Yang Lin looked at the two bottles of blood in his hand, one bottle was purple and the other bottle was green, and shook his head with a smile, "This is the essence blood of refining the void-level transformation elixir, it's as simple as that" Yang Lin looked at the jade bottle in his hand and smiled bitterly again, " Hmph, it's not for the sake of my Lao Jiu's face, you must know that it is extremely difficult for the elixir to transform into a shape, let alone break through to the refining period, during this period, the effort they put in is dozens or even hundreds of times that of human monks, and the essence and blood of the elixir in the refining period are also very rare in the spirit world" Lao Jiu said triumphantly to Yang Lin about his exploits.

"But Lao Jiu, don't you only have a wisp of divine soul left, why are they afraid of you?" Yang Lin put two bottles of essence blood into the mountain and river fan and asked, "You know that I am just a wisp of divine soul, but they don't know, besides, my wisp of divine soul also has a bit of coercion in the previous life, with their strength, they naturally can't tell the truth from the false, they must treat me as a living immortal, even if the body is not here, they can descend to the mortal world through means to bring things like doppelgangers to the mortal world, that's why they are so respectful to me." After Lao Jiu finished speaking, Yang Lin nodded happily, if the boy and the giant turtle forcibly killed Yang Lin despite Lao Jiu's coercion, Lao Jiu would have no choice, fortunately, Lao Jiu bluffed them.

"The strength of refining the void, when the Demon Realm Holy Ancestor is out of trouble a hundred years later, why don't we just ask the boy and the giant turtle to take action?

"Are you stupid? Didn't you hear them say that they couldn't get out of this space? If you force them out, you will only die, then the Demon Realm Holy Ancestor should also be trapped in a space similar to this, and you can't descend your true body to the mortal world, then the Demon Realm Holy Ancestor should be sitting in the base camp by himself, and then send his subordinates to disturb the world" Lao Jiu reprimanded Yang Lin, but Yang Lin was inexplicably relieved after knowing that the Demon Realm Holy Ancestor himself could not come out to the mortal world.

"They are all inseparable from their respective spaces, so can we build a teleportation array between these two spaces?" in that case" Yang Lin suddenly thought of a brilliant idea, Lao Jiu pondered for a few breaths, and then said. Well, yes, but the teleportation array that needs to be established to connect two different spaces is very complicated, and the spirit stones required for a teleportation are also an astronomical amount, if you really have this kind of thought, you have to find a formation master to help you, and you can't study the formation by yourself in a hundred years" Lao Jiu affirmed the possibility of Yang Lin's idea, but Yang Lin was silent," Once I ask someone to set up a teleportation array, it means that I can enter and leave freely, and the secret here cannot be kept, and it is not certain whether those two elixirs will help" Yang Lin pondered for a while and stopped thinking about this problem, there must be a way before the car reaches the mountain. Now Yang Lin still had to focus his attention on the tower in front of him.

"I don't want to, let's talk about it in the advanced tower, there is all the inheritance of a spiritual sect there." Yang Lin glanced at the tower greedily and then raised his feet and walked towards the tower, the giant turtle and the boy had already told Yang Lin that the third underground floor of the tower was not allowed to enter, where the demon captured by the Northern Regions Little Sword Pavilion was imprisoned, even if ten thousand years had passed, the demon had died, but there were some mechanisms underground to prevent the demon from escaping, and the ban was still running, and the demon qi where the demon head died, the resentment was extremely heavy, and ordinary monks would be corroded if they entered, and it was possible to fall, and there was a merger period among those dead demons。

You can't go underground, there is naturally no problem on the ground, the scripture pavilion, arsenal, and material library of the Little Sword Pavilion in the Northern Regions are all on top of the tower, and the cultivation places of those elders are also mostly in the tower.

"Squeak" Yang Lin walked to the gate of the tower, which was dozens of feet high, and gently pushed it, the gate opened, and a rotten breath came to his face, Yang Lin hurriedly summoned a spiritual energy cover to protect himself, who knows if these breaths are harmful. "It seems that some materials can't withstand the erosion of time and have been broken" Yang Lin waited for two pillars of incense before entering the first floor of the tower, but the rotten breath still kept drilling into Yang Lin's nostrils.

