Secrets, caves, silence.

The enclosed space, the unfamiliar place, the quiet environment, and the long time made Tang Yan feel lifeless here.

The impression of this legendary treasure place in the secret realm to her was originally that it should be a prosperous and rich, countless treasures, and a place full of surprises in searching, but now, what she saw in her sight was nothing but barren and boring mountains and rocks, and there was no feeling of treasure treasure at all, in her opinion, this place was like a huge burial place!

Tang Yan shook his head, dispelling the superfluous thoughts in his mind, if there was really anything wrong with the secret realm, I am afraid that it would have been discovered a long time ago, and it would not be rumored that this place would be a treasure house. Maybe it's because of my bad luck that I was randomly thrown to this place, and if I want to find the treasure, I probably have to go to another cave.

This cave is so big, there is no exit after walking down for a few hours, Tang Yan sat on a big rock and rested enough, got up and continued to walk aimlessly.

The aura around her body fills her body, and between her breath and breath, the aura flows in her body, condenses, and grows, this is her cultivation method, which is simple and fast.

The silver bell in his arms was silent, and it had no other effect than to dispel the black fog before. The guiding effect that Yan Xing said was not found, and it was of little use in short.

The soil under his feet has changed from hard as iron to gradually softening, and after walking for a long time, he has also walked out of the range where bell plants grow, and Tang Yan can see these from the changes in soil quality.

took steps forward again and again, and after one step, the environment around Tang Yan changed instantly!

The original barren mountain cave environment is still there, but the difference is that on the ground here, between the cracks in the stones, there are dots of green, although it is only some moss, but it is not as barren and dead as before.

Did you just pass through another barrier?

From the gray and yellow color to the gradual green and sudden change, Tang Yan can only think of this reason.

She took a step back, and there were still a little green under her feet and on the stone walls of the cave, and after entering the barrier, if she wanted to get out, it was not possible to do it in one step.

"There seems to be no choice, and there is no way back." Tang Yan sighed, the road ahead was unknown, but she had to keep walking.

Starting from the little moss growing nearby, the more you go forward, the more eye-catching the green traces become, and the cave seems to have shrunk, and in the end, the width of her left and right sides is less than ten meters, and the top of her head, the height can reach 100 meters, the environment in front of her is a cave, it is better to say that it is a tunnel, the walls are crawling with green vines and plants, I don't know if there are small insects growing here.

In the unfamiliar environment, Tang Yan became more cautious, and observed the nearby plants by the way.

She understands pharmacology, and has a lot of research on various plants, and the vines that climb the wall are not the same as large vines, but after I don't know how many years of growth, the original small vines have grown to the thickness of an adult's arm, and the vines are covered with dead tree-like turf, and even the vines here have grown and can metabolize and molt on their own.

The faint sound of 'Sisi~' had already attracted Tang Yan's attention the moment it appeared, she stopped, identified the direction of the sound, and looked over there.

Five meters in front of her, on the vine-covered rock wall, a black-brown snake was coiled motionlessly between the vines, and if you didn't look closely, you would only see it as a tiny vine.

The small snake is not big, the fingers are thick, more than a meter long, and under the foil of the vines around it, it is motionless and inconspicuous, and it is not even easy to be found. The tongue is triangular and occasionally pokes out to sense the temperature in the air, and the dark purple spike can tell how venomous the snake is.

I'm afraid that ordinary people will die in the blink of an eye if they are bitten, even if a martial king is bitten, if he can't clean up the toxins in a short time, he will die soon.

Tang Yan is not afraid of poisons, and even says that she likes them, medicine is a family, not to mention that what she is best at is not the rescue of doctors, but the killing of poison!

In order not to startle the snake, Tang Yan tried her best to slow down and take out a few silver needles that were not rubbed, she was vigilant and observed, and she could do it at any time.

Although the small snake can be made with a silver needle rubbed with anesthetic, but while the anesthetic is effective, it may also destroy the effect of the snake's venom, so for the integrity and purity of the venom, she chose to use an ordinary silver needle to catch the little snake.

With a flick of her wrist, seven silver needles flew out of her hand and fell in seven different directions!

'Whoosh! Sou! Sou!! The moment a few small voices piercing the wind came to my ears, the silver needle had already fallen to its destination.

I saw that on the rock wall climbing the vines, a small snake with a very inconspicuous color was fixed on the body by seven silver needles, and the tip of the silver needle went straight to the rock wall, completely restricting the little snake's ability to move.

This hand flying needle was used by Tang Yan superbly, from the experience brought by the previous life and the hard training in this life, her hidden weapon throwing skills have been greatly improved.

