Eunuch, do you really know these martial arts?

"The test is divided into three stages," Yang Zhan's voice came through the speakers in the training room.

"In the first stage, Master Qin will gradually increase the intensity of the simulated signal. You need to report your physical sensations and try to maintain the stability of the five internal organs."

"Then you will engage in strenuous exercise inside the pressure chamber while being subjected to signal interference."

"The third stage..."

Yang Zhan paused for a moment, then said, "Emergency situation simulation. Specific details are confidential."

The pressure chamber has a small interior space, about three meters in diameter, and its four walls are made of smooth alloy.

"Communication test." Old Qin's voice rang in my ears.

“Clear,” Jiang Nian replied.

"Vital signs are normal." Dr. Xu's voice came from another channel. "Consultant Jiang, report any discomfort immediately."

"clear."

The cabin lights were adjusted to a soft white.

"Phase one, begin," Yang Zhan ordered.

At first, I didn't feel anything.

Then a faint resonance came from the liver area.

"I'm starting to feel it."

"strength?"

"It's very low, about five percent."

"What is the reaction of the marked node?"

"The liver node showed a slight response, while other nodes remained stable."

Old Qin recorded the data: "Jiang Nian, try using the breathing technique I taught you yesterday to guide him."

Jiang Nian took a deep breath, and as his breathing rhythm changed, the pulsation of his liver nodes began to adjust, gradually synchronizing with his breathing.

"The synchronization rate has decreased," Qin Lao reported. "The guidance has been effective."

"Increase signal strength."

The sense of resonance is enhanced.

This time, not only the liver, but other nodes also began to respond.

Five channels were established simultaneously, and the energy of the marked nodes was distributed and extracted.

"The synchronization rate has stabilized at 16% and is no longer rising!"

Old Qin exclaimed excitedly, "The energy diversion is effective!"

Yang Zhan nodded at the observation window: "Phase one passed. Prepare for phase two."

The environment inside the pressure chamber began to change.

Gravity sensor activation simulates pressure at a depth of 30 meters underwater.

At the same time, several grips and foot pedals popped out from the bulkhead.

"Moderate-intensity aerobic exercise," Yang Zhan instructed. "Twenty pull-ups per minute, combined with forty squats, for ten minutes. Qin Lao, maintain level three interference intensity."

"clear."

Jiang Nian stood up and grabbed the handle above her head.

The spleen node suddenly twitched halfway through the movement!
"Uh!"

He groaned and almost dropped his hand.

"What's wrong?" Dr. Xu asked anxiously.

“The sports meet disrupted the rhythm of the events,” Jiang Nian said through gritted teeth. “They are readjusting.”

"This is normal."

Qin Lao quickly analyzed the data, "When you exercise, your blood and qi surge, and your joints will instinctively accelerate their response. Jiang Nian, adjust your breathing rhythm so that your joints adapt to your exercise frequency."

After three pull-ups, the spleen nodes gradually stabilized.

But when squatting, the kidney nodes start to become agitated again.

"The kidneys govern the bones. Squats put a lot of pressure on the bones, and the kidney nodes react strongly," Qin Lao explained. "We try to direct some of the energy to the bones."

Jiang Nian did as instructed.

Internal energy seeped into the bone marrow, and the energy from the kidney nodes was guided to the legs.

Squats became easier.

"Smart!" Yang Zhan praised, "You've learned and applied it effectively."

Ten minutes passed.

Jiang Nian was soaked in sweat, but he didn't stop moving.

"Heart rate 140, blood pressure normal, blood oxygen saturation 98 percent," Dr. Xu reported. "Physiological indicators are good."

"Synchronization rate?" Yang Zhan asked.

"The fluctuations are between 14% and 19%, with an average of 16.5%," said Mr. Qin. "It's slightly higher than the static state, but still within a controllable range."

"Phase two passed." Yang Zhan glanced at the time. "Take a three-minute break and prepare for phase three."

Inside the pressure chamber, Jiang Nian loosened his grip on the handle and gasped for breath.

"How are you feeling?" Old Qin asked.

"It's harder than I imagined." Jiang Nian wiped his sweat. "With movement and distractions happening at the same time, it's hard to concentrate completely."

"That's how it is in real combat," Yang Zhan said. "The enemy won't wait for you to be ready before they make their move. The third phase will be even more difficult, so be prepared."

Three minutes passed quickly.

"Phase three, begin."

The cabin lights suddenly went out!

Immediately afterwards, a piercing noise came from all directions!
It's not a single frequency, but a mixture of dozens of different tones and rhythms.

Sharp, hoarse, and low-pitched, with no discernible pattern.

"Audio jamming!" Old Qin shouted. "The organization may be using sonic weapons!"

Jiang Nian covered her ears, but the noise penetrated her skull and echoed in her brain.

The pulsation of the five internal organs became instantly disordered!
"The synchronization rate has soared to 25 percent!" the operator exclaimed.

"Jiang Nian! Calm your mind!" Yang Zhan shouted.

