"Wouldn't it, in just such a short period of time, the fire crystal token will become powder?" Yu Pu watched as the fire crystal powder in his hand kept leaking out of his fingers.

"Silly boy, what are you upset about, why don't you hurry up and put that fire crystal powder into the Dan bottle, this fire crystal powder is very useful, especially the alchemy and your heraldic engraving, hehe, oh, by the way, and, you just absorbed the fire crystal energy, you have to hurry up and let the fire cultivate together, don't waste it, I won't speak, the cultivation is gone, hehe......"

Yu Pu didn't dare to ask, Lao Dan cultivated by himself, and he had to hurry up, he looked at his companions, and found that they were eating barbecue while watching him, and waved his hand at them, closed his eyes again, and began to cultivate the spiritual vein.

The so-called fire crystal energy, that is to say, has a certain effect on the fire veins and fire spirits, including the expansion of the meridians, the promotion of the fire spirits, etc., if you suck alone, it has little effect on other spiritual veins, unless it is five crystals and five veins.

Whoo, the fire spirit followed Yu Pu's inhaled fire crystal energy, like a leap, a little red light flashed, flying around Yu Pu's body sitting on the ground, like a burning firefly, sometimes fast and sometimes slow, Yu Pu couldn't see it because he closed his eyes, but Lan Ming Yu Yue and others could see it clearly, and the four of them sat around Yu Pu together, looking at this strange phenomenon.

In the past, when the fire spirit vein was cultivated or expanded, it was all a ploughing expansion shovel by shovel, but at the moment, this kind of fire crystal energy is a kind of spiral expansion meridians, like a strong diamond drill bit, which has been drilling and twisting inside, painful, and bursting for a while, making Yu Pu sweat uncontrollably, his sword eyebrows are locked, and he trembles all over, but he just didn't make a sound, because he knew that his sister was not far away.

But the four of them were already on the side, they looked at Yu Pu, not long after, the small dot that was bubbling with flames was gone, and Yu Pu's eyebrows were locked all of a sudden, his whole body trembled, sweat was like water, everyone panicked for a while, Yu Yue couldn't help but shout softly, "Brother, how do you pull" When he couldn't help but stretch out his hand, he was stopped by Yu Yue: "Little senior sister, your brother is expanding the meridians, don't disturb him......"

"Senior sister, how do you know?"

"I, oh, what Hidetake told me......"

"Brother, my brother looks too painful, this won't, won't ......"

Yu Yue shook her head lightly and said: "Well, no, your brother's method is an extremely difficult to cultivate 'hard chisel' method, accept the hard chisel with his own strong endurance, but the harvest is also very great, little junior sister, mainly rely on himself to survive, outsiders are not easy to help"

"I have always thought that Yu Pu's achievements are rapidly in three aspects, one is the external auxiliary, heraldry, elixir, one is diligent practice, morning classes, evening practice is uninterrupted, the third is talent, like to ponder, research, now it seems to be ......" Lan Ming looked at Yu Pu who was sitting there upright, the tenacity was too exposed, and he couldn't help but sigh lightly, and then said: "He also has one quality, that is, hard-working, pain-tolerant, forgetful, and admire......"

"This is the boss, my boss ......" Lu He was convinced, his eyes full of little stars.

Yu Pu finally incorporated all the fire crystal energy into the spiritual vein, at this time, the fire spiritual vein has expanded by almost half of the meridian channels compared to the past, and he has gained a lot, he glanced at it, and suddenly saw four pairs of eyes looking at him, he couldn't help but be surprised, and then looked at himself, except for his clothes were soaked, there was nothing else abnormal, so he asked strangely: "How do you pull?"

"Are you alright?"

"Brother, you're fine."

"It's okay......" Yu Pu nodded to everyone, then picked up the wordless bow on the long stone, and said to Lan Ming: "Lan Ming, this bow is suitable for you, you keep it, and I will engrave it for you later......"

