Otherworld Bone Dragon Operation Guide

Chapter 130 Surprise Attack on Snail Island

Su Ming dropped the towed sonar into the water. If that really was a zombie base, then the remaining octopus sea monsters were most likely in the vicinity.

Sure enough, half an hour later, the sonar detected three large underwater targets about 30 kilometers from Snail Island. They appeared to be in a dormant state, clustered together and suspended in the deep sea at a depth of about 600 meters.

“It’s an old friend of ours!” Su Ming quickly confirmed using sonar data.

Last time they encountered these three sea monsters, they thought they were controlled by three necromancers, but it turned out that it was controlled by the Saint-level Yesia alone. Fortunately, Ice Maiden Yesia was confirmed to be absent this time, otherwise Su Ming would almost have developed PTSD.

Su Ming slightly turned the white triangle, pointing it at the target.

"We'll fly over the sea monster and drop bombs." He quickly marked it on the sand table. "If we succeed, we'll launch a surprise attack on Snail Island!"

"Ok!"

The zombies on the White Triangle were activated, and they brought out the alchemical explosive barrels from the ship's hold. Violet and Su Ming installed and adjusted the fuses one by one. These fuses were equipped with mechanical water pressure gauges that Su Ming had bought on Earth.

The second plan Su Ming proposed to eliminate the sea monster—depth charges—was finally implemented today.

As they closed the distance, the active sonar mode was able to directly acquire the target. Beianchi quickly calculated the speed and trajectory, "Ten seconds to prepare."

The zombie gang rolled the alchemical explosive barrels to the edge of the deck and, as Beanche's countdown ended, pushed them one by one into the sea. Hundreds of barrels of explosives sank rapidly into the seawater, rising quickly in the air bubbles.

"It will take about two minutes to sink to the predetermined depth," Su Ming said, looking at the sonar.

The winds still howled in the stormy sea area, the sun was close to the sea surface, and dusk was approaching.

"Those collars on those pirates should be about to explode by now," Beanie remarked.

Zi Jin glanced at Su Ming and found that the latter's expression was normal.

Su Ming noticed her gaze. "Don't worry, even if you didn't suggest it, I would have insisted on doing it anyway."

"How am I being uncompassionate?" the girl said with a gentle smile.

"I'm not crazy. Why would I let a criminal go free and allow more innocent people to suffer?" Su Ming replied irritably. "It's a pity that the orc spy got off easy; the collar only destroyed his tail."

The spy, Angelo, would certainly communicate with his accomplices during the day, reporting that everything was as usual. Therefore, maintaining his "normal work" was beneficial in ensuring the surprise of the White Triangle operation.

Changing his collar separately would seem too deliberate; the three of them didn't want to lose their real prey for this small fish.

****
In the sunset over the beach, Angelo, the orc spy mentioned earlier, sat quietly on the shore waiting for the White Triangle, idly fiddling with a string of small balls in his hand. Searching for these balls was easy for him; his team had already dutifully completed the required number.

As for the other three teams, at his suggestion, they completely gave up, which meant that Belladonna's group had to spend an extra day searching the three islands again.

The sea breeze began to cool, and Angelo got up to stretch his legs, which had gone numb from sitting for so long. He stroked his tail; when Belladonna put the collar on him, he had used illusion magic to place his tail on his head, replacing the collar around his neck.

Fortunately, the enemy did not see through his illusion, which was his greatest advantage as the fox clan's best infiltrator.

A loud crash suddenly erupted beside him, the shockwave violently knocking him to the ground. He coughed as he got up, looking blankly to his side. Half his body was covered in blood and tattered fur; several fingers were missing, and his tail was gone too.

The intense tinnitus made him unable to hear anything. He looked up and saw the pirates running around in terror, exploding one after another, their blood spraying onto him.

Angelo suddenly realized that he had been completely tricked. He looked up to the sky and howled, his voice filled with resentment at being manipulated.

****
In the deep sea beneath the White Triangle, the pressure gauge on the alchemical explosive barrel pointed to the predetermined location, and muffled explosions echoed one after another in the deep sea.

The sonar data indicated that all three sea monsters were hit by a massive explosion.

Depth charges don't need to hit the target directly; the high pressure from the seawater will crush their bodies and internal organs. Even zombies, given enough bombs, cannot withstand the impact. The three sea monsters struggled for a while, but eventually their movements ceased, and they continued to sink into the sea.

The three men high-fived in celebration in the driver's seat.

“The enemy will definitely notice something’s wrong with the sea monster. Let’s launch a surprise attack!” Beanie said.

