The speed of the Yin Water Beast was much faster than mine, and it even generated waves of water before quickly disappearing in front of it.

I immediately began to speed up, shaking the oars as fast as I could, my heart was anxious, the Ghost King Hall should have launched an attack, and the time point was just stuck when the multi-city main formation was about to be completed, one day earlier than expected.

Both sides are racing against each other for time.

If it's just the three brothers of the one-horned ghost king, it's still easy to do, more than half a step now has three lines of defense, and they can carry it for half a day.

I'm afraid that the Ghost King Palace will come out, and now that the magic circle is not perfect, the probability of being able to carry it in more than half a step is very small, and if you don't get it right, it will enter the white heat.

I gritted my teeth and paddled hard, I didn't think it before, but now the situation is suddenly tense, and every minute and second seems incomparably long. I don't know how long it has been, whether it has been two hours or an hour, or less, but the anxiety has made me lose my estimate of time.

"Roar! Roar! Roar! ”

"Buzz Buzz ......"

Finally, through the misty gray fog, I faintly heard the roar of ten thousand beasts, and the characteristic tremor of the crossbow string of the bed, which became clearer and clearer.

A quarter of an hour later, Duocheng jumped out of the water level of Yinshui Lake and was in sight.

When I saw it clearly, I was shocked, the first line of defense had been breached, and the single wall blocking the ice road had been submerged in the tide of monsters, densely packed, stacked like mountain-like monsters almost filled in the city wall, and was slapping the urn city outside the main city in waves.

I immediately took a detour, and in front of me was the ice path and countless monsters, and the Yin Water Beasts were also densely gathered there, waiting for the waves to rise before attacking, there was no way at all.

At this time, looking at the entire battlefield from afar, there was really a feeling of heart-pounding, many monsters were accidentally squeezed into the water, and they would immediately be torn apart by the yin beasts in the water.

After I quickly detoured to the side of the Demon City, there were also some docks there, although the urn city was said to be built outside, but in fact, it was stuck on both sides, and there was no opening, as long as the urn city was not lost, the defense of the main city was only on one side.

Soon, I landed on the shore, but what left me speechless was that although there were no large-scale monsters on the other three sides of the city, they were not at all, and there were still hundreds of them as far as the eye could see, and I don't know where they came from here.

"Roar! Roar! ”

The monster spotted me and rushed at me.

I kicked the dock and used my strength to make the boat retreat, and I reluctantly returned to the water.

These monsters are not strong, but there are a lot of them, and most importantly, they must not be allowed to stain the ice, otherwise the material will fail.

I cautiously circled them, trying to shake them off and go another way, but when the monster found out that I was like a stalker, it didn't let me out of sight at all, and blocked the water's edge to prevent me from approaching.

I'm in a bit of a hurry, I can't go on like this, if they attract flying monsters, things will be even more tricky.

After thinking about it, I immediately took out the horn given to me by Meng Po Ghost last time and blew it, two short clips and one long, which is an unwritten rescue code for Qimen.

Soon, a dark shadow flashed in the direction of the urn city, it was the three-eyed lang.

It swooped down and lifted me into the sky and flew towards the city.

"How?" After storming into the city, it asked.

I nodded hurriedly: "That's it, two hundred." ”

"Okay, everything is ready, only the east wind is owed, and it is waiting for you; If you don't come back, we're going to forcibly activate the circle, and as for that weak gap, we'll have to use people to plug it. The three-eyed lang said, and after speaking, he flew directly to the place where the previous pile was dirty.

When I got to the position, sure enough, all the array mages were waiting there, and the three layers outside and the outer three layers were surrounded by heavily armed armor soldiers, and the white-haired old man I had seen before was also there.

After landing on the ground, I handed the bag to them, and the white-haired old man opened it, his eyes lit up, and he said, "Good, good, the color is very good, with these materials, the two-hour formation can be activated." ”

I was overjoyed, and Sanyanro was also relieved.

Then the group of array mages muttered for a while, and began to uproot the previously tainted array stakes.

They are very careful, and they do not pull it directly, but start well, and then one by one in order, divided into two groups to repeatedly calculate and measure before they dare to do it.

My eyelids jumped and I said, "Can't you just pull this thing out?" ”

"Of course not, you should know something about this material when you go down, it is made of very pure yin qi condensation, once it is inserted into the formation base, it is even a semi-activated state, and the energy contained in it is quite powerful, once it is pulled out wrong, it will explode immediately, not to mention ordinary people, it is difficult for those who enter the Dao to bear it." Three-eyed Lang explained.

