There are terrible animals in the rainforest, boa constrictors, the largest snakes in the world. When hunting, boa constrictors usually wrap their prey with their huge bodies and strangle them alive. Finally, it swallowed the whole dead prey and digested it slowly. There is a piranha in the Amazon River. It will eat a live cow in 10 minutes, leaving only a pile of white bones and terrible electric eels, which can instantly emit 200 volts of high voltage electricity. Man-eating vines have long vines, which will roll people up and secrete corrosive mucus to corrode digestive animals. Some will entangle their prey, attract black butterflies and make their prey bloody. I didn't expect that there are butterflies that eat animals in the world. Some vines catch people and give people flowers. Every 7 or 8 people are full, a man-eating flower will grow. There is also a mosquito in the rainforest, which is bloodthirsty and will expel larvae into people's bodies, producing thousands of insects. Finally, insects will swim in the human body and finally flow into the eyes, causing blindness. Some mosquitoes carry malaria virus.

Karakorum Mountain has its own unique climatic conditions. Influenced by the monsoon from the Indian Ocean, the south slope is warm and humid, with many trees. On the other hand, the north slope is extremely dry. Due to the lack of water and cold, the barren scene of Gobi is formed here, as Younghusband recorded in his diary: "I can't believe my eyes, as God is my witness, it's like witchcraft of wizards. The lush and vibrant scene makes it difficult for me to associate it with the desolate scene behind me, but in fact, they are two sides of the same mountain.

There is a strange hillside in Utah, USA, called "Gravity Mountain". There is a steep slope with a straight line distance of about 500 meters. It is also a world-famous strange slope. When you drive here, you will find that the car is slowly climbing the hillside, as if being pulled by an invisible force.
