On the ground around the lava lake, a large five-pointed star envelops the lava lake. The five black-robed people stood on the top of the five-pointed star, holding something in their hands.

"Your Excellency, you're ready." One of the black-robed ones reported.

"Let's get started." Yu said.

The five of them glanced at each other, and after confirming that they were ready, they silently counted a few times and placed the soul stone in their hands on the apex of the pentagram at the same time. Then several people hurriedly ran away while the pentagram had not yet reacted.

Not long after the black-robed man left, several bubbles appeared in the magma lake, which was still calm just now, and the bubbles burst after struggling a few times, and yellow sulfur gas was released from the bubbles. As the bubbles mounted, the dark red magma was churned and tumbled.

Soon the lava lake was boiling over, and the dark red surface of the rock began to reced, replaced by brighter and more vivid magma.

When the magma lake boiled to the extreme, the five-pointed star circle surrounding the entire magma lake suddenly lit up, and then it was violently closed, and there was no trace on the ground, and all the material carrying the five-pointed star was attracted by a mysterious amount, and the whole shrank to the center of the magma lake.

With the disappearance of the pentagram array, the boiling magma lake suddenly burst, and the chaotic power began to be guided in a specific direction, and the entire magma lake slowly rotated in this mysterious force, and it turned faster and faster, faster and faster, like a windmill blown by a strong wind......

Then, a huge whirlpool appeared in the center of the magma lake.

"Summon: Fire Elemental Lord." Yu stretched out his hand and threw a card towards the center of the vortex, and the 5 soul crystals on the ring were darkened at the same time, and a huge fire element was summoned!

As soon as the fire element appeared, it was firmly attracted by the vortex under its feet, and countless chains of flames flew out of the magma lake, directly binding it tightly, and there was no room for struggle at all.

"Upper left steady."

"Upper right steady."

Bottom Left ......

"The vertex is stable. My lord, it worked. After the black-robed people repeatedly confirmed from the beginning, a smile finally appeared on their faces, and the black-robed man who took the lead came to You's side to report the good news.

"Well, I saw it." You just nodded, and even a word of praise was stingy, but even a few black-robed people seemed very happy, and their expressions were much more relaxed than before.

The vortex became slower and slower, gradually reaching a constant speed, and the Fire Elemental Lord, who was firmly trapped in the middle of the vortex, did not even have room to struggle, and was completely unable to resist when he was tightly bound.

When the equilibrium was formed, the mountain wall behind the lava lake suddenly shook, and a boulder slowly moved away, revealing an upward passage.

Several black-robed men entered the passage without hesitation.

……

The small hill not far behind the black-robed man is very close to the magma lake, and you can clearly see the situation on the other side of the magma lake.

But on the other hand, the light here was much dimmer than that of the magma lake, and the large and small rocks along the way blocked the view from the side of the magma lake, which also allowed Chen Yin and the others to hide here safely and undiscovered.

"Gone. Look! They're gone. Lancelot, who was squatting on the ground, gently touched Chen Yin with his elbow and whispered.

"There's still time anyway, so let's wait a minute." After speaking, Chen Yin turned back to Angel and asked, "Holy Maiden, look at the way they started the magma lake just now, they seem to be very experienced, do they have more information in their hands than yours?" ”

"I don't have any information on that." Angel shook his head, "As for the information...... They are actually easier to collect than I am. ”

Angel's words seemed a little contradictory at first glance, but Chen Yin knew that she was actually doing well. As the opponent of the Holy Light Church for many years, the Shadow Church still attaches great importance to intelligence work, if the information is not well-informed, as a weak party, the Shadow Church should have been extinguished by the Holy Light a long time ago.

So in general, as long as the Shadow Church plays the role of spies normally, it can still collect some precious information, especially in places like ruins that are not taken seriously, a lot of confidential information is actually on the surface, as long as anyone who has a heart sees it and writes it down, the information collected will actually be surprisingly detailed.

