However, Lin Yi still carefully checked these small leaves of red sandalwood, after all, ten sandalwood and nine emptiness are not a joke.

The "sandalwood" in "ten sandalwood and nine emptiness", we refer to the red sandalwood of the wild forest, and there is also a saying to explain that it is "one zhang of sandalwood and nine feet empty", no matter which way it is said, it expounds the hardships of red sandalwood. Because the wild forest of red sandalwood grows in the mountainous area with a complex environment, the land is not fertile, and the maturity cycle is hundreds or even thousands of years. Due to the harsh growth environment, the tree poles will bend, resulting in irregular textures and uneven grain thickness. It is said that it takes 800 years to grow to a diameter of 20 centimeters, and the wood is oily and sinks when it enters the water. The extreme lack of nutrients leads to the fact that in order to protect itself, the red sandalwood itself will slowly absorb the nutrients of the heartwood, causing the part of the red sandalwood close to the heartwood to become more and more soft, until the nutrients of the heartwood are completely absorbed, and then the chaff, white, and finally become "dead sandalwood", and the oil is also exhausted, like sawdust. We are the same, when we are hungry, our hearts are empty, and there is a common saying that "hungry hearts panic". We sometimes see red sandalwood handles without brown eyes, which are made of this material. If it is not adopted in time, it will slowly corrode away and eventually disappear. In short, the harsh environment is the inevitable reason for the creation of "ten sandalwood and nine emptiness".

But fortunately, in Lin Yi's eyes, the hearts of these small-leaved red sandalwood trees grow very well, and there is no hollow condition at all.

However, the attention now is not on these small-leaved red sandalwood, but on those agarwood trees.

He also searched the Internet for information on agarwood. The woody heart of the agarwood tree is called agarwood after drying, although the price of this wood is not cheap, but Lin Yi is not eye-catching.

This is the lowest and can only be called agarwood, not agarwood.

Agarwood is knotted in the agarwood tree, but a healthy agarwood tree will not produce agarwood out of thin air, and must be traumatized under certain circumstances, such as being injured by lightning, strong wind blowing, or animal and insect bites, artificial felling, etc., out of the plant's instinct will secrete resin (also an antibody) to make up for the wound.

During this period, the wound of the agarwood tree happened to be infected by a microorganism called the yellow-green fungus, which will do adversity metabolism in order to survive tenaciously in the tree, which is a wonderful biochemical reaction process.

The antibodies of the tree itself and the yellow-green fungus and other substances that invade the tree are mixed together, and gradually a compound called "benzylacetone" is produced, and with the deepening of the biochemical process, sesquiterpenes and chromoketones are formed, and the product of the mixture of these two types of compounds is called "agarwood".

It can also be said that agarwood is a resin secreted by agarwood that is invaded and parasitic by fungi and begins to resist invasion by itself, which is equivalent to an "immunity" resistance process of the tree itself, and then a complex that has been deposited over many years.

It does not belong to wood or fungi, it belongs to the marginal disciplines of wood and mycology, similar to Cordyceps.

The production areas of agarwood are mostly island countries such as Southeast Asia and the Indian Ocean, and the growth period is mostly 100~1000 years.

There are usually three external triggers for the formation of agarwood: one is that it is eaten by insects, causing the trees to gradually die, and the agarwood formed in this way is called "insect leakage", or "ant sinking".

Then there are natural disasters, such as lightning strikes, mudslides, landslides, etc., which cause trees to break and then be buried by soil or flooded by swamps, the former is called "soil sinking", and the latter is called "water sinking".

If there is no natural disaster, then the inverted frame is also counted, the agarwood tree is broken by animals or people during the growth period, and then buried by the soil or flooded by the swamp for a long time, the agarwood formed is also called water sinking or soil sinking.

If the agarwood encounters the above three conditions, it begins to produce agarwood, but the tree does not die, but continues to survive, and later the part that produces agarwood is mined, this type is called "live sinking or raw knot".

On the other hand, if the tree has been mellowed for enough time after death, it is called "dead sinking." maturation".

"Inverted frame" belongs to the dead sinking, which is the incense of the tree after death, and the hundreds of thousands of years of rain that pass through the original place, and finally become extremely fragrant.

Because of the incense, the agarwood itself does not rot.

In the classification of agarwood, the price of agarwood is the lowest, and among the rest, the price of dead and heavy is higher than that of live sinking under the same quality.

After the formation of agarwood, the resin content of a piece of agarwood represents the quality of the quality, the higher the resin content, the less wood content, then the higher the quality, and even there is a complete resin aggregate, which is the best in the growth, and it is also the most precious agarwood.

However, because it is very difficult to find agarwood in the wild, sometimes even if you cut down the tree, you will not find a trace of agarwood, but you will lose such a large tree.

