Most of Mu Feifei and them are fourth-grade disciples, and a few are first-, second-, and third-year elite disciples, like Ao Bai, Sun Qitian, Hua Xiao, and Zali Rogge.

In the third grade, there are also two elite students who have reached the early stage of the Yuan Infant, they are Rousseau of the Titan Clan, and Michael, the Divine Son of the Angel Clan.

It was the Five Yuan Babies who were here to hold this line of defense.

Yun Cang said: "I was hunting the Underworld Beasts on the periphery, and when I found out that there was a tide of Underworld Beasts, the contact with the mentors had already been disconnected. ”

Hearing Yun Cang's question, Mu Feifei's face was a little gloomy and said, "Our communication spirit treasure is still in contact with the mentors, and this incident was caused by the Holy Clan. ”

Yun Cang narrowed his eyes: "Holy Clan, could it be that the emperor belongs to them?" ”

Mu Feifei nodded: "Emperor Gui brought a branch of the Holy Clan's Soul Tree and planted it in the River Styx, and the branches of the Tree of Souls will continue to absorb the power of the River Styx to grow."

And the Styx and the Celestial River are connected, if I think correctly, in the Divine Domain, the Holy Clan is also using the Soul Tree to absorb the power of the Celestial River at this time. ”

Ao Ling on the side said, "Once the power of the Heavenly River and the Styx River is taken away by the Holy Clan, it will be a huge calamity for all the races in the Divine Domain, and the Divine Domain will be destroyed in this calamity. ”

Yun Cang's face also became as gloomy as Mu Feifei: "Can you contact the Dao Divine Domain, do you know what the situation of the Divine Domain is?" ”

Mu Feifei shook his head: "The two banks of the Styx River are too far away from the Divine Domain, and the information has long been cut off, what we need to do now is to prevent the emperor from returning." ”

"This beast tide is because of the attraction of the Soul Tree to the Stygian Beasts, all the Immortal Beasts are rushing towards the source of the Styx River, and the Holy Clan does not know where they got the secret method that can manipulate the Stygian Beasts, and the Great Sacrifice Wine and the Mentor are all trapped by the Stygian Beasts."

The situation is even more severe than Yun Cang imagined, and even the great sacrificial wine that crossed the tribulation period was trapped by the beasts, so how can it be played?

As if he saw what Yun Cang was thinking, Huang Ruyu said: "The emperor has calculated all the power of the academy, and they have also paid a great price for controlling the underworld beasts, and the number of underworld beasts they control will not exceed the power of the academy."

If we can reach the source of the River Styx as soon as possible, we have a chance to destroy the branches of the Tree of Souls. ”

Huang Ruyu's eyes burned and asked, "Yun Cang, how did you come here through such a distant beast tide?" If we can use the same method as you to get past these beast tides, then there will definitely be a chance to stop the Holy Clan! ”

Time was pressing, and Yun Cang did not be verbose, and transformed himself into the image of a bird with illusion, and spoke out with the experience of the scavenging flock.

"Illusion?"

These scholars were stunned for a moment.

Yun Cang's method is not difficult to say, but no one has thought of it.

All they had been thinking about was how to kill through this beast tide and rush to the source of the River Styx, but they didn't think about blending in with the beasts.

Mu Feifei immediately clapped his hands and said, "Yun Cang, you used illusion to transform us all into a flock of birds, can you do it?" ”

Yun Cang shook his head: "My illusion can only be used on top of myself, but I can teach you the illusion. ”

The illusion technique used by Yun Cang is called the Earth Evil Transformation Method, which was found in some ancient books in the mirror world.

The disciples of the academy are all Tianjiao, it is not very difficult for them to learn a spell, and it is not difficult to learn the Earth Demon Transformation Method, if you don't require mastery, just mastering it, that is, it is a matter of one or two hours.

Just as the students who had learned the Earth Evil Transformation Method were teaching each other, Mu Feifei, Huang Ruyu, and Michael of the Angel Clan all walked towards Yuncang.

Mu Feifei asked, "Yun Cang, when you were separated from Inverit and the others before, were there many beast tides on the periphery?" ”

Yun Cang knew that they were worried about the safety of Inverit, Huang Ruxue, Angel Yan and others, so he immediately took out a few jade pendants and said, "Before leaving, I asked Inverit and them to put their essence blood on these soul fire jade pendants.

The soul fire in the jade pendant has not been extinguished, which means that they are very safe now. ”

Mu Feifei and the three of them were all relieved, after all, from the outbreak of the beast tide to the present, what they were most worried about was Inverit and the others who had never been traced.

Now that Yun Cang's arrival shows that Inverit and the others are fine, then they can also take the next step with peace of mind.

After about an hour, all the students had mastered the Earth Shattering Method.

Yun Cang was the first to transform into a bird.

The clouds are no longer scavenging sparrows, after all, scavenging sparrows are just bottom-level beasts in the sky on both sides of the River Styx.

He transformed into a three-star flying beast: the Dragon Eagle.

The body of the dragon eagle is larger than that of the peregrine falcon, and in addition to the gray iron feathers that are as hard as iron, the skin also has gray scales like dragon scales.

Not only on the skin, but also on the beak and talons of birds, there are such gray scales.

Most of the Dark Dragon Eagles have the strength of Jindan, and the elites among them have the strength of Yuanying.

Mu Feifei, Huang Ruyu, and Ao Ling, like Yun Cang, directly transformed into the Dark Dragon Eagle.

Dozens of Dark Dragon Eagles rushed directly into the sky, and there was no need for them to stay in this ruin.

Yun Cang said with a divine thought: "We also need to find a flock of dark dragon eagles and blend in with them so that they will not be discovered by the rest of the flock. ”

Huang Ruyu asked with some confusion: "There are only dozens of ordinary Dark Dragon Eagle Groups, and our complete number can be regarded as a real Dark Dragon Eagle Group." ”

Yun Cang smiled: "The illusion only changed us into the appearance of the Dark Dragon Eagle, but we don't have the breath of the Dark Dragon Eagle yet, so it is easy for the flying Dark Beasts to see through it and attack it in groups." ”

Huang Ruyu suddenly realized, and he said, although most people have not thought of the method of illusion, there are still some who have thought of it, but their illusion cannot be mixed into the group of underworld beasts at all.

The daring is not that Yun Cang's Earth Evil Transformation Method is special, but that they lack the breath of flying beasts.

The clouds and cangs flew directly into the sky, and the flying beasts flew at different heights in the sky, and the flight altitude of the dragon eagle was much higher than that of the scavenging sparrow.

Along the way, Yun Cang first took Mu Feifei and them to kill a few groups of scavenging sparrows, making the "human smell" on their bodies fade.

However, he found a group of dark dragon eagles, and after subduing them, he took them as his younger brothers.

In this way, they can be regarded as truly blending in with the flying beasts.

Flying is always faster than running on the ground, and with the help of Mu Feifei and the others, Yun Cang doesn't have to be as careful as before to kill the attacking flying beasts.

Most of these flying beasts who took the initiative to find the door were controlled by the Holy Clan, and Yun Cang rushed to the source of the Styx while killing them.

Killing and killing, there is no longer a flying beast with long eyes in the back to find the door, it seems that the Holy Clan's method of controlling the beast is also limited.

In the distance, a black river flows directly down from the sky, dotted with dotted lights, like a galaxy flowing down the sky.

At the source of the River Styx, they have finally arrived.
