With such a temperament as the Yin Hades King, it was absolutely impossible to say the word admiration to Zhang Heng, and when he found that his Dan Dao attainments were really inferior to Zhang Heng, the jealousy in his heart suddenly magnified several times.

"Eldest sister, this kid must not stay!"

The Netherworld King transmitted, and his tone was full of murderous intent.

The Green Python King knew why the Hades King suddenly doubled his killing intent, it was nothing more than jealousy, to be honest, she didn't like this kind of character, if it was in normal times, maybe she would have to reprimand him, but at this moment, she nodded slightly and replied.

"Of course, when Dancheng is completed, it is when he loses his life!"

In the eyes of the two, Zhang Heng has been immersed in alchemy at the moment, but in fact, he has reserved a lot of energy, paying attention to the two, and naturally seeing their "eyebrows", Zhang Heng sneered in his heart.

"Do you really think I'm the meat on your chopping board? It's not that easy to kill me!"

He pinched the seal and kneaded a lot of elixirs that had melted into liquid into a ball, and threw them into the Dan furnace.

"If you want to escape from the demon domain, it must be a very dangerous thing, leaving from the demon lord's side is only the first step......" Zhang Heng took a deep breath, the original vague plan was becoming clearer and clearer at the moment!

The Dan Fang of the Heavenly Soul Melting Blood Pill, he has completely deduced it, and he is ninety percent sure that he will refine the Heavenly Soul Melting Blood Melting Pill.

At this moment, he was refining step by step according to the Dan formula.

The Yin Hades King, who was bent on picking thorns, couldn't see any flaws at all, but had a feeling of being sudden, in the past, he had also studied Danfang, but he had no clue, and now when he looked at Zhang Heng's alchemy, he had a feeling of seeing through the clouds.

"This kid is really stupid, originally I thought he was still a little scheming, but I didn't expect that now he is really refining the Heavenly Soul Blood Melting Pill with his heart, doesn't he know that when the Dan is completed, it will be his death......" The Yin Hades King sneered in his heart, his eyes full of mockery.

In his opinion, what if Zhang Heng was an alchemy master? It was not a dead end, after all, he could only make a wedding dress for the demon master.

"It seems that he has already believed that I am concentrating on refining the Heavenly Soul Blood Melting Pill. ”

Zhang Heng felt the change in the eyes of the Yin Hades King and knew that the time was ripe.

The seal in his hand was mutated, and several rays of multicolored light entered the Dan furnace.

If it had been placed before, the Netherworld King would definitely have asked, but after Zhang Heng's beating, coupled with the fact that he was impressed by Zhang Heng's Dan Dao during this time, he did not have any doubts.

Because of more than this hand, he couldn't understand many of Zhang Heng's techniques before, but after thinking about it, he felt extremely profound.

In fact, this handprint is Zhang Heng's reserved backhand.

Even if the pill is completed, as long as his heart moves, the pill will be shattered in an instant!

This was one of the preparations he had made, in case he couldn't escape, then he wouldn't let the demon lord get the Heavenly Soul Melting Blood Pill......

"In any case, let's refine the Heavenly Soul Blood Melting Pill first!"

Zhang Heng took a deep breath, stopped paying attention to the two of them, and really began to refine the pill wholeheartedly.

The grade of the Heavenly Soul Blood Melting Pill is very high, plus the elixirs used are all top-notch, and the difficulty of refining is extremely high, if it weren't for the fact that Zhang Heng had just broken through to the middle stage of the Golden Pill not long ago, I am afraid that it would be even more difficult to refine, but even if he broke through now, he also needed to be cautious, and if he was negligent, it was likely that the pill would really be ruined.

Zhang Heng's divine thoughts poured into the Dan furnace, and the flames and the various changes produced after the fusion of the medicinal liquid were all reflected in his mind.

His divine thoughts were like spider webs, spreading out in wisps, controlling every drop of the medicine, even the slightest insignificant reaction, was also in his control.

This process lasted for two months, and finally, in the Dan furnace, a mass of liquid wrapped in the cold fire of the Netherworld was formed, about the size of a fist, with ripples of color, exuding a stream of red blood.

Zhang Heng breathed a sigh of relief, the most difficult step had been completed, the liquid medicine had been completely stabilized, and next, he only needed to control the heat and smelt the liquid medicine to turn it into a prototype of the elixir.

This process took another ten days.

