And this structure of the two stone gates is obviously to prevent the flow of well water from pouring in!

At this time, Frost saw the surprised Zang Feng and asked her where this was. Frost didn't answer, just walked up the steps and said, "You come up quickly!"

Zang Feng had no choice but to drip waist-high well water and hurriedly walked up the steps! At this time, Bingshuang stood on the steps and pressed on the cliff wall again. I only heard the "click, click", and there was another sound in the crack of the stone, and the second stone door that had been opened actually fell again! After the second stone door was also tightly closed, Frost said to Zang Feng: "Follow me!" Immediately, Frost went up the steps.

At this time, Zang Feng saw that Bingshuang didn't answer, so he had to follow her and also go up the steps. Because at this moment, he can finally breathe freely, and he can see that the green light above the steps is brighter, and the air is extremely fresh. Naturally, he thought that above the steps, there must be the ground. Otherwise, how could the air be so fresh? Therefore, even if Bingshuang didn't answer where it was at this time, Zang Feng thought: Go up the stairs and return to the ground, and naturally you will know.

So, after Zang Feng could breathe, his physical strength also recovered slightly, and at this time, he actually took the lead in running, taking three steps and doing two steps, but he overtook the front of the frost. Because, at this moment, he really wants to hurry up and walk on the ground!

However, as soon as he reached the top of the stone steps, he saw that there was no way out. I touched the shiny place above my head, but I felt that it was just a hard rock that reflected the light elsewhere, and for a while, I thought it was a green sky at night. And the stone steps, like an arched bridge, climbed to the top, and went down sharply. Zang Feng hurriedly looked down along the stone steps, only to see that the green light below was even brighter, but when he reached the downward stone steps, it seemed that he was bottomless, and he didn't know where it led! The green light that illuminated the rock above Zangfeng's head came from the depths of the downward stone steps.

At this moment, Zang Feng was stunned again, standing at the top of the stone steps, just dumbfounded, and said in a daze: "This ......"

And at this time, there were only more than 20 uphill steps, and Frost also walked up! Seeing that Zang Feng was stunned, he just urged: "You are so active, continue to walk quickly?"

Zang Feng said blankly: "This ...... Frost girl, where does this lead? Why are you still going downhill? I thought we were climbing to the ground after going up these uphill steps!"

Bingshuang said: "Where is this ashore? If we go ashore, I would have let the dolphins pull us ashore from the bottom of the Mirror Lake!

Hiding his head exclaimed, "Why haven't I heard of it before?"

'Frost' smiled: "If this time, you used the turtle breath rejuvenation technique under the water improperly and suffocated to death, I would not have brought you here! Fortunately, you were pulled by the dolphin, jumped up and down, and still survived, which shows that you have practiced the turtle breath rejuvenation technique I taught you to a certain level." Therefore, since you have joined the sect of my Medicine Immortal Sect, and you have been tested again this time, you can now be regarded as entering the house, and this secret can also be told to you!"

When Zang Feng heard this, he was surprised and said, "Ah! It turns out that the Frost Girl is going to bring her disciples to the secret room, so she has taken the underwater secret path." Otherwise, if the seven-colored shadow man secretly tracks him, he will be able to save and leak the entrance to this secret room!"

Frost said: "You understand!"

Zang Feng sighed again: "Ah! It turns out that the Frost Girl, at the bottom of the water, is dragging my ankle upside down, to test my kung fu! If Zang Feng had also learned the turtle breath rejuvenation technique taught by the Frost Girl to his disciples when he went deep into the desert ghost cave with Lu and the others, then Zang Feng would not have drowned at that time!"

Frost said: "At that time, it was because I didn't teach you this secret method again, although you were drowned, so I rescued you." If you drown again after practicing this turtle breath and rejuvenation surgery, I won't save it!"

Zang Feng said: "The disciple understands! Finally, the disciple did not drown for the second time this time! However, how can we send this secret room under the water, and those two stone doors must be for the way the water flows in, not to mention. But after entering the second stone gate, there are still uphill steps, Zang Feng was really bad for a while, and thought we were going ashore!"

Bingshuang said: "If there are no more than 20 uphill steps, despite these two or two stone doors, open them one after another, you can prevent the well water from not filling too much." However, after entering the stone gate, if it is going downhill all the way, the small amount of well water poured into it will not all go down the slope?

Zang Feng heard it and said, "Yes!"

Frost said, "Don't say it! Let's go down! We're short on time!"

Zang Feng said, "Okay!" So, he began, walking down the steps. However, the more he went down, the more he knew himself, and the more he went 'underground', but on the contrary, the more he felt the fresh air. Zang Feng couldn't help but ask: "Frost girl, why is the air so fresh underground? It is even fresher than the morning air on the ground! Before Zang Feng, he thought that we were going to go up to the land, it was not unreasonable!"

'Frost' smiled, "Well, go down again, and see what are the glowing ones in front of the secret passage?"

At this time, Zang Feng just quickened his pace and walked all the way down. He felt that the more he walked forward, not only the air became fresher, but also the green light in front of him became brighter and brighter!

Zang Feng couldn't hold back his footsteps, and ran down the stone steps. As soon as he came to the luminous place, Zang Feng saw that the rock walls on both sides were like spider webs, full of fibrous roots, and these fibrous roots were like those colorful lights, emitting green light, which was extraordinarily warm and bright! Zang Feng was surprised, and looked up again, and these spiderweb-like fibrous roots that climbed on the rock wall were actually thick roots drilled out of the cracks in the stone above his head, and the branches spread down. Zang Feng couldn't help but exclaim, "Frost girl, these glowing things?

Frost also followed, and said, "This is not the root of a tree, but the root of a fairy herb that grows in our herb garden on the shore of Mirror Lake! This kind of vegetation, although it is not big or conspicuous on the ground, has extremely deep roots. And because its roots can glow, in the ground, it is like a flashlight, and it can be found to drill through the cracks in the stone. What is even more amazing is that this kind of root can also exchange air with the branches and leaves on the ground, and the ability of the roots to produce oxygen is also extremely strong. Therefore, this is closed by a double stone door, and water cannot be poured into the secret passage, but the air is extremely fresh!"
