All the half-demons looked at Hao Yan in amazement, as if they couldn't believe that he could comprehend the Qingling Hundred Herbs Sutra in two hours!

"Boom ——!"

Qinglu's eyes flickered, as if he was responding to Haoyan's request.

"What, you actually want me to refine a Yuan Pill above the top grade of the Great World now?"

Hao Yan understood the meaning of the Qinglu, and the other party actually asked him to practice a medicine with the technique of the Qingling Hundred Herbs Sutra as a proof that he had completely mastered the Qingling Hundred Herbs Sutra.

The world-level top grade is the level required by this Qinglu.

In order to intuitively measure the value of these treasures, cultivators have created a set of simple hierarchical rules, including all things in the world, such as Yuan Wu, Yuan Medicine, and all kinds of utensils, from the mortal level, to the Great World level, and then to the rare world...... Each level is divided into six grades: middle and upper, and Yijishen.

Mortal-level can generally be refined in ordinary small realms, just like Nahua Shuyao, who is a mortal-level Yuan Medicine Master, which is enough to refine a mortal-level middle-grade Yuan Medicine.

And the great world level that Qinglu requires can generally only be seen in the Great Domain.

However, it is not that this Qinglu is difficult, the vitality of the medicine garden here is gathered, and no one has picked it for thousands of years, and the level of the spirit grass bred in it has already reached the great world level, and it is more than enough to refine the great world level of yuan medicine.

As for the required grade, it must be of the highest grade.

This may be a test for the descendants of the Lu family, who have never been exposed to refining medicines, after all, the threshold of the upper grade is to exert the medicinal power of all refining drugs to eighty percent.

But for Haoyan, it's just a joke-

"The world-class high-grade, you look down on me too much!" Hao Yan was very arrogant, sat up directly, and went into the forest to search for materials.

The demons of the Arashiyama Hall looked at each other, not knowing what to do for a while.

Now that Hao Yan has understood the Qingling Hundred Herbs Sutra, then there is really no need for the remaining half-demons who have no understanding to toss on it, so the demons got up one after another from the plate and sat down, followed Hao Yan forward, and saw if there was anything that could help.

"You, go and pull out the red flower over there, loosen the soil and uproot it, and try not to tear off the roots!"

"You go over there, do you see that orchid? I want the juice of the orchid core, you just use an orchid leaf to fill the juice, don't touch the juice with your hands, and don't spill the juice!"

"Someone else there! The red fruit hanging on it, all the red fruit on it, all of them will be taken down for me!"

Since there is a group of helpers following him, of course, Hao Yan is implementing the principle of not doing anything if he can, leaving everything to these half-demons to do, and helping him collect all kinds of spirit flowers, spirit grasses, and spirit fruits.

The time of the half-burnt incense passed, and Hao Yan led these half-demons to visit this small forest medicine garden, and at this time, the half-demons were more or less holding a few rare materials in their hands.

"Put it all here, lightly, be careful not to spill it!"

At this time, everyone returned to Qinglu, and the demons put the collected spirit grass and spirit fruits on the ground lightly, and Hao Yan also sat on the ground with his ass in his head, and his vitality was circulating, ready to start refining the big medicine!

The demons looked at each other, and they didn't know if Hao Yan was talking big.

After all, all the demons had just comprehended the Qingling Hundred Herbs Sutra, and they had all felt the complexity of this set of medicinal scriptures.

Qingling Baicao Sutra, although it was looked down upon by Hao Yan, even Hao Yan himself had to admit that the ancestor of Lu Mengyue, as a world-level Yuan pharmacist from a large domain, could already be regarded as a talented person in a domain.

The Qingling Baicao Sutra created by the ancestors of the Lu family, as a method of refining medicine, but it has found another way, not relying on the yuan fire to quench the essence of medicine, and even does not need a medicine furnace to condense the medicinal power, the essence of this set of medicine refining methods lies in growth!

Moisturize all the raw spirit grass through a unique technique to stimulate its growth potential, so that the spirit grass can be fused by itself to form a medicinal seed, cultivated in the fertile soil, and directly grow the last desired yuan medicine!

Although this method of growth will take more time than the ordinary method of refining in the medicine furnace, the average quality of the yuan medicine that grows on its own will generally be very high, far exceeding the level of the refining of the medicine furnace.

However, without the flame quenching process, it is much more difficult to combine various raw materials, and the more raw materials required, the more difficult it becomes.

And at this time, in front of Hao Yan, there were dozens of kinds of spirit grass spirit fruits!

"Click-"

Hao Yan squeezed his fist:

"So—let's get started!"

As soon as he finished speaking, he saw a turquoise blue fruit, which floated with his vitality, and the detached vitality under the precise control was like a delicate finger, skillfully peeling and removing the seeds of the fruit.

And Hao Yan's own hands were not idle! While the Yuan Qi was distracting from the body, he also picked up several blades of grass with his own hands and squeezed out the juice in them to reconcile!

The demons on the periphery were amazed, but they didn't know that Hao Yan had already broken out in cold sweat on his forehead at this time.

After all, he is just a remnant soul, Xia Li has not yet reached the Gathering Spirit Realm, and at the moment when he can't refine the soul consciousness of the two of them, it is actually very draining for Haoyan's mind to divide his mind like this.

But there is no way, the dozens of spirit grass spirit fruits in front of him must be processed as soon as possible, otherwise when the last material is processed, the medicinal power of the first material may have already escaped.

"Master—"

Xia Li's weak voice sounded from the sea of knowledge: "What are you playing again?"

"Play?!" Although Haoyan's mind needed to be highly concentrated at this time, he made an indignant joking gesture:

"I'm refining a big medicine for you! But you think you're playing with your teacher?

Xia Li rolled his eyes, of course he knew that his master was making fun of him again, and seeing that Haoyan needed to concentrate now, Xia Li didn't continue to bother him, but just hid in the sea of knowledge and observed quietly.

"What are you looking at?

Who knew that Hao Yan directly closed his eyes forcefully, blocking the sight of the two, but he was still blindly manipulating his hands, which made the surrounding demons so shocked that they couldn't close their mouths.

"Master——!" Xia Li just wanted to protest, but he was reprimanded by Hao Yan again:

"You can just take care of your own cultivation now! Whether it is refining weapons, formations, or refining medicines, they are all sideways! Only cultivation is the road to truth!"
