Under the leadership of the Uighur birds, they walked through the dense fern forest.


    This fern forest is the territory of black giant dragons. In addition to a black dinosaur as huge as Mount Tai, there are also nests of giant dinosaur eggs on the ground.


    The eggs were stacked in round, bungalow sized nests. The nests were made of wet mud, and the edges were as high as people''s, just like a rudimentary bird''s nest.


    There are a lot of newly broken small black dragons pacing around the nest.


    They are about 1.6 meters tall. Their skin is like a mass of ash juice. They are tender and not rough at all. Their eyes are very dull. They look silly. They make a tender cry at them.


    At this time, Jiaojiao suddenly opened the mouth of the python, caught one of the small dinosaurs in its mouth like lightning and swallowed it.


    "Jiaojiao!"


    Ye Xi was startled.


    He quickly looked up at the black dragon''s reaction, but found that these careless parents were busy swallowing fern leaves, did not notice here.


    Ye Xi and others breathed a sigh of relief.


    However, although the black dragons did not respond, ye Xi did not dare to let Jiaojiao do this again. After criticizing Jiaojiao, he immediately ordered the team to take good care of their mounts and never eat these tender and silly little dinosaurs.


    The river was not far away from them. After walking about 200 meters through the fern forest, they could see a large expanse of brown sand beach, as well as a slow flowing clear river.


    On the Bank of the river, a large group of huge black dragons were drinking water.


    On the broad sand beach, groups of newly broken small black giant dragons are chasing each other. In addition, there are carnivorous dinosaurs waiting for opportunities to hunt little black giant dragons, and all kinds of mammals who come to the riverbank to drink water. It seems very lively.


    They were very surprised to see the river, so they quickened their pace and walked to the river.


    At this time, the black dragons in the river turned their long necks and turned back one after another.


    Bang!


    Bang! Bang!


    As tall as Mount Tai, the black dragons walked with thunder like steps, one by one slowly to the direction of the fern forest. When their huge limbs step on the beach, the beach immediately formed a huge area of holes.


    A lot of little black dragons running around accidentally fell into these holes, leaving only half of their bodies exposed.


    They screamed and struggled, but they couldn''t get out of the bunker. They were swallowed up in the sand and could not be seen again. But the adult black dragon seems not to notice, continue to walk slowly towards the fern forest.


    Quicksand pit!


    Ye Xi was awe stricken.


    "Be careful, don''t fall into these bunkers!"


    "Remember to avoid these bunkers!"


    The black dragons came face to face, as if the mountains rolled over, and the people hurriedly scattered to avoid their steps. Because of Ye Xi''s instructions, people also avoided the huge pits in the sand mixed with water on the beach.


    "Ah


    Then a scream came from behind the crowd.


    When ye Xi turned back, he saw that three people fell into the quicksand pit by accident, and all of them were trapped in the mixture of water and sand below their knees.


    Bang!


    Bang! Bang!


    The crowd was trapped in the middle of the black dragons, and huge objects passed through the crowd, shaking the ground around them.


    Ye Xi drank: "keep going to the river!"


    After that, he went against the crowd and turned back to the quicksand pit to avoid opening several black dragons.


    The black dragon''s footprints are very large, and the quicksand pit is seven or eight square meters, which is the size of a room. Two men and a woman were trapped, and the deepest man had been swallowed up to his thighs by quicksand.


    Next to the footprints, their relatives and friends are holding their hands tightly, trying to pull them out, but they can''t pull them out.


    Ye Xi looked at the people in the pit and was surprised to find that one of them was Alsophila spinulosa.


    "Don''t be afraid of Alsophila spinulosa. I will surely rescue you!"


    A strong stone tribe warrior kneels next to the sand pit, holding the Alsophila spinulosa''s hands tightly, his arms bulging and trying to pull her out of the bunker.


    Alsophila spinulosa''s face was red and dragged by people, but even if both arms were dislocated, they did not get out of the quicksand pit at all.


    Her arms hurt so much that she broke down and cried, "no! Brother, my arm hurts too much! It''s like it''s going to be torn


    The other two were trapped in the pit. One was a young soldier, and the other was a thin boy. They struggled hard before. As a result, the more they moved, the more they sank, and soon they sank to their thighs. And now there are two soldiers pulling them respectively, but it''s no use at all, not even a trace of it.


    They were more and more panicked.


    Just now, in order to avoid the steps of a black dragon, some people accidentally fell into it when they retreated. They thought it was just a shallow sand pit, but they could not even pull it out. It looks like such a shallow sand pit!Ye Xi immediately said, "don''t move!"


    If they fall into their chest in a quicksand pit, they will find that they can''t even breathe, and then suffocate to death.


    In his previous life, he had seen people doing experiments on TV.


    The experimenters put a doll''s foot into the man-made quicksand pit, but they couldn''t pull it out of the hole even with the force of 30 times the doll''s weight. When the doll finally pulled out, the doll even broke from the waist.


    In the experiment, a man put his leg into a quicksand pit, and as a result, even the gantry crane could not lift the man out. If you pull a person out with a giant force, it is very likely that the muscle will be torn and the leg will be broken.


    Those who have not seen quicksand pit can never imagine that its suction will be terrible to this extent.


    The three people in the quicksand pit and the five people outside the sand pit saw Ye Xi coming. They were as excited as if they saw the Savior.


    "I have seen Xiwu!"


    "Lord Xiwu, please help us!"


    "We don''t know why we can''t get out of this bunker!"


    "I can''t feel my feet!"


    Alsophila spinulosa did not say a word, but looked up at Ye Xi with red eyes and a cry for help.


    Because of her bad migration life, her hair was as dry as weeds, her skin became dark and rough, and she could not find her former beauty, but her eyes were still smart.


    Ye Xi had already forgotten her, but this glance immediately reminded him of the red grass Festival a few years ago. The girl was so enthusiastic that he couldn''t resist.


    "Don''t be afraid. It''s OK." Ye Xi comforted with warm voice.


    The voice of the young man was clear and clear, but it was very reassuring. The three people in the sand pit settled down and were no longer afraid.


    Alsophila took a deep breath and looked at Ye Xi''s tall and straight figure, tears suddenly ran down.


    Ye Xi squatted down and twisted a handful of sand, and found that the sand and gravel here are very delicate.


    He sighed. The finer the gravel is, the more terrifying the suction caused by the quicksand pit. Countless creatures may have been buried under this calm beach.


    The experiment was eventually rescued from the quicksand pit by a blower and a pipe.


    The reason why quicksand has strong suction is that it forms a vacuum sealing structure around the leg. They inject gas into the quicksand pit constantly, which destroys the structure and successfully saves people.


    But obviously there is no blower here, so what to do?
