"Objects are composed of molecules, atoms, and ions, and the molecules of all substances are in constant motion, and they are in irregular motion, and the movement of molecules is related to temperature, the higher the temperature of the object, the faster the movement of molecules...... This irregular motion is called Brownian motion...... The phenomenon of diffusion is the proof that the molecular motion of matter never ceases to move in random motion......"

Baili Qingfeng sat in the classroom and listened to the lecture, which was a lesson on molecular thermal motion, and this class was followed by a lesson on the interaction between molecules.

Baili Qingfeng had already flipped through these books when he was studying on his own, but the effect from the mouth of Professor Huang was naturally different.

As a professor at Shire University, there is no doubt about the level of these people, although because of the difference in the times, the amount of knowledge reserve of these people is estimated to be about the same as that of the relevant professional college students in his previous life.

It's like Professor Zhou before.

The resonance course he told him benefited him a lot, and coupled with a kind of sound attack method he practiced, the combination of the two has derived a new secret technique.

This secret technique not only has the characteristics of the sound attack of the thunder and roaring technique, but also contains the vibration damage to the human organs caused by the principle of wave frequency resonance.

Baili Qingfeng has decided to rename this exercise, which is called Fluctuating Thunder Sound.

"The only question is, how do I take a leave of absence next......

Baili Qingfeng had a headache.

Four or five o'clock this afternoon is the time for the opening of the Caveman World Passage.

The opening cycle of the cave man's passage is nineteen days, and it will take him at least nineteen days to go, this leave, it is not easy to ask, and he doesn't particularly want to ask for it......

But if you don't invite it, you can't.

On the one hand, he didn't have enough funds, so he had to go to the Caveman World to brush up some Chenjin to sell it as research and development funds for the World Peace Committee, and on the other hand, the Blood of the Brave had a medicinal herb that could only be obtained in the Caveman tribe......

The morning passed quickly in a trance.

After class, Baili Qingfeng was about to go to the cafeteria to eat, but the mobile phone rang, and his father Bailihong's voice came from inside: "Qingfeng, is class over?"

"Class is over. ”

"Then come back early for a meal. ”

"Good. ”

Baili Qingfeng responded.

I turned around and walked out of the school gate, and was about to go to the bus stop when a voice came from a distance.

"Blue Point. ”

Baili Qingfeng followed the prestige, and saw the pure and lovely Shi Yiyi, who was wearing a white dress, standing on the side of the road, attracting frequent sideways glances from the students of Charles University.

"Why are you here?"

"I'm waiting for you. ”

Shi Yiyi smiled and said, "I'm here by car, are you going home, I'll give you a ride." ”

"Oh, good. ”

Baili Qingfeng thought for a while, agreed, got into the car, and fastened his seat belt as soon as possible.

"Qingfeng, it seems that you haven't bought clothes for a while, you have been changing back and forth between these two or three sets, I bought you a set of clothes, you see if you like it or not. ”

"Clothes, what are you buying clothes for? There are three sets of clothes that are completely enough, one for wearing, one for washing, and one for spare, we are not in those countries of the Aurora Empire, Xia almost does not have a temperature below ten degrees, and the clothes can basically be dried on the same day after washing. ”

Baili Qingfeng felt a little strange.

Isn't it a waste to buy so many clothes?

"Just look at it, whether you like the style or not. ”

Shi Yiyi's tone said with a hint of coquettishness.

"It doesn't matter if you like it or not, it's just the clothes. ”

Baili Qingfeng said, still a little puzzled: "Why did you give me clothes for some reason?"

Shi Yiyi glanced at him: "You don't know about your birthday today?"

"I know, but isn't it just a birthday, just eat an egg, why do you have to buy clothes?"

“......”

Shi Yiyi felt a little tired.

But......

I endure!

"It's your twentieth birthday, and it's very significant, and it's not the same as the previous ones. ”

Baili Qingfeng thought about it, twenty years old, and then continue to grow, the next big ladder is thirty years old, in other words, he is already a person who runs three, and it is indeed a little different.

"Alas...... Not young anymore. ”

Baili Qingfeng felt some emotion in his heart.

But he really doesn't have any feelings about clothes, if Shi Yiyi really plans to give him a birthday gift, it is better to give him a lighter, he has encountered several times the embarrassing situation of not having a lighter when he wants to cremate someone.

The vehicle carrying Baili Qingfeng quickly returned home.

The house is really lively.

In addition to Baili Hong, Baili Butterfly, who worked in the Nanshan Dry Rest House, also returned, and there were many people who remained in Baili Changkong, Baili Tianxing, Baili Huang, Baili Ji, Baili Lian, Baili Ruoshui, and Baili Ruoxue.

Not long after Baili Qingfeng came back, Ge Wen, Ge Bai, Ge Feilong, Ge Shuren and others also rushed over with their juniors to celebrate Baili Qingfeng's birthday.

For a while, the courtyard, which was not very large, was almost full.

This scene made Baili Qingfeng a little speechless.

Isn't it just a birthday?

Why are so many people running here?

How did he spend his birthday the year before last?

Baili Die boiled him an egg, and Baili Hong gave him another ten yuan of pocket money.

How did he spend his birthday last year?

Or Baili Die boiled an egg for him, and since he had already worked on summer vacation, he didn't give him any pocket money.

