Two days later in the afternoon, around application time.
Chai Yan found a craftsman in the camp with a drawing. The drawing was a structural diagram of a monocular telescope drawn by Chai Yan himself.
Fan Xingwang has sent people to find the necessary transparent crystal for Chai Yan in the past two days. Chai Yan also found the lens tube needed for the monocular telescope in the bamboo forest. Now he only needs to polish the crystal into round eyepieces and objective lenses, and then
Inlaid on both ends of the bamboo tube, and finally finding a way to connect them to make them retractable, an ordinary monocular telescope is completed.
"Master, I have drawn the drawing for you, and you will polish it according to the pattern in a while..."
As he spoke, Chai Yan spread out the drawings, pointed to the paintings on the drawings and explained: "Master, look, this kind of protruding lens is called a convex lens, and it is used as an eyepiece. What is an eyepiece? It is placed in front of the eyes to see."
This end is called the eyepiece..."
"The other end is called the objective lens, which is the end that sees things. It has to be polished into a concave lens. You see, this lens is concave. You must pay attention to the size when polishing it, and don't turn it upside down."
While explaining, Chai Yan did not forget to pay attention to the details. After all, transparent crystals are not easy to find and cannot be broken casually.
"Don't worry, Taoist priest, your drawings are so clear, no one can make mistakes." The craftsman is a master craftsman and is very confident in his craftsmanship.
Chai Yan said happily: "Then I'll leave it to you, master."
After saying that, the craftsman took the drawings and went back to the barracks to work.
Chai Yan was in a good mood at this time, and he was vaguely excited at the thought of seeing the finished telescope soon.
Just when Chai Yan was about to return to the camp, a trumpet sound suddenly came from the pass defense city, and two streams of beacon smoke rose from the east and west ends of the defense city.
The moment the horns sounded and the beacon smoke appeared, the atmosphere in the camp changed instantly.
Everyone who saw it quickened their pace and speed. Some ran towards their tents, and some shouted loudly: "It's the Pitz people! The Pitz people are attacking!"
Suddenly, the military camp became noisy and noisy, and Chai Yan was surrounded by soldiers running back and forth.
Without thinking, Chai Yan hurriedly ran towards the pass, and happened to meet Jimo Qiao, Cheng Jiu and Yu Tie on the way. Yu Tie also carried Chai Yan's big gourd.
The four people quickly gathered together. Cheng Jiu looked nervous and serious, frowning and said: "Sir, it seems that people from Pitz are coming."
"Yeah!" Chai Yan nodded.
Jimo Qiao couldn't wait to say: "Brother-in-law, let's go to the pass and have a look."
Chai Yan also thought so, and immediately nodded and said: "Okay, let's go up and have a look."
After saying that, the four of them joined the flow of soldiers ascending the pass to defend the city, and quickly moved upward.
As soon as he boarded the Pass Fangcheng, Chai Yan saw Pang Zhenbei who was commanding and dispatching.
At this time, Pang Zhenbei was wearing armor and had a sword on his waist. He was waving his hands continuously and commanding with a strong aura: "Quick! Quick! Hurry up and get to your position!
"
Soon, the soldiers who had climbed up the pass to defend the city were standing at each crenel, with everyone's eyes fixed on the distance to the north outside the pass.
"General Pang." Chai Yan called.
Pang Zhenbei immediately turned to look at Chai Yan: "Taoist Master, you are here."
Chai Yan immediately nodded to Pang Zhenbei, then walked straight to a crenel beside him and looked into the distance.
Pang Zhenbei walked to Chai Yan, looked into the distance together, and said in a deep voice: "These Pitz national dogs can come very quickly."
Chai Yan saw in front of a forest in the distance, countless Pitz soldiers were running and gathering. From a distance, it looked like a densely packed area, and the number of people was extremely large.
While gathering, battle flags of various colors kept moving in front, back, left, and right of the military formation. From time to time, powerful roars would erupt from the military formation, which was so powerful that it shocked people's hearts.
"This day has finally come..." Chai Yan said to himself.
Jimo Qiao stood by the crenel next door, looking at the Pitz army that was constantly gathering. He secretly took a breath of cold air and said in surprise: "Oh my god, how many people are there here?"
After hearing this, Pang Zhenbei replied: "The specifics are not clear yet, but what is certain is that the number of troops is at least double that of last time."
