“Let's get going. I can't wait to start exploring！” Lee stomped excitedly and chatters ceaselessly in Jon's ear as he was checking the equipment. Lee and Jon are deep-sea explorers, also Lee is a mechanic and Jon is a technology geek. Their private submarine once won seventh place in World Science and Design Competition. Their footprints have been all over the Pacific and Arctic oceans. The highest record they ever held was nine kilometers deep. This time, however, the forthcoming challenge they will take is exploring a whole new world they have never reached - 10,000 meters deep.

 

Jon had finished checking the equipment. All indicators and data are normal and running. He stared a few times at the instrument in one part and muttered something." Five hundred and thirty-nine kilometers, six hundred and fifty-two, could be more than..." "Hello? Hello? Are you okay? You have broken your habit of staring into space again, my friend." Lee patted glassy-eyed Jon on the shoulder. It may be a little tiring, or it may be the anticipation of the adventure ahead.

 

At 10:36 a.m., they arrived at their destination in a ship carrying a submarine. After making the final preparations, they went into the submarine. The ship's crane slowly lowered the submarine into the sea. Lee and Jon gradually disappeared from thesurface.

 

The interior space of a submarine was relatively narrow because large body size and non-streamline could increase the resistance acting on the submarine. Through a piece of bullet-proof glass that was resistant to high pressure, they could get a clear view of the sea world they are in.

 

Although they modified the spatial distribution of the submarines so that they felt there was plenty of room. However, compared with the vast ocean, they are just a leaf.

 

5 meters, 10 meters, 23 meters... They began to dive. Slowly a variety of Marine life began to appear around it. The world here was wonderful and awesome. Several sharks were circling their submarine, but the two were not nervous. They understood that sharks are one of the most docile animals in the world. 224 meters, 229 meters... The ecology here was still rich and diverse. Giant shoals of sardines formed a moving black shadow. Many other amazing species don't have names that shine through here.

 

An hour later, they reached a depth of 6,483 meters. The light faded away as the submarine dived. It's a dark world, full of creatures that no one knows about. They turned on the searchlights and continued their dive.

 

"9,983 meters, 9,989 meters, 9,994 meters, 10,000 meters! We did it, friend." They both shouted excitedly. "I suggest we open a bottle of champagne and celebrate when we get back," Lee said. Positively, it was a historic moment of honor for them.

 

Bang! As Jon spoke, their submarine was hit hard on the seabed by a force. "What's the matter? There's nothing in the way!" Lee said. "To be exact, we were hit by something. Damn, the dashboard is not working!" Jon replied calmly. The piston of the submarine's ballast tank was knocked out, which meant that they could not control the submarine's buoyancy from the tank. They were trying to stay calm and checked the damage to the submarine.

 

"Hey, Lee, put down the wrench. You listen carefully. My god, what's that noise?" Strange sounds were heard all around them. The voice was harsh and sounded like some kind of wild animal. The searchlights could still be turned on. When they turned on the light, they were frighten broken bravery by what they saw.

 

In front of them was a huge beast of prey. It's extremely ugly. The huge mouth and teeth about the size of a mammoth can tear anything apart. It was a heteromorphic creature because it looked like a fish, but its huge body doesn’t look like the fish we familiar with. Its eyes were empty and lifeless, just white. A basking shark came slowly as if God had sent it to ease the tension. But, in a flash, the blood gushed out. The basking shark was ripped apart by the beast. At this point, Lee and Jon realized that they have entered the territory of the beast. Lee and Jon both gasped. They did not know whether the beast would attack them the next second. That’s the fact that even the most ambitious explorers fear the unknown.

 

It's been deadlocked for about fifteen minutes. They felt hopeless and even ready to die. For a split second, a bold idea, which is the only one that would give them a chance at salvation, came to Jon. "Lee, eject the rear airbag and blow it up quickly. I'll start the catapult." "Catapult? Blow up airbags? You're kidding! Our gravity balance would be out of balance and our oxygen supply would be cut off!" "It's the only way to keep us alive. Don't talk nonsense. Just do it!" They blew the airbag off. The gas, which had been trapped in the airbag, quickly hit the water and created a huge impact. The beast was caught flat-footed by the sudden onslaught. The submarine was also pushed up to 9, 313 meters by the upward thrust. Fortunately, without the system of gravity, they were slowly making their way upward. Unfortunately, their oxygen content was very limited. They had to last forty-eight minutes.

 

The submarine rose to an altitude of six kilometers. Their submarines were churning, buoyed by liquid buoyancy and weak currents. "Oh my god, it's so hard. I feel like I'm carsick." Lee complained. "Say no more. We're running out of oxygen. From now on, take a small breath, just like with red wine." Jon responded.

 

They kept their cool and floated across the Atlantic. At last, after another twenty-six minutes, they rose to the surface. "Thank god we survived." "Jon sighed. "Well, my friend, I have called for international help. We can go home in a minute." Lee said.

 

They set a new record for submarines, but they never went to sea again.

