Ling Xian himself is a master of the Dan Dao, after taking a large amount of solid Pei Yuan's pills, his injuries suddenly improved by seven or eight points, and in the following days, he deliberately improved the pill recipe for washing the marrow, and added two new medicinal materials, after Qin Yu took it, he entered the Dan furnace again, and carried out a maddening process of washing the marrow with the extremely cold power of the cold water.

This process was very long, until half a year later, his body had no impurities discharged, and at this moment, he actually fell to the level of Qi training.

Ling Xian has been improved many times, and the effect of the Pulp Cleansing Pill has become more and more significant, at this rate, maybe the Pulp Cleansing Pill that can wash the marrow in ancient times can really appear in his hands again, this is a big event that is beneficial to the entire Longxi, how can he not be happy.

After a year of extreme cold and extreme heat, Qin Yu's spirit was also extremely sluggish, if it weren't for the Ten Thousand Tribulation Vajra Body, he would have been unable to bear it a long time ago.

At the time of separation, Ling Xian also deliberately took out a few bottles of Aiki Pill and gave them to Qin Yu to help him recover his mana, but he didn't care about these, what he wanted was the precious waste pill that Ling Xian had collected.

"What do you want to do with the Waste Pill?" asked Ling Xianhu suspiciously.

"This, the kid is quite yearning for the art of alchemy, so he wants to ask for some pill research. ”

Hearing this, Ling Xian's pupils shrank slightly, and he thought for a moment and said, "I have some here, you can take them first!"

He casually took out a small wooden box and opened it, and there were more than thirty strange-shaped pills lying quietly inside.

"Is that all?" Qin Yu was very disappointed, you must know that Uncle Lu Yun had thousands of Waste Pills at the beginning, and Ling Xian, as the head of the Dan Hall, was far from being comparable to Lu Yun.

"Of course not, but the old man, as the head of the Dan Hall, is responsible for everything he does, and the waste pill is no different from poison, who knows if you will use it to harm others, so it depends on you to help me try the pill, otherwise I won't give a single pill!"

Seeing that what he said was extremely solemn, Qin Yu gritted his teeth and said, "Don't hide it from the elder, the kid needs a large amount of waste pills, if the elder can provide it, the kid is willing to exchange it for toad liquid, how about it?"

"How do you want to change it?"

"Well...... One hundred second-grade waste pills, exchanged for five taels of cold toad liquid! What do you think?"

"Deal!"

Ling Xian agreed without any hesitation, Qin Yu opened his mouth, and saw a sly smile flashing in the depths of his eyes, and shouted that he was fooled.

"You take this box of waste pills first, it's enough to exchange for a year's toad liquid!"

Elder Ling waved his hand, and a huge wooden box appeared in front of him, more than two feet high, and Qin Yu's whole person was stunned.

"These ...... All of them?"

"Well, this is all accumulated by me over countless years, I'm afraid there are more than 3,000 pieces, but they are all some first-grade and second-grade garbage pills, and fortunately, you only need second-grade waste pills, you must know that the real best waste pills are also very useful, you go back first, don't look forward to sending the toad liquid!"

"Yes!"

Even if he was fooled, Qin Yu was like a treasure, and picked up the heavy wooden box and threw it into the storage bag.

"Thank you, Elder, the junior will say goodbye, by the way, the junior will go back this time, and he will go back to retreat to recover his mana, I'm afraid it will take a long time, and I hope the elder and Uncle Liu will say hello there......"

"Yes, you can go. ”

After bidding farewell to Elder Ling, Qin Yu hurried back to the Liuli Cave in a hurry, and the first thing he did was to retreat and cultivate to make up for the loss of cultivation. If nothing else, let's just say that the current realm is too low, and it is extremely difficult to release even the simplest fireball technique. This point of cultivation is not enough to even protect oneself.

The toad liquid that had been accumulated for a year was all taken out at this moment, and a drop of it was taken cross-kneeled and entered into meditation.

It's a year in a flash.

On this day, two low-level disciples who collected Qing Condensation Dew came to the vicinity of the Liuli Cave, both of them were cultivators of the fifth level of Qi training, and they could only collect a little bit when they got up early in the morning, and the Liuli Cave was sparsely populated, and it was much more convenient to collect the Qing Condensation Dew, and the two of them had been here for many days.

At this moment, there was a trace of surging Heaven and Earth Yuan Qi, gathering in one direction, and more and more, the two disciples immediately discovered this vision, and gathered together in a panic, not knowing what was happening,

The two of them looked fixedly, and the place where the vitality gathered turned out to be the cave mansion with a ban.

"Look at this posture, there is that senior brother who is cultivating. ”

This vision did not last long, and the Heaven and Earth Yuan Qi soon regained its calm, and at this moment, the Liuli Cave Prohibition was opened, and a person came out of it.

The strong coercion emanated from that person's body, which actually made the two disciples have a sense of worship, Qin Yu was also stunned when he saw that there were people outside the cave, but when he saw the cold sweat of the two of them, he showed a trace of suddenness, and as soon as the coercion on the body surface was collected, the pressure on the two of them suddenly dissipated invisibly.

Needless to say, the two of them also knew that they had met a master, and hurriedly stepped forward to salute: "Meet Senior Brother!"

"Well, why are you two here?"

