The students were naturally happy and went to play separately, but Qin Hao and Li Gang were having a meeting in the office.
"His Majesty has promised that the college will recruit 100 new students next year. The college's infrastructure is fully equipped, but sir, it is not enough."
In a word, there is a shortage of teachers.
Li Gang looked at Qin Hao and Yun Ye playfully: "Is there really no one left in your sect?"
"Mr. Li, it's really just us." Yun Ye said bitterly.
"Well, in this case, it seems that we can only see if anyone sells my thin noodles." Li Gang stood up, and his originally skinny body turned out to be extremely tall at this moment.
"Then I'd like to thank Mr. Li." Qin Hao bowed slightly to Li Gang.
"I can find a master for this collection of classics and history, but for calculations and investigation of things, it only depends on the two of you."
Li Gang walked to the door and suddenly turned to Yun Ye and said: "Boy Yun, I will invite some friends to climb up Yushan Mountain tomorrow. I would like to trouble you to make some food and deliver it to the top of the mountain."
"The boy must keep the old gentlemen satisfied."
"Well, no one can refuse the food you made. By the way, if Mr. Qin has free time tomorrow, how about he climb up with us?"
"You must obey your orders."
After Li Gang left, Yun Ye suddenly said sourly: "Brother, do they look down on me a little too much? They beat me a few times at every turn, but they always treat you with courtesy. Why should you climb up to enjoy the scenery?
You make food."
"Then it's all up to you." Qin Hao scolded with a smile.
Yun Ye's face was full of confusion: "Why do you still rely on me?"
"Haven't you noticed that since you traveled through time and became smaller, your speech and behavior have become a bit childish? Now in the eyes of others, you are just a child. Have you ever seen any feudal patriarch talking to his children about human rights?"
Hearing what Qin Hao said, Yun Ye was dumbfounded. He actually pretended to be childish at first, which indeed brought him a lot of benefits. Niu Jinda and Cheng Yaojin regarded him as their nephew, and Li Shimin also regarded him as their nephew.
Treat them like seniors.
He didn't even realize it himself. He seemed to be pretending to be a child, or was it because he was affected by this body and even his thoughts became "younger"?
"Okay, don't think about it. We have even encountered wormhole travel. What else is impossible to happen?" Qin Hao saw Yun Ye's face full of confusion and patted him on the shoulder.
Yun Ye woke up suddenly and bowed deeply to Qin Hao: "Thank you, senior brother, for waking me up."
"Okay, it's been a tiring day today. You should go back early and prepare. We have to climb a mountain tomorrow morning."
The next day, Qin Hao got up early. Unexpectedly, Yun Ye was earlier than him. When he went out, Yun Ye had already arrived at the entrance of the academy in a carriage.
The two were about to go to Yushan. When Xue Er and the others heard the noise, they all clamored to go together. Although Li Shimin had spoken, they could continue to study in the academy, but they ran away from home and made such a big noise. It was inevitable that they would be attacked when they returned.
For punishment, it would be safer to hide in the academy.
"It's rare that you don't have to go to class, so why don't you sleep a little longer?" Qin Hao asked with a smile.
"Hey, I'm not used to hearing Mr. Niu's morning bell at this time every day." Xue Er and others looked at each other and smiled.
"Okay, let's go together then."
Xue Er and other students cheered and ran to the stables to get their horses. Yun Ye looked at the excited expressions of these children and couldn't help but look yearning.
"Brother, tell me, do they look like when we were in junior high school?"
Qin Hao smiled, said nothing, stepped on Chi Yue and jumped out from the side door. Xue Er and other students also chased after him on horseback with strange shouts.
Yun Ye got on the carriage with some sourness, reached out and patted Wangcai on the forehead, who was munching on young grass: "The riding skills are amazing, Wangcai, we don't have the same experience as them, so let's go slowly and piss them off."
"
Wangcai snorted and ran towards Yushan.
"Everyone is heartless. Run away. Run away. Without me, it depends on what you eat and drink!"
.......
At the foot of Yushan Mountain, several carriages were parked on the grass nearby. An old man with gray hair in Confucian robes said to Li Gang: "You old boy, you are an old man, but you want to drag us up to climb, and you are not afraid of falling."
Come anyway."
Li Gang laughed: "Li Shi and Yu Shan didn't say anything, but you, an old boy, talk a lot."
These old men have known each other for half their lives, and although they occasionally get into trouble over some minor issues, they have never been red-faced.
