Seeing the hope, everyone suddenly had momentum, and instantly rushed in and began to carry the gravel inside.

Li Xun leaned against the stone wall and took a breath, watched everyone's actions, and said, "Captain Zhang, your secret weapon can come in handy." ”

Captain Zhang was stunned: "What?"

Li Xun pointed to the top of Dragon City: "Accelerate the collapse, if it collapses slowly like this, it is easy to have an accident." The next fierce medicine made it collapse sharply. ”

Captain Zhang rolled his eyes: "What are you kidding, it's not that I'm reluctant to give up this thing, it's that this top wall is dozens of meters high, and there are vertical cliffs all around, how can you place it?

Li Xun smiled and said, "Who said I was going to go up and put it?"

"What then?" Captain Zhang wondered.

"How many seconds is the delay of your explosion?" Li Xun continued.

"0.1 seconds. Captain Zhang said very simply.

Li Xun was speechless for a moment: "Instant explosion?"

"Yes!" Captain Zhang looked proud.

"Hehe, are you Zhongnanhai's bodyguard? Do you have such a way to protect important people? Aren't you just pulling important people and enemies to their deaths?"

Li Xun was embarrassed, he was puzzled at the beginning, how could a bodyguard carry explosives with him?

Now it's even more depressing, a bodyguard, the explosives he carries with him actually explode in an instant, and the power may be huge, how can there be such a bodyguard.

Captain Zhang didn't want to say more on this issue, but said with some deep meaning: "Sometimes, it's not people who are protected, but some ...... Hehe, you say, what do you want?"

"It's a secret that is being protected, right?" Li Xun guessed and understood a little.

Captain Zhang is not protecting anyone at all, but protecting some people with important secrets, and if the situation is not right, the whole army will be wiped out and everything will be destroyed.

Probably so, Li Xun who is more detailed doesn't know.

"What do you want to do?"

Captain Zhang changed the subject and did not answer this question.

Li Xun said: "Can I set a delay?"

"How many seconds is the delay?"

"Four seconds is enough. ”

Captain Zhang nodded and said, "Yes, but I won't." ”

“……”

A moment later, Captain Zhang came from the hidden corner and took out the hidden weapon that had been hidden in the hidden part of his body.

It wasn't a bomb, it was just a bandage similar to a legging, elastic, light and not thick, and you couldn't tell it was a bomb.

You don't have to think about it to know that this thing has actually been hidden on Captain Zhang's leg, he is tied to his thigh and can be carried with him anytime and anywhere.

There is a wire attached to the bandage, which is very thin, thinner than the headphone cable.

At the end of the wire, it was a plastic patch the size of a band-aid, and there was nothing special about it, but there was a raised button on it.

Li Xun took the bomb and threw it to Lin Qingshan: "Do you have a way to make it a delayed blast?"

Lin Qingshan took the bomb and looked at it for a moment, and asked, "What is this?"

“…… Bomb. ”

Lin Qingshan exclaimed: "This turned out to be a bomb?"

Captain Zhang sighed: "Don't make such a fuss, you haven't seen too much, can you change it?"

Lin Qingshan beckoned to find a soldier who was moving stones and threw the bomb to him: "This is a bomb, can it be changed to a delayed blast?"

The soldier frowned and looked at it for a while, then said, "This is a smart bomb." It's electronic, it can't be changed, it's not some lead blasting, there's a computer program here. You see, this thin hole is actually a USB interface, and you need a computer to do it. ”

Lin Qingshan was stunned: "What kind of bomb is this, so advanced, and there is a USB interface?"

"Anyway, I can't change it, I have to use a computer to operate, and even if I have a computer, I can't get it, I don't understand this kind of programmed bomb, I only understand traditional blasting. ”

Captain Zhang shrugged his shoulders and said to Li Xun, "I knew it wouldn't work." ”

Li Xun didn't answer this question, and said to Lin Qingshan: "Have you cleaned it up?"

"It's cleaned up, and there's still some rubble, but that's okay, it doesn't get in the way of our safety. Lin Qingshan said.

Li Xundao: "Have you set up the reinforced bunker inside? Although I am not worried about the secondary collapse, it still needs to be prevented." ”

"It's done, it was commanded by Professor Niu, and the big stones were used to rely on each other to form a support to resist the collapsed stones on the cave, saying that it was guaranteed that it would not collapse again. ”

"Then you all go in, and then the dust will be very heavy, and everyone will crouch in the corner, close their eyes, and cover their mouths and noses with strips of cloth dipped in water. ”

"You're going to start?" Captain Zhang still didn't understand.

"Yes. Li Xun said, "Captain Lin, give me your bow." ”

Lin Qingshan was stunned, and hurriedly took out the folded compound bow from his backpack, gave all the arrows in his leather pocket to Li Xun, and then turned around and ran in quickly.

Captain Zhang said, "How do you get it?"

Before he finished speaking, he saw Li Xun wrap the leg-like bomb around the shaft of the arrow, and after wrapping it with a wire a few times, he wrapped the button with a pile of adhesive tape and fixed it on the arrow.

Captain Zhang's eyes widened: "What are you kidding, I can tell you in advance, this shot will be gone, the only bomb will be gone, don't expect their howitzer, that howitzer can't be used as a bomb." ”

Li Xun just asked, "Are you sure that as long as you press it, it will definitely explode?"

"Of course you're sure, but are you sure you can detonate it?" said Captain Zhang worriedly, he already understood what Li Xun meant.

Tie the bomb to the arrow and shoot it into the crack in the top wall. Shoot another arrow at the button.

But the more I think about it, the more unreliable it becomes, how big is that button? The size of a soybean.

How far is it? It's tens of meters high.

And there is no light above at all, the only light is the kerosene lamp on the wall near Dragon City, in such dim conditions, let alone seeing this button from a distance of dozens of meters.

It's only ten meters away, and even the arrow can't be seen.

It was completely pitch black above, like a black hole, and the gods didn't know where the arrow would shoot after it flew out.

Li Xun didn't speak, dipped his index finger in his own saliva, and then evenly smeared it on the button.

After a moment, he suddenly lifted his breath and wound the arrow with the bomb tied to it, aiming it at a seventy-degree angle.

As soon as the arm span opened, the ninety-pound compound bow was suddenly pulled for a full moon, as if it were a toy at all.

Then, Li Xun let go suddenly, only to hear a 'bang', and the arrow with the bomb flew out suddenly.

After a while, I heard a soft 'ding' sound from above, and there was no movement.

Li Xun waited quietly for a while, then turned his head and smiled: "It seems that I am lucky, I got stuck and didn't fall off." ”

Captain Zhang didn't speak, silently took a step back, and looked at Li Xun in disbelief.

However, Li Xun used two fingers to break the sharp arrow of the other arrow, forming a flat, non-lethal arrow.

Then, it's time to shoot again. (To be continued.) )
