There's no way, it's hard to run outside, and the mage city-state will never let him leave, so there's only another way.

The base is built at the edge of the underground space, built according to the stone wall, digging into the stone wall from the edge of the room, and the excavated soil is all collected in the palm space, and then the stone is closed to plug the cave that has passed.

The stones are then turned into soft mud by using fossil to mud spells, and then hammered hard to deform and expand the soft mud, and then turn the mud into stones, and the swollen stones get stuck in the unevenness caused by the excavation.

Don't ask how to solve the problem of breathing, the space in the palm of your hand is so large that it can hold enough air for them to survive for more than a week.

In a week, how can you dig a depth of two or three kilometers.

With the complex structure of the underground, there are passages of different sizes everywhere, and as long as you are not too lucky, you can always dig through.

Of course, it is not a big problem if you can't dig it up within a week, and for Li Qing, who has the bloodline of the Ancestor Ancient Dragon, breathing is not necessary.

Breathing is a habit, but not a must.

In the mage city-state, eight hours after Li Qing left, the mage tower that monitored him realized that something was wrong, and immediately sent people over to check, only to find the empty temporary military camp.

Several hounds circled back and forth in the barracks a few times, not only did they not find anything, but they were frightened when they entered the study where Li Qing was staying.

When Li Qing left, it was cleaned very cleanly, and the stone slabs were also tightly fitted, and they were filled to the brim, even if he used a hammer to test it, the sound of the stone wall he excavated was no different from other stone walls.

A group of mages used spells to plow the entire barracks, including the stone slabs on the ground, and found no anomalies.

It wasn't until the angry old mage behind him used an earth-shaking technique to disregard the taboo of the underground space that the stuck stone pillar was dislocated and abnormally revealed.

But it is not easy to catch people.

They can't dig stones like Li Qing does, they need to bring in a large number of mages to keep using fossils to soften the rocks with mud, and then send people to dig them.

The fossils of ordinary mages are mud and have a limited impact volume, so they need to be constantly cast and excavated, and the combined efficiency of a group of mages is not as high as that of Li Qing and Long Fa.

In eight hours, Li Qing had already dug hundreds of meters deep, and it was basically impossible for them to catch up.

Core Mage Tower, Stargazing Deck.

After receiving the news of Li Qing's disappearance, Speaker Canovino sat in the center of the observatory for a long time without saying a word, and several middle-aged and elderly mages who were his students were also silent when they stood outside the circle of the observatory, and the observatory fell into an eerie silence.

At this time, Speaker Canovino was older than before, his twilight was heavier, and his body was more rickety.

I don't know how long later, Canovino suddenly let out a long sigh, and a hoarse voice sounded on the stargazing platform:

"Why didn't he say a word and leave? Actually, we can still talk about it! ”

There was silence for a while, and the hoarse voice sounded again:

"I have no choice but to lose this opportunity!"

All the teachers and students were silent, and they all knew what the teacher meant.

"So, let's get started!"

The thin hand took out a scroll from his sleeve and spread it out, and through the starlight, he could see that there were a few words written on the scroll - Lich Transformation Ritual!

Time passed, and soon a week passed, and Li Qing kept digging forward for a whole week, and the total length of the excavated passage was four or five kilometers, but he did not find any end.

So he didn't have a head iron, quickly changed direction and dug to the left.

After digging for five days in a row, another three or four kilometers, the exit was still not reached.

"So thick?"

Li Qing was a little speechless.

Fortunately, at this time, he no longer needed to breathe, and others would have suffocated to death.

I can't help it, just keep turning and changing directions.

In the following days, he kept changing directions and digging forward, and before he knew it, a month had passed.

And on the day of the month of his hard work, the mage tower in the central core of the mage city-state suddenly exploded violently, and the huge explosion fire broke through the wall of the mage tower and erupted.

Just when the entire city was looking at the center of the city in disbelief, the four major elemental energy balls on the surface of the central mage tower suddenly shrank inward and merged into the tower, and after a while, a surging death aura erupted from it, surging in all directions like a tide.

The city-state town hall near the Mage Tower was instantly flooded, and then a large number of mages working in the town hall fled, many of whom shouted in disbelief:

"It can't be!"

But the tide of death did not stop because of this, but followed them at super-fast speed.

The mages blessed themselves with defensive spells, but the civilians of the city-state did not have this ability, and they were swept by the tide of death, and soon fell to the ground with blue faces.