This year......

It's just that so many people come, gifts, cakes, everything.

"This time, my sister is busy in the kitchen. ”

Baili Qingfeng muttered in his heart.

Fortunately, Baili Lian and Baili Ruoshui all went to the kitchen to help, and it was not Baili Die who cooked alone, which slightly reduced his pressure.

"Qingfeng, I can cook too, so let's go to the kitchen and help out. ”

Shi Yiyi said after returning with Baili Qingfeng.

"No, you are a guest, how can there be a reason to let guests do things. ”

"Yiyi girl has recently learned two crafts, and if she wants to go to Qingfeng, you can let her go. ”

In the hall, it was like another master's hundred miles of sky and said with a smile.

The generation of Baili Qingfeng's grandparents did not live long and died early, and the biggest generation at present is Baili Changkong, and naturally no one in the audience refuted his words.

The arrival of the guests on both sides of the parents in the courtyard was only the beginning, and as the time approached twelve o'clock, waves of guests came to visit.

Lu Ping, Hong Tiange, Chifeng, Ma Hua, Mo Qi, Si Wei, and Ye Fusheng, one by one, like flowing water seats, arrived one after another.

It's just that although Baili Qingfeng's house is a small two-story building, but the place is too small to stretch out, these people did not stay after coming to eat lunch, gave gifts, congratulated, and left quickly, and everyone stayed for no more than ten minutes.

But even so, looking at the endless stream of visitors, Bailihong still has a sense of eye-opening.

He also knew more or less that Baili Changkong had summoned the previous old brothers to establish a Thunder Sect, and he was quite powerful in the Char area, but after all, he was not a person in the martial arts circle, except that he felt that the business was very easy to do and the money was easy to make, he did not have any intuitive feelings.

But at this moment......

Seeing that one after another big people with extraordinary identities came to visit and congratulate a junior like Baili Qingfeng on his birthday, even if he was slow to react, he could think of how great the influence of the so-called Thunder Sect in Baili Changkong had reached at this moment, and the business in his factory suddenly became smooth sailing, nine times out of ten, it was also the Thunder Sect secretly making efforts.

"It seems that the Baili family is really going to be developed. ”

Ge Xiu looked at these guests who kept coming to the door, and his expression was full of emotion.

"The Thunder Sect Sect Master is a hundred miles into the sky, the deputy sect master is a hundred miles of Qingfeng, and below is the elders, but how can the weight of the elders be comparable to the two sect masters, in other words, this Thunder Sect is almost equal to the private power of the Baili family, and now that the Hundred Miles Qingfeng is celebrating his twentieth birthday, Char, and even the people with status in the Xia Haitian realm who dare not appreciate their faces? Even some ordinary people may not be qualified to step into the gate of the Baili family......"

Kazuki has always been very sensitive to politics.

At the end, he also took a look at the somewhat dilapidated gate of Baili Qingfeng's house.

Albeit......

This door, this courtyard, and this building are just ordinary people in Wuhe City, but as the saying goes, no one asks about the poor in the downtown area, and the rich have distant relatives in the mountains.

With the current weight of the Baili family, even if they live in a small grass hut, there will still be an endless stream of visitors.

At this time, another group of people walked in outside.

Donald and Lady Yuri are all in it.

And the first of them......

It's none other than Naber, who has just become the speaker of the Hahai Prefecture Local Assembly in this election.

The Speaker of the Local Council of the Kingdom of Chia has unparalleled power, and the positions of governor, treasurer, and education chief are all appointed by the council after the meeting, and the speaker of the local council is undoubtedly equivalent to the number one in Xiahai Prefecture.

The arrival of Speaker Naber caused quite a stir in the crowd, and anyone with a little common sense knew the weight of this speaker.

But even if the speaker came in person, he was on an equal footing with Baili Qingfeng and Baili Changkong, especially for Baili Qingfeng, who was even more enthusiastic.

Because he knew that he was able to easily win the position of speaker from the people supported by the third prince and the sixth prince, and Baili Qingfeng was a great contributor to defeating the Qilin Sword Sect in a battle.

"Thunder Sect...... Is the influence already so great? Baili Qingfeng celebrates the birthday of a junior, and the speaker actually comes in person......

Heidi, who was next to Ge Shuren, turned a little pale.

As a person in the system, I deeply understand the weight of the speaker of the parliament.

Ge Shuren didn't speak, he glanced at Ge Feilong, who was following Baili Qingfeng's side like a little guy to help on his own, and then at Ge Shasha, who was like a beautiful girl beside him, and instantly made a decision in his heart: "Sasha, Qingfeng also said before, I am willing to guide you to practice, from tomorrow, you will practice martial arts with Feibai every morning, follow Qingfeng to practice martial arts, in addition to practicing martial arts, remember to have a good relationship with Qingfeng, be flexible, I believe that with your intelligence, you will soon be able to surpass Feibai." ”

"I know, Dad. ”

Ge Shasha nodded.

......

A birthday celebration was lively for several hours, and as Baili Qingfeng's class time was approaching, it had to end early.

Considering that the world of cave people was about to open, Baili Qingfeng, who had never thought of a reason for taking leave, hesitated for a moment, and finally found Baili Changkong, who was still sending off guests.

He planned to confess the matter and let Baili Changkong ask for leave for him.
