Yode Town, Green's House, second floor.

After recovering his property and throwing the thief into the prison in the town, Green began to reset the warehouse at home.

Since a large hole had been dug in the basement and it would definitely not be used until repair is completed, Green temporarily transformed an empty room next to the study on the second floor into a warehouse.

"Spirit is constant, and the development of [magic alarm]!" Green clicked a few times in the system interface.

[Spell Constant Spell] is a very important five-ring spell, and it is also a necessary spell for making magic equipment/props. This spell can link certain magic and energy supply devices, thereby ensuring that magic takes effect permanently before the energy supply disappears.

However, it should be noted that each spell constant technology requires the consumption of experience value to "research". The research consumption is 1000*2^n. n is the number of rings that require a constant spell. At the same time, there is a certain probability of failure. The failure rate is related to the number of spell rings, spell skill levels, and intelligence attributes.

With Green's intelligence, you don't have to worry about failing to study a spell in one ring. Even if Green's [Magic Alert] only practiced to level 2.

Green's experience value is 2,000 less. At the same time, Green's [Spell Constant] spell has a new sub-spell [Spell Constant] spell [Spell Constant Magic Alert].

Green closed his eyes and recalled.

The constant of a spell can be used without a magic array, but if there is a magic array, it can greatly reduce the energy loss rate.

"This is just a temporary warning from the safe before, so there is no need for a magic array." Green took out a crystal, put it on the ground, and began to cast spells.

After a brief spell cast.

"Spirit Constant Magic Alert!"

A magic circle appears in the magic crystal, and at the same time, it is centered on the magic crystal. Dozens of thin lines that are invisible to the naked eye block the walls, windows and ceilings. This magic alarm will always take effect until the energy in the magic crystal is exhausted. If anyone enters the room from a place outside the "door", it will trigger the magic alarm.

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

The magic alarm is like an infrared alarm on the earth, just bullying the little thief. When encountering the 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!

In the past, Green was not at home, and there was nothing valuable in the house except some gold coins. Even if he was thieved, it was no big deal. The losses were very limited. But now with Green's return and the spoils brought out from the ruins, there were a lot of valuable things in the house, which greatly increased the attractiveness of those "big thieves"! For those extraordinary thieves who specialize in stealing and lifting traps, such protection is obviously not the same.

For those extraordinary thieves, relying solely on magic alerts is obviously not enough. However, Green has other means besides magic alerts, that is, Mona's manual guard!

Green arranged a magic array in the room, and then placed a fist-sized crystal into the magic array as an eye to provide magic power.

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

"Mona?" The Mona stood on the magic circle and looked at Green with an innocent look on his face.

"Stand and don't move." Green ordered the Mona and the others.

"Mona!" The Mona stood obediently on the magic circle.

"Spirit constant!" Green imposed a spell constant on 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 shine.

After a while, the light was no longer dazzling, and at the same time, a small magic tattoo appeared on Mona's belly.

"Mona?" The Mona touched their stomachs blankly.

"Good luck, it's done in one go." Green checked the situation of Mona, "Now your magic supply can also be provided by this magic circle."

Normally, the magic supply of summoned creatures is provided by the summoner, and the summoned creature cannot be too far away from the summoner. However, this does not mean that the magic power can only be provided by the summoner. It is also completely feasible to add an additional magic supply loop to the summoned creatures.

As a civilization with extremely high attainments in summoning, Anriel has very comprehensive technology in this regard. Green's method is from Anriel's library. This technology also exists in Lisbon, but the exchange price is not cheap, and Green's association points have always been insufficient.

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

"Mona! You are responsible for guarding the room. If someone comes in, blow the whistle immediately."

Mona: "Mona!"

There were ten large wooden boxes in the room, and each box was set up by Green to explode when it opened. Although some things that would not be used at the moment, Green would stuff them into each box in the future. In addition, Green also stuffed stones to increase the weight of the box.

Not only are there magic alarms and traps, but there is also a Mona installed on each box as an artificial sentinel.

"Although it is still difficult to guard against the thief, at least it can be guaranteed to be discovered immediately after being thieves." Green couldn't help but sigh after checking the room, "Before I bought the safe, I can only do this for the time being."

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

Just as Green was holding the communication stone and Mithril silver, she was about to go to the magic workshop to continue her research, the butler Farier suddenly appeared in front of Green: "Master, there are several guests who want to see you."

"Guest?" Green frowned slightly, "Didn't I say that I'll wait for me to go into seclusion?"

Farier: "...yes, master. I'll talk to them now."

After sending the female housekeeper away, Green went back to the study and picked up the paper made by the Magic Mirror. While flipping through the picture, he walked towards the Magic Workshop.

"The next step is to create the 'Remote Sensing Magic Mirror'. As long as the mass production of the Magic Mirror is achieved, the rest will be simple."

The production of magic mirrors is very similar to that of ordinary mirrors. The only difference is that the coating of ordinary mirrors on the glass is a layer of silver on the bottom of the glass, while the magic mirror is a special mixture of mitral and communication stone powder on the bottom of the glass.
