A group of alchemists who had no theoretical foundation, but did have some operating experience, were dazzled by Li Chengqian's flickering, and finally got on Li Chengqian's thief ship without knowing what was going on, and began to prepare photosensitive materials in a daze.

Of course, Li Chengqian is not idle in this process, he must watch the scene, and always instruct these novices how to operate and what to pay attention to when operating.

In this way, time passed imperceptibly, until half a month later, all the photosensitive materials and developer were all prepared.

Pieces of palm-sized glass were cut and put together, and a carriage was sealed with all the windows sealed, leaving only a small door to enter and exit.

A hole was made in the carriage of the carriage, in the place of which a convex lens was inlaid and covered with a black curtain.

In liquid development, a special photosensitive material is evenly applied to the glass, and then the image is taken while the glass is still dry, with an exposure time of 5 to 15 seconds.

Then it is necessary to start developing and fixing the image before the glass is dry, and form a negative film on the glass, otherwise all the previous work will be in vain.

Of course, there is no need to pay attention to the fixing, as long as you find a suitable time to photocopy the negative on the glass onto the paper.

These things are simple to say, but they require a certain amount of experience in practice, such as the ratio of photosensitive materials, exposure time, development, fixer preparation, and the time required for development and fixing.

So after everything was ready, Li Chengqian, with the cooperation of the 'master', got into the trunk of the carriage and began a non-stop test against his 'Lanruo Temple'.

The 'master' was completely stunned at this time, and he didn't know what Li Chengqian was doing, only that he was constantly soaking in glass under his command.

This kind of day lasted for about half a month, and finally on a sunny afternoon, a black and white photo of 'Lanruo Temple' appeared in front of me.

"It worked, we succeeded." The excited Li Chengqian scurried around with a palm-sized piece of paper, and the frightened Yang Yuxin thought he was crazy, and chased after him and told him to stop.

"Little girl, look, look, this is where we live!" After Li Chengqian ran around, he handed the piece of paper in his hand to Yang Yuxin, who had caught up.

As a result, the little girl didn't look at it at all, and pulled Li Chengqian and put her hand on his forehead.

"What are you doing, this palace is not sick!" Li Chengqian opened the little girl's hand and continued to hand over the photo in his hand: "Look at this, look at it!" ”

"What is this?" Seeing Li Chengqian return to normal, Yang Yuxin breathed a sigh of relief, took the photo and looked down.

Who knows, after just one glance, the little girl screamed, stammered and asked a little speechlessly: "Your Highness, Your Highness, this, this is ...... It's ......".

"How's that, isn't it clear?" Li Chengqian didn't notice the little girl's pale face, and said ostentatiously.

"Your Highness, you scared her!" Night Charm quietly appeared beside Yang Yuxin, and reached out and pinched her shoulder and back a few times.

Scared? Li Chengqian was stunned for a moment, and then noticed that the little girl was trembling vigorously with the photo, as if she had seen something terrible.

"What's wrong?"

"Your Highness, are you an immortal? Why...... Why is this so clear, so real? Night Charm took the photo from Yang Yuxin's hand, her eyes scanned back and forth between the photo and the hall several times, and asked with some confusion.

"It's called a photograph, and it can get everything on paper in a very short amount of time, and it's exactly like the original." Li Chengqian didn't care if he changed the audience, and the constant excitement made him just want to share it as soon as possible.

Take a picture of yourself, and then find a place to save the photo, and those archaeological guys thousands of years later will have the opportunity to see the handsome Prince of the Tang Dynasty, what a sense of accomplishment!

However, what embarrassed Li Chengqian, when he stood in front of the carriage and wanted to take a selfie for himself, Yang Yuxin and Ye Mei grabbed him and said nothing to let him pass.

"No, what the hell are you two going to do? Do you want to be together? Don't worry, we'll take a group photo next. Li Chengqian struggled and said a little dejectedly.

"No, Your Highness, this thing will absorb people's souls, you must not take a photo!" Compared with Yang Yuxin, who was a little flustered, Ye Mei's mind was still very clear, and the meaning was also very clear.

"Huh?! Sucking souls? Says who? Li Chengqian was a little stunned.

"If you don't absorb the soul, then why does the main hall appear on paper?" Night Charm shook the photo of 'Lanruo Temple' in his hand and said.

"Nonsense, this is simple physical imaging, the same as the principle of printing, have you ever heard that printing sucks people's souls?" Li Chengqian said with some tears and laughter.

In later generations, I heard that when the camera first appeared, many people were afraid that their souls would be sucked into that small box.

When I watched it at the time, I thought it was a, some people made it up, but now looking at the performance of Yemei and Yang Yuxin, it seems that this statement is not groundless.

Li Chengqian spent about a cup of tea trying to convince Ye Mei, but in the end he found that everything was in vain, and in desperation, he turned his gaze to the 'master' who was standing on the side: "You come, stand here!" ”

"No, no, Your Highness, Your Highness spares your life!" The expression on the 'master's face instantly turned pale, and the fear that had not appeared before Li Er was in prison enveloped his body.

He is a character who wants to ascend to immortality, so he is not afraid of death, but if he imprints his soul on that glass piece and is trapped in it forever, this is something he will never accept, he can die, and he doesn't want to be trapped.

Xiucai's indescribable feeling when he met the soldiers made Li Chengqian feel a little broken, just taking a photo, how could he do it like killing the whole family.

Dragged Ye Mei and Yang Yuxin aside, the three of them negotiated, and finally reached a consensus, go to a Turkic slave, use the slave as an experiment, and see if the slave will die after taking pictures.

So the group caught up with the carriage and went straight to the medical school, where there were still some finishing touches to be done, and some Turks were working there, and when the time came, just take a picture and everything would be revealed.

However, many things happened by coincidence, Li Chengqian and the others' carriage had just left the 'Lanruo Temple' before they reached a hundred steps, and they were blocked halfway by the old man with a group of people, and Lao Li's face was full of unhappiness: "Rebel, what are you going to do?" ”
