"Princess, is the thing down there? Do you want Shuang'er to get the contents out? "Shuang'er is already a little eager to try.

"Don't be so troublesome, digging under the lake is too laborious and inconvenient, so let's clean the water first." Li Mu stretched out his right hand as he spoke, and a torrent of black elements rolled down, coming to the sky above the nameless lake like a black tornado.

The black tornado slowly touched the surface of the lake, and the rippling blue water melted as quickly as if it met the ice and snow of flames, and the originally clean lake water instantly became a free element and dissipated into the air, and the surrounding lake water replenished, and then continued this process.

In this way, the torrent of black elements descended rapidly, and the water level of the lake became lower and lower, until at last, slowly the pool of water evaporated, revealing the bottom full of silt.

Seeing this, Li Mu let the elemental torrent continue to consume the silt at the bottom of these lakes, but he was more careful and refined, as long as there was anything abnormal, he immediately stopped and looked carefully.

"Well, there's something." Li Mu's face showed joy, he casually dissipated the elemental torrent, and then used the mage's hand to remove the anomaly found by the elemental torrent. It was a silver nugget with a dime missing. This piece of silver has been sitting at the bottom of the lake for so long, it is still clean and shining, and if you look closely, there are many small spots on the surface of the silver nugget that emit a shining golden light, and these small spots emit a dazzling light, like stars floating in the silver night sky.

"Mithril!" Li Mu recognized the name of this kind of thing.

Mithril is a precious metal that is widely distributed throughout the universe. Because of its good magic transmission and malleability, it is widely used in various alchemical products and enchanted weapons, and is necessary for the construction of magic circles and many magical experiments.

Many magical worlds are built on the foundation of Mithril, and if they lose it, I'm afraid their civilization will collapse.

Although Mithril is very versatile and widely distributed, and can be found in almost all worlds where magical civilizations were born, this does not mean that Mithril is cheap.

On the contrary, due to its unique nature and non-renewable nature, Mithril has been classified as a strategic-level material in many worlds. As soon as the Mithril Mine is discovered, it will be immediately occupied, protected, and then sent to excavate and mine. A Mithril mine without a clear title can even lead to large-scale wars, even divine wars.

When Li Mu participated in the war against the kobold god with his team, the initial fuse was caused by a mythril mine that did not have a clear attribution. By the end of the war, one true god had died, three had been killed, one had disappeared, thirty-five bishop-level magicians had died, and nearly 100,000 soldiers had their blood spilled on the battlefield.

It was this tragic war that made Li Mu truly realize the value of Mithril. That's why Li Mu was so excited about digging out a silver nugget of Mithril.

There are one and two, and with the encouragement of the Mithril silver nuggets, Li Mu has been more meticulous in cleaning up the bottom of the lake. Pieces of Mithril were excavated, and layers of silt were turned into free elements. In the end, when the sun was about to set, Li Mu completely cleaned the bottom of the lake, and even dug two meters into the rock layer below and five meters around, and left here in a huff after making sure that nothing was missing.

After returning to the ship, Li Mu carefully counted the harvest. This time, he obtained a total of 227 Mithril Blocks, 12 Adamantite Gold Blocks, 366 diamonds and gems of various high purity, and a number of other magical materials.

Li Mu looked at these magic materials and smiled from ear to ear. As early as in the world of Double Star Story, he removed a lot of auto-attacking smoothbore cannons from the Oron Tower, which can automatically use the surrounding free elements to synthesize cannonballs, and then automatically search for targets and attack automatically. This is simply a combat weapon, if it is installed on a large-scale combat platform, then Li Mu's combat strength will immediately rise to a new level.

When the time comes, see who is not pleasing to the eye, more than a hundred smoothbore guns will shoot coveringly, and everyone below the silver will have to kneel. Of course, this is just thinking about it, there are two difficulties in the combat mission of sight, one is that these smoothbore guns themselves still have some defects, such as a slow rate of fire, a single type of ammunition, problems with the search mode, etc., which need to be adjusted and repaired by Li Mu himself one by one. However, there were not enough magic materials, so the project was put on hold, and now, with enough magic materials, this work has also been put on the agenda.

The second point is that there are no vehicles suitable for these weapons. In Li Mu's original idea, these things should be installed on the Floating City. He had long coveted the floating city of Goddess Mystra. But this kind of thing in the floating city is not something that he, a rookie who has no silver, can play.

Then he came up with the idea of using a floating battleship as a vehicle. Although the materials required for the Floating Battleship were much less than those for the Floating City, the key part of the Floating Stone came from a remote world, and it was not easy to obtain, so the plan was also shelved.

Later, Li Mu thought of using a goblin airship as a vehicle. However, the goblin airship was too slow, and the large balloon on top of the airship was too easy to target, so it had to be stopped.

After that, Li Mu thought of several plans, all of which failed with one factor or another.

In the end, it was the appearance of the White Bone Ghost Ship that gave Li Mu a new idea. He can load the weapon on the ghost ship and use it first, and then dismantle it when he finds a suitable vehicle.

Moreover, these automatic attack smoothbore guns also have several advantages, one is that they can save a lot of manpower, and after the smoothbore guns realize automatic attack, the gunner profession can be completely removed on Li Mu's ship. Moreover, these smoothbore guns will also be more accurate than humans and have fewer errors. In addition, since these smoothbore guns use free energy to form shells for attack, the space originally used to hold gunpowder and shells can be freed up for other things, so the combat effectiveness is greatly increased. Finally, these smoothbore cannons can generate energy shells with various effects, and they can attack various special targets without sticking to ordinary cast iron shells, and their lethality will be higher than that of ordinary cast iron shells.

Now, Li Mu has the magic materials, and it only takes some time to improve those smoothbore cannons that attack automatically, and all he has to do now is to quickly find the clues of the Bone Ghost, and then get the Bone Ghost before everyone else, and then, drive out these involved players one by one......
