White Fog Lake, a twin peaked island in the middle of the lake.

"In the future, a water dungeon will be built here, water monsters will be imprisoned, and little Naga will be cultivated, so it is better to call this place Naga Island." When Alan chose the island, he made such a suggestion, and everyone thought it was interesting and agreed to it.

After a few days of research, Allen and the others came up with the data, and were surprised to find that the water monster in the White Mist Lake had grown to more than 20,000.

Shirley, Jock Circus and others didn't have much feeling about this amount, but Alan was really shocked!

You must know that the combat ability of every adult water monster is stronger than that of a first-order human adventurer. These more than 20,000 water monsters, if they form an organization, the entire three towns of White Fog Lake will probably fall in one day.

The nearest town to Naga Island is called Akere Fog Town, which is the farthest town from the shore of the three towns of White Fog Lake, with a total of more than 20,000 residents, most of whom are fishermen who live on the fish in White Fog Lake.

In addition to the towns of Inari and Akere, to the south of the White Mist Lake, there is also the town of Libos, which has risen due to the freight of the docks, and together with Inari, the town of Livos controls the shipping on the White Mist Lake, and the shrewd Livos people help the merchants from the south to find their way in the dense white fog, avoid reefs and water monsters, transport goods, and earn money.

After Allen and his party came to Naga Island, they cut down some trees on the island, opened up several hectares of open space, and built several houses with the help of the residents of White Mist Lake. At the same time, Alan spent nearly 20,000 gold coins to build a biological research laboratory on Naga Island, based on his experience in his previous life and the advice of Manuel and the Banshee.

Manuel and the Banshee became the lab's first researchers.

Compared to the earth, the Divine Grace Continent has not developed "technology", but with the superior adventurer career system of the Divine Grace World, the people here also have a high level of production. In just two weeks, Allen dispatched 11,200 units of wood, 9,000 units of stone, 6,500 units of metal and various minerals from other parts of Morel.

After several days of research, Alan devised a prison for the water monster. On Naga Island, there is a piece of land that will be covered by large water when the lake is flooded, and this area is the place where Alan has his eye on the water prison. The two peaks of Naga Island are located on the east and west sides, with the middle land being 3 km long and 1.1 km wide.

In Allen's design drawings, the 3-kilometer-long and 2-kilometer-wide strip of land is where the water dungeon is located, and in order to build the water dungeon, Allen has undergone several precise studies and calculations with the system. In the end, Allen chose to build a 3-kilometer-wide embankment on the north and south sides of the land, and used the principle of a communicator to regulate the amount of water in the embankment.

The dam is high in the north and low in the south, with an average height of 17 meters, and one-third of the buildings are submerged in water, and when Allen opens the gates, the giant connector of the dam will drive the water level to rise, and soon Naga Island, an area that is usually only flooded when there is a big flood, will form a huge lake.

In order to speed up the progress of the project, Alan found Shirley and the Ice Mage.

"The three of us join forces and can work a miracle."

Alan said this to the two girls mysteriously.

A day later, when more than 3,000 residents of Baiwu Lake applied for the construction of the island and came to Naga Island, they were surprised to find that the island in the lake that no one cared about had changed. A temporary dam 15 meters high rises above the lake, and the water temperature has dropped by at least 6 or 7 degrees Celsius within a radius of several kilometers on Naga Island.

It turned out that in the past night, Alan took Shirley and Ice to the bottom of Naga Island and built an ice wall with the first-order ice sealing technique. A temporary dam was built with a cube-shaped giant ice stone 3 meters long, 3 meters wide and 3 meters high.

When Eren dives into the water for the first time with the two mages, Shirley and Ice are still puzzled.

However, when the ice wall stretched for several kilometers and was layer upon layer, Shirley and the others were surprised to find that Alan had planned to build an ice wall between the island and the lake to speed up the construction of the dam and dungeon by the residents.

It's truly a miracle.

"How do you know we can do this?" When the first dam was completed, Han Bing looked at the large-scale ice wall that stretched for miles, and knew for the first time that he actually had such a powerful strength.

The water of the White Fog Lake hit the ice wall, as if it was impacting a crystal, but it could not cause any damage to the structure of the ice wall.

Shirley looked at such a scene, and fell into shock, the little girl never thought that she had such potential. When she was in the lake, Shirley lost her strength again and again, but Brother Alan followed her, using the water elemental spirit again and again to help her recover her mana, and because of this, Shirley was able to grit her teeth and persevere to the end.

Looking at the two mages looking at the temporary dam with pensive expressions, Alan knew that his acting leader this time had completely opened the mage vision of Shirley and Ice!

In fact, as early as when Alan was healing the ice of his dragon vein body, he had already realized that Shirley and Han Bing had the strength to build an ice wall. In order to resist the powerful onslaught of Victor's army on the plains, the Race Alliance in the Icefields gradually developed defensive tactics in the middle and late stages of the war.

