On the official road to the south of Huainan Road, a group of fiery red horses carried a young man in brocade clothes, accompanied by several guards from the Great Yao Garden, talking and laughing along the way, heading south.
Who is this group of people if it's not Xu Yunyan and the bodyguard who must protect Xu Yunyan no matter what?
While these guards were guarding Xu Yunyan all the way south, and they were discussing whether the south would be hotter in this midsummer season, Xu Yunyan looked at them and said with a smile.
"When it's cold in the north, many places in the south are warmer than the north. You just think that when it's hot in the south, it's hotter than the north. There's no such truth."
After Xu Yunyan suddenly said these words, the several guards in front of him looked at each other.
Isn't it like the sun is far away? When several people murmured like this, Xu Yunyan couldn't help but think of the story they told about the distance between the two suns.
Isn't this the story of "Two Children Debating the Sun"? Just when Wu Xu Yunyan was thinking this, he saw that the guards in front of him didn't believe what he said at all, and then smiled at them and said.
"There are many things in this world that are not what we think. Just like if you throw two rocks, one large and one small, from a height at the same time, which one hits the ground first may be beyond your imagination."
Xu Yunyan was going to give them some popular science, but when these guards heard this, they said it with dissatisfaction.
"Is there any need to think about this? The big stone must have fallen to the ground first, otherwise the small stone could have fallen to the ground first?"
Everyone here looked at Xu Yunyan in confusion, and Xu Yunyan looked at them and smiled.
"You guys, your careless arguments like this every day are just bold nonsense. I really admire you. You can find a high place in front of you and try it on it. Two stones, one big and one small, will definitely fall to the ground at the same time. ah!"
Xu Yunyan's words made the people in front of him a little unable to react. You looked at me and I looked at you, asking each other.
"How is this possible? Big rocks must be heavier than small rocks. We still know a little bit about this. Big rocks must fall to the ground faster than small rocks."
Xu Yunyan smiled and spoke slowly while looking at the younger brothers who didn't believe what he said.
"Wouldn't you know if what I said is right or not if you try it?"
Xu Yunyan successfully changed the topic at hand from the temperature difference between the north and the south and the distance of the sun to a small experiment that could be easily implemented. Xu Yunyan and everyone in front of him were proud of themselves and admired their brains.
The group of guards in front of them were just as Xu Yunyan thought. They came to the woods in front of them and took a rest.
A guard who was skeptical about what Xu Yunyan said immediately went out to find two stones, one large and one small.
The big one is as big as a fist, and the small one is only as big as a thumb. He is holding these two stones here and asking.
"General, do these two stones prove what you say?"
Xu Yunyan nodded, "Yes, don't you still believe me, General? Will I still lie to you, General?"
When Xu Yunyan said this, this group of people looked at each other in confusion.
"It's not that we don't believe the general, but it's just that this is too fantasy, isn't it?"
Just after they said this, Xu Yunyan stepped aside.
"Okay, let's go up a tree to illustrate the problem."
Suddenly, Xu Yunyan looked at the soldiers in front of him and had a sense of déjà vu that made him climb a tree.
A soldier volunteered to climb this tree, but the temperature in this southern city was somewhat suitable, and the branches and leaves were so lush that there were thorns from bottom to top, so he had no chance to climb.
The soldier was embarrassed here, and Xu Yunyan couldn't help but cough again to attract everyone's attention.
"You can't climb this tree. Can't you climb the slightly upright tree trunk next to it?"
When Xu Yunyan said this, he didn't pay attention to what the tree next to him was, and asked his soldiers to climb up. The soldiers hurriedly nodded to Xu Yunyan.
"That's what the general said. We almost got into trouble."
Everyone saw just one soldier saying this, and when they hurriedly stepped forward and started to climb toward the tree that was easier to climb, they suddenly heard a loud shout.
"Where did this thief come from and dare to come into my woods and steal my fruits?"
This suddenly startled everyone, and they hurriedly looked towards the place where the sound came from. A tough old farmer-like man rushed out with a pitchfork, pointing at the tree and the place below. A group of people kept roaring here.
"What do you do? Why do you come here to steal my fruit?"
"Your fruit?"
Everyone looked up at the tree and found no fruit on the tree.
"Sir, are you mistaken?"
After a soldier asked this question, the farmer in front of him suddenly laughed.
"You are very nice to talk to. You are indeed a learned man. You open your mouth and still call me husband. This is not something you can call me casually. This is a title for people who can study and educate people or make apprentices in all walks of life."
However, Xu Yunyan and his soldiers did not pay attention to these details. Instead, they asked him.
"Sir, this tree is empty, and there is no fruit. How come we want to steal this gentleman's fruit?"
All of a sudden, the old farmer was even more proud of himself.
"So that you may know, there is a hole in the middle of the tree. I put some fruits in it and wanted the monkeys nearby to make monkey wine for me."
"What? Monkey wine?"
Xu Yunyan was shocked.
"Hou'er Brewing is a legendary wine. Are you cultivating yourself here and becoming an immortal?"
After Xu Yunyan said this, the old farmer immediately put down the fork in his hand while holding his beard and said with a smile.
