Pick up a tempering pill, the size of the pill is like the belly of the thumb, the color is dark purple and almost black, although it is only a pill, but it also exudes a strong medicinal fragrance.

Mu Yun divided the Tempering Pill into groups of five, and each group was filled with a porcelain bottle that had been prepared earlier.

No matter how many pins of the pill is, as long as the pill is formed, it must be contained in a porcelain bottle or a jade bottle, otherwise the medicinal power will be dissipated, and it will not take long to become a useless ball of earth.

Without any hesitation, Mu Yun directly took the tempering pill, this was the first time he had taken the system pill, and he was still looking forward to it.

"Don't say it, it's quite a bullet!" Mu Yun's first feeling was like this.

But immediately, the tempering pill turned into a clear stream and entered the body, and immediately continued to swim in the eight veins of the Qi Sutra.

"That's it?" Mu Yun was a little disappointed, after all, after seeing the Healing Pill, Mu Yun was still very curious about the effect of the Tempering Pill.

"It's really uninteresting...... Ahh

Mu Yun only said half of his words, and only felt that his lower abdomen seemed to be punched hard, and this punch weighed 2,500 catties, that is, the strength of five brute bulls. Where could Mu Yun stand it, and suddenly sat on the ground, his face pale.

But before I could react, the same punch was thrown to the inner thigh!

"Ahh

Every part of Mu Yun's body was closely cared for, and his fists were fisted to the flesh, and this situation could not be avoided, because this feeling of boxing was caused by the tempering pill in the body.

"!"

"This Alchemy Pill is poisonous!"

"Stop, stop!"

But no matter how Mu Yun manipulated the true element in his body, the medicinal effect of the tempering pill still existed, and the strength of each punch was still increasing.

System: "Each time you take the Alchemy Pill lasts for two hours, and the host or the user cannot change it. ”

"Your sister, you're taking revenge on me, why didn't you tell me in advance!"

System: "You didn't ask!"

"Bang! bang!"

"Ahh

......

Two hours later, Mu Yun rolled his eyes and lay on the ground foaming at the mouth.

"The elixir that pits the dead father!

Although Mu Yun didn't have any external injuries now, his muscles were extremely sore, which was very similar to the way he exercised his muscles in his previous life, except that this kind of strength was greater and more unbearable.

System: "The heavens will descend on the people, and the people must first suffer their minds......"

Mu Yun: "While I'm not angry, get out!"

System: "Okay!"

Although the method of tempering the body is a bit violent, when Mu Yun rested all night, his waist was not sore, his legs did not hurt, and it was not difficult to go up to the fifth floor in one breath, and even his muscles were condensed a lot!

"Is it so amazing?" Mu Yun said in surprise.

With a wave of his hand, he clearly felt the increase in strength, and it seemed to be as much as 100 catties.

"Beating can increase the strength of 100 catties!" Mu Yun immediately put the beating behind him, and stared at the porcelain bottle containing the tempering pill with bright eyes.

Go ahead decisively!

But this time, Mu Yun had a heart and wanted to eat two at a time, so that he might be able to reap double the effect. And at this time, the voice of the system appeared.

System: "Please note that the Tempering Pill will be analyzed according to the user's cultivation and qualifications, and taking two pills is invalid. ”

Mu Yun raised his eyebrows, and he could only take one again, after two difficult hours, Mu Yun had only rested for three hours this time and had recovered, and his muscles were stronger and his strength was increasing.

Holding the tempering pill in his hand, Mu Yun's face was already full of joy.

"It's going to be developed! it's going to be developed!" Mu Yun said silently.

This kind of elixir is not to mention Tianmang County, even the Southern Heaven Realm may not have it, it directly increases muscle and strength, and if you release it, you won't grab it!

After calculating the number of existing disciples, Mu Yun divided the pills, and finally left ten pills, ready to take them to Tianmang County to try his luck.

Just as he was about to call Du Yuanwu over to distribute the tempering pill to his disciples, a strange idea suddenly appeared in Mu Yun's mind.

Random Mu Yun entered the mind space, took out the magic bottle, held the magic bottle in his hand, Mu Yun's mind flashed Du Yuanwu's figure, and the corner of his mouth showed a smile similar to that of a devil.

"Don't blame me, junior brother, I can't help it! I can't experiment with myself!" Mu Yun said in his heart.

But he actually knew that the demonization bottle would not hurt Du Yuanwu, at most, it would be uncomfortable for a few days.

Du Yuanwu was sitting cross-legged to absorb his breath, and suddenly sneezed, and a cold feeling suddenly rose behind him.

At this moment, a disciple said outside the door: "Master Du, the head of the sect has asked you to go to the main hall and say that there is something important to discuss." ”

When Du Yuanwu heard this, he didn't hesitate and got up and went to the main hall. Originally, every time I went, I didn't feel anything, but this time there was always an eerie feeling.

Slowly pushing open the door, Du Yuanwu looked inside, and saw Mu Yun sitting on the seat of the head of the gate, looking down at his hand, and he seemed to be holding something in his hand.

Suddenly, Mu Yun looked up at him, and a wicked smile flashed on his face.

"Senior Brother Du, you're here!Come in!" Mu Yun said.

Although Du Yuanwu was a little puzzled, he still pushed the door and walked in and sat down next to Mu Yun's subordinates.

