Chinese pay attention to the soil after death, but human nature is greedy, so in Chinese tombs, the tug-of-war between tomb robbery and anti-tomb robbery has been ongoing.

The road is one foot high, the tomb robbers have derived their own tomb robbing technology, and the anti-theft people have also derived anti-theft technology, in ancient Chinese tombs, many tombs have set up a lot of deadly mechanisms, one is more ruthless than the other.

No, the wolf general, Anglo, Carl, Steel-blooded and others suffered from it, and if Ma Xuan hadn't gotten the map and the inheritance of the Golden Patriarch in advance, it is estimated that he would have been recruited like them.

However, there are also ways to kill people silently, such as poisoning tomb robbers with mercury volatile gases, which is a typical historical example of making full use of various means to fight tomb robbery.

The dungeon was filled with mercury, and it may have been motivated by the poisonous mercury vapor to kill the diggers. At that time, people would not have noticed the phenomenon of mercury poisoning, and it was natural to use this property of mercury for anti-theft design.

No, everyone was tricked again, but they didn't know it, only Ma Xuan took precautions in advance, and did not inhale the gas with mercury in the air, this kind of thing can be saved if it is sucked less, but if it is ingested in large quantities, it will be over.

Soon it was the fourth level, this time they were going to be unlucky, Ma Xuan just stood still, waiting for them to step on the thunder first.

"Haha, boy, why don't you leave? Could it be that you are cowardly, just say it directly, since you are cowardly, I am not polite to the treasures in front of you. ”

Ma Xuan didn't pay attention to it, because who was instigated would be known in a while, and there was no need for him to show off his power there.

Anglo embarked on the fourth level of this ancient tomb: the chain flipper.

The chain flap, that is, digging a pit about 3 meters deep in the mausoleum tomb road, the length and width depend on the specific situation of the tomb road, and the knife and cone sharp weapon of about 10 cm are distributed under the pit.

The upper layer of the pit is covered with several wooden planks, with a shaft in the middle of the plank, and a small object of the same weight is decorated with a small object of the same weight, in the shape of a balance scale, and there is a cover on the board. If a grave robber steps on a plank, one end of the board sinks, and the person will fall onto the cone in the pit, and the sharp blade will penetrate the chest and internal organs of the grave robber, and the probability of crawling out alive is almost zero.

Seeing this, Anglo quickly spread his wings to dodge, but it was not over, followed by another mechanism in the fourth level: the Rope Hanging Stone.

Similar to the function of the chain flap, it is a cable hanging stone. It is mainly to fix a number of metal pulleys on the top of the tomb and the hidden place of the wall, and use the pulleys to lift the boulder and hang it at the top. The cemetery is paved with wooden seesaws, and the cable chain is lowered from the stone slabs, and the rockers are connected in a concealed way by pulleys, and there are hooks and unhooks in the middle, which can automatically fall off when pressed by external forces.

There are many iron cables used to hang stones in the ancient tombs, and after everything is completed, they are disguised so that outsiders do not know about their deception. If a tomb robber enters the door and steps on the stilt, the external force forces the tight rope chain to fall off somewhere in a hook, just like the wheel of digging a well suddenly relaxes, and the hanging boulder falls rapidly, slapping the tomb robber who can't dodge into a meatloaf.

So as soon as Anglo flew up, he was slapped aside by a boulder that suddenly flew over, unconscious, and was directly knocked unconscious.

The mechanism of the fourth level was all explored by Anglo, and Carl used teleportation magic to bring back the unconscious Anglo, preparing to break through the fifth level, and after passing the fifth level, this is about to reach the end of the tomb.

Karl stands in front of him to meet the sixth level: Ambush Fire.

The so-called "ambush fire" can "fly flames" and have the effect of burning grave robbers. This type of tomb is called "fire pit tomb" and is a type of tomb unique to the southern region, but few are found in the north.

According to analysis, the cause of the fire in the "fire pit tomb" may be caused by the decomposition of organic matter buried in the tomb to form a combustible gas - biogas.

In ancient times, there was a type of tomb called "fire pit tomb" because it contained an unknown gas that could burn, and the burning gas in the fire cave tomb was probably methane produced by the decomposition of corpses.

So what is the principle of the fire cave tomb? As we all know, in the process of decay of organic matter, in the absence of oxygen, a large amount of combustible gas - methane, that is, biogas.

In the case of a particularly well sealed burial chamber, especially if the coffin is tightly sealed, the gas collects in the coffin for a long time, and when the coffin is suddenly opened, if the methane encounters an open flame, of course, it will ignite at all. This is what is often referred to as a fire cave in tomb robbing.

Although digging a fire hole is very dangerous, many gravediggers are very willing to touch the fire hole, and the presence of a fire hole indicates that the tomb is well preserved.

I saw that the flames were blazing, directly wrapping Carl inside, the fire was fierce, Carl couldn't get out, so he had to put up the protective cover first, but although the protective cover was propped up, it still had to withstand the high temperature of the steamer.

With the last of his strength, Carl unleashed a spell: the Waves, and when he was done, he saw the water elemental merge into a wave, extinguishing the fire, and then Carl fell down.

Then Steel-Blood carried the banner of Carl and prepared to break through the sixth level, and after passing the sixth level, he really saw the light of day.

The sixth level is the Saimen knife car, and some tomb owners use the ancient Saimen knife car in the tomb as an anti-theft hidden weapon. The Saimen Knife Carriage is a defensive device used to block the city when the city gate is attacked.

There are 24 steel knives on the front knife wall, and when used, the cart can be pushed to the gap in the city gate, which can not only kill and injure the enemy, but also block the enemy's arrows and stones. In this way, it is difficult for the other party to climb and form a barrier to activity.

The knife cart is a kind of extremely strong two-wheeled vehicle, the body of the car is almost the same width as the city gate, usually always between three or four zhang; there are three or four layers of wooden frame in front of the car, and each layer is fixed with a number of sharp knives, and the body of the car has a long wheel; once the enemy breaks through the city gate, dozens of hundreds of soldiers push the knife cart to block the city gate.

I saw that the knife cart rushed directly towards the steel blood, and the steel blood had nowhere to avoid, so he had to resist the attack of the knife car that could break the city.

Steel-blooded used his steel arm to resist the attack of the knife cart, but he was not much better, how could he break the power of the city?

Although he blocked the advance of the knife cart, the cost was also staggering, and all the internal parts of his steel arm were destroyed......

After these six passes, the wolf general, Anglu, Carl, steel blood, big and small, are all injured, just like Ma Xuan is like a nobody, just like that sentence, the insider looks at the doorway, the layman looks at the excitement, Ma Xuan is a layman who doesn't follow them to stir up, and becomes a bastard of the whole situation.

There is no harm in six passes and six links, on the other hand, the enemy army is defeated......
