"Sign in successfully, get a reward: Master Key (SSS level)*1."

"Trigger double harvest, get supplies: Master Key (SSS level) *2."

"Master key (SSS level): A magical key that can open any mechanical lock and can be used unlimited times!"

"Great!" Xiao Yi said excitedly looking at the sign-in reward.

Yesterday, I could only look at the pirate treasure chest and sigh, but now I can open it immediately.

Xiao Yi took out a master key from the system space, walked to the pirate treasure chest in the corner of the room, and inserted it into the keyhole.

Clap!

The pirate chest is opened.

"Obtained supplies: cornerstone * 50, arrow rain launcher manufacturing map * 1, return stone * 1."

"Trigger double harvest, get supplies: cornerstone * 100, arrow rain launcher manufacturing map * 2, return stone * 2."

Xiao Yi has systematic prompts, you don't need to get to the island monument to know what these things are, even more detailed than the explanation on the island monument!

"Arrow Rain Launcher Manufacturing Diagram: It can launch a hundred arrows of various types at the same time. Materials required: wood*10, iron*3..."

"This is even more powerful than the arrow cart that was snatched from Park Yiye before!" Xiao Yi muttered while looking at the explanation.

Previously, the arrow cart could only fire 50 arrows at the same time, and they could only be daily wooden arrows or bamboo arrows.

And this arrow rain launcher can launch all kinds of arrows, and rockets can also be launched!

Two arrow rain launchers are launched at the same time, that is, two hundred rockets, which is equivalent to two hundred people attacking together, which is a big killer!

"City Return Stone: It can be used at the island monument, and the island monument is used as the coordinate point. After use, the individual can quickly return to the coordinate point. The casting time is 20 seconds and the cooling time is one day. Note that this city return stone can only be used by a single person. You can carry items no larger than your own volume or weight, and you can repeat the coordinate point change.”

The explanation Xuanyuan Wuwei saw in front of the island monument was only the first sentence, and Xiao Yi's system added two explanations.

"It turned out to be this thing!" Xiao Yi finally understood what Uncle Chen said about the treasure that went to Xuanyuan Wuwei Island safely!

The cooling time of this thing is much faster than that of the direction stone. Although one day is quite long, it is still less than seven days!

The direction stone can be teleported with everyone within the range, and the casting time can be as long as half an hour.

The return stone can only take one person, and the casting time only takes 20 seconds.

Both have their pros and cons.

With this return stone, Xiao Yi's plan to send spies to Autumn Wind City can move forward again!

Xiao Yi got up and walked out. How to use this thing, I will study it later, and now I need to get it quickly!

Going down to the first floor, Xiao Yi said: "Su Wan, you said in the group, that today our team will release some graded food again. The rules are the same as last time, and the specific exchange rate will be fine-tuned!"

"Yes!" Su Wan replied, and immediately posted a message in the Yi Tian group.

"Everyone, our island owner, Yi Ranpin, has decided that some graded foods will be put on the shelves today. The quantity on the shelves is the same as the previous rules. The specific exchange rate will be fine-tuned!"

"Wo Cao, are you here again! Fortunately, I have kept the cornerstone, and I hope I can exchange for more high-grade food!"

"Yeah, after eating high-grade food last time, I feel that I am rejuvenated again, this time I must grab more!"

"Me too, but C-level animals have been spawned in the woods on my island. I hope I can grab some high-end food!"

"Boss upstairs, can you sell me some C-grade meat?"

"Don't think too much, I can only encounter a hare occasionally, and it's very difficult to catch. C-level rabbits can't be caught at all! Last time I struggled for two days and set up a net to catch the C-level rabbit. The rabbit caught! It's only enough to eat, it's impossible to sell it to the outside world!"

"You're pretty good, I don't know when a C-rank wolf appeared in my woods, Mad, I almost died in its hands, and I was injured, and I returned to my house!"

"Why aren't so many animals spawned in my woods?"

"Oh, it's really refreshing, and you have a big head! I want to ask the injured man, how did you deal with your wound?"

"Now the injury should be hard resistance!"

"No, looking for and selling fake medicines, his medicines still work!"

"Then those who sell fake medicines are so powerful?"

"Don't sell fake medicines one by one, I'm an authentic doctor, okay?" The medicine seller said at this time.

"Sure enough, there are people selling fake medicines, can you also sell me some medicines for bruises and injuries!"

The medicine seller replied, "Today, I'm riding the big boss's east wind and selling with the boss!"

"Seller of counterfeit medicines, why do I hear your words so twisted? Are you sure you want to sell them together with the boss?"

"How many cornerstones, you and the boss, I'll take care of the old lady!"

"Damn, you old drivers!"

The medicine seller sent a message to Xiao Yi and said, "Big brother, I will sell the herbs in my hand with you today, is it alright?"

Xiao Yi has already opened all the material boxes at this time, just some cornerstones and basic materials, and he did not look carefully.

Harvest all the sea fish and freshwater fish, and throw them into the dug fish pond after the double trigger.

When he sold it before, he had people deal with it. This time he was going to sell live fish, at least the C-level ones should not be dealt with. There are too many, and there is no time to deal with them.

Xiao Yi returned to his bedroom, and Xiao Sheng had already run into his bedroom.

"I have a task today, pick all the edible fruits in the woods and send them to me. When it's done, there are two glasses of water to drink!" Xiao Yi said to Xiao Sheng very quickly.

"Squeak! (Really, I'll let my monkey monkeys move in right away! Xiao Sheng jumped up immediately.

Xiao Yi looked at Yi Tianqun, and all of them were discussing the topic of Xiao Yi selling high-grade food.

"Is this the first time that Yi Ranpin has sold food in large quantities?"

"This is the 6th time, on the 4th day, the 9th day, the 20th day, the 28th day, the 38th day, and today, the 48th day!"

"Lying on the grass, the upstairs is awesome, even this is counted!"

"Looking at this rule, it seems that every ten days, the boss will sell food to the outside world!"

"Can you get so much food in ten days?"

"The world of the boss, you definitely can't guess, it's better to prepare the cornerstone honestly!"

Xiao Yi looked at everyone's discussion and said: "Hello everyone, today's sale is not just food, in addition to grade food, there are weapons, clothes, etc. Everyone should plan their own cornerstones, the weapons withdrawn this time are against defense. Your own island is very useful!"

Seeing Xiao Yi's message, everyone immediately became excited.

"The big guy is awesome! Even the weapons are out!"

"The bosses all said that this weapon is very important for defense, so it must be taken, safety first!"
