Lu gently and perfectly (and didn't) suppress the urge to go up and rob again, and then killed the Qinglu tribe and pulled out the big city that was training the new patrol.

"What is a Power Stone?"

"Power stones, why do you suddenly ask this?"

"A tribe has come to Liubao to trade power stones. Lu said lightly and simply.

"Power stones are actually just a kind of ore, and the production is very scarce......"

Ayutthaya said slowly.

The Power Stone is full of energy, which is not simply life force, there are many impurities in it, but it can be used by a warrior with natural abilities after combing and filtering.

There are naturally very few stones like this that are naturally full of energy, and the few veins that are firmly controlled by the kingdom are firmly controlled, if this is the case, the impact of the scarce non-renewable energy is very small, who taught them to be less, but the energy stones can be recycled.

The energy stone full of energy is green, because there are impurities and mixed with other colors, there are colorful, there are also mixed with black, black, gray and gray dirty things, when it is exhausted of energy, it becomes very pure, crystal clear and particularly beautiful, at this time the energy stone can be re-infused with life force.

Theoretically, every innate ability warrior can infuse life force into the power stone, but the process is very depleting, for example, a person has a hundred life force, but he can only store it in the power stone in the end, maybe only thirty or forty parts.

There is a kind of person who specializes in charging energy stones for a living, this kind of person is generally the lowest level of the innate ability warriors, and the ability is useless, but it is a natural ability warrior, and it is too wasteful of resources to waste it, so let them store the life force they don't need into the energy stone and give it to those who need it.

Over time, because there are too many impurities in natural gemstones, they cannot be used directly when they are mined, so the power stones circulating on the market and mentioned in people's mouths are artificially stored by default. And because of the great loss of artificial storage, and the need for the precious carrier of energy stones, the price is still extremely high, and it is basically only circulated in the hands of the strong and powerful.

"The power stone can quickly replenish the life force, which is very beneficial for practice and improving ability, and it can also save lives in critical situations, and there is also a saying that if a female warrior can always absorb life force to raise a fetus when she is pregnant, the child may inherit the mother's ability after birth. ”

Lu lightly widened his eyes: "Isn't the ability of human beings only to be obtained from animals and plants?"

"That's generally the case. ”

So there's an unusual situation, right?

Why didn't Mr. Wu tell her?

Then think about it, it seems that there is no need to tell her, right? Wu always left in a hurry, and many things were still instilled into her by the last stream of brain, and it was also due to her good memory and high understanding.

Anyway, she understood that everyone wanted this power stone, and this big moon tribe happened to be not qualified to come into contact with the power stone, so they wanted to make a deal with Liubao.

However, if there are really energy stones that can be traded in batches, it is better to use them to train subordinates, or to trade with people who are also powerful, there will be more and better things that can be obtained, and the food of the Dayue tribe is so rare for her.

Lu thought lightly, feeling a little helpless, although she knew what the power stone was, but she didn't ...... Huh, wait.

Lu lightly suddenly perked up.

"What's wrong?" asked Oshiro.

"Suddenly remembered that the White Salt Tribe should have power stones, I'll take a look, you can get busy." Lu Qing then rushed back to the White Salt Tribe in a hurry.

Although it doesn't feel so tired, it's also very tiresome to fly around all the time, and Lu gently wants to have a faster and more comfortable way of transportation.

The water ability had already found Liu Zhou's body at this time, and at the same time, it was also estimated that the unearthed ability had taken away Liu Bao, they were angry, anxious and hateful, and they were out of proportion, Lu Qing took the opportunity to search, and found the energy stone in their respective tents.

There are a total of thirty-seven pieces, the size is different and the shape is irregular, but they are basically the size of a palm, and the weight is not light, most of them have used up the energy and become crystal clear, like crystal, and two are green, one is dark green, and one is light green, Lu lightly guessed that this has something to do with the energy inside.

She swept the thirty-seven energy stones into the space unceremoniously, ran to no one and tried it, the life force of the energy stones is very pure, there are no impurities, and the second is very gentle, and it can be completely adapted after absorption, if she can have a few energy stones during her recuperation, the recovery from the injury will definitely be much faster.

It's a good thing.

She tried to pour the ability into the power stone, the first few times it was very difficult, but gradually mastered the doorway, there are many holes on the power stone, which are usually closed, and can only be opened by activating with life force, and then it is not easy to pass the life force through these holes that are no bigger than the thickness of chopsticks and smaller than a toothpick.

Pouring a transparent energy stone into dark green, she stopped and found that she was sweating, and her spirit had been tense, which was too demanding for the control of the life force, and a distraction would get the life force out of the power stone.

She looked back and forth at this dark green dark green exuding a deep and mysterious brilliance is a power stone, and estimated that the life force of her physical energy was reduced by nearly half, and her wear and tear was about forty percent, which was not as high as Dacheng said, and it should have something to do with her controlling it well.

Practice a few more times, and this wear and tear can be reduced after becoming proficient.

So, is this business a good deal?

The answer, of course, is that it's a great deal!

With this half of the energy, she will fully recover in about a day, but this piece of energy stone is valuable, and it can be said that there is no profit!

Especially now that I'm idle every day, isn't it good to create some income?

She went to chase the Great Moon Tribe again with great dignity, and there was a delay of two days in the middle, the Great Moon Tribe couldn't go far on two legs, Lu gently chased them in the direction they left, and found them two hours later.

This time she didn't restrain her breath, sitting on a huge big white, and she couldn't restrain it, she adjusted her breath a bit, and maintained it in the state of an ordinary natural ability warrior, what is ordinary, just compare it to a few of her subordinates. Now she's got a good idea of hiding and camouflage.

"What's flying in the sky?"

"It's a person, and there's a person sitting on it!"

"It's not good, it's a natural ability warrior!"

The Dayue tribe was startled, and immediately stopped advancing to line up for defense, the team leader and a young man stood at the front, Lu lightly swept his consciousness, and determined that these two were also innate ability warriors, and the team leader was almost the same as the one she was now after disguise, and the young man was almost, on par with that earth ability.
