Looking at Chen Wanrong's excited look, Ye Tianheng asked strangely: "My friend, what's wrong with you? Could it be that he came up with a new idea?"

"No need to doubt it, he must have thought of it." Sima Chengzhen said with a smile.

Chen Wanrong nodded and was very excited: "Master Ye, we have something to do again! There is a big thing that we need to do!"

"Oh, my friend, tell me, what is it!" Ye Tianheng asked very much.

Chen Wanrong continued: "Master Ye, with glass, we can not only use it as an analysis tool, but also make a good tool for the army, which can allow the generals to see further. This thing is called a clairvoy or a telescope."

"Qianli Eye? Telescope?" Sima Chengzhen's interest came and asked, "My friend, what is that?"

Chen Wanrong was very excited when he thought about the bright prospect of Tang Jun having a clairvoyance: "Master Taoist, you are a martial arts practitioner. How far can you see if you are poor at your eyesight?"

"This... my friend, you really asked me!" Sima Chengzhen thought, "I can only look at three or five miles at most. If it is a good location and a very good eye. Generally speaking, it can be at most three or two miles at most."

Chen Wanrong nodded and said, "That's it! A person with such good eyesight as Taoist priests can only look at such a distance. If we make a clairvoyance, there will be no problem with ten miles."

How far a telescope can see has a lot to do with the multiple. In order to let the generals see further, Chen Wanrong must have spared no effort and the distance is not short.

"Ten miles?" No one believed it, and everyone looked surprised.

Chen Wanrong said with great affirmation: "That's right, it must be Shili. By the way, Master Ye, there is still some time. Let's quickly make some molds and try some."

"How do you do this?" Ye Tianheng and the others asked immediately.
