Qi Ziyu quickly followed Zhou Sheng's instructions.
He first removed the candle from the first lamp, and then lit the second lamp again in the same manner as before.
Immediately afterwards, the bricks on the only wall began to fall off.
Sure enough, as Zhou Sheng expected, when all the lamps are lit, it seems that the shielding mechanism of the mechanism will be triggered, causing the mechanism on the lampstand to temporarily fail.
Zhou Sheng couldn't help but marvel at the wisdom of the ancients again. Although he had seen the designs in many tombs, this was just a little-known tomb. But the design of this mechanism was still very interesting.
When the tomb was first built, as long as eight lamps were lit at the same time, the mechanism would not be triggered.
Then, as long as the fuel content in the lamp is kept consistent, the burning speed will be almost the same underground where the air flows slowly.
Therefore, when the fuel is burned out, the eight lamps will be extinguished together, and the mechanism will not be triggered.
The murals behind this wall can be preserved to this day, waiting for future generations to discover.
However, as the bricks and stones on the second wall were scattered, the last half of the painting did not appear in front of Zhou Sheng.
Instead, there was a layer of charred black soil.
The wall seemed to have been corroded by some kind of strong acid, and all the murals on it had been destroyed!
"Could it be that the wrong way just caused the mural to be destroyed?" Qi Ziyu asked doubtfully.
"This is the only possibility."
It seems that once the mechanism is not opened correctly, not only will the poisonous mist seep out, but the murals will also be damaged.
Not seeing the second half of the painting made Zhou Sheng a little regretful, but he had already determined the next path.
Just now, under the illumination of eight lights, the shadows of the coffin here began to overlap, forming an arrow-like pattern!
And all the arrows point to the center of the tomb.
Zhou Sheng had previously discovered that there was a small bump on the ground in the center.
There is no doubt that there must be a way down here!
At present, the poisonous gas in the tomb has become thinner, and it seems that it has spread a lot along the corridor.
In this case, the group can return to the tomb while taking good protection, continue to explore downwards, and trap the poisonous gas above.
After Zhou Sheng and Qi Ziyu returned to the corridor, they informed everyone of their findings and plans.
Naturally, these few people had no reason to refute.
Although the poisonous gas is thin, not everyone has Zhou Sheng's physical fitness, let alone Qi Ziyu's weird ability to resist poison.
If there is a chance to go to a drug-free space, naturally no one would want to stay in a drug circle.
Everyone spent a lot of time going back and forth. When they came to the door of the tomb again, Zhou Sheng suddenly felt that something was different in the tomb.
Except for the one lamp that Qi Ziyu extinguished before, the other seven lamps were still on, allowing them to see clearly the scene in the tomb.
The bricks and stones below the mural are still piled up in a messy manner, and the rows of coffins are still neatly arranged.
Nothing seems to have changed, and the content on the mural is the same as what I just saw...
——Wall!!
Zhou Sheng suddenly stared at the wall where the mural had been destroyed. The scorched black spots on it were spreading outward at an extremely slow speed.
This wall is being corroded!
The scorched black marks on it had changed significantly from the last time Zhou Sheng saw it.
However, most people would not remember the corroded lines when they see a bunch of meaningless charred marks, so Zhou Sheng was not able to immediately discover that the charred wall had changed.
It wasn't until this moment that he realized that the wall had moved back a few millimeters. It was obvious that these few millimeters of soil had been completely eroded away.
This also means that behind this wall, there are highly corrosive materials that have not been used up.
At this moment, the corrosion on the wall suddenly became violent!
Visible to the naked eye, the earthen wall looks like it is on fire. The mud and sand are peeling off layer by layer, and the blackness continues to spread!
But the corrosion is limited to this wall, and the murals on the left and right sides of it are all intact, as if the edges of the murals are some kind of insulator, isolating all phenomena on the middle wall.
The wall receded at a speed visible to the naked eye, as if countless invisible termites were eating the soil, and the wall became thinner and thinner.
"Bang!"
With a loud bang, a stream of water broke through the wall and sprayed into the tomb!
But when the water spilled onto the coffin and the ground, it made a sizzling sound.
"This is not water, this is strong acid!" Xiao Zhang shouted in panic.
Fortunately, Zhou Sheng stopped a few people outside the tomb when he felt something was wrong, so no one was drenched by the strong acid flow at this moment.
It seems that this strong acid has been corroding the wall. When the mechanism was accidentally touched just now, the strong acid has been released. It first corroded the content on the mural, and then, during the time when several people were going back and forth, the entire wall was corroded.
The earth wall is corroded and penetrates the layer!
However, not long after the strong acid was sprayed, the acid flow began to gradually decline. It seemed that in a few dozen seconds, the strong acid would be exhausted, and everyone would not be drowned by the acid.
"It's not good!"
Before everyone could breathe a sigh of relief, Qi Ziyu quickly pointed to the position of the coffin and shouted.
Under the strong acid, a chemical reaction of iron element replacement is taking place on the coffin board, and the rust on the edges is also falling off!
If this continues, the coffin will definitely be broken open by the strong acid.
No one knows if the coffin is opened and whether it contains a treasure or a rice dumpling.
Of course, it is also possible that it is just an ordinary withered corpse.
Xiao Zhang stared at the coffin board closely, and his breathing became rapid.
His physical fitness is not as strong as Zhou Sheng's, and his resistance to the poisonous mist is also even worse. Even now, his eyeballs are still very sore, and tears are still rolling down his eyes.
But Xiao Zhang didn't want to close his eyes, he was afraid that he would miss a crucial scene!
Others thought he was worried and nervous, afraid that something unclean would escape from the coffin.
Only Xiao Zhang himself knows that deep down in his heart, he actually expects to see those things that only exist in novels!
Of course, Xiao Zhang knew that his expectation was like Ye Gong's love for dragons. Once the terrible rice dumplings really appeared, he would have no choice but to run away crying.
But people often have this kind of rebelliousness in their psychology. Even the most obedient and honest people will have rebellious thoughts at certain moments.
Just then, the coffin moved!
Xiao Zhang's expectation came true. There was indeed something evil in the coffin, and it was still pulling at the walls of the coffin, as if it couldn't wait to get out.
As the degree of corrosion deepens, the coffin panels shake more and more violently.
Several people seemed to have forgotten the discomfort of being poisoned. They all held their breath and stared at the coffin board attentively, always feeling that it would be overturned in the next moment!
