In the last three months of the Heavenly Valley, Qin Yu did not slack off, the spirit body in his body was completely saturated, plus he was full of energy at the moment, he made up his mind and started to rush the level!

After sealing all the prohibitions in the glazed cave, he sat cross-legged in the inner chamber and immediately entered a state of retreat.

But what he didn't expect was that this time it took much longer than before.

On the day of the beginning of the month, Elder Ling Xian appeared at the entrance of the glazed cave on time, and seeing that no one came out to greet him, he snorted angrily and wanted to break the prohibition here, this kind of thing he had not done less before. As soon as he raised his hand, he slowed down, as if he had found that the vitality of this place was a little different.

"The vitality is so manic, it seems that someone is breaking through the bottleneck, just look at this posture, it doesn't seem good!"

Ling Xian suddenly took a step forward, and the whole person disappeared in an instant, and when he reappeared, he was already in the glass cave, and the prohibition at the entrance of the cave was not broken at all.

He smiled slightly, and when he came to the inner room, he saw Qin Yu sitting cross-legged, with a large number of abandoned spirit stones scattered around him, and the Heaven and Earth Yuan Qi was hovering above his head, but it was difficult to fall.

"Sure enough, it's this kid!

With that, with a big hand, the Heaven and Earth Yuan Qi suddenly condensed into a huge cyclone, which melted into Qin Yu's body along the top of his head.

Qin Yu in retreat was struggling to support him, and when he felt that it was difficult to control, the Heaven and Earth Yuan Qi suddenly poured into his body with the momentum of Daigo empowerment, and his heart was shocked, and he frantically absorbed the Yuan Qi and turned it into his own spiritual power.

After half a pillar of incense, I only felt that the body was light, the shackles of the shackles were broken, and an indescribable comfort spread all over the body, with the body as the center, the spiritual power fluctuations spread to the surroundings, and the eleventh layer of qi cultivation was finally completed.

He breathed a long sigh of relief, and he was still wondering in his heart, how could he have succeeded so wonderfully when he was about to fail before?

When I opened my eyes, there was an extra person in front of me, and I jumped back almost subconsciously, and at the same time, I slapped the storage bag, and the flying shield was clasped in my hand.

"The reaction is not slow!"

Ling Xian's eyes were full of banter, and there was a playful smile on the corner of his mouth.

"Elder Ling, why are you here?"

Qin Yu breathed a sigh of relief after seeing the appearance of the person who came, and when he thought back to the previous abnormality, he must have received the help of the other party.

"Of course I'm here to collect the toad liquid. ”

Only then did Qin Yu know that he had been in retreat for nearly twenty days unknowingly.

"The kid thanked the elders, the great kindness is not thankful, in the future, if you go to the kid's place, just open your mouth, the kid will go to the soup and die rather than die!"

"The scene is beautiful, you just need to deliver enough toad liquid in the future, by the way, don't you have a way to get more toad liquid? Sell it to me, the toad liquid has not been enough recently. ”

"Okay, I'm worried that there is no place to sell the excess toad. ”

This time, Qin Yu took out a total of five taels of toad liquid, exchanged for three medium-grade spirit stones, happily delivered the toad liquid, and put the spirit stones into the storage bag.

"By the way, I heard that you just came out of the Heavenly Valley, do you still have extra elixir in your hand? ”

"No, I got a total of seven elixirs, all of which have been contributed to the sect!"

Qin Yu's heart tightened, and he hurriedly shook his head, Ling Xian actually asked casually, and he didn't pursue it too much.

"Well, forget it. ”

After receiving the toad liquid, Ling Xian didn't stay too long, and as soon as he raised his foot, the whole person appeared outside the glazed cave, and the prohibition in the cave was still unharmed, which made Qin Yu feel a burst of admiration in his heart.

Seeing Elder Ling away, he took a few deep breaths, for some reason, he always felt a sense of oppression when he was with the Elder of the Yudan Period, maybe this was caused by the gap in the realm.

Soon, he meditated excitedly and began to observe the changes brought about by the eleventh layer of Qi training.

After practicing the eleventh layer of qi, the extremely proficient spells such as the fireball technique can be activated instantly without chanting a spell at all, and he also found that those spells that were difficult to learn in the past have also become much easier, and the mana has more than doubled again!

"If I continue to develop at this rate, by the time I reach the twelfth layer, my mana will be at least twice as much as that of a monk of the same level!

Thinking about his bright future, his heart was excited.

But soon, he thought of a new problem, that is, the bottleneck, the eleventh layer of Qi cultivation is so difficult, it is obvious that the further it goes, the more difficult it becomes, the next breakthrough, without the elders of the Dan period pressing the formation on the side, whether it is successful or not is still two words.

What's more, after going through Hun Tian Gu and his party, he knew the cruelty of the cultivation realm, and more than a hundred disciples of the Immortal Xuanmen died so inexplicably, so if he wanted to live longer, his own strength could not be left behind.

So he ran to Xu Yan all day long, there are many books that simply record spells, and the five element spells are a lot of them, and there are no less than thirty kinds of middle and low-level spells alone, but the power is not much different, for Qin Yu, low-level spells can no longer pose any threat, and the intermediate spells are too long to chant spells, and the practicality is poor, but refining them into spirit runes is another matter.

