"Ah Zheng, so fast!" As soon as they met, Huang Yonghui spoke.

Tang Zheng nodded and looked around, this was a hilly area. It's not the kind of deep mountains and old forests. The height of the mountain is also more than 1,000 meters. Moreover, there are not many big mountains, and in the middle, two mountains several hundred meters high are clustered with a mountain more than a thousand meters high. And then all around is the hills. In this area, a police cordon has been set up. Around the place where the sinkhole was found, within a range of one kilometer, armed police officers were stationed guards.

A striking warning sign was erected next to it - 'There is a sinkhole ahead, no entry.' ’

Next to Huang Yonghui, a man who looked like a local leading cadre also greeted him with a smile: "Professor Tang, hello, I am from the local government. Residents within a three-mile radius have been evacuated......"

Tang Zheng nodded and interrupted directly: "Hello, this is my work card." From now on. The government and the local police were all evacuated, and we took over the place. ”

After speaking, Tang Zheng gestured, and Ye Jun next to him also took out a document, and the red seal of the military department was eye-catching. Tang Zheng is not in the mood to talk nonsense with local cadres now. The life and death of the leopard is unknown, where is there still the mood to listen to them report this mess.

Looking at the red-headed document, he didn't read the words on it in detail, but there was one thing that he could see clearly, the exploration of the sinkhole will be accepted by the Hidden Dragon Brigade of the Military Department, and the captain Tang Zheng will be fully responsible, and the local governments, local garrisons, and armed police forces will go all out to cooperate.

As soon as he saw this, the cadre immediately nodded and said, "Professor Tang, please rest assured." I immediately set about arranging it. Do the perimeter guards need to be removed? ”

Tang Zheng groaned. Said: "The vigilance on the periphery is still maintained. Avoid the occurrence of secondary disasters, trouble you. ”

Under the leadership of Huang Yonghui. The group crossed a mountain road of about 300 meters and soon came to the side of the sinkhole. On the highest hill of this kind. The entire top of the mountain has been completely flattened, and the top of the mountain has completely collapsed.

There were a lot of trees in a mess, some of them showed their roots, and the whole tree fell. Some are already oblique.

In the middle, a huge circular crater with a diameter of fifty meters is in view. Standing on the edge of the sinkhole, looking at the lower area, it was pitch black. Bottomless.

Around the sinkhole, several tents were erected. The four corners of the tent, holding ropes. The length of the ropes is about a kilometer. Far away from other trees. This arrangement ensures the safety of the tent to the greatest extent.

All these things that Leopard has added are professional-level things. It won't fall even if it's suspended in the air. In this case, even if the position of the tent is now collapsing again. Under the traction of ropes, the safety of all personnel can also be guaranteed.

Next to the sinkhole, a small steel wire of high strength can be seen. This is specially processed. It's just a three-millimeter-thick steel wire. But it can pull up something that weighs nearly three tons.

"Brother Huang, tell me about the situation in detail." After Tang Zheng briefly checked the terrain features, he said to Huang Yonghui beside him.

Here, the members of the Hidden Dragon Brigade are already starting to set up tents and other things. Some of them have already been divided. Some are measuring and making three-dimensional images of the current area. Some of the people had already walked to the side of the sinkhole. Several electronic devices were taken out of the bag and thrown into the sinkhole. A gunshot rang out. A flare had been driven into the sinkhole. The high-speed camera began to shoot continuously with a click.

Huang Yonghui nodded, "We decided to come on an expedition a week ago. After arriving here, after preliminary exploration and preparation. Three days ago, the leopard and two other brothers went down the sinkhole. As we had agreed, they prepared food and water for three days. Three days later. They pull the wires, and we lift them up. But. Three days passed, and there was not a single word from them. One of the steel wires. We tried tugging. When I pulled it up, I found that the wire had been broken. The other two steel wires did not move at all, and they could not be pulled at all. That's when I called you. ”

After waiting for about half an hour. Ma Jingtian walked over and said slowly: "Ah Zheng." A preliminary probe was made, judging by the feedback from the laser rangefinder. The preliminary estimate of the sinkhole should be more than three thousand meters deep. In this case, judging from the elevation of the peak, it is only more than 1,630 meters. Other words. The sinkhole is at least a distance of more than 1,000 meters deep into the ground. Distances of such depth. It's hard to say what kind of state it is underneath and what kind of situation it is. Hypoxia, I guess yes. ”

Next, a series of things such as three-dimensional maps, mountain structure maps, geological maps, and so on have been taken over for this area.

