Li Ruixin and Li Ruijie were stunned by Li Ruixiu's arrogant and domineering and arrogant attitude, you must know that they are the offenders, and they have just been driven out of the mansion of Princess Yongning, the only backer, Li Ruixiu still dares to sarcastically mock the six doors so sharply, and dare to touch others like this. Pen ~ Fun ~ Pavilion www.biquge.info How did Zhang Da become a 'spy', what is a spy. Zhang Da was sold into slavery, isn't it good to be driven out of the house to restore his status as a civilian, what kind of threat is this, it is better to be a servant in a high-ranking family than an ordinary small family, but our family is not a powerful high-ranking family.

After Li Ruixiu finished speaking, he didn't give anyone time to react, and went directly into the bedroom on the west side, locked the door, and prepared to sleep. Of course, he knew that it was not good to sleep immediately after eating, but it was dark after dinner here, and the smell of candles made Li Ruixiu feel uncomfortable and miss the taste of nicotine.

On the second day, Li Ruixiu woke up in the dark, he found that he had changed back into himself, which made him very happy, after sleep, his second personality was silent, he didn't have the opportunity to wait until natural sleep when he switched personalities before, and he encountered all kinds of accidents, and this time he changed back to the master personality It was really an unexpected surprise.

Li Ruixiu happily recalled what the second personality did yesterday, and couldn't help but feel palpitations, this is ironclad to offend Chang Yu to death, it is really possible to cause trouble every time he changes his personality.

Li Ruixiu thought about it for a long time, and found that it was useless now, so he could only sit cross-legged and practice internal strength first.

After running for a week, Li Ruixiu exhaled a breath of turbidity, took out a strip of cloth to cover his eyes, and went out to the hall for breakfast.

Chang'an reported after breakfast, saying that he found a Xiucai surnamed Nanzi Wenliang, he was born in a farmer's household, for scientific research, the family's house and land were sold, used to be the head of the Ministry of Industry Wang Da's family as a Xixi, the new emperor ascended the throne, Wang Daren was demoted and dismissed from the capital, he also lost his job, now he rents a house in Nancheng, writes letters and sells calligraphy and paintings every day, and now he can't make ends meet, and is very willing to come to Li Mansion to teach.

Li Ruixiu nodded and said, "Since it is the west seat of Lord Wang's family, then it is good to think about Wencai, you call Zhang Da, and the two of them rent a carriage and invite Mr. Nan to help him move by the way." Aunt Zhang went to take the main house in the south for her husband to live in, and then cleaned the other west wing room as a study for her younger brother's study. ”

Chang'an saw that Li Ruixiu was gentle and elegant at this time, and he was very easy to talk, so he mentioned the matter of Aunt Ying who he bought back last night, Li Ruixiu nodded, saying that he knew, and asked Aunt Zhang to move in with Zhang Da, and Aunt Ying would accompany Li Yujiao to live in the future.

All arrangements stopped, Li Ruixiu continued to practice behind closed doors, and finally practiced the dog-beating stick method with a green bamboo cane for half an hour. After lunch, I went to the study in the East House to prepare to build a spaceship.

On the table in the east room was still a bowl of stone grinding powder that the second personality had ground yesterday

, Li Ruixiu knew that the second personality wanted to make a pen called "pencil" in the fairy world, this kind of pen is widely spread in the fairy world, easy to carry, simple to use, that is, the words written with it can be erased, so the immortals use it to carry out work that needs to be modified and will not be used to write important things, there are other pens in the fairy world that are more widely used, but the pencil should be the easiest to make.

Li Ruixiu thought back to the pencil making process, there was the most rudimentary plan in the fairy world, he felt that he could try it, so that he could have the first immortal weapon. And the pencil is very useful for building spaceships, and many parts need to be drawn.

Li Ruixiu first asked for a bucket of water and a basin, said that the ground graphite powder was poured into the basin and added water, stirred with chopsticks for a long time, the immortals thought that this could wash away the impurities in the coarse graphite powder, and then to filter out the graphite powder, Li Ruixiu did not have the filter paper used by the immortals, so he took a tribute of fine sand clothes, folded it in half once, tied it to the flower brace for embroidery as a strainer, and then tirelessly filtered graphite powder, the filtered graphite powder was put on a plate to dry, Li Ruixiu did it for the first time, the amount was not very large, I only got a plate of graphite powder.

Below to add an appropriate amount of water, sulfur, rosin and other substances to boil, Li Ruixiu stopped, frowned and thought, what is "wait", immortals are always used to omitting unimportant things, but this is really bad for Li Ruixiu, in addition, he feels that he needs to build an alchemy room, which is what the immortals call a "laboratory", in order to continue, you can't boil these things on your own stove, the immortals have records, the gas produced by sulfur when it is heated is poisonous, Even the immortals couldn't stand the poison, let alone a mortal like themselves.

The laboratory in the fairy world must first have good lighting, and Li Ruixiu remembered that the lights in the room were so bright, as if it were daylight; Secondly, there must be "electricity", the world of the immortals is very dependent on electricity, electricity is thunder and lightning, and the immortals can use the energy of thunder and lightning to do everything; In the end, there must be "computers" and "networks", which are the core of the laboratory, no matter what the immortals do, they will use this thing, Li Ruixiu does not understand what it is at all. There are still a lot of strange things, Li Ruixiu feels that it is getting bigger and bigger, it is so difficult to build a laboratory, and it is necessary to wait until his grandson's generation to build a spaceship?

He took a deep breath and warned himself not to be discouraged, he already had a fairy fate, much ahead of ordinary people, so he had to be down-to-earth. Li Ruixiu decided to study the pencil first, and then find a way to set up a laboratory.

He blindfolded, picked up a green bamboo cane, and asked Aunt Zhang to accompany him out to buy things, Aunt Zhang put down the work in her hand, helped Li Ruixiu, and the two slowly arrived on the street.

The first one to go was the carpenter's shop, Li Ruixiu asked the work to use the scrap scraps, and made a mold for him to fill the pencil lead, requiring the two halves of the mold to be tightly sealed, and after closing together, there is a hole with a diameter of six centimeters in the middle, the length of this mold is five inches, and the hole inside is four and a half inches long, one end is open and one end is tightly blocked, and then the pencil liquid is poured into it to cool down. He also let the work to make a pencil shaft with an outer diameter of two points and an inner aperture of six centimeters, which is also a two-half structure, and the same is a porcelain with one end, and after paying the fixed money, he agreed to come over to get the mold later, and tomorrow the carpenter shop will send the pen shaft to Li Ruixiu's house.

Then Li Ruixiu went to the pharmacy, bought a pound of rosin and sulfur, and then went to the blacksmith's shop, and bought a small pot and a soup spoon.

Coming down is a pen and paper shop, Li Ruixiu relied on his previous experience in reading and literacy, and bought a knife of "ten knife heads" paper, which is thick and smooth, very similar to the paper used by the immortals to write, and bought a set of ordinary four treasures of the study for each of the two younger brothers, bought a set of high-end four treasures of the study for Mr., and bought five knives of single xuan, ready to be used by the younger brothers to learn words. I paid an extra ten cents and asked the guy to send the things straight home.

In the end, I went to the bookstore and bought three sets of the Four Books and the Five Classics and a set of children's enlightenment books, which cost nearly 25 taels of silver, and asked the man to send them home.
