If the sales conditions set are not too harsh, gunpowder factories can still make considerable profits now.

He visited the imperial physician Cai Youxi again. The old doctor had a strong desire to learn. He was extremely happy to see Song Chen coming, so he prepared a basket of questions to ask him.

This time, Song Chen also brought him a mysterious gift, a precision instrument that allows people to see the microscope invisible to the naked eye, called a microscope.

This is the result of the joint cooperation between Song Chen and A Niu. It was made by hand and took a lot of effort. With this, it can fully prove the existence of the microbial world, which laid the foundation for subsequent research.

There is another gift that is not that good, a box of teenage mice. Song Chen said that these teenage mice are very similar to human bodies, and the experiments on them are excellent.

During this talk, Song Chen talked about penicillin, as well as related staphylococci, streptococci, cells, cell walls, penicillium, petri dishes, etc., saying that if penicillin is successfully manufactured, it will be of great merit and will save thousands of lives.

However, penicillin cannot be produced in a short while, and it should not be consumed too much time on it.

Doctor Cai was just skeptical, but in the end he agreed to Song Chen's request to put cowpox first.

Song Chen knew that Penicillium had to be cultivated through generations before it could be successful. It was correct to let the old doctor focus more on cowpox, and it has been promoted on a small scale.

Of course, he also had to meet Zhang Yuniang, the first reporter of the Song Dynasty, so he naturally had to take Li Xiaofei with him. After all, he promised her that he could not meet this "beautiful young man".

Song Chen didn't go to see Zhang Yulang's women's clothing. This kind of thing is enough to think about it in his heart, and he can't show it. He came to meet her to talk about the serious matters and was preparing to publish a few articles on finance in "Lin'an Jiewen".

When talking about this, Zhang Yuniang said that she would meet the 'article' written by Song Chen.

She expanded and saw that the title was "Credit is a good matchmaker" and "financial induced labor". The title was shocking, and Zhang Yuniang felt like she met a soulmate.

The result is that the title is very coquettish and the content is very serious, but the writing is too serious, and not many people may want to read it.

Zhang Yuniang said that she could publish it, and she had to make it moisturize it.

Because she didn't know what she would change, she said that he went to Fujian Road and couldn't see the revised manuscript, so she didn't agree until she promised to send the revised manuscript to Fujian.

But after hearing this, Li Xiaofei was so worried. Do you want to spread love in private? I immediately made a plan.

Li Xiaofei asked Song Chen again why he signed the "Yong Swearing No Two" to publish an article.

Song Chen explained to her that this was his pseudonym, and Zhang Yuniang said that his pseudonym was really second.

When Song Chen thought the matter had been agreed, Zhang Yuniang asked for the "advertising fee", which surprised Song Chen.

It’s good if I don’t ask you for royalties, but you’re still embarrassed to charge me for advertising fees.

Unfortunately, when he negotiated with the beauty, his IQ dropped sharply. He paid 500 stags directly for the last few articles, and it was a prepayment.

Zhang Yuniang revealed a set of data. The current newspaper circulation is five times that of the past. There are branches in Yuhang, Qiantang and Jiaxing. Currently, a page as big as a palm is 200 cents. What I mean is Song Chen’s “friendly price”.

Song Chen did his homework in advance, and what she said was true. Before she changed her mind, she paid the money to save the weirdness of her monster.

They also went to see Zheng Sixiao and Lu Zonggui's two masters to see how they developed various anti-counterfeiting technologies. They are now both imitation experts. Before leaving, Song Chen told them not to waste their painting skills.

When I returned to my residence, Imperial City Department's spies are protected around the clock, which is quite safe.

However, Song Chen did not have much affection for this protection model. He thought that his safety must be maintained by his own people.

This time, he had 500 sergeants in the yamen, and he would have to use his own soldiers to protect his safety.

Every time he went home, he would go to Uncle Tong's Aunt Tong's house and told them that A Niu was safe because he had the skill of making glass and could create a huge amount of wealth. He would not be willing to hurt him. In this way, the old couple could barely cheer up.

Then Song Chen said that he had to wait two more days before he could set off for Quanzhou after the people on his side gathered.

The next day, after the suspension of work and the troubled trouble, Linjia Road was officially opened to traffic. Song Chen attended the ceremony, and Xie Guoming learned Song Chen's meeting ceremony very well.

The scene was very lively. After all, two months ago, he was building momentum, and he was a huge newspaper such as "Lin'an Jianwen" and published advertisements, and invited a troupe to attract popularity.

The charging model is mentioned every time. At one time, ten copper plates have been used to promote the six lanes on the road, and the flat road surface is solid, which saves five hours of back and forth between the two places.

It also comes with a very realistic oil painting. On a road that is beyond the sight, the family enjoys the feeling of flying in a four-wheeled carriage equipped with shock absorbers.

On the day of opening, there were a thousand carriages and horses of all kinds and collected ten cents of money, although this was too small compared to an investment of one hundred thousand cents.

However, this was the first day. In the next few days, the traffic volume reached 20,000 times a day, and the toll collectors at the road also increased, because a lot of copper plates were collected every day, and security forces must be increased, and road cleaners also need to increase, which are all expenses for maintaining the road.

Compared with the toll collected, the expenditure is drizzling. The interest expenses for the first year are stable. After four years, the principal can be paid in advance. At that time, the income from this road can provide support for the "Wu Mu Plan".

So far, Song Chen has been doing well. Although his 15,000 yuan dividend was gone after fulfilling his promise, his cash cows will continue to bring him dividends.

They received letters from Fan Tianshun and Niu Fu one after another. The two of them scolded Song Chen, but they really scolded him, saying that they would beat him up next time when they saw him.

This time, even Song Chen felt that he had done too much. He directly transferred 300 soldiers in Fancheng. These 300 people were veterans who had seen countless deaths. These soldiers were the souls of Fancheng.

However, Song Chen also lent the poisonous general Gundam to his two hundred soldiers and "detained" them. He did not send a letter to curse people because the two had no friendship and wrote any letters. He directly stamped his feet in Ezhou to scold Song Chen for being shameless.
