On the west bank of the Tianxin River, the large area of reeds that Li Xi and Xiao Sheng had groped for had been cut down, and the former Ming Zhai Fort where the bandits had hid could be seen from a distance. But compared to before, it is no longer alone, weather-beaten. A circle of wooden houses stood around the walled fort, and people came and went in between, and there was no bleak scene before.

A young man in a Yao costume rushed back from the bank of the river, running on a gravel road that had not yet been paved, and hit the people who were busy ramming the road on the road staggered, most of these people wore gauze hats, and scolded angrily one by one, and some people were trying to chase the kid, but they were stopped by others.

"Look who's coming?"

In a whisper, the hat-bearers bowed down to the side of the road, knelt down one by one, and without saying a word, clubbed their heads on the ground, even if they had just been paved with gravel.

A man in a light blue shirt and a small hat for the sun approached leisurely, and two teenagers followed behind him with things. Although the face of the person in front of him was not clear, the people on the side of the road recognized the two teenagers behind him, Yu Hanyi and Luo Tangyuan, the two often come here, and everyone knows that they are the guards of Qingtian Company, although they are not more familiar than Jia Hao and Wu Ya, but they are not ordinary guards.

"Look who's coming!"

The young man in Yao costume rushed into the largest wooden house outside the walled fort, and the people crashed into the house with a shout, which frightened the long-standing woman inside and let out a low breath.

"Panshi Jade! If you're so messy, you'll be washing all the toilets next month! Isn't it time for you to practice pins, you know how to be lazy......"

Pan Jinling angrily dropped the medical book and began to nag with a straight face.

"Who did you say was coming?"

It took her a while before she came to her senses.

"Oh, if you knew you would worship me as a Buddha, I wouldn't have come......"

The words sounded, Pan Jinling's body stiffened, and then Li Shi entered the house, wiping the sweat on his face. It was the first time he had come to the leprosy hall after it had been built, and the lepers who had been cured by Tripterygium Terygium had bowed down to him all the way, which really made him unbearable.

"Four...... Fourth brother. ”

Pan Jinling called in a low voice, and then his apricot eyes were round, and his bright eyes were full of melancholy.

"How can you come here!? Although there are cured patients outside, there are still serious patients living in the fort, and you are too ......."

Li Xian didn't pay attention to her nagging at all, and with a wave of his hand, Yu Hanyi handed a box he was holding to Pan Jinling.

"What is this?"

Pan Jinling took out a strange thing from the small wooden box covered with straw, the heavy iron base, and propped up a horizontal iron sheet, and there was a hole in the middle of the iron sheet, as if it was not a hole...... Li Shi looked left and right, and directly stretched out his hand to pull out the top of Pan Shiyu's head, and the young man groaned, covering his head and looking at him aggrievedly, not understanding why he pulled out his hair for no reason.

The hair was placed on a small table under the iron sheet, on which was a white porcelain piece, and the strands of hair were clearly visible.

"Put your eyes on the holes and look at them."

Li Xi smiled and said, Pan Jinling frowned, she was not a little girl, and at a glance she could see that there was something very strange hidden in Li Shi's smile, as if she was waiting to see some big joke. Forget it, no matter what foreign appearance she wants, she will not refuse Li Shi's request.

Gritting his teeth as if he was about to go to the altar, Pan Jinling's eyes rested on the small hole.

"What? Nothing, huh? ”

Seeing that her eyes were dim, she spoke suspiciously, Li Xi patted her forehead, lit the oil lamp, and came to the side of the porcelain table, but the flames shook, and Pan Jinling still didn't find anything. Li Xi had to beckon Yu Luo and the others to put down the screen window to block the wind, and the flames stabilized.

Pan Jinling put his eyes together again, and was silent, strangely silent, for a long time. Li Xi was about to scratch his head, thinking that he had failed in the trick, when an elongated scream suddenly sounded in the room, and Pan Jinling jumped up like a cat that had been stepped on by its tail, and hit the wall with a few steps, covering his chest and panting.

"That'...... Is that...... Is it hair!? ”

She looked at Li Shi with a look of horror.

"To be precise, it's the image of the hair that is magnified more than 100 times."

Li Xian said leisurely, and then looked at Yu Hanyi, "Look, other girls can withstand the fright more than you, but your eyes rolled at that time." ”

Yu Hanyi's face suddenly turned red: "What the general secretary asked me to see was a mosquito head!" ”

Pan Shiyu's eyes lit up, and he quickly came over to look at his hair, and then let out a whoast of admiration.

Pan Jinling had already eased up, and her apricot eyes were as bright as lights: "God! Oh, my God...... What is it? How can you expand the image of something so big!? ”

Li Xian frowned for a while, as if he was hesitating about what name to choose, and then shrugged helplessly: "This is called...... Microscopes, very primitive microscopes. ”【1】

drove Pan Shiyu away, Pan Jinling had no teacher, lost his hair, put a piece of gauze on the porcelain platform, and then also issued a pan Shiyu-like wow admiration.

"God, fourth brother, you still say that you are not a god! Isn't this a treasure that only immortals have? ”

Then her reaction made Li Xian cry and laugh.

"There was also a note in the box, a general description of the other world. I need you to use this thing to see another world clearly, believe me, when you see clearly, understand the relationship between the mirror world and human diseases, you will also become a god. ”

Li Shi said his expectations, and asked Pan Jinling to only treat leprosy patients in the leprosy hall, but he really buried the only internal medicine doctor he had on hand. It just so happened that the optical glass came out, and in addition to selling it for money, he immediately asked Wu Zhong to make water drop glass beads, which was the perfect lens for Leeuwenhoek's microscope. With this tool, Pan Jinling, an internal medicine doctor, should embark on a completely different path as a doctor.

