At this time, Zhang Yuzhu had no intention of paying attention to Shui Sheng. He had now reached the most critical moment.

He could feel that his iron leg skill was about to be perfected.

This feeling is like the feeling when he has mastered the Iron Head Skill, Iron Cloth Shirt, Iron Sand Palm, and Iron Arm.

After this recovery, his legs felt like they were on fire, and his skin turned red. The huge heat actually dissipated some of the cold air in the cave.

The ice underneath the cave is slowly melting.

Zhang Yuzhu stopped, and the short iron rod in his hand was thrown aside.

At this critical moment, Zhang Yuzhu kept beating his legs with iron sand palms.

He adjusted his power again and again, and the power of the iron sand palm was gradually increasing.

A trace of blood gradually oozed out from his leg and flowed down slowly.

With each beating, the blood glow continued to release energy, increasing the strength of Zhang Yuzhu's legs.

The legs also began to expand and contract. Zhang Yuzhu knew that his iron leg skills were finally coming to fruition.

"boom!"

A mysterious voice exploded in Zhang Yuzhu's mind, and the skin all over his body seemed to have become one piece.

Originally, after he achieved great success in other external skills, he felt that he was not coordinated at all, but this time, he no longer felt it.

Qi and blood were rolling in his body. Under the impact of this Qi and blood, the Iron Crotch Skill and the Iron Foot Skill were also rapidly transforming at this time.

Slowly rushing towards the progress of Dacheng.

Zhang Yuzhu felt this, and he knew in his heart that this was the time for all his external skills to be accomplished.

If he misses this opportunity, he will definitely suffer a lot again.

Iron Crotch Kung Fu is not so easy to practice. Even if Zhang Yuzhu's mind is as strong as iron, he still can't bear if his vitals are hit.

Now, at this moment, taking advantage of the opportunity to break through in the Iron Leg Skill, the energy and blood are rushing away quickly. Although it hurts a bit, it is still much better than being beaten forcibly.

The blood glow is constantly releasing energy, and Zhang Yuzhu is also constantly mobilizing the energy of qi and blood according to the breathing method of practicing external skills.

This is what Zhang Yuzhu discovered only after he achieved great success in the three sects. He was actually able to mobilize the power of Qi and blood to a certain extent and constantly temper his body.

Now, at the most critical moment, how could Zhang Yuzhu not quickly mobilize his energy and blood to cooperate?

The energy and blood washed away over and over again, and the power of Zhang Yuzhu's iron legs reached the peak of success first.

As the Iron Leg Kung Fu reached a state of great success, Zhang Yuzhu's Qi and blood increased tremendously, and the energy in the blood light quickly integrated into Zhang Yuzhu's Qi and blood.

"Whoosh!"

A sound like running water appeared in the cave.

As soon as this voice appeared, Shui Sheng, who was looking at Zhang Yuzhu in confusion, was startled.

"What is this? Why is there the sound of running water here?"

Shui Sheng looked around and found no flowing water there.

Finally, she looked in the direction of Zhang Yuzhu, and she finally discovered that the sound of running water came from Zhang Yuzhu.

"How is this going?"

Maybe this world has never seen anyone like Zhang Yuzhu who has practiced external skills to this level.

Therefore, even though Shui Sheng has a father with extremely high cultivation level, he is still quite confused about this situation.

After all, if an ordinary person cultivates an external skill for a lifetime, it is already a great thing if he can practice it to a great extent.

We even have to worry about whether practicing this third-rate external skill will lead to disease and lead to early death.

Even with the help of secret medicine, it is impossible to be like Zhang Yuzhu, who can completely repair all injuries when practicing external skills.

Therefore, even if one has achieved great success in external skills, it will completely overdraw the potential in the body.

As for generating qi and blood energy, that's something you don't even have to think about.

In this world, internal strength is still the mainstream.

In the eyes of those who practice internal martial arts, external martial arts are always third-rate martial arts, and the peasant's tricks cannot be put on the stage.

It is basically impossible for Zhang Yuzhu to be able to cultivate his external skills to a state of great success in a short period of time, and to cultivate four or five external skills to a state of great success at the same time.

Even if you succeed in cultivation, you won't be able to survive for long. Your potential is really overstretched.

