"Don't worry, as far as the three of us know, there is no way for others to know." Zhang Dong said comfortingly.

"We have to be careful, and you don't go too far, otherwise, it will be a big disaster." Bei Rong said.

"Don't worry, I'm measured." Zhang Dong patted his chest and said.

The three of them walked out of the alchemy room and entered the practice room.

Zhang Dong did not practice in the practice room, but directly entered the fairy cave.

Ding Qiao and Bei Rong, who were very confused in their hearts, had already been dragged into the water, so naturally they didn't stop them, nor did they follow them, and sat cross-legged guarding the fairy cave.

Zhang Dong appeared directly in the misty room, and said with a smile to the jade bottle in his hand that was adjusting his mind and body on his knees: "Ethereal, what do you think this is?" ”

The mist stood up, took the jade bottle, and when she opened it, she was shocked on the spot, because there were two hundred god-level puzzle pills inside.

She finally came to her senses and asked excitedly, "Childe, have you really advanced to a god-level alchemist?" ”

Zhang Dong explained the situation again, and finally said: "I have hidden a total of 400 pills of these pills, half of us, and with these pills, the probability of you breaking through the bottleneck must be very high." ”

"Childe, you're amazing."

The misty snuggled into Zhang Dong's arms excitedly, hugged Zhang Dong's neck, and said with a smile.

"Ethereal, now you give me the Dharma Protector, I will deal with a powerful being, and see if I can break the slave seal in his soul." Zhang Dong said solemnly.

The powerful existence he said is naturally the purple-haired old demon, the immortal Hades Emperor sent him to destroy the earth billions of years ago, and then was imprisoned by the Ice and Snow Emperor in the ice and snow secret realm of the earth, billions of years later, he got out of trouble, but met Zhang Dong, the nemesis, and imprisoned the soul of the purple-haired old demon with a soul devouring bottle, and never paid attention to it.

After all, at that time, he was only at the level of the Grandmaster, and if he wanted to break the slave seal of the immortal Emperor in the soul of the purple-haired old demon, it was estimated that he would not be able to do it, but now that he had cultivated to the fourth level of the Grandmaster, he would soon start an operation to save the Taishang Laojun, and if he couldn't break the slave seal in the soul of the Taishang Laojun, there was no way to save him.

So, he wanted to do an experiment.

Once he can break the slave seal in the soul of the purple-haired old demon, then he should be able to break the slave mark in the soul of the Taishang Laojun!

Of course, there is a certain danger in this experiment, because the Slave Mark is aggressive, but he has to do it!

So Zhang Dong sat cross-legged and looked at the Soul Eater bottle in his hand with burning eyes.

Misty naturally stood to the side with a guarded face, holding a sharp short sword in both hands, as long as she felt that the situation was not right, she would launch a fatal blow to relieve Zhang Dong of danger.

Wisps of black smoke flew out of Zhang Dong's mind, and then into the Soul Eater bottle.

This is, of course, his soul energy.

And the Soul Eater Vial is his own magic weapon, and of course it is impossible to harm the master's soul.

Soon, all of Zhang Dong's soul entered the Soul Eater Bottle, which was a blood-colored world, revealing an eerie and chilling feeling.

Without hesitation, he sank directly into the depths of the bottle.

"Ah......h

Before he completely sank to the bottom of the bottle, he heard a terrible scream, of course, this was sent by the purple-haired old demon, the soul devouring bottle can devour his soul energy, although his soul energy is huge, but he can't resist such a long-term devouring, so, his soul has become very weak, and this feeling of being devoured is really extremely painful, and the scream is natural.

"Hahaha......"

Zhang Dong's soul energy was combined into a human body that was exactly the same as Zhang Dong's body, and landed in front of the purple-haired old devil's soul body with a bang, when he saw the soul of the purple old devil like a mosquito trapped in the glue, struggling desperately, but he couldn't get out, and he was so painful that he died and lived, embarrassed like a water dog, Zhang Dong couldn't help but bend over and laugh.

The purple-haired old demon only found out that Zhang Dong was coming at this time, and the screams stopped instantly, projecting a resentful gaze on Zhang Dong's face, and said angrily: "Zhang Dong, you will never be able to help me, you will never be able to kill me, soon, I will get out of trouble, and soon, you will be killed by the Immortal Emperor ......."

