Two soldiers from the Eastern Dynasty walked on both sides of the drawbridge, one on the left and one on the right, carefully holding on to the iron chains on both sides of the drawbridge, for fear that the drawbridge, which had existed for an unknown number of years, would suddenly break, or that the wooden planks on the drawbridge would collapse.

Chen Ziyang, who was standing in the middle of the team, carefully looked at the suspension bridge. The entire suspension bridge is made up of five wrist-thick chains. There are three on the lower floor, which are covered with wooden planks, and one on the left and right of the upper floor is used as a handrail. I don't know what kind of wood is used for the planks on the suspension bridge. After all these years, although some places have been damaged, the overall condition seems to be relatively good.

The two soldiers carefully grasped the handrail and walked forward, and before each step, they first stepped on the place where they were about to land with a relatively strong step, and looked at the solid plank under their feet before continuing to walk forward. The two men walked a distance of several tens of meters, and nothing happened. So one of them stopped, waved to the group behind them, and told everyone to follow.

The people in the team were in groups of two, leaning on the side, stepping on the edge of the chain under their feet, holding on to the handrail of the chain and slowly walking forward, and when Chen Ziyang and Yang Lei walked on the suspension bridge, the first two soldiers were about to walk to the middle of the bridge. Chen Ziyang held on to the chains of the suspension bridge and walked forward cautiously step by step, avoiding some places where there were no planks on the edge of the chains or where the planks did not look solid.

At the beginning, the condition of the suspension bridge was good and relatively stable, and Chen Ziyang and Yang Lei walked relatively fast, but after they walked a distance of dozens of meters, the suspension bridge shook more and more. As the number of people walking on the bridge increased, the shaking of the suspension bridge became more and more serious, and even the suspension bridge shook violently, almost shaking Yang Lei down, so frightened that he tightly held the chain and did not dare to let go.

If a large number of people cross the bridge at the same time, it is not possible to adopt a uniform pace, because if the pace is relatively consistent, it is easy to cause the resonance of the bridge body, which can easily lead to the collapse of the bridge. However, there is also a disadvantage when walking, that is, the bridge shakes very much, and the shaking is very uneven, and the sudden shaking can easily shake people under the bridge.

Seeing that the current shaking amplitude of the suspension bridge could no longer allow people to continue walking, the leading general of the Korean side shouted, signaling everyone to stop, and then let the first few groups of people slowly move forward, reducing the number of people walking on the bridge at the same time.

I have to say that this method is still very effective, everyone stopped holding the chain, and the shaking of the suspension bridge is not so serious. Chen Ziyang, who was parked on the bridge, had more time to think, and as soon as he stepped on the suspension bridge, he felt that something was wrong, but he couldn't feel that something was wrong.

Looking at the bottomless abyss under the bridge, Chen Ziyang only felt dizzy, the darkness in this abyss seemed to be like a black hole, with special suction, and if you look at it for a little longer, it will make people feel that they have been sucked in, Chen Ziyang quickly focused his attention and gaze on the chain in his hand.

Looking at the iron chain with the thickness of his arm, Chen Ziyang suddenly realized what he felt was wrong, that is, this suspension bridge was too strong! It's understandable that the suspension bridge is strong, but what is this place? This is a tomb, and what is the most feared thing about the tomb? It's stolen. If the suspension bridge was built so sturdy to facilitate the transportation of building materials, why was it not destroyed after the tomb was built?

Even after the personnel who built the tomb were evacuated, the chains could be broken at the other end of the drawbridge, and the abyss, which was hundreds of meters long, was undoubtedly the best anti-theft mechanism, and there was no way for people to cross it. Thinking of this, Chen Ziyang couldn't help but admire the craftsmen who built this tomb, such thick, long, and heavy iron chains, and he didn't know how they were built on such an empty abyss.

Later, Chen Ziyang studied the suspension bridge again. It doesn't make sense, Chen Ziyang thought to himself. Whichever way you think about it, there is no reason for this suspension bridge to exist. Is it because something happened that the drawbridge could not be destroyed? Or is the owner of the tomb not worried about anyone coming to rob the tomb at all? Or is there some mechanism on this suspension bridge?

Then Chen Ziyang denied his idea one after another, the structure of this suspension bridge is simple, the chain is strong, and the entire bridge is unobstructed, there is no mechanism at all. The construction time of such a large tomb is at least more than 10 years, and there is nothing when it is impossible to build the tomb, but something happened in a split second after the construction of the tomb, resulting in no way to destroy the suspension bridge, which is too small. As for the owner of the tomb who is not afraid of being stolen, this idea is even more ridiculous, judging from the previous suspicions and various mechanisms, the owner of the tomb is simply afraid of robbing the tomb to death.

Chen Ziyang, who couldn't figure it out, inadvertently glanced at the chain on his hand again, but found that there was a layer of black stuff stuck to his gloves. Weird, what is this? When was it glued? Chen Ziyang took the gloves in front of him, pinched them with a few fingers, and found that this kind of thing was sticky, as if it was something like grease, and the color was black.

Bringing the gloves close to his nose, Chen Ziyang carefully sniffed the black thing on the gloves, even in the air full of pungent smells, he smelled a smell that he was very familiar with. Chen Ziyang recalled that the taste was somewhat like the lard boiled at home in the past.

Cut the fat of the pig into pieces and put it in an iron pot, boil out the oil, and the remaining shriveled fat pieces are called oil zila, and the oil boiled out is lard, pour this oil into a pot and put it at room temperature, and after a long time, this oil will present a white paste. When Chen Ziyang was young, he liked to eat oil the most, and when Lao Dao dealt with the blood spirit coffin, he also boiled this kind of lard. In the old days when the standard of living was not good, people used this kind of lard for stir-frying and cooking.

But when the lard solidifies, it is white, and the oil is black. Later, Chen Ziyang also found a lot of this black oil on his sleeves and clothes, and then he found that this kind of thing was smeared on the iron chain, and there is still a thick layer on the iron chain. It is estimated that the people who left before and after also rubbed this oil-like substance.

This kind of oil is very adhesive, although everyone has rubbed a lot on their bodies, but there is still a thick layer on the iron chain, Chen Ziyang took out a knife, carefully scraped it on the iron chain, looked at the pile of black oil on the tip of the knife and thought, is these things smeared on the iron chain for corrosion? Chen Ziyang thought of engine oil, and the reason should be the same.

But then recalling the corpse demon who was burned into black charcoal by himself before, Chen Ziyang shouted in his heart: Your sister, this should be corpse oil!