How to stabilize it?
The noise felt like countless needles piercing my brain, turning my thoughts into a jumbled mess.

The energy from the marked nodes surged wildly through the body, making the meridians feel like they were about to burst.

"We can't act rashly..."

Jiang Nian bit her tongue, and the sharp pain brought her back to consciousness for a moment.

"The synchronization rate is declining!" Old Qin exclaimed incredulously.

The noise lasted for thirty seconds, then suddenly stopped.

The lights come back on.

Jiang Nian knelt on one knee, panting heavily, with blood seeping from the corner of his mouth.

"Phase Three is over."

Yang Zhan's voice came through, "Test complete."

The hatch opens.

The medical team rushed in and helped Jiang Nian onto a stretcher.

"Mild concussion, eardrum damage, and minor internal bleeding," Dr. Xu quickly examined the patient. "Immediate treatment is required."

"Wait a minute." Jiang Nian pushed open his oxygen mask and looked at Yang Zhan and Old Qin who had walked in. "What was the result?"

Old Qin looked at the tablet in his hand and remained silent for a few seconds.

"The theoretical safety line is 20%. You've met the standard."

"Just meeting the standard?" Yang Zhan frowned.

"Considering that the test intensity far exceeded the expected actual interference, this result is already very good."

Bai Yongxu's image then appeared on the large screen in the training room.

“I watched the entire test.”

The commander's expression was serious. "Jiang Nian, are you sure you can carry out the mission in three days?"

Jiang Nian sat up on the stretcher: "I'm sure."

"But your body—"

“The injury can be healed,” Jiang Nian interrupted. “We only have one chance. The South China Sea won’t wait for us.”

Bai Yongxu looked at him silently.

After a long silence, he slowly nodded.

"Alright. Chief Zhao, initiate the action plan. Elder Qin, provide full assistance to Jiang Nian's recovery. Yang Zhan, formulate a detailed tactical plan."

...Medical center, special ward.

Jiang Nian lay on the bed, with seven or eight monitoring devices attached to her body.

Su Qing was recording data on the side, her eyes red.

“Teacher Jiang, you really scared me to death just now,” she said softly. “Dr. Xu said that if the noise had lasted for another ten seconds, you might have suffered permanent hearing damage.”

"It hasn't even been ten seconds yet." Jiang Nian smiled, but the movement pulled at the wound on the corner of his mouth, causing him to wince in pain.

The door was pushed open, and Yang Zhan and Old Qin walked in together.

"How are you feeling?" Old Qin asked.

"I won't die." Jiang Nian tried to sit up, but Yang Zhan held him down.

"Talk to me while lying down." The old instructor pulled up a chair and sat down. "The test exposed a few problems that need to be addressed."

"what is the problem?"

“Your method of dealing with sudden disruptions is too risky,” Yang Zhan said bluntly. “Using chaos to quell chaos is genius if it succeeds, but suicide if it fails. We need a more reliable solution.”

Old Qin chimed in, "Your internal energy is being depleted too quickly. You won't be able to sustain it in a prolonged battle."

Jiang Nian remained silent.

He knew the two of them were right.

"So? Is there a solution?"

“Yes.” Yang Zhan pulled out a thin manual from his pocket. “It was originally for regulating internal energy, but I modified it. Combined with your marking system, it should improve energy utilization efficiency.”

Jiang Nian took the manual.

The paper is yellowed, and the ink is handwritten in traditional Chinese characters, accompanied by a simple diagram of human meridians.

"The five elements generate each other in an endless cycle."

Yang Zhan pointed to the first page, "Previously, you were guiding the energy of the five internal organs separately, each fighting its own battle. Try connecting them to form a closed loop."

Old Qin's eyes lit up. "That's right! If we can make the energy of the marked nodes flow naturally in this order, we won't need you to guide it all the time!"

"That's how it is in theory," Yang Zhan said, "but it's very difficult to practice in practice. The nodes of the five internal organs are not meridians or acupoints, so the control precision required is extremely high."

"How long will it take to learn?" Jiang Nian asked.

"It depends on your comprehension." Yang Zhan looked at him. "It took me three months to figure it out back then. You... three days, I guess."

"Three days?" Su Qing exclaimed in surprise, "How is that possible?"

"Even the impossible must become possible." Jiang Nian opened the manual. "Let's begin."

For the next 72 hours, Jiang Nian entered a state of frantic studying.

Every morning at five o'clock, Yang Zhan would arrive at the ward on time to instruct patients on the mental techniques of the Five Elements Cycle.

In the morning, under the monitoring of Professor Qin's team, adaptive training was conducted to test the impact of different guidance methods on the marking system.

In the afternoon, I underwent intensive treatment at the medical center to repair the damage caused by the test.

In the evening, I continued studying the manual and practicing meditation.

……

three days later.

"Time is up."

Yang Zhan pushed open the door and came in, holding his combat uniform.

"Operation meeting in one hour. Then we'll depart."

The large screen displays a real-time nautical chart of the South China Sea.

