The whole team immediately stopped.

"What's going on?" "What happened?" The person in the back asked.

A few of us and Professor Jin rushed to the front of the team from the middle of the team, and saw Cao Fenghua, who was walking in the front, and a few people gathered together, looking at something in their hands.

When Cao Fenghua saw Professor Jin and us coming, he hurriedly pushed away the few people around him, walked over and handed over the things in his hand to Professor Jin.

By the light of the flashlight, I could see clearly that Professor Jin was holding a bronze arrow in his hand, which looked like it should have been severed from the crossbow arrow. The arrow was already covered with green patina, as if to tell of the time it had spent here.

After Professor Jin looked back and forth a few times, he said affirmatively: "This is indeed a crossbow arrow from the Warring States Period. You see, this is a three-bladed sword, which is the most popular crossbow arrow style at the end of the Warring States period. It is more stable and directionalized than the traditional triangular arrowhead in the Spring and Autumn period. ”

Professor Jin turned to Cao Fenghua as he spoke, and asked, "Captain Cao, this is the only one you found?" ”

Cao Fenghua shook his head, then let go of his body, and shone the flashlight in his hand forward: "Professor Jin, look! ”

I saw that on the road not far from us, there were many crossbow arrows scattered around. Some are very complete, and some are like the one in Professor Jin's hand, the arrow and the arrow body have been separated.

Seeing so many crossbow arrows in front of you, even the stupidest person can imagine: there is a mechanism ahead!

I immediately thought of the iron ball that Situ Feng had used to explore the path and break the mechanism before. Although there are no ready-made tools at the moment, there are still alternatives that can be found. So I hurriedly asked someone to find some larger stones from outside and threw them on the road ahead. But unexpectedly, a few stones were thrown, and after rolling on the ground a few times, they stopped, and failed to trigger the mechanism at all.

"What's going on?" I asked curiously, "Is this trick not working, or is it that this mechanism has been triggered by everyone before?" ”

Master Liang muttered: "If the mechanisms here have been triggered by people, why haven't you seen any corpses?" Could it be that the people who came in before us and triggered the mechanism are not injured here? ”

"No, second uncle, that's a bit too good, right?" Liang Youcai said, "It's just a whole body retreat!" ”

Professor Jin said, "That's not true. As long as the robbers are forewarned and prepared, the crossbow arrows in the tomb may not be of much use. ”

"So what's next? Is it advancing or retreating? We're not sure if there's a mechanism in front of this? Lu Daxun asked.

"Return, it is specified that it cannot be returned!" Mo Ji gave a direct answer, "But what about this ......" He was also a little hesitant, after all, it was an impossibly matter.

"Enter, yes, but you can't rush in." Uncle Xu said, "I knew that there were tigers in the mountains, but I sent them to the tiger's mouth." We can't do this kind of loss-making business! ”

"What then?" Mo Ji asked.

Uncle Xu said: "Aren't they all wearing bulletproof vests? The first four people wore helmets to explore the way, and the rest took off a few more vests to give them and protect other places, just in case. ”

"Yes, yes, yes! That's it! Mo Ji clapped his hands and laughed and said, "No matter how powerful the thing is from two thousand years ago, it can still be more powerful than a gun?" ”

Professor Jin shook his head and said, "You must not underestimate things from two thousand years ago, the crossbow arrows in the Qin Dynasty were very lethal. After testing and recovering the unearthed copper crossbows, it was found that some crossbow arrows had a range even longer than a pistol. ”

Hearing Professor Jin say this, everyone was stunned again. I just thought of a solution, and I asked the experts to say no, so what can I do?

I only heard Professor Jin continue: "However, the mechanisms in this have been more than 2,000 years old, and look at these arrows are all rotten, and some of them even break when touched, and the lethality should not be so great." Moreover, the opportunity to shoot these crossbow arrows should not have much power after such a long time, plus so many arrows have been shot before, the force must be even smaller. ”

After listening to Professor Jin's analysis, we also nodded again and again.

"However, just like Mr. Xu said, just in case, you still have to take precautions!" Finally, Professor Jin added.

So, Lu Daxun led three of his subordinates, put on riot helmets, and tied the extra bulletproof vests around his waist, and at the same time, each of them held a bulletproof vest as a shield in their hands. They were all over the body, and only their limbs such as their hands and feet were exposed.

Lu Daxun formed a circle with his four faces outward and his backs inward, and moved forward little by little with great caution.

Seeing Lu Daxun and the four of them exploring the road in front, we were all worried. Especially when we got to the place with the most crossbow arrows in front, our hearts almost rose to our throats. Lu Daxun and the others were also very cautious, standing there for a moment, and seeing that there was no abnormal movement, they continued to move forward.

Seeing Lu Daxun and them moving forward safely, we finally put back our hearts a little. But at this moment, a "kakalala" sound rang out from the walls on both sides. It's like a wooden machine turning.

"It's a trap!" Someone cried out in horror.

Then I saw countless small holes on the walls on both sides, and crossbow arrows stretched out.

Lu Daxun had already stopped when they heard the strange sound. When he saw those outstretched arrows, his face suddenly changed.

At this moment, a bronze arrow protruding from the wall shot out like a thousand arrows. "Whoosh" bursts of breaking the air sound, endlessly, we are terrified when we hear it. It can be seen that although the power of those crossbow arrows has decreased after more than 2,000 years, they still have a lot of lethality.

Looking at the field ahead, those crossbow arrows hit the opposite wall under the action of the machine, and some shot on the ground, and the "clanging" sound of their collision with the stone continued one after another, stirring up countless sparks.

Lu Daxun and the other four desperately grabbed the bulletproof vest in their hands to prevent the arrows from entering.

"Look! These bulletproof vests are also really powerful, and not a single arrow can penetrate them! Seeing that Lu Daxun and the four of them were safe and sound in such a dense rain of arrows, the altar couldn't help but scream.

"Of course, how else would you call it a bulletproof vest? Can't even defend against bullets, let alone a few tiny bows and arrows? Mo Ji also said happily when he saw it.

Although the bulletproof vests in the hands of the four Lu Daxun can block the crossbow arrows, when the crossbow arrows are shot in their hands, they always shake their arms, which shows the power of the crossbow arrows. In fact, I also understand the principle of bulletproof vests, although they can block bullets, but when they are shot on people's bodies, the force is like a sledgehammer hitting the chest, and it can even beat people to the back. Although these crossbow arrows can't compare to the power of bullets, I guess Lu Daxun and the four of them are definitely not comfortable.
