"Be quiet Jessica glanced at TSOK angrily, then said thoughtfully: "this monster... If I guess correctly, it should be a kind of source beast called" lava beast ". This source beast has always loved to haunt and live near the magma, especially good at team cooperation and predation. It is a kind of bottom species with not very strong individual strength..."

Speaking of this, Jessica turned her tone and continued with some doubts: "but the lava beasts you and I met today are not only much bigger than those in the legend, but also equal to the middle class practitioners of level 30 or 40... This is the final crux of what I didn't think about!"

Cao Ke laughed and said, "what's the matter with this? Perhaps, this lava beast is just like the snow gall ice toad we met a few days ago. It has a long time of cultivation, and its size and strength are naturally bigger and stronger than those of other similar animals! "

Jessica thought for a moment, shook her head and said, "it's not that easy! Although the source beast is a special product in the mainland of sirmir, the number of it is not large. Under the pressure of the major ethnic forces, the living space of the source beast is gradually shrinking. Therefore, in recent hundreds of years, it has been very difficult for people to see the source beast again, let alone those high-level source beasts with high cultivation. How much do they cherish, Even if it's rare to describe it, it's not too bad! "

"But this time we came out to follow the Dragon tribe. After we got close to the orange plain, we met the source beast twice. And the source beast we met in these two times either had high accomplishments or had some variation... There must be some potential connection in it!"

Cao Ke waved his hand and said, "OK, why do you waste your brain cells for these irrelevant animals? Our main purpose this time is dragon! This is the most important thing we need to understand and explore According to my estimation, this day is about to light up. If we don't go back soon, we'll meet the dragon clan! "

"Well." Jessica answered softly and simply cleaned up her mood. Then she was ready to go to Caoke and leave the valley with Caoke.

But just as Jessica turned around, her eyes inadvertently swept to the magma pit where she was attacked. At this time, there was no more magma in the magma pit, and the bottom of the pit was completely exposed to the air.

The magma pit is seven or eight meters deep, which makes Jessica feel a little strange. The shape of the magma pit is not the normal shape of the pot bottom, but a shape closer to the shape of the spoon. The four walls are smooth as a mirror, and slanting straight towards the center of the bottom. At a glance, it looks like a huge cone, and it goes into the ground upside down.

"Why?" Jessica seems to have found something, straight down, squatting on the edge of the magma pit, looking directly at the bottom of the pit.

Cao Ke originally summoned a unicorn fireball to light up the rock climbing and hurried back to his camp. However, when Jessica squatted down there without warning, Cao Ke naturally stopped his work.

"Ah! I said, "little KAKA!" Cao Ke was a little impatient and said, "what are you still doing there? Let's go! I'm ready for that. "

Jessica turned her head and waved to Cao Ke excitedly: "Cao Ke, come and have a look. There is no magma in this magma pit. You can see it at a glance!"

Cao Ke's face was bitter, but he had no choice but to step forward and walk towards Jessica, whining: "little Kaka, I know you are powerful! You just jumped out of this magma pit, which has already shaken away the magma in the pit! Without magma, the bottom of the pit will be exposed naturally! I admit that your strength is not strong enough? But we have to leave here now. If we don't go any more, we won't come... "

Before he finished speaking, he stopped abruptly, because Cao Ke also came to the edge of the magma pit and clearly saw the bottom of the magma pit.

"This... This... This..." Cao Ke's expression was surprised for a long time, and there was no reason for "this". Instead, Jessica squatted aside, raised her hand to the bottom of the magma pit, and said with a smile: "see? What's the purpose of that small cave there? "

Looking in the direction Jessica pointed out, you can see that at the bottom of the inverted cone-shaped magma pit, a dark hole is emitting hot gas! The hole is not big, and its diameter is about one meter, but the depth of the hole is unknown, because from the position of Caoke at this time, it seems that the red of magma is shining in the deep inside of the hole!

After observing for a long time, Cao Ke turned his head and asked Jessica, "little Kaka, don't you think this hole connects the real source of magma?"

