Qin Yu took out more than twenty demon cores in the late stage of qi building, exchanged them for thousands of spirit stones, plus hundreds of spirit stones from the dead ghost Chen Hong's storage bag, and went to buy five Guiyuan Pills.

He returned to the stone room of the cave to meditate, and went down one by one, running the nine immortal scriptures, the flesh and blood turned, the sea of life boiled, and the light golden light exploded, filling the entire stone room, as if all of them were dyed gold, and for a while the golden light was brilliant and brilliant.

Qin Yu sat cross-legged, and the spiritual power of Guiyuan Dan continued to infiltrate into his body, strengthening Qin Yu's breath, strengthening his muscles and flesh, nourishing his limbs and bones, and finally returning to Yuan into the sea, making the sea water of Danhu Lake in the Sea of Life more abundant.

Qi building realm is the second realm in the cultivation realm, and it is also the basic realm of qi refining, but only by laying a solid foundation can you become stronger step by step in the future cultivation process.

Qin Yu urgently needs strength, he needs to become strong, break through the foundation refining realm as soon as possible, and set foot in the innate realm! Only by entering the innate realm can he become an inner disciple, a sect disciple in the true sense, be respected, and obtain more advanced ground-level martial arts and supernatural powers.

Stepping into the innate realm, it is said that the body can produce essential changes, the acquired qi of the mission sea, turn into the innate qi, and the life of the sea Danhu is more pure, remove the acquired impurities of the body, become like a celestial man, return to the kind of crystal clear and unadulterated when the baby is born, the blood is clean and unclean, the life span is extended, and the life span can be extended to 200 years old.

The Great Perfection of Qi Building, at most to live to be 150 years old, many monks because of years of penance and fierce battles, blood refining and tempering, depletion of the source, often 120 years old, has already come to an end. Unless you take a lot of high-quality pills, you can resolve the subtle scars of the body, the loss of origin, etc.

When all the five Guiyuan Pills were absorbed, Qin Yu opened his eyes, and a bolt of lightning flashed between the opening and closing, the sharp edge was sharp, his cultivation had improved slightly, but it was far from enough, his body was like a bottomless pit, even if he wanted to cultivate to the fifth layer of Qi Building, he would need more than a hundred Guiyuan Pills, that is, tens of thousands of lower grade spirit stones.

Next, he had bitten more than a dozen demon cores of second-level peak demon beasts, turned into rolling demon power, and was absorbed, and even improved his cultivation a little, but it was still not enough.

"One lacks contribution points, and the other lacks spirit stones!" Qin Yu was helpless, he retreated for one night, and it was time to go to the mission hall to meet Ji Qianqian.

When you return from the Earth Demon Abyss, it's time to go to the Lonely Mountain Range.

When he pushed the stone door, he found that ten zhang in front of the stone gate, there was a burly man sitting cross-legged, with marks on his face, after sensing the opening of the stone door, he also opened his eyes, his eyes were fierce, he stood up, and said: "I just came back from the outside experience, I heard that this year's top 100 disciples have been born and obtained the cave mansion of the mountain range, you want this one, now you hand over the cave house jade slip and leave here, otherwise, don't blame me for being ruthless!"

"Who are you, so arrogant!" Qin Yu snorted coldly.

The scar man said in a cold tone: "I have been trapped in the peak of Qi building for many years, half-step innate realm, and the mountains and rivers list is ranked ninety-seventh, so many people call me Meng Jiuqi, remember, my real name is Meng Ao, one of the top 100 newcomers nine years ago!"

"The top 100 newcomers before the last three sessions, don't you have your own cave mansion?" Qin Yu asked curiously.

"Over thirty years old Qi Realm, whether it is a top 100 or a master of the mountains and rivers list, the cave will be taken back, and if it is a kind of admonition and spur, there is not much time to break through, the potential is exhausted, and I have to go crazy. ”

"Since you were one of the top 100 newcomers and represent good potential, why have you not been able to break through after three sessions?"

Meng Ao said in a stiff tone with a look of arrogance and coldness: "Because, in addition to cultivating the Qingyang Jue, I also have another method of cultivation, and at the same time I have cultivated a stunt, which consumes a lot of time, and because I have no background, the first three years, the cultivation is too low, the cave was snatched away by others, and I have no ability to go out to do tasks, so I have delayed three years of precious time, and the progress is slow. ”

After listening to the other party's words, Qin Yu fell silent, this person's experience was very enlightening to him, because of his own cultivation of the Immortal Sutra, and because of the special nature of his body, he needed a large amount of pills and aura, he must hurry up, he can't be like this Meng Ao, at the age of thirty, he still can't break through.

"That's the, it's time for you to decide. ”

"It's not easy to practice for a while, let's have a fight, if you lose, I won't hurt your foundation!" Qin Yu said.

