Seeing the old man's solemn face, Mu Can couldn't help but panic.

"Sister Yun, what is the Demon Heart Mark?"

But no matter how Mu Can called Ziyun in his mind, he couldn't get a reply.

It was as if the purple cloud had disappeared after retreating to the reincarnation bead just now.

The fat man looked nervously at the grimace mark on the back of Mu Can's neck, and asked anxiously.

"Master, what is the Demon Heart Seal?"

On the other hand, Bing'er also pricked up her ears and looked at the old man nervously.

"The Demon Heart Seal is a unique mark of the Demon Realm, at the cost of sacrificing a part of one's soul, leaving a mark on a person's body, and those with the Demon Heart Seal, no matter where they go, will be sensed by this Demon Realm creature. “

The old man carefully observed the marks on Mu Can's body and explained.

"So will there be any side effects?" Mu Can touched it with his hand, but found that nothing was touched.

"Once a month, there will be a demon backlash, but this kind of demon heart seal is not impossible to solve. ”

The old man frowned, it seemed that this matter was not as simple as he imagined.

"The pain of the heart demon backlash is no less than cutting flesh with a blunt knife, but if you can survive it, then your Dao heart will be extremely tough. If you want to solve it, having a strong heart is the best way to solve it. The old man thought for a moment and patted Mu Can on the shoulder.

The meaning is obvious, if you resist the past, it should be regarded as a training for you.

"By the way, Can'er, what's going on here?" the old man looked at the devastated ground, and the battle just now almost overturned the entire pastoral mansion.

There are also the following group of representatives of various families who have lost their ability to fight after taking Mu Can's medicine.

"My second uncle was possessed by the demons and wanted to kill me, because the elixir you gave was unsuccessful, Master, and this time he set up such a game, but in the end he was killed by me. ”

Mu Can couldn't explain everything that happened, so he roughly described what happened to the master.

"Then your cultivation?" When the old man probed Mu Can's body, he found that Mu Can's cultivation had actually recovered.

"The apprentice had an adventure and ate a strange fruit, and then his cultivation recovered, and his cultivation returned to normal. ”

Mu Can thought about it and didn't say anything about the reincarnation bead, Ziyun had already reminded him that even if he was the closest person, he couldn't say anything about the reincarnation bead.

It's not that he doesn't believe them, but in the face of great temptation, Ziyun can't guarantee that everyone can keep secrets.

Even if Ziyun exists, Ziyun, who is only a remnant soul now, can't protect Mu Can in front of the top masters in the human world.

Crouching Tiger, Hidden Dragon in the human realm, for the heavenly realm, can be regarded as a forbidden land in a certain sense.

"That's good, here's the matter, come back to the academy with me. ”

I can feel that Mu Can is a little hidden, and the old man doesn't care, Mu Can has been by his side since he entered the academy at the age of ten.

For his apprentice, the old man is still very confident.

"Well, that's natural, the apprentice still wants to practice with the master, by the way, master, why are the junior brothers and sisters here, but they haven't seen the senior brother?"

Mu Can hesitated to ask a question, Hu Dingyi and Bing'er both came with the master, but they were missing the senior brother who took the most care of him at the beginning.

Hearing Mu Can's question, a rare expression of pain appeared on the old man's face, which was simply too unusual for a person who had cultivated to Tongtian to become the vice president of the academy.

"What's wrong, is something wrong with Senior Brother?" Mu Can saw the expression on his master's face and knew that things didn't seem to be so simple.

With the care of his senior brother, he knew that something had happened to him, and he would definitely be the first to arrive.

But now it doesn't appear at all, so there is only one explanation, there is something wrong with the senior brother.

As soon as the fat man heard the mention of his senior brother, the mist that had just dispersed in his eyes gathered again.

"After you had an accident and left, Senior Brother had a conflict with the Eastern Emperor, lost a duel, and left the academy saying that he was going to practice in the Ten Thousand Demon Caves, and he didn't come back for three years. ”

As he spoke, the fat man's tears flowed again.

The Ten Thousand Demon Cave is known as one of the ten forbidden places, known as the Little Demon Realm in the human world, and it is a place where ten thousand demons gather, and what cultivators have to face when they enter is an endless battle.

Throughout the history of cultivators, there are only a few people who have successfully entered the Ten Thousand Demon Caves and left.

And most of these people have soared to the immortal realm.

As soon as he heard the name of the Eastern Emperor, Mu Can gritted his teeth fiercely, this name has always been the driving force for Mu Can's cultivation in the past three years.

Enemies, enemies of life and death.

"It's the Eastern Emperor again, if something goes wrong with the senior brother, the Eastern Emperor, I will definitely destroy your entire clan. ”

A tyrannical aura poured out of Mu Can's body, and the temperature around him seemed to have dropped a little.

"Brother Can, the grimace is smiling, and the grimace behind you is moving. The little fat man pointed to the mark on Mu Can's body and said.

The grimace on Mu Can's neck actually made the same expression as a person, and the already terrifying devil mark actually grinned, as if he was laughing.

"Stabilize your mind, don't be shaken by demonic energy, you must not have too much mental fluctuation, this kind of demonic general-level heart demon seal will not stir your heart demon all the time. “

Seeing this scene, the old man immediately held Mu Can's hand, and slowly calmed down the energy in Mu Can's body that was seduced by the inner demon and had a tendency to rage.

After a while, Mu Can regained his composure, and the demon mark on his neck returned to normal.

"Don't be tempted by the Demon Heart Seal, this is the most dangerous place for the Demon Heart Seal. As for your senior brother, I'm sure he'll be fine. “

The old man saw that Mu Can had regained his composure, and said lightly.

Mu Can is his favorite disciple, and the senior brother in Mu Can's mouth is his most optimistic disciple.

"Master, after I go back, I will go to the Ten Thousand Demons Cave, no matter what, this matter is caused by me, even if it is hell, I will bring my senior brother back. There is also the Eastern Emperor, I suspect now that I fell into the Falling Eagle Stream, and it is also related to the Eastern Emperor, if it is confirmed, I will challenge him head-on. “

Mu Can said firmly, everything started because of himself, this Eastern Emperor has been in Mu Can's heart for three years.

Like a thorn, Mu Can's painful cultivation every day is to be able to go back to take revenge one day.

"Don't worry, although the master is not the strongest, but the juniors' affairs, let the juniors deal with it, if anyone dares to interfere, then I won't just look at it, that Donghuang, relying on his family background to make the academy into a miasma, I have long been displeased with him. He also dared to plot against my two apprentices, and last time if it wasn't for the dean to stop him, I would have let him dare to jump in the academy. “

When it comes to the Eastern Emperor, the old man is also quite resentful, relying on his identity as a prince to gang up in the academy.

The last time his eldest apprentice was defeated in a duel and left the Ten Thousand Demon Cave, the old man had already looked for the Eastern Emperor, but he was indeed stopped by the dean.

But this time, if Mu Can goes to the Eastern Emperor for trouble again, I believe that no one will come out to stop him again.

It's just Mu Can, can he defeat the Eastern Emperor?
