The so-called crystal is the spiritual pattern crystal stone of the source beast, which is also the main source of high-level source crystals. The spiritual pattern of spiritual cultivation is followed by the spiritual pattern, and the spiritual pattern of the source beast is followed by the spiritual pattern crystal stone. The spiritual pattern of the source beast is different from that of humans, and the power flow of the spiritual pattern is limited, so even the strongest source beast is just like that. But it is different at the crystal level. The spiritual pattern crystal stone can store their power, and it will be quite terrifying when it is released for a long time.

This is just the source beast under the three crystals. A strange force flow will form between each spiritual crystal stone upwards. This force flow is not used for attack, but for strengthening itself. Therefore, the source beast of the three crystal is the watershed between the crystal-level source beasts. Now the army is the group of source beasts that are about to enter the crystal and are already one crystal. Next, soldiers who use spirit-attached weapons will retreat to the second line, and the rest are the matter between spiritual cultivation.

Of course, the spiritual soldiers of the Xueling Kingdom are not the kind of students who have the talent of awakening the spirit intellect in the academy. Most of them only have one or a few spiritual patterns, but their years of military service have made their bodies stronger than ordinary people. In addition, the spiritual patterns are in their bodies and a complete set of equipment that possesses spirits. Seven or eight three or five such soldiers are put together for a long time to train and cooperate, so their collaboration ability is extraordinary and their combat power cannot be underestimated.

And behind them there are spirits released by spiritual spiritual cultivation. Although they are cultivated, they are also spirits. With their center and coordination, their combat power will be raised to a higher level, and even if they face those crystal source beasts, the only problem is not combat power, but the supply cannot keep up. No one expected this sudden beast tide. The frontier camp was almost everyone fighting for it. Under normal circumstances, the supply that could consume a month was consumed in just a few hours.

Especially after the crystal-level source beasts appeared, the consumption of the source crystal was even greater. Among the Aoxue, only the front-line cities could provide support, but they could not resist the violent beast tide, because now almost all of them were crystal-level source beasts. Therefore, the frontier commander of the Snow Dragon Legion had to adopt a strategy of fighting and retreating, so that they could also gain time so that Aoxue Valley could be prepared.

Although Qin Yu and the other two arrived at the front line, the beast king never showed up in the beast tide. The other source beasts responsible for charging could not recognize the legendary Xue Rui beast. If it were replaced by a more powerful tiger and leopard legendary source beast, it would be fine. The momentum and majesty alone could shock the beasts. However, the Xue Rui beast now has no momentum at all, and even Qin Yu could not resist its strength. Who would treat it as a legendary source beast?

Now a few hours have passed, Aoxue City must have received the news, and the royal city should have received it soon, but the time for various dispatches is not enough. In just a few hours, four-crystal-level source beasts have appeared in the beast tide army. With the exception of Qin Yu, only spiritual cultivation of the complete spirit can compete with this level. However, the two are not proportional in number, so they fight and go at the beginning, but they are almost defeated all the way.

At noon, Qin Yu and the other two retreated to Xueyou City with the army again, and the furious beast tide rushed into the valley. The previous beast tide would last at least half a month before this situation occurred. But now it was only a short morning, how could people react? The most important thing is that the range of this beast tide is so large that it is amazing. In the past, the beast tide entered Aoxue Valley, and Ao Li and several cities on both sides could still resist it with the army in the valley, but now the situation has changed.

Compared with Aoxue Valley, several cities such as Xueyoucheng are indeed towering above a cliff a few hundred meters high, but this is only on the side facing Aoxue Valley. Take Xueyoucheng for example. Facing Donghuchuan to the front and facing Aoxue Valley to the left, it is both condescending and unattainable, but on the right, there is a slope downward and directly connecting to the snow field. Therefore, the source beasts that cannot come up from the other two sides can still reach the city from the side. Even if Xueyoucheng is still at the highest point at the top of the slope, it cannot withstand too many of the other parties.

The situation in the other cities was average. It can be said that the entire Aoxue Canyon was gradually surrounded by the army of source beasts. The cities of Xueyou City were still too busy to take care of themselves, so they could not support the valley. In the face of such a great stream, even the existence of the knight officer was unable to turn the world back and could only stand by and wait for change. As the beast tide continued, the source beast of the three and four crystals passed, and the source beast of the five crystals was the first to be affected.

Xueyoucheng, which is at the top of the U-shaped, has now ushered in the first six-crystal source beast. Its huge body rushes up from the side of the snow slope, and even the avalanche on the snow slope is directly smashed by it. The ice-blue body, four pointed horns, paired with four pointed horns on the head, and one pair grows on the left and right sides of the body, like crescent moons. The four horns all have spiritual patterns on them, and six spiritual crystals are surrounding the body. When they run, the whole Xueyoucheng is shaking.

