"Alright, let's go as soon as possible." looked at the two women, Chen Fan said.

Then the three of them entered the passage and walked into the depths.

As it progresses, the passage becomes a natural passage from the first artificial excavation.

Finally, after walking for a while, the three of them entered a huge cave.

"Wow, that's a real situation." Looking at the ancient buildings built inside the cave, Momoko let out an exclamation.

"Indeed, it is inconceivable that Jacob led his people to such a gigantic and circumstantial scene centuries ago." Laura sighed.

Chen Fan glanced at the situation inside the cave and said, "This should only be the frontier of Ji Te Chen, but from one point, it can be inferred that the scale of this ancient city is very huge. ”

"Then let's hurry as soon as possible, we must reach Kit City before the Holy Trinity to obtain the Divine Source." As she spoke, Laura walked along the spiked path towards the building across the cave.

Walking on the silent cave road, Chen Fan thought about it and planned to tell the two girls about his injury, "Girls, it's up to you to go next, I was a little injured in the previous explosion, so you have to be careful if you encounter any emergency, I must heal my injuries before the final battle." ”

And the two girls, who were originally in a heavy mood because of this period of time, were shocked when they heard Chen Fan say this.

"What? You were actually injured in the explosion just now, why didn't you tell us? Laura was shocked when she heard this.

"Why don't you go back to rest above the ground? This time, I'll let Laura and I go. Peaches also looked at Chen Fan with a worried expression.

Hearing the words of the two daughters who cared about him, Chen Fan's heart suddenly warmed, but he still waved his hand and rejected the proposal of the two girls.

"The injury is not very serious, I will try not to make a move in the next battle, thinking that it will not be a big deal, but then it will only depend on you."

"Okay, don't even make a move later, just let me come with Laura." Although worried about Chen Fan's injury, Peaches still instructed obediently.

"Peaches is right, you can rest assured that you can leave it to us." Laura nodded as well.

"Then you have to be careful, I think the road will not be so easy after I come." Chen Fan looked at the two women and quipped.

"Just look at it." While talking, the three of them finally came to the building in the cave not far away.

Laura turned on the radio and started contacting Jacob, "Jacob, we're going in, is there anything to keep an eye out for?" ”

"Zizi, after we sealed the entrance a few worlds ago, no one has entered again, but it should be safe inside. At least there will be no danger until you reach the orremosphere. "The signal wasn't very good, but it was received by Jacob.

"Is this orredrosphere an observatory?" I'm very interested in this thing that sounds a little tall when it sounds like a name.,Peach.。

"Yes, it was forged by our astronomers before the undead legions flooded the ancient city. You'll have to rely on it to open the entrance to Kit City. Between the words, Jacob was full of pride in the deeds of his people.

Centuries ago, Jacob's people were far ahead of the outside world in technology.

You must know that at that time, human beings had just learned that the earth revolved around the sun, and Jacob and his scientists had already used this knowledge of the solar system to create mechanisms.

As they spoke, the three of them entered a large room along the building inside the cave.

Looking at the solar system that had been created to hang in the center of the room, Laura let out an exclamation, "Really...... It's really amazing. ”

"yes, I can't believe that they already had this kind of understanding hundreds of years ago." Looking at the solar system suspended in the room, although it is simple, it can still be seen and understood, Chen Fan agreed.

"So what are we going to do next?" Looking at the forbidden solar system peach, who didn't understand, looked at the two of them in confusion.

"En~~ I'll study it first." As she spoke, Laura observed along the edge of the solar system.

After a while, she turned to the two of them and said, "I looked, the entrance to Git City should be at the entrance of the cave above, as long as we run this solar system, the entrance should be open." ”

"So how do you get the solar system moving?" Momoko looked in the direction that Laura was pointing, and vaguely saw a hole in the upper part of the solar system.

Hearing this, Laura snapped her fingers and said, "It's easy, look at me." ”

After saying that, Laura jumped to a planet in the solar system with a leap.

Then came Laura's gymnastics time, and between her jumps and movements, she made her very fast to a high platform at the edge of the middle of the solar system.

As she pushed a trap, a bracket stuck at the edge of the solar system was retracted.

Next, she went to a high platform on the other side of the solar system and repeated her previous movements.

Finally, when both brackets were withdrawn, the solar system without the 'brakes' finally began to slowly move.

