The third blood pool is the most test of people. Even if a genius is a genius, the gap will be very big after entering the third blood pool.

Jingwuhun is at a disadvantage, while beast martial soul has a strong advantage.

Lin Feng kept observing and found that Lei Gang had been practicing in the third blood pool for 81 days, and his potential seemed to be comparable to Lu Yu.

Xuanmeng and Zhang Ruoyao both performed very well. Both of them persisted for 72 days and gained great benefits. The mortal blood turned into precious blood, and their strength increased greatly.

Those who can stay in the third blood pool for 64 days can be considered rare geniuses.

And the twelve sects combined, there are actually many such geniuses.

After walking through the three major blood pools, the blood refining stage ended, and then climbing to the seven-story stone tower.

Someone has tried it before. The first stone tower will limit the cultivation level of the person entering the body to the fourth level of body tempering, that is, the first level of bone refining. There is a ten-fold gravity field there, combined with the rich spiritual energy, which is a good place for bone refining.

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

The ten times gravity field is difficult, but Lu Yu is not affected.

On the inner wall of the stone tower, some bone forging methods are engraved, ancient and exquisite.

Lu Yu was understanding these bone-forging methods, and Wuxiang and Wanfachio in the Beidou Seven Star System were helping him deduce and improve it.

There are many people practicing on the first floor of the stone tower. Lu Yu found a secluded place, closed his eyes and sat cross-legged, and soon entered the realm of martial arts. He vaguely heard a sound of bone-forging, as if a master was beating the bones of his body, making a mysterious sound, revealing a certain rhythm and containing some changes.

This sound of bone-forging can be combined with bone refining to form a wonderful sound wave oscillation, thereby tempering the bones.

Most people cannot notice it, but Lu Yu has the Pool of Wanfa in his body and Wu Xiang helps to deduce it, and he quickly grasped the mystery.

There are 206 kinds of knocking sounds, corresponding to the 206 bones of the human body. This is iron-clad and extremely hard.

When Lu Yu was in the Qingshan Sect, he did not train well.

The reason why he was able to challenge him above the level was mainly based on the Baichuanzhi.

Now, with such an opportunity, he certainly won’t give up. He wants to cultivate every realm to the limit and lay the strongest foundation for himself.

Lu Yu's innocence can mobilize the blood and energy of the whole body, use divine blood to combine the power of the ten meridians to refine every bone in the body, and cooperate with the sound of knocking to understand the method of tempering iron bones hidden in the first layer of the stone tower.

This method can temper the bones of the whole body to be as hard as steel and indestructible.

However, it requires a lot of resources and is easily overlooked by ordinary people.

Lu Yu took out a large amount of spiritual pills, combined with the rich spiritual energy in the tower, and practiced the iron bone tempering method to the small-scale realm in just seven days.

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

These bone patterns are condensed from a large amount of spiritual energy and require huge consumption.

Ten days later, Lu Yu's iron bone tempering method was finally completed, and his bones were engraved with mysterious bone patterns, as hard as iron, and it was hard to hurt swords.

Lu Yu was not complacent, he continued, determined to reach the level of Great Perfection, and his whole body bones were refined into iron bones. At that time, he was determined to be strong and had unparalleled combat power!

Lu Yu practiced in the first stone tower for a month and spent thousands of spiritual pills. In an environment of ten times the gravity, he finally refined a body of iron bones. When he was circulating his heart, his whole body skeletons roared, and a sound of knocking echoed in his internal organs.

Cooperating with the Nine Yang Immortal Golden Body, Lu Yu felt that his foundation had improved again!

At this time, Lu Yu climbed 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 is not something that people at the fifth level of body tempering can withstand.

There are crowds of people outside the stone tower, but Lu Yu analyzed that those who can climb the second stone tower will never exceed three levels.

Lu Yu was strong and with great pressure, looking around the situation on the second floor, he saw Lei Gang at a glance. He sat cross-legged in the center, his body full of blood and blood, like a tiger, emitting a terrifying aura.

This guy is really strong.

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

There are many other geniuses, and Lu Yu didn't pay too much attention because he didn't know him.

Walking into the second floor of space, Lu Yu was about to take a look at whether there was a method of refining bones here.

I didn't expect that I was stopped by someone just after taking a few steps.

Dodge, the good dog will not block the way.

An arrogant voice came, and an arm was horizontally placed in front of Lu Yu, not allowing him to go over.

Lu Yu turned his head and looked at the man, who was in his early twenties and wearing a brocade robe. He was about the same height as Lu Yu, but he was much taller than Lu Yu.

You want to find something?

Lu Yu sneered, this guy obviously couldn't get along with him sincerity.

If you don’t agree? Then just go through two moves.

Wang Siqiang raised his sword eyebrows and pretended to be disdainful.

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

It’s better to use two moves, so as not to keep some uneasy guys looking for trouble.

Lu Yu slapped it casually, and the bones in his body exploded, as if a wild beast had awakened, and his body's strength surged.

The posture is pretty good, but unfortunately I haven't taken it to heart yet.

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

Lu Yu did not let him go, and waved his arms to block it. The huge impact force hit Lu Yu's arm, causing him to shake violently.

This is arrogance, even if you dare to fight with me!

Wang Si smiled strongly, and felt that Lu Yu was weak.

Your mosquito slap is not very good.

Lu Yu retorted and was angry that he deliberately tried his iron bones and saw how he was defensive.

If you dare to talk back, you will lie down.

Wang Siqiang roared and punched out, the bones in his body roared, and his spine was like a giant dragon, circulating the power of his body and gathering on his right fist.

Wang Siqiang's body was like stir-frying beans, crackling and constantly making noises. The fierce fist power was very terrifying. In the field of tempering the fifth level, it was quite good.

Lu Yu waved his arm and parryed with only three points, aiming to test the hardness of the iron bone.

Bang bang bang, Lu Yu kept retreating, his arms and sleeves shattered, looking quite struggling.

This kid is almost finished, and he will probably be disabled in all limbs and kneel down and beg for mercy.

Judging from his performance, he will definitely lose.

Many people gloat about the misfortune and laughed at him.

You have only this little effort, aren't you full?

Lu Yu resisted hundreds of punches in a row, feeling strong and unharmed. Without relying on the Nine Yang Immortal Golden Body, his defense has improved several times more than before.

Frivolous, kneel down!
Chapter completed!
