The next morning, as a famous natural wonder in Mingjing City and one of Luo Ji's fortune capitals, Mingjing Lake was directly reserved by the Ordnance Research Department today.

There is no way. If they want to test underwater weapons, they must look at the performance under water, but they can't go to the Yangtze River port to do this weapon test.

Considering the issue of convenience, Mingjing Lake is the closest test site to them as long as it meets the test requirements.

For safety reasons, all the fishing boats on the lake were cleared. At the same time, a long isolation line was set up around the entire perimeter. The formation was quite large.

Fortunately, it is not the peak fishing season now, so it will not have much impact on their fishing industry in Minjing City.

"Yexuan (Karl), please see Your Majesty."

After getting off the car, looking at the two people in front of him, Luo Ji couldn't help but have a flash of surprise in his eyes.

"Karl, why are you here?"

Karl was the top elf craftsman among the high elves, and all of Luo Ji's magic equipment was forged by him himself.

However, Luo Ji was obviously surprised to see Karl here, and at the same time, some speculation inevitably arose in his heart.

As a result, before he could think about it further, Xuan Ye had already said the answer with a smile.

It turns out that this time, the underwater weapon research and development project Luo Ji ordered for Ye Xuan was to be used to deal with the fishmen. The soldiers of the fishmen were generally huge in size. They were everywhere at the level of two to three meters, and those below ten meters could be seen everywhere.

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

Under this premise, the underwater weapons that Xuan Ye developed several times failed to meet her expectations in terms of power, which forced her to overthrow and redo them over and over again, or even change her thinking and redesign them.

However, in this era, due to the limitations of technical and technological capabilities, it is really difficult to create underwater weapons. Even top talents like Ye Xuan are stuck in a bottleneck and don't know where to start.

The feeling of getting started together.

At this time, the special features of their All Worlds Civilization were revealed. They were not an ordinary human civilization at all. Within the All Worlds Civilization, they had too many things that ordinary human civilizations did not have.

In this way, Ye Xuan, who was stuck in a bottleneck, had an idea to improve the power of weapons as a breakthrough. She directly thought of the magic weapons of the elves.

Although the weapons of the elves are all typical cold weapons, who dares to say that they are not powerful?

The bursting arrow shot over was no less powerful than a high-explosive grenade.

Earlier, when Luo Ji asked Ye Xuan to devote all her efforts to developing underwater weapons, he also gave her a warrant. Whether she wanted money or people, to a certain extent, she could be mobilized directly with this warrant.

Now that it's all right, Ye Xuan, suddenly inspired, took the warrant and took the elf craftsman Karl to the Ordnance Research Department. You can imagine what happened next.

"So, you guys worked together to create a magic weapon?"

When Luo Ji said this, his expression was extremely subtle.

It has been said a long time ago that there are basically only two ways to forge magic weapons.

The first method is to use the spirit wood specially cultivated by the elves. The magicians’ staffs and the shafts of the elves’ magic arrows are all made of this spirit wood.

According to the difference in the age of the spiritual wood, there is also a huge gap in the value. The most valuable spiritual wood at present naturally comes from the ancient elven tree, which is a top-notch material in the true sense.

In addition, another way is to incorporate a rare magic material into the forging material, which is the three-star natural wonder of their civilization of all worlds and one of the specialties of Xingchen Lake, star sand!

Only after the star sand is incorporated can the properties of the material be changed, thereby engraving incantations and forming spell blessings.

But now the problem comes, those are rare magic materials!

Star Lake is only so big, and the amount of star sand at the bottom is even smaller. Only by bathing in the light of stars for many years can some star sand be gradually produced. There is no shortcut at all.

Judging from the current situation, this underwater weapon is definitely not made of spiritual wood. It is okay to use it as a staff and arrow shaft, but it is purely overthinking to use it as other weapons.

In this way, the only thing that can be used is star sand. In addition, in order to run the spells on the weapons, magic crystals must be used as energy sources...

Combining various factors, an answer has emerged in Luo Ji's mind, that is, this weapon is destined to be unable to be mass-produced, and it is also extremely expensive!

In a war, how useful can a weapon that cannot be mass-produced be used? Unless it can reach strategic level, but this is obviously impossible.

At this moment, it can be said that more than half of the anticipation in Luo Ji's heart was gone.

But anyway, let’s take a look at the finished product before drawing any conclusions.

As soon as her thoughts were whirling, Xuan Ye had already taken out her newly developed weapon.

The size is unexpectedly small. The appearance is similar to that of a gun, but it is much larger than an ordinary rifle. It can be used as a rocket launcher when carried on the shoulder. Obviously, the reason why there is such a size is that there is a lot inside.

The main reason is to increase the attack power.

The aqua blue gem inlaid at the end of the barrel made Luo Ji clearly realize that this indeed required consuming magic crystals.

At the same time, the large number of spells and incantations surrounding the water magic crystal clearly told everyone that this was a magic weapon that incorporated the elves' incantation technology.

After looking at the main body of this weapon, which was definitely not cheap, Luo Ji's eyes quickly shifted to the two objects next to it.

One is a can that looks suspiciously like an oxygen bottle. I don’t know what it is used for, and I can’t tell what its characteristics are.

The other one looks like an arrow, but it is much larger than the arrow. At the same time, it is completely made of metal. The arrow with four corners unfolds and reflects the cold light in the sun, making it look like an arrow.

Extremely ferocious.

Moreover, the sharp-eyed Luo Ji could see at a glance that every edge of the arrow had obvious blood-letting grooves on both sides. It was clear that it was based on the design of their early blood-letting guns and combined with the current advanced technology.

A further improvement is a weapon specially designed to deal with large enemy units with rough skin and thick flesh.

After reading all three of these things, Luo Ji suddenly had thoughts.

"Is this a harpoon gun?"
