Since the plan is to cross the river, it is necessary to find a way to cross the river. It is impossible to make a decent boat, and they don't have that ability combined, so they retreat to the next best thing, and prepare to make a simple raft with local materials, as long as it is strong, there should be no problem in crossing the river surface of more than 100 meters.

That night, Yuan Si, as the captain, gathered the team members together for a meeting to discuss. After all, it was the first time they had done a raft, and the materials and technology still needed to be discussed.

Yuan Si let everyone express their opinions, although except for Yuan Si, no one else has made their own rafts, but they were all soaked in the river or pond when they were children, and they all have some opinions about things like rafts.

In the end, Yuan Si saw that it was messed up, and there was a faint tendency to go off-topic, so she quickly began to popularize the knowledge about rafts for everyone.

"The most important thing in making a raft is to choose materials, which can be kept floating on the water. There are many materials that can be used to make rafts, such as reeds, balsa wood, bamboo, etc......"

Before Yuan Si finished popularizing science, Xiao An raised his hand curiously and asked, "Captain, what kind of wood is Bashamu?"

"Basha Mu...... Yuan Si felt that they might not understand it if they said too much, so she chose the simplest explanation: "It is a very light wood, it grows fast, the trunk is tall, the leaves are a bit like sycamores, the flowers are a bit like hibiscus flowers, and the fruits are like cotton ......"

The team members still heard it in the clouds, looking like they didn't understand, what is the lightest wood, isn't the wood all the same, why is it still light and heavy, and the trunk is high, they looked at the big trees around them vaguely, the trunks are dozens of meters high.

In one person, they said that the leaves were like sycamores, what is a sycamore, they have never seen it. Even they haven't seen hibiscus flowers, but they've seen cotton.

"It is the lightest wood in the world, it has good floatability, it is easy to move, cut and operate, it is one of the most suitable materials for making rafts, and its bark is easy to peel off into strips, which can be used directly as a rope to tie rafts. But we've been patrolling several times before, and I haven't seen any of these trees along the way, so I don't need to think about this kind of raft. Yuan Si said.

"Ah, then don't talk about it, Captain. Xiao Chang hurriedly said.

"Then I use bamboo, but the bamboo forest is on the other side of the river, not here, and I don't think I will need it this time. "Standing on the river, you can see a large bamboo forest on the opposite side, but they are on this side of the river, and they can only quench their thirst.

"Then what materials can we use now?" asked Xiaowei, and it didn't seem to work to put it mildly.

"Wood. Yuan Si glanced at him, and felt that such a simple question still needs to be asked, it is really a good mallet, "We are in the forest now, there is not much wood, let's make wooden rafts." ”

"Okay, let's make a wooden chop. "Everyone was afraid that the captain would say something out of his mouth that they didn't understand, so they cooperated and shouted, and that's it.

After eating early the next morning, all the team members moved.

Everyone went to the vicinity to look for relatively straight and thick branches, and soon found a lot, after all, it was in the woods, and there was no shortage of these materials.

Then Yuan Si taught, and several other people began to make wooden rafts on the spot.

In fact, the floatability of wooden rafts is not very good, and they do not have padding that can increase buoyancy, so making wooden rafts is not the best choice.

It's just that the materials are limited now, so I can only make a wooden raft first, and deal with sending people to the opposite side, which is a bamboo forest on the opposite side, and then use bamboo to make a bamboo raft with good buoyancy.

The designers all have the heart to deal with it, and you can imagine how rough this wooden row is.

Six pieces of wood about ten centimeters in diameter are lined up, as many branches as possible are placed vertically on top, the thick wood below is completely covered, and then fixed with withdrawn vines, and a simple wooden row is ready.

Everyone worked together to push the wooden raft into the water, and Yuan Si was the first to stand up.

"Okay, you guys wait here first, the wooden raft is not buoyant enough, let's cross the river twice. ”

So they crossed from one side of the river to the other side of the river in two parts.

When everyone reached the other side, Yuan Si had the rafts dragged ashore and dragged into the woods to hide.

This thing can't be put on the river, not because it's afraid that it will float away by itself, but because it can't provide convenience to the enemy, and the enemy sees this thing by the river, and uses it to sneak across the river isn't it to make trouble for his own people. So you have to hide it and pull it out when you use it.

When they arrived, everyone packed their bags and continued their patrol mission. However, their goal was clear, and they went directly in the direction of the bamboo forest. Because Yuan Si is still thinking about the bamboo raft.

On the opposite bank, I saw that the bamboo forest was on the opposite side, but when I really got to the opposite side, I found that the bamboo forest was not right in front of me, and there was still a short distance to walk over.

Yuan Si took the team for a day, and then arrived at the bamboo forest, she looked at her watch, it was only five o'clock in the afternoon, and said: "Okay, let's rest here today, I will take two people to patrol the neighborhood to see if there is any danger, Xiao Chang, you take someone to take tools to the bamboo forest to order bamboo." Let's make a bamboo raft before it gets dark. ”

Yuan Si was not very satisfied with the wooden raft she had made earlier, so she thought about using bamboo to make a sturdy one.

"Yes. Xiao Chang didn't know why the captain was so attached to the raft, but since the captain had given the order, he had to complete the task.

So the two groups went their separate ways.

Yuan Si took Xiao Wei and Xiao Wang and carefully inspected the three hundred meters in diameter around the campsite they were preparing to camp. They all knew in their hearts that this side of the river was more dangerous than the other, and for their own safety, they could not let go of any trouble.

Fortunately, their luck was not bad, this bamboo forest was very large, and they did not find any danger in this area where they wandered. In the process of wandering around, Yuan Si also bundled her spiritual power into a bundle, and as she moved and kept probing outward, it could be determined that within the diameter of five hundred meters of the temporary station, no enemy troops were found, and this area should be safe.

After walking around, the tense bodies of several people relaxed a little.

"Captain, safe nearby. Xiao Wang reported.

Yuan Si nodded.

"Safety is safe, but after walking this big circle, why haven't you seen any wild things, what are we going to eat at night?" Xiao Wei grabbed his hat and fanned the wind, feeling a little depressed.

The weather here is really hot, it's still February, and the mountains are still covered with snow in his hometown, but it's a hot weather of more than 30 degrees here, so where can I make sense. The main thing is that he feels that he is going to eat bran vegetables at night, and his heart is not very happy.

Now they have formed a rule, when they come out, the compressed grain they bring is eaten as a staple food, there is no time to cook at noon, take a bite, if there are no special circumstances every night, they will patrol around, and play some game that can be eaten for dinner.

This work is also done by everyone in turns, but it is recognized that on the day when the captain is in charge of patrolling, their food will obviously be much better.

I thought that the captain would be able to improve the food today, but I didn't expect that there was nothing in this bamboo forest except bamboo.
