Leopard Tooth

Li Jianrui looked at the thick banana tree trunk on the ground, and always felt that something was wrong, because the trunk really didn't look like wood. He was on the mountain before, and he saw people chopping down trees. If you chop it with an axe, it will probably only sap. So much water, can it float in the water?

He grabbed the broad leaves with both hands, dragged the trunk to the river, and then kicked the trunk into the rapids. He saw the banana trunk undulating in the river, flickering, and drifting with the current in the blink of an eye. After several tens of meters, one could see from a distance that the tree trunk did not sink into the water, but it did not float up as Li Jianrui imagined, but most of it did not enter the water, and a small green part was exposed.

"It's still usable, but the buoyancy is limited," Li Jianrui returned to the banana grove, and while cutting trees, he wondered how many tree trunks are needed to make a raft.

He took a closer look. The trunk of the banana tree is about 25 to [-] centimeters in diameter. He doesn't need the raft to be very wide, as long as he can sit on it. It's about one meter wide. In this case , About six or seven banana trees are enough.

Li Jianrui began to select banana trees with a diameter of more than [-] centimeters, and made a large cross mark with a paratrooper knife on the selected trunk, and then began to cut down six banana trees in a row. Li Jianrui felt his shoulder hit It hurts, but the materials for making the raft are ready.

Drag the banana trees to the river one by one, and cut off the leaves and bananas on the crown of the tree with a paratrooper knife. These leaves are like the branches of a banana tree, with thick petioles and wide leaves. One sheet is wide and the length varies from one meter to one and a half meters. In the current, these will affect the movement of the raft. Excessive resistance may even cause the raft to disintegrate in the river. What Li Jianrui is doing now is to trim the trunk and try his best to All the sundries on the trunk were cut off, and the trunk was turned into a bare stick, a big stick.

After the six banana trees were pruned, Li Jianrui took out the parachute from his backpack, slowly spread it out, pressed one side with a tree trunk, and spread it flat on the river beach.

Three hundred square meters of umbrella cloth and a hundred-meter-long umbrella rope can’t be used all at once. He first wrapped a piece of banana wood in the umbrella cloth, pushed it hard, rolled it up, and tied it with the umbrella rope. Tight, so back and forth, six pieces of banana wood were wrapped in the umbrella cloth, and the paracord was inserted into the gap between the banana wood. He used a paratrooper knife to poke a small hole in the umbrella cloth, let the paracord pass through, and tied it into a sailor's knot. The binding methods of "releasing the knot" and "fixing the knot" are used respectively.

As a special soldier, sailor knot is a must. This is no longer the patent of seafarers. Sailor knot can be said to be the crystallization of the wisdom of sailors in hundreds of years of sailing history. It has the advantages of long-term stability, easy knot and easy untie, Li Jianrui At this time, it is handy to use, although when he was learning it at the beginning, he still slandered a few words, thinking that learning this is simply a pain in the ass.

Facts have proved once again: "Opportunities are only reserved for those who are prepared,"

Li Jianrui can imagine that if he used the only bow tie he knew before, the effect would be the same. His own shoelaces are bow knots, and I remember that they would loosen from time to time when walking, let alone in a rushing river.

He will tighten each knot, tie it firmly, pull it with both hands, and test it before continuing the work below. The water flow is 20 meters per second, which is not a joke. That is to say, once it falls into the water, it can only flow downstream Drifting, with no possibility of autonomous action.

If a person wants to act according to his own wishes in the water, there must be a premise that his strength can be greater than the power of the water flow. In other words, he needs to fight with the water flow in the water, and whoever is stronger will win. This is the law of nature. natural law.

When the raft was successfully made, Li Jianrui couldn't hide the joy in his heart. He looked at the river and laughed, while wiping the sweat from his forehead and face with his sleeve. The temperature was getting higher and higher.

Looking up, the sun is already close to the center of the top of the head, noon is approaching, and the time is getting less and less.

Li Jianrui collected all the remaining materials. The umbrella cloth was not used much, and it only took about a quarter to wrap the raft tightly. Only two lengths of rope were used, and the rest were put back into the backpack.

He put the wooden stick that was used to scare the grass and the snake on the raft, carried the backpack and the 95 automatic rifle, and then pushed the raft hard to start the launching ceremony of the new boat.

"Ha, black," the raft seemed to shake.

"Hey, ha," the raft moved, and Li Jianrui felt the movement of the raft, but the moving distance was so small that it could be ignored.

Li Jianrui kicked on the raft, and the banana tree made a muffled sound, "It's paralyzed, it's so heavy, labor and management have forgotten about it,"

One banana log can allow him to use 90.00% of his strength to drag the raft to the river. Now it is six together. According to this calculation, Li Jianrui needs to use 5.00% of his strength to drag the raft. Li Jianrui can't drag it. If he could move, he would not be a human, but an ant, a well-known Hercules.

Now that he had made a mistake, he hurried back to the banana grove, found some small branches and began to cut them down, and specially selected those branches with a diameter of no more than five centimeters. This time he did not want banana trees, but found hard enough wood Trees, fortunately, the paratrooper knife looks ugly, even like a low-quality product, but it is really not covered when used. A four-centimeter-thick branch can be cut in two.

After getting seven or eight branches, I hurried back to the river, trimmed all the branches first, cut them into smooth round shapes, and laid them on the front of the raft.

Then he dug a small hole with a paratrooper knife on the ground at the tail of the raft. Li Jianrui took out a mowing stick, inserted it into the hole, and pried it hard. The raft slowly moved forward. Li Jianrui continued to use force until the raft climbed up. After he laid the wooden rails, he stepped on the ground with one foot, stepped on the back of the raft, and pushed forward.

Sure enough, the raft moved easily on the cylindrical wooden rails. The more troublesome thing was that he had to look at the wooden rails in front of him, stop when he ran out, and then take out the round sticks from under the raft and spread them in front of the raft. .

When the front part of the raft entered the river, Li Jianrui clearly felt the force of the water flow. He hurriedly inserted the mowing stick on the raft, clasped the stick with his thumb, and hooked the other four fingers to the knots on the raft. Holding on to the edge of the raft, the explosive power of your legs pours into your toes, and you push hard.

The raft led Li Jianrui into the pale green torrent, and the lightly flipped water splashes were instantly carried away by the torrent, and rushed downstream.
