Xiang Tian was originally a little suspicious of the spar, but seeing that the stele spirit was generously admitted, he didn't say anything more.

"But let me tell you first, because you didn't leave anything behind after hunting ghosts this time, so the town boundary monument didn't help you convert any items. It's gratifying, that is, a slight increase in divine thoughts. The stele spirit seemed to think of something, and his tone changed.

When Xiang Tian heard this, his face looked calm and abnormal, but a trace of excitement flashed in his eyes.

Although after he usually kills the demon beasts, the town boundary monument can transform the useful parts of his corpse into things suitable for his cultivation, but those things are only auxiliary items after all, and Xiang Tian already has a lot of them in his hands, so he won't care too much.

And this time to hunt ghosts, judging from the results, Xiang Tian certainly did not get those auxiliary pills, spirit grass seeds. However, his divine thoughts are permanently growing, and compared to those auxiliary things, the growth of his own strength is really beneficial. And yesterday's increase in divine thoughts was enough to be worth Xiang Tian's two years of divine thought penance.

"Okay, I'll recover my body first, after this action, the loss of mind is huge, and the essence and blood are also a little short, if you don't use the elixir refined in the town boundary monument, I'm afraid tonight's action will have to be canceled." Feeling his sluggish qi and blood and slightly sluggish mana, Xiang Tian made a judgment without thinking.

"Yes, although you have a lot of pills now, but you are inevitably a little tired physically and mentally when you move repeatedly. It's better to rest tonight, and by the way, inhale this black big knife into your body to nourish it, and then act tomorrow night. The stele spirit also muttered for a while, and then said.

......

Four months later, the deacon hall of the Imperial Soul Sect.

"Xiang Tian, you kid is really amazing! It's been half a year since you left, if I didn't know that your kid is clever, I would have thought you were eaten by those demon beasts!" Ye Lun looked at the black-robed young man in front of him, and couldn't help but say with a little joy.

"Uncle Ye is serious, I am also looking for a chance to sharpen outside, so I have been missing for a while. No, I also brought some mission items from the sect. As soon as Xiang Tian finished speaking, he took out the storage bag on his body and pushed it forward.

It has been almost a year since he came to this cultivation realm, and now Xiang Tian is a little more stable and less immature than when he first came. I'm afraid that even Xiang Tian didn't notice that with his tempering in this world, his temperament is constantly changing.

"Oh, it seems that you have gained a lot in the past six months. "How can the aura on Xiang Tian's body be hidden from this Deacon Ye, although the former was hunting ghosts during this time, the faint evil aura remaining on his body was revealed.

"It's okay, I also broke through the fifth layer of Qi training in a life-and-death struggle, and I rushed back. Otherwise, with the monthly payments of the sect, I am afraid that it will not make a difference in this small comparison. Xiang Tian's expression darkened, and he said slightly depressed.

"Don't worry, now those little cubs are not very high in cultivation. I haven't seen a disciple in person, but an outer disciple like you, just in terms of your Nether Cave, I'm afraid that the peak of the third layer of Qi cultivation is the limit. Impeller didn't expect that Xiang Tian's current depression was actually pretended, and he immediately comforted.

"The peak of the third layer of Qi cultivation, haven't you broken through the fourth layer?" This time, Xiang Tian was genuinely surprised, remembering that when he was hunting ghosts and ghosts, he had already broken through the shackles of the third layer and reached the early stage of the fourth layer. But he didn't expect that now that he had come back with a fifth-level cultivation, no one among the other disciples would surpass him.

"No, they don't spend every mission like you, in a life-and-death struggle, so that they constantly push their limits. Therefore, the third layer of Qi cultivation is already good for them. Ye Chakra shrugged his shoulders, and his words were inevitably a little disappointed with the outer disciple.

"Hehe, everyone has their own ambitions, after all, there is only one life, they are still young now, of course they don't want to joke with their lives for no reason. Xiang Tian nodded in understanding, and the tension in his heart was eased.

"Then you are still working so hard? To be honest, in fact, I didn't expect much from you, and I was just looking for a successor at first. But your performance is so amazing that I can't help but feel a hint of admiration for you. The impeller didn't have much scruples about Xiang Tian, so he said what he thought in his heart.

"Uncle Ye is serious, what we and other monks are trying to do is just fighting for that faint trace of immortality. And I'm just one of those beings. "After all, he was a highly educated person before, and even the monks in this world may not be able to theorize him, so Xiang Tian's view of things is much more thorough than that of ordinary people.

"Well, if the monks of the Imperial Soul Sect had this idea from you, then my Imperial Soul Sect would have monopolized the Eastern Regions long ago. Okay, I'd better take a look at what you brought first. Seeing that Xiang Tian was so sophisticated, Ye Lun originally wanted to teach him the experience, but he didn't need to say more

"These are ......" The impeller picked up Xiang Tian's storage bag, swept his consciousness roughly, and immediately let out a light "huh".

