Li Yan, who had just arrived, looked at this scene with a complicated look in his eyes.
Strictly speaking, the Immortal King's undead army was brought to this world by him.
Although the Immortal King himself is also growing slowly, even if he does not strengthen himself, I am afraid that he himself will be able to awaken this army thousands of years later.
But it's different now.
Now he has strengthened the Immortal King, making his evolution process faster.
It was himself who made this army of the undead come to this world in advance.
Just as Li Yan was secretly asking himself, a voice of surprise suddenly came from the distant sky, above the huge fortress.
"Reinforcements!!"
"Look! It's reinforcements!!"
"Reinforcements are coming!!"
The sound of surprise immediately affected the soldiers in the entire fortress.
They all looked back.
Li Yan, who was watching the battle from high in the sky, also looked behind the fortress.
really.
Behind the fortress, a troop of 100,000 gray heavy-armored cavalry was slowly approaching.
This group of heavy armored cavalry seemed to have been carefully selected. Although a hundred thousand people were marching together, their sounds were extremely regular and orderly, without making any messy sounds.
Not only the war horses, but also every soldier was covered in gray heavy armor.
Li Yan saw that all the knights in this heavy armored cavalry were holding black long-handled war hammers.
These war hammers are very heavy just by looking at them.
Being hit by these war hammers may result in comminuted fractures at least, or the entire person will be smashed into pieces.
For undead creatures.
This kind of war hammer that can easily crush bones will definitely be more advantageous than long swords and lances.
Li Yan did not expect that reinforcements would arrive before the Immortal King attacked the city.
After the huge fortress that cuts off the mountain range, there is a huge town.
Within the town, the residents knew that the undead army was coming and had all evacuated.
As the opponent's reinforcements arrived, the Immortal King seemed to be ready in front of the fortress. The red soul fire in his eyes danced, the Netherworld horse neighed, and the Immortal King raised the flaming black giant sword in his right hand and swung it forward violently.
"Roar--!"
Following the movements of the Immortal King, the light of souls emanating from the eyes of the entire undead army suddenly beat violently, and they then let out soul-shaking roars.
Then an army of millions of undead finally launched a charge against the fortress.
It was beyond Li Yan's expectation.
These undead soldiers are not as fragile as they thought.
With the signal of the Immortal King's attack, the blue soul fire in the eyes of these undead soldiers also turned into a violently beating red soul flame.
Then the leading undead soldier in front of the formation was agile and rushed out. He leaped directly into the air and flew up to the fortress.
"Pfft!"
Suddenly, an Imperial soldier who was about to load a giant crossbow was stabbed through the heart on the spot.
The light of life in his eyes quickly disappeared, and a weak light of life merged into the body of the Immortal King.
"Bang! Bang bang!"
When many imperial soldiers were surprised, there were several more sounds of armor falling to the ground.
More and more undead soldiers jumped onto the barrier.
In Li Yan's impression, ordinary skeleton soldiers should be able to kill with a single blow, which is a walking experience value.
However, almost every skeleton warrior summoned by the Immortal King has the strength of Silver rank.
Their movements are agile and emotionless, and their armor covered in gray mist is extremely tough.
Soon, this fortress leading to the interior of the empire was completely captured.
Blood was gurgling, and the imperial soldiers who had been cheering to celebrate the arrival of reinforcements now all fell into a pool of blood.
Facing this terrifying undead army, their own spirits collapsed first, and thousands of soldiers in the entire fortress were all killed.
The fortress gate was lowered, and the Immortal King slowly moved forward with his army and entered the fortress.
Then, under Li Yan's unexpected gaze, the Immortal King jumped off his horse, raised his giant sword with both hands, and thrust it into the ground.
"boom--!"
A burst of impact spread, and with the arrival of the Immortal King, the decay continued to spread, and the entire fortress was stained with a layer of gray.
The flesh and blood of the Imperial soldiers who fell to the ground quickly decayed, as if they were feeding back to the earth.
Not long after, they turned into withered skeletons, and even the silver armor rotted into gray-black.
It was only then that they were given new life by the Immortal King.
"Buzz——"
The eyes of these imperial soldiers slowly lit up with the light of indifferent souls.
They turned into withered bones and slowly stood up with old swords in their hands.
They were originally here to defend the empire.
Transformed into thousands of undead soldiers.
In the distance, in front of the slowly approaching heavy cavalry regiment, a strong man wearing rhino heavy armor looked indifferently at the fall of the fortress and prayed in a low voice:
"The Empire will remember you."
The strong man spoke slowly.
Then he looked back behind him, and in a thick and rough voice without fear, he loudly shouted to his soldiers:
"The Imperial Mage Statue has given us protection!!"
"Warriors!!"
"Guard our land!!"
"Drive these demons away without a single one left!!"
The big man's voice resounded throughout the sky, and behind him, a hundred thousand heavy-armored knights immediately shouted in unison.
"Expelled!!"
"Expelled!!"
At the same time, on the hill fortress, the city gate facing the inside slowly opened, and the imperial soldiers who had just been recruited by the Immortal King filed out. With the roar of the undead, they rushed towards the heavy armored cavalry team attacking from the opposite side.
.
As these heavy armored cavalry charged forward, Li Yan could feel the roar caused by their horses' hooves, which seemed to make the whole land tremble.
Seeing the fallen imperial soldiers coming towards them, the 100,000 heavily armored knights seemed to have been mentally prepared.
"Warriors!"
"With the war hammer in our hands!!"
"Let them rest in peace!!"
The leader of the knights shouted loudly, and struck down the black hammer in his hand extremely quickly.
"Click——!"
The sound of cracking bones echoed, and with one blow from the commander, a skeleton soldier charging in front of him was completely smashed to pieces.
The two armies suddenly fought together.
This time, the Immortal King's side did not have such devastating strength.
This heavy cavalry was all elite warriors, and they suppressed the undead army that was charging towards them.
At the same time, Li Yan, who was watching the battle from a high altitude, discovered that this group of heavy cavalry seemed to be wrapped with a layer of black energy.
The end of the black energy connection is in the direction they came from.
When Li Yan raised his head, the Immortal King seemed to have noticed something.
The nearly three-meter-tall dark horse neighed, stepped on the fire of hell, and rushed out towards the top of the barrier carrying the Immortal King.
The Immortal King held a pitch-black sword in his hand, and as if he were in an uninhabited land, the pitch-black horse leaped out from the top of the barrier and flew directly over them under the gaze of countless imperial knights.
"boom--!"
The war horse landed, and the dark flames spread, carrying the Immortal King towards the rear of the 100,000 heavy cavalry.
Upon seeing this, the commander of the cavalry regiment immediately said loudly:
"not good!!"
"His target is the Imperial Mage Statue!!"
"Return to defense quickly!!"
The battle started for a long time, but no one noticed that Li Yan, who had just arrived, was watching the battle high in the sky.
If Li Yan takes action, he can end this battle.
But if you want to stop the battle, you must kill the Immortal King yourself.
Otherwise, as long as the Immortal Throne still exists, this undead army will definitely come back.
But after understanding this world, Li Yan already knew the predecessor of the Immortal King.
