The original intention of alchemy was to use the cooperation between various materials to achieve the purpose of healing or increasing combat effectiveness, various materials have different characteristics, and if these materials cooperate with each other, it is possible to better express their own characteristics, and the purpose of alchemy is this. Although the formula of the alchemy potion is very complicated, it is also a rule to follow, for example, the two strains are both healing elixirs, if they are fused and refined into alchemy elixirs, it is possible to make a more powerful healing potion, or it is possible that the healing effect is weakened due to the mutual influence of the medicinal properties of the two elixirs, and the probability of refining a potion that is harmful to the body or even highly toxic is very small. And if the two materials that are themselves highly poisonous are how to become alchemy potions, then the possibility of refining poisons is naturally greater, but it is also not ruled out that it is possible to refine some potions that are beneficial to humans. It is precisely because many materials have not only characteristics that various potions have to be tested before their final effect can be determined, and many alchemists discover a variety of alchemy formulas every year, but most of these formulas have no practical significance, such as the potions have great side effects, or the value of the potions themselves is not as precious as the materials used themselves, or there are already more simple and practical alchemy formulas, The Alchemy Guild provides a platform for many alchemists, once an alchemist discovers a valuable alchemy formula, he can hand over the formula to the Alchemy Guild for testing, and the Alchemy Guild will test the specific role of the alchemy potion and whether there are similar alchemy formulas in the guild, if the alchemy formula is deemed valuable by the Alchemy Guild, then the guild will give the alchemist a considerable reward, and the alchemy formula will also be collected in the Alchemy Guild. And the discoverer of this recipe will also be recorded in the book with the recipe.

It is precisely because of the practice of the Alchemy Guild that the Guild has a steady stream of fresh blood, and alchemy has slowly integrated into everyone's daily life, and the Guild has become more powerful.

In the long history of alchemy, a variety of alchemy formulas have emerged, and some alchemists accidentally found that some of the potions born by accident due to alchemy failure actually have very strong toxicity, and slowly some alchemists took the sword sideways, and began to refine some highly toxic potions for use in battle, at the beginning, such alchemy elixirs were not recognized by mainstream alchemists, It wasn't until later that an alchemy master killed a cultivator of the Venerable Realm with a highly toxic alchemy potion in a head-on battle, that this view slowly changed, and later the Alchemy Guild also added the highly toxic alchemy potion to the alchemy assessment, whether it is a potion that can refine and heal injuries and increase combat effectiveness, or a potion that can cause damage to the enemy with poison, it can meet the requirements of alchemy promotion. And the reason why Yaolin researched this potion was also Dongfang Xiao's instruction, after all, the strength test within the scope of the whole hospital was about to start again, if Yaolin could master some potions that could be used in battle, then he would also be able to get a better evaluation in this competition.

And the elixir that Fang Cai was an alchemy potion discovered by Yao Lin inadvertently, and in terms of effect, the elixir should also have some value.

Of course, this was just a few episodes on the road, and after wasting a few days in the forest, everyone finally arrived at Yunluo City, rode the spatial teleportation magic array to Yinling City, and then entered the academy. Unlike last time, this time everyone came to the academy a lot earlier, and there were almost ten days before the official start of the wish, and the reason why they came to the academy in advance was because there were some things to discuss with the demon family, after the strength test within the whole academy began, some elixirs that can improve combat effectiveness, as well as all kinds of weapons and equipment will be very popular, so Dongfang Yu also wants to take advantage of the ten days to prepare well, and when the time comes, he will make a fortune. And Dongfang Xiao continued to be his shopkeeper, because this time he didn't have to participate in the test, so he was probably the most leisurely one among everyone.

The entire academy seemed a little deserted, but because some students were too far away from home or other reasons, a small number of students chose to stay in the academy, and Dongfang Xiao also took this opportunity to go to the puppeteer guild to visit, wanting to visit No. 1 and Elder Red Eyebrows to see what kind of point the puppet's body production had reached.

"What, neither the President nor Elder Redbrow are here?" After arriving at the guild, Dongfang Xiao learned the news and was very surprised.

"Vice President, the President and the Elders left a message before leaving, if the Vice President comes to the Guild, let me tell you that they have gone out to look for rare materials, and they will be back in about a month, and all the affairs of the Guild will be handled by you for the time being."

"Is it another month?" Dongfang Xiao frowned, the person in front of him was also a high-level member of the guild, and many affairs in the guild were handled by him, although it was said that Dongfang Xiao's status was higher than him, but because of his personality, Dongfang Xiao almost never exercised his rights as vice president.

"Now that the vice president has arrived, the affairs of the guild are ......."

"I'll leave it to you to deal with it, you know, I'm the worst at dealing with this stuff." Dongfang Xiao patted him on the shoulder with a smile, and then turned to leave, leaving only the guild senior who wanted to say nothing nodded helplessly. He can't be regarded as an old man, although the puppet making technology is not strong, but the contribution to the guild is undoubted, in the entire guild except for those elders who don't care about things, as well as the president and vice president, his real power is basically the greatest, although he is a little helpless for Dongfang Xiao's behavior of throwing off the shopkeeper, but he is not disgusted, he knows very well in his heart that if he can get the favor of this vice president, then his chances of being promoted to vice president in the future will be greater.
