Lin Lei's room was not big, but everything was well organized.

Because the room was not very large, Lin Xuan looked at the whole room as soon as he walked in, in Lin Lei's room, there were only some ordinary changes of clothes and a small amount of personal items, and the rest was only a dilapidated wooden bed and a wooden table with a table lamp.

Although he was a little embarrassed, in order to ensure his life in the next few months, Lin Xuan still opened the cabinet of his father's wooden table with some apologies, but unfortunately, there were only a few ordinary books and ballpoint pens. I didn't see any cash or bank card passbooks or anything like that.

"Hey...... Not to mention hair, I didn't even find a fart. Lin Xuan sighed a little disappointed, but just as he was about to leave Lin Lei's room. Suddenly I felt a little spiritual power fluctuation in the room,

Fluctuations in spiritual power?

Lin Xuan's eyes lit up, what could cause spiritual power fluctuations wouldn't be too bad in comparison, right?

As soon as he thought of this, Lin Xuan's morale was greatly boosted, and he began to carefully perceive the slight aura fluctuations,

Finally, after spending a little time, Lin Xuan finally discovered where the aura came from.

"That's it!" Lin Xuan turned his head to look at the corner of the room, which looked empty, but in Lin Xuan's careful perception, he found that there was an extremely slight aura flowing slowly, stirring up a trace of spiritual power fluctuations.

"There should have been a formation laid out by my father." Lin Xuan said to himself, in the cultivation experience that Lin Lei passed on to him, he had a lot of knowledge about formations or pills.

Formation, elixir, these are the two basic skills that are indispensable for immortal cultivators.

Needless to say, the pill is so great that it can make the road of cultivating immortals countless times better, and there is a legend that if there are enough heavenly and earthly treasures, you can refine the legendary Nine Turns Golden Pill, one is enough for an ordinary person to have enough aura to cultivate to the Heavenly Immortal Realm, but unfortunately, this elixir is said to have only been refined by the Dao Ancestor Hongmeng in ancient times to give him the most beloved little disciple, and then no one can refine it.

And another precious thing that can be compared with the elixir, that is the formation.

The formation, based on the way of heaven and earth, and with all kinds of heavenly and earthly treasures as the eyes, can make the arranged formation have all kinds of incredible abilities, and it is a way to use the power of heaven and earth to serve oneself.

If you are proficient in this way, you can even arrange a formation that can compare the power of a nuclear bomb.

However, after all, this is only a minority, and most of the general immortal cultivators arrange these formations to condense a small amount of spiritual energy between heaven and earth to increase the speed of cultivation, or to lay down all kinds of defensive formations to protect the cave or their own body, you must know that cultivators have a catastrophe, and if they can't cross it, their souls will spread, and who in this world is not afraid of death? Therefore, almost every immortal cultivator will study several defensive formations just in case.

And now, according to Lin Xuan's guess, the formation on this wall should be a small formation similar to a defensive formation. If you want to take out the contents of it, I'm afraid you have to break this formation first.

"It's a pity that I don't know anything about formations." Lin Xuan frowned and groaned for a while, and finally could only shake his head helplessly.

"Since it can't be broken with the way of the formation, then the rest can only be broken with force." Lin Xuan thought about it, clasped it with his fingers, and gently knocked on the wall, not daring to push too hard, for fear that if the things inside were some fragile items, it would be bad if they were broken.

As a result, De Lin Xuan's spirits were lifted, and as he expected, this wall did have a formation, because no matter what Lin Xuan's right hand did, it was like a layer of invisible glass when it was about a centimeter away from the wall, so that De Lin Xuan's hand could not touch the wall.

"Sure enough, there is a formation." Lin Xuan smiled, his palms clenched into fists, and he smashed towards the wall with Yicheng's strength, but he couldn't get in.

"It's quite strong," feeling the touch from his fist, Lin Xuan said to himself, fifty percent of his strength, more than five hundred catties of strength under the hammer, but unfortunately, it still can't be broken.

"Very well, how about trying all my strength." Lin Xuan's fists were clenched, no longer retaining half of his strength, his arms were raised back, his spine was like a big bow jumping tightly, he let out a low cry in his mouth, and his whole body instantly exerted force, and his fist also crossed a trajectory that could exert the most force, and a punch pierced the wall.

Bang!

It was as if the whole wall was shaking.

Pity.

It's not broken!

"Huh, the formation is really magical, it seems that if I want to get the things inside, I have to learn the formation first." Lin Xuan shook his fist, which was a little painful, sighed, and prepared to leave to find another way.

But just as he was about to leave, his heart moved, and he mobilized the spiritual power in his body to spread all over his palm, and casually touched towards the wall.

In Lin Xuan's stunned gaze, his arm stretched into the wall unhindered, as if he was sticking into another space, that scene could only be seen in science fiction.

"It actually succeeded, could it be that this is a formation that only immortal cultivators can enter?" Lin Xuan muttered to himself, understanding the usefulness of this formation.

The space in the wall was not large, Lin Xuan could grope with one hand, in it, he only touched something similar to a box, and pulled it out with force, it turned out to be really a box.

The box is made of a rare tree with red patterns, which looks very quaint and atmospheric.

Lin Xuan took a light breath and opened the box.

Seeing that the palm-sized box only had three small bottles, Lin Xuan casually picked up one of the bottles and shook it, and there was a low collision sound inside.

"Is this an elixir?" Lin Xuan's heart moved, and he hurriedly opened the cork, if it was really an elixir, maybe it could make his cultivation speed several times faster again.

The cork of the bottle was opened, and several pale green pills the size of little fingers rolled from the bottle onto Li Xuan's palm.

"Sure enough, it's an elixir!" Looking at these round pills, Lin Xuan was so excited that he wanted to sing, but he still suppressed his excitement, and used the memory in his brain to briefly judge the usefulness of this elixir, and then, he was a little disappointed.

These pills are not pills that can enhance cultivation, but an ordinary healing pill commonly used by immortal cultivators, the Rejuvenation Pill, which can make the wounds of the best quickly compound. And what's even worse is that the efficacy of this elixir will weaken with the increase of the ** strength of immortal cultivators, in other words, this elixir is only of some use to low-level immortal cultivators.

Lin Xuan immediately opened the other two bottles and was disappointed again.

A bottle is the spirit of recuperation, as long as ordinary people eat one, even if they don't sleep for ten consecutive days, they are still alive and well. However, this is of a fart to the current Lin Xuan.

There is also the last bottle, it turned out to be a bottle of poison pill, and the toxin contained in one is enough to poison hundreds of elephants, obviously, this is for immortal cultivators, so that Lin Xuan's bones are cold, this road of immortal cultivation is really not so easy to walk, if you are not careful, you will die without a corpse.

"Hey, dad has a fart for keeping this thing, it's better to leave a few yuan." Lin Xuan closed the box and said dejectedly.

"Wait!" As if thinking of something, Lin Xuan's eyes lit up again.

This elixir is of little use to me, but it is undoubtedly an absolute supreme elixir for ordinary people, especially this rejuvenation pill, as long as there is one breath left, it can be saved.

"Or? Sold them? Lin Xuan looked at the box, his heart beating violently. His eyes became brighter and brighter, and he said to himself, "Selling them should be enough for me to spend a few years, right?" ”
