Mage? Spell Engineer!

Weak areas of the transmutation dust flow are observed indirectly, and in fact they do not penetrate the entire stratum.

First, the astrologer station on the Star Torch Tower observed that a star had deviated from the determined trajectory, and for the first time a lower-brightness star was discovered around it.

Regarding this phenomenon, some scholars believe that the star has changed, such as splitting, which can explain the above two phenomena. But some people have questioned that the star splitting hypothesis cannot explain why the original star is even brighter.

There are even "archaeologists" who point out that the existence of those stars is recorded in ancient books and ancient star charts.

Only Kano guessed that it might not be a change in the starry sky, but a change in the transmutation laminar flow that he and his research team have been dealing with. Combined with the sixteen extraction machines currently in operation in Valuauna, the fluctuations in their extraction volume and the changes in the starry sky occur almost simultaneously.

In the laboratory, Paulina is assembling a special glass experimental device. The main body is a large transparent water tank with six holes at the bottom.

Master Poincaré was also in the laboratory. Under Carnot's instructions, Paulina drained water on one side of the water tank. The water outlet was also specially made to allow the water to flow from left to right in the water tank in the form of parallel laminar flow. When opening a hole in the middle, some water flows out of it and turbulence occurs.

Carnot cast a spell on the experimental device to deform it, and the hole at the bottom of the cylinder began to move. Under a specific combination, the disturbances generated by the hole interacted with each other, and small turbulence merged to form a larger vortex centered on the largest hole.

"So your experiment is trying to prove" Poincaré pondered for a moment: "The transmutation dust extractor array disturbs the original laminar flow, and the mutual interaction coincidentally produces a larger vortex? Therefore, a relatively large vortex appears near the center of the vortex. The thin area causes changes in the stars observed by the astronomical observatory.”

"Yes, this makes sense, and the thickness at the thinnest point should be significantly smaller than normal. Otherwise, the changes in the stars would not be so significant. There are even lower-brightness objects whose light can penetrate us for the first time. This 'shell'."

"This is not the first time." Poincaré corrected: "News came from Istani's Tower of Time. After comparison, the so-called four newly appeared companion stars are part of the Perseus constellation that disappeared after the 'Great Extinction'. "

"Doesn't that further confirm my point?" Kano hammered the palm of his other hand with one hand: "After the mass extinction of the symbolic world, the transmutation laminar flow interfered with the lower-brightness stars. Now there is a weak area in the laminar flow, allowing some The stars reappear."

The obscuring effect of the transmutation dust stream caused a severe setback to astrology and celestial magic, and it may also be related to the demise of the power entity corresponding to the constellation. In any case, the news from the Tower of Time confirmed Kano's conjecture.

"So the purpose of why you called me here is..." Poincaré had already guessed something, so it was better to confirm with the fat man first to be on the safe side.

Carnot was so excited that he almost trembled: "Help me, Jules Poincaré! Now we have sixteen machines. The coordinates and extraction rates of the transmutation dust they extract are controllable. I want you to calculate an optimal Solution, use these machines in an array to create the largest vortex, creating larger and thinner areas in the laminar flow of transmutation dust!”

"Calculation? You layman!" Unexpectedly, Master Poincaré responded to the Archmage's request with an almost roaring voice. He pointed at the water tank model and said:

"What do you want me to be? A fluid! A chaotic system composed of endless dust. To find a special solution means endless calculations! And how much do we know about transmutation dust? Unprocessed particles scattered in the star world What is their equivalent viscosity coefficient? Or is it in a three-dimensional system? If you can get all the minds in the world to participate in this work, then maybe there will be a day when you can do it."

Carnot was frightened by Poincaré's "roar" and said slowly: "In the past few years, we have measured the flow velocity gradient between the lower and middle layers."

"Ha" Poincaré almost laughed out of anger.

Even so, all the remaining mages and apprentices in the Tower of Stars participated.

The Tower of Stars, which hides its actual location, has become the "eye of the storm" in Valuauna. The apprentice mages who have not joined the army and have taken refuge in the countryside do research behind closed doors and concentrate their efforts on serving the chief archmage's projects.

First of all, we need to obtain more data. Three intermediate mage teachers led a team, took the floating capsule produced by the Alchemy Department to the highest height for safe transmission, and released three sounding balls under the laminar flow of transmutation dust.

The aerostat and the sounding ball are all equipped with the blue barrier disclosed by Rorschach. It is precisely because of the existence of the barrier that can resist the transmutation dust that it is possible to penetrate the transmutation laminar flow.

However, the barrier was only working in the extractor before, and the amount of transmutation dust in the transmission-spray was very different from the amount of transmutation dust in the laminar flow above the sky. This time is also a test of how long the barrier can maintain operation.

"Teacher, ball No. 3 has lost contact, and the trajectory information of the other two balls has been collected."

"Okay, let's return first." The barrier of the floating cabin gradually failed, and the chill from high altitude penetrated the temporary and crude cabin. After collecting the data and concluding the relationship between the thickness of the barrier and the retention time of the laminar flow of transmutation dust, the floating capsule stopped operating the [Levitation Technique] and fell naturally. When it accelerated to a certain speed, the magic circuits around it lit up and disappeared. High in the sky.

By this method, eleven groups of sounding ball movement data in the transmutation laminar flow were collected, and the basic parameters of the lower layer of transmutation dust were initially sketched.

Based on these data, the computational team led by Poincare reported the simplified model of transmutation dust flow for the first time. Their research also attracted the attention of the Tower of Time, which also began to try.

Poincare found an approximate periodic law from the changes in the transmutation dust level and proposed an idea: change the parameters that are small enough for the chaotic system in order to fine-tune the target variables without affecting other variables of the system, and finally achieve the steady state required by Carnot.

In addition, there are many efforts. All computing machines and students are running. The laboratory is full of calculation processes. There are also water models, oil models and quicksand models made to simulate the macroscopic flow of transmutation dust. They flow back and forth under the control of sophisticated alchemical devices.

In the end, they obtained a model that was very rough in Poincare's eyes, which was improved from the "special solution" obtained by chance. According to the calculation results, the parameters of the transmutation dust extractor of the Tower of Stars were adjusted, and the small piece of abnormal starry sky was successfully made a little brighter.

It is that little bit that shows that the work is effective and the weak area of ​​the transmutation dust layer flow can be thinned!

The above is the research that the Starry Tower has been carrying out since the beginning of spring, and it has been going on for four months. However, Rorschach was not aware of it. In addition to the results of the Poincare Group and the sounding surveying group, the content related to Kano's own work has not been published publicly, and Rorschach has not paid attention to it.

When Rorschach's telegram came, it gave Kano further ambition:

"Yes, we forgot the machine that Rorschach can control! If we count the transmutation dust extractor on Rorschach's side and form a larger array, can we get the best effect and let me achieve the crossing?"

"Are you crazy? Are you going to take the risk yourself?" Master Poincare grasped the key point in Kano's words.
