“4NaHCO?+2CuSO4=Cu2(OH)2CO3+2Na2SO4+3CO2+H2O”

Holding the purple bamboo wolf pen in his hand, Chu Fan wrote this reaction equation on the paper crookedly, tilted his head to look at it, sighed softly, and put down the pen.

It has been five days since he came to the Ming Dynasty, and Chu Fan has lived a very fulfilling life in five days, he has completely integrated into this family, and he has lived a leisurely life as a rich son with peace of mind.

Because he knows the direction of history, Chu Fan still has a sense of crisis in his leisure, and what to do in the future is not something that Chu Fan can decide-Chu An is the master of this family-but there is one thing that has to be done quickly, that is, the knowledge in Chu Fan's memory, which must be recorded one by one, this is his greatest wealth as a traverser, and if he doesn't record it, God knows when he will forget it completely.

The original owner of this body not only left him a reputation for talent, but also left him a good handwriting, but it was too difficult to write equations with a brush, and it seemed that he had to get the pencil out as soon as possible.

Closing the notebook made of rice paper and putting it away, Chu Fan stood up, stretched his waist, and came to the bronze mirror.

The young man in the mirror is slightly taller, with clear eyebrows and beautiful eyes, if he was placed in his previous life, he could cos many classic characters in Japanese comics with a little makeup - whether male or female.

But Chu Fan was not very satisfied with this thin and thin body - he was in the previous life, but he was a rough man with thick eyebrows and big eyes.

In order to make this body more in line with his own aesthetics and his own health, Chu Fan began his morning exercise from the second day of his arrival-of course, in order not to be so shocking, he only dared to run laps in his yard and pull ligaments to do push-ups.

After a few days, the effect was quite obvious, in addition to the gradual meat on his arms and legs, his appetite also increased greatly, which surprised and delighted Zhang, who was looking forward to his growth.

"Bang!"

Chu Fan was in a daze in the mirror, and there was a crisp cracking sound from the side of the main room.

It must be Niu Niu, the demon king of the world!

When he thought of his delicate and naughty sister, Chu Fan was angry and loved-the little girl looked so cute, on her pink little face, a pair of thrillingly big eyes flickered, and her chubby little arms and hands were as white and tender as lotus roots, and anyone who saw it wanted to go up and pinch her little face; But she really has no bounds, but all the living things that can be seen at home, she has to catch and play, fortunately she is a girl, if she is a boy, it is estimated that she can go to the house and remove the tiles!

Chu Fan smiled bitterly as he walked towards the main room, this time Niuniu didn't know what trouble had happened.

When I walked into the main room, I saw that the little chubby girl was standing in front of the desk, looking at the ground in a daze. Chu Fan followed her gaze, and couldn't help but gasp, only to see that in the incense ash on the ground, his father Chu An's favorite Xuande furnace was torn apart - one of his three legs was broken, and the jade lion on the lid didn't know where it fell.

Chu Qin and Xian Cha, who were making female celebrities next door, also heard the movement and rushed in, and the situation in the house made Chu Qin, who had always been gentle and demure, also lose her temper, and shouted screaming, "I'm going to die, I'm going to die, this is what my father spent more than a hundred taels of silver to buy...... Girl! You're in trouble this time! ”

Niuniu was already worried, how could she bear to be yelled at by her, her mouth was deflated, and she cried out with a "wow".

"They told you to stay in the house, why did you come here? …… Wait a while, my mother will come back and see what you do! …… I can't help you cover it up this time......" Chu Qin bent down to train Niu Niu, Xian Cha obviously saw a lot, pursed her mouth and picked up the broom, cleaned up the incense ashes, and after cleaning up, she was about to go out and pour the incense ashes, but was stopped by Chu Fan.

"Don't rush to the bottom just yet, let me think of a way." Chu Fan took the basket from her hand and said with a smile.

Chu Qin, who was training Niu Niu, closed her mouth and looked at Chu Fan in surprise - this is not like the little brother in her impression, no matter what happened at home in the past, it was rare to see this Xiucai, but today not only appeared for the first time, but also took the initiative to come up with ideas? It's really weird.

