After securing the lightning launcher, Zuo Si quickly turned his gaze to the pile of bottles and cans placed on the wall on the right.

Among them, there are two dozen colorful bottles on the top layer, which clearly exude magical fluctuations.

You don't have to ask to know that these are real magic potions.

The green light that flashes to symbolize life is usually a healing potion.

The darker the color, the more powerful the therapeutic effect.

Even a low-level [treatment of minor injuries] can instantly stop the bleeding and pull back the dying person who only has one breath left.

Trauma only, of course.

If you accidentally injure your internal organs, you will need to use a more advanced healing agent.

As a good thing that can save his life and quickly recover his combat effectiveness after being injured, Zuo Si did not hesitate to sweep away the six bottles and put them into the satchel he carried with him.

Immediately afterward, he took two more bottles of [Antidote Potion], one bottle of Protective [Flame Elixir], and three bottles of [Speed Potion] in case of emergency.

As for the rest that are not needed for the time being, they are directly converted into energy storage and put into the mana pool.

When the energy in the potion is drained, the liquid in the bottle quickly turns a cloudy black-brown or translucent white.

After finishing the potion, Zuo Si carefully opened the dark compartment on the wall in his room, took out a rectangular black wooden box the size of a lunch box and opened it from inside.

Moment!

A whole stack of a dozen scrolls made of magic ink and parchment lay quietly inside.

This is a Scroll Case made with special craftsmanship and magic.

Theoretically, it is possible to store up to twenty-five magic scrolls, as well as some things like notes, maps, and sticky notes.

Not only is it waterproof, but it can be attached to the belt like a kit, making it easy to access when you're in battle.

However, due to the fact that he was limited by his profession and could not cast spells, Zuo Si had no way to copy the scroll by himself.

Scrolls that record low-level magic are better said, and magical items and potions that you can make yourself can exchange with other apprentices.

But the high-level scrolls can only wait for the necromancer Archmage, Asta, to be in a good mood and give him one or two of them.

And transcribing a magic scroll is quite a hassle.

High-level scrolls tend to transcribe one, leaving mages exhausted and unable to cast other spells throughout the day.

As a result, most mages were not in the habit of copying scrolls.

After all, they have the ability to release magic themselves, so they don't need to bother at all.

In addition, these magic scrolls are still indispensable consumables for Zuo Si to make powerful magic items and strange things, and there are still a dozen or so left, which is already quite economical.

You must know that the spellcaster class created by the Els, whether it is a mage or something else, is a typical "blue stripe" spellcaster.

That is, once you master a spell, as long as you have enough magic power, you can release it anytime and anywhere.

Theoretically, if a mage at LV1 can learn and release a ring spell, then a mage at LV9 can release a nine-ring spell, although only one spell per day.

The premise is that the intellectual attributes are sufficient to be able to learn.

On the other side of this portal, the forgotten realm of the magic web, Faeron, is a completely different system.

The latter's spell slot system, although optimized by the magic net to have more daily mana, requires at least level seventeen to learn to master the Nine Rings spell.

And you have to do a lot of preparation before casting the spell.

Through repeated recitations and chanting, the entire spell was forcibly memorized in the minds of the mages themselves in an abstract way that the mages themselves did not know how to describe.

Once cast, the spell is instantly forgotten.

However, the former does not require such a complex process at all.

As long as you have enough mana, you can release any magic you have learned at any time, which is very simple and convenient.

Both magic systems have their own advantages and disadvantages.

But in general, the system of the El magic civilization is more friendly to low-level spellcasters, while the magic system of Feron is more friendly to high-level spellcasters.

As for the portal hidden on the top floor of the entire tower, it was created by Asta in order to make better use of Zuosi's "talent".

It was a massive door frame that was five meters tall and three meters wide, made of magical metal.

The door frame is covered with intricate magical patterns, as well as large expensive and rare gems.

The moment it is infused with energy, it forcibly tears through the space, creating a rift that leads to an unknown place.

Zuo Si only needs to activate the teleportation ability granted by his spark against the rift, and he can establish a relatively stable passage to other magical worlds in a short period of time.

Since the Els have not invented and found a way to immortalize themselves, even the most powerful spellcasters here usually only survive to be between three hundred and fifty and four hundred years old with the help of life-prolonging potions.

Asta is over three hundred and twenty years old.

If nothing else, he will be a withered and lifeless corpse like other dead archmages in a few decades at most.

But the appearance of Zuo Si gave him the hope of eternal life.

Through conversation, the necromancer learns of the existence of the forgotten realm, Feren.

I also know that in Faerun, there is more than one way to make yourself immortal.

For example, lichs and vampires that transform into undead form;

Another example is to deprive thousands of people of their lives at once and bless themselves through legendary magic;

or transform into other elements, spirits, xenomorphic creatures and other special lifeforms that have no upper lifespan, etc.

However, among the many options, Asta is the most eager to transform into a lich.

To achieve this, he first ordered Zuo Si to use his "talent" to help him locate the Forgotten Realm.

Once the location is complete, the portal will open at regular intervals.

Then place some treasures and rare magical items on this side of the door to attract adventurers, travelers, caravans, all kinds of intelligent humanoid and non-human creatures, and even powerful and terrifying monsters on the continent of Faeron.

Once these unlucky people are attracted by treasure and magical items and cross the portal, they are immediately teleported to the dungeon or a special room filled with bondage runes and imprisoned.

Through a series of methods such as coercion, inducement, torture, and memory reading, it didn't take long for Asta to gain a lot of magical knowledge from another world.

As for the female red dragon between the bondages, who had just come of age and was specially used to extract the precious magic material of dragon blood, Vermez, was the only one of the many unlucky eggs who survived.

The rest of the unfortunate ones will be sent to the dissecting table after draining the knowledge and knowledge in their minds, and contribute to the study of necromancy.

In Zuo Si's opinion, Asta is undoubtedly a typical evil necromancer.

Not only does he possess great strength, but he is also very intelligent and extremely cautious.

There is no rush to explore another magical world that is completely alien to me.

Instead, through lure, he first captured some captives to understand the situation on the other side of the space-time gate and collect information.

From beginning to end, there was not the slightest flaw.

You must know that at the beginning, Zuo Si also considered waiting for Asta to arrive at Faeron through that door for the first time, and use the moment when the magic environment suddenly changed, and the other party temporarily lost the ability to cast spells to launch a sneak attack.

Unfortunately, the necromancer didn't give him this chance at all, and the plan was stillborn before it could be implemented.

Later, as Asta learned more and more about Feron, and even learned to transform his "blue bar" into a "spell bit" by touching the magic net, Zuo Si realized that he had lost his chance.

Now, though, Asta is nowhere to be found.

All he had to do was go to the bondage and "talk" with the imprisoned adult female red dragon, Vermes.

Only with the power of this powerful dragon could Zuo Si be sure to deal with the golems and other constructs guarding the upper passages.

Due to the evil, greedy, and brutal nature of the Red Dragon, he had prepared the necessary "bargaining chips" for the "negotiations" several months ago, as well as the backup "means" needed if the negotiations broke down.
