After Yuan Chenfei's parallel space theory was finished, he looked at Mystra.

Mystra chuckled, but said nothing, and just vanished, not knowing if his laugh was a mockery or a satisfied laugh.

However, Yuan Chenfei knew that his theory might have limitations, but there would be no major mistakes.

Because this is what he himself realized.

He even saw a little bit of the outline of the four dimensions, and sensed the existence of a little parallel space, which would not have been possible without that.

With another Cloud Realm Blue Core, he should be able to see more clearly.

Yuan Chenfei thought.

As if sensing Yuan Chenfei's thoughts, Han Feiyu said, "By the way, Brother Fei, the pearl wood is insufficient." ”

Pearl wood and obsidian crystal were two important resources in their later construction plans, but according to Qu Wei's plan, they would voluntarily give up after only obtaining part of the mine area, and instead planned to harvest it from the Qingkong Clan.

Although the defense of the Blue Sky Clan Fortress is much stronger than that of the stronghold, there is no problem with stepped defense enhancement there.

So after hearing Han Feiyu's words, Yuan Chenfei smiled and said, "It's time to attack Mountain Rain City." ”

Mountain Rain City is the closest city to the Giants' territory to the Blue Sky Clan, built on a hanging mountain.

Since the Qingkong Clan occupies a strategic and active position in the fairy world, Mountain Rain City exists as a logistical support ground for the fairy fortress, and does not gather heavy troops. However, after the appearance of the giant territory, the Lord of the Blue Sky directly increased his troops by three troops, expanding the number of soldiers here to 70,000, and the total population reached 120,000.

If it weren't for the restrictions of the gods, the Lord of the Blue Sky might have sent more troops.

Even so, it is not easy to build such a city.

The most important thing is that the cyclops can't fly, and for the city of Hanging Mountains, it is difficult for them to function. Although the power of cyclops throwing stones is still good, the lack of system support is far from enough to form a big threat. As for space fighters, don't think about it, the Qingkong clan is good at space, and there are many ways to deal with space fighters.

In this case, if you want to take the city, the main force can still only be Yuan Chenfei, and the method is also the old method - infiltrating and destroying.

On this issue, everyone has actually discussed it for a long time, and has been waiting until now, in fact, it is waiting for Yuan Chenfei to make a breakthrough in space.

Since now that there was only one Cloud Realm Blue Core left to break through, Yuan Chenfei felt that it was time to prepare for action.

"Why don't you grab a cloud realm first, and then go when you officially break through?" Xia Ning said.

Yuan Chenfei shook his head: "To catch a cloud realm, you have to attack the stronghold once, which will cause a change in the entire strategic plan." There's no need, this final breakthrough will be completed on the battlefield. ”

"Then be careful yourself. ”

——————————————————

Mountain Rain City.

This is the city of the Hanging Mountain, which is located closest to the Giant's territory, and you can even see the Giant's city from the top of the peak here.

Qingri stood at the top of Mountain Rain City, and at this moment he was watching with his hands in his hands, and behind him stood a bald girl of the Qingkong Clan.

Suddenly, he said: "The order goes down, the whole city is on alert, and Yuan Chen is flying." ”

The bald girl was a little surprised: "Just him?"

"Yes. Qingri replied, and then he frowned: "But it's already troublesome...... He seemed to understand a little bit of the secrets of space, and I could feel the familiar aura in him. ”

The bald girl's face changed slightly: "So fast!"

She didn't doubt that Yuan Chenfei could understand the secret of space, but she was surprised by Yuan Chenfei's speed.

"Just him?" she asked.

"yes. Qingri nodded.

"That's fine. The girl said.

"It's not too good, since you dare to come, there is always something to rely on. ”

The girl raised her eyebrows, looking a little unconvinced, but she didn't say anything after all, just took a step forward, and the person disappeared in an instant, and when she reappeared, she was in the City Lord's Mansion.

The two Qingkong Clan soldiers saw the girl and said respectfully at the same time: "City Lord!"

The girl said in a rambling voice: "Yuan Chen is here, activate the space monitoring, and keep an eye on him!"

"Yes. ”

The girl glanced meaningfully into the distance.

——————————————————

Walking out of the giant's territory, Yuan Chenfei came to the foot of Mountain Rain City.

Looking up at the fortress suspended in the air, the first level you have to pass is the flight level.

Since the hanging mountain floats in the air, anyone who flies up the mountain can easily be exposed to the surveillance due to the lack of shelter.

But this is not difficult for Yuan Chenfei.