Chu Fan ignored their surprised eyes, pouted his ass and searched for a while, and then found all the parts of the Xuande furnace that were scattered.

After standing up, he took the broken leg and the jade button to look left and right, and gestured to the Xuande stove.

Chu Qin asked puzzledly, "Little brother, what are you going to do?" ”

Chu Fan raised the parts in his hand and said with a smile, "If you break it, won't you have to stick it back?" ”

Chu Qin's eyes widened when she heard this, "You...... Are you going to fool your mother? ”

Chu Fan smiled a little embarrassedly, then looked at Niuniu and said, "Just for such a broken stove, we can't watch the old lady beat Niuniu half to death, right?" ”

"That's it, it's better to be a brother!" Niuniu burst into tears and laughed, rushed up and hugged Chu Fan's thighs.

Chu Qin glared at her fiercely, "You should also fight!" Who told her to be so naughty! Then he looked at the parts with some concern and said, "Even if you have to fool around, how can this stick back?" ”

Her question made Chu Fan scratch his head, yes, in the Ming Dynasty, where there was no 502, how could you stick your legs and jade buttons back?

After thinking about it for a long time, Chu Fan suddenly thought of something, he put down the parts and advised, "Don't move, wait for me to go out and get something, and I'll be back in a while." ”

Looking at his back as he hurriedly went out, Xiancha sighed, "Miss, after the young master woke up, he seemed to be a different person. ”

Chu Qin nodded, "I also found out...... The younger brother talks a lot now, and he knows that he cares about people, and he treats people more smoothly......"

"Yes, yes!" Before she finished speaking, Niuniu jumped and shouted, with tears hanging on her face, "Yesterday afternoon, my brother gave me fried meat to eat, and the big meat slices were added with garlic sprouts, which were delicious...... Brother called it 'back to the pot meat'! ”

When she said this, Chu Qin looked at each other and smiled bitterly - what is this, a dignified talent, and he actually cooks!

"My little brother has really changed...... It's not as dull as before, and I know that I have a shelf for reading every day," Chu Qin muttered to herself, "This time I smashed my head, as if I really opened my mind...... I don't know how happy Dad should be when he comes back. ”

The three girls chatted about Chu Fan's changes, and the time passed unconsciously, about two pillars of incense, Chu Fan came back, carrying a large string of large and small fish bladders in his hand, and the strong fishy smell made the girls in the house cover their noses as soon as they entered the door.

"Bring your embroidery needles, they are punctured one by one, let's boil glue!" Chu Fan said excitedly.

Chu Qin Xiancha suspiciously brought the embroidery needle, poked the fish bladder and couldn't help but ask, "Is this okay?" ”

Chu Fan also helped poke it, and replied confidently, "Don't worry! You'll find out later. "Fish maw glue is not much worse than 502 animal glue, of course he has this confidence.

The fish maw was all punctured, and Xiancha went to the kitchen to find a charcoal stove and a small pot, and after adding some water, he began to boil.

After the water boiled, the fish bladder gradually dissolved into the water, as the water became less and less, the soup became more and more viscous, and when there was only a layer of white gelatinous substance left at the bottom of the pot, Chu Fan extinguished the fire, picked a little glue with chopsticks and smeared it on the broken mouth of the Xuande furnace, and then smeared the broken leg with glue, carefully glued together, and the jade button was also concocted in the same way.

After the glue cooled down completely, Chu Fan tried to break it, and sure enough, the two parts had been firmly glued back, and the crack could not be seen at all if he didn't look carefully.

"Brother, you're so amazing!" Niuniu cheered, and laughed and filled it with incense ash with Xiancha.

Chu Qin pinched a little fish maw glue on her fingers, felt the strong adhesive force, and couldn't help but ask curiously, "Little brother, how do you know that this fish maw glue can stick things?" ”

"Uh~~ I read it in a book."

Chu Fan winked at her slyly.
