Xu Mu gritted his teeth and waved his hand, after all the scrap iron was put into the storage bag by him, Xu Mu's eyes showed a strong strange light, and he went out of the cave again, and when he came back again, Xu Mu was already expressionless, this time, he bought more, and spent 5,600 spirit stones, so he returned to the cave and began to continue trying.

"Spirit Alchemist, I must become a Spirit Alchemist." Xu Mu was extremely eager in his heart at the moment, as if a spirit refiner had become his obsession, and if he didn't become a spirit refiner, he would never give up, because in Xu Mu's opinion, he had already spent too many spirit stones for this, and he must not let these spirit stones go to waste.

With gritting his teeth, Xu Mu fell into madness, and this time, Xu Mu directly swallowed a pill of Pei Yuan Dan.

Pei Yuan Dan, a medium-grade spirit pill, is used in cultivation to only have the seventh layer of the Qi refining period, which is extremely wasteful, this kind of elixir, only when the cultivation reaches the late stage, can it really absorb its spiritual power, so at this moment, Xu Mu chose to swallow this pill, obviously he couldn't take care of so much.

As Pei Yuan Dan swallowed, Xu Mu's eyes were red, and blood filled his eyes At the same time, Xu Mu gritted his teeth and directly began to refine his spirit again.

And this time, the time is the same, the same half a month, and in this half a month, Xu Mu failed countless times again, and all the low-level magic weapons were basically destroyed, especially Pei Yuan Dan, which consumed three grains, but the spirit refining still did not succeed.

This made Xu Mu suddenly realize that the so-called spirit refiner really couldn't simply waste some low-level magic weapons and spiritual materials to succeed.

"It's okay, I still have spirit stones, it's a big deal, do it again, this time, Pei Yuan Dan can't be used, it seems that Pei Yuan Dan has no effect on spirit refining."

Xu Mu did not give up, but went out again, and when he returned, Xu Mu's spirit stone reserves were already less than a thousand, and this time, Xu Mu was ready to gamble on this last time.

This time, he was going to use the Heaven Absorbing Technique and the power of the Black Ding to operate, in order to further understand the spirit refining, and this time, Xu Mu was not disappointed, although it was still unsuccessful, but Xu Mu gradually discovered the problem of spirit refining.

"Spiritual power, spirit refining seems to have extremely high requirements for the monk's own spiritual power, and the spiritual power transformed by the Heaven Absorbing Technique is relatively pure, which meets the requirements of spirit refining, but obviously, the Heaven Absorbing Technique is not perfect enough, only when it reaches perfection, the higher its purity, in that way, the success rate of spirit refining will also be higher."

Xu Mu's eyes flickered, with the operation of the Heaven Absorbing Technique, with the skill of spirit refining, Xu Mu seemed to have sensed the requirements of spirit refining, and when he needed the purest spiritual power to refine the spirit, Xu Mu seemed to have seized a glimmer of opportunity.

However, looking back, the art of alchemy is mainly blessed on magic weapons and pills, these magic weapons and pills are all things transformed by extremely pure spiritual power, and spirit refining is a blessing effect, if the spirit refiner's spiritual power is not pure, then it will cause some damage to magic weapons and pills, which is also understandable.

But Xu Mu knew that the purity of his spiritual power now really couldn't meet that requirement, and if he wanted to achieve that requirement, his cultivation level must be above the foundation before he had the opportunity to try again.

Although the purity of the spiritual cultivation power in the foundation building period is extremely high, it does not mean that you can become a generation of spirit refiners, otherwise all the monks above the foundation building period are spirit refiners.

However, if Xu Mu wants to reach the foundation building period, it is obviously not possible to form it in a short time, so Xu Mu only has the Heaven Absorbing Technique to go.

And the origin of the Heaven Absorbing Technique is the Taixu Dao, but there are seven articles of the Taixu Dao, and the Heaven Absorbing Technique is only the first one, according to the records in the Taixu Dao, only when all seven articles are fused, can the real Taixu Dao be opened, and so, and the last article of the Taixu Dao, its requirements can be called against the sky.

