The appearance of the Blue Fog Zone, the Open Vein Pagoda and the Quenching Stone Pagoda attracted the attention of all the masters of the twelve sects of Tianqing Prefecture.

However, in the depths of the blue fog area, there are unknown changes.

Many monsters are mutating, and their strength is also improving rapidly.

Somewhere in a mist-shrouded valley, on this day there was a roaring sound from the ground, a stone peak rose from the ground, shaped like a pagoda, and many caves were distributed, erupting with glow, and terrifying energy waves were being released.

Countless demon beasts converged towards this valley, and they all burrowed into those caves, obtained the opportunity to create, and cultivated in them.

In the mist, a black fox ghostly searched for the surrounding movements, and looked at the stone peak with small eyes, revealing a scorching greed.

This black fox has a bunch of silver hair on its forehead, which looks particularly eye-catching.

With a brisk and dexterous pace, he entered the valley and burrowed into the mysterious pinnacle.

At the top of this stone peak, there is an ancient stone platform with a huge stone drum on it, full of the vicissitudes of time, engraved with the lines of heaven and earth.

In the valley, the fog is getting thicker, the blue mist is churning, and the spirits of demon beasts are dancing.

A sika deer walked into the valley, and it turned out to be Xiao Wu who followed Lu Yu to Tianxuanzong.

Looking at the demon souls dancing in the mist, Xiao Wu said to himself: "The soul of the war beast, the war drum of heaven and earth!"

Xiao Wu disappeared into the mist, but the soul of the war beast in mid-air became more and more dense.

Bai Xue and Hua Yujiao spent two months, under the guidance of the Beidou Martial Arts System, absorbing enough demon beast essence blood from the first blood pool, and cultivating the blood refining to the Great Perfection, and then entering the second blood pool.

The two girls have excellent appearances, but because they are Jing martial spirits, they are generally talented in martial arts cultivation, if they are not fused with the Big Dipper Seven Star System, it will be difficult to pass the level of blood refining alone.

Many masters of the Twelve Xuan-level Sects have integrated into the martial arts system, which is a proud work from the Beichen Holy Gate in the past, and in the process of reshaping the foundation, countless people have benefited.

The second blood pool made many people stop, Bai Xue and Hua Yujiao were insisting, they didn't seek speed, they worked slowly and carefully.

This requires patience, and many people give up because they can't stay in the pool of blood for too long and feel that one entry and one exit is too troublesome.

Cultivation is important in persistence, this is a chance, but unfortunately many people don't think so.

Lin Feng was cultivating in the third blood pool, and he could already stay for two hours at a time, and his progress was very fast.

The blood pool can further stimulate the potential of the human body and improve the quality of blood, as long as you persist, you will reap the rewards.

Many people walked through the three blood pools, and finally all the blood turned into precious blood, and the whole body was full of qi and blood, and the foundation was firm.

"Let's go, let's give it a try. ”

Seeing that there had been no other opportunities in the blue mist area, the sect elders and masters of all factions couldn't help it, and they all entered the Open Vein Pagoda and the Blood Pool, intending to cultivate from scratch.

Some people are too old, their qi and blood are decaying, and the effect is mediocre.

There are also people who strengthen the martial arts, and all blood is turned into precious blood, which makes the longevity greatly increased, and the people are much younger.

"If you can move this Open Vein Pagoda, Blood Pool, and Stone Pagoda back to the sect, it will definitely be a great creation, and you can cultivate countless outstanding Tianjiao in the future. ”

"It's a good idea, but it's a pity that I can't move it. Moreover, the blood pool is a consumable, and with so much demon beast essence blood, ordinary sects can't get it together. I guess that this pagoda and blood pool are probably the cultivation secret places of a holy place somewhere in ancient times, specially used to cultivate the world's pride. ”

"Pagodas and blood pools can fully stimulate the potential of the human body, lay the strongest foundation, and provide a solid foundation for subsequent cultivation. It's no wonder that the Ancient Holy Land is extremely powerful, and this alone is not something we can compare. ”

On the second floor of the stone tower, Lu Yu's bronze bone cultivation took twenty-five days to be preliminarily completed.

Compared with the iron bones, Lu Yu found that the copper bones were engraved with five-fold bone patterns, and the iron bones were engraved with three layers of bone patterns, which was the essential gap, and the power was naturally different.

The bronze bone is further deformed on the basis of the iron bone, the bones of the whole body bloom with golden light, and the five-fold bone pattern is perfectly combined, containing the explosive power of the primeval beast, which is indestructible and like thunder!

Lu Yu's bronze bones were first formed, and he did not leave immediately, but continued to consolidate, and it took more than a month to quench his copper bones to the stage of Great Perfection.

At that moment, the sound of swords fighting in Lu Yu's body came out, and when the bones exploded, it was like thunder, breaking people's souls.

Lu Yu got up, like a god, with bronze bones, containing supreme murderous aura, and wanted to suppress all strong enemies in time.

It was a momentum, invisible and terrifying.

The divine blood in Lu Yu's body nourished the muscles and bones of his body, making his skin glow with a pale yellow light, as if there was an ancient killing god lurking in his body.

Looking around, Lu Yu found that Lei Gang and Long Zhen were gone, and Hu Qianluo, Huo Donglai, Xie Wanfeng, Nie Weihua and other Tianjiao also left, probably going to the third floor of the stone tower.

Zhang Ruoyao and Xuan Meng were cultivating nearby, Lu Yu stepped forward to wake them up, and taught them the method of iron bones and copper bones that he had comprehended, so that they should not be anxious, and first cultivate the iron bones to the Great Perfection, and then cultivate the copper bones.

The third layer of the stone tower is extremely terrifying, there is a hundredfold gravity field here, as soon as Lu Yu entered, he felt that the bones of his whole body exploded, as if they would collapse at any time with the power of ten thousand jun.

"What a terrifying force field. ”

Lu Yu used the blood qi of his whole body, and the divine blood bloomed, releasing a powerful divine power, making the copper bones of his whole body resound, and supporting the huge burden.

There is a secret power flowing from this place, and the void is slightly distorted.

In such an environment, you need to fight against the constraints of the force field at all times, so that the body is kept in a high state, and the slightest carelessness will die here.

There are not many people here, only more than twenty, all of them are outstanding Tianjiao of the twelve sects, all of them are furious in qi and blood, like dormant primeval giant beasts, honing themselves and refining their muscles and bones.

Lu Yu walked around the third layer, and on the inner wall was engraved a higher-level bone refining scripture, the Silver Bone Method.

Lu Yu was very pleasantly surprised, this stone tower was very demonic, it was definitely a treasure of a certain holy gate, specially used to develop the potential of the human body.

The third layer of the stone tower corresponds to the sixfold realm of quenching the body, Lu Yu carefully comprehended the scriptures, and then concentrated on cultivation, the elixir combined with the rich aura in the stone tower is the best place to cultivate.

Some masters climbed from the second floor of the stone tower to the third floor, wanting to enter the cultivation, but found that they could not withstand the hundredfold gravity there, so they were forced to climb from the corridor to the fourth floor and entered the skin refining stage.

The fourth floor of the stone tower was obviously different from the third layer, and the inner walls were inscribed with ancient runes, releasing the power of a thousand hammers and the scorching refining qi.

It's like a big Dan furnace, and when you go in, you're almost cooked.

Compared with the Kaimai Pagoda, this stone pagoda has significantly higher requirements in all aspects, and not everyone can climb it.

If this is the standard test for the selection of Tianjiao in the Ancient Holy Land, then looking at the world, there are very few people who can get excellent results.