 

“快走吧。我等不及要开始探索了!”在乔恩检查设备时，李兴奋地跺脚，不停地在他耳边喋喋不休。李和乔恩是深海探险家，李是机械师，乔恩是科技狂。他们的私人潜艇曾在世界科学与设计竞赛中获得第七名。它们的足迹遍布太平洋和北冰洋。他们保持的最高记录是九千米深。然而，这一次，他们即将面临的挑战是探索一个他们从未到达过的全新世界，一万米深。

 

乔恩检查完设备。所有指示灯和数据正常运行。他一边盯着仪器看了几遍，嘴里咕哝着什么。“五百三十九公里，六百五十二公里，可能比……”“喂，喂?你还好吗? 你又犯了发呆的习惯了，老朋友。”李拍了拍目光呆滞的乔恩的肩膀。他可能有点累了，也可能是对未来冒险的期待。

上午10点36分，他们乘坐一艘载有潜水艇的船抵达目的地。做了最后的准备后，他们进入了潜艇。船上的起重机把潜水艇慢慢地放入海中。李和乔恩渐渐从海平面中消失了。

 

由于潜艇较大的体积和会增加作用在潜艇上的阻力非流线型设计，这使得潜艇内部空间相对狭窄。通过一块抗高压的防弹玻璃，他们可以清楚地看到他们所在的海洋世界。尽管他们修改了潜艇的空间分布以便他们觉得有足够的空间。

 

然而，与浩瀚的海洋相比，它们也只是一片孤叶。

 

5米，10米，23米……他们开始下潜。慢慢地，各种各样的海洋生物开始出现在他们周围。这里的世界是美好且令人敬畏的。有几条鲨鱼围着他们的潜水艇，但这两个人并不紧张。他们知道鲨鱼是世界上最温顺的动物之一。224米，229米……这里的生态仍然丰富多样。巨大的沙丁鱼群形成了一个移动的黑影。 许多其他神奇的物种的名字并没有在这里闪闪发光。

 

一小时后，他们到了六千四百八十三米深的地方。 潜水艇潜入深海中，光线逐渐消失。这是一个黑暗的世界，到处都是无人知晓的生物。他们打开探照灯，继续下潜。

 

“9983米，9989米，9994米，10000米!我们做到了，兄弟！”他们俩兴奋地喊道。李说:“我建议我们开瓶香槟，回去的时候庆祝一下。”毋庸置疑，这对他们来说是一个历史性的荣誉时刻。

 

砰! 就在乔恩说话的时候，他们的潜艇被一股力量重重地砸在了海床上。“怎么了?出什么事了? 面前什么也没有!”李说。“确切地说，我们被什么东西撞了。该死，仪表盘坏了!”乔恩在尝试平静地回答。潜艇压载舱的活塞坏掉了，这意味着他们无法从舱中控制潜艇的浮力。他们试图保持冷静，检查潜艇的损坏情况。

 

“嘿，李，把扳手放下。你仔细听。天哪，那是什么声音?”他们周围听到了奇怪的声音。声音很刺耳，听起来像是某种野兽的声音。探照灯仍然可以打开。当他们打开灯时，他们被眼前的景象吓得胆战心惊。

 

在他们面前是一头巨大的猛兽。它非常丑陋。巨大的嘴和猛犸象大小的牙齿可以撕裂任何东西。它是一种异型生物，因为它看起来像鱼，但它巨大的身体看起来不像我们熟悉的鱼类生物。它的眼睛空洞而毫无生气，只有白色。一条姥鲨慢慢地游过来，好像是上帝派它来缓和紧张气氛的。但是，刹那间，鲜血涌了出来。姥鲨被野兽撕成了碎片。这时，李和乔恩意识到他们已经进入了野兽的领地。李和乔恩都倒吸了一口气。他们不知道下一秒野兽是否会攻击他们。是啊，即使是最雄心勃勃的探险家也会害怕未知。

 

已经僵持了十五分钟了。他们感到绝望，甚至准备赴死。在那一刹那，一个大胆的想法出现在乔恩的脑海里，这也是唯一一个能让他们得救的想法。“李，把气囊弹出然后迅速引爆。我来启动弹射器。”“弹射器?引爆气囊?你在开玩笑吧!我们的重力平衡会失去平衡，氧气供应会被切断!”“这是让我们活下去的唯一办法。别说废话，照做!”他们把气囊引爆了。存储在安全气囊中的气体迅速涌入水中，产生了巨大的冲击力。那野兽被这突然的爆炸吓得不知所措。潜艇也被向上的推力推到9313米。幸运的是，没有了重力系统，他们正在慢慢地向上移动。不幸的是，它们的含氧量非常有限。他们必须挺过至少48分钟。

 

潜艇上升到六公里的高度。他们的潜艇在液体浮力和弱洋流的作用下搅动着。

 

“哦，天哪，太难了。我觉得我晕车了。”李抱怨道。“别再多说话了。我们的氧气快用完了。从现在开始，轻轻呼吸，就像喝红酒一样。”乔恩回应道。他们保持冷静，漂洋过海。最后，又过了二十六分钟，他们浮出水面。“谢天谢地，我们活了下来。”乔恩叹了口气。“我已经发射国际卫星求助信号了。我们马上就可以回家了。”李说。

 

他们所创造的记录刷新了人们对于潜水艇的认知，可惜自此之后，他们再也没下过海了。
