Li Bing squatted on the ground and asked, "Do you want to wait for her?" ”

Lao Wu bent his waist and said, "Don't wait, she knows the place, and she will follow in a while." ”

The four of them continued to walk in brocade clothes. They climbed over the highest ridge and descended a gentle slope to the altar.

Yu Xiaolong put down his backpack and took out a silver rectangular box and opened it, which looked like a laptop inlaid inside, with a screen on the lid of the box, no mouse and no keyboard, but a joystick and two rows of buttons.

Yu Xiaolong pressed the start button, and a rotary-wing unmanned helicopter rose into the sky in the distance and flew towards them.

The drone turns on the camera, and the screen is divided into four screens, showing the infrared scene around the drone.

In a short time, the drone had silently flown over their heads, this drone was already in the Big Mac class, and the fuselage was falling with a rope and a package.

Yu Xiaolong took off the package and opened it, and a small drilling machine, also known as the ground auger, appeared in front of him.

Li Bing said: "Is this thing loud? Will it alarm the security guards in the mausoleum? ”

Yu Xiaolong said: "I have already investigated last time I came, there is a shortage of security guards here at night, patrolling once an hour, and besides, this is a cemetery, who is not afraid to walk around at night?" To say that it is a patrol is to hurriedly sweep around the cemetery, not so carefully. The drone had already photographed the security guards walking back, so we still have an hour, which is enough. ”

Lao Wu said: "Don't take it lightly, raise the drone and focus on monitoring the duty room." ”

The drone hovered in the air, and Yu Xiaolong set up the drill and placed it in the position that had been drawn with chalk.

With a dull rumbling sound, the four blades in front of the Earth Auger turned in unison and drilled into the ground. The speed of the machine was amazing, and it dug half a meter deep in a short time.

Lao Wu was addicted to smoking again, squatted next to him and smoked a few puffs, he said: "It's still high-tech, I think we used to dig out with a shovel and shovel, and it took a week to steal a hole, but now it's really convenient." ”

Yu Xiaolong said: "How many meters do you estimate you have to drill deep?" ”

Lao Wu said: "Three meters is about the same. ”

A figure appeared in the distance, coming towards them, several people were alert, the gun in Yu Xiaolong's hand was loaded, Li Bing whispered: "Sun Xiaoxiang? ”

The man did not answer, but went around behind a hill. Li Bing shouted twice, but no one answered.

Li Bing said: "I didn't dare to shout loudly just now, will she get lost and can't find here?" ”

Lao Wu said: "How is it possible? People who are often active underground have not as developed facial features as you can imagine, is that person Sun Xiaoxiang? ”

Li Bing said: "It is supposed that she should have come at this time, but the clouds blocked the moon, and the light was so dim that she couldn't see clearly." ”

Lao Wu said: "Bring all the night vision devices!" ”

Xiaoqing took out the night vision goggles, and several people covered their faces.

The drilling machine has been drilled down more than a meter deep, Sun Xiaoxiang has not appeared yet, Li Bing is a little anxious, took out his mobile phone to call her, but the mobile phone shows no signal.

He said, "No, there is still a signal here when I came back from last time." ”

Lao Wu obviously felt that the situation was not good, and took out a gun, and the artifact in his crotch was already restless.

Lao Wu said: "My artifact dagger has already sensed the murderous aura, just now that person doesn't know where to hide, Sun Xiaoxiang is in danger!" ”

Yu Xiaolong raised the drone high in the air, with all the cameras facing down, overlooking the entire mausoleum area. Dozens of red dots appeared on the screen around them.

Each red dot represents a person who emits heat and is surrounded by clusters.

Yu Xiaolong pressed a red button, and the drone opened eight more covers, and eight shooting holes stretched out. Each aimed at the 8 red dots closest to them.

Li Bing's breathing became rapid, he held the gun and said, "Damn, could it be that Lu Xintai is back again?" I also brought so many people, do you want to fight with them! ”

Lao Wu said: "Don't panic, these red dots have not moved. Wait, wait until we get through it, let's hide. ”

Before the words fell, there was a swish in the distance, and a bright light flew from the ground into the air, dragging a long light and shadow, heading straight for the drone.

Li Bing said: "Sky Monkey? ”

Yu Xiaolong said: "This is a missile!" ”

He operated the joystick, and the drone dodged left and right, but the missile was always in hot pursuit, he adjusted the shooting hole, and bombarded the missile violently, and finally there was a bang, and the missile exploded in the air!

The drone adjusted the angle, Yu Xiaolong pressed the automatic button, and the drone immediately flew to the red dot dense area, and there was a fierce strafing.

Three more swishing sounds, three missiles were launched from three different directions, two missiles came straight at the drone, and the other flew to the duty room in the distance.

This time the drone could no longer dodge, struggled for a while, and was finally shot down.

The flames of the explosion made the sky instantly brighter than day, and the duty room was already a sea of fire.

The drill rig has been adjusted to extreme mode, the cutter head is spinning rapidly, and the machine is making a screeching sound.

Eventually, a lump of dirt crashed down, the hole was drilled, and the drill machine fell into the burial chamber, emitting a puff of black smoke that smelled of burning.

The enemy in the distance was rapidly approaching, Yu Xiaolong fixed the rope and said, "You go down first, and I will break it later!" Xiaoqing, you first! ”

The fierce battle in the air just now had made Xiaoqing's face pale with fright, and she was stunned in a panic.

Yu Xiaolong said: "Hurry up, what are you waiting for!" ”

At this time, Xiaoqing said a very stupid thing, she said: "If you don't go down, I won't go down, I'll accompany you!" ”

Lao Wu suddenly said angrily: "It's stupid to still talk about children's private affairs!" As he spoke, he picked up Xiaoqing, pulled up the rope and jumped down.

Li Bing also jumped off afterwards, Yu Xiaolong picked up the machine gun and fired at the crowd that had rushed over, and someone was immediately shot and fell to the ground.

Gunfire rang out from all sides, and the other side returned fire fiercely.

Yu Xiaolong hid behind the broken monument of the six horses of Zhaoling, the other party obviously did not have night vision equipment, and when he shot indiscriminately, the broken monument was broken into pieces flying sideways.

Someone made a gesture of raising his hand to throw, Yu Xiaolong immediately rolled over, flashed out, jumped into the hole, and with a bang, the grenade blew up the broken monument to pieces.

The place where Yu Xiaolong fell was the very center of the tomb, this tomb was not very big, and Lao Wu and the others were already hiding in the corner of the wall and aiming at the entrance of the cave.

Dozens of heavily armed men in black have surrounded the entrance to the cave.

The leader, dressed in a black security uniform with an unknown epaulettes, turned on his flashlight and shone it into the hole, and a bullet flew out of his nose. As soon as he looked up, his hat had been knocked off. Lao Wu leaned against the wall and said, "Shi Zhenshan! I didn't expect to meet you here, I haven't seen you for many days, so don't be harmed. ”

The leader was the head of the security guard who deliberately let them into the tunnels of the city wall that day.

Someone wanted to throw a grenade into the hole, but Shi Zhenshan stopped him and said, "The things inside are precious, don't dare to blow them up." ”

He raised his hand, and the two people behind him carried over two steel cylinders, which were printed with the logo of a skeleton.

One person put a skin tube on the gas cylinder, and the skin tube reached into the hole, opened the valve, and a stream of gray-white gas sprayed in. Lao Wu and the others immediately put on gas masks, which were originally prepared to protect against the mercury vapor in the tomb, and they came in handy at this time.

When the tomb was already full of poisonous gas, Lao Wu looked at his watch and motioned for people to go down.
