Fengyun kept holding the knife in motion, as if it possessed some magical power, so that his gaze could not take his eyes off it.

Just if you look closely at Fengyun's eyes, you will find that his eyes are in a dull state, and it is obvious that his attention is not on the knife in his hand at all.

In fact, eyes can deceive, and Fengyun's attention is indeed on the knife, but in a different way.

He is now trying to figure out the internal structure of the knife, more precisely the internal structure of the metallic aggregate that makes up the main body of the knife, through his senses.

While he was worried about trying to keep the stone pillar from being destroyed, he suddenly realized that it was necessary for him to advance the progress of his self-created exercises, so that it would have new content.

If he could master the power of the metallic totem again, he would be able to protect the stone pillar, and he had seen the destructive power that metallic aggregates could create.

Even if he had just added the part related to metallicity to his self-created exercises, he was not skilled enough to make it exert too much power, at least not compared to the totemic power he created earlier that could be transformed into various attributes, but given the characteristics of metallicness, it would not be far behind.

If he could protect the pillar with the power of the metallic totem, he believed that the monsters that could destroy the pillar should become very few.

According to his understanding, whether it is a brute beast or a monster, it is actually quite cautious, unless it is forced to, under normal circumstances, it will not take risks casually, because once injured, it is possible to face death, after all, it is much easier to hunt the target of an injury.

In other words, brute beasts and monsters are injured, and they are very easy to fall prey to other brute beasts and monsters, not to mention, the injury itself can lead to death.

Therefore, as long as the monster realizes that destroying the stone pillar will bring risks, it basically will not take risks, after all, the stone pillar is just a stone pillar, and it cannot be eaten or drunk, even if the monsters are extremely hungry and attack it, they will not get any benefit.

In fact, the more hungry the monster is, the less likely it is to do things that don't see benefits.

It's just that the premise of all this is that he must be able to use the power of the metal totem to protect the stone pillar, and this requires him to create exercises related to the metal part.

Without much hesitation, he made up his mind to create the metallic part of his self-created exercises, after all, he had been prepared to do so for a long time.

It's just that at that time, he was worried about the situation of the Golden Dragon Tribe, so he had to choose to put it on hold for the time being, and now the situation has changed.

Not to mention that Lan Zhu's new operation method was developed by the White Snake, which greatly improved the safety factor of the warriors, let's just say that he is now blocked in front of the space hole, cutting off the path for the monster to enter the space where the Golden Dragon Tribe is located, so that the risk that the Golden Dragon Tribe has to face is greatly reduced.

As for some of the fish that slipped through the net, there were white snakes, and they couldn't make much of a storm.

Fengyun realized that he was no longer needed to help the Golden Dragon Tribe deal with the risks, and this played into his hands, allowing him to concentrate on creating the metallic part of the exercise.

He's starting to do this now, it's just a coincidence, and even if he doesn't need to use the power of the metal totem to protect the stone pillars, he'll do so in the near future.

Feng Yun's process of creating the metallic parts of the exercise was relatively smooth, at least much smoother than the ones he had created before.

Thanks to the fact that he had subdued the metallic aggregate, he used his sense to explore its internal mechanisms without encountering the slightest obstacle, and he could even manipulate the metallic aggregate to give him a more detailed understanding of its interior.

It didn't take him long to get a clear picture of the inside of the metallic aggregate, and all that was left was him to create the part of the exercise that was metallic.

In this regard, Fengyun is still very confident, after all, he has created the three parts of water, fire and earth before, which can be regarded as quite experienced, after all, although the attributes of each part are different, the basic principle is the same.

However, when he actually started to create it, he realized that he had underestimated the difficulty.

The power of the metallic totem is not only a good hand for injuring the enemy, it is not easy to control, and it is also unambiguous for injuring oneself.

Fengyun was in trouble from the very beginning of his work on creating a technique for metallic properties.

He had just copied the internal structure of the beginning metallic aggregate into his own body, and found it quite difficult to do so.

If you have to make an analogy, the core structure of the three parts of water, fire and earth that he created before was built with wood, but now he has to build it with metal, and what is even worse is that these metal components still need to be made by himself, which is not ordinarily difficult.

Fortunately, he had already subdued the metallic aggregate, and he could extract metallic energy from it to make components, and then construct the core structure of the metallic part of the exercise.

Even so, it is still quite difficult to really carry it out, and the first thing to do is the damage caused by metallic energy to his body and meridians, especially the latter, which is the basis for the existence of the exercises, and there is no room for any loss.

But no matter how careful he was, introducing metallic energy into his body would be equivalent to sending a knife into his body, and it would be extremely sharp, and it would inevitably hurt him.

Although thanks to the fact that he had already subdued the metallic aggregate, he had a high level of operation on the metallic energy obtained from it, and if he found that something was wrong, he immediately stopped, so that the damage he received was relatively slight, but it was still a serious drag, and the progress of his own self-created exercises.

The fear of causing irreparable damage to himself made him timid.

In the end, he thought of the five phases of restraint and used the power of the fire attribute totem to protect it, mainly to wrap the metallic energy extracted from the metallic aggregate, and destroy part of it before it could cause damage to his body.

Although this would cause Fengyun to lose some of his metallic energy, it also allowed him to let go of his hands and feet, and greatly accelerated the creation of exercises related to metallic parts.

After a lot of hard work, Fengyun finally succeeded.

"Phew!"

Fengyun took a breath of turbid breath and relaxed, and then he felt that he had become very tired, both mentally and physically, even more tired than fighting a strong enemy, and in order to succeed, he could be said to have put all his heart and soul into it.
