When Qin Yu left Zheng Lao's residence, he found that a few people followed, it seemed that there were still many people who were willing to do the business of killing people and seizing treasures, but he ignored these people, urging the speed of the flying sword to double, and quickly got rid of the pursuers.

After a day of flying, he found a secluded cave to meditate and rest, and when his mana was full, he hurriedly took out the leather and studied it carefully.

After half a month of sacrifice, he finally got his hands on it, and he also found that this thing is invulnerable, extremely tough, and his heart is worthy of being a fragment of a magic weapon, and ordinary magic weapons can't be damaged at all, the speed of this thing is indeed fast, but it's a pity that the loss of mana is also amazing, so it's not important, it's better not to use it.

"The mana urge will conjure up rain clouds, so it's called you...... Fly to the clouds!"

Two months later, he returned to the sect and immediately closed all inhibitions and began retreat.

After a year of heart refining road, he has a greater grasp of foundation building, you must know that the disciples at the peak of Qi cultivation, only one or two out of ten people have successfully advanced, and the Heaven and Earth Yuan Qi required when rushing through the level alone is an extremely huge number, almost the net worth of a disciple in the Qi cultivation period for decades.

Qin Yu is not too worried about this aspect of vitality, although he spent all the lower grade spirit stones to buy Feiyun, but he still has ten medium-grade spirit stones available, there should be no problem in terms of vitality, four second-grade pills and foundation building pills, at least seventy percent are sure that the foundation building will be successful, for qi cultivation disciples, this probability is already quite large.

But nothing is absolute, and luck is also very important.

He adjusts his physical state in order to achieve perfection, and when he builds the foundation, the slightest mistake can lead to failure, which must not be careless, and he sits there cross-legged for a full day, both physically and mentally close to perfection.

Ten medium-grade spirit stones were placed around, forming a small spirit gathering array, and he sat in the center of the spirit gathering array, closing his eyes and exercising, so that the mana could swim in his body and warm up.

Suddenly, with a finger of one hand, the Spirit Gathering Array opened, and more than a dozen medium-grade spirit stones lit up, and the spiritual energy erupted like a flood, forming a cyclone above his head.

At the same time, the Heaven and Earth Yuan Qi frantically poured into the cyclone here, further increasing its prestige, and the bottom of the cyclone was connected to the top of Qin Yu's head, infusing his body little by little.

This process was quite slow, Qin Yu felt that there was a hot spring flowing in his body at first, which was very refreshing, but gradually, this hot spring turned into a hot stream, and it was very painful where he passed, and he endured the pain and still ran the exercises over and over again.

This process is very dangerous, the slightest mistake will collapse the pool's vitality, and when the body is close to saturation, the huge vitality will impact towards the dantian.

Rumble!

The pain was so severe that he almost fainted, but the entrance didn't move!

He hurriedly gathered his mind, gathered his vitality again, and rushed through the level for the second time.

I don't know how long later, when he rushed through the gate for the thirty-sixth time, a crack suddenly appeared in the solid door!

Overjoyed, he hurriedly gathered his vitality and carried out the thirty-seventh rush.

At this moment, the huge vitality has been exhausted.

He was shocked, although he was already mentally prepared, but the difficulty of this bottleneck was still beyond his imagination, without saying a word, he found a second-grade pill and took it!

The terrifying mana almost burst his body, and he hurriedly guided these mana to continue rushing towards the entrance.

Thirty-eighth, thirty-ninth...... Forty-eight times!

Mana is exhausted again!

Take the second pill and continue to rush the level!

The third, the fourth!

With the assistance of the four pills, after countless rushes, the entrance has become very loose, but it is far from enough to break through! At this moment, the medicinal power of the last pill has decreased, and once the impact is stopped at this time, the previous efforts will be lost!

Gritting his teeth, Tsukidan took out the storage bag and swallowed it in one gulp.

After Tsukidan took it, he didn't feel anything special, and when he was in doubt, suddenly a violent force erupted from his abdomen, impacting in all directions, and the severe pain instantly filled the entire brain.

With a bang, there was no need to control it at all, and the terrifying mana rushed towards the entrance!

Boom! Boom!

If the mana that Qin Yu mobilized before was like the water of a river, then the mana that Zhuji Dan had transformed was a stormy wave!

After many impacts, the loose porch was crumbling, and he was still making the last struggle, Qin Yu had already felt that his brain was like thousands of thin needles pierced into it, and he almost screamed out in pain, until the power of the medicine subsided, and the pain was slightly relieved.

He collected his mind and looked inwardly at the Purple Mansion Dantian.

"It hasn't broken through yet!

This discovery stunned him, and finally he had to believe that the difficulty of building a foundation was far beyond his imagination, and he cursed secretly, and the last one of the Tsukidan was accepted!

The manic power reappeared, the pain rushed straight to his head, and with a buzz, his brain lost consciousness, and before he fell unconscious, he seemed to hear the sound of cracking silk.

Outside the glazed cave, the two low-level disciples they met half a year ago were collecting clear condensation dew here, and after seeing Qin Yu, the two knew that this was a senior brother's cultivation place, and they hadn't come for a long time, but after a long time, they couldn't see the figure of that senior brother, so they had the courage to come again.

Strange to say, there is more clear dew here than usual, and the collection of one day is even more than two days in other places, which makes the two of them very happy, so they get up early every day and come here at night.

The two of them didn't know that this was because there was a spirit gathering magic circle in the glazed cave, and the vitality of heaven and earth was gathered in this direction, and even some flowers and plants were affected by it, and they were extraordinarily luxuriant.

At this moment, the two of them suddenly felt that the vitality of heaven and earth had changed, as if it was even stronger.

"Senior brother, do you feel it?"