On the other hand, Angel will use his own strength to investigate these sensitive information in the church, but it will be hindered in many ways, first of all, to avoid those opposition forces, and secondly, not to alarm others, you must know that this alone Angel is difficult to do, after all, as a saint, it is simply impossible to not attract attention.

Fortunately, there are some people who help her, such as Daddy McCarthy, and those conservative forces in the church headquarters, who are the biggest help Angel has been able to successfully find clues and keep track down here.

"Well, I can imagine that." Chen Yin nodded, "It looks like we're going up again." Don't know what spectacular scenery awaits us next? ”

"It's supposed to be a rock." Angel gently patted the trouser leg that had just been soiled, "The four basic elements of earth, water, wind and fire have already seen 2 or two, and it is not difficult to guess next." ”

"Why not the wind?" Chen Yin asked, with a twitch of his head.

Angel shook his head with a smile and did not answer Chen Yin's question. Instead, Aunt Ji Ya smiled and said, "Your Excellency, let's go up from here, do you think we hit the earth element first?" Or do you encounter the air element first? ”

Chen Yin clicked his lips, looking a little embarrassed...... Sure enough, I still have a head cramp?

"Almost." Lancelot said.

He didn't participate in the previous topic, but kept staring at the fire elemental lord in the magma lake. In the previous gray pool, the power of the water element was consumed very quickly, and Chen Yin and the others had just gone down the passage and the water element had exhausted its energy.

And now the situation of this Fire Elemental Lord is not much better, he still has the strength to struggle a few times just now, and now he is lying there motionless like a salted fish. Apparently this is also a sign that the energy in its body is about to be drained.

"Well, stop talking, let's go, it'll be closed in a while." Chen Yin hurriedly grabbed a step and went down, quickly skipping the topic of the earth element or the wind element.

Next, everyone didn't bother with Chen Yin's little offense, and hurriedly passed by the huge fire elemental lord, came to the mountain wall and drilled into the upward passage.

"Well, this time it's about climbing stairs." Chen Yin looked at the steep staircase and was a little worried, his knees were already weak when he just came down the stairs, if he climbed up from here to the same height as before, then he would vomit blood.

"We can rest here for a while now, and wait for that door to close before we move on." Lancelot suggested.

"Well, okay, I'm in favor!" Chen Yin sat on the steps, took out the dried meat from his pocket and nibbled on it.

"Okay, let's take a break and don't get discovered by the Shadow Church." Angel thought about it and nodded.

And the people rested at this entrance.

Ten minutes later, the bright red flames on the body of the Fire Elemental Lord who had been absorbed by the vortex had become extremely dim, and when the last moment came, its body flickered slightly, and then suddenly disappeared.

As the Fire Elemental Lord was sucked dry, the whirlpool in the lava lake gradually calmed down, and with a "rolling" sound, a boulder slowly descended from above, cutting off Chen Yin's back path.

"Alright, it's time to go." Chen Yin was the first to stand up and took the first step.

Here, it is exactly the same as the passage that Chen Yin and the others came down before, the same stone walls, the same steps, and even the soft white light above their heads, all of which are lit wherever they go, exactly the same as before.

With such a huge ruin, I really don't know how much manpower and material resources were required to build it at that time.

"Prehistoric Civilizations...... There must be a well-developed society, right? Chen Yin suddenly sighed, "Holy Maiden, in addition to the golden relics, I wonder if you have found any other prehistoric relics?" Like the Necropolis? City? ”

"Nope." Angel shook his head.

"None? What about clay pots? Metalware? Weapons? Or is it simply the product of any civilization like stone? Chen Yin asked.

"No, nothing." Angel replied in the affirmative.

"Wouldn't it? With such a high level of technology, it is possible to build such a magnificent spectacle...... Nothing left but that? It shouldn't be! How can it take hundreds of thousands of people decades to build such a large-scale complex! How is it possible that there is no trace of life left at all? ”

You must know that Chen Yin is a graduate student in archaeology and a disciple of Professor Joshua, and this basic manpower estimation cannot be wrong.

