"Mr. Wuge, what can I do for you?"

    After connecting the phone, Liu Qing asked in surprise.

    Just listen to the old Wuge said on the phone: "well, recently there have been a number of mysterious tiankengs all over the world, and we also have a Tiankeng in Huaxia."

    "It''s not clear on the phone. Can you come now? We need your help."

    Five cabinet old just mentioned a, and then to the point would like to invite Liu Qing to a chat.

    Liu Qing frowned slightly, thought about it and said, "OK, I''ll go now. Where are you?"

    "I''m in Qingshan ancient town..."

    Mr. Wu gave an address.

    The two ended the call.

    "Tiankeng?"

    After hanging up, Liu Qing frowned slightly and murmured to himself. He was curious about the mysterious Tiankeng that the five cabinet elders said.

    He said that there were a number of mysterious sinkholes all over the world at the same time, which was very unusual.

    When he heard that, he naturally wanted to have a look.

    "Qinglin, Xiaobai and huoque, you three should practice well here. Don''t make trouble and hurt people."

    Before he left, Liu Qing handed over three spirit beasts and left Wudang Mountain without saying hello to Taoist priest Qingxu.

    ........

    On the other side, the secret base.

    A group of researchers are busy nervously.

    The people here are dignified and tense.

    Mr. Wuge stood on a satellite screen and silently looked at the above monitoring images and information.

    "Ge Lao, according to the latest satellite photos, a total of 10 tiankengs have been found in the world, each of which is extremely huge."

    "There are three tiankengs in Europe, three in North America, three in Africa, and one in China. There are altogether ten tiankengs."

    At this time, a gray haired old man came with a report.

    Pointing to the satellite image in front of him, he said: "Mr. Ge, please take a closer look. The satellite image shows that ten tiankengs have been shot all over the world at the same time."

    "A few of them were in no man''s land, causing no casualties."

    Ten unidentified huge black spots appear on the global satellite image territory, which are all unexplained Tiankeng.

    The ground collapses, exposing a deep pit, which is called Tiankeng.

    The smallest one is 300 meters in diameter, and the largest one is 10 kilometers in diameter. It''s very dark.

    "Is the situation of Tiankeng known?"

    Asked the old man with a dignified look.

    The old man said: "UAV has been sent to detect, and the result is the same as the previous several times. Once flying over Tiankeng, the UAV is directly disturbed by unknown magnetic field, and the UAV falls and damages on the spot."

    "There is an unidentified strong magnetic field around the Tiankeng, the energy is unstable, and any instrument will fail immediately when it approaches."

    This statement made everyone present feel the seriousness of the matter.

    "What about other tiankengs outside China?" The five cabinet elders spoke again.

    Immediately, the researcher released other satellite images and data.

    "There are nine tiankengs in other countries, several of them in some towns and villages, causing great losses and a large number of casualties."

    "And the data are basically the same, there is an unknown magnetic field, any instrument failure."

    "One of the biggest Tiankeng is in China, and it is also a disaster causing the most casualties, directly collapsing and engulfing most of a small town."

    "More than half of the whole town collapsed. The casualties have not been counted yet. Someone has been sent to block and rescue it."

    The old man said solemnly, the news solidified the atmosphere.

    Half of the town has collapsed, and you can imagine how terrible the situation is there.

    According to the pictures taken by the satellite, a small town in Huaxia collapsed directly in the center, forming a huge sinkhole with a length of 10 kilometers.

    Ten kilometers of Tiankeng almost swallowed up the whole town.

    No one who fell in knows what''s going on now. Emergency rescue is under way, and it''s still unknown whether it can be found.

    After all, the sinkhole is deep and has unknown magnetic interference, so no electronic device can enter the sinkhole.

    The only way is to organize personnel to explore, then rescue can be launched.

    "It''s urgent to find out the secret of tomorrow''s pit as soon as possible. At present, major organizations around the world are working with geologists and scientists from all over the world to discuss countermeasures urgently."

    "At all costs, be sure to check the secret of tomorrow''s pit and find all the missing people in the town."

    "Also, I ordered that the area where the Tiankeng is located be sealed off, and that no irrelevant personnel be allowed to approach it."

    Mr. Wu delivered one order after another.

    Tiankeng incident caused the whole world to boil and panic, and caused a stir to this sudden Tiankeng incident.

    When Tiankeng appeared in the world, it caused hundreds of thousands of casualties and disappearances, causing a sensation all over the world.

    At this moment, the whole world is facing a huge disaster, not only from the world changes brought about by a variety of biological variation, attacks on human beings.

