Hearing the double prompt, Xiao Yi decided to come out and harvest all the fish first.

Xiao Yi found that as long as Lu Ping'er threw the fish into the fishing net he was pulling, it was also his harvest.

With the assistance of Lu Ping'er and Anyue, it took more than an hour to collect all the sea fish.

"Materials obtained: marine fish*10234kg, marine fish (C-grade)*238kg, marine fish (B-grade)*56kg."

"Trigger double harvest, get materials: sea fish * 20468kg, sea fish (C-grade) * 476kg, sea fish (B-grade) * 112kg."

Looking at the sudden increase in sea fish, Lu Ping'er had no idea what was going on.

But Anyue looked as he should.

After harvesting the sea fish, Xiao Yi ran directly to Yuan Nong's side, harvested all the crops to be harvested, and then walked back to his bedroom.

Bathing and changing clothes, the last day of the fourth week, what kind of rewards will be given for signing in? Xiao Yi was full of expectations.

"System, sign in!"

"Sign-in is successful, the host has successfully signed in for a month, and a monthly gift package will be rewarded!" The system replied.

"Huh? Isn't there thirty days in a month?" Xiao Yi asked suspiciously.

"The system defaults to four weeks as January! It is inconsistent with the host's previous months!" the system replied.

"OK, open the monthly gift package!" Xiao Yi said immediately.

"Get supplies: Villa Card*1, Manor Card (S Grade)*1, Port Card*1, Wall Expansion Card (SSS Grade)*1."

"Trigger double harvest and get supplies: Villa Card*2, Manor Card (S-level)*2, Port Card*2, Wall Expansion Card (SSS-level)*2."

Looking at the few four supplies, Xiao Yi felt that this monthly reward was not very good!

"Villa Card: Immediately after use, a top-level luxury four-storey villa will be built, with three floors above ground and one basement floor!"

"Manor Card (S-level): Immediately after use, a 10-mu manor will be built, including one mu of housing and logistics warehouses, one mu of poultry breeding land, one mu of livestock breeding land, and the remaining seven mu of farmland, one mu of S-level, Two acres of A-level, four acres of B-level, there is a constant temperature system in the manor, which requires electricity."

"Port Card: Immediately after use, a small port will be built for parking ships. Ship maintenance can be carried out, and it has a certain defensive power!"

"Wall expansion card (SSS level): Existing walls can be expanded to a suitable size!"

After reading the explanation of the four materials, Xiao Yi finally understood how powerful these four materials are.

But after a rough calculation, his island can't hold so many things.

Just two manors cover an area of ​​20 acres, a total of more than 13,000 square meters, plus two villas, and the previous buildings, it has exceeded 20,000 square meters.

If you cut down more than half of the existing woods, that should work, but it's not worth the loss!

"No, we must start collecting the cornerstones with all our strength!" Xiao Yi didn't want to cut down all the forests that had finally evolved to this point!

After thinking about it, Xiao Yi called An Ran in.

"What's wrong?" An Ran asked.

"According to the statistics, we must collect a large number of cornerstones today for all the high-grade foods we have now!" Xiao Yi said.

Naturally, An Ran knew that the double state was unattainable, so she immediately greeted Su Wan and counted them together.

After a while, the statistics were handed over to Xiao Yi.

SS grade pure water 4500ml, S grade pure water 500ml, accumulated before the upgrade of the water purifier.

Grade A chicken 150kg, Grade B tiger meat 36kg, Grade B bear meat 57kg, Grade B marine fish 56kg, Grade C marine fish and freshwater fish 508kg.

S-grade corn 20kg, S-grade sweet potato 912kg, A-grade wheat 96kg, A-grade soybean 25kg.

S-grade milk 1300ml, A-grade milk 2500ml, A-grade eggs*300kg.

After Xiao Yi looked at the quantity of these supplies, he switched to the public channel of the island tablet.

"Everyone, I'm Yi Ranpin. In order to meet the unknown enemy next week, after discussing with the team, I decided to sell a large number of high-grade food. The items in this transaction are limited to cornerstones!" Xiao Yi said.

When everyone saw Xiao Yi's message, they immediately went crazy!

