Yod Town, Green's House, second floor. Pen "Fun" Pavilion www.biquge.info

After recovering his property and dumping the thief in the town's jail, Green began to re-establish the warehouse in his home.

Since a large hole had been dug in the basement and would certainly not be usable until it was repaired, Green temporarily converted a vacant room next to the study on the second floor into a warehouse.

"Spell constant, research and development [Magic Alert]!" Green clicked a few times on the system interface.

[Spell Constant] is a very important five-ring spell, and it is also an essential spell for crafting magic equipment/items. This spell allows certain spells to be linked to the power supply device, ensuring that the magic works permanently until the energy supply is gone.

However, it is important to note that each spell constant technique costs experience points to "research". The research cost is 1000*2^n, n is the number of rings that require a constant number of spells, and there is a certain chance of failure in research, and the failure rate is related to the number of spell rings, spell skill levels, and intelligence attributes.

With Green's intelligence, he didn't have to worry about failing to research a ring of spells - even if Green's [Magic Alert] was only level 2.

Green's experience is 2000 points less, and at the same time, a new sub-spell [Spell Constant: Magic Alert] has been added to Green's [Spell Constant] spell.

Green closed his eyes and recalled.

The constancy of the one-ring spell can be done without a magic array, but if there is a magic array, it can greatly reduce the energy loss rate.

"This is just a temporary alert before the safe is delivered, and there is no need for a magic array." Green took out a crystal, placed it on the ground, and began to cast a spell.

After a brief cast.

"Spell Constant・Magic Alert!"

A magic circle appeared in the magic crystal, and at the same time, with the magic crystal as the core, dozens of thin lines invisible to the naked eye blocked the walls, windows, and ceilings. This magic alarm will remain in effect until the energy in the magic crystal is depleted, and will be triggered if anyone enters the room from outside the "door".

Looking at the thin lines in the space, Green sighed: "This can only prevent small thieves, and it is useless in front of professional thieves." ”

The magic alarm is like an infrared alarm on the earth, and it's just a little thief, and when you encounter the kind of professional thief in the TV series, the effect of the magic alarm is really worrying. And in the world of Io, that kind of professional thief is everywhere!

Before, Green was not at home, there was nothing of value at home except for some gold coins, even if he was robbed, it was not a big deal, and the loss was very limited. But now, with the return of Grimm and the loot removed from the ruins, there are many more valuable things in the house in an instant, and the attraction of those "big thieves" has greatly increased! For those extraordinary thieves who specialize in theft and disarming traps, this protection is clearly the same as not.

For those extraordinary, relying on magic alerts alone is clearly not enough. However, Green has other means besides magic alerts, and that is Mona's artificial guards!

Green sets up a magic circle in the room, and then puts a fist-sized crystal into the magic circle as an eye to provide magic power.

After that, Green grabbed twelve Mona and placed them in the twelve circles on the magic circle.

"Mona?" The Monas stood on the magic circle and looked at Grimm with an innocent expression.

"You stand still." Green instructed the Mona.

"Mona!" Mona obediently stood on the magic array.

"Spell constant!" Green applied a spell constant to the magic circle.

The magic circle emitted a white glow, and at the same time, the Mona standing on the magic circle also began to glow.

After a while, the light ceased to dare, and a small magical tattoo appeared on Mona's stomach.

"Mona?" Mona touched her stomach blankly.

"Luckily, it did it once." Green checked the situation of the Mona, "Now your mana supply can also be provided by this magic array. ”

Normally, the mana supply of minions is provided by the summoner, and the minions cannot go too far from the summoner. However, this does not mean that the summoner can only provide mana, and it is perfectly possible to add an additional mana supply loop to the minions.

As a civilization with a high level of attainment in summoning, Anriel has a very comprehensive skill in this area, and the method used by Grimm is from Anriel's library - this technology is also available in Lisbon, but the exchange price is not cheap, and Green's guild points have been in a state of insufficient state.

After building a new mana supply station for the Mona, Green placed the Mona on several chests in the room and gave them a whistle.

"Mona! You are in charge of guarding the room, and if anyone comes in, blow the whistle immediately. ”

Mona: "Mona! ”

There were ten large wooden chests in the room, and each box was set up by Green to explode as soon as it was opened. Some things that are not needed at the moment, but will be used in the future, are stuffed into each box by Green, and in addition to this, Green also stuffs stones to increase the weight of the box.

Not only are there magic alarms and traps, but each chest has a Mona placed on it as an artificial sentry.

"It's still hard to keep a thief at bay, but at least it's guaranteed that a thief will be discovered immediately." After checking the room, Green couldn't help but sigh, "Until the safe is bought, that's the only way to do it for the time being." ”

After arranging everything, Green walked out of the room with a few communication stones.

Just as Green was about to go to the magic workshop to continue his research with the communication stone and Mithril, the housekeeper Farier suddenly appeared in front of Green: "Master, there are a few guests who want to see you. ”

"Guest?" Green frowned slightly, "Didn't I say that whatever happened would wait until after my retreat?" ”

Fariyah: "...... Yes, master. I'm going to tell them. ”

After sending the housekeeper away, Green went back to the study and picked up the paper made by the magic mirror, and while flipping through it, he walked towards the magic workshop.

"The next step is the production of the 'Remote Sensing Magic Mirror'. As long as the mass production of the magic mirror is realized, the rest will be simple. ”

The Magic Mirror is made very similar to a normal mirror, with the only difference being the coating on the glass - a normal mirror is coated with a layer of silver at the bottom of the glass, while the Magic Mirror is coated with a special mixture of Mithril and Communication Stone powder at the bottom of the glass.

"It's a bit of a hassle, but ...... Still within the scope of acceptance. ”
