Li Yi was surprised and delighted, seeing that this Shura blood crystal was not packed with anything, and there was even a layer of dust on it, he said in his heart: "It seems that the Bi family also got this Shura blood crystal by accident, and they didn't really recognize it, I don't know how precious this thing is!"

With the Shura Blood Crystal, Li Yi put aside the Heart Cloud Stone, Void Meteorite, and Xuanying Cold Ice, determined to use the Shura Blood Crystal to improve Xu Longzi's physical strength.

That Shura blood crystal was only the size of a fist, but when it was held in his hand, he could feel the ferocious killing intent contained in it even more, and even the palm of his hand was filled with sharp pain, as if it was about to be torn apart.

A true qi came out of Li Yi's fingertips, condensed into the shape of a small sword, and cut it towards the Shura blood crystal, but who knew that he couldn't cut it.

You must know that his true qi is fused with the Heavenly Flame and the Infinite Divine Water, which is extremely powerful, and ordinary materials can be cut at once, but there is not even a trace on the Shura Blood Crystal.

"It seems that this Shura Blood Crystal is even harder than I imagined!" Li Yi thought as he urged the Shadow Demon Divine Power, and the shadow turned into nineteen shadow swords, and then the nineteen swords merged into one and slashed towards the Shura Blood Crystal.

I saw that there was a little more dent on the Shura blood crystal, and it was still not cut.

However, it was already very good to be able to cut, Li Yi was patient, and kept cutting at the dent, and it took more than half an hour to finally cut off a small piece of Shura blood crystal.

A monstrous killing intent erupted in an instant, soaring into the sky, and even the white clouds were dyed red with killing intent.

Li Yi was secretly frightened, and let Xu Longzi swallow the small piece of Shura blood crystal, and the rest of the Shura blood crystal was immediately put back into the storage bag, so as not to cause too much movement and cause unnecessary trouble.

Xu Longzi's body shook, and the Shura blood crystal slowly dissolved in his body, and the murderous aura was vertical and horizontal, making a loud sound like a drum, knock knock, the murderous aura in the Shura blood crystal was too strong, even if Xu Longzi's body was extremely strong, it was also a little difficult to support, and it was impossible to refine it in a short time.

Li Yi could only inject a stream of true qi into Xu Longzi's body to help him speed up the refining speed a little, but other than that, there was nothing he could do.

"It's up to him to make it. Li Yi thought secretly.

When Xu Longzi was desperately entangled with the Shura Blood Crystal, Li Yi was not idle, but began to study the Shura Array.

The Shura Circle is a fourth-level Circle, which is extremely complex and profound!

Li Yi had studied it roughly, but he didn't have much experience, and now that he has the Shura Blood Crystal, then this Shura Array must be studied thoroughly, otherwise it will be a waste of such a treasure as the Shura Blood Crystal.

Once he studied it thoroughly, and Xu Longzi withstood the impact of the Shura Blood Crystal and completely refined it, then Li Yi could refine this corpse demon into the legendary Shura.

Compared to the corpse demon, Shura is obviously much more powerful.

And the growth of the corpse demon is relatively slow, but Shura is different, Shura can improve his strength by killing, and the growth rate is far faster than that of the corpse demon, which is simply born for killing.

Li Yi meditated on the Shura Array, and before he knew it, the sky was getting dark, the moon and stars were sparse, and the wind was warm in all directions, and there was an indescribable comfort.

But Li Yi had no intention of enjoying it, with a sad face.

He hadn't even mastered the third-level magic circle thoroughly, and the Shura magic circle was a fourth-level magic circle after all, which contained Yang Xiaohua's life's work, where was it so easy to study thoroughly?

The fourth-level magic circle is not only the outline of the runes, but also the rules of operation are very different from the third-level magic circle, and the running lines are more complex and the requirements are more precise.

For example, which rune starts to run first, and from which direction, and how to choose the timing and speed of operation, so as not to cause conflicts between runes and collapse the magic circle, are all very particular.

Li Yi didn't study it, and as soon as he studied it, he suddenly felt dizzy and his eyes were full of gold.

At this time, he suddenly heard a slight footstep behind him, and when he looked back, it was Sun Yue'er, and he couldn't help but be stunned, and asked, "Miss Yue'er, how is my senior sister now?"

Sun Yue'er said: "She will be fine for the time being, I have tried my best to help her save the last trace of life, but it is difficult to say how long it can be delayed." ”

Li Yi frowned and said, "Thank you, Miss Yue'er, it seems that I have to win that map of the South China Sea Continent as soon as possible!"

"Just call me Yue'er. Sun Yue'er said softly, "You saved us, I should help you with this little favor, don't thank me." ”

Li Yi was silent.

Xu Longzi on the side suddenly trembled violently, and the deck shook.

Sun Yue'er was startled and said in horror: "He...... What's wrong with him?"

Li Yi said: "It's okay, he's refining something, and it's okay to get through." ”

"What if you can't make it?" Sun Yue'er asked.

