Global time travel

Chapter 46 Pure Land

Before the sun set, Liu Zhi stopped at a place suitable for camping. While everyone was lighting a fire to barbecue, he went to dig a pile of clay and came back. First, he made a small hole in the ground, threw some twigs in it, and started a fire. , and then surrounded by strips of long and thick clay, layered on top of each other, and soon a circular clay furnace was made.

There is a hole with a diameter of more than ten centimeters on the side of the clay furnace, which fits the soil pipe he made yesterday.

After dinner, Liu Zhi called Chen Da and tied three thick wooden sticks of similar length together to make a door shape. Tie the hemp rope inside, and tie it to the front end of a branch, making it look like a whip used to drive cattle and sheep on earth.

Then, Liu Zhi put the handle of the windmill through the bottom of the earthen pot, turned the earthen pot upside down, covered the mouth of the pot on the ground, connected the circular earthen pipe to the mouth of the earthen pot, and aligned the earthen pipe with the hole in the earthen stove. Keep rubbing the handle of the windmill, and the fan blades made of two pieces of bark in the earthen pot will rotate continuously, delivering a large amount of wind power, which will be "blown" into the earthen furnace through the earthen pipe, making the firepower in the earthen furnace extremely strong. strong.

Chen Da was stunned, and murmured, "Brother, are you a bellows?"

He has seen bellows in his hometown in the countryside, and he still understands the principle of it.

Liu Zhi nodded: "Almost, I call it a bow blower."

Bow blower?Chen Da recited it silently in a low voice and then asked: "What does the bow posture mean?"

Liu Zhi smiled, and took the "door" made of three wooden sticks. The two doorposts were inserted on both sides of the clay pot, and the handle of the windmill was right in front of the small hole in the "top of the door", because he had already placed the "door" in the clay pot. A small wooden board was cut out, and a small hole was also cut out in the middle of the board, and the position where the top of the windmill supported happened to be this small hole, so the whole windmill was fixed between the top of the door and the two small holes in the wooden board, and would not move outside. .

Then, he picked up the freshly made whip, wrapped the hemp rope around the handle of the windmill, straightened the rope, held it in his hand together with the end of the stick, and pulled it back and forth slowly, and the rope drove the handle of the windmill Spinning at a high speed, the flame in the earthen furnace continued to rise, and the temperature rose sharply.

Liu Zhi turned to Chen Da and said, "See, this is the so-called bow pose. No matter I pull or push, the fan blades inside will rotate quickly. Because the fan blades are straight, wind will come out when they rotate forward and reverse. There will be no interruption, achieving an effect similar to that of a blower."

Seeing the flames in the clay furnace continue to rise, Chen Da only felt his eyes opened. He heard from his grandfather that the traditional bellows can also achieve the effect of a blower, but this requires a very complicated design, and Liu Zhi used clay Raw materials such as , branches, bark, and straw ropes are completed, which is really amazing.

"Well, brother, this thing is for holding, but what's the use?" Chen Da asked the last question.

"Fire a long spear, the kind Zhao Yun used." After Liu Zhi finished speaking, he went to the side and picked up the trunk of the hexagonal tree, and said to Chen Da: "Do you know how hard this tree is?"

"I only know...it's very hard." Chen Da said sullenly. He had heard about Liu Zhi killing the dog demon with a branch, and he had personally tested the weight of that branch. He bench-pressed it at school. It can reach 80 kilograms, not counting the barbell, but even with the strength of breastfeeding, it can't lift the branch that is less than two meters long and thicker than an arm. It can be seen that its density must be frighteningly high.

"Let's put it this way, this kind of tree not only surpasses platinum in terms of density, but also surpasses diamonds in terms of hardness." Liu Zhi said, laying the trunk on the clay stove, and turned to Chen Da and said, "Go and help me pull it." Blower, just do it like I did."

Chen Da snorted, sat next to the blower and kept pushing and pulling, and continued to ask: "So, you want to make this trunk into a spear? By the way, I remember that diamond is the hardest substance on earth, right? Are trees really that hard?"

"Well, I want to use this to make a spear, and..." Liu Zhi lazily replied: "Diamonds are not the hardest substance on the earth. They are all hyped by merchants. They are a marketing tool. In nature, there are two kinds of minerals that are harder than diamonds, and there are even more artificial ones.”

Chen Da looked taught, and thought for a while: "Brother, since this tree is so hard, it might be useless to just burn it with fire?"

"Ordinary fire is indeed useless, but it is different with a blower. It only needs a temperature of [-] degrees to burn its surface to a little bit of carbonization. The higher the temperature, the faster the efficiency." Liu Zhi explained. One sentence.

"So, wouldn't it take a long time to burn?" Chen Da said.

"Well, it takes about four to five days to burn out the gun barrel, and it takes about that long to grind the gun head and handle, which adds up to about ten days." Liu Zhi replied that the low ignition point can be said to be the only unique feature of hexagonal wood. Disadvantages, once you encounter a fire-breathing monster or a special awakened person who can control fire, this weapon is easily damaged, but repairing it is impossible due to material limitations, and it takes time and effort to transform and re-create it. Compared with rare metals, it is really not a good weapon material.

…………

For the next three days, under the leadership of Liu Zhi, the people traveled during the day and rested at night, and finally arrived at the camp in the valley at noon on the fourth day.

At this time, the trees around the camp had been cut down, and the stumps were uprooted to make various tools. Rows of wooden beds stretched out at the bottom of the cliff, more than [-] meters long. The wooden beds were covered with straw mats and straw pillows. , On the very few wooden beds, there is a piece of animal skins that are neatly folded and washed exceptionally clean. It looks like the bed of a big man.

Around some of the beds, there are wooden tables and chairs, and tools such as stone tools, pots and pans are placed on the tabletops, both pottery and wood, and most of them are wood.

In the middle of every ten beds, there is a large pottery vat with a height and width of one meter. A round wooden board covers the top of the vat. From time to time, people will be seen carrying wooden ladles to drink water, presumably it is boiled water.

In the open space on the left side of the camp, there are nearly forty earthen stoves, and twenty or thirty men and women are busy there. In addition to clay pots and steamers, there are also exquisitely polished stone pots for cooking utensils. You can smell the aroma of cooking and soup from a long distance.

Looking outside, there are more than ten neatly arranged cabins on the left and right sides of the camp, about two meters high and 1.5 meters wide, with doors and roofs. From time to time, people rush in anxiously, and soon they look relaxed. When you walk out, you will undoubtedly find the toilet.

There are several mud houses on the hillside not far from the camp. White mist is rising from the chimneys on the roofs, like some kind of workshops.

This scene swept away the exhaustion of the people who had been marching for four consecutive days. Even the wild fruits and wild vegetables on their shoulders seemed to be much lighter. Thinking about living in such a place in the future, working hard every day, not Worrying about food and lodging, and even having the opportunity to become a superman-like awakened person, many people couldn't help their eyes flushing, and a very few people with sensitive temperaments already had the tip of their noses twitching and tears streaming down their faces.

Although Liu Zhi had revealed the situation in the camp to some extent, many people still couldn't help crying when they saw such a pure land. This was a scene that only appeared in their dreams since they crossed.
