Due to the previous entanglement of the lizardmen soldiers, the cruiser fleet ran a little farther away, and below the surface, the swordfish people chased all the way, trying to launch another round of attacks, and further speed up the sinking of the cruiser.

For this situation, the captain of the cruiser, probably expected, and with the sound of the whistle, a strange device installed in the tail of the cruiser quietly opened.

Immediately afterward, with the muffled sound of the ocean current, one after another special oval-shaped objects were thrown.

At that moment, the sailfish people, whose speed had gradually increased, did not have time to make any more movements, they were moving at high speed in the current, and at the moment they came into contact with those objects thrown from the cruiser, an earth-shattering explosion completely swept them into the crazy surging current, and the huge waves splashed directly and completely exploded the entire sea!

However, this was just the beginning, and soon, the second, third, fourth! Successive explosions raged wildly beneath the surface of the sea.

From the center of the explosion, carrying the current, the impact that continued to spread, even the lizardman soldiers who had fled far away early could clearly feel it, and then their faces showed palpitations.

They did know that the warship of their Ten Thousand Worlds Civilization was equipped with a new weapon called 'Depth Charge', but they did not expect that the explosive power of this new weapon would be so strong.

However, how did they know that the original depth charges, although they were used as anti-submarine weapons, were not so destructive.

It's just that after Bart Brute Hammer received the design drawings, combined with Luo Ji's request, he learned that this depth charge was to be used to deal with those deep-sea monsters, and he was suddenly inspired, and he was stunned to develop an improved and enhanced version.

While increasing the depth of the depth charge, it also greatly increases the explosion power of the depth charge.

At the same time, the trigger mechanism of depth charges has also been further improved, becoming a dual mechanism.

The first mechanism is that, like a conventional depth charge, it explodes after it is fired and reaches a certain depth.

The second mechanic is a triggered explosion.

How did Bart do it, anyway, Luo Ji didn't know too much, and at the same time, he was not that material, but the dwarves' super talent in developing thermal weapons had to be admitted, although the cost also skyrocketed......

But in any case, after the successful development of depth charges, Luo Ji naturally hurriedly asked the arsenal to start mass production, and successively installed special bombardments on the cruisers of his South China Sea Fleet and Yangtze River Fleet.

After all, since he already knows the outer seas, and the army of fishmen on the Europa side has begun to do whatever he wants, then his side, even if it is out of the psychology of prevention, should be prepared early.

However, even Luo Ji himself didn't expect that the hand of this fish-man army would reach him so quickly.

In addition, due to the problem of messaging efficiency, what he also didn't know was that as early as a week ago, the foreign combined fleet located in the outer waters of the South China Sea had already been one step ahead of him and was patronized by the fish-man force.

After Shahrir's strategic-level Judgment Day Wheel back then, this wave of losses is estimated to make several exotic players have a stomach ache for a long time.

And Luo Ji, it is only now that he has obtained this news from the outer waters of the South China Sea through the channel of the elf druid.

As for the fact that his South China Sea cruiser fleet was also attacked by fishmen, it took another two days for him to receive the news.

This situation undoubtedly surprised Luo Ji, and he hurriedly asked the Imperial District to send five reconnaissance airships to the sea to conduct intelligence reconnaissance work.

Here, it must be mentioned that this reconnaissance airship, referred to as the reconnaissance airship, is a functional version of the Ten Thousand Worlds civilization after completing the manufacture of the goblin airship, reducing the cost and size.

Even if the size of the main airbag is calculated, it is only 20 meters, and at the same time, there are no weapons and aerial bombs on it, only a simple radio communication equipment and radar detection device, as well as some corresponding instruments and items.

Just like its name, it is not for combat, but for reconnaissance, and belongs to the typical auxiliary units.

Unlike those planes that have to obediently land after flying a circle, with sufficient fuel and supplies, this reconnaissance airship has been tested to be able to fly in the air continuously for half a month without landing.

Their relatively slow flight speed, coupled with their super ability to stay in the air, make them an incomparably excellent aerial reconnaissance unit.

Even to a certain extent, the reconnaissance ability of the reconnaissance airship is stronger than that of the elven druid, after all, the elven druid cannot fly around the world with bulky radio communication equipment on his back, and at the same time, it is even more impossible to fly for half a month without landing.

However, the elven druids also have the benefits of the elven druids, who are more flexible when they become giant eagles, and at the same time, they can also use the cover of the eagle spirit transformation to make further observations.

In this way, Luo Ji combined them quite simply.

Each recon airship, in addition to the standard goblin pilot and a series of necessary airship staff, is additionally equipped with an elven druid so that they can handle all kinds of situations.

The order from this side was given to the five reconnaissance airships located in the Imperial District to be dispatched quickly.

The field of vision in the air is extremely broad, just a reconnaissance airship, its daily reconnaissance range is already quite huge, five airships are dispatched at the same time, almost allowing Luo Ji to obtain an aerial vision of the entire outer waters of the South China Sea at once.

The most important thing is that they can directly transmit information back as quickly as possible through radio communication devices.

At the same time, for the sake of prudence, he also successively dispatched reconnaissance airships to several other sea areas around the central continent and began to carry out long-term reconnaissance missions.

This kind of practice, the consumption is definitely a lot larger, however, now is not the time to save that little bit of dispatch funds, anyway, the latest World Cup of his Ten Thousand Worlds Civilization has begun to make a profit, according to the current momentum continues, in the next few quarters, and even in the next few years, the financial situation of his Ten Thousand Worlds Civilization is relatively abundant.

In this way, after arranging all the things that should be arranged, Luo Ji refocused his attention on the report sent by the South China Sea Fortress in front of him......
