"Haha, that's great, it's really still usable" Yang Lin was extremely excited after being teleported, because this meant that he could freely enter and leave any place in the Little Sword Pavilion in the Northern Regions with the purple jade card in his hand, and all the remaining treasures were in Yang Lin's bag, how could Yang Lin not be excited when he thought of this?

With a flash of white light, Yang Lin appeared on a large road, looking at the surrounding rooms, Yang Lin thought at a moment that he had come to a certain city in the mortal world, "These houses are not monks' caves, right?" Yang Lin looked at the rows of houses in front of him and said, the next discovery confirmed Yang Lin's guess, the doors of these houses are engraved with numbers one by one, maybe it is the reason why there are no monks who have come here to turn over after the wind and sun, these houses look very new, at least Yang Lin does not smell the smell of decay.

"Let's go in first" Yang Lin held the jade card and hugged the treasure hunting mouse, summoned an aura cover to cover himself and walked towards the first room, the reason why Yang Lin summoned the aura cover was that he was worried about what kind of mechanism these monks would put in his cave, and sure enough, the head token was indeed powerful, the purple jade card waved on the door of the house, and the room slowly opened, Yang Lin smelled the smell of decay again, presumably something in the room was broken.

Yang Lin summoned a flame in his right hand for lighting and walked into the room, after entering the room, Yang Lin found that the space of this room was extremely large, the size of the Luoxi Sect Hall of Merit, and the room was divided into several small rooms, the alchemy room, the spirit beast room, the spirit grass room, etc., this house must have used the technique of space, otherwise it would be impossible for the internal space to be so large and look small from the outside.

The treasure hunt rat was very quiet in Yang Lin's arms, Yang Lin sighed after discovering this, the treasure hunt rat was quiet, which means that there is basically no treasure here, and sure enough, Yang Lin turned the first house around, and finally found a dry bone in a corner, presumably this is the previous owner of this house.

The clothes on the dry bones have also weathered off, and they can't see their original appearance at all, and the dry bones are also scattered all over the ground, only a flat storage bag fell next to the dry bones, Yang Lin took a few steps and picked up the storage bag to open it to see that there was nothing in it except for a white jade plate.

"Hey" Yang Lin sighed and walked out of the room, and then came to the second room, a day later, Yang Lin had searched all the thousands of rooms on this floor, and the result was that he saw a lot of dry bones, and he also got a lot of storage bags, but he only found a few useful things, and these things are also very ordinary things, with limited effect, "It seems that most of the disciples who live in this layer are very low strength, and their strength may not even be as good as mine." Yang Lin pondered for a while and walked to the large array that he had teleported from, and after stuffing a few spirit stones, a burst of white light flashed, and Yang Lin returned to the teleportation array on the tenth floor.

"I should have gone to the eleventh floor, and I will go to the twelfth floor below." After Yang Lin finished speaking, he threw out a few spirit stones, and with a burst of white light Yang Lin came to the twelfth layer of the tower, the appearance of the twelfth layer looked no different from the eleventh layer, and after some searching, Yang Lin's harvest was also very few, in those days when there was no trace of spiritual energy, the monks used all the things in their hands that could extract spiritual energy, spirit stones, spiritual medicines, and even some items with spiritual energy were slowly consumed, so the things left in the small sword pavilion in the Northern Regions were definitely not much.

A month has passed. Yang Lin had already searched the first fifty layers of the tower, but the harvest was far inferior to Yang Lin's harvest in the Immortal Ding Palace, and he didn't find a single thing like the elixir seeds, "Didn't these monks even let go of their own natal magic weapons? Why haven't they even found a few magic weapons that can be seen?" Yang Lin said with a frown as he teleported back to the teleportation array on the tenth floor.

In fact, Yang Lin really guessed correctly, the monks will really use their natal magic weapon when they are useless, and the natal magic weapon can be practiced in the sacrifice, but the monk's life is only one.

