Although Leng Ye wanted to ask her how she wanted to get back into the field, Meng Xiaowan was obviously not too happy at this time.

didn't ask anything, just followed Meng Xiaowan and began to learn and practice.

Practicing until dusk, with the talent of the cold night, these few hours are just getting started, inspiring, and stepping into the subtle realm, which is already slow, but Meng Xiaowan is still quite satisfied.

Tell him that whenever he has time, he will come here to practice.

After going back, Meng Xiaowan was thinking about how to toss that gentleman, ahh

In fact, Meng Xiaowan had long wanted to buy something in the mall, but this was not the first time he had come to ancient times!

Many people, no, it should be said that the vast majority of people will not have this opportunity in their lifetime.

So Meng Xiaowan doesn't miss modern things so much, and has been experiencing antique things.

Another point, when she bought those modern things in the mall, she was really worried that Meng Weng would not accept them.

But now, there is not much to care about.

Meng Xiaowan bought a bottle of iodine solid in the mall that night, as well as concentrated ammonia.

She is not a partial student, almost every subject has similar grades, not to mention how good, but they are all middle to upper-class.

I don't believe I will lose to an ancient man who has not yet enlightened my senses!

The next morning, after breakfast, Mr. came, and Meng Xiaowan had already prepared an iron bowl and a feather!

It was placed on the gentleman's desk, and when the old gentleman saw this, he asked puzzledly, "What is this?" ”

"Bowl, feather, don't you know you?" Meng Xiaowan got up and asked.

Leng Ye swallowed his saliva, to be honest, Mr. was very face-saving yesterday, and he didn't know if Meng Xiaowan could do it.

If you can't succeed, it is estimated that you will be beaten today, and it may not be so light!

Then he'll have to be ready.

"What do you mean, you prepared these things?" The gentleman laughed. "What do you want?"

Meng Xiaowan's table contained iodine solids and concentrated ammonia, as well as small tools such as spoons and tweezers.

She bowed her hand first: "Sir, Xiaowan apologizes for yesterday's disrespectful ceremony!" ”

"It's okay, it's over!" The gentleman also replied generously.

Meng Xiaowan continued: "But sir, Xiaowan apologized for her own attitude, but I never thought that I was wrong in academic discussions. ”

"I prepared these for this evening, just to prove to my husband that it is useless to just read the Four Books and Five Classics."

When the gentleman heard this, he laughed: "The old man understands, you female doll just don't admit defeat, okay, the old man will give you this opportunity today to see what tricks you can make." ”

"Thank you, sir." Meng Xiaowan responded politely.

Leng Ye couldn't help but smile, he could also see that Meng Xiaowan had learned to be obedient after yesterday, and he was no longer short-tempered, but soft.

Anyway, there should be no less etiquette, and the gentleman has no excuse to be angry.

Meng Xiaowan walked over with those iodine solid things and asked, "Xiaowan dares to ask sir, how is gunpowder made?" What materials are needed? ”

"One nitrate, two sulfur and three charcoal, this is common sense." The gentleman replied.

Meng Xiaowan took out a grain of iodine from the bottle with tweezers and asked, "Does that gentleman recognize this thing?" ”

Mr. Tsai took a closer look, shook his head and said, "I don't know!" ”

Meng Xiaowan didn't tell him, but untied the cap of the bottle of concentrated ammonia and showed it to him: "Then do you know this?" ”

The gentleman approached and hurriedly covered his nose: "This ...... You...... You're a beautiful lady, how can you play with such pickled and filthy things? ”

Meng Xiaowan herself was actually quite disgusted, she smiled: "It's a little dirty, sir, this is the filth in the toilet, you're right." ”

"Xiaowan can make it explode today, comparable to gunpowder, I don't know if Mr. is credible?"

"Faith!" The gentleman pinched his nose. "If I believe you, I will read the books of the sages in vain, what a humiliation! Take it away! ”

"Pedantic!" Meng Xiaowan snorted at him, his hand didn't stop, he took two grains of iodine solid and put them in the bowl, and began to grind. "Sir, you, the so-called sages have read too much!"

"These things are dirty, but they are still valuable, not to mention, aren't those things in the toilet the best fertilizer?"

"You're unreasonable!" The gentleman was clearly angry. "How do you compare your husband to those illiterate farmer? The old man is also a showman! ”

"Huh! ~" Meng Xiaowan dragged out her tone. "The gentleman prides himself on being high, but he refuses to admit his failure! Don't change your mistakes! That's what humiliates Sven. ”

The gentleman was so angry that he began to tremble again: "Okay, Miss Meng, you get it!" If you can't figure it out today, see if I don't punish you severely! ”

"What if I succeed?" Meng Xiaowan asked him.

The gentleman pointed at her and said angrily: "If you succeed, the old man will recognize you as a gentleman!" ”

"Sir, it's hard to take it back!" Meng Xiaowan told him.

The gentleman pointed to the cold night: "This kid can testify!" ”

"Good! Deal! Meng Xiaowan said.

After grinding the iodine solid into powder, Meng Xiaowan scooped out the concentrated ammonia water from the bottle, poured it evenly on the iodine powder, and spread it flat.

