It seems to be completely different from what I imagined, the more I went down into the trench, the temperature of the sea water became a lot hotter, although it was a little unbelievable, but this was indeed a fact that Yang Dezhu and Yan Rong personally experienced.

There are many forks in the trench, but Yang Dezhu and Yan Rong will not explore separately. After all, they are not a professional scientific expedition team, and they do not have any investigation tasks. The most important thing is to keep each other safe.

Deeper into the trench, the variety of organisms began to multiply. A sea turtle the size of a millstone, a sea snake that is only the thickness of a finger, but is as black as gold and iron. These are all creatures that Yang Dezhu and they can recognize. There are also most strange creatures, Yang Dezhu and Yan Rong can't name them at all. They're only recognizable to any other creatures on land.

And unlike the desolation above the trench, marine vegetation has begun to grow in the warm waters beneath the trench. Although it is not green at all, but somewhat purple, the wide leaves and thick trunk all indicate that it is indeed a plant.

After carefully investigating two or three trench branches, Yang Dezhu probably found the cause of these strange phenomena. Because there is always a place in the deepest part of the trench where hot water gushes up, and it seems to be fresh water.

So Yang Dezhu guessed that this might be the end of a certain lower river, because it flowed through an undersea volcano, and heated the drinking water. This is the kind of existence that resembles an undersea hot spring.

Soaking in the warm waters gives you the comfort of being back in your mother's arms. It's no wonder that it's home to not only strange animals, but also plants. It's a small ecosystem.

Exploring such a trench is like exploring a strange and unknown planet, and it is full of motivation before you know it. Therefore, Yang Dezhu and Yan Rong were also full of interest and had no sense of fatigue.

After all the small branches were walked, Yang Dezhu asked Yan Rong in sign language how long he could hold on.

Yan Rong gestured and said that it was no problem, so the two decided to continue exploring a larger, diagonally extended branch.

This branch is much deeper than those small branches, and the temperature of the sea is also higher, and Yang Dezhu and his face seem to be swimming in a hot spring. Of course, the larger trench is also much more lively. Every few meters that Yang Dezhu and Yan Rong advanced would startle a lot of aboriginal residents. While they feast their eyes on all kinds of strange creatures, they must also be nervously defended. In a sea turtle tried to attack them. After being beaten away by Yang Dezhu's steel fork, another huge octopus tried to attack Yan Rong in vain.

Yan Rong is also the girl who has never seen the world from time to time at this time. She didn't scream nervously either. Instead, while resisting the tentacles with a steel fork, he took the time to shoot an arrow at the octopus's head with a crossbow. The octopus couldn't understand how the other party attacked it. But the creature instinct tells it that although the other party seems weak, it is not easy to mess with. So the octopus quickly ran away.

Just now, Yang Dezhu had been skimming Yan Rong beside him, and seeing that Yan Rong had dealt with it properly, he gave her a thumbs up as a compliment. Then swim over and pick up the bolts and reinstall them on the face.

The octopus's defense is still very high, and the crossbow bolts sting it but don't really hurt it.

After these two encounters, the creatures in the trench also seemed to know that these two strange guys were not easy to mess with, and Yang Dezhu and Yan Rong were a lot more courageous. Continue to the depths of the trench.

As he swam and entered the trench, a behemoth appeared in front of him blocking the way. Yang Dezhu and Yan Rong were both shocked, and vigilantly put their fingers on the switch of the gas pump, ready to negotiate at any time.

However, Yang Dezhu observed carefully for a while, and saw that the big thing didn't seem to move. Yang Dezhu couldn't help but be a little interested, this time it was supposed to be an expedition, how could he run without encountering real danger. So he moved forward a lot. However, he didn't let Yan Rong follow, and let Yan Rong stay where he was.

When Yang Dezhu stopped and got close enough, he suddenly breathed a sigh of relief, and gestured to the face behind him to let her come over.

When Yan Rong swam over and saw the true face of this behemoth, he couldn't help but be full of excitement.

It turned out that this huge object was not actually a living thing. It's a shipwreck.

In fact, as early as seven or eight hundred years ago, human beings began to explore the ocean. However, the sea is windy and the waves are high. Even a steel ship made with modern technology is not sure to be safe. In front of the might of heaven and earth. After all, human beings still seem small.

So. From ancient times to the present, there have been countless ships of all ages that have sunk on the sea. Although there are some ocean-going companies that specialize in the business of salvaging wrecks. But it is also impossible for them to search the entire sea. Besides, Yang Dezhu, the depth of the sea is already a forbidden area for them. At this depth, only the strength of the national level can be salvaged. But the state will not do such a thankless task. Unless it is determined that the wreck is of great significance.

Yang Dezhu's current location is out of the territorial waters of China, and it is an open sea. So salvage the wreck here. In accordance with international practice, it is fully owned by the individual.

Although the purpose of Yang Dezhu's trip was not to find the shipwreck, they could have an unexpected gain. Where would you refuse? Besides, isn't it a very exciting thing to explore the shipwreck?

In order to ensure safety, Yang Dezhu and the others did not act rashly. Instead, he went back to the submarine and directed the submarine to move here.

The larger branch of the trench allows the submarine to dive lower, so it can also be used closer to meet them.

Seeing that the blue light representing the position of the submarine was a few tens of meters away, if the gas propulsion was turned on, they would have arrived in two minutes. Yang Dezhu and Yan Rong suddenly felt a lot safer. With an excited face, he leaned over to the wreck.

And Liu Qianqian and Qingtian Mei Gardenia in the submarine adjusted the focus of the lens, and with the help of Yang Dezhu's lighting, they finally saw a sunken ship ahead. Immediately screamed excitedly inside the submarine.

Even ocean-going companies are not always ready to encounter shipwrecks. Finding a shipwreck in the sea is a real needle in a haystack. Which of those ocean-going companies did not consult a large amount of information, then determine a rough range, and then look at all kinds of advanced equipment to search and sometimes find the wreck by chance. And their chance encounter is simply like the probability of winning the lottery. I didn't expect this to be able to happen, how could this not make them scream with excitement.
