After cleaning up the rotten cloth strips and some gravel in the iron box, Zhou Bo's expectant eyes slowly disappeared.

"Damn, this is the treasure? Are you sure you didn't rob the homeless people?"

Wheath looked at a few black silver coins, the patterns on which were not even clear, only the heavily oxidized outer layer.

Duoduo was also disappointed, in her little head, weren't all treasures shiny? how could they be so ugly? like the poop of the swamp.

Oni didn't quite understand this aspect either, so he just patted Zhou Bo on the shoulder comfortingly, and helped repile the gravel and rocks into the breach.

Zhou Bo sighed lightly and scratched his head a little. It has been oxidized to this extent, which shows that these silver coins have some value, and they must have existed for a long time.

But to remove the oxide on it smoothly, it is not so simple. Unless Zhou Bo wanted to melt the silver, he could easily remove the oxides.

Pure silver coins are worthless, and only rare silver coins of the last year are worthless. And it's not the silver coin itself that is valuable, but the meaning and historical value it once represented.

Zhou Bo groaned slightly, and decided that it was best to wipe it clean after going back. Wash the white toothpaste, wipe it with a soft cloth with soapy water, wipe it with a silver cloth, wipe the silver paste anyway, just see how it works.

Throwing away the tin box and rags, Zhou Bo obtained sixteen silver coins, and although the pattern could not be seen clearly, the treasure hunt was a lot of fun.

After putting away the silver coins, Zhou Bo calculated the time and felt that it was time to go back.

It's been four days since I came out, and I've gathered a lot of wild animals, and the weight on my body is almost to the limit.

A large number of mushrooms, medicinal herbs, and precious plants occupy almost most of the area of Rinlu's body, making Rinlu look like a large moving garden at this time.

In addition to these, those wild animals are also burdened with a lot of harvest. finally came out for a trip, and Zhou Bo can be described as a bumper harvest.

It's a pity that I didn't meet a transcendent creature like a big bear, but I met a silverback orangutan who can juggle, and it was worth the trip.

It took four days to come out, but it didn't even take two days to go back.

Back at the treehouse, Zhou Bo first went to see the progress on the other side of the wall.

Most of the workers have been evacuated, leaving only a few installers who are commissioning the cameras and the grid.

Because the location of the cameras and the power grid has been thought out for a long time, the overall look is very discreet and safe.

Not to mention the camera, unless you deliberately look for it, it will basically not be easily discovered. This not only guarantees the safety of our guests, but also respects the privacy of others to the greatest extent.

The power grid is more dangerous, so when it was first designed, Zhou Bo thought of using something to cover it.

It was planted directly on the fence with some tall artemisia grasses, which were more than two meters high, and the power grid would be about the same height, just enough to faintly block the power grid.

Although there are still traces of the power grid in the gaps, it is much better than the bare power grid.

There are no places to climb or settle on the fence, which ensures the safety of visitors, especially those who like to climb high, without touching the dangerous power grid.

The walls are almost dry, with a light white base painted on them, and the rest of the walls are blank, waiting to be painted.

This is also the method that the employees came up with, and Zhou Bo agreed after thinking about it.

Although I can paint a lot of verdant patterns on this wall, I always feel that some traces of deliberate and carved are a little heavier.

Then Zhou Bo took the advice of the staff and simply left the painting in this position blank, so that the guests could buy a piece of area on it at their own expense, and paint whatever they wanted.

In this way, although it is a bit messy, it fits the casual theme of the casual treehouse.

Since it's leisure, tourists definitely don't want to see things that are too regular and stereotypical, isn't coming here to get rid of those bad lives and stereotypical jobs?

After the wall was built, it can be said that the whole is very satisfied. In addition to the location of the gate and the back door, there are four very large gaps in the entire wall.

Four very large gaps, certainly not engineering problems, but changes in the scheme before construction.

Each of the four notches is more than 10 meters long, which was deliberately left behind after consideration and deliberation.

If the wall has been built, why leave a gap? This is also one of the suggestions from the employees.

Some of these employees have experienced this kind of work place before. It is almost completely enclosed, giving a very oppressive feeling.

This is not a prison, and the fence was built for security.

After all, it is also Zhou Bo's private territory, and it is easy to attract the incident of Wang Mingwei and his son last time if it is so open.

At the same time, it is impossible to watch the live broadcast from the treehouse all the time, so at night, the fence can give people a strong sense of security.

So how to give people a sense of security, but make the whole leisure treehouse seem less depressing?

These four large gaps set aside are the solution.

In fact, it is very simple, the tall fence is oppressive, and that is because the wall hinders the transmission of vision. If it's in an open place, you won't feel depressed. Even in the face of a thick piece of tempered glass, it will not feel oppressive.

So Zhou Bo's method is to replace the fence with tempered glass with a thickness of ten centimeters on these four large gaps.

Four large gaps divide the entire treehouse into an average of six. The fence makes people feel safe, and the large area of tempered glass can make people less oppressive and even full of fun.

Zhou Bo even thought about using only tempered glass, but in the end he rejected the proposal.

The simple use of tempered glass, whether in terms of hardness or protection, is much better than the fence. Although the cost is a little high, it is also within Zhou Bo's affordability.

The reason why tempered glass is not used is that there is a need for a support point and a sense of security.

Only tempered glass, reinforcement and fixing are a problem. Even if it is fixed, the price of such a high tempered glass fixation may be higher than its cost.

And all of them are tempered glass, although it will make people shine, but there are always some hidden dangers that are not very safe.

After all, this is a forest, not a high-end 4S store that sells cars, and simple tempered glass is not suitable for a casual tree house.
