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

The entrance of the ruins is not far from the dwarven village, about 500 meters out of the village into the mountain, the entrance is a circular stone gate embedded in the soil slope, the stone gate is divided into two petals, the gap in the middle is not very tight, about half a finger wide, you can feel the flow of wind in front. According to the dwarven chief, the evil spirit came out of this crack in the stone.

However, the dwarves had tried many methods to open the stone door, and according to their measurements, the stone door was more than a meter thick, and the texture was so hard that even if it was beaten with a steel chisel for half a day, only a small amount of dust could be removed.

However, this time Adan brought the correct way to start the stone gate, as long as you find four seals to open the door, and at the same time use the fighting spirit of the royal inheritance of the Black Dragon Empire as an introduction, you can open the entrance to the ruins.

However, in the past three days, they have only found three of the seals, and the fourth is nowhere to be found.

"I searched all over the front and back of the mountain, but I still didn't find the fourth one. "It's a pity that the drawings recording the location of the seals were lost a few years ago. ”

"Look again, expand the scope a little more. Adan frowned, fiddling 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 have just cleared them with the help of the dwarves. As long as the fourth seal can be found today, it will not be a waste of time. ”

At this time, Ji Yijun and Chen Hansheng also walked back, Ji Yijun sat on the ground, and lamented: "Sister Luo Ling, I searched for another two hours today, but the seal was not found, and the clothes were broken by branches in several places. ”

"Alright, let's take a break and continue. Now in terms of physical fitness, we are not ordinary people, how can we be so tired?" Chen Hansheng slapped him in the back.

"I'm tired. Ji Yijun said, "You say this ancient, there is no law to make a seal, one position in the east and one position in the west, it looks like a child graffiti." ”

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

"It's hard to say, but it's hard for us to judge. There's no vantage point nearby, unless you climb up to it. Ji Yijun pointed to the top of the back mountain, "Even so, the vision you can see is not complete." Unless you fly to the sky to see. But in this winter, you won't freeze to death when you fly up. ”

"I have a better way. Luo Ling took out a space bag, fumbled in it for a while, and actually took out a drone.

"Sister Luo Ling, you still have such a thing!" Ji Yijun looked envious, leaned up to touch the east and west, this product of the industrial age awakened his memories of the original world, and he said with a nostalgic look on his face, "Good thing! It makes me miss home again, I have two of these things in my house." ”

On the side, Adan and the dwarven village chief also came over to take a closer look at this treasure, the drone is the size of a round shield, and the gray geometric fuselage and black propeller look extremely delicate and mysterious.

"This creation is so beautiful. The Dwarven Village Chief said, "We haven't seen anything so beautiful in the Black Dragon Empire's alchemy workshops and golem workshops before. ”

"What is this thing?" Adam asked curiously.

"A magic prop. Ji Yijun's words just now reminded me that maybe I could use it to find the last seal. Luo Ling continued to take out a small box with grooves, which was connected to the charger of the drone's battery. Luo Ling took out another piece of electric spar and put it in the groove. The charging indicator on the charger lights up immediately.

"That's slippery enough, who made such a thing? The current generated by the hedron can directly charge the electrical appliances? So what else do we do with electricity rationing. Ji Yijun squatted next to the drone, looking at the charger carefully, the workmanship was a little rough, but the formation and spar on it made this gadget feel like a magic prop.

"It's not that simple, the current emitted by the hedron is a pulse current, the device can't use it, and they have to be turned into direct current. This small device has filtering and voltage transformation functions, and components such as capacitors cannot be produced by the industrial group, so they can only dismantle the east wall and make up the west wall, and there is no way to achieve mass production. After charging for a while, Luo Ling took out the remote control, took out a tablet for image transmission, and after a few controls, the drone took off.

"There's no GPS here, Sister Luo Ling, do you use the attitude mode? Do you want me to try it, I can fly manually." ”

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

Ji Yijun's eyes followed the drone flying higher and higher, operating the remote control in his hand with great interest, and said in his mouth: "Hey, anyway, this allows me to see the dawn, we are there, to put it bluntly, it is an electrical civilization, with electricity, there is everything." When will the computers in my dorm be able to see the light of day? My game is still waiting for me to do another round!"

Chen Hansheng saw that Adan and the village chief were pricking up their ears and listening, and gently kicked him and said, "Don't talk nonsense, focus on attention." ”

Adan and the village chief were all drawn to the buzzing flying thing. Adan saw a lot of novelties at school, and although he was very surprised, he remained calm, but the dwarven village chief was different, scratching his ears and cheeks below, and couldn't suppress his curiosity.

The drone flew high and took a top-down photo. Luo Ling marked the location of the seals on the photo. After observing for a while, he asked Adan "Does the Black Dragon Empire have any particularly important patterns?"

"The coat of arms of the royal family is a golden-eyed black dragon. The coat of arms of the Queens is a pure white feathered serpent, the emblem of the Royal Golemist is a cogwheel iron fist, and the battle flag of the Royal Knights is a black-scaled dragon claw......" Adan recalled one by one, "Do you think that the seal can form a certain pattern?"

"I only know after comparing it. Luo Ling said.

Fortunately, there are always some items in Adan's storage ring with these emblems, Luo Ling compared them one by one, and when she saw the Golemist emblem, her eyes lit up: "Look, is the position of the three small gears around this fist very similar to the seal found?" and the location of the entrance is right here in the heart of the fist." In this way, the fourth seal should be in this position. ”

"Sure enough, this is a Golemist's secret base. 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 where the golem was made was near the imperial capital, but the place where the golem was activated and the golem was given wisdom was unknown. Adan said.

"Aren't you descendants of royalty? Ji Yijun asked.

"At that time, the emperor's army was defeated outside the imperial capital, and the emperor was nowhere to be found. My ancestor was just a young prince. The information received about the lineage is not exhaustive. ”

"Alright, let's see where the final seal is. Luo Ling compared the direction of the last gear and drew a red circle with her finger on the photo, but the circle was in the center of the valley river.

"No wonder I couldn't find it after tossing for a long time. It's a tricky place to choose, but the weather is good enough for you. Ji Yijun looked at Adan and smiled gloatingly.
