Although the demon lord was asking, Zhang Heng knew that he couldn't give a negative answer.

Once the demon lord didn't hear what he wanted to hear, then he was afraid that he would not be able to walk out of the hall alive, so Zhang Heng did not hesitate at all, and his eyes showed a look of determination.

"The demon lord can rest assured, he must refine the Heavenly Soul Melting Blood Pill to repay the demon lord's great kindness!"

The demon lord was very satisfied with this answer, and his eyes softened a lot.

"Very good, you have to remember what you said, in three years, I want to see the results!"

Three years is definitely not a long time, especially for demon beasts, sometimes just a sleep, and then more than ten years pass in a hurry......

"The deity doesn't have that much time anymore, three years, three years at most, I want to see your results, even if you can't refine the Heavenly Soul Blood Melting Pill, at least, I want to see that you are moving in the right direction......" The demon lord took a deep breath and said.

"Why is he so urgent?" A question flashed in Zhang Heng's heart, it stands to reason that the demon lord only survived the Heavenly Tribulation hundreds of years ago, and the next Heavenly Tribulation will be at least hundreds of years later...... Time is abundant, why is he obsessed with seeing results in three years?

"I can guarantee that within three years, I will definitely let the demon lord see hope!"

Zhang Heng suppressed the doubts in his heart, but said firmly.

"The deity is looking forward to you fulfilling your promise, and when you really come up with results, the benefits I promised you will definitely not be missing you. The demon lord looked at Zhang Heng deeply, and after a while, he suddenly stood up, took a step forward, and said majestically.

"From today on, the human race monk Zhang Heng is the demon envoy of the deity, specializing in refining pills, and no one is allowed to go against Zhang Heng's wishes in anything related to alchemy!"

His voice was like thunder, rolling and echoing.

In the outside world, the green python king changed color, and a look of surprise flashed in his eyes.

"You even let this kid be a demon envoy?"

The Yin Hades King, who was rushing back to the cave and was walking halfway, instantly clenched his fists.

"That Heavenly Soul Melting Blood Pill, it is impossible to refine it, I have studied it for a hundred years, and I still have no eyebrows...... Could it be that this Terran boy is enough, why did the demon lord give him so much authority?"

Not only him, but all the demon kings in the demon domain heard the order of the demon lord.

"Demon envoy Zhang Heng!"

They remembered the name, whether it was good or bad, in short, in their minds, suddenly there was an image of one more person.

A look of surprise flashed in Hu Mei'er's eyes, but she didn't show it, but took a step forward and said with a smile.

"I've seen the Emissary. ”

Zhang Heng was stunned and hurriedly surrendered his hand.

The fox concubine called her like this, which made Zai Xia panic. ”

Fox Mei'er waved her hand and said.

"The demon lord is the heaven of the demon realm, and he has appointed you as a demon envoy, so you don't have to be afraid of anyone anymore...... For you, refining the Heavenly Soul Blood Melting Pill is your greatest mission, in this regard, if you have a request, even if you can ask for it now, the demon lord will try his best to meet you. ”

Hearing this, the demon lord nodded and said.

"Yes, if you have any doubts, you can say so. ”

Zhang Heng thought for a while and said.

"Alchemy needs a secluded place, I don't know where my alchemy place is?"

A glint flashed in the demon lord's eyes and he said.

"Nature is in my cave. ”

"But ......" Zhang Heng seemed to have some doubts.

"What's the matter, could it be that you don't want to make alchemy under the nose of the deity?" A trace of suspicion flashed in the demon lord's heart, if this is the case, then it means that Zhang Heng is half-hearted and has other plans.

"Of course not, being able to refine the pill under the supervision of the demon lord is also a great urge...... Zhang Heng hesitated for a while, and said: "It's just that this Heavenly Soul Melting Blood Pill is a top-level elixir, and its refining process is almost unimaginable, and the elixir recorded in the pill is even more complicated, if you want to deduce the correct pill as soon as possible, then I need to test the medicine......"

"Test the medicine?" Fox Mei'er was stunned.

"Exactly, the method of alchemy can be cumbersome, but it cannot be biased, because once there is a small problem in a certain link, it is very likely to affect the whole of the elixir, and even the elixir, and it may become a poisonous pill ......" Zhang Heng arched his hand and said: "For the demon lord's alchemy, you must be cautious and cautious, and you would rather work hard than be negligent, so I will try the elixir recorded on the pill one by one, and use the elimination method to deduce the correct pill!"

