This kind of magic is not only exclusive to liches. Any wizard can use necromancy. However, the necromancy used by ordinary wizards is definitely not as powerful or as wide-ranging as that of liches.

After losing their elemental magic, the liches' expertise in undeath became incredibly powerful.

The undead army summoned by necromancy magic is initially composed of processed undead collected by liches, which is an elite template.

As the war begins and continues, the corpses on the battlefield will be awakened by the liches and become a new army of undead.

This type is crudely made, but the advantage is that there are enough of them.

In large-scale wars, necromancy is indeed a bug-like existence.

As the Lich Master summoned him, the space in his body began to stir. Every wizard has a space in his body to store their wealth.

After the wizard dies, this space will explode.

The more powerful the wizard, the larger the space inside his body.

The space inside the body of the Most Powerful Lich Master is incredibly large, as if it were a demiplane.

This space is gray and lifeless. There is land and sky. In the center of the space there is an old castle, and around the castle is bare land.

And with the call of the Lich Headmistress, white bones broke out of the ground one after another, white fingers tore the land apart, and the undead woke up from their slumber and broke out of the ground.

An endless army of undead emerged from the ground and was summoned into the world by the lich.

"fighting!!!!"

The intelligence of the undead is not high, the only meaning of their existence is to fight, the soul fire burning in their skulls is as strange as a demon, but also as holy as a fairy! !

After the endless army of undead was summoned to the world, they immediately rushed towards the Dark Crows who were lying in front of the energy barrier of the magic city to absorb energy.

The configuration of this undead army is really luxurious. The lowest level is legendary combat power, and there is no shortage of high-level legendary combat power.

With the participation of this undead army, the situation on the battlefield changed immediately. The Academy Magic City, which had been hiding like a turtle waiting to die, now had the power to fight back.

The endless army of undead drove out the endless dark crows, preventing them from absorbing the energy of the magic city of the academy.

The two sides started a fierce battle on the energy barrier!!! "If they continue like this, this war could even last a hundred years!!!" Luther had to admit that he was a little stunned, and he touched the back of his head and said.

"It can only last for ten years at most. If we include the Golem Corps that participate in the war, and wait for our students to grow into legends, it may last for more than twenty years. Because there are no corpses on the battlefield, my Undead Corps will be damaged and reduced in numbers. But the Crows are endless. The Crows are even less afraid of a war of attrition than the Undead Corps."

Said the Lich Headmaster.

"What should we do??? Once the Ravens break through the magic city, won't we all die?" Luther scratched his hair. To be honest, he really didn't want to die.

But now the situation seems to be very bad.

"I know liches are immortal." Luther rolled his eyes. Then his eyes began to roll. Since it was impossible to do anything, he could just run away.

Waiting to die is not Luther Pompey's style.

"The space is blocked. Even I can't escape, let alone you." The Lich Dean saw through Luther's intention to desert and attacked him with a smile.

"Oh." Luther said, then spread his arms and leaned back, lying on the ground in a big letter shape with a thud and closed his eyes.

"Are you waiting to die?" the Lich Dean asked curiously.

Luther opened one eye, and the other remained closed. He said lazily, "You lied to me. If it was true, you would definitely die. Then why are you still struggling? You won't really die anyway. You will be resurrected after a while. I'm not stupid. Since you summoned the Undead Legion to fight the Shadow Crows, you must have a chance of winning."

"I didn't expect that although you have a poor comprehension, your mind is very flexible." The Lich Dean said with a smile, he did not deny it.

Because that's the truth.

What's the point of fighting if you have no chance of winning?

"But it's impossible for you to lie here and wait for the war to end, because my chances of victory lie in your favor." The Lich Dean said with a smile.

"Me? Are you kidding me? What can a low-level legendary like me do?" Luther felt that the other party was crazy. Although the lich had no brain tissue, it still had a head.

"Of course, a low-level legend is useless, but it will be very useful if you grow into a high-level legend. You must know that you are an Earth Knight, the strongest knight, and you are extremely talented. You may be the most outstanding Earth Knight in human history. As long as you reach the high-level legend, you will even be able to deal with ordinary strongest knights."

"What's more, I want to train you to be a powerful knight before the magic city is breached. And repair your bloodthirsty monster. This way, even if we can't win the war, you can still fight your way out."

"You should know that my plan to counterattack the gods is very important, and you are a very important fighting force. I don't want to lose you."

After hearing this, Luther suddenly changed from lying to sitting, staring at the Lich Dean in amazement and said, "I really doubt now whether you have lived too long and have developed Alzheimer's disease. If you say that you can become a high-level legend in a few years, then I am still confident. The difference between low-level legends and high-level legends is that the energy and physical strength are different. High-level legends have stronger control over the laws of the earth. You can overcome this with some hard work. But if you want to become the strongest, that's a problem. And you said that this defensive war can only last for twenty years. Let me become the strongest knight in twenty years?"

"If it's really that simple, then wouldn't the entire universe be filled with the most powerful knights?"

"However, I am very interested in your ability to repair my bloodthirsty monster. Please be sure to help." At the end, Luther stood up politely and bowed deeply to the Lich Dean.

"I have plenty of god-level materials, so repairing your bloodthirsty monster is not a problem." The Lich Dean said with a smile, and then he said: "It is very difficult for others to become the strongest knight, but we are not normal people after all. With my years of knowledge and accumulation, plus your strength, I am very confident that I can make you the strongest knight in more than 20 years."

"It doesn't look like he's crazy or broken. It doesn't look like he's joking." Luther looked up to confirm, feeling a little horrified.

Really???!
