The reason why Xu Hai was so urgent was because he knew that he was running out of time before the curse attacked.

Fortunately, Ye Hanshuang only sent people to monitor the movements of the Xu family's cottage before, and did not startle the snake.

And Ye Hanshuang's spies told her that there was no movement in the Xu family's cottage, and everything was the same as before.

After knowing the news, Xu Hai guessed that Xu Yifan was very likely to be in retreat.

He had already entered the Ten Thousand Laws Linglong Pagoda and took out the Iron Sea that he could only take out if he had cultivated to break through to the early stage of Ning Dan

In the iron box, there is a set of Kunpeng martial arts "Kunpeng Battle", "Blood Refining Secret Method", ten bottles of Ning Dan Xian Dan and ten bottles of Shen Yi Xian Dan.

After his cultivation broke through to the early stage of the Ning Dan, he would not be able to take the Fusion Xian Dan and the Expanding God Pill.

From now on, he will take Ning Dan Xian Dan and Shen Yi Xian Dan.

On the way, he concentrated on studying the set of martial arts of "Kunpeng Battle", and he found that once he burst out the full power of this set of martial arts, he could increase his combat power to about three times that of his peak moment in the early stage of Ning Dan in a very short period of time.

At the same time, he could use the power of Kunpeng to double his combat power, and he judged that as long as he cast the Kunpeng Battle, then he could burst out in a very short period of time, and his combat power was comparable to six times that of him at the peak of this realm, which was a very terrifying explosion of combat power.

Of course, if he wants to perform this trick, he needs to consume a lot of Yuan Power.

Moreover, the Kunpeng battle belonged to a boxing technique, so he had no way to use the fourth-order spirit sword Wind Thunder Sword, which made him feel embarrassed.

"I don't know what I should choose? I should have chosen the fourth-order gloves in the first place!"

Xu Hai sighed in his heart, but he knew that the reason why he chose the fourth-order spirit weapon Wind Thunder Sword at that time was because he felt that it was the most suitable for him to use.

Moreover, at that time, his cultivation had not yet broken through to the early stage of Ning Dan, and he didn't know that when his cultivation broke through to the early stage of Ning Dan, he could get a more powerful set of Kunpeng martial arts in the Ten Thousand Laws Linglong Pagoda.

He set his eyes on the Blood Refining Secret Method, and after he studied it, his brows furrowed.

He pondered for a long time, and finally decided to refine the fourth-order spirit sword Wind Thunder Sword by blood.

The reason why he had some scruples was because once he cast the Blood Refining Secret Method, he could be the same as the Wind Thunder Sword Heart.

From then on, the Wind and Thunder Sword was like his hands and feet, completely obeying his arrangement.

If he wants to make the Wind Thunder Sword in the future, he doesn't need to consume too much spiritual power.

But once he used the Blood Refining Method, the consequences would be very serious.

Because the Wind Thunder Sword has a part of his essence blood on it, once the Wind Thunder Sword is damaged, then his divine soul will be damaged.

If the Wind Thunder Sword is completely destroyed by the enemy, then he will be severely damaged by the Divine Soul.

He pondered that now that he still had some time, he should take the risk and refine the Wind Thunder Sword with blood.

"If I can't kill Xu Yifan, Peony and Wang Lili, then the curse of my body will attack!

He knew that if he couldn't kill the three of them before the curse hit, he'd have to be killed by the curse that went on.

Moreover, those three rao really deserve to die.

Therefore, he decided to refine the Wind Thunder Sword with blood.

Less than three hours later, they approached the Xu family's cottage, and they decided to find out the situation inside before they acted.

The three killer soldiers split up in two ways to find out the information inside.

Xu Hai was with Ye Hanshuang, and he took advantage of this time to carry out blood refining.

He first drew on a piece of rune paper the magic circle needed for the secret method of blood refining.

The first time he drew this kind of circle, he had to practice first.

After practicing more than 30 times and wasting more than 30 pieces of rune paper, he finally succeeded in drawing one.

Then, he wanted to cut the tip of his sword through the middle finger of his left hand, squeezing out more than a dozen drops of blood from it, and he smeared his own blood evenly on the rune paper.

He took a deep breath and operated the Yuan Force according to the operation method of the Blood Refining Secret Method.

After a while, the blood on the rune paper began to merge with the rune paper.

Just after the blood was completely fused with the rune paper, he placed the Wind Thunder Sword on the rune paper.

As soon as his mind moved, the rune paper quickly wrapped the Wind Thunder Sword completely under his mental envoy.

The next moment, flames erupted from the rune paper, and it quickly burst into flames.

Although it burned, the blood that had been fused with the rune paper formed a strange mark in the air.

After Xu Hai saw the mark appear, he took a deep breath, and he hurriedly ran the exercise method and smashed the mark into the Wind Thunder Sword Zheng

At first, there was no reaction from the Wind Thunder Sword.

But after a while, the Wind Thunder Sword began to tremble, and it also made a buzzing sound from time to time.

When Xu Hai saw the current appearance of the Wind Thunder Sword, he knew that he had completed most of the steps.

After a while, he saw that the Wind and Thunder Sword was trembling even more violently, and he immediately continued to squeeze out more than ten drops of blood from the middle finger of his left hand, and then evenly smeared the blood on the sword's body.

As soon as his mind moved, the blood quickly penetrated into the sword body Zheng at a speed visible to the naked eye

After a while, the Wind Thunder Sword became a little more stable.

But the good times didn't last long, and it didn't take long for the Wind Thunder Sword to continue to tremble violently, Xu Hai drew a gourd in the same way, cut the middle finger of his left hand, and then evenly smeared his own blood on the sword, and then ran the exercises, so that his blood and the Wind Thunder Sword fused together.

This process lasted more than ten times, and after two hours, the Wind Thunder Sword completely stabilized.

Xu Hai exhaled a turbid breath, he knew that he had succeeded.

As soon as his mind moved, the Wind and Thunder Sword flew out of the ground under his envoy and flew into his palm Zheng

He had only released a small amount of Yuan Force just now, and the Wind and Thunder Sword had already automatically flown into his palm.

He hurriedly held the Wind and Thunder Sword, and went outside to perform the Cloud and Flowing Water Sword Technique.

After a while, he found that some of the movements in the Flowing Cloud Sword Technique that he couldn't do before, he had now done it.

He only now discovered that he had already connected with the Wind and Thunder Sword, and as a result, he was able to increase the power of the Flowing Cloud Sword Technique by two to three percent.

Moreover, the Wind Thunder Sword is extremely fast, and he can even use the Wind Thunder Sword as a sharp weapon for sneak attacks, destroying the other party without knowing it.

Ye Hanshuang nearby had been secretly observing Xu Hai, and when she saw that Xu Hai had refined the fourth-order spirit sword Wind Thunder Sword, her eyes widened and she was dumbfounded.

"This refining technique of his is like the refining technique of some evil sect, what is the name of this refining technique?"

Her eyebrows furrowed, she was thinking about what kind of refining technique Xu Hai had revealed just now.

But she thought about it for a while, but she didn't have any impression.

"Xu Hai, have you practiced well?"

Ye Hanshuang asked tentatively.
