After leaving the castle, Li Yu first took out the map and checked the direction he wanted to go next.

The map was hand-drawn by himself, because the manager did not allow Li Yu to copy it, so Li Yu took a photo with his mobile phone, and after returning to the room, he drew it bit by bit on his notebook.

Apart from the lack of the statue of the Silver Moon Goddess and the lack of coloring, it is basically not much different from the original.

But according to Fausto, this map has a history of hundreds of years, and some places may not be that accurate. However, Li Yu had no better choice at hand, so he had to make do with it.

Maybe when he is free, he can use a drone to draw a more accurate map. Li Yu chose to bring a solar power bank with him the last two times he came here.

This kind of power bank is a solar panel with monocrystalline silicon added to an ordinary power bank, which directly uses photovoltaic power generation without being connected to a circuit. It is most suitable for Li Yu's current situation.

In this way, he has initially solved the charging problem of drones and other electronic devices. He no longer has to remove the batteries and carry them back and forth.

With the power bank, Li Yu naturally thought of a larger battery.

However, the weight of batteries is usually not light. Excluding clothes and shoes, the weight Li Yu can carry at this stage is only about 3kg each time.

Most of the large-capacity batteries on the market exceed this weight. As for smaller batteries, they are not much different from power banks.

Of course, there is another way, which is to disassemble the batteries and bring them over in batches before assembling them. However, Li Yu's current electricity consumption is not large, and he does not have such a strong demand for batteries for the time being.

In addition, his religious group has not yet been mobilized, so he can only rely on Ilea for safety. If he really makes too much noise, he may cause some unnecessary trouble.

So Li Yu pressed this idea.

The first time he chose to explore was the woods not too far away from the castle, where Ilea had passed through when she escaped from Rock Snow City back to the green fields.

However, it was already late at night when Li Yu appeared, and he couldn't see the surrounding environment clearly at that time. Now, when he comes back during the day when the sun is shining, he can finally see the true appearance of this place.

The trees in the forest are mainly fir trees. They have gray-brown bark. The outer bark is often split in long strips, revealing the light red inner bark. The trunks are tall and straight, growing upward, and the leaves are long and thin strips.

, branching to both sides, evergreen all year round.

According to the markings on the map, this is also the forest farm of the Arias family, which also means that nearby civilians cannot cut down trees at will here. If they are caught illegally cutting trees, they will face hefty fines.

Li Yu casually marked the fir tree on the map. As one of the most common tree species, fir trees are indeed suitable for being cut down and processed into wood for building decoration. In addition, the resin in the bark can also be used as an adhesive.

, fir leaves can also be distilled to extract essential oils.

The paper used on the Bratis continent today is still mainly papyrus and parchment. Although both types of paper can be written on, they are not actually "paper" in the strict sense and have their own flaws.

If he successfully introduces papermaking technology to the Bratis continent in the future, cedar trees can also be used as raw materials for paper pulp.

In addition to fir trees, Li Yu also found dandelions in the forest.

With its extraordinary ability to reproduce, this little thing can easily spread all over the world, and once it takes root, it is difficult to eradicate.

It is undoubtedly a scourge to gardeners and farmers.

But this Asteraceae plant itself has quite a lot of uses. According to Clara, every time dandelions sprout, many nearby farmers will dig them up, wash them and take them home to eat as wild vegetables. All parts of dandelions can be eaten.

And the seeds can also cure diseases.

People with gastrointestinal discomfort can feel much better by eating some dandelion seeds. Some people who bump into their arms and legs or have boils can heal faster by applying some dandelion seeds on them.

And Li Yu knew that it was not just that. Because of its anti-inflammatory function, dandelion could cure many diseases. In addition, the roots of dandelion could also be soaked in water and drunk. When there is no tea to drink, drinking some dandelion water is also good.

There are still a lot of bracken in the forest, and many villagers come to dig them when there is no food.

Fresh bracken itself is poisonous, but as long as it is blanched and you don't eat too much at one time, it won't be a big problem.

The little maid said that the Arias family treated the tenant farmers quite well. Although they were not allowed to cut down trees at will and hunt in the forest, they were at least allowed to dig wild vegetables, catch small animals such as squirrels, and occasionally improve their food.

There are some very strict and money-grubbing lords who charge money no matter what they do, including the use of grassland, woodland, and bread ovens, but the people below have nothing to do. After all, according to the laws of the Red Lion Empire, the land, and the people on it

All animals and plants belong to the lord.

Of course, if you go too far, the free people in the territory will be gone, leaving only serfs who cannot farm so much land, and the lord will also suffer losses.

Not only was Li Yu looking for familiar animals and plants himself, but he also gave each of Clara and the four children a Morning Light Notebook and a pencil, asking them to draw all the animals and plants they knew, and those they didn't know first.

Write it down, especially remember to highlight the special features. Li Yu will write it down and search it on Baidu and Google.

Compared with boring calculations and memorizing multiplication tables, of course hiking and painting classes in the forest are more enjoyable. The little maid can also legitimately fish everywhere.

Even though Li Yu set up a reward of half a silver coin, Clara seemed to be still at a heartless age. As long as she had enough to eat and a place to sleep every day, she didn't care much about how much money she had in her pocket.

Moreover, her parents sold her early and then disappeared without a trace. She did not need to make money for the family like the four little ones, so she was not very interested in the rewards offered by Li Yu.

Just as a group of six people were walking around, investigating and outing, the sound of horse hooves coming from behind destroyed the peace and tranquility in the forest.

The two riders galloped towards this side, calling Merlin's name continuously along the way.

Li Yu stood still, waiting for the two of them to approach. The two riders were obviously relieved after seeing him. One of them, a handsome young rider, said to Li Yu, "I am Jordi, as everyone calls him.

I am the Knight of Purple Sparrow, and this is my squire Karl."

"What do you two want from me?"

"Well, on the order of Miss Ilea, we are here to protect you and your assistants when they return to the castle."

"What happened over there at the castle?" Li Yu frowned.

Jordi hesitated for a moment before replying, "Maybe... an assassin appeared."