"You! are even more arrogant than I am!" Meng Ao almost got angry, and stood up with a gloomy face.

"Whew!" Meng Ao laughed a little fiercely, without saying a word, he directly started his hand, and a punch was blasted out, and the true yuan on his arm boiled, wrapping his fist, as if an energy bomb smashed over.

He didn't move his sword at all, because he didn't feel the need anymore.

Regardless of cultivation, experience, exercises, or swordsmanship, Meng Ao has the confidence to easily defeat the other party, a boy who doesn't know the height of the sky.

"Bang!"

Qin Yu's body rushed forward, like an afterimage, and it was also blasted out with a punch, the power was extremely violent, and even with the wind that broke through the air, crushing the air and directly exploding.

The two fists collided, Meng Ao's face changed, his arm spasmed, and all the fist bones were broken.

The strength of his punch is enough to tens of thousands of catties, this is still in the body quenching, building the qi realm, repeatedly sharpening the body, and when building the qi realm, he has taken the strong bone pill, the marrow washing pill, the blood washing pill, the peiyuan pill, etc., repeatedly refining the flesh body, turning around to strengthen the foundation, the flesh and blood power he is proud of, but it is still not as good as this young man.

"Your physical body is very strong, but your cultivation is too low. Meng Ao snorted coldly, a storage bag, a flash of brilliance, and an extra flying sword in his hand.

"This is my blood-draining sword, which can break the flesh of a cultivator of the Innate Realm, even if your flesh is like a treasure body, it will be pierced through the hole!"

Qin Yu frowned, he had already felt the cold aura on the opponent's sword, it was indeed a threat to him, it was estimated that it was not as simple as a magic weapon, maybe it was a spirit weapon flying sword.

Unless he cultivates to enter the innate realm, he can combine the Gang Qi released from the surface of his body with the treasure body, biochemical again, and the runes and flesh and blood are blended, and the flesh and blood at that time is not just a physical organization, it is a body cultivation.

"Evil Sword Technique!" Meng Ao roared, his breath bloomed, piercing to the bone, urging the blood sword, around him, an illusory sword shadow appeared, the sword qi was vertical and horizontal, and the killing opportunity was infinite.

"First sword!" Meng Ao pinched the sword trick, and the blood-draining sword came out of his hand, steaming, showing a fierce sword, as fierce as blood, a red light, roaring.

Qin Yu didn't have a magic weapon, so he had to quickly seal with both hands, and the Xuan Snake struck three times, and the first blow slammed out.

The energy exploded, and with a bang, the flying sword was knocked upside down, and Qin Yu was also churning in blood and blood, retreating again and again, mounted on the stone door, and was dragged by the air control cover in front of the door.

Meng Ao's face changed again, his own spirit weapon flying sword, coupled with the sword technique of Xuangong's top-grade swords, could not even defeat this young man?

At this time, it was no longer a question of the ownership of the cave, but Meng Ao's swordsmanship and cultivation were shaken, and he persisted for nine years and failed to break through.

"Impossible, second sword, mountain slashing style!"

Meng Ao frantically urged a body of cultivation, the majestic spiritual power rolled out, and the sword technique was blessed again, making the deterrence of the blood-draining sword stronger, producing a sword several zhang long, even more domineering than just now, and the sharpness was incomparable.

"Kill!"

Qin Yu also moved all his strength, rushed forward again, his hands were sealed one after another, the second and third blows of the Xuan Snake erupted, and blasted out, in front of him, there seemed to be a shadow of a black water Xuan Snake emerging, it was the condensation of true vitality, and it was so ferocious that it actually confirmed a trace of righteousness.

Boom! Boom!

Meng Ao's flying sword was shocked again, and he also vomited blood, his face full of horror.

Qin Yu also vomited blood, but his body was not seriously damaged, turned into a ray of light, and rushed over, not wanting the other party to send another third sword, otherwise it would be too difficult for him to block it.

In fact, he overestimated Meng Ao, half-step innate realm, although it was no problem to send out these two swords, but after the two sides collided, the huge force had already injured the other party, and in a short time, it was also a little difficult to continue to send out a powerful third sword.

Qin Yu used the Great Barbarian Giant Spirit Fist to fight in close combat, Meng Ao held the flying sword and unfolded his swordsmanship, but he couldn't urge the sword trick to move, because he needed to cast time and gather spiritual power, and now once he got close, he was interrupted, and he could only fight with the basic sword technique.

Of course, this is mainly because the cultivation and swordsmanship of sword cultivation are too low, if it is those ancient powers, swordsmanship is all over the sky, and it can be used casually, without urging and condensing time, it can continue to explode, that is the true meaning of sword cultivation.

"Ahh