Hundreds of thousands of people, decades of labor, and they don't even use a clay pot? Not even a stone sickle for cultivating the land? How is this possible!?

"There is nothing left of prehistoric civilizations except these huge ruins." Angel's face also had a hint of doubt, "I thought it was strange when I checked the information before, but then I saw the Sage's speculation, although I respect him very much, I can't believe his speculation all the time......"

"What did he say?"

He said......" Angel hesitated, turned to look at Chen Yin, "He said that prehistoric civilization is likely to be a passerby......"

“…… In other words, similar to you, after coming here to colonize, you found out that it was wrong, and then left again......" Chen Yin muttered to himself, but soon, a look of doubt appeared on his face again, "No! No, even if you are a passerby, you should leave traces of life! ”

"Well, I'm not done yet." Angel whispered, "The Sage also said that prehistoric civilizations may have few people......"

"No matter how little you can't ......"

Before Chen Yin finished speaking, Angel interrupted him: "There are probably no more than a few hundred people......

When "hundreds of people" spoke, Chen Yin stopped, and the whole person was stunned.

The others had to stop and stand on the steps waiting for him.

“…… Or even less, like 5? Angel ignored the stunned Chen Yin and finished his words by himself.

After listening to Angel's words, Chen Yin came back to his senses.

He ...... What is the evidence? ”

"I don't know, the back part was burned."

"When he said that, he must have found something." Chen Yin's eyes flashed with a spark of wisdom.

"Five people? Is it just 5 people? If you exclude the incredible part, such a small number of people is the most reasonable......" Chen Yin stood in place and muttered to himself, his eyes widening round, and the more he spoke, the more excited he became.

"Or maybe hundreds." Angel couldn't help but add.

"No, his judgment is five." Chen Yin smiled slightly, "The so-called hundreds, maybe he can't convince himself of a compromise." ”

"But ......"

"Alright, let's stop here." Chen Yin pointed to it, "Let's hurry up, I can't wait to see if there will be a big vortex of the earth element...... Haha, let's go. ”

As he spoke, Chen Yin took a few steps to the front and climbed up with great interest.

"What did he think?" Angel is still struggling with this question.

"Who knows, it's hard for us to keep up with your thoughts." Lancelot reassured.

Unfortunately, his comfort had the opposite effect.

"Humph!" Angel glanced at Lancelot and chased after Chen Yin angrily.

"Did I say something wrong?" Lancelot looked innocent.

"Her Highness is also a competitive person, and she must not be happy if you say that." Aunt Jiya smiled and patted Lancelot's shoulder: "For example, if you replace 'we' with 'me', His Royal Highness Angel won't be so angry." ”

“…… That's right. Lancelot opened his mouth, as if he had a lot to say, but finally sighed in dismay.

Aunt Gia looked at Lancelot with a smile and pulled Uncle Tim's shirt on the placket, and without saying anything, she turned around and continued to climb the steps.

……

Thinking about it all the way, after having the experience of the last time, Chen Yin seemed a lot more patient this time. However, after all, going up the stairs was much more tiring than going down the stairs, and after a few rests in the middle, after about an hour or so, everyone finally saw the light at the exit.

"Whew...... It's finally here. After Chen Yin saw the light, his legs, which had been holding hard, suddenly felt soft, and he hurriedly sat on the stairs to rest for a while.

The others slowly followed, and they also began to rest around Chen Yin.

"I'll do it this time." Lancelot pulled out a shield guard and put a holy shield on him, and Angel added the holy word technique to him: tenacity.

The shield guards, all of whom had been added, held their shields under Lancelot's control, and cautiously approached the exit.

As the light in front of us grew louder, so did the howling wind.

Finally, when the shield guard walked out of the exit......

"Bang!"

With a soft sound, the pale yellow god loneliness was suddenly broken, and then the shield guard snorted, and the whole person flew upside down into the passage!!

"I knew someone was coming after me." A shadowy voice came in.

Chen Yin frowned.

This voice is not unfamiliar to him.
