That is the sound made by the strange human-faced fish. It is inaudible to humans, but can be captured by instruments.
If Luo Yan was also a member of that army now, he would see circles of spreading ripples displayed on the sonar instrument.
This is a warning from the strange human-faced fish.
This is normal.
But the commander responsible for leading this main force, a senior colonel of the Drinking Horse Corps, frowned.
"Something's wrong."
"Why does it look like 'Wuzhiqi' doesn't know we're here?"
In Xia Houwu's deduction, 'Wuzhiqi' is the owner of the forbidden land and lives in the water area.
No activities in the water can be hidden from its eyes and ears.
Therefore, when formulating an action plan, Xia Houwu would use the main force as bait to attract the attention of 'Wuzhi Qi' and attract as many giant beasts as possible in the forbidden area to create space for the 'Decapitation' team to move.
But now.
It seems that 'Wuzhiqi' did not notice the arrival of humans, so it was not until now that the strange human-faced fish saw the mecha that it sounded a warning.
However, this is not much different from the original plan.
After the human-faced monster fish issued a warning, the forbidden area began to boil. Now the main force of the Corps is setting foot on the edge of the forbidden area, which is a relatively safe place.
Therefore, although the giant beasts in the water keep popping up, all that is displayed on the giant beast radar is the lower-level blue spectrum.
"Don't be careless!"
"Even if they are lower-level, they are home in the water. Although we have a deep-diving system, it is not as flexible as on land."
The senior colonel quickly issued an order over the communication channel: "Expand your formation and fight in with me."
The mechas immediately dispersed and entered their respective positions as usual training, thus forming a defensive formation.
In this formation, the shield-wielding machines were on the front line, and they set up long spears that could resist the impact and release high-voltage current.
The machine behind them picked up rifles. These rifles fired not the usual bullets, but special bullets specially designed for underwater monsters.
This kind of bullet has a slender shape and a sharp front end, which minimizes the resistance of the water when it moves in the water.
And after it hits the behemoth, the internal impact will cause the explosives in the projectile to explode, causing huge wounds.
Some bullets release strong electric currents, paralyzing the beast's muscle movements.
There are so many kinds.
At this time, the first batch of fish and beasts in the forbidden area had already swam closer. A dozen giant beasts of different shapes roared in the water, their eyes glowing red, and they rushed over with murderous intent.
The senior colonel of Yinma City said calmly: "Don't panic, hold on!"
"Wait until they get closer before attacking."
"Okay, now!"
"shooting!"
The colonel gave the order, and the mecha group behind the formation immediately concentrated their firepower to harvest the invading behemoths.
Those specially-made underwater rifles have no flames at the muzzle, only a large amount of gas is ejected from both sides of the gun body every time it is fired.
The special bullets are driven by strong kinetic energy and rotate, pulling out clear water lines.
They crossed the position, and then densely packed into the body of the forbidden beast like nails.
Soon, the skin and flesh of the dozen giant beasts were all torn apart. Some of the unlucky spots were fatally hit and died on the spot. Their bodies were still rushing forward, but their speed became slower and slower, and finally they floated in the water.
The lucky ones were not killed, but they were seriously injured. When they arrived in front of the battle formation, they were first blocked by the shield wall, and then spears were poked out from behind the shield wall insidiously.
Not only did these spears pierce their vital points, they also released high-voltage currents in their bodies, causing all these fish beasts to be electrocuted and convulsed.
Then the shield wall was removed, and the shooting team at the rear carried out the final harvest.
Rizhao Slope.
On the command platform in front of Luo Yan, the screen no longer showed the battle scene, but instead showed a floor plan of the forbidden area.
From this plan view, we can see that many moving arrows representing the Yinma Corps are steadily advancing towards the interior of the forbidden area.
Inside the forbidden area, there are many moving arrows coming from different directions. These are obviously giant beasts in the forbidden area.
They are converging and resisting the attack of the Drinking Horse Corps.
At this time, Xia Houwu's voice sounded on the communication channel.
"The main force has successfully attracted the attention of the giant beast in the forbidden land. It's our turn next and we are ready to go."
Luo Yan immediately concentrated his attention on the next action.
He saw the guidance personnel on the ground waving their arms and making gestures to direct the 'Albatross' transport aircraft.
Transport helicopters began to take off one after another, and each mecha was hoisted and transported by twelve to sixteen 'Albatross'.
Luo Yan looked out of the panoramic window. The group of helicopters responsible for transporting the 'Bi'an' were rising upwards. They were distributed around the mecha, and in the blink of an eye they were on top of Luo Yan's head.
At this time, there was a vibration in the cab, and then Luo Yan saw that the things on the ground were shrinking little by little, and soon the mecha's legs were far away from the ground.
It's not just 'Bi'an', but other mechas too.
Including Xia Houwu's 'Liefeng', all the machines involved in the 'decapitation' operation have left Rizhao Slope.
In the bright afternoon sunshine, head to the skies above the Forbidden Land.
Each mecha, hoisted by the 'Albatross', cast huge black shadows on the water.
In the cab, through the panoramic window, Luo Yan saw the river beneath his feet gradually widening, eventually connecting with the sea.
In a blink of an eye.
This 'beheading' team has arrived over the forbidden area and near the mouth of the sea.
"Prepare for airdrops, please all mecha masters turn on their shock absorbers."
No need to remind, Luo Yan has already turned on all the shock absorbers of the 'Bianyan'. When the countdown to the airdrop reaches zero, the hanging device on the aircraft body separates from the fuselage.
Each mecha roared and fell towards the sea like meteorites.
Luo Yan held his breath. After a flash of light and shadow flashed across his eyes, he felt his whole body shake. The 'Bi'an' had already crashed into the sea water.
The heavy body sank at an extremely fast speed after entering the water.
The mecha had closed all the vents and activated the air circulation system before it entered the water, so Luo Yan didn't feel stuffy.
The deep dive system also started to activate, allowing the mecha to dive faster.
At this time, the external lights of the nearby aircraft were turned on one by one, illuminating the world in the water, allowing Luo Yan to see that there was a city submerged in the sea under his feet.
The place where the mecha landed should be a playground. After all, Luo Yan saw a Ferris wheel that was mostly covered by seaweed.
In the distance of the forbidden area, you can vaguely see the flickering light, as well as the figures of mechas and giant beasts.
In that direction, the battle between the main force of the corps and the giant beast in the forbidden area was raging.
But here, it is unusually quiet.
Some people died, but not completely...
