On the 50,000-ton destroyer, two 15-meter-long rescue boats, lifted directly by robotic arms, are slowly extending towards the sea.

In the first rescue boat, named Poseidon 1, Yuan Yi sat alone at the control panel.

The second Poseidon II had five professional rescue team members on board.

Inside the command tower aboard the aircraft carrier Beijing.

Everyone looked at the large screen in front of them, which was displaying footage from inside the two rescue boats.

"Poseidon 1, your search location is *** East longitude *** North latitude ***".

"Poseidon 1 received."

"Poseidon II, your search location is *** East longitude *** North latitude ***".

"Poseidon II received."

After the two rescue boats were lowered into the sea, the robotic arms slowly released them, and everyone saw the two rescue boats disappear beneath the water.

In the monitoring position nearby, a team composed of the Poseidon development company and professional rescue engineers was constantly typing on the computer.

Suddenly, one of the staff members shouted.

"Poseidon 1, Poseidon 1, you have deviated from your intended course."

"Please immediately repair the preset flight path."

Upon hearing this, everyone looked up at the video feed of the Sea God I on the large screen.

At this moment, a staff member shouted again, "Poseidon 1 is sinking at an abnormally fast speed."

A deep-sea submersible is a device that can conduct exploration and research in the deep-sea environment. Its principles mainly include the following aspects.

Buoyancy adjustment: Deep-sea submersibles adjust their buoyancy to rise or sink.

For example, underwater gliders change buoyancy by altering the volume of seawater they displace, while submersibles change buoyancy by adjusting their own weight (such as by using counterweights and ballast tanks).

Density regulation: Essentially, deep-sea submersibles achieve a balance between buoyancy and gravity by adjusting their own density.

When the oil bladder contracts, the volume of seawater displaced decreases, reducing buoyancy.

When the oil bladder expands, the volume of seawater displaced increases, thus increasing buoyancy.

After the submersible is equipped with counterweights, its mass increases significantly while its volume changes very little, ultimately increasing the density of its overall structure.

Propulsion and Control: Deep-sea submersibles are typically equipped with propulsion and control systems to achieve precise motion control.

For example, underwater gliders change their attitude by moving internal sliders, thereby generating a horizontal force to propel themselves forward.

Pressure-resistant materials: The hull and structure of deep-sea submersibles must be made of high-pressure resistant materials to withstand the enormous pressure of the deep sea.

Energy Management: Deep-sea submersibles require an efficient energy management system to ensure long-term mission execution.

For example, using efficient energy conversion technologies such as fuel cells and solar cells, as well as new energy storage technologies such as lithium-ion batteries and flow batteries.

Navigation and Positioning: The deep-sea submersible is equipped with a high-precision navigation and positioning system, such as Kalman filtering, particle filtering and other algorithms, as well as seabed topography matching navigation technology, to ensure accurate positioning in complex environments.

Sensors and Data Processing: Deep-sea submersibles use a variety of sensors (such as sonar, vision, radar, etc.) to perceive the environment and improve the system's perception and anti-interference capabilities through data fusion technology.

The Poseidon 1, piloted by Yuan Yi, is now a cutting-edge example of advanced technology in the world.

The purpose is to explore the secrets of the deep sea.

After Yuan Yi landed on the sea and received the message that the robotic arm had been retracted, he immediately started adjusting the density chamber.

The submersible begins sucking up seawater directly to achieve a rapid descent.

Even a minute or a second more in the situation could cause the outer shell of the 096B submarine to be squeezed and cracked.

Without the protection of the submarine, the crew inside would be crushed to death by the seawater.

So after he went into the sea, he rushed toward the location he had detected as quickly as possible.

Yuan Yi was extremely annoyed by the chattering sound coming from his headset.

He couldn't tell everyone that he knew where the wrecked submarine was.

So all he could do was tell the system, "Block them out, that's the cause of the signal failure."

"Yes, Master."

The little elf Gou Dan'er took immediate action, blocking all communication signals on Poseidon 1, including radar and sonar.

Instantly, on the large screens relayed aboard the aircraft carrier, the signal from Poseidon 1 disappeared, and the monitoring screen went black.

Yi Feng frowned as he watched Yuan Yi disappear from the big screen.

He turned directly to look at the rescue team.

"What's going on?"

The head of the company that developed Poseidon 1 stood up at this moment.

"Report: The malfunction of Poseidon 1 may have been caused by the rapid descent just now."

"It's also possible that the signal source was directly interfered with by the ocean's magnetic field."

Upon hearing this, Yi Feng's face darkened, and he said, "Contact Shanghai Shen-1 immediately."

"Yes, sir."

The research and development team of engineers immediately began continuous calls and searches for Poseidon 1.

Unfortunately, their methods were still unable to bypass the system's blocking.

Just as they were anxiously calling out to Yuan Yi and watching the descent of Poseidon II.

Yuan Yi had already steered the Poseidon 1 toward the direction of the wrecked submarine.

The 096B nuclear submarine was about thirteen nautical miles away from where he crashed, and he didn't know why it was located where the aircraft carrier was docked.

The submarine, however, sailed more than thirteen nautical miles away. It is possible that after sending out a distress signal and losing contact, it resumed operation on the seabed for a period of time.

What Yuan Yi didn't know was that just as they were taking action...

A hundred nautical miles away from them.

Emily's two Seawolf-class submarines at the Guam base, along with submarines from the Monkey Kingdom, the Cherry Blossom Kingdom, and the South Korean Kingdom, are silently advancing towards the mission area.

They still had reservations about China's large-scale mobilization in this sea area.

They do not believe China's claim that it has no intention of waging war.

They only believe what they can see.

On the aircraft carrier Beijing.

"Report."

The communications soldier shouted loudly.

"The submarine just reported that it has detected an unusual sonar signal."

"Suspected to be an Emilia Seawolf-class submarine, a Monkey U20 submarine, an Osaka Jun super submarine, and a Korean KSS-class III submarine."

Upon hearing the messenger's report, Yi Feng's brows furrowed even more deeply.

He knew that the guys around him wouldn't stay put.

"Warn them that the boundary is one hundred nautical miles."

"Designate a training area. If they try to force their way in, they'll have to bear the consequences!"

"Yes, Captain."

The communications officer quickly relayed the order.

The chart room directly designated a 100-nautical-mile radius around the two carrier battle groups as the exercise area and issued a public announcement.

And it was announced directly on the public channel.
