Otherworld Bone Dragon Operation Guide

Chapter 311 Missile Modification
The waters near Tahiti, about 5,000 kilometers east of the Solomon Islands in the Pacific Ocean.

The container ship "Ocean Express" is speeding across the sea.

The weather was clear, the sea conditions were good, and visibility was excellent. Inside the bridge, the VHF radio suddenly received a communication call.

"Ocean Express, this is Yinmahu Express, calling. Over."

The second mate on duty immediately picked up the microphone and replied, "This is Ocean Express, please go ahead. Over."

"Ocean Express, I am located approximately 2.5 nautical miles behind you, with a bearing of 005 degrees. My current heading is 085 degrees and my speed is 28 knots. I request to overtake you from your port side. Over."

"Yinmahu, understood. My course is 085 degrees, speed 23 knots. I agree to your overtaking maneuver on my port side. I suggest maintaining a safe lateral distance of at least 1 nautical mile. Over."

"Received, Ocean Express. Thank you very much for your cooperation. The entire overtaking process is expected to take 1 hour and 20 minutes. Over."

"Yinmahu, agreement confirmed. Best wishes for a safe voyage. Ocean Express will be listening on Channel 16. Over."

Thank you! Have a pleasant voyage. Out.

The second mate put down the microphone.

When a ship is sailing, doubling its speed will increase fuel consumption per unit distance by about four times. Therefore, the speed of a cargo ship is often not related to its performance, but rather depends more on the shipowner's financial strength—or, in other words, the urgency of the cargo on board.

As a container ship, the "Ocean Express" carries cargo that needs to call at multiple ports on time for transshipment. Therefore, it has always been one of the fastest ships on this route.

It almost always overtakes other ships, and rarely is it overtaken by other ships.

The second mate looked curiously at the electronic nautical chart, found the AIS (Automatic Identification System) information of the "Yinmahu" ship, and then widened his eyes in surprise.

He immediately picked up the intercom, "Old Wang! Quickly check the stern! We're being overtaken by a semi-submersible!"

"I don't believe you for a second!" Elder Wang, the sailor, laughed and cursed on the other end of the phone.

If the "Ocean Express" is a fast train on the sea, then the heavy-duty semi-submersible vessel designed to tow drilling platforms or other ships is simply a tractor on the sea!
So you got overtaken by a tractor? Are you kidding me!
"Hurry up!" the second mate urged. "I'm not kidding you!"

The boatswain, who was called Old Wang, was skeptical, but picked up his binoculars and looked towards the stern of the ship.

In the field of vision, a typical semi-submersible vessel is clearly visible, with cargo obviously loaded on its main deck; another vessel has an unusual shape, but its model is difficult to identify from the current angle.

"Holy crap! It really is!" the boatswain blurted out.

The news spread quickly, and the crew members flocked to the bridge to see what was happening.

The semi-submersible vessel, flying a red flag with yellow stripes, was getting closer and closer, about to overtake the "Ocean Express" from its port side.

The second mate radioed an acquaintance on the "Peace Bridge" ship ahead, but the acquaintance didn't believe him at all.

“Believe it or not,” the second mate replied, “tomorrow it will be your turn to be overtaken by it.”

As the "Yinmahu" sailed to the side, the crew of the "Ocean Express" finally saw clearly that on the main deck of this semi-submersible vessel was actually a tall and majestic sailboat!

The captain, who had rushed to the bridge upon hearing the news, gasped in shock upon seeing the ship: "'Esmeralda'! Who brought out this 'old man'!"

The Esmeralda, with a displacement of approximately 3700 tons, boasts four towering masts and can hoist up to 29 sails. Belonging to the Chilean Navy, it is the world's largest sailing training ship and the only large conventional sailing vessel still in service.

"Why are they rushing off to such an inconvenient destination?" The second mate wondered to himself, watching the "Yinmahu" speeding across the sea at full speed despite its astonishing fuel consumption.

The "Ping An Qiao" ship ahead also suddenly received VHF communication.

"Attention Ping An Bridge. The waters near 17°32′S, 149°34′W have been designated as a temporary no-navigation zone from today until 0600 tomorrow. Please leave this area immediately. Repeat, please leave this area immediately. Over."

"Ping An Qiao received, over."

"Thank you for your understanding and cooperation. Please be aware of navigational safety. Call ended."

The duty officer on the "Ping An Qiao" put down the intercom, equally puzzled—why was a no-navigation zone suddenly established?

He picked up his binoculars and quickly spotted a large, oddly shaped ship in his field of vision, his mouth agape in astonishment.

“Ocean Express, navigation is prohibited on the left side ahead! And I also spotted a 'street thug'!” He immediately contacted the second mate of the Ocean Express via radio.

"What 'street thug'?" The second mate didn't understand at first.

“The one that ‘tops nine balls’!” the duty officer added eagerly.