"That's a good idea. The demon lord's eyes showed appreciation, he didn't expect that Zhang Heng would come up with his own ideas so quickly, and from his point of view, this idea really has a certain feasibility.

It's just that it sounds like it's become a lot more cumbersome, but as Zhang Heng said, cumbersome also has cumbersome benefits, it's not a big mistake to be careful, the person taking the pill is himself, of course he doesn't want the pill to have any hidden dangers.

"But according to this method, there are two problems, one is that the consumption of elixir is probably much greater. Zhang Heng said hesitantly.

"You don't have to worry about this, three hundred kinds of elixirs, the demon lord has already collected hundreds of them, enough for you to use!"

"With the demon master alone, I'm afraid that I still can't collect so many elixirs, I'm afraid most of them are the old people of the ancient demon domain......" Zhang Heng was shocked by their wealth, he didn't hide his emotions, but after the shock, he showed an unspeakable appearance: "In addition to the consumption of elixir, there is another problem, that is, in the process of testing medicine, there may be some accidents." ”

"Accident?"

The demon lord frowned.

"Yes, the elixir itself can be fused into an elixir, which is a wonderful accident, but it doesn't mean that every fusion can have a wonderful result, it is very likely that some unexpected things will occur......" Zhang Heng said: "Therefore, I suggest going to the caves of other demon kings to refine the elixir, so as not to get too close and cause trouble to the demon lord." ”

"Hahaha, you're overly worried, it's just alchemy, what trouble can it bring to the deity?" The demon lord said nonchalantly: "You just care about alchemy, no matter what accident happens, the deity will not blame you!"

The Heavenly Soul Blood Melting Pill was something he had always dreamed of, and in order for Zhang Heng to refine this pill, he had already paid a lot.

Therefore, of course, he had to put Zhang Heng under his nose to feel at ease, and he would definitely not allow him to go elsewhere for alchemy.

"If that's the case, then there won't be any doubts in the next place, don't worry, the demon lord, I will come up with ......results soon," Zhang Heng said.

"The deity is looking forward to that day...... Now, you can go down and start alchemy as soon as possible. ”

The demon lord waved his hand.

Zhang Heng respectfully stepped back and looked at his back, the eyes of the demon lord suddenly became gloomy.

"The demon lord is not at ease?" asked Hu Mei'er when she saw the demon lord's expression.

"He's just an ant in the Jindan period, what's so worrying about the deity? If he dares not to do his best, the deity can pinch him to death at any time......" The demon lord put his arm around the fox Mei'er, but sighed: "What I'm really worried about is whether he can give me hope in the past three years." ”

"If there is no hope, I can only vent my anger if I kill him, and in the end, I will get nothing. ”

Fox Mei'er said quietly.

"This person has broken the seven levels to the extreme, and in terms of alchemy attainments, he is superior to the Tianjiao of the ancient period, if he can't refine the Heavenly Soul Blood Melting Pill, I'm afraid that no one in the world will be able to succeed...... The demon lord has given him so many benefits, presumably he has already bet on him, since he has made a bet, let's not think so much about it...... If even he can't refine it, then perhaps, this is the will of heaven. ”

The demon lord was silent for a long time and said lightly.

"Even if it's really providential, I won't accept my fate easily...... Tell the Python King, let her keep an eye on this kid at all times, if he has any requests, try to meet them, and if he has any misdeeds, take him down immediately!"

Fox Mei'er nodded.

And at this moment, Zhang Heng, who had already walked out of the Demon Lord's Palace, had a sneer in his heart.

"I've warned you, but you're still going to keep me here, so I hope you don't regret it!"

The Heavenly Soul Melting Blood Pill, he really hadn't come into contact with it, but with Zhang Heng's attainments, if he wanted to go all out to refine the Dan formula, why bother so much? At most, he could complete the deduction in one year.

However, he is not stupid and will not really do things for the demon organizer wholeheartedly.

Therefore, the process of alchemy will definitely not be smooth, even if there is no accident, he will have an accident!

Only in this way can he have a glimmer of possibility of escaping!
