Building Upgrade Cards. Final collection.

After Xiao Yi reprimanded Wang Cai, he walked over to the island monument, looked at the two medium sized sailing ships in the manufacturing space and said, "Let me see your style!"

Choosing the small wooden ship next to it, the two medium sized sailing ships were placed side by side!

After placing them, Xiao Yi walked out of the wooden house and looked at the sailboats next to the small wooden boat in surprise.

"So big!"

According to Xiao Yi's estimation, the medium sized sailboat was estimated to be ten times the size of the small sailboat, probably more!

Climbing onto the medium sized sailboat from the hanging ladder on the side, it was the first time Xiao Yi had boarded such an ancient sailboat.

In the previous world, Xiao Yi had traveled on large ships, but those were large ships made of steel, but this one in front of him was made entirely of wood, and it felt completely different.

Xiao Yi tried to drive the medium sized sailboat out, and he didn't expect it to be able to drive out, and it wasn't difficult to operate.

But he knew that this must be a correction of the power of the rules of this world, everyone can drive a boat out to sea, but when they really encounter an unexpected situation, the people who really know how to drive a boat are still very advantageous!

After turning around and then returning to the shore, Xiao Yi got down from the boat and prepared his own breakfast.

At this time, Wang Cai had already gripped all the 10 fish that he caught yesterday.

"Ugh, when can I eat some veggies!" Xiao Yi sighed as he looked at those crops he had planted.

Currently, he could only hope that the lettuce would mature soon, as only lettuce had the shortest growth cycle.

But even if the lettuce matured, with no oil and no salt, at that time, it was estimated that it would still have to be wrapped in grilled fish and eaten raw.

"There are still a lot of things missing!" Xiao Yi lamented, then said while flipping the grilled fish, "System, check-in."

" Check-in successful, obtained a Building Upgrade Card!"

"Building Upgrade Card: can upgrade any building to the next level, with randomness!"

"Randomness?" Xiao Yi was a bit puzzled.

"To give you a chestnut, you upgrade your ship, the next class has various functional ships such as frigates, destroyers, etc., if you use the upgrade card it will be upgraded to become any of them without being able to think of maneuvering it, that's randomness."

"This thing is good!" Xiao Yi's eyes lit up as he looked at his buildings, the most important thing that needed to be upgraded at the moment was his cramped wooden house!

The warehouse didn't need to be that big, and his own food wasn't so much that he couldn't eat it all yet.

There was still a lot of room to spare in the flower beds, the one with S-rank soil currently only had two coconut saplings, and the other one only had ten wheat seedlings and an apple tree!

The chicken coop already has two A-ranked ones and doesn't need to be upgraded at the moment.

Medium-sized sailboats are also enough for their own use in the early stages, and it's still a toss-up as to whether or not they'll be able to use them, there's no map, no goal, and there's not much point in taking a boat out!

Of course, whether or not a boat counts as a building is another story.

"It's the wooden house, after squeezing for so long, I can finally live in a bigger house!" Xiao Yi finally decided, "Use the upgrade card on the wooden house!"

"Please go to the island monument to operate!" The system prompted.

Xiao Yi froze and muttered, "It's still a powerful system, it's still compatible with the Island Monument!"

Muttering so, Xiao Yi came to the Island Monument, and then on the page of manufacturing, he selected his wooden house to be upgraded.

"Congratulations on upgrading your wooden house into a single apartment!" This was the system beep.

"Warning: the current island area is not enough to release the single apartment, please expand the area of your island as soon as possible, if the island area fails to meet the release requirements within 24 hours, this upgrade will fail!"

"What!" Xiao Yi shouted with wide eyes, his island currently has 63 square meters, but it's still not enough to release that bachelor pad?

After carefully checking the upgraded single apartment, it has an area of 36 square meters, which is the size of 6*6.

Currently, Xiao Yi also has two chicken coops, both of which are 2*2 in size, the warehouse is also 2*2 in size, the two flower beds are 1*4 in size, and there are also two large wooden pots both of which are 1*2 in size.

After a rough estimation, the area is still barely enough, but Xiao Yi set the fully automated fishing net to circulate around the edge of the island so that it occupies the outermost circle.

This, coupled with the fact that the boxes of supplies caught yesterday took up some of the locations, ultimately resulted in an insufficient area!

"As long as I completely stop the fully automatic fishing net and take care of those material boxes, I can still place all the buildings!" Xiao Yi muttered.

Of course this was something that Xiao Yi was only thinking about, although he had a check-in system, if he wanted to survive, he still had to rely on catching supplies and sea fish.

"There's no way, it looks like we can't wait for the double bonus, let's wait until the island is bigger in the future, then we'll build up the supplies box!" Xiao Yi shook his head and went out to finish off the grilled fish, then started to open the eight supply chests he fished yesterday.

All of them were opened.

"Obtained supplies: cornerstone*4, plastic*4, stone*2, bread*200g."

"Obtained supplies: cornerstone*1, wood*4, metal sheet*3."

"Acquired supplies: ..."

After the eight supply chests were opened, a total of 11 cornerstones were obtained, which were immediately used to expand the size of their island.

There were also two bottles of mineral water and some other basic supplies.

Xiao Yi pondered for a moment and immediately hung the mineral water in the trading hall of the island monument.

"[Mineral Water]*20ml trade [Cornerstone]*1."

At once, 50 groups were hung up, exactly two bottles of water!

"There are still the last two or three days, it's better to collect more cornerstones!" Xiao Yi muttered.

Today was already the fifth day, in two more days, the seawater would devour a square meter of cornerstones, and by that time, it was estimated that there would be no one selling cornerstones!

And the people selling cornerstones could definitely even regret their intestines!

If there were more cornerstones in their hands, they might even be able to sell them at a sky-high price!

However, Xiao Yi definitely won't sell the cornerstones, if he wants to exchange them, he has a lot of other materials that can be exchanged, there's no need to use the cornerstones, it's still more reliable to expand his own island!

Thinking of this, he cut the fish in the refrigerated warehouse and then hung it in the trading hall as well!

"[Sea Fish]*50g trade [Cornerstone]*1."

Leaving only the sea fish that was just harvested today for himself, all the rest were hung up, totaling 240 groups.

Because there was so much water and food hanging out, it instantly caused another hot debate.

"Those who have cornerstones in their hands hurry to the trading hall, there's something good!"

"I saw it, someone traded water and food for cornerstones!"

"There are still so many groups hanging around, this is the brother ah, when will I be able to have extra water and food like the big brother!"

"This cornerstone doesn't seem to have much use other than expanding the area, how much space do you need to be by yourself, it's better to trade for food!"

"That's right, I'm going to exchange it too, I have two cornerstones in my hand!"

"However, I suggest we keep a few cornerstones, it always feels like this thing has a great use!"

"You old man is very bad, I don't believe you, everyone hurry up and change it, don't look at the number of groups, it might be gone in the next moment!"

"Right, I agree with the words upstairs, everyone hurry to change!"

Xiao Yi looked at those people's discussion, shook his head and secretly said, "Change it, change it, in two days there will be you guys crying!"

"Ding, Su Wan requests to speak with you!"
