red tomb

The three of them approached the entrance again.

Taotie's mouth was already wide open, and the gap between the four fangs was enough for them to bend over to pass through.White light is also coming out of this hole, quiet and soft.

This match was really weird, and the three of them looked at each other in blank dismay.It seems to be very safe; but if it is really safe, you wouldn't shoot three iron birds at the beginning, right?They are still hovering above Jin Sheng's head!

"Enter?" Jiang Siqi asked in a low voice, nodding towards the entrance of the cave.

"Come in, I'll come first." Su You replied, and then got in short.The hole was not long, and he quickly climbed out from the pointed object at the other end, stepping on the solid ground.

There is still a whole corridor inside.Probably different from before, the limestone wall has turned into a black iron wall, and the carving on it has also changed from gluttony to a bird with three long tails.And those rays of light come from the branch candlesticks between the iron walls; the neatly lit white candles are burning quietly.

"Qingyao..." Su You murmured, and looked back at the place where he climbed out - the two ends of the hole were carved differently, with Taotie on the other side and Qingyao here; That pointed long thing is its iron beak.

"This seems to be a two-way mechanism..." Jiang Siqi was the second to pass through the hole, and was stunned by what he saw. "I mean, the different designs on the two sides can't be good-looking and functional, right?"

"It doesn't matter whether he looks good or not, it's true to come and give him a hand!" Jin Sheng's muffled voice came from the entrance of the cave.

The two looked back, only to find a big mountaineering bag moving towards the exit - Jin Sheng was pushing it behind. "Hurry up and take it away... what the hell!" His voice suddenly rose, "Can't you get out of the way of labor and management at this time!"

Su You was afraid that Jin Sheng would be pecked again, so he hurried to help.And when they finally stood side by side, all three felt that they had a long way to go—

"It was an inverted cone before, but now it's a cone?" Jin Sheng looked left and right, feeling that the prospect was not good. "It's getting harder and harder to walk!"

"I just don't know how deep it is." Su You thought. "Didn't we bump into rocks under the sand when we climbed this dune? Maybe it's the underground part of this city."

"... Isn't that still very early?" Jiang Siqi also recalled. "We've been going in circles, so the actual vertical height may have dropped a little bit!"

This is true.A square cone, going up and around the slope is naturally much slower than climbing directly from the slope.

"Calculating the altitude, we can know when we arrived at that place." Su You said.Seeing Jin Sheng's skeptical gaze, he could only add one more sentence: "...if the reading on the barometer is correct."

So stop in place.After a hasty lunch, the three began to budget for their upcoming journey.It turned out that, according to normal scientific laws, they had just reached a tenth of the height of the entire dune.If the bottom is a square cone, you won't be able to reach the bottom for ten days.

"...If things go on like this, when will we get there?" Jin Sheng lamented.He was in a rather bad mood now, for the three iron birds were still hovering above his head, making a slight, metallic humming sound.

Su You patted his old friend on the shoulder reassuringly. "The underground part of this city should not reach the bottom of the sand dunes. It would be too big, and the project volume cannot be calculated."

"If this city is really that big and it was built in the former Qin Dynasty or the former Jin Dynasty, it should exist in the history books." Jiang Siqi added, "But no, not at all. This should explain from the side that this is not a big project " He paused, then met Jin Sheng's gaze and said, "Of course, the premise is that this city was built by people."

Jin Sheng was a little discouraged.Which sand dune city built by normal people would pop up out of thin air in the forest?But he didn't say it because he knew everyone understood and there was no need to demoralize.

"Okay, let's be realistic." Su You spread his hands, "What is certain is that the depth of the dungeon can definitely reach the location of the boulder we encountered outside yesterday. And we will probably arrive at that place at noon or afternoon tomorrow."

"If you're lucky, it might be the end." Jin Sheng made a conclusion.Actually, on a more optimistic note, it's not impossible; if the dungeon was even deeper, quicksand wouldn't be possible, right?

After a short rest, the three continued to move forward.Because of the iron bird on top of Jin Sheng's head, Su You moved to the front and Jiang Siqi moved to the back.Jin Sheng had some complaints about this state of being trapped and protected, but the minority obeyed the majority, so he had to be honest.

Although Taotie was replaced by Qingyao, the Sifang Corridor has not changed.The original blindfold at the corner disappeared, and the lights on both sides were bright, which saved Su You a lot of energy.The light of the candlelight is projected on the birds fluttering their wings, and the shadows are intertwined, making them look more solemn and solemn.

"The candle is moving..." Jiang Siqi was the first to discover the New World, "Is there a wind under the ground?"

