This can be regarded as a hidden benefit of the underworld, after all, many times, although the undead invade the invincible, but the casualties are still very serious, especially in the early days of the war, so it is impossible to directly send millions of troops in the past to stabilize the situation at one time, so the casualties of the vanguard troops are often the largest, even if the personnel are replenished afterwards, it will still cause a lot of impact, and the main reason for this is the geographical relationship. The www.biquge.info is completely unfamiliar with the surrounding environmental factors, so it is very passive.

But now with the support of the power of the underworld, it can easily corrode a plane like the abyss, and then turn the passive geographical advantage into the advantageous geographical advantage of its own side, so that at least the environment is not familiar with this point is solved, after all, the corrosion of the underworld and the abyss are generally the same, they are all corrosions that will change the terrain in a large area, just like wind and rain eroding the rocks of the mountains, the death breath of the underworld and the evil power of the abyss are all good hands in this regard, and even the divine light energy of the heavenly realm and the dark elements of the dark realm have such power, but in terms of transforming the environment, they are not as good as the first two。

Therefore, as long as the invasion of the underworld begins, if you can't completely repel the invading undead and come up with a way to curb the spread of pollution in the underworld, then as long as you wait for more than ten years of effort, with the powerful power of the god-level main plane level of the underworld, wouldn't it be easy and pleasant to corrode such a plane that is just enough to enter the main plane level!

, But obviously, Wang Fan doesn't plan to wait, although in the end, as long as he is patient enough, then even the fish people in the plane after the undead words will not be able to survive, so even if they kill each other, they will not be able to get rid of the fate of extinction in the end, just like a strong man who can destroy a planet with one punch, but he still needs to breathe, he doesn't dare to use all his strength at all, otherwise he himself will have to suffocate in the universe void, and the same is true for the fish man, if he loses the protection of the plane, then naturally even if he has the fertility to coax him, it will be in vain！

Because Wang Fan's real purpose is not to destroy the fishmen in this world, on the contrary, Wang Fan needs to use these fishmen to train his troops, and after a long time of reconnaissance, this place is indeed worthy of being the feng shui treasure found by the dehydrated fishmen who have been excluded after experiencing countless deaths and injuries, not to mention, the entire area is easy to defend and difficult to attack, not to mention, there is only one entrance, and although the fishmen can dig the mountains, but this trick, Wang Fan has already thought about it, after all, he himself often does this kind of thing, so a strong forbidden magic will be set near this valley, and it will also be at the foot of the mountain, a large number of goblin bombs and goblin mines are planted at the mouth of the valley, so that if the enemy dares to carry out earthwork, then teach them to be human in minutes!

But this is not enough, so after the start of the invasion, with the slaughter of the dehydrated fish-man village, the engineer troops of the sixth invading front army also arrived here, if it is a formal large-scale war, then now it will definitely not be to transmit these engineering troops with combat effectiveness, but now the dehydrated fish-man tribe, to be honest, the real engineering troops can blow them up, there is no way, the gap between the two sides is there!

It's like the logistics troops of the U.S. imperialists, even if the combat effectiveness of these guys is still hanging to fight the African black uncle, and Wang Fan's side is the same, if he bullies a dehydrated fish-man tribe, even if it is the plane breeding front army with the worst combat effectiveness in the forces of the undead legion, in fact, it is the kind of existence that belongs to the undead places, armed forces, and police, and can also be hung to fight this tribe.

The reason why the Ghost Knights came up first is not how awesome the Dehydrated Fishman Tribe is, in fact, the strength of the entire Dehydrated Fishman Tribe is only the strongest at the Sanctuary level, and the Ghost Cavalry Regiment is the most elite unit of the Sixth Plane Invading Front, and it is the core of the entire Sixth Plane Invading Front, so every member has a Sanctuary level immediately, and it can be said that it is not much worse than the Black Blade Knights of the elite front in terms of quality.

Of course, there is no comparison in terms of quantity, after all, although the Black Blade Knights are also knights, the number of members is close to 100,000, it is a knight called the knights, which is actually a knight legion, and the ghost knights are real knights, with more than 10,000 people!

The reason why such a luxurious ghost knight is used to deal with such a rookie dehydrated fishman is actually because it is just to curry favor, after all, this is the first battle of the sixth plane invading front, so you have to let the most elite go up and make this first kill!

As for the usefulness of sappers, nonsense, of course, they are used to build camps and fortresses, after all, the fish-people don't have decent buildings at all, not to mention, even the mouth of the valley is just hastily tired of two large rows of stones as a protective body, there is a mess of use!

Therefore, for these unqualified buildings, it is natural to directly send undead sappers to tear down and rebuild, otherwise, although there is only one entrance to the valley, but don't forget that there are enough fish people, if they go crazy, the surrounding geographical environment will not be able to hold even if it has been transformed into the underworld, after all, these surrounding peaks are even if they are transformed into smooth stone walls with a 90-degree slope, and they have prevented the other party from digging the wall foot to come in, but it can't stop people from building wooden planks to come in!

Therefore, it is necessary to naturally strengthen the surrounding mountains and establish an extremely solid defense line on the top of the surrounding mountains!

Otherwise, not to mention anything else, if the number of fishmen provoked a ruthless attack, the surrounding peaks could be filled with human ladders, after all, these peaks are not high, to put it bluntly, after all, this is just a small volcano that has been dead for a long time, if there is only one exit, and it is far away from the fish-man gathering place, Wang Fan will not choose here.

After all, if you choose a place that is too close to the fish-people first, then it is likely to be attacked again, after all, the fortifications have not been built at that time, what can you do to resist the crazy fish-people?

Therefore, the first choice is to be far away from the location of the fish-people, and the location is hidden, so that the undead sappers can build the fortifications first, so that even if they are discovered later, they can rely on the fortifications to rely on the undead and fish-people who have teleported from the underworld during this time to fight!

Therefore, Wang Fan chose this place in order to fight a time difference, what he wanted was to be able to win the initial period of time to build fortifications, as for the rest, as long as the number of the undead army is enough, will they be afraid of fishmen?
