Xu Mu could fully understand the policies of the island countries. After all, they were facing the threat of ocean monsters.

Ocean monsters have a distinctive feature: when they are in the sea, their strength will increase significantly, surging to three times the original strength.

The original intention of building the Naval City was to curb or weaken the ability of the sea monsters and deprive them of the strength increase they gained in the marine environment.

Every time a sea monster invades, it will cause great damage to the Sea War City. If the monster corpses are handed over to the magician for use...

The official finances of any country could hardly bear the sustained economic pressure and could not support the construction of Haicheng City.

In addition, since the corpses of sea monsters are extremely rare, their value is much higher than that of land monsters.

With the same strength, and without spirit, the value of a sea demon's corpse is approximately 1.5 times that of a land demon's corpse.

If the land monsters are likened to the elemental fire seeds among the elemental spirit seeds, then the sea monsters can be regarded as the elemental thunder seeds.

Handing over the corpse of the sea monster to the officials of the island country will cause some losses to the wizards who defeated the monster, but the losses will not be too great.

"Oh, your team leader asked me to tell you that you must be promoted to a four-star team while in Donghai City, otherwise the reward you are looking forward to may fall into the hands of other countries."

"When I first heard your leader say that, I thought there would be an experienced group of mages coming, but I didn't expect that there would only be a bunch of young and energetic kids like you. For you, being able to survive the tide is already a good achievement."

Lai Hengbao laughed sarcastically, his eyes full of contempt for this group of young people.

Lai Hengbao was not clear about the true meaning behind these words, but everyone else present knew it.

If they want to seize high-level resources from other countries during the training process, they must successfully be promoted to a four-star team during this training.

Ai Jiangtu asked, "What are the criteria for evaluating a four-star district team?"

"The evaluation of the four-star district team mainly depends on your performance in various operations, including defense, hunting monsters, performing rescue missions, charging into battle, and participating in special operations."

"If you perform well, someone will naturally record your achievements. This is somewhat similar to the Hunter Alliance's rating mechanism for hunters. The number of demons killed and bounty missions completed will be converted into points. Once a certain number is accumulated, you can be promoted to a four-star team."

"Based on your current situation, it will take at least four or five years to achieve this goal," Lai Hengbao replied.

After understanding the situation clearly, Lai Hengbao left the scene and specifically reminded everyone that there would be a high tide the night after tomorrow, so they were asked to put on their combat uniforms in advance and be prepared for battle.

After hearing this description, Zhao Manyan couldn't help but sneer, "These islanders are really smart. They turned the Dadonghai battlefield into their own territory, and then, like contracting land, they handed over each area to trusted individuals to run."

"The island nation's government is enjoying the benefits, not only collecting rent, but also purchasing all the 'seafood' at extremely low prices, while the army and the Magic Association have become spectators behind the scenes. Only those hunters and mages who are eager to get rich through war are dying in vain on the front lines."

After hearing what Zhao Manyan said, everyone nodded deeply touched.

The original tasks of killing monsters and guarding and charging into battle have now almost become the exclusive work of individual mages. In order to gain more benefits, they will do their best.

The island government only needs to ensure order and stability, establish some basic rules, and then sit back on its high embankments and enjoy the benefits.

“These matters are not within our scope of responsibility. We were assigned to the 20th block, which is very close to the 19th block where we encountered the Blue Valley beast before.” Nan Jue said slowly.

……

……

The deafening roar seemed to tear the eardrums apart, and the loud and passionate shouts of the island nation's wizards came to my ears, with looks of fear and uneasiness on their faces.

Obviously, this tide was beyond their expectations, and even the originally carefully arranged formation had to be adjusted temporarily.

Donghai City is divided into thirty-two blocks in total, and there are several mages standing on every roof in every block.

Looking down from a high place, the number of these mages seemed extremely large, and the tide that appeared this time was by no means comparable to the original tides in nature.

Even the most turbulent tide that ordinary people have ever seen is only a dozen meters high.

But the height of this tide far exceeded people's imagination.