    There are more unidentified events, such as this Tiankeng event.

    No one knows what kind of secret and danger there is in Tiankeng.

    It''s hard to say whether more sinkholes will appear, or even lead to exploration of the earth''s interior and direct collapse of the earth''s surface.

    Human society is facing a huge threat.

    People all over the world began to search for the secrets of Tiankeng, and organized people to enter Tiankeng to explore the situation in Tiankeng.

    Huaxia, as early as the first time Tiankeng appeared, had sent the most elite team to explore the situation.

    After all, half of the town collapsed, and the casualties inside must be searched and rescued.

    ........

    Huaxia, Qingshan ancient town.

    The ancient town, which used to be green mountains and beautiful environment, has become dilapidated, and most of the center of the town has collapsed.

    The original town has formed a 10 kilometer long sinkhole, which is dark and invisible. It has been blocked and the survivors have been rescued.

    The whole town is quiet, only one army is in emergency rescue.

    But the sinkhole is too big to see the bottom. Before, I tried to let the UAV go to explore. Unfortunately, as soon as I flew to the sinkhole, I directly failed and fell.

    In the end, they even used various types of robots to explore, but as soon as they went down, they directly failed and had no effect, which was totally unreasonable.

    In front of Tiankeng, two special teams are gathering here.

    The two teams are Canglong and Zhuque. The two team leaders are longyi and Zhuque, with a total of 22 people. They are all first-class experts and elites.

    Now, two teams are in danger, ready to enter the Tiankeng, search for survivors, explore the secrets and conditions inside the Tiankeng.

    "The Canglong team checks the equipment and prepares to enter the sinkhole."

    In front of the line, long ordered with a serious face.

    "Rosefinch team, pack, check, prepare."

    Rosefinch coldly ordered, ready.

    "Everyone, follow me to the pit of heaven."

    After the inspection, longyi and Zhuque look at each other.

    With an order, Long Yi took the lead and began to walk to the side of Tiankeng.

    Here, several long steel ropes have been set up, and dense steel nails have been fixed beside the Tiankeng.

    All special operations personnel will go down the wire rope from here and enter the sinkhole to explore the situation.

    As one special combat team member after another slides down the safety wire rope, more than 20 people and two special combat teams slide into this mysterious and unknown pit one by one.

    Outside, a legion stationed is nervously guarding, ready to fight at any time.

    Everyone has a dignified look and a sense of urgency in their hearts.

    "Monitor the drop of personnel at any time."

    Outside, inside the headquarters, the five cabinet elders came in person to direct the deployment and planning here.

    All the people are in a tight position, waiting nervously.

    As the number of special operations personnel continues to decline.

    One hundred meters, two hundred meters, three hundred meters, four hundred meters and five hundred meters are still falling. Everyone''s heart is raised.

    Time goes by.

    "A thousand meters."

    Someone dignified said.

    The special combat team has gone down a thousand meters, but it''s not in the end, and it''s still falling.

    This situation cast a shadow on everyone, heavy heart, the scene atmosphere has solidified.

    1200 meters, 1500 meters, 1800 meters, and finally to the depth of 2000 meters.

    Everyone was stunned.

    Tiankeng is more than 2000 meters deep.

    But it''s still within the range of affordability, and soon everyone''s heart comes up again.

    Three thousand meters, four thousand meters, five thousand meters. It''s more than five thousand meters deep.

    Soon, it fell to the depth of 8000 meters, and then it continued to fall. Everyone''s heart was nervous.

    The depth of Tiankeng is more than 8000 meters, but it''s not in the end. Can human survive in such a deep underground?

    "Nine kilometers..."

    "Ten thousand meters..."

    Everyone in the whole headquarters, the breath is frozen.

    "12000 meters..."

    Boom!

    All of a sudden, there was an explosion under the Tiankeng, and all the people in the whole headquarters were in a frenzied state of mind.

    "Report, emergency, we have an unidentified attack..."

    "An unidentified attack... Shasha..."

    There was an urgent sound from the special contact device, and soon the signal was cut off.

    This is a special contact device carried by two special forces. It has strong anti-jamming ability, but now it has been interrupted.

    "It''s over!"

    Everyone''s heart, all of a sudden raised.

    The special forces encountered an unidentified attack 12000 meters below the Tiankeng.

    What is the situation under the Tiankeng and what attack has it encountered?

    "It''s not good, Liu Qing. I hope you can come soon."

    The old man of Wuge''s face sank, and the secret in his heart was not good. He could only wait anxiously.
