The dark red color is the color of gold after it is corroded and oxidized by sea water.
As we all know, gold is a very stable metal.
If gold is put into seawater, its content and purity will not change.
The gold content of gold can only be changed by smelting and purifying it, or by adding a small amount of other metals.
Due to the complex composition of seawater, gold cannot be absolutely pure gold and contains trace amounts of other metals.
Although gold will not react in a short period of time, being soaked in seawater for many years will cause the surface of gold to be oxidized and turn dark red.
From this, Huo Yu deduced that the dark red metal weapon in his hand was clearly a sword made of gold!
If it were just a golden sword, it wouldn't be worth Huo Yu's surprise. After all, the purity of gold was not high in those days, and a golden sword could only be that much.
What really surprised him, and even made him shudder, was a mark above the handle of the sword.
It was a sign that was also dark red and looked like an inverted flame.
Since it is similar in color to the surface of oxidized gold, only an outline can be barely seen.
But it was this outline that made Huo Yu decide that it looked familiar. He had seen this logo not long ago.
On the bottom of the drone sent by the illegal organization to spy on the 249 scientific research station, there is also an identical dark red logo, like a small flame!
Huo Yu was shocked.
A golden sword found in the remains of a ship sunk for thousands of years.
The other is a drone sent by an illegal organization carrying out illegal activities in the Arctic region.
They actually use the same logo!
Is it just a coincidence?
Or are they inextricably linked?
Huo Yu looked at the direction of the little black ball.
Seeing that the audience was interested in these treasures, Huo Yu simply controlled the little black ball to take pictures of the cultural relics and treasures.
Now that he was out of the range of the camera, Huo Yu took a look and directly put the golden sword in his hand into his space backpack.
This sword should not be a spiritual weapon or a supernatural weapon. It is just an ordinary golden sword, otherwise it would not be corroded into dark red by the sea water.
However, the logo on its hilt involves too much and is not suitable for exposure to the public.
Huo Yu decided to take it back first and then make plans.
After finishing everything, Huo Yu looked down at the dashboard and found that there was not much compressed air left.
He decided to go out first, return to the ship to change the air tank, and then explore other areas of the sunken ship.
He had a hunch that there was a huge secret hidden in the wreckage.
Controlling the little black ball to leave, the audience immediately started shouting.
"Don't leave, Mr. Yu, there are so many cultural relics, just take any one and give it away."
"You're overthinking it. You can't sell these cultural relics once you take them. You can only keep them for yourself."
"Anchor, I am Qin Shihuang. I am not dead. These cultural relics are gifts for the immortals when I sent Xu Fu to go to sea. Please bring them back to me immediately. I can make you the general who protects the country!"
"Stop talking, you've been down for such a long time, Master Yu must have run out of oxygen, right?"
Huo Yu gave a thumbs up to the camera and pointed to the oxygen bottle behind him.
Seeing that Huo Yu returned because there was no oxygen, the audience stopped complaining and began to discuss the cultural relics one by one in the live broadcast room.
Huo Yu hid behind his diving helmet and rolled his eyes.
What's the use of discussing this? It's not yours.
These cultural relics must be handed over to the state.
What? Not a Chinese ship?
It contains cultural relics from our country, so why is it not a ship from China?
...
Returning along the original route, the sea water became a little turbid because a large number of boxes were damaged by hordes, causing wood residue, clay, rust and other impurities to be mixed into the water.
For this reason, Huoyu spent more time coming out of the sunken ship. When he saw the little beluga waiting anxiously outside again, the air content was almost bottoming out.
When the little white whale saw Huo Yu, he immediately came up to him excitedly, like a child in a kindergarten waiting for his parents to take him home.
Huo Yu didn't have time to interact with the little guy and pointed to the water.
The little white whale understood what Huo Yu meant, took the initiative to run under Huo Yu, and humped him again.
After tying themselves together with the little white whale again, one person and one whale swam toward the surface.
Huo Yu looked at the dashboard and saw that the air content index bar had turned red.
This means that within three minutes, the oxygen in the compressed air tank will be exhausted.
Fortunately, the little white whale was very fast and rushed directly to the water. In just over two minutes, one person and one whale returned to the water.
Seeing the sun above his head again, Huo Yu took off his helmet and took a deep breath of air.
Although you can breathe compressed air underwater, you need to control your breathing rhythm, which is far less enjoyable than breathing in big mouths like now.
The little white whale floated silently on the water, also breathing.
Because the beluga whale needs to open the blowholes on its back to ventilate, the hawk fish moved back slightly.
Although it's a bit rude, Huo Yu doesn't want the little white whale to breathe on his butt...
Such a long-term deep dive is not easy for the little white whale.
For whales, deep diving and ordinary swimming are two different concepts.
Whales need to breathe more frequently when diving shallowly, and they have to breathe every 12-20 seconds on average.
When a whale dives deeply, its lungs will be under greater pressure, and the alveoli will be shrunk and compressed, forcing the remaining gas into the larger trachea in the body.
When the exchange surfaces of the alveoli are completely compressed to a minimum, the whale's lungs can perform little or no gas exchange for long periods of time.
The whale's body structure is very strange, and it is beneficial and harmless to it not to breathe when diving deeply.
Not breathing not only reduces the risk of nitrogen diffusing into the blood, but also reduces the risk of small bubbles forming in the blood as it rises to the seafloor, so whales' lungs rarely exchange gases when they dive.
After the little white whale finished breathing, Huo Yu started to look around.
The water outlet is not far away from the "Red Dragon Boat". From here, the "Red Dragon Boat" is already as small as a toy boat.
After resting, Huo Yu and Little White Whale rushed towards the direction of [Red Jiao].
Next, Huo Yu plans to explore the sunken ship.
Logically speaking, the Icekeepers organization would not be responsible for such work as salvaging ancient sunken ships.
And there are very few precedents of ancient shipwrecks being discovered in the North and South Poles.
This kind of work is more focused on historical archeology and cultural relic protection. As an environmental organization, the Icekeepers will at most release shipwreck information to the public.
Internationally, there are companies specifically responsible for salvaging sunken ships.
But this sunken ship is somewhat special, and there are too many doubts about it.
The mere presence of ships from hundreds of years ago in the Arctic Ocean is suspicious enough.
Not to mention the logo that is the same as that of an illegal organization.
If the speculation is true, then what is the purpose of an illegal organization that has been hidden for more than two hundred years?
