"Smack."

Returning to the house, Lin Tuo first inspected the No. 3 sandbox, and the "environmental ether concentration" showed an increasing trend again.

The scorched earth of Haizhou was covered with heavy snow, then thawed and became vibrant again.

According to past experience, if nothing happens, at least in "a few hundred years", there will be no more problems, but in preparation, Lin Tuo feels that he still has to find a way.

Prepare for the next possible "spirit invasion".

Well, now, whether he wants it or not, every once in a while "spiritual invasion" has become a task that he needs to solve.

Conversely, as long as the effects of the disaster can be controlled, this is not necessarily a "good thing".

"According to the information I have, both the ether and the supernatural power are inextricably linked to the 'spirit world'.

It can be judged that if you want to continue to evolve, you will inevitably have more dealings with spiritual forces in the future...... The invasion of the spirit realm may also help me deepen my understanding of the occult realm. ”

While thinking, Lin Tuo raised his hand, and the "Spiritual Origin" obtained after killing the "Head of the Haizhou Faction" appeared in his palm......

According to the system prompt, it is still in the "unstable state" and cannot be resolved.

However, referring to the "Nightmare", Lin Tuo is still quite looking forward to it.

"I don't know if I can absorb ......"

Darkly, Lin Tuo opened the drawer and put it in, ready to wait for it to be truly "stable" before making observations.

At the same time, I took out a "silver bracelet" that I bought on the Internet a few days ago from the drawer, deftly removed one of it, put it in the palm of my hand, and came to the sand table.

Switch to "Observation Mode" and carefully drag one of the rings of the bracelet with a clone and place it in the mountain.

After a while, he heard a slightly low roar at the gate of the front hall of the martial arts hall, and Lin Tuo's gray eyes lit up again, retracted his clone, and pushed the door out.

After passing through the martial arts arena, when I came to the front door, I saw a huge silver lump several meters high lying on the ground.

If memory serves, this is the first time he has used the magnification rules of the sand table to perform this kind of operation on the mountain.

Pinched it with his hand, well, it's very soft, the purity is good, and Lin Tuo showed a satisfied smile on his face.

Then he dragged the silver nugget into the patio and tore a piece back to the study.

"Now the materials are complete."

Exhaling lightly, Lin Tuo's eyes became serious.

With blood as the medium and sterling silver as the substrate, it's time to start making.

Yes, Lin Tuo is going to make something, to be precise, an "instrument...... According to the name in the spell books, the full name is "Mana Distribution Sensor".

Originally, it was an instrument for mages and scholars to conduct research in World No. 2, which can be understood as experimental equipment...... What it does is simple:

Disturbances in the magical environment within a certain range can be detected.

Based on his previous experiences, Lin Tuo found that the "Spirit Invasion" was not traceless.

Whether it's an "item" or a "living thing", once they unleash their power, they will interfere with the aetheric environment.

When the "Prayer Candle" appeared, he had roughly determined its location by observing the clouds of the ether.

That's a manifestation.

There was a similar situation in the just-concluded "Haizhou Incident".

In other words, there are traces of such events, and theoretically, as long as the entire sandbox environment is monitored in real time, then if there is a "spiritual invasion", it can be warned in advance.

Well, in Lin Tuo's thinking, it is similar to earthquake prediction......

The derivation sand table itself should have a similar function, but I don't know if it was because he didn't master it enough, or for other reasons, it was never opened.

And he himself observed with the naked eye, but it was too rough, not accurate enough, and slow to react.

A few days ago, when he found the design diagram of this instrument from the data classics, Lin Tuo was a little excited, thinking about whether he could use it to monitor the sand table.

But after trying it, he found that it wasn't that easy to make.

It's too complicated!

He couldn't even finish the pattern sketching in his consciousness!

At that time, he guessed that it might be his lack of mental strength, or lack of sufficient control skills, so he had to give up temporarily.

Some other complex spell models also have this problem.

This is also the reason why he can only cast low-grade spells at the moment.

If you want to learn it, you must either be familiar with the technique through years of practice, or you are gifted, such as a wizard with certain mental abilities.

However, after entering the "inhuman realm", Lin Tuo's mental strength increased, which made him feel that he could challenge the complex again.

The first thing that comes to mind is the "Magic Distribution Sensor".

"It's not clear if it's effective, but it's better than waiting for a disaster to break out on a large scale and then become a firefighter." Lin Tuo flattened the sterling silver in his hand and muttered.

In the past few cases, except for the "prayer candle", because it involves "rules", it touched the security system of the sandbox and gave early warning.

The other times, it was Lin Tuocai who realized it later...... Just like this time, if he hadn't ended his promotion in time, if it was a little later, I'm afraid things would be irreparable.

So, if you can know about it before it breaks out, or at the beginning of the outbreak, then you have to deal with it much more easily.

Therefore, whether it is useful or not, make it first and try it out.

……

The sterling silver is soft and easy to handle, and Lin Tuo, who has made up his mind, immediately got busy.