Recently, some people have also started to plant agarwood trees, and artificially injure the heart of the tree to promote the appearance of agarwood in agarwood trees. However, the growers use iron tools to pierce the heart of the agarwood tree, which is convenient, but the quality of the agarwood produced is very poor. Not only is it small in size, but also has a lot of impurities. It can't be compared to wild water agarwood at all.

Lin Yi wants to take the high-quality route, so of course he wants to cultivate the best agarwood, and naturally it is impossible to use such a crude method. He also thought about this problem for a long time, and finally came up with a solution - to use the agarwood tree itself to hurt the heart of the tree. Because the heart of the tree is damaged by the exact same wood. In this way, there will be no other impurities in the agarwood, and a large volume of water agarwood can also be formed, which is in line with Lin Yi's requirements.

Lin Yi looked at these agarwood trees, the environment in the Five Elements Beads is extremely suitable for biological growth, now all the agarwood trees have grown new branches and leaves, and a few agarwood trees planted in a few days have grown luxuriantly, as if they have been planted for hundreds of years, and it is impossible to see that it has been planted in the Five Elements Beads for less than a week.

"Let's start, come on!" Lin Yi secretly cheered himself up, and then with a wave of his hand, he cut a relatively thick branch from the agarwood tree in front of him.

Next, Lin Yi used a knife to peel off the outer skin of the branch, leaving only the white part of the heart. Not to mention that the agarwood tree really lives up to its reputation, the white heart of the tree has just been exposed to the air, and Lin Yi smells a fragrance.

A faint aroma wafts through the air. Although it is not as strong as the perfume smell of some women, it is absolutely impossible to ignore. As soon as the aroma entered Lin Yi's nose, it lifted his spirits. Lin Yi has never studied perfume, but he has to admit that the fragrance of agarwood is indeed very good.

In fact, there are several kinds of agarwood trees, and Lin Yi bought the best one among them, so just the fresh woody part will have an obvious fragrance. The quality of the water agarwood produced by this agarwood tree is naturally higher, which just meets Lin Yi's requirements.

Slowly, the core of the twigs is cut into extremely thin pieces of wood, and the two-finger-wide chips are almost translucent. Even so, Lin Yi was still not satisfied. He carefully worked on the edges of the chips with his knife until they were almost as good as razor blades, and then nodded in satisfaction.

"Try it. Lin Yi looked at the wood chips in his hand and muttered to himself. Judging by the tone, he wasn't very sure about what was going to happen next.

Holding the wood chips with his thumb and forefinger, his expression became more and more serious, and he stood in front of the tree with his eyes slightly closed, feeling the texture and weakest parts of the trunk with his heart. After standing quietly like this for a few minutes, Lin Yi's eyebrows suddenly moved, and the wood chips in his hand stabbed at the trunk of the tree like a sharp sword.

In this stab, Lin Yi also used all his strength, and the speed was already faster than the limit of human eyesight. With a flash of white light, the wood chips had already touched the bark of the agarwood tree, and then without even making a sound, they were cleanly broken into several pieces.

"Oops, failed......" looked at the broken pieces of wood on the ground and whistled softly. However, instead of showing surprise or disappointment, he began to cut another piece of wood from the remaining branches.

Lin Yi's plan sounded perfect, using the wood of the agarwood tree itself to hurt its heart, so that the water agarwood seed generated would not have any impurities, and the quality could be improved a lot. However, there is a fatal problem in his plan, that is, how to use wood to hurt the heart of the agarwood tree.

The method that Lin Yi came up with was to use an extremely thin piece of wood and use his strength and speed to stab directly into the tree. Although this method is theoretically feasible, as long as the speed of the wood chips is fast enough, and the angle of the moment the wood chips pierce the tree body is vertical enough, it can indeed pierce deep into the tree, but this requires extremely high speed and angle, even if the wood chips are a little off or slightly twisted, or not fast enough, it will definitely be a broken end. Lin Yi had also been prepared for this, so he was not surprised or discouraged after the first failure, but was soon ready to start the second attempt.

This time, I learned the lesson of the last time, and cut the wood chips wider, so that the front end was as sharp as before, and the back part was thicker. He looked at the freshly cut wood chips with satisfaction, then stood in front of the tree as he had done before, feeling the textures and weaknesses inside the trees, and finally stabbed the wood chips with a loud cry.

The wood chips pierced the bark with a sharp wind sound, but this time the result was worse than the last time, and the wood chips shattered and scattered all over the ground as sawdust. However, he was as calm as before, he carefully observed the sawdust on the ground, and then nodded lightly and said, "Hmm...... It's better than just now. ”

Suddenly, he patted his forehead and realized that he was so stupid, that he could do everything in this space.

With a wave of his hand, countless pieces of wood appeared around the entire tree, and then they stabbed into it, easily and without any problems at all.

He also planted the remaining trees.

But it seems that he has planted too much, and if this continues, more than half of a tree will grow agarwood.
