Although exercise can also improve attributes, the efficiency is too low, and Lin Qian'an expressed disdain for it.

With that little time, he would have probably gained higher attributes by betting on a top-notch dish.

Taking some time off, Lin Qian'an came to the river where the Cook tribe usually draws water and fishes.

The river here is very fast, so it would be suitable to build a waterwheel here.

So Lin Qian'an began to describe the waterwheel to the Cook craftsmen, and at the same time guided them to start making it.

Since Lin Qian'an just wanted the drawings, the craftsmen didn't need to be too detailed, just make sure it could run.

More than a dozen craftsmen worked overtime, and in less than half a month in the game, Lin Qian'an saw the results, a waterwheel that was more than six meters high and could rotate in the river.

Lin Qian'an used her thoughts to go forward and collect the drawings, and then started construction.

The warehouse is filled with enough materials, and construction starts automatically with a click of the mouse.

He was quite lucky, and he actually won an excellent quality waterwheel for the first time.

Because the drawing itself includes installation, the waterwheel will already be running when the construction is completed.

At the same time, a prompt also appeared.

[Tip: You have unlocked the achievement [Water Power Age], received rewards, item upgrade card [White]*1.]

[Water Power Age: Constructed objects that utilize water power. [Note: This is the power of water.]]

Lin Qian'an scratched his chin. If this can be considered an achievement, then does using the power of the wind count?

He made a decision to go back and build the windmill when things here were over.

Immediately, Lin Qian'an took out the skill granting book using Nian and began to assign skills to the waterwheel.

Not long after, Lin Qianan obtained a functional skill.

[Speed ​​up the speed: The water wheel rotates faster.]

Lin Qian'an was a little stunned when she saw the waterwheel turning rapidly at the edge of the river.

Sure enough, having skills and not having skills are two different things!

With this thing, it can be used to collect water or irrigate farmland, or it can be used to use the power of the waterwheel to do some simple industrial production. It is a good thing.

But those are things that will happen later. For now, Lin Qian'an's attention has been attracted by the newly obtained item upgrade card.

He has used this thing twice and knows its effect.

It was a bit wasteful to use axes and arrows before, but now thinking about it makes Lin Qianan feel a little sad.

Of course, such a good thing must be used in key buildings to make it worthwhile.

Lin Qian'an immediately thought of the library.

The level of the skill-granting book will increase with the level of the library.

Therefore, upgrading the library is definitely the most cost-effective option.

However, this library is currently not in line with Lin Qian'an's wishes.

Because this library is only of ordinary quality, it only has a [Concentration] skill by giving the book a skill.

Such an important building must at least be of the highest quality.

So Lin Qianan immediately prepared to build a new library.

This time, Lin Qian'an decided to use the best processing materials to make the library.

That is, "processing wood".

Building this thing requires a bit of stamina, but it's very fast. Basically, you just have to keep clicking the mouse.

After spending more than 1,200 stamina, you can probably get three to five top-quality processed wood.

The number of processed lumber required to build a library is eighty-six.

In other words, if you don't rely on loading files, you will need at least 20,000 ordinary wood to get enough materials.

Lin Qian'an touched his chin, calculated the time cost, and calculated the amount of wood currently stored.

The tribe has actually always had a surplus of wood and other materials, and now has more than a dozen warehouses of wood stored. Most of the nearby forests have been cut down.

It’s not like we don’t have 20,000 yuan worth of wood. The question is whether it’s worth it.

In the end, Lin Qian'an decided to directly spend 20,000 yuan of wood to bet on this library.

Reading files is a waste of time. If you really want to get these eighty-six top-quality materials, you may not be able to succeed tomorrow.

But if he directly gambled with 20,000 pieces of wood, he would have finished it in ten minutes. It goes without saying how much easier it is.

As a result, all the wood stored by the tribe was quickly processed into processed wood by Lin Qian'an's mind.

Among them, there are the most inferior and ordinary ones, and there are also many excellent ones. There are probably thousands of excellent ones, and there are only more than 180 top-quality processed woods.

These top-quality processed woods all have their own skills, either to make the material durable or to give the material some special properties, such as waterproofing and high temperature resistance.

Lin Qian'an immediately started building a library using eighty-six top-quality materials.

They are all made of the best materials, and there is nothing to say about the construction. It was a success in one go.

Library【White】

Quality: top quality

Skills: Concentration, Comprehension, Intermediate Durability, Invulnerability to Water and Fire

Durability:1500/1500

[Explanation: This is a library that will make your study easier.]

[Concentration: It is easier to concentrate when reading in a building.]

[Integration: When reading books in the building, it is easier to understand the meaning.]

[Intermediate durability: durability +1000.]

[Invulnerability to water and fire: The building's resistance to water and fire becomes higher.]

A smile appeared on Lin Qian'an's face, it was not in vain to waste his eighty-six top-quality materials!

Lin Qian'an took out the skill-conferring book and placed it directly in the new library.

The next moment, where the skill-giving book was placed, a holding platform was automatically generated. The skill-giving book floated on it, and the gray surface gradually turned white.

[Skill Granting Book [White]: You can use this book to grant skills to gray and white grade items. The cooling time is one day. [Currently available: 2/2] (Note: Skills cannot be assigned to items that already have skills. When granting skills,

There is a high probability of obtaining primary skills, and a small probability of obtaining intermediate skills. The level of the skill-granting book will be improved as the level of the library increases.)]

The white skill grant book has one more opportunity to grant skills, and there is a small probability that intermediate skills will appear.

Lin Qian'an was very satisfied with this change, and he had even begun to look forward to what the next level of skill grant book would look like.

Take out the "Item Upgrade Card [White]".

Click on the library, and as a burst of light flashes, the library will be upgraded.

Library【Green】

Quality: top quality

Skills: Concentration, Comprehension, Intermediate Durability, Invulnerability to Water and Fire, Photographic Memory, Elementary Mental Strengthening

Durability:5500/5500

[Explanation: This is a library that will make your study easier.]

The grade after white is green.

After the library became a green-level building, its durability was directly increased by 4,000, and it gained two additional skills: "Photographic Memory" and "Basic Mental Strengthening".

Needless to say, photographic memory means that you can have photographic memory when reading books in the library.

But primary mental strengthening is extraordinary.

[Primary mental enhancement: When in the library, mental attributes +10.]

What is this concept?

Now the mental attributes of Nian are only 5.9.

A direct bonus of ten points is extremely exaggerated!

If you stand in the library and build an item, even a large building such as a waterwheel, it will probably take seconds, right?

In addition, what is the concept of ten spiritual attributes?

Is it okay to let your thoughts go out?

However, if you only strengthen your mental attributes without physical support, you may not be able to sustain your thoughts for long.

After calming down, Lin Qian'an focused on the skill-giving books in the library.

That thing has now changed from a white book cover to a green book cover.

[Skill Granting Book [Green]: You can use this book to grant skills to gray, white, and green grade items. The cooling time is one day. [Currently available: 3/3] (Note: Skills cannot be assigned to items that already have skills. Grant
