With the help of these young men, the construction speed of our homes has been greatly improved. The lads quickly got busy, and they split into several groups. There are people who help build houses, and there are people who help find food. Liang Cheng led people to find the man-eating grass, and he said that by connecting the hollow vines in the man-eating grass to make a water pipe, he would not have to draw water from the puddle every day. Lao Mai also followed, he attached great importance to water, and said that he should master this technique himself.

The lads gave us some of the food they had brought with them, which were dry rations they had brought with them when they went out. There are mainly dried fish, jerky and some handmade pastries. Dabao is very interested in these foods, and Sihan also explained the method of some dried products, such as dried fish soaked in water for half an hour, not too much.

Some people also went to the beach to catch fish, and I followed. They threw the round, flattened cage made of vines they had with them into the water, and after a while they brought it up to look at it. Heaven favored us very much, and from time to time arranged for a few fish to swim into the cage, and when they saw the fish, the boys couldn't stop laughing.

I think this cage is good and I want a few to use for myself, and the boys agreed to come down in one bite. Tell me how to use this cage they call "quack". This kind of cage also has a large opening on it, and the circle is made of plant teng strips to form a net. It's filled with bait and you can see it from the outside. Crabs or small fish basically go out after entering the opening, and you can catch them.

After fishing and returning to the tree house, Si Han expressed his high appreciation for the tree house we built. After appreciating Sihanmeng, the first question made me almost sit on the ground.

"Brother Jingtian! You also live in this kind of house on aliens? ”

"How so? This house is really the most primitive and simple wooden house built because there are no tools, combined with the on-site environment. In modern society, even wooden houses are made of fairly regular wooden posts, beams, and planks. The cross-sectional dimensions of the wooden columns are 250*550 mm, and the cross-sectional dimensions of the beams are 250*600 and 150*400 mm. The width of the plate is 400, the thickness is 30. ”

"No other sizes? There's never just one style of wooden house, right? Sihan continued to ask.

"There are many styles, but the cross-sectional dimensions are only a few of the ones I mentioned, which is called standardized construction. These dimensions of wood are processed by robots in machines according to the standard, and the precision is very high. However, in order to meet the needs of different people, there are as many as 18 house styles to choose from. There are retro, minimalist, natural, modern, and so on. However, there is one feature: they are all made of standard building materials, and the house construction robot is used for fast construction. These building robots already have eighteen house builders in their arsenal, and if you choose any of them, they can be built at a very fast pace. Do you know how long it takes to build those robots for the same size of wooden house? Sihan asked these questions, and I couldn't help but want to test him.

Sihan squinted, thought for a while, and said, "Three days? ”

I smiled and shook my head. "One day?" This time, Sihan's voice was a little quieter.

"Three hours!" I didn't want to torture this lad anymore, gave the standard answer.

"It's so fast, even if it's a big house building block, it takes more than three hours!" Sihan's mouth has changed to a standard O-shape.

"It seems to be the same, but the speed is so fast, these robots were designed by us to specialize in this, and the efficiency is quite high!" When I thought of such an efficient robot, and the treehouse in front of us that took so much time, I had the idea of returning to modern society as soon as possible.

"Brother Jingtian! I heard Sister Hongyin say that you also participated in the war, what does modern warfare look like? Sihan gave up the question of building a house, and his thoughts jumped quickly, asking some questions that children regarded as games.

"How did you think to ask this question, do you think war is fun?" At the thought of the flames of battle against the Red Flame Star, my heart tightened unconsciously, and a smile faded from my face.

"No, no, I'm just curious! Grandpa Kong often said to us, 'Soldiers, treacherous ways!' The major affairs of the country, the life of death, and the way of survival must not be ignored! I'm just curious, modern warfare has long been an information-based war, how can it be tricky? What's the trick? Sihan explained again and again, but asked one of the most troublesome questions for modern warfare commanders. This problem has been studied by modern soldiers, but in the end there is still no big result, and people still prefer simple and violent mecha crushing tactics in land warfare.

"You're right, modern warfare is an information war with highly developed information, and even individual soldiers are equipped with a global information individual soldier system, and every mecha is armed to the teeth! And the question you asked was the first officer or soldier to ponder. This is too complicated to say, and there are some things you don't understand, but one principle is to eliminate or weaken the enemy's reconnaissance means and improve your own reconnaissance capabilities. "I explained it briefly, and I actually avoided talking about it.

