Although this expedition to the North Pole was only a few days, the harvest made Xilingchen very satisfied.

Of course, Su Miao'er didn't find the herbs she needed, but she found other ice-based medicinal materials, and in addition to herbs and the like, there were also a large number of ice-based ores, and Xiling Chen had several large spatial rings here.

As long as the ore is found, it is directly blown up and the raw ore is removed.

Leaving the North Pole, Xiling Chen led the team to the side of the ore vein to check it, and only after making sure that there was nothing wrong did he return to the base of the Purple Moon Guild.

In the past few days, nothing has happened in the Black Dragon Plain, and it is still very calm.

However, this kind of calm is only on the surface, and there may be a conflict when it will break out, after all, many top forces on the mainland have sent people over.

This side of the base.

As soon as she returned, Su Miao'er began to practice in retreat, and Xiling Chen also continued to guide the construction of the Sky City.

He renovated his villa, and it is estimated that in a few days of construction, the villa can test its flight ability, as long as there are no accidents, it is not difficult to fly, as long as his villa can fly, then there is no problem with the city in the sky.

There are a total of four magic towers in Sky City, and the defense and attack are all operated by these four magic towers, which are fully automatic, and only one magician is needed to control them.

The more advanced the technology, the simpler it becomes.

What Xiling Chen has been building recently is a hybrid energy storage array, which is an energy storage device that supplies and stores energy for the Sky City, which is built with magic crystals, magic beast crystal nuclei, and magic gems, which is quite complex.

This thing can only be built by Xiling Chen himself, because he has the power of the Chaos Crystal, even if the technology of this kind of thing is learned by the forces, there is no way to create it.

Of course, Sky City also needs attack capabilities, after all, this thing is designed to fight against the powerhouses of the Sanctuary Realm.

In addition to the four magic towers, Xiling Chen installed some of the cannons that had been removed from the elven warship, of course, these cannons were all transformed by his own hands.

After the artillery is installed, he will also set up a large mage battle platform to amplify the power of magic, relying on the four magic towers of Sky City to attack, even if the Purple Moon Guild does not have a Sanctuary powerhouse, it can compete with the Sanctuary with a few legendary powerhouses.

Just when Xilingchen was engaged in construction, the major forces that came to the Black Dragon Plain made a move.

These teams all started to move in one direction, the dwarves, the two-faced monarchs, the two human empires, and Xiling Chen's side are also observing the situation, and according to the current intelligence, the ultimate goal of these teams is an undead mountain range.

Conference room.

Xilingchen pointed to the map and asked, "What's here?" ”

"I don't know."

All the management shook their heads, this was just an ordinary undead mountain range, although there were a large number of undead creatures in it, but these creatures never left the mountain range.

"I'll send some more men over and take a look." Jing'er said.

"Hmm." Xi Lingchen nodded.

Although the Purple Moon Guild is not very interested in the secrets of the Black Dragon Plain, it is also important to understand what is happening here.

After the main thing was said, the next thing was some simple things, and D-5226, the android girl who was in charge of building the Xilingchen Villa, asked, "President, when will your Flying Villa be tested?" ”

Although she is very anxious about the situation in her hometown, she has no way to leave the universe at present, so she can only stay here in the guild to help Xilingchen get some black technology out.

Although she is an artificial being, she is no different from a truly intelligent being, able to think and communicate.

"In two days, I'm working on a new type of levitation formation to see if I can make it." Xilingchen said.

His villa is a testing ground for all kinds of advanced technologies.

The meeting every few days ended like this, and after that, everyone went their own way, Su Miao'er used the various energy crystals and herbs brought back in the North Pole in the past few days to improve by one level, and now her level is ninety-six.

Time flies, and in the blink of an eye, it is three days later.

The teams of the major forces are currently all stationed in the vicinity of the Undead Mountain Range, and these forces have not clashed in any way, as if they are preventing the undead from rushing out of the Undead Mountain Range.

And on the side of the Purple Moon Guild, the first test of the Flying Villa began.

As Xiling Chen activated all the formations and energy nodes, the villa built with magic technology slowly left the ground.

A translucent oval shield protects the villa so that you don't have to worry about high winds after flying.

The area of the villa is not very large, only thirty square meters, but this test represents whether the Sky City can really fly, as long as there are no problems in the process, the Sky City will definitely be able to fly.

Almost everyone involved in this project is there, some on the ground and some in the villa.

Villa control room.

Several maids are carefully following the process, these are the things that Xiling Chen taught them in advance, and various data are displayed on the screen, energy intensity, shield strength, stability of the villa, energy of the formation, and so on.

"It's flying!" Su Miao'er was suspended in mid-air and looked at it in surprise.

Although she knew what Xilingchen was doing, she was still a little shocked to see this kind of scene in person.

In this magical and vindictive continent, in addition to the legendary powerhouses, there are only some flying knights who can fly in the air, but now other things have appeared.

"Open the Invisible Formation." Xi Lingchen said as he stood behind the maids.

Although it was only a test, it couldn't be seen by others, so after the villa rose to more than thirty meters, Xilingchen reminded.

After hearing this, the maids immediately opened the stealth formation according to the master's request.

"So many days of hard work have not been in vain!" Hayley Delway also said with some excitement, although the former elves have built space warships, but these have nothing to do with her, she is just a legion commander and a user, but this time she participated in the construction, and she is full of a sense of achievement.

Although most of the technology is magic technology, it is also very advanced.

After the stealth formation was opened, the villa began to rise rapidly, and after flying to a distance of more than three thousand meters, the other tests began.

Xilingchen just watched from the control room, because everything was arranged, so he only had to wait for the result.

After more than an hour of testing, I am generally satisfied, although there are still many problems that need to be improved, but these are small problems, some are material, and some are not corresponding industrial systems, and there is no way to be more perfect.

After that, the villa will remain suspended above the base, and as for how to get up, it is through a teleportation formation.