"Hehe, a total of two hundred demonic stones, enough to deal with my contribution to the sect in the past six months. Xiang Tian grinned and squinted at the impeller.

"Although the quality of these demonic stones is not high, it is superior to the sheer number of them. Xiang Tian, what do you want to change?" For what Xiang Tian took out, the impeller was also a little surprised. It seems that Xiang Tian's days have not been in vain!

"Hyakkiba. ”

......

Out of the deacon's hall, Xiang Tian quietly returned to the cave of the Netherworld.

Seeing that Xiaobi was still more than a month away, Xiang Tian never went out in the next ten days, except for a trip to Zongmenfang City to find Luo Yi once.

And Xiang Tian has been staying in the cave for more than ten days, recuperating his strength, refining the Hundred Ghost Flags, and making final preparations to unlock the next seal of the black big knife.

Hyakkiba, as the name suggests, is a flag that holds hundreds of ghosts. Generally, ghost flags are judged by the number and quality of ghosts they contain.

If it is a low-grade magic weapon-level ghost flag, it can hold more than a dozen ghosts at most, and the effect is also very limited in terms of single summoning. If it is a mid-grade flag, then the number of ghosts it can accommodate is nearly a hundred.

And the high-grade one, that is, the hundred ghost flags that Xiang Tian exchanged this time, this flag can hold hundreds of ghost things, once it is sacrificed, just saying the sound of this ghost roar can frighten some monks who are in an unstable mood. Xiang Tian exchanged it this time, but it was another killer feature.

I saw that Xiang Tian silenced his divine consciousness in the town boundary monument, and immediately pulled out an ordinary ghost thing from it, and it took half an hour to refine it into the hundred ghost flags. Subsequently, Xiang Tian concocted more than a dozen ordinary ghost things, as well as a ghost thing with a level of qi cultivation, and then he stopped.

One of the functions of the Hundred Ghost Banners is that as long as the power of the ghosts in the banners is stronger than the power of the ghosts that are refined, and there is enough time, those ghosts will be automatically refined by them. Xiang Tian also took the initiative to refine more than a dozen of them first, and the rest could let the Hundred Ghost Banners run automatically, and Xiang Tian only needed to convey mana from time to time.

After tidying up the hundred ghost flags, Xiang Tian set his eyes on the original black big knife.

However, at this time, the appearance of the whole knife has changed dramatically. Today's broadsword is still a six-foot giant blade, but the black on its blade has all faded and turned into pure silver white. And the ordinary hilt of the knife has also been replaced by a blood-red color at this time, and at the tail of the hilt, a pair of blurred beast heads appeared.

......

A month ago.

"Xiang Tian, do you have any plans for this knife now?"

"Of course, it's to unlock the next seal!" Xiang Tian said with a slightly strange look at the stele.

"No, I mean, you'd better put this matter aside for a while and wait until you return to the sect before unsealing it. At this time, the face of the stele spirit revealed a trace of solemnity that did not match his appearance and age.

"Can I know why?" Xiang Tian knew that the stele spirit would not be untargeted, and immediately asked.

"It's very simple, after the previous efforts, now this knife has turned from black to blood red, and the current seal, only the blurred beast head at the end of the handle has not been revealed. For these seals, once they are unsealed, the aura of their breaking will spread. For this, the current town boundary monument has no power to blockade. ”

"The top priority is to return to the sect and exchange it for a hundred ghost flags. As long as the Hundred Ghost Banner is successfully refined, then when you unlock the seal of this big sword, the ghost qi fluctuations emitted by it will automatically be absorbed by the Hundred Ghost Banner and nourish the Hundred Ghosts. If you really show a trace of fluctuation, you can explain it, and say that you are refining the Hundred Ghost Banners. ”

"Anyway, this knife is the same ghost artifact as the Hundred Ghost Flags, so it won't arouse suspicion. Another point, there are too many high-level ghosts you have captured on this trip, and if you take them out, it will easily expose your strength. Now it's better to absorb all of them by this knife, and refine the rest in the Hundred Ghost Banners, which can help increase your divine thoughts, second, refine a Hundred Ghost Banners that suit your current strength, and third, unlock this layer of seals with more confidence. ”

"With these three points, I think you know what to do. The stele spirit was not as impatient as before, but instead elaborated on the benefits and stakes and said to Xiang Tian.

It was precisely because of the conversation that Xiang Tian extended the time to unseal the big knife.

......

Ten days later.

"There are two third-layer ghost things, five second-layer ghost things, seventeen first-layer ghost things, and the rest are all imps who don't enter the stream, and finally all of them are sacrificed into this hundred ghost flags. Xiang Tian watched the Hundred Ghost Banner refine the ghost things he had captured for more than four months into the Hundred Ghost Banner, and his heart couldn't help but twitch.