"Haha...... Purple-haired old devil, now you are like a shrew scolding the street, today, I will let you see my methods. After Zhang Dongwei finished speaking, his big hand slowly reached out, and a slave seal was formed in an instant, revealing a cold and mysterious aura.

"You, you...... He even cultivated the way of slaves? The purple-haired old devil's face was shocked, and his eyes were full of horror,

Last time, he was also caught and imprisoned by the Ice and Snow Emperor, but the Ice and Snow Emperor did not practice the way of slavery, but he also knew how to control people with his soul, but his power was naturally limited, and there was no way to control his soul, and there was no way to extract his soul from his mind, but now it is different, his soul has been separated from his body, and he is weak, Zhang Dong seems to be practicing the way of slavery again, and the situation is really not good.

"The way of a slave? I really don't know how to cultivate, don't be afraid. ”

Zhang Dong smiled evilly, to tell the truth, he did not find the way of slavery, but this slave seal was what he learned from the way of swallowing and transforming the constant technique, which was even more magical than the slave seal of the way of slave.

After saying that, he did not delay, and immediately ordered the slave seal to be fiercely covered on the forehead of the purple-haired old demon.

Then he took two steps back vigilantly, believing that once the slave mark was formed on the soul of the purple-haired old demon, the slave mark imprinted by the immortal Hades would appear, and he would have a big battle with his servant mark.

"Ah......h

The purple-haired old demon let out a terrible scream, and a red light like a flame appeared on his forehead, as if it was being burned by a red-hot soldering iron.

Finally, the seal completed its mission and stepped away.

However, the purple-haired old devil left a distinct servant mark on his forehead, but the strange thing was that the purple-haired old devil's forehead began to crumble, and together with the slave mark, it collapsed into black smoke, and after a while, the soul mark on his forehead completely disappeared and ceased to exist.

"Hahaha...... "The purple-haired old demon let out a maniacian laugh, "Zhang Dong, you want the soul to control me, it's just a dream." ”

Zhang Dong's face really showed disbelief, he had easily controlled so many demon masters in such a way, and even broke the slave mark in their minds, now the soul of the purple-haired old demon was so weak, he didn't even see the soul mark under the immortal Hades Emperor to show his power, so he made the slave mark of his brand collapse, how could this be possible?

Could it be that the purple-haired old demon also cultivates a secret method to protect the soul?

Or is it because his cultivation is too low, his realm is too low, and there are too many purple-haired old demons, so he can't control his success?

"Purple-haired old devil, don't be complacent, I don't believe that the soul can't control you." After Zhang Dong finished speaking coldly, he once again printed it on the forehead of the purple-haired old demon with a slave seal.

But it was still the nephew who hit the lantern, and the mark collapsed again.

In the ridicule of the purple-haired old demon, Zhang Dong's soul flew out of the Soul Eater Bottle and returned to his body, his face becoming solemn.

All of this naturally fell into the misty divine sense, and she recommended herself: "Let me try, maybe I can control him with my soul." ”

Zhang Dong nodded and agreed, if the misty misty could control the purple-haired old demon with his soul, it would also be a great thing.

The misty method is very different from Zhang Dong's, there is no soul out of the body at all, it is just a strange seal that is combined with countless slave path heaven and earth rules, like a mist, which looks very mysterious, and sinks into the soul devouring bottle like lightning, and covers the forehead of the purple-haired old demon's soul body, forming a very bright red mark.

But the strange thing is that this soul mark collapsed in an instant, faster and more completely than the slave mark that Zhang Dong cast.

"Hahaha...... You are really naïve to have such a clumsy soul control method to control people, and you want to control me. The purple-haired old demon let out a rampant laugh.

Zhang Dong's face turned iron-blue, a raging anger surged in his heart, and the misty misty face was also ugly, and he said hesitantly: "Childe, I haven't found the way of the slave for too long, so the power is very weak, not as good as the slave seal you cast, and this guy is the henchman of the Immortal Emperor of the Underworld, and he may know some magical secret methods." ”

"Let me think about it."

After Zhang Dong finished speaking, he closed his eyes and asked in his heart: "Monitor, have you collected any secret information to protect the soul?" ”

"I haven't collected it, after all, I can't read the memories of monks above the grandmaster level." The monitor said apologetically.