Mr. Yushan pointed at the mountain peak in front of him and laughed loudly: "I call myself Yushan. It is an elegant thing to climb this mountain today."
Mr. Yuan Zhang laughed and scolded: "Don't be too happy too early. This old boy brought us here for no reason. It is definitely not a good thing. We must ask for something when we are polite."
"You old guy is really getting more cunning as you get older!" Li Gang glared at the other party.
Mr. Li Shi, who had not spoken yet, also said with a smile: "I'm afraid it won't be a good feast today. If you don't tell me, I won't dare to go up the mountain with you."
"Are you still afraid that I will take out the ladder from the house and won't let you go down the mountain if you don't agree? It's a pity that this Jade Mountain is not a house, and I'm not that capable to trap you."
"Haha~~~"
While a few people were talking and laughing, a fierce sound of horse hooves roared over.
Li Gang secretly breathed a sigh of relief when he saw that the leader was Qin Hao.
Mr. Yuan Zhang on the side waited for Qin Hao and his entourage to dismount, and winked at the other two old friends and said, "Look, I'm just saying this old boy doesn't have any good intentions."
Qin Hao led Xue Er and others to Li Gang, saluted respectfully, and said in unison: "I have seen the mountain chief."
"Well, no need to be polite." Li Gang nodded with satisfaction.
Then he pulled Qin Hao to Mr. Yuan Zhang and the three of them, and introduced them solemnly.
"This is the Qin Hao I told you about. His courtesy name is Zihan. He has extremely high attainments in the way of studying things."
The three old gentlemen from Yuanzhang all looked at Li Gang with some surprise. This was the first time for them to see this old friend. He respected a young man so highly. This was obviously not to support the younger generation, but to introduce him to them as a peer.
Yuan Zhang looked at Qin Hao: "Oh? But one of you who presented the method of making salt and the auspicious potatoes?"
"Exactly." Li Gang caressed his long beard.
Qin Hao bowed to several older gentlemen and said, "Juniors have met all of you gentlemen."
"You're welcome, Zihan. Since you and Li Gang are the same generation, there is no need to be more polite." Mr. Li Shi said with a smile.
Yuan Zhang looked at Xue Er and the others with some curiosity: "Are these the disciples of your academy?"
Qin Hao nodded and waved to Xue Er and others: "I haven't met a few gentlemen yet."
"I have met you gentlemen." Xue Er and others bowed and saluted politely.
Li Shi and the three of them looked at each other and smiled, but did not say anything.
Yun Ye's carriage arrived late. Of course, it also had a lot of money. However, it seemed a little afraid of Chi Yue and never dared to approach. It only dared to follow Yun Ye's butt, and from time to time, it would poke its head out to peek at everyone. This way
The spiritual performance made several elderly gentlemen in Li Gang laugh.
"Now that everyone is here, let's go up the mountain!" Li Gang said to several old friends.
A group of people began to climb the mountain in a mighty manner.
Mountain roads in ancient times were not easy to walk. Even though Yushan was a battleground for military strategists in ancient times and the roads have been repaired, climbing up is still very tiring.
The few old gentlemen were out of breath soon. Fortunately, when they climbed to the mountainside, there was a pavilion, and everyone rested in the pavilion.
Li Shi saw that Xue Er, a young man like Xue Er, was neither blushing nor out of breath. He couldn't help but look at Li Gang curiously: "These students in your academy have good physical strength."
Li Gang said with a smile: "Our academy cannot teach lazy people who are not diligent in their limbs and don't know how to distinguish between grains and grains. They have to run and exercise every morning. There is a physical education class every two days, and they are trained by Niu Jinda."
"I see." Li Shi was slightly surprised when he heard this: "The academy still teaches military affairs?"
"Not only military skills, but also arithmetic, investigation of objects, and political affairs must be learned."
"Oh? Aren't you afraid of biting off more than you can chew?"
Li Gang did not answer directly, but turned to look at Qin Hao and motioned for him to answer.
Qin Hao did not excuse himself and said sternly: "Diversified courses are actually more conducive to stimulating students' brain potential. If they just memorize by rote, it will be difficult to have fun in reading. Therefore, when teaching in our academy, we often do not follow the textbook.
, but adopts a more concrete way to stimulate students' enthusiasm for learning, and interest is the best teacher."
"Interest is the best teacher?" Mr. Yushan heard this and praised: "This statement is quite unique."
Mr. Lishi, who had been silent until now, suddenly spoke: "What is the method of visualization you are talking about?"