"Of course there is wind," Jin Sheng snorted, "otherwise, how do you think we can get to this point safely?" If there is no air circulation, people would have been suffocated to death, okay?

"But you can't see the vent," Jiang Siqi said.In view of Jin Sheng's current unlucky situation, the young master has a lot of adults, so he doesn't care about it like Jin Sheng!

"Probably set up in a relatively hidden place." Su You guessed.They have thoroughly inspected the iron wall, and there is no hole in it; let alone a mechanism, there is not even a small hole.

"Hmm..." Jiang Siqi pondered. "You said that the candle suddenly lit itself, is it because the gate was suddenly opened?"

"Probably, but I don't think it's because of scientific reasons—such as the influx of a large amount of fresh air, which provides the necessary oxygen for combustion." Jin Sheng replied angrily, but this was not aimed at Jiang Siqi, but More inclined to vent anger.

Either oxygen, or some force they don't understand, like hell?

Su You felt that this was really not a good guessing direction, and hurriedly withdrew his thoughts. "Never mind, it's always a good thing to be bright. And compared to that, I care more about whether there is something underneath."

This is indeed a very important question.No matter how many difficulties they have experienced before, not reaching the final goal is a failure.And their ultimate goal on the surface is to take a cup of Kunlun cup and put it back in the Qin Temple in Lishan, Paiyun Mountain.

As for the thoughts in everyone else's mind... They are different, so let's put it aside for the time being.

While they were talking, another corner was turned.Just as Su You was about to take a step, she froze, and stopped abruptly.

"What's wrong?" Jin Sheng asked quickly without hesitation.When he caught up with Su You by two steps, he found that there was still a long corridor ahead; but the difference was that the iron walls on both sides of the long corridor became smooth, replaced by a big bird hovering in mid-air.

Jiang Siqi also walked forward quickly, and was immediately stunned when he saw the bird. "Another one...seems to be exactly the same as the three on top of your head..."

"Are you kidding, is it bigger than the one on top of my head?" Jin Sheng quickly retorted, but his palms were weak - a small bird is enough to kill him; if a big bird gave him a claw, would he still be alive?

Just as they saw the bird, the bird saw them too.The direct expression is that it was hovering slowly up and down, circling in circles casually; but when it folded its head, it swooped over with lightning speed, causing the three of them to fall back in surprise.

They were too close together to turn back, and this happened in a flash, so that one fell to the ground one by one.And before their buttocks touched the ground, the big bird had already flown in front of them, its sharp iron beak glowing coldly——

"Help!" Jiang Siqi exclaimed.

Su You was the first to bear the brunt, and almost shouted out.But he immediately came back to his senses, at this time he should directly take self-defense - he raised his hand to block, trying to grab the thin and sharp long wings - but the wings tilted upward, hiding Passed over, flapped its wings again——

Its head automatically turned to the position of the tail, and the tail slid to the head end; the wings turned around in the process, and flew away without turning around.Three long iron tails brushed over Su You's cheeks, chilling.The little bird that was hovering above Jin Sheng's head also followed, flying high and low, a bit like a family.

As early as when the big bird's wings were turning, Su Yu was stunned.After the iron bird completed the difficult movement of head-to-tail rotation in front of him, he couldn't say a word——

This is impossible!How did you do it?

"...This is unscientific..." Jin Sheng, who was sitting under him, also forgot his situation, and asked dully, "Where is its power source?"

Jiang Siqi saw a little bit, but he felt that his bones were about to fall apart. "...can you guys get up and discuss this?"

5 minute later.

The three squatted at the corner, all six eyes fixed on the four birds in the sky.The bird now flies on its own, gracefully and smoothly.If it weren't for seeing the inversion process with your own eyes, it would be more real than a real bird.

"I really want to get one to take a look inside." Without the annoying bird, Jin Sheng began to itch, "If I knew it, I would have taken it apart!"

Jiang Siqi gave him a blank look. "Is that the point? I think the point is, why is the Taotie in the front and the Qingyao in the back? The former Qin and the former Jin were rivals, don't tell me they can build a city together!"

"I don't know about this, but this city must have been built together." Su You confirmed. "The totems are different, but the upper and lower designs are obviously integrated."

Jin Sheng nodded. "Then speaking of it this way, it might be half and half at the bottom? It would be better to have Kunlun cups from the former Qin Dynasty, and treasures from the former Jin Dynasty..."

"Good idea." Jiang Siqi poured cold water on him without hesitation.

Jin Sheng was not convinced. "If you can't take it, it's good to have an eye addiction!"

Su You didn't participate in the boring topic of their bickering, and just stared at the iron bird in the sky.The former Qin and the former Jin were mortal enemies, but Qingyao and Taotie appeared in the same city. What is the reason?
