Sensing the abnormality, everyone became vigilant.
Then, they began to move forward carefully. As they continued to move forward, the wind blowing in their faces became stronger and stronger.
This time, they walked for about two minutes.
Suddenly, the wind in front of them became weaker, which meant that they might be very close to that open area.
"Ying Xue, be careful…"
Thinking of the key point, Yang Shurou reminded without turning her head,""We might be very close to that area. I'm not sure what's ahead.”
That's right.
The wind had weakened, which meant that they were very close to the open area.
Under such circumstances, even Yang Shurou herself had to be cautious. Otherwise, no one could be sure if an accident would happen in this unfamiliar environment.
This was what Zhang Qiu had taught her back then.
No matter how strong he was, he still had to be vigilant when facing an event.
After all, the most dangerous thing for them was the unknown.
As expected!
As they continued walking for a minute, the originally narrow tunnel disappeared and was replaced by a large natural underground mountain stream.
At this moment, everyone was standing at the edge of the cliff. On the left and right sides of the mountain stream were two unknown areas that extended into the darkness.
Under the cliffs on both sides of the mountain, there was a narrow foothold that was less than a meter long, extending all the way into the darkness.
Everyone subconsciously looked down.
Gulp!
Instantly, the few people present could not help but swallow their saliva.
This was because the mountain stream under their feet was a pitch-black abyss. If they fell down from here, they would definitely be smashed into pieces. They could not even see how deep it was.
At the same time, they looked up.
There was a ragged suspension bridge under their feet, which directly crossed the mountain stream in front of them and connected to the cave under the opposite rock wall.
It seemed that they could only go deeper into the tomb through this suspension bridge.
"Retreat!"
Seeing this, He Hongbo quickly called everyone to retreat.
If he accidentally stepped on the air and fell, the pieces would definitely be more broken than Lego!
At the same time, the netizens in the live broadcast room were also shocked by the underground mountain stream in front of them.
"This... This isn't a movie, is it?"
"How can there be such a vast underground mountain stream inside a burial pit?”
"It can't be wrong. I saw it with my own eyes.”
"F * ck! His scalp went numb. This mountain stream could be said to have hollowed out a space the size of a football field underground, right? How much manpower and material resources would that take?"
For a moment, the people in the live broadcast room started to comment. No one could imagine how the ancient people dug such an underground mountain stream deep underground.
"Sister Shurou."
At this moment, Zhang Yingxue could not help but ask,"Are we going to cross this suspension bridge?”
What a joke!
Although it seemed that this suspension bridge would allow them to continue deeper into the tomb.
However, after so many years, who could guarantee the safety of the suspension bridge? It would be terrible if it broke.
Yang Shurou frowned and said,""If nothing goes wrong, this suspension bridge is the best route.”
"However, if this funerary pit was built during the Qin Dynasty, then no matter what material was used to build the suspension bridge, it would probably have been severely oxided by now. It is very likely that it would not even be able to support the weight of a person.”
That's right.
It had been too long.
Even if Yang Shurou was confident that she could make it, what about Zhang Yingxue and the rest?
But at this moment, Professor Wang suddenly said,""Not necessarily. According to our previous exploration of the burial pit of the First Emperor's mausoleum, we found that most of the metal products in the Qin Dynasty burial tomb were made of bronze.”
"After the anti-oxidization measures, these bronzes still retain their high density and toughness, so if we cross the bridge one by one, we might be able to hold on.”
Hearing this, everyone fell into deep thought.
public and public
However, if they were to step onto the suspension bridge, they might have to pay the price with their lives.
In the end, Zhang Yingxue, who had been silent all this while, suddenly suggested,"Perhaps we can find a substitute to test the weight of the suspension bridge…"
Hearing this, everyone present nodded.
After some discussion, they found a few rocks that were heavy enough and threw them into a backpack. Then, they threw them toward the suspension bridge.
Bang!
The backpack that was filled with rocks weighed at least 60 to 70 pounds. When it hit the suspension bridge, it caused the entire bridge to shake violently.
The few of them quickly looked over and saw that although the suspension bridge looked shaky, it was still holding on. However, just as they thought that they were safe and sound, a cluster of flames quickly ignited where the backpack rubbed against the suspension bridge.
The blue flame burned slowly for about ten seconds before it slowly extinguished.
Hiss!
Seeing this scene, everyone present sucked in a cold breath.
At the same time, the netizens in the live broadcast room also exploded.
"F * ck! Why is it burning?"
"What happened? What's going on?”
"Why is there a flame? Moreover, why was the flame blue?”
At this moment, Zhang Yingxue swallowed her saliva when she saw the blue flames.
Fortunately, they had taken precautions.
If he had rushed up earlier, he would have been burned to death, right?
But at this moment, Yang Shurou carefully looked at the stone slab on the suspension bridge in front of her. A few seconds later, she suddenly seemed to have discovered something.
"No, this isn't a raging fire!"
Yang Shurou pointed at the stone slab on the suspension bridge and analyzed it seriously." Look, the stone slab has been burned by the flames, but there are no traces of it being burnt. Moreover, the flames are blue!”
"If I'm not mistaken, the blue flame just now should be a phosphorous flame.”
"This suspension bridge should have been smeared with white phosphorous, which is why the stone would burn with blue flames when it rolled over.”
What was that?
Hearing Yang Shurou's words,
Upon closer inspection, they were enlightened.
That was really the case.
There were no burn marks on the stone slab.
Not only that, but if one looked closely, one could also see that there seemed to be a layer of alkali-like substance attached to the stone slab of the suspension bridge.
Upon realizing this, everyone present heaved a sigh of relief. However, when the netizens in the live broadcast room saw this scene, some of them did not understand.
"What is the meaning of this?"
"Yeah, what does a wildfire mean? Is it a blue flame?”
"The person above doesn't understand, right? Let me explain it to everyone! This was a chemical reaction. The so-called white phosphorous was a chemical substance, and its most striking feature was its extremely low ignition point. Even the slightest air friction would ignite a flame. The flame was blue, but this flame was a cold flame at zero degrees. Even cotton could not be ignited!”
"F * ck! There's a surprising scientist upstairs!"
"The person above is right. Moreover, white phosphorous has a good antiseptic effect. If it is applied to the suspension bridge, it will indeed be a good antiseptic measure!”