This is why the Blood Sword Patriarch knew that Zhang Yuzhu had mastered external skills to a great level, and didn't care at all.

After a short period of time, external skills can be easily broken as long as you have a magical weapon. This is the biggest flaw of external skills.

In the hands of the Blood Knife Ancestor, there is a magical weapon, the Blood Knife.

This blood knife is made of cold iron from the deep sea. It can blow hair, cut hair, and cut gold and jade.

Not to mention, once the external skills have been cultivated to a great level, when the time comes, as long as one is struck by a blood knife, the external skills will be broken directly.

The only thing that the Blood Knife Ancestor did not expect was that Zhang Yuzhu did not just practice an external skill.

Moreover, it is not only the achievement of one external skill, but also the birth of the power of Qi and blood.

As long as Zhang Yuzhu has mastered the seven external skills, all the external skills in his body will basically be integrated into one, and there will basically be no shortcomings.

At that time, even if the Blood Sword Ancestor has such a magical weapon as the Blood Sword, it will be difficult to deal with Zhang Yuzhu.

What's more, Zhang Yuzhu still has the power of Qi and blood, and his external skills have been cultivated to such an extent, which is simply unbelievable.

The sound of "squeaking" kept ringing, which meant that Zhang Yuzhu's energy and blood had been abundant to a certain extent.

The clothes all over his body were already soaked with sweat, because the heat of his blood was too great.

At the same time, there was an unpleasant smell emanating from Zhang Yuzhu's body.

This smell was quite foul. Shui Sheng, who was lying against the wall, was about to faint from the smell.

And he was still retching. The most important thing was that Shuisheng's acupuncture points were taped and he couldn't move. He could only suffer.

"Little thief, you stink so much!"

Zhang Yuzhu ignored Shui Sheng.

Qi and blood were constantly flushing through Zhang Yuzhu's body, and his skin became tighter and tighter.

The iron crotch skill is rapidly moving towards great success, and even the soles of his feet are constantly changing.

"Tear!"

A sound like tearing paper was heard, and the skin on Zhang Yuzhu's body gradually lost its luster.

Just like a snake, Zhang Yuzhu was shedding his skin at this time.

The skin all over his body was changed to one side, and some transparent skin fell from Zhang Yuzhu's body.

Some of the bronze and even black dead skin had completely fallen off.

The new skin is white and very elastic.

Not only that, Zhang Yuzhu actually grew again at this time. His height, which was already quite tall, actually grew a bit longer.

It used to be about 1.89 meters, but now it is over 1.9 meters.

"drink!"

A low shout came from Zhang Yuzhu's mouth, conveying an inexplicable majesty.

It had a frightening temperament, as if the person standing in front of him was not a person, but like an abyssal beast.

“Finally everything is done!”

Zhang Yuzhu's originally stern face revealed a hint of smile.

The seven external arts, when he was like a cicada, were all connected and completely completed.

At this time, the energy in the blood glow was completely exhausted, and no more energy was released.

Without the supplement of blood energy, Zhang Yuzhu, who had just achieved great success in the three sects, felt a twist in his stomach.

At this time, Zhang Yuzhu didn't care to test how powerful his defense was now. He was too hungry now.

He dodged and ran towards the place where the horse meat was hanging.

What he didn't notice was that from the time he ran to the place where the horse meat was, both the solid ice and the hard stone on the ground had cracked.

This is because Zhang Yuzhu has just made a breakthrough and has not yet mastered his own power.

There was some frozen horse meat hanging on the wall. When Zhang Yuzhu arrived, he took a piece of horse meat and ate it without hesitation.

The bone entered Zhang Yuzhu's mouth and was chewed to pieces. Blood flowed from the corner of his mouth. This scene was quite terrifying.

Shui Sheng on the side looked at Zhang Yuzhu as if he was looking at a demon.

Fortunately, there is abundant food here. Otherwise, Zhang Yuzhu would be the only external martial arts master in the world who starved to death because he had no energy to replenish after his breakthrough.

In fact, Zhang Yuzhu needed to take supplements after every breakthrough in his external skills. However, before, he had broken through one external skill at once, and with the blood light providing energy, Zhang Yuzhu did not need to take supplements.

At this time, Xue Mang has exhausted his energy due to his breakthrough, and can only replenish energy through food.
