In fact, Xiao Chen didn't know at the moment that what he was going through at the moment was a catastrophe to deal with all the monks, and this catastrophe was not from the outside world, but was born from the heart, and it was determined by the heart, so it was called the heart tribulation! Countless monks with amazing talents and rapid progress in their early years led to the later stage of being obscure to everyone, and finally disappeared into the vast sea of monks and were no longer inconspicuous.

The mental tribulation is formless and substantial, but it can cut off the path of the monk's path! This calamity appears at different stages depending on the degree of mental toughness of the monk. There are those who are weak in heart and do not want to forge ahead, and the Jindan realm will come, and there are also different levels of Yuanying, non-falling, merging, and crossing, which vary from person to person.

Xiao Chen established his mind this time, but he had already broken this heart tribulation, as long as this thought was not broken, he would not be troubled by the heart tribulation.

The unicorns, the desert plains.

The sky is full of wind and sand, the sun is shining, the air is dry and there is no moisture at all, and the ground soil layer has been eroded for a long time, and now it has turned into yellow sand everywhere. The sun shines on the ground, drying the sand and heating up rapidly, making it extremely hot in the wilderness. As for the night, when the sun sets, the temperature of the sand drops suddenly, and it is as cold as ice, and the temperature difference between day and night is very large. In addition, it is extremely barren, and the wind does not cover the sky and the sun all year round, resulting in a barren place.

But it is in this barren land that some special brute beasts live, such as sand ants, all of which are the size of an adult's arm, and their bodies are covered in jet-black carapaces. This brute beast survives by devouring grains of sand, absorbing the iron in it to evolve, making its carapace as strong as iron, making it an excellent material for making weapons. As for the pair of chewing teeth on the mouth, it is extremely sharp and barb, and a bite can easily tear apart the monk's flesh and remove a large piece of flesh and blood.

There are also sand scorpions, which are of different sizes, the small ones are about the size of a foot, but the large ones are like calves, with long tails, and are highly poisonous, among which the toxins have a very strong lethality for the monks, and they are invisible killing weapons, and they are sold for a lot of money after they are successful.

In addition, other special brute beasts such as sand snakes and sand spiders have a special physique, and they almost do not need to take water from the outside world in their lives, otherwise they will not be able to survive in this harsh environment.

The desert plain is located in the territory of the unicorn tribe near the southwest, there are 300 million miles in the square, the real vastness, like the sea of sand, starting from the periphery, the more you travel to it, the more bad the environment, it is rumored that there are more powerful sand beasts in the depths of the sand sea, even if the peak powerhouse of the heavenly and human realm enters it, it will not be pleased.

As one of the hundred clans in the spirit world, the unicorn clan naturally has countless strong people, and in the early years, they also suspected that the strange appearance of this sand sea was strange, and there were treasures in it, so they sent the strong people in the clan to explore. Although it is not known what the specific outcome will be, the matter is finally closed.

Over the years, the sand sea has been slowly expanding, but in the eyes of the unicorn monks, it is just a desert land, and there is no more treasure opportunity. But even so, the existence of sand ants, sand scorpions and other brute beasts here still brings a bit of life to this sea of sand.

Starting from the edge of the sand sea, there are vaguely some small cities in the sand, they are not established by the unicorn clan, but the major merchants in order to purchase various brute beast materials nearby, the safety factor is naturally greatly reduced, and every few years will be hit by the sand sea brute beasts, with heavy casualties and blood flowing into the sea. But this did not deter the enthusiasm of the unicorn monks, and the high profits were enough to make them take risks until they finally died in the sea of sand.

Beisha City is a small city on the edge of the Sand Sea, although it is not big, but as the first city on the edge of the Sand Sea, the monks who enter or leave will choose to stay here for a while, rest and then leave, coupled with the entry of major merchants, this deserted small city is extremely prosperous, and the number of mobile monks has reached an incalculable level.

Right now, outside the south gate of the city, there is already a long queue lined up, and they are paying spirit stones one by one to enter the city. Since this city was built by merchants, if you want to enter it, you naturally need to pay spirit stones, but fortunately, the price is not high, and no one has made trouble because of this little money for many years.

"Brother Chenxiao, this is Beisha City. A unicorn woman chuckled and spoke, this woman looked young, with a slender and beautiful little horn on her forehead, almost transparent, which not only did not look weird, but added a bit of liveliness and loveliness.

A unicorn monk beside him nodded slowly when he heard this, looking at the small city in front of him, and the strange color in his eyes flashed, without causing anyone to notice. Although his appearance is unfamiliar and his shape changes, those dark eyes and the calm meaning in them are enough to show his identity.

This unicorn monk is actually Xiao Chen!

After deciding to come to the secret realm of the Yaksha Clan's great power that day, Xiao Chen had already begun to prepare, and in order to avoid trouble, he learned about a special elixir, the Transfiguration Pill, through Curry. As the name suggests, after swallowing, it can transform into the race of the mind, and as long as it does not release the medicine on its own during the period, it can last up to a year.