"Well, what a rich heaven and earth vitality!

The man followed his direction and looked up, and saw a large area of colored blue light in the sky at some point, like a water curtain hanging in the sky, at this moment the sky was clear, and the blue light was extremely conspicuous, I believe that not only the two of them, but also others must have seen it.

Such a vision of heaven and earth, the two of them were stunned for a moment.

The blue light fell from the sky and disappeared into the belly of the mountain.

This is a vision that should only be in the advanced foundation building period!

I don't know how long it took, Qin Yu woke up, as soon as he woke up, he hurriedly checked the Zifu Dantian, and found that the true qi had disappeared, turning into a gurgling stream, flowing quietly, seeing this, his eyes finally lit up, and ecstatic laughter spread throughout the entire cave.

"It's a success! It's really a success! Hahaha! Lin Daoyuan, wait, it won't be long before I will find you in person!"

The divine consciousness withdrew from the Purple Mansion, and was stunned to find that a large number of black impurities appeared on the surface of the body at some point, like mud, and it was a joy again.

"I didn't expect that my physique would change again after building the foundation, so it would be more convenient to cultivate!"

He walked out of the inner room, took off his clothes and plunged into the cold pool, the cold toads hurriedly jumped out of the water, looking at Qin Yu and shivering, the coercion exuded by Qin Yu had already made them feel threatened.

Qin Yu didn't care, he swam in the water like a swimming fish, and the cold cold pool water stimulated his skin and made it more comfortable.

Xiao Bai swam over and lay on top of his head, very happy, although Qin Yu had advanced to become a master of foundation building, it was not abnormal at all.

This also made Qin Yu feel cordial, no matter how he changed, Xiaobai always regarded him as the closest person, and this would never change.

After washing his body, Qin Yu removed all the prohibitions, pinched his fingers, this retreat actually took half a year, and when he thought about it, he was already a twenty-year-old young man.

A twenty-year-old foundation building master is also very rare among monks, not to mention that his spiritual root attribute is still the worst, in the eyes of others, this is simply a miracle.

After the foundation was built, it was really very different from before, and the true qi was completely liquefied and became the true element! This was not the result of quantitative changes, but qualitative changes! True elements and true qi were not the same at all.

"I didn't expect that with my physique after washing the marrow, I also used up two Zhuji Dan to build the foundation successfully! But speaking of which, the effect of Zhuji Dan is really strong! Thanks to Gu Yuan's ......"

After advancing to build a foundation, his identity also rose, and he became a veritable middle-level monk, a true disciple, and the backbone of the sect. He didn't rush out, but first familiarized himself with the changes brought to him by the foundation building period, the intermediate spells that were difficult to master before were easily mastered, and the low-level spells could be instantaneous, and there was no need to chant spells at all, even the small lightning strike technique with extremely great power came with an open hand.

"It's no wonder that ten monks at the peak of Qi cultivation can't compare to a foundation building monk, if you compare a foundation building monk to a fifteen or sixteen-year-old boy, then a Qi cultivation monk is a five or six-year-old child, even if there are more children, they can't beat a teenager, that's the reason. After so long in retreat, it's time to go out and breathe!"

As soon as the prohibition was opened, two breaths were immediately detected thirty zhang away.

"There's someone here! My divine sense can already make it impossible to hide within thirty feet. ”

As soon as they appeared, the two low-level disciples immediately bowed down: "Disciple to meet Uncle Shi, congratulations to Uncle Shi for his great success!"

Qin Yu smiled slightly, these two people are interesting, take a closer look, aren't these two low-level disciples who just advanced to the twelfth layer of qi cultivation a year ago?

Speaking of which, there are these two people by his side for the two advancements, and the two of them seem to be his lucky generals.

Seeing the two of them respectfully prostrate on the ground, Qin Yu only felt funny: "You guys are here to collect Qing Condensate again?"

"Yes!" the two disciples said respectfully, and when they saw Qin Yu, they knew that he was the senior brother who had a relationship.

"Oh, get up, I've seen you two two in the two advancements, and it's also fate with you, these two bottles of pills are of no use to me, so I'll give them to you!"

The two took the jade bottle and opened it to see that it was ten Aiki Pills, and they bowed down again with great joy. After getting up, he found that Qin Yu's figure was already missing in front of him.

The two had to bow to the glass cave and leave happily.

After the foundation is built, Xianxia Peak can not be used, and the monks in the foundation building period have the right to choose an independent mountain as the cave, and the spiritual power and resource rights of a mountain belong to the individual, which is particularly important.

Qin Yu first went to Xianxia Peak to say hello, and the deacon disciple Xu Shi had a relationship with him several times, and was immediately surprised when he saw him.

"You, you...... Become a foundation monk!?"

Xu Shi didn't believe his eyes at all, but the facts were in front of him, that spiritual power coercion was definitely not something that a Qi cultivation stage disciple could have, Qin Yu had only been a disciple of the Inner Sect for a few years, and he had actually become a foundation building master in such a short period of time.

Qin Yu was amused when he saw his expression, and he was a little proud, coughed lightly, and pretended to be majestic: "Yes, Qin came this time, firstly, to pack his luggage, and secondly, to receive his identity token." ”

He already knew that this Xu Shi was the younger brother of Xu Yan in Xuanshu Pavilion, and the two brothers helped him a lot, they were not outsiders, and they teased him a little.

Xu Shi finally believed that what was in front of him was true, and hurriedly bowed down and said, "Don't dare, I will personally take care of Uncle Shi's things, but if you want to receive an identity token...... I'm afraid Uncle Shi will be disappointed, the younger generation can't make the identity token of the foundation building period monk here. ”

"Oh, it's Qin who is abrupt, where do I need to get it?"

"Immortal Xuan Main Peak!"
