When the battle of Silent Fortress began, Xiao Yu and Hilaria joined the troops sent by the Holy Flame Fortress, one of the six major fortresses, and Xun Ya spent a lot of effort, but only persuaded the commander of the Holy Flame Fortress to send troops.

The Holy Flame Fortress is a fortress dominated by orcs, and the orcs are warlike and don't like to hide in the fortress, so they mobilized 400,000 elites to help the Dawning Fortress raid.

Hillaria and Xiao Yu's 300,000 Dawn Army is deployed behind a low mountain, the 300,000 army is mainly composed of bear people, tiger people and sheep people, a total of six arrays, tiger warriors all use five-meter-long spears and axes as weapons, erected weapons from above, it is simply a sharp steel jungle, can easily tear apart all the enemies in front of it.

The combination of this elite army is also scientific, four tiger warriors and a sheep-headed mage are a team, riding a flame giant rhino together, the mage of the sheep-headed human race is good at silence, healing and other auxiliary spells, each squadron is equipped with a giant elephant, more than a dozen elf sacrifices are seated, responsible for blessing the state of the entire squadron, can advance and retreat, attack and defense in one. In addition to the sheep-headed and tiger-headed people, the warriors of the bear people accounted for 100,000, all of them in heavy armor, and held a thick giant shield that was four meters high, and the 100,000 giant shields formed an iron wall that could make the enemy despair.

This army is the ace army of the Dawning Fortress!

Hilaria suddenly moved, immediately sensed it, and said to Xiao Yu with a happy face: "The people from the Holy Flame Fortress are here!" ”

Xiao Yu sat on Dusk's broad back, raised his head and looked in the direction where the voice came from, a black line appeared on the dim horizon, and he could feel the fierce momentum of the other party dozens of kilometers away, this is an elite force that is not lost to this army.

"Put a signal."

Xiao Yu ordered.

An elven mage waved his staff and pointed at the sky, and the green light shot into the air, suddenly exploding into a green leaf pattern. Seeing the signal, the Flame Fortress Army, which was coming in this direction, immediately increased its speed, and it didn't take long for it to join the Dawning Fortress.

When everyone saw the Holy Flame Fortress army, they all gasped.

An army of 400,000 people, equipped with a full 100,000 earth dragons, each earth dragon has four orc warriors sitting on its back, one of them is holding a spear and a strong breath is the orc earth dragon knight, and the other three orcs are holding swords in their right hand and axes in their left hand, and there are five flying axes hanging on their backs, which are the elite warriors of the orc race.

The original Fireblade Tribe, the entire tribe of tens of thousands of people, only Rorome, who was the chief, passed the Earth Dragon Trial and became a powerful Earth Dragon Knight, an army composed of orcs and Earth Dragon Knights, its power can be imagined, and the Dawning Fortress is only comparable to the Dragon Eagle Knights. The orc clan has very strong combat effectiveness, and with the impact of the earth dragon, they are not afraid to block the enemy several times. It's no wonder that the Holy Flame Fortress is rarely attacked, and the Demon Calamity Army knows that orcs are not easy to mess with.

On the battlefield, second- and third-order strength warriors are the mainstream. This Earth Dragon Knights is a hundred thousand fourth-order high-level orcs, and it is composed of the best high-level orcs, such a big hand, only the king tribe of the orc clan can do it.

The leader of the Earth Dragon Knights is a braided, very rugged and wild orc, carrying a crimson giant sword on his back, wearing a guardian gold crown on his head, and a tattered boss skin tied on his back, he is undoubtedly the commander of the Holy Flame Fortress. Its mount, the Earth Dragon, is a mutated golden-backed Earth Dragon with the strength of the late Fifth Order.

"You're the Boss of Hilaria at Fortress Aurora." The orcs rode the earth dragon to Hillaria, "On the way, I encountered some small demon plague army that was not long-sighted, and it took some time to destroy them. ”

Hilaria nodded, "It's good to come." She glanced at Xiao Yu, "What to do next?" ”

Xiao Yu felt that the orcs were very familiar, and the orcs also looked at Xiao Yu more, which surprised the two of them at the same time.

This orc is none other than the remnant of the original sight on Taoyuan Island.

Remnant Yan is the grandson of King Tianyan among the four orc kings, who is war-hungry and a strong man on the famous side. Remnant Yan is also the most favored descendant of King Tianyan. At the beginning on Taoyuan Island, Remnant Yan's strength was not under Bloody Fang, and if the two really wanted to fight, Bloody Fang would definitely not be an opponent on the land of Remnant Yan. That adventure allowed Yan to gain a lot of treasures, and he made great progress in the half a year after he went back, ending the stalemate situation of staying in the late fifth order for decades, and completely breaking through to the peak of the fifth order

When Remnant Yan entered the peak of the fifth order, there was already a faint trace of Wang Wei, which undoubtedly showed that Remnant Yan had the potential to become a king. Orcs follow the law of the jungle of survival of the fittest and the law of the jungle, unlike elves who put all their efforts into one offspring and cultivate it. Remnant Yan's outstanding performance attracted the attention of King Tianyan, so he rushed to the Holy Flame Fortress to serve as a commander and hone his temper well. King Tianyan is an old king, but among the hundreds of descendants, none of them can inherit the mantle, only Yan Yan has a glimmer of hope.

