The underground space has been built perfectly, the empty space makes it impossible to see the end at a glance, most of the entire sky under Rost has been hollowed out, and unfortunately there is no new discovery after the discovery of the airship.

"Lord Earl!" Seeing Lei Zhe coming, Colmar hurriedly greeted him, and the space here naturally wouldn't be empty forever.

After the location of the portal is determined, there will be some resting here, and the road will be built to pave the transportation track, and this place will be used as a warehouse in the future, and it is normal to use it to transport people after the portal is completely stabilized, and it is also normal to connect the islands on the other side of the earth with Rost.

One is a high-end residential area, and the other is an industrial and commercial development area, and the two places are located in different worlds, and no matter how they develop, they will not affect each other in terms of environmental factors.

"How long will it take to finish here?"

"It's pretty much there for now, but you can't do anything else until you give the order to build the portal, and what we're doing right now is connecting the layers of space below. Colmar explained the situation to Lei Zhe in detail.

Because of the disappearance of the flying ship, there was a very large space below, and Lei Zhe naturally ordered it to be transformed into a cargo platform in order not to make it empty.

"Yes, well done, let's stop for a while, the problem of city defense has been solved like this?"

"The magic shield has been able to be activated normally, but ......"

"But what?" Because these are handed over to Colmar, Lei Zhe doesn't know very well, after all, there is a mayor in Lei Zhe who thinks that it doesn't matter if Rost's defense is good or not, anyway, in the future, when the demons attack, this side will not live normally.

"In our tests, there are still a lot of problems with the magic shield, and the magic is not evenly walked, which may have something to do with Rost's magic tower, so the number of magic towers needs to be increased......"

"How many more?" Lei Zhe hesitated for a moment and asked, the cost of the magic tower is expensive, it costs at least fifty thousand gold coins to make one, and at present, Rost already has eight magic towers, and there are two magic towers in each direction of the east, west, north and south.

The magic tower has many functions, it can defend or attack, and it can also effectively absorb the magic power and then spread around the magic tower through the ground wave.

The cost of that one is too high, and the maintenance cost is not low, and it is just a waste to build that one that is not used by a high-level magician at all.

When the number of magic towers increases, many magic buildings in the city can be used, magic cannons, magic shields, or magic to maintain the temperature in the city, but the loss of magic is serious after all, and the cost of electricity is relatively low.

"At least eight more are needed. ”

"400,000 gold coins...... Let's do it, I'll have to do these things sooner or later anyway, and collect the materials for the sixteen magic towers. Lei Zhe gritted his teeth and was ruthless, Comos can build a magic shield, but that shield can't be maintained without Comos.

Sooner or later, this kind of urban defense construction will have to be done, and it is also necessary to spend some money to buy security.

"Sixteen...... It may take some time to collect it. ”

"Can you do it in a month?"

"Yes. Colmar nodded, it can naturally be done in a month, after all, the magic tower has already been made, as long as you contact those sellers to spend some money, you can get the materials, but the other party's inventory may not be so much, after all, the materials are all high-grade magic materials.

The core of the magic tower is the magic crystal, which is a natural crystal, which is gradually formed by absorbing magic power, and the magic crystal required by the magic tower is the size of a fist, and the price is about 35,000 gold coins, and it is also a priceless thing.

If it weren't for the magic capacity contained in itself that limited its effect, the price would not be low to this extent, and the magic crystal used in the largest magic tower in the empire at present may not be able to surround four adults, and the price of that thing is no longer incalculable.

It's no problem to trade it for a Lancaster City.

The size of the magic crystal determines the amount of magic contained and the speed of the transformation of the magic power, the magician can strengthen and amplify the magic through the magic crystal, and make up for his own lack of magic through external force to release more powerful magic, so the magic crystal can often be seen on the magic scepter.

However, ordinary people can't afford it at all, and the price of thumb-sized magic crystals has reached about five hundred gold coins, and the good ones can even exceed five thousand gold coins, and the bonus is not necessarily very strong, so few magicians use that kind of staff to strengthen their strength.

No matter how rich a magician is, if it weren't for the mine at home, he wouldn't have considered using a magic scepter to burn money.

............

"I can't hold on anymore!, my lord, there's still no way to get out!"

"There's no way yet!" Lancaster was already about to collapse, and he had a strange premonition from the moment he agreed to Shadow to give up his defense, but he really didn't expect that Shadow actually wanted to sacrifice them all, and the people in Lancaster City kept dying, which was even more terrifying than the plague.

When the soul left the body without their control, all the people felt hopeless, and wanted to leave this terrible city, but the more terrifying thing was that they couldn't get out at all, the whole Lancaster had been sealed, and the only thing they could do was to wait for death in the city.

For the first time, Lancaster felt that he was wrong, so wrong, that he had brought all of Lancaster to death, and that his ambition was gone, and that the only thing he wanted to do was to take everyone out.

It wasn't his conscience, but he was afraid, afraid that it would all be destroyed because of himself.

"Your Excellency...... It didn't take long for the magic shields inside the manor to stop it, and the knights outside wanted to rush in to protect themselves. ”

"It's the other way around! it's the other way around!" Lancaster was furious, and then it was like a deflated ball, he had no way to stop this matter, and the knights of Lancaster had been dissatisfied with him for a long time, coupled with the outbreak of these two things, and the incitement of people with intentions, it was already a very good situation that these knights did not directly rebel.

"Do you think I've done something wrong? Now it's because I believe in the judgment that the judge is like this......"
