It's just a chapter with a recipe for a certain recipe.

But it exuded a peculiar medicinal fragrance, which surprised both Chen Qi and Sheng Xueqin.

"Shhhh

At this moment, the old man grabbed it lightly with his skeletal fingers, and saw that those ancient symbols had gathered together and turned into a black thing.

The black slimy thing seemed to be moving, and the wooden material was holding it underneath, and the green flames suddenly became even hotter, as if it had burned those ancient symbols into this black slimy thing.

It was like a living thing, like a worm crawling, like some evil spirit coming out of it, and like a stream flowing slowly.

All in all, in the eyes of Chen Qi and Sheng Xueqin, this is really weird.

At this time.

Chen Yuan closed his eyes, exhaled deeply, and muttered: "Turtle Grass, Divine Water, Chen Ghost Heart......"

He said one name after another, these names Chen Qi and Sheng Xueqin had never heard of, although it sounded like the names of some spirit grasses, but the two did not know each other at all.

And the old man on the side read out the names one by one with Chen Yuan, and his emperor's head seemed to be listening to whether Chen Yuan was wrong.

After Chen Yuan recited a long list of names, in the end, he suddenly looked at the old man with emotion: "Your underworld recipe is already complete, why do you still say that you want me to let me match it again?"

The old man said slowly: "I feel the breath on your body, then you should also know that this underworld cannot be complete, after that realm was broken, this underworld will not be complete." ”

"Of course, this underworld formula should be the same as the underworld formula you know, and you don't need to adjust it anymore, but I need you to handle it and make this underworld formula, which I can't do, my breath no longer belongs to this world. ”

After hearing the old man's words, Chen Yuan's expression was solemn.

He knew that the origin of this underworld was from the underworld, and it was one of the most special underworld prescriptions in the underworld, and the origin was very amazing.

"I don't necessarily have it. ”

Chen Yuan sighed lightly.

He knew this recipe from the sword spirit, and he also had the spirit qi, but he might not necessarily be able to succeed.

Sheng Xueqin, who knew Chen Yuan, couldn't help but be moved when she heard this, she knew Chen Yuan better than others, and this was the first time she had seen Chen Yuan say such unconfident words.

Ever since she had known Chen Yuan, nothing seemed to be able to hold him back.

What exactly is this recipe?

"You can, if you can't do it, then no one in all directions can do it at the moment, and I can only continue to wait. ”

"And this formula, even if it can succeed so far, is only the first stage, but it is enough for me, I don't need the most complete stage. ”

The old man said slowly.

At this time.

A twilight scene appeared in Chen Yuan's mind, these were all left by the sword spirit.

It was the scene of the underworld refining this underworld eons ago.

Time passed moment by moment, and before he knew it, Chen Yuan was already sweating profusely, and sweat the size of a soybean was dripping down his cheeks.

It didn't take long for Chen Yuan's whole body to be soaked with sweat.

He looked like he had been fished out of the water, and his breathing was getting thicker and thicker.

At this time, Chen Qi and Sheng Xueqin couldn't help but be a little worried.

At this time.

Countless scenarios and the use of medicinal herbs matched in Chen Yuan's mind.

You know, this is not difficult for Chen Yuan.

The underworld, one of the Nine Realms, had disappeared before eons, and the elixirs that still existed in various interfaces were very rare, and even Chen Yuan in the previous life had hardly used the elixir when he was refining.

As for the underworld, even the simplest underworld formula, Chen Yuan had never tried to refine it.

And this is the first time, to refine one of the most difficult underworld recipes in the underworld, Chen Yuan must be cautious.

With the countless experiences left by the sword spirit, in fact, Chen Yuan was already far ahead of everyone else.

Today, he is doing everything he can to match this ancient recipe that has always been legendary.

According to the Sword Spirit, even when the Nine Realms were not broken, this underworld recipe was one of the ten most difficult formulas in the Nine Realms when it was complete.

Although this time it is only to be refined into the first stage, it is still amazing enough.

"Damn. ”

I don't know how long it took, Chen Yuan couldn't help but scream, and sat directly on the ground.

"Childe, are you alright?"

Sheng Xueqin hurriedly stepped forward, and Chen Qi also felt that he came up and asked.

Chen Yuan exhaled a long breath, as if he was suffocating just now.

Although his current cultivation is not low, it must be low compared to refining this underworld, even if he is just studying it in his mind, the spiritual power consumed is extremely amazing, even a saint can't withstand it for a moment.

Chen Yuan waved his hand lightly at this time, which made Chen Qi and Sheng Xueqin breathe a sigh of relief, and Sheng Xueqin hurriedly stepped forward to wipe his sweat.

After a while, Chen Yuan stood up, looked at the old man and said: "The first stage of this underworld formula, I can try it, but just try, and I can only make all the proportions the most complete I think, because no one has the most complete underworld formula, and many things can't be determined, and in the end it is the result you want, I'm not sure." ”

"Yes. ”

The old man looked at Chen Yuan for a long time, and finally nodded stiffly and slowly.

After resting for a while, Chen Yuan regained his spirits, he looked at the old man and said, "But you should also know that a heavenly sacrifice dog is not enough. ”

"That sacrifice is not counted in it, it is considered an extra gift from me. ”

The old man said slowly: "You can mention the conditions, or anything here, you can take it with you." ”

As soon as the old man's words came out, Sheng Xueqin and Chen Qi were both moved.

In this space, there are countless heavy treasures, and they even feel the magic weapon aura that far exceeds that of the True Saint Soldiers, it can be said that anything that circulates in the entire space can make all the top forces in the entire Nine Domains break their heads and blood, and can even change the pattern of the entire Nine Domains.

Chen Yuan's eyes narrowed slightly, looked at the old man, and finally said calmly: "I don't want anything here, but I want you to owe me a favor." ”

After hearing such words, the old man's eyes opened slightly, and the green light flashed in his eyes, he stared at Chen Yuan, and did not agree immediately.

After a long time, the old man stared at Chen Yuan, and finally said: "As long as you can succeed in the first stage, I promise you that I owe you a favor." ”
