Everyone has entered the iron bridge, what surprised me was that the few bodyguards who followed behind us, a few middle-aged uncles entered such a hot place, and they didn't sweat a drop of sweat, all the time, they didn't say a word, and even the expression on their faces didn't change much.

Yan Jing took off her coat and tied it around her waist casually, her already Miaoman's waist was strangled by the coat, and her proud figure became more obvious, and she was wearing a white tight sweatshirt inside, and you could vaguely see the pink underwear inside......

The iron bridge can allow the two of them to walk side by side, Yan Jing and Chen Xuerou in front of them walked together, and they all said that beauties are familiar with each other, and this is really the case, in such a hot environment, the two beauties chatted happily in front of Huo Nan and me.

Huo Nan, the kid, stared at Yan Jing's back and swallowed his saliva, slipped under his feet, grabbed the iron chain with the thickness of his arm on the side, and then let go like a pig.

"Wow, it's so hot!"

I glanced at Huo Nan's hand, it was really hot, and the whole palm was red: "Be careful, you kid, sooner or later you will die on a woman's belly, wasting your good skin." ”

Huo Nan nodded stupidly, glanced at the rolling magma below, and couldn't help but shrink his neck and said: "You're right, it's better to be careful, falling from such a high place, don't look at the magma below, it's no different from falling on the concrete floor." ”

The heat rising under my feet tested the tactile nerves of everyone on the bridge, and I miss the feeling of the breeze on my face now.

"It's still our ancestors who are powerful, so long ago, they could build such a large bridge, I'm curious about how they built it in the first place, and it's on this magma, even with the current level of technology, it's not easy to build a bridge on the magma." Huo Nan said with some embarrassment.

"yes, it's hard to build something on top of that, but ...... You also use your brain to imagine, building a bridge on the magma, with the current level of construction is impossible, you still learn architecture, put it thousands of years ago, it is even more impossible, this is not a matter that can be solved by human and material resources, as for how to build this bridge, just imagine it from another angle, this magma may have been attracted by the ancients, or, it came out later. I gave Honan a satisfactory answer.

In fact, it is easy to imagine that in ancient times, it was impossible to build bridges on magma without large-scale construction equipment.

"Not necessarily......" Chen Xuerou heard our words, turned to look at me, and then a charming smile was drawn on the corner of her mouth, and I was stunned when I looked at it.

"Could it be that it's really covered on top of the magma, it's too." I pouted.

"If it's not good down there, what about above?" Chen Xuerou raised her head and motioned for me to look up.

I was stunned when I heard this, and then looked up, only to see that the giant stone pillars with a diameter of five meters were directly inserted into the top of the cave, and along with Chen Xuerou's words, I thought down, if a model hole was dug out from above, the cement was poured down, and then the bottom was sealed with chains, layer by layer, it can really be done, just like the current construction of the steel bar is fixed first, so that the concrete is poured directly, no wonder this big iron bridge can stand for thousands of years.

For Chen Xuerou, my feeling is becoming more and more mysterious, I don't have any poisonous eyes in my old profession as a student of architecture.

Relative to modern science and technology, ancient people, what they have is time and manpower, and both of these are almost endless, modern construction budget for ten years, has been very little, generally within three years can be completed acceptance, and in ancient times, the emperor will build a mausoleum, the time spent is not only, this is not only at home, but also abroad, those huge family and royal blood members, for the mausoleum after death, to spend several worlds digging pits, and the cost of manpower and material resources, It's all astronomical.

I was thinking about what the bridge was built for, and suddenly, I felt an irrepressible sense of irritability in my heart, and I shook my head, my tongue was a little dry, and I thought it was my own delusion.

"Not good! Let's go! Zhang Moxing, who was opening the road in front, stopped, turned around and said loudly to the back.

Zhang Moxing's actions made us nervous again.

"Boom!"

There was a loud bang, and the entire iron bridge trembled, and the broken stone from the top of the cave above began to fall directly, and after falling into the magma below, it was directly swallowed and melted.

"What happened? Such a big move! Isn't there any trap or something on this bridge, we're so unlucky? Huo Nan grabbed my shoulder and couldn't help but ask.

"It's going to be the bridge soon, speed up, go out first." I also chuckled in my heart with that loud noise, and it seemed that the feeling just now was not groundless.