Looking at the huge space in front of him, Yang Lin didn't even see the edge of the tower for a while. "Come out" Yang Lin touched the spirit beast bag, and the treasure hunting mouse was called out of the spirit beast bag by him, as for the little fox Yang Lin did not call it out, because once he encountered any danger, he could instantly put the treasure hunting mouse into the spirit beast bag.

"Look for it, don't leave any treasure behind" Yang Lin said to the treasure hunting mouse, the treasure hunting mouse said that he understood and began to run forward, in this tower, the treasure hunting mouse smelled too much treasure, which made it very excited.

The treasure hunting rat did not stay on the first floor of the tower, and went straight to the second floor, the treasures in the first floor have been taken away by other monks who came in for ten thousand years, and now the first floor of the tower is enough to starve the rats, the second floor of the treasure hunting rat did not stay, and the third-layer treasure hunting rat did not stay, until the fifth floor, the treasure hunting rat dragged out a dirty futon from a pile of dust.

"It turned out to be made from the grass heart of the thousand-year-old requiem grass, which is much better than the one I used, but it's a pity that the age is too old, and the effect of the requiem grass has almost dissipated a lot" Yang Lin checked the futon and put it into the storage bag, and then the treasure hunt rat ran up again, until it reached the seventh floor, the treasure hunt rat jumped on a candlestick, bit off the candle that was burned only a little bit, and took it into Yang Lin's palm.

"At this time?" Yang Lin looked at the small tattered candle, and he couldn't recognize what it was, "This is a candle refined with the grease of the golden whale, after being lit, it can dispel evil things, and it can also calm the soul, it is something that many great powers have to light when they cultivate, as for you, you can light it when you break through" Lao Jiu explained to Yang Lin, and Yang Lin seemed to have to put this candle into the storage bag.

The treasure hunt rat continued to run, and it has to be said that the things in this tower have been almost moved by the monks who have come in one after another within tens of thousands of years, and only a spirit beast with treasure hunting ability like the treasure hunt rat can find these treasures that have been forgotten in the corner.

One arrived on the tenth floor, and the treasure hunting mouse only found something that was not very useful, Yang Lin was a little disappointed, and the thing that surprised Yang Lin the most was that Yang Lin had no way to go in front of him after he reached the tenth floor, it seemed that the tenth floor was the top floor of the tower, but Yang Lin guessed that the tower was at least a hundred stories high.

"What's going on?" Yang Lin asked Lao Jiu a little anxiously, "It's just a combination of the space technique and the teleportation array, you go to the center of this layer to see if there is a huge teleportation array?" After Lao Jiu finished speaking, Yang Lin quickly ran towards the center of the tenth layer, and after a few breaths, Yang Lin waved his hand and a wave of spiritual power blew away the dust on the ground, revealing a very complex huge teleportation array.

"This is the case with the big sects, the disciples can teleport to their respective caves through their jade plates, and when they go to the Hidden Scripture Pavilion or the Hall of Merit or something like that, they can also arrive immediately through a similar teleportation array, which saves a lot of time," Lao Jiu explained to Yang Lin.

"But I don't have a jade plate at all, how can I teleport, then I won't be able to enter the space above the tenth floor forever?" Yang Lin was a little frustrated when he heard this, it seemed that he had no connection with the things in the tower, "Didn't you get a storage bag on that skeleton? There should be an identity jade plate in it" As soon as Lao Jiu said this, Yang Lin's eyes instantly lit up, "That's right" Yang Lin hurriedly took out the storage bag he obtained, opened it and searched carefully and found a purple jade plate, the age is too long, this jade card has become dim, Yang Lin originally thought it was a useless tattered thing, but now this jade card was carefully held by Yang Lin in the palm of his hand.

"It turned out to be the head jade card, it seems that person should be the last monk of the small sword pavilion in the Northern Regions" Lao Jiu muttered, "At this time, the head jade card?" Yang Lin asked in surprise. "Yes, you can use this jade card to enter any cave mansion or palace you want to enter" After Lao Jiu said this, Yang Lin was so excited that he couldn't help himself, this tattered jade card is now in Yang Lin's eyes.

"Okay, don't be happy yet, I don't know if this formation can be used" Lao Jiu's words made Yang Lin take a beating, "You must be able to use it" Yang Lin prayed and placed a few spirit stones in a few small holes according to Lao Jiu's instructions, and then Yang Lin quickly picked up the treasure hunting mouse, and then Yang Lin chose an area in the formation and then disappeared in place in a white light.
