In this way, it was too late to tell the matter after arriving in the Valley of the Medicine King. Next, Jumping Bead wanted to go back and talk about the safety issues along the way, but when he thought about it, he must have driven the plane straight to the Medicine King Valley along the way, except for stopping to refuel, or buying some daily necessities, he should not stop too much on the way.

Moreover, Jumping Bead thought about it, and felt that it was better not to talk about the safety issues on the road, because if the young master mistakenly thought that he was reluctant to let him travel far because he said too much, it would make the young master feel very troubled. The young master cares about his wife very much, and at the same time, he also cares about his own feelings as a maid, which is very clear. Therefore, in order not to make the young master feel in a dilemma, Jumping Bead decided to change the topic and stop saying those words that would bother the young master.

However, although Jumping Bead made a lot of determination, when the next sentence came out, she found that many things are not something that you can definitely do if you make up your mind!

"Young master, let Tietuo help me build a walkie-talkie. When you're gone, I'll ......"

Obviously, he was very reluctant to let He Wei go, but Jumping Bead never said "don't go", or "take me with you" and so on. She tried her best to hide her true thoughts, but that worry and reluctance would always be revealed inadvertently.

"Okay, before I set off, I will definitely let Tie Yan make the best walkie-talkie for you!" He Weiqiang promised with a smile. Jumping beads responded to He Worry with an equally reluctant smile, and a back that gently shrugged his shoulders and left silently.

Jumping beads didn't get the answer she wanted, so she sobbed and left. And although He Wei knew what kind of answer Jumping Bead wanted, he pretended not to know and deliberately gave Jumping Bead a promise that she didn't really want.

"You should know that she actually wants to go with you. Xiao Jiu said.

Yes, asking for a walkie-talkie or something, in fact, is just a hint of jumping beads. I want He Wei to take the initiative to offer to take her and go to the Medicine King Valley together.

"Take her with you, don't be kidding, okay?" He Wei smiled bitterly, "Although we are going to fly the plane all the way to the Medicine King Valley." However, what kind of danger will we encounter along the way, and whether we will be able to reach the Medicine King Valley smoothly, is still unknown! If we take the jumping bead and go on the road together, in addition to putting one more person in danger with us, what help will it help us to form?"

"At least...... Have someone around you to help you prepare three meals a day. Xiao Jiu found a very reluctant reason, so reluctant that even it was difficult to accept. Therefore, Xiao Jiu paused for a moment and then continued, "Moreover, you can't deny that the current cultivation of the jumping bead is much higher than yours, so if we really encounter any danger on the road." Cultivating to be a jumping bead that is higher than you, it is definitely more reliable than you!"

"Hah, who told you that if you are a high cultivator, you must be reliable?" He Wei asked Xiao Jiudao rhetorically, "Do you think that if there is any danger at that time, what use can jumping beads be except for recklessly repeating the front and acting as a shield for us?"

Xiao Jiu couldn't answer the question, so he could only be silent. Because, according to the character of Jumping Bead, she is not a person who is good at solving problems with her brain, and she cares more about the safety of He Wei than about herself. Therefore, if you really worry about what you say, if you encounter any emergencies, the first thing that Jumping Beads thinks of must be to rush up and protect You Worries behind you, as for whether you can protect it, what to do if you can't protect it, it is not considered at all for Jumping Beads.

"Moreover, when we go, what we will face is the real Zhong Ling Continent Cultivation Realm. Do you think that if something really happens to us, how much of a role can a little girl in the late stage of the Bigu Realm play?" He Wei asked.

Although Xiao Jiu wanted to say that as a cultivator who had only cultivated to the early stage of the Bigu Realm, he really had no qualifications to look down on the jumping beads who had reached the late stage of the Bigu Realm. However, after thinking about it carefully, Xiao Jiu still didn't say anything after all.

Because what He Wei said is indeed reasonable, in the face of the Hidden Dragon and Crouching Tiger's Zhongling Continent Cultivation Realm, a mere cultivator in the Bigu Realm will indeed not have much sense of existence.

"Then what now? In order to make her less sad, you are going to ask Tie Yan to help her build a 'good' walkie-talkie?!" Xiao Jiuyu asked sarcastically, the word "good" was particularly heavy.

"How good, of course it's the best!" He Wei replied with a smile, "Do you think that with our existing conditions, we can build a picture tube?"

"Visible ...... CRT?!Are you trying to ...... Build a videophone?!" Xiao Jiu asked with a little surprise.

"That's right. No matter how good a walkie-talkie is, it's no match for a videophone that can both read and speak, isn't it?"

"Definitely. If it's just to build a walkie-talkie for Jumping Beads, even if it's a good walkie-talkie, it's just a good walkie-talkie. Moreover, when chatting, you can't see the other person's situation at this time, but it is easier to have a sense of distance. Xiao Jiu echoed, "If you change it to a video phone that can both see and speak, the result will be completely different, and it will give people the illusion that the other party is actually by their side and very close to themselves." ”

"Yes. He Wei hummed softly, and then asked again, "How is it, can it be made?"

"There is a certain degree of difficulty! Because with our existing conditions, it is impossible to build a stereo imager, so we can only consider using ancient imaging technology. Xiao Jiu said, "Moreover, in ancient imaging technology, it is difficult for us to make micro light-emitting diodes and liquid crystal screens, which are necessary for manufacturing color screens." Therefore, with the existing conditions, we can only build an imaging device with a black and white screen. ”

"Black and white screens...... That looks a lot less realistic, doesn't it?" asked Ho Wei. Although He Wei has learned about the development history of picture tubes, LCD screens, and so on from books. However, for He Wei, who has been using stereo imagers since birth, those things are too far away for him, so he does not have a very intuitive understanding of the words said in the books.

"Yes. If the screen is black and white, the imaging effect will be very distorted. When this imaging technology was applied to a type of home appliance called a black-and-white TV, the effect was as follows. Xiao Jiu said as he used the stereo imager to show the appearance of the legendary black-and-white TV.