"I didn't expect this young master to be knowledgeable and know about monkey wine."
"I know."
Xu Yunyan said here hurriedly, and then waved his hand.
"What are you still doing up there? If you don't hurry up and come down, our nonsense will almost ruin this gentleman's important event."
Xu Yunyan waved like this, and the soldier who was about to climb to the top of the tree was a little unhappy.
"General, I haven't tested which stone will fall to the ground first."
This sentence shocked the old man in front of him.
"Are you a general of the Tang Army?"
But when he just said this, Xu Yunyan spread his hands and looked like he was whining.
"Passing by, we are just passing by. Don't worry about these details. Just throw the stone down from where you are."
Xu Yunyan had just been polite to the old man, then turned around and said to the soldiers who were ready somewhere on the tree, and the soldiers lived up to expectations.
"Master Protector, just keep an eye on me."
As the soldier spoke, he threw two stones, one large and one small, out of his hand at the same time.
Then a miraculous scene happened.
The two stones actually fell to the ground at the same time.
"How can this be?"
All the soldiers stared at each other, and the guy who had witnessed the whole process who wanted to make monkey wine even lost his faith.
He wiped his eyes and asked doubtfully.
"I haven't seen it, have I? How is this possible? Could it be that this person is also a master of Taoism? If so, I wonder if we can learn from each other?"
However, the person in front of him wanted to compete with Xu Yunyan, but the group of guards in front of him were frightened and they hurriedly gathered around Xu Yunyan.
"What do you mean? You want to compete with my Protector-General. What do you do? My Protector-General is..."
Before these soldiers could finish speaking, the people in front of them looked at Xu Yunyan in surprise.
"You soldier, you are so attentive in guarding me. I just want to ask you for advice on Taoism and see what you look like as a soldier. If I continue talking, I will have the urge to chop me with a knife."
Xu Yunyan shook his head.
"It's not that we are here to maintain our identity and do not conform to what the hermit master said, but we are really powerless against the Taoism you mentioned. We just happened to know such a thing."
Xu Yunyan just said this and hurriedly prepared to say goodbye and leave, but the man in front of him stopped Xu Yunyan with a smile.
"General, don't be so hasty."
This time the guards were even more frightened.
"What do you want to do? This is the Protector of the Anbei Protectorate, the Champion General, and the Champion Marquis. If you dare to mess around again, be careful that the swords in our hands are not ruthless."
One person directly said Xu Yunyan's name, which made the people in front of him even more stunned.
"It turns out that the general is the famous champion. It's disrespectful."
But he seemed to have thought of something and said, "General, wait a moment."
As he spoke, he climbed up the tree like an ape and took out a small bottle of liquid from the tree. When he came down, he held it to Xu Yunyan with both hands.
"The Champion has always been an awe-inspiring existence, but his life is short-lived. There is a bottle of fine wine here, please take the Champion with you."
Xu Yunyan looked at the jade-like bottle that was about the size of her mother's finger and couldn't help but be curious.
"What is this Taoist priest?"
At this time, Xu Yunyan didn't say anything to him at all, but instead called him Taoist Master. This also made the people in front of him not dissatisfied. Instead, they looked at Xu Yunyan talking here.
"A little respect, I also admire the champion's style, but how should I put it? The champion since ancient times, hey!"
At this point I could only sigh helplessly.
Although he didn't finish speaking, everyone's hearts twitched. He might have meant that champions have been short-lived ghosts since ancient times, right?
Xu Yunyan looked at the man in front of him who looked like a Taoist master who was looking forward to taking the bottle of liquid, and he stepped forward and clasped his fists.
"Then I have the audacity to accept such a precious treasure. I wonder if the Immortal Chief can tell me his name? So that I can provide the Immortal Chief with some help within my ability."
The person in front of him smiled and shook his head.
"I'm just a wandering doctor. By chance, I saw monkey wine here and stayed next to it. I want to taste it every year. But I almost offended the general just now. I hope the general can atone for his sins. ! This is just an apology. General, please remember that drinking this bottle of liquid will definitely save your life when your life is at stake, so you must wear it with you."
Xu Yunyan put it into his arms with great care and bowed to the old man in front of him.
"Thank you very much, elder. I don't dare to say goodbye to the gift given by the elder. I just want to keep the elder's surname and name, so that I can report back to you in the future."
Xu Yunyan said this, but the old man in front of him shook his head.
"Why do you have to be like this? People in the mountains and outsiders don't like this. As long as the champion will spare no effort for me, Datang, I will be satisfied."
The old man said this, took a few steps back, turned around in the woods, and began to move quickly.
Soon, the figure was no longer visible.
Seeing the person leaving, Xu Yunyan was a little confused.
"Is there such a highly respected person?"
But when Xu Yunyan was thinking this, he took out the small jade bottle in his arms. It looked like a piece of jade, and it would be nice to tie it around your waist and make a jade pendant. There was still a little liquid flowing there, which was even more satisfying. Xu Yunyan looked at it and felt that this was no ordinary thing.
Did he meet someone like a Qi Practitioner?
Xu Yunyan muttered like this, but quickly shook his head.
Believe in science.
