Xiao Heizi is the most typical loyal slave in feudal society, so Yang Guang couldn't help but hold on to his second-hand man. "Now, Xiao Heizi, you are really handsome, at least much handsome than the Luo brothers!"

However, his concern did not last long and his face soon became gloomy. "But are you just rushing to escape? You actually disregarded the old man of Yuanfang? Humph! What's the use of such a slave master!"

As he said that, he pushed Xiao Heizi away. Xiao Heizi was shocked and opened his mouth but said nothing. Instead, Chao Yuanfang next to him got the truth from the sergeant who escorted Xiao Heizi in and explained it to him.

"Second Young Master, you misunderstood. Xingzhi is very weak, but before he ran to the rice shop opposite to find the Young Master, all the old and young people who had already called me out, they were all fine, and my 70-year-old mother still carried her back..."

Yang Guang's face then calmed down. Xiao Heizi was still scared and dared not say a word. He knelt on the ground and shivered all over. He was very afraid that the second young master would not want him anymore and drove him away.

He would rather accept any punishment than be driven away. As a horse, Black Pearl would recognize his master. In fact, humans would recognize his master even more. At this time, the little black-sin had bound everything to his master.

Be a slave for life and serve the second young master for the rest of his life. Even if one day he will start a family and have a son, none of this will change!

His greatest ideal in life is to be the follower of the second young master for generations. He serves the second young master, his son serves the second young master, and his grandson serves the second young master, and his descendants are endless!

"That's it, but Yuan Fang, your family is really safe?" He now took Chao Yuanfang's hand and cared for him. It seemed that he liked to hold men's hands recently, different men's hands!

Chao Yuanfang was very moved because the Second Young Master was very good to each of them. Although strictly speaking, he was not the second Young Master's fixed team, he had long regarded himself as the Second Young Master's person from the bottom of his heart. In this world, except for his 70-year-old mother, he would treat the Second Young Master as an imperial edict, and he would resist without any doubt and execute it without hesitation!

In fact, he was sad just now and shouted herbs, mainly because some secret medicines jointly developed by him and the second young master were also among them, such as the first contraceptive pill in ancient times!

It is very convenient to want contraceptives in the 21st century. It costs more than 10 or 20 yuan to go to a pharmacy. There are all kinds of contraceptive injections and various brands of contraceptives and TTs with interest.

But this was definitely a serious problem in ancient times more than 1,000 years ago. The reason why Yang Guang was very attentive to this matter was because he knew that he was Yang Guang, one of the emperors who had the most and most frequent women in official history!

But if you can have a woman, you must not have a child. But these days, there are no ultra-thin, high and light TTs, which are numerous in various types. He can only speed up the research of this aspect based on his later research and memory in this area. He can only accelerate the study of an oral contraceptive pill with high success rate and common medicinal materials!

He really had no idea of ​​benefiting the vast number of women and comrades in feudal society. The reason was that he didn't want dozens of children to call him father as soon as he entered the door, tall, fat, thin, beautiful, and not good-looking little boys and girls. If he was not lucky, he would have two cleft lip and mentally retarded. He couldn't bear that kind of heart.

It’s not that he doesn’t like children, but his concept of children must be less and more refined, and he must follow his 21st century path since childhood to educate elites!

In addition, he is a time traveler and is not really Yang Guang. He knows very well that his first child must have a baby with Xiao Meiniang, otherwise Dugu Jialuo would not have supported him so fully as the prince and abandoned Yang Yong!

Besides, how old is he? He is only 16 years old and becomes a father at the age of 16? Go, he is not ready at all!

However, it was very difficult to study modern contraceptives like Yuting in ancient times, and the methods used in different countries and regions were also very different.

A contraceptive prescription recorded in Egyptian papyrus can be said to be the earliest method of drug contraception in humans. This prescription indicates that crocodile feces and paste substances are mixed into strips and placed in Y, which has the effect of absorbing sperm Y and blocking sperm 0 into **.

Indians are almost the first to learn that salt has contraceptive effects. An ancient medical book suggests that women can use a piece of "oil-dipped rock salt" to put it in YD before having fun, and sometimes, they can also apply honey and butter.

Before the 13th century, elephant feces were an important "topical contraceptive pill" they used. Modern scholars have conducted research on this, and the results are quite interesting. elephant feces are acidic and do have sperm-killing effects, but crocodile feces are alkaline, which is conducive to the survival of sperm.

Another civilization was born in Rome, where local women used the "olive oil contraception method", which was recommended by Aristotle, a great philosopher in the 4th century BC.

The more reliable method was proposed by a Roman obstetrician and gynecologist in the 2nd century AD. He suggested making "embolics" with wool, mixing them with some paste that can slow the movement of sperm, and then plugging the cervix of the sperm.

The above methods are all foreign methods. The Chinese nation has relatively more methods for five thousand years, first of all, saffron!

In fact, it has long been recorded in the folk that saffron is a secret contraceptive recipe from the palace. It is said that if the emperor does not like a favored palace maid, he will ask the eunuch to hang the palace maid upside down and clean her lower body with saffron liquid, so that the semen in the palace maid can be cleaned.

At the same time, there is also a precious medicinal material, musk. Musk has a significant excitatory effect on the uterus, which can gradually increase the contraction force of the uterus and accelerate the rhythm, thus playing a role in inducing labor. Therefore, pregnant women should not use it.

In women, amenorrhea is often caused by stagnation of qi and blood. Musk can activate blood circulation and unblock menstruation, so it is also widely used in regulating menstruation. Applying musk wind-chasing ointment or using musk rheumatoid oil to massage at acupoints can treat dysmenorrhea. According to clinical statistics, the effective pain relief is more than 90%.

However, saffron is also a poison for women. Musk is very expensive. Although it can be used for contraceptive effects or even induce abortion, it still has too much harm to women's body!

Yang Guang also knew that another magical thing came from ancient Greece. The ancient Greeks used a "oral contraceptive pill", which was said to be a magical decoction. The Greek Hippocrates wrote in one of his works: This decoction called Mixi, which is called Mixi, can make women infertile for a year if taken with water!

When Yang Guang was studying Chinese traditional medicine in the shadow army, he was very interested in ancient contraceptive drugs. Even in the end, even foreigners followed and actually got the Mixi formula mentioned by Hippocrates. Although he was cursed by the school beauty Zhang Lihua before he could go to the laboratory to verify it!
