Wielding the stone axe, Yu Fei was not idle, he took a shovel and a stone pickaxe and began to dig bamboo shoots.

Compared with meat that is difficult to obtain, although bamboo shoots are vegetarian, they are also food, and if they are food, they have great value, not only can they be kept for their own food, but they can also be placed on the trading platform in exchange for the materials they need.

On the trading platform, Yu Fei saw someone selling iron ore, and he dared to ask for 10 catties of edible meat for a pound of iron ore, which was really a lion's mouth.

However, compared with the easily obtained sources of fire and water, iron ore is indeed more difficult to obtain, so the price on the trading platform is generally higher.

Compared with the Stone Age, the Iron Age is a qualitative leap, and the efficiency can be increased several times, so for iron ore, Yu Fei is imperative.

He didn't have that much edible meat to exchange, so he had to dig bamboo shoots in exchange for iron ore.

Dig bamboo shoots when you're tired, cut bamboo when you come to rest, sometimes encounter bamboo rats and other animals that come out to feed, Yu Fei will also choose to shoot a few arrows, and when the sun sets, Yu Fei has upgraded the "felling" to LV2, but it's a pity that digging has not increased Yu Fei's ability.

[Slashing Lv2 (25/1000)]: You are already a master of slashing, +10% slashing speed and -1% slashing cost.

At LV2, you need to cut down two bamboos to gain 1 proficiency point, and the difficulty of leveling up has increased a lot.

Bringing back three or four hundred bamboo shoots, one hundred and sixty bamboos and two fat bamboo rats on the trading platform, Yu Fei took advantage of the sunset, humming a tune in his mouth, and went home leisurely.

The night is quiet, but for nocturnal creatures, it's their stage.

All kinds of insects and small animals became more and more with the intensity of the night, and there was even a huge centipede with a length of five or six meters crawling in front of Yu Fei's feet, Yu Fei was very scared at that time, but fortunately he had good concentration, he was definitely not stunned, he was motionless, and the centipede crawled quietly in front of him, and the two were safe.

After that, Yu Fei quickened the pace of going home, trotting all the way, it was supposed to be a twenty-minute journey, but Yu Fei only took five or six minutes to return to the safe house.

At night, it was pitch black in the safe house, it could be said that he couldn't see his fingers, and there was only the sound of Yu Fei's breathing in the quiet safe house.

After a long time, Yu Fei's breathing had smoothed out, but his eyes still couldn't see his surroundings clearly.

When the safe house was opened, the moonlight shone down, and there was light in the safe house, although it was still dark, Yu Fei could already see it clearly.

By the moonlight, Yu Fei began to light a fire and cook.

In fact, Yu Fei also had no desire to cook, and the exhaustion of his body made him not want to move anymore, but his hungry body still made him insist on heating the food left at noon.

Although it was just unseasoned leftovers, at this moment, Yu Fei felt extremely satisfied, as if he had eaten the most delicious food in the world.

Although it was only hot food, it still allowed Yu Fei to gain 2 points of 'cooking' proficiency.

After eating and drinking, Yu Fei had no desire to move at all, and roughly cleaned up the kitchenware and tableware, then closed the door of the safe house and lay on the bed.

But after lying down for two seconds, Yu Fei stood up suddenly, not because he was high-spirited and wanted to improve his proficiency, but because the bed board was too hard, he was so panicked that he really couldn't lie down.

Then the bright light of the virtual screen of the system, Yu Fei walked quickly to the workbench, which has the function of making bedding and mattresses, but it only requires a large amount of fibers, and it happened to be in the afternoon when Yu Fei cut down a large number of bamboos, and a lot of fibers can be extracted from the bamboo.

In the afternoon, one hundred and sixty bamboos were felled, and Yu Fei threw all of them into the workbench, all of which were made of fiber.

The fibers made of bamboo are hard, but the amount is huge, 160 bamboos, a full 28,888 fibers, and 36 of them are 'white' quality!

Compared with the mediocre quality of 'gray', the quality of 'white' has one more attribute!

【Fiber】:

Quality: White.

Attribute: Soft +1.2.

Serving Size: 1 serving (50g).

Note: Quite excellent fiber, which is the basic material for making clothes and props.