Qin Hao thought for a while: "It's actually very simple. For example, what I'm going to talk about today is air pressure. In order to let students feel the air pressure more intuitively, I will prepare a small experiment in advance instead of telling the students what air pressure is.
, and then ask them to memorize a lot of weird and awkward formulas.”
"What is the air pressure you are talking about? Can you open the eyes of us old stubborns?"
Several old gentlemen looked at each other and all agreed with Mr. Li Shi's move. It was obvious that there was some comparison in it.
Qin Hao pondered for a moment, then suddenly walked up to Yun Ye and took out an egg, a wine pot, and a small casserole from the baggage he was carrying.
"You go and get some firewood, and then find some water and fill this casserole."
Seeing that Qin Hao was going to do those magical experiments again, Xue Er and others went to find firewood and water one by one.
Qin Haoyou took the egg and placed it on the mouth of the wine jug: "Gentlemen, this egg is larger than the mouth of the bottle. According to common sense, you cannot stuff the egg into the wine jug without damaging the egg, right?"
Li Shi and the other three looked at each other and nodded one after another.
Not long after, Xue Er and others arrived with a pile of firewood, and the small casserole was filled with mountain spring water.
Qin Hao walked out of the pavilion, made a simple shelf out of dead branches, then placed a small casserole filled with water on it, put the eggs in the casserole, and finally lit a fire and started boiling water.
The three old gentlemen were full of doubts about Qin Hao's actions and subconsciously looked at Li Gang.
Li Gang laughed, waved his hand and said, "Don't look at me, his knowledge is in a league of its own, and even an old man like me can't understand it."
After ten minutes, the water in the small casserole began to boil, and the eggs began to roll along with it.
After another two minutes, Qin Hao took out the hard-boiled eggs from the small casserole, then took out a piece of wood that was still burning from the fire. In front of everyone, he stuffed the wood into the empty wine pot and let it go.
Keep burning.
Except for Yun Ye, everyone present looked at Qin Hao intently, wanting to see what he was going to do.
"Please Mr. Lishi, help me peel off the shell of this egg."
Li Shi took the egg, which was still a little hot, and cracked the shell open, revealing a round and shiny egg in his palm.
Qin Hao took the egg, and then placed the egg on the mouth of the wine bottle while everyone looked at him with confusion.
But the egg was still too big. Only the tail was stuck in the wine bottle, and most of it was still exposed. Just when Xue Er and others thought Qin Hao's experiment was going to fail.
Suddenly, the egg squeaked and slid into the wine bottle.
"How can this be?"
"Here, how did the egg get in?"
Now it was not just Xue Er and the other students, but also the three old gentlemen Li Shi who looked dumbfounded.
Li Shi also deliberately took the jug in his hand and inspected it carefully several times. Only then did he confirm that the jug had not been tampered with and that the eggs inside were intact.
"What's the reason for this?" Li Shi asked, holding the wine bottle.
Xue Er and the others were scratching their heads: "Yes, sir, tell us what the principle is."
Qin Hao took the wine bottle and said seriously.
"This is the air pressure I just mentioned. You should all know that there is a breath of air between heaven and earth. If we cover our mouths and noses, we will die of breath in a short time. This kind of air is what we call air. Although the air looks like
It is invisible and intangible, but it actually exists, just like water. I told you about water pressure in class before. Similarly, air also has air pressure."
"The principle of this experiment is actually very simple. When firewood burns in the jug, the air inside heats up and the air pressure decreases, while the atmospheric pressure outside the egg remains unchanged. Under the influence of atmospheric pressure, the egg will be pushed into the jug.
.”
After this one-month course, Xue Er and other students have a relatively high degree of acceptance of the professional terminology mentioned by Qin Hao.
Li Shi and the others seemed to be listening to a book from heaven, but the facts were before their eyes. Although the three of them were older, they were not stubborn old men who would not change their ways. They also recognized in their hearts that Qin Hao had his own system of knowledge.
Li Gang couldn't help laughing when he saw his three old friends looking so enlightened.
"How about it? I'll just say that his knowledge is enough to be his own school, right?"
Mr. Li Shi laughed and scolded: "You old guy, you were sure early in the morning that you would see us fail."
"Don't talk nonsense. I don't have any. It's yourselves who want to test his knowledge. It's none of my business."
"You old scoundrel, you are so shameless."
"Oh, you were right. The old man's teeth are almost gone."
Xue Er and other students were secretly stunned. Is this really the stoic mountain leader in normal times?
