After his mother left, Li Siyuan lay on the bed and couldn't sleep for a long time, he missed home, his fiancée, and the brothers who worked hard together! But no matter how much he thought about it, he himself knew that he might not be able to go back! Thinking about the past life, thinking about this life, after a long time, Li Siyuan fell asleep, and when he fell asleep, there were tears hanging from the corners of his eyes!

The next morning, Li woke up very early, boiled an egg for Li Siyuan, baked a few hot cakes, cooked some wild vegetables, and waited until everything was ready, before he came to wake up his son to eat!

Li Siyuan slept late last night and didn't have an alarm clock to wake him up, so his habit of running in the morning, which he hadn't broken for many years, was interrupted on this day!

After getting up, Li Siyuan thought about washing up, but when he came to the yard, he tragically remembered that this was the Tang Dynasty, and there was no facial cleanser and toothpaste and toothbrush at all!

Li Siyuan was very curious about how people in this era solved personal hygiene without facial cleanser and toothpaste and toothbrushes, so he came to the well and watched how his mother did it!

The mother, who was brushing her teeth, saw her son coming, and hurriedly asked, "Are you feeling better, do you remember anything else?" ”

Li Siyuan shook his head, looked at his slightly disappointed mother and said: "I slept last night, but I didn't remember the previous things, but in my dream, I dreamed of a white-bearded fairy, he taught me a lot of things, but he told me enough, and the previous memories were not returned to me, which is my tuition for learning skills!" ”

After hearing this, Li Shi's face was overjoyed, and he hurriedly put down a branch in his hand and said: "My son is really good, he can worship the gods as a teacher in his dreams, and he will definitely be able to worship the marquis and glory in the future!" As for your previous events, I can't remember it and it's nothing, but it's just some children's play! Come, tell my mother what skills the gods have taught you? ”

Li Siyuan didn't expect that his mother would believe such a simple lie, and he didn't have the slightest doubt, but when he thought about it, he was relieved, there was no science in the Tang Dynasty, and for some things and phenomena that he couldn't understand, everyone was more willing to believe in some theories of gods and ghosts!

Li Siyuan looked at his happy mother, and said with some shame: "The gods have given me a lot of skills, but because I teach too much, I can't tell you what they are for a while, and I will tell you slowly in the future, mother, are we using these things to wash our faces and brush our teeth?" ”

Li Shi looked at the ashes and willow branches pointed to by Li Siyuan, and complained: "This immortal is real, all memories have been taken away!" After finishing speaking, he seemed to remember the taboo that he shouldn't slander the immortals, so he hurriedly snorted a few times to the ground, and then muttered to himself asking the gods for forgiveness!

Li Siyuan saw this, and his face was black, but people at this time were like this, and he couldn't change anything!

After a while, Li probably felt that the gods had forgiven her, so he stopped talking to himself, and then said to his son: "What is in this basin is grass ash, which is used to wash face and hair; The contents of this basin are willow branch water and ginger juice, which are used for brushing teeth. ”

Li pointed to the two pots of things in front of him that didn't look very clean and patiently explained to Li Siyuan, and then picked up a branch from the side and handed it to Li Siyuan: "Take this, this is a willow branch, let's mash one end of it, remove the hard things, and leave some soft tendons, we can use this to brush our teeth with the water in this pot!" Li Shi said while giving Li Siyuan a demonstration!

Li Siyuan looked at the things in front of him, and only after a long time did he make up his mind to use them, he kept hinting to himself in his heart: These are all original, additive-free good things, you should cherish them, don't dislike them!

When using plant ash, Li Siyuan did not have any other discomfort except for a slight psychological response; But when he brushed his teeth with a branch, it was different, because he had never used this willow branch, brushing his teeth was always light and heavy, and after a while, Li Siyuan's gums began to bleed!

Li Shi looked at Li Siyuan's embarrassment on the side, and said with a happy smile: "You always didn't brush your teeth before, but now you bleed, in the future, you remember to brush every day, and you won't bleed when you get used to it!" ”

Li Siyuan hatefully dropped the willow branch toothbrush, feeling aggrieved in his heart, this was really something that he couldn't dream of before! No, I have to change this life, at least the problem of the toothbrush must be solved, otherwise if I live to be dozens of years old in the future, I will not be suffocated to death!