In the initial actual war, an ice mage, even a legend, wanted to build an ice wall that covered the battlefield and stretched for dozens of kilometers overnight, it was very difficult, even if the ice wall could be condensed, it would be easy to be washed away because of insufficient tension. Therefore, the so-called ice wall tactics are simply not practical.

Later, the great goblin engineers invented the ice-stone tactic.

At night, the Continental Race Alliance sent a pair of mage teams, each of whom was responsible for building 3*3*3 size ice stones, composed of warriors and wind mages to form engineers, build defenses overnight, and then the legends imposed a giant magic circle, so that in a dozen hours, the mainland army could build a fortification that was invincible to the boulder wall.

Actual combat statistics show that this kind of fortification, which is made of giant ice stones one by one, is three times more stable than the ice wall built by mages in one go. Once introduced, it quickly became one of the mainstream tactics on the northern battlefield.

Now, although Alan does not have an ice mage group around him, only two lovely mage beauties, but one of these two has a high level of ice and has the potential to become the first ice mage of divine grace; One person awakened the heart of ice, and the ice element was in her hands, ever-changing. The two joined forces, and they were not inferior to the ice mage group of later generations.

The two huge ice wall dams built overnight not only greatly lifted the hearts of Shirley and Han Bing, allowing them to see the path of the ice mage's upward development, but also these two crystal-like dams, like a miracle, deeply shocked the hearts of every resident of White Fog Lake.

Inspired by this miracle, more than 3,000 residents are enthusiastic and work on Naga Island every day. In just one month, the construction of the main structure of a large-scale water prison has been completed. To say that the people on the Divine Grace Continent are still physically stronger than the earthlings. Such a project is the use of modern science and technology, and it is impossible to see results in half a year on the earth.

Thanks to the presence of the ice wall dam, the 3,000 residents completed the dam almost without water, closing from the foundation to the dam surface without any problems. Although the fog in Baiwu Lake is thick, the residents of the three towns of Baiwu Lake are already familiar with all this, and the buildings are not affected by the rich humidity during the construction of the dam.

Time really flies, and in the blink of an eye, it's September, and the temperature in White Fog Lake is even lower.

During this month, Manuel and the Banshee's research began to bear fruit, and the two discovered that there were three different types of water monsters in the White Fog Lake. This group of monsters can be divided into red-scaled monsters, blue-scaled monsters, and black-scaled monsters according to the color of their back scales.

Among them, the red-scaled monster has the strongest noise attack and low IQ, although this kind of monster has no research value, but the reproductive ability is very strong, the number is about 12,000.

The blue-scaled monster has mastered a certain amount of water spells, and has a high IQ, and the average fisherman is not their opponent, and the number of such water monsters is about 8,000.

The black-scaled water monster has the rarest amount of water, the highest IQ, and the strongest combat ability, but the number is only more than 1,000.

Before the laboratory released the research results, the fishermen in the three towns of Baiwu Lake did not have much understanding of this, and when they got the results, the fishermen verified them one after another, and found that the conclusions of the laboratory were indeed true.

In addition, Manuel discovered in an unexpected experiment that there was reproductive isolation between the three types of monsters, that is, the three monsters looked similar, but in fact they were different species. How to use the different bloodline characteristics of the three water monsters to cultivate a water monster with strong reproductive ability, high IQ and strong combat ability has become a new topic in the laboratory.

Alan was very excited about the results of such a study, and carefully told Manuel and the others about the little Naga that he occasionally learned about the little Naga in his previous life.

Excited to get the details, Marel continued to soak in the monster laboratory, where the tall animal trainer had almost turned into a fish-man these days.

While the dungeon was being built, Alan issued an order for the fishermen to use a sound device to drive the monster to the vicinity of Naga Island in preparation for filling the dungeon.

By the time the dam was completed, nearly 17,000 water monsters had been driven to the place, and they were screaming on the island every day, which made Captain Chock very upset.

However, this crazy leader is not useless, Jock is strong personally, and the black-scaled water monster that Manuel needs basically relies on this guy to capture.

Finally, one day in mid-September, the water prison was completed. Driven by the Ash Assassin, Captain Jock, Shirley, Ice, Druid and several other strong men, more than 10,000 water monsters were completely arrested on the day when the water dungeon officially entered the water!

It is worth mentioning that during this time, due to long-term immersion in the water, the circus druid sage actually learned the ability to transform seals, and since then he has become the leader of the water dungeon, with a group of second-generation black-scaled water monster powerhouses trained by Manuel and the banshee, completely ruled the water dungeon, and led the water monster every day to the White Fog Lake to catch the "fish that slipped through the net".