"Come again, come again, Big Brother Yi Ranpin is here again with graded food!"

"This time, the big guys said that it was a large number, which means that there must be a lot of them. I hope to grab some!"

"Then you have to prepare enough cornerstones!"

At this time, the internal forces of Emperor Lin also began to discuss.

"President, this Yi Ranpin is going to sell high-grade food again. It is said that there are still a large number of them!"

"Yeah, what do we do?"

Emperor Lintian replied: "Everyone, prepare the cornerstone, and try to snap up some high-grade food later."

"Yes!" the crowd responded.

Seeing everyone's response, Xiao Yi sent another message, saying: "Friendly reminder, today the sea water will erode the cornerstone of the island, so be sure to keep spare cornerstones!"

"We all know about the boss, hurry up and put the food on it!"

"Yeah, boss, everyone needs to consider this matter, you don't have to worry too much!"

"Always ready to snap up!"

Xiao Yi said again: "The highest level of food released this time will be S-level, and of course the price will be very expensive. Let's take a look at the cornerstones in your hands and determine your goals!"

"What? The highest S-rank? Where did the boss get it!"

"Lying Cao, it makes my blood boil! Hurry up!"

"I must grab an S-class food, even if I go bankrupt!"

When Emperor Lintian saw Xiao Yi's message, the whole person was shocked: "S-level food? How is it possible! How did he get it?"

Xiao Yi didn't have time to ignore everyone's shock, but switched to the trading floor and started listing!

The first is C-grade fish meat. Last time it was doubled, a cornerstone could be exchanged for 50g of C-grade fish meat. This time Xiao Yi increased it to 60g.

"[Fish] (Class C)*60g Trading [Keystone]*1."

Put all the C-grade fish on the shelves, a total of 8466 groups.

After it was put on the shelves, Xiao changed hands before he left, and was instantly wiped out!

"The transaction was successful, and the supplies were obtained: cornerstone *8466."

"Trigger double recovery, get supplies: cornerstone*16932."

Xiao Yi looked at the nearly 17,000 cornerstones, and the whole person became excited.

"Come again!" Xiao Yi said.

Next is the B-grade sea fish. The price is based on the C-grade fish meat, which is halved!

"[Fish] (Grade B)*30g trading [Keystone]*1." A total of 1866 groups.

In an instant, it was swept away again!

"The transaction is successful, ..., double harvest is triggered, and materials are obtained: cornerstone * 3732."

"Continue!" Xiao Yi rubbed his hands together and said.

Next up is the B-grade tiger and bear meat! When I doubled last time, a cornerstone was changed to 20g, this time Xiao Yi increased it to 25g.

After all, tiger meat and bear meat are more rare than fish meat!

"[Tiger (Bear) Meat] (Grade B)*25g Trading [Keystone]*1." A total of 3720 groups.

In an instant, it was swept away again!

"The transaction is successful, ..., double harvest is triggered, and materials are obtained: cornerstone * 7440."

After the transaction was completed, Xiao Yi switched to the public channel to watch it.

"Yi Ranpin is too powerful! This time, he has sold so many high-grade foods!"

"Yeah! And it's a little cheaper than last time. Last time, I only exchanged 20g of B-grade bear meat for a cornerstone, but this time I can exchange it for 25g!"

"What a conscientious businessman! I just heard from you guys that Yi Ranpin is good, but I didn't know what was good, and now I finally know!"

"Some people can't tell what's good, but it's not good, but Yi Ranpin is good, we can tell!"

Xiao Yi smiled and sent a message on the public channel: "Are you ready for the bombing of A-level food?"

"Wo Cao, here it is, it's finally here, the A-grade food is here, I'm so excited that I almost pee!"

"Then go to the toilet quickly!"

"Go away, I don't know what you're thinking yet. Let me go to the toilet. You should take the opportunity to grab two more groups! Think beautifully! I'd rather not pee my pants!"

"I suspect that you have kidney deficiency, Liuwei Dihuang Wan understands!"

"Go away, the counterfeit medicine seller is here again!"

Xiao Yi looked at his A-grade food. Now the question is, how should A-grade food be priced?