Thinking of this, he hurriedly finished washing, came to the dining table, and urged his mother: "Mother, come and eat, after eating, I will make you a magic weapon that the gods taught me to make, and I promise that it will be a pleasure for you to brush your teeth in the future!" ”

When Li heard that his son was going to make things for the gods, he hurriedly said, "You eat first, my mother is eating after washing these clothes!" What do you need to make that magic weapon, the mother who doesn't have it at home will buy it for you! ”

After hearing this, Li Siyuan was no longer polite, buried his head in eating the few rough meals, and said to his mother while eating: "Mother, do you have pig hair at home, so you only need pig hair and a few small pieces of wood!" ”

After hearing this, the Li family was very puzzled, what kind of immortal magic weapon would use pig hair? Although she was puzzled, she didn't ask much, and said to her son: "This thing is not available at home, if you can use it, I will go to your Uncle Zhou's house to ask for a little later, his family kills pigs and sells meat every day, there should be a lot of this thing!" ”

After listening to his mother's words, Li Siyuan nodded, and then instructed: "Mother, if his family has more of these things, you can take a little more, and I will make a few more, and wait for the afternoon or tomorrow, let's take it to the market to see if we can exchange some money and come back!" ”

After hearing this, the Li family hurriedly asked, "Son, the magic weapon of the immortal family, won't your master be angry if you exchange it for money?" ”

Li Siyuan said with a smile: "No, no, Master said, after learning these things, we must promote them to benefit our people of the Tang Dynasty, and at the same time change our living conditions!" ”

Li was still very happy when he heard Li Siyuan say that it would benefit the people of the Tang Dynasty, but in the latter sentence, Li heard the smell of copper, which made Li very unhappy, and hurriedly persuaded: "Son, we have learned the skills of the immortal family, but we can't be willing to fall and do that business thing, otherwise, after your father comes back, he will definitely not spare you!" ”

Li Siyuan naturally knew what his mother meant, in ancient times, due to the ideological constraints, everyone was heavy on agriculture and light on business, and everyone had long thought that businessmen were a group that valued profits and ignored righteousness, so few people were willing to put aside their identity as farmers to be a lowly businessman!

"Mother, don't worry, I won't be a businessman, I will be a general in the future, and I will invite dozens of servants to serve you and Daddy!" Li Siyuan looked at his mother who was feigned anger, and hurriedly said some words of relief, he didn't want to make his mother angry because of this little thing!

The two of them were gossiping, Li Siyuan was also full, he wiped his mouth, and said to his mother: "Mother, I'm full, the eggs are left for you to eat, I'll find a few suitable pieces of wood for now, you can eat after you wash your clothes, and then the food will be cold!" ”

Li agreed, and then washed his clothes by himself!

Li Siyuan knew that these clothes were not from his own home, and it must be his mother who took over from a large family in order to supplement the family, and Li Siyuan didn't ask much about this, because now he can't support this family with his own hands, of course, he is not qualified to ask too much!

Li Siyuan quickly found some wooden sticks of just the right size, asked his mother for a sickle and an awl sharpened from iron wire, and began his own work of making pig hair toothbrushes!

He first sharpened the sticks into the shape of a toothbrush in his memory, then rekindled the fire on the stove, burned the awl red, and drilled rows of small holes in the sharpened wood!

After doing this, Li Siyuan looked up at the direction he wanted, and calculated the time in his heart, it should be almost eleven o'clock, and then he looked at the dining table again, and found that it had been cleaned up, and his mother was gone, only the washed clothes were dried in the yard, thinking to himself, it seems that his mother has gone to Zhou Shu's house to get pig hair, so let's wait first!

Li Siyuan sat in the yard waiting for his mother to come home, thinking that maybe he could earn the first pot of gold in his life in Datang with this simple toothbrush and help his parents improve their lives, so that the future would be much better!

Li Siyuan, who was sitting in the courtyard basking in the sun, looked at the simple version of the wooden handle of the toothbrush he made, and suddenly thought of a question, the Tang Dynasty did not have industrial glue, so how should he fix the pig hair on the toothbrush? It is definitely not possible to tie it with a thread, in that case, your mouth will definitely be full of pig hair after brushing your teeth!

Li Siyuan frowned and thought carefully, what could replace glue?