"Si Ji, is there a way for you to let my soul control the purple-haired old demon?" Zhang Dong asked.

"I've basically helped you, and there's one last chance to make a move, so you don't want me to help you control the purple-haired old devil, right?" Siki replied lightly.

"I don't need you to do anything. I have my own way. ”

After Zhang Dong finished speaking, he closed his eyes and thought for a while, then gritted his teeth, and carefully read the fonts that had entered his mind from the Great Daohua Hengbao Book again, and communicated with those fonts with such a question.

These fonts were amazing enough to answer questions, and they all answered him, but he was barely able to do so at the moment, but one of them gave him a seemingly feasible answer.

If you want to control an enemy who is many realms higher than your own cultivation, you must cast a more advanced slave seal, and the more advanced slave seal is not Zhang Dong's soul mark - cannon, but Zhang Dong's spirit fetus uses a strange method to combine countless rules of heaven and earth in the way of swallowing, and transforms into a soul dragon according to the way of swallowing! The Soul Dragon is a step further than the Spirit Body Dragon, and it has the magic of God.

His face was full of excitement, and without hesitation, with a movement of his heart, he let countless Swallowing Dao Heaven and Earth Rules come to the Spirit Sea, and then combined with every particle of the Spirit Fetus, and soon turned into a soul dragon that was only as big as a toothpick, forming a shape like a mosquito coil, while the head was erected high, looking like a seal, exuding a mysterious aura and a strong coercion.

"Hahaha......"

Zhang Dong couldn't help but laugh excitedly, and without hesitation, he immediately let the seal formed by the soul dragon drill into the soul devouring bottle, and violently shook it with the secret method, and soon, this slave seal became extremely hot, and the color also became red, and it was fiercely covered on the forehead of the purple-haired old demon who was on guard.

"Sneer......"

A strange sound sounded, and a red light burst out in an instant, turning all the soul bodies of the purple-haired old demon red.

"Ah......h

The purple-haired old demon's soul body let out a terrible scream, and his whole body was trembling constantly, as if he had suffered an unprecedented pain.

Finally, the Slave Seal finished the lid and gently stepped away.

A delicate soul mark naturally appeared on the forehead of the purple-haired old demon's soul body, and this time it did not collapse again, it was extremely stable.

"Ah...... Break my ......"

The purple-haired old demon shouted frantically, and the soul particles on his forehead vibrated rapidly, trying to shatter the slave seal.

However, this slave seal actually had a strange ability, and it sank into it in an instant, swimming in the body of the purple-haired old demon like a swimming fish, and finally entered the heart of the purple-haired old devil, bursting out with a blood-red light, and instantly turning all the soul body of the purple-haired old devil red.

A trace of sadness appeared on the face of the purple-haired old devil, and then the sad color also dissipated, and he became happy, throwing himself to the ground, and shouting respectfully: "The purple-haired man has seen the master, and he will always serve the master." ”

And the slave mark in his heart also returned to normal, and there was no more blood-colored light, and he stayed quietly in his heart.

Zhang Dong's face was full of shock and disbelief, of course, not because his slave seal had such great power, but because there was no immortal immortal immortal immortal emperor in the purple-haired old demon's soul.

Misty was also shocked, stammering, speechless for a long time, Zhang Dong was only the fourth level of the Grandmaster, and he had not found the way of the slave, but he could use such a strange method to control the purple-haired old demon who had cultivated to the ninth level of the Grandmaster? How genius is he? Why is he so magical?

Si Ji, who was on the beauty plate in the medicine garden in Zhang Dong's body, also turned around slightly, with a flower-like smile on her pretty face, and said in an inaudible voice: "Do it yourself, have enough food and clothing, I hope you can always understand this truth, strong, fast and powerful, the same is true." ”

"True Dragon, Soul Dragon, he basically comprehended it, and it was easy to show it, it was a miracle, I hope he can ......" The monitor turned into a white-bearded old man located in a mysterious area of Zhang Dong's mind, laughing so much that his mouth was crooked, and his voice was inaudible.

"Whoosh......"

The soul dragon flew out of the Soul Devouring Bottle and entered Zhang Dong's spiritual sea, and instantly turned into a spirit fetus again.

"Alas......"

Monitor and Silky sighed heavily, almost at the same time.
