No jokes here

With the decline of Nian's physical strength, soon, a large pool surrounded by stones appeared in front of Lin Qian'an.

This pool is circular with a diameter of about ten meters, and it is filled with boiling water.

Quality Improvement Pool [White]

Quality: best

Skills: Quality Improvement

Durability: 156/156

【Explanation: Put everything in it and cook it! 】

[Quality Improvement: Items soaked in the quality improvement pool will increase in quality over time. (Note: The current quality improvement pool can only improve the quality of gray and white items.)]

Chapter 293 Earthquake Beast, a Savage Way

When Lin Qianan saw this building, his expression was very exciting.

If this thing can be used to improve the quality, will he not have to work so hard to improve the quality of the item in the future?

Immediately, Lin Qian'an threw a bunch of low-quality, ordinary, and excellent processing materials and excellent-grade tools into it, and at the same time threw away a top-quality material.

These things are rolling in the quality improvement pool, and each item has a progress bar above its head showing [quality improvement].

Of course, except for that top-quality material.

Lin Qian'an knew in his heart that this thing can only be promoted to the highest level, and then it will not work.

So he backhandedly salvaged the top-grade material again.

Since there was still some time left for the progress bar, Lin Qianan simply built a new quality improvement pool next to it.

After building five quality improvement pools, Lin Qianan stopped.

Each quality improvement pool is full of materials.

If this thing can really improve the quality of all the items to the highest level, it will probably be the next most expensive building.

Following Lin Qian'an's observation, the materials in the first quality improvement pool have all been upgraded to a higher quality.

The water inside was still boiling.

Lin Qian'an calculated the time, and it took about an hour to improve a quality.

Immediately he looked at the consumption of durability again.

Then the corner of his mouth twitched involuntarily.

The materials and tools he threw in this pool add up to more than 30 pieces. Now, after a wave, the durability is directly reduced by half.

If he wants to mass-produce top-quality materials or equipment with the quality improvement pool, it may not be so easy.

But compared to the past when we could only rely on probability, it is much better now.

Lin Qian'an took out the materials and tools that had become top-quality, put some high-quality materials in them, and immediately started to build a new quality improvement pool.

There is no limit to his lack of top-quality materials, so the more quality improvement pools, the better.

After building fifteen quality improvement pools, Lin Qianan stopped.

Although the ultimate boiling water is easy to gamble, but Nian's physical strength is also depleted, isn't it?

So Lin Qian'an didn't intend to become fat with one bite.

Looking back, Lin Qian'an used his thoughts to build black iron again.

Metal materials are the key to unlocking the technology tree.

Lin Qian'an had tried to build a steam engine with wood or stones before. Even if the best skill was used, the durability would drop like a leaking pot. Even if it could be used, it wouldn't last long.

So if you want to unlock the steam engine, you have to unlock the material technology first.

The amount of black iron quickly accumulated to a certain level, and the blueprint of the small steam engine, Lin Qian'an, had already been unlocked.

[Simple Steam Engine Blueprint [White]: Processing Wood*26, Processing Stone*20, Processing Charcoal*17, Water*14. (Construction consumes stamina: 38)]

Just change the two materials of processed wood and processed stone into black iron.

Lin Qian'an clicked Add Materials, replaced all processed wood and processed stone materials with black iron, and then added processed charcoal and water, and immediately started construction.

Boilers, chains, gas pipes, pistons... As the construction continued, a small steam engine soon appeared.

Simple steam engine [white]

Quality: Normal

Durability: 622/622

[Instructions: Bring the water to a boil and try. 】

Start, preheat, and soon the water will boil, and the high-pressure steam will start to push the piston to drive the machine.

Accompanied by the sound of the piston running continuously, Lin Qian'an also showed joy on his face.

By the way, this thing actually has an achievement, and it has already been obtained by Lin Qian'an.

[Reminder: You have already unlocked the achievement [Steam Age], obtained rewards, item upgrade card [White]*1]

[Steam Age: Research out machinery that utilizes steam. (Note: This violent roar is really intoxicating!!)]

This white item upgrade card plus the item upgrade card obtained from the [Wind Age] achievement, now Lin Qianan already has two white item upgrade cards.

In other words, he can directly upgrade two green level items.

However, the achievement rewards are one less item, Lin Qianan dare not use them indiscriminately, and must use them in key places.

Just like upgrading the library level before.

The two gray item upgrade cards at the beginning were used by him to upgrade the stone ax and arrows. Now that I think about it, it was really a waste.

With the steam engine made of black iron, Lin Qian'an didn't need to instruct the artisans in the village, they spontaneously began to study various machines that use the steam engine.

Cities soon had steam cars for transporting goods.

Even in winter, you can hear the roar of steam engines.

At this time, Lin Qian'an was building roads and railroad tracks to pave the way for steam locomotives in the future. At the same time, he was also asking the craftsmen in the village to study generators.

No matter how useful the steam engine is, the energy source of electricity is always indispensable.

...

At this point, time began to speed up.

