In fact, not only the students are looking forward to it, but the four people who teach are also full of curiosity.

Song Zhice has been very interested in this kind of thing since he was a child, and at this moment he muttered for a long time, suddenly raised his head, and said with some excitement:

"I kind of know the Dean's thinking."

After saying this, he looked at the other three with some pride, and then said:

"If I remember correctly, Gao Lu, a disciple of the famous Confucian Lu Zhi of the Eastern Han Dynasty, once said, take the chicken, remove its juice, light the wormwood fire, and in the empty egg, the wind will fly."

As soon as his words fell, Wei Wuya slapped his face and shouted:

"You say that, I seem to understand, Su Shi of the Northern Song Dynasty once recorded in "The Perception of Things" that the chicken opened a small trick, went yellow and white, entered the dew, and pasted it with oil paper, and dried it in the sun, it can be opened, three or four feet above the ground."

Hearing his words, Jiang Xinzhou and Liu Wushuang also patted their foreheads, and suddenly realized.

The so-called chicken, in fact, is an egg, Gao Lu and Su Shi's description is very simple, that is, knock an egg open, a small hole, pour out the juice inside, and then light the mugwort and put it in the eggshell, when the wind comes, lift it to the air, and the eggshell can fly away with the wind.

The mugwort here is actually an ordinary weed, which can produce a lot of heat and smoke after burning, so that the eggshell forms a low-pressure area and produces buoyancy, which is actually the basic principle of miniature hot air balloons.

At this moment, the faces of the four of them showed a look of excitement, although they didn't understand the truth of this, but obviously, a hint could be seen from these records, that is, Lin Ping'an's idea was completely possible.

"In the end, I have been instructed by the God of Medicine, the pattern is really big!"

Jiang Xingzhou sighed ashamedly:

"According to my guess, the dean's approach must be to enlarge the eggshell many times, maybe this way can carry people into the air, but the details of it, I can't think clearly."

"When the time comes, it will be clear to listen to the dean's explanation."

Liu Wushuang said with a smile: "You said that if you and I flew into the air when the moon was full, and raised a glass to invite the bright moon, what would it be like?" ”

Hearing this, some fascination appeared on the faces of the other three people, and it is no wonder that for ancient people, it was simply an unattainable thing to be able to fly into the air like birds, and now that it can be realized, anyone will be excited.

At the same time, many places in the capital were discussing Lin Ping'an's next class, even in the streets and alleys, because the students in the academy knew about it, and they all guessed in their minds what kind of magical thing it would be.

In the Wind Thunder Pavilion, Lei Zhen slapped the table and laughed.

"Good boy, if there is really that thing, then my Ming army will just stand in the air and throw down our thunderbolts at the Houjin Tartars, what do you think?"

His eyes were filled with excitement as he glared at the crowd in front of him and asked.

"It must be a crying father and a mother, people turn on their backs, and there is nowhere to escape!"

Saying this, everyone in the Wind and Thunder Pavilion laughed, and their minds began to imagine the scene when they stood in the air, throwing countless thunderbolts and thunderbolts at the Golden Tartar like a god, and they all jumped up with excitement.

In the middle of the night, Zhu Youxiao looked at the jumping candle flame in the bronze lamp and was stunned, and Wang Chengen stood beside him, with a trace of melancholy on his face.

In fact, he can't see his own prince clearly, he is only a teenager, but his demeanor looks like an adult, and the caution revealed in his words and deeds makes people feel a little distressed when he looks at it.

"It seems that being born in the emperor's family is really not a good thing!"

He sighed silently in his heart, probably able to understand why Zhu Youzhen was so precocious.

Zhu Youzhen's father, Zhu Changluo, was the crown prince in the Wanli period, but the prince's mother was only a palace maid in the palace of Empress Dowager Li, the biological mother of Emperor Wanli.

This matter is actually very accidental, when Emperor Wanli visited his mother, he had a whim for a while, and he was fortunate to have a palace maid, but he didn't expect this palace maid to be pregnant.

When the child was born, Emperor Wanli did not want to admit it, on the grounds that he did not leave a certificate after the palace maid was fortunate at that time, as was customary.

But under the insistence of the Empress Dowager Li and the proof of the emperor's living records, in the end he could only accept his eldest son.

Since he is the eldest son of the emperor, according to the etiquette of having no heir, he should be the future prince, but it has become a difficult thing to put on Zhu Changluo.

Because Emperor Wanli didn't like Zhu Changluo from beginning to end, what he liked was Zhu Changxun, the son of Zheng Guifei, and he wanted to make Zhu Changxun the crown prince.

So the Wanli Emperor and the Donglin Party on behalf of the Confucian etiquette law on this matter for more than 30 years of national dispute, and in this process, Zhu Changluo is like a leaf in the stormy waves, not only frightened, but also careful, even so, there was also a mallet attack in the three major cases of the Ming Dynasty.

This case is very interesting, it is said that a strong man with brain problems walked into the East Palace with a big wooden stick in his hand, and waved the big wooden stick in his hand and hit Zhu Changluo at that time.

There are a lot of strange things about this case, and a discerning person can see that someone instructed him to do it, but what is even more strange is that even if the three law divisions tried it, they couldn't find the mastermind behind it in the end, so they could only close the case hastily.

In fact, it's not that you can't find it, but you can't find it, because this matter has already involved Concubine Zheng Guifei, and if you dig it down, it is estimated that it will dig directly to Emperor Wanli's head.

All people are not stupid, and since they can't check it again, they have to stop it.

As the crown prince, Zhu Changluo can only smash his teeth and swallow his stomach, focusing on a forbearance word.

And Zhu Youzhen, who was only five years old at the time, was young, but he was not ignorant, he seemed to be able to feel the helplessness in his father's heart, and he also began to experience his father's caution.

So even now that he has become the king of letters, the caution that comes out of his bones is becoming more and more intense.

It's really helpless, the party competition in the Ming Dynasty is fierce, and if you are not careful, you will be involved, and the young Zhu Youzhen has long known the danger of this, so he can only choose to become a transparent prince, a prince who no one cares about.

"Lord Wang, you should rest."

Wang Chengen bowed and reminded carefully.

Zhu Youzhen snorted, moved his gaze from the jumping candle flame, looked at Wang Chengen, and asked very seriously:

"What do you think of Lin Ping'an?"

Wang Chengen also thought about it seriously, and then replied:

"Under the guidance of the god of medicine, he is naturally extraordinary, coupled with a calm personality and approachable personality, he can be a mentor and friend in private, and he can be the humerus of the Ming Dynasty in the public."

When he said this, Lin Ping'an's smiling appearance appeared in Wang Chengen's mind again, and he suddenly felt that the other party seemed to be somewhat similar to the king of faith in front of him, the only difference was that the former was thick-skinned and would definitely laugh when he should laugh, while the latter would never smile.

Hearing Wang Chengen's words, Zhu Youzhen was a little surprised, as if he didn't expect Wang Chengen to give Lin Ping'an such a high evaluation, and then he fell into contemplation again, and after a long time, he looked at Wang Chengen again and asked word by word:

"Wang Chengen, who do you say he will become in the end?"
