In this apocalyptic world, when everyone is starving, I have a storage space full of supplies.

Su Mi originally wanted to go back in another direction.

After all, at this time, it is risky to push away the stone at the entrance. Once the stone falls into the water, it may cause turbulence, and the stone will also hit her submarine.

But Ge Shanshan stopped her.

"Miss Su, I took a look at the surrounding terrain and water flow. With such a situation, the direction of the water flow, and 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 master apprentice, as long as geography, whether it's on the mountain or underwater, can it still be difficult for her?
"But even if there is another entrance, how do we find it?"

"Although the entrance is blocked, the speed of the water flow and the direction of the occasional water vortex rotation are fixed here.

Are there temperature monitors in the submarine? "

Su Mi nodded, "Yes."

"We're heading north."

Su Mi asked suspiciously: "To the north? But the temperature in the north will get lower and lower. The lower the temperature, the farther we are from the volcanic area."

"Actually, it's easy to explain. This terrain is like a child playing maze tunnel game.

It seems that the nearest one is blocked by a wall, but looking far away, you can find a way out by going around instead.Miss Su, you have to believe me, in this respect, I have made no mistakes. "

Su Mi also felt that what Ge Shanshan said was reasonable, so she followed Ge Shanshan's method and headed north, according to the temperature display in the submarine, heading to the north where the water temperature dropped.

It's just that the road got farther and farther away. Half an hour later, 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 she here?

As Su Mi approached, the Fat White Snake obviously sensed Su Mi's existence, and excitedly moved downstream from the dark river in the distance.

Ge Shanshan saw a thick white snake swimming towards them, her eyes widened in fear.

"Miss Su, hurry up, there are snakes!"

Su Mi looked at the fat white snake hovering 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 threatening us by threatening us."

At this moment, the fat white snake was twisting its chubby white body outside the submarine with great excitement, and opened its mouth, half of which was trembling outside.

If you don't know what it means at this time, I'm afraid it's really scary.

"It's okay, look, isn't it leaving now?"

The fat white snake expressed that it ate a lot of delicious food here, and was excitedly asking Su Mi, the owner, if he wanted to eat it.

Su Mi was worried that Ge Shanshan was afraid, so she asked Fat White Snake to leave first.But at the same time, through the fat white snake, Su Mi also knew where they were now.

This is the location where the downstream of the "Xanadu" stream next to her col meets the underground river pond.

That is to say, from here to the north, you can reach the forest next to the col.

Su Mi had a faint premonition in her heart. If there really was another entrance to the volcano area, Jiu would not have been closed at the volcano long ago.

Thinking of this made her very dizzy.

The mess in the small courtyard of her wooden house before may have something to do with Na Jiu.

Oh no!She put the giant python in the pond again.

Thinking of the giant python whose skin was stripped off by Jiu at that time, Su Mi felt chills in her heart.She was really worried that those nine hungry people would go crazy, Xiaobai, Dahuang, and the group of monkeys were still in the depression.

So she speeded up again, bringing the speed of the submarine to the extreme, but gradually the water level became shallower, and they just emerged from the water while driving the submarine.

"This..." Su Mi looked at Ge Shanshan incredulously, only to realize that she was looking at the surrounding environment very curiously and pleasantly.

"Miss Su, the environment here is really beautiful!"

"It's really good, but Shanshan, we are looking for the entrance of the volcano area, but now it's out of the water, can you confirm the location again?"

"It's not wrong, look at the entrance of the cave over there!" Ge Shanshan looked around, and 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 sure about this yet. But according to the temperature in the pool, the water flow, and the current topographical environment, 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 and parked it, and stored fuel 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 and looking at something.

At this moment, her hand is tapping a thumb level on the ground at the foot of the mountain, and looking at a point on the water and the mouth of the cave.

Su Mi didn't know what she was doing, but it seemed that she was doing some simple tests on addresses with her fingers.

"Miss Su, come and see."

Seeing Ge Shanshan shouting excitedly suddenly, Su Mi ran over immediately.

The water surface in the downstream of this stream is somewhat similar to the surface of the deep pool in S City. The opening is not big, but the water depth is very deep, and it extends in all directions under the pool. accident.

And the water surface happened to be at the very edge of the forest, so Su Mi had to turn her body sideways to get to the position where Ge Shanshan was lying on her stomach.

She looked at the place Ge Shanshan was pointing at, and the hole was pitch black, "There's nothing?"

"Oh, you lie on the ground and look forward in the direction of the apex of my thumb."

Su Mi lay down next to Ge Shanshan, and then looked forward horizontally from the top of her thumb.

There is nothing but a cave over there.

Moreover, Su Mi feels that this location seems to be much hotter than the col, and the thermal air in the air is also denser.

It's just that if there is something to say, Su Mi really can't see it.

"Miss Su, look at the bottom of the cave entrance."

Su Mizai stared carefully at the bottom of the cave entrance.

"Apart from the fact that the color is a little darker, there is nothing strange about it."

Ge Shanshan calmly said: "The entrance of the cave is very small, and it seems that we can't get in. However, the color at a 90-degree right angle between it and the water surface is much darker than the water surface, which shows that there is still water below the entrance of this cave. One part of the entrance is underwater, and the upper part is just a small part of the hole."

Su Mi nodded, "I see."

"However, are you sure? Is this cave entrance really the entrance to the volcanic area?"

Ge Shanshan nodded desperately, "Miss Su, I'm sure! You should carefully observe the changes in the water surface at the entrance of the cave, as well as the air above the water surface there."

Su Mi followed suit one by one and stared at the piece.

Sure enough, she also discovered the clue.

The water was clearly flowing out from the cave, and there was a faint yellow residue in the water.

"Huh? The water that comes out of the cave still smokes on the surface of the water."
