I only saw that on the left and right sides of the passage, what normally looked like two ordinary yellow mud walls. But when looking at it from perspective, Xiang Dongliu found that the hidden behind the yellow mud wall were actually two super-large mechanisms.

It is as dense as an assembly line for the production of sharp arrows, and each arrow is tightly clamped in an orderly manner, pointing to the passage from afar, waiting for it to be launched in turn.

As for the trigger switch, it is placed at the bottom of the passage, and if someone accidentally steps on the trigger mechanism, the sharp arrows on the left and right sides will break through the wall with great speed, and the future will be pierced through the heart.

"Who the hell designed this? Awesome, right? ”

Xiang Dongliu muttered incredulously at the dense mechanism behind the yellow mud wall, thinking to himself that this level of complexity would definitely be a remarkable invention even in modern times.

This mechanism is purely a lever and a bow-drawn physical method. As long as someone steps on the trigger switch, it is equivalent to using the lever principle to easily pull the sharp arrow bowstring that requires a lot of force to pull, and then let the sharp arrow shoot out.

To put it bluntly, it is to draw a bow and shoot yourself, which is equivalent to suicide, but the person who committed suicide does not know.

"Fortunately, my brother has a perspective treasure glass, otherwise the ghost will know if he will step on the trigger switch."

Xiang Dongliu looked at the map, and was stunned when he saw that there was no mark on it, thinking to himself how the elites of the Huaxia Xuanyuan League in the past passed through this dangerous passage that was more than fifty meters long? Presumably at a great price, right?

After the thought flashed, Xiang Dongliu couldn't help but look at it suddenly, and immediately searched for it in the pile of white bones at the bottom of the passage under the night vision and perspective function of the perspective treasure mirror.

As expected, it took less than a minute to flow eastward before he saw two military necklaces that shimmered with a faint silver light. One at two o'clock and the other at ten o'clock.

It's just that the one that makes the eastward flow a little frightened is that the one in the direction of two o'clock is easier to take, and the one in the direction of ten o'clock is relatively troublesome.

On the surface, there is no difference between the military card necklace in the direction of ten o'clock and the one in the direction of two o'clock, but under the perspective, Xiang Dongliu found that the military card in the direction of ten o'clock is actually in a dangerous area, and there is a trigger mechanism hidden underneath, which will be triggered if there is a slight accident.

Seeing this, Xiang Dongliu couldn't help but stand still and smoke two puffs of cigar in a row, before he used the perspective mirror to look at the soles of his feet, and walked step by step to the military necklace in the direction of two o'clock.

After arriving at the position, Xiang Dongliu carefully picked up the military plate necklace at two o'clock, took it in his hand and looked at it, then hung it around his neck, and then set his eyes on the military plate necklace at ten o'clock.

"If you just reach for it, I wonder if it will touch the mechanism?"

Xiang Dongliu carefully looked at the switch at the bottom of the military brand necklace, and secretly weighed it for a while, and finally mustered up the courage to walk over, squatting down and carefully reaching over with the blood dragon tooth to pick it up.

Due to nervousness, Xiang Dongliu actually picked half of it for the first time, so he let the military necklace slip back, which frightened him, for fear that the small necklace would touch the switch if it fell to the ground.

However, what made the eastward flow suddenly loosen was that the necklace fell with little strength at this time, and the mechanism was arranged for a long time, so it was inevitable that there was some rust, so it did not touch the mechanism.

Just after understanding this situation, Xiang Dongliu decisively withdrew the blood dragon teeth, and with a very bold pinch of his two fingers, he put the second military necklace into the palm of his hand, wiped the dried blood slightly and hung it around his neck.

"The second one is here."

Xiang Dongliu muttered to himself, got up and bit his cigar and looked farther ahead, and found a military necklace again.

It's just that this military necklace is located at twelve o'clock in front of it, and there is a trigger mechanism under a large area around it, covering a distance of nearly four meters.

"The more dangerous the place, the more treasures are hidden, and it seems that the direction of this passage is not wrong."

Xiang Dongliu took a deep breath, thinking to himself that he couldn't reach it now, and he couldn't step on it, how could he get the third military necklace without triggering the mechanism?

After pondering for a while, Xiang Dongliu pulled out the blood dragon tooth again, gently placed it flat on the ground and gestured a few times, and after estimating the distance and measuring the strength, his right hand shook suddenly.

"Whoosh!"

The Blood Dragon's Tooth slid past the ground with a sound, and then, like a bulldozer, pushed the Badge Necklace out of the area covered by the trigger mechanism, sliding it to a safe place with the Badge Necklace.

Seeing that the impact method was effective, Xiang Dongliu naturally activated the Demon Shadow Boots in time, and with a slight click of his feet, he directly jumped over this dangerous area of nearly four meters, and landed next to the blood dragon tooth and the military brand necklace.

Immediately after, Xiang Dongliu bent down to pick up the blood dragon tooth and the third military brand necklace, and hung the necklace around his neck with a hearty smile on the corner of his mouth, looking through all the way, dodging the trigger area step by step.

It took a full five or six minutes to travel eastward through this dangerous passage of less than 100 meters.

If it is said that without the help of the perspective mirror, it may be difficult to flow eastward through this passage. Without the Shadow Boots, it would have been difficult for him to get his third Armor Necklace.

Therefore, after understanding the beauty of the See-Through Mirror and the Shadow Boots, Xiang Dongliu smiled more happily, and soon took a few leisurely sips of cigars at the end of the passage before recovering and going deep into the underground tomb.

It didn't take long for Xiang Dongliu to come to a room of more than ten square meters, and at the same time, he also found that there was a V-shaped staircase in the room, which was used for people to go down the stairs to enter the room, and to go up the stairs to leave the room from the other end.

The staircase is made of blue bricks, and due to the long time, there is still a sense of looseness of swaying when stepping on the eastward flow, so he is asked to walk step by step, very carefully.

At the same time, as he walked, he also used the perspective treasure glass to look ahead, left and right, and the situation above, and carefully investigated that there was no danger before he was willing to take a step.

However, there is a saying that people are not as good as heaven, and plans cannot keep up with changes.

Although he was very cautious about flowing eastward, when he turned left to reach the next room with a V-shaped staircase, he didn't know whether it triggered some mechanism or what, but he suddenly heard a dull roar, and at the end of the staircase that was sloping up in front of him, a male lion suddenly attacked!

It's just that this male lion is carved from stone, and its body is huge, with delicate lines and lifelike.
