Section 509
"You are so dirty!"
"If you say this in front of a girl, your conscience won't hurt. If so, please send me a copy first!"
"Sister, hold on!"
"Sister 666!"
…
Facing the ridicule of the audience.
Lu Yu smiled helplessly:
"Brothers, pay attention to the scale. It will be bad if you attract the mythical beast. Let's watch the live broadcast."
"Because next, it will be time to witness the miracle again."
"You may not believe it if I tell you, but it doesn't matter. Today I will let you experience the power of unlocking industrial destiny~!"
These words confused the audience.
I can't figure it out at all.
What does this guy want to do?
Is it possible that we are entering the steam age?
Looking at the barrage of replies.
Lu Yu smiled mysteriously.
No specific explanation was given.
Instead, we sold it out first.
The conversation changed on the spot.
Continuing with the topic just now, I will continue to introduce to you:
"Although the bark of curare wood is soft and easy to sew, it is not easy to make a set of clothing suitable for the harsh environment in the wild."
“It’s better to break it down into bark fibers first.”
"Of course, if you are making a mattress, you don't have to go through so much trouble. Just sew it a little."
"Okay, everyone, in order to save time, let's talk and do it at the same time."
"But before I officially start, I need to build some handy tools. After working on it for so many days, I don't even have a knife in my hand..."
While talking.
Lu Yu left the camp.
Following the wild path, we came to the stream.
Although I now have the "keel" in my hand.
But in comparison, flint is still the first choice for making wear-resistant cutting tools.
Not only is it easy to obtain, it is also very durable.
If the knife from before was not lost.
Maybe until he leaves, Lu Yu will never make stone knives again.
…
Except for the coast.
The only place on the island where flint is likely to exist is at the bottom of the river.
There are large amounts of limestone in the Twin Mountains on the north shore.
Nodular chert is mostly found in limestone.
With the help of changes in the earth's crust and flowing water on the surface.
At the bottom of the stream, various rocks are deposited.
Therefore, the bottom of the river is undoubtedly the best place to find flint.
soon.
After some investigation, Lu Yu found two pieces.
But the texture and shape are not suitable for making knives.
Finally had to give up.
Actually, it’s not impossible.
But if that were the case, polishing would be very difficult and time-consuming.
It's not as satisfying as a stone with just the right shape.
"Although the two stones discovered just now are also flint, their shapes are quite different. The cost of reprocessing will be very high."
"If conditions are limited, it's okay to use it."
"But if conditions permit, it is best to choose a shape that meets the requirements. It can be shaped with a little polishing, and it will be much easier to make."
The reason for discarding the stones was explained to the audience.
Lu Yu immersed himself in searching again.
After a while.
In the end, all the hard work paid off.
Next to a huge pebble deposited on the bottom of the river, Lu Yu finally found the material he was happy with.
It was a piece of nodular flint with a unique shape, hard texture, and a very clear shell-shaped fracture!
Whole stone.
Rectangular in shape.
Wide at the top and narrow at the bottom.
Color deep red.
Holding it in your hand, it is exactly the shape of a knife.
Secondly, the shell-shaped fracture is just right.
Very much like a blade.
The rest is just perfect sharpening.
Wrap with bark rope.
It can be used.
It is definitely a rare piece of high-quality stone.
"See? Brothers."
Stand in the middle of the stream.
Lu Yu looked at the drone camera, waved the rough stone in his hand and said:
"Only this kind of stone is the most suitable. This natural shell-shaped fracture is perfect. It almost saves us the step of making the blank. We only need to grind it a little later."
After landing.
Lu Yu immediately turned around and headed back home.
Soon.
When he arrived at the camp, he walked directly to the stone statue.
Holding the flint stone, find the right angle, and immediately started grinding the horizontal knife.
Because it's the right shape.
Plus the fracture is clear.
In less than half an hour, a decent-looking stone knife appeared in front of the audience.
This stone knife, whether it is shape, texture, or sharpness, is much stronger than the previous generation.
It’s simply a textbook-level stone knife!
"6666!"
"beautiful!"
“It feels like it could be put on display in a museum!”
"Perfect!"
Immediately afterwards.
In order to make it more suitable for grasping, Lu Yu took out an unused thin vine from the storage room.
Tightly wrapped around the handle of the knife.
End with a smooth knot.
It makes the whole knife look much more beautiful.
…
Make a stone knife.
Lu Yu found a stone slab and sat down.
Put the curare tree bark prepared in advance beside you.
Then, I picked one up casually.
According to the vertical growth lines on the bark.
Use a stone knife to tear off the very fine bark fibers one by one.
"These bark fibers are very fine, so you have to be careful when tearing them."
“Don’t use too much force, and be sure to follow the grain, as it is the key to weaving the cloth later!”
