Linda's ugly and weird appearance, flickering with the dim candlelight, was like an evil demon walking out of the darkness. She gave Leon a fatal blow, which was a god-strike.

Sure enough, witches and tentacle monsters are the best partners.

The castle at dawn was like a giant beast covered in rocky skin, lying quietly on the hillside. The old housekeeper's room was filled with orange candlelight, and Leon was lying on the bed with a pale face.

For Lean, the housekeeper who served the Sand family for nineteen years. Alice, the simple one, didn't understand the dirty things he did, so she always maintained kindness. But Carrick was different. He was also the confidant of the lord. He had long known Lean, a guy who appeared kind but actually selfish, and even a little disgusted. The matter about his embezzlement was what he told Lea indirectly.

"Alice, let's go. He was frightened and needed rest."

Frightened by Qin Song and Linda, Leon, who had not been sleeping all night, was in a state of weakness in both spirit and body, and could not hide his illness on his face.

After coming out of Lean's room, Alice frowned: "Uncle Carrick, what do you think of what Lean said, the invasion of the devil's minions?"

Linda was the first to arrive at the scene, but she still maintained her usual silence and provided no information. Only Leon was frightened and repeated in a divine manner, with the devil's minions entangled him.

"He is too weak, maybe he is not very sane." Carrick didn't care too much. Lean was 'bed in bed for more than two months, and it was a miracle that he could survive until now: "Anyway, I don't believe that the devil's minions exist in Black Stone Castle. It might be a mouse? Snake or something. Alice, Lean is too old and can't keep a clear mind. I'm afraid it won't last long."

Alice didn't say anything. She was not unfamiliar with death, but she felt a little sad and remembered her deceased father.

Carrick is busy arranging the autumn harvest. Alice does not need to ask about it personally, but stays in the room and continues to study the magic she has mastered. The bronze lampstand has become her toy. In addition to freely changing shapes, it can also be easily separated and made into two or more gadgets. The process of bronze solidification is a gradual process, with gradually increasing hardness and basically mastering time.

In the afternoon, Linda knocked on her door, nodded to her, and then led Alice to the workplace. The hardworking Linda cleaned the room very clean and opened the curtain leading to the inner room. Linda walked to the basket full of wild fruits and vegetables, searched inside, took an orange-yellow Yamanae, and pointed to it.

This is the soybean pear picked the day before yesterday. Perhaps it was ripe. After only two days of storage, it showed signs of rotting. Alice searched in the basket and found that many wild vegetables turned wilted and yellow, some of the fruits had rust-colored rotten spots, and even many small flying insects were breeding.

This is Alice's most troubled problem. Fresh fruits often rot and deteriorate in a short period of time and cannot be continued to be eaten. There is also the "anti medicine" he prepared. Now the demand for it is reduced. Even if the two cans stored in the workplace are covered with lids, after two or three days, they will soon emit an unpleasant sour smell, and the color gradually turns into rust.

In order to test whether the "anti-anti medicine" after deterioration still has the effect, Alice specially found two sailors to test it. The conclusion was that both of them had symptoms of abdominal pain and diarrhea, and their faces turned green after diarrhea.

Fresh fruits and vegetables are not found all year round. If you want the "anti medicine" to truly have practical value, spoilage and corruption are the biggest problem. You should know that scurvy often occurs during sea voyages, ranging from one month to three to four months, while an "anti medicine" that can only be stored for a few days is obviously not practical.

Qin Song has been observing Alice's perspective. With the medieval food preservation level, fruits are spoiled and rotten, which is expected by him. The extended storage time is easy to solve in later generations. You can boil sugar water, add fruits to boil, and canned while it is hot. You can store it for about three months, which is the common canned sugar water. Or you can boil it with sugar water, soak it, and then dry it to make dried fruits, which can also be stored for a long time.

However, these two simple methods were not applicable in the Middle Ages. The main problem is that sugar in the Middle Ages was extremely scarce. Sugar cane, white sugar, and rock sugar, the main raw material for making cane, sugar cane, grew in tropical and subtropical regions, and could not be grown at least in medieval Europe.

In this era, their main food for sweets was honey. Why did Europeans in later generations like sweets? A large part of the reason is that for a long time, sugar was a luxury as expensive as spices. Being able to eat sugar was a symbol of dignity, forming a sense of psychological superiority and satisfaction, and sugar can also replenish enough calories to help them resist the cold.

However, in this fictional world, it seems a little different. It is the medieval time, but the geographical location is different from that of real Europe. In the description of the game, the orcs of the terror are living in the tropical rainforest.

The Black Mist Forest near Black Stone Fort happens to be where the terrifying orcs appear. From this, it is inferred that the climate here is either tropical or subtropical, and it is very likely that the conditions for large-scale planting of sugarcane are met.

This idea made Qin Song a little excited. As long as you can find the seeds of sugar cane, you might be able to plant them in the Black Stone Collar, thus starting the great cause of sugar production. The magical product of sugar can not only create high profits, but also generate too many delicacies.

Of course, it is just a concept now. The most important thing at the moment is to solve the long-term preservation method of fruits without sugar. Qin Song naturally remembered the famous pasteurization method!

Pasteurization was first invented by the French Pasteur to preserve milk. After later improvements, it can also be used to sterilize and preserve fruit beer, wine and juice.

The culprit that affects the spoilage of milk, beer, wine and juice is actually a variety of microorganisms in the air, such as Lactobacillus.

The solution is very simple: remove the slag filter, use pasteurization to sterilize, and then vacuum seal with a glass bottle and cork, so that it can be stored for a long time.

As for pasteurization, it is to heat it in warm water at around 50-60 degrees for half an hour. It can kill most harmful bacteria while maintaining its original flavor and greatly extending the storage cycle.

Pasteurization is suitable for preserving milk, wine, fruit beer, and juice. In the Middle Ages when there was lack of knowledge, it was definitely a black technology beyond the times!

The key is that this technology is not complicated. Under the simple conditions of the Middle Ages, as long as the process design is reasonable, it can also be achieved. Even if there is no strict temperature control, glass bottles and vacuum technology in this era, as long as the oak barrel is properly sealed, even if the fresh-keeping effect is poor, its shelf life will exceed people's imagination.

When the fleet sails far away, buying a few buckets of juice and letting sailors supplement vitamins regularly can easily solve the problem of scurvy.

This is the ultimate antidote to the solution of scurvy!

Of course, there are many ways to deal with scurvy, and there are simpler versions, such as cooking lemons, which can also be stored for a long time. However, because it is too simple and the threshold is too low, it is easy to be imitated and cannot create enough economic benefits.

Starting with juice, sugarcane as a strategic goal. With refined sugar, you can make canned fruits, preserved fruits, candies, etc., which can not only create considerable profits, but also provide a variety of desserts for the cute witches in the future.

Just imagine, on a sunny afternoon with warm spring breeze, a group of lovely and beautiful witches sit together in a colorful garden filled with the fragrance of flowers, eating delicious desserts, drinking freshly squeezed juice, and then piously sing the great gods and giving them gifts from heaven.
