Dong Yun ran out with Liu Yong, but she has long been accustomed to these "beautiful scenery", but she doesn't have so much emotion from Liu Yong, listening to Liu Yong's question, she was slightly stunned, thought about it and said: "After the sunrise is day, after the sunset is night, right?" ”

"Yes. Pen ~ Fun ~ Pavilion www.biquge.info" Liu Yong looked at the sunset that was about to dissipate, and said softly, "So the sunrise gives people hope, and the sunset is sad." 'The sunset is infinitely good, but it is just near dusk', this poem is beautiful, but unfortunately it is too decadent, I still like another sentence, 'Mo Dao Sangyu is late, for the sun is still full of sky'. ”

Dong Yun hadn't read a book, so she had to look at Liu Yong talking to herself there, listening as if she didn't understand, but she heard Liu Yong ask again: "Yun'er, do you think the morning glow or the sunset is good-looking?" ”

Dong Yun said strangely: "It's all good-looking." If you don't look at the hour, who knows which is the morning glow and which is the sunset. ”

"Well, that's what I thought, too." Liu Yong nodded in agreement, and said, "Yun'er, let me tell you a story." A love story related to Caixia. ”

"Okay." Dong Yun said happily, "Big brother hasn't told me a story for a long time. ”

"That's because it's too busy." Liu Yong said with a smile, "It's rare that we have such a free time, so big brother will tell you about it tonight." ”

The two of them returned to the cave, moved the fire a little out of the hole, and then spread pine needles and bamboo leaves on the ground just now.

"This story is called 'The Sky is Full of Colorful Clouds.'" Liu Yong cleared his throat and began to speak. "The Sky is Full of Colorful Clouds" is the only Qiong Yao novel that Liu Yong has read in books in his previous life, and it is said to be based on a true story. At that time, Liu Yong had just entered high school and stumbled upon the novel at a relative's house. In fact, this is also a relatively old-fashioned story, a couple who know each other and fall in love, childhood sweethearts, after a few setbacks and tribulations, finally achieved a complete love. This extremely sensational love story is very attractive to Liu Yong, who is just starting to fall in love, and Dong Yun, who is also drunk at this moment.

Liu Yong can't remember this story too carefully, and there are two paragraphs in his deepest impression, one is what Qiao Yunfeng said when he saw the oil painting with Caixia as the background painted by his son Qiao Shupei for Yin Caiqin, "Have you noticed Caixia in the background?" There are two kinds of rainbows, the morning rainbow is followed by day, and the evening rainbow is followed by night. The colorful glow behind me is the colorful glow of dusk. What heart-wrenching words these are, and what kind, helpless, and reluctant feelings they are; The second is that there is such a paragraph in the letter written by Qiao Yunfeng to his son, "The Caixia at dusk and the Caixia in the morning are the same. For a couple who truly love each other and stay together for life, they must not only share the dynasty, but also share the twilight!", how touching and joyful this is.

Dong Yun's tearful eyes were full of smiles, she liked the happy ending of this kind of love. However, Dong Yun has more of her own questions, "I sympathize with Yin Caiqin, but I don't like this person." ”

"Why?" Liu Yong was puzzled, "Yin Caiqin is strong, considerate, generous, and gentle, isn't it good enough?" ”

"It's not these." Dong Yun's face flushed, "How can she be so shameless, living with Qiao Shupei without getting married, it's too embarrassing for our woman." ”

Liu Yong sweated profusely for a while, and had to explain that this was a custom in other countries, but Dong Yun still didn't believe it. Liu Yong had no choice but to surrender, "Okay. It's all up to you, what do you say? ”

Dong Yun was happy for a while, and said with a smile: "Tell me another story." ”

Liu Yong glanced at it and said, "It's okay to talk about it separately." But in order not to make you too excited to sleep, I can only talk about something that is not so attractive. Dong Yun nodded reluctantly, and Liu Yong told a few more stories, and sure enough, Dong Yun listened and gradually fell asleep.

