The remaining more than 900 units of the bison herd, after the bison leader fell, after losing the command, they fought separately like ordinary wild monsters, and no longer had any intention of gathering to fight, even the Sun Shooters who had been launching long-range attacks from a hundred meters away only knew to attack the dragon spearmen around them as if they didn't see it.

More than twenty minutes later, the last two fifth-order bison fell under the sword of Rebecca and Xu Yun.

【Ding! , you win a brilliant victory, you get 810,000 experience]

As the system prompt sounded, the battle finally came to an end.

"Whew!" It was the first time that he had been fighting for so long in a row, Xu Yun gasped and withdrew from the state of dependence, but he didn't dare to rest at all, and immediately ran towards the three shiny bison sheds, and now he had to cherish every second of time.

Xu Yun also tried just now, he would use the mountain fortress without destroying the bison herd, but a layer of invisible light curtain was separated in front of the three bison sheds, and Xu Yun couldn't get close to it even if he tried his best, so he would turn around and solve this bison, otherwise time was so urgent, how could he spend time on solving these bison.

This time, Xu Yun stepped into the ten-meter-high bison shed without any hindrance, and after entering, his eyes immediately looked at the bison statue floating in the air, exuding an earthy yellow light, and without hesitation, he stretched out his hand and held the fist-sized holy icon.

[Name: Bison icon.]

Rank: Fifth Order

Attributes: It can be converted into the architectural drawings of the bison shed, or it can be directly put into the bison shed, when the number of icons in the bison shed exceeds three, you can directly recruit fifth-order brute bulls]

Really!!

Before, Xu Yun was wondering if the holy statues in these three bison sheds could be obtained.

I didn't expect to get it, this was a surprise that he didn't expect, because the entire Raging Tide Island didn't even see a fifth-order recruitment building, which was enough to prove the difficulty of obtaining the fifth-order troops, and the fourth-order barracks of his Tianyun Collar still cost a thousand evolution crystals for He Qixin to get it, and now he has three fifth-order recruitment building drawings for the fortress camp, or the construction drawings of the top pillar of the fortress camp, and he knows with his feet that these three drawings can definitely be worthy of the four words priceless.

Hey?

When Xu Yun took the bison icon in his hand, the bison shed suddenly disappeared, as if it had never appeared, and Joan of Arc and Angel next to him also held a bison icon and looked at him, and the bison shed they entered also disappeared at the same time.

"Alpine Fortress!", Xu Yun immediately looked ahead worriedly, he was really afraid that the Alpine Fortress would also disappear along with the bison shed.

Fortunately, the alpine fortress still stood in front of Xu Yun and did not disappear with the three bison sheds.

After taking two quick steps, Xu Yun put his right hand on the tall wooden door of this miracle building.

Name: Alpine Fortress (5th Order)

Rank: Miracle Building

Effect: Let the class evolve into the form, not the ultimate form, the first order of the class is free, the other ranks need to pay one-third of the recruitment fee, the existence time and the ability to evolve the class rank is related to the guard, the evolution of the unit needs a short time, the time and the number of troops are related to the number, and the evolution of the unit needs to be within 500 meters.

The introduction is very simple, and it is basically attached to what Xu Yueyue said, but there is also a time limit for the evolution of the troops, and this restriction is also the meaning it should be, otherwise if the troops can really be evolved in an instant, Xu Yun really can't imagine how terrible the scene of those giant power alliances that let millions of troops under his command evolve at one time.

Underneath the system panel of the Alpine fortress, there is a small window.

Evolved Class: ?

How much does it cost?

Yes/No

Xu Yun clicked on the question mark behind the evolved troops, and a large number of troops appeared on it for him to choose from, and the troops above were all the God-given troops under his command, and they were within 500 meters, and the seventh-order angel was also on it, but the avatar was gray, and it seemed that it was not selectable.

After weighing it, Xu Yun first moved the 9275 unit of the fourth-order Aurora Warlock to the window of the evolved troops, and then the cost below was there, and naturally there was this evolution force, which required 61.83 million territory gold coins.