He directly tamed a falcon.

The Sky Falcon is a unique bird of the Blue Sky Clan, with a peculiar appearance, a huge size, and long narrow wings, which look like a fighter plane when flying, and the two wings do not need to be flapped, but are directly parallel to the body, as if gliding - it is typed by the tail jet.

Eagle cannot transform into a falcon, so this creature is also the most difficult to monitor.

After domesticating a falcon, Yuan Chenfei hid himself directly under the wings of the falcon, and it flew to the Hanging Mountain with him.

The monitoring method of the Hanging Mountain is mainly space, and almost any life can be detected when it is close to it, but Yuan Chenfei now has an understanding of space, and easily avoids the spatial induction, in the monitoring of Mountain Rain City, this is a Sky Hunter Falcon, and there are no other life.

Falling on the hanging mountain, Yuan Chenfei put away the Sky Hunting Falcon and walked towards the mountain. Since the Qingkong Clan is mainly space-based, and the defense methods against phantom concealment are relatively average, Yuan Chenfei easily entered Mountain Rain City.

However, it is easy to get in, and it is more difficult to wreak havoc than in Goblin City.

This is not to say how strong the defense power of the Qingkong Clan is, on the contrary, they are not as good as the goblin city in terms of defense due to their lack of technology. But here's the problem - the Blue Sky Clan has almost no core key.

They don't have a defensive shield, and the alchemy level is average, so the energy tower and the alchemy tower are not cores, and even if they are destroyed, the blow will not be big.

The main defense method of the Blue Sky Clan is the city suspended in the sky, isolating most of the opponents who are not good at air combat, and then there are alchemy arrays scattered everywhere, as well as a small number of alchemy turrets. The overall defense is scattered, but it is combined into a whole in the scattered.

This makes it difficult for the strategy of smashing the yellow dragon to the core.

This is also the foundation of the Qingkong Clan's reputation as a strong killer, those strong people's best means of destruction are difficult for them to work, and all kinds of weird spatial methods have the power to turn the tables.

If it weren't for these spatial abilities, even the Qingkong Clan would only be able to master by a very small number of strong people, and they could even stand tall in the forest of strong clans based on this.

Even so, the Blue Sky Clan, whose natural level was only twenty, was also in the middle of the alien race, and it was the object that many powerful races did not want to provoke.

What really restrains them is the goblins, who rely on numbers to win.

Without a core lifeline, Yuan Chenfei simply didn't think about destroying any important facilities - he walked directly towards the Qingkong Clan barracks.

There are four barracks in Mountain Rain City, three of which are outside the city and one inside the city.

What Yuan Chenfei is looking for now is the barracks in the city, which contains about 18,000 soldiers of the Qingkong Clan, and as the only soldier who can be stationed in the city, he is also the most elite soldier of the Qingkong Clan.

If there are no key facilities in the city, then just blow people up.

Changing into the appearance of a Qingkong Clan soldier, Yuan Chenfei walked into the barracks in a big way, and at the same time took out a super bomb and prepared to set it up.

At this moment, Yuan Chenfei's heart suddenly moved slightly.

"Huh?" he sensed, and the space around him seemed to fluctuate strangely.

This is......

Yuan Chenfei's pupils widened suddenly, and the next moment Yuan Chenfei took out not a super bomb, but a teleportation light, and the person had disappeared in an instant.

At the same time as he disappeared, the place where Yuan Chenfei stood changed, and all the matter was annihilated in an instant, as if it had never existed.

Silent, but with the power to destroy everything.

Yuan Chenfei had already appeared on the other side of Mountain Rain City - he didn't pass it out, which meant that the space had been blocked.

Sure enough, although there was no energy shield, the Blue Sky Clan could still block the entire space.

Before he could react, strong spatial fluctuations had struck again.

Yuan Chenfei didn't have time to take the light of teleportation again, so he directly activated the ethereal bracelet.

Space interference.

Not far from Yuan Chenfei's side, a house has been annihilated.

The attack from the Blue Sky Clan, strange, powerful, but extremely silent.

The alarm in Shanyu City could not be alarmed, and the whole city was still quiet, but Yuan Chenfei knew that he had fallen into a net.

Those Qingkong clans have been waiting for him for a long time.

How did they find out?

Yuan Chenfei was horrified in his heart.

He raised his head sharply and looked into the unknown void, and a pair of eyes had fallen towards Yuan Chenfei through the endless void.

Gaze to eye.

Yuan Chenfei's heart trembled: "Skyclave, four-dimensional vision!"
