When Zang Feng heard this, he couldn't believe it, but when he put his nose close to the roots, he really felt the air, which was even more refreshing, and he couldn't help but sigh: "Ah! This is so amazing, this immortal herb, crystal green, seems to be a kind of green plant, what is its name?"

Frost said: "If you go down again, you'll know!"

So, Zang Feng was excited, and rushed down the steps again. For a while, he saw that on the rock wall, there were still dense glowing roots, but he didn't find anything special. But as he continued to walk down, suddenly, Zang Feng found that the green light was particularly dazzling on the rock wall. Zang Feng hurriedly approached. It turned out that among those fibrous roots, there was a glowing ginseng the size of an arm. And, if you look closely, this green light ginseng is not only full of rhizomes, but also bulging and bulging, with the surrounding body, it is also bright and dark, as if it is really a villain, in this underground secret channel, breathing!

When Zang Feng saw this, he was greatly amazed, and couldn't help but exclaim: "Ah! There is such a big ginseng......! It's still breathing!"

At this time, Bingshuang also followed, and said with a smile: "Yes! This plant is a specialty of our Medicine Immortal Valley, fluorescent ginseng! And ginseng is generally a shade-loving plant, with dwarf branches and leaves on the ground and developed rhizomes underground. Not only is this special fluorescent ginseng sent, but the roots must also go deep into the ground to produce such a huge root mass, otherwise it will not be able to bear at all. The reason why those fluorescent fibrous roots are desperately looking for stone crevices and burrowing deep into the earth is to find a suitable space to produce this kind of ginseng!"

Zang Feng listened and said: "No wonder, when I didn't go down the stone steps just now, when I went down to the depths, on both sides of the stone wall, there were all capillary roots, it turned out that the depth was not enough just now!"

Bing Shuang said: "Yes! This kind of ginseng can not only emit light and produce oxygen, but it can only grow in the specific environment of the Medicine Immortal Valley that I have sent! And after Ling Xu's master, according to the records in the Medicine Immortal Sutra, cultivation and improvement, only at a certain depth in the ground, can the roots grow strongly! Therefore, if you are brought ashore, you will not be able to see this glowing ginseng at all!"

Zang Feng said: "Ah! In this way, our Medicine Immortal Valley is really a blessed land of feng shui! Moreover, the Medicine Immortal Sutra I sent is also magical, this time, we must not let that flying knife man take it away!"

Frost said, "Yes, so, let's continue to walk down the stone steps!

However, at this time, Zang Feng may have been attracted by this 'fluorescent ginseng' that he had never seen before, and at this time, he was staring at the huge ginseng, unwilling to leave, and said: "Let me see it for a while! Just a while!" So, Zang Feng stared at the beautiful jade-like, crystal green glowing ginseng in front of him, and saw that it was still drumming, releasing fresh air, smelling it in his nose, he was dizzy, and he was almost drunk!

Zang Feng stared at this huge ginseng, dizzy for a while, and suddenly remembered that when he was in the prison of the robber department, he had seen a small glowing firefly lying next to the air hole of the stone wall, and with every breath it breathed, its body was bright, and it was also bright and dark. This glowing ginseng is like this! So, he hurriedly said: "This ginseng breathes, one bright and one dark, it looks very much like a small glowing firefly crawling on the rock wall! It's just very big!"

Frost listened to this and said with a smile: "Haha! You can associate it! But the grass, trees, fish and insects have the same thing! It's just that when the little glowing firefly is exhaled into oxygen, the body's energy burns more violently, so the body is also brighter. However, the fluorescent ginseng in our Medicine Immortal Valley, what we inhaled was the turbid breath of the earth, and what we exhaled was oxygen. And when it exhales oxygen, the rhizome shrinks, and the light shines brighter!"

When Zang Feng heard this, he suddenly realized: "I see, I can still absorb the turbid qi! Then, if this ginseng is eaten, it will not only absorb all the turbid qi in the body, but also release sufficient oxygen and light in the body! This will definitely be of great benefit to the body!"

Frost heard his voice and smiled, "Even so, you're not a dead person now, what yin qi does you have in your body?"

When Zang Feng heard this, he was even more amazed: "Ah! Frost girl said this, it seems that this glowing ginseng is not only beneficial to the body, but also can be brought back to life? Zang Feng was underwater before, when he was pulled by dolphins, if he really didn't hold his breath and choked to death by the water, Frost girl, feed me a fluorescent ginseng like this, and I can come back to life!"

If you drown in the water, I won't let you enter this secret passage, where do you have ginseng to eat? If you drown, I won't save you!"

Zang Feng said: "Then I am not drowned now!" After that, Zang Feng's stomach growled twice!

At this time, Bingshuang also knew that because the two of them were sitting on the snowy divine bird and listening to the long narration of the 'Guardian Beast', they had not eaten or drunk for three days and three nights. Besides, Zang Feng is at the bottom of the water, under the water, holding his breath, and the turtle breathes to stay on his face, at this time, it is indeed time to replenish his body! So, Bingshuang said: "Okay! Since you have successfully passed the level underwater, let's continue to walk down, and I will pick a big one for you in a while!

When Zang Feng heard this, he was overjoyed and said, "Disciple, thank you Frost Girl! But when the disciple sees this ginseng, he is already in good condition!

Bingshuang said: "This is not allowed to move! The ginseng in front of you will be used as a headlight here! If you pick it off and eat it, the top of this dark passage will look dim! Moreover, the reason why it grows so well! It is also because of the medicine fairy valley, and it is snowing. This ginseng variety likes yin and cold, and it has only grown exceptionally strong this year! Since the top is not vinegar, the bottom must be even stronger!"

Zang Feng couldn't help but rejoice: "Yes! This ginseng is even better than the thousand-year-old ginseng I have seen! It is said that the better the quality, the better it is, the more difficult it is to find and excavate! Therefore, it is also deeper underground!"
