In order to ensure his own safety, Bick did not immediately explore what were below the sea surface after he stopped the raft.
There was no land around here, so the ship should have sunk at the bottom of the sea. If he recklessly went down, he might really encounter unknown risks.
Moreover, if he was in the shallow sea, he could still see some light. If he did not prepare a lighting tool in the deep sea, he would be like a blind man.
If he could not see anything, it would be meaningless even if he touched the shipwreck. He had to create a lighting tool that could be used underwater.
Thinking of this, Bick opened the God's domain slate and searched for a lighting device that could be made.
Soon, he found a few options.
[Pumpkin lamp: Pumpkin (0/1), charcoal (0/1), metal plate (2/2)]
[Lantern: Charcoal (0/1), metal plate (3/3), glass plate (3/3), wood plate (1/1)]
[Inextinguishable lantern: Mana crystal (0/1), metal plate (3/3), glass plate (3/3), wood plate (1/1)]
Bick was a little depressed...
The pumpkin lamp and lantern obviously could not be used under the sea.The only option would be inextinguishable lantern that could be used under the sea. But it was the same problem, he did not have enough mana crystals!
Helplessly, Bick could only check the trade interface to see if there was any transaction.
[Trade]
[You have a successful transaction. You have obtained mana crystal x1!]
"Great! You came just in time!"
Seeing the notification, Bick was so excited that he almost laughed out loud.
He quickly opened the interface and began to create the inextinguishable lantern.
In less than ten seconds, a small lantern with a wooden handle appeared in Bick's hand. The core of the lantern was a mana crystal that emitted purple light, and the outside was a glass cover with a metal edge. The light was bright enough to see things that were five to six meters below the sea surface.
However, such a distance was enough.
As long as one touched the shipwreck at the bottom of the sea, not much light would be needed. It was just a supporting role.
Next, he had to make the final preparations for diving.
Bick opened the plastic jar and drank a few mouthfuls of water. He carried the wooden backpack on his back. He held the inextinguishable lantern in one hand and the spiked spear in the other.
"Einstein, guard our raft well. I'm going down to look for the treasure!"
"Ou ou! Ou ou ou ou!"
Einstein nodded, but there was clearly some worry in his voice.
Bick waved the spear in his hand and smiled, "Don't worry, wait for me to come back!"
After saying that, Bick plunged into the sea. With the water elemental affinity, Bick could move freely in the sea. Even though he was holding something in both hands, he did not feel uncomfortable at all.
As he continued diving, the light in the sea became dimmer and dimmer. At first, he could still see the raft above his head, but gradually, he could only see a light blue on the top of his head.
Then, the color changed to deep blue, a deeper blue, and it was even an endless darkness.
The only source of light was the purple light emitted by the inextinguishable lantern. However, wherever the light reached, he couldn't see anything except the sea. Bick could only rely on his senses to continue diving.
After a while, he finally saw a blurry black figure below. Under the purple light, the black figure gradually showed its original appearance.
It was a large ship that had been broken into two parts. The metal shell had lost its luster due to the corrosion of the seawater. Could it be that some undersea creatures could be seen swimming in the crevices of the ship.
Bick gradually approached. His feet landed on the broken deck, and he felt a faint sense of unease in his heart.
It seemed that from the moment he approached this area of the sea, something had been spying on him in the dark. The closer he got to the shipwreck, the more obvious this feeling became.
"What is it?"
"Could it be the souls of those who lost their lives in the shipwreck?"
"If that's the case, it'll be more troublesome..."
Bick could kill sharks and octopuses, but he had no experience dealing with spirits.
However, he seemed to have seen some magic weapons on the interface of the God's domain slate.
For example, the octopus soul magic staff that could not be made due to the lack of mana crystals. There were also some other weapons that had magical effects.
'It seems that it won't be easy to obtain the materials on the shipwreck...'
Bick thought in peace. However, he was unwilling to return empty-handed. Hence, he began to explore the interior of the shipwreck along the broken deck.
With the faint light of the lantern, Bick walked deep along the passage in the cabin. When he encountered a damaged cabin, Bick would go in to take a look at the things inside.
However, other than some corroded materials, he found almost nothing. After searching more than a dozen rooms, he only found some rusted metal fragments that could be picked up.
[Rusted metal fragments]
[Explanation: Materials that can be used to refine metals. They are equivalent to metal ores.]
Although rusted metal fragments weren't invaluable materials, they were extremely rare. Therefore, when Bick saw them, he would put them into his wooden backpack. In less than twenty minutes, he had filled a space in his backpack.
"Although this thing isn't very valuable, it can still refine metals!"
Bick laughed self-deprecatingly and continued to walk deeper into the cabin.
The cabin in front was obviously less damaged. Bick even saw a sealed metal box in one of the cabins.
"Hehe, there must be something rare in here!"
The surface of the metal box had been corroded by seawater, but the seal was still intact. Bick tried to open it with his hands, but found that the box was locked.
"Looks like I'll have to use the universal tool hammer!"
Bick did not stand on ceremony. He took out the universal tool hammer and smashed it down.
There was no other reason. He had to open this thing sooner or later. If he could not open it with his hands here, then he would not open it even if he went up. Thus, it was better to break it down now.
Bang!
As the lock was broken by Bick, the metal box bounced up, and Bick saw everything inside in an instant.
[You have opened the hidden treasure chest!]
[You have obtained rum x1!]
[You have obtained compressed biscuit x2!]
[You have obtained mana crystal x1!]
[You have obtained treasure map x1!]
"F*ck!"
"There are so many things!"
"Rum? Compressed biscuit? Mana crystal? This is too fantastic!"
Bick was excited. After all, he had never seen something like rum ever since he entered this game.
As for the compressed biscuits, they were a necessary survival item for the apocalypse. One compressed biscuit was equivalent to a day's worth of rations!
"There must be other hidden treasure chests here. I must search carefully!"
Bick put all these things into his backpack and looked at the treasure map in particular, but he did not have any leads.
He suddenly raised his head and came to another cabin.
At the door of this cabin, Bick saw two or three skeletons with only bones left...