Lan Ming took the bow, pulled the string, and said with satisfaction: "Well, yes, the pull is much better than the one you gave me before......" As he spoke, he put the wordless bow under the feldspar bar, and took out the original green bow, ready to return it to Yu Pu, but heard Yu Pu say: "You keep it first, as a backup ......"

Lan Ming had no choice but to take it, he didn't like the feeling of seeing outside, Yu Pu took out a few more Dan tubes, all of which were ten Dan loads, and then took out Bigu, three Hui Dan, one for each person, and sent it down, and then there were arrows, so many rings, they hadn't been sorted out yet, so they would talk about it when they were sorted out, so he said: "Okay, now let's go and rest, I still have to engrave this wordless bow here, and there are still some things to ......."

The four of them dispersed, and each of them went to build a tent.

Yu Pu didn't look at the ring carefully, when there were more than 700 burst arrows in the third, fourth, fifth, and sixth rings, and more than 500 flame bolts and more than 500 blast arrows appeared, he didn't want to look at it below, so he took out the burst arrows, divided them into five piles, 300 each, made a bundle, and collected a bundle himself, and then a hundred wind arrows and flame arrows per person, divided into four or two piles, and placed on the side of the burst arrow, and now pull it down to take into account the wordless bow.

The attributes of the blue body are wood, and the bow should also be based on the wood coat of arms, divided into two coats of arms, wood and wind with the same attributes, then you can consider the storm coat of arms or the coat of arms of the forest, supplemented by the water system, then you can consider the coat of arms of Miao and the coat of arms of the 㵘, the main speed of the storm, the coat of arms of the forest is the main help, the main mind, well, just set the storm, the storm is one level higher than the coat of arms of the forest, the cultivation of the blue is absolutely controllable, and the coat of arms of the water system is matched by the coat of arms.

After deciding on the coat of arms to be engraved, Yu Pu began to take out the storm essence and the 㵘 coat of arms essence and began to engrave them.

Bite......

The storm coat of arms on the grip has been engraved in less than two moments, and this time the engraving is more than the previous one, not only to take a study that I have a lot, but also to be smooth, inexplicably smooth, and then the next is the lower grip, that is the coat of arms of 㵘, and it is less than two moments of time, and it is a ding...... Haha, it worked.

"This bow, let's call it a storm......" Yu Pu put the bow aside, now, he wants to alchemy, just now Lao Dan said, absorbing the energy of the fire crystal, not only is it good for alchemy, but it is also helpful for the engraved coat of arms, the engraved coat of arms has been tried, how about alchemy now?

Alchemy, so what kind of Dan do you want to refine?

Bigu, the three major Hui Dan are now very sufficient, hey, by the way, let's refine the Breath-Holding Pill or the Hidden Pill, this Pill is used a lot these days.

Take out the Qizheng Dan furnace, take out the medicinal materials that hold your breath, and the mental power becomes mud, this mental power urges, and the mud becomes quickly, and the refining of the medicinal materials is completely fire to mud, although this is said to be a little bit of the merit of the fire, but Yu Pu obviously feels that the current mental power is a little different from the previous one, and the current mental power is definitely improved to a level in terms of speed and impact strength, it seems that the absorption of fire crystal energy is also extremely helpful to mental power.

Fire crystal is like this, and aquamarine is definitely like this, the difference is that the aquamarine field is absorbed in the field, and the fire crystal is absorbed by shaking hands, what Yu Pu doesn't understand is the blue crystal absorption effect of Yuanfu, but it is not as good as the absorption effect of this piece of fire crystal. He didn't understand this, but Rao was like this, the aquamarine field was also a source of energy waves that allowed people to absorb extraordinary, no wonder the aquamarine field in the Yuan Mansion was red by so many people, well, this time I have to pay more attention to the Five Elements Crystal, and I don't know where the "mountain" of this fire python gang is, it's not good, he also has a fire crystal there, Yu Pu said to himself secretly.

