During this period, the fish-man troops sent by William Mousse were not polite to them at all, and pursued and fought fiercely all the way, and beat this foreign combined fleet back.

Now, on the side of the East China Waiwai Sea, the forces on the side of foreign players have completely fallen into a state of passive defense.

Several foreign players who were desperate frequently sent letters to Xia Qiqi, explaining the stakes and asking him to send troops to support.

After reading the content of the letter, Xia Qi, who was discussing military affairs in the Yiwu Hall at the time, casually handed the letter to Zhang Liang below, he wanted to hear the other party's opinion.

Originally, according to Xia Qi's expectations, there was a combined fleet of four foreign players in the sea area east of Great Xia, and with the weapon of depth charges, how could they fight with the other side for a few more years, and even have a chance to lose both.

But it turned out that he seemed to be thinking a little too beautiful, and he didn't know if it was because the fish-man troops in that area were too powerful, or if the sea fleet of the four foreign players was not as strong as before after the early years of attack.

The gap between the two sides widened all of a sudden.

"Your Majesty, taking the initiative to get involved in this naval war in the outer seas will also be a big risk for us in Great Xia. However, looking at the momentum of the other party's fish-man troops, once they have completely captured the outer seas, then the next step is probably to reach out to the East China Sea of our Great Xia. ”

Speaking of this, Zhang Liang breathed a sigh of relief, and then spoke again: "Therefore, according to Wei Chen's opinion, since both horizontal and vertical are going to fight, it is better to take advantage of the fact that the foreign combined fleet still has a little resistance to temporarily join forces with them to fight the enemy, which is more or less a combat force." ”

After listening to Zhang Liang's opinion, Xia Qi nodded slightly, and the thoughts of the two could be said to coincide.

Although he had only sent a fleet before, Xia Qi, who had been building warships to develop naval combat power over the years, had already accumulated quite a strong naval force in his hands.

Now, even if Tang Han is not there, he still has Lu Meng's East China Sea Fleet and the Xia Hai Fleet in his hands that can be used.

The only scruple is that the scale of the Fish-Man Force in the East China Waiwai Sea is not small, once the fight starts, for the time being, although he has also built a number of specially equipped with special depth charges to deal with those Fish-Man units.

But the odds of winning, Xia Qi can still only be said to be five or five.

Suddenly, Xia Qi couldn't help but think of what he had ordered in his early years.

"I wonder how the underwater weapons research is going on at the Ordnance Research Department?"

With this in mind, Xia Qi asked Hu Yitong and Du Ruhui, "Is there a report sent over to the Ordnance Research Department?" ”

Hearing this, the two assistant officers who were sorting out the documents and reports there really couldn't answer for a while.

Because the secretary's office had just delivered the afternoon's papers, they hadn't had time to read them yet.

didn't have time to think about it, and the two assistants hurriedly started work.

After getting acquainted with the administrative work of the service hall and the secretary's office, it is actually very simple to find the documents of a certain department.

First of all, in order to make it easier to distinguish, the folders used by each department are of different colors, but even so, there are still dozens of large and small departments in Daxia, which leads to insufficient colors.

Therefore, under the premise of establishing color distinction, there are often special marks of various departments, and newcomers who are not familiar with these colors and marks may be directly confused.

However, after three or four months of work, it will be found that this way of distinguishing is really very convenient.

I saw that after Du Ruhui glanced at it, he found the folder belonging to the Ordnance Research Department from the large pile of documents, and then handed it to Xia Qi's eyes.

Xia Qi took the document and began to look through it quickly, with a faint expectation in his heart.

If the Ordnance Research Department can develop a powerful enough underwater weapon, they will have a better chance of winning the battle against the Fish-People in the future.

And this document, as Xia Qi expected, is indeed a report document on the completion of the research and development of new weapons! It was the weapon project he had instructed Xia Fox to develop before.

Early the next morning, a vast area of Daxia Lake was separated by a fleet.

If they want to test underwater weapons, they must look at their performance underwater, but they can't go to the East China Sea or the Xia Sea.

Considering the convenience problem, if the test requirements are met, this Daxia Lake is the closest test site to them.

"Summer Fox (Boudreau), see Your Majesty."

After getting out of the car, looking at the two people in front of him, a trace of surprise flashed in Xia Qi's eyes.

"Boudreau, why are you here?"

Budro is the top elven craftsman in the High Elf clan, and many of the spell equipment of the generals of Great Xia were forged by him himself.

However, seeing Budero here made Xia Qi have some surprises.

Before he could think about it, Xia Fox had already said the answer.

It turned out that this time, the underwater weapon research and development project that Xia Qi ordered to give Xia Fox was to be used to deal with the Fish-Man Clan, and the physique of the Fish-Man Clan soldiers was generally huge, two or three meters were everywhere, and they could be seen everywhere below ten meters.

In this way, there are naturally quite strict requirements for the power of underwater weapons.

Xia Fox has developed underwater weapons several times, but the power has not met her expectations, which makes her have to tear down and redo it over and over again, and even change her thinking and redesign.

However, in this era, due to the limitations of technology and scientific and technological power, it is really difficult to get an underwater weapon, and even a top talent like Xia Fox has a feeling of being stuck in a bottleneck and not knowing where to start.

