"Wow! How can there be such a big clam with such a big clam! Is there a super large pearl in it?" Feng Luqi stared at the giant clam near the wall of boiling water at a glance, and there seemed to be a gold coin flashing in his eyes.

"Look for clues, find clues, don't keep thinking about treasures!" said the Demon Sword in protest against her greed for money.

"Of course I'm looking for a clue! Maybe there's a clue on the big clam!"

"What clues can there be? I don't think there's any other way to get into the caverns down there unless there's a rift in this area. ”

"Brother Jian's point makes sense! Mr. You Guang, I remember you said that the hot springs in this body of water are caused by water seeping into the magma layer from the cracks in the rock layer below, being heated and then gushing back up from the cracks. Sima Chengzhen was afraid that he would argue endlessly, so he hurriedly changed the topic, "So I think since we can't find any clues in the central area of the circle, we may be able to try the hot spring area on the periphery of the circle, where there must be cracks in the rock formations under each spring." ”

"But most of the fissures there go straight to the magma layer, and they are too far away from the central area of the circle, so it's unlikely that there will be a rift branch leading to the central area, right?"

Sima Chengzhen felt that what she said was reasonable, but he didn't know how to explain it for a while, and everyone else was also thinking, or observing the surroundings, looking for clues.

The Demon Sword squinted at the sword head and muttered for a long time, then suddenly glared at the round sword head and said, "Do you all think that there are no hot springs around here, and the wall of boiling water is completely formed by the heating of the fusion array eye?"

Everyone else nodded yes, and Mr. You Guang said suspiciously, "Could it be that Brother Sword thinks there may be other causes?"

The Demon Sword nodded at the head of the sword and said, "I think there is probably a hot spring in the surrounding wall of boiling water! It's just that the boiling water heated by the fusion furnace array obscures the existence of the hot spring." ”

Mr. You Guang's eyebrows jumped: "Oh, then how does Brother Sword think the hot spring you are talking about was formed?"

"Isn't the water in the center of the circle calm? It means that the water temperature here is much lower than the outer boiling water wall, and the closer you get to the center, the lower the water temperature becomes, so I speculate that there must be cracks in the center of the circle where cold water can seep into the magma layer below.

However, there is a cavern underneath this area, which causes the fissure to not go directly to the magma layer, but only to go around the top and edge of the cavern to the magma layer, where it is heated by the magma and then ejects out of the crack located in the wall of boiling water.

If there is indeed a hot spring in the boiling water wall, it will definitely be concentrated in the inner and outer areas of the boiling water wall. The Demon Sword said as he drew a schematic diagram in the void with a plastic energy spell, and when he said this, the schematic diagram was also finished, "Please sir, look at the picture, the crack where the cold water seeps down is relatively close to the hot spring located on the inside of the boiling water wall, and there is very likely a branch crack in the middle.

If my assumption is correct, then we can find a hot spring and go through the branch crack into the cold water seepage crack, and there may be branch crack connecting to the cavern, and we can enter it. ”

The schematic diagram of the Demon Sword drawn in the void with the Shaping Technique is very intuitive, as soon as he finished speaking, everyone else understood, Sima Chengzhen gave a thumbs up and said: "Brother Sword is really well-informed!

Feng Luqi flattened his mouth and said: "When I really find a hot spring in the boiling water wall, senior brother will praise him again, and then I will listen to senior brother, and in the future, I will talk less with him, and ask for advice with more humility." ”

"Hahaha, what Brother Jian said is penetrating, in this way, even in the central area of the magic circle, it is also possible to use the leaching mining method to extract the mineral subtleties in the magma layer and the underwater rock layer, and Mr. Xiangxiang's wisdom must be able to think of this plan. I'm very confident in Brother Sword, so let's go and have a look inside the wall of boiling water. "Mr. Yuguang harnesses the puppet and swims into the wall of boiling water.

It is said to be a wall of boiling water, but it is not like boiling water at all, but like black smoke, very similar to the boiling water spewed out of those chimney-shaped hot springs outside the circle, in fact, it is a hydrothermal flow mixed with many mineral subtleties, most of which come from the bottom rock that has been melted into magma by the eye of the fusion array, but if the speculation of the Demon Sword is accurate, and there are indeed hot springs in the thick wall of boiling water, then a considerable part of it will be immersed in the rock layer more than ten miles thick under the water, and the magma below.

According to the speculation of the Demon Sword, Mr. You Guang first drove the puppet to search for the inner edge of the boiling water wall, and the light beam was released from the barrier opened by the Xuanzhu furnace during the Qingming Dynasty, so that he could see clearly where the beam was shining, the bottom of the boiling water wall.

As a result, it took more than half an hour to complete a circle, and in order to search carefully, the puppet swam very slowly, and it can be seen that the circumference of this circular calm water in the center of the circle is at least thirty miles, but unfortunately, no hot springs were found, only magma rivers were seen flowing into a ring of rock at the edge of the boiling water wall.

This ring of magma has a tendency to condense, causing the calm circular area in the middle of the circle to gradually bulge around it, forming a structure similar to that of a crater.

Zhang Yuyun said: "It's too troublesome to find it like this! It's better to go up there, shine under the divine light of the Qingming Xuanzhu, and envelop the entire wall of boiling water, and you can see it at a glance." ”

Sima Chengzhen said: "Sister Waist forgot, before we came down, didn't we shine under the divine light of the treasure furnace on it, but we only saw the whole picture of the magic circle, and other than that, we didn't see anything else." ”

Zhang Yuyun said: "The treasure furnace and Mr. You Guang have the same mind, at that time he only wanted to see the whole picture of the array, so the treasure furnace only showed him the whole picture of the magic circle, if he wanted to see the situation at the bottom of the boiling water wall, the treasure furnace should show him." ”

"What Jade Waist said is reasonable, go up and try it. So Mr. You Guang drove the puppet to the height directly above the central area, and only stopped when he was close to the rock formation above, wanting to see the situation at the bottom of the boiling water wall below, but unexpectedly, the enchantment opened by the Xuanzhu Furnace did not shoot out the divine light as he wished this time, so he had to shake his head and said: "No, the Divine Furnace did not go as I wanted this time, but this makes me believe that there may be some secret hidden at the bottom of the boiling water wall." ”

The Demon Sword said: "It's better to use the five fusion array eyes in the inner ring of the magic circle as a reference landmark to start searching." ”

Mr. You Guang agreed with his proposal, so he thought about the location of the fusion array eye, and suddenly five divine rays of light shot out from the enchantment, just enough to illuminate the five array eyes, so he chose an array eye and drove the puppet to dive towards its location.

Through the divine light, you can see with the eye of heaven that around the eye of the fusion furnace array is a magma pool with a diameter of more than 100 steps, and there are rivers of magma coming out in all directions.

The puppet dived in front of the Fusion Furnace Array Eye, and said with a Demon Sword: "If there is a hot spring, it should be in the middle of the two magma rivers, and look for it along the magma river that flows to the inside of the boiling water wall, and pay attention to the area on both sides of it with divine light." ”

Mr. You Guang acted as he said, and drove the puppet to swim along a magma stream that flowed to the inner side of the boiling water wall, and two new divine lights also shot out above the barrier, surveying the areas on both sides of it, only to see that magma tributaries appeared from time to time along the way, and the tributaries of another magma river intersected and crisscrossed, forming a magma river network, so that the water temperature in various places in the boiling water wall would not have too much drop, of course, the water temperature of the inner and outer rings of the boiling water wall must be lower than the water temperature in the middle ring, and it will gradually decay until the boiling water wall has a boundary.
