Within an hour, Dou Min identified seven immortals for Lin Feng. But there was a kind of pill that he didn't even know.

"The old man has been practicing alchemy for more than three thousand years, and I never thought that there is a pill that the old man has never heard of!" Dou Min was quite moved.

"Little friend, can I ask the old man to scrape a bit to verify?"

Dou Min looked at Lin Feng and asked.

"Aren't the older generations afraid of being poisonous?" Lin Feng asked in surprise.

Although the six elixirs identified earlier are all elixirs for physical fitness and are beneficial to practitioners, no one is sure whether this is the case right now.

Although theoretically speaking, normal people would not store poison pills in the basement, but everything is in case, right?

Hearing Lin Feng's words, Dou Min smiled and stroked his beard, but a proud expression flashed across his face: "I asked myself, although he is not as good as those of the sages, he is absolutely extraordinary. generation!"

"Little friends, don't worry!"

"I have my own way to protect myself, even if this is a poison pill, it won't hurt if I swallow it!"

Seeing Dou Min so confident, Lin Feng was skeptical, and finally nodded in agreement, saying: "Okay, since the old man wants to give it a try, let's give it a try!"

Dou Min immediately took a very slender knife, and carefully scraped a small amount of pill powder along the blue pill with dark lines on the surface.

Then he put it in his mouth and tasted it carefully.

Lin Feng sat in the position, staring at Dou Min closely, and assumed a posture that he would be ready to shout at any time if something was wrong.

After a few breaths, he saw Dou Min's old face flushed, and white mist appeared on the top of his head.

His whole body became like a stove, making people feel extraordinarily hot, and even the air was hot and a little distorted.

At the same time, there was a strange sweet smell exuding from this Dou Min.

"This pill, I'm afraid it's a holy pill, right?!" Lin Feng saw this, a look of wonder flashed in his eyes.

He doesn't know how to make a pill, but seeing Dou Min's reaction, he also knows that this pill is absolutely extraordinary!

About to go to the tea cup, Dou Min opened his eyes, exhaled a long suffocating breath, and exclaimed: "This pill is amazing!"

"How is the old man? Is there any way of tasting?" Lin Feng asked curiously.

Dou Min smiled and said: "Don't worry, little friend, although I still don't know the name of this pill, it is still a pill for blood circulation, but it is even higher than the golden marrow pill!"

After a pause, he sternly said: "This dragon and tiger pill is extremely overbearing. If the cultivation level is not in the final stage of the perfection, and the body is not strong enough, it must not be used, otherwise it will not only be useless, but harmful!"

Lin Feng nodded slightly: "Understood!"

Immediately afterwards, Dou Min helped Lin Feng identify several elixirs, only one was to increase the strength of the soul, and the rest were either healing elixirs or elixirs for increasing physical strength.

Lin Feng couldn't help sighing, this Saint Yuan Realm really deserves to be a physical realm!

"Does the little friend still have?" Dou Min smiled and stroked his beard.

Today, he helped Lin Feng identify more than a dozen kinds of elixirs, and his gains were not small. Some of these medicines are almost lost, and some of them are extremely rare.

For a person like him, being able to observe these medicinal pills up close is already a huge gain.

"Old predecessors, look at this gourd medicine!" At this moment, seeing Lin Feng smiled slightly, a purple gold gourd appeared out of thin air in his hand.

It is not made of jade, but a purple-gold gourd, which is like a magic weapon in the hands of the old gentleman in myths and legends.

Lin Feng also only had three such purple gold gourds.

In fact, he got six from the basement earlier, but Ji Yuxuan also left three.

"This is..." A ray of shock flashed in Dou Min's eyes.

He could clearly perceive that this purple golden gourd was not a vulgar thing, at least it was a Taoist implement of the near-sage level.

Even the utensils that carry the pill are like this, it is hard to imagine what the pill is in it!