"Neptune?! You're kidding me!" The second mate didn't believe it at all. "Tch, believe it or not! We need to start avoiding the no-fly zone now."

The minor incidents encountered by these cargo ships did not affect the progress of the electronic reconnaissance ships, nicknamed "street thugs," in carrying out their missions.

Four hours later, the "Yinmahu" arrived at the designated sea area on time and immediately began its diving operation. As the huge hull slowly sank into the water, the sailboat "Esmeralda" carried on its main deck gradually floated up.

In addition, it also carries a sailboat with a fiberglass hull, only much smaller in size.

The radar reflectors on the masts of the two sailboats had long been removed, and all exposed electronic equipment and metal parts had been completely removed or tightly covered.

Soon, the two sailboats, one large and one small, were fully released onto the open sea. The semi-submersible vessel "Yinmahu," having completed its mission, quickly sailed away from the scene.

"Begin testing, starting with X-band radar scanning, detection range 250 kilometers," the commander ordered.

Modern radar locates objects by receiving electromagnetic waves reflected from them. Metal hulls are excellent reflectors of electromagnetic waves, but fiberglass hulls absorb or scatter most of the signals.

The all-wooden warships in this other world would also face similar problems.

Soon, after filtering the metal hull of the Esmeralda using algorithms, the radar detection results were extremely poor.

"This RCS (radar cross section) value is even less than that of a small seagull!" the technician reported helplessly, looking at the data.

Although the metal masts, rigging, and spars of a sailboat are reflectors, they are so narrow that they can only produce extremely weak and intermittent echoes, which appear as background noise on a radar screen.

Moreover, the otherworldly Su Ming is about to face a world without even these metals.

When the sails are fully deployed, the radar reflection effect is slightly better, but the sails themselves are made of thin material, and the resulting echo signal is still very weak.

These characteristics are extremely unfriendly to high-frequency precision radar! In fact, many signal features are treated as noise and removed in conventional software processing!
"Fortunately, this long-distance detection simulation test was conducted." An engineer sighed with lingering fear as he looked at the dismal performance.

However, radar signals are only part of the problem.

All guidance and control systems of modern anti-ship missiles are designed for the structural characteristics of modern steel behemoths with high radar cross-sections (RCS), and military engineers have never considered using them to attack wooden sailboats.

This was originally a matter of course, but the appearance of Su Ming, this anomaly, turned what was originally a topic that did not need to be considered into an urgent problem that needed to be solved.

Therefore, they almost forced themselves to buy this antique training sailboat. Their purpose was to use various modern radar systems to conduct actual detection on it, obtain the most accurate low-RCS target data, and quickly optimize and adjust the guidance software of the "Eagle Chicken" missile.

Beside them, a Jiangkai II-class guided-missile frigate with its AIS signal not activated was accompanying the operation.

Inside the ship's vertical launch system, eight missiles awaiting testing lay silently. Data cables connected to the maintenance interface indicated that staff were urgently rewriting the radar firmware based on data from the electronic reconnaissance ship.

After the radar system passes inspection, the next phase will be their test firing of the missile. Weapons can only be truly tested and proven effective by actually flying them in the air.

All the test personnel felt immense pressure; time was extremely tight, and they had to race against the clock!

In another world, in the waters where the Light Fleet is located, underwater, eight hours ago.

Amidst the chaos, a faint mechanical hum, almost imperceptible to any living being, echoed from within the metal wreckage. After suffering a devastating attack and having all its main functions paralyzed, the emergency backup computer deep inside the "Heat-Reducing Bolt No. 1" torpedo was forcibly activated.

Start
The self-test of the No. 1 attack torpedo, which is designed to de-escalate heat, has begun.
The current anomaly information is as follows: Thruster assembly failure; Main control computer failure; Fiber optic signal loss; Main power supply failure; Depth sensor failure; Sonar failure.

Radio emergency system activated, monitoring initiated.
Listen for 30 seconds. No response signal, no control signal recorded.

Current mission mode: Loyal; Confirmed status: Mission out of contact; Warhead self-destruct sequence initiated, countdown 3 seconds.

$>321 Fever-reducing suppository No. 1 exits the task sequence.

Wishing you continued good news and a sunny journey home!

Inside the slowly sinking, broken metal cylinder, alchemical explosives were instantly ignited. In the silence, a burst of intense light suddenly erupted, only to be abruptly extinguished by the surrounding seawater, leaving behind only a fleeting, dim flash.

The surrounding Naga warriors didn't even have time to sense any sound or vibration before the deadly explosive energy engulfed them!

Ultra-high pressure cavitation expands rapidly in the deep sea, then collapses violently due to immense water pressure. A devastating shockwave sweeps across the area at speeds invisible to the naked eye.

The Naga warriors on the scene had no time to react. Their strong bodies shuddered violently as if struck by an invisible hammer, and they spewed out mouthfuls of dark green blood mist.

Many of the Naga were frozen in place, floating silently in the cold sea.
