Since the Accounting: A Chronicle of the Roman Khanate

Chapter 149 The Giant of Light Brother Tian
After the monks finished watching these exhibitions, Guo Kang urged them to hurry up and go to the next place.

After walking out of the cafeteria, I saw a large car parked on the lawn not far away.On the top of the carriage, there is a bronze "pot" mounted on an adjustable wooden frame.

"That's also a reflector." Dmitry was keenly aware that this structure seemed to have been seen just now.

"Yes, this is the shrunken version of the 'Giant of Light' just now." Guo Kang nodded.

"The Giant of Light?"

"Oh, this is also my personal habit, it's called fluent." Guo Kang explained: "The heavenly brother in the chapel is very magnificent and can also emit light, so I'm used to calling it the 'Giant of Light'."

"It's the first time I've heard this term, but it's surprisingly appropriate." Dmitry really thought about it carefully: "At least for our congregation, this title related to 'Holy Light' is not bad."

"Is this reflector . . . made of copper?" he asked.

"Yes, it is the bronze commonly used in Seris in ancient times." Guo Kang nodded: "This reflector is not big, so we can just make one with a thin copper sheet, which can save those supporting and rotating structures, which is much simpler."

It was only after Guo Kang came here that he realized that bronze mirrors also come in a variety of materials and techniques.As early as the "Kao Gong Ji" in the Spring and Autumn and Warring States Periods, it clearly recorded different metal ratios, and there were different requirements for different utensils such as bells, mirrors, axes, spears, and arrows. It is indeed very ancient to know the distinction.

Before the Song Dynasty, mirrors continued to use this high tin content formula, and the mirror surface was actually white.Since the Song Dynasty, the craftsmanship has changed, the tin content has decreased, and the lead content has increased. This is the yellow copper mirror that posterity usually thinks of.

Guo Kang needed white light here, so he used an older silver-white mirror.After polishing, the reflective ability is completely sufficient.The only regret is that it is easy to rust, so when not in use, it has to be removed, wrapped in an oil-soaked cloth, and then wiped clean when in use.

"They just did a test yesterday, and it can be used normally, and it hasn't been disassembled yet." Guo Kang greeted: "Let's go and have a look."

He yelled a few times towards a wooden warehouse next to him, and a few monks ran out there to help him push the cart to the door of the warehouse.

"It's darker in this shed, just right." Guo Kang said, and said to the monks: "Let's get started."

The head monk nodded. He let Dmitry and the others get out of the way, then stood up straight, and shouted: "Chariot of light, the first law of the initial law, check the source power converter!"

A monk opened the side panel of the carriage, got inside and patted around, making sure that the gears and coils were not rusted or loose, and then got out again.

"Rule number one done!" he exclaimed.

"The second rule of the starting law, check the mirror of the holy light!" The leader recited loudly again.

Another monk had already climbed to the roof of the car. Hearing the order, he grabbed the handle behind the bronze mirror and shook it up and down. After confirming that there was no problem, he looked at the mirror again, took out a piece of silk cloth, and wiped it carefully.

"The second one is completed." He also said in a deep voice.

"Article [-] of the initial law, check the heart of light!" The leader said step by step.

The monk on the roof changed a piece of sackcloth, wiped the glass tube in front of the mirror, looked at the carbon rod inside, and reported: "The heart of light is normal, the sacred graphite is sufficient, and the third one is completed!"

"The initial chapter is complete, recite the Great Light Chapter!" The leader said loudly: "One of the Bright Chapters, unlock and activate the source power converter!"

A monk pulled out a long rod from the front of the car and inserted it into the iron plate on the side of the car, while the other pulled out the iron pin that fixed the turntable from inside the car.

Several monks came over, held the long poles, and then lowered their backs together to shake the iron pan.Immediately there was the clicking sound of gears in the carriage, and the sound of high-speed rotation of the coil disc.

"This process is really orderly." Dmitry praised: "The monks in your courtyard are really dedicated to practice."

At this point, he also understood the next steps.

"Bright Chapter [-], connect to the pool of lightning, activate the magnetic coil group, and monitor the intensity of lightning!" The leader continued to chant.

"The advantage of this device is that it saves the part of the magnet." Guo Kang explained: "Our magnet is not strong, and it is too heavy. The shortcomings of the giant of light are not obvious, so it is not suitable for the car. So here, it’s battery-started, and this thing can be disassembled, or you can find another car to take it with you.”

While chanting, the leader also came to the front of the car and began to observe a pointer that rotated left and right.

"That is an instrument for measuring current. It is actually an electromagnet inside. The stronger the current, the greater the force pulling the pointer." Guo Kang said: "As for the pointer itself, it is actually a... yes, a torsion trebuchet."

"Oh, so I understand." This explanation is easier for the Romans to understand, and Dmitri really understood the meaning at once.

"So how do you determine the scale?" he asked.

"This is not difficult, just use a coil to pull a heavy object." Guo Kang said: "For example, if I use 100 turns of copper wire to pull a heavy object of one tael, then the 'lightning intensity' at this time is recorded as 1 tael. Take 100 laps. Measure a few more times to make a scale."

While talking, the monks shook faster and faster, and soon, the current reached a red line.

"Bright Chapter [-], disconnect the pool of lightning and connect the circuit of light!" the leader ordered.

A monk walked to the side of the carriage, lifted a wrench with a drawing of a sink and electricity, and then pressed down a wrench with a halo.

The roof once again emitted a continuous arc.This time it is much darker than the previous Tianxiong Lighthouse, and it is not very conspicuous in the daytime, but with the reflector, it is also impossible to look directly at.

"This thing will be very useful at night." Tuo Huan said, "Actually, I think the car is too big. It would be great if it could be mounted on horseback."

"I can continue to try, but arc lamps have relatively high requirements on the power...that is, the size of the input 'source force'. We can't make those with low power and high efficiency. So I don't think it's too small. Go." Guo Kang said truthfully.

"Then how many parts should it be divided into?" Tu Huan asked: "Our small artillery always does this when it encounters mountainous areas that are difficult to pass through. Disassemble the gun mount and barrel, and reassemble it at the place. This thing can Did you do it?"

"Its words..." Guo Kang hesitated: "Then let me try. What do you want to do?"

"For night raids." Tu Huan said naturally, "Do you think, if we attack Ottoman's camp, and then use a few light chariots, suddenly turn on the lights in the middle of the night, and project a giant heavenly brother into their camp, what effect will it have? "

"The legend of the 'Giant of Light' will spread more widely." Brother Demetrius said with certainty.

"That's right, the Crusades are nothing. If we take one action, we will get ten times the propaganda effect of the Crusades." Tuohuan said proudly.
