Leaving Qingyan City, Lin Xu's expression suddenly relaxed, in this place, he almost lost his life!

"I want to go to the Demon Beast Mountain Range!" Lin Xu said, "I need the demon crystal of the fifth-order demon beast to improve my strength!"

Han Xiaoqi nodded, she saw Lin Xu's terrifying cultivation method, but the fifth-order demon beast was not so easy to kill, and there was a lot of danger in this demon beast mountain range, fortunately, Lin Xu could use flying boots to fly, otherwise it would be too difficult to hunt a fifth-order demon beast in the demon beast mountain range.

After a while, Han Xiaoqi picked up a map, which was given to him by Feng Lie, since he was going to the Demon Beast Mountain Range, then he would take a look at it by the way, what exactly was here?

Maybe there are treasures there that will help Lin Xu's strength, so after paying attention, Han Xiaoqi asked Lin Xu to look at this map.

"There are treasures here?" Lin Xu said as he looked at the map in disbelief.

When it comes to treasures, everyone has an innate greed, and Lin Xu is no exception.

And there are also a lot of treasures on Lin Xu's body, this Tianxuan Sword is one of them, in addition, there are also spirit beads, Heavenly Rebellion Divine Scroll! But there is one thing that Lin Xu has always been very surprised, that is, a fragment of a map obtained in the abyss under the valley, he doesn't know what that map is, but from the map that resembles animal skin, Lin Xu faintly feels that the stripes on it are not simple.

Of course, he didn't care too much about the fragment of that map, after all, it was only a fragment, and he didn't know what year or month he wanted to get this map together.

But for the things in front of him, Lin Xu was extremely excited.

Anyway, he is going to the Demon Beast Mountain Range, and he happens to go here, maybe there are really treasures here, so he will make a lot of money.

What Lin Xu needed most now was the demon crystal of the fifth-order demon beast, so the two of them set off towards the demon beast mountain range according to the map!

The legend inside the Demon Beast Mountain Range is that there are seventh-order demon beasts, which are equivalent to the powerhouses of the human Nirvana realm, and the strength of these demon beasts is extremely strong, and they can raze a huge mountain to the ground in a single stroke, which is beyond the imagination of human beings.

And what Lin Xu is going to this time is the interior of the Demon Beast Mountain Range!

It's just that before that, they have to make some preparations!

Lin Xu needs to construct some items, and at the same time needs to buy some elixirs for healing, and more importantly, Lin Xu needs some special potions to expel ordinary demon beasts, or to hide his own breath.

Some drugs are applied to the body, so that their breath is not detected by the demon beast.

If he wants to enter the inside of the Demon Beast Mountain Range, Lin Xu must use these medicines, otherwise ordinary people will definitely die if they enter it, even if he can fly, he doesn't dare to be careless, after all, those demon beasts whose strength has reached the sixth or even seventh order can also fly, not to mention that there are some flying demon beasts living in the Demon Beast Mountain Range, if those flying demon beasts are discovered, he will be even more dangerous.

For Lin Xu's carefulness, Han Xiaoqi also agreed.

It's just that she understands in her heart that in this demon beast mountain range, although there are powerful demon beasts, but the number is very small, and this kind of powerful demon beasts are all in the Ten Thousand Beasts Demon Palace, which can be regarded as the top demon beast gathering place in the continent!

Even some powerful cultivators have joined the Ten Thousand Beasts Demon Palace, respecting the demon beasts as the master!

After all, this continent has always followed the law of 10,000 years, and the strong are respected!

After a few days, Lin Xu and the two came to the imperial capital of the Northern Underworld Empire again! In this huge royal auction house, Lin Xu spent 10,000 gold coins to buy the items he needed, and all the elixirs were of the highest quality, this time it was to go to the Demon Beast Mountain Range, not to ordinary places, life could not be joked, so Lin Xu didn't care about the money.

And the auctioneers in this auction house all know Lin Xu, the champion of the Spiritual Constructor Competition, and the guest elder of the Spiritual Constructor Guild, this name is extremely loud, so in terms of price, they give Lin Xu an extremely cheap price.

The Visiting Elders of the Spiritual Constructor's Guild enjoy this power!

As long as you become a guest elder of the Spiritual Constructor's Guild, no matter in any auction house in the Northern Netherworld Empire, you will enjoy special treatment in terms of price.

For this kind of benefit, Lin Xu also tasted it for the first time, and this big purchase allowed him to save about 5,000 gold coins!

"Isn't there a fifth-order demon beast's demon crystal here?" Now that he came to the auction house, Lin Xu also said the items he needed.

It's a pity that Lin Xu got a disappointed answer, no!

Although the fifth-order demon beast is not strong, after all, the fifth-order demon beast is only equivalent to a human Yin Yang Realm cultivator, but if you want to obtain the demon crystal of such a demon beast, you must ask a Yin Yang Realm powerhouse or a fourth-level spirit constructor to take action.

It stands to reason that such items should be found in a huge auction house such as the Royal Auction House.

It's a pity that there are a lot of fifth-order demon beasts, but few people dare to hunt them, after all, these kind of demon beasts generally live inside the Demon Beast Mountain Range, even Yin Yang Realm cultivators dare not enter the inside of the Demon Beast Mountain Range.

It is rumored that the demon beasts inside the Demon Beast Mountain Range are constantly infested, and there are even sixth-order and seventh-order demon beasts, under such rumors, only the cultivators of the Spirit Yuan Realm dare to go inside, and the rest of the people cannot enter at all, which also makes the demon crystals of the fifth-order demon beasts very few, but they are extremely precious.

"Mr. Lin Xu, I do know that there is an auction house that has the demon crystals of fifth-order demon beasts. "It was Bei Yingchen who received Lin Xu at the Royal Auction, and even he had great respect for Lin Xu today.

"Oh, even the royal auction house doesn't have the demon crystal of a fifth-order demon beast, will other auction houses have it?" Lin Xu was also surprised.

"Hehe, Mr. Lin Xu doesn't know, in fact, the royal auction house is only the largest auction house in the Northern Empire, but secretly there are many auction houses whose scale and the items auctioned are more valuable than the royal auction house. Bei Mingchen smiled lightly and said.

"There is such a thing?" Lin Xu was also extremely surprised.

"Three days later, there will be an auction meeting in the underground auction house, and almost all the powerhouses of the empire will go there, and there should be what Mr. Lin Xu needs. Bei Mingchen smiled.

"Well, in three days, I'll go in person. Lin Xu said.

"Mr. Lin Xu should bring enough money, because there should be more than one item auctioned there, maybe Mr. will be interested in many items, and if you don't have enough money, you can't buy it. Bei Yingchen's words also made Lin Xu a little dignified, although he had a lot of money at this time, he only had 100,000 gold coins, and a few demon crystals of a fifth-order demon beast also needed tens of thousands of gold coins, and these money were really not enough.

"If necessary, our royal auction house can recycle Mr.'s constructed items and exchange them for gold coins at a high price!" Bei Yingchen said, and at the same time, he also had the intention of wooing Lin Xu.
