"Crack."

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

The scorched earth of Haeju was covered with heavy snow, then thawed and became full of life again.

According to past experience, if nothing unexpected happens, there will be no problems for at least "hundreds of years". However, to prepare for a rainy day, Lin Tuo felt that he still had to find a way.

Make preparations for the next possible "spiritual invasion".

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

On the other hand, as long as the impact of the disaster can be controlled, this may not be a "good thing".

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

It can be judged that if I want to continue evolving, I will definitely have more interactions with the forces of the spiritual world in the future... Invasion of the spiritual world may also help me deepen my understanding of the mysterious realm."

While thinking, Lin Tuo raised his hand, and the "spiritual origin" he obtained after killing the "Head of Haizhou Sect" appeared in his palm...

According to the system prompts, it is still in an "unstable state" and cannot be parsed.

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

"I don't know if it can be absorbed..."

In the dark, Lin Tuo opened the drawer and put it in, preparing to observe it after it was truly "stable".

At the same time, he took out a "silver bracelet" that he bought online a few days ago from the drawer, deftly removed a section of it, put it in the palm of his hand, and came to the sand table.

Switch to "observation mode", and carefully drag one link of the bracelet with the clone and put it into Lishan.

After a while, a slightly low roar was heard at the front door of the martial arts hall. Lin Tuo's dark eyes lit up again, he withdrew his clone and pushed the door open.

After passing through the martial arts arena and arriving at the front door, I saw a huge silver lump several meters high lying on the ground.

If I remember correctly, this was the first time he used the magnification rules of the sand table to perform such an operation on Mount Li.

He squeezed it with his hands and found that it was very soft and of good purity. Lin Tuo had a satisfied smile on his face.

Then he dragged the silver piece into the courtyard, tore off a piece and returned to the study.

"Now the materials are complete."

After letting out a gentle breath, Lin Tuo's eyes became serious.

With blood as the medium and pure silver as the substrate, you can start making it next.

Yes, Lin Tuo is going to make something. To be precise, it is an "instrument"... According to the name in the spell book, the full name is "Magic Distribution Sensor".

It was originally an instrument used by mages and scholars for research in World No. 2. It can be understood as experimental equipment... Its function is also very simple:

Can detect disturbances in the magic environment within a certain range.

Based on his previous experiences, Lin Tuo discovered that the "invasion of the spiritual world" was not traceable.

Whether they are "items" or "creatures", once they release their power, they will interfere with the etheric environment.

When the "praying candle" first appeared, he roughly judged its location by observing the ether cloud.

This is a manifestation.

The just-concluded "Haizhou Incident" had a similar situation.

In other words, there are traces of such events. In theory, as long as the entire sandbox environment is monitored in real time, early warning can be given if a "spiritual invasion" occurs.

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

The Evolution Sandbox itself should have a similar function, but I don't know if it's because he didn't master it enough or for some other reason, but he never turned it on.

However, his own observation with naked eyes was too rough, not accurate enough, and slow to respond.

When Lin Tuo discovered the design drawings of this instrument from documents and books a few days ago, he was a little excited and wondered if he could use it to monitor the sand table.

But after trying it, he found that it was not that easy to make.

Too complicated!

He couldn't even complete the outline of the pattern in his consciousness!

At that time, he guessed that it might be because he lacked mental strength or lacked 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-level spells at present.

If you want to learn it, you must either be familiar with the techniques through years of practice, or you must be gifted, such as a wizard with certain spiritual powers.

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

The first thing that comes to mind is the "magic distribution sensor".

"Although I don't know whether it is effective, it is better than waiting for a large-scale disaster to break out before becoming a firefighter." Lin Tuo muttered, flattening the pure silver in his hand.

In the past few cases, except for "Prayer Candle", which involved "rules", it violated the security system of the sandbox and issued an early warning.

The other times, Lin Tuo only realized what happened after the fact... Just like this time, if he hadn't ended the promotion in time, if it had been later, I'm afraid things would have been irreversible.

Therefore, if we can learn about the incident before it breaks out, or in other words, at the beginning of the outbreak, we will be able to handle it much more calmly.

Therefore, regardless of whether it is useful or not, just make it and try it first.

…

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

There are four major steps in 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 component and match them.

The third step is to use a carving knife to draw complex "dao patterns" on the surface of the silver plate... assemble it and inject the blood medium.

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

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

The former requires a lot of care. If a detail is wrong, you have to start over from scratch. Lin Tuo drew it three times before he succeeded.

When the assembly was finally completed, Lin Tuo let out a long breath and wiped his sweat, thinking that this was much more tiring than fighting... He looked up and saw that the window was darkened.

It took a whole afternoon.

I stretched and continued busy. The assembly steps became much simpler. Soon, an instrument about the size of a shoe box was assembled.

The instrument as a whole consists of three parts.

The bottom is a ring that serves as the base and has grooves on it.

The main body is similar to a chessboard, made of sterling silver, with lines painted all over the surface and separated by fine squares. There is no physical connection between the base and the main body. After activation, it will be supported by a "suspended" method.

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

The three parts are stacked together and glow under the light.

"Huh, we finally got it done. The next step is the crucial step." Lin Tuo exhaled and took a cup to the water tank in the yard to scoop a cup of blood back.

Anticoagulant was added, and the blood of Warcraft was special and had not yet solidified. When Lin Tuo filled a large cup, returned to the study and poured it through the groove of the base, he was ready.

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

This is not easy, even though the mental strength is greatly increased, it also wastes a lot of energy.

When the Dao pattern in his mind was finally drawn, Lin Tuo felt a roar in his mental space, wisps of ether pouring into the instrument from his palm, and his red blood boiling.

The next second, a crimson light suddenly appeared from the cold instrument.

Lin Tuo raised his hand and opened his eyes, and saw a halo of light swinging away, the "chessboard" suddenly trembled and rose, suspended in the sky above the base, and the silver bead also started to rotate.

"Successful!" Lin Tuo was delighted, feeling a huge sense of accomplishment in his heart.

Without further delay, he immediately carefully picked up the thing he named the "Armillary Earth Seismograph" and placed it on the edge of the evolution sand table, in the corner between the light mask and the "isolation mask".

That is where the "Transit Place" once stood.

As for why it is called the "Huntian Earthquake Instrument"...don't ask, just asking is to pay homage to the ancients!

"Start testing!"

After the installation was completed, the instrument suddenly emitted a halo of light that was almost invisible to the naked eye, covering the surrounding area for 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 with light, then returned to calm after a while.

Lin Tuo picked up the design drawing, compared it and observed it for a while, and said happily: "This is an overall stable result with no abnormality."

good.

With a thought in his mind, Lin Tuo switched it to "Oasis", and the aura swayed again... still normal.

Enter the creative mode and select "Sandbox No. 3". This time the light of the instrument has changed slightly, and the suspended plate has a slight tilt.

The silver beads above also rolled toward the east, and then slowly retreated.
To be continued...
