The battle situation on the west side of the mountain range, old Kavigong was also a little incomprehensible. However, as the commander of the northern battlefield, the west has nothing to do with him.

He just had to pay attention to whether the enemy in that direction was moving back, and that was it. The old man was busy fighting wits with an abyssal lord, and he didn't have time to deal with the empire to the west and what he wanted to do with the floating island that suddenly appeared.

Besides, even if it is reasonable, it is another matter whether people listen to it or not. For Vida's militarism, there are empires on both sides, and there is no question of who is under whom.

And as the inheritance of the ancient magical civilization, the floating island is really tiring to deal with this kind of person.

Although the old Kavi Gong is a great nobleman of the empire, he also knows very well what kind of face this kind of person with ancient inheritance is.

plus what he is facing, but he is the main force of the evil camp. An army dominated by demons, as well as three Abyss Lords, appear from time to time.

It can be said that one wrong step on such a battlefield will bring serious losses. How can you care about other battlefields.

And as the casualties increase, so does the pressure from the enemy. This is not an illusion, the number of enemies is indeed increasing through the calculation of the staff officers' reports on the battlefield, as well as the reconnaissance of airships.

It doesn't matter if it's a demon, or it's an army of another race. The only explanation is that the enemy has reinforcements.

Reinforcements from the underworld are understandable, because somewhere in this battlefield, there must be entrances and exits from the underworld.

Even if they don't, the gray dwarves can dig. Demons can continue to summon their own kind from the abyss into the Maze by sacrificing the dead on the battlefield.

In order to prevent such a situation, it is not only necessary to properly dispose of the remains of the dead after every battle. It is no longer possible to leave only a few proofs and then hastily bury or burn the remainder.

There is a greater need for the Church members of the Light Camp to appear to help purify the souls on the battlefield. Perhaps these souls of the dead with resentment and murderous aura are more favored by demons than flesh and blood.

This also creates a troublesome situation, that is, after the battle, if the result is not for the human side to dominate the aftermath of the battlefield, then it can be regarded as a defeat for the human side.

In short, the enemy has a tendency to fight harder and stronger. In the face of such a battle situation, even if Xilu is willing to hand over the command, the old Kawei Gong has the heart to be unable to manage such a big mess.

In order to cope with the increasing number of enemies, the battlefield on the north flank inevitably shrinks the area of its defense, so that its own forces can be more concentrated.

In this difficult situation, there are still commendable and brilliant achievements. That is, around the surviving magic tower, the human race has won a big victory, whether it is attacking or defending.

It's just that such victories are difficult to replicate in large quantities. Because these magic towers in the north of the Wind Emperor Mountain Range that still remained, they were originally far away from the traffic, so they were not easily pushed away by the previous evil camp coalition forces.

At present, the situation of the war has changed from a rapid march to the south to a regional battle for mutual exchanges.

Only then did some of these originally unimportant magic towers become important nails nailed to strategic points.

It's a pity that there are very few such magic towers. There are only three or two magic towers worth using in the entire battlefield.

While there are still a few surviving magic towers, those places are at best used to house wounded soldiers, or as a staging post for supplies, or as a temporary shelter for troops.

And such an actual battle example made the old Kavi Gong think of the feasibility of a tactic. To this end, he found a magician who was hiding and pretending to be dead, and asked, "Is there a way to build a magic tower quickly?" "Do what?" Lin was stunned by the question, and asked rhetorically. "I'm thinking about the possibility of building all the way to the north and fighting all the way north.

I also don't want a full magic tower, I know how expensive it is to build a three-story tower and how many precious materials it costs.

All I want is the most basic function, which can be used as a watchtower, can cast attack magic, and support nearby troops.

It's okay if it's not a full magic tower. "This means that I plan to insert the tower all the way to the enemy's base camp!

Why such tactics have a strong sense of immediacy. Lin said seriously: "Isn't it really okay to have a complete magic tower?"

Your Excellency, do you know how many people will be frightened by such an approach? "Meaning, you do have a way to do it, right?" Old Kavey Gong also asked hopelessly at first, but now he asked with great interest.

Lin thought for a moment, snapped his fingers, and shrouded the Chinese army's tent with the magic of the night starry sky. Then he unfolded a number of design drawings about the magic tower, and many details in all aspects may not even be understood by a genuine magician, let alone a nobleman.

Although the old Kavi Gong was a great nobleman of the Empire, this status did not allow him to understand someone's design.

Lin showed this, but he just wanted to tell others that he had done research very seriously. "I do have the method to build a full three-story magic tower at an unbelievably low cost," he said.

And as long as the preparation is done well in advance, the construction time can be completed in a few days, but it requires a lot of manpower.