Liu Yong breathed a sigh of relief, but it was difficult for him to fall asleep, first, because he did not have the habit of going to bed early, and secondly, he just took advantage of the hard-won leisure to plan for future development, especially economic development. He also had another thought in his heart, and that was hygiene, which was too important.

Why didn't the average life expectancy of ancient people be long? There are many reasons, poor medical conditions, underdeveloped medicine, especially the lack of correct understanding of the causes of disease, no good hygiene habits, and no concept of prevention of diseases, especially infectious diseases, so once an epidemic occurs, it spreads very quickly, and the mortality rate is particularly high. And even more so for the elderly and children who have lower resistance. Of course, these must be built on the basis of solving the problem of food and clothing, and now even survival is a problem, where is the hygiene habits?

Liu Yong sighed to himself, forget it, take your time, and solve the problem of non-combat attrition in the army first. At that time, the army did not pay attention to health care, prevention and disinfection, and there was no concept of antibacterial and anti-inflammatory, and diseases were common, and if it was a major epidemic, it would often cause a large number of illnesses and even deaths due to mutual infection, which was also one of the important reasons for Cao Cao's defeat in the Battle of Chibi.

"There are no vaccines, no antibiotics, but there are many Chinese herbal medicines that have antibacterial and anti-inflammatory effects." Liu Yong was excited, "Tomorrow, I will arrange for all the students studying medicine in Huatuo to dig and prepare some disinfectants and anti-inflammatory drugs in case of emergency."

The more Liu Yong thought about it, the more beautiful his heart became, and when he saw Dong Yun sleeping very sweetly in the flickering firelight, a feeling of warmth suddenly rose in his heart. This little girl doesn't worry about me at all! I stayed in a cave with her and didn't come back all night, I don't know if anyone gossips? Liu Yong thought for a while, I'm nothing, I'm still a big girl. He is not afraid of shadows, and General Guan Yuguan has not been forced to live alone with his two sisters-in-law, and it has not had any bad impact on their reputation. No matter, sleep!

Early the next morning, the sound of birdsong outside the cave woke Liu Yong from his sleep. At this time, the sky was already bright, Liu Yong turned his head to see that Dong Yun was no longer there, the firelight was flickering on and off, and there were two warm steamed buns and a piece of barbecue next to him. Liu Yong stood up, stretched his waist, drank saliva and rinsed his mouth, held steamed buns in one hand and barbecue in the other, and slowly paced out of the hole. The air here is really fresh, Liu Yong inhaled it heavily, such a day is not bad.

"Big brother woke up?" Dong Yun looked at him with a smile.

"Hmm." Liu Yong replied while eating, "What is Yun'er looking at here?" ”

"I'm wondering how we're going to get down."

It is impossible to climb up the Iwahara Road to return, and the only way to leave is to go down. But how to go down? Liu Yong looked at it, this platform is at least three or four hundred meters below, and with the current length of the rope, it is definitely impossible to go down at one time. Fortunately, there are many pine trees growing on the cliff wall, so it is still possible to climb down one after another. But the biggest problem is that there is no extra rope, after the first section, how to get the rope back, and then go down?

Why didn't you think about it for so much time last night? Liu Yong regretted it for a while, ate the food in his hand after a few times, and said, "Yun'er, can you go and bring me the kettle?" I'll sing a mountain song first. ”

Dong Yunqiao's face flushed slightly, handed over the handkerchief in her hand, and replied softly: "Here you are, big brother, wash your face and wipe your hands." This is the hidden word that the two agreed, and singing a mountain song means to relieve their hands.