For more than ten days after that, Xiao Chen was in a hurry to collect the materials of the Illusion Pill, but this Pill was extremely rare, and one of the materials was extremely rare, and he ran several cities in a row but did not find it. When he was about to give up, he happened to meet a group of monks who wanted to go to the desert (sand sea), and coincidentally obtained the last taste of ingredients from them.

Xiao Chen was overjoyed to complete the refining secretly, so he walked forward with this team, and on the way, he also heard a lot of information about the sand sea without a trace, hoping to help him in the future, although it took two more days, but in Xiao Chen's opinion, it was extremely cost-effective, at least for now, he already had a preliminary understanding of this desert plain.

"Hmph, as a monk of my unicorn clan, it is ridiculous that I don't know the desert plain. Not far from the two of them, a sturdy young unicorn monk spoke in a low voice, his eyes looked at Xiao Chen defiantly, his dissatisfaction was not concealed at all, from his occasional gaze on Xiao Chen and the unicorn girl, he could easily judge the thoughts in this person's heart.

"Blood Tiger, Brother Xiao Chen is a refiner, his cultivation is not as good as you and me, it's normal that you haven't been to the Desert Plain, how can you speak like that!" The unicorn girl glared at this playmate who had grown up together, and she didn't know why he had been embarrassed with Brother Chenxiao for the past two days.

The blood tiger's smug and sneering face collapsed instantly, and the girl opened her mouth to speak for Xiao Chen, which made his heart feel even more gloomy, and he was about to open his mouth with a sneer, but at this moment, there was a hoarse but rather majestic shout.

"Okay, now that you've arrived in Beisha City, you two are not afraid of being laughed at by other 'beast hunters', so you don't have to say a word. "The person who came was a unicorn monk in his fifties, with a slightly dark complexion and a slight chapped complexion.

"Yes, Daddy. Lisa pursed her mouth, twisted her waist and walked to Xiao Chen's side without speaking.

As for the Blood Tiger, after respectfully calling out to the master, he walked directly to the back of the team, and his face was full of the meaning that no one should approach.

"Hehe, don't take it to heart Chenxiao Daoyou, my disciple is just some, hehe, hehe, actually has a good heart. "The old man of the unicorn clan is codenamed Earth Scorpion, his real name is unknown, but he is the leader of this team that hunts Sand Sea Barbarian Beasts, and his cultivation is at the middle level of the merger, and he is not a big master, and he has led more than 20 clansmen to make a living by taking risks.

Xiao Chen smiled and shook his head, with his current cultivation state of mind, he naturally wouldn't be serious with a jealous little guy, besides, he was going to leave here, this sea of sand, he needed to enter alone.

Seeing this, the ground scorpion smiled, and looked at Xiao Chen deeply without a trace, the young clansman in front of him did not show any abnormality, calm and quiet, without the arrogance and frizziness of the young clansmen now, but it was his calmness that made him look down and always couldn't help but secretly feel a little awe in his heart. Since the birth of the ground scorpion, I don't know how much bloody rain it has experienced, this life is crawling out of the pile of dead people, although the cultivation is not high, but the cultivated pair of eyes are extremely vicious. Although the ground scorpion was surprised by the inexplicable awe of his own family, he finally decided to be careful not to make enemies with this young clansman. That's why he sold the materials of the Illusion Pill at an extremely fair price, and he was also quite affectionate to Xiao Chen along the way, and they became familiar with each other.

Standing outside the city gate, Xiao Chen's eyes swept lightly around him, and he nodded slightly in his heart. This unicorn clan is worthy of being one of the hundred clans in the spirit world, there are really a lot of strong people, only among the "beast hunters" attracted by this sand sea, there are many strong cultivators, among which the realm of immortality is the main, followed by the yuan baby, and the combination is the least. As for the existence of the Tribulation Realm, there is no one seen here. This is also normal, although the materials on the brute beasts in the sand sea are expensive, but it is only for the monks below the merger, for the monks of the catastrophe, let them obtain spirit stones by hunting the brute beasts, it is obviously a very important thing, unless there is a reason, it is very rare for the monks to enter the sea of sand.

Following the people into the city gate, Xiao Chen stopped, hugged his fist to the old man of the unicorn clan, and said: "Scorpion Daoist, you and I will separate here, Chenxiao will buy some materials in the city, and I will not go with you, you and I will have a period later." ”

The ground scorpion nodded and said with a smile: "That is the case, the old man will not stay longer, but my unicorn team will always be friends of Chenxiao Daoyou, we will often haunt Beisha City, if you need help in the future, you can come here directly to find us." The man spoke, but his voice was earnest.

Xiao Chen smiled and nodded, then greeted Lisa and the others, and turned around and strode away without hesitation.

For Xiao Chen, a clansman who is quite humble and gentle, Lisa likes it quite a lot in her heart, and she is a little reluctant to see him leave, but the blood tiger's heart suddenly relaxed, and a long-lost smile appeared on her face.

"Let's go. The ground scorpion waved his hand, and was about to leave at the moment, but suddenly a sneer came from behind him, "Hehe, isn't the ground scorpion Taoist friend of the one-horned team ahead, old friends meet, why are you in such a hurry?"