Then he clapped his hands and said, "Then when it dries, it's time to witness the miracle!" ”

The gentleman sneered: "The old man can wait!" Such a child's trick, can Ann succeed? ”

Meng Xiaowan didn't speak, but Leng Ye looked at the bowl on the table intently.

"What are you looking at? Cold night, you don't think she'll succeed, do you? The gentleman said angrily. You're a good boy, read more sages, that's right! ”

Leng Ye wanted to say something, but he closed his mouth again.

He believed in Meng Xiaowan, but he didn't want to contradict Mr.

Meng Xiaowan smiled and winked at him, which meant waiting and seeing.

Leng Ye smiled and nodded.

The actions of these two children were seen by Mr., and he sighed deeply: "This little doll is ...... Only...... Alas! ”

"Poof." This pedantic gentleman really made Meng Xiaowan feel more and more funny.

After a while, I finally did it!

Meng Xiaowan took the feather, stayed away from it, and stretched the feather as far as possible.

Seeing that she is so cautious, she is cute, and Leng Ye likes and worries at the same time, and reminds her loudly: "Wanwan, if it will explode, be careful." ”

"Don't worry, it's small." Meng Xiaowan told him.

But after trying, she still didn't shoot it with a feather, eh, what to say, I suddenly remembered that when I played this little trick at school, it was because of her character of not being afraid of heaven and earth.

As a result, there was a bang, and my ears rang for a long time.

"How? Can't go on? The gentleman decided that she would not succeed and smiled happily!

Meng Xiaowan looked at Leng Ye in distress.

"What's wrong?" When Leng Ye asked this, he instantly understood, and hurriedly arched his hand and said: "Sir, Xiaowan is young, just playful, please don't punish Mr!" ”

"Punishment? Punish you big-headed ghost! Meng Xiaowan answered before Mr. You idiot, can you come and cover my ears for me? I was afraid of explosions, and I had tinnitus for a long time when I was a child! ”

Only then did Leng Ye react, Meng Xiaowan's eyes begging for help were not asking him to help beg for mercy.

"Whoa, here."

This nerd just passed, standing behind Meng Xiaowan, covering her ears with both hands.

"You...... You ...... "Mr. is really fast to the limit, after all, you can't hide the eyes of a person who wants to stab." "There is a way that men and women don't kiss, you kiss me and me like this, what kind of system do you become!"

Meng Xiaowan rolled her eyes, she didn't bother to pay attention to this old man, covering her ears was kissing me and me?

Is it possible to get pregnant if you hold a hand?

In short, someone helped cover his ears, it was much easier, Meng Xiaowan shook her little hand, and the feather hit it.

"Hmph, I won't ......"

Bang!

With a bang, a purple mist rose up!

Then it dispersed, and the gentleman's half sentence was stuck in his mouth, and he was only stunned.

"Oh no!" Meng Xiaowan jumped up. "I knew I was right!"

Not only Mr., but even Leng Ye was really stunned.

"Late, just a feather, how can it be so powerful?"

Meng Xiaowan clapped her hands: "I can't say that it has nothing to do with feathers, I can only say that it has nothing to do with it!" The key point is that iodine reacts with concentrated ammonia water to generate hexaammonia and triiodide nitrogen, which is insoluble in water, and after drying, the properties are extremely unstable, and the slightest touch will explode! ”

After listening to it in the cold night, I was stunned for a long time, and said in her tone: "I can't say that I didn't understand, I can only say that it is completely incomprehensible." ”

But this explosion also aroused Meng Weng's alarm, after all, it was not in the house, in an open place like the gazebo, the explosion was loud, and it could be heard more or less elsewhere.

"Sir!" Yu Chunfeng hurriedly ran over. "Did you hear anything just now?"

Meng Weng frowned: "I heard it!" Fast! Go check out the kids! It can't be those people who got it back, right? ”

Saying this, Yu Chunfeng was even more scared, and the two hurried to the pavilion.

But seeing such a scene, Meng Xiaowan sat on Mr. 's chair, his legs on the table, and Mr. bowed to her.

"Teacher Meng is on top, please bow to the students!"

After Meng Weng was shocked, he roared angrily: "Rebel girl! What are you doing here? ”

"Oops!" Yu Chunfeng clapped his hands and hurriedly went over to pull Mr. "You child, how can you let your husband salute you? That's disrespectful! ”

Meng Xiaowan hurriedly put her leg down and said, "He made a bet with me first, I won, and he was my student." ”

"I'm a college student, and it's not a big problem to teach an unenlightened ancient, right?"

"You!" Meng Weng was very angry, and turned around to find Mr.'s ring ruler.

Leng Ye's eyes were quick, and he hurriedly grabbed the ring ruler and threw it into the pool with lightning speed.

"Are you alright, sir? Sir, she's still a child, don't worry about her! Yu Chunfeng hurriedly coaxed Mr.

The gentleman only felt that he had been greatly insulted, and hurriedly ran out, waving his hand as he fled: "I can't teach it, I can't teach it!" Also, be smart! ”

"Huh!" Meng Xiaowan was not happy. "You're an adult, why can't you afford to lose? You told my parents where you lost! ”

The gentleman had to surrender, but he didn't stop. "Miss Meng is talented and intelligent, and stupid people like us can't reach it, so I will leave!"