"Ok!"

The White Triangle cut through the white waves, heading towards Snail Island. It arrived just as dusk was falling, the timing perfect.

Night combat may present visual obstacles for the enemy, but it is a complete advantage for them who are equipped with radar and sonar.

Bianchi used a low-light telescope to survey the island. From this distance, she could already see quite a few buildings. Many orcs were frantically running out of them, carrying supplies.

“They probably wanted to board the ship and escape,” she said.

"Clear the building first!" Su Ming said.

"Alright. 3.2 degrees to port, 24.3 degrees elevation, one incendiary shell!" Beanche quickly announced the firing angle, and the MK71 heavy gun then opened fire.

At a distance of 13 kilometers, the shell would take about 30 seconds to fly. The girl held up her binoculars and kept observing until a wisp of fire rose into her field of vision.

Beanie quickly adjusted her firing parameters and began rapid fire. In just two minutes, the island facing them was engulfed in flames. The strong winds in the stormy sea intensified the fire. The island's vegetation was also ignited, spreading rapidly in all directions and to the other side.

The orcs panicked even more. They abandoned their supplies, quickly climbed onto the ship, and hastily set sail.

With a favorable wind and strong winds, coupled with magical propulsion, the orc transport ship quickly increased its speed to 18 knots and fled westward towards Ling Island.

This location was 80 kilometers from the main island of Ling Island. Su Ming calculated it and decided to let them run a little longer. The White Triangle leisurely circled Snail Island, executing those who hadn't had time to board one by one before starting to pursue at a speed of twenty-five knots.

To prevent any from escaping, they left hundreds of zombies on the island before leaving.

The steamship's high speed, ignoring wind direction, gave it a ridiculously high advantage over the sailing ship. Twenty minutes later, the White Triangle easily maintained a 15-kilometer distance, angled and parallel to its opponent. The White Triangle held the windward position, allowing its cannonballs to be fired with the wind at its back. If the enemy's mages wanted to attack, they would have to fly over against a Force 7 headwind. From this position, they couldn't reach Ling Island forward, nor could they retreat back to Snail Island.

Su Ming was confident he could kite his opponent to death!
“Fifteen kilometers is a bit far; the hit rate will be much lower,” said Beianqi. “Can’t we get closer?”

"We have plenty of shells, safety first," Su Ming said. "Laser ranging: 15.32 kilometers!"

Beanie nodded. The opponent might possess the combat power of a Grand Magister; it would just mean consuming more ammunition, so she'd save herself the trouble if possible.

She repeated the previous procedure: first, she would test fire one shot, correct the trajectory, and then fire several more in rapid succession. Then she would observe the point of impact, repeating this cycle. The powerful balancing ability of the anti-roll device significantly reduced the swaying of the white triangle. Even in these sea conditions, the MK71 could achieve high accuracy at such a long distance.

Although the second round of rapid fire missed, it resulted in a cross-shot, marking the first time that Beanie had launched an effective attack at this distance, and her inner shock was palpable.

"I'm going to be spoiled rotten by you all!" she lamented.

A shell finally hit its target; a sharp white flash streaked through the night as the shell shattered in mid-air.

All three of them wore expressions of astonishment.

"Saint-level?" Su Ming murmured.

“Saint-level.” Zi Jin’s eyes narrowed slightly as she confirmed.

The MK71's shell has a muzzle velocity of Mach 2.2, and even after traveling 15 kilometers, its speed would still be at least half of its original velocity. A single metal shell weighs 117 kilograms; only a Saint-level warrior could intercept such a projectile!
"This fluctuation is Bing Shuyeshia!" Beianqi had also fought her at close range, so she recognized her. She said incredulously, "But wasn't she still at Lingbei Port this morning!"

Su Ming quickly increased the radar's rotation frequency and switched to short-range air-to-air mode. The Holy Demon Swordsman's flight speed was far superior to that of a Grand Magister!

Fortunately, the radar was clear, and Bing Shu did not launch a surprise attack, which relieved him.

"Has your intelligence network been infiltrated?" Violet asked Beianqi. At the same time, she also cast several detection spells to confirm that the area within a one-kilometer radius of the White Triangle was still safe.

“Unlikely—I’ll investigate later!” Beanie said. She fired a volley of shells, this time hitting two targets, which were also intercepted by Yesia.

Su Ming quickly reviewed the battle situation. From dropping depth charges on the three giant octopuses to shelling Snail Island, the White Triangle took half an hour to travel. As the controller of the sea monsters, Yesia would have noticed immediately, but she chose to use this time to transfer supplies and evacuate from Snail Island by ship.

