There was an unusual accident in the history of nuclear testing.

One day, Dr. sloda, a famous Canadian nuclear scientist, was doing experiments in the laboratory to study the critical mass and involution of uranium (235).

Suddenly, the screwdriver in his hand accidentally fell to the ground.

Dr. sloda uses a screwdriver to move two pieces of uranium on the slide rail that are less than the critical mass to test their critical mass and alignment. When the screwdriver falls underground, the two pieces of uranium suddenly slide together, the weight exceeds the critical mass, and emit a blue flash.

This shows that the chain reaction (i.e. nuclear fission) of this uranium greater than the critical mass has begun under the action of neutrons, which will trigger a nuclear explosion in an instant.

At this time, it was too late for Dr. sloda to pick up the screwdriver on the ground and remove the two uranium. However, if the two uranium were not separated immediately, an unexpected nuclear disaster would be inevitable.

In an extremely urgent situation, Dr. sloda had no time to consider the harm of radioactivity to human body, and recklessly broke two pieces of uranium with both hands -- a terrible nuclear accident was avoided.

Then, Dr. sloda looked calm and said to the stunned people around him: you should still have no problem. I guess you can't.

Dr. sroda died nine days after he was sent to the hospital because he was exposed to a large amount of nuclear radiation.

For this reason, the Canadian government solemnly commended sloda, and people also gave him high praise, calling him the man who broke the atomic bomb with his hands.

There is not much research on the history of nuclear testing. Of course, I don't know Dr. sroda's story. However, after the nuclear bomb was lifted, the steel barrel still sounded a drip alarm, and saw tieliao shouting "double-layer nuclear fission" in horror, I immediately realized that things were going to be worse.

Completely out of instinct, he jumped on the miniature nuclear bomb used to detonate the hydrogen bomb and fell from the platform into the pit.

After the nuclear fission of the nuclear bomb, let alone whether it will explode, but after the nuclear fission, it will certainly release the nuclear radiation that kills all living creatures in front of us at the moment when the alarm buzzes.

After all, this miniature nuclear warhead is hundreds of times larger than Dr. sloda's time in the laboratory -- once the alarm stops, no one can escape bad luck.

Therefore, someone must stand up and make sacrifices like Dr. sroda in order to avoid other people from deadly nuclear radiation.

Fang Yuan stood up.

Perhaps he would regret his stupidity after he fell into the pit with a nuclear bomb.

But to be sure, he was also very pleased -- otherwise, he would not have been so calm when he shouted that sentence to the king of nine yous: I finally paid off your debt!

He finally paid off my debt!

In his ignorance, Jiuyou king was dragged by tieliao and ran along the roadway to the ground (the guards of the underground ancient city, when escaping from the ancient city, of course, had to open the iron door of the roadway, and no one closed it after running over). This voice always echoed in his mind.

When the eyes suddenly lit up, they had come to the ground.

At this time, the whole world seemed to have trembled. Looking at the birds and animals on Nanshan Mountain, they had evacuated at the fastest speed long before the underground magma roared to spray out.

Animals have an incomprehensible ability to predict natural disasters such as earthquakes.

Those Northern Dynasty people who fled the ancient city first also disappeared, but the secret reception personnel sent by Longtou still remained on the south side of the entrance and exit and were preparing to evacuate.

Li Jiaxing is the leader of this latent response task.

When the residents of South Sichuan county in Huaxia retreated, he received the news that the volcano was about to erupt at any time and immediately asked Longtou whether to give up the task next.

The faucet didn't speak. After a moment of silence on the phone, he cut off the phone.

Li Jiaxing understood: he must stick to the last minute.

Although he took people back to China after asking for instructions, Longtou wouldn't say anything, let alone blame him for being greedy for life and afraid of death -- he felt that Longtou wished he could stick to it more.

Because down there are his comrades who may be alive.

The whole latent rescue team, with a total of 17 people and six cars hidden at the foot of the mountain (the volcano is about to erupt, and no one can be sure where the magma will suddenly erupt, so the whole border is in a mess. Li Jiaxing, who has long been lurking here, can take the opportunity to get a car), and are ready to evacuate at any time.

When a large number of people from the Northern Dynasty fled in panic from the underground ancient city, no one looked South and shouted and ran to the north.

Li Jiaxing, hidden hundreds of meters away from the south of the entrance and exit, can see clearly with a telescope.

After no more people from the Northern Dynasty escaped, he immediately ordered: no longer hide their whereabouts, jump at the entrance of the underground ancient city as fast as possible!

He hoped that before the eruption of the volcano, he could run into the underground ancient city to see if he could search and rescue his living comrades in arms.

No one hesitated.

For soldiers, obeying orders is their bounden duty. Otherwise, there would not be so many people falling on the road of charging, let alone winning victories again and again.

They quickly rushed into the first floor of the underground ancient city - but then they heard the rumbling sound getting louder and louder, the sulfur smell getting thicker and thicker, and the temperature getting higher and higher.

The volcano is about to erupt.

In desperation, Li Jiaxing had to order: terminate the search task, all personnel immediately withdraw to the ground and return to the territory.

