Li Du slowly woke up, and in an instant felt something very unusual nearby.

The eye's vision seemed to have expanded a lot, and the texture of the very small talismans above the forbidden array was all clear and easy to see, so that the sufficient spiritual power in the vicinity seemed to be all-encompassing.

But, it's not just spiritual power. Suddenly he realized that he could see it himself.

He directly realized that he could actually see it inside. The true power in his body is like a picture, and every wisp of it can be seen so clearly that he can see it thoroughly.

He seemed to be able to see everything, everything was clear.

This kind of feeling is unheard of.

But very quickly, he realized that this was not "hope", but the feeling of spiritual consciousness.

When an immortal cultivator reaches the spiritual building period, the best thing to speed up is spiritual consciousness, which is not limited to the body, but can be dispersed outside the body, and everything in the vicinity is contemplated in the heart. The spiritual sense is more and more perceptual than the eyes and ears, and with the increase of the level, the spiritual sense can feel hundreds of miles away. Although he can only maintain a radius of ten meters now, and may be very tired, Li Du is already satisfied.

It's good to look at yourself.

Inspecting his body again, he was even more surprised to find that the qi pool and veins had expanded to more than the original four times.

This proves that his mana power store will increase by four times, and the faster he can use his mana, the greater his strength.

This is the Spirit Building Period, and it is really much stronger than the Qi Condensation Period.

Li Du sighed, although the bones of his body still had the pain just now, but all of them were very worthwhile.

He didn't even know that this was because of his spiritual building experience, which would be much more difficult than that of ordinary immortal cultivators, so the more he obtained, the more he obtained, the more ordinary immortal cultivators used that spiritual material to build their spirits, at most they expanded the three qi pools, but the use of spiritual pills would be even less.

Touch!

In Li Duzhi's hand, there was an extra flame, a familiar flame burning technique.

Only a few seconds later, the flames gathered, and Li Dui satisfied his head, using this kind of spell during the spirit building period, the rate will be much faster. Thinking about it, his strength is not much different, but now in the Spirit Gathering Array, he didn't dare to experiment at will.

Li Du was about to crush the flame in his hand and destroy it, but suddenly found that there was a faint wisp of purple in the red flame.

He approached the flames, and his spiritual sense felt, indeed, that wisp of purple, with the aura of purple hearts. The purple veins were mixed into the flames, making the flame burn hotter and hotter than before, and the essence was not dry.

Is this the attribute of using spiritual materials?

Li Du didn't dare to be sure. Using that spiritual material to build a spirit can indeed make an immortal cultivator get a special improvement, but with such a small probability of mercy, he can't feel that he can have such a way of luck.

It may be that the spiritual power of purple hearts has not been completely absorbed.

Li Du reined in the flames, used the cleaning technique, emptied the dirt and blood stains nearby, and sat cross-legged again.

Don't think about it for a short time, but he has more and more important things to do.

The Mythical Spirit Tower, which may release the ability of the fifth or sixth floor during the spirit building period, has long been waiting for this time. Now that it's finally here, his emotions are so intense that he can't control it.

As soon as he entered the spiritual sea, a familiar reminder rang, "Pay attention, the spirit tower is promoted, and the mythical spirit tower has the ability to put the fifth or sixth floor." "

The spirit tower in front of you is not only surrounded by yellow light, but there is an extra ring of aura on the outside, which is much more special and makes people feel more and more magical.

Li Du turned to the fifth floor.

"Improve?"

What is the significance? Li Du strangely stuffed a top-notch multicolored stone.

"This material has reached the top level, and there is no way to improve it. "

Li Du immediately understood, and jumped up a little.

Improvement is to improve the grade of materials, from inferior to medium, and from superior to top.

This, the strength is unimaginable. Li Du carefully investigated the surroundings of the Spirit Pagoda, thought for a while, and stuffed the best Moon Flower into the Spirit Pagoda.

He understands very well that in this world, there are very few top-notch ones, and they are completely subordinate to things that have no market to sell. Any thing with a level can reach the top, and the price is a surpass, so that it will be improved by a hundred times. Like this moon flower, the best can be sold for 10,000 medium spirit crystals, and the top things are also available for half a million of them.

Seeing the flower of the moon, he temporarily suppressed the joy in his heart, and he was going to be rich, completely rich.

"After observation, this material is third-class, and it has really been raised to the top?"

"Really!"

Silent for a moment, the spirit tower was not what he thought, it emitted light, and it was raised.

"The tower value is not enough, raise the third rank to the top level, only need the tower value of two hundred points. "

Two hundred points, a total of one hundred points, are you kidding me?

Li Du was also stunned and dumbfounded, and he didn't know where he had gone when he was happy before.

Very quickly, a reminder came again, "Turn on the ability to raise the tower value to the top." For every third-class or higher top-level material, the minimum tower value can be increased by 10 points, and the minimum tower value can be increased by 2 points for each high-grade spirit crystal.

But there are some expectations!

Li Du quieted down and planned seriously. Top-grade materials above the third grade, even if they are very poor, even if they are above 10,000 medium-grade spirit crystals. If you want to increase it to the value of two hundred points, you need a minimum of 100,000 medium spirit crystals, and the top materials are all hidden by the others, and they are very rarely sold, thinking about this, he is not very calm again, his head is higher, and it is not something he can do now.

It will be waiting.

Oh, there's a fine spirit crystal.

This may seem simple, but it is also very difficult to do.

The high-grade spirit crystal contains very rich and pure spiritual power, and there are few unmixed substances, and the cultivation of the immortal cultivators with the high-grade spirit crystal is very fast and very good compared to the third-class spirit gathering array, and they can also practice casually, without arbitrary restrictions. Because of this, very few high-grade spirit crystals are hard currency coins, and the market, even if there are 2,000 medium-grade spirit crystals, it is very difficult to exchange one high-grade spirit crystal.

Many materials are also priced with tens of thousands of hundreds of thousands of medium-grade spirit crystals, rather than high-grade ones, so it is basically impossible for immortal cultivators to use those high-grade spirit crystals to buy goods.

High-grade materials are originally high-grade materials.

If it is really a wasteless lunch in the world, the top materials are not so good, Li Du restrained his crazy mood and shook his head bitterly.

Taking out the moon flower, he didn't put in the material again, for this, the best material is not very difficult, it is difficult to obtain the top level, and there is no need to experiment again.

He put in a medium-sized Spirit Condensing Pill.

The light green pill is surrounded by a blue pattern.

"After inspection, this material is a third-grade medium pill, and it has really been raised to the highest grade?"

"Really!"

Blue mang, golden mang, mixed together, a pill popped out, and the blue lines on the top were obviously much deeper, and a few of them seeped into it.

"The third-grade medium pill is raised to the highest grade, and it costs a hundred point tower value. "

Very good, it can be done, Li Du nodded his head.

Li Duzhi is happy to return a lot again, and the pill can also be improved, so he can make a lot of changes, and his future plans can be implemented more and more.

I don't know, can I treasure it?
