After discovering so many precious tree species, Yu Shan looked at the problem from a different angle, because he suspected that these tree species were specially planted by someone. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The reason for this idea is that the distribution of these tree species is so regular that it does not look like they grow naturally.

After a few days of exploration, Yu Shan knew that the most common tree in that forest was iron birch, which was known as iron sandalwood, and the wood could be so solid that the bullet hit the tree, just like hitting a thick steel plate, and it didn't move at all.

Its wood is three times harder than oak and twice as hard as ordinary steel, so it can be used as a substitute for steel in the defense industry.

Because it is very hard and heavy, it sinks immediately when it enters the water, and the inside of it can remain dry for a long time even if it is immersed in water for a long time.

It can be said that this is another tree species that can be compared to thorn oak, and there are many more than thorn oak, of course, in addition to these species, there are also some very hard tree species.

And if those tree species are placed on the earth, all belong to the cherished tree species, some time ago, Yu Shan purchased beeswax, but wandered around the antique market for a long time, so for those people who play wood in the cultural play, but very well understood.

For people who play wood, it is mainly divided into three kinds of people, one is to play with color, that is, the pattern is beautiful, the color sense is beautiful, generally sea yellow, the more yellow and the like; the other is to play with incense, such as red sandalwood, old sandalwood, etc.; There is another kind, which is to play "hard", that is, density, what's so fun about this?

The greater the density of the wood, the more crystalline the texture after its pulping, and the crisper the sound of gold and stone when it collides.

Iron birch, the hardest in the world, will not be mentioned, and the golden camphor will not be mentioned, but some not very well-known, such as a piece of sand and land that they passed by in Yushan just now, this kind of land is like a desert, so some special trees grow on it, desert ironwood.

Listening to its name, the hardness can also be felt a little, this kind of wood is also found on the earth, but it does not grow in China, it grows in the desert from the southwestern United States to the northwest of Mexico.

This kind of tree, known as desert ironwood, grows very slowly, and it takes 100 years to become a timber, so the hardness is particularly high, reaching 1.2 grams per cubic centimeter, and the nature is extremely stable, and it is generally used for high-grade knife handles.

Then there is the small-leaved red sandalwood, about this, because everyone is too familiar, not to say much, its density range is generally between 1.2-1.5, and the mahogany standard even makes this one of the important criteria for judging the authenticity of the small-leaved red sandalwood, that is, as long as it is small-leaved red sandalwood, its density is within this range.

Under normal circumstances, the density of new materials is mostly about 1.2, the density of old materials is mostly about 1.3, and the density can reach 1.5 for less materials, and it must be the best top old red sandalwood material.

These trees are more conspicuous and easy to recognize, so Yu Shan knows them very well.

And as you get closer to the forest over there, as long as you have the heart and pay a little attention to the trees under the airship, you can find one or several kinds of precious wood.

For example, now, the third kind of tree they encountered in Yushan was the pear pimple, and the place where they grew was a hillside, but this was a rocky hillside, and there was hardly much land, and it was in such a bad environment, but there was such a forest, so it was very abrupt, and when they saw it, they were noticed by Yushan.

During this period of time, although Yu Shan did not move, the fifth knife and Huang Da were sitting in the airship, but they were not less wandering around, and it was at this time that they collected all the surrounding situations.

Same as desert ironwood, the growth environment of the pear pimple is also harsh, it grows in the perennial water shortage area, so the growth is also quite slow, but its texture is quite hard, the color is warm and moist, some roots appear nodulous, the wood grain is rich, it is resistant to fire, it sinks in the water, there is no miscellaneous smell, and the nature is also extremely stable.

The hardness of the pear is comparable to that of red sandalwood, and even surpasses it, and the pipes and handicrafts made of it are loved by people and can be played for a lifetime.

Continuing closer to the forest, more and more trees appear, and the third most abundant is the black sandalwood, which has an air trunk density of 1./cubic centimeter, making it one of the hardest woods available today.

The heartwood of black sandalwood is dark purple-brown to nearly black, with black stripes, its cut surface is smooth, brown eyes are scarce, the texture is tight, the oil is heavy, and the wood grain is clear and varied, which is called "the wood of the emperor".

In particular, the surface has a satin effect due to its high density, and the light is very beautiful.

When I saw the forest, on the outskirts of the forest, some low jungles, all serpentine.

Serpentine, small crown tree, no roots, 25m high, 15m trunk, 30-50bm diameter, this tree species is the world's densest wood, up to 1.36.