"No matter, continue to look for it, judging from the bones seen these two times, most of the people living in the fifty floors are already Yuanying monks, and the seventy floors and above should be the residence of the god monks, and there should be some good things there" Yang Lin picked up the treasure hunting mouse and then teleported to the fifty-first layer, after some searching, this time Yang Lin finally did not return empty-handed, in a storage bag Yang Lin got a few spells and a book called "Mingxin Sword Codex" Yang Lin has never been very interested in things like exercises and spells, but there has been no other gain for a long time Yang Lin finally couldn't help but look at the spells with curiosity, and something unexpected happened to Yang Lin, the book that recorded the spell was accidentally sanded by Yang Lin's light touch, and in the cultivation world, in order to ensure that the spell is recorded, the books such as the exercises are not easy to be damaged, and the books are generally made of very special paper, and some secret arts and the like even use the skin of demon beasts to record, in order to ensure that they can be protected for tens of millions of years.

But this book was touched by Yang Lin but turned into sand, Yang Lin was shocked, and then touched other books as well, and then Yang Lin looked at the pile of sand under his feet and burst into tears.

Time is passing, Yang Lin's treasure hunt journey continues, until he reached the seventieth floor, Yang Lin finally found a huge alchemy furnace in a room, Yang Lin tried it out and found that this Dan furnace can still be tried and put it away with joy, this is Yang Lin's biggest harvest in the past few months.

"What is the Little Sword Pavilion in the Northern Regions, you are dead poor" Yang Lin stood in the center of the teleportation array on the tenth floor in a very bad mood, even the treasure hunting rat became sluggish because he hadn't smelled the breath of treasures for several months, it seemed that the treasure hunting rat was also extremely disgusted with this boring treasure hunt.

"I know you're tired too, the next few floors are the residences of high-ranking monks, no matter what, you still have to have something" Yang Lin observed the displeasure of the treasure hunting mouse, cheered it up and said, as long as the treasure hunting rat smells the breath of treasure in the treasure hunting road behind, it will immediately become alive.

The treasure hunt rat squeaked twice to indicate that he was fine, Yang Lin nodded, and then came to the seventy-first layer in a burst of white light, and the cultivation that has the strength to live in the seventy-first layer must at least turn into a god, and the eyes of the treasure hunting mouse in the seventy-first layer just lit up, and then he gently jumped out of Yang Lin's arms and began to run forward, the corners of Yang Lin's mouth turned slightly, and then he showed light skills and followed the treasure hunting rat to run forward.

"This is a treasure?" Yang Lin said in disbelief as he looked at the completely dead plant in front of him.

The treasure hunting mouse squeaked a few times and clearly told Yang Lin that the dead plant in the pot in front of him was indeed a treasure, "Lao Jiu, what is this?" Yang Lin really couldn't recognize what this dead plant was, so he had to ask Lao Jiu for advice.

"Well? It's really a good thing, this thing is called millennium grass, the growth cycle is extremely long, tens of thousands of years, every thousand years will grow an inch taller, this millennium grass is not the aura to absorb the dead alive, but look at its appearance should also be close to 10,000 years of medicinal age, the role of the millennium grass is that the longer the year, the tougher, the inner armor made of the millennium grass is extremely soft, but its defense ability is enough to resist the thunder tribulation of the refining period" After some explanation from Lao Jiu, Yang Lin finally understood what this dead grass was.

Yang Lin pulled out the thousand-year-old grass by the roots, pulled it hard and found that it was indeed very tough, and then Yang Lin summoned the Aoki sword and slashed at the thousand-year-old grass. Under the splash of sparks, the millennium grass was not damaged, and seeing this, Yang Lin finally nodded with satisfaction and put the millennium grass away.

"But what is such a thousand-year-old grass enough for" Yang Lin was in trouble again at this time, and suddenly Yang Lin's heart moved, took the flower pot and checked it, and finally found a few seeds of the thousand-year-old grass in the soil, but whether this kind of seed can still grow is a matter of two words.

The treasure hunting rat sniffed in the seventy-first layer, and after confirming that there was nothing missing, he sent a divine sense to Yang Lin, Yang Lin nodded and took the treasure hunting mouse and teleported back to the teleportation array on the tenth floor, and found the thousand-year-old grass in the seventy-first layer, which gave Yang Lin great confidence, the emaciated camel is bigger than the horse, and no matter how the small sword pavilion in the Northern Regions is, it is also a sect in the spirit world, there will definitely be some leftovers, Yang Lin is full of expectations for the treasure hunt journey in the future.

In a burst of white light, Yang Lin disappeared into the teleportation array with the treasure hunting mouse in his arms.
