The air is where the battle is fiercest, and the one-sided situation is gone - the vampires have joined the fight. A large number of vampires were summoned by the corpse witches hiding in the distance, and they made up for the small number of bipedal wyverns, and rushed to the city walls in a steady stream.

Vampires are evil undead creatures. They look like a combination of a human and a bat, with bat-like wings. Freshly summoned vampires are usually emaciated and can gain more power by sucking the blood of living creatures, and are said to become more powerful at night.

A large number of vampires circled rapidly in the air not far from the city walls, waiting for an opportunity to attack the defenders on the walls. Individual vampires are much worse than Wyverns, but with their large numbers, small targets, and agile size, elves' ranged troops are unable to effectively strike at vampires.

Not far from the city wall to Vane's right, a two-legged wyvern had taken advantage of the chaos to break through to the vicinity of the city wall, letting out a roar. An elven archer panicked and took two steps back, giving the Wyvern a chance to breathe, and the already scarred Wyvern swooped down on the wall.

"Captain, do you want to activate the ......?" the adjutant asked, apparently noticing the situation on the wall on the right, with a worried face.

"Walden, everything is going according to plan, and that's reserved for the last guy to come. Leonard stared into the distance, seemingly unconcerned about what was happening on the walls. After a pause, he muttered to himself, "Do those guys in the advance army really care about Salento's life or death......

It seems that the people on the watchtower have been noticed, and there are more and more vampires circling around the watchtower, they are not attacking, and they are patiently waiting for their chance.

With a finger of the staff in Vane's hand, the fireball flew out and crashed into a vampire's body, instantly burning it black and falling down in black smoke. Others quickly joined the fray, with the tower's defenders becoming more ferocious and the nearby vampires dwindling.

At that moment, a piercing scream came, which made people's eardrums hurt. Not far away, a giant vampire appeared in the vampire group, its green face and fangs, its gray body with scarlet markings, at least twice the size of ordinary vampires, this is a vampire king.

"Whoosh!" an arrow burst through the air and headed straight for the Vampire King, blue lightning leaping from its body, leaving a twisted trail in the air. The vampire king, however, rushed straight towards the crowd on the watchtower as if he hadn't seen it.

The arrow collided with the Vampire King, or the Vampire King crashed into the arrow to be exact, and it seemed to be faster than the arrow, and the arrow pierced through its body. The vampire king's body froze slightly, and dark green juice erupted from its body, but it continued to accelerate regardless of it, and in a blink of an eye, it reached the battlement of the watchtower and grabbed the shoulder of the elf who had shot the arrow just now with its two sharp hind claws.

Everything happened in a single breath, and no one expected the vampire king to be so violent, and when everyone came back to their senses, the elven soldier had been taken to the sky by the vampire leader. The vampire king tilted his head, his huge fangs gritting into the elf's neck, blood gushing out. The other vampires went crazy and scrambled for the blood they spilled.

The bloody scene made Eth's face pale, and Vane and the others also had their hairs standing on end. Leonard's face was gloomy, and he drew his rapier in his right hand and looked at the vampire king.

The vampires were still frantically sucking blood, and the ugly bodies stained with blood and the piercing screams were chilling.

The sound of "zilazila" sounded for a moment, and a flash of blue lightning jumped on the blade of Leonard's hand. The blue lightning was furious, making a slight explosion sound from time to time, and seemed desperate to break free.

The Vampire King is sucking blood to replenish his energy, and the blood causes the wounds on his body to heal at a rate visible to the naked eye. Leonard raised his rapier slightly, pointed it at the vampire king, and the next moment the blue lightning was freed.

The vampire king's body in the distance suddenly froze, his gray skin covered in lightning, and sparks burst out with a "crackling" sound. Immediately after that, the Vampire King's body exploded in a small area, emitting thick smoke and falling straight down like a bundle of lit straw.

The blue lightning didn't stop there, and it climbed up to a nearby vampire at an imperceptible speed. Even the blue lightning that the vampire king was scorched with electricity, too cruel for the poor vampire to struggle, and it also turned into a corpse with black smoke and fell down. Blue lightning scurried through the vampire horde like a grim reaper, and in the blink of an eye, all that was left in the air was a pile of smoking, charred black objects that were rapidly falling downward.

Vane was secretly frightened. The magic cast by Leonard is a mid-level light magic - chain lightning, which is an improved version of forked lightning that overcomes the problem of short fork lightning cast range and concentrates energy into a single lightning beam to shoot. Each time the chain lightning hits an enemy, it will continue to jump to the nearest enemy until it runs out of energy. But it is unheard of to be able to attack dozens of targets in a row without a large energy decay.

Leonard lowered his arm, and a remnant of lightning flickered on the tip of his sword. He looked at the adjutant and said in a serious tone: "Walden, now you are in charge of the command of the defenders of the city wall, and you must prevent the strange beast from crossing the city wall. Remember, don't activate the Magic Railgun until the last minute. I'm going to assist the Duke now. ”

Leonard's silver suit began to melt and recoalesce into a disc-shaped flying machine. He stood up and looked back at Vane and the others, "Adventurers, I don't know how you came to Salento City. The whole of Salento has now fallen, and the last remaining city is in an unprecedented crisis. You guys do it for yourselves. With that, the anti-gravity vehicle carried Leonard towards the distant city wall.

The pressure on the watchtower was relieved for only a moment, and some vampires gathered again, and the sky in the distance was filled with countless black dots. No one spoke, didn't even have time to think, and everyone's heart felt like a stone had been pressed against it—in a war of this magnitude, no matter how powerful an individual could be, it would be difficult to influence the outcome.

Due to the increase in air power, the army of alien beasts on the ground had advanced to within a hundred meters of the city wall, and some of the nimble alien beasts had even dodged heavy firepower and were rapidly climbing up along the city wall.

At that moment, a yellow flare was fired from the watchtower not far to the left, and the flare flew high into the air with yellow smoke. A moment later, a rumbling sound came from below the city walls, and at the same time, an earth-shattering roar rang out!