Gritting his teeth, Xu Yun pointed his finger that after the resources of the entire Raging Tide Island were cleared, there were more than hundreds of millions of territory gold coins, a large part of which was obtained by Xu Yueyue through the sale of evolution crystals, and was ready to be used to develop Raging Tide Island, otherwise the territory gold coins might not be enough to evolve the troops, which would be a real tragedy.

After clicking confirm, a large number of pillars of light fell from the sky, one by one shrouded the Aurora Vulture, which was originally hovering in the air, as if drunk, they landed on the ground one after another, and then crawled on the ground without moving.

Seeing this situation, Xu Yun was anxious, wishing that these aurora vultures would evolve successfully in an instant, but at this time, he suddenly remembered something, and immediately turned back to An Jie'er and said, "An Jie'er, you hurry up and go back to the city and lead the dragon spearmen back!" ”。

Now the number of dragon spearmen here is only about 7,000 units, after all, they have to fight against a herd of 1,000 units whose attributes are comparable to those of the seventh-order troops, although the other party is like an ordinary wild monster after losing the command of the leader, but it also makes them pay a heavy price, and most of the 50,000 units of the Wild Lan Legion are killed in battle.

"Yes, sir!" , Anjieer began to run in the direction of the base camp, and now the Flying Dragon Emperor was handed over to Xu Yueyue to use, so she could only run back with her legs, fortunately, this place is not too far from the city, otherwise it would really be over, and Joan of Arc and Xiaobai wanted to lead these remaining troops, so Xu Yun did not let the two heroes follow back to transport troops.

After An Jie'er left, Xu Yun looked at the mountain fortress in front of him worriedly, for fear that it would be just the time to disappear, but fortunately, it was not until ten minutes later that the pillar of light on the body of the fourth-order aurora vulture that shrouded nearly 10,000 units disappeared, and the mountain fortress was still there, and it did not disappear because of the time.

The Aurora Fighting Vulture crawling on the ground spread their wings and stood up, and since the Aurora Fighting Vulture would not change its appearance even if it evolved to its ultimate form, the changes in these Aurora Fighting Vultures could not be seen from their appearance.

Holding back the idea of wanting to click on the Aurora Warlock attribute to take a look, Xu Yun first put the 20,000 Sun Shooters into the evolution box, looked at the price of the 40 million territory gold coins, and clicked the confirmation with a heartache.

When the 20,000 units of the Sun Archer also landed on the pillar of light, Xu Yuncai opened the list of evolved Aurora Vulture attributes, of course, it was the Aurora Vulture under the command of Xiao Bai.

Name: Aurora Vulture/Small Creature

Tier: 4th Tier/Perfect

Attack: 212-424

Defense: 182

Speed: 15

Morale: 0

Lucky: 0

Hunger: 64

Maintenance Cost: 300 Territory Gold/week

Life: 910

Trait: Actinic (The body turns into a light element, doubles the attack and movement within 5 seconds, and doubles the damage taken when receiving magic attacks, times/day)

Compared with before, the evolved Aurora Vulture has increased its attributes by about one-third, and it also has one more actinic characteristic, and its combat effectiveness can be said to have doubled, even if it encounters a fifth-order flying class, it will not be unable to break the opponent's defense, of course, one-on-one still has to be beaten by the opponent.

After looking at the attributes of the Aurora Vulture, Xu Yun turned his head and paid attention to the Sun Shooter again, and found that this time it only took about ten minutes for the Sun Shooter to evolve, and a large number of dragon spearmen in the distance also appeared.

"It's fine!" , Glancing at the mountain fortress that had not disappeared, Xu Yun breathed a sigh of relief in his heart, for fear that the large army of dragon spearmen would not have time to arrive.

After the large army of dragon spearmen entered the range of five hundred meters, Xu Yun immediately put these dragon spearmen with a total of 110,000 units into the evolution box, and since the first-order troops evolved for free, they didn't have to worry about the cost of evolution.

Countless pillars of light fell from the sky, almost competing with the scorching sun in the sky.