The Orcs' subsequent disarray was likely due to their misjudgment of the White Triangle's speed at full power and the Mk71 cannon's range.

Therefore, it can be inferred that Yesia never intended to engage in battle with the White Triangle!
"If we get within ten kilometers, how much can you improve your shelling accuracy?" Su Ming asked Bei Anqi.

"Still getting closer?" The girl's eyes widened. "Aren't we going to escape?"

“We won’t run away,” Zi Jin replied firmly. She had figured out the crux of the matter. “Bing Shu is definitely not in good condition, otherwise she would have made her move long ago. Taking advantage of her weakness is the best strategy!”

Beian still felt it was too risky. She pressed her hand to her chest. "I am willing to avenge my comrades on the Five Fangs and I am not afraid to fight to the death—but the opponent is, after all, a Saint-level being!"

“It’s precisely because she’s a Saint-level being that we can’t let her go,” Zi Jin said. “We’ve already offended her terribly. If we don’t seize this opportunity today, we’ll only face greater danger in the future!”

Offending a Saint-level being is troublesome. Beanche asked the crucial question, "Then how do we kill her? We can't hit her with artillery anymore, not even with the Mk71!"

There's no room for complacency on this issue; we can't afford to be complacent. After their last battle, Su Ming and the other two conducted extensive post-battle analysis and targeted reflection, and their opponents will likely do the same. In this world of life-or-death struggles, those who don't take battle seriously have already been ruthlessly eliminated.

Those who are perfunctory have no right to survive on the battlefield!
Although Yesia is not known for her defensive abilities, the difference in their levels still makes it difficult for them to inflict sufficiently fatal damage on her.

“My attack power is barely enough,” Violet said. “Although I haven’t been able to fully complete the domain ‘Natural Rhythm’ yet, I’ve already been able to advance beyond my current level to a certain extent.”

“That’s right, you have the divinely bestowed scepter.” Beanie clapped her fists together. “That’s a weapon given by the gods!”

Zijin shook her head. "The Divine Blessing Scepter can't kill people. During the Battle of Agate, I shaved the Fusang ship bald and not a single person died; during the Battle of Wheat, I used Yangyan to attack a pirate, and when that pirate was pulled out of the sea, he was still alive, and there was even some magic protecting him."

This was the first time Beanie had ever heard of such a thing: a divine warrior who couldn't kill?

"Legend has it that weapons favored by the gods are a sign of divine mercy towards humanity," Su Ming said. "The fact that they don't involve killing makes sense—does that mean even the six-pointed star can't be used?"

Violet pulled the bone staff from her head, unfolded it, and the Staff of Doom appeared in her hand, emitting a ghostly light.

“I’ve modified it a bit recently,” she explained to the two. “I have a move called ‘Shadow End’ that can kill Yesia, but you have to destroy her defenses first.”

"The Anzio anti-materiel sniper rifle can also provide damage if the opportunity arises," Su Ming added.

The three discussed their coordinated plan, during which Beanche maintained suppressive fire on the transport ship. Occasionally, a shell would hit its mark, but Yesia would intercept it, showing no intention of flying over to attack them.

"Stop for a moment, let's replenish the ammunition first," Su Ming said.

The MK71's automatic loading system relies on a bottom-mounted rotary drum magazine, with a maximum capacity of 75 rounds. It was reloaded after the island attack, and now it's down to half full again.

Violet arranged for the strongest zombies to carry the ammunition, and the cannonballs in the ammunition drum were replenished again in just over ten minutes.

"Alright, let's begin!"

The White Triangle increased its speed by 10 knots, quickly closing the distance to the transport ship to 10 kilometers. It remained diagonally alongside the Orcs, keeping them to its right front and maintaining its absolute superiority.

Beanie's accuracy quickly rose to 30%. She increased her rate of fire to the maximum of 12 rounds per minute, and the opposing team began to frequently flash white lights indicating interception.

This is a numbers game; if the pressure from the artillery exceeds the opponent's tolerance, they will have no choice but to attack. If Yeshia remains inactive after a volley of 75 rounds—then another volley!
But this did not happen. Three minutes later, a white figure appeared angrily above the transport ship and flew over at high speed.

As expected of a Saint-level expert, her flight speed easily exceeded 40 knots. Considering she was flying against a Force 7 sea breeze, this speed is astonishing! There must be other mages on the transport ship, but their speed would be significantly slowed down under these weather conditions.

The enemy has been successfully divided!
