Fengyun looked at the blade stained red by his own blood, and unconsciously showed a nervous expression.

He did feel a little apprehensive right now, and he didn't know if he would be able to achieve the results he wanted by doing this.

He did this in order to break the barrier between him and the newly refined knife, so that he could reach the realm of human sword unity with it, and then let his sword skills be fully developed.

This is very important to him.

Although he has no shortage of attack methods, if you want to talk about lethality, they can't be compared with his knife skills, and there is still a huge gap between his other attack methods and his knife skills in terms of lethality, or even not at the same level at all.

If he can't complete the display of his sword skills, his combat power will be reduced by at least half, which is too serious.

Not to mention that the world he crossed over was originally unsafe, let's just say that in the current form, there are holes in the space wall, which makes the living environment more sinister, and if his combat effectiveness is greatly reduced, it will definitely be a very dangerous thing.

Not to mention that he is not alone now, there is an entire Golden Dragon Tribe that he needs to protect.

Therefore, when he found that there was a layer of separation between him and the newly refined knife, his heart couldn't help but sink sharply, feeling very disappointed.

His purpose in refining the new knife was originally to improve its combat effectiveness, but it turned out to be counterproductive, which he didn't want to see or accept.

However, he was not willing to give up the new knife.

Although there was a gap between him and the new knife, he could still tell whether it was good or bad, not only better than the knife he had used, but also better than all the weapons he had seen since he crossed into this world.

It would not be an exaggeration to say that his newly refined sword was a divine weapon.

It was precisely because his newly refined knife was so good that he didn't even think about giving it up, he found that there was a barrier between it and him, and the first thing he thought of was how to break this barrier.

But how to do this, he has no bottom in his heart, after all, this is the first time he has encountered this kind of thing.

In the end, it was what he had seen before the crossing that worked.

Although he also knew that the content was made up by the author, and it was not true, but this kind of thing happened to him through it, and what else was impossible.

Besides, he had already tasted the sweetness from these before, whether it was creating his own exercises, or inventing alchemy and alchemy, all of which were inseparable from the inspiration he had gained from them.

These successful precedents also confirmed that he used the method to break the barrier between him and Xindao.

According to the statement, there are many ways to deepen the connection with a new weapon, and in this method, the simplest and most operational is blood refining, and to put it in more detail, it is to establish a connection with the weapon through blood as a bridge.

Of course, other methods, Fengyun did not give up.

They were placed at the back of the ladder by Fengyun, and he would only use them after confirming that the blood refining was ineffective.

In other words, if the blood refining was successful, he wouldn't think about them anymore.

Not to mention that they are difficult to implement, you also need to pay attention to various taboos, and even if you fail, there is a possibility of backlash, so it is better not to touch them or try not to touch them.

Under Fengyun's apprehensive gaze, the blood on the blade began to flow, spreading from the blade part to the entire blade.

The blood lines were swimming on the blade as if they had life, and they were so fast that at first glance, unsuspecting people might think they were some thin snakes.

"There's a door!"

Seeing this scene, Fengyun's face couldn't help but show joy.

He thought about it, opened the palm of the hand that had been cut by the blade, looked at it, and found that under the effect of the powerful self-healing ability, the wound no longer bleed outward, and even the wound showed signs of convergence.

He glanced at the wound, then set his eyes on the blade of the new knife, and then gritted his teeth, and actually scratched the wound with his fingernails, causing it to bleed again, and deliberately urged the power of the totem to prevent the wound from healing.

In the blink of an eye, a pool of blood appeared in Fengyun's palm, plus his qi and blood were very vigorous, and the speed of bleeding was very fast, if he didn't take care of it, it would soon overflow from his palm.

Fengyun didn't let the blood go to waste, he poured them all on the blade, completely dyeing it red.

That wasn't all, he let his still bleeding palm grasp the hilt, and let his own blood stain the hilt too, no, soaked red.

In this way, the blood consumed by Fengyun is not much worse than a pound.

But he didn't care, as long as he could break the barrier between him and the new knife and make him donate more blood, he wouldn't frown.

Fengyun's approach worked, and as the blood stained the entire knife red, especially as the blood began to seep into the inside of the blade, he could clearly feel that some kind of connection had been established between him and the knife, and this connection continued to deepen.

At the same time, he could feel that the barrier between him and the knife was being broken, and in the end, it was completely gone.

After the blood penetrated into the blade, a large part of it was absorbed by the metallic aggregate, and after absorbing the blood, it was found that not only did it turn red, but it also looked very much like a blood vessel.

In fact, after absorbing blood, metallic aggregates not only look like blood vessels, but they also behave very similarly, shrinking and shrinking, as if there is blood flowing through them.

This state did not last, until the blood on the blade disappeared, and the metallic aggregate stopped moving, as if it had become the state that Fengyun had just refined again.

Only Fengyun knew that it was different, and that barrier between him and it had not only disappeared, but also allowed him to establish a very close connection with it.

He held the hilt of the knife and gave him the feeling that it had become a part of him, and that he was manipulating it as if he were manipulating his own fingers.

He couldn't help but swing the knife, cast his knife technique again, and then put the knife away and stand, and then he couldn't help laughing: "Good, good, good, great." Haha......"

After laughing for a long time, Fengyun stopped, but his face was still full of irrepressible smiles, and he seemed to be very happy now.

He was really happy, after passing the blood refining, the newly refined knife had made him completely satisfied, and he couldn't even find a flaw.

Don't say anything else, let's just say one thing, as long as he holds the new knife, he can enter the state of unity of human and knife anytime and anywhere.
