Kill one person in ten steps, and do not stay for a thousand miles.

After the matter, I left with my clothes and hid my name.

——"Xia Ke Xing" Li Bai

...

After roughly walking the underground fortress for a while, Sun Dashanren said, "The tunnel buried so deeply does not feel any suffocating. There is no way to know where the vent is located. This alone shows the skills of the craftsman of Qingxuan.

From this point of view, the secret passages of Princess Taiping’s mansion are divided into two layers: upper and lower levels. The culvert is divided into the middle, making it more difficult to find the secret passages on the lower levels.

As the saying goes, a leaf obstructs the eyes and cannot see Mount Tai.

I guess that Princess Taiping should have placed a lot of money in the first floor secret room, with the purpose of confusing the treasure hunter. No matter whether this person is an enemy or an insider, it is difficult to discover the secrets of the lower floor secret room.

When Princess Taiping failed in the coup, Xuanzong sent people to search the house, even if he could find the upper secret room, it would definitely take a lot of effort.

The search officers and soldiers finally entered the secret room and found so much wealth and were confused by the shining gold and jewelry. They must be very happy. It is hard to imagine that there is a layer of secret passage under the dark river.

Usually, the chief general of the army will focus on how to restrain the soldiers, avoid officers and soldiers from robbing goods, and how to transport these jewelry out of the secret room without any accident. It is difficult to concentrate on continuing to explore other secret rooms.

The head of Qingxuan has a clear understanding of human nature and is able to consider human greed, laziness and other emotions at the beginning of the design of the secret passage. I have to say that it is unique and meticulous."

Sun Dashanren also saw countless people in the tombs of the imperial palaces. Seeing this, he couldn't help but admire the leader Qingxuan.

In the Tiankeng near the "Tianfu Guanyi", Bai Fu heard Wu Zhao talk about this past: After Princess Taiping's party was executed, the master single-handedly challenged the Emperor of Tang without any disadvantage.

Although I admire the courage of my master, I also thought of a question: Although my master is very skilled in martial arts, he is hard to beat four hands with two fists, not to mention that there are top masters like Gao Lishi around Xuanzong to protect him.

Wu Zhao said that his master planned assassination many times, and he accidentally won the deputy chariot several times, almost succeeding, making the Emperor of Tang in a mess. If it weren't for the iron cavalry on the grassland and the smoke of wolf on the border, he wouldn't know who would have killed him.

With the power and prudence of Xuanzong, the master was able to escape unscathed after many assassinations. This alone has shocked the world.

Now it seems that the master is likely to use these secret ways to eluddle gods in Chang'an City and enter and exit the realm of no one.

In addition, there are so many treasures in the underground fortress: whether it is to buy the servants around Xuanzong, learn about Xuanzong's daily life, or arrange retreat routes, and get secret protection from the gangs in the world, the master fully releases the power of money.

According to Wu Zhao, the master was defeated by Xuanzong's plan to distract himself from the incident. He was ashamed and embarrassed by Xue Zhao's affairs, which led to his disheartenedness towards Princess Taiping and his clan and left with his seal.

If time goes back and the master will do his best to assist Princess Taiping, I still don’t know what the Tang Dynasty is today.

...

Just when Bai Fu was deeply moved, Sun Dashan found dozens of iron objects similar to round tables in the secret room. The tabletop was a large iron-cast ring, and the middle was woven into a mesh with ropes such as beef tendon. Under the table were several iron-cast table legs, which were solid and solid.

Grandma Sun summoned Bai and said, "Brother Bai, what is this? Have you ever known?"

Bai Fu was stunned when he saw it and said, "This is the jumping ball bow net used by our Qingcheng to practice light skills. With the elasticity of the beef tendon on the bow net, you can freely rotate and tumbling in the air. You don't know what the purpose is to put it here?"

When Sun Dashan heard this, he became interested and stood on the net of jumping on the ball bow. His big belly and pooped body turned out to be as strong as a swallow.

Bai Fu's eyes lit up and he smiled and said, "I know what this is for." Bai Fu first moved the jumping ball bow net to the bottom of the wellhead, and then asked Tu Xingsun to move the wooden barrel and winch rack above the wellhead.

Bai Fu simply put a set of bright light armor on his body and stood on the jumping bow net. Bai Fu first jumped gently several times, and after the rhythm was free, he exerted force under his feet and rushed to the well with a "swoosh".

