Whether it is a box containing gold and jewelry or a box containing silver, Ao Muyang has made special treatments, with eye-catching colors and chains to facilitate fixing on the tiger's saddle.

It is not easy to come to Beibu Gulf, and it is even more difficult to transport gold, silver and jewelry from Beibu Gulf, so Ao Muyang strives to search thoroughly. He is very particular about it and searches all the places where gold and silver may be hidden.

Some water caves contain copper coins from that time. These are genuine antique artifacts. Many are more expensive than gold, but they are completely damaged until they are soaked in the sea water.

There are also some treasures of official kiln porcelain from the time, which were also destroyed due to seawater corrosion and plankton parasites.

In fact, in addition to gold and silver, most of the other things such as porcelain, copper coins, jade, pearls, etc. have been destroyed and have little value.

After searching the water cave, Ao Muyang conservatively estimated that he had brought back two hundred kilograms of gold!

The proportion of gold is too large and the density is too large. As long as the size of a palm is one kilogram!

On the contrary, silver is not as large as expected. They are roughly more than seven or eight times more than gold. However, considering that the density of silver is only about half of gold, then counting that these silver does not weigh a ton of them.

Loading gold and silver, Ao Muyang and the tiger set out on their way home while the night was dark.

From Beibu Gulf to Brick Island, even if you drive continuously at the highest speed, it will take as many as a day and night.

Among them, sea fishing boats can drive continuously, but tigers cannot. They must rest. In this way, it is already August after returning to Brick Island.

Fortunately, the journey was calm and smooth. Ao Muyang met two waves of coast guards, but they both belonged to the Hongyang Coast Guard Detachment. Both sides knew him, but the other party did not doubt him.

These gold and silver boxes were hidden by him in the seaweed jungle of Brick Island. They were even safer to hide in this place than to hide under the ancient temple. No one could find boxes hidden in the clumps of algae on the bottom of the sea.

Seeing Ao Muyang coming, the old man Ao Zhibing quickly said, "Boss, I am planning to tell you, we have encountered some problems in our fishing ground."

"What's wrong?"

The old man said helplessly: "That's right, a big tuna in the fishing ground spawned a while ago..."

When Ao Muyang heard this, he was very surprised: "Did the tuna lay eggs? That's great!"

As far as he knows, humans know very little about bluefin tuna spawning because they have not been scientifically observed. Although Japan has completed artificial tuna breeding, it has not yet achieved artificial control of bluefin tuna breeding.

What people know now is that wild bluefin tuna spawns in different waters. For example, spawning in the Gulf of Mexico takes from April to June, and spawning in the Mediterranean takes from June to August.

According to fishery science speculation, the difference in spawning time of bluefin tuna in wild cases is caused by many factors, such as different environmental factors and genetic variations.

Bluefin tuna spawns in the fishing grounds, but Ao Muyang does not expect that their own fishing grounds will reproduce them manually, but only asks that big fish will produce small fish, thus forming an important link in the food chain.

A female bluefin tuna can produce as many as 10 million eggs per year on average. Their eggs have buoyancy and are distributed over a considerable distance through the surface current, which in turn hatch into small fish, which can be scattered almost throughout the fishing ground.

These tens of millions of eggs may not be able to hatch all, but even if one-fifth of them hatch, there are still two million small fish. The small fish prey on the plankton in the water and can become food for large fish, shrimps and crabs.

Seeing his face full of joy, the old man smiled bitterly: "What's so good? These fish have attracted devil eels!"

When Ao Muyang heard this, he frowned.

The devil eel is the name of lampreys by the Red Foreigners. Ao Muyang had come into contact with lampreys some time ago. At that time, the fish parasitized on the rats and porpoises and asked him to pick them one by one.

Old man Ao Zhiman said: "About three days ago, a bluefin tuna kept fluttering on the sea. I thought it had made something wrong, but later I found out that two devil eels were parasitized on its back."

"Has it been done?"

The old man shook his head helplessly: "How can I do this? Tuna always runs away, and I can't get close to it at all. Just Jin Huizi's girl looked good and saw clearly that there was a devil eel on her back. Later, I caught the big yellow croaker and looked at it, and found that there was a devil eel. Tell me, why did this thing suddenly appear so many?"

It is indeed rare for lampreys to appear suddenly. They are parasitic fish. Although they are motivated, they rarely take the initiative to make long-distance treks to change their habitats.

So, how long is the long distance for lampreys? It’s only ten kilometers!

Ao Muyang dared to guarantee that there must be no lampreys within ten kilometers of the surrounding area when he opened the fishing ground, because there were no big fish here at that time, and lampreys had to parasitize on the big fish to survive.

Mr. Ao Zhibing means that the tuna fish boy attracted lampreys. Indeed, in addition to parasitizing large fish, lampreys may also catch very small fish seedlings for food.

Lampreys have good vision and developed eyesight. They have a big mouth. When there are no big fish for parasitization, they will also chase the young fish to live.

Ao Muyang felt that this was not the case. He thought of the huge sperm whale, perhaps these lampreys brought by the sperm whale.

He had never found traces of lampreys on sperm whales, which was normal. Compared with the huge size of sperm whales, lampreys are too small, and there are many scars on sperm whales. Lampreys can completely hide in the creases of fish skins.

This is not an urgent task, it is urgent to help bluefin tuna deal with these parasites quickly.

He learned about the situation and then dived into the water.

The swimming route of the bluefin tuna was traced. He came and waited for a rabbit to wait near an oxygen generator. He soon saw the big tuna that was living in a double resident.

He released a little drop of gold and spread it in the water, and the two tunas were immediately attracted.

At this time, Ao Muyang approached them, trying to catch the gills of the fish and help them solve the parasitic lampreys on their backs.

As a result, the bluefin tuna was very afraid of people. I don’t know if it was because it ate too little gold drops or was so innate. They were not as intimate as tigers and dolphins. When he got closer, the two fish quickly fled.

Ao Muyang failed to succeed after several experiments, so he could only surface temporarily. Obviously, he could not pick the lamprey from the tuna with his own strength.

He was thinking about how to solve the arrival of lampreys in the fishing ground. In the evening, there was a phone call from the village: Ao Mupeng, who was sent to monitor the wharf of Wangjia Village, took the initiative to contact him.

When the phone was connected, Ao Mupeng said, "Longtou, the Tutulong next door of Mala has been opened, how can I do it?"
