"What do you mean?" Zhao Danqing caught the citrine coin thrown by Jiang Xingchen and looked at the old man suspiciously.

"Stupid, what can it mean! Let's guess the pros and cons, whoever wins will be named by whomever it is!

"Oh!" Zhao Danqing suddenly realized, nodded and said: "This method is good! Guess it, I'll throw it!"

"Why are you throwing it! I'll let you guess first!" The old man snatched the citrine coin in Zhao Danqing's hand.

"Old thing, you don't come to this set! You have eight layers of vitality, it's too easy to control the citrine coin!" Zhao Danqing smiled and took out another citrine coin from his pocket......

Not long after, Zhao Danqing ran out with a string of smug laughter. The old man behind him shouted angrily: "Don't count, don't count this time, you kid is cheating!"

Jiang Xingchen had just walked not far when he heard a voice behind him and turned around.

"Brother, if I win, let's call it an avalanche cannon!" Hahahaha......" Zhao Danqing couldn't express his excitement when he thought that such a powerful weapon was named by himself.

Jiang Xingchen smiled and patted Zhao Danqing's shoulder: "Awesome! I won the old man, but did I say that I want to use your name?"

"Ah!" Zhao Danqing was stunned: "Brother, don't bring this! You just said that the quarrel was fruitless, and threw a citrine coin out, didn't you let us guess the winners and losers?"

The corners of Jiang Xingchen's mouth twitched, and he said lightly: "You love gambling so much with the old man, giving you a citrine coin to guess the pros and cons, but just letting you have fun!"

As he spoke, Jiang Xingchen waved his hand, turned around and walked forward. "The name is the cannon!"

Zhao Danqing stared at Jiang Xingchen's back and blinked his eyes, with a declining expression. This Nima is too pitiful!

The old man who chased after him heard it really well in the back, and pointed at Zhao Danqing is burst into laughter: "It's time for retribution." Let your kid play tricks!"

"Old thing, you're still laughing, we've both been tricked, okay! He still uses the name of the cannon to the scum!" Zhao Danqing jumped to his feet and shouted.

"Uh! it seems to be!" The old man was stunned, and then he reacted, he and Zhao Danqing were both tricked!

Then the old man jumped to his feet, guessing the pros and cons to decide the name, but he came up with it, how embarrassing.

"This little soul is too annoying! No, chase! We have to use our name, such a powerful weapon. You can't use the same name as a turtle!"

"Wait a minute, you!" Zhao Danqing grabbed the old man and said, "Brother Jiang doesn't agree, let's have no problem!

"What?" the old man twisted his face and asked puzzledly, "What do you mean by giving wild pheasant eggs?"

"Let's have fun!"

"If he doesn't agree to, I'll steal all his wine!" said the old man through gritted teeth.

Zhao Danqing's eyes lit up when he heard this, and he slapped the old man hard: "Good idea! But you can't threaten him, what if he wants to transfer the big bee!"

"Yes, yes, yes!" the old man pulled Zhao Danqing to a darker wall and squatted down, and whispered, "Do you have any good ideas?"

"We might as well be like this. Steal his good wine first, and then threaten him!What do you think?" Zhao Danqing said with a smile.

"It's a solution!" the old man nodded, and said in a low voice: "And the good tea he treasured! In the autumn, he hid another batch and brought it to him! It's so annoying to take a citrine coin and let us play around!"

As he spoke, the old man threw the citrine coin in his hand to the ground angrily.

A gust of wind blew. The snow on the top of the wall fell and fell on the two of them.

At this time. Several tourists approached from the front, and at a glance they saw two people squatting in the corner of the wall with their heads bowed. I couldn't help but be surprised.

"I'll go, Xingchen Ling also has a request for food?"

"It's true, there are poor people in such a rich place as Xingchen Ling!"

"What's new about this, there are rich and poor everywhere...... But the people who ask for food here are better than other places, and they all need citrine coins to ask for money!"

"I'm making it, it's really a citrine coin! So what do they want?"

"Xingchenling has a high level of consumption, and eating and drinking are several times more expensive than elsewhere, and it is impossible for people to live without it!"

"It makes sense, let's give some too! It's not easy to squat outside on this cold day!"

Several people had already arrived in front of them while they were talking, and the leader took out a citrine coin and still walked in front of the old man.

The muscles on Zhao Danqing and the old man's faces twitched for a long time, then they got up suddenly and roared loudly: "You are blind, don't we ask for food!" The eyes of the two were upside down, the top of their heads were on fire, and the green tendons were all over their heads.

"Oh, I'll make it!" Several tourists were startled, only to realize that they had seen it wrong, to say that the old man was still a little similar, wearing a torn robe all the year round, but Zhao Danqing's appearance didn't look like asking for food.

"You are paralyzed! Who made you squat in the dark corner, can we see clearly!" Several people complained in their hearts, and their mouths were not to be outdone. The leader replied loudly: "What are you doing in the corner where you don't want to eat, is there a secret that you can't tell! If you have the ability, don't go, brother! Go to the security team, and say that there are two strange people here!"