Ye Jun, Zhang Chao, Li Ming and Zheng Ying were all sitting in the tent. After some analysis, Ye Jun said slowly: "Ah Zheng, without further ado, time is life." In my opinion, we still have to hurry up. The earlier you are exposed to the actual situation, the earlier you can identify the problem. ”

Tang Zheng nodded, he was the one who was most anxious about the leopard's accident. Brotherhood, blood ties, this is something that nothing can erase.

But Tang Zheng still said slowly: "Brother Jun, you go and contact the local government." Change equipment. We need a one-centimetre wire rope. The length of ten sets and one set should reach at least 10,000 meters. In addition, we need two sets of wires. 100,000 meters, a lamp holder in series every ten meters. Have the appropriate number of light bulbs ready. Help us get in touch with the power supply. And ensure the supply of power supply. I hope to be able to solve it in two hours. ”

Tang Zheng's words, this already expressed Tang Zheng's attitude, he was ready to investigate openly. When the lights are connected, the following conditions can be detected to the greatest extent. Be the first to react.

Ye Jun nodded and said, "Okay." I immediately went to get in touch. ”

With the big red seal on it. All the work is unconditional and full cooperation, less than two hours. The stuff has already been delivered.

At this time, Tang Zheng and the others did not have the slightest nonsense. It's just fixed. Ten sets of steel cables. They hung down from ten different directions. The distance between each other is about 10 meters, stretching for 100 meters. The two sets of wires are held vertically by the members of the fourth and seventh groups in the middle. At each distance, a set of light bulbs is installed on it.

Tang Zheng and Zheng Ying are in the fifth and sixth groups respectively. Both were the first to go down.

With the strength of the two of them, the speed of descent is fast, and it is a distance of nearly 100 meters. Then use the rappelling device to jam the speed. Soon, in less than two minutes, Tang Zheng and Zheng Ying had already descended to the bottom of the sinkhole. Down-to-earth on the ground.

It was less than five minutes after Tang Zheng and Zheng Ying came down. The other eight groups of players also came down one after another. The lights followed.

After looking around, Tang Zheng and Zheng Ying glanced at each other, both frightened by the scenery in front of them. I thought that the diameter below the ground was only fifty meters. But now, that's not the case. The whole sinkhole is in the shape of a gourd, and the area sunken above is just a small gourd mouth. Standing below, you know how big the area is.

The dirt, trees, and sand that had fallen were now just a small mound. It is surrounded by an area of more than 100,000 square meters. It's a huge space of two hundred meters by five hundred meters. It's like an underground shijie.

The rest of the team came down one after another. Tang Zheng looked around and said in a deep voice: "Brother Jun, contact the above, and let Brother Huang and them help us lower the equipment and tents." Also, notify the local authorities and help us with the logistics. ”

"Brother Jun, you arrange four team members, four squadrons of Wind Forest Volcano. Each team leaves one person. Keep a Maritime Satellite phone and keep in touch with it at all times, or do it in groups of four. The four squadron leaders were also with me and Zheng Ying. The detachment conducted a carpet search. ”

Tang Zheng's words, attitude and meaning are all understood. Tang Zheng is preparing to fight the war nearby. Directly set up the rear base under this.

After Tang Zheng's instructions, the team was quickly formed. Basically, it's all the same, each of the four squadrons comes out with one person and the others are free to combine.

Tang Zheng is in charge of the front side. Look cautiously along the way. Over time, after two hours, the area had been completely searched.

At this time, Zheng Ying suddenly pulled Tang Zheng's clothes, pointed to the front, and said in a deep voice: "Ah Zheng, look." ”

Look in the direction of Zheng Ying's finger. Ye Jun, Ma Jingtian, Zhang Chao and Li Ming, the four people from the ancient martial arts world, all looked straight ahead in amazement.

Tang Zheng looked over. At this moment, Tang Zheng was also shocked. Right at the front of their position. A huge bronze gate was already in front of them.

The height of the gate is beyond the realm of recognition. It is a full 100 meters high. at least forty meters wide. There are no words to describe this. On either side of the gate, two huge bronze heads. Lifelike. It's incredibly vivid. The avatar is exactly the same as the avatar of Sanxingdui culture.

Exaggerated drum meshes, protruding at least ten meters away. There is a vertical eye in the middle, and the ears are long. This is simply a giant bronze statue in the Sanxingdui Museum.

Seeing this, Zheng Ying also said slowly: "How is this made?" Can man forge such a magnificent gate? Can it be turned on? (To be continued......)
