From the capture of the necromancer, Alec got a general idea of the castle.

The city in front of you is called Blackstone City, and it is a typical underworld city. The plane where Blackstone City is located is the sphere of influence of the underworld, but there are not no living people in the castle, in fact, ordinary people account for the vast majority of the castle, but the ruling class of the castle is either a necromancer or a direct undead...... This is a common phenomenon in the Netherworld, where these necromancers control the castle while they are alive, and when they die, they will continue to rule as undead.

The necromancer in front of him is an inconspicuous little nobleman in Blackstone City.

He went out of the city at this time with the idea of fleeing for his life as soon as possible -- when the main army of the devil came to the city, it would be too late to escape for his life.

Getting the message he wanted, Alec thought for a moment and slashed the necromancer with a single sword.

The undead were silent for a moment, and then went madly at him.

But Alec was prepared.

The necromancer is a living man, and the living know fear, so he will escape from Black Rock City and will also surrender under the threat of the sword...... But as soon as the wizard dies and the undead lose their restraints, they will start attacking all living things without reason.

If Alec is a warrior class, this situation is really a bit troublesome.

But for a spellcaster, especially one who is familiar with the urine nature of the undead, it is easy to fool these skeletons.

Under the gaze of hundreds of thousands of undead, Alec's body blurred for a moment, and then a tattered skeleton appeared in front of the undead. The skeletons that rushed up were a little stunned, and they looked at the strange skeleton with empty eyes, but they couldn't see the flaw in the end...... It didn't take long for the pile of bones to disperse again.

Alec, in the form of a skeleton, took the opportunity to walk towards Blackstone City.

The side entrance to Blackstone City has been closed, but due to the necromancer, there are no guards here.

Alec didn't use spells, and the movement of spells was too loud and could cause unnecessary trouble. He turned the lava sword in his hand into a jagged shape, and it took a lot of effort to break through the iron door.

The streets of Blackstone City were so quiet that not even a single undead could be seen.

But what made him feel strange was that there were many broken buildings in the city, and it was obviously caused by the fire spell. However, the devil's army is now blocked out of the city, unable to enter Blackstone City, and because of the existence of the Dark Witch Tower, all their spells are blocked by the spell barrier on the city wall, and it is impossible to cause damage to the buildings in Blackstone City.

This is a flaw in the world of memory.

It is likely that Netherf entered Black Rock after the Devil's army had won.

Alec thought for a moment and didn't go out.

This had little effect on him.

Because he entered the Black Rock City in Neself's memory, the undead in this city had long since been cleaned up by the devils. The biggest flaw in the memory world is the chaos of the timeline, judging from the progress of the devils' siege, it is likely that Nesef will enter Blackstone City three to six days later. Alec arrived a few days early, but the city was still full of post-war scenes...... Although the devil is still desperately attacking the city.

Netherf hadn't traveled much, and many areas of Blackstone City were shrouded in white mist, the edge of the world of memory. If Alec encounters a threat that he can't face, he can escape the world of memory by jumping into these areas.

Of course, if he did, he would waste the engram.

…………

Along the street, Alec approached the center of Blackstone City, where the majestic Dark Witch Tower had been reduced to ruins, and some vague demons were searching for spell materials in the ruins.

Not here......

Alec paused here, and the road before him split into two, one leading to the outer wall and one to the cemetery.

He turned and walked towards the cemetery.

Considering that the undead are mostly bones, the probability of having something good in the cemetery is much greater than in the city walls.

The figure of the devil flashed in the street from time to time, but soon disappeared in front of Alec, and as he approached the cemetery, two skeleton warriors popped out...... Alec took care of the two outwhelmed creatures with two swords, then strode into the cemetery, and after slaying a few more ghouls, a dozen zombies, and a bunch of skeletons, he finally found the target of his trip.

The entrance to a catacomb.

After solving the trigger trap on the tombstone, Alec strode into the tomb.

The extent of this tomb is large and dark.

A flame appeared in his hand.

By the light of the flames, he finally saw the inside of the tomb, and in the hall, dozens of coffins were neatly placed, most of which had been opened, and the treasures inside had been taken...... Of course, these coffins are not all finances, there are some deadly traps, and there are several devil corpses in this hall, some of them have been frozen into ice, some have been burned to black charcoal, but most of all, they are dried corpses.

This is most likely the effect of the undead [Energy Absorption].

Of course, spells like Life Suck can have the same effect.

Alec walked through the hall, and soon a gray wall appeared in front of him.

The wall had been blasted open, and behind it was a secret room...... Of course it was empty, and the wealth in the secret room had long been looted by the devils, and not even a bit of gold was left for Alec.

Strange, where is the news left by Neself?

Alec walked around the tomb a few times, and he even struggled to remove a sarcophagus, but the coffin was underneath a solid pavement, not an imaginary chamber. He then slammed the ground and walls with a probing spell, but the result was disappointing, as there really really was only one chamber in the tomb, and it had already been ransacked.

Could it be that the valuable memory is on the side of urban construction?

Alec found it incredulous.

The city walls have always been the place where the fighting was fiercest.

The demons fought desperately to open a breach in the city walls, while the undead desperately attacked the devils and tried to crush their attempts...... After a great battle, the walls were reduced to ruins. Under the bombardment of various powerful spells, many times the situation is like this: after the battle is over, the winning side cannot find the location of the city walls, and they can only judge the location of the walls according to the size of the enchantment of the witchcraft towers in the city.

In the gloomy darkness of the tomb, Alec did not wrinkle.

The flames jumped in his hands, and without noticing, a ball of flame burst across the vines above his head.

Alec was taken aback, then waved his hand and extinguished the flames.

It wasn't until this moment that the wall covered with magic patterns appeared in front of him.