But after feeling the power of the small lightning strike technique, Qin Yu's interest in thunder spells increased greatly, the thunder system is domineering, it is a powerful element, and the spells are naturally extremely powerful, but it is more difficult to cultivate, and when cultivating spells, if you don't check it for a while, you will hurt yourself, and the gains outweigh the losses. Therefore, there are few thunder path masters in the cultivation realm, but those who are proficient in the thunder path are all terrifying beings in the same level, and there are few opponents.

Qin Yu has the Ten Thousand Tribulation Vajra Secret to protect his body, but he is not afraid of being injured. So he started the idea of thundering spells.

Although he has been in the house for five years, he rarely lives in Xianxia Peak, and he can only be regarded as a nodding friend to the neighbors on the left and right, looking back on the past few years, most of the time has been spent in the glass cave.

After a few years of cultivation, he has developed a cautious habit, which is why he did not take out all the elixirs at once, and if he took out more than thirty strains at once, he would inevitably become the target of public criticism, and some of his little secrets might not be able to be kept.

But those elixirs must be dealt with, but it is not yet time.

After advancing, he could feel that Xiao Bai's toad liquid effect was only about sixty percent of the previous one, if he advanced to the twelfth layer of qi training, I am afraid that there would only be three or four left, he took out those waste pills from the storage belt and fed them to the little guy again.

At this moment, a flash of inspiration suddenly flashed in his mind, and he slapped the door of his head and shouted: "Oh! I seem to have thought wrong from the beginning, Xiaobai is a spirit beast, and he can cultivate by directly absorbing the essence of plants and trees, and it doesn't have to be a refined elixir!"

He also took out an elixir in order to verify what he thought in his heart, and released Xiaobai, Xiaobai was really attracted by the aroma of the herbs, Qin Yu was overjoyed when he saw this: "It's really effective! I still have more than thirty elixirs, if I feed them all to Xiaobai, maybe I can make it advanced again, so that the problem of cultivation will be solved!"

Putting away the elixir, Xiao Bai immediately croaked at him with dissatisfaction, Qin Yu ignored it, dragged the little guy and threw it into the storage bag.

Xuanshu Pavilion.

For more than ten days, he was immersed in the Xuanshu Pavilion, and he actually found some of the cultivation experience of his predecessors and brothers, and benefited a lot, but the thunder technique he wanted the most was still not found.

He quickly flipped through a book, but he roughly went through one book after a cup of tea, and then watched the next one, at this speed, he could read hundreds of books a day, which was many times faster than the average person.

Suddenly, he sighed lightly, and seemed to have some interest in the book in his hand, and when he looked back at the writing, he saw that it was written - "Linggen Shallow Talk".

Just a simple glance, he exclaimed, this book actually recorded all kinds of spiritual roots in the cultivation realm, common, rare, and legendary. At a glance, Qin Yu didn't even know each other.

Seeing that it was not early, he took the book in his hand, and walked to Uncle Xu with those few cultivation experiences, paid the spirit stone, and copied a copy.

Xu Yan was extremely polite to Qin Yu, and his face was pleasant, after all, there were few low-level disciples as generous as Qin Yu, and he regarded Qin Yu as a cash cow.

"Is that all there are these? Master Qin's nephew has been in the Xuanshu Pavilion for more than ten days in a row, and he still hasn't found the thunder system magic books?"

Qin Yu sighed, shook his head, and said, "No." Thanks to Uncle Shi's care these days, my junior won't be here tomorrow. ”

"Well...... That kind of rare magic, most of the people who are proficient in it are kept as treasures, who is willing to donate it to the sect. In that case, I'll give you a place to go. "Xu Yanshen said mysteriously.

As soon as Qin Yu heard this, he knew that Xu Yan must know something, and said happily: "Could it be that the predecessors know who in this sect has such classics??"

"That's it, don't you say who I am, Xianxuanmen, there's nothing I don't know!"

He deliberately whetted Qin Yu's appetite, took a sip of tea, and Qin Yu was very anxious when he saw it, so he said unhurriedly: "Senior Brother Qi Hong of this sect, he has studied Lei Dao quite a lot, there should be something you want, but Senior Brother Qi Hong has a withdrawn personality and has always disliked people, if you really go, be careful yourself, don't offend him in words." ”

Qi Hong! This name Qin Yu is not unfamiliar, Gao Shan's master is him, Gao Shan left a message before leaving, asking him to be careful of Qi Hong.

Gao Shan naturally has a reason for saying this, this person should be extremely difficult, or it is better to be less troublesome.

But it can be regarded as more or less news, Qin Yu took out two spirit stones and saluted Uncle Xu before turning around and leaving.

Back in Liuli Cave, he first took out those few cultivation experiences, these experiences are not suitable for everyone, of course Qin Yu will not copy the above theories, but just learn from the experience of a large number of predecessors, so as to find a way of his own.

After repeated verification, he gradually found some ways and benefited a lot.

After practicing for a day, I fed the Han Toads some food, and then I remembered the book "Spiritual Root Theory", and after opening it and taking a few cursory glances, the whole person was suddenly stunned.

In the book, there are more than 300 kinds of spiritual root physiques recorded.
