Anderson's position was conspicuous because he was in the middle of a crowd of people, standing in front of a huge column.

The cylinder was like an oversized Joyce column, trembling slightly, and the crystal on it shimmered red.

The cylinder is a circular platform with intricate formations carved into the center, and this group of earth mages is at the intersection of each formation.

Rogge did not encounter any more obstacles, the reason is simple, a person with a normal phoenix cannot be their enemy.

Xuanqing landed, and the three of them came to Anderson, and Orfina said loudly: "Uncle Dean, I'm here to help you!" ”

"Orfina? Rogge? Philia? How did you guys get here? Anderson was surprised.

Anderson saw the signal, but didn't know that it was Rogge and them, who were concentrating on controlling the closure of the shield just now, and didn't notice Xuanqing.

"Dean, we'll talk about it later, and the top priority is to hold Holker City." Rog looked at the cylinder, noticing its quivering and flickering red light, and was startled, and asked, "How long will the shield last?" ”

"It won't last long, forty minutes at most, plus ten minutes if you count the magic of all of us."

"Nana, how much time do you need?"

Orfina carefully observed the cylinder, estimated it slightly, and said without looking back: "An hour!" ”

Anderson asked, "The energy of the defensive array is about to run out, Nana, do you really have a way to extend the time of the shield?" ”

"Hmmm! I can! Orfina said confidently.

Orfina circled around the cylinder, and with an idea, she took out several arcane devices that Rogge couldn't understand, and assembled and adjusted them.

Without saying a word, the little assistant Elena trotted a few steps to join her.

The two little girls were busy for a while, and the others couldn't intervene, and they couldn't help if they wanted to.

Anderson chose to believe Orfina and said to Rogge and Philia: "The Flying Monster Horde raided Holke City two days ago, and the warning time was too short, and there were heavy casualties. I rushed here to activate the defense array as soon as possible, and I was taken care of by the Warcraft group. The air force of Holke City was killed in order to protect the large formation. ”

The Holker City Air Force is a strong Pegasus Knights unit, and many of Rogge's seniors are outstanding graduates of Holke Academy.

Rogge looked at the corpse around the platform covered in a white cloth, which was stained with blood, and the worst pieces were all stained red with blood.

Rogge noticed that some of the human figures under the white cloth were very incomplete, presumably mutilated corpses.

Thinking of the heroic appearance of the female knights, Rogge felt a heartache and couldn't bear to look at it anymore.

"Can I ask for help from the surrounding cities?" Rogge asked.

"Before the shield was activated, several messenger teams broke out under the desperate cover of the air force, and the news of the attack on Holke City should have been spread. In the past two days, a small force of air forces has indeed come to support, and it is estimated that it is from the surrounding towns, but seeing that there are so many demonic beasts, they all temporarily retreated. ”

There is nothing wrong with the choice of reinforcements, a direct attack is to hit a stone with an egg, and it must be gathered together to form an army-level air force before it can fight against the Warcraft horde.

"The Viper Knights will arrive the morning after tomorrow, with Duke Matilda himself leading the way. I estimate that the support of the front-line troops is also coming soon. ”

Two days is enough for the Northwest Front to organize reinforcements, but I don't know if there are enough troops to support.

"Well, that's what I thought, too, but only if we can hold out until the support arrives."

As soon as Anderson's words fell, the protective shield suddenly fluctuated violently, and a loophole appeared at the top, and the piled up corpses of demonic beasts fell one after another.

Rogge looked up and saw a dark blue dragon shadow quickly rushing towards the loophole, it was Canxing.

Because the air force of Holke City was completely wiped out, Canxing was alone and fighting against a large group of demonic beasts, and his momentum did not fall behind.

"Yoo!" Canxing let out a high-pitched and majestic dragon roar, and the power of the star dragon was in full swing, and even the crowd below felt as if their hearts were tightly grasped by death!

The feeling of the demonic beast was several times stronger, and the weak monster-level and blood-mutated demonic beasts suddenly stopped their movements under the shock of Long Wei, as if they had forgotten how to flap their wings.

Just because the movements stop doesn't mean that the body will stop too, they fall from the sky, very similar to the rain of corpses just now.

Under Canxing's control, Long Wei's influence on humans weakened, and the warriors woke up, wiped the sweat from their foreheads, and made up for the final stab on the demonic beast that fell to the ground.

"Your Star Shine Dragon Spirit King level?" Anderson asked in surprise.

"Well, a breakthrough on the way to Odens City."

This is the best news Anderson has heard in the past two days, and the old dean showed a brief smile, and then he was serious, and said, "You saw that wooden dragon, right?" It's not easy......"

"Wither!"

The strange roar of the wooden dragon once again confirmed Anderson's words, and a circle of green energy fluctuations visible to the naked eye spread out around the center of the poisonous spotted wooden dragon, sweeping through the entire group of demonic beasts.

With the help of energy fluctuations, the demonic beast instantly broke free from the suppression of Long Wei, but became more ferocious and faster.

"This energy wave should be a special skill of the Poison Spotted Wood Dragon, and it may be a natural magic." Rogge thought quickly.

