After encountering the Sandstorm Brute, Xu Zhen and the others' spaceships encountered several more dangers, but they all survived without danger with the concerted efforts of everyone.

After three days, the sky finally changed, and the horizon was no longer a static sight, and a black line appeared. Xu Zhen, who wanted to vomit after looking at the yellow sand, leaned on the window and looked at the black horizon in the distance, in the distance was a black area, and he had nothing to do in the past few days, and he also learned about the situation of the Su family's black stone sea.

The Sea of Blackstone is not really an ocean, it is just full of stones called obsidian, which is why it is called the Sea of Blackstone. Obsidian is a necessary material for city and base construction, and obsidian is also divided into multiple grades, the purer obsidian the better the energy resistance, the stronger the building, and the origin of obsidian is the most famous for the sea of obsidian, where the amount of obsidian minerals is not only huge, but also extremely high.

But this is controlled by the forces of Black Yao City, as the most powerful force in the Black Stone Sea, the Su family, it is natural to master the way to buy and sell obsidian, and with the help of this way, a lot of benefits have been obtained, and a family has been established. Although the Su family is a family, it is still too weak compared to those mysterious families inherited from ancient times, although the money is enough, but the strength is far from keeping up with the speed of wealth accumulation, and the interests of the Su family have been lost, so they need a strong man to support them.

But the strong are not so easy to make, with enough money, the children of the Su family can easily reach the seventh level, and have many things that are difficult for others to get, but the most powerful person in the family is only the strength of the tenth level, which is far from enough to hold this huge foundation. Therefore, Su Mutian and the others got the news of the fire spirit marrow to receive so much attention from the family, if it weren't for the fact that the distance was too far, they would have sent someone to rescue the person themselves.

Theoretically speaking, although the obsidian minerals in the Sea of Blackstone are huge, they should not be able to attract the attention of those big forces, but recently the Holy Temple seems to be researching what kind of obsidian giants, and it needs a huge amount of extremely high-quality obsidian, if it is purchased with money, it will cost a lot of money, and it is better to have a high-quality obsidian mining area yourself. But there is only one obsidian mining area in the Sea of Black Stone that can meet their requirements, and the Su family has benefited from this mining area, how can they hand over this mining area.

As a very commonly used building material, obsidian is strictly controlled by the council in price, and some obsidian of ordinary quality can only be used as building materials The profit is very underground, only those high-quality obsidian, and other functions, are not controlled by the parliament, there are great profits. According to the rules of the system, people who discover the mining area can hand over the system and get a large number of rich rewards, or they have the right to mine for a period of time, the mining right is calculated according to the richness of the mining area and the strength of the discoverer, the richer the strength, the stronger the longer the time to own, when the ancestor of the Su family discovered the sea of black stones, he obtained the mining right for ten years.

And ten years of mining time has passed, but the strength of the ancestors of the Su family is stuck at the tenth level, and it is impossible to go further, and the Holy Hall also has a chance to intervene, in order to find an opportunity to break through, the children of the Su family are running around, looking for those rare heavenly and earthly treasures, but unfortunately with little success, until Su Mutian sent back the news that someone had found a fire spirit marrow mine, which caused the shock of the family.

After flying into the Sea of Black Stone, you can see some stone giant-like monsters active on the ground, and those monsters are also the round shape of the obsidian giant that the Holy Temple will develop, the Black Rock Monster. The spaceship didn't stay too long, and flew all the way towards the depths of the Black Stone Sea, Xu Zhen saw that there were many people on the ground hunting Black Rock, but it was usually a few people who teamed up to deal with one.

The body of the black rock beast is very strong, and the resistance to energy is still very high, it can be said that it is a very difficult monster to deal with, but they have a very valuable material in their body - high-quality obsidian. These obsidian stones will eventually be purchased by the Su family, transported to farther away to be sold, and sold at a high price. However, recently, people from the Holy Temple have purchased these scattered high-quality obsidian stones in Heiyao City, and there has been a conflict with the Su family.

A city appeared on the ground, and the city was completely made of black rocks, this is Black Yao City, which has extremely high defense power, and can easily resist energy attacks below level 12, which can be said to be indestructible. The tall city walls protect the people inside from the attacks of those black rock beasts outside, and this is also the base camp of the Su family.

Su Mutian's spaceship did not fly in from the city gate, but flew directly into the air, and the crowd on the ground was also surprised when they saw it, and there was no reaction. The ship passed over a number of low rock houses and came to a place that resembled an inner city, with even lower walls, and the houses inside looked much taller than the outside, and the ship landed directly on the large square of the inner city.

When Xu Zhen and the others got off the spaceship, there were already many people in the square, and the leader was a middle-aged man who was somewhat similar to Su Mutian. He greeted him and walked directly to Xu Zhen, "This is Xu Zhen's little brother!" What a young man! Su Xuan walked over, stretched out his hand and shook hands with Xu Zhen and said. Most of the people present were middle-aged, and the young ones basically didn't see a few, and through Su Mutian Xu Zhen also learned that the juniors were sent out to find their own opportunities, and they rarely stayed in Heiyao City.

