After reaching the inner edge of the boiling water wall again, he still didn't find any hot springs, and Feng Luqi teased the Demon Sword and said, "Look, your speculation is going to go bankrupt, you won't start from another fusion furnace array and find another magma river to explore, right?"

"It's too early to draw conclusions, the outer ring of the boiling water wall hasn't been explored yet, and the cracks that seep down shouldn't be too close to the hot springs." ”

"Well, that makes sense! After all, the water in the center of the circle is to bypass the hidden cave below and seep into the magma layer, which means that the crack it flows through is very close to the rock layer below the inside of the boiling water wall, and may even extend there, if there is a hot spring on the inside of the boiling water wall, the water crack will be very close to the upper water crack, and the seeping water may not reach the magma layer, it will be heated by the nearby hot spring and gush up, so that the hot spring on the inside of the boiling water wall will soon dry up, so if there is a hot spring in the boiling water wall, it should be on the outside. Mr. You Guang seconded.

"Sir's analysis is very good, I didn't think it through at first, please go back to the eye of the fusion furnace just now, and then find a magma river to explore the outside of the boiling water wall. The Demon Sword of the Xiang Xiang said to Feng Luqi: "Look, even your new mentor supports me, what else are you not convinced? ”

Feng Luqi flattened his mouth and said: "Hmph! Shao Yise, when you explore the outside of the boiling water wall, you really find the hot spring, you can be proud again!"

While he was arguing, Mr. Yuguang had already harnessed the magma river that the puppet had come from to return to the fusion furnace array, this time because he didn't need to explore, he went back in less than a cup of tea, and then he probed along an outflowing magma river, and shot two beams from the barrier to illuminate the areas on both sides of it.

This time, after traveling for about five miles, he found a large chimney-shaped hot spring, and the Demon Sword happily rushed up: "Haha, do you see? What did I say? Now take it, do you remember how you promised Brother Sima? Don't talk in the future, you must always humbly ask me for advice, haha!"

Feng Lu Qi flattened his mouth: "Hmph! Look at you proudly." There is no problem this time, and I will ask you for advice next time!"

When Mr. You Guang took advantage of his two mouths, he turned the puppet into the size of a tadpole and dived in from a hot spring, the situation along the way is the same as diving into this underground water area from the hot spring at the bottom of the mine, Mr. You Guang said: "This place is more than ten miles away from the center of the circle, it is unlikely that there will be a horizontal crack leading to that side, it seems that we have to pass through the magma layer." ”

"Great! You can see the magma layer!" Zhang Yuyun clapped his hands.

This crack is generally relatively straight, the puppet dived for nearly twenty miles, and finally broke out of the crack, but the first thing he saw was not the fiery red hot magma, but entered a layer of black smoke, Mr. You Guang used the eyes of the sky to see the black smoke illuminated by the divine light of the enchantment, showing its microscopic structure, but it was a subtle mixture of water and mineral subtlety, similar to the black smoke emitted from the hot spring.

At the same time, the eye of the sky also saw that the temperature of this black smoke was four or five times that of ordinary boiling water, in modern scientific terms, it was four or five hundred degrees Celsius, called supercritical water, which is the density of water that expands due to high temperature and the density of water vapor that is compressed by high pressure is exactly the same as water.

There is no difference between the liquid and the gas of this water, which is completely blended together to become a fluid that presents a high-pressure and high-temperature state, and can dissolve many substances, including almost all metals, and even gold.

If there is no enchantment propped up by the Xuanzhu Furnace of the Qingming Dynasty, the puppet may not be able to resist the erosion of supercritical water, but with the realm of Mr. You Guang, it should be able to resist with defensive spells such as light, barrier suit, and qi ban.

Zhang Yujiao said disappointedly: "Oh, I thought I could see magma, how could it be black, the same as when the crack under the spring passed through......"

"Hehe, this layer of black smoke is the water heated by magma, it is the hot spring eye that spews out it, it is made of the subtlety of water mixed with the subtlety of minerals, under this layer of black smoke, it is magma, I don't believe me will use the light of the divine furnace to show you. Mr. Yuguang let the enchantment shoot a divine light down, and sure enough, a fiery red magma shone out, and bubbles of air bubbles swelled and shattered on its surface.

The Demon Sword said with emotion: "Although I only saw a small piece of the divine light, it is not difficult to imagine the appearance of a large area of magma, and the scene of purgatory is probably nothing more than that." ”

"I guess there's a hot spring like the bottom of the mine in that cavern, or maybe it's filled with this black smoke, and we just have to go to the bottom of the rock formation below the waters in the center of the circle to find the crack. As he spoke, Mr. Yuguang had already harnessed the puppet to move towards the waters in the center of the circle, and at the same time let the enchantment release divine light to search the rock formations above, looking for cracks in the black smoke gushing up.

Feng Luqi suddenly said very humbly: "Mr. Jian, do you think that cave is like the bottom of the mine, or is it full of black smoke?"

The Demon Sword was a little surprised and unaccustomed for a moment before he said, "Uh...... Well...... I guess there will be a lot of fumaroles inside, and if there is water seeping down and flooding the fumaroles, it may also form hot springs, but not as many as at the bottom of the mine, after all, there are no aquifers underneath the caves, only black smoke layers across the rock formations. And seeing that the water above the cave is so calm, I guess that the rock formation above the cave is connected to the cave without cracks, so the cave should be filled with black smoke. ”

Mr. You Guang nodded again and again: "Well, it makes sense, the whip penetrates, the analysis is too good, the Green Qi Fairy should indeed maintain an open attitude in the future, and ask Brother Sword more!"

"Since Mr. and Senior Brother Sima both said so, then I will really regard Mr. Jian as a mentor in the future, and Mr. Jian will please accept my worship. Feng Luqi said, and really bowed to the Demon Sword.

The Demon Sword was uncomfortably adaptable for a while, and said uncomfortably: "Uh...... Well...... Actually, you don't have to be too humble and humble, suddenly becoming like this, I really can't adapt to it, hehe. ”

On the way to the rock formation below the cave, the enchantment divine light revealed that there were many cracks in the rock layer above, but when you look at it with the eye of the sky, there is no water area that can connect to the rock layer.

This is of course in line with what is seen in the upper waters, and if these cracks can connect to the upper waters, then there will be hot springs in the middle ring of the boiling water wall, when in fact, a large number of hot springs will appear in the outer ring of the boiling water wall.

After exploring seven or eight miles like this, Mr. You Guang had been looking at the rock formations above, and suddenly the black smoke in the eye of the sky disappeared without a trace, replaced by fiery red magma, he hurriedly looked around, only to find that the puppet had unconsciously fallen into the magma encirclement.
