In order to cope with the possible arrival of the fish-man attack, the village of Snow Ridge began to renovate the stone wall and build new guard towers and shelters with the guidance and help of the military.

According to the plan, guard towers and outposts will be built on various hills and junctions within five kilometers of the village to provide early warning to the village. The stone walls of the village were heightened and thickened on the original foundation, and a defensive magic array was set up. Find a few suitable places outside the village to build shelters for children to take refuge in before the fighting begins.

At noon one day, Charles walked out of the dense forest to the west with his teammates. In front of them was a group of militiamen from the Snowy Ridge village leading the way.

Each elf in this small group carried a huge basket on his back, and it was evident that the contents of the basket were not light.

Outside the village is now a huge construction site, where villagers and warriors tinkle stones mined from the mountains into the desired shape.

Near the stone wall were rows of cauldrons, many of which had firewood burning underneath, white steam was rising from the pots, and young elves were stirring the contents of the pots with long sticks.

? (￣_￣)?づ?⌒?

Led by Woodward, the newly returned elves dumped the fresh slime corpses in the basket on their backs in the open space not far from the pot.

(???)? ⌒?

As Charles shook his hand, more slime corpses poured out of his storage ring.

The villagers, who were already waiting for their return, immediately took the slime corpses to an empty pot and crushed them into pieces, and then poured the sifted quicklime, clay powder, and fine sand into the pot in proportion.

The villagers light the firewood under the pot and stir it with wooden sticks to make the ingredients mix evenly and prevent the bottom from sticking.

Once the slimes have been boiled dry, the slime mortar will be used to bond the stones of the stone walls.

Before the advent of cement, there were even slime bricks made using a similar method. Although its strength is limited, it is very waterproof.

Charles even heard that some dwarves were working on how to add boiled denatured slimes to cement to make waterproofing materials.

Today's mission is accomplished, and Charles breathes a sigh of relief. They take a break in the afternoon, and then continue to the woods to the west early tomorrow morning to catch slimes.

"Charles!" someone called out to him not far from Charles.

Charles looked over and saw an elderly elf with white hair waving at him.

He immediately trotted all the way to the old elf, "Mr. Fleming, why are you here?"

Fleming grabbed Charles's hand and dragged him into the village, "I've been waiting for you for a while, I heard that you are free in the afternoon, so I will take you to see the results of my research now." ”

Seeing this, Charles could only follow him.

When Charles and the others first arrived that day, the Fleming inquired all the way to find him. Fleming then said that he had a great project and wanted Charles to report it to Queen Victoria.

At first, Charles thought he had met a liar, but it was only after asking the village chief and getting assurances from the village chief that Fleming had been studying something they didn't know was going to see if he had time.

According to Queen Victoria's policy of "giving full play to the advantages of local resources in accordance with the needs of domestic and foreign markets, so that one or several villages can have one or several leading products and industries with great market potential, obvious regional characteristics and high added value", Xueling Village is now mainly engaged in the production of spider silk.

Here, specially bred spiders lie in a small cage under the control of animal trainers when picking up silk, and the worker first takes a roller and dips a little spider silk on the spinning device at the end of the spider's tail, and then stimulates the spider appropriately to let it produce silk while the worker turns the roller to collect the silk.

Between the spider and the drum is a teapot-like kettle, and the newly produced spider silk is no longer sticky after passing through the steam spewed out of the kettle.

Usually the treatment of spiders is also good, and the pupa they ate that day was also a good meal for spiders, and the spiders could go to the woods in the surrounding mountains for two days to release their silk every three days.

At the same time, the spider silk they spit out when they are released has other uses.

Fleming's family runs a spider silk workshop, which he has been doing his own research since he gave it to his children many years ago.

He noticed that Charles was interested in the production of spider silk, so he took Charles around the workshop first.

Eventually, they came to the place where the spiders were kept, and it was like a chicken farm, and the spiders lived in cages stacked on top of each other.

There are workers here who pick the right spiders to mate.

Fleming led Charles to the spider cage in a separate room next door, put on gloves, opened the cage and took out a volleyball-sized spider, and then said to Charles, "Look at its back armor." ”

Charles leaned his head over and saw that the black and white spider had a patch on its back that seemed to have red fluff. He looked at it more closely, and saw that the red one was not the fluff, but the hyphae of a fungus.

Fleming explained to him: "This spider is infected with the red hairy fungus, which is very difficult to eradicate, they make the spider feel very uncomfortable, and in severe cases, it can cause the spider to die. ”

Then he took out a few more spiders, all of which were infected with several species of fungi.

He then led Charles to the cage across the room, and then took out one of the spiders inside to show Charles.

At this time, Charles's eyes narrowed, and he immediately saw the point.

The languid-looking spider's back carapace and abdomen were almost covered with red hairy fungus, but there was a green hyphae growing on its abdomen, and between the two colors of hyphae was an open space.

"Antibiotics!"

Charles almost jumped.

He used Halkala's pharmacy books as textbooks, so he knew a lot about medicine.

In addition to disinfecting the infected area with various methods, the treatment of infection in this world is mainly to enhance the body's immunity through potions, magic or magic magic, so that the body's own immune system can destroy the invaders.

However, the bacteria in this world are not vegetarians, and some bacteria even have a trace of magic, and ordinary methods can't kill them, so who do you talk to?

Bacteria often engage in a tug-of-war with the host's immune system in the human body, which in turn makes the host sick for a long time. What's more, some hosts have been killed by bacteria before their resistance has been raised.

If there are antibiotics, it will be much easier. At least bacteria without magic can be solved, and these bacteria are more common after all.

Fleming's subsequent explanation confirmed Charles's thoughts, and he told Charles that he had discovered that the green fungus could secrete a substance that could kill other bacteria around it when it multiplied.

Then he led Charles to a laboratory not far away, where the temperature was a little higher than outside, and a shelf was full of round petri dishes.

Under Fleming's introduction, Charles saw that he had done a lot of experiments, and the antimicrobials secreted by the green mold could kill many kinds of bacteria.

Fleming then handed Charles a stack of materials, which were animal experiments on the extract of this green bacterial secretion, and the average domestic animal and poultry did not react to this antibiotic in an adverse manner.

Charles, who knew nothing about antibiotics, barely spoke the whole time, just listened carefully to Fleming's introduction, and only asked in detail what the words meant when the other party used some technical terms that he didn't know.

At first, he learned Elven from Halkala's pharmacy books, and he understood most of the medical terms.

Charles didn't know how to get antibiotics, and his knowledge, plug-ins, and gold fingers didn't help him in this regard, he only remembered that the raw materials for penicillin in his hometown were related to cornstarch.

But now that this green bacterium grows on spiders, it's still a question of whether cornstarch can be applied to it, in case people can reproduce through slimes?

Charles, who adheres to the concept of "shut up if you don't understand", didn't say much after listening to Fleming's introduction, but borrowed his desk to help him write a letter of introduction, writing everything he saw and heard here and his little thoughts about "antibiotics" in it, and then asked Fleming to go to Durian City with the letter to find Old Charles.

Xiao Ru believes that the old Charles can see the value.
