The three naval arms are all classic arms in the Red Alert, and the only ones that can come in handy at present should be the Dolphin and the Akula submarine. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Both of these are good at underwater warfare, and the main target of attack is also the enemy in the water, and although the assault destroyer is strong, its main attack surface is the enemy on the surface and on land, and it is a bit chicken against the monster beasts hidden in the deep water.

Han Dao glanced at the cost of the three, the dolphin was 300 gold coins, the Akula submarine was 1000 gold coins, and the most expensive was the assault destroyer, which required 1500 gold coins. However, with the current funds of the base, he can still afford such a price, after all, the price of one bullet can build thousands of assault destroyers and Akula submarines.

At the click of a finger, 20 dolphins and 50 Akula submarines have been selected.

Dolphins under construction

Number built: 20

Estimated energy consumption: 6000 gold

Estimated consumption time: 1 minute (per head)

The Akula submarine is under construction

…………

Half an hour later

In the deep water, there were nearly a hundred shadows emitting a dark blue light at this moment, and 20 dolphins and 50 Akula submarines were neatly lined up, quietly suspended in the depths of the water.

"Squeak quack!"

The next moment, as if given some kind of order, the five dolphins and 20 Akula submarines had left the group and headed for the distance at a breakneck speed.

The number of demon beasts in the water exceeded 10 million, and it was definitely unrealistic, so Han Dao decided to draw them out one by one, and then concentrate his forces to kill them one by one, so that he could achieve very considerable benefits by using only a small number of troops.

Dozens of huge black shadows glided silently under the water, whether it was the dolphin or the Akula submarine, there was no sound, the dolphin as a specially trained and modified base creature, its tactical ability and intelligence are not inferior to a red guard soldier, at this moment knowing that they are gradually approaching the enemy, the five dolphins all tacitly stopped the habitual chirping.

As an anti-ship weapon, the Akula submarine uses electrical energy that does not produce any noise, coupled with the extremely streamlined titanium alloy hull, and there is no splash sound along the way.

Ten kilometers of water, for the professional-level Red Guard Navy, it only takes a few minutes to complete this journey.

At this time, you can see a virtual red line in the water area in front of you on the virtual screen, and the meaning of the red line is that the water area ahead is no longer under our control, and there is the possibility of the existence of monsters.

"Stop moving! All submarines are hidden on the spot, and the dolphins go first to explore the reality ahead! Han Dao ordered with a frown.

In the depths of the Tianhe River, the twenty Akula submarines that were moving at full speed quickly slowed down after receiving the order, and in the blink of an eye, they had dispersed, and all of them dived into the deep aquatic grass at the bottom of the river, and the five dolphins also changed their knife formation at this moment, carefully crossing the virtual red line, and probing towards the unknown waters.

As the five dolphins advanced, sound waves continued to emanate from their brains, sweeping around, probing all the monsters that might be hidden around them.

A hundred meters, nothing was found.

Two hundred meters, there is still no trace of any demon beast.

At five hundred meters, there is no trace of any biological existence at the bottom of the river, except for the aquatic plants that drift with the water waves.

…………

Until the dolphin advanced nearly ten kilometers further, the river was still empty, as if all the demon beasts had disappeared.

In the main base, a sneer flashed on Han Dao's face, he still overestimated the courage of these demon beasts, after a series of quality bullet strikes, these demon beasts were probably already shocked, at this time, the proton impact cannon had already stopped attacking, but within twenty kilometers of the attack point, there was never a single demon beast to be seen.

"Keep searching! The rear submarine should follow up and always keep a distance of five kilometers from the dolphins! Then hide in place! Han Dao ordered a little helplessly.

"Squeak quack!"

The five dolphins sped up and almost turned into five black lines, flashing through the water, and at this moment, ten kilometers away, twenty Akula submarines had already floated from the deep aquatic weeds at the bottom of the river, and followed the five dolphins far behind, catching up.

As the main attack force, the Akula submarine group must be close enough to the dolphins as reconnaissance and bait, after all, the dolphins' attack power is very limited, and if they encounter difficult monsters and the rear fire support cannot keep up, this reconnaissance mission is likely to be the last mission of their lives.

Ten minutes later

The dolphin has reached a distance of 30 kilometers, and five intersecting soundwaves have been pushed through the water, and the next moment, they have been reflected again.

Warn! Warn! Spot the enemy!

In the virtual screen, the five dolphins had stopped moving forward, but went directly into the aquatic plants below, and at the same time, the piercing warning sound of Zhi Brain had already sounded in Han Dao's mind.

Soon, the detection image has been transmitted back, more than six hundred meters ahead, out of the river and aquatic plants at this moment, there are two huge abnormal sound wave reflectors, lying in the water, almost cutting off the Tianhe waist, the preliminary estimate of the size of both are about thirty meters, even among the many demon beasts in Tianhe, they are also absolute behemoths.

"Approach carefully!" Han Dao gave the order.

In the aquatic grass, five dolphins drilled silently, constantly approaching the existence of the demon beast in front of them.

"Roar! Roar! ”

Just when the five dolphins reached a distance of 300 meters from the target location, two huge sound waves suddenly came from the front, and the rolled up water waves directly caused the five dolphins to fly directly out of the aquatic weeds and roll backwards in the water for more than ten meters, which slowed down their bodies.

At this time, the scene in front was also taken into the eyes of five dolphins, three hundred meters away, two ugly fish with a length of dozens of meters floating in the water, staring vigilantly at this side, the roar just now was also made by them, and behind the strange fish in the past two days, there were also dense all kinds of demon beasts, and at this moment, countless pairs of fierce and bloody eyes were looking at this side.

However, these monsters seem to have a deep sense of fear of the waters here, and although they are a little restless at the moment, they only use their roars to warn the five dolphins, including the two giant monster fish in front of the attack, and none of the monsters dare to chase after them.

"Didn't even take the bait?" In front of the virtual screen, a trace of embarrassment flashed on Han Dao's face, he thought that as long as these demon beasts found five dolphins, they would be desperate to catch up, but the reality showed that they were not stupid.

Han Dao could even see the slightest glimmer of wisdom in those bloody pupils.

"In that case, then take the initiative to close the distance and authorize you to use taunts on the enemy!" Han Dao pondered for a while, his eyes suddenly lit up, he remembered the classic taunt skill when playing games before, as a bait for pulling monsters, always using all means to provoke monsters and make them lose their minds, and then frantically chased the bait.