Remnant Yan said with a strange expression: "What's the matter with you?" Remnant Yan noticed Xiao Yu's silver crown and cloak, "Unexpectedly, you became the deputy commander of the Dawning Fortress?" At the beginning on the island, you were able to play our tricks, and although the labor and management did not like you, your courage was more admired. This operation must be your masterpiece. ”

Hilalia was surprised: "You know each other? ”

A fragment of a super engram crystal of the sub-god clan seemed to be on the remnant Yan's body...... There is a small part of the complete crystal, so that a lot of information is incomplete, there are many techniques that cannot be learned, and there is a chance to get the crystal fragments back from the remnants of Yan, so as to restore the most perfect biosynthesis technology.

It's just not the time.

"You're too slow." Xiao Yu said lukewarmly: "Let the soldiers rest and prepare for battle, the task is very simple, the demon camp has been arranged, and there will be a riot soon, we will take the opportunity to launch an attack and penetrate directly into the camp, the goal is to destroy some important buildings and resources in the demon base camp." ”

Hilaria said, "I'm afraid the Silent Fortress is about to start, so we must start planning as soon as possible." ”

Xiao Yu and Hilaria had already arrived, but they just parked the army in a relatively safe area, and for more than a day, Hillaria followed Xiao Yu, sneaking into the demon disaster base camp and assassinating or plundering some demons, not knowing what the purpose was.

Xiao Yu took out a ring and handed it to Remnant Yan: "I brought more than a thousand Great Purification Scrolls and distributed them to various generals and battalion commanders, and purified the soldiers every once in a while to avoid the body absorbing too much demonic energy and being demonized." Let's go, let's go in! ”

The 700,000-strong army marched towards the core area of the disaster area, and the demonic energy became more and more intense, and after invading the body, it would initially cause a feeling of dizziness and weakness in the limbs due to inappropriateness, and soon people felt a burning sensation from the inside out, dry mouth, bloodshot eyes, and made the mood become manic. After such a situation occurs, if it is not purified in time, the demonic energy will gradually erode into the spirit, and the final fate of the organism is demonization.

Demonic energy is a kind of negative energy, and under a large amount of infusion, although it can improve its strength, it needs to be at the cost of overdrawing one's life and losing one's mind.

Remnant Yan led the warriors through the desolate and dry grass, the demonic energy came out of the ground like wisps of smoke, and condensed in the air like mist, and the field of vision was pitch black, he couldn't help but shout: "Lao Tzu hates such an environment!" ”

Hilaria wondered, "You've dealt with the Scourge before?" ”

Remnant Yan snorted: "Some time ago, I needed to retreat, so I went to the south for a while, where the demon disaster is very bad, especially the lava demon clan, there are too many of them." However, they had no intention of invading the mainland, but drilled into the endless fire domain in the extreme south, and the ghost knows what to do without seeing people. ”

"What do you say? Endless Fire Domain! Xiao Yu felt nervous: "All the lava demons ran into the Endless Fire Domain?" ”

"They are going in the direction of the Fire Domain, and there is a small number of demons. By the way, I heard that the demon race is a new race that branches out of your human race, is there such a thing? ”

Xiao Yu didn't bother to answer Yan Yan, and secretly kept an eye in his heart.

I have to pay attention.

Because of the relationship between Xiao Yu's butterfly, the current world pattern is completely different from the original. The demons and the lava demons kept drilling into the endless fire domain, and it was for the "Book of Fire", others didn't know the whereabouts of this book, and it was very likely that Pronos knew. They were the first to get the book, but it was a bad thing.

Hilaria patted Xiao Yu: "Hey, what do you want?" Distraction at such an important juncture! ”

"It's okay, give the order for the army to stop." Xiao Yu stopped moving forward and continued: "There will be danger going forward, wait here. ”

……

The Demon Base Camp, in the overlapping demon walls, is dotted with tens of thousands of large barracks. A huge magic warehouse would be built every other distance, and there would be more than a hundred warehouses in the entire demon camp, including four in the main warehouse. Of the total warehouses, two-thirds belong to the Dark Clan, and the other one-third to the Abyssal Clan.

A demon of the Abyss clan sneakily walked in the middle of the camp, the camp was so chaotic that no one noticed him, and every time he passed a warehouse, some bone-winged warriors were released, and there were not many about a hundred. This is the third generation of bone wing warriors developed by Wentian City, and its functions and combat effectiveness are even more powerful, especially the energy generated by self-explosion, which is even more earth-shattering and powerful.

The appearance of the Bone Wing Warrior is very similar to that of ordinary demons, but there are countless types of Abyss Demons, and the Bone Wing Warriors can exude an aura similar to that of demons, and no one will notice them.

A small half of the people in the demon camp who are responsible for guarding the defensive enchantment have been killed, and the other half has been transferred, Xiao Yu can lift the defense of a certain area of the demon camp at any time, so that the army can directly break into the hinterland of the demon disaster army unimpeded.