The two knights took action early, but no matter how sharp the sword in their hands or how powerful the snow spirit was, they could not break the defense of the six crystals of ice cows. All the bursting arrows fell on it and exploded were useless. In the end, they had to choose to get stuck. All the spiritual spiritual practitioners in the city climbed up to the city tower. When the ice cow arrived, they launched an attack together, melting all the snow under its feet, and at the same time burst out a huge deep pit on the ground, causing the huge body to fall into it and temporarily trap it.

If one can do this, two or three will do it? If the beast tide is compared to a dense colony of ants, then you can clearly see four or five rats rushing towards Xueyou City in this colony. This can't hold on at all, so you can only order a retreat. The four or five heads and six crystal source beasts shine with spiritual patterns on their bodies, and the defensive garrison retreated step by step.

After the fall of Xueyou City and Xueyi City, they finally reached the left and right wings of Aoxue City. The terrain here is much higher than that of Xueyou City. Moreover, the city on the left and right wings and Aoxue City are mutually supportive, and the construction of defensive offensives is more comprehensive, and it is divided into inner city and outer city. There are three lines of defense in the outer city area, which tightly surrounds the three cities, and on both sides of these three cities are continuous snow-capped mountains, which are equivalent to the gateway to the royal city.

The previous cities were all lonely cities, with relatively few troops, weak defense offensives, and limited materials stored, so they all fell before the evening. However, it was different when they arrived in front of the three cities. Not to mention anything else, even the source crystal storage was enough for more than a month. With the source crystal constantly replenishing the power of the spirit, spiritual cultivation could be exported without any scruples. More than 40 knights were in charge of seven or eight cities and various camps, and there were only one or two in each place, so they were unable to turn the world back.

But now more than 40 are all gathered in the three cities of Aoxue, which is different. Ten are placed in front of each city, and the active crystals are continuously used as supplies. The powerful combat power of the knight officer is 100% exerted, even if it is more than enough to fight against the six crystal source beasts, the confrontation has been formed. The support of the kingdom has arrived one after another, and Qin Yu has all the people in the dormitory.

"Sister Huo Qin Yu, are you all okay?" Heece came first to look at both of them. Qin Yu now put the Xue Rui Beast in the hat behind him, otherwise the people from the City Lord's Mansion would cause trouble again.

"Why are you all here?" Huo Yuner looked at everyone.

"The school has been closed and the support troops have been organized, and we have followed." Xixi said. This beast tide is different from before, mainly the main attack of the crystal-level source beasts, so of course the spiritual students of Buyino Academy have also come.

"How many people have come?" Qin Yu asked.

"Around fifty or sixty, all from different classes, and some second-grade seniors. Now not only Aoxue City, but also other cities near the extreme northern cold region of Xueling Kingdom have been attacked by beast tides, so other students from the school have also gone to other cities. The school seems to have regarded this beast tide as a training." Britney said.

"Fifty or sixty, it's really reassuring." Qin Yu said. This is his true words. Fifty or sixty spiritual cultivation, and the second-grade senior, the Six Crystal Source Beast is no longer a problem.

"Fortunately, there are large troops stationed in Aoxue City, otherwise the consequences would be unimaginable." Tang Zhu said. If any place was attacked, it would have been destroyed like a tide of beasts. Only here with more than 40 knight officers, hundreds of thousands of troops, and the most solid city defense could resist it.

"It's not optimistic yet. Judging from the hierarchical change speed of the source beast, the Six Crystals are probably not the end. This matter is strange from beginning to end." Sen Xi said in a deep voice. This matter was a bit beyond his expectations. Logically speaking, if it was the beast tide caused by the Xuerui Beast, then the Ice Soul Holy Dragon should attack quickly and rescue his people first.

"Yes, if the beast tide that appeared at the beginning this morning was not the beast tide, but the seven or eight crystal source beast, then, while the Xuelong army was unprepared, Aoxue City would be in ruins now. At that time, whether it wanted to launch the beast tide to vent its anger, it would be easy for it to do anything. Why create a beast tide first? Could it be... it is waiting for something!" Qin Yu narrowed his eyes, and the next moment, the three of them thought at the same time.

"Saintly Dragon Stone!" Huo Yuner and Sen Xi said four words in unison.

"What are you talking about, what Holy Literature Dragon Stone?" Several women looked puzzled.

"It's nothing, I'm afraid this will fall on this little guy. I have to go to Yati's office again, only they know the whole story of this matter."
