Zhang Yi really received a task the next day, which was to purify the bloody demonic qi around the formation. There is a special power contained in these bloody demon qi www.biquge.info, although it will make the demon beasts bloodthirsty, but it will also greatly promote the evolution speed of the demon beasts, allowing them to produce more high-level demon beasts.

Most of the sources of these bloody demon qi are the flesh and blood of demon beasts and a large amount of earth vein turbidity produced after the sacrifice of witchcraft to the demon god, and the high-level demon beasts produced by these bloody demon qi are like ripening fruits, with various defects, but they are very suitable for high-level cannon fodder.

Every time the demon beast and the monk fight, a large amount of bloody demonic qi will be generated, and a large number of Jindan and even cannon fodder in the Yuan Infant Stage will also be created.

Therefore, Zhang Yicai had to purify those bloody demon qi after destroying the demon beasts.

Because the power of the bloody demonic energy comes from the sacrifice of the demon god, these bloody demonic qi have a strong survivability, and it often takes decades to degrade in the natural sea of vitality, and it is difficult for ordinary spell attacks to decompose such power, only thunder and flame have a restraining effect on such power.

After Zhang Yi accepted the task, he set off, and it was still the same team of casual cultivators who were following him, this time their main task was to arrange a defensive formation to prevent Zhang Yi from being sniped and sneak attacked by demon beasts during the spell casting process.

Along the way, Zhang Yi and the others first came to the Wind Wolf Canyon, where great changes have really taken place, even if the monks set fire to their bodies after killing a large number of wolf demons, but there is still a large amount of bloody demon qi generated here, and the whistling wind in the valley is also mixed with a trace of blood-colored demon qi, and in some places with less wind, it is even tangled into a mess. The bloody demonic energy here attracts nearby demonic beasts to suck and fight, and produces more demonic qi, and the roar of beasts in the valley is endless.

"Go ahead, clean up the demon beasts here, and set up a formation to gather these demon qi together. Zhang Yi commanded.

"Yes," the monks all acted immediately according to Zhang Yi's instructions.

These monks took action one after another, forming a group of threes and twos, and scattered into this Wind Wolf Canyon, because they had the map provided by Zhang Yi, so they easily killed all the demon beasts entrenched in it.

Then among the few foundation building monks who knew the formation, they began to set up the formation, which was a huge wind attribute formation covering the Wind Wolf Canyon, and the name was the Wind Sweeping Cloud Array. This is an intermediate formation, a formation that is known for covering a huge area.

Because it has little lethality and doesn't have much psychedelic or auxiliary effect, it is not very useful. However, it can gather special vitality within the range of the formation without worrying about polluting the magic weapon, so it is widely used on this battlefield.

After the formation was set up, the winds in the formation turned into whirlpools, gathering all the bloody demonic qi in them into suspended blood-colored balls, and finally converging into a huge blood ball the size of several people.

The blood ball rolled, changing the image of a specious beast, like a strange living creature, so close that you could even hear the roar of the beast in it.

This is the weirdness of the bloody demonic energy, if it gathers enough and for a long enough time, it can even transform into a strange blood demon out of thin air. The blood demon is like the incarnation of the demon god, bloodthirsty, weird and cunning, as long as there is enough blood to replenish, and even has an immortal body.

However, the probability of this kind of blood demon appearing is very small, and most of the cultivation is below the Jindan stage, and even this bloodthirsty alien will give priority to attacking the demon beast that has absorbed a large amount of bloody demon qi, so it is feared by both sides and does not allow this alien to appear.

After Zhang Yi had completed the gathering of these foundation-building monks, he began his destruction and purification work.

Zhang Yi stood at the core of the formation and began to cast spells, countless Five Elements Yuan Force gathered, and five five-colored clouds manifested, surrounding the bloody demon balloon.

As the spell continued, the multicolored clouds slammed into each other.

There was a loud "boom", and these vitality were annihilated into a silver thunderball.

The skull-sized thunderball seemed to be attracted, and it instantly collided with the bloody demonic qi. These two powerful forces collided together, but instead of an earth-shattering explosion, they silently annihilated each other.

The most masculine and rigid thunder actually turned into nothingness along with the bloody demonic energy, leaving only a bunch of stunned monks. They had been prepared for an earth-shattering thunderstorm, but they didn't expect such a thing to happen.

Zhang Yi knew in his Yuan Qi induction that these bloody demonic qi were the most filthy, and the thunder had a strange reaction after splitting into this bloody demonic qi, and these two forces actually produced strange spatial fluctuations after mixing, and there was no trace when they melted into the space.

Zhang Yi thought about this phenomenon, the thunder is yang, the bloody demonic energy is yin, and by chance, it will actually transform into the power of space, and the wonder of creation is really difficult to guess.

After dealing with the bloody demonic qi here, Zhang Yi and the others rushed to the lake where the wolf king had been entrenched before. The bloody demonic qi here should have been thinner after experiencing a big upheaval, but Zhang Yi and the others did find that the demonic aura here was even stronger.

"Things seem to have changed again. Zhang Yi said. "The demonic aura here is indeed stronger, so it is probably occupied by the new Jindan demon beast here. ”

The other monks who followed also frowned, after a great battle, they had managed to get a less dangerous job, but it was too fast. They couldn't help praying in their hearts: "But don't have Jindan demon beasts and a large group of demon beasts coming, there is not much chance of winning the battle with the demon ** here." ”

Zhang Yi did not rashly intruder in the bloody demonic aura, but began to observe the situation on the periphery, but through these layers of bloody demonic aura, it was difficult to observe the inside thoroughly. It's just that I guess there shouldn't be many demon beasts here, it's not a big demon beast race here, and there has just been a large-scale bloody sacrifice here, so that such a strong bloody demon qi can be gathered. It was probably a powerful demon beast that made the situation here look like this after slaughtering a large number of demon beasts here.

Zhang Yi estimated the situation here in his heart, and estimated that if such a Jindan demon beast was really entrenched here, if he started a war here, he would have a better chance of winning against the other party blessed by the bloody demon qi.
