On the Seven Towers

Luo Ling, Adan and the dwarf village chief were at the entrance to the ruins behind the mountain, waiting for the results of the search by others. This is already the third day of trying to open the gate to the ruins.

The entrance to the ruins is not far from the dwarf village, about 500 meters out of the village and into the mountain. The entrance is a circular stone door embedded in the soil slope. The stone door is divided into two parts. The gap in the middle is not very tight, about half a finger. It's wide, and you can feel the flow of the wind when you get close to the front. According to the dwarf village chief, the evil spirit came out of this crack in the stone.

However, the dwarves tried many methods but failed to successfully open the stone door. According to their measurements, the stone door was more than one meter thick and extremely hard. Even if they hammered it with a fine steel chisel for a long time, they could only get out a few dust particles.

But this time Adan brought the correct way to open the stone door. As long as he found four door opening seals and used the fighting spirit inherited from the royal family of the Black Dragon Empire as a primer, he could open the entrance to the ruins.

However, in the past three days, they had only found three of the seals, and the fourth one was missing.

"We have searched both the front and back of the mountain, but we still haven't found the fourth one." Knight Matthew came back to report, "It's a pity that the drawings recording the location of the seal were lost a few years ago."

"Look again and expand the scope." Adan frowned and fiddled with the hilt of his sword.

Luo Ling comforted: "The seal is always there, it's impossible not to find it. As for the other seals, we just cleaned them up with the help of the dwarves. As long as we can find the fourth seal today, it won't be a waste of time. ”

At this time, Ji Yijun and Chen Hansheng also came back. Ji Yijun sat on the ground and lamented: "Sister Luo Ling, I searched for another two hours today, but I couldn't find the seal. My clothes were scratched in many places by branches."

"Okay, let's rest for a while and continue. Now we are not ordinary people in terms of physical fitness. How can we get tired just like this?" Chen Hansheng slapped him on the back.

"I'm tired." Ji Yijun said, "You think of these ancients, there is no pattern in how to create a seal. One location in the east and one in the west. It's like a child's graffiti."

"Doodle?" Luo Ling's eyes lit up, "What you said reminded me that the position of the seal may not be a simple geometric shape. Maybe it is like a constellation, a few important points in the shape?"

"It's hard to say. Even if it is true, it is difficult for us to judge. There is no commanding height nearby, unless you climb up there." Ji Yijun pointed to the top of the back mountain, "Even so, the view is not complete. . Unless you fly to the sky to see it, it’s winter and you won’t freeze to death.”

"I have a better way." Luo Ling took out a space bag, fumbled around inside for a while, and finally took out a drone.

"Sister Luo Ling! You actually have such a thing!" Ji Yijun looked envious. He leaned over and touched here and there. This product of the industrial age awakened his memories of the original world, and he looked nostalgic. He said seductively, "What a good thing! It makes me homesick again. I have two of these things at home."

Adan and the dwarf village chief also came over to take a closer look at this treasure. The drone was the size of a round shield, with a gray geometric body and black propellers. It looked extremely delicate and mysterious.

"This creation is so beautiful." said the dwarf village chief. "We have never seen such a beautiful thing in the alchemy workshop and golem workshop of the Black Dragon Empire before."

"What is this thing?" Adan also asked curiously.

"A kind of magic prop. Ji Yijun's words reminded me just now. Maybe I can use it to find the last seal." Luo Ling continued to take out a small box with a groove, which was connected to the charger of the drone battery. Luo Ling took out another electric crystal and placed it in the groove. The charging indicator light on the charger came on immediately.

"This is pretty slippery. Who came up with such a thing? The current generated by the crystal can directly charge electrical appliances? Then what kind of power rationing system do we have?" Ji Yijun squatted next to the drone and looked at the charger carefully. The workmanship is a bit crude, but the formations and crystals on it make this gadget feel like a magic prop.

"This is not that simple. The current emitted by the crystal is pulse current, and the equipment cannot be used. It must be converted into direct current. This small device has filtering and transforming functions. Components such as capacitors cannot be produced by the industrial group. The alternative is to demolish the east wall and repair the west wall, and there is no way to achieve mass production." After charging, Luo Ling took out the remote control and a tablet for image transmission. After a few controls, the drone took off. .

"There is no GPS here. Sister Luo Ling, are you using the attitude mode? Do you want me to try it? I can fly manually."

"I can't spare you if you smash it." Luo Ling handed him the remote control, picked up the tablet, and asked Ji Yijun to adjust the flying attitude of the drone through the position captured by the camera.

Ji Yijun followed the drone flying higher and higher, operating the remote control enthusiastically in his hand, and said: "Oh, no matter what, this allows me to see the light of day. Where we are, to put it bluntly, Electric civilization, with electricity, everything is available. When will the computer in my dormitory see the light of day again? My game is still waiting for me to play again!

Chen Hansheng saw that both Adan and the village chief were listening with their ears pricked up, so he lightly kicked him and said, "Stop talking nonsense and concentrate."

Adan and the village chief were all attracted by the buzzing flying thing. Adam saw a lot of new things in school. Although he was very surprised, he remained calm. But the dwarf village chief was different. He scratched his head and couldn't suppress his curiosity.

The drone flew to a high altitude and took a bird's-eye view. Luo Ling marked the location of each seal on the photo. After observing for a while, she asked Adam, "Is there any particularly important pattern in the Black Dragon Empire?"

"Pattern? The emblem of the royal family is the golden-eyed black dragon. The emblem of the queen's family of all generations is the pure white feathered serpent, the emblem of the royal golem is the gear iron fist, and the battle flag of the Royal Knights is the black-scaled dragon claw..." Adam recalled one by one, "Do you think the seal can form a certain pattern?"

"You will know after comparing it." Luo Ling said.

Fortunately, there are always some items with these emblems in Adan's storage ring. Luo Ling compared them one by one. When she saw the emblem of the golem master, her eyes lit up: "Look, aren't the positions of the three small gears around this fist very similar to the seals we found? And the entrance is right here in the center of the fist. So the fourth seal should be here."

"Sure enough, this is a secret base of a golem master. Because it is difficult to keep secrets in the royal capital, the empire's golem research has always been carried out in several secret bases. The workshop for making golems is near the imperial capital, but the place where the golems are activated and given wisdom is unknown." Adan said.

"Aren't you descendants of the royal family? How could you not know these things?" Ji Yijun asked.

"At that time, the emperor's army was defeated outside the imperial capital, and the emperor disappeared. My ancestor was just a young prince. The information he received about the inheritance was not detailed."

"Okay, let's see where the last seal is." Luo Ling compared the position of the last gear and drew a red circle on the photo with her finger, and the circled place was in the center of the small river in the valley.

"No wonder you can't find it after tossing for a long time. The place you chose is too tricky! However, the river will be enough for you in this weather." Ji Yijun looked at A Dan and smiled gloatingly.