During this period, the Green Python King and the Yin Hades King have been guarding on the side, the Green Python King is better, but he is just closing his eyes to recuperate, while the Yin Hades King, like Zhang Heng, is nervously paying attention to the changes in the medicinal liquid.

After all, for him, whether Zhang Heng succeeds or not has a direct relationship with whether he can get the cold night fruit.

"It seems that the most difficult step has passed, maybe this time, he can really refine the Heavenly Soul Blood Melting Pill......" The Yin Hades King looked at Zhang Heng Gujing Wubo's face, these days, he watched Zhang Heng refine the pill, and he really gained a lot, and because of this, he felt even more ashamed, a small role that he didn't put in his eyes at all, actually surpassed him completely in some aspects.

Thankfully, this kid is destined to die!

Ten days later, in the early morning, Zhang Heng slowly opened his eyes.

There was a dizzying sheen in his dark eyes, like a plain grain of sand that suddenly turned into a dazzling gold.

Even the Green Python King opened his eyes and looked at him in surprise.

It was the first time she had seen Zhang Heng with such a demeanor.

In the Dan furnace, the fist-sized liquid medicine had completely melted and turned into an uneven pill rudiment.

Although this elixir is still only in an embryonic state, it exudes a strange aura.

"It's become a ......," Zhang Heng muttered in his heart.

The success of refining the elixir this time was really a bit of a fluke for him.

Although in the eyes of the Green Python King and the Yin Hades King, he seemed to have always been in a state of ease, but in fact, Zhang Heng knew that the refining of this Heavenly Soul Melting Blood Pill was extremely complicated, and even the slightest mistake on his part would lead to a loss of the whole game.

Simply, he persevered and finally succeeded.

This also has a lot to do with the Netherworld Cold Fire, this kind of cold flame can not only control the temperature of the furnace, but also allow the alchemist to always be in a calm state.

"One last step, warmth!"

Zhang Heng pinched the seal and shot out hundreds of colorful rays of light in one go.

When all this was done, he closed the lid and sat cross-legged.

Next, he only needed to control the temperature, and when the pill changed from an uneven appearance to a mellow appearance, it would mean that he had refined the Heavenly Soul Blood Melting Pill.

"Unexpectedly, he actually succeeded!"

The Netherworld King Rao had already guessed, but when this day really came, he was still shocked.

Even the Heavenly Soul Blood Melting Pill, which even the ancient alchemy masters were helpless, was successfully refined in Zhang Heng's hands.

"He's become?"

The Green Python King was a little stunned.

In her mind, this time, even if Zhang Heng didn't sabotage, then he wouldn't sincerely alchemy for the demon lord.

Because Zhang Heng is a smart person, since he is a smart person, he naturally knows his situation.

But who would have thought that he would actually refine the Heavenly Soul Blood Melting Pill!

Could it be that everything before was a misunderstanding, and he was really doing things wholeheartedly for the demon lord?

All of a sudden, the green python king turned out to be a little messy.

"It's basically done, and the next step is to recuperate, and this step rarely goes ......wrong," said the Netherworld.

The last step of recuperation lasted for three months.

For three months, whether it was Zhang Heng who was alchemizing or the two onlookers, there was no impatience at all.

It is even said that the Yin Hades King and the Green Python King are always in a state of excitement, if the demon lord gets the Heavenly Soul Melting Blood Pill and his strength is greatly improved, then it is also great news for the entire demon domain......

On this day, a wisp of medicinal incense floated out.

Just by smelling the fragrance, the two demon kings were shocked, and a sense of longing poured out of their blood.

The Heavenly Soul Blood Melting Pill is not only useful for the demon lord, but also for the entire demon clan, it is a rare good thing.

Zhang Heng got up, patted his palm, and opened the lid of the furnace.

A purple and red pill is suspended in the pill furnace, and the magic is that just above the pill, there is a gap, just like a human eye, blinking and blinking, every time it blinks, there is heaven and earth aura devoured by it!

"It's done!"

"This is the legendary Heavenly Soul Blood Melting Pill?"

When the two demon kings saw this scene, their eyes showed greed at the same time, this is not to say that they dare to rob the demon lord's things, but as demon clans, they instinctively have a possessive desire for this elixir.

"Don't rejoice too soon. ”

Zhang Heng said lightly.

"Let's get through the tribulation first. ”

The green python king was stunned and didn't understand.

But the Netherworld King stiffened, and he suddenly thought of something, and his face suddenly turned pale.

"You mean the Dan Tribulation, there will be a Dan Tribulation with Dan Thunder!?"