The sea water poured into the city like an angry beast, carrying the broken debris of the previous buildings and rushing towards the streets after Block 16.

This row of buildings, which had not been fully prepared, suffered a devastating blow in an instant when faced with such a fierce attack.

Some collapsed directly, some were broken in half, some tilted and collapsed, and some were smashed to pieces by the tilted and collapsed buildings...

The debris in the sea was like a deadly weapon, driven by the waves and flying towards the crowd.

Although the impact of the waves themselves may not be too great, the debris mixed in them is enough to be fatal.

“I finally understand why the buildings here look so new. It’s because they’ve been destroyed repeatedly and rebuilt every time. Damn it.” Zhao Manyan couldn’t help but curse.

The sea fog was thick and it seemed as if it was pouring rain, soaking everyone.

When the tide poured into Donghai City, it was cut into countless torrents by the buildings, each of which was like a sudden flood, submerging the streets and the lower part of the buildings.

"These buildings were specially reinforced to protect against tides, but we didn't expect so many of them would be washed away. Our space for movement has been reduced all of a sudden."

Jiang Yu stood on the edge of the building, watching the violent tide rushing past the house. His heartbeat accelerated, pounding non-stop.

“Woooo ...

Just then, the cry of a baby came from below, the voice full of fear of the impending disaster.

“Oh my god, whose child was washed into the water!” Zhao Manyan also heard the crying and shouted hurriedly.

"Has your brain been eaten by a one-eyed demon wolf? You can't even find an ordinary person in Donghai City, and you still want to find a child? What's the difference between this and looking for gold in a cesspool?" Xu Mu couldn't help but curse.

“Hiss, I was so busy trying to save the child that I almost forgot that this is the front line.” Zhao Manyan said somewhat embarrassedly.

"Then is the crying sound of the baby a demon?" Zhao Manyan asked again. "Whether it is the sound of a demon or not, we should go check it out. If it is really a baby crying, we must rescue it; if not, we should destroy it directly." Ai Jiangtu gave the order decisively.

"I'm going to save that child."

Nangong Ni said without hesitation, and quickly rushed to the direction of the baby. She came to the other side and saw a sleeping bag floating in the rapids, and the baby's crying came from there.

Nan Rongni immediately summoned her plant-type magic vines and weaved them into a vine ladder. With the help of the vine ladder, she successfully slid to the side of the large sleeping bag that was being carried away by the water.

Just as Nangong Ni was about to touch the sleeping bag, a smooth forehead suddenly stretched out from the sleeping bag. However, it was not a baby's forehead, but a huge tumor growing on the head of an ugly monster!
"Be careful, that's the White Weeping Demon, back off quickly!" Jiang Yu shouted in horror.

Although Jiang Yu's warning was fast enough, it was still insignificant in the face of the general-level White Weeping Demon.

The Baiqi Demon is a general-level demon, and its strength is at least at the mid-level general-level. Even a mid-level mage who majors in speed finds it difficult to resist its attack, not to mention Nangong Ni, a mage who focuses on healing.

The White Weeping Demon suddenly burst out from the sleeping bag, its tentacles like a violent beast, frantically chasing after Nangong Ni.

The tips of these tentacles were like sharp cones, flashing a cold purple light and carrying a breath of destruction.

One of the tentacles stabbed towards Nangong Ni's calf at an astonishing speed, so fast that people could not react.

Nangong Ni didn't even have time to summon her magic armor before her fair and slender calves were pierced through by the creature's cone tail and nailed to the cold wall.

Blood gushed out instantly, staining her white dress red. She tried to use magic to control the magic vines to pull herself up, but the powerful impact made her efforts in vain.

"thunderbolt!"

A dazzling bolt of lightning, like a divine punishment from heaven, instantly tore through the gloomy sky and fell directly on the body of the White Weeping Demon.

Amid a deafening roar, the White Weeping Demon's body was instantly torn apart by the power of thunder and lightning, turning into a rain of blood that fell down. It was bloody and tragic, and it made people shudder.

Ai Jiangtu said solemnly: "Guan Yu, go and bring Nangong Ni back. The army of sea monsters is about to arrive."