"Twice as much...isn't that 40,000?" Jimo Qiao said in surprise.
Pang Zhenbei nodded and added: "Maybe more."
Cheng Jiu and Yu Tie, who were next to them, saw the Pitz army. Instead of being afraid, they gritted their teeth with excitement and started gearing up.
When Cheng Jiu thought that his country and his relatives and friends had died at the hands of the Pitz people, the anger in his heart couldn't help but rush up: "Damn Pitz country dogs, I have waited long enough for this day.
!”
Yu Tie's face was also quite angry. Although he didn't make a sound, the veins on his forehead and arms had visibly bulged, and his eyes seemed to be spitting out fire.
Chai Yan watched for a while the process of the Pitz people gathering their military formation, and couldn't help but said: "Military discipline is strict and cannot be underestimated!"
Jimo Qiao was not convinced and said loudly: "It doesn't matter whether they have strict military discipline or not, when the time comes, we must make sure these people never come back."
These words sounded very encouraging to Pang Zhenbei, and he immediately responded: "Miss Mo Yu is right, we must make sure these bastards never come back!"
After a pause, Chai Yan asked: "General Pang, why don't you see General Fan?"
Pang Zhenbei immediately pointed to the middle of the city defense and said: "General Fan is over there."
"I'm going to find General Fan."
Chai Yan nodded and walked towards the center of the city. Seeing this, Jimo Qiao and the other three hurriedly followed.
About in the middle of the city, Chai Yan and the others saw Fan Xingwang, who was wearing a silver-white general's armor. At this time, he was looking attentively at the Pitz Army formation to the north, paying attention to every move of those people.
"General Fan!" Chai Yan called loudly.
Fan Xingwang turned his head when he heard the sound, then strode over to greet him: "Taoist Priest!"
After the two came together, they immediately came to a crenel and jointly observed the movements of the Pitz people in the distance.
Fan Xingwang looked into the distance with a stern look on his face and said, "Taoist Master, as expected, the Piz people came with a fierce force this time, and their strength far exceeded the last time!"
Chai Yan nodded, looked into the distance and said, "General Fan, looking at their formation like this, are they going to launch an attack soon?"
"No!" Fan Xingwang shook his head, then said in a deep tone, "This is a deterrent!"
After saying that, Fan Xingwang continued: "The Taoist Master may not know that this is a common trick used by the people of Pitz. Every time they want to attack a city or a pass, they will deliberately build such a big battle, gathering outside to create a big battle.
The purpose of their momentum is to show that they have strong strength, to deter their opponents, and to shake and damage our morale."
Chai Yan twitched the corner of his mouth and said, "It turns out it's trying to attack your heart."
Fan Xingwang nodded and said: "Yes, Taoist priest used the word 'attack the heart' too accurately! However, this little trick only works on those timid people who are cowardly and timid. It has no effect on our Moon God Army.
It's useless. If you don't believe it, Taoist Master, please look around..."
With that said, Fan Xingwang stretched out his hand to signal Chai Yan and the others to look at the surrounding soldiers.
Chai Yan and the others turned around and saw that it was exactly what Fan Xingwang said. Although the soldiers were all ready for battle, there was no trace of fear or cowardice on their faces or in their eyes.
"As expected of the Moon God Army!" Chai Yan said sincerely.
Jimo Qiao was also inspired by this and praised: "General Fan, it is said that a strong general has no weak soldiers. Your soldiers are really good!"
Normally, Fan Xingwang might have said a few words of humility, but at this time, Fan Xingwang happily accepted it with his head held high.
After a moment, Chai Yan's eyes were fixed on a huge dark red battle flag in the distance.
There was a word on the battle flag that Chai Yan didn't recognize. He thought it must be Pitz Mandarin.
"General Fan, is that their military flag?" Chai Yan asked, pointing to the battle flag.
Fan Xingwang looked at it carefully, then nodded and said: "Yes, that is their coach's battle flag."
Chai Yan asked casually: "General Fan, does he know who the enemy's coach is?"
Fan Xingwang glanced at the huge dark red handsome flag again and said: "If I don't admit my mistake, it should be Heng Saar!"
Chai Yan nodded secretly, thinking it was indeed you, Heng Saer, we finally met again!
