Xiao Yi shook his head vigorously, throwing away the terrifying thought of someone observing them to survive.

If someone really observes, those people must be powerful, whether it is their own strength or technological strength!

If the strength is not strong, how can it be possible to design such a world rule!

In the face of those powerhouses who can design the rules of the world, I guess I am like an ant on the roadside, so let's live well first!

For Jiang Yuntian's breakfast, Xiao Yi sent more A-grade milk and said, "There is a lot of milk, and I can't finish it. Junjun is growing, so drink more!"

"Okay, thank you!" Jiang Yuntian replied.

After breakfast, Xiao Yi showered and changed again, and then said, "System, sign in!"

"Sign in successfully, get reward: equipment level upgrade card."

"Equipment Level Up Card: You can upgrade any piece of equipment by one level!"

Although the description of this card is very simple, it makes Xiao Yi extremely happy.

Now the question is, which device to upgrade?

Xiao Yi first ruled out those equipment that only had ordinary grades, that is, D-grade equipment. If such advanced cards were only upgraded from D-grade to C-grade, it would not be worth it!

It only makes sense to use at least A-level equipment!

Fully automatic fishing net, SS level, is enough now, and raising another level is not much for its own improvement.

Fully automatic toilet, SS level, the same reason, there is no need to upgrade.

Small radar detectors, SS class, are enough for now.

After looking around his equipment, Xiao Yi made a decision.

"Upgrade Class A water purifiers!"

Pure water is what Xiao Yi drinks every day, and high-grade pure water has a great effect, improving physique, promoting seed activity and so on!

The improvement of pure water level can definitely improve Xiao Yi's own strength, and it is beneficial to his own planting activities!

Before coming to the island monument, the island monument prompt was displayed immediately.

"It is detected that you have an equipment level upgrade card, please select the equipment you want to upgrade!"

"Class A water purifier!"

"Successful use, the water purifier level has been upgraded from A to S!"

"Water purifier (S grade): It can purify seawater into pure water. When the seawater supply is sufficient, it can produce 160ml of pure water per hour. The capacity of seawater in the machine is 5000ml and the capacity of pure water is 4000ml. It can be connected to a water pipe, but it needs to be Manual switch!"

After the upgrade, the production efficiency and capacity of the water purifier are doubled, and you don't need to irrigate the water yourself. You can connect to the water pipe. If there is no water, you can directly open it, and then close it when it is full, which is much more convenient!

"I don't know what this S-grade pure water tastes like?" Xiao Yi muttered, but he can only taste it after it has been purified!

After adding food to the chicken coop and cowshed, and adjusting the target of the fully automatic fishing net to the material box, Xiao Yi immediately hid in his apartment!

After eight in the morning, there is no way to stay outside!

Now everyone seems to be used to this state of hiding during the day and coming out to work after the evening.

"It's too hot!"

"Who made you get up so early, I need to sleep a little longer for the fish that was sprinkled in the middle of the night last night!"

"Wait, after so long, is there any gain?"

"Yes, a small fish 500g!"

"Digging a slot, you are too awesome! You actually caught a fish!"

"Damn it, I'm so **** tired that I'm almost collapsed, this fish is not enough for me to stuff my teeth!"

"That's finally a gain, isn't it? I also cast the net in the middle of the night yesterday, and I didn't see a single fish scale!"

"Hey, hurry up and rest, and wait until the evening to see if there are any material boxes you can get!"

Xiao Yi was blowing the cold air conditioner and had nothing to do. He took out the receiver of the small radar detector, looked at the signs of only a few material boxes around his island, and scratched it boringly.

He didn't cast the net until midnight last night, and now he is full of energy and has no intention of sleeping.

"what!"

Suddenly a red dot appeared from the border of the radar scan!

Xiao Yi immediately sat up: "Did anyone come to my side again?"

Zooming in on the interface of the radar detection receiver, I found that it turned out to be a medium-sized sailboat. The image scanned by the radar showed that there were many people on board!

"So many people?" Xiao Yi frowned and said, "But why are they wearing animal skins and feathers on their heads?"

The service of those people is very strange, and they don't look like people in the world before Xiao Yi!

"Could it be the indigenous people here?" Xiao Yi muttered, and then he became worried. If it was really the indigenous people here, it would be really troublesome.

The indigenous people here are definitely not few. In case of conflict, no matter how powerful one is, it is difficult to take into account all of them.

After all, there are a lot of Xiao Yi's efforts on this island!

That medium-sized sailboat was heading in the direction of its own island!

"What should I do?" Xiao Yi thought hard about the solution.

Suddenly the red dot on the receiver display disappeared!

"How could this be?" Xiao Yi was shocked to see that the screen became empty again, "How is it possible!"

He clearly saw a boat just now! How could it suddenly disappear?

At this time, Xiao Yi suddenly thought that someone had seen a big ship before, but no one believed it at that time!

"Could it be this kind of big ship?" Xiao Yi muttered, "It seems that this world is getting more and more complicated!"

Xiao Yi walked to the island monument and sent a message to the three of Su Wan.

"Have you ever seen a big ship?" Xiao Yi asked.

"Huh? No, there are only material boxes around me every day, not even marine garbage!" Su Wan replied.

"I haven't seen it before!" Yuan Nong replied.

"No, what's wrong?" Jiang Yuntian asked back.

"I saw a big ship here, but it disappeared instantly!" Xiao Yi replied.

Jiang Yuntian was stunned for a moment, and then said: "There was also a survivor who said he saw a big boat before, but he just lowered his head and looked up again, and the boat was gone. At that time, everyone thought he was lying! What you saw would not be The same boat!"

"I'm also suspicious of this!" Xiao Yi replied, "And I don't think that boat was made by us survivors!"

"What do you mean?" Jiang Yuntian asked with a frown.

"I saw that the people on the boat were wearing animal skins and feathers on their heads. They are probably the natives here!" Xiao Yi explained.

"What! There are still indigenous people here?" Jiang Yuntian was also shocked!

Xiao Yi nodded and said, "And there are quite a few of them!"

Jiang Yuntian did not doubt Xiao Yi's intelligence, but frowned and said, "If we are discovered by the aborigines here, it is estimated that it will be difficult to coexist peacefully!"

Xiao Yi replied: "I think so too, so now we must not only survive, but also improve our defense!"

"It's better to be able to hold a group!" Jiang Yuntian said.

"That's right!" Xiao Yi replied, and now he desperately hopes that Su Wan and the others can come to his island as soon as possible!