Tang Yan withdrew his hand, walked to the side of the little snake that was fixed in a few steps, directly reached over and pinched the snake's head accurately, pulled out a silver needle on his head, took out a small porcelain bottle, and squeezed out the venom in the little snake's mouth drop by drop.

Although she can also get snake venom by killing the snake directly and taking out the snake gall, the amount of snake venom is too limited, and she is very interested in the venom of this little snake that she has never seen before, so she plans to keep it for the time being, so that there will be an inexhaustible supply of venom to use.

After taking the venom, she rolled up the little snake and put it into a cloth bag, which was tightly tied and hung around her waist, so that the little snake could not escape from her hands.

Continuing to walk along the rock wall, the vines and plants in front of him are growing more and more vigorously, Tang Yan does not doubt that this road will be a dead end if it goes on, from the perspective of the growth of plants, the reason why the further forward, the better the growth of plants, must be that there are things in front of them that help plants grow.

Because of the poisonous little snake she had encountered before, Tang Yan walked cautiously and vigilantly at this time, slowed down a lot, walked out of two miles and crawled out of a pile of vines, Tang Yan's vision suddenly brightened! This is the end of the narrow path, which is like a passage, and in the space in front of us, flowers and trees are flourishing, and butterflies are flying.

There are not many butterflies, less than 100, but each one is half a meter in size, and even the largest black butterfly spreads its wings about 1.5 meters long!

Butterflies with amazing heads flew and landed, and the place where they landed was on the round white stones between the flowers and trees in the cave, and the slender butterfly legs grabbed the stones to stabilize their bodies, and their long mouthparts like straws reached into the nearby flowers and trees to suck the nectar.

Beautiful butterflies look pleasing to the eye, but for these butterflies, Tang Yan doesn't think they are very good-looking, ordinary butterflies can't grow to this size at all, it can be seen from the body shape and habits of these butterflies that these butterflies don't grow up by sucking nectar normally.

The flowers and trees in the cave were too far away for Tang Yan to distinguish carefully, but there were several plants she knew, which were definitely toxins, and these butterflies fed on venom, which was definitely dangerous.

'Wow~' Not far from Tang Yan, a rustling sound sounded, and with the footsteps of stepping on grass and trees, there was also a person who led Tang Yan's eyes - Su Die!

She even walked out of that darkness? And I don't know where to find the exit, I also came to this cave, but Su Die and herself didn't walk the same way, so they walked out not far from the entrance of the cave where Tang Yan walked out.

Tang Yan saw Su Die, and Su Die naturally saw Tang Yan, the secret realm was deserted, and there were only four people who came in, but Su Die knew only three, Tang Feng, Long Yufeng, and herself.

Now that she suddenly saw Tang Yan, her eyes were filled with surprise on her face, and after a moment of surprise, she was still a little happy.

Crawling out of the hole covered with plants, she saw the butterflies growing here at first sight, although she admired the amazing size of the butterflies here, but after seeing Tang Yan, her first choice was to meet Tang Yan first.

For Tang Yan, it is not just as simple as giving her a place in the Four Kingdoms Competition, Tang Yan is also in the case of lack of qualifications when entering the secret realm, trying to ensure that her quota is not lost, if there is no Tang Yan, it is impossible for her to enter the secret realm, so now Tang Yan is a benevolent person to her.

"Be careful! Dodge! Tang Yan saw Su Butterfly walking towards her, and attracted two red and yellow butterflies on the side to stretch out their long mouthparts to her, and gave a prompt, but it was this voice that suddenly startled nearly a hundred giant butterflies to whistle and fly like crazy!

Su Die heard Tang Yan's voice and dodged the 'attack' of the two butterflies in time, but then more butterflies went in the direction of Tang Yan.

Tang Yan was not in a hurry, took two steps back and retreated back into the vine-covered 'passage', and the large number of butterflies seemed to have lost their goal for a while, and turned their heads towards the butterflies!

The overwhelming butterflies took off, and a shadow fell to cover Su Die's whole person, although she also has the word butterfly in her name, but she is not close to butterflies at all. The black butterfly led by the leader actually inserted the 'straw' directly into the head of the butterfly, such a move is enough to show that the butterflies here not only eat nectar, I am afraid that even animals and humans are within their prey range!

Su Die is also a master of the Martial King, at a critical moment, she swung her long sword, and cut off a piece of butterfly wings in an instant, and the pollen on the broken butterfly wings flew all over the place, so that Su Die had to squint her eyes, so as not to lose her eyes to the pollen, she kept in her hands, and continued to chop the giant butterfly that rushed towards her in the air, but soon, she found something wrong with her body, it seemed that because of inhaling pollen, her hands and feet became cold, and the side effect of her body was that her body was heavy.

"Go back!" At this time, Tang Yan's voice sounded like a wake-up again.
