What are the bells and whistles, the magic arrays in these folders are called bells and whistles.

Jiang Feng felt like a candidate who had the answer in his hand but didn't know which box to fill in on the paper, because the exam questions were so varied.

Hearing Jiang Feng's answer, Sun Junming replied with some tears and laughter: "It's okay, no one is urging you, just watch it slowly, although I really want you to come over and discuss it in person, but this is a battlefield after all, and it's still a bit dangerous, so if you find anything, just call me by video." ”

"Okay, but I should need more time this time, I think this batch of magic arrays not only changed the basic laws, but even added new elements."

"Of course, I said that no one will rush you, but you only watched it for five hours and you saw the new rules?"

"It's just that feeling, so I need time to be sure."

The reason why Jiang Feng had the feeling of holding the answer in his hand but not knowing how to fill it in was because he saw many structures and runes that he had seen before.

"Well, then you can study it slowly, and call me directly if there is news."

"Okay."

Hanging up the phone, Jiang Feng moved his gaze back to the computer screen and continued to study the hundreds of magic array diagrams.

……

Although Teacher Sun said that no one would rush him, Jiang Feng knew that solving these magic arrays was the biggest problem on the front line, so he asked for leave from several teachers the next day.

In the face of Jiang Feng's leave, several teachers replied directly without even asking the reason, "I know." ”

Maybe it was because he had studied this brand-new concept of magic array for a long time before, this time Jiang Feng was not stumped for too long, and he soon found a new breakthrough point.

"Dut...... Honk...... Hey, can you see that? ”

Answering the video call, Sun Junming leaned in front of the camera and asked.

"You can see, teacher, I think I've found a new element in this magic circle."

"Hahahaha." Sun Junming laughed heartily after hearing this, "A genius is really a genius, let's say, what is it?" ”

"Planetary time."

There was astrology in this world, but most of the time it was used in divination, and very few of them could be used in magic, which had something to do with the fact that shamans were able to observe the universe by [Vision] very early, so that the universe and the stars lost their mystery too early.

And in this series of magic arrays of Yugsaron, Jiang Feng discovered this new element.

"Planetary time?" Sun Junming frowned slightly, thought for a while, and asked, "Have you summed up the rules?" ”

That's right, Jiang Feng nodded and moved the camera to the six large blackboards borrowed behind him.

[Monday represents the moon and is the day of the moon]

[Tuesday represents Mars, the day of fire]

[Wednesday represents Mercury, which is the day of the Lunar New Year]

[Thursday represents Jupiter, which is the day of Muyao]

[Friday represents Venus, which is the day of the Golden Day]

[Saturday represents Saturn, which is the day of the earth]

[Sunday represents the sun, which is the sun]

"This is the most basic knowledge in astrology, the time of the planets is different, the magic tides caused are also different, and the movement between the planets will have a great impact on the earth."

Pulling out the cap of the pen, Jiang Feng used a black oil-based pen to write on the blackboard as he spoke: "I'll take Mercury precession first. ”

Jiang Feng said and drew a schematic diagram with the sun as the center of the circle and point D as the descending node of Mercury's orbit.

"By calculation, if Mercury starts from point D and circles the sun once and returns to point D, the period is 8231437 seconds, while the period of Mercury from point G to circle the sun and return to point G is 8231025 seconds, and the two cycles are not the same, which is orbital precession, which rotates counterclockwise with the sun as the center."

After speaking, Jiang Feng clicked on the computer and opened the No. 7 and No. 18 magic arrays respectively.

"Teacher, you see, the moon maps of these two magic arrays obviously reflect each other, and the messengers and communication runes behind them can also resonate."

Hearing this, Sun Junming showed an expression of sudden realization: "So these two magic arrays are not related in terms of structure and meaning, but if they are calculated by astrology of time, they are a community?" ”

"Yes." Jiang Feng nodded, picked up the oil-based pen and continued to draw the schematic diagram on the blackboard, and listed the formula.

[Let Mercury's period be T, the time for Mercury to move from D2 to D1 is T1, and the time for Mercury to move from G2 to G1 is T1.]

then (T-T1)-(T-T2)=14 seconds, and T2-T1=14 seconds.

Suppose Mercury orbits for one cycle, and the observer rotates (or orbitally precession) at an angle of Ω. The distance between the ascending node of Mercury and the Sun is: 47015159.7 km, the velocity of Mercury at the ascending node is 57.7 km/s, the distance between the descending node of Mercury and the Sun is: 67604398.5 km, and the velocity of Mercury at the descending node is 40.13 km/s:

then Ω*67604398.5/40.13 -Ω*47015159.7/57.7 = 14 seconds.

Gets Ω = 0.0000160944 (radians) per Mercury year. 】

"That is, the precession value of Mercury's orbit per 100 Earth years is 1378.4 arc seconds."

At this point, Sun Junming was already a little dizzy when he heard it, but in order to show the momentum of the teacher, he still kept nodding his head in affirmation.

Seeing Sun Junming nodding, Jiang Feng pulled over a blackboard again, pointed to the table on it and said, "Since the movement of the stars will have an impact on the magic tides, the calculation of the orbital period of Mercury's ascending and falling nodes has become very important. ”

"I made a table of the transit time of Mercury's ascending node, the minimum solar distance and the transit time interval of the next line, the time complement, the complement ratio, the time after Mercury's complement, and the number of Mercury's orbits, so that I could accurately calculate Mercury's average orbital period and then begin to calculate its influence on the Earth."

"Then pass the gravitational constant......"

【(G)= 6.6726*0-11N-m2/kg2】

"Wait a minute."

Seeing that Jiang Feng became more and more energetic the more he spoke, Sun Junming raised his hand and shouted.

Jiang Feng, who was writing the formula, paused his hand and looked back at Teacher Sun in the video.

“emmmm…… You're doing a good job, but I'm a little busy here, and I don't have so much time to listen to you, so you pack all the ideas and materials you sorted out and send them to this mailbox, I'll read them later. ”

"Okay." Jiang Feng nodded, "Then I'll send it to you now." ”

"Well, then I'll go and get busy first, and I'll get back to you when I get back in the evening."

"Okay, goodbye, teacher."

After Jiang Feng finished speaking, he hung up the video call, compressed all the information and ideas he had researched in the past few weeks, and put them in this mailbox.

After clicking [Save], Jiang Feng let out a sigh of relief, took out a pen and continued to start his morning's calculations on the blackboard.

When the verification was over, Jiang Feng looked at the blackboard with an oil-based pen against his chin for a while.

"I don't know if Yugsaron created these magic arrays by calculation, or if it was some other way...... If it is really calculated, to be able to create so many related magic arrays in one go, this Yugsaron is afraid that he is a great mathematician. ”
