Under the leadership of Vice President Xu, Li Changsheng soon came to the depths of the building.

Vice President Xu's collection room naturally has some powerful prohibitions, and there is a layer of light film all over the stone door of the collection room, only one place is not covered with light film, there is a fist-sized groove there, it seems that as long as the prescribed token is inlaid with the prescribed token, this stone door can be opened.

Vice Principal Xu did take out a token, which matched the groove on the stone door.

Unexpectedly, Vice Principal Xu did not put the token on the groove on the stone door, but pressed it on the wall on the side, and a similar groove appeared on the wall instead.

Without hesitation, Vice President Xu put the token into the groove.

What is this operation?

Looking at Vice Principal Xu's operation, Li Changsheng felt that his brain was about to short-circuit, and this kind of operation was long insightful!

Is the groove in the stone door a trap? Or is it not Vice Principal Xu's collection room?

Click~

To Li Changsheng's surprise, the light film on the stone door disappeared, and it slowly moved to the side, and when it stopped completely, a secret passage leading to the bottom was revealed.

Well, the groove on the stone door is probably a trap! If someone thinks they have stolen Vice Principal Xu's token, and then puts it into the groove on the stone door, the consequences will be unimaginable.

Seeing this scene, Li Changsheng secretly raised his vigilance in his heart, if he encountered the relics of his predecessors in the future, he must be vigilant, if this predecessor and Vice President Xu had the same virtue, he could also avoid similar traps.

Dozens of night pearls are inlaid above the secret passage, exuding a bright brilliance, like day, dispelling the darkness around them.

"Alright, let's go down!"

Li Changsheng nodded, and followed Vice Principal Xu into the secret passage.

Upon reaching the end, a room appears with several bookshelves.

On each bookshelf, there are dozens of boxes of different sizes and specifications, these boxes are large and small, and the materials are not the same, there are wooden boxes, stone boxes, iron boxes, jade boxes, Li Changsheng even saw boxes made of soul crystals.

"These are my collections, you can pick any one!"

After Vice President Xu finished speaking, he stood aside and closed his eyes to recuperate.

Li Changsheng nodded, and slowly walked to the nearest bookshelf, these boxes were not locked, and they could be opened and viewed at will.

In addition, each box is engraved with an introduction to the relevant items.

Li Changsheng opened the nearest iron box, revealing a crystal clear orb.

Exquisite Orb: A high-grade water weapon that can increase the power of Sancheng's water skills.

In terms of value, high-grade treasures are worth at least hundreds of soul crystals, and the specific value depends on the efficacy of the treasure.

After reading the introduction, Li Changsheng began to check the rest of the treasures.

Obsidian: You can craft top-grade wind artifacts!

Essence of Earth: It can be absorbed by the Earth Demon Pet and increase its realm breakthrough probability! Note: The higher the level of the Demon Pet, the smaller the breakthrough probability.

Space Ring: Contains 30 cubic meters of space!

Water Spirit Grass: The essence of heaven and earth, containing a rich water energy essence, if it is absorbed by the same elves, there is a certain chance to improve the quality of the water system goblin, depending on the original quality of the goblin, the higher the quality, the smaller the chance. Note: Do not give non-aqueous goblins to absorb, otherwise there will be a danger of exploding!

......

Soon, Li Changsheng finished reading all the treasures.

These treasures are roughly divided into five categories, generally speaking, high-grade treasures, natural and earthly treasures, rare materials, exotic beast corpses, and treasures related to demon masters.

These treasures may be useless to Vice Principal Xu, but Li Changsheng is different, he can't wait to pocket all the treasures.

It's a pity that he can only choose one!

"Let's try my special ability first!" Li Changsheng said secretly in his heart, releasing his spiritual power to sense the energy fluctuations of these treasures.

Vice Principal Xu glanced at Li Changsheng and didn't say anything, this is normal, isn't it!

Among these treasures, some treasures have no energy fluctuations, or the energy is extremely restrained, and he can only sense the treasures that emit energy fluctuations.

The collection room is not large, and Li Changsheng's spiritual power is enough to cover the entire room.

The next moment, a radar-like picture appeared in Li Changsheng's mind, and nearly a hundred bright points of light appeared on it.

Among them, there are a few points of light that are even brighter, such as wind obsidian, water spirit grass, etc., which are almost all in the category of heaven and earth.

What Li Changsheng felt strange was that there were two points of light superimposed together, one of them emitted a pure earthy yellow halo, and the other was a ten-colored brilliance, and the energy fluctuations emitted by the latter were so strong that they were definitely the only ones he had ever seen in his life!

Following the direction of the two points of light, Li Changsheng stood in front of the bookshelves that he was the first to check, and there was only one stone box under the bookshelf, and the volume of this stone box was very large, with a space of several cubic meters.

This huge stone box, Li Changsheng naturally opened it, and inside was a complete corpse of a strange beast.

Rat's carcass: giant rat, living under the ice all year round, weighing thousands of pounds, edible meat. Fur garments are used to keep out the cold, and their sound can be heard for thousands of miles, and their hair can summon rats. For some special reason, its flesh activity is almost perfectly preserved.

The rat belongs to the category of high-level alien beasts, and as long as it is an adult, it can become a fifth-order demon pet.

The corpse of this rat was extremely well preserved, and even Li Changsheng didn't even find the wound, giving people the feeling that he had died of natural causes.

"This mouse corpse was probably found by the old man seven years ago, the cause of death is unknown, there is no external injury, its corpse has not been decomposed, the old man guessed that it may have eaten some natural treasures to cause death, but also kept its corpse from decaying, its flesh and blood activity is also well preserved, almost the same as when he was alive, the old man also wanted to dissect it, but that would ruin this rare collection, so it has been placed here!"

I don't know when, Vice Principal Xu appeared behind Li Changsheng.

In Vice President Xu's mind, the natural treasures eaten by the rat must have been digested and fused with the rat, otherwise how to ensure the flesh and blood activity of the rat, but although there are few such treasures, Vice Principal Xu has not never obtained it, plus such a complete rat corpse is too rare, Vice Principal Xu has no idea of dissecting, so the rat corpse has been retained and has become a collection.

It is not uncommon to use the corpse of a powerful goblin as a collectible, which can be appreciated, has a certain collection value, and can set off the master's strength from the side.

Almost without hesitation, Li Changsheng pointed to the corpse of the rat and said, "Principal, I choose it!"
