After spending five silver shells, Yi Fei bought a set of wood, a set of stones, a group of nettles, and a group of animal fat. The cloth is relatively simple, two parts of nettle can make a cloth, each part of 3 minutes 1 point of experience, easy to fly brush directly all the batch of points, 50 points of experience to hand.

"It takes five hundred points of experience to upgrade from level three to level four, so I'm afraid it won't take long to level up again."

You can only make one thing at the same time, which is converted into time, but it takes half a day to make this one. This saves Yi Fei a lot of time, according to the things sold by the trading house, there are no iron ingots, which means that everyone is estimated to be the highest level now, he belongs to the forefront of the world, even if those local tyrants spend more money to buy materials, it always takes time to make things, right?

Then there is the production of low-quality fuel, three parts of animal fat and one cloth, five minutes, and the experience is actually two points. The furnace only needed thirty parts of low-quality oil, and he put the rest in a wooden box to be used later when needed.

With all the materials ready, Yi Fei began to make the furnace, two hundred parts of stone, one hundred parts of wood, and thirty parts of inferior fuel disappeared from the backpack, and the furnace that took five hours to make was completed in an instant, and the experience skyrocketed by fifty points.

The furnace is a processing facility that can be arranged both indoors and outdoors to smelt various ores and wood to obtain secondary resources such as iron ingots, refined iron ingots, sulfur powder, charcoal, etc.

Yi Fei arranged the furnace in the flat ground at the bottom of the slope, but he disliked that the ground was not very smooth, so he quickly built another nine-square-meter house, which would be his studio in the future.

Somewhat frighteningly, the fuel used in the furnace turned out to be inferior fuel oil, one serving only burned for ten minutes, and it took five minutes to smelt an iron ingot. Yi Fei secretly said that he was fortunate to have the blessing of BUG, but ordinary players were only afraid of difficulties.

If you want to arrange the furnace on a large scale and increase the output of resources such as iron ingots, the cost is very high, and only the local tyrants supply the fuel, and ordinary players don't have so much energy to find so much fuel, and now that the service has just started, the basic resources are used less, so the price is cheap, and when the amount of basic resources soars in the future, the cost will be higher.

After looking at the experience points, it would take three hundred and six experience to upgrade to the fourth level, Yi Fei decided not to be conservative anymore, and used the remaining animal fat to make three parts of inferior fuel oil, and then he opened the trading house. Now there are no iron ingots in the trading bank, but there are a lot of iron ores, and they are very cheap, only three silver shells for a hundred copies.

After spending thirty silver shells to buy ten groups of one thousand iron ores, Yi Fei began to fill the furnace with inferior fuel oil and pile up iron ore. Iron Bars cost two parts of Iron Ore, and he gains two XP after smelting.

"Ding! Your level has been upgraded to level 4! ”

Yi Fei upgraded the moment he took out the five hundred iron ingots from the furnace, and even the experience of upgrading to the fifth level was only one hundred and sixty points, which was something that an ordinary player would take nearly two days in a row to complete, and he only took a few seconds.

Level 4 unlocks two pieces of equipment, cotton tops, cotton pants, and a combination lock. Each of these two garments requires 20 pieces of cloth, and each piece takes two hours to make, plus 2 points of defense. This is what Yi Fei needs the most, and it is really cold in the cool breeze on this night.

I bought a hundred more nettles from the exchange and quickly made the clothes. The top is a T-shirt in black, gray and white, and the bottom pants are only available in black, gray and beige.

After putting it on, I suddenly felt that the whole person was back in civilized society, but there was still a pair of shoes missing.

To be honest, the appearance of this combination lock is a bit abrupt, but Yi Fei thinks it is quite useful. After installing on the door, you can set a password, you don't need a password to enter, and others must enter the password, once you enter the wrong one, you will be deducted 20 points of blood because of electric shock.

The reason for the appearance of the coded door is that Yi Fei saw that the properties on the foundation, walls, and ceiling showed that the durability of these building components could only be destroyed by fine iron axes, machetes, and firearms. Therefore, there is this combination lock in the early stage, and you don't have to worry about being raided when you go out.

However, the manufacturing conditions of the combination lock are slightly more complicated, requiring 50 iron ingots, one electronic component, and the additional condition is power supply.

When he saw the power supply or something, he didn't think about it, this should be something that Lao Du said could only be opened by a drifting cargo box.

After getting these things, Yi Fei really couldn't bear it, so he made a sleeping bag and came out, got into it and fell asleep. Because the holographic helmet originally has an auxiliary sleep function, sleeping in the game is the same as the real effect.

When he woke up the next morning, Yi Fei grabbed his harpoon and ran to the beach, his hunger level dropped again, and now he was conservatively estimated to be almost two levels ahead of all the players. He took the time to get food without much delay, although there were coconuts in the trading houses, fish and even rabbit and bird meat for sale. But the price is quite expensive, he doesn't want to recharge the money anymore, and the money is still waiting to buy materials to upgrade.

After the long tide last night, the sea receded, leaving a lot of seafood, most crabs, but he didn't plan to eat it again, it was less meat, and it took a long time to grill.

A little outside, there will be shellfish and sea urchins, sea cucumbers, and more fish and shrimp in the puddles outside. Yi Fei was lucky, he caught two sea shrimp the size of half a palm, and a one-pound sea fish.

Yi Fei, who returned with a full load, touched a few coconuts from the coconut grove and went back, the morning on the island was still very cool, fortunately I got a set of clothes last night, and now this desert island life is on the right track.

Yi Fei took care of the shrimp and fish briefly, threaded them with wooden sticks, and roasted them on the fire.

Bang!

was roasting, suddenly a thunderclap suddenly sounded in the sky overhead, and the lightning illuminated the earth white, at this time Yi Fei noticed that the sky was already full of dark clouds, he thought at first that he had gotten up early, and the sun had not yet risen.

"Damn, this is the rhythm of the rainstorm?"

On this kind of small island the size of a football field, with an altitude of only seven meters, and like, encountering a rainstorm, Yi Fei's sense of security just rose in an instant, and he even felt that if the rainstorm was a little bigger, it would not be possible to flood the island, although a sudden rise in sea level of seven meters basically meant a doomsday disaster.

Click!

Rumble!

Yi Fei was still thinking about whether he had anything or not, and suddenly there was a terrifying explosion behind his head, which frightened Yi Fei to shake off the fish and shrimp, jumped up from the ground, and his two ears were buzzing.

He looked back and was stunned to see that a small half of the ceiling and walls of the house on the slope had been split, and the smell of burnt wood filled the air.

"Watts? I TM committed some kind of heavenly rules, and I was actually struck by lightning! Does the system know that I have taken advantage of the bug and is planning to hack me alive? Yi Fei secretly looked up at the dull sky.

After a while, a raindrop fell on his forehead, and Yi Fei hurriedly ran to the territory cabinet to repair it, he didn't want to turn the house into a fish pond later. Five hundred pieces of wood went down, and the repair time that would have taken half an hour was completed in the blink of an eye.

Back at the edge of the campfire, the two shrimps fell into the fire and were already burned, but fortunately there was still one fish left, which I picked up and patted and ate.
