"Ding~ You successfully made a bow and arrow, and the technology point is +1."

"Ding~ You successfully made a file, and the technology point is +1."

"Ding~ You write the first word, technology points +10!"

"Ding~ You recite the multiplication formula, and the technology points are +10!"

……

In three days, Chen Li tried his best to make small inventions and made a bunch of messy things.

Coupled with the two most widely applied disciplines, writing and mathematics, the science and technology points have been raised from 62 to 99.

And these three days are also the most difficult three days for the novice tribe primitives.

There's no way, the shame is too strong, and there are no clothes to wear, so you have to come back with a red face when you run out to pee.

Sometimes I happen to collide with other people, and I am so ashamed that I want to dig a pit and bury myself.

The primitive people of men and women who used to exercise vigorously every night also restrained their physiological needs very well this time.

In the past three days, Chen Li has only seen less than 30 incidents of primitive people running to other people's houses while it is dark and making faint strange sounds.

In the past, when it was dark, people gathered around the campfire to have a party!

In the entire tribe, except for Chen Li, the one who goes out most often is the Queen of the Bay.

She was the only one of them who already had clothes to wear.

…… Although it was only a pair of scallops and leaves.

However, with this advantage, she is close to Chen Li.

The small invention "straw hat" was developed by her first to make a semi-finished product, and then Chen Li successfully plagiarized it.

On this day, the sun was blazing at noon.

The Queen of the Gulf came to meet Chen Li again, planning to attack this tall, handsome, intelligent and powerful man.

Chen Li is thinking about making another small invention and making up 100 points of science and technology.

At this time, the brain is a little insufficient, and I am at a loss.

Seeing that the queen of the bay was coming, he said: "It's just in time, help me come up with ideas, see what everyone's shortcomings are, and I'll create." ”

The Queen of the Gulf is no longer surprised by Chen Li's "invention".

Although they all call him a "great inventor" and "the first ancestor of humanity" behind his back, he feels very admired when he thinks about it.

But on the surface, you still have to restrain yourself and show a normal attitude, so as not to be too far apart from each other and lose the opportunity to pursue him.

Hearing Chen Li's question, the Queen of the Bay tilted her head and thought about it, then said, "Big Chief, can you make something to help everyone fix their hair?" Many people have long and messy hair, which is very difficult to work. ”

Hair?

Chen Li's eyes lit up.

"Yes!"

As soon as the Queen of the Gulf's speech ended, his thoughts came.

The hair is long and messy, and the washing, cutting and blowing ...... Isn't it over with a one-stop shop?

He could make a pair of scissors and then a comb and get that done.

But...... Scissors are a bit troublesome, and it is not convenient to make them for the time being, so I can replace them with knives.

Get a comb to easily take 1 technology point, make up enough 100 integers, but a careful wish.

"You wait, I'll do it right away."

Chen Li said a word, and ran to the wood pile next to him to find a piece of wood with good texture.

Then, with the sharpest bone knife, the wood is cut into thin slices of less than 1 cm and sanded until smooth.

Then he took a small bone carving knife, slowly cut out the shape of the comb, and then smoothed it with a small stone file......

In less than 2 hours, a simple wooden comb was made.

"Ding~ You successfully made a comb, and the technology point is +1."

The system prompt sounds.

Chen Li was satisfied, and casually threw the comb to the Queen of the Bay, "Oh, the first comb in history, let's play with it." ”

"Uh, big chief, this...... How to use it? The Queen of the Bay asked puzzled, playing with it for a while.

But Chen Li didn't answer her.

Because the system prompt is not over yet!

After the technology point is +1, the system prompt continues to broadcast.

"Ding~ Since the host technology points have reached 100 points, the technology mall function is on!"

"The Tech Mall can be exchanged for a large number of practical tools and heritage stereotypes, which can be exchanged for technology points."

"Once redeemed, it will not be returned."

Then Chen Li felt a flower in front of him, and a translucent "mall" interface appeared in front of his eyes.

A row of item icons appeared in the mall, all of which he could currently redeem.

Flint: 5 science points/piece

Hemostatic ointment: 10 technology points/piece

Bronze Knife: 20 science points/piece

Big iron pot: 30 technology points/piece

Seasoning set: 50 technology points/piece

Inheritance stereotype (unidentified): 100 technology points/piece

Inheritance Stereotype (Level 1 Mathematics): 100 science and technology points/piece [limited to 1 piece]

Inheritance Stereotype (Level 1 Farming): 100 technology points/piece [limited to 1 piece]

There are a total of 8 items that can be selected.

There are also 2 gray icons, which are not redeemable for the time being, but are only for display.

Furnace Set: 500 Tech Points/piece [1 piece limit]

Inheritance Stereotype (Level 2 Shipbuilding): 500 science points/piece [limited to 1 piece]

After reading it, Chen Li was stunned.

Mall! This Nima is a mall!

"I can finally take the initiative to get items~"

Chen Li was moved to tears.

The task given by the system according to the mood has finally changed a little, and he can take the initiative to accumulate technology points in exchange for the things provided in the mall.

Although there are not many types of props, they are all very useful.

In particular, the unidentified inheritance stereotypes are unlimited for exchange.

It is...... The cost of tech points is a bit large.

He has been here for more than half a month, and on the premise of 0 science and technology, he has only accumulated enough 100 science and technology points.

As the number of inventions increases, it will become more and more difficult to obtain technology points in the future, and it is simply impossible to exchange them for advanced items worth 500.

"Exchange me a big iron pot!"

Chen Li excitedly began to exchange for props.

Hemostatic cream is a consumable, although the effect is magical, but there is no need to store it in advance, just change it when you need it.

Flint and bronze knives are not in great demand for the time being.

The seasoning set is too extravagant, it costs a full 50 points, and I am reluctant to change it.

The big iron pot is the most practical thing, which can not only be used to cook food, but also can be used to boil seawater for salt, and the practical value is super high.

And this thing is iron!

30 technology points can be exchanged for a practical iron tool, which is simply a system benefit.

As for the stereotype of inheritance, there is a demand for it, but the people of the tribe have just obtained the [Clothing] inheritance, and their mentality has changed somewhat, so they will not exchange other inheritances for the time being.

Especially [Farming] is the same as the side task [Farming] that Chen Li has at hand.

After the side quest is completed, 2 inheritance stereotypes will be given, and maybe they will be identified at that time, and it may not be possible to give a farming technique directly.

"Ding~ The exchange is successful, you get a big iron pot!" System prompts.

A new large iron pot appears in the warehouse, and at the same time, the technology point -30 has become a 70 balance.

Chen Li was overjoyed, and was ready to take out a big iron pot and have a seafood feast on the spot!

At this time, the queen of the bay next to her was puzzled: "Big chief, big chief? Why did you suddenly stop talking? You haven't taught me how to use this thing yet! ”