"Hey, you're still arrogant when you see the wrong person, aren't you?" Zhao Danqing rolled up his arms and sleeves and was about to walk forward.

The old man grabbed him: "Zhao boy, let's withdraw, if the trouble reaches the ears of Xiao Soul, let's not want to steal from him!"

The old man didn't wait for Zhao Danqing to reply after speaking, and pointed to a few tourists: "Forget it this time, next time you have more eyes!"

"Why don't we have eyes...... the lead tourist was of course not happy, and shouted loudly with his neck stalked. But the old man ignored him, dragged Zhao Danqing and ran away.

"Big brother, amazing!" The rest of the tourists couldn't help laughing when they saw the old man and Zhao Danqing fleeing, and raised their thumbs at the leader.

"That's!" The leader was also very proud: "This is the star leader, everyone has to obey the rules!"

"Big brother, these two people are really strange, what do you say about the security team......? Let's talk to the vigilantes about this!"

"You're full!" The eldest brother glared and said, "We're here to play, if the security team asks you this and that every day, let's still play a fart!"

"Big brother is right! Hehe, we have an extra citrine coin!" a tourist ran over and picked up the two citrine coins on the ground......

At this time, Jiang Xingchen had already arrived in the back mountain, and this time he needed to go to the cursed land to make cannons, and there were many people and things to bring, so he was going to bring more wind wolves. Anyway, now that the train is opened, the number of wolf sleds has decreased, and the wind wolf can also have more than two dozen free.

After letting Leek be in charge of summoning the Wind Wolf, Jiang Xingchen went to the research institute again, and the crab was always there.

As a result, as soon as he arrived at the research institute, he saw Xian Ning hurrying out from the inside, holding something like a cylinder in his hand.

"Xingchen!" Seeing Jiang Xingchen at a glance, Xian Ning stopped and said with a happy face: "I was about to look for you!"

"Seeing that you are so happy, is there any good thing, has the float glass research been successful?" Jiang Xingchen asked.

"Float glass has to wait!I'm looking for you for another matter, you look at this!" Xian Ning said, handing the cylinder in his hand to Jiang Xingchen.

"This is ......" Jiang Xingchen took it and found that it was wooden, thick at one end and thin at the other, with glass sheets installed on both sides!

"It seems to be a telescope!" Jiang Xingchen immediately remembered the kind of monocular in the TV in the previous life.

Xian Ning was stunned for a moment, and said: "Telescope, you know this thing! But the name is really apt, Tong Guò is a thing that can see far away!"

After Jiang Xingchen first made the magnifying glass, he thought about getting the refracting telescope out as well! However, the telescope was not as easy as imagined, and the Galilean observation field was small and the distance was close. Keplerian objective lenses require objective lens groups to eliminate chromatic aberration, and there must be a positive image system in the middle, either with a prism or a lens, and it also takes time to make a solid lens. And he hasn't been idle, he doesn't have time to get it.

"Xianning, did you make this?" Jiang Xingchen fiddled with the monocular twice, and sure enough, he found that the two tubes were put together, which could be stretched out to adjust the focal length.

"It's not me!" Xian Ning shook his head and said, "It's a child with a good academic performance, I just transferred him to the real yàn room not long ago, his name is Zhou Lin, and he is only seventeen years old this year!"

"Oh?" Jiang Xingchen was surprised, a child who had just entered the real room would be able to study a telescope!

"This kid is a big fan of yours and has always looked up to you as a role model. One of the things that came to my lips was that the lord had invented a lot of things when he was sixteen years old!" Xian Ning said with a smile.

"This kid must be focused on cultivating! Tell him, the telescope has a broader research space!" Jiang Xingchen said seriously. Now that Xingchen is leading the development, what is lacking is talent. Although those old craftsmen have good craftsmanship, it is impossible for them to innovate, and they can only lead the problem by themselves. Therefore, it is necessary to constantly discover new geniuses, and he and Xian Ning have always been committed to this.

"I don't need you to say it! Zhou Lin is already a key training object! And Miss Nier, the graphic papyrus she drew is piled up in half of the room! ”

"Is there any progress?" Jiang Xingchen asked, it's been more than half a year since he spoke.

"It seems to be a little progressive!But I don't know the specifics!" Xian Ning shook his head.

"Hmm!" Jiang Xingchen nodded, didn't say anything more, told Sù Xianning that he was going to go out for a while, and then found the crab and walked back.

When leaving, Jiang Xingchen took the telescope with him. He thought that navigation would be indispensable in the future, and he remembered that in the previous life, this kind of monocular was also called a pirate scope.

While walking and researching along the way, Jiang Xingchen found that although the telescope made by Zhou Lin still had many shortcomings, it was already quite good. The chromatic aberration has not been solved, but even the orthographic system is available, and what you can see from the eyepiece is the orthographic image. And the field of vision is wide, and you can see very far away...... And just as he was fiddling with the binoculars, he suddenly saw something interesting. (To be continued......)
