Laws are common in many worlds. Brother Ha talked about a bunch of things from the textbooks of his previous life, which can also be corresponded to in this world.

The people in the audience asked all kinds of questions, and Ha Ge tried to answer them from the perspective of mathematics, physics and chemistry.

"Teacher Ha, according to what you said, lightning striking water can produce hydrogen and oxygen, and the combination of hydrogen and oxygen can produce flames, so can it be concluded that monks with thunder and water attributes can use fire path techniques. ”

"Theoretically, yes, and it's quite powerful," Hago nodded.

"Mr. Ha, the refractive index of water is 1.33, so if you fight in water, will it cause pollution?"

"No," Hago shook his head: "The refractive index occurs between two different media, and there is no refraction in the same medium." ”

"In the case of wind, the wind direction and speed must be considered, otherwise it is easy to produce a little worse. ”

"That's right" Ha Ge thought for a moment and said cautiously, "But in the case of a fast attack, the low-speed wind is negligible. ”

……

Everyone's enthusiasm was completely mobilized, asking questions together, thinking about problems together, answering questions together, and unconsciously, Ha Ge gradually combined the theory of the previous life with the current Dao system, and improved a lot of Dao techniques.

At this time, Brother Ha suddenly realized that he had discovered a new theoretical framework of Taoism, and in the morning, Brother Ha's understanding of Taoism was much deeper than in the previous month.

The speed of Jiang Daoqi's record is extremely fast, not only the theory explained by Brother Ha, but also the questions and answers raised by everyone, the content is very large, and I am afraid that it will cause a sensation in the whole society.

In fact, many junior high school theorems are closely related to daily life, but no one in this world summarizes them. Brother Ha broke this layer of window paper, and Jiang Jia'an and the others all had a feeling of sudden enlightenment.

Reiki is also a kind of energy, but according to the wood, fire, earth, gold, water, wind, thunder and the corresponding attributes, its essence is no different from plants, flames, soil, metal, flowing water, wind, thunder and lightning, so the theory of the previous life is completely applicable.

"Bang", there was a sudden abnormal noise in the classroom, and Zhang Panpan's whole person fell into a state of obsession.

"What's wrong?", Song Xiaoqi, who was sitting next to her, was surprised and overwhelmed when she found Zhang Panpan's abnormality.

"Breakthrough, foundation building period", Jiang Daoqi, who was recording, stopped the ink pen in his hand and said with great certainty.

"Huh" Brother Ha's hanging heart followed down, since he came to Kyoto, the land of water, Zhang Panpan has not lacked Qi Cultivation Pill, for breaking through to the foundation building period, what is lacking is only a perception.

Now that Brother Ha has told a brand-new Taoist theory, the doubts that plagued Zhang Panpan's mind have been completely solved, and it is also very logical to step into the foundation building.

Brother Ha knew that building a foundation was a process, and it needed aura to penetrate the limbs and bones of the whole body, and it was not suitable to be disturbed, so Brother Ha hurriedly ended the morning class and returned to Hafu with Zhang Panpan.

Within two days, Zhang Panpan had already broken through to the foundation building period, which was much easier than Brother Ha at that time.

Ha Ge returned to the classroom, this time in a large classroom, and there were many familiar and strange people in it.

"What's going on?" Brother and Zhang, the second monk, were confused, they taught the students by themselves, and it was understandable for some young people to come, but what did this group of uncles and aunts do.

As if seeing Brother Ha's question, Jiang Daoqi said with a smile: "Teacher Ha, these are some of the senior generals of the Water Country, after reading your handouts, they expressed that they want to take advantage of their leisure time to take classes. ”

"Oh", now that Brother Ha already knew their identities, a faint smile appeared on his face: "It's an honor." ”

"But," Brother Ha's tone changed, and he said a little helplessly: "In such a large classroom, I am afraid it will be very hard for me to speak with aura......"

"Master, don't worry" Zheng Chengxiu ran over directly and handed Ha Ge an iron horn barrel.

"This is a megaphone" Brother Ha's eyes widened instantly, he just mentioned it casually in the last class, did Zheng Chengxiu make it?

"Master, can you try it well?" Zheng Chengxiu said like a treasure: "In order to make this megaphone, I have been studying alchemy hard for the past few days, and I don't know that I am so talented if I don't work hard." ”

"Hehe" Brother Ha smiled and said nothing, directly held the megaphone, and tried his voice twice: "Hey~Hey......"

In an instant, everyone in the audience subconsciously turned their heads sideways and covered their ears with their hands.

"How can such a simple device suddenly amplify the sound?

"Zheng Chengxiu has really changed her mind, no wonder Mrs. Zheng is smiling from ear to ear when she sees everyone"

"It's amazing, the Holy Hand of the Bad Disciple really lives up to its reputation, it seems that my stinky boy has also been saved"

"Ahem" Someone coughed lightly twice and raised his hand to signal: "Zheng Chengxiu Shaoxia, your megaphone is not for sale, we will shout to the soldiers, it should be good to use this." ”

"Yes", everyone suddenly realized, in the occasion that you need to speak loudly, this little thing is very useful.

"And me," a loud voice shouted, "I need the biggest megaphone, and I can sweep the battlefield with my sonic skills alone." ”

"Okay, good, no problem" Zheng Chengxiu hurriedly agreed, business is booming, and the wealth is rolling.

"Nephew Cheng Xiuxian, are you interested in joining the Elite Club?", an enthusiastic voice came, attracting the attention of many people.

The voice turned out to be Qin Muyang!

Zheng Chengxiu blinked his eyes, a little unable to believe his ears. As a representative of the scum, he has already been ordered to kill by the elite, what is going on today?

Seeing that Zheng Chengxiu hadn't reacted yet, Qin Muyang continued to increase: "It's also okay to join the Elite Academy, which is also what Old Lady Zheng meant at the beginning." ”

"I'm lost" Brother Ha was dumbfounded, Qin Muyang is too shameless and skinless, he was the one who resolutely didn't want Zheng Chengxiu some time ago, and now he is the one who took the initiative to invite Zheng Chengxiu.

"No" Zheng Chengxiu shook his head and said very calmly: "I have joined Erhamen, and I think Erhamen will be much better than the elite." ”

"Hmm" Many people present nodded in agreement, with the handouts that were circulated in Brother Ha's last class, coupled with Zheng Chengxiu's current progress, it can also prove that Erhamen is extraordinary.

What's more, is Zheng Chengxiu, who has broken away from Erhamen, still Zheng Chengxiu?