Sihan was obviously not satisfied with my answer, and his eyes were spinning. Seeing his eagerness, I turned to a brief introduction to the composition of the soldiers and some tactics of the Marine Warfare system.

"Why do you only lead fifteen mechs, and why can't you bring more?" Sihan's questions kept coming at me like cannonballs.

"This number is the empirical data obtained from long-term wars, and fifteen per person can ensure that the first team member has enough combat effectiveness, and can also ensure that the team members can command the mechs below more reasonably. Mecha is actually a subordinate of the team members, but in fact, the tactical literacy of some team members is not enough, if they are placed in the previous war system, they are only worthy of being soldiers and cannot command anyone. But now that the mecha is in charge, each team member must be equipped with a mecha, if there are too many, those unqualified team members command too many mechas, and they will only fearlessly increase the consumption of mechas. In this respect, fifteen are a bit much. But fortunately, each squad has a team leader, and the quality of this team leader is quite good, which to a certain extent makes up for the possible wrong command of the team members below. That's why there are 3 people in each squad in the alliance, and each team is equipped with 15 mechs! "I had thought about this for a long time, and I said what I thought without thinking.

Listening to my explanation, Sihan began to think again, this time thinking for a longer time, and finally did not ask questions like a barrage, which also made me breathe a sigh of relief.

"Jingtian, Jingtian!" The old but majestic voice rang in my ears, and I looked in the direction of the sound, only to see that Lao Mai and Liang Cheng were already about twenty meters in front of the tree house. Lao Mai beckoned desperately to me, and I quickly pulled Sihan over.

The old man had a circle of man-eating vines in his hands, and Liang Cheng was holding a sucker head that sucked the grass, and after a while, he stuffed a long vine branch into the long suction head, and then pinched the suction head. A miraculous scene occurred, the suction cup suddenly clenched the vine branch as if it were alive, and our water supply channel was extended by several meters.

"Whew! This man-eating grass can be connected like this! "I had a crush on this man-eating plant for the first time, and I didn't expect it to be so easy to connect.

"Yes! Don't look scary, it's full of treasures. When it dries, it forms a hollow pipe, which we use as a water pipe at home. Its rhizome can also be eaten, this suction cup head can be used as medicine, the antidote after being bitten by it is to use the suction cup head to dry and take out the gum in it and grind it into powder with the seeds of another plant, Hongling. Liang Cheng introduced, saying that we can't catch up with the natives born here when we understand the animals and plants here.

Liang Cheng continued with his hands and feet, and then led the vines to the tree house. The pipes were connected, and I quickly asked Dabao to pick out a large bucket from the spaceship. We had already turned over the spaceship when we were looking for a water container, and there was no one on the small bucket spaceship, but the large bucket finally found one for us. This bucket was originally for food, but it was empty when the food was eaten.

We put the last section of the pipe on the side of the barrel, Liang Cheng took out the bow behind his back, and picked out a huge arrow from the simple quiver and put it on the bowstring. I already knew what this arrow with a huge arrow was, but Lao Mai and the others didn't know, they only knew that they looked up and watched Liang Cheng shoot up almost straight towards the sky.

"Whew!" The whistle made a loud sound and shot into the distance, and it brought a signal to people in the distance. After the shot, Liang Cheng kept staring at the sky, and the whistle soon fell, Liang Cheng ran over as soon as possible, picked it up, wiped it clean, and then received it into the quiver. I stood still by the vat, and the people on the other side of the pool would start to release water when they heard the sound of the horn. Sure enough, after about three minutes, the vines began to bulge, and a clear spring emerged from the vines.

Liang Cheng picked up the vines that came out of the water and examined them carefully, but he didn't put them in the bucket for the first time. At first, the water that came out was slightly green, because the water flowing through the vines brought out some of the impurities inside. After about half a minute of flowing, the water became completely clear, and Liang Cheng put the vines into the vat. Because the diameter of the pipe is slightly smaller, the water is still relatively slow, and it is estimated that it will take a day and a night to slow down the whole bucket.

A pool of clear water is a pool of hope, which is the beginning of a better life here. This clear water attracted people like a magnet, and everyone who came was smiling, laughing and playing. They held the trickle in the palm of their hand and rushed to the person beside them, and the person who was caught in it did not chagrin or hide from it, and allowed the water of hope to soak his whole body, as if his whole body would be filled with hope.

The ghost blows the lamp