My eyelids jumped, I really didn't expect this thing to be so powerful, but when I thought about it, this magic circle was built with more than half a step and all my strength, it must be extraordinary, and the materials used will naturally not be bad.

Moreover, Yin Qi is a kind of nothingness, to condense into such a thick ice, I don't know how many years it will take, freezing three feet is not a day's cold, suddenly exploding, the power must be terrifying.

This thing is probably only produced in the Nine Shades of Cold Prison in the underworld.

Suddenly, a question suddenly popped up in my mind, if this thing is only available in the underworld, then where did these dense and countless array piles come from?

Could it be that he is also from the Nine Hells of Cold?

If that's the case, then the relationship between more than half a step and the underworld is even more intriguing, doesn't it mean that old and dead don't get along? How did you get such an important strategic material in more than half a step? And so many?

When I was in the Nine Hells, I estimated that I had cut two hundred, and there were probably three or four hundred in it, which was far less than the huge number here.

To accumulate so much, it is certainly not something that can be achieved in a short period of time.

Is it not bad to have a good relationship with more than half a step and the underworld a long time ago? Or, simply an alliance? And it's still a long time?

After thinking about it, I tried to beat the side drum and asked Sanyanlang, "Is this material a specialty of the Nine Shades Cold Prison?" ”

The cold prison is extremely cold, and I am afraid that only that kind of environment can freeze all the yin qi.

The three-eyed lang nodded slowly, and said, "It should be, the place where the yin qi can condense, there seems to be no other place except the Nine Shadows Cold Prison." ”

I raised my eyebrows, more than half a step and the underworld must have had a very secret past a long time ago, so long that everyone forgot about it, even the second king of the underworld, Qin Guangwang, didn't know very well.

……

Although the formation mages were cautious, their speed was still not slow, and they first pulled out some good array piles next to them, and then began to pull out the dirty array piles one by one. It's like mending the floor, if you want to replace one of the pieces, you have to remove the next piece, otherwise you can't disassemble it.

There are also some array mages who take out the ice cubes and start processing, depicting dark silver and dark gold inscriptions on the outside, the movement is very fast, and it is very regular, it looks like it is printed uniformly, I was dumbfounded when I saw it.

Three-eyed Lang said: "The Ice Scale Flying Frost Array is my half-step multi-pressure defensive array at the bottom of the box, which can be attacked and defended, the most difficult of which is the acquisition of materials, which is most suitable for battlefield defense and layout, and it can be large or small, very flexible." ”

I nodded, and that was.

Don't say anything else, let's just talk about this array, I was quite puzzled last time, why did the people of the Ghost King of Bishan come in, but they didn't raid the array piles that had been arranged, and pulled out the array piles and destroyed them? Because of such a large range, more than half a step must be guarded on the whole line, and it is naturally weak everywhere.

It turns out that the array pile can't be pulled out randomly, otherwise it will be suicide, so many array piles, as long as the materials are sufficient, they can be completely filled after pulling out, it's useless, but it's better to kill the formation mage to draw some money from the bottom of the kettle.

This is indeed suitable for the chaotic battlefield.

If it is an ordinary magic circle, as long as one of them is moved, the entire magic circle may explode directly at the moment of activation, and there can be no external impact at all, it is too easy to destroy.

"As long as the formation is formed, the one-horned ghost king is helpless to add three heads and six arms, unless the main force of the demon city is dispatched, it is as stable as Mount Tai in half a step." Three-eyed Lang said confidently.

I also believe that such a large magic circle, needless to say, is powerful, if the one-horned ghost king can't even pass Bai Xiangyue's level, it is impossible to compete with the magic circle by relying on the numerical advantage of monsters.

"By the way, what's the situation outside?" I asked hurriedly.

"Not very optimistic." The three-eyed lang shook his head and said, "This time the monsters are even more turbulent, especially the flying monsters, there are very many of them, and their strength is also stronger, although they were finally destroyed, but the outer wall was also lost; Now only the urn city is left, once the urn city is broken, the main city may not be able to carry it for long, there are too many monsters, it can be completely spread out on the whole line, and the defense pressure will be very large. ”

I frowned, which was what I had expected.

At this time, two people came running not far away, it was the fourth and fifth, both with injuries on their bodies, one injured his arm, and the other had a cut in his chest, but the person looked fine, maybe it would affect the combat effectiveness, but there was no big problem.

Seeing this, the three-eyed man turned his head to look at me: "The fourth and fifth were injured when the outer wall was breached, now come and replace us, let's go back to Urn City, there is an urgent need for manpower." ”

I said yes, so the three-eyed man rushed to the sky with me and headed towards the front line of the urn city.
