Roland had consulted Sukhoi and Morozov in advance about mines, and learned that the construction of mines in the world of Vares, at least in the North Sea region, was similar to that of mines on Earth, but at the same time very different. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

The similarity lies in the fact that the main structure of the mine is a huge sealed jar, which is fixed by anchor chain in the waters where the current is relatively gentle in and out of the strait, because it floats ten feet below the surface of the water, and the shell is painted with blue-black camouflage, which is difficult to detect by conventional surface reconnaissance methods.

Today, warships of all levels in the North Sea region, including the vast majority of ocean-going merchant ships, whether you are sail powered or vapor powered, the waterline is not less than ten feet, once you pass through the area where the mines are laid, it is inevitable to collide with them, and then lead to the explosion of the mines, the large tank wrapped in copper shells contains nearly 1,000 pounds of alchemy gunpowder, the destructive power of the explosion is enough to blow through the bottom of the ship, and the waves will also pose a great threat to other ships nearby.

The difference is in the technical details of the mines. Varess is a magic-led fantasy world, so mines are inevitably magical, mainly in the form of detonating tubes.

In addition to the ordinary trigger fuse, the mines on Monster Island are also equipped with "induction fuzes". Roland knows that mines on Earth also have induction fuses, such as inducing the magnetic field and water pressure changes when a battleship passes, while the mines produced by the Giant Demon Island Arsenal use a constant "magic alarm" to achieve a similar purpose, and also have some unique advantages.

The "Magic Alarm" is a very common 1-ring protection spell that monitors a 20-foot radius, triggering an alarm and causing a high-pitched noise caused by an intruder, which can trigger a mine without having to hit the bottom of the ship directly. For passing ships, such a mine is like a large near-miss, and the shock wave and turbulence generated are so terrible that ships with smaller tonnage can even be overturned.

The Warlock of Giant Island used the above warning mechanics when designing mines, and improved them.

First of all, 20 feet of alarm range is not enough, by adding special casting materials can increase the alarm range by 10 times, and then several magic alarms can be connected into a chain to form a secondary recursive structure: one alarm is triggered and then another alarm is triggered 200 feet away, and the layers of transmission will eventually detonate the mine, in this way the defense area of each mine can be expanded, causing a greater threat to the intruder.

Another benefit of using a magic alarm as a sensing fuse is that it can be set to target. The ships of the Giant Isle have a common feature: the bow is adorned with a statue of the Kraken. Kraken personally blessed the ship's bow statue, and when it approached the minefield, it would emit a magical aura, and the mine would not trigger an alarm when it sensed this special aura.

Other ships that were not equipped with a Kraken bow statue would not be able to traverse the mine-ridden waters without being navigated by flying sharks sent from the island.

Helena was interested in navigating the fleet, but she had a more important responsibility and couldn't reveal her identity yet, so she couldn't help it.

At the same time as Roland and his party were airborne, Helena had already led five warships led by the "Sea Palace" through the minefield, and the Victoria fleet hanging behind could only find a way to break through the danger by herself.

Roland landed slowly at high altitude in mechanical armor, the weather was clear in the afternoon, there were no clouds and fog in the sky, and it could be clearly seen that Victoria's flagship "Yanbo" waved the flag and ordered the warships under his command to reduce their speed so as not to accidentally enter the minefield, while the two destroyers broke away from the fleet and advanced side by side into the minefield.

Witnessing this, Roland immediately understood Victoria's intentions: to send two destroyers with small tonnage and flexible movements to the front station and take on the task of clearing mines.

There are currently no professional minesweepers in the North Sea region, and it makes sense to leave the drudgery of minesweeping to destroyers. Destroyers are originally specialized in all kinds of dirty work, and when they need death squads, they will be sent to charge in a wave, in case they sink by a mine...... It's better than hanging up the capital battleship with a larger tonnage.

The captains of both destroyers had excellent manoeuvring skills and kept the relative distance just right, while the more critical task of minesweeping was carried out by the navigators of the two ships.

Roland opened the "Eagle Eye Technique" attached to the mecha force field window, and he could clearly see a circle of figures wearing magic robes and holding magic wands standing on the bow terrace of the destroyer, as many as eight people.

Ordinary destroyers are usually only equipped with two or four navigators, and now in order to carry out the minesweeping mission, a group of elite soldiers from other warships are temporarily transferred, and after approaching the minefield, they all raise their wands, which shows that they are very nervous.

The two warships, with a total of 16 nautical warlocks, all held the "Extended Disarming Staff" in their hands, unleashing the "Regional Dissolving Magic" enhanced by "Spell Enhancement", and the green arcane light swept past one by one, carefully cleaning the sea in front of them.

The Magic Mine is triggered by a "Magic Alarm", and when the "Magic Alarm" is disarmed, the mine will not be able to sense nearby ships and become an ordinary "Drifting Mine".

The two destroyers advanced all the way to the minesweeper, while the main fleet in the rear, led by the flagship, cautiously followed up, lined up in a column, and passed through the minefield along the safe channel from which the minesweepers departed.

Not long after the main fleet entered the minefield, a frigate deviated slightly from the safe course, and unfortunately touched the mine, and a huge wave rose into the sky, and the bow of the ship was blown away on the spot, and the hull quickly tilted and sank.

The sailors on board hurriedly pushed off the lifeboats, abandoned ship and moved to other warships. The casualties were not large, but the roar caused by the thunder clearly alarmed the pirate fleet ahead, and immediately raised flags to warn each other and hastened to escape from the minefield.

"It's a bit troublesome!" Roland sighed secretly when he saw this, and the last thing he wanted to see happened.

"a bunch of fools! In the end, it was still a thunderstorm! Bloom yelled.

"Lady Sindra is fair, luck can't always be on our side," Roland comforted his companion through the "Psychic Connection", "The navigator can only find mines, but it is inconvenient to completely remove them, since one has already been blown up, we don't care about blowing up more, let's go down and open the way, and directly blow up all the mines in our way!" ”

Boom!

Roland continuously pulled the ring finger of his right hand, and the large saber popped out from the right wrist of the mechanical armor.

With a backhand slash to cut the cable behind him, Roland broke away from the parachute and fell into the choppy sea.