After a while, the corpse that had fallen down began to shake violently, and soon staggered to its feet.

The upheaval in the city shocked the War Lord apprentices gathered outside the city, and they were even too shocked to know how to react for a while.

"What the hell is this horse-stepping?"

Zhang Chunyi held his head in his hands, his face full of shock and dazedness.

The front was fending off the army of natural disasters, and the backyard actually caught fire, which made them overwhelmed for a while.

Fortunately, there is a quick response, and everyone will be notified immediately on the Divine Area Network:

"The bad news, Speaker Canovino, one of the three speakers of the mage city-state, has completed the lich transformation ceremony, has officially transformed into a lich, and seized control of the core mage tower and cast the nine-ring spell Undead Scourge."

"Canovino estimates that he has transformed this spell into a hero spell, and after the bonus of the core mage tower, its power is not inferior to that of a legendary spell."

"Everyone immediately summoned the front-line troops to retreat and gather in Zhong Haiying's Divine Domain."

Zhang Chunyi immediately came to his senses, quickly gathered his subordinates, and ordered his heroes to go to the front line to summon his troops to fight on the front line.

However, the mutation of the city-state has affected the frontline battlefields, and today's Scourge Legion's offensive is particularly ferocious, and with the withdrawal of a large number of mages subordinate to Speaker Canovino, the front line is on the verge of collapse.

When many of the War Lord's apprentices gathered their troops to retreat, the already barely supported battle line completely collapsed, and countless undead troops slaughtered at the entrance of the passage and began to attack the city.

If it had been placed in the past, at this time, the mage towers in the city could exert their strength and directly bombard the undead army at the entrance of the passage.

In the past, it was with the combined efforts of more than twenty mage towers to suppress the army of the undead.

But this time, there was a change in the city, not only did the core mage tower not make a move, but it was also suppressing other mage towers, resulting in no one to support.

The high walls lasted only one day before they were destroyed head-on by an army of undead.

A large number of seven or eight meters high, or even ten meters high, rushed to the city wall, hammering continuously with a chain hammer, smashing the city wall alive.

As soon as the city wall was broken, a large number of undead spirits poured into the underground space where the city-state was located.

The War Lord apprentices gathered in the Zhong Haiying Divine Domain saw this scene, and their faces turned green.

"Horse-stepping"

"What should I do, run away!"

"Where to flee, the only exits have been sealed, and the portal has been closed."

"What then?"

"I remember that there were several small passages, and the large troops would definitely not be able to enter and exit, but they could accommodate small groups of people in and out."

"Didn't you say it earlier, where?"

"On the other side, we need to take a detour."

"Then lead the way."

At this time, someone asked:

"What about me?"

Everyone was suffocated, and a few people said:

"Give up the Divine Domain!"

I was speechless for a while.

No one paid attention to him, and no one could pay attention to him at this time, and the troops of the people quickly gathered outside the city, preparing to make a detour to the other side of the city-state.

Halfway through, the undead scourge, enhanced to Legendary level, has covered the entire city and spread beyond it.

This interrupted their march and forced them to retreat further into the subterranean space.

Most of the more than 100,000 inhabitants of the entire city-state were civilians, and they had no power to fight back in the face of legendary necromancy, and all of them were transformed into zombies on the spot.

Even mages are not immune, and mages below the third order have been forcibly transformed into corpse witches before they have time to escape the area of influence of legendary spells.

Mages above the third order will only have a chance to escape if they are discovered early, and their reaction will be a little slower, or they will find the mutation too late to escape, which will be a dead end.

The effect of the legendary spell soon extended to the outside of the city, and the moment it came into contact with the Scourge Legion that had already broken through the passage wall, the submerged Undead Legion suddenly stopped moving, and then it was forcibly controlled and launched a counterattack against the Scourge Legion behind.

Two different armies of the undead fought outside the city.

The Scourge Lord soon discovered the anomaly, and the subsequent undead legions did not move forward, but assembled at the broken wall at the entrance of the passage and waited.

Time passed, and the magic effect of the Scourge of the Dead extended throughout the underground space before stopping, and then slowly faded until it disappeared.

Then an army of pure zombies converged at the gates of the city-state and swarmed towards the entrance of the passage.

The two undead legions collided head-on and tore each other apart.