The heartwood of serpentine wood is clearly distinguished, the sapwood is wide, pale yellowish-white, and the heartwood is dark reddish-brown, and the formation is extremely slow.

The pattern is changeable, similar to snake pattern, hieroglyphs, and English letters, so it has the reputation of serpentine wood, letter wood, and oracle bone wood, and has a very decorative effect.

There are so many good woods, several of which appear within a range of forty kilometers not far from the mountains, if it is accidental, it is really unconvincing, so when doing something, Yu Shanyan has a little more scrutiny.

"Shall we go collect the hearts of the trees first, or shall we go up the mountain first?" Arriving at the periphery of the Giant Tree Forest, looking at the continuous forest, Fifth Knife asked.

"Let's go into the mountains! Enhance the strength first, and then the resources here will be collected as we like. Yu Shan waved his hand and gave an order.

Although he did not enter the forest, Yu Shan could still see the situation inside the forest very clearly.

Although there are not many animals because the trees are too dense, it does not mean that the forest is safe.

You must know that the terrain in the forest is more complicated than in the sea of grass, and in such a place, it is easy to be attacked by fierce beasts, so even if there are not too many groups of fierce beasts, it is not a good place.

The view on the mountain is also broader, and if you choose the right destination, safety will be more guaranteed.

"This is where you used to be?" Looking at the undulating peaks in the distance, Yu Shan asked.

Between the peaks, there are sometimes large areas of buildings, but these buildings are so badly damaged that most of them are left with ruins.

Huang Dadao: "Yes, this is it, this is more complicated than what we see now, have you seen those buildings?" The exposed buildings have actually been excavated and can be occupied, and hidden in the mountains and valleys, there must be undiscovered buildings, and those are the real treasures. ”

"So many complexes, and not all of them?" The fifth knife said in surprise.

Huang Dadao: "Looking at the topography here, especially the buildings in the mountains, is it very unreasonable? In addition to the distribution characteristics of some buildings, should there be buildings in some places?

But there is a blank space, or a dense forest, or a canyon, and some people speculate that there are hidden buildings there, but they can't find it, maybe it is not the time to be born. ”

Yu Shan nodded, this speculation is correct, if this is the residence of a large sect, then they should build a sect station, and its building distribution should be regular.

For example, the building where the mountain gate is located looks very incongruous, especially some things that are exposed like door posts, no matter how you look at them, they are only half of them.

And the other half is definitely on the other side, but there's nothing over there, so it feels weird to look at it.

There are also several peaks on the mountain, and there is often a group of buildings on the peaks around them, but the few peaks in the middle are covered with clouds and mist, and it is impossible to see what is on them, which is obviously unreasonable.

Of course, halfway up each peak, or some flat places, plus some places with strong aura, there will definitely be buildings or spiritual fields, but now, the buildings and spiritual fields in some places are exposed, and there are some peaks that are not exposed, which all speaks volumes.

"There are a lot of beasts in the mountains?" Yu Shan asked.

Huang Da was silent for a while before he said: "If calculated according to the area of this mountainous area, the number of fierce beasts is not too much, and it is even rare, if you simply count the number of fierce beasts, then it is a lot." ”

"Look there, that's where we intend to occupy." At this moment, the airship flew over the peaks and came to a small peak hidden among the many peaks.

The peak is not very high, but it is thick, and from a distance, it looks like a valley with a platform suddenly growing, so that there is a large flat area on this peak, and the connection between it and the surrounding peaks is also very gentle.

This place is the center of the entire ruins, so the buildings are dense, and when you look at it from the air, it looks like a nine-square grid below, and there are ancient remnants of buildings everywhere.

I don't know how many years the buildings have existed, and they look very old, but many of the buildings still have remnants of the walls, so the terrain here has become very complicated.

If you look at it from the air, you can still tell the direction, but if you enter it, it will definitely be more troublesome than the maze.

"There are probably the ruins of the main hall of the ancient sect here, and only the buildings allow us to easily spot the enemy, so it is very suitable for us to explore." The Fifth Knife Path.

Yu Shan nodded, acknowledging this place, and it could be seen that it was composed of courtyards, or palaces.

And each palace is independent, with mountains, waters, fields and land, of course, the most conspicuous are those lonely but towering trees in the courtyard.

Seeing these big trees, Yu Shan's heart moved and asked, "Huang Da, when you come in, you won't appear directly in front of the outer trees, right?" (To be continued.) )