Mu Yun picked up a bowl of water from the side, held the demonized tempering pill in his hand, slowly walked towards Du Yuanwu, and said, "Da Lang, it's time to take medicine!"

Du Yuanwu struggled and said, "Wait for my brother Wu Song to come back......"

The above, in fact, no, this is all Mu Yun's imagination! Du Yuanwu very happily ate the Demon Tempering Pill.

"What kind of elixir is this, master!" Du Yuanwu asked.

"Smack!"

Mu Yun snapped his fingers with a smile and said, "You'll know in a while!"

Before Mu Yun's words fell, Du Yuanwu began to tremble, and a miserable scream came from his mouth.

"Poof!poof!"

"Ahh

Mu Yun listened to this voice, like beautiful music, and shook his head unconsciously.

At this time, on the square of the main hall, two disciples passed by, and suddenly heard Du Yuanwu's screams, and just wanted to go over to ask, but suddenly found Mu Yun shaking his head happily from the window, and immediately fled in panic.

"It's terrible! It's terrible! The head of the sect has such a hobby!" said one of the disciples.

Mu Yun's thoughts of those two disciples were naturally unknown, but now he was very worried about Du Yuanwu, because it had been three and a half hours, that is, seven hours, since he had taken the tempering pill.

They all rolled their eyes and didn't move, Mu Yun was a little panicked, after all, the demon didn't know what the situation was.

Just when Mu Yun was about to go over to see what was going on with Du Yuanwu, a stream of aura gathered from all directions, and the center was Du Yuanwu, and the aura converged into a pillar of blue light that was a foot wide and injected into Du Yuanwu's body.

This aura lasted for half an hour before it stopped, and the moment it stopped, Du Yuanwu suddenly opened his eyes, his eyes were shining, and a cold aura gushed out of his body, which turned out to be a sign of breaking through.

"Ahh

Du Yuanwu shouted violently, and a cold air suddenly hit the four directions, Mu Yun suddenly supported Zhenyuan to block himself, and the other directions in the main hall were exposed to the cold, and a layer of frost suddenly appeared.

"Sudden ...... Breakthrough?" Mu Yun stammered.

Mu Yun's chest suddenly felt as if he had been hit by a 10,000-ton boulder, and he was about to commit a heart attack, he made a mistake, and wanted Du Yuanwu to try the magic bottle for himself, but he didn't expect that this time it was a real enhancement.

"Master, what kind of elixir is this, it's just too strong! Thank you for the medicine!" Du Yuanwu said excitedly.

Mu Yun's mouth and face twitched unconsciously, he only had infinite regret in his heart now, why didn't he grit his teeth and swallow it directly! Why did he have to find Du Yuanwu to do an experiment, this was really a loss to his wife and soldiers!

"Of course this is the reward of this throne. Mu Yun said stiffly.

But then Mu Yun was relieved, after all, Du Yuanwu was also an elder of the Northern Xuan Sect, and if he was strong, it naturally meant that the Northern Xuan Sect was strong, and it also proved that the Demon Bottle did have an enhanced function, and this function was extremely good.

"You go find a blade, preferably stronger. Mu Yun said.

Although Du Yuanwu didn't understand what the head of the sect was going to do, he still went to look for it immediately, but the Northern Xuan Sect was so shabby that he couldn't even find a decent blade, and finally only found a long sword that was not in the grade.

Mu Yun looked at the unqualified long sword and sighed, but still took out the magic bottle and dripped a drop of purple magic liquid on the long sword.

The demonic liquid quickly merged into the long sword, and the long sword suddenly shook violently, and a seemingly nonexistent blue light slashed across the sword's body, leaving a scratch visible to the naked eye.

After about a quarter of an hour, the blue light disappeared, and the original long sword body was covered with patterns, and it still emitted a faint light.

Mu Yun held the long sword Zhenyuan and injected it into it, and with a wave of his hand, a cold ice sword qi shot out, directly freezing the door of the main hall and turning it into a large ice sculpture.

"This ...... This...... How is this possible!"

Now Du Yuanwu on the side was already stunned, this was beyond his imagination, if this sword was originally a treasure, but it would not be surprising, but this sword was found by him, and only half an hour ago, he was still a non-quality blade without any lethality at all.

But in Mu Yun's hands for a while, he actually had such power.

Not to mention Du Yuanwu, even Mu Yun was stunned, although the magic bottle was his, it was the first time he felt such a terrible change.

"Ding!"

"The host has used the Demonization Vial twice, and the Demonization Vial has gone into cooling. Cooldown: 24 hours. ”

Mu Yun listened to the sound of the system, it turned out that the use of the magic bottle was limited, and it could only be used twice a day at most.

casually threw the demonized long sword to Du Yuanwu, after all, his true yuan was the ice attribute, and with the addition of the ice sword, it was even more powerful.

And Du Yuanwu couldn't believe that Mu Yun gave him this treasure, happily stroked the cold ice sword repeatedly, and said: "Since you are given by the master, let you kill the cold!"

Three black lines suddenly rose on Mu Yun's head, "This name has something to do with me!"

"Ding!"

"Side quest: Fight with Qin Huai and protect Du Yuanwu. Reward: 30 Sect Contribution Points. ”

The sound of the system sounded in his ears, Mu Yun frowned, and looked at the bright moon outside the window, under the bright moon, several killers were constantly walking through the shadows.
