"What are those glowing bugs, fireflies, how do they look like mosquitoes?" Xu Xiaoyuan was full of curiosity about this glowing underground world, and when she saw such a shocking scene, she even changed her tone of voice because of excitement.

"Those things are supposed to be luminescent mushrooms, which are glowing mosquitoes that generally live in underground burrows." Chen Ziyang replied.

"Mosquitoes?" Hearing these two words, Xu Xiaoyuan's excitement suddenly decreased a lot, after all, mosquitoes are not very good in people's impressions, even if the species that can glow looks so beautiful, but the word mosquito alone has greatly reduced the beauty of this insect.

At this time, this kind of flying insect has become like that in Xu Xiaoyuan's eyes, it is not a big deal. So she turned her attention to the mushrooms that glowed.

If you look closely, there are many types of mushrooms that glow around a few people, and there are two or three at a cursory glance, and the most conspicuous one is a mushroom with a very flat umbrella.

The mushroom's umbrella does not emit light, but rather the stipe that supports the fungus, and some green light that is stronger than the other luminescent substances emits from these stiles, illuminating the underside of the umbrella with green light.

Even more cute is a spherical mushroom, this mushroom glows with a mushroom umbrella, and the lilac light emits from the mushroom umbrella, which looks like a purple steamed bun.

Just when Xu Xiaoyuan looked at these mushrooms with admiring eyes, within the scope of her gaze, suddenly the umbrella of a purple big-headed mushroom broke, and some purple fungus spores emitting a faint lilac light were sprayed out of the breach, floating into the distance like a burst of smoke emitting purple light, and most of them fell into the lake.

Seeing this mushroom that was breeding, Chen Ziyang knew that the strange smell that was mixed in the air in this underground world should be the smell of these mushroom spores.

It seems that this underground world has existed for many years, and it is very likely that a delicate ecological balance was formed here before Yuan Tiangang set it up as a treasure hiding place, and it has continued until now.

However, Chen Ziyang did not have Xu Xiaoyuan's leisurely elegance, he took out the compass and kept calibrating the direction.

Chen Ziyang had a bold guess, he felt that Yuan Tiangang's treasure hiding location was likely to be directly below the formation composed of nine armors.

The reason is very simple, the iron frame sticking out of the nine armors pierces straight into the ground. For thousands of years, those iron shelves have been infusing mana into the armor, so if you think about it, there must be something remarkable underneath the nine armors that can continuously provide mana, and it is very likely that it is the location of Yuan Tiangang's treasure.

So on the way here, Chen Ziyang marked the direction of the nine armors early, although the mountain crack twisted and turned, and the direction of everyone's progress had changed many times, Chen Ziyang could still judge that the nine armors should be directly below the other end of the lake.

The outlet of the mountain crack when they came was next to the lake, and there was only a small flat area between the exit and the lake, except for this small area, which was relatively flat, and the rest of the place was an upright rock wall around the lake.

The area of this lake is really not small, even if the top of the entire underground space is covered with glowing plants, and there are a lot of glowing mushroom mosquitoes flying around on the surface of the lake, but there is still no end to the lake.

A few people had come from the Nine Armors, and the cracks in the mountain were very long, so it seemed that there was still a long way to go if they wanted to reach directly below the Nine Armors, and maybe they would have to cross the entire lake.

Just when Chen Ziyang was thinking about whether this underground lake was safe, how deep the water was, and how a few people should cross it, Shangguan Kangning also found something.

The large glass bottle containing two ground green insects was held up on the palm of Shangguan Kangning's hand. Since coming here, the two timid bugs have curled up in a ball, almost motionless, and it is obvious that the ancient city hidden in this vicinity is very threatening in their eyes, so the two timid bugs have never raised their heads.

But once they entered this glowing underground world, the state of the two bugs was completely different.

The two little ones raised their tentacles again, shaking in the same direction. This state had appeared once before, and that was when everyone approached the location of Yuan Tiangang's treasure.

It seems that for these two ground green worms, the attraction of what attracts them now is much greater than the threat posed to them by these insects or Gu worms around them, so these two timid guys completely ignore the surrounding situation, and want to crawl in that direction.

After communicating with Shangguan Kangning for a while, Chen Ziyang learned of Shangguan Kangning's speculation, and there was a great possibility that it was the female worm of the Sun and Moon Nose Worm that caused the two ground green worms to move.

Because of the relationship between passing through the thick mountain wall and coming to the underground, the smell of the female worm of the sun and moon nose worm should be more obvious, after smelling this smell, the two ground worms finally couldn't hold back, and the desire for food had overcome their fear.

After looking at the direction of the two earth green insects, Chen Ziyang looked at the compass in his hand again, the two directions were completely the same, it seemed that his guess was not wrong, the treasure left by Yuan Tiangang should be in that direction.

The surface of the lake is filled with a hint of white mist, and it seems that the temperature of this hot spring lake is not low. From time to time, you can see some fish with their tails out of the water, make a splash and then disappear below the surface, since there are fish here, then the water in the lake should be safe.

When he stepped into the lake for the first time, Chen Ziyang shivered, and the warmth from his feet gave him a hint of warmth, and he actually felt like taking a bath under his feet.

I don't know if it's because of the black rock formations under the water, or because the light source here is not bright enough, the whole lake looks black, like a dark mirror.

The glowing plants on the top of the underground space and the glowing mushrooms flying on the surface of the water reflected on the surface of the lake, making the six people walking through the lake feel that they were walking in space, and those dots of light were countless glowing stars.

Because they didn't know the depth of the lake, a few people could only walk forward slowly and tentatively. Yang Lei and Umbrella Shishuai walked at the front of the team, using the sapper shovel in their hands as a detector to detect the depth of the water, and kept touching the bottom of the lake again and again with the sapper shovel.

