Chapter 1441 Sonar

Brian's eyes flashed: "Then you let people blow up the higher entrance to Shadowmoon Valley and let a huge amount of water pour into Shadowmoon Valley?"

Duke smiled.

Everything was calculated by the system. After scanning the entire topographic map of Shadowmoon Valley, the system elf gave a rare prompt asking Duke if he wanted to do "Brother Guan floods the seventh army"?

Duke decisively said 'yes'.

When I came to Shadowmoon Valley as a player before time travel, I didn't think Shadowmoon Valley was that bad. At most, it was a depressing sky, a slightly nauseating atmosphere and color rendering.

It was only when I came to Shadowmoon Valley that I realized that this was really no place for humans.

On the black land eroded by evil energy, dry and smelly wind is blowing everywhere, and the air is filled with a disgusting smell. There was no clean water source anywhere. After flying for a whole day on a griffin, all you could see were lakes of fluorescent green evil energy.

The bright green color makes people easily think of Nuka-Cola, radiation sickness and the like.

Duke extremely doubted that any normal person would turn into a demon and become neither human nor ghost after staying in such a place for three months.

The dwarves who tried to build the Wildhammer Fortress in the past had to dig deep wells, then extract the muddy water, filter it, and then pour in large bottles of Shattrath holy water to neutralize it before they dared to drink it.

Building a castle, even if it is a mechanized operation, is heavy physical labor, and moisture is essential, otherwise people will die.

Anyway, to clean up those scattered demons, Duke simply flooded the entire western half of Shadowmoon Valley.

Looking down from the airship, this sea-like scenery is far from endless, but it has a more shocking effect.

The air fleet entered Shadowmoon Valley less than twenty kilometers away. Geographically, they had just entered through the narrowest funnel-shaped entrance on the ground.

If the waterline comes from the west, you can still barely see the end of the waterline. With the basin-like structure of Shadowmoon Valley, the flat area becomes larger and larger from west to east. After the water wave pushed over, it formed a long arc, so long that the edge was almost invisible.

Only to its north and south can you barely see the end. Shadowmoon Valley is shrouded in a large amount of evil energy fog, and the light is quite poor. Even if you look through it with a telescope, you can only see undulating pale shadows.

Even though he knew that it was the mountain line that surrounded the entire Shadowmoon Valley, he still had a vague feeling that it was the interface between the sea and the void, as if it was just the dark black oil paint of an artist's brush.

Under the outline of the long mountains to the north and south, there is a turbid lake that is a little green. It's not a vast expanse, but the feeling of having all the junk washed away is quite refreshing.

The air fleet continued to move forward. It took more than an hour to arrive at the site of the Wildhammer Fortress that had been abandoned before. It was a typical hill. Although it was not too high, it was still a good distance from the valley floor. More than 100 meters.

The body that was not snatched back in time had been devoured by wild beasts until only a few bones were left. The remaining abandoned city walls still bear the devil's arrogant claw marks.

Only now everything is different.

Hellfire, aren't you awesome? Everything burns. Do you have the ability to evaporate this huge sea-like lake?

Cerberus, aren't you very fast? Show me if you have the ability to accelerate from zero to 100 kilometers in water in 3 seconds?

Although the former site of Wildhammer Fortress against the southern mountains now looks like an isolated island in the vast ocean, the Burning Legion, which is only good at land and air combat, has no way of passing through this vast and vast lake.

After getting off the flying battleship, Mark Dooku and his men stood on the edge of this 'peninsula', looking extremely relaxed.

Brian called to his men: "Boys, work quickly! I will see a preliminary beachhead blocking position with anti-aircraft firepower within half an hour."

Kurdran Wildhammer disembarked from his gryphon king Skyree and flew for three hours from Windrunner Fortress. Even the gryphon king was a little tired, let alone the other gryphons.

"Hey, Duke, can't you ask your Storm Naga to control this water area? Then we only need to guard against enemies coming from the sky."

Duke shook his head and pointed to the fluorescent green water: "You swim in it every day. If you don't have the Holy Light to help you expel the evil energy in your body, I don't think you can become a demon."

If there weren't a lot of evil energy in the water, Duke would really mobilize the naga for defense. After all, the demons of the Burning Legion are almost all-terrain explosive creatures.

Many demons can breathe better, and they can get away with being unable to breathe.

Duke has read the records: In the past 25,000 years, the Burning Legion has been able to conquer and destroy even gaseous creatures on gaseous planets, let alone small water attacks.

This is merely an obstacle, not an insurmountable barrier.

Of course, the small-scale Naga troops are still prepared.

There is a thousand-man elite Naga team on the transport ship. If the pressure on the front line is too great, Duke will join this team of Nagas. At worst, I'll bathe Naga with the diluted holy water from Shattrath City.

However, for three days in a row, it was without any surprises. While demons do surface like the Loch Ness Monster, not many actually attack the fortress within the building.

It is more the instinct of low-level demons that drives scattered demons to break into the defense circle of the fortress.

The arrivals were irregular. Sometimes one or two hellhounds would come to deliver food, and sometimes a whole group of demon guards would actually come.

This caused great pain to the defenders, so they could only deploy as many troops as possible, divided into four teams, and rotated every two hours. No less than 3,000 defenders were deployed on the shore positions at each time.

After three days, even if they had to stand in military position for two hours every six hours, the morale of the troops was obviously low. After all, no one knows how many more demons will follow after the first demon emerges from the water.

Sending out Naga scouts is not easy to do. There is a lot of green evil energy in the water, and the water is turbid. The detection range is quite limited, and there is also a possibility that Naga will not come back after being killed.

"Okay, this is forcing me to make more moves." Duke sighed.

Early on the fourth day. On the temporary dock, everyone saw a strange-looking new machine with some parts extending into the water.

Duke stood in front of the machine and proudly announced to a group of dwarves, gnome craftsmen and scientists:

"Hello everyone, welcome to watch the latest masterpiece of Marcus Future Technology Co., Ltd. - the underwater sonar system. Sonar is a system that uses the propagation characteristics of sound waves underwater to complete underwater detection and processing through electroacoustic conversion and information processing. Electronic equipment for communication tasks. Our new passive product belongs to the category of acoustic positioning. By listening to the noise in the water, we can roughly determine how many and what size enemies are coming underwater."
