Chapter 885 Tana River

Bifang led Halley along the river, trying to find a shallow beach or land to cross, but after walking for more than half an hour, they did not find a suitable place to cross the river.

After walking for a long time, Halley felt a little tired and lay on the ground, refusing to move another step.

Bifang saw that there was nothing he could do.

Facing the river full of crocodiles in front of him, he could only find another way to cross it.

"Crack."

A tree trunk as thick as an arm was broken off. When the length was right, Bifang tied it with other trees in parallel with a tree rope to form a row.

From the shape of the wood, it was obviously a simple raft.

"We can't find a suitable place to cross the river directly. If we want to continue to go north, we can only build a raft to cross the river."

If it were any other river, Bifang would choose to swim across with Halley.

But this is Africa, and the river is full of ferocious Nile crocodiles.

"In many wildlife documentaries, we often see Nile crocodiles lurking in rivers and hunting, but in fact they have only a few opportunities to eat animals in a year."

"For the vast majority of Nile crocodiles, they only have two big meals a year, both of which are related to the East African animal migration."

"The animals eat once when they go and once when they come back. These are the only two meals most Nile crocodiles have."

[No way, just two meals? ]

[This is outrageous, two meals a year, won't they starve to death? 】

【I was so scared that I quickly ate two mouthfuls of rice】

"They won't starve to death. Nile crocodiles have a strong ability to endure hunger. They can go without food for more than half a year after hunting a zebra and having a full meal."

"There is little rain in the dry season in Africa. In order to avoid such unfavorable living conditions, Nile crocodiles often use their mouths and feet to dig caves on the river bank and hide underground to hibernate until the next rainy season."

"Sometimes they can dig 12 meters underground, which is the deepest depth that animals can dig with their bare hands."

"So I definitely don't dare to swim across the river. Before the large-scale migration of animals, everyone is hungry and will not let go of any large living creature."

【Nile crocodile: Brothers, come to life】

【Plop, splash, crocodile: What the hell is going on? 】

"You know, Nile crocodiles attack people 275 to 745 times a year, of which more than 63% are fatal. The average size of Nile crocodiles that cause non-fatal attacks is about 3 meters, and the average size of Nile crocodiles that cause fatal attacks is 3.5 meters. They are considered to be the largest wild animals in Africa that cause the most fatal attacks on people."

"In contrast, from 1990 to 2006, the number of fatal attacks on humans by lions in Africa was estimated to be one-eighth of that by Nile crocodiles."

[Death spin! ]

[If you are bitten by a crocodile, you will be dismembered directly.]

[This is too scary.]

[Terrible.]

Bifang bit the end of the rope and stretched it straight, tying the wood tightly with his fingers.

There are many dead trees on the grassland, which are good materials for building rafts.

"To make a raft, you can use bamboo or small trees uprooted by the roots. Such materials are strong and will not rot. You can also use the top of a dead tree trunk. It has great buoyancy and requires less material for the same buoyancy."

"If you have an oil drum or an object that can float, it will be even better. They can be used to support the raft."

"If you really can't find wood, a piece of waterproof canvas or other waterproof materials can also be used to make a light boat for people."

The afternoon sun is a bit big. It is close to three o'clock after two o'clock. It is still the hottest time of the sun. Under the continuous work, sweat begins to appear on Bifang's forehead.

Sweat beads slide down the temples and fall along the jawbone. Some turbid sweat beads drip on the white dead wood, soaking out a small piece of dark color.

A large number of trees of uniform thickness are lined up and tied tightly with bark ropes as thick as little fingers.

Now Bifang's skill in making ropes with fiber is becoming more and more sophisticated. He can make a one-meter-long, little-finger-thick, strong enough bark rope in one minute, which greatly speeds up the completion of the entire raft.

"The water system of the river in front of us is still relatively complicated. From the perspective of geography and orientation, I guess it should be the Tana River system, or one of its branches."

While making the raft, Bifang can also do two things at the same time, introducing the information of the river in front of the audience.

The width of the river in front of him is more than fifty, and the water flow is not turbulent. If you don't pay attention, you may even think that it has stopped flowing. There are a few scattered pieces of land in the middle of the river, covered with reeds and grass as high as a person.

Looking down from the sky, the drone is completely a swamp.

Such a width, plus the unknown length.

A river of this size can never be an unknown "river".

As a professional survivor, you should know the famous rivers in the world. As the world's number one survival expert, Bifang is even more so.

"There are many large rivers in Africa, but in Kenya, there are eight rivers that can reach the scale in front of us. However, according to the current location, there are only two, namely the Tana River and the Galana River."

"The source of these two rivers is in the Great Rift Valley of East Africa, rushing all the way down and finally merging into the Indian Ocean."

"The source is the same, the destination is the same, so if you don't know your specific location, it is difficult to distinguish the two rivers."

"But we are now in the east of Kenya, south of the Nyika Plateau. Due to the height difference, the river speed is very turbulent. The Galana River is like this. The Tana River should be like this, but it is larger and has a larger flow, so Kenya built a dam above it to generate electricity."

"Although it is the rainy season now, it is far from the time for the dam to release water. With the buffer of the dam, the flow of the Tana River appears to be much smoother and the water quality is relatively clearer. Therefore, we can distinguish it from these two points and determine that it is the Tana River in front of us."

The impact of the dam on the flow rate of the river is very complicated, and Bifang just said it simply.

However, there is a truth that is understood, that is, energy will not appear out of thin air. Hydropower stations use the potential energy of water flow to generate electricity, and the flow rate is naturally slowed down.

[I don't know what to say, it's outrageous, but since it's Fang Shen, just play normally]

[Play steadily, keep it up]

[Call Fang Shen]

[Analysis is as fierce as a tiger, and the audience is stupid]

[I understand, but I don't understand it completely]

[Single 6]

It took about two hours to build a raft about three meters long and two meters wide.

"When riding a raft, all equipment must be securely tied to the raft or to the safety rope."

"Make sure there is nothing dragging on the edge of the raft, otherwise it may damage the raft in the shallows."

"At the same time, we need to tie a few free ropes on the raft. When we are in the river, we need to tie the ropes to our bodies to secure ourselves and act as safety ropes."

"The safety rope should be long enough to allow everyone to move freely, but not too long to avoid being dragged in the water."

"When rapidly crossing turbulent water and large drop rapids, it is best to untie the safety rope. In this way, if the raft loses control, everyone can swim to the river bank."

Bifang tied the rope around his waist, found a safe point, and slowly pushed the raft into the river.
