Looking down from the sky, under the layers of fog, a minesweeper adrift on the vast sea surface looks so small, and the detection missions in the cold wind are being carried out one after another.

"Signal Transmission, Normal"

"Radar No. 1 is connected normally"

"Radar No. 2, normal"

....

"I'll leave everything to you here, I'll go up and keep an eye on it"

"Yes, Elder Xue, promise to complete the task"

Old man Xue patted Wang's shoulder on the head, turned around slowly with a cane, and ascended to the upper bridge escorted by two sailors. Entering the bridge, I saw several young men wearing glasses sitting in the bridge, their clothes exactly the same as the sailors' uniforms on the ship. After seeing Xue Lao come in, he immediately got up and saluted a military salute, and Xue Lao also returned a salute when he saw this, waved his hand and said, "You go on, don't worry about my old man." ”

"Yes! Heads. ”

After a few people sat down, Xue Lao's eyes fell on the huge radar display on the driver's platform, and then he took a key from his neck and inserted it into the center console. At the same time, a wide army-green curtain was torn off at the stern, revealing a mysterious large military radar full of antennas, which formed a reflective surface at one end, which was completely different from the small circular radar on the bow deck, and was protected by sailors with loaded guns and ammunition.

When Old Man Xue twisted the key in his hand, the radar in the stern of the ship was activated. Unlike the humming roar of the machinery in the bow, the radar was quiet, and its large curved surface rotated at a constant speed, as if a panacea had been applied underneath.

The captain in the bridge glanced at Old Man Xue and asked, "New equipment?" ”

"Well, 17 institutes have just been developed." Old man Xue replied.

"No wonder I haven't seen this model, has it been accepted?" The captain asked again.

"Not yet" Old Man Xue turned his head and glanced at him, then glanced at the other control panels and said, "Although it hasn't been accepted yet, I believe it's going to be soon." This thing is said to have a single-pulse measurement accuracy of an astonishing 0.2 density, and many people are red-eyed......"

On the bow deck, the heavy radar was constantly moving, and Liu Zizhen was staring intently at the radar wave in front of him with a headset. Beneath the vastness of the sea, the humming radar waves sink to the bottom of the sea through the schools of rushing fish. On the rolling seabed, the occasional school of fish that preys between the grass shuttles through and shakes up dust, and sometimes three or two fast fish flash into the darkness of the seabed, making the darkness of the seabed more mysterious.

Time passed minute by minute, Liu Zizhen gradually frowned, the expression on his face was uncertain, suddenly took off a headset, covered the left headset with his left hand, and played with the knob of the radar surface with his right hand from time to time.

"Could it be, not here?"

Standing at the door of the cabin, I suddenly said such a sentence for no reason, and even I felt a little surprised. Hearing this, Li Xiaonan in the hatch raised his head and glanced out, and said firmly: "Impossible." ”

"Are you so sure? But it's been so long....."

Before I could say anything, I was interrupted by this girl: "I said that impossible is impossible, according to the last signal positioning of the ship before the disappearance and the flow calculation of the ocean current, this is it." Besides..."

Speaking of this, the girl suddenly fell silent, and this abrupt half-cut sentence made me very uncomfortable, and she turned her head and said, "What's more? I said, can you finish all at once? This big gasp is suffocating my ........"

Li Xiaonan in the cabin just glanced at me lightly, hid his body tightly behind the cabin door, and said, "You don't understand what I said." ”

"..........." I was very angry: "You say come and listen, maybe I understand?" ”

Clinker, this girl glanced at me, stomped her little feet and said in a trembling voice: "That scientific research ship carries a radioactive isotope, which is non-toxic and harmless, even if the ship is deposited underwater for decades or even hundreds of years, it will not fail, as long as you carry the corresponding detection equipment, you can find it." Do you understand? Know what a radioisotope is? Li Xiaonan stomped his feet and cast a contemptuous look at me.

"No... I don't understand..."

"Well-behaved, it's not scary to be uneducated, read more books"

For the first time, I found out that this girl still has this black belly, what's wrong with no culture, and I didn't take a dime of her food stamps, and I didn't eat an extra grain of her rice. At this moment, the corner of my eye seemed to catch a glimpse of something, and I suddenly turned my head to look into the vast fog on the left.

ps: cough cough cough, how many friends are lazy at home, raise their claws!
