The two of them then continued on their way.
The further back, the shorter the passage becomes, and both Zhang Dao and Lan Ke'er have to bend down to move forward.
And the further you go, the slope of the passage becomes larger and larger. The stone walls on both sides of the passage are covered with frost, as if they are heading underground to the bottom of Tianchi.
After walking for almost half an hour, we finally came to a stone gate.
"This..." Lan Keer stared blankly at the stone door in front of her.
She didn't expect that there would be a tunnel dug so deep beside the Tianchi.
It is hard to imagine how much manpower and material resources it would have required to build such a passage under ancient conditions!
Zhang Dao didn't care about this, he walked to the stone door and started groping.
Lan Keer asked curiously: "Brother Zhang Dao, what are you doing?"
"Look for the stone gate mechanism here. Since the other party has built such a long passage in the land of dragon veins, it naturally cannot be someone's cemetery."
"I guess it was probably built to house something, so the thing I want is probably still here!"
"Really?" Lan Keer's eyes lit up, and she immediately became energetic when she heard that this trip might be worthwhile.
Although she didn't know what Zhang Dao was looking for, as long as Zhang Dao found it, he would be very happy, and then she would be very happy too.
So Lan Keer also stepped forward excitedly and helped Zhang Dao search near the stone gate with the help of the light of his mobile phone.
The two of them searched for a while. Zhang Dao stood in front of the stone door and frowned in deep thought.
Lan Ke'er was also slightly out of breath and took off the furry hat on her head and held it in her hand.
Lan Keer wanted to go to Zhang Dao, but she took one step, twisted her feet, and fell to the side.
"Ouch!" Lan Ke'er exclaimed and hurriedly reached out to hold the wall.
Zhang Dao turned around when he heard the sound, but saw Lan Keer falling to the ground.
Turning around to help her, she walked to Lan Ke'er's side, but suddenly she heard a 'click, click, click' sound.
Zhang Dao was greatly moved and hurriedly pulled Lan Keer back a few steps to protect her behind him. At the same time, he moved invisible protective energy in front of him to prevent some mechanism from suddenly activating and hurting people.
Lan Ke'er, who was standing behind Zhang Dao, heard the "click-click" sound echoing in the passage, grabbed Zhang Dao's military coat and asked tremblingly: "Brother Zhang Dao, what is this?"
"It's nothing, it's just that you were lucky enough to activate the Shimen mechanism!" Zhang Dao said with a smile, turning his head slightly, but his eyes were fixed on the Shimen in front of him.
"Me? Am I so powerful? Hehe!" Lan Keer giggled, slightly sticking his head out from behind Zhang Dao and looking at Shimen in front of him.
As the sound of 'click click' echoed, suddenly a 'rumbling' sound came, as if coming from underground.
Lan Keer looked frightened and clutched Zhang Dao's military coat tightly, but because Zhang Dao was standing in front of her, she didn't show it.
After a while, a "creak" sound was heard.
Under the gazes of Zhang Dao and Lan Ke'er, the stone door slowly slid aside.
Zhang Dao's eyes tightened, the stone door slowly opened, and a burst of white mist overflowed.
Zhang Dao's expression tightened, and he hurriedly waved a strong wind to disperse the overflowing white mist.
Watching the white mist drifting to both sides of the passage, it turned into ice crystals visible to the naked eye.
Zhang Dao breathed a sigh of relief.
Lan Keer was slightly worried and asked: "Brother Zhang Dao, what is this? Is it poisonous?"
Zhang Dao smiled and said: "It's just some water vapor, but it's also poisonous? Do you really want to treat it as poison for free?"
"But I've read that it's written like that in some tomb-robbing novels?" Lan Ke'er tilted her head and asked in confusion.
Zhang Dao explained: "These underground buildings are underground after all. Even if there is any poison that can be made for free, after so many years, it has long since melted into the underground soil."
"Unless a huge amount of mercury is poured into it like the Mausoleum of Qin Shihuang, in that case, there will still be huge dangers even after thousands of years have passed."
"Oh, so that's it!" Lan Ke'er nodded in realization and asked, "Then shall we go in now?"
Zhang Dao shook his head slightly, "Let's wait for a while. Let the air in the stone door interact with the passage for a while to ensure that there is sufficient oxygen before we go in."
"Well, brother Zhang Dao knows so much!" Lan Keer praised.
Imperial Capital, Investigation Bureau.
Suddenly a piercing alarm sounded throughout the night sky.
The deputy director on duty, Lan Jianjun, ripped off the quilt covering his body and rushed to the monitoring room.
As soon as he entered the door, he hurriedly asked: "What happened? Why did the device alarm again?"
The monitoring personnel on duty hurriedly said: "Report, just now, the device worn by the giant salamander suddenly lost contact."
"Baby fish?" Lan Jianjun frowned when he heard this. Although he felt uneasy in his heart, he couldn't help but feel slightly relieved when he thought of her acting together with Zhang Dao and Zhang Dao's terrifying skills.
"Where did the signal finally disappear?"
"The report is in Changbai Mountain!"
Changbai Mountain? Lan Jianjun frowned slightly.
Did he know that Zhang Dao took Salamander to Changbai Mountain, or that Salamander asked him to book the flight.
Lan Jianjun nodded slightly, thought for a while, and said to the staff: "Clear the alarm first and make a good log record. There is no need to report to superiors for the time being!"
"Yes!" the staff responded.
Lan Jianjun turned to go out, but turned back and warned: "Always pay attention. If the signal of the giant salamander fluctuates again, report it to me immediately!"
"yes!"
In front of the stone gate at the end of Tianchi Tunnel,
After waiting for almost ten minutes, Zhang Dao struck a match and threw it into the stone door.
Finding that the match could still burn, he turned around and winked at Lan Keer, then stepped forward.
Lan Keer nodded slightly and followed Zhang Dao lightly.
After entering the stone gate, Zhang Dao was not in a hurry to enter. Instead, he stood at the door and carefully looked around the environment inside the door with a flashlight.
Opposite the door is a screen wall made of huge stone, with stone carvings of wealthy families carved on the screen wall.
Zhang Dao carefully observed the screen wall and the rock walls on both sides of the door and the situation on the top. After finding nothing out of the ordinary, he stepped out.
Keep your feet firmly on the ground, there seems to be no traps.
Zhang Dao pulled Lan Ke'er and walked forward slowly.
The reason why he held Lan Ke'er was, firstly, to prevent her from falling behind, and secondly, if there was any emergency, he could protect Lan Keer in time.
The two of them walked cautiously towards the Zhaobi, while Lan Keer followed Zhang Dao without even daring to breathe.
Before passing by the screen wall, Zhang Dao checked it carefully and found that the screen wall was made of large stones. There was nothing special about it, so he didn't pay too much attention to it.
When the two of them walked past the screen wall, they suddenly became enlightened.
