Nine Star Styles, this sword technique is simply a nightmare.
Both those who face it head on in battle, and those who try to learn it.
Peggy only remembered what Ask said at the beginning: "Nine Styles of Stars is a sword art that is highly calculated and changeable."
"Each weapon has its own circle. From the shoulder to the handle is the inner radius, which can draw an inner circle; from the shoulder to the farthest end of the weapon is the outer radius, which can draw an outer circle."
"The line connecting the inner circle and the outer circle is the cutting edge of your weapon."
"What Zhe Rui of the Nine Star Styles has studied is how to use calculations to allow you to avoid or block the enemy's forward line while pressing your forward line onto the enemy's body."
"The inner circle is a circle with a variable inner radius, and its variation comes from the rotation of your shoulder, elbow and wrist."
"Establish a polar coordinate system with yourself as the center. Each joint has three parameters, namely horizontal deflection angle, vertical deflection angle and arm length..."
Peggy couldn't understand what was said afterwards. She only remembered things like "coordinates", "arc length" and "fast calculation". Countless mathematical terms buzzed in her mind, almost making her head explode.
"Well, how do we calculate this inner radius?" Eleanor was also very bad at this, and she poked the ground with a branch in vain. "Do we just add them together?"
Nora looked at her writing and drawing on the ground with curiosity. As a healer, she was not interested in the so-called extraordinary swordsmanship, but academic issues were another matter.
After staring at the geometric figures on the ground for a while, Nora said:
"Assume that the length of the lower arm is x, and the horizontal deflection angle is a; the length of the upper arm is y, and the horizontal deflection angle is b."
"Then, the final inner radius length z is equal to the square root of a square + b square - 2*a*b*cos(180-ab), and the horizontal deflection angle is equal to 90-arcsin(y/z*sin(180-ac))."
Eleanor: ? ? ? ?
"Nora." She said hesitantly and a little ashamed, "Is my brain not fully developed..."
"It's just the law of cosines and the law of sines," Nora said. "You just can't calculate it because you haven't learned it. It's not a problem with your brain."
"Why do I need to know math to learn swordsmanship?" Eleanor burst into tears.
"Ask." Nora turned around and asked Ask, "Your theory... Unless you are a Templar equipped with a computing chip, it is impossible for ordinary people to calculate it in their heads during battle, right?"
"Of course you can't calculate it," Ask replied, "but you can estimate it. Practice makes perfect."

The Galata Bridge in Constantinople fell.
As the other side of the Golden Horn was captured by the Franks, the consequences of the Eastern Solomonic Empire's disadvantage soon became apparent.
Most of the industrial parks were located across the Golden Horn, causing Constantinople to immediately lose most of its arms and ammunition production lines.
In terms of the quality of their soldiers, the Franks were also physically stronger.
Both the Holy Solomon Empire and the West Frankish Kingdom were agricultural countries that had not yet completed initial industrialization. Most of their territories were undeveloped natural wilderness, a paradise for extraordinary creatures to survive and reproduce.