The water level of this underground hot spring lake is not very deep. At first, when a few people entered the lake, they walked along the bottom of the lake with a small slope, and the water level soon reached their waist, but since then, the water level has basically stopped rising, and the bottom of the lake is like a flat river, and the slope changes very little.

Chen Ziyang used the compass to calibrate the direction of the team, while carefully checking the surroundings, although the water of this hot spring lake is not deep, it is not guaranteed that there will be some Gu worms arranged by Yuan Tiangang inside, maybe danger will come inadvertently.

"Leizi, don't move!" Just when Chen Zi Yang Dong was looking west, suddenly the voice of Umbrella Shi Shuai came from the front, he heard caution from Umbrella Shi Shuai's tone, obviously something bad had happened, and then he looked in the direction of Yang Lei.

Below the surface of the water, there is a small object with white light that is constantly rotating around Yang Lei's waist, as the object swims under the water, the circle drawn by this thing is getting smaller and smaller, getting closer and closer to Yang Lei's waist, and it is about to touch together.

Yang Lei was already frightened, he didn't know what to do with the sapper shovel in both hands, he could only listen to the words of the umbrella Shi Shuai, and stood there quietly.

After staring at the object for a few seconds, Umbrella Stone Shuai made a fierce effort and slapped the sapper shovel in his hand towards the glowing object.

But I don't know if it's because of the refraction of light under the surface of the water, his shovel turned out to be crooked, and when the shovel of the umbrella stone shuai slapped into the water, the glowing object happened to have just passed.

But Umbrella Shishuai's reaction was very fast, he saw that his shovel was empty, so he immediately rotated the shovel 90 degrees in the water and lifted it upwards violently.

The head area of the sapper shovel is very large, and the strength used by the umbrella stone shuai is not small, he actually brought up a large area of lake water, and the luminous object that is not very large was also brought out.

Immediately afterwards, Umbrella Shishuai caught the object that he had taken into the air with a sapper shovel. As soon as it landed on the surface of the shovel, the glowing object kept flapping and struggling. After a few people came over, they realized that they had made a big joke.

"Oh my God, it's beautiful!" Xu Xiaoyuan shouted in surprise.

This glowing object was not a Gu worm, it turned out to be a glowing fish. The fish is about three inches long and has a fusiform body. What made Xu Xiaoyuan excited was not that this little guy could glow, but that the whole body of this fish was transparent.

Except for a long black area on the bottom of the belly, which is presumably the intestines of the fish, the whole fish seems to be made of milky white silicone, and the other side can be seen directly from one side of the fish's body, and it is very clear. Even the bones of this fish can be counted clearly.

"Okay, this fish looks really good, if you get sick or something, if you go to the hospital for an examination, you don't even need to take an X-ray, you can see it clearly." It may be that seeing that he was scared enough by such a small thing, Yang Lei was full of complaints, and even the fish were damaged.

Under Xu Xiaoyuan's repeated strong request, several people only took a few glances at the transparent fish, and the fish was released by Umbrella Shishuai.

"This place is really interesting, mosquitoes will glow, mushrooms will glow, and now even fish will glow, I don't know if the treasure left by Yuan Tiangang will shine."

When she said this, Xu Xiaoyuan's eyes were full of golden stars. The beautiful scenery and strange creatures in front of her made her full of unknown curiosity about this place, and Xu Xiaoyuan had already regarded this treasure hunt as an adventure, and she was very interested.

As we move on, there are more and more transparent fish that glow beneath the surface, and it seems that these fish like to revolve around things moving in the water, and from time to time a few swim to the side of everyone. At most, everyone is surrounded by two or three of these glowing fish.

Although walking in the hot spring lake is a relatively pleasant thing, it is not very comfortable to soak in the water for a long time, especially in the water with clothes on, and it is still more laborious to walk in the water, and after walking for a long time, several people are very tired.

After calculating the distance, Chen Ziyang estimated that they should not be far from the nine armors directly below, and just as he was thinking about when he would be able to reach his destination, suddenly he saw that the water in front of him was a little different.

The water was very dark, and there was no light at all.

Although the surface of the hot spring lake is also black, the light spots formed by the glowing plants on the top of the underground space are still reflected on the surface of the lake, but there is not even a single point of light in that area, and the only thing that glows is some glowing mosquitoes flying above the area, and it seems that there is no lake water there.

After walking forward for a distance, Chen Ziyang saw that it was not the people who had passed through the entire hot spring lake and reached the other side, but they had encountered an island in the middle of the lake.

Seen from the black outline, the island looks like a huge mountain protruding from the water, and it is not small in height or size.

"Be careful, we may have walked to the place, I smell the breath of a Taoist formation." Jin Huang reminded carefully behind Chen Ziyang.

At this time, Yang Lei's eyes were full of essence, and he was eager to try, looking at him as if he wanted to rush to the island in the middle of the lake as soon as possible to find the treasure left by Yuan Tiangang.

The six of them unanimously sped up their speed, and soon, they landed on the island in the middle of the lake.

While several other people were busy drying their bodies, Chen Ziyang kept searching. Since he landed on this island in the middle of the lake, it was very obvious that he felt a Taoist aura, which should be similar to what Jin Huang said about smelling the aura of the formation.

After climbing a protruding rock, Chen Ziyang leaned down to look down, and in a relatively low-lying place, he vaguely saw nine straight black lines connecting there.

"Found it." Obviously, the nine straight black lines are the nine iron bars sticking out of the armor.

After running a few steps in the direction of the nine iron bars, Chen Ziyang saw that in addition to the nine iron bars, there was also a pitch-black sword inserted in the center of the nine iron bars, exuding a simple atmosphere.
