"From today onwards, I will stay outside the Medicine Palace. The Green Python King looked at Zhang Heng, and a hint of indifference flashed in his blue pupils: "If the demon envoy has any requests, you can leave it to me...... This time, I'm going to do my best!"

The green python king was not punished by the demon master, but in her heart, she was holding back a breath.

Because, Zhang Heng, the initiator, was also not punished, but also benefited.

Especially since she always had an inexplicable premonition, as if all this that happened seemed to be expected by Zhang Heng...... Although there is no evidence, the green python king trusts his instincts very much.

Therefore, she decided that she would not practice at all, and would guard Zhang Heng for three years, staring at his every move!

"The Green Python King is polite...... Zhang Heng said, paused, and showed hesitation: "Or, are you giving me a batch of beasts for me to test the medicine?"

The corners of the green python king's eyes twitched.

How dare you test the beast?

The last time I tried the medicine, it made a mess of the demon lord's cave, and people turned over on their backs, and I had to pay it back again?

The most important thing is that this chaos has nothing to do with her, strictly speaking, it was her dereliction of duty by the King of Green Python and did not take Zhang Heng's words to heart, which caused such a incident.

This matter is the scale in her heart, and it is also her shadow.

"There's no need to test the medicine!" the green python king refused without hesitation, and there was a faint evil in his eyes.

Zhang Heng didn't want to stimulate her too much, just pretended to be sorry and sighed, then arched his hand at her and entered the medicine hall.

Looking at his back, the eyes of the green python king were full of chills.

In the medicine hall, Zhang Heng sat cross-legged.

In his palm were three storage rings, which contained elixirs from the demon lord's reward, which was a windfall for him.

Originally, what he thought in his heart was that it was enough not to be punished by the demon master, but he didn't expect that the demon lord would surprise him.

"The more this is the case, the more it shows that the demon lord attaches great importance to the Heavenly Soul Melting Blood Pill......" Zhang Heng's eyes showed a look of thought: "Because of this, even if I make such a big mess, he is still reluctant to put me elsewhere, because only under his nose can he really rest assured." ”

"However, if I want to be free, I must keep a certain distance from him, and only in this way can I have a chance to get out of his control!"

"So, I definitely can't settle down, I'm going to make a bigger mess, I'm going to make him unbearable with me and send me out!"

Zhang Heng took a deep breath, his plan had been set from the beginning, but at this moment, his thinking became clearer and clearer.

The outside world doesn't know what's going on, but according to the time, I'm afraid the others have already left Hengwu Cave.

But he's trapped here!

It is precisely because of this that Zhang Heng has a greater sense of urgency in his heart, Hengwu Dongtian is an independent space after all, and this place has its own rules, for example, when to leave this space, there is already a fixed number.

And if he misses this time, how can he leave?

Even if he escapes from the Demon Lord Cave Mansion, he may not be able to leave this space and return to Dongzhou......

This is almost unpredictable.

But Zhang Heng had to gamble, because staying here was a companion like a tiger, and the demon lord was hypocritical to him, and the demon kings couldn't wait to eat him in one bite...... No matter whether he can refine the Heavenly Soul Blood Melting Pill or not, it is a dead end!

"This Heavenly Soul Melting Blood Pill is a very good pill, and I have already deduced half of it...... The effect of this pill, as the demon lord said, can purify the bloodline...... If I can escape, I can sweep away these elixirs together, refine the elixir, and cultivate spirit beasts!"

Zhang Heng seemed to have low eyebrows and pleasing eyes, but in fact, there were many dangerous thoughts brewing in his heart.

The medicine boys stood around respectfully, not daring to disturb him.

They were more in awe than before.

"The master is really amazing, the pill that was refined casually actually made the beast riot......"

"Yes, he's a great alchemist. ”

"It's also dangerous......"

The medicine boys exchanged in a low voice, their eyes were full of curiosity, with their Dan Dao attainments, they couldn't learn anything from Zhang Heng's alchemy process, but they could feel the mastery of Zhang Heng's methods.

"Ready, open the furnace for alchemy!"

Suddenly, Zhang Heng spoke.

He looked around at the medicine boys and said.

"Tell the Green Python King, get me a hundred elixirs!"