In terms of the current Xu Mu, that is something that is unimaginable.

"Isn't there a second way? The integration of the seven articles of the Taixu Dao, without a strong cultivation, it is impossible to do it at all, so I can only let the cultivation improve step by step, and when the seven articles are fused, can I become a spirit refiner again? ”

As soon as he thought of this, Xu Mu's expression showed unwillingness, the powerful cultivation is integrated into the seven chapters of the Taixu Dao, don't say that he doesn't have it, even if someone is willing to help, it will have to consume a lot of cultivation, so it takes cultivation to fulfill an outsider, such a deal, not to mention that others will not think so, even if it is put on Xu Mu himself, it is impossible.

"It seems that everything has to wait until after the foundation building period to consider the existence of the spirit refiner."

Xu Mu was not discouraged, but silently encouraged himself, now that the task is imminent, if he goes to the Spirit God Tower at this time, it will obviously be a little too late, because tomorrow is the time to go out.

Zhao Jingya's information appeared on his identity token as early as when he was refining spirits, and he only glanced at it at the time, but he didn't take it completely to heart, and only cared about learning spirit refining.

"Tomorrow, the imperial capital of Qin?" At this moment, when I looked carefully at the information left by Zhao Jingya in the identity token, Xu Mu's expression was puzzled.

He had long heard that the headquarters of the forces of the affiliated families of the Spirit God Sect were all in the Qin Capital, and the purpose of his trip was indeed in the Qin Capital.

There was no detailed record of what to accomplish in the task, but he was asked to go to the Qin capital to find a person, this person was the envoy of the Spirit God Sect in Qin Capital, and he was also one of the many elders, but he was outside all the year round, and rarely in the Spirit God Sect.

And their task is to obey the orders of this sect elder.

Xu Mu didn't think about it randomly, but calmed down, after this period of refining the spirit, not only did he not succeed, but he made himself tired, at this moment Xu Mu swallowed a medium-grade Qi and Blood Pill, the dantian rolled, and the Heaven Absorbing Technique ran violently, and then, the power of the cyclone frantically absorbed the spiritual power of the Qi and Blood Pill.

After a night of absorption and operation, Xu Mu finally completely refined the Qi and Blood Pill before the arrival of Zhao Jingya and the others.

The effect of the medium-grade Qi and Blood Pill is extremely strong, and the spiritual power transformed in it is even more like turning over the river and the sea, just by cultivating at this moment, it has been refined for a night before it is completely refined.

With the vibration of the identity token, Xu Mu knew that Zhao Jingya and the others had arrived.

As soon as he got out of the cave, Xu Mu found that outside his cave, the sky and the sun were covered, as if shrouded in haze.

"Yo, our first senior brother in the outer gate, did you just wake up?"

Xu Mu looked up, only to see that outside the cave, there was a huge floating object, this was actually a hundred-zhang law boat, it looked not only huge, but also a sense of coercion, and it spread out on the law boat.

And the one who shouted at him was the young man beside Wang Yiheng, his name was Chen Wen, like the Wang family, he was a child of a subsidiary family of the Spirit God Sect, standing in front of Wang Yiheng at the moment, shouting at Xu Mu.

"Senior Brother Xu, it's time for us to leave." Listening to a woman's voice, Xu Mu looked at Zhao Jingya's figure, standing proudly on the Dharma boat, like a god.

Xu Mu got on the French boat and saw a lot of acquaintances, including Long Ao, and even the young man surnamed Mo who tried to draw himself into Wang Yiheng's camp.

When he was in Linggu, Xu Mu had seen him, but at that time, his cultivation seemed to be only the fifth layer of the Qi refining period, and he had not yet reached the peak, but he didn't expect that this person had also successfully entered the inner gate, and Xu Mu was curious about this matter.

In this scene, Zhao Jingya seemed to have investigated and explained: "They are not wrong, I am the princess of Qin, my father, and the emperor of Qin, so it is not surprising that I have such a magic boat." ”

The original suspicion was now answered, and Xu Mu also suddenly realized that with the identity of Emperor Qin, as his daughter, it was very common to have such a magic ship.
