When tens of thousands of undead spirits hit the city walls like a tide, and when the dead bodies 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 reaction of the Silent City was also not slow.

The Golden Flame Front troops at the forefront began to retreat and entered the second high wall to continue to provide long-range support to the front line. However, the Silent Blade's long-range troops threw away their crossbows, drew out their swords and fought with the undead in close combat, buying time for the evacuation of friendly troops and the support of reinforcements.

In addition, the melee troops waiting behind will naturally not let the gap be opened. Whenever a soldier from the Golden Flame Blade evacuated, a Silent Blade or a soldier from the Demon Army will step forward to fill the gap left by him, and knock down the undead who stepped on the city wall, and temporarily fill the loopholes in the defense line.

At this time, the second cannon on the high wall roared again, but the target turned into corpses piled up in mountains under the city wall. The shells rushed into the depths of the pile of corpses with powerful momentum. The violent explosion blew up countless corpses, leaving a deep cannon pit.

As the artillery cleared the pile of corpses, the pressure on the city wall was also lighter. Although the undead could climb onto the city wall to attack, the efficiency was far less than rushing up to the city wall with corpses.

Just as everyone was relieved, the last afterglow of the sun was finally blocked by the mountains, and a shrill cry came from the distant sky.

Thousands of black shadows gathered together, like a dark cloud, flying towards the defense line of Silent City with the cover of the night. The soldiers of the Golden Flame Front turned their guns, but the results were very few, which made the pressure on the front line tightened.

"Bone Eagle? No, skeleton vulture?"

These flying undead have the body and skull of an eagle, and have a thin and long neck. The bone wings are covered with a layer of broken membrane, dotted with several decaying feathers.

"It seems that this card will be used in advance."

Yisu shook his head, a card flipped and shuttled like a butterfly in his hand. Aside him, there was a female legendary strong man staring at the two undead monarchs in the distant sky with a serious face, but instead ignored Yisu's words.

Yisu was not annoyed. He was also acquaintance with this female legend. Naturally, he knew the other party's personality and looked at Feiqi next to him.

Feiqi is the commander-in-chief of the northern battlefield this time. He glanced at the skeleton vultures hovering in the sky and nodded: "If we can kill these vultures, it will be no loss."

"Hey, it's a coincidence, I feel so!"

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

[Rain of Rain of Light, Special Spells, Red Copper, 512o, Effect: Inject mana crystals, drop a rain of Light within the specified range, restore the physical strength and injuries of all creatures in the range, and cause sacred damage to all undeads in the range. Note: The mana crystals injected each time are no less than 2ooo, and the range of action is related to the number of mana crystals injected.]

【Protecting living beings and expelling death】

A strategic card!

This card was used once when Yisu evacuated the ruins of Labrin Xi'an. However, at that time he only consumed a minimum of 2ooo mana crystals, and a light rain dropped within a radius of twenty meters. The effect was not as strong as imagined. Each drop of light rain could only recover a little physical strength, and the healing of the injury was extremely limited, which was more than half the effect of a healing hand cast by a rookie.

But on the battlefield, this is enough!

Think about it, every drop of light rain can restore the warrior's physical strength to one or two attacks. Although the density of light rain is relatively sparse, it can also ensure that everyone can recover at least once light rain every second. The duration of five minutes is enough to restore a warrior's physical strength to its peak state!

The healing effect is also continuous. The effect may not be obvious in a short period of time. At most, it will slow down the bleeding. But what if it lasts for five minutes? The accumulated healing effect can even restore a seriously injured warrior to combat effectiveness again!

This time, Yisu burned 30,000 magic crystals in one breath, and even the card was covered with a light blue mist!

Waiting, when the 30,000-plus mana crystals were burned out, Yisu did not cast [Rain of Glory], but stared at the group of skeleton vultures in the air.

Waiting, when the skeleton vultures flew over the undead tide, Yisu was still waiting.

wait……

It was not until the group of skeleton vultures flew over the defense line of Silent City, gathered their wings and began to dive, that Yisu suddenly let go of his hand holding the card tightly, and a golden light soared into the sky, dyeing the originally dark night sky with a light golden light.

The next second, the light bursts!

The raindrops scattered with light golden light ignored the howling night wind and fell down in a straight posture. In the blink of an eye, they came to the sky above the skeleton vultures!

When the first drop of light rain came into contact with the skeleton vulture, a miserable howling instantly enveloped the night sky. Under the skeleton vultures, all the skeleton vultures twisted in the air, and the dry skeletons tightly collapsed into a ball, like a ball made of bones, falling downwards, smashing on the ground and shattering into pieces of broken bones.

And what reached the ground faster than the skeleton vulture was the light rain that pressed down on Newton's coffin board.

The soldiers were energetic in the rain of light, and their originally tired bodies instantly rejuvenated. The wounds on their bodies slowly healed under the nourishment of drops of light, and even a trace of darkness emerged from the wound, evaporating into nothingness in the rain of light - this is the unique death aura of the dead body of the undead.

On the other hand, the undead is a different scene.

These undead are tired and fearless of death, and naturally there is no pain. However, under the cover of the light rain, these undead moves twisted and curled up into a ball, while the light rain is like a strong sour, corroding large pieces of black mist on the undead's body. In the end, the undead in the light rain turns into dry bones, and are beaten by the raindrops that follow, and breaking into a handful of ashes.

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

Facing the glorious rain of light like a hanging light curtain in the sky, all the undead stopped in place. Even the two undead monarchs roared and urged them, they could not let these undead move forward. Even more undead chose to retreat - they would rather face the rage of the undead monarch, and would rather be tortured by the undead monarch forever than be destroyed by the sacred power in the rain of light.

Finally, under the intimidation of this brilliant rain of light, the two undead monarchs had no choice but to face the reality, and with tens of thousands of undead gave up siege, and once they retreated, they retreated to a crypt three kilometers away.