Li Yi said: "Then the bamboo basket will be empty, and it will waste energy in vain, and this corpse demon will be useless!"

Sun Yue'er stared at Xu Longzi's face for a while, with a hint of sympathy in her eyes.

Li Yi saw it clearly, slightly surprised, and asked, "Do you think it's wrong for me to do this?"

Sun Yue'er shook her head and said, "No, I just think, why did he have to kill us, and finally let himself end up like this, what is it worth?"

Li Yi sighed: "I also want to know. In fact, if I had a choice, I wouldn't want to refine him into a corpse demon, but I had no choice but to fight evil with evil!"

The words fell, and a hearty voice came from the cabin: "What a fight against evil with evil!"

But it was Tang Jing who strode out.

"I said big night, you two muttered, what are you whispering?" Tang Jing said with a smile.

Sun Yue'er smiled: "I stayed in the room so stuffy, come out to breathe." Your Highness, do you see that the moon is big and round tonight, isn't it beautiful?"

Tang Jing pursed his lips and said, "What's this, it's not the blue moon coming, where is there anything that is not beautiful, it's not all the same!"

"Blue Moon Coming?" Li Yi said curiously, "What's that?"

Sun Yue'er blurted out: "That's ......"

"It's nothing!" Tang Jing interrupted Sun Yue'er's words in time, "Brother Li, this involves the secrets of my Blue Moon Country, and it is not enough for outsiders, please forgive me!"

Li Yi nodded, and said in his heart: "It turns out that the name of Blue Moon Country also has a lot of origins!"

"You go in. Tang Jing said to Sun Yue'er.

Sun Yue'er sighed and went in a little reluctantly.

Tang Jing glanced at Li Yi and said with a strange expression: "Brother Li, let me ask you, what is the relationship between you and your senior sister?"

Li Yi was stunned, a little dazed in his heart, and said without thinking: "Naturally, it is the relationship between the senior sister and the junior brother, otherwise what else can it be?"

Tang Jing smiled: "Really? I can't see it, your senior sister is not the only one, why is she with her and not with others? Do you like her?"

Li Yi coughed, turned around, and said, "I'm going to cultivate now, Brother Tang, please go back!"

"Okay, okay, I won't talk about it, right?" Tang Jing waved his hand and said, "Even if you cultivate, I will also go in without breathing." ”

After a while, I heard Tang Jing speak again: "Although Yue'er's girl is still young, she still looks good, she is kind-hearted, and she has a high level of medical skills, Brother Li, what do you think of her?"

Li Yi said: "Xiao Qi, drive him away!"

Xiao Qi, who was standing silently on the side, walked towards Tang Jing, she was not even tall at Tang Jing's waist, she reached out and grabbed Tang Jing's calf and pulled it hard.

Tang Jing fell to the ground.

"Wait a minute, there's something to say!" Tang Jing shouted.

Xiao Qi couldn't understand his words, and dragged him straight to the cabin, and a shrill friction sound sounded on the floor.

Li Yi put his mind back on the Shura Circle.

Originally, he had already encountered a bottleneck and was upset when he comprehended this fourth-level magic circle, but after Tang Jing's trouble, he temporarily forgot about his troubles, and when he came to comprehend again, he actually had a feeling of sudden enlightenment.

In fact, this is also a situation that is often encountered in practice, when you reach a dead end, you will feel confused, confused, as if there is no way out, and it is difficult to think of getting out of the dead end and starting from scratch.

Tang Jing made a mistake and helped Li Yi find his direction again, once the bottleneck that had plagued him for a long time was thoroughly understood, it was basically a flat river later, and after two hours, he had comprehended all the Shura magic arrays and knew it in his chest.

At this time, Xu Longzi had already stopped trembling, and saw that under the moonlight, his skin gradually turned from dark gold to a faint scarlet, and his eyes also became scarlet, looking very hideous and terrifying.

A monstrous killing intent emanated from Xu Longzi's body.

Shura Blood Crystal, finally completely refined!

Li Yi was secretly happy, but he didn't rush to carve the Shura Array, but first carved several first-level magic circles such as the Tengyun Array and the Divine Power Array, and then began to depict the Shura Array at the center of Xu Longzi's eyebrows.

Every stroke is extremely careful, lest something go wrong.

This is the first time he has carved a fourth-level magic circle, especially the formation carved on the head of the corpse demon, to say that he is not nervous at all, it is impossible, he can only hold his breath and condense, maintaining a high degree of mental concentration.

The Shura Circle is extremely complicated, consisting of seven hundred and eighty-one runes, because it is carved on the head of the corpse demon, the runes must be engraved very small, which undoubtedly increases Li Yi's burden.

Although his refining skills are superb enough, he also feels very difficult.

The reason why he carved the Shura Circle on his head was because the corpse demon's skull was the hardest part of the body, and it was most likely to withstand the power of the Shura Circle.

Time passed little by little, and before I knew it, the moon was long gone, and at the junction of the sea and the sky, a white light lit up, then turned from white to red, and then shone purple.

The sun is rising.