Sun Dashanren made the case according to law, and after trying it twice, he could easily reach the wellhead.

Sun Dashanren praised: "The leader of Qingxuan is indeed a genius, and he can come up with such a way to get out of the well."

Tu Xingsun wondered and asked, "Sitting in a wooden barrel, you can get out of the well through a winch, why do you need to design this method?"

Bai Fu replied: "If the soldiers wear the bright light armor, their weight will increase exponentially, and the wooden barrels will not hold a few people at a time.

Soldiers are very fast!

If you are well trained and use this method to get out of the well, more than a thousand soldiers can all get out of the well in half an hour and get all assembled."

...

Back in the well, Sun Dashan took out the compass to determine the location and said, "Our current location should be several feet below the lake in the back garden.

According to common sense, in addition to the wellhead, there should be an exit at the other end of the secret passage. If you keep moving forward, you will reach the back door of the mansion."

The two walked along the tunnel in the fort to the end, turned a corner, and an underground river appeared in front of them. Their location was actually a stone pier.

The shore of the pier was neatly filled with uninflated sheepskin rafts and black-sailed boats.

Sun Dashanren walked to the waterside and looked at it for a moment, and said, "According to the trend of the water flow, you can walk out of the secret passage through this waterway.

The two of them worked together to push a black-sailed boat into the water. They lit the wind lights hanging on the roof of the black-sailed boat. The two of them rowed their sloping paddles and walked along the underground river. After a stick of incense, several forks appeared in the waterway.

Sun Dashanren praised: "This waterway is like a maze. Even if someone accidentally breaks into the waterway, he will be confused by these forks and cannot enter the underwater secret passage of Princess Taiping's mansion."

The Grand Sang took out a compass and a dragon-seeking ruler, and constantly adjusted the direction of the ship.

After another half an hour, a light appeared at the end of the tunnel. Needless to say, the exit is about to come.

Bai Fu was very excited and accelerated his paddling speed. The black-sailed boat soon arrived at the entrance of the tunnel, and a locked iron fence appeared in front of him.

The Grand Shanren Sun took out a copper wire and tweaked it in the keyhole, and the copper lock opened in response.

When I pushed open the iron fence, I saw a reed marsh in front of me. The reeds were more than one person tall, with weeds growing, and the top of my head looked like the bottom of a stone arch bridge.

Sun Dashan nodded and said, "The exit is located at the bottom of the bridge. If there are not many ships passing through the bridge hole, it is not easy to find it."

Before he finished speaking, a huge roar was heard, and a waterfall poured down from above the arch bridge, and the bridge hole instantly turned into a thick water curtain.

After a moment, the water curtain dissipated and a rainbow appeared in the sky outside the bridge.

The two of them rowed the black-sailed boat out of the bridge hole, turned around and looked again, and then they suddenly realized.

It turns out that this bridge is not an arch bridge for people to pass through, but an arched irrigation canal made of bricks and stones. There is a huge water truck above the canal, and every once in a while, the water on the roller will be poured down. Looking from below the bricks and stone canal, it looks like a waterfall falling from the sky.

Sun Dashanren praised: "The combination of this water truck and the canal is flawless, making the exit of the secret passage more secret.

Ordinary people would not row the boat into the underwater canal. Even if some curious people row in and find the iron fence hole in the weeds, they would only think that this is a culvert for sewage discharge or flood discharge in Chang'an City."

Bai Fu nodded and said, "The water curtains on both sides of the stone canal are also a natural trick. The water curtains fall and dissipate, and the ship disappears.

If someone sees it, the boat disappears after entering the bridge hole. He will take it for granted that the boat is passing through the bridge hole and sailing away, and will not think that there is another cave here."

...

The two looked around and saw a wide terrain in front of them, with winding and continuous rivers, red and green willows on both sides, and beautiful scenery. This place should be the intersection of Longshou East Canal and the Wu River at the northeast corner of Chang'an City.

Sun Dashanren was once again amazed and said, "With this waterway, Princess Taiping can secretly transport more than a thousand soldiers and billions of wealth into Chang'an at any time, launch a coup, and achieve her great cause.

The leader of Qingxuan is a master of his generation. What a pity, it’s a pity..."