Sixty-three Dan held his breath, and entered the Seven Political Dan Furnace, Yu Pu's five elements spiritual vein opened, and the fire seemed to be beaten with chicken blood, unusually active, completely driving the wood spirit and earth spirit, Hulalahe, very much like a child who worked hard to please, working desperately.

Half an hour has just arrived, the fragrance of Dan is overflowing, and Yu Pu can't believe his eyes, to be honest, this is not just a matter of time advance, now he is refining a furnace of Dan, and he has barely used much soul power, and Ran Dan has become.

"Danwu quality, all Danwu quality, hey, no, this is a lot thicker than the previous Danwu, is it ...... No, it's not Danyun yet, hey......"

Yu Pu took out the Breath-Holding Pill, and found that the Dan product was much higher, and there was a tendency to be close to the quality of Danyun, so he was very happy, and took out the Ten Dan Tubes, which were filled with Ten Dan in the four cylinders, and then put them in the four piles that were separated not long ago.

Now his soul power and true energy are almost full, and then he will engrave three bursting fury firebombs, as well as four sets of battle uniforms, etc., the combat boots are not needed now, and when these are all done, Yu Pu stretched his body, looked at the time pendulum, and found that he was ugly, so he sat down again, his thoughts began to fly, because of the influence of fire crystals, the first thing he thought of was the cultivation of marrow-cutting, he took out the book ring in the "From the hammer body to the marrow-cutting", and turned to the page of marrow-cutting.

The "method of vein wrapping" for "solid bones", the method of wrapping veins of solid bones, Yu Pu has been taking the time to practice, and it is estimated that it is nearing the end today, because the last few times the needle pounding feels very light, very light, so faint that it is like the feeling of touching each acupoint, and it is the second stage of marrow cutting.

The second stage is called "cutting the marrow" to complete the bone, which is equivalent to the solidity of the container, then it is to the tempering of the marrow inside, and there are two cultivation methods for cutting the marrow, one is the "medicine spirit food marrow" is by eating Zhibao Ling grass or taking it directly, or refining into pills, through the energy efficiency of these medicine spirits, to achieve a kind of medicine spirit marrow, the effect is obvious, and the access is fast, the disadvantage is that the cost is very high, the elixir is difficult to find, and it is an unavoidable method.

The second is the "energy marrow" This kind of energy can be absorbed through the bone marrow cavity, into the bone, for fusion of the original marrow, and then mixing, marrow transformation and a series of marrow cutting effects, this method is more difficult than the previous one, because its requirements are first of all the opening of the spiritual vein, and the energy source is also quite difficult to find, for example, the spare, the single attribute is a little better, like Yu Pu's chaotic body, the five elements are all complete, the difficulty is not generally high, but this kind of cultivation method has a great advantage, that is, once it is absorbed into the energy po, then the effect of cutting the marrow is the best of all methods。

The two methods, none of them are simple, Yu Pu thought about it, the first method, it's not impossible, but there is no elixir at the moment, and it can't be implemented, so there is only the second way, now that the five elements of the spiritual vein have been refined, and the fire crystal has also been absorbed, as long as the fire crystal energy can be refined in the meridians, and then the bone marrow can be improved, that is the true meaning of marrow cutting, even if it is partial.

Just do it, Yu Pu looked at the cultivation method described in the book, according to his requirements for environmental aura, he was afraid that the aura in the current location was not enough, this time, he took out the spirit gathering array and the pregnant spirit cocoon, sat in the cocoon, and began to cultivate.

The Gathering Spirit Array and the Pregnant Spirit Cocoon emitted a psychedelic halo, and not long after, the Xiaobanshan cave where Yu Pu was located made a whining soft sound, and suddenly, the light mist at the entrance of each cave was faintly rising, and they all floated here, and it didn't take long for Yu Pu to be outside the cave entrance A burst of fine smoke and light cage accumulated, and then drilled into the cave one by one, gathering on the Spirit Gathering Array, forming an irregular spirit tent.

Time passed little by little, and suddenly ......
