Ding! The System has announced the materials required to upgrade the sign-in level from three to four: 30kg of sea salt of any grade, 10kg of clay of Grade D Rare or above, two freshwater fish of Grade C Excellent or above, three bows of Grade D Rare or above, and one mountain axe of Grade C Excellent or above.
As the highest level of sign-in among all the Survivors was only level three, the system would not release the list of subsequent upgrade missions for the time being. After a Survivor broke through, the system would release it. The ranking system will be released in 72 hours.
The last two messages from the system were too important to Gu Beichuan.
"We are the highest level!”Yang Mi was even more excited than Gu Beichuan.
Gu Beichuan nodded, but he held his chin in his hand and started to think.
Among the materials needed to upgrade from Level 3 to Level 4, he could satisfy the last three. There was no problem with a C-grade fish. He could make a D-grade rare bow and arrow with the materials he had. He already had a C-grade Excellent Mountain Breaker Axe.
As for sea salt of any grade, he had a soup pot. As long as he took seawater and boiled it dry, the rest would be sea salt. The system did not have any quality requirements, so it should not be difficult to obtain 10 kilograms of sea salt.
The only thing that gave Gu Beichuan a headache was…clay.
Where could he find this thing?
Gu Beichuan opened the clay data.
Clay: mineral clay or marine clay. The mineral clay can be obtained from the kaolin mine, and the marine clay can be obtained from the shallow sea near the coastline.
What was a kaolin mine? Where could he find one…
It seemed that he could only go into the sea and try to dig some soil.
After Gu Beichuan finished thinking about his upgrade plan, he turned his attention to Yang Mi.
"What's wrong? Why are you looking at me?"
Yang Mi was confused.
"Aren't you going to level up?"
"Me?"
Yang Mi finally reacted.
Even if he had been recruited, he could still upgrade the check-in system.
" Any grade of palm tree trunk 50 kg, D-grade rare sand 10 kg, D-grade rare palm leaves 100 pieces…"
Yang Mi mumbled the list of materials she needed to upgrade.
"Don't worry, we have this."
Gu Beichuan raised his precious mountain axe high up.
For other Survivors, palm leaves were easy to obtain, but it was not easy to cut down 50 kilograms of palm tree trunks and collect 10 kilograms of sand.
First, most people didn't have decent tools.
Secondly, most people did not have transportation.
The system had specially noted that the collected resources had to be gathered together. Once the location was set, it could not be changed within three days.
50 kilograms of tree trunks and 10 kilograms of sand required manpower to move.
However, these thorny matters were not a problem for Ye Chen.
He had an axe, a bucket, and a pickup truck that could transport a few tons of goods.
At this moment, the system had released the mission material list for upgrading the check-in system.
All the materials related to the mission immediately increased in price.
Fresh water, daggers, kitchen knives, and other synthetic tools. plastic buckets, ceramic jars, and other containers that could hold sand; Even the price of the rope used to tie the palm leaves had risen rapidly.
Gu Beichuan had the " food " in his hands now, so he was not flustered at all.
Fresh water, axes, buckets, ropes, he had prepared them long ago.
He could even grow the vegetables needed to upgrade to level 3 in a few days.
"After fishing, hang it up in the trading hall and we'll drive out for a walk.”
Gu Beichuan calmly started fishing.
"Aren't you going to upgrade your check-in level first?”Yang Mi looked at Gu Beichuan leisurely fishing, as if he was not in a hurry to upgrade his check-in level.
"I can't rush it. I probably have to go to the beach to take a look.”
" Go to the beach? Because of…clay?"
"Yes, it's too difficult to find a mine on land. It's better to try your luck at the beach.”
As Gu Beichuan spoke, another C-class excellent fish took the bait.
Gu Beichuan had almost contracted the fish trade in the trading center.
From today onwards, there were already players selling freshwater fish.
However, the level of the other fish was far lower than his. It was obvious that it was because of the problem with the fishing rod. His fishing rod was a perfect B-grade fishing rod.
After using up the number of times he had fished for the day, Gu Beichuan left two fish that weighed one catty for dinner and hung up the rest of the fish he had caught on the exchange.
"Get in the car. We can go out and explore the road. Maybe we can find something good.”
Gu Beichuan put away the fishing rod, brought the mountain axe, bucket, rope, and other supplies, and called Little White.
Two people and a dog drove the pickup truck and left their base in the direction of the lake.
"Where are we going?" Yang Mi was still a little confused.
"Let's look for palm trees and sand. Maybe there's some on the beach.”
Gu Beichuan stepped on the accelerator, and the pickup truck suddenly accelerated. It passed through the jungle and headed straight for the beach.
These palm trees were probably the most common on tropical islands.
When they reached the beach, Gu Beichuan saw a large number of palm trees.
There was sand and palm trees.
All that was left was some stamina.
Gu Beichuan raised his mountain axe and hit a palm tree twice.
With a clang.
A palm tree that was about ten meters tall fell to the ground.
In order to make it easier to move, Gu Beichuan split the trunk into seven or eight sections. With a 50-kilogram trunk, one tree was enough.
Unexpectedly…
The palm leaves and sand that he thought were the simplest met with trouble.
Gu Beichuan plucked a few palm leaves and the system notified him," E-grade normal palm leaf.
This was awkward.
It turned out that this palm leaf was really particular.
Gu Beichuan squatted down again and carefully examined the trunk of the palm tree.
The system displayed,"
[Palm Tree Trunk: E-grade Normal Palm Tree]
" Well, it seems that we still have to find another tree…" Gu Beichuan scratched the back of his head in shame.
Gu Beichuan, who had suffered a loss, had to check carefully before cutting down the tree.
After checking three or four trees, he finally found a palm tree marked as D-class and excellent-grade by the system.
Gu Beichuan looked up. Good heavens, it was really a grade higher. Its head was much bigger.
"Clang, clang, clang."
Gu Beichuan spent a lot of effort to cut down the tree trunk.
"Drink some water. What about that tree?”Yang Mi obediently handed him a bottle of water.
Gu Beichuan gulped down a few mouthfuls and glanced at the two tree trunks that he had cut down.
"Hang it in the trading hall!"
"Trading hall? Someone wants this?"
"Of course, there are people who want it. Not only do people want it, but they will probably snatch it!”
Gu Beichuan was full of confidence.
"Snatch?" Yang Mi's face was filled with the word "disbelief".
Gu Beichuan did not intend to explain. He directly hung the trunk of the D-grade Excellent palm tree that had not been cut into sections in the trading hall.