It was the second year of the founding of the country.

The first steam locomotive was put into trial operation, and it began to travel hundreds of miles, pulling and transporting goods. At the same time, the country also initially developed machinery that uses electricity.

Therefore, Lin Qianan unlocked a new achievement.

[Reminder: You have unlocked the achievement [Era of Electricity], get rewards, item upgrade card [green]*1. ]

[Electricity Age: Research a machine that uses electricity and run it for 10 minutes. (Note: The power of thunder and lightning!)]

This just means that there is electricity, but Nianguo is still very backward in the use of electricity, and even the conductive materials are forcibly obtained through the skill granting book.

Along with the continuous development of Nian Kingdom, the area covered by its influence is getting bigger and bigger, and the surrounding tribes began to be absorbed one by one, and the population also began to expand.

This year, after absorbing members of the three tribes, Niancheng finally broke through the population of tens of thousands.

At the same time, Nian Guo found a new metal vein and began to smelt other metal materials.

I read the country for three years.

Oil was discovered, coal mines were also discovered, and a series of technologies were pointed out by the hackers.

At the same time, the population of Nian Country exceeded 3 people, and Nian City was finally full of people.

However, this population is still too small.

Five years after the founding of the country, the first aircraft capable of flying in the sky was born with the accumulation of various top-quality materials.

[Reminder: You have unlocked the achievement [Fly to the Sky], and you will get the reward, Anti-Gravity Badge [Blue]*1. ]

[Fly into the sky: stay in the sky for 10 minutes. (Note: It's cold here....)]

[Anti-gravity Badge [Blue]: After wearing it, you can get rid of the gravity of the planet. ]

With this badge, it became easier for Lin Qianan to explore the world.

Just ask Nian to wear the badge and start traveling in the sky and exploring the map.

Soon, Lin Qian'an saw a new tribe, and also discovered all kinds of strange birds, beasts, fish and insects.

Those new tribes were absorbed by Lin Qian'an as a population, and birds, beasts, fish and insects were domesticated if they could be domesticated, fed if they could be fed, and studied if they could be studied. Anyway, there is no shortage of them.

Read the ten years since the founding of the country.

Today, Nianguo has a population of [-] and owns three cities.

The technology tree has also broken through to the point where electricity can be easily utilized.

Nian people no longer worry about food and clothing.

But after all, the population is still too small, which limits the speed of development.

Because there is no shortage of food, Lin Qian'an is also starting to spread extraordinary knowledge.

Among them, only the three extraordinary methods of martial arts, witchcraft and weapon cultivation can be spread, and the rest are not acclimatized.

And even these three have some small problems.

For example, in terms of martial arts, there is no way to practice internal strength, and the tendons and dantian are different, so you can only improve your qi and blood to temper your body.

As for witchcraft, the mental strength improved by meditation is quite slow.

Utensil repair has the widest adaptability, but there is also a small problem, that is, accumulating utensils consumes more energy and spirit, and the effect is worse, and utensils cannot breed spirituality.

However, although spirituality cannot be born, artifacts can improve their strength and quality through cultivation.

Because of this, a new profession appeared here in the "Yunqi Zhenjing", called Yunwu Master.

Specially cultivate items to improve the strength and quality of items.

It is a bit similar to the quality improvement pool, but it is less efficient, but it has more possibilities to improve the item level.

By the way, Nian is now at level 28, and Lin Qian'an has also raised Nian's power attribute and spiritual attribute to more than ten points by relying on the super food that he spawned.

And got two new skills.

[Strength Explosion: Consume a lot of stamina, increase strength by 1% within 50 minute. ]

[Exploration: Use mental power to cover the surrounding [-] meters to investigate the situation. (Note: The detection range increases with the improvement of mental attributes.)]

What I want to say here is that the temporary attributes blessed by buildings such as cities or buffs from foreign objects will not have skills.

Read the 15th anniversary of the founding of the country.

With Lin Qian'an's strong encouragement, the new population is very considerable.

At the same time, he also saw the sea.

The endless ocean made Lin Qianan full of desire to explore.

Without even thinking about it, Lin Qiannian directly organized a group of people to start exploring the ocean.

As soon as the ship is built and enters the sea, an achievement is unlocked.

[Reminder: You have unlocked the achievement [Age of Sail] and received a reward, sailing blueprint [White]*1. ]

[The age of sailing: build tools that can sail on the sea. (Note: Towards the boundless sea!!)]

[Sailboat Blueprint [White]: Processing wood *300, processing cloth *150. (Construction consumes 500 stamina)]

Seeing this drawing, Lin Qian'an couldn't help being a little speechless.

It's too late! !

Wait for a while, he has already created a nuclear-powered battleship, isn't it funny to give him a sailboat blueprint now?

But after thinking about it, Lin Qianan still built a sailboat and took a look.

How should I put it, in the ranks of wooden boats, it is not bad, but it is not bad. Now that the country's technological level is high, this thing can only be kept in museums.

Maybe if they are all built with top-quality materials, you can take a look.
