The melee between the races was intense, the smell of blood covering the dirt rising on the ground, and scorching red lasers were unleashed from the pendants worn around the necks of the ostenses, shooting straight at their nearest foe.

Giant bats and black worms screamed, losing their fighting spirit in a matter of seconds.

A red ray missed its target, and after passing thousands of meters, it shot right into the waist of the caveman dragon warrior beside Lin Ye. The latter snorted and immediately pressed to his waist. The waist, which had previously been covered by sturdy dragon blood armor, was now pierced by the laser through a blood hole, and crimson blood flowed out of the blood hole and onto the dry ground.

A ** Julong warrior was slightly injured.

After seeing the power of the laser, the four alien teams immediately retreated.

"Why didn't we ever know they had this technology?" exclaimed a giant bat elder, his face full of panic. His shouts were not answered by the other aliens, but only provoked the panic of his companions.

But of course, there were some elites among them, and some of the black-ringed worms with four rings on their bodies were not afraid of the red laser, and a total of twenty of them jumped on the city wall, causing a commotion among the birds. In addition to the worms, the three-legged crabs in their sturdy armor are even more powerful, and their mirror-like shells bounce off the lasers that shoot at them, making them completely unharmed. They thrust their claws into the relatively soft walls and climb up little by little.

The Cancer's body was used as a siege tower, and all sorts of aliens hid behind the Crab, dodging the red lasers that came from all directions.

The cunning snake men hid under the city walls, raising their muskets and aiming upwards, and if any bird dared to show its head, it would be shot away. In less than five minutes, the panicked alien team regrouped and found their place after paying the price of 500 dead lists.

Just as they were fighting each other, Lin Ye had already led the team around the back of the main city. The number of birds guarding the back wall was very scarce, and most of the main force was transferred to the side of the main wall. The rest are some old, weak, sick and disabled fighters, just to observe whether there is a sneak attack on the back.

"Let's go!" Fireclaw keenly grasped the moment, knowing that now was the perfect time to infiltrate the city.

"Warriors, we have come here for three missions! The first mission is to find and kill the Great Elder of the Bird, the second mission is to find the technology for making gem runes, and the third mission is to take away as many treasures as possible in the city!" Fireclaw roared, and the caveman dragon warriors and flowers and birds present nodded their heads in response.

Lin Ye spread his wings and set off a strong wind on the ground. The storm swept through the sand and dust and blew it onto the city walls, briefly blinding the birds.

Led by ten squad leaders, the warriors were divided into ten squads, and with the help of the cover of the grass on the ground, they came to the foot of the battlements very smoothly. The troglodyte warriors exchanged glances, and after receiving the signals of flowers and birds in the sky, they immediately began to climb the city walls. They pulled out the fingers hanging from their waists and plunged into the cracks in the walls, and climbed up little by little.

Lin Ye took the flowers and birds into a dark cloud in the sky, closely monitoring the every move of the birds on the city wall. The latter were staring left and right with wide eyes, the red necklace around their necks glistening, a long-accumulated strength looking for a target to vent. If the bird discovers one of the dragons, then Fireclaw's plans will be completely exposed. They can't withstand the concentrated fire from these powerful red lasers.

Unlike usual, Rocco the Bird changed his previous lazy appearance, and was seriously patrolling the battlements, it was already in its twenties this year, and served as the chief of the city guard of the western city wall in the main city of the Bird, which was equivalent to the age of middle and old age among the birds of the bird. Rocco carefully inspected the city walls, and it did not dare to slack off in the slightest. The battle is going on in front, and if the other party is unable to break through the defense of the main city for a long time, then he will definitely think of other ways, and at this time, the probability of a sneak attack in the rear of the city is very high.

"The walls are normal, there are no marks of scratches. Rocco muttered to himself. He looked at the entire section of the city wall, which was nearly a kilometer long, and on the long wall stood fifty dutiful ostenses, each less than twenty meters away from each other, and they focused their attention on the city walls, and would not let go of any suspicious creature.

Rocco counted the number of bird warriors and turned his gaze back to the outside of the city.

"This damn sandstorm!"

The sandstorm set off by the forest night has not dissipated, and this sandstorm still carries a thick smell of water vapor and grass and trees torn apart by sand, blocking the keen sense of smell of the birds. Rocco took the sandstorm for granted as a natural phenomenon and didn't think much of it. Still, he could smell a strange smell from the sandstorm.

"What does this smell like? I've never smelled it before. ”

Rocco sniffed carefully, trying to discern the source of the scent. Immediately after that, Rocco's ears tipped and it heard the sound of a sand storm scratching and metal thrusting outside the walls.

"Something!" Rocco immediately raised his alarm, poking his head out of the city. But just as it was probeing, a sharp finger tiger happened to plunge into Rocco's throat head-on, stabbing and sealing the throat!

Captain Julong jumped on the city wall, and at this time, Lin Ye once again increased the power of the sandstorm. The frenzied sand swept into the city by the storm, and the osstry warriors on duty on the city walls were obscured by the more violent sand, and even the feathers on their wings were difficult to see when they stretched out their wings.

The two warriors closest to Rocco were the first to notice that something was wrong, but before they could make a move, the two ** dragons suddenly jumped out from the edge of the city wall, killing them.

The sandstorm lasted for three minutes, and after three minutes. The warriors on the city wall have been replaced by cave-dwelling dragons, and the original birds have been turned into corpses, neatly lying in their former positions. They stood on the walls and began to discuss how to approach the center of the city.

The city of birds looks a little similar to the Cité Soleil, with its structure visible from the high walls.

Less than thirty seconds later, there was some agitation behind the walls. A team of giant bats and black-ringed worms were slipping along the wall behind them, trying to sneak up on them, just as the dead Rocco had thought in his heart.

