After the 'test subject' was in place, some time passed, and the witch doctors of the instrument team began to build all the relevant equipment, including the microscope.

In the process of summarizing and inducing, they obtained the influencing factors of various parameters and succeeded in creating a series of suitable 'lenses'.

Among them, the most extreme data is 25x for the eyepiece and 100x for the objective lens, and the total magnification factor can reach 2500.

Later, witch doctors also tried to make lenses with coefficients of 2600, 2700, and 2800;

But no matter how sophisticated their methods were, and no matter how hard they tried to maintain clarity in the manufacture of lenses, the results were of no avail.

Because once the magnification factor exceeds 2500, the troll's eyes can't see anything.

From this, they came to the conclusion that this was the limit of the 'ice crystal microscope'.

After getting this conclusion, Bladefang also trusted the judgment made by the witch doctors, after all, 'can you see it' is a fairly objective thing....

However, out of curiosity, he eventually went to verify it himself.

But when he tested it with his own eyes, the results he got were quite surprising.....

In order to ensure the temperature of the experiment, the 'microscope room' was placed in a new strange refrigerator tree with a trunk diameter of twenty meters but a height of only ten meters.

The light source inside is provided by sunlight during the day and by huge torches at night;

These external light sources shine into the trunk of the tree through a hole in the top of the tree, and then through a large transparent ice wall.

After that, the mirrors in different positions in the "room" were repeatedly refracted and magnified to illuminate the whole room.

Many mirrors are placed on the edges of the points, depicted with fine scale lines, the refractive points can be manually adjusted when necessary, and the lighting position can be further concentrated in a certain or several fixed positions depending on the situation.

'Inside', in front of the microscope, the blade teeth had finished observing, and asked with some uncertainty,

"Barikun Witch Doctor, are you sure this is a double mirror of 2600 times?"

The 'naturalized witch doctor' Balikun, who had just loaded the 'ice crystal slide', at this time wore the stearin gloves that play a role in heat insulation, and gave an affirmative answer,

"That's right, Your Excellency, this is indeed a 2600x lens.... What's wrong? ”

"But I can still see ....." Blade Fang looked down again, looking at the eyepiece again as if in confirmation, a little puzzled by the fairly clear image in his eyes.

"Impossible, I'll do it myself...."As soon as the negative words were halfway uttered, Barikun hurriedly braked and picked up the explanation,

"I'm sorry.... I didn't mean to offend you...."

These 'naturalized witch doctors' are generally a little unable to let go in front of the blade teeth, and they are always more cautious than the 'original witch doctors'.

Usually Blade Tooth will persuade a few words, but at this moment his attention is completely out of this point.....

He stepped out of the way and said

"See for yourself?"

"Well... Good. ”

Balikun stepped forward as he said and cautiously approached the eyepiece, but there was nothing in his eyes....

After several attempts by the trolls, and then repeated confirmation by the other witch doctors, it was determined that the 'Lenses' were indeed 2600, and all the witch doctors except Bladefang could not see any display.

So, the conclusion is obvious, what is not normal is the eyes of the bladed teeth.....

He couldn't figure out why, so he told Barikun to put on the '2700' lenses and try again.

This time, the result was normal, and the blade teeth couldn't see anything.

'What's going on?' Wait, let me think about it first..... Microscope... Light Microscope... Visible light? “

'Is it the wavelength of the spectrum .' Wave frequency? Which one of them determines the visible range? ..... Is it because my eyes have a wider range of spectral reception than theirs? “

There is no answer to this question for the time being, but it is the only possibility that Bladetooth can think of. And the 'culprit' that caused this result, Blade Fang also guessed - it should be the 'energy level' aspect that is influencing.

However, this was not the time to explore the principle, so he took it to heart for the time being, and said to Barikun,

"The problem should be mine, but it's a good thing."

"Whew... Yes, yes, that's a good thing. Barikun breathed a sigh of relief, and quickly nodded in agreement.

"So.... Leave me a microscope with a 2600" lens set, and then concentrate on the 2500" class. ”

"Understood! We guarantee that we will complete the task with the fastest speed and the best yield! ”

"You... Okay, come on. Blade Tooth patted Barikun on the shoulder, nodded, and turned to leave.

Open and close the 'insulated door' all the way, then pass through the 'preparation room', and finally open the door again before really leaving the 'refrigerator microscope room'.

The reason for the complexity of the design of the leaving process is that the "ice crystal lens" is really sensitive to temperature, and the slightest obvious temperature fluctuation in the storage location will affect its clarity and thus interfere with the light transmission ability.

Therefore, the method of separation of the inner and outer doors is used to keep the temperature of the 'microchamber' constant.

It was late at night outside the 'microscopic room', and in the darkness, only the torches planted by the tribe would provide the only light in the night;

As a result, at night, the tribe becomes extremely dark.

But today it was different, a huge fireball burned some distance away from the top of the refrigerator tree.

Around it, a circle of passages was erected with fireproof wood, and the trolls carried baskets full of charcoal to the ground through a 'viaduct' that connected diagonally downwards to the passage above the fire.

There, the waiting trolls will shovel charcoal into the 'fireball' feed port from a distance away to ensure that it continues to burn.

The work would continue almost all night, until the next morning, when the rising sun took over the task of acting as a light source, and their work was temporarily over.

After admiring the burning fireballs and the trolls toiling for a moment, Bladefang took a deep breath of the wet, slightly dry air that was different from his previous eyes, and finally exhaled slowly.....

"There are so many witch doctors, it's so convenient to do anything.... The microscope matter is over, and the rest is a matter of mass manufacturing, and with the joint efforts of several witch doctors, it should be completed smoothly soon. “

After secretly praising the treaty he had made four years earlier, he went to the Cell Research Institute not far away.

At this time, it was about 12 o'clock in the night, and it was exactly midnight at midnight, but the tribe's witch doctors were still busy diligently.

As for the reason, it can only be said that this is a new working time set for the purpose of accommodating certain 'chief engineers' who are hardly capable of any work during the day.