"Look, someone is coming out again!"

When Li Jiaxing contacted Longtou again and reported to him that his party had to evacuate urgently, he suddenly heard a comrade in arms shouting.

Li Jiaxing turned around and saw three people running out from the entrance and exit hundreds of meters away.

After the three men came out, they rushed to them without hesitation.

Whether animals or people (people are also high-level animals), when they have to escape in the face of unmanageable danger, the instinct in the subconscious will play a key role.

Just like those northern Koreans who just escaped not long ago, they rushed out and ran to the north without thinking about it -- that's their hometown, and subconsciously, that's the safest place.

So, what about these three people?

After rushing out, they ran to the South without hesitation -- is it that Huaxia in the south is the safest place in their subconscious mind?

"Hide and get ready for battle!"

Li Jiaxing immediately gave a low drink, raised his hand and waved it fiercely.

Seventeen people immediately hid with the fastest speed, and the muzzle of the gun was aimed at the people who ran over.

Li Jiaxing clenched the telescope with both hands and locked the faces of the three people.

Unfortunately, among the three men, except that the strange woman could see the appearance, the other two men just rolled in the cesspit and couldn't see who they were at all.

But as they ran closer and closer, Li Jiaxing and others could hear a man yelling in Chinese: "run! Special, you run quickly! "

The man was scolding the woman who was dragged by him.

It's our people!

Li Jiaxing suddenly woke up and jumped out from behind the bunker.

"Run, don't you run fast? Why are you so slow! I know you want to go back and save Fangyuan, but he is dead, dead! "

Tie Liao dragged the nine Youwang who was like a sleepwalker, but always looked back when he ran passively. When he roared these words, he suddenly heard someone drinking: "password!"

"The halberd sank into the sand!"

Without thinking about it, tieliao shouted this idiom.

The halberd and sand sinking comes from the poem "Red Cliff" by Du Mu of the Tang Dynasty: the halberd and sand sinking iron is not sold, and he will recognize the previous dynasty. The east wind does not go with Zhou Lang, and the copper sparrow spring locks Erqiao deeply.

The moral is that the broken halberd sank in the sand and became scrap iron. It describes the failure as very tragic.

Breaking halberds and sinking sand is not only the code of tieliao and others' action, but also the password.

Before they took action, they had a premonition that this mission was a near death and no return. Therefore, they chose this idiom with quite tragic meaning as the code and password.

"It's our people. They're still alive! Come on, come on, pick up, pick up! "

At the moment of hearing the "broken halberd sinking into the sand", Li Jiaxing suddenly burst into tears and roared with all his strength. He threw away his telescope and rushed at tieliao. However, because he was too excited, he tripped heavily on the ground by a tree root protruding from the ground.

"Get up, get up!"

Tieliao didn't believe what he said. After he (and Qin Jiehua) saw the reinforcements, the powerful and invincible King Jiuyou would trip over a random stone and hit another random stone on his forehead.

Fortunately, other people's children are invulnerable, so they won't be beaten, but they're embarrassed enough.

"Get up, what are you doing! Fang Yuan is dead. You can't save him! The volcano has erupted! Get up and run! "

Tie Liao dragged the king of Jiuyou, but it was like a delusion to drag the whole earth up.

The woman half knelt on the ground and looked down at the rubble under her feet. Her long hair hung down and covered her ordinary face, but she didn't move like a statue.

"You're stupid!"

Tieliao roared angrily and kicked her in the ribs, hoping to remind her.

At this moment, he has completely forgotten that the king of Jiuyou is the enemy of the whole China. It is the most correct to take the opportunity to kill her -- or to persuade her to go back to the underground ancient city to die.

He could only see that the powerful king Jiuyou had no soul after hearing the words that Fang Yuan shouted before he died.

Did she fall in love with Fangyuan?

At this time, tieliao certainly didn't think of this problem. He just felt that he had to take her away when the volcanic magma filled the whole underground city.

"Come on, help me pull this crazy woman up!"

After Li Jiaxing led people to rush over, tie Liao shouted without thinking.

Two special soldiers immediately rushed over, put their arms on the king of Jiuyou, and tried to pull her up from the ground -- they couldn't move.

I can't drag it. The king of Jiuyou seems to have roots and is connected with the earth.

But she raised her head, looked at tieliao and said softly, "he said, he has paid off his debt to me."

"Yes, yes, I heard it. We all heard it. Fang Yuan paid off his debt to you before he died!"

Tie Liao pulled up the wrist of the nine Youwang with both hands.

"But he doesn't owe me, he never owes me -- he doesn't know, he doesn't know, he never owes me anything. No, I have to go back to him and make it clear to him. "

The nine Youwang murmured, and his arms shook violently -- tieliao, and the two special soldiers, as if they had been severely electrocuted by a high-voltage electric stick, suddenly fell back out.

"I have to go back and make it clear to him that he doesn't owe me anything."

When the nine Youwang sleepwalking finished this sentence, people had spread their wings and flew to the entrance and exit of the ancient city like a roc bird.

In a flash.
