Fortunately for Fengyun, he didn't realize that although there was a lot of metallic energy gathered at him, none of them touched his body, and all of them were absorbed by the knife with the metallic aggregate as the skeleton.

"Phew"

Fengyun couldn't help but exhale a breath of turbidity, and his tense nerves were finally relaxed, but his whole person didn't really relax.

Just because a semi-finished weapon absorbs metallic energy doesn't mean it's successful.

It was the first time he had refined a weapon like this, and no one knew what would happen next, so he had to be careful to avoid mistakes.

That's what he thought, and that's what he did, a pair of eyes glued to the half-finished weapon, watching for its changes.

Unfortunately, he was quickly disappointed, because in the current situation, it was really difficult for him to do that.

When there is more metallic energy, they begin to glow, and the brightness is quite high, and they themselves have extremely strong destructive power, even if this time they did not mean to him, but rushed to merge with the metallic aggregate, but it still made his eyes very uncomfortable.

He felt as if his eyes were being pricked with needles, but a multitude of needles kept pricking.

He had a hunch that if he didn't take his eyes off and continue to stare at the half-finished weapon, he was afraid that before it could become a finished product, his eyes would be blinded first.

Eventually, he looked away from the half-finished object, which he couldn't see clearly anyway, and besides, his eyes were very important to him and had been a huge help to him.

He couldn't imagine what would happen if his eyes were blind, even if it was only temporary, he would be unbearable.

Luckily, he didn't oversee the progress of the weapon's half-finished product, and the situation remained stable until all metallic energy was absorbed, and nothing happened.

After absorbing all the metallic energy, the brilliance on the knife began to converge, and the brightness became less and less.

Before the light had completely faded, Fengyun looked at the knife with some impatience, desperate to know what it had become.

The light converged, and the damage to his eyes was greatly reduced, and he only felt some dazzling, but he didn't feel the pain anymore.

He subconsciously opened his eyes wide, trying to see more clearly.

And he got his wish.

He saw that the gaps in the blade body, which was made up of metallic combinations, had been filled, with a silvery-white material that resembled metal.

However, unlike metal, it was also somewhat transparent, allowing him to see metallic aggregates indistinctly.

Because of this, Fengyun looked at it, and couldn't help but have an idea in his heart, the metallic aggregate is not only the structure of the knife, but also the meridians of the knife.

When the light on the knife was completely gone, Fengyun subconsciously reached for the hilt, wanting to test whether it was good or not.

But when his fingers were about to touch the hilt of the knife, he was suddenly startled and stopped, because he thought about the terrible power of metal, whether it would hurt his hand, you must know that the knife has absorbed a huge amount of metallic energy this time.

But as soon as his hand stopped, he couldn't help but approach the hilt again.

He had put so much effort into creating such a knife, and it would be too cruel to him if he couldn't even touch it.

Eventually, he touched the hilt with his fingers.

The sensation of an electric shock immediately appeared on his fingertips, but it was relatively mild, and it was completely within his acceptability, and even if the sensation persisted, he was not without phenols.

Most importantly, he didn't feel any damage to his fingers.

Now Fengyun was relieved, and he held the hilt of the knife in his hand.

That wasn't the end of it, and then he couldn't help but swing his knife.

It feels pretty good, the weight is just right, and it swings quite smoothly, as if the air resistance doesn't exist for it anymore.

The air really couldn't hold it back, because it had already cut it open in the first step.

Even if Fengyun didn't take the initiative to urge the knife, its own sharpness was already quite terrifying, cutting through the air blocking it, which was a piece of cake.

In fact, if you look closely at the place where the blade passed, you will find a crack, and the spatial barrier has been cut.

This is still the most ordinary form of the knife, and if Fengyun urges it, its destructive power does not know how many times it will increase.

The more Feng Yun wielded the knife, the more he liked it, compared to the knife he had before, even if he was a person who missed the old love, he had to admit that the gap between them was really a bit big.

Holding the knife and waving it for a while, Fengyun naturally began to use it to demonstrate his knife, from slow to fast, from simple to complex.

In the blink of an eye, Fengyun's figure was gone, leaving only a ball of light rolling around non-stop, and the sword shadow had already covered Fengyun.

If someone splashes water on the wind and clouds at this time, they will understand what it means to splash impermeable.

After about five minutes, Fengyun retracted his sword and stood, and he had finished practicing his sword technique.

Although he has put a lot of effort into knife techniques over the years, the number of knife moves he has created is not very large, because he understands that the knife is a killing weapon, and it does not need too many moves, and many times a knife can decide the winner or even life and death.

There are too many knife moves, especially the bells and whistles, which are not only not conducive to improving the level of knife skills, but will leave a lot of flaws.

Therefore, many of these knife moves in Fengyun drills are still created to fit the environment, otherwise there will be fewer of them.

After practicing the sword moves, Fengyun's brows furrowed.

He found a problem, a very important one.

Although the knife he was using now was much better than the knife he had used before in every way, there was always a certain separation between it and him, which prevented him from achieving the state of unity between man and knife.

This is absolutely unacceptable to him, because if he can't achieve the state of human and knife integration, his sword skill level will not be able to be fully displayed, which will greatly reduce his combat effectiveness, and it will not even be as good as when he uses a bone knife.

Fengyun looked at the knife in his hand and showed a thoughtful expression, obviously confirming what the problem was.

After about ten minutes, Fengyun suddenly grasped the blade, and then pulled it, and blood gushed out, staining the blade bright red.