"Heavenly ...... Oh, my God...... It's amazing......"

Pan Jinling was stunned by the huge surprise, and her whisper was like a torch, suddenly illuminating a chaotic corner of Li Xian's heart.

"You say...... God is wonderful? ”

Li Shi frowned and asked.

"Isn't it? I thought that the world was what we saw with our naked eyes, but I didn't expect that it was really a grain of sand that could see a world! God created things, I really don't know how amazing, we mortals, far from understanding the mysteries of heaven. ”

Pan Jinling said in confusion, but Li Shi was stunned.

"Heavenly ...... Oh my God, mystery...... Heavenly Dao ......"

His eyes lit up.

"I figured it out!"

Li Xi became more excited than Pan Jinling, pinched Pan Jinling's shoulder, and shook it vigorously.

"That's not humanity, that's the way of heaven! All I have to do is go with the ...... No, do the right thing for heaven! ”

Pan Jinling, who was almost rubbed into Li Xian's arms, finally pulled his mind back, but immediately swung to another high point. Seeing that the delicate face close to her was showing a stunning momentum, her face was flushed, and the faint scars on her cheeks were all hidden, and her eyes were floating, as if her whole body had lost its center of gravity.

"I want to retreat!"

Li Yan shook for a while, threw away the Panjin Bell and turned to leave, didn't take two steps before he remembered something, took out something from the box that Luo Tangyuan was holding, and threw it to Panshiyu.

"For you, if it doesn't fit, come and change it!"

A pair of leather boots smashed on Pan Shiyu's body, and the sisters and brothers both watched Li Yan roar away with a dull expression, and Yu Hanyi and Luo Tangyuan hurriedly caught up.

He ...... hugged my sister. ”

Pan Shiyu said dumbfoundedly.

"Closed ...... Shut up ......"

Pan Jinling propped up the table and said weakly.

"He hugged his sister."

Pan Shiyu emphasized.

"You! Don't you want to study medicine, so you want to repay him as a guard? Why are these boots for you? ”

Pan Jinling opened the topic, Pan Shiyu also came back to his senses, looked down at the boots in his hand, cheered, and rushed out of the house with the boots in his hand.

"He didn't do it on his mind...... Is it? ”

When Pan Shiyu left, Pan Jinling hugged his shoulders and muttered in a low voice, as if he wanted to keep the feeling on his shoulders.

"Sister Xiao, Sister Xiao, have you forgotten your name, have you ever been sick? You're still thinking about him...... You are too content, too shameless. ”

Reading his real name, which he had never mentioned to anyone, Pan Jinling's face turned pale and he muttered to himself sadly.

"You should understand his intentions, why he gave this place that name."

His eyes turned to the microscope brought by Li Shi, and his dilated pupils gathered.

"He opened the door of the Heavenly Dao for me and let me go down the Heavenly Dao, and I was still delusional......"

Pan Jinling's face calmed, he took a deep breath and held the microscope.

"Since he has set a fate for me, I will do everything to see the world under the mirror for him."

On the gravel road, Li Xian hurriedly walked forward, Yu Hanyi and Luo Tangyuan followed, neither of them made a sound. When passing a big stone, Luo Tangyuan glanced at the three big characters engraved on the stone again, and finally couldn't help it.

Luo Tangyuan asked: "I haven't figured it out, why does the head secretary call this place the Valley of Despair?" ”

Yu Hanyi frowned: "I asked earlier, and the general secretary said that there is a broken intestine grass here." ”

The two young shrugged blankly.

They were at a loss, but Li Xi was confused.

Back to Zhuangzi, who has been accustomed to being called "Li Zhuang", Li Shi hurriedly summoned several directors, although they were still busy with their own affairs, but everyone was used to Li Shi's ups and downs, and even looked forward to it, usually he would be like this, all because he wanted to stretch out that little golden finger.

"Liulifang makes such a glass cover, you don't have to grind it carefully, it is thinner than the plate, pay attention to adjust the annealing time. Uncle Guan's iron shop creates such a thing, with a pig iron base, wrought iron lid and handle, He Gui makes such a twist wheel mechanism, the general principle is like this, and the details are integrated and pondered. ”

Li Shi said while drawing on the paper with thin charcoal strips, the pattern gradually became complete, and after looking at it for a long time, He Gui could barely see it: "This is...... Oil lamp? ”

Li Shi said with a smile: "It won't shake, it won't be blown out by the wind, and it can be carried away at any time, even on a horse, or it can be called ...... Horse lantern. ”

Everyone looked at each other, this ...... It's not a rare thing, is it? Isn't it the same with the gas death lantern?

"Wait, with a glass cover, the light is much stronger than a lantern candle, and the oil lamp is afraid of shaking and the wind going out."

Tian Dayou hurriedly excavated the value, and this was also true, and everyone nodded one after another.

But looking at Li Xian's face with excitement, it seems that this oil lamp is of extraordinary value, which also puzzles everyone.

"Fourth brother, this thing...... Not worth a few bucks, right? ”

Tian Da was angry, this kind of thing that can't be sold for a few dollars of silver is not eye-catching.

"It's valuable, it's not just valuable, it's the light ......"

Li Xian's eyes flickered, and his mind seemed to be cast into another world. The horse lantern was just inspired by the shaking of the oil lamp when he showed the microscope to Pan Jinling just now, but the greater inspiration came from Pan Jinling's words, and from this great inspiration, he easily got the horse lantern out as the first experiment.

"In this dark era, Li Xi said, there must be light ......"

He whispered.