"The vessel consists of a medium-sized transport vehicle and three escort vehicles and is expected to pass through the Yingzui waters at 2 p.m. today."

He circled a location: "The water here is 800 meters deep, and the currents are complex, making it suitable for an ambush."

"Guard configuration?" Yang Zhan asked.

"Two patrol vessels, similar to the ones Jiang Nian encountered before. One attack vessel, equipped with a high-energy particle cannon." Chief Zhao zoomed in on the image. "The attack vehicle is new; we haven't seen it before."

"Our side has deployed six members of the Sea Dragon Squadron, equipped with the latest type of individual underwater vehicle, carrying absorbent mines and acoustic chaff."

"Advisor Jiang will be in charge of the main attack, traveling in a modified fast underwater vehicle. In addition, the South China Sea Fleet will send an attack submarine to provide support from the perimeter, but will not participate in the operation directly to avoid exposure."

Bai Yongxu looked at Jiang Nian: "Is your mission clear?"

“Understood.” Jiang Nian nodded. “Raid the transport vehicle, subdue the crew, and take control of the cockpit. Then, feign normal navigation and buy at least six hours for the Hailong Squad to transfer the ore ingots to our rendezvous point.”

“Remember,” Yang Zhan interjected, “your primary objective is to control the vehicle, not to kill people. After subduing the crew, replace them with the false identities we’ve prepared and continue sailing.”

"The organization has dozens of transport ships traveling back and forth every day, so it won't be noticed in a short period of time."

Old Qin handed Jiang Nian a small device: "This is a signal simulator that can replicate the transport ship's identification code and communication characteristics. Once activated, the base will consider the ship to be in normal working order."

Bai Yongxu stood up and looked around at everyone.

"This operation is extremely risky. But if successful, we will not only obtain a large number of marrow ore samples, but also intelligence on the organization's transportation network, and may even obtain the access code to the South China Sea base."

He looked at Jiang Nian: "Finally, are you ready?"

Jiang Nianli stood at attention: "Ready."

"Okay." Bai Yongxu saluted. "I wish you success."

……

The base's underwater dock.

Jiang Nian was already dressed.

The specially designed deep-sea combat suit has an upgraded built-in jammer that can simultaneously shield against signal interference and sonar detection.

Yang Zhan then helped him adjust his helmet.

Qin Lao said in the communication channel, "Remember, once the synchronization rate exceeds 25%, immediately activate the strong interference mode."

"clear."

"The Sea Dragon Squad is in position."

Commander Zhao's voice came through, "The deployment in the Eagle's Beak sea area is complete, we're just waiting for you."

Jiang Nian walked towards the underwater vehicle at the edge of the dock.

"This Nightshade was specially modified for you." Yang Zhan patted the hull. "It's fast and has good stealth, but its defenses are weak. Don't try to fight it head-on."

"know."

The hatch is closed.

The engine started, and a deep hum came through the bulkhead.

"Advisor Jiang, this is Hailong No. 1."

The captain's voice came through the channel, "We have arrived at the designated position, the underwater minefield has been laid, and the jamming field is being warmed up."

"Received. I will arrive in thirty minutes."

The submersible glided into the water.

Through the porthole, you can see the base lights rapidly receding into the distance, swallowed by the darkness of the deep sea.

The flight path has already been planned on the tactical tablet.

Avoiding major shipping lanes, traversing underwater canyons, and remaining submerged throughout the entire journey, minimizing the possibility of being detected.

Twenty minutes later, the submersible entered the Eagle's Beak waters.

Several green dots appeared on the sonar screen; they were the underwater vehicles of the Sea Dragon Squadron.

"Advisor Jiang, welcome to the hunting grounds."

Hailong-1's voice carried a hint of amusement: "The minefield is located in the southeast, covering a diameter of 500 meters. The jamming field has been activated, capable of blocking conventional sonar detection, but its effectiveness against the organization's advanced equipment is unknown."

"Target location?"

"Breaking news: the Xuanwu No. 7 convoy has just passed the third navigation mark."

Jiang Nian pulled up the radar image.

The six green dots represent the Sea Dragon Squad, scattered around the perimeter of the ambush zone.

A red dot is moving slowly; it's the target fleet.

"The sonar characteristics of the escort vehicle have been analyzed."

Qin Lao transmitted data: "Two patrol vessels, with standard sonar configurations. But the attack vessel... its active sonar pulse is quite unique."

A waveform is displayed on the screen.

“This is…” Jiang Nian frowned.

“Imaging sonar,” Hailong-1 replied. “It can not only detect distances, but also construct three-dimensional images. This thing can see underwater details clearly, greatly reducing the effectiveness of camouflage.”

"Is there a solution?"

"Yes, but the risks are high," Hailong-1 said. "We need to create chaos with flares before it activates its imaging sonar. But the timing has to be precise; too early and we'll alert it, too late and we'll be exposed."

Jiang Nian thought for a few seconds.

"I'll do it." (End of Chapter)