But nature magic is very mysterious, very little is recorded in books, and Rog doesn't know what it is.

The hole finally began to close, and Anderson's body trembled, as if every muscle in his body was straining, and the other earth mages were in a similar state to him.

Having solved the incoming demonic beast without danger, and the loophole was filled again, Anderson breathed a sigh of relief, wiped his sweat, and glanced at Rogge.

Rogge had a question mark on his head.

Anderson pointed with his chin to the two little girls who were busy.

Rogge understood, this is for him to ask about the progress, and by the way, to find out if he can really maintain the shield.

Anderson, who has always been unable to change his color, is really helpless now, once the protective shield disappears, the whole city will face a bloody massacre, he is in a hurry.

Rog walked softly over to Orfina and watched as she assembled the device with Elena's help.

The device has a rectangular casing, which is open at the top and all sides, and the structure inside is too complex for Rogge to read.

But it's complicated, it's very neatly arranged, and it should be carefully arranged by the two little girls.

Orfina sat cross-legged in front of the device like an old man, assembling it like a building block, pausing to frown and think about it, and then disassembling the parts she had just assembled and rearranging them.

Elena sat on a cute duck, leaning forward and staring closely at the inside of the device, clutching a bunch of small parts in her hand, handing them to Orfina.

The two of them cooperated very well, and Orfina didn't have to turn her head or communicate with each other, and her little hand spread out to Elena, and Elena was able to hand her the right parts.

Rogge looked at the two little girls who were concentrating on their work, and they didn't dare to come out, for fear of disturbing them.

The young man held back for a long time, and he couldn't stand the urging of Anderson's eyes, and said in a weak voice: "Nana? ”

Hearing Rogge's "weak" voice, Orfina quickly turned her head, saw that Rogge was intact, breathed a sigh of relief as if she was relieved, and then pouted: "What are you doing?" It's so empty, people still think you're hurt! ”

Rogge's heart warmed, at such an important moment, Orfina thought of him first, and couldn't help but smile.

"Tell me, I'm busy." Orfina urged.

"Nana, how's it going?"

"In the beginning, I need to take out all the devices I use to grow vegetables, and then modify the energy circuit, adjust the input and output, and have to connect them together, and modify the ......."

Orfina said a bunch of things while operating, and Rogge understood it with his ears, but not with his brain.

But Rogge felt that Orfina had a point, because there was a sparkle of confidence in her eyes, and Rogge understood that it meant that the girl had a plan in her heart and a score.

"Oh, I told you that you don't understand, don't bother me, go aside~"

"Oh." Rogge obediently stepped away.

Anderson straightened his ears and listened to the conversation between the siblings, arcane knowledge was his blind spot, so he was no better than Rogge.

Anderson automatically ignored technical terms such as "energy circuit" and asked what he cared about the most, "Rogge, what did Nana say about growing vegetables?" ”

"Oh, Nana grows vegetables in her ring." Rogge explained.

Anderson: "??? ”

Anderson looked shocked and shook his head, thinking he had misheard, "What...... What? ”

"Nana grows vegetables in her ring." Rogge repeated.

After fifteen seconds of silence, Anderson finally accepted the message and asked, "How did she do it?" ”

"Nana's Spirit Ring is very special, it is a treasure of the middle level of the phoenix level, and it can store living plants. So Nana in order to eat...... Well, for the sake of research, self-taught arcane, and after months of unremitting efforts, I was finally able to get the plant to grow in the ring. ”

After nearly half a minute of silence, Anderson let out a breath and exclaimed, "Nana is such a genius." ”

"Haha, of course!" The girl's laughter came from not far away, and Orfina listened carefully to the words that praised her.

Compared to growing vegetables in the ring, it doesn't seem like a difficult task to provide energy to the shield. Anderson was relieved and took full control of the defensive array.

The energy conversion device that Orfina is working on is not complicated for her, and it is much simpler than the device in the Spirit Sky Ring.

The device in the Void Ring converts Orfina's magic into the energy needed to simulate the operation of an arcane device in a natural environment.

The latter is so complex that Orfina racked her brains to invent it, while the former is a ready-made product that has been widely used.

First of all, the finished device is named Device A.

After Ofina's inspection, the core device of the defensive array, the large cylinder, converts energy on the same principle as Device A.

Then it's simple, first change the way to provide energy to Device A to the Warcraft Core, and then dock Device A with the core of the defense array, and the task is complete.

The method of releasing the energy in the magic core is also ready-made, and the small device on the magic core bomb can do it.

However, Orfina needs to be modified, not to let the magic core release so much energy at one time and explode, to control the speed of energy release.

Orfina hadn't made it this far, and she was concentrating on changing the energy circuit.

Rogge thought carefully about what Orfina said, and still didn't understand the details, but he figured out the general steps.

Rogge was sure that Orfina would be able to ...... in an hour It's now fifty minutes before the device is adjusted to provide sufficient energy for the maintenance of the shield.

Now the question is, how to fight for the remaining ten minutes of the shield for a maximum of forty minutes?