There are four major steps in the production:

The first step is to cut the metal into the specified shape according to the design drawing.

The second step is to polish the details of each part and match it.

In the third step, a carving knife is used to draw a complex "pattern" on the surface of the silver plate...... assembled, and injected into the blood medium.

The fourth step is to visualize and outline in your mind, resonate, and activate the instrument.

The structure of the instrument itself is very simple, and the difficulty lies in the last two steps.

The former needs to be careful enough, and if a detail is wrong, it will have to be reversed and reinvented, and Lin Tuo repeated the drawing three times before succeeding.

When the assembly was finally completed, Lin Tuo let out a sigh of relief, wiped his sweat, and thought to himself that this was much more tiring than fighting...... When I looked up, it was dark outside the window.

It took an afternoon.

After stretching and continuing to be busy, the assembly steps were much simpler, and soon, an instrument about the size of a shoebox was assembled.

The instrument as a whole is composed of three parts.

At the bottom is a ring, which serves as a base with grooves.

The main body resembles a checkerboard, made of sterling silver, the surface is painted with patterns, and separated by thin squares, the base is not physically connected to the main body, and when activated, it will be supported by "levitation".

The last part is a round, patterned metal ball, the size of a marble, placed on the surface of the "checkerboard".

The three parts are stacked on top of each other, and under the light, they shine.

"Phew, it's finally done, and the next step is the crucial step." Lin Tuo let out a breath and went to the courtyard with a cup to scoop up a cup of blood in the water tank.

With the addition of anticoagulants, and the special blood of the demonic beast, it has not yet coagulated, and when Lin Tuo filled a large cup, he returned to the study and poured it through the groove of the base, even if it was ready.

Putting down the cup, Lin Tuo calmed down, held down the instrument with one hand, and began to sketch the incomparably complex pattern in his mind.

This is not easy, Rao is mental strength has increased greatly, and it has wasted a lot of energy.

When the Dao pattern in his mind was finally described, Lin Tuo only felt a roar in the mental space, and wisps of ether poured into the instrument from the palm of his hand, and the red blood boiled.

In the next second, a cloud of crimson light suddenly rose from the cold instrument.

Lin Tuo raised his hand, opened his eyes, and saw the aura of the Dao Dao swinging open, and the "chessboard" suddenly trembled and rose, suspended above the pedestal, and the silver bead also dripped.

"It worked!" Lin Tuo was overjoyed, and a huge sense of accomplishment rose in his heart.

Without any further delay, he immediately carefully picked up the thing that he named the "Arillary Earth Motion Instrument" and placed it at the edge of the derivative sand table, in the corner between the light mask and the "isolation cover".

This is where the "Transit Place" was once located.

As for why it is called "Turbulent Earth Motion Instrument"...... Don't ask, asking is a tribute to the ancients!

"Start testing!"

After the placement was completed, the instrument suddenly opened a halo that was almost invisible to the naked eye, enveloping the surrounding area of several meters.

About 100,000 square kilometers of land in Yangcheng and surrounding cities are included in the monitoring scope!

The surface of the "chessboard" glowed, and after a moment it regained calm.

Lin Tuo picked up the design drawing, observed it for a while, and said with relief: "This is the overall stable and no abnormal result." ”

Not bad.

Lin Tuo's heart moved, and he switched it to the "Oasis", and his aura was ...... again Still normal.

Entering the creative mode and selecting "Sandbox Three", this time the light of the instrument has changed slightly, and the suspended plate has a slight tilt.

The silver beads above also rolled in an easterly direction, and then slowly reversed.

Lin Tuo checked the magic book in his hand and nodded:

"It shows that due east is fluctuating in the ether, showing a trough climbing...... Well, Haizhou's vitality is seriously injured and is recovering quickly under the acceleration of time...... Tsk, this machine is pretty accurate. ”

Smiling, Lin Tuo was like a child who had just gotten a toy, thought about it, and then switched the sand table to the No. 2 sandbox.

"Well, the time of the second sandbox has been synchronized with reality, and it is in the Great Ice Age, so it should be the result of overall stability." Lin Tuo analyzed and turned on the test.

In the next second, the invisible aura swayed, and a burst of streamers flickered on the surface of the "Armillary Earth Dynamic Instrument", scurrying everywhere, as if it had been hit by the marquee of the virus......

Above, the small silver bead was even more slippery and swaying around the crooked "chessboard" for a while, circling in a circle, almost irregular.

Next to him, the expression on Lin Tuo's face froze for a while, he looked at the instrument, and then looked down at the book in his hand...... Somewhat dazed:

"What is the result? I don't think the book says it. ”

"Could it be...... Broken? ”

Lin Tuo's eyes were full of doubt, he restarted it once, and the result was still the same result, after thinking about it, he switched to other world experiments, and everything was normal.

There was a brief silence in the room.

"Smack." Lin Tuo closed the magic book, and the expression on his face finally became serious:

"The machine didn't break...... So...... Sandbox No. 2...... Questions?! ”
