At night, everyone who had eaten and drank enough left.
The place is left in a mess, waiting to be slowly cleaned up tomorrow.
Go outside and see off Yuan Dake and Zhang Bao. Sun Simiao and Xiao Han walked back from the path side by side, and the moon was full in the sky.
"Xiao Han, what's going on today? What's the matter with you?" Sun Simiao thought for a long time and finally asked the same question as Yuan Dake.
Xiao Han shrugged and said casually: "It's okay, I just haven't seen each other for a while. Let's get together and catch up on old times."
"Inviting them is just to reminisce about old times, nothing else?" Sun Simiao looked at Xiao Han suspiciously, as if he didn't believe it.
People who are too smart are like this. Every little thing others do and every move they take seems to have another meaning in their eyes.
So many misunderstandings in reality are created by these smart people themselves.
"What's the point of me? I'm just an idle prince. Chang'an has almost forgotten me now." Xiao Han grinned, but he didn't look depressed at all.
Not seeing anything from Xiao Han's face, Sun Simiao shook his head and smiled. He decided it was Xiao Han, but he didn't bother to investigate.
"By the way, I found a place on the edge of the Qinling Mountains, which is very similar to where you found the Panax notoginseng bush. The Panax notoginseng we brought back have been planted. If they survive, Daniel will go to the Qinling Mountains again and plant the Panax notoginseng. Dig up the remaining Panax notoginseng and medicinal herbs and plant them together. If everything goes well, in two years, this medicinal material will become a large scale." Sun Simiao changed the topic and told Xiao Han about the Panax notoginseng brought back from Qinling Mountains. After all, Xiao Han also worked hard for them and should know these things.
Xiao Han heard it, but just nodded indifferently. When he thought about it, as long as he was not allowed to go to that damn place again, Sun Simiao could do whatever he wanted!
Slowly taking two steps forward, seeing that Xiao Han was silent, Sun Simiao raised his head and looked at the Qinling Mountains in the distance and said, "Also, I am going to move to Qinling Mountains with Danniu in two days, so that I can take care of the medicinal materials."
"oh……"
Xiao Han didn't pay attention to this sentence at first, and still nodded habitually.
But as I clicked and clicked, I suddenly felt something was wrong. I chewed over what Sun Simiao had just said, and almost jumped up from the ground with excitement: "What? You want to move to Qinling Mountains?
Sun Simiao didn't expect Xiao Han's reaction to be so violent. He was startled by him in the middle of the night. Then he stroked his chest and said displeasedly: "What are you doing? What a shock! These medicinal materials are so precious, how can they be taken care of without anyone?" ?”
"Then you don't have to go in person!" Xiao Han was anxious! Pointing in the direction of the Qinling Mountains, he said: "What if we encounter a one-horned rhinoceros again, or a tiger or leopard? No, no, it's too dangerous!"
Sun Simiao looked at Xiao Han's worried look and was a little moved. He coughed twice and said, "Actually, you don't have to worry too much about this. We chose the edge of the Qinling Mountains this time! There won't be anything like what you said."
Xiao Han glared at Sun Simiao and waved his hand fiercely: "That's not possible! A few days ago, a wild boar was killed near here. Didn't you see that walls are being built everywhere now? Are you afraid of wild beasts from the Qinling Mountains?"
Xiao Han was really anxious, especially after experiencing the Qinling Mountains personally, he was even more afraid that something would happen to Sun Simiao in the Qinling Mountains!
Moreover, in Xiao Han's heart, there is no such thing as a friendship between him and Sun Simiao that is similar to a year-end friendship. Even in medicine, Sun Simiao could not tolerate losses. This microscopic world had just begun. If people disappeared, where would Xiao Han go to cry?
"Anyway, I don't agree with this! There are many people here who are more familiar with Qinling than you. For example, that Liu Zi is very good! We will recruit a few more people tomorrow, and they will definitely be more professional than you and Daniel! Besides, if there are people around here, I have a headache and want to go to the Qinling Mountains to look for you? Isn’t it troublesome? What if I don’t find you and let a wild beast carry me away?”
While Sun Simiao had not yet made up his mind, Xiao Han finally gave up Sun Simiao's idea with all his persuasion. After sending him back, Xiao Han looked up at the bright moon in the sky until the door was closed tightly, and sighed: "Hey, what's the matter with this? Each and every one of them makes people uncomfortable."
Sunset and sunrise, time remains the same.
After returning home, Xiao Han finally got his wish and lived the life of a pig, sleeping when he was full and eating when he was full.
compass.
This thing was made two days ago.
Xiao Han originally thought that the magnets were difficult to find, but as soon as he told Sun Simiao, he went back and took out two pieces from the medicine box and threw them at Xiao Han's feet.
Looking at these two palm-sized magnets, Xiao Han's eyes almost fell out! After chasing Sun Simiao for a long time, I realized that it was still a medicinal material.
I thought it was weird to use rhino horn as a medicinal material, but I didn’t expect that this stone could also be used as medicine!
Xiao Han couldn't help but stand in awe of the great medical martyrs, but he didn't know how the first person who discovered that they could be used as medicine tried it? Is it like Shen Nong, who directly chews it with his mouth? Can it be chewed?
I can’t understand it, and I can’t think about it anymore! If I think about it again, my teeth will be sore.
Roll up your sleeves, break the magnet into small pieces, grind it into elongated prisms, hold a copper needle in the middle, and you have a simple compass!
No matter how it turns, the prismatic magnet still points to the south tenaciously under the powerful laws of physics! The onlookers were so shocked that their jaws almost dropped! Everyone looked at Xiao Han with more and more awe!
However, Xiao Han is still not satisfied with this! Because it is too inconvenient to carry around. If you touch it lightly, either the magnet will fall off or the needle will fall off!
He originally went there for the quality of military supplies, but now that it's like this, he can't let the generals fight half the battle. Let's stop looking for parts for now...
Improvement, must be improved!
I found a coppersmith and melted a lot of copper coins in one go, making a bunch of small round cups.
Regardless of the coppersmith's confused look, Xiao Han pointedly directed him to weld the special thimble in the middle of the cup.
The magnetic needle was punched in the middle, fixed on the copper needle, and then filled with clear oil. Originally, he wanted to use glass for the lid, but Xiao Han couldn't wait any longer, so he took out the leftover crystal scraps and used isinglass to attach it to the copper cup.
A military version of the compass that will never malfunction no matter how it is turned is taken shape.
He happily took the newly made compass to show off in front of Sun Simiao, but came back empty-handed...
This old man is simply more shameless than a robber!
He said that he would need it when he went to the mountains to collect medicine in the future, so he felt at ease and snatched the compass from Xiao Han's hand, and he even had the nerve to ask for one for Daniel...
I returned to the workshop angrily and started making again according to the steps just now!
Fortunately, there are still a lot of magnets left in the copper cup. The only thing that is not enough is the crystal piece. Just wait until Xiao Han writes to Chang'an and ask him to send glass pieces here.
I kept two of the remade compasses for myself, and packaged the rest and gave them to Li Shimin, hoping that these gadgets could help him a little.