At this time, the special features of Great Xia were revealed, they were not an ordinary human civilization at all, and there were many things that ordinary human civilizations did not have.

As a result, Xia Fox, who was stuck in a bottleneck, had an idea, and took increasing the power of the weapon as a breakthrough, and she directly thought of the magic weapon of the elf clan.

Although the weapons of the elves are all typical cold weapons, this cannot deny their power.

Earlier, when Xia Qi asked Xia Fox to develop underwater weapons with all his might, he directly gave her a warrant, whether it was money or people, to a certain extent, with this warrant, she could be directly mobilized.

Xia Fox, who was inspired all of a sudden, directly took the warrant and put the elf craftsman Budro in the Ordnance Research Department, and the rest of the matter can be imagined.

"So, you guys teamed up to make a spell weapon?"

When Xia Qi said this, the expression on his face was also a little subtle.

As I said before, there are basically only two ways to forge a spell weapon.

The first method is to use the spirit wood specially cultivated by the elf clan, and the magic staff of the mages and the arrow shafts of the elf magic arrows are all made of this spirit wood.

According to the difference in the age of the spirit wood, there is also a huge gap in the value, and the current highest value of the spirit wood is naturally from the elf ancient tree, which is the top material in the real sense.

In addition, the other way is to have to incorporate a rare spell material into the forged material.

But here's the problem, these are rare spell materials!

And judging from the current situation, this underwater weapon must not be made of spirit wood, that thing is okay for magic staff and arrow shafts, but it is purely too much to think about it when it is used for other weapons.

In addition, in order for the spells on the weapon to work, it is necessary to use the magic crystal as an energy source.

After the combination of various factors, an answer has already surfaced in Xia Qi's mind, that is, this weapon is destined to be impossible to mass-produce, and it is expensive to death. In a war, weapons that cannot be mass-produced are not of much use at all, unless they are fought at the strategic level.

It can be said that the sense of expectation in Xia Qi's heart has disappeared all of a sudden.

Well, but anyway, let's take a look at the finished product before jumping to conclusions.

On the other side, Xia Fox had already taken out his newly developed weapon.

The new weapon resembles a gun, but it's much larger, and it looks like a bazooka on the shoulder.

Obviously, the reason why there is such a size, a large part of them are willing, is to increase the power of the attack.

And the aqua blue gem inlaid at the end of the barrel made Xia Qi realize that this weapon did need to consume magic crystals.

At the same time, the large number of spells depicted around the water magic crystal also clearly told everyone that this was a spell weapon that integrated the spell technology of the elf race.

After looking at the main body of this weapon, which was absolutely impossible to be low, Xia Qi's eyes quickly shifted to the two objects next to him.

One is a canister that looks like an oxygen cylinder, but I don't know what it's used for, and I can't see any characteristics for a while.

And the other, looking at the shape, looks like an arrow, but it is much larger than the arrow, and at the same time, it is completely metallic, and the arrow with four edges and corners is unfolded, reflecting the cold light in the sun, which looks particularly hideous.

Moreover, the sharp-eyed Xia Qi could see at a glance that each edge and corner of the arrow had obvious bloodletting grooves on both sides, which clearly referred to the design of the bloodletting gun in the early years of Great Xia, and combined with the current advanced technology, it was further improved, and it was a weapon specially used to deal with large enemy units with rough skin and thick flesh.

After reading all three things, Xia Qi suddenly had a thought.

"It's ...... Harpoon guns? ”

In this era, it is simply impossible for ordinary firearm-type thermal weapons to be used underwater, and they will directly mute fire.

But the harpoon gun is different, it is said that it is a gun, but in fact, this weapon does not use gunpowder at all.

Sweeping his gaze over the tank that seemed to be like an oxygen tank, Xia Qi probably already knew how this thing worked.

Regarding Xia Qi's name of "harpoon gun", Xia Fox, who was standing on the side, looked thoughtful.

It was obviously a first-time word for her, but the harpoon gun was a fitting name.

Thus, this latest weapon was named.

After entering the actual operation link, in order to see clearly, Xia Qi naturally wanted to follow them and dive into Daxia Lake.

For this purpose, the people of the Ordnance Research Department have long prepared oxygen tanks and diving suits.

Although these devices had been built many years ago, Xia Qi wore them for the first time, and they were a little more cumbersome than expected.

It is not easy for normal humans to dive into the sea in this body, and it is not easy to do some simple underwater work, and it is really a bit difficult to expect them to be able to fight underwater.

As such, the person in charge of operating the Harpoon Gun underwater is a soldier from the Lizardmen's underwater combat unit.

Wearing a special combat uniform, the full set of equipment for the harpoon gun had been put on, and after making all the preparations, everyone, including Xia Qi, dived into the water one after another.

In order to ensure the safety of His Majesty the Emperor, the people of the Ordnance Research Department also specially found two lizardmen soldiers to protect them, one on the left and one on the right.

To be honest, this battle seemed to Xia Qi to be a bit of a fuss.

It's not that he can't swim, let alone drown while wearing a wetsuit and carrying an oxygen tank?

After complaining a few words in his heart, Xia Qi, who was too lazy to continue to entangle, quickly shifted his attention to the scenery under the surface of the lake.