Looking at Laura, who jumped back, Momoko exclaimed, "Wow, how do you say it works?" ”

"I don't know the specifics, but the observatory is located in a geothermal valley, so I think this solar system should be powered by geothermal energy." Chen Fan groped his chin and guessed.

The two women are not sure of Chen Fan's speculation, but the truth of the facts is that Chen Fan guessed that it is inseparable.

The scientists did use the geothermal combined with the underground water system inside the valley to evaporate the water vapor, and then use the evaporated water vapor to drive the solar system.

However, this project is quite huge, and those mechanisms are hidden in the depths of the cave, so on the surface, the three of them can't see the reason for a while.

"Okay, for these things we shouldn't study for the time being, it's imperative that we enter Kit City as soon as possible." Chen Fan saw that the two women looked like they were thinking and hurriedly interrupted them, he was really afraid of arousing the interest of the two women, so he didn't care about the business and went to explore what was inside.

As soon as the two girls heard Chen Fan's reminder, they suddenly came to their senses and knew that the two of them had thought about it for a while.

At this time, as the solar system rotated, the entrance above the building was finally fully opened.

The trio climbed up the orrekiar, entering the secret entrance beneath the observatory.

After passing through the entrance, the three of them successfully entered the passage of the undead legion mentioned by Jacob, the road here is very difficult to walk, and with the fact that no one has repaired it for centuries, many places have rotted, and the slightest carelessness of people walking on it will cause it to collapse, and then fall into the abyss and fall to their deaths.

Just as the three of them were nervously sneaking, suddenly Sophia's voice came over the radio, "Laura, Chen Fan, Peach, are you there?" ”

"What's the matter, Sophia?" Laura replied.

"We have reached the mountain above the glacier, and the Holy Trinity is preparing to chisel through the glacier into Kit City, and our side intends to cause an avalanche to destroy them." Sophia's tone was full of resentment.

Come to think of it, for the invaders of the Holy Trinity, many of Sophia's clansmen have been killed by the other party, so it is reasonable that Sophia naturally hates the other party very much.

"Don't do this Sophia, if you cause an avalanche, what about the people you left behind in the valley? Do you want to watch them accompany the Trinity to the funeral? Give us a little time, we are about to enter Kit City, and we will definitely get the Holy Source before the Holy Trinity, please trust us. Laura hurried to stop Sophia's intentions.

Sophia's side fell silent after hearing Laura's words, and finally she compromised, "Okay, we'll try to buy you time, so I implore you to get the Divine Source as soon as possible." ”

Hanging up the communication, Chen Fan and the three of them accelerated their pace and walked towards the direction of the ancient city.

Soon, the three of them faintly heard the noise of someone talking in the distance.

As the three of them approached, they watched the figure walking back and forth on the cliff building.

"Who are they? Don't? Looking at these busy figures, Momoko guessed.

"Yes, these should be the undead legions." Chen Fan's answer confirmed Peach's guess.

"These people look completely indistinguishable from normal humans." Laura also observes the undead legion's every move.

"I guess the other party should still have memories or some habits of being born as a human being. Since it's called the Undead Legion, I think it should be some undead or something. For these undead legions, Chen Fan was also confused for the time being.

"No matter, let's leave quickly, I don't know if these people are humans or ghosts, let's get the Divine Source as soon as possible and leave here." As soon as she heard Chen Fan's words, Taozi suddenly shuddered, urging the two of them to leave quickly, you must know that she was still a little stunned by these gods and ghosts.

The three of them then took advantage of the terrain and began to sneak into the center of Kit City.

"What do you say they're doing? It looks like it's going to war. A hidden place, Momoko asked, looking at the undead legions running around.

"It should be that they discovered that the Holy Trinity intends to forcibly attack Kit City, and they, as the masters of the 'guard' here, naturally want to destroy these invading people." Laura speculated on the other party's actions.

However, what she said was really good, the Holy Trinity was not like the three of them, the other party relied on his own well-equipped personnel and many personnel, and adopted a strong attack mode.

Such a move would naturally be blocked by the undead legion.

"Wouldn't it be better to let them eat dogs, and we can take advantage of the chaos to get the Divine Source." Seeing the other party's busy appearance, he said happily.

Suddenly, a hand slammed on her head.

"What do you want to eat, the source of the Divine is the fundamental existence of the undead legion, do you think the other party will not arrange heavy guards? Do you think you're buying Chinese cabbage on the street? Chen Fan's angry voice came.
