The third blood pool is the most testing place, even if it is a genius Tianjiao, after entering the third blood pool, the gap will be very large.

The Jing Martial Soul is relatively disadvantaged, while the Beast Martial Soul has a strong advantage.

Lin Feng had been observing, and found that Lei Gang had been cultivating in the third blood pool for eighty-one days, and that potential seemed to be on par with Lu Yu.

Xuan Meng and Zhang Ruoyao both performed very strongly, both of them persevered for seventy-two days, and gained great benefits, and their blood turned into precious blood, and their strength improved greatly.

Those who can stay in the third blood pool for sixty-four days can be regarded as rare Tianjiao.

And the twelve sects combined, there are a lot of such Tianjiao.

After walking through the three major blood pools and ending the blood refining stage, the next step is to climb the seven-story stone tower.

Someone has already tried before, the first layer of the stone tower will limit the cultivation of the person entering to the fourfold realm of quenching the body, that is, the first realm of bone refining, where there is ten times the gravity field, combined with the rich aura, it is a good place for bone refining.

The first floor of the stone pagoda is a huge space, somewhat similar to the situation inside the Kaimai Pagoda.

The tenfold gravity field was difficult, but Lu Yu was unaffected.

On the inner wall of the stone tower, there are some methods of forging bones, which are ancient and exquisite.

Lu Yu is comprehending these methods of forging bones, and the Wuzhong Wuxiang and Wanfa Pool in the Big Dipper System are helping him deduce and improve.

There were many people cultivating on the first floor of the stone tower, Lu Yu found a secluded place, the whole person sat with his eyes closed, and soon entered the realm of martial arts, and vaguely heard a sound of forging bones, as if a master was beating the bones of the whole body, making a mysterious sound, revealing a certain beat, containing a certain change.

This bone-forging sound can be combined with bone refining to form a wonderful sonic oscillation, which quenches the bone.

Ordinary people can't notice it, but Lu Yu has Wanfa Chi in his body, and Wuzhong Wuxiang helps him deduce, and he quickly grasps the mystery.

"Two hundred and six beating sounds, corresponding to two hundred and six bones of the human body, this is iron and strong, extremely hard. ”

At the beginning of the Qingshan Sect, when he was in the bone refining stage, Lu Yu had not been tempered well.

So he was able to leapfrog the challenge, mainly relying on Baichuan Mai.

Now, with such an opportunity, of course he will not give up, he wants to cultivate every realm to the limit and lay the strongest foundation for himself.

Lu Yu's heart and strength can mobilize the blood and qi of the whole body, use the divine blood combined with the power of the ten veins to refine every bone in the body, and with the sound of beating, he comprehended the method of refining the iron bones hidden in the first layer of the stone tower.

This method can temper the bones of the whole body into steel and indestructible.

But it consumes a lot of resources, and it is easy for ordinary people to ignore it.

Lu Yu took out a large amount of spirit pills, combined with the rich spiritual energy in the tower, and cultivated the iron bone quenching method to the Xiaocheng realm in just seven days.

Lu Yu noticed that a bone pattern appeared on the bones of his whole body, which had the miraculous effect of enhancing hardness.

These bone patterns are formed by the condensation of a large amount of spiritual energy, which requires a huge consumption.

Ten days later, Lu Yu's iron bone quenching method was practiced to the fullest, and the bones of his whole body were engraved with mysterious bone patterns, which were as hard as iron, and the sword was difficult to hurt.

Lu Yu was not complacent, he was still continuing, he was determined to reach the level of great perfection, and the bones of his whole body were refined into iron bones.

Lu Yu cultivated in the first layer of the stone tower for a month, spent thousands of elixirs, and finally refined into an iron bone in the environment of ten times the gravity.

With Jiuyang's indestructible golden body, Lu Yu felt that his foundation had improved again!

At this time, Lu Yu ascended to the second floor of the stone tower, and a terrifying gravity acted on Lu Yu, shaking his bones all over his body.

"Forty times gravity!"

Lu Yu was a little surprised, this kind of force field was not something that a person in the five-fold realm of quenching could withstand.

Outside the stone tower, there are a lot of people, but Lu Yu analyzed that the people who can climb the second layer of the stone tower will never exceed the third floor.

Lu Yu was iron-clad, under tremendous pressure, looking around at the situation on the second floor, he saw Lei Gang at a glance, he was sitting cross-legged in the center, full of blood and blood, like a fierce tiger, exuding a terrifying momentum.

"This guy is really strong. ”

Lu Yu looked away and saw Long Zhen again, he was also extraordinary, and he could see that his strength had improved a lot.

There are many other Tianjiao, and Lu Yu didn't pay much attention to it because he didn't know him.

Walking into the second layer of space, Lu Yu was going to take a look first to see if there was a way to refine bones here.

As soon as he took a few steps, he was stopped by a person.

"Get out of the way, good dogs don't get in the way. ”

An arrogant voice came, and an arm was placed across Lu Yu's face, preventing him from passing.

Lu Yu turned his head to look at the man, in his early twenties, dressed in a brocade robe, about the same height as Lu Yu, but much more burly than Lu Yu.

"You're looking for something?"

Lu Yu sneered, this guy obviously couldn't get along with himself sincerely.

"If you are not convinced, then two tricks. ”

Wang Siqiang raised his eyebrows, pretending to be disdainful.

Lu Yu looked around and found that many people were watching with their eyes open, obviously very interested.

"It's good to make two moves, so as not to let some blind guys always find fault. ”

Lu Yu slapped his hand, and the bones of his whole body exploded, as if a brute beast had awakened, and the strength in his body skyrocketed.

"It's pretty good, but unfortunately I haven't taken it to heart. ”

Wang Siqiang mocked, and his right hand punched out, three times faster than Lu Yu's move, and instantly landed on Lu Yu's chest.

Lu Yu didn't dodge, he waved his arm to block, and the huge impact hit Lu Yu's arm, shaking him violently.

"With this bit of strength, you dare to fight me, it's arrogant!"

Wang Siqiang smiled, feeling that Lu Yu was weak.

"You don't do much at swatting mosquitoes. ”

Lu Yu retorted, and was angry, he deliberately tried his iron bones to see how his defense was.

"Dare to talk back, get down for me. ”

Wang Siqiang roared, a punch blasted out, the bones in his body contended, and his back was like a giant dragon, using the power of his body, converging on his right fist.

Wang Siqiang's body was like frying beans, crackling, non-stop, and the fierce fist strength was very terrifying, and it was quite not weak in the field of refining the fivefold realm.

Lu Yu waved his arm to parry, and only used three points of force, aiming to test the hardness of the iron bone.

Bang bang, Lu Yu kept retreating, the sleeves of his arms were torn, and he looked quite struggling.

"This kid is almost finished, and he is expected to be crippled on all fours, and he will kneel on the ground and beg for mercy. ”

"Judging by his performance, it's a sure defeat. ”

Many people gloated and laughed.

"You just have this little strength, haven't you eaten enough?"

Lu Yu parried hundreds of punches in a row, feeling iron-clad and undamaged, without the help of Jiuyang Immortal Golden Body, his defensive power has increased several times compared to before.

"Frivolous, kneel for me!"

Wang Siqiang roared, and the power of one punch exploded the void, causing ripples, and the spread of the fist power was breathtaking.