Each 'white' quality fiber has one attribute, 'soft' and 'hard', and the dots after the + sign are also inconsistent, but they are all between 1 and 10.

The attribute blessing brought by the 'white' attribute is worth a surprise, but what makes Yu Fei even more surprising is that the 'workbench' has been upgraded!

[Crafting Bench Lv4 (56/10000)]: Increases the chance of getting high-level items by 40%!

The workbench has been upgraded by 2 levels in a row, and it has reached LV4 in one fell swoop! The bonus is now 40%! However, it now takes 5 items to increase proficiency by 1.

However, these proficiency levels are nothing to Yu Fei at all, as long as he uses more workbenches, the proficiency can be earned sooner or later, and the ability to have a 40% more chance than others is a real bug!

There were 4 fibers with the attribute of 'softness' and 32 parts with the attribute of 'hardness'.

Fibers with the attribute of 'hardness' do not mean that they are very hard, like stones. Rather, it is said that its texture is on the hard side, the ductility is poor, and it is not soft.

Obviously, 'hard fiber' is not suitable for quilts, but is suitable for mattresses.

So Yu Fei took out 20 parts of white quality 'hardness' fiber and 80 parts of gray quality fiber to make a mattress.

At the time of crafting, the workbench also shows the probability of Yu Fei obtaining the quality of the item when crafting an item with white quality materials:

The probability of obtaining gray quality is 0.01%, the probability of obtaining white quality is 99.89%, the probability of obtaining blue quality is 0.0999%, the probability of obtaining gold quality is 0.0000999%, and the probability of obtaining purple quality is 0.0000001%.

[With the blessing of Workbench Lv4, your probability becomes: 0.01% chance of getting gray quality, 99.85% chance of getting white quality, 0.13986% chance of getting blue quality, 0.00013986% chance of getting gold quality, and 0.00000014% chance of getting purple quality.] 】

After reading it, Yu Fei's face was full of astonishment, this could even get low-grade items! It's really a pit! Fortunately, his ability only increases the probability of getting high-quality items, otherwise he would have cried.

Shaking his head, Yu Fei began to make mattresses and quilts.

【Hard Mattress】:

Quality: White.

Stat: Keep Warm +4.3.

Weight: 10 pounds.

Remarks: A slightly hard mattress, but good for the waist.

Although it was spring here, Yu Fei didn't feel how cold it was, so instead of making a thick quilt, he made a quilt with 4 parts of white 'soft' fibers and 6 parts of white 'hardness' fibers.

[Quilt]:

Quality: White.

Stat: Keep warm +8.5.

Weight: 1 pound.

Remarks: The texture is soft, skin-friendly, and has a good warmth effect.

Lying on the new bed, Yu Fei made a comfortable sound, this can be called a bed!

However, with a comfortable mattress and quilt, there was still a lack of a pillow, so Yu Fei made a solid pillow with 20 parts of gray quality fiber.

The reason why Yu Fei didn't use all the 'hard fiber', but planned to use it to exchange for iron ore.

Stone tools are not only inconvenient to use, but also inefficient, if there is iron, entering the Iron Age, Yu Fei's cutting efficiency will definitely go to a new level, and along with the 'workbench' proficiency can also be quickly improved!

Yu Fei first checked the information about white quality items on the trading platform, but it turned out that there was none, which made Yu Fei realize that this would be the first white quality item for sale, and it must not be sold cheaply!

But Yu Fei doesn't know the market either, and he doesn't know how to price it to get the maximum benefit. After thinking about it, Yu Fei remembered the 'auction platform' of the trading center!

【Fiber】:

Quality: White.

Attributes: Hardness +1.7.

Serving Size: 6 servings (300g).

Reserve price: 100 catties of iron ore.

Current Bid: 0.

Countdown to the end of the auction: 24 hours: 59 minutes: 59 seconds.

After some operation, Yu Fei put the last 6 white quality fibers on the auction table for auction, and then fell asleep.

He was too tired on this day, the amount of labor in a day was more than in the previous month, if it weren't for the motivation given to him by [Heaven Reward for Diligence], otherwise Yu Fei would not have been able to do so many things, he would definitely be like most ordinary people, doing nothing, spending this day in panic and hunger, but fortunately, he gained this ability!
