Of course, Chen Hao didn't know what the alchemists outside thought of him, and all his attention was now focused on refining the potions in his hands.

That's right, it's an intermediate-grade red medicine.

He is now starting to refine the mid-grade red medicine on a large scale, of course, this is not to practice his hands to warm up and find a feeling, but for other purposes.

Chen Hao took out a large amount of materials from his pocket like this, and continued to refine the intermediate red medicine, anyway, the materials here can be used casually, and there is no need to worry about waste.

Two hours later, Chen Hao had already refined a huge number of intermediate-grade red pills, and the success prompts that kept sounding also attracted the attention of many alchemists in the audience, but when they knew that he was just refining simple intermediate-grade red pills, almost everyone cast disdainful glances at him, thinking that he was now eye-catching, so he was making a fool of himself.

Even the president of Qingfeng City didn't know what Chen Hao was thinking, how could he start refining the intermediate red medicine, and he practiced a lot.

After completing a large number of intermediate red medicine refining, Chen Hao stopped, he opened the experience he had recorded during the previous alchemy, and flipped through the pages one by one.

After attracting a wave of eyeballs before, everyone knew that he was not doing his job, nor was he paying attention to Chen Hao's side.

On the contrary, it was Cangyue Wushuang's side that attracted a lot of people's attention, and now almost everyone's eyes are focused on her.

"What is she refining?" An alchemist who had just returned to the audience asked the people around him.

"I don't know, but just now she used [Dragon Kiss Grass], which is a very rare high-grade material, and it seems that it should be a great potion to be refined."

"She has failed several times, refining the potion several times without success, and she has used several extremely rare techniques, she should be refining a very rare potion."

"Really? Then I'll see. The words of others also aroused the curiosity of this alchemist

........

Red Rose was still trying all sorts of methods, and with her own experience, she began to combine several potions organically, but they basically failed, and there was no hope of success at all, but this was the only way she could think of it.

The refining work on the field was going on anxiously, and almost everyone began to do it, even the alchemists who couldn't think of a way to do it, after all, time was limited, and it was better to get something than to waste time there.

Except for Chen Hao, who was still looking through his diary there, everyone else started to move.

Qingfeng City President looked at Chen Hao, not knowing what he was thinking now.

Eight hours passed, Chen Hao looked at his notepad, closed his eyes and pondered for a moment, and finally started to work.

He began to take the ingredients out of his pocket and refine the potion.

It's a pity that he failed the first time he refined.

Seeing that the failed potion was left in the magic cauldron, Chen Hao made an unexpected move, he poured the liquid in the magic cauldron into his mouth.

He only felt a chill on his body, shivering with cold, and then began to heat up again, so hot that he wanted to take off his clothes, and the amount of blood on his body began to drop rapidly.

Chen Hao hurriedly poured the intermediate red medicine into his mouth, and at the last moment, he stopped the declining blood volume, and after a while, the cold and hot feeling disappeared.

After his body returned to normal, he muttered something while quickly jotting it down on his notepad.

"Well, the material ratio should be adjusted again, and the heating time of the magic crucible should be shortened."

After recording this information, he began to refine the next material, this time adding a different material.

The second time was still a failure, and after the failure, the liquid in the magic cauldron was green and bubbling.

Chen Hao looked at the green bubble and muttered, this thing shouldn't hang up immediately if he drank it.......

However, in order to develop a new alchemy formula, he had to drink it anyway, just in case he still put the intermediate red medicine in front of him, and if something happened, he would drink the medicine immediately.

This is the method that Chen Hao thought of, to test the medicine by himself, and to test the new drug through human experiments, because the reaction of the human body is the most intuitive reaction.

Through different combinations, and then according to the human body's feelings, the information is recorded, and then the optimal answer is found.

He pinched his nose and poured the liquid from the magic cauldron into his stomach.

After a moment, he only felt a sharp pain, and the pain was so painful that he lay on the ground, clutching a few bottles of intermediate red medicine in his hands.

Chen Hao endured the pain, drank the intermediate red medicine, and first kept the blood value that kept falling, but the pain continued, he lay on the ground like a prawn, and rested for a while before he got better.

After he got up, the first thing he did was to record the information just now, the ratio of the medicine, the heat, and the effect of taking it.

After the second test was recorded, he began to refine the third potion.

These three refining methods were all random combinations of the materials on the potion recipes he had already mastered, and obtained different medicinal liquids through different combinations and different blends.

Of course, the result of such a combination was a failure, but he still drank the potion and experimented with his own body.

Soon, Chen Hao's movements attracted the attention of everyone in the audience, and everyone saw that the young man at the No. 44 experimental table poured it into his mouth no matter what was in it after refining the potion.

After drinking, he either saw his head smoking, or he had green spots all over his body, and his head was once again swollen like a pig's head.

But even so, he still didn't stop refining in his hands, as long as his body could still stand up, then he would drink the medicine in his hand.

"This young man is also too hardworking, and he actually uses his body to test the medicine."

"It seems to be from the Alchemist Guild of Qingfeng City, no wonder he prepared so many mid-level red pills before, it turned out to be for this."

"I really can't imagine when there were crazy people in Qingfeng City?"

"Interesting, really interesting, this young man.... Interesting. An old man in a purple and gold robe touched his beard and watched Chen Hao test the medicine on it.

Another 4 hours passed in the game, Chen Hao tried countless combinations of materials, none of them succeeded, they were all failures, his body was also tossed by those strange medicines I don't know how many times, a few times he almost hung up, fortunately he took the medicine in time.

He tried his best to test the medicine, and the conclusions and information he came to became more and more abundant, and his notepad recorded hundreds of pages of drug testing experience, nearly 500 kinds of material ratios, of course, these information are all failed information, and it is useless in the eyes of others, but Chen Hao has recorded them one by one.

He knows that if he wants to make a real breakthrough, then he can only find the right answer in these failed cases.
