yu Wangyou! Mr. Yu! Mrs. Yu! Are you at home?"

She screamed a few times before remembering that she was still wearing a Shao Siming mecha helmet. It would be difficult to explain if the Yu family saw her.

But just when she was about to put the helmet away, a few lines of subtitles suddenly appeared on the helmet's eye display.

"Extremely large doses of Teflon detected in the air."

"If you take off your helmet, you will be unconscious within three minutes."

"It is recommended not to take off your helmet."

Xia Chujian: "!!!"

Is there an excessive amount of Teflon in the air?!

Xia Chujian's chemistry score was okay, but she vaguely remembered that Teflon is a volatile gas that can cause coma.

Since the intelligent system of the mecha says there is an extra large dose, then there must be an extra large dose!

Then the people from the Yu family...

Xia Chujian immediately stopped, and then a few lines of words appeared on the eye display of the mecha's helmet.

"More and thicker methane is detected in the air!"

"Danger! Danger! Danger!"

"Please leave the scene immediately! Please leave the scene immediately! Please leave the scene immediately!"

Methane?!

Xia Chujian used his reasonable knowledge of chemistry to know that this was the main component of natural gas.

What's going on tonight?

Will the test focus on chemistry knowledge?

Xia Chujian muttered, feeling shocked and confused.

Because their building is an old building, it only has a very old natural gas pipeline system, which is our main energy source besides electricity.

For example, Xia Chujian's family and Xia Yuanfang like open fires when cooking and don't like to use induction cookers, so their home also has natural gas.

Natural gas has a characteristic. When its concentration in the air reaches 5%, it will explode when exposed to an open flame...

Xia Chujian's face changed drastically. When she quickly walked around the entrance and walked to the entrance of the Yu family's living room, the alarm prompts on the helmet display became increasingly dense.

"The methane content in the air is gradually increasing."

"We'll reach the critical point in ten minutes."
