When tens of thousands of undead stormed the city walls, and when the corpses of the undead piled up into mountains and turned into natural siege ramps, the loss of the first line of defense was almost a foregone conclusion.

But the Silent City's side was no less slow to react.

While the front-of-the-line Flame Blade troops began to retreat, entering the second wall to continue their long-range support on the front line, the ranged troops of the Silent Blade threw away their bows and crossbows, drew their swords and fought the undead in close combat, buying time for the evacuation of friendly forces and the support of reinforcements.

In addition, the melee troops waiting in the rear naturally did not let the gap be opened, and every time a soldier of the Golden Flame Blade withdrew, a soldier from the Blade of Silence or the Demon Army would step forward to fill the gap he left behind, knocking down the undead who stepped on the wall, and temporarily filling the hole in the defensive line.

At this moment, the cannon on the second high wall roared again, but the target became a mountain of corpses piled up under the city wall, and the cannonballs rushed into the depths of the corpse pile with strong momentum, and the violent explosion blew countless corpses away, leaving a deep cannon crater.

As the artillery cleared the pile of corpses, the pressure on the city walls was also lighter, and although the undead could cling to the walls to attack, they were far less efficient than rushing up the walls with corpses.

Just when everyone's hearts were slightly relieved, the last afterglow of the sun was finally blocked by the mountains, and a terrible cry came from the distant sky.

Thousands of black shadows gathered together, like a dark cloud, flying towards the defense line of the Silent City under the cover of night, and the soldiers of the Golden Flame Edge turned their guns, but the results were few, but the pressure on the front line was tight.

"Bone Eagle? No, skeletal vultures? ”

These flying spirits possess the body and skull of an eagle, and have a long, thin neck covered with a broken membrane on the wings of the bones, dotted with a few decaying feathers.

"Looks like this card is going to be used early."

Isu shook his head, a card flipped in his hand like a butterfly, and beside him, there was a female legendary powerhouse, who was staring at the two undead monarchs in the distant sky with a solemn face, but ignored Ysu's words.

Isu was not annoyed, he and this female legend were also acquaintances, so he naturally knew the character of the other party, but looked at Fei Qi next to him.

Fei Qi was the commander-in-chief of the northern battlefield this time, he glanced at the skeleton vultures hovering in the sky, and nodded: "If you can kill this group of vultures, you won't lose." ”

"Hey, what a coincidence, I think so too!"

Isu smiled slightly, and the card in his hand suddenly hovered in front of him, and countless mana crystals instantly evaporated, turning into a light blue mana torrent pouring into this card.

[Radiant Rain, Spell/Special, Red Bronze, X/5/120, Effect: Infuse mana crystals to rain a radiant rain within the specified area, restore the physical strength and injuries of all creatures within the range, and deal divine damage to all undead within the range. Note: Each injection is no less than 2000 mana crystals, and the range of action is related to the number of mana crystals injected. 】

[Shelter the Living, Banish the Dead]

A strategic card!

This card was used once when Isu evacuated the ruins of Labrinsian, but at that time, he only consumed a minimum of 2000 mana crystals, and a rain of light fell within a radius of 20 meters, and the effect was not as powerful as expected, each drop of light rain could only restore a little physical strength, and the healing of injuries was also extremely limited, more than half the effect of a rookie's healing hand.

But on the battlefield, this is enough!

Think about it, every drop of light rain can restore the physical strength of a warrior to attack one or two times, although the density of light rain is relatively sparse, but it can also ensure that everyone can be recovered by light rain at least once per second, and the duration of five minutes is enough to restore a warrior's physical strength to peak state!

And the healing effect is also lasting, and the effect may not be obvious in a short period of time, at most it slows down the bleeding rate, but what if it lasts for five minutes? The cumulative healing effect can even restore a seriously injured warrior to combat effectiveness again!

And this time, Isu burned 30,000 mana crystals in one go, and even the cards were shrouded in a layer of light blue aura!

Waiting, when the mana crystals within 30,000 burned out, Isu did not cast the [Radiant Rain], but stared at the skeletal vultures in the air.

Waiting, as the skeletal vultures flew over the tide of the undead, Izu was still waiting.

Await......

It wasn't until the skeletal vultures flew over the Silent City defenses, folded their wings and began to dive, that Izuku suddenly let go of his grip on the cards, and a golden light rose into the sky, staining the otherwise dark night sky with a pale golden shimmer.

In the next second, the light exploded!

The pale golden raindrops ignored the howling night wind and fell straight downward, but in the blink of an eye, they were above the skeletal vultures!

When the first drop of light rain came into contact with the skeleton vulture, a miserable howl instantly enveloped the night sky, and under the shroud of light and rain, all the skeleton vultures twisted in mid-air, and the dry bones shrunk tightly into a ball, like a ball of bones, whirling downward, smashing on the ground and shattering into pieces of broken bones.

And what reached the ground faster than the skeletal vultures were the rain of light that held down the plates of Newton's coffin.

In the shroud of light and rain, the warriors were refreshed, their originally somewhat tired bodies were instantly rejuvenated, and the wounds on their bodies were slowly healed under the nourishment of drops of light rain, and even a trace of darkness drilled out of the wounds and evaporated into nothingness in the light rain - this is the unique death qi of the undead.

On the other hand, the undead are a different story.

These undead are tireless, not afraid of death, and naturally have no pain, but in the shroud of the light rain, these undead have twisted and curled up into a ball, and the light rain is like a strong acid, corroding a large black mist on the body of the undead, and finally, the undead in the light rain have turned into dry bones, and are beaten by the raindrops that follow, shattered into a handful of ashes.

Thus, for the first time, the word fear appeared in the dictionary of the lower undead.

In the face of the rain of light like a curtain of light in the sky, all the undead stopped in place, even if the two undead monarchs roared angrily, they could not let these undead take a step forward, and even, more undead chose to retreat - they would rather face the wrath of the undead monarch, and would rather their souls be tormented by the undead monarch for eternity, rather than be destroyed by divine power in the rain of light.

In the end, under the deterrence of this brilliant rain of light, the two undead monarchs reluctantly chose to face the reality, and gave up the siege with tens of thousands of undead, and retreated to a crypt three kilometers away.

The undead, too, have learned to be afraid.
