Rocky and they fought the ground, but Orton was not idle underground, and even what he did was far more complicated than what Rocky and they did.

Thinking about what Orton has done, he first has to figure out the principle of the mobile fortress in the shortest possible time, and then he has to figure out how to get this big guy moving, and when the magic stone arrives, he has to arrange for those workers who don't know anything to charge the mobile fortress, and when all this is done, he has to select a few people to teach them how to drive the mobile fortress.

It can be said that apart from simple manual work, no one can help him at all, and more importantly, he must complete everything in a very short time, otherwise Rocky who fights on the ground will not be able to withstand it.

In this situation, the difficulties faced by Orton can be imagined, he is even more difficult than Rocky, so in the end he had to use some compromise methods, for example, in order to be able to end the battle as soon as possible, he had to shorten the charging time of the fortress, so don't look at the mobile fortress is driving very fast now, but in fact, the energy is not sufficient, according to Orton's calculations, at most it can only be driven outside the ruins, and how to transport this big guy away at that time depends on Rocky and Karina to figure out a way.

As soon as she heard what he said, Karina, who had just relaxed, became nervous again.

Now that they have opened the fortress from underground, not only the fortress is in hand, but also all the design materials related to it, and then as long as the fortress is brought back to Beishan Village, everything is done, so there must be no mistakes at this juncture, otherwise it will really be called a waste of work.

So the two of them immediately had a meeting with Orton, and after some discussion, they finally came up with a solution, which was to use the fleet to hang the fortress from the ground and transport it back to Beishan Village!

The mobile fortress is a veritable behemoth, and it is impossible to rely on floating ships to transport it away, even if it is not possible to use battleships, unless it is transported to Sky City, but the Sky City lands on land, then it is called a big thing, whether it is Mary's Rose City or Lodge's Kartos City, it is impossible to descend casually, so if you think about it, you can only rely on the power of the fleet to transfer the mobile castle away.

With the decision made, everyone immediately went into action, Rocky and Orton continued to sit in command of the fortress, trying to keep the fortress as far away from the ruins as possible, while Karina returned to the fleet and arranged for the fleet to lift the fortress away.

Half an hour passed quickly, and at full speed, the mobile fortress finally opened the ruins of Cassin City during this period, and when they left the ruins, the number of demons chasing them was significantly smaller, but it was only less, and there were still more than a hundred or so demons running wildly with the mobile castle.

This is naturally a good phenomenon, because compared to the countless demons before, a hundred or so demons are nothing in the eyes of everyone.

But again, as the ruins of Cassin City grew farther and farther away, the power source for the mobile castle dried up, and eventually slowly stopped in place.

Fortunately, Karina's fleet was also ready at this time, so as soon as the mobile fortress stopped, dozens of warships slowly descended and threw countless iron cables downward, and at the same time, the air demon warriors tied these iron cables to the various gun ports of the fortress one by one.

Naturally, the demons were not idle in this process, and the hundreds or so of demons that followed them continued to harass, but in the face of this level of harassment, the fortress made of steel was completely indifferent, allowing the demons to attack but not moving at all.

In this way, when all the iron cables were tied to the fortress, dozens of battleships rose into the air together, and the fortress like a hill was pulled up little by little, and soon it was pulled into the air!

Because the fortress is too big and is still made of steel, it is extremely heavy, even if dozens of warships are dragged together, it can only lift it more than ten meters above the ground, and it is impossible to get any higher.

But this was enough, the height of more than ten meters may not be anything for the battleship and the Sky Demon Warriors, but at least it was enough to make the demons on the ground no longer a threat, so then the fleet pulled the fortress all the way forward, all the way to Beishan Village.

When they came from Beishan Village, it took Rocky and them a full three days, and now it also takes the same amount of time to return to the village, but fortunately, they did not encounter any danger in the process, and the flying demon that Rocky and the others were most worried about did not appear, so after three days, everyone returned to the range of Beishan Village.

As soon as he returned to Beishan Village, Sky Wolf City, which was responsible for defending the village, sent troops to greet him, followed by even the city lord Xiao Tian came in person, no way, the things that Rocky brought back this time were too unexpected, Xiao Tian had to come and see it in person.

In fact, for Rocky and Karina's outing, Xiaotian, the city lord of Sky Wolf City, knew about it, and even he knew what the two of them were going to do, but Xiaotian was very good at being a person, and he knew very well that this kind of thing was not something he should ask, let alone him, even the Sky Alliance would not ask, so he just did his duty to defend Beishan Village, but when Xiaotian never expected it, Rocky would bring back such a behemoth back and forth, and in this way, he couldn't help but ask, firstly, to satisfy his curiosity, and secondly, to give an explanation to the alliance。

Rocky and Karina knew this idea of Xiaotian, and neither of them deliberately avoided or concealed it, because it was unnecessary, and besides, the mobile fortress was so huge that it couldn't be hidden at all.

So when Xiaotian got the news and rushed over, instead of hiding it, the two of them warmly invited him to board the mobile fortress.

"Oh my God...... This thing...... How the hell is this thing made?"

When the mobile fortress was placed outside the back mountain village, and Xiaotian came to the land at the invitation of Rocky and others, and came to the front of the fortress, the well-informed city lord of Sky Wolf City couldn't help but open his mouth wide at this moment, he looked up at the fortress blankly, and was stunned for a while before turning to Rocky and Karina: "Both, this is the lost technology you discovered?"

"Yes. ”

Rocky and Karina nodded noncommittally at the same time, and then Xiaotian looked back at the fortress, his eyes becoming more and more solemn.
