Everyone who came to watch the fun knew that the so-called ultimate truth of heaven and earth was just a gimmick, but it was just a gimmick created by Li Hao to raise the price.

However, his skills are not as good as others. Even if he knows that he will be deceived, he can only grit his teeth and endure it.

Especially Li Ji, his face was full of constipation.

The telescope after the failure was passed back and forth in the hands of everyone, and finally fell into the hands of the old man Li Gang. The old man held it and looked at it for a long time, then put it down, waved to Li Hao, open his mouth that was almost without a few teeth, and asked with a smile: "Little Friend, how about telling me the truth?"

Li Hao immediately leaned over to the old man and smiled apologized: "Oh, old man, just call me my name. My friend... I can't afford to take care of him."

The old man is over 80 years old and has long passed the age of no exceeding the rules. Even if Li Er sees him, he has to arch his body to speak. Even if Li Hao is brave, he will not dare to show off in front of him. Otherwise, this old man would not have to do anything. With his eyes, Li Jing could kill his relatives for justice.

Li Gang nodded with a smile: "Haha, it's not bad, polite, and a good boy."

"Hehe..., then look." Li Hao was shameless and almost smiled on his face.

"Then tell me what happened to Qianliwang? Why did it lose its effect after changing a few iron pipes? What's the reason?"

The old man was very angry when he spoke. Many people heard it and they couldn't come forward to listen.

Li Hao glanced at the old guys who wanted to take advantage of the situation with contempt, and coughed dryly, "Old man, do you know the principle of imaging?"

"Principle of imaging?" Li Gangshou frowned tightly, trying to return what he had learned in his life, and finally shook his head: "I am a little ignorant and unaware of it."

"This..." Li Hao scratched his head in embarrassment, and scraped his stomach and thought about how to tell it in a way that the old man could understand. If the old man didn't know the principle of imaging, he would definitely not know the principle of refraction. How should he explain this?

The old guys who surrounded him were all knowledgeable people. After thinking hard, I still don’t remember any book that talked about the principle of imaging.

Although Li Gang was old, he was not confused. Seeing Li Hao in a dilemma, he thought he didn't want to say it, so he smiled and ran over to him and said, "Boy Dejian, it seems that I have made a big deal. It's okay, since you don't want to say it, then forget it."

"Uh..., it's not that I don't want to say it, old man, I don't know what to say." Li Hao smiled bitterly and said, "Why not do this? I'll always do an experiment for you, and you will understand after seeing it."

"please."

In front of everyone, Li Hao took the telescope from the old man, took off the convex lens in front, and asked someone to take a piece of paper and put it on the ground. After adjusting the distance between the convex lens and the paper, a dazzling spot appeared on the paper.

"Hey, what's the hell that this guy sells?" Cheng Yaojin observed Li Hao's actions throughout the whole process, and asked with confusion at Li Ji beside him.

"How did I know?" Li Ji answered angrily.

What happened just now was too embarrassing. Don’t know what Li Hao was doing, even if he knew, he wouldn’t dare to say anything.

Just when Lao Cheng was about to continue saying something, he heard Li Chengqian exclaim with a ghost-watching expression: "It's on, it's on fire."

Fired? What's the fire?

When he put his attention on Li Hao again, he saw that the paper on the ground had already smoked, and a wisp of flame was rising little by little, and the paper on the ground was burning in less than a short while.

What's going on in this? Are you a hell?

The boy obviously didn't have any fire-burning thing in his hand, so how did the paper burn?

The old guys looked like they saw a ghost, and the boss with his mouth wide open, and some of them could almost put an egg on them.

Old Li Gang was also startled, his hands trembled, and his beard was torn off several pieces, but the old man no longer cared about it and asked nervously: "What's going on? Li Xiaoyou, could it be... Could it be that I can't do the magic? Why did this paper spontaneously ignite without fire?"

Li Hao's eyelids were pounding wildly. Why can't these old guys grasp the key points? The key to my experiment for you is to make you pay attention to distance, not whether the paper will burn.

He smiled bitterly: "My grandpa is not a fairy method, it is called science, and what do you think this paper will burn?"

Because? It’s not because of the thing in your hand.

Things that can make fire with empty hands are definitely magic weapons for immortals. From this perspective, a telescope of 500 s is not very expensive.

Li Jing stood outside the circle, and suddenly someone patted his shoulder. When he looked back, he found that it was Li Daozong.

The old guy looked gloating: "Old Li, your baby is indeed a prodigal son. Such a treasure will be sold for 500 cents. If I have such a son, I will break his legs when I go home."

I..., Li Jing, who was already a little bit painful, wished he could not give him a punch.

If I had known that Qianliwang had such an immortal treasure, even five thousand guan wouldn't be sold?

Li Jing thought in pain, and his dark face was almost the same as a disaster.

The other old guys were not like this. They were all excited and ready to fight. In order to prevent Li Jing from regretting it, Li Er took the initiative to speak: "Li Dejian."

"I'm here!" Li Hao replied.

Li Er asked in a deep voice: "One is five hundred stakes a thousand miles away, right?"

"Uh..." Li Hao was thinking about what Li Er meant and whether he had to reduce the price, the old man Li Jing went out: "Your Majesty, I just talked nonsense, I hope Your Majesty won't take it to heart."

"Medical Master, there is a way of saying a gentleman is hard to pursue, and people cannot speak without trust." Li Er showed a happy expression on his face and stared at Li Jing and said, "Just just now, this kid clearly said one of five hundred kilns. Could it be that the pharmacist wants to renege?"

Hey? Li Hao, who was listening, was stunned.

What I mean when Li Er said is that he thinks that a telescope of 500 s is quite cheap?

Just as he was thinking, Li Er said again: "Li Dejian, five hundred jins are a thousand miles away. I promised you and I will send you ten to the palace."

"I also want five, and it's also 500 trump cards. Li Dejian, you can apply for this price, don't regret it."

"Yes, whoever regrets who is the grandson, I also want two."

"I want four."

“Two.”

"Hehe, it's cheap. This kind of treasure is actually 500 yuan per person. Why did Old Li give birth to such a prodigal son? Hahaha... Li Dejian, I have ten."

"I guess this old guy Li Jing will regret it to death when he comes home. Forget it, no matter what, boy, don't forget my five."

The old guys were all very enthusiastic. The little old man Li Gang opened his mouth several times but couldn't speak at all. In the end, he was even squeezed out of the circle.

In the circle, there were about a hundred telescopes sold in the blink of an eye, but in the end, Li Hao was afraid to sell them.

These old guys are crazy!

Is it cheaper to have a telescope of 500 stakes per person?
