However, this was just the beginning, and soon some other teams found the same mana crystal in the depths of some caves, and after identification, it was confirmed that it was from the same source as the first mana crystal that was discovered.

In the next two days, more magic crystal caves were found, and finally according to the total, the total number of caves actually reached an astonishing more than 100, and the distribution of these caves is not concentrated in one place, but far and near, but it is precisely because of this that Wang Fan will also be attracted by it, because the magic crystals of these caves are completely the products of the same source, which means that these more than 100 caves are actually natural caves of this magic crystal mine with unknown reserves at the bottom of the sea.

And according to the distance between its easternmost mine and the westernmost mine, as well as the southernmost and northernmost simultaneous calculations, the coverage of this magic crystal mine has reached an astonishing more than 2,000 square kilometers, and according to the system's scanning, its reserves are also about 250 million tons. You must know that the reserves of Sijiaying Iron Mine, the largest mined iron ore in China, are as high as 2.348 billion tons, and the reserves of the unmined Benxi Dayaigou Iron Mine have reached a prospective resource of 7.601 billion tons!)

Therefore, whether it is for the sake of war readiness energy or the consideration of the future economy, Wang Fan is absolutely imperative to this water system magic crystal mine, even if there is a demigod in front of him, then he will restart the undead base and use the gold coins stored during this time to kill the other party to take this magic crystal mine, after all, gold coins are honestly not valuable in this universe, because there are countless planes here, maybe some planes gold resources are really scarce, but there are also some planes where gold resources may be everywhere。

Just like the earth element plane and the water element plane, the plane where the metallic energy is concentrated is really likely to be the real gold mountain and silver sea environment, so the value of gold is not stable, some planes can be used as a universal currency in the plane, while some planes are just some beautiful stones on the side of the road.

Therefore, for the sake of his own future, Wang Fan must hold enough hard currency, and the magic crystal is naturally the first choice, because this is a magical world, and magic and fighting spirit will definitely be the absolute mainstream in the future, because the driving force behind all this is the will of the great universe, which will slowly erase discordant things with endless time, and then greatly promote magic, which can also be conducive to the evolution of the universe.

It is precisely because of this that Wang Fan wants to store a large number of magic crystals for the future, don't forget that Wang Fan is not alone, although the number of elves under his command is very small now, but now with Wang Fan's protection and the shroud of the tree of life, the future is already full of light, and the children of the elves will definitely be born in batches in the future, plus there must be other elf tribes in other places that have not been conquered by Wang Fan, so the currency of the elves' subordinates in the future, Equipment and so on are big problems, and magic crystals can help Wang Fan solve these problems very well.

So Wang Fan made a move, he transferred back most of the Earth Elemental Legion that was still hunting, and began to go directly to the Wailing Gate of the swamp plane through the dark gate at the bottom of the mage tower, and then boarded the ghost ship that had been waiting for a long time and drove to the shallow sea area.

Obviously, the earth system restrains the water system, so when the earth elementals came to the hole in the shallow sea with the ship, the earth elemental legion jumped directly off the boat and fell towards the hole below.

But first of all, what the stone giants do is not to enter the cave, but to expand the cave, there is no way, because the entrance of the cave is too small! The stone giant's height of 7-8 meters can't pass through at all, so the hole must be expanded! (The ghost ship can be turned into a ghost form, so regardless of the size of the cave entrance, but the attack power in the ghost form is almost zero)

It is worthy of being the most violent demolition brigade under Wang Fan, and it took less than 10 seconds for the stone giants to successfully turn the entrance of the cave from the original less than 10 meters directly into a 100-meter giant hole, of course, this is also thanks to the fact that the rock giants are all earth elemental lifeforms, otherwise even if they can be demolished, it is only equivalent to twice the destructive power of the meat grinder.

Soon more rock giants also jumped off the ghost ship that followed, and then jumped directly into the extremely deep cave, don't look at it in the shallow sea, but it doesn't mean that the cave is also shallow, the speed of the ghosts was fast before, it was completely because they were in the ocean, so they were blessed, plus their own characteristics of ignoring small obstacles, so they could reach it quickly, and now they changed to rock giants, the result was naturally different, it took more than half an hour to bump all the way, and the rock giants went down to the bottom of the cave, more than 2000 meters below the sea level in the ultra-deep crypt。

As soon as they landed, these rock giants immediately followed the sea ghosts who came to lead the way and went directly to the mining cave they had assigned, and at the same time entered a large number of ghost ships, which will take on the task of transporting the magic crystals dug up by the rock giants directly to the shore with the ghost boats, and this is another reason why the cave needs to be opened, after all, after transporting the ore, the ghost ships cannot be ghosted, otherwise there will be only one consequence, that is, all the magic crystals will leak directly from the ship！

Therefore, Wang Fan ordered the rock giant of the first ship to stay at the mouth of the cave and open the mouth of the cave, otherwise when the amount of mining is large in the future, it will not be the same to expand the cave entrance, so it is better to directly open the cave mouth now!

And don't worry about the expansion of the cave after the sea water pours in and floods the mine, after all, the things in the mine are all water-attribute magic crystals!

But now these noble water elements are about to suffer, because it has encountered Wang Fan, a greedy guy, so the fate of being mined and used, they are already in a catastrophe!
