Chapter 718: Mathematics Beginner's Handbook
The night is silent, the rain leaves no trace, and the dark clouds remain on the horizon. This rain is merely a prelude to the overture; the real downpour is already on its way from the west.
On the third day after the fall of White Snake City, Xiulote received more detailed reports. He sat cross-legged in the large tent, carefully reading the numbers in the reports, and his expression changed.
"White Snake City originally had fifteen thousand people. The siege lasted more than a year, and by the time the city-state fell, two thousand two hundred people were captured. Among them, two hundred were captured Cloud Serpent Divine Descendants, and two thousand were surrendering White Snake Samurai, with no commoners surviving. The remaining thirteen thousand either died from disease, slaughter, or cannibalism... A mass grave was discovered at a small temple in the city, estimated to hold the bones of eight thousand people..."
Xiulote lowered his gaze, gently tapping his fingers on the table as if playing a melody. After a moment, he sighed and wrote down a Royal Decree.
"Royal Decree: Demolish the large and small temples in White Snake City and build the temple for the Chief Divine. Dispatch accompanying priests to perform soul-guiding funerals and divine blessing rituals."
"Royal Decree: Send envoys to report the victory to the Alliance; White Snake Hill City has fallen in early July, while Cloud Serpent Mountain City needs to wait a bit longer... Dispatch two hundred Samurai to escort the captured two hundred Cloud Serpent Divine Descendants to the Lake Capital City, for the King and High Priesthood to deal with!"
Then, Xiulote paused a moment, contemplating the arrangement of the two thousand Defectors. This group of Telascallan Defectors had resorted to cannibalism for three months, likely having become fearless and fallen into the ranks of the "Beast Army." His initial desire was to "kill them all."
However, from a political and military perspective, the effects of killing captives are not good. Similarly, these two thousand battle-hardened, boundary-breaking surrendering warriors still possess enough combat ability to fight for the Kingdom.
"Royal Decree: Dispatch accompanying War Priests to convert the surrendering White Snake Samurai, giving them an opportunity for soul redemption."
Xiulote wrote coldly.
"During the two-month rain season, they must be made to follow the Chief Divine. After the peak of the rain season, they will be dispatched..."
Writing this, Xiulote paused again for a moment. Such ruthless Defectors, he neither wanted them assigned to the Telascallan Long Snake Legion nor integrated into various armies within the Kingdom. The only suitable destination for them is...
"Dispatch them to the Seaside Lands, under the Black Wolf Toltec's command, as vanguard for the charge!"
With the issuance of two Royal Decrees, Guard Commander Ecatl tidied them slightly, and then trusted aides swiftly departed as envoys. Bertade had already set out southward at dawn, returning to Water Valley City to continue managing the farming affairs of one hundred fifty thousand people.
Xiulote set down the feather pen and looked towards the northern sky. With White Snake Hill City taken, only the most perilous Cloud Serpent Mountain City remains. Such mountainous terrain makes transporting the siege Mortar Cannon challenging; it will have to wait until after the rain season to attempt. As for the battle situation on the Eastern Seaside, no new information has arrived.
"Once the rain season is over, and the autumn harvest is plentiful... If conditions permit, I shall lead the Imperial Guard Legion to personally campaign on the Seaside, directing the attack on Golden Bay City!"
Xiulote stroked his chin, his gaze becoming resolute.
"Heading east to the Seaside, the first task is to ascertain the layout and control of several coastal city-states, properly dealing with the status of each Vastec and Totonac faction. Then, establish the Eastern Shipyard and form a coastal fleet. Finally, arrange for the opening of Eastern trade routes and the management of Cuba... Only when all of these are settled can I return to the Western Kingdom."
Of course, aside from these obvious reasons, there is an unspeakable reason: the feat of conquering the Totonac Allied Forces should best be led by the King personally. This isn't about guarding against Black Wolf, but rather about valuing and protecting him. After all, having achieved great merit, further rewards may be impossible, and if Black Wolf wishes to continue leading troops in the future, a slight suppression now will benefit him greatly.
"Totonac Coast... Maya Lands... Cuba Snake Island..."
Xiulote's thoughts drifted once more, concerning the fleet drifting in the Caribbean Sea.
"Who knows where the exploration fleet led by the old militia and Tomate has reached? When they return, they must not linger too long in East Totonac territory..."
Two days later, heavy rain arrived as scheduled, bringing the Highland operations to a complete halt. With ample time, Xiulote took out a thick book, patiently completing a task long begun.
"To open new fields, stretching widely from east to west for fifteen steps, and longitudinally from south to north for sixteen steps, how many acres are the new fields? The answer is, 15 multiplied by 16 to give 240 square steps, divided by 240 equals 1, thus one acre..."
Xiulote flipped the book's front page, the first topic of the first chapter he wrote. Referencing his memory of "Nine Chapters on the Mathematical Art," this chapter discusses "Rectangular Fields," introducing Arabic numerals and the four operations, calculating the area of plane geometric figures, facilitating the measurement of acres in village fields.
He sequentially transcribed area calculation formulas for rectangles, triangles, trapezoids, circles, sectors, arc shapes, ring shapes... and detailed derivation processes, along with fraction calculation methods, as an introductory chapter for Chief God Priests to learn mathematics.
The second chapter is "Grains," proposing grain calculations, introducing proportional algorithms, and proportional distribution. The third chapter is "Construction," addressing priests' architectural measurement challenges, focusing on volume calculations, including formulas for rectangular prisms, trapezoid shapes, cylindrical shapes, conical shapes, frustum shapes, spherical shapes, extensions of basic geometric formulas, and project task distribution methods.
The fourth chapter covers "Pythagorean," introducing the Pythagorean theorem, focusing on solving various practical problems in life. For instance, the famous "Draw Reed to Shore" from the "Nine Chapters."
"If a square pond with a side one zhang exists, where a newly grown reed rises one chi above the water surface, pulls it to shore, aligning with the shore, ask how deep the water is, how long the reed is?..."
Starting from the fifth chapter, a new name is adopted: "Algebra One." Xiulote begins teaching "single variable linear equations," using examples such as "gain and loss problems," as recalled from primary school math. Chapter six elevates to "Algebra Two," transforming into "systems of two linear equations," with examples like "Chicken and Rabbit in the Same Cage." The seventh chapter, "Algebra Three," introduces "single variable quadratic equations," emphasizing sketching "quadratic function graphs." The eighth algebra chapter proposes "systems of two quadratic equations..."
"Stop! No need for an eighth chapter, seven chapters are enough!"
At this point, Xiulote felt satisfied. Four chapters covering basic geometry and three on elementary algebra roughly encompass primary plus first-year content. As long as the Kingdom's lower-tier priests learn the content of these seven chapters, most daily life production calculation problems will find solutions.
"Indeed, the content of these seven chapters is almost compiled, serving as a systematic mathematics beginner's guide for Alliance priest apprentices, combined with numerous practical problems, laying a solid mathematical foundation. The book's question bank can be further expanded, ensuring apprentices won't worry about lacking practice questions. Given this, I must choose a striking name..."
Xiulote pondered repeatedly, flipping the book back to a blank cover. Then, he thought hard and wrote down ten striking characters.
"Village Priest's Mathematics Introductory Guide... First Edition, by Xiulote..."
