Xi Rong is an eight-star alchemist, naturally he has seen countless elixirs, his ability to recognize medicine is undoubted, and these materials are also taken out by him, he naturally knows it in his heart.

He had long known which ones were elixirs, which were useless materials, and which were poisonous.

In particular, Li Chen took the wrong twelve kinds of materials, ten of which he obtained in a ruin, and this material is still preserved in zài special vessels, although I don't know how many years have passed, but it is not weathered, it is very magical.

It's a pity that he confirmed and verified again and again, and finally found that these materials were either useless or highly toxic, and they were all waste products at all, but after all, this was the harvest of his own adventure, but he was reluctant to discard it, so he kept it in the corner of the storage ring.

So he was very impressed by these ten materials, as soon as he saw Li Chen take them out, he knew that Li Chen was going to be deducted a lot of points, and the other two materials were also poisons, and they looked very similar to the two elixirs, and he could also confirm it.

It can be said that Xi Rong is very confident in his judgment and will not make mistakes at all. It is normal for Li Chen to be unhappy with Li Chen's questioning of himself, especially his identity and status, which is tantamount to being questioned about his authority.

After he took out these twelve materials, he displayed them one by one and said in a loud voice: "Among your twelve materials, the names of these seven materials are Larch, Bayan Flower, Deer Black Charcoal, Shatian Jade, Red Yang Bone, Rock Root, and Bamboo Shadow Ice, all of which are useless materials, do not contain a trace of aura and medicinal power, and cannot be used to refine any elixir at all. ”

"And the other five materials, their names are gray hairy red grass, shadow black vine, deep sea rootless lotus, toad skin atractylodes, Yin Chen ginseng, all contain toxins, accidentally refined into pills, not only not beneficial to people, but even harmful. In particular, the gray hairy red grass and the shadow black vine are highly poisonous, and those who are less powerful may be in danger of dying if they eat them. ”

"If you take a closer look, the appearance of this gray-haired red grass is very similar to the elixir black-haired red grass, the difference is that the fluff color on the stems and leaves is different, one is gray hair, the other is black hair, and the subtle difference in medicinal effect is the same world! The black-haired red grass is an elixir, but the gray-haired red grass contains highly poisonous! You just regard this gray-haired red grass as a black-haired red grass. ”

"∫↘dǐng∫↘diǎn∫↘小∫↘ says,.》.o≦s_(); As for the shadow black vine, it is the same thing, the one that can be used to refine the elixir is the shadow red vine, the skin color of these two vines is different, you will use the shadow black vine as the shadow red vine. ”

Xi Rong spoke eloquently like this, and explained the names and differences of these materials very clearly, showing his solid foundation and convincing.

After speaking, he looked at Li Chen and said: "Now I tell you all the names of these materials, if you don't believe it, you can go back and check the relevant classics, and you will know if I am right." ”

In fact, when Xi Rong said the names of these materials, someone was already looking for relevant classics.

"I found an introduction to the deciduous stone, the red sun bone and the bamboo shadow ice, this larch refers to the stone dug under a tree called the luscious tree, the red yang bone is a kind of skull called the red yang beast, and the bamboo shadow ice is the ice formed by the dew on the leaves of the bamboo tree that grows in the ice field, but there is only one name and their origin description here, but there is no description of the purpose. ”

"Because it's useless, naturally there is no introduction of use, didn't Elder Xi say it, these materials don't contain a diǎn aura and medicinal power, how can they be used to refine pills?"

"Elder Xi is an eight-star alchemist, his words should not be wrong, Li Chen is just unwilling to lose to Xu Feiyu. ”

The guards in the audience were discussing at this time, and then looked at Li Chen with interest, wanting to see how the other party would react after being exposed.

"What?" Li Chen was stunned at this time, he listened to Xi Rong's words, and then looked at the twelve elixirs picked out by the other party, his face couldn't help but twitch, these materials are useless?

"You said it's useless and poisonous, then give it all to me. He blurted out.

Putting aside the gray hairy red grass and the shadow black vine, the rest of the ten materials that Xi Rong called useless and poisonous were the main materials for refining the Qianyun Pill!

For example, the deciduous stone, which needs to be precipitated and absorbed for at least hundreds of years under a spirit tree called the luscious tree before it can be born, and the red yang bone, the red yang beast has been almost extinct in ancient times, and it is too difficult to find one.

The other materials are also very hard to find!

But these materials for refining the Qianyun Pill were rarely collected together, and they were actually regarded as useless by Xi Rong!

Is this really the level of an eight-star alchemist? He couldn't help but be a little skeptical.

"Now you have nothing to say?" Seeing Li Chen's stunned appearance, Xu Feiyu said jokingly at this time: "If you want to get by, don't you want to see who Elder Xi is? That's an eight-star alchemist, a half-step Dan King! Where is it so easy to be fooled by you, Elder Xi can recognize these materials." ”

In his opinion, Li Chen's final objection was just a futile struggle, and it would not change the result at all.

The winner is still his, in the end.

"Li Chen, now that you have picked out all the wrong materials, do you still have any questions?" Xi Rong had always maintained his demeanor as an elder, although he was slightly unhappy with Li Chen's challenge to his authority, he still asked patiently.

"Back to Elder Xi, Li Chen still has a different opinion on the twelve materials pointed out by Elder Xi. Li Chen thought about it and felt that he still had to insist on himself, so he bowed and said.

"What? Li Chen, what does he mean by this? Is he going to continue to mess around?"

"Li Chen, you should quickly admit defeat, you are still a man like that, what's the point of messing around?"

"Yes, Elder Xi is so easy to fool, Li Chen, you better admit defeat quickly, there are still two competitions ahead, and you may not lose to Xu Feiyu. ”

Hearing that Li Chen was still reluctant to admit defeat, the audience couldn't help but quarrel again.

In fact, from the beginning when Li Chen refused Xi Rong's apprenticeship, everyone felt that Li Chen was a little arrogant, and many people's perception of him had decreased. Now seeing that the latter is still questioning Xi Rong, an eight-star alchemist, they all feel that Li Chen is beyond his strength, and even a little ignorant of what to say.

"Li Chen, what do you mean?" is that Xi Rong couldn't help frowning at this time, he was already patient enough, after all, he was an eight-star alchemist, and he was at the forefront of the Dan Dao in the entire South Wind Country, but the other party repeatedly questioned his authority, and his patience was also limited.

"If I'm not mistaken, most of these materials shouldn't have been specially collected by you, Elder Xi. There are ten of them, and someone should have collected them all before they were obtained by you, Elder Xi. Li Chen was not polite at this time, and said directly: "Elder Xi, haven't you thought about it, if these materials are useless, how can someone deliberately collect them? And some of them are also recorded in the Danshu Pharmacopoeia?"

"What do you mean?" Xi Rong's body shook violently at this time, and he looked up at Li Chen in disbelief.

Seeing Xi Rong's reaction, Li Chen knew that he had guessed correctly, so he continued: "As far as I know, among the twelve materials that Elder Xi picked out, ten of them were the main materials for refining the Qianyun Pill, so they were specially collected. ”