I think this definitely meets your requirements, but have you ever thought about the consequences? Asked by this rhetoric, old Kavi Gong thought about the reason for the magician's warning.

He wasn't a young man who didn't know anything, and he knew immediately that if this set could be used against demons, it would definitely be able to deal with noble lords.

However, after a short period of struggle between the nobles and the magicians, the magicians were both civil and martial, and the magician convention was established and today's situation was formed.

If the magician in front of him can really do the way he imagined the tower, how will the noble lords of the future deal with it?

Will it change the current situation in the Lost Land? How to stop magicians in the future? But in fact, by changing the status quo, a lot of trouble can be avoided.

That is to change the status quo of the Magic Tower being monopolized by the Wizards' Guild. In this way, the pressure of new techniques developed by new tactics will be transferred from the heads of the noble lords to the heads of the magicians.

At this stage, the lords can only have influence over the magic towers built in the city. Although the dominance is still in the hands of the Wizards' Guild, it would be a disaster if the magic tower in the city belonged to a mage who had a grudge against the lord.

Therefore, the lord at least has the right to suggest and veto the tower owners of these magic towers. However, if the dominance of the new form of battle tower can be stripped from the hands of the Wizard Association, it can be said that it will affect the entire Maze Continent.

So the question is, how can we make the magician in front of you willing to release this technique? Old Kavey knew how many people in front of him had not been publicly circulated, but had a far-reaching impact.

It's the part that has been made public, whether it's a forum or a bank, which technology is not a change for the fascination.

In fact, such an idea is a bit too much to take for granted, because of how much thought it takes for a 'concept' to become an applicable technology.

It's not like you can just pat yourself on the head and make things happen. Knowing that a nuclear bomb has been and building a nuclear bomb are two different things, and being able to recite a few words of Amitabha Buddha is a Buddha.

How many things in someone's heart are just known but not why, and because of past actions, people have some unrealistic confidence.

However, in the matter of the magic tower, Lin did not lie. Before, he was busy with the people in the Technology Guild, which was similar work.

In order to build the magic towers on both sides of the Abyss Gate, Lin Ke carefully studied the construction method of rapid construction.

In order to get permission from the human side, before the human side repents, and before the demon side does its best to stop it, the magic tower will be built.

As long as there is permission, the magic tower is built again, and it is useless for anyone to protest at that time. Even if only one tower is completed, the tower on the other side of the Abyssal Gate will not be a problem under the cover of the first tower.

The old Kavig's request for rapid construction was undoubtedly quite an important part of the war. Otherwise, with the construction cycle of the magic tower, it is possible for decades or even hundreds of years.

Then the remaining part is to reduce the function of the magic tower and reduce the expense. After all, if it is in line with the old man's rhapsody, it is not something that can be solved by one tower or two towers.

If you want to build a large number of towers, the construction cost is a hurdle that cannot be bypassed. In fact, Lin began to think about this matter a long time ago, and it also had certain results.

Specifically, it is to change the old way of building a magic tower and using magic materials throughout the body to use ordinary materials as rough embryos and cover magic materials with magic materials to make the magic array work in a similar way as tiles.

The reason why the home of the holy city of Estali has become the Longtan Tiger's Den in the eyes of outsiders is the actual embodiment of this technology.

This approach can be applied to the magic tower, which can greatly reduce the construction cost and maintain the original function of the magic tower.

And because the rough part of the embryo can be molded quickly with cement, the speed of construction will not be slowed down by the inability to directly change the magic material using magic shaping.

If you don't have to build a complete magic tower according to the old man's request, it will be even simpler.

Reducing the defensive function, reducing the internal living space, and building a tower that has no function other than military use will meet such requirements.

However, with so many innovative technologies, it is still difficult to really meet the requirements of building a large number of towers. The difficulty lies in the fact that the strange objects that can be used to create energy pools are not something that can be encountered casually.

An open secret among magicians: the reason why the magic tower is so strong is not to protect against foreign enemies, but to prevent the energy pool from getting out of control.

Although someone already has a way to reduce the cost of building a magic tower. It hasn't actually been built, so there's no guarantee that the new method won't be enough to restrain the pool and reduce the risk of it getting out of control.

And the energy pool is also the key to the magicians being able to keep the magic tower firmly in their hands. There will be no magician who secretly builds energy pools for nobles, there is no corresponding building that binds the energy pool, and loss of control is the only result.

To build a corresponding building, it's the Magic Tower. Since the tower is to be built, how can it be possible to maintain secrecy.

So it's a loop with no solution. In other words, the problem of the energy pool is the last hurdle to complete the old Kavey Gong's idea.

This is also the part where Lin has not yet found a solution.
