Blackstone is not so much a town as a large lake, and there is a ring of land around the lake that separates it from the entire body of water in the Crystal Palace, and the surrounding land is the so-called Blackstone Town, and the large lake around the town is Blackstone Lake.

Blackstone Town is far away from Shishui City, which can be said to be a remote area in the Crystal Palace, but Lin Zhuowen unexpectedly found a prosperity here that is no less prosperous than the Crystal Palace, because this Blackstone Town is rich in a kind of black spirit stone, which is one of the few important sources of spirit stones in the Crystal Palace, so there are not only soldiers stationed here all year round, but also a lot of business trips, and those with good quality of black spirit stones produced here will naturally be sent to Shishui City, and those with poor quality have become the objects favored by business travelers.

The Crystal Palace is self-contained, isolated from the outside world, and is self-sufficient, but after all, the territory is limited, even if it is blessed, there will inevitably be a shortage in some aspects, this spirit stone is one of the very strong shortages, although the natural spirit stone deposits in the Crystal Palace are not nothing, but they are indeed limited, and the reserves are limited and scattered, although they have tried their best to excavate, but the spirit stones produced every year are still limited.

However, the Crystal Palace also has its own advantages over the outside world, that is, this Black Stone Town, to be precise, it should be a creature in the Black Stone Lake in Black Stone Town, a magical shell called the Black Stone Shell, this kind of shell is three meters long as the adult body, oval shape, and the whole body is dark, the most amazing thing is that the Black Stone Shell has been pregnant with a small stone in the body since birth, and with the growth of the Black Stone Shell, the size of the small stone will also increase. Until the black stone shell becomes a mature body, the small stone in its body will also be the size of a baby's fist, which is the black stone.

The black stone contains aura, compared with ordinary spirit stones, not only the amount of aura is a lot, but also because it is conceived in the body of living beings, so the aura contained in it is more pure, easy to absorb and refine, this is the so-called black spirit stone, rough sound. This seems to be about the same as cultured pearl oysters to get pearls. Lin Zhuowen originally thought that this was the case, so he regarded this Black Stone Town as a novel tourist attraction, wanting to see this otherworldly version of the spirit stone breeding industry with his own eyes.

In the Crystal Palace, Blackstone is an important place. The garrison shows the importance attached to this place in the Crystal Palace. However, with the token given by Biyu Xiaolongnu. Lin Zhuowen was able to get in and out smoothly and did not suffer any trouble, but when he saw the so-called spirit stone breeding industry with his own eyes. He regretted it a little, since it was a similar pearl oyster breeding industry, then it was inevitable to kill shellfish and take stones, which Lin Zhuowen had already thought of, but he never thought that it would be such a scene.

The black stone must be picked after the black stone shell becomes a mature body, otherwise the quality of the black stone obtained will be affected, and it will become a defective black stone, the defective black stone is not only small in size, but also mixed with some red blood on the surface, and the strict zhòng person is like the internal organs forcibly removed, such a defective black stone will contain much less spiritual power than the normal black stone, and there is still part of the blood of the black stone shell, affected by the attributes of the black stone shell, it will be more troublesome than ordinary black stone in absorbing and refining.

But there is a contradiction, this black stone shell is born with great wisdom, the mature body of the black stone shell has quite a lot of wisdom, although can not talk about people's words and deeds, but the simple pursuit of advantages and avoid disadvantages is known, born slow action, can not leave the black stone lake, but will not lead the neck to kill, those shellfish people every time they pick shellfish is like a battle, must hold a sharp magic weapon to dare to go into the water, and every time there must be a fight, the waves are numerous, and the final black stone shell is often broken shells, flesh and blood are blurred, lose the ability to resist action。

The steward here may regard Lin Zhuowen as a messenger sent by Biyou, so when Lin Zhuowen asked to visit the shellfish picking site, he did not object, and after arriving at the place, he also deliberately took out two newly taken out black stones to give to Lin Zhuowen, these two black stones are in good condition, after washing with water, there is no red blood on the surface.

Lin Zhuowen frowned and took it, he is not a righteous gentleman, in this world of cultivating immortals, he also understands that any sympathy is superfluous, but he never thought that there would be such a large-scale massacre, the black stone is actually more like an important internal organ of the black stone shell, the black stone shell that was dissected and took away the black stone shell, it was like being removed from the heart and liver, only the wailing and waiting for death remained, Lin Zhuowen was not sure if the very low and long grunt was the wail of the black stone shell, but he couldn't think of what else it could be besides a wail.

The two black stones were in my hands, and I felt them carefully, there was still a bit of life in them, and there was a hint of fleshy softness, but with the passage of time, this warmth and softness were also being quickly withdrawn from them.

"If the black stone in this black stone shell is not taken out, what will happen if it is allowed to continue to grow?" Lin Zhuowen couldn't help but ask.

"If it is allowed to continue to grow, it can naturally breed higher quality black stone, it is said that someone has obtained the best black stone from the thousand-year-old shell, and the utility value is more than the upper grade spirit stone. "The one who answered Lin Zhuowen was a turtle man, and the steward of Blackstone Town was a crab man, five big and three thick, and a crab shell was like a general wearing armor, and this turtle man was a subordinate of the crab general, I don't know if it was a staff member or a military advisor, and he was arranged to entertain Lin Zhuowen.

The turtle man's name is Shou Younian, although the turtles are long-lived, but this Shou Younian is still young, although the appearance is different from that of humans, but Lin Zhuowen looks like smooth skin, straight eyebrows and beardless, placed among the turtle people, that is, a young man, but his eyebrows and eyes are upturned, and he has a smile that greets and flatters.

"Then why don't you let these black stone shells continue to grow? Wouldn't it be better to get better quality black stones?" Lin Zhuowen asked.

"I don't know what to do, the slower this black stone shell grows later, although the quality of the black stone bred in it will also improve, but this process is also very slow, and not all black stone shells can continue to advance with the accumulation of time, although the millennium black stone shell may be equivalent to the black stone of the upper grade spirit stone, but more are only equivalent to the middle grade spirit stone, or even the lower grade spirit stone, compared with the millennium time, these harvests seem to be somewhat worth the loss, so it is the most cost-effective to take the stone directly after the black stone shell is mature。 Shou Younian paused at this point, and added: "Moreover, the adult black stone shell already has a lot of wisdom, fishing is already very difficult, if it is allowed to continue to grow, the difficulty and danger of fishing will increase exponentially, the thousand-year-old shellfish is said to have great ability, if there is no strength in the Jindan period, let alone fishing, it is difficult to get out of the whole body."