In the early morning, there is a lot of dew on the bamboo leaves, and it is not a problem to wash your face and wipe your hands. Liu Yong thought as he rubbed it, how to use the existing rope. Originally, the best way was to fold the rope in half and hang it on the tree, and the person dragged the two strands of rope to slide underneath, so that any one of them could be pulled back to the whole rope, but this use could only slide to half the distance of the rope, do you have to pull the rope and jump a large distance? It's too dangerous, isn't it? Is there any way to untie the knot below? When Liu Yong was a veterinarian, he learned a variety of tethering techniques for tying and pouring cows, but there was no such knot.

"Yun'er, come out." Liu Yong scratched his ears and cheeks for a long time, but he had no choice but to call Dong Yun out.

Liu Yong explained his thoughts to Dong Yun in detail, frowned, and said, "If we can't get the rope back, we won't be able to get it down." Why don't we chop some bamboo? ”

Dong Yun looked at Liu Yong's sad face, and couldn't help but smile: "Big brother, don't be so troublesome." ”

Liu Yong was stunned for a moment, and said in amazement: "What, does Yun'er already have a way?" How do you untie the knots on it? How do you get the rope back? ”

Dong Yun saw that Liu Yong asked a few questions in one breath, obviously very anxious, and smiled secretly in her heart, and said, "You don't need to untie any knots." ”

Liu Yong was even more puzzled, "How can you make it if you don't untie the knot?" So far away. ”

"Big brother, I'm all set." Dong Yun raised his hand and stretched out the two pieces of rope in his hand. One is a long rope tied to a medicine hoe, and the other is a short rope that is untied into several strands and then joined together, which looks very long, but it is impossible to bear the weight of a person.

"What is this very thin rope for?" Liu Yong was even more puzzled.

"Big brother, look. I think so, I'll show you...... "Dong Yun first tied a thin rope on a small pebble, and then took a "Y" shaped branch from the ground, passed the string between the two thinner branches, and pulled it slowly, until the stone stuck to the gap and couldn't move, "After we followed the rope to the bottom......" Dong Yun let go of his hand, and the stone fell down because of gravity.

"I kind of get it. In this way, the rope can be untied. Liu Yong nodded, "It's just that as soon as we let go, the medicine hoe will be out of our control, what if we don't catch it?" Seeing Dong Yun's mouth move, obviously Cheng Zhu was in his chest, Liu Yong hurriedly said: "Yun'er don't say it yet, I'll think about it again." Dong Yun nodded slightly, and the smile on her face was even worse.

"How?" Liu Yong's mind was spinning sharply, and he suddenly saw another long piece of string. "I see!" Liu Yong patted his head, and his mouth suddenly opened, "Yun'er didn't take this string for us, but to catch the medicine hoe." ”

Dong Yun nodded with a smile: "That's right." ”

"This thin rope is attached to the thick rope at one end, and the other end is attached to the medicine hoe, and it becomes a ring. Yun'er, you're so smart. Dong Yun listened to Liu Yong's approval and smiled sweetly.

This method really worked, and the two of them slid down like this one by one, sometimes with a slight deviation from the trunk, Dong Yun could easily solve it with a hook of a bamboo pole. The two of them skated for a while and then took a break to check the strength of the rope. Fortunately, the rope has no friction and is almost not worn. When his feet stepped on the solid ground, Liu Yong's heart finally settled.

Dong Yun probed vigilantly for a while, and when she saw that there was no movement, she found a small stream, and the two of them cleaned it, identified the direction, and went to Fuyi.

"Can Yun'er recognize these drugs?" Liu Yong said some of the antibacterial and anti-inflammatory drugs he could think of, such as Huo Xiang, Dijin grass, Houttuynia cordata, dandelion, Sophora radix, large green leaves, plantain, Cnidium monnieri, Artemisia annua, and honeysuckle.

The two of them were collecting medicine while moving forward, and suddenly, Dong Yun stopped, pulled Liu Yong behind the rocks, took out a bow and crossbow, and whispered in Liu Yong's ear in a low voice: "Big brother be careful, I heard that there are people in the woods in front of me." ”