"Yes, sir. A medicine boy hurried out.

"A hundred?"

The Green Python King frowned, the Heavenly Soul Blood Melting Pill needed three hundred kinds of elixirs, and these elixirs were all rare, and their value was very expensive, but the demon lord had collected hundreds of copies of each, so you can imagine how much hard work he had spent!

There are many of them, all of them are the old foundations of the demon domain in ancient times.

But now, he has to take out a hundred copies for Zhang Heng to squander, the demon lord is not distressed, and the green python king is distressed.

"Wait, the elixir will be delivered in a moment!"

The Green Python King pondered for a while, but decided to obey.

The demon lord has a word first, everything related to alchemy must be listened to Zhang Heng's orders, she has no reason to stop Zhang Heng, but the feeling of Zhang Heng in her heart is even worse.

But she didn't know that with her temperament, if she didn't like a person, then no matter what that person did, she would have a sense of disgust.

Even if Zhang Heng is honest and doesn't do anything, it will still make her angry.

In a short time, a hundred elixirs arrived.

With a wave of Zhang Heng's palm, three hundred Dan furnaces opened fire at the same time, and he once began to refine Dan.

While the medicine boys assisted him, they were also monitoring, but Zhang Heng's Dan Dao attainments were so high, smooth and smooth, the medicine boys who watched it were fascinated, and he was even quieter, so he secretly hid thirty elixirs, which was considered to be a personal filling, but no one knew.

Zhang Heng's alchemy journey was still in full swing, and the Green Python King was ruthless, with a team of demon soldiers, stationed at the gate of the Medicine Palace.

She also has perseverance, and would rather not do anything for three years and just stare at Zhang Heng.

Three months have passed in a hurry, and there has been no movement in the medicine hall.

And at this moment, a burnt smell suddenly came out of the Dan furnace.

"Master, the pill seems to be burnt?"

"Is it too hot?"

"Are all the pills destroyed?"

The medicine boys changed color one after another, and they found that among the three hundred Dan furnaces, there was actually a black mist.

This black fog is a little choking, as if the cooking has been burned.

"The pill is not destroyed, I am still testing the medicine, this is some of the pharmacology conflict......" Zhang Heng was very calm, he waved his palm, three hundred furnace lids flew up, he commanded the medicine boy, and even added a lot of elixir to it.

"The black mist indicates that there is a reaction, and a reaction is a great good thing, which means that these elixirs I tested are either compatible with each other or repelled ......"

"You don't have to panic, open the doors and windows and let out all the black fog. ”

The medicine boys nodded as if they didn't understand, they obeyed Zhang Heng's instructions, opened the doors and windows, and used fans to blow the wind out.

"What's that?"

Outside the medicine hall, a black mist filled out, but it attracted the attention of the demon soldiers.

"It's coming!"

The green python king was not only not surprised, but had a sense of joy that had finally arrived.

Because of her, she had long expected that Zhang Heng would not give in so simply, and he would definitely make a new move.

"This time, I'll be staring at you, I'm going to see what else you can make a name for yourself under my gaze?"

The green python king stretched out his hand and caught a wisp of black mist.

But I didn't find anything strange, except for some pungent and choking people......

"Could it be that the alchemy is scorched?" the Demon Soldier Commander asked suspiciously.

"It's not that simple. "The Green Python King believed in his intuition, this black fog definitely did not indicate that it was so harmless.

There was a thoughtful look in her eyes, but she stared at the black mist.

The mist surged upwards and gradually rose into the air, but it left the Demon Lord's Cave Mansion.

"Follow along. ”

The green python king's expression moved, and he chased after him with a few demon soldiers.

The black fog continued to rise, and after leaving the Demon Lord Cave, it encountered water, but it did not blend with the river, let alone be diluted like this, but still continued to rise into the air, and finally, left the river, rose in a curling manner, entered the sky, and disappeared.

"What is the name in this black fog?"

The eyes of the green python king were full of vigilance, and she simply stopped moving, and stood on the surface of the river.

This stop is a full seven days.

Seven days later, suddenly the sky was overcast with rain and a clattering landing.

"I see!"

A smile appeared at the corner of the green python king's mouth, he thought he had seen Zhang Heng's little trick!
