"It won't be long before Cloud City will no longer have any protective arrays. ”

This sentence lingered in Lu Xiang's mind for a long time.

If someone else said this, he would laugh and not believe it. After all, the Great Protective Array of Cloud City has existed for thousands of years, and not long ago, it successfully resisted the flint attack of the Goblin Clan.

But the person who said this was Gu Qingtian, the first person in Cloud City, the helmsman of the City Lord's Mansion, and the truth of the meaning in his words could not be denied.

Their Gu family has guarded Cloud City for generations, and they are some of the people who know the city protection array best, and there is no need to deceive him as an outsider.

But what's going on here?

Lu Xiang asked Gu Qingtian with a puzzled look: "Can you tell me what happened, even after thousands of years of corrosion, it is impossible to go from being stable to being broken!"

Isn't the normal formation broken by something, or is it just that it slowly weakens and disappears on its own?

It's so sudden, it's unexpected!

Lu Xiang thought in his heart, if there was something he could do, he would help, after all, once Cloud City was broken, there would be no good but harm for him.

Among the four northern kingdoms, none of them was safer than Cloud City, and if this place was also occupied, where should he go?

Gu Qingtian glanced at Lu Xiang deeply, hesitated for a moment, and decided to tell him about it.

Lu Xiang and the performance of the big corpse were enough to attract his attention, at this time, it was better for Yuncheng to have one more friend like this than one more enemy like this.

"Do you know where the foundation of the Cloud City Formation is?" he asked.

"I don't know. ”

"It's the spiritual vein, under this city, there is a huge spiritual vein hidden, which can continuously produce spiritual energy, the reason why the magic of Cloud City is prosperous, my Gu family is indispensable, but the spiritual vein plays a vital role. Gu Qingtian said, pinching the magic trick, once the white light opened in front of Lu Xiang.

The white light showed a map, which was the map of Cloud City.

Underneath Cloud City, there was a dragon-shaped ore vein, which was the spiritual vein that Gu Qingtian said.

"This spiritual vein provides energy for the city protection array, according to the estimation of the ancestors, the spiritual power in it can last for at least another thousand years, but ...... Just half a month ago, the most core part of the spiritual vein was dug out, and the spiritual vein began to dry up rapidly, and today, the spiritual power in it is less than one. ”

After Gu Qingtian finished speaking, he sighed deeply.

There is such a big problem, and he, the city lord, has a great responsibility.

Lu Xiang listened and asked in surprise: "Why did such an important thing as the core of the spirit vein be dug up casually? And the time is so coincidental, just in time for the arrival of the goblin army." ”

Gu Qingtian and the housekeeper glanced at each other and did not speak.

A few minutes later, the housekeeper said, "Childe doesn't know, in Cloud City, there are five real magicians, the Gu family occupies two seats, and the other three are all from other families. The current Cloud City is no longer the sole owner of the Gu family, the caretaker of the spiritual vein, and there are people from other families, so we suspect that it was the people inside our Cloud City who did it. ”

"And this person must be among the four families of the Gu family, the Song family, the Huang family, and the Li family. Gu Qingtian added.

What do insiders do......

Lu Xiang touched his chin.

What are those individuals doing this for, once Cloud City is destroyed, it will be a devastating disaster for any family, could it be that someone has already negotiated the conditions with the goblins outside?

"What does that have to do with you sucking the girl's blood?" he asked.

"Little brother doesn't know, for what happened today, the ancestors of the Gu family have long expected it, and the ancestors have left us a method, which can use the people who practice magic as the foundation to form a new formation. However, the premise is that the person who forms the eye of the formation must suck a large amount of essence blood. ”

Gu Qingtian said, his face showing some unbearability.

He uses himself as an array eye, and he needs to suck blood, because of his lack of strength, he can only use it by sucking the essence and blood of boys and girls.

Hearing him say this, Lu Xiang's mind moved, and he asked tentatively: "Form a new formation, then those who are the foundation will ......?"

A formation that can protect such a large city as Cloud City requires absolutely huge energy, just a few magic apprentices, plus five magic magicians, can easily form it, this is simply impossible!

If you have to do it, there is only one way, and that is to make a forcible sacrifice.

At the cost of the lives of many magicians and magicians, the formation was initially formed.

Of course, this is not enough, if you want to maintain the formation in the future, you have to invest more energy.

To be able to protect the formation of the entire Cloud City, how many people who know magic have to be sacrificed......

"That's right!" Gu Qingtian nodded, affirming his conjecture: "Those who are the foundation of the formation will die!" At present, there are nearly 10,000 magic apprentices in Cloud City, as long as all of them are sacrificed, they can support the initial establishment of the formation. ”

Gu Qingtian did not hesitate.

Among these nearly 10,000 people, most of them are members of the Gu family and its affiliated families, and after this battle, the Gu family can be said to have suffered the disaster of extermination for the sake of Cloud City!

There are other families that are close to the Gu family, and the same is true, the closer the family is to the City Lord's Mansion, the more members who know magic.

Sacrificing 10,000 people can save Yuncheng, and fight to the death, in the end, the fate of Yuncheng will still be held in the hands of others, this choice question does not seem to be difficult to choose.

"At this time, do you still want to continue to stop me?" Gu Qingtian asked.

Lu Xiang was silent.

If this is in the comics of a certain country, someone wants to sacrifice someone for the sake of righteousness, and the protagonist will definitely come out to stop it, and by the way, promote a wave of humanitarianism.

"If even children have to be sacrificed, there is no need for such a force to exist" and so on.

But all the girls are conscious, and the city lord doesn't want to live alone, the Gu family has guarded Yuncheng since ancient times, and now they have to sacrifice themselves to protect the people of Yuncheng.

Having seen the battle between Ge Qianqiu's elite soldiers and the goblin army, he would not be stupid enough to think that the people of Cloud City would have a chance to win if they fought to the death.

This is not a battle between individuals and individuals, but a game between armies.

The goblin army is well-equipped, and it can be seen from the flint that day, it cannot be ruled out that they have stronger equipment, on the other hand, on the human side, they are still using traditional cold weapons such as bows, arrows, knives and guns.

Even those magic apprentices, most of the techniques they learned were to control the city protection array, and in terms of attack power, it could be seen from Song Da's flying quilt that day that they were not much stronger than ordinary people.

"Boom!"

Just then, the ground began to shake.

Above the sky, a large semicircular light shield appeared.

"Look, city lord. The butler pointed to the very top of the mask.

The mask starts at the top and slowly shatters downward, dissipating into the air as the debris falls.

Great array, break!
