Although it was guessed that the ore vein should have opened up the passage to the Crystal Devouring Beast's nest before so many Crystal Devouring Beasts would appear, this was not enough to scare Xiao Zhan, no matter whether the matter was true or not, he had to break through.

Naturally, more than a hundred people could not enter it together, and non-combatants such as miners and forgers naturally would not enter it, leaving a few warriors to protect them, Xiao Zhan led more than a hundred guards from the weapon workshop deep into the mine. It was definitely an accident to encounter a crystal-devouring beast as soon as they entered the mine, and the group walked hundreds of meters without encountering a crystal-devouring beast, but they could see scattered traces of fighting, obviously Xiao Yuanlang and they took the first step to clear the crystal-devouring beast here.

The mine cave is deep underground, and Xiao Zhan still has the most general understanding of this place, and there are basically no mineral deposits on the top. There was no danger in the first layer, but when Xiao Zhan and his party entered the second layer, the figure of the Crystal Devouring Beast finally appeared, all of them were ordinary Crystal Devouring Beasts, and there was no threat to the team composed of more than a hundred martial artists above the half-step Origin Realm. However, as the strength of the Crystal Eater Beast became stronger and stronger, a faint roar told everyone that there was a powerful Crystal Eater Beast in this layer.

The mineral deposits of the second layer are naturally better than those of the first layer, but for Xiao Zhan, these are useless at all, unless he really wants to find a satisfactory one, unless he goes deep into the five or six layers underground, but in this way, he will definitely encounter the terrifying Crystal Devouring Beast.

"Boom!"

As soon as everyone had completed half of the journey, the Crystal Devouring Beast appeared, there were more than a dozen of them, and their strength was all in the half-step origin realm, these guys didn't test at all, and as soon as they appeared, they went straight to Xiao Zhan, a team composed of humans.

"Form a battle formation!"

Xiao Zhan let out a loud shout, and in an instant, more than a hundred martial artists drew their weapons together, and a simplest defensive formation was formed, which he had temporarily prepared for this trip to the mineral vein. To be honest, Xiao Zhan's memory of the war is too huge, he can clearly find countless powerful and terrifying battle arrays, but unfortunately these battle arrays are too high for the cooperation of each martial artist, not to mention the formation of combat power in a short period of time, even if it takes several years, it may not be enough. At this time, Xiao Zhan could naturally only choose the simplest battle formation.

This is the Great Array of Heaven and Earth!

Nine people can be in the array, and in the future, the battle array can be complicated with nine as the base, and the power of the Heaven and Earth Integration Array composed of more than 100 people is still very great.

Xiao Jiang, these martial artists above the Origin Realm, did not make a move, this level of Crystal Devouring Beast was a test for Xiao Zhan, now he needed to improve his cultivation, time was very precious to him, he had to seize every moment. Xiao Tie is undoubtedly the arrow character, this guy is definitely a violent character, in the face of more than a dozen rushing crystal devouring beasts, he was extremely excited, with a loud shout, the huge hammer in his hand turned into an afterimage, only to hear a loud "bang", a crystal devouring beast was directly smashed out by him with a hammer.

Although Xiao Tie's strength in the half-step Origin Realm was so strong that he was perverted, after all, he was only one person, and it was impossible for him to take care of more than a dozen Crystal Devouring Beasts at once. Xiao Zhan originally wanted to choose a Crystal Devouring Beast as a target, but looking at the Crystal Devouring Beast that was coming at a high speed, he suddenly gave up this idea, and now his skill was a joke for this kind of rough-skinned and thick-skinned beast, unless he could reach the half-step Origin Realm, it would be difficult to kill this Crystal Devouring Beast.

Frontal combat Xiao Zhan is not of much use, so he simply commands the battle formation in the center, and actual combat is the best way to test the power of the battle array. The first round of impact caused a great impact on the battle array, and the Xuan Qi of the martial artists below the Origin Realm could not be released, although it was possible to condense the momentum into a single force, it was impossible to twist the strength of all people into a single force.

Withstanding the first round of impact, the Crystal Devouring Beast was completely caught in the battle formation, and at this time, things became easier for the Xiao family martial artists who were armed to the teeth. This time, Xiao Zhan used all the Origin Realm weapons, although it was difficult for the half-step Origin to exert the true power of the weapon, but it was easy to use it to break through the defense of the Devouring Crystal Beast. More than a dozen Crystal Devouring Beasts were strangled in a short time, and under Xiao Jiang's command, everyone began to dissect the Crystal Devouring Beasts.

The Crystal Eater eats a special crystal, whether it is a force defense or a Xuan Qi defense, it is very high, and it is still very good to use it to build equipment.

Killing more than a dozen Crystal Devouring Beasts was just the beginning, and the group continued to move deeper.

......

Crystal Eaters are a kind of social alien beasts, and they are not individually strong alien beasts in the leyline world except for defense, but due to their social nature, there are basically few living alien beasts that are willing to provoke.

The Crystal Devouring Beast's Lair is a very special place, where countless huge crystals are condensed, and the defense power is terrifying, and it is difficult for a Soul Slashing Realm martial artist to shake it at all. People know that the Crystal Eater's Nest is the Crystal Eater's lair, but few people know that the Crystal Eater is actually a kind of alien beast raised by the Crystal Eater Clan, and the entire Crystal Eater Beast's Nest is the old nest of the Crystal Eater Clan.

In a palace made entirely of spars in the center of the Crystal Eater's lair, the Crystal Eater's patriarch, Cha Yuan, was entertaining a guest from the ground.

The lifespan of the Crystal Devouring Clan is generally not long, if the cultivation is unable to break through to the Origin Realm, it generally only has a lifespan of one hundred years, and after being promoted to the Origin Realm, it will increase to three hundred years old, reaching the Nirvana Realm to five hundred years old, and as for the Spirit Slaying Realm, it is eight hundred years old.

Cha Yuan is very old, as a powerhouse of the Spirit Slaying Realm, he is now more than seven hundred years old, if he can't break through to a higher realm, he doesn't have much to live. Who doesn't want to live forever, especially since Cha Yuan has informed the Crystal Devouring Clan for hundreds of years, he definitely wants to be able to continue this kind of rule forever.

It's a pity that it is too difficult to break through to the Spirit Slaying Realm, and Cha Yuan is basically hopeless in this life. When people are about to die, they will always become different, some will realize that they can give up all rights, while others will become even worse and do some heinous things before they die.

Cha Yuan is undoubtedly the latter kind of person, he wants to live longer, one day a human from the ground told him that he could break the shackles through sacrifice, he did not hesitate to slaughter many people, and his strong strength made him a tyrant completely.

"Can the master really be sure that through this sacrifice, this patriarch will be able to break the shackles and be promoted to the Immortal Realm?"

Cha Yuan's face had a look of anticipation, he could clearly sense the rapid passage of his life over the years, which frightened him so much that he did a lot of massacres of his people.

Wu Jifeng was dressed in a black robe, and the whole person looked like a magic stick, and he sat opposite Cha Yuan, with an unfathomable smile on the corner of his mouth.