"Smart!" Jessica excitedly hit a finger ring: "originally, when you and I just arrived at the bottom of the valley, we could only see a piece of ice and a piece of magma, but we could not see what was under the ice and magma. Therefore, we would take it for granted that these ice and magma were originally there, so we ignored their real source!"

Cao Kewei frowned and said: "now, because of your unintentional action, the magma in this magma pit dissipates, and the bottom of the pit is exposed in front of our eyes. From the shape of the bottom of the pit, it is not the kind of container responsible for carrying magma, but more like an exhaust pipe! The small cave at the bottom is the channel connecting the real source of magma and the surface. The real source of magma depends on these small caves and the conical magma pit to discharge the excess magma to the surface! "

"Exactly so!" Jessica took over CaO Ke's words again and said, "if you contact the initial judgment you made when you first saw this strange environment of ice and fire, can we conclude that there is still a huge space under the bottom of the Great Rift Valley! In this huge space, the underground magma competes with another mysterious ice source that does not know the source. The two kinds of energy squeeze and attack each other, and the burst out energy accumulates continuously... "

"Finally, the huge underground space is full of energy from the confrontation between ice and fire. There is no way but to evacuate energy to the surface to maintain the continuous stability of the underground space!"

"And the magma pit in front of us is a channel for the underground space to disperse magma energy! The ice and magma all over the valley, that is, the extra energy emitted by the two opposing sides of ice and fire in the underground space! "

After analyzing them like this, they looked at each other for a long time. Cao Ke swallowed a mouthful of foam and looked at Jessica. He said meaningfully, "little Kaka, does our judgment and conclusion sound a bit arbitrary?"

Jessica shook her head firmly and said, "no! This strange phenomenon here does not coincide with our judgment! In my opinion, even if there is some discrepancy between the facts and our judgment, there will never be much difference In fact, it's very easy for us to figure out this matter. I think the small cave at the bottom of the pit should be enough for a person to pass easily. Let's climb down the small cave and have a look. Isn't the answer clear? "

"Climb... Climb down?" Jessica's bold proposal, obviously far beyond the expectations of Cao Ke: "little Kaka, are you Elves as bold as you think and do? Climb down? If there is an independent space under this small cave, the temperature in it is definitely not comparable to that in the valley bottom! "

"If you think about it, even the excess energy emitted by them can form such a drastic temperature change at the bottom of the valley. If you and I go directly into that space, it's almost unimaginable to bear it!"

Jessica glanced at Cao Ke with disdain and disdain, and said, "don't you human beings have a famous saying‘ If you don't go into the tiger's den, you'll get the tiger's son. "There's no way to uncover the truth of some things if you don't take some risks! For example, the dragon people may not have thought that there is another cave under the ice and magma, or they may have thought of it, but they dare not go down there in person like you. That's why they have been here for such a long time and still have nothing to gain! "

"Moreover, Cao Ke, don't forget that the dragon clan is attracted by the vision at the bottom of the valley. Maybe their real purpose lies in the underground space! As long as we can get into that space and explore it, we will find something! "

When Jessica said this, Cao Ke was really moved by her. After all, the ultimate goal of Cao Ke's trip is to find out the real intention of the dragon clan. Now, a great opportunity is placed in front of him. It's a lie that he can't move his heart!

However, the things that zouk considered are obviously more comprehensive and complete than those of Jessica. First, the conclusion of underground space is just a judgment of him and Jessica. Whether it really exists is still between two theories.

Second, the urgency of time. After dawn, the next wave of dragon search teams will come down to the bottom of the valley. If Cao Ke and Jessica do not leave immediately, there will be a great risk of exposure.

Third, the uncertainty of the underground space. Even if the underground space really exists, as Cao Ke said, the degree of danger in it is absolutely not low. If they want to go in, are they ready to resist the unknown risks?

As for the end, of course, it's the members of the killing star and Muling who stay on the top of the Great Rift Valley. If Cao Ke and Jessica don't come back all night, you can't help worrying. Once they can't calm down and rush down the Great Rift Valley to find out, the result is what Cao Ke doesn't want to see
