(October 20) countdown to the 71st day

There was a dawn in the canyon, and Yao Xiaoyi held the raft and continued to go south without stopping.

On the way, the process of landing on the island by a detachment of eight killers was clearly recorded by the camera set up on the island, and one of the killers strayed into Yao Xiaoyi's carefully designed trap, and the process of being successfully poisoned naturally did not escape Yao Xiaoyi's eyes. One less of the eight killers.

But the speed at which they traveled was much faster than Yao Xiaoyi expected. In about three hours, they came to the island from the river beach, and Yao Xiaoyi spent four full hours on the same waterway. Counting the time that these killers have been delayed on the island, the time difference between her and the killers is still about four hours.

Walking forward against the morning light, Yao Xiaoyi took out the map left by the old man Tang Ji.

On a simple map, the thickest line winds up from the bottom left corner to the top right corner, and when it reaches the top right corner, it turns and stays in the middle of the top part of the map. Obviously, this thick line is the river channel in front of you that runs from north to south. The starting point of this thick line should be the exit of the secret passage halfway up the back mountain. About two fingers away from the starting point, a small island was marked, the one in the middle of the river she had passed.

According to the trend of the river, referring to the map, combined with the time spent on the waterway, she can judge that the position she is now is from the island, and the position from the starting point is about the same as the location from the island, even if she takes into account that the sketch drawn by the old man Tang Ji in a hurry will have a little error, this error range will not exceed half an hour's journey.

If you look at the whole thick line, the current position is less than one-fifth of the distance to the end shown on the map. In this way, it will take at least four days to reach the unknown end, and at the speed at which the killer is traveling, it will not take them four days to catch up with them.

In this way, the plan of waiting for the finish line and then dealing with the other party must be revised.

The river was in a deep canyon, and the river was mostly lined with steep cliffs, making it extremely difficult to climb and escape along the cliffs, and more importantly, another group of eight killers had climbed up the mountain along the rocks at the river beach in pursuit, and she was not sure if they would go up the mountain and chase them down the river along the ridge.

Unable to move along both sides, the current river is a one-way street, which means that she and the killers chasing along the river will have to encounter, and this river will be a battlefield for her and the seven killers who follow her.

If there is a battle in the end, you have to plan ahead, at least as much as possible to eliminate the opponent's living force before the decisive battle.

She put away her map and continued south, trying to find a suitable ambush site.

Not long after, the raft turned another corner, but saw that the river channel suddenly narrowed and the current accelerated. On the left side of the front, a huge rock protrudes from the edge of the cliff, about 3 meters high, and the protrusion is more than 5 meters, and it is abruptly blocked in the middle of the river. The river was forced to turn right again in a large arc, and after rounding the boulder, it made another left turn of nearly 180 degrees, making this section of the river show an S-shape with a large arc.

Approaching the rocks, Yao Xiaoyi approached the left bank of the raft, looked around, and decided to choose this section of the river as the ambush site. Looking at the time, it is estimated that there is still a three-hour time difference between the pursuers, which is enough for her to be fully prepared.

She carried the raft back to the point where the rock protruded from the river, tied one end of the rope into a slipknot and tied it to a tree growing in a gap in the rock, and then took the raft to the other side of the river, compared the height, and tied the other end of the rope to a tree.

She pulled out an improvised launcher from her backpack. This device is a bow and crossbow, which is a little smaller than the one she is using, but the length of the arrow groove is the same as the arrow used by Yao Xiaoyi, the difference is that this device has a built-in smart chip, which can be wirelessly connected to the mobile phone, which can be used for her to adjust the firing angle and trigger the firing from a distance. The downside is that you can only use one arrow at a time, and you can only kill one target at most. Moreover, according to Yao Xiaoyi's expectations, waiting for the shooting to be completed, she has no chance to retrieve this device. She couldn't care about so much, loaded an arrow, adjusted the angle, fixed the transmitter on the right bank of the river, connected it wirelessly with her mobile phone, and adjusted it.

Immediately, she made a 180-degree turn around the raft along the river, parked the raft behind the boulder, climbed over the 3-meter-high boulder, came to the tree where the rope had just been bolted, sank the rope into the water, tied a dead knot, and then took out a rope bolt with one end tied to the rope across the river, and the other end hung behind the boulder, for her to pull the rope at the critical moment and bring the rope hidden in the water out of the water.

She found a suitable spot on the boulder and mounted the camera, which was pointed downstream of the big bend.

Next, she needs to prepare wooden arrows. With only 8 arrows left in the quiver holster, she must use more arrows in order to deal with possible more killers.

Cut the appropriate branches with a machete, compare the length and thickness of the real arrows, and soon ten wooden arrows will be polished. After checking her phone's information, she drove a nail into the tail of the wooden arrow - there is no doubt where she got the nail, if you look at the various small items of betel nut in her backpack, you can know how well prepared she is - to improve the flight speed and stability, then wrap a layer of aluminum skin in the tip of the arrow, and then sharpen the arrow on the rock to improve the penetration.

When the wooden arrow was ready, she opened her bow and shot an arrow at a tree 500 meters away, and then shot an arrow at a tree 800 meters away. Before she was done, she took out two more arrows that had been matched with iron, aimed at the two trees she had just shot, and shot two arrows accurately. She came to the two trees one after another, carefully compared the depth of the two arrows, and came to a preliminary judgment that at a distance of about 500 meters, the shooting effect is almost the same, and about 800 meters, the lethality of wooden arrows is slightly inferior. To do this, she also smeared the arrows of wooden arrows with poison mixed with hallucinogens. Through the practice of poisoning the killer on the island, it has been proved that as long as the target is hit and the blood is seen, the opponent has almost no chance of survival.

Once she was ready, she deduced the course of the upcoming battle and found many loopholes. For example, what if the wooden arrow doesn't achieve the desired killing effect? Her plan was to shorten the shooting distance, and if it didn't work, use real arrows; For example, what if you can't attract your opponent to the other side? Her plan was to pull another rope so that she could pull the woods on the other side and make noise.

After repairing the possible holes, she climbed the boulder again, selected three excellent firing points, and aimed at the predetermined design target on the river surface, between the three firing points, she could quickly and covertly move within 2 minutes.
