Long Yuyan smiled evilly, his eyes seemed to be looking at the child who was playing tricks on candy, and sighed in his heart, Xiao Tianmo was like a creeping little tiger, he still had to follow the hair. rubbed twice on the seat, slowly approached Xiao Tianmo, and draped Daao in half on him.

Xiao Tianmo paid attention to her movements, snorted coldly, and ignored it, but his face was a little better. Pretending, Long Yuyan had a burst of amusement in his heart.

"Okay, don't be tantrummer, wear so little, the water is so cold in autumn, put it on." Long Yuyan pulled the big ao on Xiao Tianmo's body up.

"This king heard that you made a bet with the daughter of the Su family, and if you lose, you will waste your hands? Self-disfiguring? Xiao Tianmo gritted his teeth, when he heard this, he was almost angry, although he felt that she would not suffer, but he was still very worried about this stupid woman! This damn woman didn't know it, and until now she still looks light.

"Ah, that's what you say." Long Yuyan couldn't help laughing, and sure enough, Xiao Tianmo's face was even darker, she thought that this kid was angry about something, and the co-authoring was for this matter.

"When you make a bet, you are sure that you will win."

"Nope."

"You!" Xiao Tianmo didn't look over, when he saw this stupid woman again, he was afraid that he would really be unable to help but strangle her, and he dared to make such a bet without being sure, he was really too indulgent to her.

Xiao Tianmo was angry, Long Yuyan shrugged indifferently, what if she lost, she wouldn't really cut off her hands, let alone scratch her face, she was very fond of her appearance, although inner beauty is very important, but now the society that looks at faces is very realistic.

Take 10,000 steps back and say, even if she is unlucky and really doesn't play, she loses the bet. She still has a portable amnestic device in her hand, so she really can't use group amnestics, although it will take a little effort but the effect is good.

"Okay, don't be angry, listen to me tell you, the piano is called Shen Bi, Miss Su guessed it as soon as she described it, although I haven't seen it, but I have seen the relevant description in ancient books before, there is a professor, ah, no, a knowledgeable person from outside the world has also done Shen Bi's relevant explanation, Miss Su thought it was a dumb piano, but in fact, the piano was not dumb."

Xiao Tianmo turned his head and motioned for her to continue, Long Yuyan raised his eyebrows, took the hazelnuts from the compartment, and opened his mouth while peeling them.

"Shen Bi has a big feature, that is, there is a mechanism at the strings, I am not talented, I happen to know the opening method of the mechanism, so I won her three thousand taels of gold." Long Yuyan raised his eyebrows and smiled proudly, and sent the peeled hazelnuts to Xiao Tianmo.

Xiao Tianmo put it into his mouth and said in a deep voice: "This king doesn't like to eat hazelnuts."

"......" I don't like you to spit it out.

Out of revenge, Long Yuyan put the previously embroidered purse in front of Xiao Tianmo, and said with a smile: "Lord, I embroidered it myself and gave it to you, do you like it?"

Xiao Tianmo pinched the purse with two fingers, his face was full of disgust, and he complained without hesitation: "It's so ugly." Having said that, he still hung his purse around his waist, and complained about his ugliness again, which vividly interpreted his disgust.

"......" Long Yuyan was speechless, "It's okay for you to pay me back if you are ugly, the purse embroidered for the first time, I am baby." ”

"This is the king's."

“…… Yours yours. Long Yuyan waved his hand, too lazy to bother with him, there was really no way to associate this Xiao San-year-old with the god of war who was galloping on the battlefield.

After entering the palace, Ye Su greeted him, and saw that Xiao Tianmo was soaked, and there was an extremely ugly purse on his waist, when did the lord's aesthetics become so bad.

Quietly approached the night owl, "Night owl, what's the matter, the one on the master's waist." ”

"Purse, embroidered by the princess."

Ye Su blinked, turned his head and saw Long Yuyan looking at him with a smile, instantly raised his thumb, and nodded heavily, "Good-looking!" ”

"Poof!" Long Yuyan couldn't hold back her laughter.

The night owl's face is full of black lines, is it really good to open his eyes and talk nonsense like this? Now that the sky has changed, aren't you afraid of being struck by lightning?

Long Yuyan returned to Qingzhu Garden, a little difficult, his own people should have entered the mountain, whether they can win is unknown.

Even if she loses contact with the outside world when she enters the palace, she can't blatantly release the eagle, the secret guards of the palace are everywhere, and it is not too crowded to stay together. I have to think of a way to replace them, I can't teach them to use mobile phones, and there were no operators in ancient times.

When Xiao Tianmo entered the house, Long Yuyan looked like this, holding a pen in his hand, holding his chin, his eyes wandering and he didn't know what he was thinking.

I'm used to seeing her strategizing and cold eyebrows, and now this stunned look is really cute and tight.

"Huh?" Feeling the scorching gaze, Long Yuyan turned around and saw Xiao Tianmo standing in front of the door, looking at him eagerly, "The prince is here." ”

Xiao Tianmo didn't say anything, just looked at her directly, Long Yuyan was puzzled in his heart, and looked at Xiao Tianmo's gaze.

Good guy, there was an ink stain on her chest, the corners of Long Yuyan's eyes twitched slightly, her favorite, the only moon-white gown, was sentenced to death as soon as she changed into it. I am used to using modern signature pens, and I have forgotten that the brush is to be soaked in ink.

