After the monks had finished reading the displays, Guo Kang urged them to hurry up and go to the next place.

After walking out of the cafeteria, I saw a big car parked on the lawn not far away. At the top of the carriage, a bronze "pot" was housed, resting on an adjustable wooden frame.

"That's a mirror, too." Dmitry was acutely aware that this structure seemed to have just been seen.

"Yes, that's a scaled-down version of the 'Giant of Light' just now." Guo Kang nodded.

"Giants of Light?"

"Oh, that's my personal habit, it's called smooth." Guo Kang explained: "The heavenly brother in the chapel is very grandiose and can also shine, so I used to call it 'Giant of Light'. ”

"It's the first time I've heard that, but it's surprisingly appropriate." Dmitry really thought about it: "At least for our order, this title related to 'Holy Light' is quite good. ”

"This reflector...... Is it made of copper? He asked.

"Yes, it's the bronze that Seris used in ancient times." Guo Kang nodded: "This mirror is not big, so just make one directly with a thin copper sheet, which can save those support and rotation structures, which is a lot simpler." ”

Guo Kang also learned after coming here that bronze mirrors also have a variety of materials and processes. As early as the Spring and Autumn Period and the Warring States Period, in the "Examination of the Work Record", different metal proportions were clearly recorded, and different utensils such as bells, mirrors, axe weapons, spear weapons and arrows had different requirements.

Before the Song Dynasty, mirrors followed this recipe with a high tin content, and the mirror surface was actually white. Since the beginning of the Song Dynasty, the process has changed, the tin content has decreased, and the lead content has increased, which is the yellow copper mirror that later generations usually remember.

Guo Kang needed white light here, so he used an older silver-white mirror. After polishing, the reflective ability is also fully sufficient. The only regret is that it is easy to rust, so when you don't use it, you have to remove it, wrap it in a cloth soaked in oil, and wipe it clean and put it on when you use it.

"They just did a test yesterday, and it's already working properly, and they haven't taken it off yet." Guo Kang beckoned, "Let's go and have a look." ”

He shouted a few times to a nearby wooden storehouse, where several monks ran out and helped him push the cart to the door of the storeroom.

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

The leader of the monk nodded, he asked Dmitry and the others to get out of the way, then stood up straight and shouted: "Bright Chariot, the first article of the Initiation Law, check the source force converter!" ”

A monk opened the side panels of the carriage, slipped into it and patted it around, making sure that the gears and coils were not rusty or loose, and drilled out again.

"The first one is done!" He said loudly.

"The second article of the Initiation Law, check the mirror of holy light!" The leader recited aloud again.

The other monk had already climbed to the roof of the car, and when he heard the command, he grabbed the handle behind the bronze mirror, shook it up and down, and after making sure that it was all right, he looked at the mirror again, took out a piece of silk cloth, and wiped it carefully.

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

"The third article of the Initiation Law, check the heart of light!" The chief said in order.

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

"The beginning chapter is complete, and the Great Light chapter is recited!" The leader said loudly, "One of the Bright Chapters, unlock the lock and activate the Source Force Transformer!" ”

One monk pulled out a long rod from the front of the car and stuck it into the iron plate on the side of the car, while the other pulled out the iron latch that held the turntable in place from the car.

Several monks came over, grabbed the long pole, and then bent down together to exert force and began to shake the iron plate. The clatter of gears and the high-speed rotation of coils were heard in the carriage.

"It's been a really methodical process." Dmitry exclaimed, "The monks of your monastery are indeed devout in their practice. ”

At this point, he also understood the next steps.

"Light Chapter 2, connect the lightning pool, activate the magnetic coil group, and monitor the lightning intensity!" The leader continued to chant.

"The advantage of this equipment is that it saves the part of the magnet." Guo Kang explained: "Our magnets are not very magnetic, and they are too heavy. In the giant of light, the shortcomings are not obvious, and it is not suitable to put it in the car. So here, it's started with a battery, and this thing can be disassembled, or just find another car to carry it. ”

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

"It's a meter for measuring current. It's actually an electromagnet inside, and the stronger the current, the greater the force that pulls the pointer. Guo Kang said: "As for the pointer itself, it is actually a ...... Yes, it's a torsion trebuchet. ”

"Oh, so I get it." This explanation was easier for the Romans to understand, and Dmitry understood the meaning at once.

"And how do you determine the scale?" He asked.

"It's not that difficult, just use the coil to pull the weight." Guo Kang said: "For example, if I use 100 circles of copper wire to pull a weight of one tael, then the 'lightning intensity' at this time will be recorded as 1 tael divided by 100 circles. Measure it a few more times and make a scale. ”

As they spoke, the monks shook faster and faster, and soon, the current reached a red line.

"Light Chapter 3, disconnect the pool of lightning and connect the light circuit!" The leader ordered.

A monk walked up to the carriage and lifted a wrench with a drawing of a pool and electricity, and then pressed a wrench with a halo on it.

Once again, the roof emitted a continuous arc light. This time it is much darker than the previous Brother Tian's Lighthouse, and it is not very conspicuous during the day, but with the reflector, it is also impossible to look directly.

"This thing will work well at night." "Actually, I think the cars are too big. It would be nice if it could fit on horseback. ”

"I can keep trying, but the arc light is ...... power It is the size of the input 'source force', which is relatively demanding. We can't do those with low power and high efficiency. So I don't think it's that small. Guo Kang said truthfully.

"And what if it's divided into parts?" Tuohuan asked: "Our small artillery, when it encounters mountainous areas that are difficult to pass, do this. The gun carriage and barrel are disassembled, and then assembled in the place. Can this thing do it? ”

"It's ......" Guo Kang hesitated: "Then I'll try." What do you want? ”

"It's for night raids." "Do you think what effect would be if we attacked the Ottoman camp and then used a few chariots of light, and suddenly turned on the lights in the middle of the night to project a huge Heavenly Brother into their camp?" ”

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

"yes, the Crusaders are a piece of. One of our actions will be ten times the propaganda effect of the Crusaders. Dehuan said proudly.
