Killing and injuring fishmen with flying swords may be very efficient, but it is always impossible to get the almost infinite number of fishmen, killing more, coming more, and killing inexhaustible.

And when it comes to boosting morale, it's probably not as good as Alberke's freezing spell!

After all, it's a large-scale magic effect that can be witnessed by the soldiers below, and the flying sword kills the enemy, which is efficient and stealthy enough, but it's just not obvious enough-

The kind of obviousness that makes ordinary people feel exaggerated!

After thinking about it, Xia Duo took out a fireball wand from his personal space, and when the subsequent fish-man emerged from the water to the north and tried to climb onto the ice, he slammed it out.

A fiery orb of flame no larger than a human eyeball appeared on the tip of the wand, and flew towards the big fish's head with a low buzzing sound.

If it's used by a non-master, it probably depends on each person's aiming skills, but when a wand is used in a mage's hand, especially in the hands of an arcane artist like Xia Duo, it is still possible to modify the spell's effective path less than that.

No, the blazing flame bead hit the fishman's head accurately, and then a large cloud of almost incandescent flames erupted, and the fishman's head was burned out in an instant.

And the effect of this spell was far more than that, the large cloud of incandescent flames continued to spread, affecting the entire river channel more than ten meters wide.

Immediately afterward, a large cloud of dense water vapor rose, and even a piece of the ice that Alberk had created on the surface of the river was missing.

The other fishmen in the vicinity of the fish-men who were directly hit by the fireball spell were not doing well, and they might have remained intact, but the big head was all charred black.

Seeing that it didn't move, it was dragged underwater by the surviving fish-people further behind.

With one fireball technique, he only killed four or five fishmen, Xia Duo saw it in his eyes and felt pain in his heart, but fortunately, this wand was not prepared by himself, but the combat materials issued by the Seven Towers when he was in the green field plane.

When he and Nia left the Plane of Oz, the Resonance Spellbook was taken away, but the wand, scroll, and even the battle robe, which resembled an elven sword suit, were left with them.

Wands are all disposable items, and the shelf life is far inferior to ordinary magic items, and Xia Duo will not have many opportunities to use his wand in the future, if it weren't for this special situation, he would even have kept this wand until its expiration date.

The true value of a wand lies in the concentration of a large number of spells to achieve a specific purpose.

Now, for example, if Xia Duo is super rich and has purchased a large number of wands, he can give them to soldiers who can use magic items to clean up the fish-people with their wands.

But obviously, Xia Duo doesn't have so much money, he can use it himself, and distribute it in large quantities, so he has more than enough energy to do it.

……

Next, Xia Duo fired more than a dozen fireballs one after another, each of which could attract the cheers of the soldiers in unison, and the dense fireball explosion even evaporated the Wolfburg River for a time.

A large area of water vapor met the cold air above, and a drizzle with very little coverage fell on this battlefield area.

As for the fish-men, during this period, it is naturally impossible to launch any effective attacks.

It wasn't until he used up all the spells stored in his wand that Xia Duo stopped, and his morale was indeed up, but the money was also used up.

As for the actual results, they are almost negligible, and they seem to have killed a lot, but with the continuous replenishment of fishmen in the north, it is no different from not killing one.

Just like Xia Duo said to O'Boline before, there must be a reason why these fish-people are endless, and only by understanding the reasons can we really get in touch with the crisis of the fish-man crowd.

Whatever the reason, if it's really a lot of it, then kill until it's scarce, and if there's something that is constantly creating fishmen, then destroy the source.

Xia Duo still knows about the situation of the Mehet River, although it is the fishman farm of the Mingshui Chamber of Commerce, it is impossible for there to be so many fishmen that can actually accommodate it.

It is impossible for the entire Wolfburg River to sustain such a large number of fishmen.

Therefore, Xia Duo guessed that there must be a source that was constantly creating fish people, otherwise it is really difficult to explain this phenomenon of fish people all over the river, densely packed like canned sardines.

Fortunately, although this fish-man is an amphibian, it is more inclined to be aquatic and cannot leave the water source for a long time, if it is like a lizard and can run around, then this problem is too big.

Maybe it's another goblin in the shape of a fish.

Thinking about the manpower and financial resources that Savile Town spends every year on cleaning up the goblins, Xia Duo has a headache, and the territorial guards of the Savile Territory can almost be said to be born to clean up the goblins.

As long as it is not cleaned up for a while, it is easy to overflow, and even if it is cleaned up regularly like it is now, and at the same time the adventurer quest is issued for adventurers to clean up, it still does not kill the goblins.

Xia Duo realizes that even if the crisis of the fish-man crowd is solved, there may be a kind of fish-man mob in the south and even in the color-resistant territory connected by the Wolfburg River!

It's like a goblin, although it may not be able to cause much damage, but who will pay for the cost of governance!

Thinking about it this way, this Mingshui Chamber of Commerce is really evil!

Where to raise fish is not good, you have to get the main plane, and you still raise it in your own country, it's okay if you don't have an accident, but when something happens, it will be infinitely poisonous.

Of course, the Great Arcanist of Horn, the source of the fish farmers of the Mingshui Chamber of Commerce, the Great Arcanist of Kieran Tower, also bears some responsibility!

It's a pity that whether it's the Mingshui Chamber of Commerce or the Great Arcanist of Horn, Xia Duo can't afford to provoke them, let alone force them to pay compensation.

They can only be regarded as common victims, turning the spearhead to the common enemy, which is also the most direct culprit in this matter, and it is obvious that Xia Duo does not make any other conjectures except for the elves.

The fishmen in Lake Mehmet may have escaped the control of the Bright Water Chamber of Commerce, but the previous time Shado passed through Lake Mehmet was shortly after the snowmelt race.

At that time, although the fish-man had already shown signs of getting out of control, he was quickly dealt with by the Mingshui Chamber of Commerce.

It had been less than a year since that incident, how could those fish-men have given birth so naturally for no reason, so much so that the stretch of the river from Lake Mecht to Savile had been filled!

There must be an outside force interfering!

And the external power, there is almost only one elf, except for the elves, who dares to provoke a great arcanist of the Seven Towers in the territory of Nethril!

These fish people were directly raised by the Mingshui Chamber of Commerce, but in the final analysis, they were raised by Horn, and when this happened, Xia Duo didn't believe that Horn really didn't have any emotions at all.

……

At this time, Nya's perception field of exploring spells finally arrived at Lake Mecht, and the perception information was also received by Xia Duo through the psychic link.

He substituted his perception into Nia's point of view, and in an instant, he "saw" Lake Mecht as it looked, nay, more precisely, not as it looked like Lake Mecht.

Because, today, the whole of Lake Mecht is shrouded in a strange green light!

This green light is not like normal colored light, even if it interferes with the line of sight, it can still penetrate, this green light is more like glow and fog.

It can't help but interfere with normal vision, and even interfere with magical vision, making it difficult to discover the secrets inside.
