Family Cultivation: I can upgrade my magic weapon

As a third-level lower-grade magical weapon, the Liuguang Boat can travel nearly ten thousand miles a day.

The group has been flying towards the southern part of Huangsha Island. If they fly straight in this direction, they can reach the Mermaid Sea.

Fortunately, the Haixin Crystal Ore Vein is still within the scope of the Boundary Sea, and there is still a very long distance from the Mermaid Sea.

Otherwise, such a precious fourth-level ore vein would also be controlled by the Mermaids and used to mass-produce tridents.

In the vast blue sea, the sea and the sky are the same color, and the air is full of salty and humid ocean breath. From time to time, small waves are surging, breaking the tranquility of this sea area.

Under the defensive light curtain of the flying boat, the strong wind generated by high-speed flight was completely blocked. The flying boat was flying over the sea like a stream of light, and the surrounding scene was rapidly receding.

Shui Wuyan and the other two were very alert, paying attention to all the slightest movement around them, even a wave would be paid more attention, for fear of encountering strong winds and space cracks.

This is a habit developed from living in the sea for a long time. It is almost a conditioned reflex. They are very afraid of natural disasters here.

Fortunately, everyone had a smooth journey. In almost one day, the flying boat traveled more than 9,000 miles.

When flying to an endless sea ahead, Shui Wuyan relied on the guidance of the fixed star disk in his hand to determine that he was close to the destination.

With the help of the mark left on the sea heart crystal vein, it was connected with the fixed star disk.

Shui Wuyan controlled the flying boat to travel more than ten miles, and then hovered over a blue sea, taking a deep breath slowly.

"Senior Chen, it's here."

Chen Qingyun and Liu Zhilan were warming up, and their eyes swept the sea below.

Along the way, they didn't see any spiritual islands. When they arrived here, they saw the same vast blue sea scene, and there was no reference point.

It is not easy to find a vein in this endless sea, remember the specific location, and avoid natural disasters.

"This sea heart crystal mine is in this sea area, about 500 feet deep. At this depth, mortals can no longer move normally there."

"Around the mine, there is also a group of rock armor crabs. The strength of these monsters is usually around the second level, and the highest is the second level of the best."

"It is precisely because we are afraid of these rock armor crabs that we know we are weak and dare not rashly enter the sea to mine. We can only watch helplessly all these years."

Shui Wuyan began to describe and sighed slightly.

"According to the observation three years ago, these rock armor crabs are continuing to grow, and the number is close to 400."

"Among them, the second level rock armor crabs are the majority, accounting for more than 340 heads, and the rest are all first level."

With this number of rock armor crabs, according to the strength of the monks on Huangsha Island, although they can fight and have a few chances of winning.

The three purple mansion monks of the three families are not vegetarians. They are more or less confident in fighting more than 300 second level monsters.

But this is the boundary sea after all. It takes manpower and effort to send people from the island to conquer this vein. In the battle in the sea, casualties are inevitable.

If things go wrong, there will be casualties during the voyage, and several foundation-building monks will be lost here, which will greatly damage their own vitality.

This result will take decades to recover.

In addition, the sea heart crystal vein is located on the seabed more than a thousand meters below. The three families do not have the ability to build a water-proof formation, and they will need to send monks to dive into the seabed for mining in the later stage.

The monks are short of manpower and have to take the risk of sailing back and forth in the boundary sea, taking huge risks.

The sea heart crystal mined in the end is like topaz, which cannot be exported and can only be digested internally.

So what is the ultimate meaning of all this tossing?

Combining the above, after weighing the interests many times, the three families can only put this sea heart crystal vein on hold.

Only when they are in a whim, they try to mine it once or twice, try their luck, and see if these rock crabs will migrate out.

However, the fact is that the rock crabs have settled here for a long time, and have been multiplying and growing. There are more than a dozen of them at the peak of the foundation building level.

The three families are not willing to confront this kind of monster power.

After listening to Shui Wuyan's emotional narration, Chen Qingyun opened his spiritual sense and swept into the sea.

The spiritual sense quickly penetrated more than 1,500 meters into the sea and had already touched the seabed.

The outlines of the clearly undulating mountains appeared, showing an east-west direction, stretching for more than a thousand miles.

This is a large group of submarine mountains. From the location point of view, it is not a deep sea area.

In the submarine mountains, many light groups appeared in the sea, sometimes in groups, sometimes scattered.

Those are luminous fish in the sea, with different shapes. The strongest ones are at the second level, hunting low-level spiritual fish and feeding on algae in the sea.

Seeing the signs of many creatures appearing on the seabed, Chen Qingyun noticed that these mountains have bred spiritual energy, and sometimes some bubbles will emerge from the seabed.

In some of the seabed sand, there are also signs of spiritual energy, and even pieces of spiritual sand.

Spiritual sand is the prototype of a seabed spiritual vein, born from heaven and earth, and presents an irregular shape.

Over time, these spiritual sands accumulate and gradually form spiritual veins under the continuous movement of the seabed plates.

Most of the spiritual veins in the sea are evolved from these spiritual sands.

"If there is spiritual sand, there are conditions for the birth of spiritual veins. No wonder it can breed fourth-level sea heart crystals."

Chen Qingyun continued to release his spiritual sense and carefully explored these mountains. He soon found the rock-shell crab that Shui Wuyan mentioned.

Rock-shell crabs are second-level monsters, about the size of elephants, covered with crab shells, and look like they are wrapped in circles of rocks, hence the name.

Their most obvious feature is a pair of red crab claws about one meter in size.

The toughness and sharpness of this pair of claws can easily crush stones in the sea and hunt prey hiding in the rock interlayer.

As a carnivorous creature, when the rock-shell crab population reaches a certain scale, it will also hunt third-level monsters in groups, relying on the advantage of ants biting elephants to death.

Huff, huff, a black sea snake that is more than ten meters long and as thick as a bucket is hunting in the sand on the seabed, chasing a colorful spirit fish.

The next moment, accompanied by a fishy smell, it was suddenly ambushed and attacked by a rock-shell crab and firmly caught in its claws.

Before the sea snake could struggle, two more rock crabs appeared nearby, waving their large claws and surrounding it.

The three rock crabs worked together to hunt, tearing the sea snake into several pieces in no time, and then ate it on the spot like hungry wolves, eating up all the prey.