A group of people began to run wildly with Mao Gose, originally a distance of more than 100 meters, if you sprint with all your strength, you can pass in more than ten seconds, but with that loud noise, the bridge suddenly began to shake, it is difficult to stand on it, and it is rolling magma below, and the psychological effect makes it difficult to exert the speed.

"Bump! Bang bang ......"

There were a burst of muffled sounds, as if something had knocked the door open, and my head exploded when I heard them.

"Chirp...... Haw...... Roar! ”

With a few loud giant beast roars, the voice of the group of mutated rats that had disappeared for a while came again.

Hearing these voices, everyone also understood what was happening, and then thought of the hundreds of bronze ancient doors in the hall just now, I don't know how many things will come out now.

As expected, the big rats smelled people and rushed in through the secret door.

The middle-aged uncles who had broken off held the black submachine gun behind their backs in their hands, and their faces did not change while waiting for the rats to enter the firing range.

"These guys are really haunted...... I said, pouting as I ran.

The speed of the rat colony is very fast, and from time to time some rats deviate from the runway and are squeezed down directly, seeing that they are rapidly getting closer.

After seeing that the rat swarm entered the firing range, the four middle-aged bodyguards were the first to shoot, but they did not fire at full power, but carried out spot fire very regularly, and the efficiency of cleaning up the rat swarm was very high, and one bullet could kill a few.

The four of them were two in front and two behind, and when there was nothing to do with Mao Gose's subordinates behind, they were also happy to be idle, and while retreating quickly, they were ready to go up at any time.

Soon, there was a rain of rats in the air, heading towards the magma below, and each mouse that fell on it finally broke out with a hiss, and then the body burned directly, and soon the whole body fell into the magma and disappeared.

"Chirp! Chirp ......"

Suddenly, the rats running at the front slowed down a bit, and then freed up a passage of about a meter from the middle.

And in the passage, suddenly there were dozens of rat kings that were many times larger than ordinary rats, each of which was the size of an adult wolf dog, and in terms of combat effectiveness, it is estimated that the rat king has always been able to single-handedly take on the Tibetan mastiff, and the speed is even faster and scary, and the cheetah-like run wildly, and in the blink of an eye, it rushed out of the rat group.

I looked back and was directly stunned, this mouse is too exaggerated, right? Not only the body shape, but even the hair has been mutated, with a hint of metallic texture, the muscles all over the body are bursting up, giving people a very wild feeling, and the appearance is so eerie and terrifying, the little girl is about to be scared to cry, Tang Youyou's pretty face in front of me is originally white, but now it is all white.

It seems that the bronze ancient door in the hall where we were just now is estimated to have one such rat king, and their treatment must be like emperors, and everything delicious is given to them, no wonder they grow so big.

"There is such a big guy, it seems that he should be able to take more machine guns, it is estimated that it is not easy to deal with, guys, prepare for a cold war, you must protect Miss Yoyo." Of the four middle-aged bodyguards brought by Chen Xuerou, one of them seemed to be the leader.

The boss has a long scar on his face, from the corner of his mouth to his left ear, which looks a little scary.

Before the words fell, an amazing scene was produced in front of the eyes of several people, and those mutant rat kings actually relied on their flexible bodies and outrageously sharp reflex nerves to dodge the bullets fired by several people!

These mutant rat kings, each of them with an agile posture that normal people can't understand at all, are dodging the bullets of the submachine gun, and only a few of them hit the bodies of the next few without dodging, but it seems that the effect is not very ideal, and it did not hit the vital point, this mutant rat king with rough skin and thick flesh, after receiving a few shots, did not lose his combat effectiveness.

Amazing defense and agility!

The four of them were just surprised, but they didn't panic at all, if they really wanted to talk about strength, they wanted to be at the same distance, and it was not a difficult thing to dodge the bullets of the submachine gun with their skills, but it was a hand-to-hand fight with these mutated rat kings, they were more excited, and their eyes began to breathe fire, and the corners of the leading scar man's mouth outlined a bloodthirsty smile.

Dozens of mutant rat kings have already pulled away the rat troops behind them for a distance, and seeing that there are still dozens of meters away, they are about to face the four middle-aged bodyguards behind.