"Is there something the prince is looking for me?"

Xiao Tianmo was speechless for a while, where did he come from, but the huge palace only had some popularity in this small Qingzhu Garden, and every time he finished his work, he ran over non-stop.

"Ahem!" In Long Yuyan's puzzled gaze, Xiao Tianmo's gorgeous face flushed, don't look at her, "This is the king's palace, can't the king come over if he is fine?" ”

Long Yuyan shivered instantly, his expression was a little stiff, can you imagine a cold-faced ascetic handsome guy with a muscular body of one meter and nine meters, blushing with a serious face? In Long Yuyan's view, this is not a love story, but a horror movie.

"What kind of expression do you have, you dislike this king?"

Long Yuyan was speechless for a while, pinched his temples, and said, "No, the prince sits casually, I want to go out and do something."

"Where are you going?" Xiao Tianmo was anxious, she was not here, what was she doing here.

Long Yuyan was about to speak, when the voice of the night owl came from outside the door, "Master, Ningjiang's friendly team has arrived in Lingnan and will enter the capital in five days." ”

Xiao Tianmo answered and left Qingzhu Garden. Long Yuyan lay on the crack of the door and saw that the figures of the two disappeared, and then debugged the four-dimensional space station bracelet and entered the laboratory directly.

Long Yuyan and Xiao Tianmo bet that the thing they made was the ancient method, and her ** reserve is relatively large, and one of her favorite items in modern times is stockpiling.

However, even if there is a lot of inventory, her ** can't come out, so I'm going to do some ancient methods**.

The mixture of potassium nitrate, sulfur and charcoal powder is called black, and this mixture is extremely flammable and burns quite badly.

**Explosions occur when burned in an airtight container, producing large amounts of gas and heat.

The volume of the original small solid ** suddenly expands, soaring to thousands of times, and then the container will explode, which is the explosive performance of **.

There are many kinds of potassium nitrate extraction, one of which Long Yuyan prefers is solvent extraction, the extraction process is relatively easy, and the production method is also more convenient.

At 5~10 °C, potassium chloride is dissolved in nitric acid at a concentration of 60%~70%, and extracted with organic solvents to obtain potassium nitrate and hydrochloric acid.

However, in ancient times when science and technology were backward, leaving the laboratory, this solvent extraction method basically failed, and the remaining one was the nitrate clay production method.

The main principle of extracting potassium nitrate from nitrate soil is to use potassium ions in plant ash to replace sodium ions in nitrate soil to generate potassium nitrate.

There are too many bottles and cans in her laboratory, and although there is an explosion isolator, it is not easy to clean up the mess of the explosion, so Long Yuyan decided to go outside the palace to get it.

I took out a sufficient amount of potassium nitrate and sulfur, went to the kitchen to ask for some charcoal, and found a hole in the mountain.

Xiao Tianche and the eldest grandson Yanqing came to the mansion, and the three of them were discussing in the study, and the topic of discussion was Ningjiang and relatives.

"Bang!"

Suddenly, there was a shocking noise, which startled the three people in the room. Xiao Tianche, who was eating candied fruit, was so frightened that he bit his tongue, and his painful facial features wrinkled together.

Although the eldest grandson Yanqing was not as big as Xiao Tianche's reaction, he was not as frightened when he looked at his slightly pale face.

Xiao Tianmo straightened the shaking teacup and frowned.

The three of them followed the sound, and the family members were also panicked, and they put down their work one after another, and came out to see what the sound was, and everyone gathered at the gate of Qingzhuyuan to look inside, all wondering what was going on, but no one dared to break into the princess's courtyard.

"Lord Wang." The housekeeper touched the sweat on the top of his head, and when the voice sounded, he was grinding ink, and with a loud noise, the table shook, and the ink of an inkstone was all on his face.

"Poofha!" Xiao Tianche trembled and pointed at the ink stains on the butler's face, and smiled straight, "Butler, are you going to sing?" ”

The housekeeper remembered that his face was soaked in ink, and he was in a hurry to come out just now, so he rubbed it with a rag and came out.

When a group of people were whispering, the culprit was late, and his clothes and face were full of black ** marks, but fortunately, he hid in time and was not injured by the explosion.

Long Yuyan coughed as she walked out, and saw a group of people standing at the door staring at her with big eyes.

"Ahem, what are you doing here!" Long Yuyan's eyebrows furrowed, "Is there nothing to do?" ”

The housekeeper was the first to react, and ran away as soon as he slipped away, and everyone was stunned for two seconds, and they scattered as birds and beasts.

Xiao Tianche saw that his third brother's face was not good, "Hehe, third brother, there is still something in my house, so I will leave first, and the third brother will talk to Yanqing if there is something." After speaking, he didn't give the two of them a chance to react, and ran out with Daao, as if the soles of his feet were smeared with oil.

Eldest grandson Yanqing: "......"

Xiao Tianmo: "......"

What Prince Che did was not very kind, the eldest grandson Yanqing greeted him in his heart, and then turned his gaze to Xiao Tianmo, "Mo, I'll go back to the house to interpret the prescription, you talk to her, don't be angry." ”

Xiao Tianmo answered in a low voice and followed Long Yuyan into the house.
