"Ballast iron? What is Ballast Iron? Yuri was confused in the microphone on the other end of the missile boat. Pen, fun, and www.biquge.info

"Go to the front of Mir-2, and the round weights on those suction cups are ballast irons." Jiang Zhiyong had worked on the Jiaolong after all, and he knew everything about the Peace series of deep submersibles with similar structures.

Paustovsky and Anatoly climbed to the stern of the missile boat, lowered the lifeboat and rowed towards Mir-2, the two people leaned the lifeboat under the round-nosed console of Mir-2, and under the waterline were ballast irons of all sizes, Yuri took Ganoviv and others to come over to help, and after working for a while, they finally dragged these ballast irons to Mir-3 with cables.

In the cabin of Heping 3, Jiang Zhiyong skillfully tested the control buttons one by one, "Damn, the grab is out of order!" He pressed one of the buttons repeatedly and said in frustration, and Nepomoche comforted him, "Isn't everything else good, there is no shortage of this." ”

Jiang Zhiyong seemed to remember something, he pressed a green button, "Why is the electromagnetic chuck not responding?" ”

"What is an electromagnetic chuck?" Nepomoche asked.

"Look." Through the front window camera, Jiang Zhiyong pointed to Yuri and others who were busy working, "These ballast iron blocks they moved were fixed in front of us by electromagnetic chucks, and when we dived to the bottom of the lake, we needed to cut off the electromagnetic chucks to release the ballast iron to float." ”

Jiang Zhiyong slapped the green button twice vigorously, "But now I can't release it!" ”

Nepomoche said, "It's good that we found out about this problem, otherwise we would have been buried at the bottom of the lake forever!" ”

"What then?" Jiang Zhiyong was still fiddling with the console.

"Let me go outside!" It was Liu Weiping who volunteered, "I went outside to manually release these ballast irons, and they can also be used as mechanical grabs!" ”

Nepomoche and Jiang Zhiyong glanced at each other and nodded in unison, "It seems that it can only be like this, fortunately you are a Homo sapiens!" ”

In this way, Liu Weiping climbed to the outside of Heping 3 again, Yuri and others were still loading ballast iron for Heping 3, Liu Weiping leaned on the platform, he held the mechanical grab in his hand, and his body slowly entered the lake, and the waterline of Heping 3 became deeper and deeper, and after a while, the lake flooded the top, Jiang Zhiyong pushed the accelerator, and the Stirling thruster slowly pushed Heping 3 away from the dock.

Yuri and the others returned to the missile boat, and followed the track of the Peace-3 in the southeast direction, and he kept sending navigation signals to Jiang Zhiyong, "The Peace-3 reports the depth." ”

"I've dived to 20 meters and everything is normal!"

"Okay, keep heading 125 and keep going!"

Liu Weiping stood outside the cabin, he looked at the surrounding landscape curiously, he had long heard that the water of Lake Baikal is clear and transparent, and it is a rare tourist attraction as far as you can see at a glance. But now that the pressure sensor on his body told him that he had just driven 20 meters underwater, the natural light was already very faint, and the Peace-3 turned on its headlights early.

The two cones of light shone out dense filamentous algae, which were thin and long floating in the water, like hair blowing towards Liu Weiping, "Fortunately, it is a water jet, otherwise it would be strange that Heping 3 would not be entangled." Liu Weiping thought as he reached out to remove the filamentous algae that blocked his view.

"Report, it's 40 meters, avoid the algae zone, and start to accelerate the dive." As soon as Jiang Zhiyong's right foot stepped on the horizontal rudder, Liu Weiping felt his body lean forward slightly, and the Mir-3 pressed down the bow of the ship and slid towards the center of Lake Baikal.

A large salmon more than a meter long surrounded curiously, they did not seem to be afraid of the artificial monster of Heping No. 3, and the salmon swam around against Liu Weiping's face, making Liu Weiping think that he was already in the Dragon Palace.

Suddenly, the salmon fluttered and fled in a panic towards the back of Heping III. Liu Weiping looked through the lake, and saw where the light cone of Heping No. 3 was illuminated, a round face with bulging cheeks rushed over violently, the round face was also full of beards, behind the beard was a round and fat body, the belly was as bulging as the face, two short fins dangled around, and the body was squirming rapidly in the water, pushing the round face towards Liu Weiping.

"Seals!" Liu Weiping recognized these large underwater mammals at first sight, and it turned out that there were seals in freshwater lakes like Lake Baikal.

"Oh no, there's a seal rushing over!" Jiang Zhiyong in the cabin also saw clearly, thousands of seals rushed towards the Peace-3! The seals, like the salmon, scattered in a procession, and as if frightened, they scrambled to swim forward.

"Everyone, grasp it, we're going to dive urgently!" Jiang Zhiyong shouted, he stepped on the horizontal rudder with his right foot to the end, Liu Weiping suddenly felt that he was being clung to the round nose of Heping 3 with a strong force, and a swarm of seals swept over his head and quickly disappeared into the dark lake.

"Report 200 meters, heading 125!"

"Report 400 meters, course is normal!"

"Report 800 meters! The dive is so fast, I'm steady! ”

In Yuri's sonar was Jiang Zhiyong's anxious voice, and Yuri also felt that such a diving speed was too incredible.

In the cabin of the Mir-3, Nepomoche noticed another strange phenomenon, "Captain Jiang, look, there are bubbles underneath!" ”

As soon as Nepo Moche pointed to the screen, he saw that around Liu Weiping, bubbles were floating upwards one after another, more and more, gradually surrounding Liu Weiping. ”

Jiang Zhiyong didn't answer, he frowned, he replaced his left foot and stepped on the horizontal rudder, and the engine had been put into reverse gear in his hand, trying to control the momentum of the rapid dive of Heping III.

Seeing that Jiang Zhiyong had no time to pay attention to himself, Nepo Moche spoke to Liu Weiping outside the cabin through sonar, "Professor, what's going on with those bubbles outside?" ”

"I've noticed, I'm trying to figure out how to measure!"

"Measure?"

"Yes, measure!"

Seeing Liu Weiping turn his head, he faced the smooth bow of the Heping 3 and shot a bright light from his right eye, and the faint reflection penetrated the bubbles in the water and shot into his left eye, "Report, it's methane, it's methane at the bottom of the lake, we may be about to hit the bottom!" Do you want to get rid of the ballast iron? ”

"Okay, I agree!" Jiang Zhiyong immediately responded.

"No, you can explore right away when you get to the bottom of the lake! Isn't that our mission? Nepomoche loudly organized Jiang Zhiyong's opinion.

At this time, the methane outside is even denser, and the entire Peace 3 is already shrouded in a world of bubbles. "Major, the buoyancy here is too small, and we can sink into the silt at the bottom of the lake at any time if we don't shake off the ballast iron!" Jiang Zhiyong was so anxious that he tried to control Mir 3 and convince Nepomoche.