"Back to Senior Brother, we are here to collect Qing Condensate Dew, just because there are few people here, and the dew collected is two or three percent more than other places, not intentionally disturbing Senior Brother Qing Xiu. ”

Seeing that they were each holding a small bottle in their hands, Qin Yu nodded and said, "I see, you guys go on." ”

"Yes, thank you, brother!"

Qin Yujia took off his sword and flew away, and the two of them breathed a long sigh of relief.

"This kind of coercion, even in the eleventh layer of the Gu Senior Brother, I have never seen it, could it be that this senior brother is a top master of the twelfth layer of Qi training?"

"I'm afraid so! Fortunately, this senior brother didn't embarrass us, let's quickly collect the condensate and leave." ”

"Okay, don't annoy people with this disappearance. ”

The two of them guessed well, Qin Yu was really already a storage of the twelfth layer of Qi cultivation.

In the past year of retreat, Qin Yu's speed of absorbing spiritual energy has increased by as much as three times, which is all due to the effect of cleansing the marrow, which has also led to a great increase in his cultivation speed, and it only took nine months to recover his original level. Qin Yu continued to cultivate, and with the remaining toad liquid, it took another three months for mana to be saturated, and then he began to attack the bottleneck of the twelfth layer of qi training.

The marrow washing was successful, coupled with the accumulation of more than a year, he naturally estimated it in his heart, but even so, he still did not succeed, and finally took three second-grade pills to achieve his current cultivation, and after coming out of the Huntian Valley, he exchanged for a total of seven second-grade pills, and now there are only four left.

After that, it was what the two disciples saw, Qin Yu had just successfully broken through the level, and his control of mana was still lacking, and the release of spiritual power scared the two of them.

The twelve layers of Qi cultivation are really very different from before, and the True Qi actually shows signs of liquefaction, which is the conversion of True Qi to True Yuan, once it is completely liquefied, it is the real True Yuan.

The power of true yuan and true qi is not the same, the cultivation of qi cultivation period, but the increase in the concentration of true qi, in general, is just a quantitative change, but the transformation of true yuan, is a real qualitative change! That is a new height, that is, to build a foundation!

With the Zhuji Dan, half of the chance of success is added, that is, a person who has been in the twelfth layer of Qi cultivation for many years, is extremely well prepared, and the probability of success in foundation building is only two or three percent, which shows that a Zhuji Dan is precious to the disciples in the Qi training period.

Of course, Qin Yu would not try to build a foundation now, he also needed to consolidate his cultivation, and the other thing was to make some preparations before building a foundation.

Spirit stones, he has a full ten medium-grade spirit stones, and there are hundreds of lower-grade spirit stones, the heaven and earth vitality is completely sufficient, the pill, and four second-grade pills and a large number of aiki pills, plus the increase of two Zhuji Pills, if this cannot be successful, then his path of cultivation will end here.

At this time, of course, he didn't dare to try rashly, his state of mind had not yet reached the state of perfection, and after so many years, it was time to go home and take a look.

He first went to Elder Ling to deliver the year's cold toad liquid, and said hello to the deacon disciples of Xianxia Peak, and then took off the sword and flew away.

This trip is not simply going home, before ordinary people are ready to build a foundation, they have to travel the world for a period of time, it is to refine the heart, when building the foundation, a small mistake may lead to the failure of building the foundation, the state of mind is particularly important, after practicing in Xianxuanmen for several years, it is time to appreciate the customs and customs of all parts of Daqin.

He bought a large number of Qianli talismans, sticking them on his legs and rushing out like the wind, Qianli Fus traveled thousands of miles a day, and three days later, when Yangling was in front of him, as soon as he stepped into this land, his heart was much sadter.

Qin Yu slowed down and walked through the familiar road step by step until he came to Qin Hu Village.

The mountain road was overgrown with grass, covering the road, Qin Yu walked and cleared the weeds with his sword, and when he walked to the entrance of the village, it was already night.

At the entrance of the village, several huge horse-resisting piles were erected, and there was a stone tablet next to it, which read: "Forbidden land! Forbidden to break into - Long Wuwei." Great Qin was established in 714. ”

Qin Yu was stunned for a moment and muttered, "Flying Tiger...... Is that you?"

He walked to the village in a daze, with a broken arm and overgrown with weeds, and from time to time a hare would emerge from the weeds.

Qin Yu walked to the southern slope where his relatives were buried, and kowtowed respectfully.

"Dad, mother, the second baby has come to see you!"

Put some food and old wine, then take out the bamboo flute and play it gently, after cultivating immortals for many years, I have my own perception of life, and the flute sound reveals a trace of smart and ethereal dust.

He lay on the ground, looking at the stars in the sky, as if the eyes of his parents were looking at him, blinking and blinking. Meimei smiled and fell asleep peacefully.

Early the next morning, he came to the secret stone cave, Qin Feihu really came back, and left a few words for Qin Yu, this guy had already made a name for himself in Long Wuwei, and became the youngest commander in Long Wuwei's history, Qin Yu left a few pills to strengthen his body and prolong his life, and left some words, and then left.

He mapped out a route for himself, passing through Xiling Prefecture, Yunzhou, and Anzhou, all of which were all spheres of influence of the Immortal Xuanmen, and he was not worried about any danger.
