Isu waited in Wind Helmet City for seven days.

However, the days of waiting are not boring, in the past few days, in addition to doing a few errand tasks, I took the opportunity to walk around the city of Helmet, in addition to figuring out the terrain of Helmet City, I also went to the "house of antiques in Callisto" a few times, under the guise of "appreciating historical objects", I thoroughly touched the antique house of Krim, of course, the main thing is to remember the appearance of Krim clearly, so as not to know who to arrest when I get it.

Speaking of which, if Isu hadn't known that Kerim was the murderer early on, otherwise, he would never have thought that this middle-aged uncle, who looked very capable and had an infectious smile, would be the murderer of multiple murders!

Callisto Krim was in his forties, with a few laugh lines at the corners of his eyes, and a well-groomed mustache that gave him a bit of a lean look, and everyone had the impression that he was a very kind "weirdo".

Of course, the so-called "weirdo" is not because of Krim's strange behavior, in the eyes of everyone, Krim is an out-and-out good person, and the reason why everyone thinks he is a little weird is because of his hobby - collecting antiques.

You know, the so-called "troubled gold, prosperous antiques", this sentence is not fabricated out of thin air, in the war years, sometimes you can't even eat, who is in the mood to collect antiques? Sometimes a centuries-old unique product is not even worth a small yellow croaker.

Compared with the earth, although the purchasing power of gold in the world of Nairn is lower ((1)), the reason is the same, such as today's chaos, Krim, as a rich man, not only does not hire guards to protect his own safety, but scatters money to collect some antiques that no one wants, isn't this weird thing?

However, Isu knew that Krim's motives for collecting antiques were definitely not that simple.

According to Isu's understanding, Krim is not really a collector with no combat power as he appears, but a spellcaster with a lot of actual combat experience!

That's right, Isu found out when he visited Kelisto's antique house, the arrangement in Klim's curios, is definitely arranged by a mage, and even Isu also found a hidden floor door, which vaguely exudes mana fluctuations, no matter how you look at it, it is a magic secret door, if this kind of door is not broken by brute force, then only know the corresponding key mage can open.

Combined with some clues that have appeared in the game, Isu can easily deduce the identity of the caster of Crim, and moreover, Krim is also an experienced caster, or at least, an experienced caster.

In addition to doing tasks and going to Krim's antique house to step on points, Isu also contacted Shadow Blade, which was stationed in Windhelm City, and with the help of Shadow Blade, he hooked up with Jorefu, the archsteward of Ufrik, although not very close, but at least he was familiar.

After that, it's a simple wait.

In the past few days, Isu has condensed nearly a thousand mana crystals in one go, and after being promoted to a mage apprentice, Isu's spiritual power has increased by more than two times, and now it takes less than ten minutes on average to condense a mana crystal, if you use "Psychic Resonance" to strengthen the connection with the card while condensing mana crystals, this speed will increase by a few points.

And what really made the speed of Yi Su's condensation mana crystallization earth-shaking change was that he could now use meditation instead of sleep, saving the time for sleep to recover his mental power, if he concentrated on condensing spell crystals all day, he would be able to condense more than two hundred mana crystals in almost one day.

In addition, Izu's "Psychic Resonance" has also made great progress, and the [Fireball Technique]'s Psychic Resonance has reached its limit, and the "Reading Time" has been reduced to 0.1 seconds, completely becoming an "Instantaneous Spell".

The hidden attributes of several other cards were also known to Isu when they were fed back.

The hidden attribute of the [Underworld Deed] is called 'Offset', and the effect is that when returning to the present world from the house of the Soul Stone Mound, the location where the portal can be opened can be moved in a certain direction according to the card holder's wishes, and the distance is directly related to the strength of the holder, with Ysu's current strength, it can only move about three meters.

Although the distance of three meters is a bit weak, but in time, when Isu's strength increases, the distance that the portal can move may reach tens, hundreds, or even thousands of meters, and at that time, this attribute will be more useful.

If the hidden attribute of the [Underworld Deed] is high growth potential, then the hidden attribute of the [Armed Emblem] is what surprised Ysu the most.

According to Isu's perception of cards, all cards have an "effective distance", centered on himself, when the artifact, creature, and even spell effect summoned by the card will lose its effect after leaving him at a certain distance, and the card artifact and card creature will directly cancel the summon and return to the blank card, and the spell effect will be directly invalid.

However, the hidden attribute of [Armed Emblem], 'Augmented Reality', breaks this rule.

This 'augmented reality' is naturally not an AR effect, but after Isu pays some additional mana crystals, the equipment blessed by the armed emblem can exist for a certain amount of time after leaving the "effective distance".

The activation cost of [Armed Emblem], that is, the cost of blessing the armament, is five mana crystals, and after testing, the consumption of 'augmented reality' increases with the increase of the effective time, and the additional consumption of ten mana crystals can make the summoned equipment exist for an additional day, and the additional existence of two days requires the consumption of twenty-five mana crystals, and three days is fifty, four days......

Four days, because it took too long and the mana crystals consumed were a bit too much, Isu was reluctant to do the experiment.

As for [Loyal Knight], this card that has followed Ys for the longest time, and the hidden attribute makes Ys a little shocked.

[Loyal Knight] itself has a card trait called Loyalty, that is, Willy takes the protection of Yth as his supreme creed and obeys any orders of Ys, and the hidden attribute of this card goes even further.

"Loyal Guardian: Passive effect, when a card creature is present, when the card holder takes fatal damage, the damage will be transferred to the card creature and restore the card holder to its best condition."

When Isumo recited this attribute, he had a bad premonition in his heart, this attribute, no matter how you look at it, is it a flag, isn't it......

Isu shuddered.
