Jiang Xilin used the ice shield technique to seal the silver-white box.

After all, there is currently no arcane element input device, so it cannot be studied for the time being.

But that huge finger can be studied.

But the premise is to ensure its safety first.

In fact, it is not difficult to determine the safety. You only need to find some living animals, put them in the same closed space as the cast iron box containing the fingers, and then observe the state of the living animals.

Therefore, after formulating a safety testing plan, Jiangxi Lin began to take action.

Living animals are not difficult to find, and some animals with excellent reproductive capabilities and tenacious vitality are still living well even in this world where the average temperature is minus 17 or 18 degrees Celsius.

The gray-haired rat is one of them.

This kind of mouse has very long gray hair and is only about the size of an adult's thumb. It likes to dig holes in the ground where heating pipes are buried.

Some of them suffer from pinkeye and are also used as materials for certain arcane spells.

Of course, Jiangxi Lin does not need materials, so there is no need to go through the trouble of selecting individuals with pinkeye.

Wearing a coat to keep out the cold, he easily found a nest under the heating pipes buried in the backyard of the institute.

It didn't take much effort to take out the nest of gray-haired rats and put them in the iron bucket prepared in advance.

More than a dozen gray-haired rats were huddled in a pile shivering because the temperature was too low.

Jiangxi Lin did not delay and took them directly back to the warm laboratory.

"Zhizhizhi..."

The warm environment instantly makes these little things come alive.

They fled in all directions at the bottom of the barrel, but this was destined to be a futile effort.

Jiangxi Lin continued to use the ice shield technique to create a huge hemispherical transparent cover.

In fact, it is best to use glass, because using ice will make the temperature inside the cover too low, which will reduce the mobility of the gray furry mouse.

But at the moment he couldn't find a glass cover big enough!

Jiang Xilin controlled the surface of the ice cover and opened a small hole. Then, wearing gloves, he randomly caught three gray-haired rats from the bucket, sent them in, and sealed the entrance of the hole.

Because they were separated from the group and entered a new environment, the gray-furred rats were very uneasy and ran away wildly in the ice cover, even hitting the ice cover many times.

Jiang Xilin used his mental power to control the seal of the cast iron box in the ice cover to melt.

Then the two-hour non-stop observation of the gray-haired rats began.

He watched the gray rats fleeing in panic at first, then hiding in all directions, and now lying on the ground listlessly.

Bang bang bang.

Jiang Xilin knocked on the ice cover, and the gray-haired rats lying on the ground looked at him with eyes slightly larger than black sesame seeds, unmoved.

"The experimental subject is not as lively as when it was first put in, but the cause of this situation is probably related to the temperature inside the ice cover."

Jiangxi Lin wrote down the conclusion on the manuscript paper with a dip pen, and caught a gray-haired rat from the bucket and sent it in for verification.

It was pretty much what he guessed.

After the new gray-haired rats were sent in, the three motionless gray-haired rats immediately regained their vitality.

They ran towards the newly sent gray rat and began to chirp.

He was probably asking the new gray rat how it got in and how it could get out.

Jiang Xilin kept thinking in his mind.

However, through this simple experiment, it was confirmed that the cast iron box enclosing the metal fingers was not filled with any toxic protective gas.

So Jiang Xilin caught the four little mice back into the bucket, and then dispersed the ice cover.

Looking at the metal finger in the box that was thicker than his own thigh, Jiang Xilin, who was wearing gloves on both hands, moved it to the experimental table together with the cast iron box, and then began to study it formally.

The first thing to do is to observe its appearance, color and luster, and make a preliminary judgment on its material.

I won’t go into details about the appearance and color.

In terms of material, Jiangxi Lin couldn't tell what kind of metal it was just by looking at it with the naked eye. After all, he was not a metallurgist in his previous life.

So he found a file and collected some metal powder on his "fingertips", planning to ask Qiu De to go to the alchemy workshop and conduct a composition analysis together with the metal scraps taken from the alloy box.

The second step is to analyze its structure.

Jiang Xilin held the cold fingertips and tested the flexibility of its joints.

It is very flexible, and the structures are interlocking with each other, making it very sophisticated and advanced.

Therefore, there is no problem at all in terms of mechanical structure.

The last thing to solve is how it operates, that is, what energy is used as a driver.

Jiangxi Lin would not be so naive as to think that such an exquisitely constructed mechanical finger was just part of the structure of a certain statue.

According to his understanding, there are currently two mainstream driving methods for mechanical prosthetics on the market in the Kingdom of Tosain.

One is purely steam driven, with complex structure and extremely poor mobility.

The other is driven by steam combined with arcane elements. The structure is still extremely complex, but its flexibility is excellent.

Especially when combined with the spiritual power of a transcendent to assist in the control of arcane elements, it can even produce a power more powerful than the original flesh and blood body.

However, through observation and analysis, Jiang Xilin discovered that the driving method of the finger in front of him was completely different from the known driving method of mechanical limbs.

He first analyzed the components of the mechanical finger and found that each component did not have any settings that could transmit energy.

Then he analyzed other structures, and finally noticed those "silk threads" that were very soft, very thin, but extremely tough.

This kind of silk thread feels very similar to metal wire.

He tried to input some arcane elements and found that unlike other components, it did not seem to exclude arcane elements.

So he began to slowly increase the input of arcane elements.

Suddenly, the metal finger that was lying motionless in the box bent.

And it was this sudden bend that startled Jiang Xilin.

He immediately cut off the input of arcane elements and added three layers of ice to it.

Then I continued to observe it with lingering fear.

It was the same finger, still lying quietly in the cast iron box, without any movement.

Jiang Xilin let out a long sigh and returned his attention to the "threads" he injected with arcane elements, but his brain began to work at high speed.

Obviously, this is just a cold metal creation with no signs of life.

Injecting arcane elements will cause it to react, and it can be determined that it should be driven by arcane elements as energy.

Among the structural components, only "Silk Thread" can receive arcane elements.

Moreover, during the continuous injection of arcane elements, the fingers can react similar to a frog's scratching reflex.

So, these "threads" are the "nerves" of this finger?
