Su Mi originally wanted to change her route and go back.
After all, she risked pushing the stone at the entrance away at this time. Once the stone fell into the water, it might cause turbulence and the stone would also hit her submarine.
But he was stopped by Ge Shanshan.
"Miss Su, I took a look at the surrounding terrain and water flow. With this situation and water flow direction, as well as the arrangement of light and shadow, if there is a volcano above, there should be more than one entrance."
Su Mi's eyes lit up.
Ge Shanshan is Lu Yishan's disciple. As long as it's geography, whether it's on the mountain or underwater, can it still stump her?
"But even if there is another entrance, how can we find it?"
“Although this entrance is blocked, the speed of the water here and the direction of occasional water vortex rotation are fixed.
Is there a temperature monitor inside the submarine? "
Su Mi nodded, "Yes."
"Let's go north."
Su Mi asked doubtfully: "To the north? But the temperature in the north will be getting lower and lower. The lower the temperature, the farther we are from the volcanic area."
"Actually, this is easy to explain. This kind of terrain is like a child playing a maze tunnel game.
It seems that the nearest one is blocked by a wall, but if you look far away, you can find a way out by just going around. Miss Su, you have to believe me, I made no mistakes in this regard. "
Su Mi also felt that what Ge Shanshan said made sense, so she followed Ge Shanshan's method and drove north, according to the temperature display in the submarine, to the north where the water temperature dropped.
But the road went further and further, and after half an hour, the entire dark river pool became brighter, and there were more aquatic animals in the river.
Fat white snake!
Su Mi remembered that she let Dabai out to play by herself. Why is it here?
As Su Mi approached, the Fat White Snake obviously sensed Su Mi's presence, and excitedly swam downstream from the distant underground river.
Ge Shanshan saw such a thick white fat snake swimming toward them, and her eyes widened in fear.
"Miss Su, hurry up, hurry up, there's a snake!"
Su Mi looked at the fat white snake wandering outside the submarine and smiled, "It's okay, it won't attack us."
Ge Shanshan looked at Su Mi dubiously, "But look at it, it seems to be spitting snake letters at us to threaten us."
At this moment, the fat white snake was very excitedly twisting its chubby white body outside the submarine, and opened its mouth, and half of the snake was trembling outside.
If you didn't know what it meant at this time, I'm afraid it would be a bit scary.
"It's okay. Look, didn't it just leave?"
The fat white snake expressed that it had eaten a lot of delicious food here, and was excitedly asking Su Mi if the owner wanted to eat.
Su Mi was worried that Ge Shanshan would be scared, so she asked Fat White Snake to leave first. But at the same time, through Fat White Snake, Su Mi also knew where they were now.
This is exactly where the downstream stream of the "Utopia" next to her col meets the underground river pond.
In other words, if you go further north from here, you can reach the forest next to the mountain col.
Su Mi had a vague hunch in her heart that if there really was another entrance and exit to the volcano area, Jiuye might not be locked up on the other side of the volcano long ago.
Thinking of this made her very dizzy.
The mess in the courtyard of her wooden house before was probably inseparable from Najiu.
Oh no! She put the giant python into the pond again.
Thinking of the giant python whose skin was peeled off by Jiu, Su Mi felt trembling in her heart. She was really worried that Jiu Xing would go crazy. Xiao Bai, Da Huang, and the monkeys were still in the col.
So she speeded up again, maximizing the speed of the submarine, but gradually the water level became shallower, and they drove the submarine out of the water.
"This" Su Mi looked at Ge Shanshan uncertainly, only to realize that she was looking at her surroundings with great curiosity and surprise.
"Miss Su, the environment here is really beautiful!"
"It's indeed good, but Shanshan, we are looking for the entrance to the volcano area, but now we are out of the water. Can you confirm the location again?"
"That's right, look at the entrance to the cave over there!" Ge Shanshan looked around, then pointed to the foot of the mountain at the bottom of the underground river, where there was an irregularly shaped cave entrance.
"You mean that's the entrance to the volcanic area?"
Ge Shanshan shook her head, "I'm not quite sure about this yet. But based on the temperature and current in the pool and the current topographic environment outside, it is very likely that the entrance to the volcanic area is at the bottom of this cliff."
"Then let's go ashore first."
Su Mi asked Ge Shanshan to go ashore first, while she drove the submarine back into the water, parked it, and stored oil and electricity in the submarine.
When Su Mi came out of the water, she happened to see Ge Shanshan lying on the ground near the entrance of the cave, looking at something.
At this moment, her hand was tapping one thumb horizontally to the ground at the foot of the mountain, and then looking at a certain point between the water surface and the entrance of the cave.
Su Mi didn't know what she was doing specifically, but it seemed like she was doing some simple address tests with her fingers.
"Miss Su, come and see."
When Su Mi saw Ge Shanshan suddenly shouting excitedly, she immediately ran over.
The water surface of this stream downstream is somewhat similar to the surface of the deep pool in S City. It is not very open, but the water is very deep, and it extends in all directions under the pool. If you are not very skillful, you may be in danger while crossing the underground river. Something happened.
And the water surface happened to be at the edge of the forest. Su Mi had to turn sideways to reach where Ge Shanshan was lying down.
She looked at where Ge Shanshan was pointing. The entrance to the cave was dark, "Is there nothing?"
"Oh, lie down on the ground and look forward in the direction of the top of my thumb."
Su Mi lay down next to Ge Shanshan, and then looked forward horizontally along the top of her thumb.
There is nothing there except a cave.
Moreover, Su Mi felt that this location seemed to be much hotter than the mountain col, and the hot air currents in the air were denser.
It's just that Su Mi really couldn't tell if there was anything.
"Miss Su, look below the entrance of the cave."
Su Mizai stared at the entrance of the cave carefully.
"There's nothing weird about it except that it's a little darker."
Ge Shanshan said calmly: "The entrance to the cave is very small, and it seems that we can't get in. But the color at the 90-degree right angle between it and the water surface is much darker than the water surface. This shows that there is still something below the entrance of the cave. There is a section of the entrance that is underwater, and the one above is just a small part of the cave entrance."
Su Mi nodded, "That's it."
"But are you sure? Is this cave entrance really the entrance to the volcanic area?"
Ge Shanshan nodded desperately, "Miss Su, I'm sure! Look carefully at the changes in the water surface at the entrance of the cave, and the air above the water there."
Su Mi stared at the area one by one.
Sure enough, she also discovered the clue.
The water was obviously flowing outward from the cave, and there was a faint yellow residue in the water.
"Huh? The water coming out of the cave still has smoke on the surface."
