Shi Lingyao was stunned.

Xu Jingyan glanced at her, and then said honestly: "Don't look at it, I really don't know how to use it." ”

"Hehe, what a nerd, I'm curious where you got this sword bag. Xu Jingyan's answer made Shi Lingyao chuckle.

Xu Jing was silent.

"I don't think your cultivation is more than the second order of the cultivation period, the heart source of cultivation, there has not been a heart source master in the entire Xia Tang Kingdom for at least a hundred years, and you don't know how to use it with a good sword bag, so you won't be the descendant of the Su State Hidden Sword Pavilion, you should have obtained the inheritance of a certain great power, right?" Shi Ling Yao analyzed carefully.

Xu Jingyan was shocked, this teacher Ling Yao was really smart, and he was able to guess so much.

"Your wooden sword is also the result of that inheritance, right?"

Facing Shi Lingyao's question, Xu Jingyan nodded.

"That's right, some low-level sword sac sac sacrifice training methods are similar, but the high-level sword sac left by the big sect requires the source power condensed by the mantra and heart method of this sect to be sacrificed, your sword sac should belong to this category, as long as you practice the source technique inherited by the source master and cooperate with the sacrificial spirit decision, you can sacrifice this sword sac. ”

"Sacrifice, it turns out that you need to practice to open. After listening to Shi Ling Yao's words, Xu Jingyan was a little stunned, this sword bag is currently ownerless, no matter how he detects this sword bag, he has no reaction, it turns out that he has not practiced.

"You just saved me, I taught you to practice the mantra, and you don't owe each other. After Shi Lingyao finished speaking, her expression became a little cold again.

Xu Jingyan touched his nose and smiled bitterly: "It's better to change places, I'm afraid it's not safe here." ”

Shi Lingyao turned his head slightly to look at the bandaging on his right shoulder and nodded slightly.

The two took the breathless Hong'er sister to a stone cave three feet deep.

Shi Ling Yao taught Xu Jingyan the Sacrifice Spiritual Decision, and Xu Jingyan said sincerely: "Thank you"!

A quarter of an hour later, Xu Jingyan drew a sword rune on the black sword sac with blood according to what Shi Ling Yao taught, and then urged the sacrificial spirit decision, and transported the Zen Shadow Sword Duel, the heart source power of the Zen Shadow Sword Duel in his body was shocked, and a trace of the blood sword rune poured in, the Zen Shadow Sword trembled violently, and the black sword sac actually disappeared out of thin air and turned into a wisp of blood and suddenly shot into the Zen Shadow Sword, the faint light disappeared in a flash, and the Zen Shadow Sword also stopped trembling.

Holding the Zen Shadow Sword in his hand, a sense of blood connection came, and at this moment, it seemed that the Zen Shadow Sword was a part of his body, which was more intimate than when he fused the remnant power of the Zen Shadow Sword before.

The sword bag was completely integrated into the Zen Shadow Sword, and his mind penetrated, Xu Jingyan's heart was shocked, there were at least five zhang square in this sword bag, how many things had to be put in this space the size of a courtyard.

Under the reflection of the mind, in this space, there is a bronze scroll and a wooden plate, don't think that this is the formation map and array plate of the Nine Cold Cloud Phantom Array, there are many stones of different sizes and colors on its side, all of which are source stones ranging from the first to the third order, with various attributes, gold, wood, water, fire, and earth, and even some special attribute source stones derived from the wind system and thunder system derived from the five elements.

Xu Jingyan's mind swept by, outside of this space, he seemed to see something, but it was very vague, as if there was a similar hiding space outside this space.

"Fairy Yao, is there a second layer of storage for this sword bag?" Xu Jingyan asked unclear in his heart.

"Second floor, what do you see?" Shi Lingyao's tone seemed a little hurried.

Xu Jingyan didn't understand how Shi Lingyao could say what he saw in such a tone.

"Could it be a second-order sword sac, you can summon the sword sac and I'll take a look." Shi Lingyao opened his mouth, thinking that Xu Jingyan definitely didn't know how to summon the sword bag, so he taught him to summon the mantra and passed it on to him.

Xu Jingyan recited the mantra and shook the Zen Shadow Sword in his hand, and the black sword bag appeared in his hand.

Shi Lingyao hurriedly snatched the sword bag over and looked left and right, and let out an exclamation: "Idiot, this is actually a fourth-order sword bag, you are really lucky." ”

Xu Jingyan was stunned for a moment, what is a fourth-order sword sac? The sword sac is also divided into grades, how does Shi Ling Yao distinguish this as a fourth-order?

Xu Jingyan raised the question in his heart, and Shi Lingyao naturally explained it.

It turns out that this sword bag is divided into ten orders, to be precise, one to nine orders, before the first order, but only the size of eight feet is the most ordinary sword bag, and the sword bag on the first order needs to be really forged by the organs, and the materials used are all cinnabar silk, the use of this material with space power can make the first-order sword bag have a radius of five to seven fathoms, but cinnabar silk is also extremely rare, so this class of sword sac is also extremely valuable.

The sword sacs of the second order and above were all arranged by the formation master with a space formation, so their space could reach a range of five or six zhang or even several miles.

And Xu Jingyan's black sword bag is depicted with the formation engraved by the fourth-order sword bag.

Shi Ling Yao recognized this formation pattern at a glance, and in her master's hand there was a fourth-order sword bag engraved with the same pattern.

"You'd better not show this thing in front of people, otherwise your cultivation will inevitably lead to death. Shi Lingyao had some cautious advice.

Xu Jingyan nodded and looked at Shi Lingyao strangely: "Aren't you excited?"

Shi Lingyao was stunned for a moment, her face was cloudy, and she ignored it.

Xu Jingyan smiled slightly: "Are we friends?"

Shi Ling Yao smirked and said jokingly, "What's the matter, you want to be friends with me, a demon girl?"

Xu Jingyan shook his head: "Now all the cultivators in the world are material sources, and everyone in the world thinks that the Heart Source Master is a demon, so what qualifications do I have to dislike you if I am a Heart Source Master." ”

Shi Lingyao nodded with satisfaction: "It seems that you have figured it out, the Heart Source Master has been included in the discussion of those righteous paths, although you are only the strength of the second order of the Source Cultivation Period, but you are cultivating the power of the Heart Source, it is better to join my Centrifugal Sect, change to the Centrifugal Source in the future, with your talent, you may be able to become a true inheritance in a few years, you will be much safer with the protection of the master, and it is much stronger than you to explore and cultivate alone." ”

Xu Jingyan thought about it for a while, indeed, the path of the source of the heart is unguided and he doesn't know where to go, the centrifugal source comes from the source of the heart, and it is not a problem to repair it by himself.

Suddenly, my heart moved, what was the purpose of the mysterious man recasting the heart source body for himself? The power of the heart source is also his second rebirth, is he so undetermined now? Doesn't he still want to rely on the power of the heart source to find his parents?

Xu Jingyan shook his head: "Thank you, I've always been used to being alone, if I really can't mix it up one day, let's talk about it." ”

"Hmph, if you don't want it, you don't want to, my centrifugal sect still doesn't lack your disciples in the cultivation period. Shi Lingyao frowned and snorted coldly, thinking that Xu Jingyan looked down on the centrifugal faction, so he simply didn't go over it and didn't take care of it.

Xu Jingyan touched her nose and smiled bitterly, how could Shi Lingyao have the previous posture at this moment, she was clearly a normal girl.

With a flash of inspiration, Xu Jingyan suddenly thought of something, and looked at Shi Lingyao with a serious expression: "What is the source cultivation period you are talking about?"
