That's right, after the confirmation of the soldiers and some experts, Chi Nan finally discovered the most precious things in the northern land, which are those minerals. Minerals that are almost useless to bugs, but useful to humans.

Although the north is barren, iron ore and copper mines are everywhere, which is really unexpected.

Although the territory does not need so many minerals for the time being, it is also very necessary to survey them first, or even mine them and store them. Anyway, there is no one in the north, and their own plants are managed.

Even if they are all stored, as long as they are not put into the market, it will not cause market turmoil.

Nowadays, there is not only one type of iron bark tree, and it is not only a magnet that absorbs iron ore. After the research of those who have the authority, there is now a special ironbark tree that can absorb various abilities such as copper, gold, silver, etc.

Even if the metal is not very powerful, it is good to just absorb and condense the metal.

Moreover, in this place in the north, two super-large magic crystal veins were actually discovered. This magic crystal vein has never had any effect on Chinan, but it has an incomparably huge effect on humans, far more than any other mineral.

Whether it's an alchemical cannon, or a flying boat, or other alchemical weapons. Even the mage's cultivation experiment, the energy source of the mage tower, etc., basically all require the participation of the magic crystal mine.

Especially for the Holy Dragon Empire, the demand for magic crystal ore is even more than ordinary people imagine.

In the past, the place where he was located was barren, and none of the nearby kingdoms had magic crystal mines. But Chi Nan himself didn't expect that the north would find two of them at once, which were still super-large veins.

"This place must not be leaked out, otherwise both the Holy Light Empire and the Holy Dragon Empire will come and attack. ”

Looking at the map, the location of the ore veins was closer, one was closer to the Holy Dragon Empire, and the other was actually closer to the Holy Light Empire. It was a wasteland in the north, and it had never had an owner.

Although whoever is defeated is whoever, but when it comes to such a big benefit, even the empire may not abide by the rules. Isn't it very normal to find some excuse to attack yourself?

Therefore, mining must not use people, and Chinan can only design several special plants specially used for mining, so as to mine magic crystal ore. As for selling this kind of thing, Chi Nan decided to change his name and sell it to the half-elf empire through the half-elf royal family. In his own right, the Half-Elf Empire is the least dangerous to himself.

Moreover, although the Half-Elf Empire also needed a large amount of magic crystal ore, it was not as urgently needed as the Holy Dragon Empire.

Sell some in small quantities and won't cause trouble. The rest will wait for the mages and alchemists in their own territory to develop. There are a large number of magic crystal mines, and the strength of the puppets will also be improved.

The battle in the north is over, but further north in the north, some bugs still escape. Every day, a large number of plant weapons are under the control of the soldiers, constantly spreading and searching towards the far north.

The closer you get to the north, the more cold it gets, and it's hard for bugs to get underground. Plant weapons want to go deeper, again, it is not an easy task. Only then did Chi Nan realize that his plant weapons were still afraid of the cold.

It's not that you're really afraid of cold, it's that the cold will make your plant weapons less active. To this end, the soldiers took the initiative to find various plants in the cold zone to extract and fuse, and added a cold-resistant property to their plant weapons.

It wasn't until late spring that this cold-resistant plant weapon appeared in abundance and completely conquered the Far North.

It's just that at this time, Chi Nan once again saw something incredible. Because Chi Nan found that this land was not what he thought, he originally thought that if he reached the far north and continued to walk, he would move towards the south.

After all, the earth is like this, isn't it the case with all planets? However, the report I saw this time made Chi Nan fully realize that this world is definitely not as simple as he knows.

"The north actually encountered a special layer of spatial turbulence, tiled in the far north. As long as everything that enters this place will be devoured by corrosion, and nothing will come back at all. ”

Chi Nan looked at the report as if he were reading a myth. "The most terrible thing is that the edge of this special layer of spatial turbulence is roughly a straight line, no, it should be said to be a plane. This shows that the extreme north is not a point, but a line. The tests are completely different from what I know. ”

Until now, Chi Nan is still a little unbelievable, isn't this world a ball, isn't this piece of earth under his feet a spherical shape, isn't this the existence of a round sphere.

Yes, there are gods in this world, and if the earth under your feet is really spherical, then those gods will definitely be able to see it when they leave this land, and they will not fail to tell their own believers.

There is no reason why every god would do the same deception, it is absolutely impossible. Even if it is for the sake of faith, the gods are not the same as the gods, is it possible that if one god deceives the believers, the other gods will not use the facts to attack the opponents? The struggle for faith has always been the most brutal.

So there is only one truth, that is, the land under your feet is actually a flat, or roughly a flat, at least not a ball, what kind of world is this?

Chi Nan has a sense of déjà vu that the worldview has collapsed, and he has been sitting in this place, silently thinking about life.

This state of affairs lasted for three days, until the guards retrieved the information that Chi Nan wanted.

Looking at these theological materials, Chi Nan finally found something useful in the middle. The term "plane" is used for different worlds, not the concept of planets.

It is possible to reach other planes through special methods, but it has always been that there are limits to the north, south, east and west, and at least in the recorded world, none of them are spherical. I don't know if it's because the laws of this world are different, or if there are other reasons.

But Chi Nan, who is not qualified to explore, can only accept this strange setting in the end. "Okay, it's flat, it's flat, it doesn't matter anyway, just continue to develop my own plants. ”

Chi Nan, who had been worried for a long time, decided to gather all his wives and vent well. Although no one knows what Chi Nan is worried about, he has been distressed for a long time, hasn't he?
