Naturally, the system would not really give Huo Changan a junior high school physics class, explaining that sound is a wave, and it is also divided into frequencies, what frequency is ultrasound......

"Mother, you can't do this method at your current level." The system poured cold water directly on the ground.

It is indeed impossible to do it, Huo Changan's current level is still in the Stone Age.

A machine that can produce ultrasonic waves, that is the invention of the electric age.

Huo Chang'an Nunu mouthed: "Okay...... But that method of putting food to attract is too low-level, right? ”

"It's not important to be low-level and high-level, just be useful." Evaluate systematically briefly.

Huo Changan shook his head: "It's useful, it's useful, but I can't use it, the food is too obvious, I want a way that I can't see or touch." ”

System: "......"

Can't see or touch?

Why don't you go to heaven?

Psychic is pretty much the same!

The system searched again: "Then this is left, the name of this substance Niangniang can't read it, but whether it can be read or not won't affect Niangniang's use——"

Huo Changan stared at the molecular formula: "What kind of ghost is this, gossip?" ”

"What gossip, that's benzene ring ......" the system cried bitterly......

How can the benzene ring be recognized as gossip?

How did good science become superstition?

One hexagon, one octagon!

This is clearly the molecular formula of this chemical substance, but unfortunately Huo Changan is really illiterate!

But the system doesn't want to give Huo Changan junior high school physics, and it also doesn't want Huo Changan to teach junior high school chemistry.

"Niangniang doesn't need to understand this ghost drawing, skip it, and just say what Niangniang is going to do." The system repaired the mood and opened its mouth low.

Huo Changan thought about it, she has completed three tasks so far, so she is still at the level of Stone Tool II, and she can exchange for two things.

In the previous Qixi begging competition, she used up one of the places to exchange cheese, and there was one left.

Huo Changan showed a determined smile this time: "I want to exchange the grass containing this thing." ”

……

Mrs. Liang is not the mother of the imperial concubine, but the aunt of the imperial concubine.

The Liang family was born in poverty, and the biological parents of the imperial concubine were the only daughter, and she died very early.

Therefore, the imperial concubine has been fostered in her uncle's aunt's house since she was a child.

It's a pity that my uncle's house is also a family with four walls, and it is difficult to continue.

So later, the palace maid was recruited, and the imperial concubine, who was still a little girl at the time, was sent.

I'm afraid that when I sent her to the palace that day, no one would have thought that she would later become the imperial concubine and become the most powerful woman in the Pingzhang Dynasty.

Today is Mrs. Liang's birthday, and the nobles in Beijing are all vying to celebrate her birthday.

Huo Changan got out of the carriage and was about to follow his mother in the direction where his daughter's dependents were, when his younger brother Huo Yanchuan stopped her.

"The matter of the post, although it has been found out, I still advise you to be careful." Huo Yanchuan whispered.

Early this morning, before going out, Huo Yanchuan told Huo Changan the news that he had just found out.

Huo Yanchuan naturally knew that telling Huo Changan on such an important day today would distract Huo Changan.

However, if you don't tell your sister and let your sister be vigilant, I'm afraid that it will be even more detrimental to my sister.

In case, if they take action, won't they trap my sister away?

"Watch out for whom?" Huo Changan asked.

"Watch out for the family." Huo Yanchuan replied.

Huo Changan was silent for a moment: "If it is not necessary, I will not act rashly." Today is for the Liang family, and everything on the side can be put aside for the time being. ”

Seeing that his sister understood in her heart, Huo Yanchuan stopped talking.

He told Huo Changan the result that he wanted Huo Changan to be vigilant, but he didn't want Huo Changan to be uncontrollable, so he would solve the matter today.

Killing two birds with one stone and killing two birds with one stone is not what Huo Changan is good at, I am afraid it is already outside Huo Changan's ability.

If it happens to be done one day, it will only be Huo Changan's luck.

Huo Yanchuan naturally didn't want his sister to take this risk and gamble on his luck.

The most important thing today is that it is naturally the Liang family.

It is the eldest brother Huo Yanping and the Liang family.

It's just that Huo Yanchuan thought that Huo Changan was to promote the relationship between his eldest brother and Liang Shenyu.

In fact, Huo Changan just wanted to stop it.

When he went out from Huo's Mansion, Huo Changan turned on the live broadcast and explained today's itinerary to the audience.

[What relatives hate the most]

[I can't afford to offend, I can't afford to offend, Miss Chang'an be careful]

[Ah, I saw my brother Chang'an again, so cute~]

[Good to my sister, Star Eyes~ I also want to have a brother like this...]

When Huo Changan saw the comment, his heart was dripping blood-

Dear, do you really want to have a brother like this?

I'll give it to you!

Now it's me who has a poisonous tongue, not you, of course it's cool for you to watch!

Try your poisonous tongue every day?

It's stressful!

[Huh? Isn't this green tea and pheasant?]

【Red Fire Trance】

[What, what kind of stalk is this, I'm new to popularize science! 】

As soon as Huo Changan sat down with his mother, he saw Shi Wanyue and Zhu Jinhan at the opposite table.

The family and the Ming school are incompatible, and the Liang family naturally will not put these two groups of people together.

Therefore, the left and right sides are lined up, facing each other from afar, and they do not offend each other.

Of course, it's just a superficial non-offense.

After the next banquet starts, I don't know how many moves and how many battles these two sides will have to fight openly and secretly.

Huo Changan saw someone in the comment area asking about the stalk of green tea and pheasant, and just wanted to explain, the enthusiastic old audience started talking.

This saved Huo Changan's effort, and Huo Changan immediately thanked the old audience for their support.

The old viewers also reminded the new children's shoes that they must go back to watch the record of the first live broadcast later.

Huo Changan was stunned for a moment.

A recording of the first live stream? Can you still watch it back?

It's so advanced!

You can see not only the things of the present, but also the things of the past.

It is worthy of something from the future, if there is such a thing now, the historians will be relaxed, and it would be good to directly point that lens at the emperor.

When the time comes, you can look back at which section you want to look back, and it is very detailed and vivid.

But there is one bad thing, that is, if the emperor wants to tamper with it, will it be particularly troublesome?

The transcript is scribbled out and rewritten.

This—

How do you fake it?

Huo Changan was still in a hurry at this time, and the Jin family stepped on iQue's daughter under the table.

Huo Changan almost didn't cry out "ouch", and glanced at his mother sadly-

Mother, this is mother!

Then, Huo Changan looked up and saw that Shi Wanyue had already gone to greet Liang Shenyu.

Huo Changan finally understood what his mother meant, and he disliked himself for being slower than Shi Wanyue!

But Shi Wanyue's hypocrisy, she hasn't learned it for so many years......

Huo Changan had no choice but to tug at the corners of his mouth, adjust his expression and demeanor, and walked towards Shi Wanyue, who was talking to Liang Shenyu-

The quest pack seems to have a task called sowing discord?

Do you want to give it a try?