"You're polite, you're polite, it's not about being young and promising." Xu Zhen also replied politely.

Su Xuan was also an old man, and said with concern: "Little brother Xu Zhen has been gone for so long, he must be very tired, I have prepared a banquet, let's go to eat first, and then talk about other things after eating!" ”

Su Qingyu pouted and said, "Hmph~ Dad's eyes only have Xu Zhen's little brother, and he doesn't even look at his own daughter." Su Xuan laughed, "My little herring, I still eat Xu Zhen's vinegar!" Okay, okay, your mother is waiting for you at home, she heard that you are in danger and has not been able to sleep, why don't you go back and see your mother quickly. Su Xuan touched her head and said.

Su Qingyu took his hand away and said, "I'm not a child anymore, don't touch my head all the time, I'll go back to see my mother first, you go to dinner!" After speaking, Su Qingyu made a grimace and ran out of the crowd. Su Xuan was also a little crying and laughing, "This girl, she really doesn't grow up!" ”

Seeing Su Qingyu talking to his father, Xu Zhen was a little stunned, how long had he not talked to his father, as if it was four years ago. He was slightly stunned, but he quickly came back to his senses and kept up with Su Xuan's pace, and Hu Xiaobai also followed closely behind Xu Zhen.

After a few people in the crowd saw Xu Zhen, they exchanged their heads and whispered, as if they were discussing something, but soon they stopped and followed Su Xuan towards the Su family's welcome hall.

When he arrived at the welcome hall, Su Xuan sat in the first place, Xu Zhen originally wanted to find a random seat to sit down, but Su Xuan invited him to sit beside him, Xu Zhen couldn't refuse his kindness, so he had to sit down, and Hu Xiaobai also sat next to him. The few people who walked in behind saw that Xu Zhen and Hu Xiaobai were sitting in the seats, their faces changed slightly, and after thinking about it, they still didn't say anything, and sat in the lower seats.

On the other side of Su Xuan, he was a middle-aged man who looked about the same as Su Xuan, who should be his own brother, and at the wine table, Su Xuan didn't talk about the cooperation with the Su family, so he chatted with Xu Zhen, chatting very easily, and eating was also very satisfying. After eating, Su Mutian took Xu Zhen to a two-story campus, which also planted a lot of plants, this is where Xu Zhen and Hu Xiaobai rested, seeing that it was late, Xu Zhen was also a little sleepy, and he was a little tired, so he said hello and left.

Xu Zhen retreated from the door and entered, inside was a living room, which looked similar to the ancient hall, with two chairs on top and a small table in the middle. The room was a little dark without turning on the lights, Xu Zhen touched it for a long time before he felt a switch, the light turned on, and the room immediately became bright.

After going upstairs to take a look, he told Hu Xiaobai to go upstairs to sleep, and Xu Zhen sat on the seat in the hall in a daze. I drank with Su Xuan just now, and I was a little dizzy, but at this time it had returned to normal. Looking at the cold lights inside the house, it seems that the outside of the house has become very dark, and I can't see anything clearly.

Although he didn't talk about anything about cooperation with Su Xuan during the meal, Xu Zhen still felt that it seemed that someone didn't want to cooperate and share the benefits with him, but wanted to swallow it alone. I just don't know what Su Xuan's thoughts are, he has already seen that if he doesn't have the strength, it is likely that when he tells the secret, it will be his own death. Xu Zhen sensed from their expressions the value of the Fire Spirit Essence far more than he estimated, and the huge profit was enough for the Su family to be tempted to swallow it alone.

He thought about it, clicked out his badge interface, entered the lottery system, and drew the reward from the last Flame Hell dungeon. Xu Zhen's consciousness appeared in a huge space, and a disc appeared in front of him, which was densely covered with an unknown number of things, and it seemed that there were more lottery rewards than the Wangcheng copy.

The disc rotated rapidly, the pointer stopped on a grid, and a thing appeared in Xu Zhen's hand, and seeing the brief introduction of this thing, Xu Zhen's somewhat hanging heart finally let go. It was late at night, and only the first floor of the small courtyard was lit, and the light looked a little lonely.

In the middle of the night, Xu Zhen, who was sitting on a chair, suddenly heard something, opened his eyes, and found that Hu Xiaobai had walked down, "Xu Zhen, I can't sleep." Looking at Hu Xiaobai who walked in front of him, Xu Zhen was also a little speechless, you told me that you couldn't sleep in the middle of the night, you have the habit of recognizing the bed!

"I want you to sleep with me, and I can sleep with you in my arms." It was late, Xu Zhen didn't want to toss anymore, so he sent Hu Xiaobai back to the room, and fell asleep directly on the bed. When he slept in a daze, he felt as if he had caught something, it was soft and comfortable, and in the middle of the night he had an indescribable dream......
