Engrams are not 100% safe to use, and in many cases, memories stored in them are quite dangerous.

The reason is simple.

Crystals are simply stored memories, and when users use this crystal, they create a 'world of memory'. There will be a lot of irrationality in this world, and there will be a lot of ambiguity, and generally speaking, the farther away from the center of memory, the more ambiguous the world will be, and the more unreasonable things will be...... If the user dies in the memory world, the mind will be traumatized at least and the soul will collapse at worst.

…………

Alec is taken by the engram to a barren plain.

He woke up in a pile of corpses.

The faces of these corpses are very blurry, which is the blind spot of Nessef's memory, he does not deliberately remember these dead people, so they are also blurry in the world of memory. However, Alec still received useful information from the appearance of these corpses, most of which were demons, but there were also the remains of demons and undead.

Dimensional battlefield.

Alec pushed a corpse away and stood up.

The plains were quiet, with nothing but the darkness of the earth and the roar of magic in the distance.

Alec knew that what Netsuf wanted to tell him was on a distant battlefield, but the sight of that day made him hesitate - it was the scene of a large-scale legion battle. Although in the world of memory, the power of mass spells will be weakened, no matter how weakened it is, it is not something that Alec can fight.

He crept closer to the battlefield.

Two legions shrouded in mist appeared before him.

Nesef did not remember the appearance of the legion, but he did remember the flags of both sides, one of which was a long whip covered with spikes, and the other was a black raven.

The succubi of hell and the corpse witches of the underworld are at war.

Alec cautiously bypassed the battlefield and headed for the black castle not far away.

Approaching the castle, he could visibly perceive that the world of memory had become clearer, which was a good thing, indicating that Alec was getting closer to the message he was looking for...... But at the same time, obstacles began to appear in his way. Wandering undead began to appear near the castle, and the lowest level was naturally the dry bone skeletons, these rotten undead were more fragile than ordinary people, and even an adult man could easily deal with them.

Alec, however, had some trouble.

Because behind these undead was a tall castle, and he saw many guards on the city walls, the worst of which were skeleton guards, and the strongest were black warriors in armor...... If the castle's guards are alarmed, he is likely to be besieged by a large number of undead.

That's when it happened.

A small group of demons came from far and near, and they soon exchanged fire with the undead defending the city.

The strength of this team is very strong, Alec looked at it from a distance, the succubus led by it was a lord-level master, and the flames in her hands shot out like raindrops, blasting large holes in the hard black rock. The two Fire Demons under the Succubus Lord are high-level demons, and the weakest of the rest of the subordinates are also middle-level demons...... Of course, the undead defenders who fought with them were no less weak, and under the leadership of the Black Knights, a large number of corpse witches appeared on the city walls, and then the raid quickly turned into a storm.

The spells of succubi and lichs loom over the battlefield.

Alec, who was not far away, frowned.

Nine times out of ten, the message that Netsuf was going to tell him was in the castle of the dead (the closer you get to the memory center, the clearer the world becomes, and if Neseph's message has nothing to do with the castle, then the castle will be blurry. ）…… But the problem for Alec is that he doesn't know how to get into the castle.

Alec recalls carefully.

He crawled out of the pile of corpses, and in this world, he brought in what should have been the experience of Nesef.

Nesef went through a battle at the time...... He may have been seriously injured, but he was only supported by the life force of the high-level devil...... If this speculation is true, it means that it is unlikely that there will be too much fighting in the future.

In other words, Nesef definitely did not rely on strength to fight into the castle.

There must be a way to do it.

Alec avoided the battlefield and made his way around the towering walls of the City of the Dead.

As he walked, the world became clearer and clearer, and cracks and debris began to appear on the black earth.

Soon, the side door of the castle appeared in front of him.

A team of undead is coming out of the castle. Alec didn't dare to get too close, after all, he didn't know if this was the route that Netsuf had taken to enter the castle, although the world clarity was a clear guide, but who could guarantee that Netsuf must have entered from here? If this was his route out of the castle, the world was just as clear, and if Alec rushed to it, he would probably lose his life in vain.

The team wasn't too long, and it wasn't long before Alec saw the heart of the team.

A necromancer in black robes.

Alec didn't dare to use a probe spell.

Wizards are classic spellcasters, ordinary probing spells will only startle snakes, and some cunning spellcasters will even falsify spell rewards to lure explorers into their own traps...... Although there was no specific information, Alec decided to make a move, and the necromancer's clothes gave a hint, and he saw a delicate pattern on it.

Nesef had been in close contact with the robe, so he remembered the world to create such a specific pattern.

- [Silent Enchantment]!

- [Phantom Legion]!

- [Lava Armament]!

Nesef is a melee class, and out of caution, Alec has chosen a similar style of combat.

A demon army of dozens of people rushed towards the undead.

The wizard at the head was shocked, he raised his hand and wanted to use the spell, but he couldn't recite the spell under the silent enchantment (the spell itself is not a necessary condition for building a spell, and not being able to speak will make it difficult and slow for the wizard to cast spells, but it will not make them lose their ability to cast spells), plus Alec is paying close attention to the necromancer, the black spell energy has just begun to gather, and a spell countermeasure is thrown directly into the necromancer's face.

The spell was interrupted.

At the same time, the Legion of Illusions also rushed into the ranks of the undead, and the tall figures of the devils passed through the undead without causing any casualties.

"Illusion?!"

Most of the undead breathed a sigh of relief, but the necromancer who was the leader was extremely nervous.

With illusion and silent enchantment, an idiot can guess what Alec wants to do.

A large number of undead began to move closer to him, and hundreds of skeleton warriors formed a 'human wall', protecting the necromancer in the middle.

A crimson figure flashed among the undead.

The necromancer turned his head and saw a three-meter-tall demon, wrapped in crimson flames, and a hideous and strong body made of lava. The two-meter-long lava heavy sword in its hand crushed more than a dozen low-level undead in just one sweep.

"High-level Flame Demon?!"

The sorcerer in a panic has long forgotten the difference between a demon and a devil, or he doesn't know the difference between the two...... In the eyes of the undead, demons and demons are mostly the same thing. It only noticed that the fire demon in front of it exuded the aura of high-level life, and it was killing him like a bamboo all the way, and all the undead in its path were crushed (of course, this is also an illusion)......

It made a stupid decision.

The wizard gave up the protection of the undead and fled with a stream of urine.

In a panic, it even forgot to throw a [Dismantling Magic].

Alec swept away several undead with a single sword, then took a deep breath and chased after the necromancer with his sword...... In the rush to kill, the illusions on his body were quickly dispersed, and the huge fire demon phantom disappeared in front of the undead. Fortunately, after all this time, he had caught up with the necromancer, and under the latter's frightened and ashamed gaze, he easily shattered the bone shield and put his sword on the wizard's neck.
