Due to the lag in information transmission, Dong Liang did not know what was happening in Luzon Island. After the escort army defeated the British in Huizhou, it began a victorious march.

Only the second detachment and the eighth detachment remained in Baoan to eliminate the remaining British soldiers. Bao Ling had been captured, but Grant was nowhere to be seen.

The city of Guangzhou was also turbulent at this time, and the situation of Zhang Jiayusheng's opening of the restaurant was like riding a roller coaster.

Zhang Yalin is Wenhan's horse boy, and now it is logical for him to join Bao Ling.

No way, the Zhang family's main business is delivering bread to the British on Hong Kong Island. The Zhang family has the best bakers in Guangzhou.

Although these bakers are all Chinese, Zhang Yalin once hired foreign masters to specially train them.

After the foreigners occupied Guangzhou, the happiest family was the Zhang family. With the relationship between Zhang Yalin and Bao Ling, the Zhang family would definitely become the number one aristocratic family in Guangzhou, the first of the thirteen.

In order to please Bao Ling, Zhang Yalin also donated a batch of supplies worth hundreds of thousands of taels when Bao Ling led the troops. Bao Ling also gave him a generous reward and made him a member of the Guangzhou City Management Committee.

Nominally, the city of Guangzhou was managed by Bai Gui. In fact, the person who held the power was the management committee led by the British. The edicts from the Manchu and Qing court were sent to the management committee as soon as possible. The documents issued from Guangzhou were finally delivered to the management committee.

It also has to go through the hands of this management committee.

In less than a month, Zhang Yalin used his power to acquire a large number of industries.

Among them, the one most occupied by the Zhang family was the Su family's Xinghai.

Because the Su family is engaged in the grain industry, it is the upstream industry of the Zhang family. If Zhang Yalin wants to grow bigger, he must take the source of grain into his own hands.

The Su family has long been emptied out, and the inventory in the store is very low. Only a few shopkeepers are left to maintain the basic operation of their own business.

Zhang Yalin annexed the Su family's industry, and also the clerks in the Su family's store. After all, someone still has to do the work.

In the bakery, a man carrying flour bags was bare-chested. The muscles on his body were strong and clear-textured. Sweat mixed with flour formed wisps of lines on his skin.

The man carried the flour bag to the big vat where the dough was kneaded. The other man opened the bag, and all the white flour fell into the vat like a waterfall.

The steward of the Zhang family stood on a high wooden platform in the bakery, observing everyone present with his eyes like a hawk.

These are all things for people to eat, and there must be no mistakes.

After the bread comes out, someone will usually come to taste it, and then it will be sent to Hong Kong Island by speedboat. On the one hand, this tasting is to check the taste, and on the other hand, it is also to test the poison.

There are tens of thousands of foreigners living on the entire Hong Kong Island, and they consume a huge amount of bread every day.

In the egg-beating room, several waiters held mixers in their hands and were rapidly stirring the egg yolk liquid. This is applied to the surface of the bread to make the bread more beautiful and crispy.

This is a separate room, outside the supervisor's surveillance perspective.

I saw a thin worker put a small bottle of liquid medicine into the egg liquid while everyone was not paying attention. This tank of egg liquid was to be used to coat all the bread shipped from the factory today.

This is a bottle of cyanide, which was extracted by people in the chemistry laboratory guided by Dong Liang.

The discovery of metal cyanide can be traced back to 1704. Heinrich Diesbach, a dye worker in Germany, accidentally obtained a dark blue precipitate during the production of dye. As a dye, it has bright color, strong tinting power and excellent performance.

Hence the name "Prussian Blue".

It took a long time for people to understand the composition and preparation method of Prussian blue.

Dong Liang happened to know a little about the principle of making this stuff.

The Chinese established several laboratories under the Ministry of Industry, including chemical laboratories, physics laboratories, electric power laboratories, gunpowder laboratories, steam engine research institutes, and firearms research institutes.

These laboratories and research institutes were established under Dong Liang's instructions, and the talents and equipment collected by the Chinese through various channels will be placed here.

Some of them have clear research directions, most of which were set up by Dong Liang. For example, the Gunpowder Laboratory specializes in the preparation of new propellants and explosives through nitrification reactions. The Electric Power Laboratory studies power generation, power transmission and applications.

Dong Liang can point out a direction for these things, but he can't make a systematic physical object himself. After all, he is not omnipotent. He is just a technician and a practical class teacher. He usually likes to read some scientific and technological journals, which is not considered a professional.

A scientist.

Even scientists are only good at the fields they are familiar with.

The research direction of the chemistry laboratory was relatively free. They used Chinese-translated publications and books to verify the experimental results that had been done in Europe at this time.

And then expand the Chinese’s own basic chemical research.

Dong Liang also guided these people to compile the Chinese's own periodic table of elements.

The preparation of cyanide has long been achieved in the laboratory.

Part of the finished product produced in small quantities is given to the printing and dyeing factory, and part is given to the ANBU.

Fei Changhai is a member of the ANBU in Guangzhou. He has been lurking in Guangzhou as a member of the Su family.

This time the Zhang family merged with the Su family's industry, and Fei Changhai entered the Zhang family's bakery.

He finally had a chance to execute this plan.

The plan had been planned for a long time, which was to poison the entire British population in Hong Kong Island through the Zhang family's channels.

I don’t know what the British think. Their administrative agencies and garrisons on the island are all delivered by the Zhang family who deliver bread every day. Maybe these British gentlemen are used to being served and don’t even have cooking soldiers.

The cooks in the Governor's Palace are too lazy to make their own bread and other staple foods.

But poisoning is not that simple. To poison so many people, you must have a very toxic drug. It is said that one drop of cyanide can poison an elephant.

CN- can inhibit cytochrome oxidase in the human body, causing tissue cells to be unable to use oxygen in the blood normally and causing intracellular asphyxia. Those who consume larger doses can quickly develop respiratory failure and die.

The drug has been solved, and the problem of poisoning has also been solved. The next step is to ensure that it is not discovered. Although the food safety system is not yet perfect at this time, there is already such a thing as poison testing.

Fei Changhai discovered through observation that the manager of the Zhang family who was testing the poison liked to pick the softest part in the middle of the bread to try and eat it instead of touching the crust.

So he thought of mixing the poison in egg liquid, because the egg liquid is brushed on the surface and will not penetrate into the inside of the bread. Even if there is a little bit, the dose is very small and will not show up.

Everything went very smoothly.

Bread processing is usually done at night. At midnight, the Zhang family's clerks pack the bread and send it to Hong Kong Island. These breads are the staple food on the breakfast table of the staff.

…

In the early morning, at the Governor's Palace on Hong Kong Island, Sir Nico got up early. People of his age could not sleep early.

The Chinese servants in the Governor's Palace brought him milk, bread, and bacon in the bread. Sir Nicol, who paid attention to health, also ordered a bowl of vegetable soup.

Half a year ago, an American doctor passed by Xingjiapo and gave Sir Nico a lot of health advice, such as eating less meat and increasing the intake of vegetables and fruits.

The accompanying Chinese doctor also prescribed a health prescription for Sir Nico to take regularly.

In the past six months, Nigao feels that his body is much better than before, and he rarely gets out of breath when climbing stairs.

He took a sip of the vegetable soup first. It was fragrant and fragrant. It is said to be a seasoning spread from the Qing Dynasty. It looked like ground salt. Just a little bit can make the vegetable soup taste delicious, but the price is very high.

It’s expensive, but you don’t need to use a lot each time, so it’s acceptable.
