Looking at the two pictures in Yang Laoshi's hand, the old man shook his head and said, "I've never seen it, what kind of medicinal herb is this?" ”

"This is the medicinal herb I need, since the uncle has not seen it, then I will go and ask elsewhere." Yang honestly said.

didn't get the result he wanted from the old man, although it was expected by Yang Honest, but he couldn't help but be a little disappointed in his heart.

Leaving the old man's stall, Yang Laoshi held Wangcai and searched for them one by one, until the last stall was finished, not only did he not find the three medicinal materials for refining the six-grade strengthening potion, but he also did not find the many medicinal materials needed to refine other potions.

As the old man of the first stall said, at this point, there are not many medicinal materials to choose from, and the better ones, or the relatively rare ones, have been bought early.

In desperation, Yang Laoshi had no choice but to return to his residence with Wangcai, preparing to get up early tomorrow and go to the old street to try his luck.

Back at home, Yang Laoshi casually made some food, put lunch and dinner together, and saved a meal. Afterwards, Yang Laoshi came to a separate room.

This room was changed by Yang Laoshi into a room for temporary refining of potions, not so much as changing, but directly saying that he put all kinds of utensils for refining potions in the Sumeru space in this room.

The potions that should be refined have all been refined, and he entered the refining pharmacy at this time for the snake hyacinth poisonous herb obtained in the Sumeru space.

With a wave of his big hand, a red demonic aura erupted from his body, enveloping the entire room. Immediately afterwards, Yang Laoshi casually swiped the space beside him, the space was opened, and a snake hyacinth poisonous weed appeared in his hand.

Then, I saw Yang Laoshi grab the arm of the snake hyacinth poisonous weed, and a rich blood-colored demonic aura emerged again.

The demonic qi appeared, and immediately wrapped the snake hyacinth poisonous weed, and the next moment, the snake hyacinth poisonous weed disappeared and turned into a green water droplet the size of a little thumb.

This green droplet is the liquid inside the snake hyacinth poisonous weed!

In the past few days of refining medicine, Yang Laoshi found that his demonic qi was used in refining potions, not only was it not as troublesome as before, but at the same time, the speed was also much faster, and he could dispose of a medicinal herb in a casual manner. Get it in the form you want, in liquid or powder form.

It was precisely because of this that he was able to refine all the supporting medicinal materials in the Sumeru space into potions in just four days.

The discovery of this made him feel that he had used to refine the potion, and maybe he also used demonic energy.

With a few fingers, the green liquid suspended in the air entered a test tube, and Yang honestly studied it carefully.

Before he started, he chose to use his demonic energy to envelop the entire room, because he was worried that when extracting the juice of the snake hyaccia poisonous weed, the poison would overflow and hurt the people nearby. After all, the toxicity of the snake hyacinth poisonous weed is really terrifying, not to mention the poisonous gas that escapes from the juice, even if the juice is not extracted, the poisonous gas that escapes from the snake hyaccia poisonous weed itself is scary enough.

For the sake of safety, Yang honestly and decisively sealed his room completely.

Looking at the juice in the test tube, Yang Laoshi's face showed contemplation, what he has to do now is to fully extract the toxins in this juice, and then think about whether he can properly add some other medicinal materials to enhance the toxicity, and refine a strong toxic medicine that he has never refined, even in his memory!

The use of poison, although the means are not very glorious, but Yang Laoshi does not have any guilt at all. The two sides fight and fight, looking at the real ability, as long as they can kill the other party, that is their true ability, regardless of whether he uses poison or medicine.

As long as you can take down the other party, although the means are a little despicable, you can't deny the final result it brings!

In one night, Yang Laoshi took out the snake hyacinth poisonous weed from the Sumeru space many times, and then extracted the highly poisonous juice inside it for research, and unconsciously, there were already several test tubes in front of Yang Laoshi's body, and there was the juice of the snake hyacinth poisonous weed.

Some have been dried up, some are still in the form of liquids, and some have been added to other liquids to become another highly toxic existence.

There are many test tubes, but none of them contain finished products. Except for a small number of semi-finished products, everything else is scrapped and has no research value.

Before the test tube, Yang honestly sat down with a tired look, and concentrated on tinkering for a whole night, how could there be no reason not to be tired. Creating a new type of potion is far from being comparable to refining the potion that you were once extremely proficient in, and the former consumes more refining energy than the latter.

Because, in addition to the energy-consuming refining and blending, it is also necessary to rack your brains for various analyses and practices, which is the most brain-hurting thing.

"Fortunately, the number of snake hyacinth poisonous weeds is enough, if the quantity is too small, I am afraid that the real medicine has not been developed, and the main materials have been consumed."

Sitting on the chair, Yang Laoshi took a sip of medicinal tea to refresh himself, and then sighed to himself. Only those who have experienced it firsthand know how difficult it is to develop new types of medicines.

Turning his head and looking out the window, he found that the sky was already slightly white, Yang Laoshi put down the medicinal tea in his hand and stood up.

"At this point, there should be someone in the old street who has set up a stall, I don't know if I can find the medicinal materials I want when I go at this time."

As he spoke, Yang Laoshi walked towards the door, his body passed through the blood-colored demonic qi, and he came to the living room with ripples.

Demon Qi Barrier, he has no idea of withdrawing for the time being, at this time, the room can be said to be filled with poison, once Yang Laoshi removes the Demon Qi Barrier, then the rich poisonous gas in the room will definitely spread to the outside world, and when the time comes, I don't know how many people will die under this poison.

This is something that Yang Laoshi doesn't want to see. He didn't want to let innocent people die because of his own mistakes.

"Wangcai, I'll go out, you take care of your home, don't let anyone get close to this room." Yang honestly admonished.

"Wow!" Wangcai called twice in response, then nodded.

When Yang Laoshi appeared in the hall through the demonic qi barrier, Wangcai had already sensed Yang Laoshi's arrival, and at that time, it had already woken up.

Leaving Wangcai to guard the house, Yang Laoshi took the door and walked straight to the location of the old street.

Outside, the vendors were already getting busy, all kinds of shouting, bargaining, the sound of butchers deboning and chopping meat, all kinds of sounds sounded, it seemed a little noisy.

Yang Laoshi saw all this in his eyes, and couldn't help but feel a little in his heart, this is life, this is the life of ordinary people, tired and busy all day long in order to survive, day after day, year after year, and he can't grasp the time that flows from his fingers.

Sighing and shaking his head, he withdrew his gaze and quickened his pace towards Lao Cai.

It's already so lively outside, presumably the old street should be about the same place.

Thinking so in his heart, Yang Laoshi, who didn't want to return empty-handed, had no choice but to speed up the pace of progress.

Sure enough, when he came to Lao Cai, the sound of Lao Cai was even more noisy, it was completely like a vegetable market, the people who set up stalls, the customers who came to buy things, were about to break the whole old street!

The corners of Yang Laoshi's mouth twitched, he thought that although he came not too early, it was not too late, but after coming here, he realized that he was wrong, he was still late!

Because, many people have already bought their ideal medicinal materials and left the old street with a smile on their faces!

"I'll go! I didn't sleep all night, sir! I still didn't rush to the front! No, this time you can't go home empty-handed anyway! ”

Thinking so in his heart, Yang Laoshi entered the first stall in the old street!

The person who set up the stall in the first stall is really no longer the old man of yesterday!
