Ye Ran visually inspected it, the entire cave was about the size of a football field, and several palm-sized fluorescent stones were inlaid on the surrounding cave walls, emitting a faint light.

Because the light was too dim, he didn't find the mechanical door that Zhao Xiaoou said, so he asked, "Did you enter this cave just now?" Why didn't I see a mechanical door here?"

Zhao Xiaoou looked around, most of the places in the cave were pitch black, and she couldn't see anything clearly, she couldn't help frowning, "It's too dark here, there is nothing to identify, I don't know, let's look for it first, anyway, with my luck, I can find it even with my eyes closed." ”

After finishing speaking, he took the lead and walked into the darkness, Ye Ran immediately followed when he saw this, and the Heavenly Dao and Yiyang Sword Immortal followed.

Sure enough, Zhao Xiaoou did not disappoint everyone. It didn't take long for a mechanical gate made of various unknown metal materials to be more than ten meters high and appear in front of them.

The gate stood in the middle of the cave without any support, and the sides of the gate were empty except for a few chains thicker than an arm.

The Heavenly Daoist and the Yiyang Sword Immortal walked up curiously, touched it over there, kicked it twice, and studied it for a while without seeing what was so special about it.

Ye Ran stood aside and carefully observed the gate, and vaguely saw that there seemed to be some strange graphics painted on it.

He took out the flashlight from the Na Ling ring, stepped on the flying sword and slowly ascended it, only to find that those strange shapes formed a series of vivid murals, and these murals seemed to tell an ancient story.

He immediately told everyone about this discovery, and when the Heavenly Dao and Yiyang Sword Immortal heard this, they immediately became interested, and they jumped up and flew up.

However, because the two of them didn't dare to get too close to Ye Ran, they only dared to watch from a distance, and the light was insufficient, so they couldn't see the content on the mural at all.

Ye Ran saw that they were actually separated from him by nearly ten meters, and couldn't help but pout helplessly, "I'm not a flood beast, why are you so afraid." ”

The Heavenly Daoist swallowed his saliva and said with a frightened expression: "Xiao Yezi Daoist is too modest, although you are not a flood beast, but you are a biochemical weapon that is more terrifying than a flood beast!"

The whole person is extremely poisonous, for the sake of life, it is better for us to stay away from you. ”

Yiyang Sword Immortal nodded again and again, expressing his approval, but in this matter, he stood on the same line as the Heavenly Daoist.

Ye Ran: "......"

At this moment, Zhao Xiaoou, who was still standing below, looked up at the three of them, and suddenly said, "Do you want to see the content of the mural? ”

She raised the white ring on her hand and said to Ye Ran, "Little Ye Daoyou, give me that ring of yours." ”

Hearing this, Ye Ran controlled the flying sword to land slowly, and handed her the black ring.

After Zhao Xiaoou received the ring, he easily found the two recesses above the mechanical door and put the ring on it.

"Click, click!"

The sound of gear transmission came, and Ye Ran saw that a beam of energy with a blue arc shot out of each of the two rings, and the beam continued to swim along the lines that were engraved on the door like a computer chip, gradually lighting up the entire mechanical door.

Looking at the mechanical gate wrapped in an arc all over his body, Ye Ran couldn't help but be amazed, he had only seen this kind of futuristic sci-fi scene in blockbuster movies, but he didn't expect to be lucky enough to witness it today.

At this time, the cave was completely illuminated by the light emitted by the mechanical gate, and Ye Ran flew up again and began to observe the murals.

The first mural depicts a spaceship in the shape of a flying saucer that landed on Earth by chance.

The primitive tribes of Earth mistook the aliens who came down from the spaceship for gods and worshipped them.

Ye Ran was shocked, if the mural depicted was true, it meant that aliens really existed and had visited the earth a long time ago!

He continued to look down.

The next depiction is that the aliens, after learning that this is a backward planet, relied on advanced technology, provoked a war, and quickly controlled all the primitive tribes at that time.

Just when the aliens thought they had taken full control of the planet, the sky suddenly shattered into countless pieces like a mirror, and two giants fell from above.

The two giants are hostile, and the battle between them instantly destroyed the dynasty that the aliens had worked so hard to establish, no matter how the aliens attacked, they could not cause any damage to the two giants, and in desperation, they had to flee the earth in a spaceship.

However, before leaving, they worked hard to build a huge portal so that they could return to Earth when they became stronger......

After reading all the murals, Ye Ran was shocked in his heart, he didn't expect that there would be such a buried history.

The Heavenly Daoist pursed his dry lips and said, "At that time, the technology of the aliens was so high, who were those two giants who fell from the sky? Being besieged by so many mecha of the aliens at the same time, there was nothing at all, and it was too powerful!"

Ye Ran had some guesses of his own about the two giants, Yun Shuiyao said that the predecessor of the Void Illusion Realm was the battlefield of gods and demons, and they found the remains of aliens here, so it is very likely that those two giants are ancient gods and demons.

Otherwise, the aliens wouldn't be defenseless.

......

At the same time, in the depths of the universe, on a huge starship, a humanoid creature with an octopus face is listening to the report of his subordinates.

"Sir, just now we detected the signal from the portal on the Blue Star, and the person who took the energy ring returned the ring for some reason, do we need to take the opportunity to make a space jump and go to the Blue Star?"

Hearing this, the octopus chief pondered for a moment, and slowly shook his head, "Don't worry, with our current technology, we may not be able to deal with the ancient gods on the Blue Star, you record the coordinates of the portal first, so that even if the portal is destroyed, we can also find the Blue Star through the coordinates." ”

"Sir, are the ancient gods on the Blue Star really as powerful as the ancestors say, our scientific and technological strength is already very strong, can't we still deal with them?"

"Well, if you've seen the footage that has been handed down, you wouldn't say that.

The power of the ancient gods is definitely beyond your imagination. In short, we must not underestimate the enemy, so you go down and pick a capable subordinate to come out and send it to Blue Star to find out the situation there. ”