Their concealment skills are so poor, coupled with the surveillance of the flowers and birds in the air, they are spotted by the caveworms under Fireclaw's men as soon as they approach the city walls.

"Leave them alone, our decapitation is important!" Fireclaw roared, and immediately jumped into the city with the troglodyte warriors. Along the way, they hide themselves from the birds and civilians, and sometimes they are also discovered. Every time they were about to sound an alarm, the troglodyte warriors were quick to deal with them before they were exposed.

Giant bats emit sound waves to scour nearby creatures, only to find that the birds on the walls are dead. The two giant bat elders descended to the city wall with their own hands, and the corpses under their feet looked very shocking.

"Who did that?" said the elder in a trembling voice. As far as it can remember, no creature can inflict such sharp penetrating damage on an ostrich.

"Could it be that there is another group of forces besides us!?" A Black Ring Worm Elder suddenly had a flash of inspiration and said excitedly, "This is really great! Hahaha! Now the Bird Civilization is bound to perish!"

Just after the caveman departed, a patrol of the Bird Warrior climbed the wall and saw that the wall was full of the corpses of the Bird Warrior. It looked up, and at the same time saw the alien contingent on the city walls. It immediately opened its mouth and shouted: "There is an enemy attack!!

Its shouts were sharp and intense, and the sound quickly spread throughout half of the main city, and the news soon reached the ears of the Great Elder Gada.

"It's time to turn on that!" Gadda screamed, reaching out to control the power of faith to shoot at the floating red gem.

The giant red gemstone suspended in the very center of the city spun rapidly, and a regular quadrilateral quickly emerged from its case. The quadrilateral fluttered aimlessly on the case, obviously a rune, but at the moment, it was as if it had life, and it quickly surged with vitality.

A red barrier quickly shot out from the inside of the city wall, one in each of the four directions. They soared straight into the sky, and the four barriers merged together to form a very conspicuous urban barrier.

The aliens on the city wall were all stopped outside by the enchantment, and the birds fighting on the city wall were also intercepted, they wore red necklaces, they could enter and exit from the barrier, and the morale of the birds was stronger when they saw the enchantment rising, in addition to using the necklace to shoot lasers, they kicked their legs and joined the hand-to-hand combat with the aliens again.

And a group of warriors from the Phoenix Civilization had already entered the main city, and this enchantment was obviously too late for them.

A three-legged giant crab had climbed the city wall, its body occupying two-thirds of the width of the entire city wall, and it looked at the red barrier rising in front of it with disdain, and at the same time raised the giant claw in its hand and smashed it into the barrier.

Its body was directly bounced off by the strong impact, and it lost its balance and fell off the wall. And the enchantment that was supposed to be shattered under the destruction of brute force did not move at all!

"Impossible!" the three-legged crabs under their feet pricked up their eyes, unable to believe what they were seeing. The giant crab that smashed into the enchantment just now was one of the strongest among them, and a clawed claw could easily clip a piece of steel with a thickness of one meter, and could smash a three-meter-deep crater in the ground, each of which was equivalent to the deadly impact of five tyrannosaurs.

However, even if this red barrier had encountered such an attack, it only rippled slightly at the point of impact, and after a few seconds, it regained its calm.

Lin Ye, who was flying in the sky, also saw this scene below.

The white faith that lingered in the city quickly melted into the red gem like smoke, which seemed to become a bottomless pit after opening the barrier, endlessly devouring the power of faith around it, and even so fast that a belief vacuum was formed around it.

"Gem Rune - City Barrier! is one of the advanced manifestations of Gem Rune, and if the host obtains this technology, it can also use City Barrier. It takes a lot of faith to maintain the City Barrier, which is why the Great Elder of the Bird has been slow to open the City Barrier. ”

Hearing the system's words, Lin Ye's desire for gem runes became even stronger in his heart.

After activating the city barrier, the scales of victory began to tilt in favor of the birds. Whenever the Bird Warrior is under siege from several alien races, it can hide in the barrier with its legs slightly back, reverting to the unfavorable situation before the battle began. And the red necklace on their necks emitted red lasers at the enemy all the time, bringing extremely painful casualties to the aliens.

In this siege, elders began to die. A giant bat elder was covered in blood holes left by the laser's penetration. Because of the bruises all over its body, its movements became extremely sluggish, and finally because it couldn't dodge, its heart was shot through by a laser, and it died on the city wall. The other alien elders were also wounded, and although they had killed a lot of bird warriors, their own situation was not optimistic.

Every leader is an extremely valuable asset to civilization, and if the battle continues, I am afraid that many more elders will die in battle.

Compared to the Elder Bird, the Bird Civilization with only ten leaders left can give birth to leaders much faster than other alien civilizations, and they are not afraid of death, and would rather lose 800 of their own lives than injure 1,000 enemies. Once they succumb, the last thing that awaits them is extinction, and the entire Bird Civilization will cease to exist.

The alien teams were losing ground and the defending ostrich warriors began to fight back. This crusade against the Bird Civilization seems to have failed.

But in the city, Fireclaw has led the troglodyte dragon warriors to the door of the Owl Palace, where there are two Birds of Bird, they are wearing jewel armor, and each gem on the armor is inlaid with very strange and different runes, each rune has a different ability.

Fireclaw sensed layers of threat from them.

"Gem armor is a derivative of gem runes. The Bird Guard specializes in protecting the Great Elder, and the gem armor on it has many gem runes, although the effect of each rune is not as powerful as the red gem floating in the center, but the overall performance is extremely strong. It can greatly improve the combat and defense capabilities of the bird. “