Where can a simple zombie beat the army of the Lord of the Scourge, a dozen abominations nearly ten meters tall rushed into the zombie group, rampage, and no one could stop them.

However, there is a large number of corpse witches behind the zombie army, and under the control of the lich Canovino, they have begun to cast various spells to support.

These corpse witches are all transformed from serious mages, and most of the spells they used in their lifetimes can still be cast, including the fireball technique, which is a battlefield magic skill.

A large number of fireballs flew into the battlefield, blasting to pieces.

In addition, as time went on, many of the mage towers in the city gradually fell, and a large number of mages either surrendered, or actively transformed into lichs, or necromancers, and then joined the battle.

Hundreds of thousands of zombies, supported by many corpse witches and necromancers or lichs, firmly held the undead legion at bay.

Li Qing dug a hole in the ground for more than a month, turned left and right, and finally hollowed out the earth, appeared somewhere in the middle of the stone wall of the underground space, stretched out his head, and saw the chaotic battlefield of the undead below.

He was stunned for a long time, and he was stunned for a long time before he realized that he was digging left and right in the depths of the closed earth, and he actually turned around and dug back again.

However, although he recognized that he had dug it up, he was still confused at first.

It's only been a month, and this mage city-state has become a city of death, and there are few living people left in the entire underground space.

The position where he appeared was the edge of the stone wall more than a thousand meters above the ground, unable to reach the sky, not to the ground, and there was no place to settle around, completely suspended in the air, and hundreds of thousands of undead below were fighting hotly, and no one found his existence.

There are quite a few flying undead units on the Scourge Lord's side, but after he came out, he immediately restrained his breath, and occasionally the undead flew by and did not find him.

The vast majority of undead units rely on soul fire to sense their surroundings, not their eyes.

As long as all the aura on his body is completely constricted, it will not exist like a stone to the undead, and he will not notice it even if he passes by.

The destruction of the mage city-state surprised Li Qing, and he saw the possibility of fishing in troubled waters.

Although the mage city-state has transformed the entire city into undead, and there are more than 100,000 soldiers in an instant, the quality is not good, and it can be defended temporarily with the mage tower, but once it is consumed, there is a high probability that it is not an opponent.

Although the Disaster Hero's side has a huge advantage in troops, there is a high probability that he can win in the end, but when he is consumed in the end, his strength will definitely be greatly damaged.

At that time, Li Qing will have a chance.

If you can really fish in troubled waters, no matter which side of the head you grab, the harvest will be absolutely rich.

Therefore, after the excitement, Li Qing slowly calmed down, restrained his breath, and sealed the entrance of the cave, leaving only a small hole.

Next, it's a matter of waiting.

And the changes in the underground space were as he expected, the two armies of the undead began to consume each other, and a steady stream of skeleton zombies turned into powder in the war.

But just after the war had lasted for five full days, more than twenty lichs or necromancers above the transcendent rank gathered on the stargazing platform, the top of the central core tower of the city-state.

Above the observatory is a large circle of lichs, where the lichs are standing in one position, chanting incantations.

Standing in the center of the magic circle was a tall lich with a luxurious robe and a staff in his hand, but with three heads, if Li Qing was here, he would recognize that the head in the center was Speaker Canovino.

The three-headed lich stuck his staff in the center of the circle, and the skull in the center was chanting.

At this time, the soul fire in the eye socket of the skull on the right erupted from the eye socket, and shouted angrily:

"Canovino, you won't succeed, you're going to die."

And the head on the left said in a calm voice:

"Canovino, you're too impulsive, we can pay the price to get the dragon vein first, relatively speaking, becoming a dragon vein mage is a better choice than becoming a lich."

The spell in the center of the head paused, and he said in a deep voice:

"But he's gone, and I don't have time."

The skull on the right roars angrily:

"You can choose to become a lich, but you are not qualified to make decisions for the entire school, you have killed the people who have supported us, you have turned your back on the school and our people."

The left head also speaks in a calm tone:

"Canovino, you're wrong."

The central skull replied coldly:

"I'm not wrong, only by transforming into the undead, can we have enough soldiers to resist natural disasters, and only by transforming into the undead can we not be afraid of undead spells."

He shouted:

"Time will tell, I made the right choice."

The staff in his right hand slammed into a slam blow, and a circle of invisible ripples exploded, and the soul fire in his pupils surged violently, and the powerful power instantly suppressed the left and right heads.
