Every second seemed to be as long as a century had passed, and Lu Yu had never thought that time would be so difficult, even in the flow rate of time and space of one to hundred, he had never felt like this.

After hundreds of lower-grade spirit stones were absorbed by Lu Yu, Lu Yu felt like the aura qi mass in the broken car without oil had some movement than before, and there were signs of rotation, but no matter how you look at this rotation, it looks like an old man is walking tremblingly, and the lamp will run out of oil at any time.

"Still not enough?"

Lu Yu didn't want to guess why, first all the heavenly and earthly treasures, and then all the low-grade spirit stones, he didn't seem to have much left now.

Lu Yu's eyes fell on the low-level magic weapons in the storage space, and he thought that he could leave something, but now it seems that it would be good to be able to save his life, these are all things outside the body, anyway, they are also used on their own bodies, and they are not wasted on others.

After getting the system from Lu Yu, he knew that this was a road with no advance or retreat, and cutting off the path of cultivation was equivalent to being abandoned by the system, even if he was not abandoned, he was a wasted person, like a boat that sank at any time in a sea storm, did he have to live in fear all day long?

"No!"

If you don't succeed, then die!

Lu Yu was so ruthless that he was even afraid of himself, remembering that when he fell in love for the first time in college, after his first love was maintained by a foreigner, he secretly followed him for a week, and when he found out that they were opening a room, he made a phone call to the police * inspector, and saw that the two dog men and women were brought into the bureau before he let out a bad breath.

Isn't it a half-price recycler? I've eaten this loss!

A piece of low-level magic weapons was sold to the system by Lu Yu at a low price, in exchange for one or two hundred skill points, plus the remaining skill points in his hand, Lu Yu had more than three hundred skill points in his hand, and was immediately exchanged by Lu Yu for countless heavenly and earthly treasures, and finally swallowed by Lu Yu into his stomach.

These are all skill points in exchange for heavenly and earthly treasures, which are much stronger than the previous low-level heavenly materials and earthly treasures, although the number is not much, but the medicinal effect is stronger I don't know how many times, but unfortunately now Lu Yu doesn't care about what the medicinal effect is, if there is time, exchange these heavenly materials and earthly treasures for spirit stones and reabsorb, the effect will definitely be much stronger than now.

But Lu Yu doesn't have time at all now!

Although this is extremely wasteful, Lu Yu only has this path to choose, and it is also a path that he doesn't know if he can succeed.

My life is gone, and I care about other things, so my brain is really broken!

"Still doesn't work?"

As the skill points decrease little by little, in fact, the effect is still a little bit, and the aura qi mass in the dantian has already rotated, but the speed is so slow that it makes people feel sore, no matter how you look at it, it looks like it is about to stop.

Lu Yu knew that at least his current path was feasible.

Although the skill points are a little bit fleshy, it also makes Lu Yu see hope, but the more than three hundred skill points will soon bottom out, and the speed of the dantian aura qi mass is also much faster than before, and it feels like he can succeed with a little more effort.

But Lu Yu no longer has any skill points, and there are still some things left in the storage space, such as the Five Elements Pill, Dragon Bird Knife, Mixed Yuan Dan Furnace, ......, do these things have to be sold?

To be honest, Lu Yu has collected a lot of treasures during this time, but there are some things that he is really reluctant to sell, such as the armor that he wears with green beads and gives to himself, and the recycling price is also 25 skill points, do you want to sell it too? Another example is the soul ring that Ziyan gave him, which is also worth 15 skill points, should he sell it?

"Let's sell the Five Elements Spirit Pill that you can't use first!"

Lu Yu's Water Spirit Root, Wood Spirit Root, and Earth Spirit Root had been raised to the limit, and there were still some such elixirs left in the storage space, which were originally intended to be left for use in case of emergency, but now it seems that there is no need.

Dozens of Five Elements Pills were sold by Lu Yu in exchange for hundreds of skill points.

Lu Yu no longer knows how many skill points he has spent, is it important to have his own life?

In the past, Lu Yu was eager to break every skill point in half to use it, but now it is like flowing water with skill points, and everything is really unpredictable!

As the middle-level heavenly and earth treasures entered Lu Yu's body, Lu Yu's face finally began to be happy, and the aura qi mass in the dantian finally showed signs of acceleration, as if there was a huge force pushing forward, faster and faster, and a state like a spiral nebula.

As the aura air mass rotated, the aura aura was also changing in the middle, as if a huge traction force appeared in the center, firmly confined the surrounding aura around the cyclone, and made it rotate wildly around the center of the cyclone.

At this moment, a thunderbolt seemed to flash in Lu Yu's mind, illuminating Lu Yu's entire body, and every cell in his body seemed to have received some unknown order and began to actively absorb the surrounding aura.

"Boom!"

Lu Yu's body shook, and the surrounding aura also vibrate, and countless aura cyclones also appeared around, and began to swallow the surrounding aura.

"It worked!"

At this moment, Lu Yu could clearly feel that a large amount of aura was rioting around, forming tiny aura cyclones, pouring the surrounding aura into Lu Yu's body. The aura cyclone in the dantian was also frantically absorbing the surrounding aura as it frantically absorbed the aura around it, and the aura cyclone became larger and thicker and thicker, and at the same time began to compress inward.

Lu Yu felt that his abdomen was slightly hot, this feeling was a bit dizzy like being drunk, and every pore on his body was refreshing, which made people want to scream.

The seventh-layer dantian of Qi refining condenses the aura cyclone, which can confidently absorb the aura of the outside world all the time like the Chaos Demon Skill, even if the monk does not usually cultivate, his cultivation will grow slowly, which is one of the benefits that the seventh-layer transformation of Qi refining brings to the monk.

At the beginning, only the muscles and bones can be observed, and after the cultivation is improved, this internal vision ability will also improve, and in the later stage, they can even see the nucleus ...... every cell in their body.

Of course, the benefits of the seventh layer of qi refining do not stop there, with the emergence of the spiritual qi cyclone in the monk's body, the monk needs to take less and less food from the outside world, in the early stage, even if the monk does not eat or drink for six or seven days, he will not have the slightest sense of hunger, which is also one of the reasons why the senior monk is becoming more and more picky about the ingredients, because they don't look at ordinary food at all.

From this point of view, after the seventh layer of qi refining, the monk is no longer an ordinary person, which is why it is said that after the seventh layer of qi refining, he can be regarded as a real monk.

When refining qi at the seventh layer, the monk's physical fitness will improve by leaps and bounds, such as being able to read the small print on the newspaper clearly within a hundred meters, such as having a certain night vision ability, such as hearing is more sensitive, etc., the monk after the seventh layer of qi refining is really not like ordinary people.
