Seeing Jiang Chen, he instantly understood.
Xiao Yin happily nodded and clapped her hands.
"Wait for me."
Jiang Chen said.
Then, he walked to the side of the raft and jumped into the sea.
He dived into the sea.
Jiang Chen followed Little Yin's lead and swam to a certain place.
After circling around the deep water area for a while.
Xiao Yin stopped at a spot and pointed at a small hole at the side.
That small hole was dug open by it.
Jiang Chen looked around.
This was a spot near the stone wall of the island.
Moreover, because it was in the water all year round, the position of Little Sound's finger was covered with thick mud and rotten leaves.
Jiang Chen didn't see this place when he was observing.
Because the black mud and the deep waters were too dark.
He swam forward a little.
Jiang Chen used his hands to slowly push away the layer of mud.
But halfway through.
Jiang Chen's palm touched a layer of objects.
He opened it up with his hand, and the entire layer of mud was opened up at once.
From the back, it looked like a waterproof fabric.
However, when Jiang Chen looked inside, he saw a scene that contained a lot of information.
It turned out to be a cave.
The cloth that Jiang Chen had just uncovered must have been something like a tent that had collapsed outside the cave a long time ago.
Inside the cave.
There was an abandoned wooden bed and a blue and red waterproof plastic box.
It was unknown how many years the seawater had corroded, but the plastic box was still intact.
It was about the size of two basketballs, and there were two paw prints on it. These were from Little Yin.
But that was not the main thing.
It was because the information that the whole thing brought to Jiang Chen was more important.
What did this mean? This meant that someone had lived on this island for a period of time.
Moreover, it also explained a principle.
That was, not only was the shallow water part of the sea.
Now, it seemed that the deep water area was also a part of the sea.
However, who knew how much time had passed?
The original sea area had now become a deep water area.
It was really a sea of change, and the tenses were ever-changing.
However, he could forget about sighing.
Jiang Chen searched the cave carefully to see if there were any other clues.
Unfortunately, there was nothing else besides this box.
Alright then.
Jiang Chen carried the box, and then swam upstream quickly with Little Yin.
Crash ~~~
He swam out of the sea and dragged the box up.
Jiang Chen folded his arms and thought for a while. Then he looked at Little Yin, who was waiting for him to open the box.
"You drive and try your luck.”
Huh?
Xiao Yin was stunned and didn't even have time to react.
But since Master said so.
Xiao Yin walked forward to the chest and placed her claws on both sides.
Then, he opened the box with a bang.
At the same time, the notification that Jiang Chen had obtained an item sounded.
[Acquired: Blueprint: Perfect-grade wooden board]
！！？
Was it really useful?
Jiang Chen looked at Little Yin. He felt that it was almost the same now.
Xiao Yin was definitely a pet that could bring good luck!
It was absolutely not a problem to say that it was an auspicious beast that could bring good luck!
Even if it did not affect the system's check-in reward.
However, it was enough that it could affect the rewards obtained from the daily lottery.
She was happy to see Jiang Chen.
Xiao Yin didn't care about the reason. She raised her hands happily anyway.
Jiang Chen took out the manual and turned to the third page.
Then, he checked the requirements for the perfect-grade wood.
[Perfect-grade wooden board: Wood 20/20, Nail 0/2]
It was actually a wooden board that needed nails.
Moreover, a single plank required 20 units of wood.
It was ten times the floor of an ordinary raft!
[Perfect-grade wooden board: With it, a storm is like a drizzle to you. Only tsunamis and typhoons can challenge it.]
At the same time, it was also a necessary material for the construction of rafts and ship blueprints. If one wanted to build a ship, they needed at least good wooden planks, but the higher the level of wooden planks used, the stronger the ship.
As expected.
Although the materials needed to build it were many and expensive, the effect was obvious. These materials were very worth it.
After all, no matter how many materials one had, they would not be able to obtain them.
In the end, a shipwreck could make you start from scratch.
What was there to play with?
Therefore, it was all worth it.
Jiang Chen nodded. He closed the manual and returned to the system.
Now that he had the sail blueprint, he had the conditions to build it.
He had good wooden planks, but he was still short of materials.
However, if he did some calculations…
8 x 20 was equivalent to 160 raft floors.
160 raft flooring x 20 wood and 2 nails.
The final result was that he needed 3200 wood and 320 metal pieces!？
And his shark meat seemed to be able to exchange for a lot of wood.
Jiang Chen thought for a moment.
"Increase the price of shark meat?”
After thinking for a while, he decided to forget it.
The most important thing was that the price Jiang Chen had offered had reached the upper limit of their storage materials.
At this moment, even a Survivor with very good development should not have more than 200 materials.
Therefore, there was no need to raise the price anymore.
He had to look for it from other aspects.
For example, he still had a few apples that were about to rot.