Not long after the White Weeping Demon died, many creatures with fan-shaped fins on their heads emerged from below. They were green in color, with rough skin, and their lower bodies were frog-shaped. They could swim in the water and stand on land.

These creatures do not have the White Weeping Demon's tentacles, but their front paws are gear-shaped and as sharp as saw teeth. Once they chop at a human body, they will definitely cut bones and flesh.

“They don’t have scales, so they should be easier to deal with.” Nan Jue analyzed quickly.

Siren creatures are divided into several levels. Even if slave-level sirens have scales, they are usually just for decoration and have limited defensive effects. They mainly rely on skin and flesh.

The body of a warrior-level siren is relatively rough, with thick skin and bumps. Certain parts of the body often evolve into weapons, and the melee combat ability is extremely strong.

Commander-level sirens are mostly covered in scales and armor, and their entire bodies seem to be wearing metal clothes. They are highly resistant to mid-level magic and are unlikely to pose a threat.

Judging from the skin and flesh condition of these serrated green monsters, they should be warrior-level creatures.

They were already adept at fighting the warlord-level creatures, however, just when everyone was about to breathe a sigh of relief, the sea water on Broad Street suddenly surged, and more monster heads popped out of the sea.

These heads have fan-shaped fins. Looking from above, they look like giant sea urchins. The dense fins quickly covered the entire street, making people feel unprecedentedly depressed.

This wide street is the protection place of their team. As the thorny fins become more and more dense, everyone's mood becomes heavy.

"You deal with the sea monster ahead." Ai Jiangtu said to Xu Mu.

"Okay." Xu Mu responded.

"Whoosh!"

"Whoosh!"

Relying on their amazing jumping ability, the sawtooth green monsters quickly jumped out of the water and climbed onto the narrow balconies.

These balconies were originally a place for mages to stay, but now they are occupied by these extremely ferocious monsters with jagged hands. There is a death light flashing in their gray eyes, and they are full of desire for battle!

"Twelve green jagged monsters, need help..."

Jiang Yu was just about to ask Xu Mu if he needed help. After all, there were twelve warrior-level sirens, and even a high-level magician would need to be cautious in dealing with them. But before he could finish his words, Xu Mu waved his hand.

I saw him weaving a purple-red lightning whip in his hand and swung it around, easily killing the twelve saw-toothed green monsters around him.

"Don't worry about me, go support the others first." Xu Mu said to Jiang Yu.

"Got it." Jiang Yu didn't hesitate too much and immediately took his summoned beast to other places to assist other teammates.

As time went by, the number of sirens around continued to increase, and the people who had been scattered due to the broken formation also gathered together again. Only two high-level mages, Xu Mu and Ai Jiangtu, were still fighting alone.

After an unknown amount of time, Mo Fan finally came back, and the tide began to recede, revealing the wreckage of buildings scattered on the streets.

Although it is impossible to accurately count how many sirens have not been eliminated, they will leave one after another with the receding tide. Without the support of seawater, their survival rate will drop significantly and their strength will be greatly reduced, so there is no need to continue to entangle with them.

The drainage system of Donghai City is exceptionally powerful. Even for a city that has suffered severe flooding, it usually takes at least one to two days to completely drain the accumulated water.

However, as the tide receded, the water level dropped only below the low embankment, leaving only a small amount of shallow water in the wet urban area, as if it had only experienced a short rainfall rather than the flooding that was once as high as ten meters.

The speed of the city's destruction and reconstruction is equally alarming. Once the battle is over and peace begins, military mages will patrol near the low dike to prevent the sirens from counterattacking.

At the same time, the cleaning team acted quickly and efficiently. Not only did they clean up the ruins thoroughly before dark, they also properly disposed of all the bodies of the sirens to ensure the hygiene and safety of the city.

Demon remains are one of humanity's most valuable resources, as they occupy far more territory than humans and are rich in resources.

These resources provide demons with powerful strength, making their bodies extremely tough, which means that the bodies of demons contain rich natural essence.
